The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0024] The following description, in conjunction with the accompanying drawings, describes a mixing device for producing foam fire extinguishing agents that is easy to clean.

[0030] Two support frames 21 are respectively mounted on the base plate 1, two second drive motors 22 are respectively mounted on opposite sides of the two support frames 21 through mounting brackets, and two load-bearing rods 23 are respectively axially mounted on opposite sides of the two support frames 21.

[0033] The stirring structure 44 includes: a semi-mounting ring 441 and a semi-stirring rod 442.
[0034] Multiple semi-mounting rings 441 are respectively engaged from top to bottom on opposite sides of the guide rod 43, and each pair of adjacent semi-mounting rings 441 are fixed to the guide rod 43 by locking parts. Each semi-stirring rod 442 is provided on the opposite end of each semi-mounting ring 441, and each pair of adjacent semi-stirring rods 442 are respectively attached to each other. Each of the semi-stirring rods 442 at the end away from the semi-mounting ring 441 has a placement hole 4421, and the placement hole 4421 penetrates the upper surface of the semi-stirring rod 442. Limiting holes 4422 are respectively provided on the opposite side of the placement hole 4421, and each of the semi-stirring rods 442 penetrates the semi-stirring rod 442.
[0035] The mounting structure 45 includes: a mounting rod 451, a first mounting plate 452, a first spring 453, and a limiting rod 454.
[0036] The mounting rod 451 is movable within the storage hole 4421, and storage slots 4511 are respectively opened on the opposite sides of the mounting rod 451. A threaded hole 4512 is opened on the mounting rod 451 at the end away from the semi-mounting ring 441. The first mounting plate 452, the first spring 453 and the limiting rod 454 are connected in sequence and are set in the storage slot 4511 through the first mounting plate 452, and the limiting rod 454 is located in the limiting hole 4422.
[0037] The wall scraping structure 46 includes: a threaded rod 461, a connecting rod 462, and a scraper 463.
[0038] Among them, the threaded rod 461, the connecting rod 462 and the scraper 463 are connected in sequence and are threaded into the threaded hole 4512 through the threaded rod 461, and the scraper 463 abuts against the inner wall of the mixing tank 3.
[0039] In another possible embodiment of the present invention, the scraper 463 is made of rubber, which effectively reduces the degree of damage caused by the scraper 463 to the inner wall of the mixing tank 3.
[0040] The limiting structure 47 includes: a second mounting plate 471, a slide rod 472, a pull plate 473, a limiting block 474, and a second spring 475.
[0041] Among them, a second mounting plate 471 is provided on a plurality of half stirring rods 442 away from the half mounting ring 441, and each second mounting plate 471 is provided with a sliding hole 4711. Each sliding rod 472 slides in each sliding hole 4711. A pull plate 473 and a limiting block 474 are provided on the opposite end and the opposite end of each sliding rod 472, and the limiting block 474 is in contact with the top of the connecting rod 462. A second spring 475 is sleeved on each sliding rod 472, and the two ends of the plurality of second springs 475 are connected to the plurality of second mounting plates 471 and the plurality of pull plates 473, respectively.
[0042] It should be noted that by setting the limiting structure 47, the wall scraping structure 46 is prevented from rotating or shaking on its own, which would reduce the cleaning effect of the wall scraping.
[0043] Specifically, when this utility model is transported to the work area, and the inner wall of the mixing tank 3 needs to be cleaned after use, firstly, the first drive motor 42 is turned on, thereby driving multiple scrapers 463 to rotate, thereby scraping off the viscous liquid on the inner wall of the mixing tank 3. Secondly, the second drive motor 22 is turned on, causing it to drive the mixing tank 3 to rotate, thereby causing the scraped viscous liquid to slide out along the inner wall of the mixing tank 3.
[0044] It should be noted that when the first drive motor 42 is working, the drive end of the first drive motor 42 drives the guide rod 43 to rotate, which in turn drives multiple stirring structures 44, multiple mounting structures 45, multiple wall scraping structures 46 and multiple limiting structures 47 to rotate in sequence, thereby scraping the viscous liquid on the inner wall of the mixing tank 3 through multiple scrapers 463.
[0045] When the scraper 463 needs to be removed, firstly, press the limiting rod 454 on the mounting rod 451 to compress it. Simultaneously, the first spring 453 deforms under pressure. Next, move the scraper 463 to one side of the semi-mounting ring 441. At this time, the limiting rod 454 continues to be compressed and slides along the inner wall of the semi-stirring rod 442. Simultaneously, the first spring 453 continues to be compressed. Once it reaches the appropriate position, release the limiting rod 454. At this point, due to the natural return of the first spring 453... The elastic potential energy drives the limiting rod 454 to move and be limited within the limiting hole 4422. Then, the scraper 463 is rotated upward, which in turn drives the connecting rod 462, the threaded rod 461 and the mounting rod 451 to rotate in sequence. At the same time, during the rotation, the connecting rod 462 passes through the two limiting blocks 474. When it is rotated to a suitable angle, the connecting rod 462 is rotated, which in turn drives the threaded rod 461 to rotate and disengage from the mounting rod 451. At this time, the scraper structure 46 can be removed and cleaned.
[0046] In summary, the foam extinguishing agent production mixing device according to the present invention, which is easy to clean, facilitates the scraping of the viscous liquid on the inner wall of the mixing tank 3 by setting the cooperation between the installation structure 45 and the wall scraping structure 46. When the viscosity of the viscous liquid is high, it can be cleaned better. On the other hand, it is easy to adjust the distance between the scraper 463 and the guide rod 43 to adapt to different inner wall sizes of the mixing tank 3. It is also simple to operate and highly practical.
