A sorting device for impurities in coal

Abstract

The invention relates to the field of coal mine separation, in particular to a coal debris separation device and a control system thereof. The material is crushed by the crushing mechanism and then enters the extrusion mechanism through the discharge mechanism. The material is further shrunk through the extrusion of the rotating roller, reducing the deviation of the material diameter and the diameter deviation between the materials, and providing for the next step of screening. In order to improve the convenience, the primary crushing and secondary extrusion work coherently, which improves the work efficiency. The invention is designed with a sorting mechanism, which drives the servo motor to drive multiple connecting arms to rotate, the sixth connecting arm rotates around the second connecting shaft, and then drives the eighth connecting arm to reciprocate, the material falls to the screen hole, and the vibrating motor Under the action of the sieve plate, the material shakes up and down, which can remove the light impurities in the coal, and the heavier coal falls from the sieve hole. Due to the reciprocating movement of the sieve plate, the possibility of the material blocking the sieve hole is greatly reduced, and it is better Sorting is realized, and secondary extrusion is performed for a small amount of larger materials.

Description

technical field [0001] The invention relates to the field of coal mine separation, in particular to a coal debris separation device and a control system thereof. Background technique [0002] my country's coal reserves are abundant, but the distribution is uneven. Most of the coal resources are stored in the arid and water-scarce western regions. The selection rate of coal in our country is low, and the selection ratio of steam coal is even lower, which has caused serious resource waste and environmental pollution problems. China's coal resources are mainly distributed in arid and water-scarce areas, accounting for 2 / 3 of the country's coal reserves. A considerable number of young coal types in China are prone to mud when exposed to water, so wet separation is not suitable. [0003] The volume of dry coal resources is relatively large, and if they are directly crushed, the obtained materials still have different volumes, and secondary screening may be required, which reduce...
