Self-anti-blocking system of sewer

Abstract

The invention belongs to the field of urban sewer cleaning, and relates to a self-anti-blocking system of a sewer. The self-anti-blocking system of the sewer comprises a fixing pipe; a water inlet cavity is formed in the fixing pipe; a reverse swing device is arranged in the middle of the interior of the water inlet cavity; the reverse swing device is used for rotating sewage entering the water inlet cavity; an extrusion device is arranged at the front end of the water inlet cavity and used for extruding garbage entering the water inlet cavity to reduce the size; and an opening and closing device is arranged at the rear end of the water inlet cavity and used for storing and intensively discharging the sewage entering the water inlet cavity. According to the invention, relatively large garbage is compressed before the sewage enters a pipeline, meanwhile, the movement of running water is simulated for the sewage entering the pipeline, and the sewage serves as a cleaning source to flush the pipeline wall, so that the inner wall is cleared, and meanwhile sludge precipitation is prevented.

Description

technical field [0001] The invention belongs to the field of urban sewer cleaning, in particular to a sewer self-blocking prevention system. Background technique [0002] As we all know, the sewage in urban sewers contains a large amount of domestic garbage, etc. In the sewers, due to the slow flow rate, a large amount of silt in the static sedimentation place, and the mixing of silt and garbage often causes serious sewer blockage. The common solution is to rely on manpower , using the method of high-pressure water gun flushing to flush the silt and garbage blocked at the mouth of the sewer. This method first needs to enter the sewer artificially. The environment in the sewer is very bad, it is very unfriendly to the staff, and there are many dangers in the sewer , such as biogas explosions, bacterial infections, etc., and the method of washing with high-pressure water guns often requires a large amount of water, which will also cause a large degree of waste of water resourc...
