Description

Technical Field

[0001] This utility model belongs to the technical field of coal processing equipment, specifically a powder and block separation device for coal processing. Background Technology

[0002] Coal is an important fossil energy source that has long dominated the global energy structure. It is a combustible sedimentary rock formed from the remains of ancient plants underground through long-term geological processes. Its main components include elements such as carbon, hydrogen, oxygen, nitrogen, and sulfur. Based on the degree of coalification, coal can be divided into anthracite, bituminous coal, lignite, and other types.

Detailed Implementation

[0024] 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.

[0025] like Figures 1 to 5 As shown, this utility model provides a powder and lump separation device for coal processing, including a separation box 1. A square frame 2 is movably fitted to the top of the middle of the separation box 1. A triangular block 3 is fixedly installed on the top of the square frame 2. The outer surface of the triangular block 3 is movably fitted to the inner surface of the separation box 1. Screen plates 4 are hinged to the top of the left and right ends of the square frame 2, respectively. The top of the screen plate 4 is movably connected to the bottom of the triangular block 3. The outer surface of the screen plate 4 is movably fitted to the inner surface of the separation box 1. Rectangular plates 5 are movably connected to the left and right sides of the top of the inner surface of the separation box 1, respectively. A vertical plate 6 is fixedly installed at the middle of the top of plate 5. The top of the vertical plate 6 passes through the separation box 1 and extends to the outside of the separation box 1. A horizontal bar 7 is fixedly installed at the top of the rear end of the vertical plate 6. A short bar 8 is fixedly installed at the middle of the rear end of the horizontal bar 7. A drive motor 9 is fixedly installed at the rear of the left side of the top of the separation box 1. A drive shaft 10 is fixedly sleeved at the other end of the output shaft of the drive motor 9. A long bar 11 is fixedly sleeved on the outer surface of the drive shaft 10. The top of the inner surface of the long bar 11 and the outer surface of the short bar 8 are movably sleeved. The front end of the long bar 11 and the rear end of the horizontal bar 7 are movably connected.

[0026] When the drive motor 9 starts, the drive shaft 10 will drive the long rod 11 to rotate, thereby causing the inner surface of the long rod 11 to exert a thrust on the outer surface of the short rod 8, pushing the short rod 8 and the crossbar 7 to move. This causes the rectangular plate 5 to move along with the crossbar 7 via the vertical plate 6. Since the bottom of the rectangular plate 5 is equipped with a cleaning rod that is compatible with the screen holes of the screen plate 4, the screen holes on the screen plate 4 can be cleaned by the cleaning rod at the bottom of the rectangular plate 5 as the rectangular plate 5 moves, thus preventing blockage.

[0027] Among them, a limiting post 12 is fixedly installed in the middle of the bottom end of the square frame 2, and a bottom frame 13 is movably sleeved on the outer surface of the limiting post 12. The top end of the bottom frame 13 is movably connected to the bottom end of the square frame 2, and the outer surface of the bottom frame 13 is fixedly sleeved on the inner surface of the separation box 1.

[0028] The presence of the bottom frame 13 will provide support for the square frame 2, while the cooperation between the limiting post 12 and the bottom frame 13 will limit the square frame 2, thereby ensuring the stability of the square frame 2 during vibration.

[0029] Among them, a power motor 14 is fixedly installed in the middle of the rear end of the separation box 1. The other end of the output shaft of the power motor 14 is fixedly sleeved with a power shaft 15. The front end of the power shaft 15 passes through the separation box 1 and the bottom frame 13 and extends into the interior of the bottom frame 13, and is fixedly sleeved with an elliptical block 16. The outer surface of the elliptical block 16 is movably sleeved with the inner surface of the bottom frame 13, and the top end of the elliptical block 16 is movably connected with the bottom end of the limiting post 12.

[0030] When the power motor 14 is started, the power shaft 15 will drive the elliptical block 16 to rotate. Since the outer surface of the elliptical block 16 is movably connected to the outer surface of the limit post 12, the frame 2 can be vibrated as the elliptical block 16 rotates.

[0031] Among them, the top of the left and right ends of the frame 2 are respectively movably fitted with a stop block 17, and there are two stop blocks 17. The top of the two stop blocks 17 are respectively movably connected to the bottom of the sieve plate 4. The opposite sides of the two stop blocks 17 are respectively fixedly installed with a movable plate 18, and there are two movable plates 18. The outer surface of the two movable plates 18 is respectively movably fitted with the inner surface of the frame 2.

[0032] With the cooperation of the stop block 17 and the triangular block 3, the position of the sieve plate 4 is locked, thereby ensuring that the sieve plate 4 can remain horizontal.

[0033] Among them, the top of each of the two movable plates 18 is movably fitted with a limiting plate 19, the outer surface of the limiting plate 19 is fixedly fitted with the inner surface of the frame 2, and the bottom of each of the two movable plates 18 is hinged with an inclined plate 20, the number of inclined plates 20 is two and the shape and size are the same.

[0034] When the bottom ends of the two inclined plates 20 move downward, the top ends of the inclined plates 20 will exert a pulling force on the movable plate 18, pulling the two movable plates 18 to move towards each other along the outer surface of the limiting plate 19 with the stop blocks 17 respectively, thereby releasing the lock of the stop blocks 17 on the screen plate 4.

[0035] Among them, the bottom ends of the two inclined plates 20 are hinged with lifting plates 21. The outer surface of the lifting plate 21 is movably connected to the inner surface of the frame 2. An electric telescopic rod 22 is fixedly installed in the middle of the bottom end of the lifting plate 21. The bottom end of the electric telescopic rod 22 is fixedly connected to the bottom of the inner surface of the frame 2.

[0036] When the electric telescopic rod 22 is activated, the lifting plate 21, along with the bottom end of the inclined plate 20, will move along the inner surface of the frame 2.

[0037] Among them, a guide block 23 is fixedly installed at the bottom of the right inner wall of the separation box 1, and an adjustment plate 24 is movably sleeved at the bottom of the middle of the separation box 1. The top of the outer surface of the adjustment plate 24 is movably connected to the bottom of the guide block 23.

[0038] When the adjusting plate 24 rotates, the discharge direction can be adjusted, and the presence of the guide block 23 can prevent powder from accumulating on the top of the adjusting plate 24.

[0039] A servo motor 25 is fixedly installed at the bottom of the middle rear end of the separation box 1. A rotating shaft 26 is fixedly sleeved at the other end of the output shaft of the servo motor 25. The front end of the rotating shaft 26 passes through the separation box 1 and the adjustment plate 24 and extends to the front end of the separation box 1. The outer surface of the rotating shaft 26 and the inner surface of the adjustment plate 24 are fixedly sleeved.

[0040] When the servo motor 25 is started, the rotating shaft 26 will rotate along with the adjusting plate 24, thereby adjusting the discharge direction.

[0041] Among them, a powder tube 27 is fixedly installed on the left side of the bottom end of the separation box 1, and a block tube 28 is fixedly installed on the right side of the bottom end of the separation box 1.

[0042] The presence of the powder pipe 27 will facilitate the discharge of coal powder, while the presence of the block pipe 28 will facilitate the discharge of coal blocks.

[0043] Among them, the feed pipe 29 is fixedly sleeved at the middle of the top of the separation box 1, and the reserved groove 30 located on the rear side of the square frame 2 is opened at the middle of the rear end of the separation box 1.

[0044] The presence of the feed pipe 29 facilitates the entry of raw materials, while the presence of the reserved slot 30 facilitates the wiring of the electric telescopic rod 22.

[0045] Working principle and usage process of this utility model:

[0046] In operation, the operator first starts the power motor 14, causing the power shaft 15 to drive the elliptical block 16 to rotate. This causes the frame 2 and the screen plate 4 to vibrate through the elliptical block 16. The operator then pours the raw material into the separation box 1. Under the vibration of the screen plate 4, the coal powder will be separated through the screen holes on the screen plate 4 and discharged through the powder pipe 27. After the coal powder and the lumps are separated, the operator stops the power motor 14 and starts the servo motor 25, causing the rotating shaft 26 to rotate and contact the left inner wall of the separation box 1. Then, the operator starts the electric telescopic rod 22, causing the lifting plate 21 to move along the inclined plate 20. This causes the inclined plate 20 to exert a pulling force on the movable plate 18, pulling the two movable plates 18 to move towards each other along the outer surface of the limiting plate 19 with the stop blocks 17, until the stop blocks 17 release the lock on the screen plate 4. At this time, under the action of gravity, the screen plate 4 will rotate downward, allowing the coal lumps to be discharged through the lump pipe 28.

[0047] After the coal lumps are discharged, the operator starts the drive motor 9, which causes the drive shaft 10 to rotate the long rod 11. This causes the inner surface of the long rod 11 to exert a thrust on the outer surface of the short rod 8, pushing the short rod 8 through the crossbar 7 and moving the vertical plate 6 and the rectangular plate 5 until the unblocking rod at the bottom of the rectangular plate 5 passes through the screen holes on the screen plate 4. This cleans the screen plate 4 and prevents the screen holes of the screen plate 4 from becoming clogged, which would affect the use of the separation equipment.
