The embodiments relate to transportable concrete batch plants and, more specifically, relate to containerized concrete batch plants.
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement that hardens over time. Many types of concrete exist, including cementitious and non-cementitious types, each having different of binding aggregate together. Due to its vast building applications, concrete is one of the most frequently used building materials. In fact, its usage worldwide is, ton for ton, twice that of steel, wood, plastics, and aluminum combined.
A concrete plant, also known as a batch plant, includes equipment that combines various ingredients to form the concrete. Inputs include water, air, admixtures, sand, aggregate (e.g., rocks, gravel, etc.) fly ash, silica fume, slag, Portland cement, or cement paste. The batch plant will also include various components to perform various tasks, including mixers, cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, silos, batch plant controls, scales, and dust collectors.
Portable batch plants are a productive, reliable, and cost-effective means to producing batches of concrete which allow the user to batch concrete in various locations. These systems are often used for temporary site projects. However, portable batch plants are also useful in locations where the equipment size is a factor, or the required production rate is low. Similarly, these systems are employed in locations where the concrete requirements of the job site is not feasibly covered by the inbound transport of concrete mixed at an offsite location.
For this reason, many construction companies utilize a transportable mixing plant that is erected at a jobsite to produce concrete on-site. The transportable mixing plant must then be deconstructed and arranged for transport to the next jobsite at which it is required. This process results in the use of large amounts of resources (in materials, consumables, time, and personnel) to assemble and transport the mixing plant.

The specific details of the single embodiment or variety of embodiments described herein are to a system and method of use. Any specific details of the embodiments are used for demonstrative purposes only and no unnecessary limitations or inferences are to be understood therefrom.
Before describing in detail exemplary embodiments, it is noted that the embodiments reside primarily in combinations of components related to the system and method. Accordingly, the system components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.
As used herein, relational terms, such as “first” and “second”, “top” and bottom”, and the like, may be used solely to distinguish one entity or element from another entity or element without necessarily requiring or implying any physical or logical relationship or order between such entities or elements.
As used herein, the term “concrete element” may include any concrete material including fine and course aggregates, fluid cements (of any type including lime-based cement binder, lime putty, hydraulic cements such as aluminate cement, or portland cement). Concrete elements may also include non-cementitious types of concrete with various forms of binding aggregates.
As used herein, the term “resources” may include various resources utilized by a concrete batch plant and the embodiments herein including water, fuel sources, and other consumables which may or may not be directly used in concrete.
In general, the embodiments described herein relate to a containerized concrete batch plant which is sufficient to form concrete in various locations while being contained within a portable container having standard International Organization for Standardization (ISO) dimensions. The container is suitable for transportation by ship, rail, and truck to a location for deployment. The containerized batch plant is configured to be reusable in various locations without undue assembly and deconstruction between each location. The containerized concrete batch plant comprises a plurality of stabilization outriggers, aggregate intake hopper, a conveyor system to an aggregate dispenser, motorized bin selector for dispenser, concrete elements storage silos, computer controlled actuators for dispensing concrete elements from the storage silos onto a scale, conveying system to an inbound hopper of the mixing drum, concrete pumps, steel concrete pump tubing, concrete hoses, a concrete pump nozzle, an onboard generator, fuel tank, and an onboard computer control system, in addition to standard components included in a concrete batch plant known to those skilled in the arts.
In reference to
In some embodiments, the partitioned aggregate storage silo includes a self-erecting sleeved component 121 (shown in
In some embodiments, the storage silo may be comprised of a plurality of compartments to store the various elements utilized during the concrete formation process. One skilled in the arts will readily understand that various configurations of storage silos may be employed depending on the application of the containerized concrete batch plant at a particular jobsite.
In some embodiments, the concrete pump is configured to receive materials from the intake hopper wherein materials are dispensed.
In some embodiments, the screw worm drive includes a housing having a removeable side plate to facilitate cleaning.
In some embodiments, the concrete pump feeds a concrete conduit having a diameter between 2-5 inches depending on the pump capacity. This allows for the direct dispatching of concrete on a jobsite from the containerized concrete batch plant. In an alternate embodiment, the concrete may be hard-piped into another vertical concrete pump, which is particularly useful wherein the jobsite is a high-rise structure or a similarly tall structure having multiple levels in which concrete is poured. This allows for the direct dispensing of concrete rather than first dispensing the concrete into another vehicle or delivery system.
The concrete elements are transferred from the aggregate storage silos to the mixing drum via a conveyor. The worm drive feeds the mixed concrete elements from the mixing drum to the concrete pump which dispenses the concrete via a hose.
In specific reference to
The container may be structurally modified to facilitate the batching of concrete via the containerized concrete batch plant. For example, as shown in
Each stabilization outrigger may be utilized (whether individually or in combination with one another) to hydraulically lift the containerized concrete batch plant from a delivery truck, to level the containerized concrete batch plant prior to and during use, and to stabilize the working load and moment created when the concrete pump hoses are filled with concrete.
In some embodiments, the conveyor systems are controlled via the onboard computer system by changing the conveyor speed, conveyor direction, and conveyor position depending on the particular concrete element being conveyed.
In some embodiments, the intake hopper feeds the modular conveyor which has a directional spout and selector to feed the storage silos. The storage silos dispense via a computer controller by weight onto a secondary conveyor scale below the silos. The conveyor under the silos feeds concrete inputs into the mixing drum to mix the ingredients and form wet concrete. The mixing drum then outputs the mixed concrete into the screw drive which feeds the concrete pump which pumps concrete into the hose.
