Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibrating screen technology, and in particular to a JDS multi-layer matrix type special grading screen. Background Technology
[0002] A multi-layer grading screen is a device used for material classification and screening. Through the combination of multiple screen surfaces, it separates materials of different particle sizes according to size, and is widely used in mining, building materials, chemical, and food processing industries. Its core principle is to utilize the vibration or movement of materials on the screen surface, allowing materials smaller than the screen openings to pass through and enter the next layer, while materials larger than the screen openings remain in the current layer, thus achieving the classification of materials of different particle sizes.
[0003] Existing equipment, such as CN220825090U, a multi-layer aluminum ash screening and grading screen, belongs to the field of aluminum ash screening technology. It addresses the problems of low efficiency and insufficient sorting caused by clogging during aluminum ash screening. The screen includes a sorting box with vertically distributed discharge channels on both side walls. A screen plate is rotatably connected between the two side walls of the discharge channels. Two symmetrically arranged support plates are fixed to the inner walls of both sides of the sorting box. This invention uses a lifting component to reciprocate the lifting of the screen plate, which, in conjunction with support springs, can drive the screen plate to flip up and down. This improves the sorting effect of the screen plate when screening aluminum ash, reduces the risk of clogging, and increases screening efficiency. The feeding component feeds aluminum ash into the sorting box in batches for screening, avoiding the problem of insufficient screening caused by screening too much aluminum ash at once. This makes the screening of aluminum ash more uniform and further improves the screening effect.
[0004] Most existing grading screens are integrated units, which are cumbersome to transport, inconvenient for future expansion, unable to meet changing needs, and difficult to maintain when malfunctions occur. Improvements are needed. Utility Model Content
