Harvested cotton is baled and stored at a warehouse after it completes a ginning process. These bales may be wet when they arrive at the cotton warehouses for storage. Incidentally, wet cotton bales can spontaneously combust after they are brought to the warehouse for storage, which can lead to disastrous fires if not properly contained. Fire is the highest risk of loss in cotton bales and cotton warehouses, and these fires have caused problems in the cotton industry for over 100 years. In recent years those in the cotton industry have lost substantial amounts of money from cotton bales combusting.
Cotton fires burn hot and fast, and can at times take an entire warehouse with them if not contained quickly. Even when the fire department is called immediately, it can take 15 minutes or longer for a truck to get out to the warehouse, and by that time the damage is already severe. Often times, even after the fire truck arrives, the fire department struggles to contain the fire safely. Temperatures can rise to the point of melting the concrete in the warehouse, causing not only a loss of all cotton inside the warehouse but the warehouse building and foundation as well. For the foregoing reasons, there is a need to for a fire suppression system to put out and contain the fire quickly before the fire has a chance to spread. It is to such a fire suppression system that the present disclosure is directed.
The problem of quickly suppressing fires in large industrial warehouses is solved by a mobile fire suppression system described herein. The mobile fire suppression system may comprise a pump, a substance release tube (SRT), a first tank, a second tank, and a recirculation valve assembly (RVA). The pump comprises a pump housing defining a suction inlet and a discharge outlet. The SRT comprises a substance inlet and a substance release outlet. The first tank receives a foaming agent and has a first cavity, a first inlet, and a first outlet. The second tank receives the foaming agent and a carrier agent. The second tank comprises a second cavity, a second inlet, and a second outlet, the first outlet being in selective fluid communication with the second cavity. The RVA comprises a recirculation inlet fluidly connected to the discharge outlet of the pump, a release outlet fluidly connected to the substance inlet of the substance release tube, and a recirculation outlet in fluid communication with the second cavity. The RVA is operable to selectively direct a flow from the recirculation inlet to one of the release outlet and the recirculation outlet.

Not every component may be labeled in every drawing. Like reference numerals in the figures may represent and refer to the same or similar element or function. In the drawings:
The following detailed description of example embodiments refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
Before explaining at least one embodiment of the disclosure in detail, it is to be understood that the disclosure is not limited in its application to the details of construction, experiments, exemplary data, and/or the arrangement of the components set forth in the following description or illustrated in the drawings unless otherwise noted.
The disclosure is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for purposes of description and should not be regarded as limiting.
As used in the description herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” or any other variations thereof, are intended to cover a non-exclusive inclusion. For example, unless otherwise noted, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may also include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Further, unless expressly stated to the contrary, “or” refers to an inclusive and not to an exclusive “or”. For example, a condition A or B is satisfied by one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
In addition, use of the “a” or “an” are employed to describe elements and components of the embodiments herein. This is done merely for convenience and to give a general sense of the inventive concept. This description should be read to include one or more, and the singular also includes the plural unless it is obvious that it is meant otherwise. Further, use of the term “plurality” is meant to convey “more than one” unless expressly stated to the contrary.
As used herein, qualifiers like “substantially,” “about,” “approximately,” and combinations and variations thereof, are intended to include not only the exact amount or value that they qualify, but also some slight deviations therefrom, which may be due to computing tolerances, computing error, manufacturing tolerances, measurement error, wear and tear, stresses exerted on various parts, and combinations thereof, for example.
As used herein, any reference to “one embodiment,” “an embodiment,” “some embodiments,” “one example,” “for example,” or “an example” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment and may be used in conjunction with other embodiments. The appearance of the phrase “in some embodiments” or “one example” in various places in the specification is not necessarily all referring to the same embodiment, for example.
The use of ordinal number terminology (i.e., “first”, “second”, “third”, “fourth”, etc.) is solely for the purpose of differentiating between two or more items and, unless explicitly stated otherwise, is not meant to imply any sequence or order of importance to one item over another.
The use of the term “at least one” or “one or more” will be understood to include one as well as any quantity more than one. In addition, the use of the phrase “at least one of X, Y, and Z” will be understood to include X alone, Y alone, and Z alone, as well as any combination of X, Y, and Z.
Where a range of numerical values is recited or established herein, the range includes the endpoints thereof and all the individual integers and fractions within the range, and also includes each of the narrower ranges therein formed by all the various possible combinations of those endpoints and internal integers and fractions to form subgroups of the larger group of values within the stated range to the same extent as if each of those narrower ranges was explicitly recited. Where a range of numerical values is stated herein as being greater than a stated value, the range is nevertheless finite and is bounded on its upper end by a value that is operable within the context of the invention as described herein. Where a range of numerical values is stated herein as being less than a stated value, the range is nevertheless bounded on its lower end by a non-zero value.
When values are expressed as approximations, e.g., by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. Reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. The term “about” when used in reference to numerical ranges, cutoffs, or specific values is used to indicate that the recited values may vary by up to as much as 10% from the listed value. Thus, the term “about” is used to encompass variations of ±10% or less, variations of ±5% or less, variations of ±1% or less, variations of ±0.5% or less, or variations of ±0.1% or less from the specified value.

In conclusion, the fire suppression system 10 and the exemplary method 600 of using the fire suppression system 10 have been described. The fire suppression system 10 can be placed at a site where a risk of fire exists, such as a warehouse for storing products having at least one industrial machine onsite. Exemplary products include, but are not limited to agricultural products, such as cotton bales, hay bales, wood, and the like; industrial products such as chemicals; and/or consumer products such as textiles. When a fire is started through spontaneous combustion, equipment failure, or a natural weather event, for example, the industrial machine can be engaged to lift and transport the fire suppression system 10 to the location of the fire so that the fire suppression system 10 can be used to quickly contain the fire at its beginning phase to put the fire out. Simultaneously, other industrial machines can be used to move other products away from the site of the fire while the fire is being contained to reduce the risk of the fire spreading.
With respect to cotton, fire is the number one risk of disastrous loss in cotton bales and cotton warehouse buildings. The engagement points 118b on the sides of the support frame 110 may be configured to be used with conventional cotton bale clamps connected to a forklift. This permits the forklifts within warehouses storing cotton bales to quickly lift and transport the fire suppression system 10 to apply the foam solution to put out and/or contain a fire. It is respectfully submitted that the disclosed fire suppression system 10 solves a long-felt but unsolved need in the cotton industry to assist in quickly containing and putting out a fire without incurring a disastrous loss in cotton bales and cotton warehouse buildings.
