Wastewater Treatment stainless steel Mechanical Rake Tooth Bar Screen Rotary bake grille is coarse grille, also known as rainwater grille and reverse grab grille. It is a large coarse grille equipment used to remove large suspended solids in water. This device can continuously and automatically remove liquids. The solid suspended solids, with reasonable design, simple structure, safe and reliable operation, and high degree of automation,can be widely used in large-flow water treatment places such as urban sewage treatment, water plant intake, rainwater pump station, power plant cooling water intake, etc. The structure of the equipment frame refers to the advantages of the rotary grille decontamination machine, and adopts a unique working principle, that is, the rake tooth chain rotates before and after the grid, and when the rake tooth runs to the water facing surface of the grid, it is inserted In the cracks of the fence, make a cleaning action from bottom to top. The rake chain adopts a closed type to prevent debris from intruding and make the equipment run more smoothly. When the equipment is installed, the whole machine is used for hoisting, and only two steel plates are pre-buried on the ground on both sides of the water collection well. The civil construction is simple, cost saving, easy installation and maintenance.
Working Principle
The rotary rake grille decontamination machine consists of a frame, a driving device, a transmission guide wheel, a rake chain combination, rake teeth, a slag barrier, and a slag barrier. Driven by the motor reducer, the slewing drag chain makes a slewing movement from bottom to top on the waterfront surface. When the rake gear shaft on the drag chain runs to the waterfront surface of the grid, the rake teeth are inserted into the gap of the grid and run to the grid. When the bar is facing the water surface, the rake teeth are inserted into the gap of the bar for cleaning from bottom to top, scraping the debris trapped on the bar into the rake, and the removal efficiency is high and complete. When the tine rake moves to the upper part of the machine, the sundries fall off into the container or the upper part of the conveyor by their own weight.
Characteristics
1. Sundries may enter the traction chain and jam the traction chain, so a closed traction chain is designed. It is mainly composed of chain plates, chain pins and rollers. When running, it is guided by the guide rail on the frame, and the rollers roll on the guide rail, with low resistance and stable operation. 2. The positioning of the underwater rotary wheel is made of stainless steel and equipped with wear-resistant steel bearings, which eliminates the daily maintenance of underwater parts. 3. The slag retaining part adopts a fixed grid form, which has strong impact resistance and can withstand large water level differences.
