[0029] According to a further optimization scheme, the bottom of the tank body 1 is funnel-shaped to prevent the chelating agent mixture from accumulating at the bottom of the tank body 1 .

[0030] In a further optimized solution, the transmission assembly includes a transmission rod 5 disposed in the tank body 1, the transmission rod 5 is fixedly connected to the first cleaning assembly and the second cleaning assembly, and one end of the transmission rod 5 extending out of the top surface of the tank body 1 is transmission-connected to the motor 4, and the motor 4 is fixedly connected to the top surface of the tank body 1. The motor 4 drives the transmission rod 5 to rotate, and the transmission rod 5 drives the first cleaning assembly and the second cleaning assembly to rotate.

[0031] A further optimized solution is that the first cleaning component includes a semicircular plate 6 that is slidably connected to the inner wall of the tank body 1, and a plurality of first movable rods 10 are fixedly connected to one end of the semicircular plate 6 that is away from the tank body 1. An end of the first movable rod 10 that is away from the semicircular plate 6 is slidably connected to a first sleeve 7, and an end of the first sleeve 7 that is away from the first movable rod 10 is fixedly connected to the transmission rod 5.

[0034] According to a further optimization scheme, the semicircular plate 6 is tilted so that the height of the highest end of the semicircular plate 6 at the bottom is higher than the height of the lowest end of the semicircular plate 6 at the top.

[0035] After the upper semicircular plate 6 scrapes the chelating agent mixture on the inner wall of the tank body 1 , the lower semicircular plate 6 can continue to scrape the chelating agent mixture and push it downward, so that the chelating agent mixture accumulates at the bottom of the tank body 1 .

[0036] A further optimized solution is that the second cleaning assembly includes a scraper 11 slidably connected to the inner wall of the tank body 1, the end of the scraper 11 facing away from the tank body 1 is fixedly connected to a second movable rod 15, the end of the second movable rod 15 away from the scraper 11 is slidably connected to a second sleeve 12, and the end of the second sleeve 12 away from the second movable rod 15 is fixedly connected to the transmission rod 5.
