Description

Technical Field

[0001] This utility model relates to the field of magnesite technology, specifically a low-dust screening structure for a magnesite conveying device. Background Technology

[0002] Magnesite is an important raw material in metallurgy, building materials, and chemical industries. Its processing requires screening to achieve particle classification and impurity removal. The metallurgical industry needs to screen magnesite of specific particle size for use as a smelting flux. The building materials industry needs to remove fine powder impurities from magnesite to improve the strength of products. The chemical industry requires magnesite of uniform particle size to ensure reaction efficiency. In the magnesite processing, it needs to be transported first, and a screening structure needs to be set at the end of the transport device for final screening. However, the current screening structure of magnesite transport devices does not have a dust removal function, which causes the dust generated during screening to directly spread in the workshop, polluting the environment and endangering health. To address this, we propose a low-dust screening structure for magnesite transport devices. Utility Model Content

[0003] The purpose of this utility model is to provide a low-dust screening structure for magnesite conveying devices, which has the advantage of dust removal function. This solves the problem that the current screening structures for magnesite conveying devices do not have dust removal function, causing the dust generated during screening to directly diffuse into the workshop, polluting the environment and endangering health.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-dust screening structure for a magnesite conveying device, comprising a base plate, a screening box fixedly connected to the top of the base plate via a bracket, an annular rotating rod rotatably connected to the inner cavity of the screening box via a bearing, a screen cylinder fixedly connected to the other end of the annular rotating rod, a motor fixedly connected to the right side of the screening box, the output shaft of the motor fixedly connected to the right side of the screen cylinder, an air suction hood embedded in the top of the inner cavity of the screening box, a dust collection box fixedly connected to the rear end of the top of the base plate, a filter screen provided in the upper part of the inner cavity of the dust collection box, a connecting pipe fixedly connected to the upper part of the back of the dust collection box, the other end of the connecting pipe fixedly connected to the air suction hood, a fan fixedly connected to the top of the dust collection box, and the air intake of the fan fixedly connected to the top of the inner cavity of the dust collection box via a pipe.
