Product profile

Rotary Bar Screen machine is a kind of special water treatment equipment which can continuously and automatically intercept and remove all kinds of shapes and sundries in the fluid. It can be widely used in the treatment of municipal sewage. Tap water industry, power plant intake, but also can be used as textile, food processing, paper, leather and other industries in the wastewater treatment process of the front sieve equipment, is currently one of the most commonly used solid-liquid screening equipment.

Operational Principle

Rotary Bar Screen machine is a unique rake assembled into a group of revolving grille chains. Under the drive of the motor reducer, the chain of the rake chain turns against the water flow.

When the rake teeth chain runs to the upper part of the equipment , due to the guide of the groove wheel and the bending rail , a relatively self - cleaning movement is generated between each group of rakes. Most of the solid matters fall by gravity , and the other part is used for cleaning the sundries stuck on the rake teeth by the reverse motion of the sweeper .

Characteristics of equipment

The equipment has the advantages of high automation degree , high separation efficiency , low power consumption , no noise and good corrosion resistance . Continuous and stable work can be guaranteed in the case of unattended work. An overload safety protection device is set up, which automatically stops when the equipment fails, so that the equipment can be overloaded.

The device can adjust the running interval of equipment according to the needs of users, and achieve periodic operation. It can be automatically controlled according to the level difference before and after the grid. And it has the manual control function, in order to facilitate maintenance.

When the equipment is working, it has a strong self-purification ability. So it will not be blocked, so the daily maintenance work is very little.

Scope of application

1, For papermaking, slaughtering, leather, sugar, wine, food processing, textile, printing and dyeing, petrochemical and other industrial wastewater treatment, removal of suspended matter, floating matter, sediment and other solid substances.

2, Used in papermaking, alcohol, starch, food processing and other industries in the recovery of fiber, slag and other useful substances.

3, It is used to replace the primary settling tank in the treatment of municipal sewage.
