Description

Technical Field

[0001] The utility model relates to the technical field of fly ash processing, in particular to a ball mill for fly ash processing. Background Art

[0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. If a large amount of fly ash is not treated, it will produce dust and pollute the atmosphere. If it is discharged into the water system, it will cause river siltation, and the toxic chemicals in it will also cause harm to humans and organisms. However, fly ash can be utilized as a resource, such as as an admixture for concrete.

[0003] Fly ash ball mill is a key equipment for crushing materials after they are broken. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, non-ferrous metal beneficiation, glass and ceramics and other production industries. It performs dry or wet grinding of various ores and other grindable materials. In the prior art, most ball mills lack components for stirring and breaking up fly ash when feeding it, resulting in a large amount of fly ash being easily accumulated and agglomerated during feeding, thereby blocking the feeding channel and making it impossible to feed the material, so that the fly ash cannot enter the ball mill to be ground, which is not practical enough. Therefore, it is necessary to redesign a ball mill for fly ash processing to address the above problems. Utility Model Content

[0024] A cleaning brush 14 is fixedly installed on the end of the screw sleeve 13, and a feeding pipe 5 cooperating with the cleaning brush 14 is slidably installed on the outer wall of the purification box 6 through a pull-out opening, and a connecting sleeve 16 is fixedly installed inside the feeding pipe 5 through a connecting mechanism. The connecting mechanism includes two connecting rods 15 fixedly installed inside the feeding pipe 5, and the ends of the two connecting rods 15 are fixedly connected to the outer wall of the connecting sleeve 16. An auger blade 17 is rotatably installed inside the connecting sleeve 16. The end of the feeding pipe 5 is fixedly connected to a feeding hopper, and a connecting sleeve 19 is fixedly installed inside the feeding hopper through a connecting mechanism. The connecting mechanism includes two connecting rods 18 fixedly installed inside the feeding hopper, and the ends of the two connecting rods 18 are fixedly connected to the outer wall of the connecting sleeve 19.

[0025] A connecting shaft 20 is rotatably installed inside the connecting sleeve 19, and the outer wall of the connecting shaft 20 is connected to the rotating shaft of the auger blade 17 through a rotating mechanism. The rotating mechanism includes a bevel gear 21 fixedly installed on the rotating shaft of the auger blade 17 and the outer wall of the connecting shaft 20, and the two bevel gears 21 are vertically meshed. A crown gear 22 is fixedly installed on the outer wall of the connecting shaft 20, and a transmission shaft 23 is rotatably installed inside the upper hopper. A second motor 25 connected to the transmission shaft 23 is fixedly installed on the outer wall of the upper hopper through a support plate 24, and a spur gear 26 meshing with the crown gear 22 is fixedly installed on the outer wall of the transmission shaft 23.
