AI Technical Summary

Technical Problem

Existing crushing and screening devices used in rubber processing have low screening efficiency and are unable to effectively remove impurities such as sand and gravel stuck to the rubber mass, resulting in the need for multiple cleaning and screening mechanisms, wasting space and increasing production costs.

Method used

A stirring device is set in the crushing device, which includes several plate-shaped and spiral blade stirring structures rotating around the same axis. The water source and the rotating motion of the stirring structure are used to separate the rubber mass from sand, gravel and soil, and suspended stirring and discharging are achieved through the filter plate to avoid blockage.

Benefits of technology

It improves screening efficiency and cleanliness, reduces the need for cleaning and screening mechanisms, and reduces production costs.

Abstract

The present invention belongs to the field of rubber processing technology, and in particular, relates to a crushing and screening device for rubber processing, comprising a box body, a crushing device is provided at the upper part of the box body, a stirring device is rotatably provided at the bottom end of the box body, a filter plate is provided in the box body, and the stirring device is located at the upper end of the filter plate; the stirring device includes a plurality of plate-shaped stirring structures, and the plurality of stirring structures rotate along the inner wall of the box body around the same rotating shaft, and each stirring structure rotates around its own axis; a discharge port is provided on one side of the box body above the filter plate, and the box body is filled with a water source, and the water source continuously overflows from the discharge port. The present invention stirs and screens the rubber mass at all angles within the first time after the rubber is crushed, and achieves unblocked discharge, greatly improving the screening efficiency and cleanliness, thereby reducing the setting of cleaning and screening mechanisms on the entire rubber processing line.
