[0032] Furthermore, the detachable fixing mechanism 2 includes a fixing ring 16, a limiting ring 19, two arc-shaped fixing plates 22, and two telescopic motors 17. The inner wall of the fixing ring 16 is provided with an internal thread. In use, the internal thread on the fixing ring 16 is threadedly connected to the external thread on the circular fixing plate 4. The lower end face of the fixing ring 16 has an annular groove 18, and the limiting ring 19 is provided in the annular groove 18. The two telescopic motors 17 are symmetrically arranged on the outer wall of the fixing ring 16. The limiting ring 19 has two symmetrical openings 20, and the two openings 20 are corresponding to the two telescopic motors 17. The output end of each telescopic motor 17 is fixedly connected to one end of the corresponding telescopic rod 21, and the other end of each telescopic rod 21 is fixedly connected to the corresponding arc-shaped fixing plate 22. The two arc-shaped fixing plates 22 are arranged opposite to each other, and each arc-shaped fixing plate 22 can freely pass through the corresponding opening 20 on the limiting ring 19.

[0033] Device assembly:

[0034] First, install the rotary motor 3 in the center of the upper end face of the circular fixing plate 4, ensuring that the output shaft of the rotary motor 3 passes vertically downward through the center hole of the circular fixing plate 4, and use fasteners (such as bolts, nuts, etc., not shown in the figure) to fix the rotary motor 3 to the circular fixing plate 4. Next, install the cleaning component 5 on the output shaft of the rotary motor 3. The rotating shaft 6 of the cleaning component 5 is fixedly connected to the output shaft of the rotary motor 3 through a coupling (not shown in the figure) or other suitable connection method.

[0035] Then, multiple cleaning units 7, multiple cleaning units 8, and multiple scraping units 9 are sequentially and alternately installed on the outer wall of the rotating shaft 6. Each cleaning unit 7 has a connecting plate 13 fixed to the rotating shaft 6 by welding or other suitable connection methods, and a water inlet 14 is provided on the connecting plate 13 for installing a heating column 15 and a heating wire. The arc-shaped scraper 10 is fixed to the outer wall of the connecting plate 13 by bolts or other fasteners.

[0036] Similarly, the connecting plate 2 of each cleaning unit 8 is also fixed to the rotating shaft 6 by welding or other connection methods, and multiple cleaning brushes 11 are evenly installed on the outer wall of the connecting plate 2. The connecting plate 3 of each scraping unit 9 is also fixed to the rotating shaft 6 in the same way, and a scraper 12 is installed on the outer wall of the connecting plate 3.

[0037] Next, assemble the detachable fixing mechanism 2. The inner wall of the fixing ring 16 is machined into an internal thread that matches the external thread of the circular fixing plate 4. The fixing ring 16 is then fitted onto the outer wall of the circular fixing plate 4, and the fixing ring 16 is rotated to connect it threadedly to the circular fixing plate 4. An annular groove 18 is formed on the lower end face of the fixing ring 16, and a limiting ring 19 is placed within the annular groove 18.

[0038] Then, two telescopic motors 17 are symmetrically installed on the outer wall of the fixed ring 16, ensuring that the output end of the telescopic motor 17 is fixedly connected to one end of the telescopic rod 21. Two openings 20 are symmetrically opened on the limiting ring 19, so that the two openings 20 correspond to the two telescopic motors 17. Two arc-shaped fixing plates 22 are fixed to the other end of the two telescopic rods 21 respectively, ensuring that the two arc-shaped fixing plates 22 can freely pass through the corresponding openings 20 on the limiting ring 19.

[0039] In use, first align the detachable fixing mechanism 2 of this device with the top opening (not shown in the figure) of the concrete mixing tank 23, and extend the lower end of the cleaning mechanism 1 into the mixing tank 23. Then, start the telescopic motor 17, so that the telescopic rod 21 drives the arc-shaped fixing plate 22 through the opening 20 on the limiting ring 19 and sticks tightly to the outer wall of the mixing tank 23 to achieve additional fixation of the cleaning mechanism 1.

[0040] Next, the rotating motor 3 is started, causing the rotating shaft 6 to drive the cleaning component 5 to rotate. Simultaneously, hot water is injected into the water inlet 14 of the cleaning unit 7 through an external water source (not shown in the figure), and the heating wire in the heating column 15 is activated to heat the hot water to prevent it from freezing in low-temperature environments. As the hot water flows through the arc-shaped scraper 10, it softens and washes away the stains on the inner wall of the mixing tank 23.

[0041] As the rotating shaft 6 rotates, the cleaning unit 7, the cleaning unit 8, and the scraping unit 9 sequentially clean, scrub, and scrape the inner wall of the mixing tank 23. The arc-shaped scraper 10 of the cleaning unit 7 can scrape away stubborn stains, the cleaning brush 11 of the cleaning unit 8 can scrub away looser stains, and the scraper 12 of the scraping unit 9 can further scrape away residual stains to ensure thorough cleaning.

[0042] During the cleaning process, the extension and retraction of the telescopic motor 17 can be adjusted as needed to change the pressure of the arc-shaped fixing plate 22 on the inner wall of the mixing tank 23, thereby adjusting the stability and cleaning effect of the cleaning mechanism 1. Simultaneously, the cleaning process can also be controlled by adjusting the rotation speed of the rotary motor 3 and the heating power of the heating column 15.

[0043] Device disassembly and maintenance:

[0044] After cleaning, first turn off the power to the rotating motor 3 and the heating column 15, and stop injecting hot water into the water inlet 14 of the cleaning unit 7. Then, start the telescopic motor 17, causing the telescopic rod 21 to drive the arc-shaped fixing plate 22 out of the opening 20 on the limiting ring 19, releasing the fixation on the mixing tank 23. Next, rotate the fixing ring 16 to separate it from the circular fixing plate 4, thereby removing the entire cleaning mechanism 1 from the mixing tank 23. Finally, remove the detachable fixing mechanism 2 from the mixing tank 23.

[0045] During disassembly, take care to protect all components of the cleaning mechanism 1 to avoid damage or loss. At the same time, regularly inspect and maintain all components of the cleaning mechanism 1, such as replacing worn cleaning brushes 11 and scrapers 12, to ensure long-term stable operation and effective cleaning.

[0046] The mixing tank cleaning device of this utility model can not only effectively deal with the problem of stain solidification in cold environments and improve cleaning efficiency and quality, but also has the advantages of flexibility, convenience and easy maintenance, and is suitable for cleaning operations of concrete mixing tanks of various sizes and types.
