Description

Technical Field

[0001] This utility model relates to the field of submersible sewage pump technology, and in particular to a filter structure for a submersible sewage pump. Background Technology

[0002] Submersible pumps are essential equipment for deep well water extraction. During operation, the entire unit is submerged in water to extract groundwater to the surface. They are used for domestic water supply, mine rescue operations, industrial cooling, farmland irrigation, seawater lifting, ship ballast adjustment, and even for fountain landscaping.

[0003] A search revealed a public disclosure (announcement) number: CN210106267U, which discloses a filter structure for a submersible sewage pump. The structure includes a water pump, a base, and an outlet pipe on the side wall of the pump. A drain pipe is connected to the end of the outlet pipe away from the pump. A primary filter is located on the side of the base away from the pump, and a secondary filter is located between the outlet pipe and the outlet pipe. The advantages are: This invention installs a first filter screen between the base and the mounting ring, and a filter plate is installed at the bottom of the mounting ring, providing coarse filtration of the water entering the submersible pump. This prevents larger objects from entering the pump, protecting it and extending its service life. The sewage pipe between the outlet pipe and the drain pipe provides secondary filtration of the water discharged from the submersible pump, ensuring more stable drainage. Both the filter plate and the second filter screen are removable, facilitating cleaning and maintenance and ensuring effective filtration.

[0004] In the aforementioned existing technical solutions, the filter structure is disassembled and installed using bolts and nuts. This connection method requires the removal of multiple bolts when disassembly is needed, making disassembly cumbersome and wasting a lot of time.

[0005] Therefore, we propose a filter structure for submersible sewage pumps. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide a filter structure for a submersible sewage pump.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a filter structure for a submersible sewage pump, including a sewage pump, a drain pipe, and a mounting base. The bottom of the mounting base is provided with a second filter frame and a first filter frame. Fixing blocks are fixed on both sides of the mounting base. Positioning holes and insertion cavities are respectively opened on both sides and the bottom of the fixing blocks. Insert rods are fixed on both sides of the first filter frame. Positioning holes are opened on both sides of the insert rods. Mounting frames are fixed on the side walls of the fixing blocks. Through holes and limiting grooves are respectively opened on both sides of the mounting frames. A pull rod slides in the through hole. Pull rings and limiting plates are fixed at both ends of the pull rod. A return spring is sleeved on the pull rod. A limiting rod passes through the limiting groove.

[0008] Preferably, the second filter frame has connecting grooves at all four ends, and the first filter frame has connecting rods fixedly connected to all four ends at the top.

[0009] Preferably, handles are fixedly connected to the center of the front and rear side walls of the first and second filter frames, and the pore size of the filter screen of the first filter frame is larger than that of the filter screen of the second filter frame.

[0010] Preferably, the limiting groove, the limiting rod, the first positioning hole, and the second positioning hole are all cross-shaped structures and are compatible with each other.

[0011] Preferably, a limiting plate is fixedly connected to one end of the pull rod located in the inner cavity of the mounting frame, and the upper and lower walls of the limiting plate are in contact with the upper and lower walls of the inner cavity of the mounting frame.

[0012] Preferably, the insert rod has an L-shaped structure, and the first filter frame is attached to the bottom of the second filter frame.

[0013] This utility model provides a filter structure for a submersible sewage pump. It has the following beneficial effects:

[0014] 1.

Each mounting frame 4 has a through hole 401 on its side wall away from the positioning hole 301. A pull rod 402, adapted to the through hole 401, is slidably mounted inside each through hole 401. A pull ring 403 is fixedly connected to one end of each pull rod 402 located outside the mounting frame 4.
