Description

Technical Field

[0001] This utility model relates to the field of composite material screening technology, specifically an environmentally friendly composite material screening device. Background Technology

[0002] In today's era of advocating green and sustainable development, environmentally friendly composite materials, with their advantages of recyclability, low pollution, and high performance, are widely used in many fields such as building materials, automobile manufacturing, aerospace, and packaging. Screening, as a key process in the processing and production of environmentally friendly composite materials, separates material particles of different sizes, shapes, and densities to ensure uniform and stable product quality, meeting the requirements of subsequent processing and use.

[0003] The prior art discloses an environmentally friendly multi-stage refractory material screening device (publication number CN218486491U), including a screening box and supporting legs. An adjustment cavity is fixedly provided at the top of one side surface of the screening box. This invention utilizes filter plates and fixing bolts. In actual use, personnel can lift the filter plates according to the required degree of refractory material screening, then push the filter plates containing the qualified filter screens into the screening box for subsequent screening operations. The fixing bolts then secure the filter plates, preventing movement during screening and ensuring normal screening.

[0004] The aforementioned environmentally friendly composite material screening device allows for easy adjustment of screening dimensions and convenient replacement of damaged filter screens by pulling the filter plates out from inside the device. It eliminates the need for prolonged downtime for maintenance, ensuring high overall operational efficiency and offering the advantage of convenient replacement and maintenance. However, this device can only screen out large particles of impurities and cannot screen dust impurities, resulting in poor performance during use. Improvements are needed in this regard.
