[0030] Reference Figure 1-4 A filter tank assembly 9 is installed inside the upper end of the rear side of the body 1, and a plurality of lifting rings 21 are fixedly arranged on the top of the filter tank assembly 9, which is convenient for using lifting equipment to install the filter tank assembly 9 in the body 1 or to lift it out from the body 1. The filter tank assembly 9 includes a primary filter tank and a secondary filter tank, and the secondary filter tank is sleeved inside the primary filter tank. The multi-stage filtration is adopted to improve the filtering effect. The lower end of the water outlet of the filter tank assembly 9 is fixedly connected with a discharge pipe 17, and a pump body 14 is arranged on the lower side of the filter tank assembly 9. The water inlet of the pump body 14 is fixedly connected with a water inlet pipe 15, and the water outlet of the pump body 14 is fixedly connected with a water outlet pipe 16, and one end of the water outlet pipe 16 is connected with the water inlet of the filter tank assembly 9;
