[0030] The cleaning assembly 4 includes a fixed housing 41, inside which a motor 42 is housed. The output shaft of the motor 42 is fixedly connected to a first sprocket 44. A chain 45 is located on one side of the first sprocket 44, and a second sprocket 46 is located at one end of the chain 45. A circular hole is provided at the top of the fixed housing 41, and lubricating cotton 43 is fixedly connected to the circular hole. The output shaft of the motor 42 passes through the lubricating cotton 43. A scraper 47 is fixedly connected to the inner wall of the second sprocket 46. A fixed plate 48 is fixedly connected to the bottom end of the scraper 47. A connecting rod 49 is fixedly connected to the bottom surface of the fixed plate 48, and a pulverizing blade 410 is fixedly connected to the bottom end of the connecting rod 49. The bottom end of the concentration tank 1 is fixedly connected to... The system includes a conveying funnel 6, with a discharge pipe 411 fixedly connected to its bottom end. A scale ion detector 412 is fixedly connected to the inner wall of the conveying funnel 6. One side of the fixing frame 2 is fixedly connected to the side wall of the fixing shell 41. The bottom end of the discharge pipe 411 is rotatably connected to the inner wall of the second sprocket 46. The top end of the concentration tank 1 is fixedly connected to a feed pipe 3. The bottom end of the second sprocket 46 is rotatably connected to a conveying pipe 8. A connecting plate 7 is fixedly connected to the side wall of the conveying pipe 8. The connecting plate 7 is fixedly connected to the side wall of the fixing frame 2. A scraper 47 is located inside the discharge pipe 411. The scraper 47 cleans the scale in the inner wall of the discharge pipe 411, scraping off the scale to prevent excessive scale accumulation from clogging the discharge pipe 411.

[0031] During operation, the scaling degree is detected by the scaling ion detector 412, which triggers the motor 42. The motor 42 drives the first sprocket 44, which in turn drives the chain 45, which in turn drives the second sprocket 46. The second sprocket 46 then drives the scraper 47, which cleans the scaling in the inner wall of the discharge pipe 411, removing the scale to prevent excessive accumulation and blockage. The scraped-off scale then drives the fixed plate 48, which in turn drives the connecting rod 49. The connecting rod 49 drives the crushing blade 410, which crushes the scale to prevent it from becoming too large and facilitates its discharge. While the motor 42 is running, the output shaft of the motor 42 is lubricated by the lubricating cotton 43 for easy maintenance.

Then, the fixing plug 54 squeezes any remaining lubricating oil from the inner wall of the oil inlet pipe 55 into the lubricating cotton 43 to avoid waste.

[0034] When using the lubricating cotton 43, when it is necessary to add lubricating oil, pull the fixing cover 51. The fixing cover 51 drives the fixing block 52, and the fixing block 52 drives the fixing magnetic block 53, so that the fixing magnetic block 53 separates from the snap-fit ​​groove 57. Then, lubricating oil is poured into the lubricating cotton 43 through the oil inlet pipe 55 to replenish it. After replenishment, the fixing plug 54 is inserted into the oil inlet pipe 55 to squeeze the remaining lubricating oil in the oil inlet pipe 55 into the lubricating cotton 43 to avoid waste.
