Anti-blocking rotary type mechanical grid

Abstract

The invention provides an anti-blocking rotary type mechanical grid. The anti-blocking rotary type mechanical grid is provided with a rack; the bottom of the rack is fixed on a canal bottom plane through a supporting frame; the upper part of the rack is fixed on a ground plane through a fixed steel plate; the anti-blocking rotary type mechanical grid is characterized in that a dreg discharging hole is further formed in the rear end of the upper part of the rack; a transmission mechanism is arranged at the top of the rack; a limiting switch is arranged on one side of the transmission mechanism; the rack is connected with a traction chain through the transmission mechanism; the traction chain is a sealed type traction chain; a dirt removing harrow is arranged at the upper part of a front side face of the rack; the dirt removing harrow is arranged above the ground plane; a plurality of harrow teeth are distributed in the traction chain; each group of the harrow teeth do self-cleaning movement relatively; grids are further arranged in the traction chain, so that impurities are prevented from invading and stable running of equipment is guaranteed; the working efficiency is improved and the overhauling cost is reduced.

Description

technical field [0001] The invention belongs to the field of environmental protection machinery and relates to a mechanical grille, in particular to an anti-blocking rotary mechanical grille. Background technique [0002] In the current water treatment process, the large-scale coarse grille equipment used to remove suspended solids mainly includes high-chain grille decontamination machines, traditional wire rope traction grille decontamination machines, etc. During the operation of these equipments, the impurities are easy to be mixed, and the cleaning is not thorough, and the fine impurities are easy to escape from the grille, or easily entangled on the grille to block the grid gap. When encountering hard objects such as wooden blocks, bamboo poles, branches, etc., it is easy to jam or damage the equipment, and the wire rope traction grille decontamination machine may also have messy ropes, so the separation effect is poor, the efficiency is low, and the operation is not no...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the defect that the existing mechanical grille is easy to block and cause equipment damage, the invention provides an anti-blocking rotary mechanical grille, which can prevent the intrusion of sundries, ensure the stable operation of the equipment, improve work efficiency, and reduce maintenance costs
