Further, as shown in fig. 9:
one end of each of the first insertion rod 7b and the second insertion rod 7c extending to the outer side of the second chamber 3 is provided with a cylinder 7b2 with a diameter larger than that of the socket 3d, the end of the cylinder 7b2 is further provided with a disc 7b3 with a diameter larger than that of the cylinder 7b2, the elastic element 7d is specifically a compression spring 7d1, the compression spring 7d1 is sleeved on the cylinder 7b2, and two ends of the compression spring 7d1 are respectively fixed on the surface of the disc 7b3 and the outer side wall of the second chamber 3.
Based on the above-mentioned embodiment, the connection of the compression springs 7d1 between the first and second insertion rods 7b and 7c and the second chamber 3 enables the first and second insertion rods 7b and 7c to move within the insertion openings 3d, thereby effectively achieving the cooperation between the support plate 7a and the first and second insertion rods 7b and 7 c.
Further, as shown in fig. 9:
a protective shell 7e is sleeved outside each disk 7b3, and a vent 7e1 coaxial with the disk 7b3 is further arranged on the protective shell 7e at the position of the second inserting rod 7 c.
Based on the above embodiment, when the first filter plate 4 switches the second filter plate 5, the air vent 7e1 is filled with air, the disk 7b3 on the second plunger 7c pushes the support plate 7a back to the original position after receiving air pressure, so that the rotating plate 6b1 can rotate back, and when the rotating plate 6b1 leaves the first plunger 7b, the air vent 7e1 stops ventilation, and the second plunger 7c returns to the original position.
This application has realized the filtration to sewage promptly through the drive of coupling mechanism 6a to the connection of first filter plate 4 and second filter plate 5 and conversion mechanism 6b to first filter plate 4, has also accomplished the switching under the sewage purification flow of first filter plate 4 and second filter plate 5 not influencing, has improved the filterable efficiency of sewage.
