Sewage filtering and recycling device convenient to use

The invention discloses a convenient-to-use sewage filtering and recycling device, and the device comprises a mounting pipe; a water inlet pipe and a water outlet pipe are mounted on the mounting pipe; a sealing top cover is detachably mounted at the top end of the mounting pipe, a plurality of fixing rods are uniformly and fixedly mounted on the bottom wall of the sealing top cover, and a mounting frame is jointly and fixedly mounted at the bottom ends of the fixing rods; a metal filter screen is fixedly mounted on the inner side wall of the mounting frame, the water inlet pipe and the water outlet pipe are located at the bottom end and the top end of the metal filter screen respectively, an air cylinder is fixedly mounted on the top wall of the sealing top cover, and a piston rod is fixedly mounted at the output end of the air cylinder. Sewage is pumped into a mounting pipe, filtered impurities can be accumulated at the bottom end of a metal filter screen, an air cylinder is started to drive a piston rod to drive a mounting plate, and after a mounting rod and a conical blocking block move downwards, the impurities accumulated at the bottom end of the metal filter screen can be discharged from the bottom end of the mounting pipe; therefore, substances such as filtered residues can be conveniently cleaned or recycled, the design is reasonable, and the practical effect is good.
