Technical Field

[0001] The utility model relates to the technical field of coal washing, in particular to a multifunctional coal washing device. Background Art

[0002] Coal washing is a process of removing impurities from raw coal through physical, chemical and other methods to improve the quality and utilization value of coal. Through the impact of water flow, raw coal with different components and specific gravities can be separated into different grades, and dust and waste rock can be removed to reduce the ash and sulfur content. This is called coal washing. Coal washing is an indispensable link in coal processing. The coal after coal washing is called clean coal. In addition to achieving the purpose of environmental protection, coal washing can also improve the utilization rate of coal.

[0003] When flushing coal, the existing devices mostly use fixed-direction water nozzles. However, the impact force of the fixed-direction water flow is weak on the coal located nearby, which is not convenient for targeted removal of impurities with strong adhesion, thereby reducing the flushing and impurity removal effect of the device and affecting the production quality of coal.

[0004] Therefore, the utility model provides a multifunctional washing and sorting device to solve the problems raised in the above background technology. Utility Model Content
