Coal gangue separating device for intelligent separation of coal gangue

Abstract

The invention discloses a coal gangue separating device for intelligent separation of coal gangue. The coal gangue separating device for intelligent separation of coal gangue comprises a separating chamber; a feeding port is formed in the top of the separating chamber; a supporting rod is vertically inserted and connected in the middle of the separating chamber; a jacking mechanism is arranged atthe upper end of the supporting rod; a plurality of supporting grooves are formed in the segment, located in an inner cavity of the separating chamber, of the supporting rod; a screening plate is placed in each supporting groove; a plurality of screening holes are formed in each screening plate, and the density of the screening holes in the screening plates is sequentially increased from top to bottom; the other ends of the screening plates are rotationally connected with the side wall of the separating chamber; and a discharging box is arranged at the end, located on the screening plates, ofthe separating chamber. According to the coal gangue separating device for intelligent separation of the coal gangue, due to vertical movement of the supporting rod, one end of each screening plate islifted or lowered through the corresponding supporting groove, and the angles of the screening plates are changed, and are adjusted according to coal gangue macadam in different numbers so that the coal gangue macadam can be better screened.

Description

technical field [0001] The invention relates to the technical field of coal gangue processing, in particular to a coal gangue separation device for intelligent separation of coal gangue. Background technique [0002] Coal gangue is the solid waste discharged during the coal mining process and coal washing process. It is a black-gray rock with low carbon content and harder than coal that is associated with the coal seam during the coal formation process, including the excavation during the roadway excavation process. Gangue, gangue extracted from the roof, floor and interlayer during the mining process, and gangue picked out during the coal washing process, the coal gangue can be sieved into fine particles for secondary use of the coal gangue, and the existing sorting device is too large. Simple, the screen is fixed at a certain inclination angle, and the gravity of coal gangue falls onto the screen for automatic screening. When the amount of coal gangue falling on the screen...

Gangue, gangue extracted from the roof, floor and interlayer during the mining process, and gangue picked out during the coal washing process, the coal gangue can be sieved into fine particles for secondary use of the coal gangue, and the existing sorting device is too large. Simple, the screen is fixed at a certain inclination angle, and the gravity of coal gangue falls onto the screen for automatic screening. When the amount of coal gangue falling on the screen is large, the coal gangue cannot be effectively screened and separated The quality of coal gangue
