Description

Technical Field

[0001] The invention relates to the technical field of coal gangue sorting equipment, and in particular to a hydrocyclone for sorting coal gangue. Background Art

[0002] Gangue is a solid waste discharged during the coal mining and washing process. It is a black-gray rock with a low carbon content and harder than coal that is associated with the coal seam during the coal formation process. Gangue can replace clay as a raw material for brick making. The combustibles of gangue itself can be used to save coal when burning bricks. Gangue can also partially or completely replace clay components to produce ordinary cement, special cement and clinker-free cement. In addition, gangue can also be used to sinter lightweight aggregate for the construction of high-rise buildings. Hydrocyclone is a grading device that uses centrifugal force to accelerate the sedimentation of ore particles and is widely used in many fields. Hydrocyclone is mainly composed of feed pipe, cyclone cylinder, cyclone core tube, discharge pipe, etc. When liquid (such as slurry, river water, wastewater, etc.) enters the hydrocyclone from the feed pipe along the tangential direction at a high speed, due to the limitation of the outer cylinder wall, the liquid is forced to rotate from top to bottom. This movement is called external cyclone or descending cyclone movement. In the external cyclone, solid particles are acted upon by centrifugal force. If their density is greater than that of the surrounding liquid, the centrifugal force they are subjected to will be greater than the liquid resistance caused by the movement, causing the solid particles to move toward the wall and separate from the suspension. The hydrocyclone for gangue separation achieves effective separation of coarse and fine particles in the mixed slurry of gangue through the action of centrifugal force, and has the advantages of high efficiency, simple structure, and easy operation.

[0003] In the prior art, coarse-grained gangue is discharged from the sand settling port at the bottom of the conical cylinder to become sand, which is then transmitted through a pipeline. If the pipeline is used for too long, there may be residual accumulated impurities and blockages, which is not conducive to maintaining a good working condition of the cyclone and will reduce its service life. In addition, the gangue contains substances that are harmful to the environment (such as heavy metals, etc.), and it is difficult to meet environmental protection requirements if it is not cleaned after sorting. Therefore, a hydraulic cyclone for sorting gangue is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that coarse-grained coal gangue is discharged from the sand settling port at the bottom of the conical cylinder to become sand, and the sand will be transmitted out through a pipeline.

In addition, the coal gangue contains substances harmful to the environment (such as heavy metals, etc.), and it is difficult to meet environmental protection requirements if it is not cleaned after sorting.

[0031] A cleaning box 12 is provided below the sand settling port 2, and a gangue cleaning mechanism is provided inside the cleaning box 12. The gangue cleaning mechanism includes a second motor 13 provided inside the cleaning box 12, and a transmission rod 14 is provided at the output end of the second motor 13. A soft brush cylinder 15 is fixedly connected to the side of the transmission rod 14 away from the second motor 13, and a first gear 16 is fixedly connected to the side of the transmission rod 14 close to the second motor 13. The side of the first gear 16 is meshedly connected to the second gear 17. The operation of the second motor 13 causes multiple groups of soft brush cylinders 15 to simultaneously change from a stationary state to a rotating state;

[0032] The base plate 3 is fixedly connected to the first motor 4, the end of the threaded rod 5 away from the first motor 4 is rotatably connected to the base plate 3, the T-plate 6 is slidably connected to the base plate 3, the moving rod 7 is slidably connected to the sand settling port 2, and a feed port 10 is provided at the top of the hydrocyclone cylinder 1;

[0033] The cleaning box 12 is fixedly connected to the second motor 13, and a discharge chute is provided below the cleaning box 12 to transport the coarse coal gangue particles out;

[0034] A partition 20 is fixedly connected inside the cleaning box 12, and the transmission rod 14 is rotatably connected to the partition 20. The partition 20 can isolate the second motor 13 from the soft brush cylinder 15.

[0035] A water spray assembly 21 is fixedly mounted on one side of the cleaning box 12 near the partition 20 .

[0036] In this embodiment, a sand settling port 2 is fixedly provided at the bottom of the hydrocyclone cylinder 1, and a base plate 3 is fixedly connected below the sand settling port 2. The cleaning mechanism provided inside the base plate 3 is started, and the first motor 4 fixedly installed on the inner wall of the base plate 3 starts to run. When the first motor 4 runs, it starts to control the threaded rod 5 provided at its output end to rotate, and the other end of the threaded rod 5 rotates inside the base plate 3. The external thread of the threaded rod 5 is threadedly connected with a T-shaped plate 6, and the T-shaped plate 6 rotates inside the threaded rod 5 and generates a spiral power. Since the T-shaped plate 6 is slidably connected to the inside of the base plate 3, the T-shaped plate 6 starts to slide inside the base plate 3, but does not rotate therewith. When the T-shaped plate 6 moves, it drives the other parts thereof. The moving rod 7 fixedly connected between the two ends starts to move, and the other side of the moving rod 7 is fixedly connected with a circular cleaning plate 8, which is arranged inside the sand settling port 2 and is slidably connected to the inner wall of the sand settling port 2, so that when the moving rod 7 moves, the circular cleaning plate 8 is driven to slide the inner wall of the sand settling port 2 to clean the residue on the inner wall of the sand settling port 2, and the staff can process the residue through the opening of the sand settling port 2. There is a certain distance between the end of the sand settling port 2 that is not an opening and the connection between the hydrocyclone cylinder 1, so that the circular cleaning plate 8 stays on this side when it is not moving, does not affect the sand settling operation of the hydrocyclone cylinder 1, and completes the residue cleaning operation on the inner wall of the sand settling port 2;

[0037] A cleaning box 12 is provided below the sand settling port 2. The gangue cleaning mechanism provided inside the cleaning box 12 is started, and the second motor 13 in the gangue cleaning mechanism starts to run. The second motor 13 is fixedly installed inside the cleaning box 12. When the second motor 13 runs, it starts to control the transmission rod 14 provided at its output end to rotate. The other end of the transmission rod 14 is fixedly connected to a soft brush cylinder 15, so that when the transmission rod 14 rotates, the soft brush cylinder 15 is driven to rotate inside the cleaning box 12. A first gear 16 is fixedly connected to one side of the transmission rod 14 close to the second motor 13. When the transmission rod 14 rotates, it drives the first gear 16 to start rotating. The side of the first gear 16 is meshed with a second gear 17. When the first gear 16 rotates, it drives the first gear 16 to start rotating. The second gear 17 starts to rotate, so that when the second gear 17 rotates, it drives another group of soft brush cylinders 15 to rotate. The second gear 17 is provided with multiple groups, so that multiple groups of second gears 17 drive multiple groups of soft brush cylinders 15 to rotate at the same time. The first gear 16, the second gear 17, and the second motor 13 are isolated from the multiple groups of soft brush cylinders 15 by the partition 20 fixedly connected inside the cleaning box 12. The multiple groups of soft brush cylinders 15 rotate to clean the coarse particles of coal gangue that are sanded out of the sand settling port 2. Water spray components 21 are fixedly connected on both sides of the cleaning box 12. The two groups of water spray components 21 flush the coarse particles of coal gangue below. The flushed coarse particles of coal gangue are transmitted out through the discharge trough provided inside the cleaning box 12.

[0038] Embodiment 2

[0039] like Figure 1-Figure 7 As shown, based on the first embodiment, an overflow port 9 is provided on one side of the hydrocyclone cylinder 1 close to the feed port 10, and a support rod 11 is fixedly connected to the bottom of the hydrocyclone cylinder 1;

[0040] A filter plate 18 is provided below the soft brush cylinder 15, the filter plate 18 is fixedly connected to the cleaning box 12, and a waste water tank 19 is fixedly connected below the filter plate 18;

[0041] A baffle 22 is fixedly connected to the side of the cleaning box 12, and a base frame 23 is fixedly connected below the baffle 22;

[0042] A driving assembly 24 is arranged above the base frame 23, a transmission assembly 25 is arranged on the side of the base frame 23 close to the driving assembly 24, a conveyor belt 26 is rotatably connected to the side of the base frame 23 close to the baffle 22, and the conveyor belt 26 is rotatably connected to the baffle 22, and the driving assembly 24 can drive the conveyor belt 26 to rotate.

[0043] In this embodiment, the feed port 10 fixedly connected at the top of the hydrocyclone cylinder 1 is used for inputting the coal gangue slurry material, and the overflow port 9 is fixedly connected to the side of the hydrocyclone cylinder 1 near the feed port 10, while the fine particles and liquid medium continue to move upward in the hydrocyclone cylinder 1 in the countercurrent, and are discharged from the overflow port 9 at the top of the hydrocyclone cylinder 1 to become overflow, and the coarse coal gangue is discharged from the sand settling port 2 at the bottom of the hydrocyclone cylinder 1 to become sand set. A filter plate 18 is arranged at the bottom of the cleaning box 12, and the wastewater washed with the coarse coal gangue passes through the filter plate 18 and enters the wastewater tank 19 fixedly connected to the bottom of the filter plate 18, so that the staff can treat the wastewater. When the multiple groups of soft brush cylinders 15 close to the top of the filter plate 18 rotate, the coarse-grained coal gangue can be pushed out of the cleaning box 12, so that the processed coarse-grained coal gangue enters the outside of the conveyor belt 26 from the cleaning box 12. At this time, the driving component 24 is started. The driving component 24 is fixedly installed in the frame structure of the base frame 23. When the driving component 24 is running, it drives the transmission component 25 fixedly installed on the other side of the base frame 23 to start running, so that the transmission component 25 can drive the conveyor belt 26 to rotate outside the base frame 23. Baffles 22 are fixedly connected on both sides of the conveyor belt 26. When the conveyor belt 26 transports coarse-grained coal gangue, the baffles 22 can prevent the coarse-grained coal gangue from falling from the outside of the conveyor belt 26, thereby ensuring stability during transportation.
