External gear transmission circulating water secondary filter screen

The invention belongs to the technical field of power plant circulating water filters, and particularly relates to an external gear transmission circulating water secondary filter screen. The differential pressure gauge is arranged and fixed outside the cylinder body, the net core frame is fixed inside the cylinder body, the net sheet is connected with the net core frame, and a shell of the main shaft is fixed on the net core frame; the gear motor is connected with the pinion through the coupler, and the pinion is meshed with the bull gear through teeth; the large gear is connected with one end of a main shaft, and the other end of the main shaft is connected with a sewage discharging hopper which is connected with a sewage discharging pipe. The reliability of the secondary filter screen is improved by strengthening the strength of the transmission mechanism and increasing the transmission torque, and the failure point of the speed reducer is eliminated. 本发明属于电厂循环水过滤器技术领域，具体涉及一种外齿传动循环水二次滤网。压差计布置并固定于筒体外部，网芯框架固
