Air convection crushing device with preliminary crushing function

Abstract

The invention discloses an air convection crushing device with a preliminary crushing function. The air convection crushing device comprises a base, wherein a crushing box is arranged at the top of the base; a material placing rack and a crushing device is arranged inside the crushing box; a preliminary crushing chamber is formed in the top of the a filtering plate; a support plate is arranged at the top of the preliminary crushing chamber; a feeding pipe, a crushing motor and a dust sucking pipe are arranged at the top of the support plate. The air convection crushing device is simple in structure, reasonable in design and convenient to use; an air inputting device and an air extracting device are arranged, so that hot air can be input into the crushing box by the air inputting device and is used for crushing the material, then the air is exhausted by the air extracting device, so that the device forms air convection and is capable of continuously heating the material and avoiding excessive pressure intensity in the crushing box; filter screens are arranged in an air inlet branch pipe, an air outlet branch pipe and a dust sucking branch pipe; the smoothness of the branch pipes can be ensured; the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a crushing device, in particular to an air convection crushing device with a preliminary crushing function. Background technique [0002] With the rapid development of industry, the garment industry has also been well developed. In the garment production process, there will be a large amount of lint and unused rags. If these rags and lint are not cleaned up in time, not only If the working environment is polluted, there will be a risk of fire. If these rags are discarded directly as garbage, it will be a part of the loss. If they can be used reasonably, it will not only reduce environmental pollution, but also save production costs for enterprises. Therefore, some When crushing raw materials and rags, a crushing device will be used. Some crushed materials can be crushed better when heated. The upper end of the commonly used crushing device is not equipped with a protective cover, and the dust will not only fly when the material...

[0002] With the rapid development of industry, the garment industry has also been well developed. In the garment production process, there will be a large amount of lint and unused rags. If these rags and lint are not cleaned up in time, not only If the working environment is polluted, there will be a risk of fire. If these rags are discarded directly as garbage, it will be a part of the loss. If they can be used reasonably, it will not only reduce environmental pollution, but also save production costs for enterprises. Therefore, some When crushing raw materials and rags, a crushing device will be used. Some crushed materials can be crushed better when heated. The upper end of the commonly used crushing device is not equipped with a protective cover, and the dust will not only fly when the material is introduced into the feed box. , pollute the working environment, and too much dust will cause damage to the machinery and equipment and reduce the service life; the commonly used crushing device is not very effective, and there are often larger particles that have not been completely crushed. When these particles pass through the conveying pipe It is easy to block the pipeline, resulting in low working efficiency of the crushing device
