Support structure of roller and roller screen

Abstract

The invention discloses a support structure of a roller and a roller screen using the support structure. The support structure comprises a support wheel capable of supporting the roller (1) rotationally and a lifting mechanism (2) installed on a base (3), wherein the lifting mechanism comprises a working position and a non-working position; at the working position, the lifting mechanism stretches towards the roller to lift the roller to be away from the support wheel; at the non-working position, the lifting mechanism retracts to reset the roller to the support wheel. Therefore, the lifting mechanism can enter into the working position to lift the roller to be away from the support wheel when the roller does not work, so that the problem that a strip-shaped region of one surface of the support wheel bears a constant load independently for a long term can be avoided, and the problem that the support wheel is pressed for a long time is improved efficiently. Furthermore, the creep deformation problem of the support wheel with the contact surface layer made of an elastic material is solved efficiently. When the roller works, the roller is reset to the support wheel to avoid affecting the normal work of the roller.

Description

technical field [0001] The invention relates to the field of drum support, in particular to a drum support structure and a drum screen using the support structure. Background technique [0002] The drum is applied in various fields in modern production and life, for example, in the municipal solid waste treatment technology, it involves a drum screen, which is mainly used for the screening of raw garbage. Among them, noise and wear are important technical indicators of trommel screens. Therefore, in this trommel screen, elastic materials such as polyurethane are generally used as the supporting roller of the coating layer to support the drum, so as to reduce noise, strengthen friction drive, and prolong the service life. [0003] The supporting rollers are flattened during driving, forming a large enough friction area to facilitate driving the drum. When the drum is running, the flattened position on the supporting wheel is continuously elastically recovered during the rot...

AI Technical Summary

Problems solved by technology

However, when the roller is suspended and standing still, the polyurethane elastomer of the idler will creep under the long-term constant positioning local load, resulting in plastic deformation on the side bearing the pressure of the roller and forming a rut.
