Patent Application
20220362723
This application relates to brine making and, in particular, to brine makers and/or operation thereof.
Present brine makers suffer from a variety of drawbacks, limitations, and disadvantages. Accordingly, there is a need for inventive systems and methods described herein.
The embodiments may be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale. Moreover, in the figures, like-referenced numerals designate corresponding parts throughout the different views.
In some examples, a brine maker is provided comprising one or more of the following features:
In other examples, the brine maker may have none of the features listed above.
Device and process overview: A high efficiency brine maker is described herein. The brine maker converts rock salt into a brine solution, which in at least some examples, may have a high concentration of salt. There are various devices on the market that range from up-flow, down-flow, and side-flow brine makers. Each of the types of brine makers have merit and drawbacks. Typical bulk salt used to control roadway ice varies in gradation (salt crystal size) and in amount of waste (insoluble matter in the salt). Therefore, a brine maker that may efficiently produce a high concentration solution regardless of salt gradation and with low salt levels (solute) in the hopper by be desirable.
Production of large volumes of solution at a high concentration is generally desired in order to satisfy the needs of the users. Because the concentration of the solution is typically 23.3% or higher, having a brine maker that efficiently converts solvent, such as water, into a high concentration brine solution is desirable. Thus reducing labor and increasing productivity.
Ease of operation may be a desirable aspects of a brine maker. Alternatively or in addition, desirable aspects of the brine maker may include: ease of loading the device with bulk salt with a loader bucket, clean-out of waste such as insolvable material build up, and efficiently producing a high concentration solution regardless of solute levels.
The brine maker described herein may make high concentration solution efficiently, reduce waste, ease of cleanout and compact, provide a full size opening for loading salt, and direct salt to a narrow dissolving chamber.
Alternatively or in addition, the brine maker may facilitate easy loading of the brine maker with loader bucket, have high capacity with small foot print, efficiently dissolve solution to make a strong concentration, and/or dissolve as much solution as possible so that labor for cleanout of waste is minimized. For example, the hopper may be 5 feet wide, 10 feet wide, or any other suitable width.
The hopper 102 has a top opening configured to receive a solute from above the brine maker 100. As explained further below, the hopper 102 also functions as a brining chamber. The hopper 102 may be constructed of stainless steel. Alternatively, the hopper 102 may be constructed of polyethylene and/or a polyethylene composite. The polyethylene hopper may be made, for example, using a rotational molding process.
Referring to
The partition screen 202 may include an upper screen 204 that is slanted. The upper screen 204 may be slanted so that the upper screen 204 directs the solute, which may be dumped into the top of the hopper 102, into the solute side 208 of the hopper 102 instead of permitting the solute to fall into the brine side 210 of the hopper 102. In some examples, the upper screen 204 may be coupled to the rest of the partition screen 202 by a hinge 206. The upper screen 204 may swing open at the hinge 206 in order to provide access to the brine side 210 of the hopper 102 from the top of the hopper 102.
Referring to
The solvent ports 214 are configured to direct the solvent across the bottom floor 224 toward the partition screen 202. For example, the solvent ports may be configured to direct the solvent substantially parallel to the bottom floor 224 of the hopper 102.
In addition to the solvent ports 214, the brine maker 100 may include multiple return ports 214 in some examples. The return ports 214 may be arranged just above the bottom floor 224 of the hopper 102. For example, the return ports 214 may be located within 2 inches of the bottom floor 224. In other examples, the return ports 214 may be located within 1 1/2 inches of the bottom floor 224.
The return ports 214 are configured to direct a brine solution into the solute side 208 of the hopper 102 toward the partition screen 202. The brine solution directed by the return ports 214 may be a brine solution generated by the brine maker 100 that has a concentration of salt which is out of tolerance. The concertation of salt may be out of tolerance, for example, if the brine solution has too much or too little salt relative to a target salt concentration.
As shown in the illustrated example, the return ports 214 and the solvent ports 214 may be arranged linearly along the bottom floor 224. Each one of the return ports 214 may be adjacent to a corresponding one of the solvent ports 214. In alternative examples, any other distribution of the return ports 214 among the solvent ports 214 may be implemented.
The hopper 102 may include a sloped floor 212 at the bottom of the hopper 102. The sloped floor 212 may extend the length of the back of the hopper 102. The sloped floor 212 may slope downward toward the bottom floor 224 of the hopper 102. The sloped floor 212 may extend all the way to the bottom floor 224. Alternatively, such as in the illustrated example, the hopper 102 may also include a substantially vertical wall 228 that extends from the bottom floor 224 of the hopper 102 up to a bottom edge of the sloped floor 212. The solvent ports 214 and/or the return ports 214 may be located in the substantially vertical wall 228. Alternatively or in addition, the solvent ports 214 and/or the return ports 214 may be located in the sloped floor 212.
By including plumbing outside of the hopper 102 —which also functions as a brining chamber—the hopper 102 remains free of any plumbing. In other words, no pipes or other plumbing are located in the hopper 102. This makes the hopper 102 (and also effectively the brining chamber) easier to clean out.
Examples of plumbing may include pipes, hoses, manifolds, and other fixtures used to transport fluids. For example, the plumbing may include a solvent manifold 220 fluidly coupled to the solvent ports 214. As another example, if the brine maker 100 includes the return ports 214, then the plumbing may include a return manifold 222 fluidly coupled to the return ports 214. The solvent manifold 220 may include, for example, a pipe comprising fittings arranged at regular intervals along the length of the pipe, where each one of the fittings may be fluidly coupled to a corresponding one of the solvent ports 214 with a hose (not shown). The return manifold 222 may include, for example, a pipe comprising fittings arranged at regular intervals along the length of the pipe, where each one of the fittings may be fluidly coupled to a corresponding one of the return ports 214 with a hose (not shown). The plumbing, such as the solvent manifold 220 and/or the return manifold 222 may be located in the area 226 below the sloped floor 212. Alternatively, the plumbing may be located anywhere outside of the hopper 102.
During operation of the brine maker 100, the solute, typically bulk rock salt (NaCl), is loaded into the hopper 102 via a loader bucket (not shown). The loader bucket may be on a tractor, for example. The hopper 102 may be partially or fully filled with the solute. Loading the hopper 102 with the solute using a loader bucket is not precise; therefore, having a larger opening to the hopper 102 reduces overspill and enables the operator to rapidly fill the brine maker 100. The brine maker 100 having a relatively large opening and yet still having a relatively small footprint may help reduce space and increases functionality. These features may make dumping material into the hopper easier.
The upper screen 204 of the partition screen 202 is sloped downward and inward. Therefore, the upper screen 204 deflects and feeds the solute into the solute side 208 of the hopper 102. In addition, the left-to-right dump width (length of the longitudinal axis of the upper opening of the brine maker 100) is substantially the width of the brine maker 100. By having a dump opening width and depth (length of the opening in a direction perpendicular to the longitudinal axis of hopper 102 and/or the brine maker 100) that are substantially equal to the footprint of the entire brine maker 100 ensures that the dump opening for loading the brine maker 100 with bulk product via a loader bucket may be as efficient as possible.
The sloped floor 212 on the solute side 208 of the hopper 102 further funnels the solute to a narrower area at the bottom floor 224 of the hopper 102. The solvent entering the hopper 102 via the solvent ports 214 begins to dissolve the solute to form a brine solution. In some examples, the ports 214 may be located as low as possible to effectively produce a brine solution even when low amounts of solute are present and to dissolve as much solute as possible without waste.
As mentioned further above, the partition screen 202 separates the hopper 102 into 2 portions: the solute side 208 with “Rock Salt” and the solution side 210 comprising NaCl Brine solution. The solvent enters the hopper 102 through the solvent ports 214 that use conduit (not shown) connected to the solvent manifold 220. A flow of the solvent through the solvent ports 214 substantially erode the solute to form the brine solution. The brine solution passes through the partition screen 202 into a chamber of the hopper (the brine side 210) where the brine solution gathers. Liquid level sensors, a low float 216 and a high float 218 sense lower and upper liquid levels respectively. The level sensors 216 and 218 may be in communication with a pump or other control device(s) that control the flow of liquid into and/or out of the brine maker 100. The level sensors 216 and 218 may provide an indication if the brine solution is sufficiently high enough (above the low float 216) to pump or if the solution level is high enough (above the high float 218) to stop the flow of solvent into the hopper 102.
The side-flow design together with the partition screen 202 may be an advantage of the hopper. In the illustrated example, liquid level sensors 216 and 218 are in communication with solvent inlet controls, manual or automated, to ensure the liquid in the hopper 102 is substantially kept from filling the hopper 102 entirely. The low float 216 helps when adding more solute into the hopper 102 because the liquid in the hopper 102 may be displaced when adding the solute. The liquid in the hopper 102 may be kept at a lower level around the level of the low float 216. Keeping the liquid at the lower level may reduce spillage of the brine solution outside of the hopper 102.
The partition screen 202, which may run the entire vertical height of the hopper 102, allows the brine solution to pass from the solute side 208 of the hopper 102 to the brine side 210 of the hopper 102 regardless of waste buildup in the hopper. The waste buildup may plug the partition screen 202 at various locations with debris. Thus, as insoluble material builds up at the bottom of the hopper 102 on the solute side 208, a portion of the partition screen 202 may become plugged; however, a substantial portion of the partition screen 202 will remain free of insoluble waste so as to maintain a free flow of brine solution from the solute side 208 to the brine side 210.
The brine side 210 of the hopper 102 houses the liquid level sensors 218 and 216 where the solute will not interfere with the operation of the liquid level sensors. The brine side 210 acts as a holding vessel where the velocity of the brine solution is reduced to enable fine unsolvable matter that is in suspension to fall out of suspension prior to the brine solution exiting the brine side 210 of the hopper 102 through the solution outlet 302.
The upper screen 204 may swing open at the hinge 206 in order to provide access to the brine side 210 of the hopper 102 for cleaning and service while allowing solution to pass through the rest of the partition screen 202, thus maximizing, or at least improving, the loading of the solute through the top of the hopper 102.
Undissolved solute may be cleaned out from hopper 102. For cleanout of insoluble material in the solute side 208 of the hopper 102, it may be desirable to first dissolve as much solute as possible and leave remaining insoluble waste materials behind. For ease of cleanout, it may be desirable to have the bottom floor 224 and the hopper 102 free of plumbing, such as pipes and/or other components, because the plumbing may otherwise obstruct removal of debris buildup. For example, this area being free of plumbing enables the removal of waste material by pushing the waste out through the cleanout door 106. Thus, the hopper 102 is free of piping and/or other obstructions to allow for easy and quick cleanout. The brine maker 100 is designed to dissolve the solute at the lowest point in solute side 208 of the hopper 102 with no internal pipe or obstructions.
In a first aspect, a brine maker may be provided that includes the sloped floor 212 in hopper 102 to narrow the portion of the hopper 102 that also functions as dissolving chamber and to funnel the solute to the solvent ports 214.
In a second aspect, ports 214 are located below the sloped floor 212 and at a relatively low point on the substantially vertical wall 228. The ports 214 may run substantially the width of the hopper 102, at the bottom of the hopper 102, and on the side of the hopper 102 having the sloped floor 212.
In a third aspect, the partition screen 202 may be sloped starting at top of the brine maker 100 to permit a full depth top opening for salt dump and for maximizing opening size.
In a fourth aspect, no internal piping or other plumbing is located inside of the hopper 102 to ease cleanout and maintenance.
Other aspects may include any of the following or combinations thereof:
The brine maker 100 may be implemented with additional, different, or fewer components than shown or described herein. For example, the brine maker 100 may include a processor in communication with a memory, one or more control valves, and/or pump(s). Examples of the processor may include a general processor, a central processing unit, a controller, a microcontroller, a computer, an application specific integrated circuit (ASIC), a digital signal processor, a field programmable gate array (FPGA), and/or a digital circuit, analog circuit. Each component may include additional, different, or fewer components.
All of the discussion, regardless of the particular implementation described, is exemplary in nature, rather than limiting. For example, the hopper 102 in the example shown in
In the illustrated examples, the solution outlet 302 is on the right side whereas the cleanout door 106 and the brine side drain 108 are on the left side. However, in other examples, these components may be in different locations.
In the illustrated examples, an upper portion of the partition screen 202 is an upper screen 204. In alternative examples, the upper portion of the partition screen 202 includes no screen.
The directional terms such as “top”, “bottom”, “downward” refer to directions when the brine maker 100 is oriented so as to be operational. The term “substantially” means approximately (within a tolerance of 5 percent).
