[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 , Figure 2 As shown, a coarse coal slime separation device includes: a flotation tank 1 for separating coarse coal slime, wherein the flotation tank 1 is provided with a rising bubble pipe 11, and a fluid distribution plate 12 is provided on the rising bubble pipe 11. The rising bubble pipe 11 generates upward bubbles, which form an upward water flow through the fluid distribution plate 12 to achieve the purpose of flotation of coarse coal slime; a feeding mechanism 2 provided above the flotation tank 1, the feeding mechanism 2 including a distributor 24; a pushing mechanism 3 provided at the top of the flotation tank 1, the pushing mechanism 3 including a first hydraulic rod 31 and a propeller 32; a guide channel 4 provided at the top of the flotation tank 1, the guide channel 4 being provided with a blocking block 41; a hopper 5 provided at the bottom of the flotation tank 1; and an opening and closing valve 6 provided at the bottom of the hopper 5.

[0024] The feeding mechanism 2 also includes: a mounting wall 21 located at the top of the flotation tank 1, the mounting wall 21 being an upward extension of the flotation tank 1, the inner side of the mounting wall 21 being on the same plane as the inner wall of the flotation tank 1; a feed pipe 22 penetrating the mounting wall 21, the feed pipe 22 being inclined, the coarse peat to be separated being fed at the higher end of the feed pipe 22, and then the coarse peat being fed from the lower end; a connecting rod protruding from the mounting wall 21, the connecting rod being connected to the fixed end of the rotary motor 23, and the output end of the rotary motor 23 being fixedly connected to the distributor 24.

[0025] The top of the feeder 24 has an opening, and the output end of the rotary motor 23 passes through the opening and is fixed to the bottom of the feeder 24. The rotary motor 23 drives the feeder 24 to rotate. The outlet of the feed pipe 22 is located above the feeder 24. The coarse slurry to be separated enters the feeder 24 directly after passing through the feed pipe 22. The bottom of the feeder 24 has several feeding ports 241. The coarse slurry to be separated in the feeder 24 is dispersed in the feeder 24 under the drive of the rotary motor 23 and falls evenly in the feeding ports 241. After falling evenly, it is easy to separate gangue and clean coal, reduce the conflict between gangue and clean coal during flotation, and improve the separation efficiency.

[0026] The mounting wall 21 is equipped with a protective cover 211, which surrounds the outlet 51 of the feed pipe 22 and the opening of the distributor 24. The protective cover 211 prevents some of the lighter coarse coal slime from being blown outward when the distributor 24 rotates, thus affecting the normal operation of the sorting.

[0027] The fixed end of the first hydraulic rod 31 is fixed to the side wall of the flotation tank 1, and the propeller 32 is fixed to the telescopic end of the first hydraulic rod 31. The extension of the first hydraulic rod 31 drives the propeller 32 forward. The top surface of the propeller 32 is higher than the water surface of the flotation tank 1, thereby ensuring that the propeller 32 can push the clean coal floating on the water surface.

[0028] The two sides of the propeller plate 32 are in contact with the inner wall of the flotation box 1 to ensure that clean coal does not leak from the sides when it is pushed. The upper top surface of the inner wall of the flotation box 1 in contact with the propeller plate 32 is provided with a heightening plate to prevent coal slurry from flowing out from the sides when it is pushed. The front end of the propeller plate 32 is provided with a guide plate 321, which is perpendicular to the propeller plate 32. The extension direction of the guide plate 321 is horizontal with the water surface. A separation port 13 is opened on the side of the flotation box 1 near the guide channel 4. The separation port 13 penetrates the side wall of the flotation box 1. The separation port 13 and the guide plate 321 are on the same plane. The width of the guide plate 321 is greater than the width of the separation port 13, and the height of the guide plate 321 is lower than the height of the separation port 13. The guide plate 321 can be inserted into the separation port 13.

[0029] like Figure 3 As shown, the separation port 13 is connected to the guide channel 4. The sealing block 41 is slidably connected to the separation port 13. The ends of the separation port 13 and the guide channel 4 are provided with slide rails 8, and the sealing block 41 is slidably connected to the slide rails 8. The rear end of the sealing block 41 is provided with a spring 42, which is fixedly connected to the guide channel 4. When the spring 42 is in its normal state, it pushes the sealing block 41 in the separation port 13 to prevent water from flowing out of the separation port 13. As the pilot plate 321 moves, it pushes the sealing block 41 to move, causing the spring 42 to contract and the sealing block 41 to disengage from the separation port 13. Thus, the flotation clean coal is pushed out of the separation port 13 by water and flows into the guide channel 4.

[0030] A water supply pipe 14 is provided at the upper part of the separation port 13. The water supply pipe 14 is used to replenish the water flowing into the guide trough 4, so that the bottom layer of the separated clean coal is located at the upper part of the separation port 13, ensuring that the clean coal can enter the guide trough 4.

[0031] The end of the guide channel 4 is connected to the peat centrifuge 7, which is existing technology. The bottom surface of the guide channel 4 is an inclined surface, with the end closer to the peat centrifuge 7 being lower than the end farther away from the peat centrifuge 7. The clean coal and water entering the guide channel 4 flow into the peat centrifuge 7 in the middle of the inclined surface, and the peat centrifuge 7 performs dewatering operations, thereby separating the clean coal.

[0032] The hopper 5 is conical, and the bottom of the hopper 5 is provided with a discharge port 51. When the valve 6 is not open, the denser gangue settles into the hopper 5 during the sorting process and accumulates at the bottom of the hopper 5.

[0033] The opening and closing valve 6 includes: a second hydraulic rod 61 fixed to the outer wall of the hopper 5; and a sealing plate 62 fixed to the telescopic end of the second hydraulic rod 61. The sealing plate 62 is slidably connected to the discharge port 51. When the second hydraulic rod 61 is in the retracted state, the sealing plate 62 blocks the discharge port 51, preventing material from being discharged from the discharge port 51. When the second hydraulic rod 61 is extended, the sealing plate 62 disengages from the discharge port 51, allowing the precipitated gangue to be discharged from the discharge port 51.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
