Grating capable of automatically separating suspension matters

Abstract

The invention discloses a grating capable of automatically separating suspension matters. The grating is vertically mounted at an overflow port of a municipal pipe network which is connected to a mounting structural well or on a structure of a water inlet of a detention tank; the grating comprises a grating outer frame, grating bars, grating cleaning scrapping teeth, a grating hydraulic driving shaft, grating rotary cleaning teeth, a grating gate and a grating gate hydraulic shaft; the grating bars are distributed in the grating outer frame; the grating cleaning scrapping teeth are verticallyarranged on the grating bars; the grating rotary cleaning teeth are arranged at two ends of the grating outer frame; the grating hydraulic driving shaft is vertically connected to the grating cleaningscrapping teeth and the grating rotary cleaning teeth; the grating gate is arranged at the land side of the grating; and one end of the grating gate hydraulic shaft is arranged on the structure and the other end of the grating gate hydraulic shaft is connected to the grating gate. According to the technical scheme, secondary pollution of the suspension matters in an overflow water body to a received water body can be prevented; backflow of the water body into the pipe network can be prevented; a function of automatically cleaning the suspension matters, which are blocked on the grating bars,can be achieved; and the effectiveness of the municipal pipe network in drainage and pollution reduction can be enhanced.

Description

technical field [0001] The invention relates to a cleaning control device for suspended matter in a municipal drainage pipe network, a rainwater storage tank or a sewage purification tank, in particular to an intelligent control device for a municipal drainage network, a rainwater storage tank or a sewage purification tank Grille for automatic separation of suspended matter. Background technique [0002] At present, the drainage pipe network in some old urban areas in my country mostly adopts the combined system, that is, domestic sewage and rainwater are discharged into the downstream sewage treatment plant through one pipe, and the planning and construction of the drainage pipe network is early, and the sewage discharge capacity cannot adapt to the current situation. stage requirements; although some emerging urban drainage pipe networks adopt the diversion pipe system, that is, domestic sewage and rainwater are discharged into the downstream sewage treatment plant and rain...

AI Technical Summary

Problems solved by technology

The grids of the above grid devices are all perpendicular to the grid bars, and are mainly set up for the grid room of the sewage treatment plant and the water inlet of the pumping station. grid device

In addition, none of the above-mentioned grille devices is designed with a gate closing system, and there is no grille closing door, so the purpose of closing the storage tank for maintenance cannot be achieved, and there are no automatic cleaning strips at both ends of the above-mentioned grille device
