[0018] The following description is only the preferred embodiment of the utility model, and does not limit the protection scope of the utility model.

[0019] A chemical circulating pump with filtering function, which comprises a pump body, a motor, a speed reducer, a pump shell, a filter cartridge, a flushing pipe and a rotating cap. Figures 1-4As shown, the system includes a base plate 1, a motor 2, a reducer 3, a housing 4, a pump housing 5, an impeller 6, a water outlet pipe 7, a water inlet pipe 8, a sewage discharge pipe 12, an automatic valve 13, and a filter cleaning assembly. The motor 2 is connected to the upper left side of the base plate 1, and the reducer 3 is connected to the upper middle part of the base plate 1. The output shaft of the motor 2 is connected to the input shaft of the reducer 3. The pump housing 5 is connected to the upper right side of the base plate 1, and the housing 4 is connected to the left side of the pump housing 5. A coupling is rotatably installed inside the housing 4. The left side of the coupling is connected to the output shaft of the reducer 3, and the right side of the coupling is connected to the impeller 6. The impeller 6 is located inside the pump housing 5. The upper part of the pump casing 5 is connected to the outlet pipe 7, and the right side of the pump casing 5 is connected to the inlet pipe 8. Both the outlet pipe 7 and the inlet pipe 8 are equipped with flanges for easy connection. The lower part of the inlet pipe 8 is connected to the drain pipe 12, and the lower part of the drain pipe 12 is equipped with an automatic valve 13. The inlet pipe 8 is equipped with a filter cleaning assembly, which includes a cap 9, a flushing pipe 10 and a filter cartridge 11. The upper part of the inlet pipe 8 is threadedly connected to the cap 9, which is provided with anti-slip texture for easy gripping. The middle of the cap 9 is connected to the flushing pipe 10, which has a conical structure at the bottom. The filter cartridge 11 is placed inside the inlet pipe 8.

[0020] When using this device, first place the base plate 1 in the area where the chemical circulating pump is used. Then, connect the external pipes through the flanges on the outlet pipe 7 and the inlet pipe 8. Next, start the motor 2, causing the output shaft of the motor 2 to rotate. The reducer 3 amplifies the output torque of the motor 2, and the reducer 3 drives the coupling on the housing 4 to rotate, causing the impeller 6 to rotate. This allows the liquid to enter the inlet pipe 8 through the external pipe, filter impurities in the liquid through the filter cartridge 11, and discharge the liquid from the outlet pipe 7 through the impeller 6. When it is necessary to clean the filter cartridge 11, an external water source can be connected through the flushing pipe 10 to allow water to flow through. The flushing pipe 10 sprays water onto the filter cartridge 11, and simultaneously opens the automatic valve 13, allowing wastewater and impurities to be discharged through the drain pipe 12. When the filter cartridge 11 needs to be replaced, the cap 9 can be rotated to open it by the action of the thread. Then, the filter cartridge 11 can be moved upward from the inlet pipe 8 and removed. The filter cartridge 11 to be replaced can then be placed in the inlet pipe 8. The cap 9 can then be aligned with the upper part of the inlet pipe 8, and the cap 9 can be rotated to close it by the action of the thread. This allows for easy cleaning and disassembly of the filter cartridge 11, facilitating its replacement. The operation is simple and convenient.

[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
