Description

Technical Field

[0001] The utility model relates to the technical field of gangue processing and utilization, in particular to a device for mixing gangue and coal fly ash. Background Art

[0002] Coal gangue is solid waste discharged during coal mining and coal washing. It is a black-gray rock with a low carbon content and harder than coal that accompanies coal seams during the coal formation process.

[0003] There is a small amount of heat in coal gangue. By reasonably controlling the dosage and stabilizing the thermal system of the kiln system, coal consumption can be reduced and production costs can be saved. However, the existing coal gangue particles are of different sizes, and most of the coal gangue is directly piled up outdoors for storage. Direct use is prone to moisture and affects subsequent mixing, so it needs to be improved. Utility Model Content

By arranging the air intake fan in the air intake pipe, a person can turn on the air intake fan to intake air into the shell through the air intake pipe.

[0015] Preferably, a connecting pipe is embedded and fixed on the top surface of the processing tank, and the end of the connecting pipe facing away from the processing tank is embedded and fixed in the collecting hopper. By embedding and fixing the end of the connecting pipe facing away from the processing tank in the collecting hopper, the processed coal gangue in the collecting hopper can be discharged into the processing tank through the connecting pipe.

[0016] Preferably, a fixing frame is installed on the bottom end surface of the processing tank, and the bottom end surface of the fixing frame is welded to the bearing base.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] 1. The utility model sets a frame and a collecting hopper. When mixing the gangue and the coal fly ash, the personnel can place the gangue and the coal fly ash on the conveyor belt. When placing, the personnel can open the driving mechanism to drive the connecting shaft to rotate. When the connecting shaft rotates, the conveyor belt can be driven to transport the gangue and the coal fly ash, so that the gangue and the coal fly ash can be transported and fall into the collecting hopper, so as to load the crops. When transporting, the personnel can turn on the electric heating pipe to heat and dry the gangue and the coal fly ash transported in the shell to avoid accumulation and moisture. During processing, an air intake fan is set in the air intake pipe, so that the personnel can turn on the air intake fan to intake air into the shell through the air intake pipe, so that the internal gas can circulate for drying operation, thereby meeting the transportation of later materials.

[0020] 2. The utility model provides a processing tank. When personnel mix the gangue and the coal pulverized ash, and the gangue and the coal pulverized ash fall into the collecting hopper after being transported, the personnel can open the second driving mechanism to drive the crushing wheel to rotate. When the crushing wheel rotates, the gangue can be crushed, thereby preventing the gangue particles from being too large to affect the subsequent processing. After crushing, the gangue and the coal pulverized ash enter the processing tank, so that the personnel can open the first driving mechanism to drive the connecting rod through the rotating shaft to mix the gangue and the coal pulverized ash, thereby meeting the subsequent mixing operation and utilizing the gangue.
