Technical Field

[0001] The utility model relates to the technical field of preparation of coal gangue concrete, in particular to a mixer for preparing coal gangue concrete. Background Art

[0002] Gangue is a solid waste discharged during the coal mining and coal washing process. It is a black-gray rock with a low carbon content and harder than coal that accompanies the coal seam during the coal formation process. Abandoned gangue will occupy a large area of ​​land, and the escape or leaching of sulfides in the gangue will pollute the atmosphere, farmland and water bodies. Gangue piles can also spontaneously combust and cause fires, or collapse during the rainy season, silting up rivers and causing disasters. In order to solve the problem of gangue pollution, a variety of ways to treat and utilize gangue have been explored and studied, one of which is to use gangue to make cement admixtures and prepare concrete.

[0003] When preparing coal gangue concrete, it is necessary to mix it with other materials in a certain proportion. A batching machine is used in the configuration process. When the existing batching machine is feeding, the material will be instantly put into the feed bin, which will cause a large impact on the inner wall of the feed bin. When the feeding speed is too fast, the overall fluidity of the material is poor, and the hopper outlet is small, it may also cause blockage in the feed bin, affecting the feeding speed. In addition, the coal gangue stones are of different sizes or small stones are stuck together, which will lead to poor quality of the mixed concrete. Utility Model Content

[0017] Please refer to the attached Figure 1-Figure 3 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0018] The utility model proposes a mixer for preparing coal gangue concrete. When using the device, firstly, a certain proportion of other liquid materials are poured into the mixing box 1 through the opening, and the motor 4 is started. The motor 4 drives the pulley 1 6 to rotate, the pulley 1 6 drives the bevel gear 1 12 to rotate, the bevel gear 1 12 drives the bevel gear 2 13 meshing therewith to rotate, and the bevel gear 2 13 drives a group of stirring rods 11 to rotate through the shaft 10. At the same time, the pulley 1 6 drives the pulley 2 5 to rotate through the belt 3, and the pulley 2 5 drives the U-shaped rod 14 to rotate with the central axis of the pulley 2 5 as the center of the circle. The rotation of the U-shaped rod 14 makes its long rod move in a circular trajectory, and the U-shaped rod 14 drives the movable jaw plate 9 to swing back and forth through the connecting plate, and the movable jaw plate 9 drives the straight groove plate to slide back and forth along the circular axis, so that the coal gangue and other solid granular materials are poured into the discharge box 2. In the crushing chamber, the movable jaw plate 9 cooperates with the fixed jaw plate 8 to crush the solid raw material into small particles. The solid raw material crushed into small particles falls into the liquid raw material in the mixing box 1 through the discharge chamber of the discharge box 2 in sequence and continuously. The solid small particles and the liquid raw materials are mixed and stirred by a group of stirring rods 11. The device first crushes the larger gangue stones, other solid raw materials and stones bonded together into small particles through the crushing and feeding structure. The coal ore crushed into small particles enters the mixing box 1 through the discharge chamber. The solid raw materials continue to fall into the mixing box 1, which improves the problem of poor material fluidity caused by adding more materials at the same time during traditional mixing, and avoids the blockage problem caused by a large number of stones being added at the same time. The gangue and other solid raw materials involved in the mixing are all small particles, which makes the concrete mixing more uniform and the quality better.
