Description

Technical Field

[0001] The utility model is applicable to the technical field of coal production, and particularly relates to a coal gangue sorting device. Background Art

[0002] At present, gangue is solid waste discharged during coal mining and coal washing. It is a black-gray rock with a lower carbon content and harder than coal that accompanies coal seams during the coal formation process. Nowadays, when sorting gangue, people often use the flow rate of water, the different densities of gravel, gangue and water, the mechanical principles of liquid level and slope, and the movement characteristics of water to separate the mineral material gangue and metal gravel, thereby achieving the grading and recovery of gangue.

[0003] However, nowadays, after the gangue is sorted by water, the light and floating gangue will float on the surface of the water body, and the operator needs to manually pick up the floating gangue. This sorting and picking method is too cumbersome, which increases the labor consumption of the operator. Moreover, for a large number of gangue, it is impossible to quickly and automatically salvage and move the gangue, which affects the production efficiency of coal. Therefore, we propose a gangue sorting device. Utility Model Content

[0004] The main purpose of the utility model is to provide a coal gangue sorting device, which can effectively solve the problems in the background technology.

[0007] A driving frame is rotatably mounted on the inner side of the fixed frame, a blowing fan blade is fixedly mounted on the outer surface of the driving frame, a wind guide cover is fixedly connected to the side of the fixed frame, a connecting plate is fixedly sleeved on the outer surface of each rotating rod, a fixed sleeve is fixedly mounted on the side surface of each connecting plate away from the rotating rod, an air blowing pipe is fixedly sleeved between the inner sides of the two groups of fixed sleeves, and the side of the air guide cover and the side of the air blowing pipe are fixedly connected;

[0008] An exhaust groove is provided on one side of the air blowing pipe away from the air guide cover.

[0009] By adopting the above technical scheme, the airflow is transported to the liquid surface inside the sorting tank body under the transmission rotation action of the rotating rod and the connection action of the air guide cover and the air blowing pipe, so that the coal gangue floating after sorting accumulated on the surface of the sorting liquid can be blown and moved, thereby reducing the labor consumption of the operator in picking it up and ensuring the sorting efficiency of the coal gangue.

[0010] As an optional solution of the technical solution of the present application, a mounting frame is fixedly installed on the outer surface of the fixed plate, a servo motor is fixedly installed inside the mounting frame, and the side of the servo motor transmission shaft is fixedly connected to the outer surface of the rotating rod through a coupling.

[0011] By adopting the above technical solution, the rotation adjustment processing of the installation frame is realized through the driving action of the servo motor.

[0012] As an optional solution of the technical solution of the present application, both ends of the side of the sorting tank body are fixedly connected with drainage pipes.

[0013] By adopting the above technical solution, the discharge and replacement treatment of part of the selected water in the sorting tank can be achieved through the structural action of the drainage pipe.

[0014] As an optional solution of the technical solution of the present application, a storage frame is detachably mounted on the surface of one end of the outside of the sorting pool body away from the fixed plate by bolts, and a feed trough is provided on the side of the sorting pool body away from the fixed plate, and the feed trough is located above the storage frame.

[0015] By adopting the above technical solution, the collection, storage and processing of the moving coal gangue can be achieved through the structure of the feed chute.

[0017] 1.

[0018] 2. A coal gangue sorting device of the technical solution of the present application is provided with a storage frame on the outside of the sorting tank body, so that when the coal gangue is blown and sorted, the coal gangue can be moved inside the sorting tank body to be collected and stored, thereby avoiding the random scattering of the sorted coal gangue and affecting the subsequent sorting efficiency.
