Device integrating solid crushing and coarse and fine gratings

Abstract

The invention discloses a device integrating solid crushing and coarse and fine gratings, which relates to a sewage treatment device, in particular to a solid crushing device with the coarse and fine gratings. The device comprises a coarse grating and crushing device (1), a fine grating and crushing device (2), a water inlet (3), a water outlet (4), a coarse grating (5), a fine grating (6), an electromotor (7), a gearbox (8), a rotating brush shaft (9), a reamer shaft (10), a rotating brush holder (11), a rotating brush (12), a reamer (13), a dreg storage chamber (14), a dreg discharging valve (15) of the coarse grating and crushing device, a dreg discharging valve (16) of the fine grating and crushing device, a dreg discharging main pipe (17), an inspection manhole (18), a corresponding water fender, a deflector, a bracket, pipeline fittings and the like. The device integrating the coarse and fine gratings and solid crushing is in a fully-closed structure and is free from the volatilization of foul smell and the propagation of flies. The device has the characteristics of novel constitution, low energy consumption, small occupied area, convenience in management, environment-friendliness and the like, and is worth popularization and application.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an integrated device for solid crushing and coarse and fine grids. Background technique [0002] With the rapid development of social economy, the discharge of industrial sewage and domestic sewage is increasing day by day. The sewage contains large particles of impurities, such as fibers, plastics, wood strips, sand and gravel, etc. Sewage treatment must have grilles, small sewage treatment Generally, it is one grille, and the sewage treatment plant has two grilles, which are coarse grille and fine grille. The grilles are both manual grille and automatic grille. After the grid is lifted by the transmission, the solid matter is compressed and transported out. The grids are all set in the grid wells, especially the grid wells of the sewage treatment plant are all open, so the malodorous gas in the grid wells of the sewage treatment plant volatilizes and flies Breeding is the most poll...

AI Technical Summary

Problems solved by technology

[0003] The invention provides an integrated device for solid crushing and coarse and fine grids. The invention solves the need for manual salvage of the solid matter produced by the existing manual grid, which has high labor intensity; the automatic grid is set in the grid well, and the foul gas in the grid well volatilizes , fly breeding, and need more auxiliary equipment for compression, there are problems such as occupying a large area, high cost, large energy consumption, cumbersome maintenance, etc.
