the surface of the parallel connection pipe (1) is provided with an intervention part (227) matched with the sealing cover (223);
when in use, the working process is as follows:
s1, when the sewage filter is used, the sewage filter is directly connected with a sewage pipeline through a flange plate, so that sewage enters from an inlet end (3) of a parallel connection pipe (1) and is led out from an outlet end (4), and the sewage can be filtered by a ball filter mechanism (2) in the process;
s2, the upper end and the lower end of a cross pore canal formed by two channels (212) on the sphere (211) are normally sealed by a sealing cover (223), sewage in the fixed-connection pipe (1) flows through a transverse path formed by the channels (212), solid filtering is carried out by the filter plate (213) at the port, under continuous filtering, the filter plate (213) at one side of the inlet end (3) is gradually blocked and deposited, the pressure at the inlet end (3) is increased due to unsmooth water flow, the water flow pushes the ball body (211) to move along the sliding port (214) and the compression spring sheet (218) by using the end shaft (216) and the sliding seat (215), so that the bayonet (2110) is separated from the bayonet (219), and the clamping of the end shaft (216) is released, at the moment, the ball body (211) is pushed by water flow to deflect along the sliding seat (215) by using the end shaft (216), the channel (212) which is blocked transversely is switched with the vertical channel (212), and the new channel (212) and the filter plate (213) are used for filtering, and in the process, the cover (223) inside the sphere (211) keeps moving synchronously with the sphere (211) along the sliding seat (215) through the bracket (222) and the shaft lever (221), meanwhile, deflection cannot occur, the upper and lower side channels (212) after transposition are ensured to be closed to avoid interference, therefore, when the filter is blocked, the automatic switching of the filter components in the connection pipe (1) is realized by using pipe pressure;
s3, because the steel sheet (2112) restricts the shaft (216) in a single direction, the filter plate (213) facing the blocking surface on the ball body (211) can only deflect downwards, the surface of a sealing cover (223) of the lower blocking channel (212) is provided with an elastic membrane (225), after the switching of the filtering channel (212) is completed, the elastic membrane (225) is expanded outwards by positive pressure in the sewage pipeline, so that the elastic membrane (225) is popped out and contacts the filter plate (213) in the lower blocking state, the vibration is formed on the filter plate (213), most impurities on the surface of the filter plate are shaken in a lower lateral pipe opening (2271), meanwhile, the bulge (226) on the surface of the elastic membrane (225) can be abutted into a hole in the filter plate (213) to extrude the blockage, the cleaning effect on the filter plate (213) is further improved, and the cleaning process is automatic operation realized by switching of the pipe pressure and the filter component.
2. The novel environment-friendly sewage filter based on self-cleaning function as claimed in claim 1, wherein: intervene portion (227) including set up branch pipe mouth (2271) in taking over and taking over (1) both sides about the surface, two branch pipe mouth (2271) correspond with upper and lower both sides filter plate (213) respectively, and two branch pipe mouths (2271) seal through threaded connection pipe lid (2272).
3. The novel environment-friendly sewage filter based on self-cleaning function as claimed in claim 1, wherein: the filter plate (213) is fixed in the port of the channel (212) by a screw.
4. The novel environment-friendly sewage filter based on self-cleaning function as claimed in claim 1, wherein: and the surface of the sealing cover (223) is fixedly provided with an adhesive surface which is attached to the opening edge of the channel (212) in an auxiliary manner.
