Description

Technical Field

[0001] This utility model relates to the field of foam fire extinguishing agent production technology, and in particular to a foam fire extinguishing agent raw material pretreatment device. Background Technology

[0002] Foam extinguishing agents are effective extinguishing agents for flammable and combustible liquids. They primarily work by creating a coagulated foam layer on the liquid surface, which suffocates and cools the liquid. They are water-miscible agents that extinguish fires by producing foam through mechanical action or chemical reaction. Foam extinguishing agents generally consist of foaming agents, foam stabilizers, viscosity reducers, antifreeze agents, solubilizers, preservatives, and water. They are mainly used to extinguish fires involving non-water-soluble flammable liquids and general solids. Specialized foam extinguishing agents can also extinguish fires involving water-soluble flammable liquids. Foam extinguishing agents are classified into chemical foam, air foam, fluoroprotein foam, aqueous film-forming foam, and alcohol-resistant foam, among others.

[0003] To ensure production efficiency and quality, raw materials need to be pre-treated. However, most equipment has a relatively simple function or lacks effective switching methods between different processing stages, which can easily affect each other and hinder related work.

[0020] The following description, in conjunction with the accompanying drawings, describes a foam fire extinguishing agent raw material pretreatment device according to an embodiment of the present invention.

[0021] like Figures 1 to 3 As shown in the figure, a foam fire extinguishing agent raw material pretreatment device according to an embodiment of the present invention may include a heating chamber 1, a filtering chamber 2, a linkage component 3 and a stirring component 4.

[0022] The heating chamber 1 and the filtering chamber 2 are connected. The heating chamber 1 includes an inner layer 11, a sandwich layer 12 and an outer layer 13. A heating coil 14 is provided in the sandwich layer 12.

[0023] It should be noted that the heating coil 14 can heat the heating chamber 1 evenly, which facilitates subsequent work.

[0024] A filter screen 21 is provided in the filter chamber 2, and the cleaning rod 45 abuts against the filter screen 21.

[0025] It should be noted that filter screen 21 can filter impurities in the raw materials.

[0026] The linkage component 3 includes a butterfly valve 31, a rotating rod 32, a turntable 33, a gear 34, a placement frame 35, a connecting block 36, a rack 37, and a telescopic rod 38.

[0027] Among them, the butterfly valve 31 is rotatably installed in the middle, the rotating rod 32 is connected to the butterfly valve 31, the turntable 33 is located on the outside and is connected to the rotating rod 32, the gear 34 is sleeved on the rotating rod 32, the placement frame 35 is located between the heating chamber 1 and the filter chamber 2, the connecting block 36 is fixedly installed on the placement frame 35, the rack 37 is installed on the connecting block 36 and meshes with the gear 34, and the telescopic rod 38 is installed at the bottom of the placement frame 35.

[0028] It should be noted that the linkage component 3 can adjust the position of the stirring component 4 while controlling the filter, thereby achieving stirring during filtration, increasing the filtration speed, and cleaning the filter screen 21 during heating.

[0029] The stirring assembly 4 includes a drive motor 41, a transmission structure 42, a stirring shaft 43, a stirring rod 44, and a cleaning rod 45.

[0030] The drive motor 41 is positioned above the placement frame 35, and the transmission structure 42 is located within the placement frame 35.

[0031] The transmission structure 42 includes a driving pulley 421, a driven pulley 422, and a transmission belt 423.

[0032] The driving wheel 421 is connected to the output end of the drive motor 41, the driven wheel 422 is connected to the stirring shaft 43, and the transmission belt 423 is sleeved on the driving wheel 421 and the driven wheel 422.

[0033] It should be noted that the stirring component 4 can stir the materials, speed up the efficiency of each step, and facilitate related work.

[0034] The stirring shaft 43 is connected to the output end of the transmission structure 42, the stirring rod 44 is mounted on the stirring shaft 43, and the cleaning rod 45 is located at the bottom of the stirring shaft 43.

[0035] It should be noted that the cleaning rod 45 is triangular in shape, which makes it easy to scrape off the filter screen 21 and ensures the cleaning effect.

[0036] Specifically, when relevant personnel need to process the raw materials of foam extinguishing agent, the raw materials are first placed in the heating chamber 1. The temperature of the heating chamber 1 is increased by the heating coil 14 to heat the raw materials. After heating, the turntable 33 can be rotated. The turntable 33 will drive the butterfly valve 31 through the rotating rod 32 to open the conveying pipe. The heated material will flow from the heating chamber 1 through the conveying pipe into the filter chamber 2.

[0037] Next, the drive motor 41 is started, which drives the drive wheel 421 to rotate. The drive wheel 421 will continue to drive the driven wheel 422 to rotate through the transmission belt 423. When the driven wheel 422 rotates, it will continue to drive the stirring shaft 43 to rotate. The stirring shaft 43 will continue to drive the stirring rod 44 and the cleaning rod 45, thereby stirring the material and accelerating the filtration speed.

[0038] After the filtration is completed, the turntable 33 is rotated again to close the delivery pipe, and the heating chamber 1 can start the next round of heating. When the turntable 33 rotates, it drives the gear 34 through the rotating rod 32. When the gear 34 rotates, it drives the rack 37 that meshes with it. The rack 37 continues to drive the placement frame 35 to move through the connecting block 36. When the placement frame 35 moves, it will continue to drive the stirring component 4 and make the cleaning rod 45 come into contact with the filter screen 21. At this time, the drive motor 41 is started, and the drive motor 41 will drive the cleaning rod 45 to clean the filter screen 21.

[0039] In summary, the foam extinguishing agent raw material pretreatment device according to the present invention can achieve heating and filtration of the raw material through the heating chamber and the filtration chamber respectively, ensuring the integrity of the raw material treatment process.
