[0002] There are many sources of sewage, including domestic sewage and factory sewage. These sewage cannot be discharged directly and usually need to be filtered by sewage treatment equipment before they can be discharged normally. Before filtering by sewage treatment equipment, sewage is often pre-treated (physical filtration, such as filtering plastic bag fragments, leaves, particulate matter, etc.).

[0003] Sewage is transported through pipes. There are currently two pre-treatment methods. One is to install the filter component directly in the pipe. Due to the small inner diameter of the pipe, the filter surface is small, and frequent replacement is required, which is inconvenient. The other is to install it in a box. The pipe is fixedly connected to the box. The box is large, and the filter surface is increased. However, the filter plastic bag fragments and leaves remain in the box, making it inconvenient to clean and replace the filter component. Utility Model Content

A water inlet joint 30 and a water outlet joint 40 are welded to the front and back of the box body 10, respectively. The water inlet joint 30 is connected to the water inlet pipe, and the water outlet joint 40 is connected to the water outlet pipe. An elastic locking mechanism 50 is installed at the bottom end of the box body 10, and two groups of support pipes 60 are welded to the top surface of the box body 10, each supporting pipe 60 is welded to the top surface of the box body 10, and each supporting pipe 60 is welded to the top surface of the box body 10. The tubes 60 are all sleeved with sealing rings 70 to play a sealing role. The sealing rings 70 are welded to the support tubes 60. Each group of support tubes 60 is inserted with a shell 80. The bottom surface of the shell 80 fits on the top surface of the sealing ring 70. The interiors of the front and rear shells 80 are both provided with sealing frames 90 welded to the inner walls thereof to limit the grille 100 from continuing to move into the shell 80 and play a blocking role. The front and rear shells 80 are both clamped with grilles 100 that match them, and a filter screen 110 is sandwiched between the two grilles 100 to play a good filtering role.

[0022] Specifically, a plurality of clamping columns 120 are integrally connected to the back of the front housing 80 , and a plurality of circular clamping grooves 130 are provided on the front of the rear housing 80 , and the clamping columns 120 are clamped in the circular clamping grooves 130 .

[0023] In this embodiment, the two shells 80 can be connected by snapping, which is convenient for the subsequent assembly and disassembly of the combined shells 80 .

[0024] Specifically, a plurality of circular openings 140 are formed on the bottom surface of the housing 80 , and the diameter of the circular openings 140 is equal to the outer diameter of the support tube 60 .

[0025] In this embodiment, the support tube 60 passes through the circular opening 140 so that the combined shell 80 can only move up and down.

[0026] Specifically, arc-shaped insert tubes 150 are inserted into both sides of the shell 80, and the arc-shaped insert tubes 150 are welded and fixedly connected to the shell 80. The elastic locking mechanism 50 includes a lifting plate 51, and the top surface of the lifting plate 51 is welded with two springs 52 welded to the bottom surface of the box body 10.

[0029] In this embodiment, the entire grid structure is fixed and installed, and effective space is provided for the operation and installation of the elastic locking mechanism 50 .

[0030] The working principle and use process of the utility model are as follows: water enters the front cavity of the box body 10 through the water inlet joint 30, and then enters the cavity of the front shell body 80 through the support pipe 60. Under the filtration of the front grille 100, larger impurities can be filtered in the front shell body 80, and then the sewage enters the rear shell body 80 through the filtration of the filter net 110, and then enters the rear cavity of the box body 10 from the rear support pipe 60, and finally discharged from the water outlet joint 40.
