Technical Field

[0001] The invention relates to the technical field of material mixing, and in particular to a device and method for preparing a mixing material of a solid waste-based coal mine filling material. Background Art

[0002] Solid waste-based coal mine filling material mixing mainly refers to a technology that uses solid waste as coal mine filling material. This approach can not only deal with solid waste, but also improve the safety of coal mining and resource utilization efficiency.

[0003] This kind of filling material mixing usually involves the following aspects: 1. Solid waste materials: including industrial waste, construction waste, solid residues after treatment of domestic waste, etc. These wastes need to be processed and modified before they can become suitable mine filling materials; 2. Filling technology: The treated solid waste materials are mixed with other mining materials (such as cement, gypsum, etc.) in a certain proportion to make fillers. These fillers are used in mines to fill goaf areas, stabilize mine structures, and reduce the risks of mine subsidence and collapse; 3. Environmental protection and economic benefits: The use of solid waste-based filling materials can reduce the impact of waste on the environment, while reducing the cost of filling materials and improving the economic benefits of mines.

[0004] The application of this technology can help coal mining enterprises realize resource recycling and environmental protection while ensuring safe production. Solid waste-based coal mine filling materials can not only effectively utilize solid waste and reduce environmental pollution, but also solve the problem of goaf areas left after coal mining to a certain extent, and ensure the safety of coal mines. The research and application of solid waste-based coal mine filling materials embodies the concept of resource recycling and environmental protection, and is one of the important ways to promote the development of green mining.

An agitator 180 is rotatably provided inside the mixing chamber 120, and a second motor 190 is installed on the outside of the body 100. The second motor 190 is used to drive the agitator 180. A discharge port 220 is opened at the bottom of the body 100, and a sealing plate 230 is rotatably inserted at the bottom of the body 100. The sealing plate 230 is used to seal the discharge port 220.

[0036] A fourth rotating shaft 231 is fixedly installed at the edge position of the bottom of the blocking plate 230, and the middle part of the fourth rotating shaft 231 is rotatably inserted into the bottom of the body 100 through a bearing, and a second mounting frame 232 is fixedly installed at the bottom of the fourth rotating shaft 231. A one-way bearing 233 is sleeved at the lower end of the third rotating shaft 210, and the outer ring of the one-way bearing 233 is sleeved with a sixth gear 234 meshing with the second mounting frame 232. The inner ring of the one-way bearing 233 is fixedly fitted with the third rotating shaft 210, and the outer ring of the one-way bearing 233 is fixedly fitted with the sixth gear 234.

At the same time, when the solid waste moves in the feeding chamber 110, due to the spiral structure of the feeding roller 130, the rotating feeding roller 130 can transport the solid waste and perform preliminary mixing at the same time. Subsequently, the solid waste falls from the feeding chamber 110 into the mixing chamber 120, and at the same time, the cement in the storage tank 140 also continues to evenly fall into the mixing chamber 120. The second motor 190 rotates forward to drive the agitator 180 to rotate to quickly stir and mix the solid waste and cement, thereby preparing a filling material; The second motor 190 is reversed to drive the sealing plate 230 to rotate one hundred and eighty degrees to expose the discharge port 220, and then the second motor 190 is rotated forward to drive the agitator 180 to rotate, and the filling material mixed in the mixing chamber 120 is continuously pushed to the discharge port 220 to complete the discharge, thereby increasing the speed of raw material mixing, thereby improving the efficiency of filling material preparation, and solving the problem of the prior art as much as possible, usually solid waste and raw materials such as cement are put into the mixer together, and the raw materials are mixed evenly by the mixer, and then taken out from the mixer after being prepared into the filling material. However, putting the raw materials together makes it difficult for the mixer to quickly mix the raw materials evenly, which easily affects the efficiency of filling material preparation.
