At the same time, the first moving device 4 drives the first push plate 13 to move back and forth at the bottom of the purification tank 1, and pushes the silt into the temporary storage tanks 11 on both sides, and then the second moving device 5 drives the second push plate 14 to move back and forth in the temporary storage tank 11, and pushes the silt in the temporary storage tank 11 into the silt discharge shells 2 on both sides, completing the cleaning of the silt in the entire purification tank 1, and eliminating the need for staff to manually clean the silt in the purification tank 1, saving time and thus improving the efficiency of silt cleaning.

[0054] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
