drum bar screen drum filter for wastewater treatment

Purpose and Introduction

HG-II type rotary drum filter is one of the latest complete sets of equipment for water supply and drainage pretreatment developed by our company. It is designed with reference to imported equipment. This equipment is widely used in urban sewage, industrial wastewater, food processing industry, paper industry, etc. Sewage treatment project. The equipment salvages and removes the floating debris and sediments at the water intake, squeezes and dehydrates the screen slag and discharges it.

Structure and working principle:

The equipment is installed in the water inlet channel at a 35° angle to the horizontal plane. The sewage flows from the open port of the grille through the grille into the channel. The grille intercepts the solid dirt. When the water level difference reaches a certain level, the rotary rake positioned on the central axis It rotates in the scale drum, and the rotating rake teeth are inserted into the grid bars to clean the grid bars and drive them to run upward. When running to the highest point, all the grid slag falls into the spiral groove of the central grid slag and passes through the central grid slag. The screw conveying press in the spiral groove is squeezed dry, dehydrated, and transported to the upper discharge hopper for discharge.

main feature

The grid and the water flow form an angle of 35 degrees, because of the formation of the baffle, even many dirt with a thickness smaller than the grid gap can be separated.

The grille is equipped with a flushing device and has a self-cleaning function

The cylindrical structure enables the grid to increase the flow of water through the grid compared to the traditional grid, reduce the head loss, and reduce the accumulation plane in front of the grid.

All parts in contact with water are made of stainless steel and are treated with acid pickling and passivation, which has strong anti-corrosion performance and long life in all civil sewage and most industrial water.

Through the integrated salvage, conveying, and pressing of the grille, the floor space is saved, and the subsequent treatment cost of garbage is also reduced.

Almost no maintenance is required, no oiling is required at the swivel point, and the drive is refueled very little.
