[0002] Gangue is solid waste discharged during the coal mining and coal washing processes. It is a black-gray rock with a low carbon content and harder than coal that accompanies coal seams during the coal formation process. If gangue is abandoned, it will occupy large tracts of land. The escape or leaching of sulfides in the gangue will pollute the atmosphere, farmland and water bodies. Gangue mountains will also spontaneously combust and cause fires, or collapse in the rainy season, silting up rivers and causing disasters. In order to eliminate pollution, the gangue will be crushed and mixed, and the resulting gangue powder can be used in power generation or as a building material.

[0003] The existing gangue processing equipment in some individual coal mining companies and small-scale enterprises has many deficiencies during use.

The coal gangue powder falls on a pair of inclined plates 6 and a semicircular plate 9. The upper end of the liquid inlet pipe and the crushing box 1 are covered with a sealing cover, and the motor 7 is started. The motor 7 drives the bevel gear 12 to rotate, and the bevel gear 12 drives the rotating shaft 14 and the bevel gear 2 13 meshing therewith to rotate. The bevel gear 2 13 drives the stirring assembly to rotate and stir through the circular shaft 8. The rotating shaft 14 The two groups of support rods 15 drive the corresponding group of cutters 5 to rotate with the rotating shaft 14 as the center, and the two groups of cutters 5 slide along the inner wall of the semicircular plate 9. At the same time, the rotating shaft 14 drives the corresponding pulley 2 to rotate, and one pulley 2 drives the other pulley 2 to rotate through the belt 3, and the other pulley 2 drives the rotating rod 10 to rotate. The rotating rod 10 drives the knocking ball 11 to rotate with the rotating rod 10 as the center through the round rod. The qualified coal gangue powder in the crushing box 1 can directly fall into the mixing box 4 through the through holes of the semicircular plate 9 and a pair of inclined plates 6 for mixing, and unqualified coal gangue particles and The gangue powder mass slides along a pair of inclined plates 6 into the semicircular plate 9, is broken up and crushed by two sets of cutters 5, the qualified powder falls into the mixing box 4 for mixing, and the unqualified powder continues to be crushed in the semicircular plate 9. When the knocking ball 11 rotates to the vicinity of the highest position, it knocks the semicircular plate 9 to make the semicircular plate 9 vibrate, promote the falling of the powder, and avoid the powder blocking the through hole and affecting the falling of the powder. After the stirring is completed, the motor 7 is turned off and the valve is opened to take out the finished product. The device first removes the incompletely crushed and damp powder through the crushing structure. The lumps of coal gangue powder are broken up and crushed into powder, and the crushed coal gangue powder falls into the mixing box 4 through the through holes of the semicircular plate 9 for mixing, and the unqualified powder continues to be crushed in the semicircular plate 9. The knocking ball 11 of the knocking structure repeatedly knocks the bottom of the semicircular plate 9 to assist in promoting the falling of the powder and avoid the clogging of the through holes by the powder. The device realizes the functions of simultaneous crushing and stirring, makes the subsequent stirring more uniform, and has multiple uses. It eliminates the time of first crushing and then transporting the coal gangue powder to the stirring equipment, and improves the stirring efficiency.
