Crush type grid

Abstract

The invention discloses a crush type grid which comprises a reduction motor, a coupler box, a transmission shaft box, a diversion bracket provided with a diversion port and a tail box, wherein the reduction motor, the coupling box, the transmission shaft box, the diversion bracket and the tail box are vertically installed from top to bottom; the output shaft of the reduction motor is connected with the upper end of a driving shaft through a coupling in the coupling box; a driven shaft is parallel to the driving shaft, the upper ends and the lower ends of the driving shaft and the driven shaftare respectively supported in the transmission shaft box and the tail box through bearings, the middle parts of the driving shaft and the driven shaft penetrate through the whole diversion bracket, the driven shaft is connected with the driving shaft through a transmission mechanism, coupling type cutter assemblies are respectively installed on the driving shaft and the driven shaft in a corresponding way in the diversion bracket. The invention can crush solid substances such as cloth strips, wood chips, empty glass jars and the like mixed in a sewer to prevent water treatment equipment of thesewer from being blocked, and ensure normal operation of the water treatment equipment. The equipment can be used by matching with a traditional pump station, and can be singly used, thereby changingan application form of the traditional pump station.

Description

Technical field [0001] The present invention is a device related to sewage treatment of sewers, in particular a crushing grid, that is, a grating with a grinder, and is mainly a device developed for crushing and processing solid waste mixed in the sewer. The equipment can crush solids such as cloth pieces, wood chips, empty bottles and cans mixed in the sewer to prevent the clogging of the sewer process equipment and ensure the normal operation of the sewer water treatment equipment. The equipment can be used in conjunction with the traditional pumping station or used alone, thus changing the application form of the traditional pumping station. Background technique [0002] China's water resources per capita are small and their spatial distribution is uneven. With the acceleration of urbanization and industrialization in China, the demand for water resources is also increasing. In this context, the sewage treatment industry has become an emerging industry, currently in the same...

Problems solved by technology

However, the biggest threat to the downstream equipment (especially the sewage pump) in the sewage is some soft and flexible impurities, such as cloth strips, wood chips, plastic bags, rubber gloves, etc., which are easy to bypass the grille with the water flow and wind up to the pump impeller. on, thereby reducing the performance of the pump and the life of the pump impeller

These flexible impurities are also easy to wrap around the grid, block the grid gap, reduce the water passing efficiency of the grid, and affect the performance of the grid

Traditional grills capture solid waste and require manual or mechanical salvage and removal, which is likely to cause secondary pollution
