Description

Technical Field

[0001] The utility model belongs to the field of intercepting devices, and specifically relates to an intercepting device for sewage treatment. Background Art

[0002] Sewage is domestic wastewater and some toilet feces generated in our daily life and production. In order to save the limited fresh water resources on the earth, it is necessary to treat the generated sewage. When treating sewage, it is necessary to first use an intercepting device to intercept large-volume garbage in the sewage.

[0003] A Chinese patent with the publication number CN213388041U discloses an intercepting device for sewage treatment in a sewage treatment tank, including an intercepting bottom plate. On the left and right sides of the top of the intercepting bottom plate, first cylinders are fixedly installed. The output ends of the two first cylinders are fixedly installed with support plates. The top of the two support plates is fixedly welded with an intercepting box. On the left side of the inner cavity bottom of the intercepting box, a waterproof box is arranged. In the middle position of the inner cavity bottom of the waterproof box, a motor is fixedly installed. The output end of the motor is fixedly installed with a winding mechanism passing through the top of the waterproof box through a coupling. On the upper ends of the left and right side walls of the waterproof box, a positioning mechanism fixedly connected to the inner cavity bottom of the intercepting box is symmetrically installed. This intercepting device for sewage treatment in a sewage treatment tank discharges sewage into the intercepting box, starts the motor to drive the installation vertical shaft to rotate, and then drives the five fixing rings and the winding cross bar to rotate synchronously, so as to wind the strip-shaped garbage on the winding mechanism, preventing it from blocking the intercepting net and affecting the flow of sewage, thereby facilitating the interception of strip-shaped garbage in the sewage. However, in this intercepting device for sewage treatment in a sewage treatment tank in this application, although a winding mechanism is provided, there will still be some broken garbage intercepted by the intercepting net. The garbage is intercepted on the intercepting net, which is likely to continuously affect the flow rate of the intercepting net and the sewage treatment effect of the intercepting device.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model
