The sewage pipe is fixedly installed at the bottom of the second plate. The fixed end of the telescopic column is fixed at the bottom of the second plate. When the rotating rod rotates, it will drive the fan-shaped plate to rotate. When the rotating rod rotates, it will drive the third plate to rotate. When the sewage at the bottom is full, it will push the third plate upward to squeeze the telescopic column.

[0008] According to the above technical solution, the long plate contacts the triangular column, and the long rod contacts the pushing column. When the long plate moves, it will push the triangular column to move. When the triangular column moves, it will drive the second sliding plate to move in the second chute of the second plate.

[0011] According to the above technical solution, the scraping block contacts the sieve plate, and the convex block contacts the contact plate. When the scraping block moves, it will remove the dirt on the sieve plate and at the same time discharge the dirt into the telescopic tank below.

[0012] According to the above technical solution, the soft plate contacts the semi-cylinder, and the rotating blade contacts the tooth groove of the gear. When the soft plate moves, it will contact the semi-cylinder, causing the semi-cylinder to vibrate, thereby vibrating the sieve plate.

The double-sided inclined rod is slidably installed at the bottom of the inlet plate. The bottom block is fixedly installed on the inner wall of the square frame. When the telescopic square plate of the water outlet pipe moves downward, it will push the inlet plate downward. When the inlet plate moves downward, it will drive the triangular stopper to move. When the triangular stopper moves, it will be squeezed against the bottom block.

[0014] According to the above technical solution, the inclined plane block contacts the triangular stopper, and the double-sided inclined rod contacts the triangular stopper. When the double-sided inclined rod moves, it will drive the triangular stopper to move to block the inlet plate.

[0015] The present invention provides a sewage purification and filtration device for preventing water environmental pollution. It has the following beneficial effects:

[0016] (1) In this invention, when the rotating rod rotates, it will drive the fan plate to rotate. When the fan plate rotates, it will remix the sediment and the medicament at the bottom, and react with the sewage again. When the triangular column moves, it will drive the second slide plate to move in the second chute of the second plate. When the second slide plate moves, it will block the outlet of the sewage pipe, so that the sewage above can enter the lower part intermittently, avoiding the backflow of the medicament below to the upper part, causing waste of the medicament, and at the same time, it can avoid the influence of excessive water flow on the sieve net at the back.

[0017] (2) In this invention, when the telescopic rod moves, it will drive the telescopic plate to move. When the telescopic plate moves, it will drive the scraping block to move downward, scraping the stains on the sieve plate. At the same time, it will scrape intermittently to prevent damage to the sieve plate. When the soft plate moves, it will contact the semi-cylinders on the sieve plate, generating vibration. When the contact plate moves, it will drive the connecting rod to move, vibrating the sieve net to more effectively clean the dirt on the sieve plate, and at the same time, it will indirectly open the cleaning port below.

[0018] (3) In this invention, when the cuboid moves, it drives the inclined plane block to move. When the inclined plane block moves, it pushes the triangular stopper to move, blocking the water inlet, and can effectively control the sewage above from entering the telescopic tank below. When the telescopic tank is pulled out from the chute plate, it drives the L-shaped slide bar to move. When the L-shaped slide bar moves, it drives the double-sided inclined bar to move. When the double-sided inclined bar moves, it drives the triangular stopper to move, which can effectively prevent the sewage inside from scattering when the telescopic tank is replaced, affecting the surrounding environment, and at the same time can avoid subsequent cleaning by the staff.
