Purpose and Introduction
This device is widely used in urban sewage, industrial wastewater, food processing industry, paper industry and other sewage treatment projects. This device removes floating debris and sediment from the water intake and squeezes and dehydrates the slag before discharging it.

characteristic
The grille and water flow form a 35 ° angle, and due to the formation of a bend, even many pollutants with a thickness smaller than the grille gap can be separated.
The grille is equipped with a flushing device and has a self-cleaning function
The cylindrical structure increases the water flow rate of the grille compared to traditional grilles, reduces head loss, and reduces the stacking plane in front of the grille.
All parts in contact with water are made of stainless steel and undergo acid pickling and passivation treatment. They have strong anti-corrosion performance and long service life in all civil sewage and most industrial water.
By integrating the salvaging, conveying, and pressing of the grille, not only does it save floor space, but it also reduces the cost of subsequent garbage disposal.
Almost no maintenance is required, no refueling is needed on the rotating point, and the number of refueling times for the drive device is extremely small.

Structural working principle
The equipment is installed in the inlet channel at a 35 ° angle to the horizontal plane. Sewage flows through the open port of the grid and enters the channel through the grid bar. The grid bar intercepts solid waste. When the water level reaches a certain difference, the rotating rake located on the central axis rotates inside the grid drum. The teeth of the rotating rake are inserted into the grid bar to clean it and drive it to run upward. When it reaches the highest point, all the grid slag falls into the central grid slag spiral groove and is squeezed and dehydrated by the screw conveyor in the central grid slag spiral groove, and then transported to the upper discharge hopper for discharge.
