Abstract

The utility model relates to an anti-blocking roller screen, belonging to grain material screening equipment, which solves the problems that the material to be screened is very viscous with high water volume and damp grain blanks off all screen holes while screening, making the screening impossible. The utility model adopts the technical proposal that the anti-blocking roller screen comprises a frame, a bearing support, a motor, a reducer, a screening roller, an anti-blocking clearing gear and a seal cover. The screening roller comprises a main shaft roller frame and a circular screen strip. The circular screen strip is fixedly connected with the inner side of the roller frame. The anti-blocking cleaning gear is inserted in the upper half column screen hole of the screening roller. The screening roller is supported by the bearing support on the frame, rotating with the help of the motor and the reducer. The anti-blocking cleaning gear rotates driven by the screening roller. The roller and the anti-blocking cleaning gear are arranged in the seal cover. The utility model has the advantages of simple structure, low manufacturing cost, high screening efficiency and low running cost.

Description

Anti-blocking rotary screen

Technical field

This is a kind of anti-blocking rotary screen, belongs to the granule materials screening plant.

Background technology

Existing rotary screen is big to water content height, viscosity, the wet granular material can all block sieve aperture when screening, causes and can't sieve.

Summary of the invention

The anti-blocking rotary screen of the utility model has solved that water content height, viscosity are big, the wet granular material can all block sieve aperture when screening, cause the problem that can't sieve.

The aufbauprinciple of this anti-blocking rotary screen is: anti-blocking rotary screen is made up of support, motor, reductor, bearing block, screening drum, anti-blocking cleaning gear and seal closure.Screening drum is by main shaft and cylinder skeleton and circular grating is fixing forms, anti-blocking cleaning gear inserts in the screening drum first half bar shaped screen hole, screening drum is supported by the bearing block on the support, by the motor and speed reducer driven rotary, anti-blocking cleaning gear is by the screening drum driven rotary, and screening drum and anti-blocking cleaning gear are installed in the seal closure.

The advantage of the anti-blocking rotary screen of the utility model is:

1, low cost of manufacture simple in structure

2, screening efficiency height

3, operating cost is low
