Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig for coal washing and separation. Background Technique

[0002] Coal preparation is the most economical and effective technology for the rational utilization of coal resources and environmental protection. With low processing costs, it is an essential foundation and key for coal deep processing and clean coal production. On the one hand, it can optimize the coal product structure and improve the utilization rate. On the other hand, a large amount of gangue can be removed before transportation, saving transportation capacity and reducing coal costs. Therefore, coal washing equipment has become the main equipment in coal production, and its production efficiency index is of great significance to coal preparation production. Among many ore dressing fields, jigs occupy an extremely important position. A jig is a gravity ore dressing equipment that uses water as the ore dressing medium and separates according to the specific gravity of minerals.

[0003] At present, the jigs used at home and abroad do not have the function of feeding pretreatment. The feeding of the jig is required to be uniform and stable, and it needs to be wetted with water. Otherwise, agglomeration and unstable bed layer will occur during the coal washing process. Especially when the content of fine coal is large, agglomeration will seriously affect the coal washing accuracy. For this reason, in the process design, measures such as adding a coal feeder in front of the jig are mostly used to solve this problem. As a result, the process has increased links, the elevation loss in the plant has increased, the floor area of the workshop has increased, the system investment has increased, and the equipment failure rate has increased.

The coal is repeatedly struck against the counterattack plate 8 by the impact of the plate hammers 26 on the crushing roller 6, so that the crushing operation of the agglomerated coal can be completed. By setting the three-component feeding cylinder 9, the coal can be dispersed and transported. By setting the anti-blocking mechanism, the situation of coal blockage inside the feeding cylinder 9 can be avoided. By setting the belt conveyor 17, the coal can be transported into the jig body 1. By setting the spreading mechanism, the coal can be spread evenly. Thus, through the above structure, the functionality of the jig is improved, the uniformity of coal feeding is ensured, and the precision of coal washing is effectively improved.
