[0003] Traditional coal sorting equipment such as heavy medium separation and flotation are not ideal when processing coarse coal slime and cannot meet the production needs of high-quality coal;

[0004] In order to more effectively process the coarse coal slime in coal, improve the utilization rate of coal and reduce resource waste, a coarse coal slime separator with controllable cyclone force is proposed. Utility Model Content

[0007] A further improvement of the technical solution of the utility model is that an air inlet is arranged on one side of the air blowing mechanism and located outside the sorting tank, and a swirl nozzle is arranged on one end of the air blowing mechanism and located inside the sorting tank.

[0008] A further improvement of the technical solution of the utility model is that: the swirl injection mechanism is provided with three groups located on the left side of the sorting tank.

[0010] A further improvement of the technical solution of the utility model is that: the stirring rods are provided in four groups.

[0011] A further improvement of the technical solution of the utility model is that: the limiting groove is arranged on the right inner wall of the sorting groove, and the sorting groove is limitedly inserted with a limiting plate through the limiting groove.

[0012] A further improvement of the technical solution of the utility model is that a sorting net is installed in the limiting plate, and a hook is fixedly installed on the top of the limiting plate.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] 1. The utility model provides a coarse coal slime separator with controllable swirl force. The air blowing mechanism sucks in pressurized air through the air inlet and then sprays it out through the swirl nozzle. By utilizing the swirl principle, a high-speed rotating vortex is generated inside the sorting tank to separate impurities and coal slime in the coal, so that smaller particles can be separated from the sorting tank through the sorting mechanism. The swirl force can be adjusted by the control center to adapt to coal of different particle sizes and densities, thereby achieving a more accurate sorting effect, which can effectively improve the quality and extraction rate of coal and reduce the waste of energy resources.

As the turntable drives the coal slime to rotate highly, the centrifugal force is used to separate the impurities and coal slime in the coal, and the impurities and coal slime in the coal are thrown out of the sorting tank through the sorting mechanism. At the same time, the rotation of the turntable drives the stirring rod and the sorting partition to rotate to break up the coal slime, and the coarse coal slime is sorted in cooperation with the swirl injection mechanism.

The sorting mechanism is connected to the right side of the sorting trough through a limit plate. The sorting mechanism can be lifted and removed by a hook, and sorting nets with different aperture sizes can be replaced to adapt to coal slimes of different particle sizes. It can effectively separate particles with large density differences, realize accurate sorting and processing of coarse coal slime in coal, and improve the quality and utilization rate of coal.

[0027] In this embodiment, the blowing mechanism 22 sucks in pressurized air through the air inlet 21 and then ejects it through the swirl nozzle 23. By utilizing the swirl principle, a high-speed rotating vortex is generated inside the sorting tank 1 to separate impurities and coal slime in the coal, so that smaller particles can leave the sorting tank 1 through the sorting mechanism 5. The swirl force can be adjusted by the control center 3 to adapt to coal of different particle sizes and densities, thereby achieving a more accurate sorting effect, which can effectively improve the quality and extraction rate of the coal and reduce the waste of energy resources.

As the turntable 41 drives the coal slime to rotate highly, the centrifugal force is used to separate the impurities and coal slime in the coal, and the impurities and coal slime in the coal are thrown out of the sorting tank 1 through the sorting mechanism 5. At the same time, the rotation of the turntable 41 drives the stirring rod 42 and the sorting partition 43 to rotate to break up the coal slime, and the swirl injection mechanism 2 is cooperated to sort the coarse coal slime.

As the turntable 41 drives the coal slime High rotation uses centrifugal force to separate impurities and coal slime in the coal, and the impurities and coal slime in the coal are thrown out of the sorting tank 1 through the sorting mechanism 5. At the same time, the turntable 41 rotates to drive the stirring rod 42 and the sorting partition 43 to rotate to break up the coal slime. The swirl injection mechanism 2 is used to sort the coarse coal slime. The sorting mechanism 5 is limited and connected to the right side of the sorting tank 1 through the limiting plate 52.
