Description

Technical Field

[0001] The utility model belongs to the technical field of separators, and provides a pulverized coal and wood chip separator. Background Art

[0002] Pulverized coal and wood chips are easy to distinguish in terms of weight, material, density, shape and color. When the two substances are mixed, pulverized coal particles are distributed in a dot-like manner on the surface of the wood chips. Special separation machinery and equipment are required to separate the two substances.

[0003] The particle size of pulverized coal is much larger than that of wood chips. Usually, the two are separated by vibration screening. In order to facilitate the feeding of pulverized coal onto the coal powder sieve from the feeding port, the inside of the feeding port and the upper surface of the coal powder sieve are kept open. During the vibration of the coal powder sieve, pulverized coal and wood chips are lifted. Due to the lack of measures for collecting the lifted pulverized coal and wood chips, pulverized coal is usually in powder form and is easy to float upward. The open feeding port allows the pulverized coal to disperse in the air, and the dispersed pulverized coal is easy to pollute the environment. The wood chips will also be thrown out of the coal powder sieve as the coal powder sieve vibrates, and the wood chips are splashed inside the separator during the vibration of the coal powder sieve and are difficult to collect. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and solve the problems that the existing pulverized coal and wood chip separator is prone to lifting of pulverized coal and wood chips and is not convenient for collecting pulverized coal and wood chips.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a pulverized coal and wood chip separator, including a fuselage;

[0006] An intermediate partition, a square frame, an inclined plate, a first accommodating cavity, and a second accommodating cavity are sequentially arranged in the fuselage from top to bottom. A first penetration hole that is in the same vertical line as above the inclined plate is opened in the middle of the intermediate partition;

[0007] A sieve hopper is sleeved inside the square frame. A brush is arranged inside the sieve hopper. The upper end of the sieve hopper is slidably connected to the lower end of the intermediate partition, and the lower end of the inclined plate is rotatably connected to the upper end of the sieve hopper;

[0008] A second penetration hole that communicates with the inside of the sieve hopper is opened between the second accommodating cavity and the first accommodating cavity. A shaft body is inserted into the second penetration hole. The upper end of the shaft body penetrates into the shaft body and is detachably connected to the lower end of the brush. The lower end of the shaft body penetrates to the bottom end inside the fuselage.

[0009] Specifically, a feeding channel is installed at the upper end of the fuselage. A hopper is installed at the upper end of the feeding channel. The upper end of the hopper is detachably connected to a cover plate through a detachable connection. The cover plate is flange-connected to a feeding pipe.

[0010] Specifically, a first discharge pipe penetrating through the rear end of the fuselage is connected inside the second accommodation cavity through a flange, and a second discharge pipe penetrating through the rear end of the fuselage is connected inside the first accommodation cavity through a flange.

[0011] Specifically, a first spring fixed to the lower end of the square frame is arranged at each of the four corners inside the first accommodation cavity, and the sieve hopper is surrounded by the first springs.

[0012] Specifically, a limit plug block rotatably connected to one side of the shaft body is fixed inside the second penetration hole. An active plug block is arranged at the front end of the limit plug block and adjacent to the opposite side of the shaft body. The upper end of the active plug block is slidably connected between the first accommodation cavity and the second accommodation cavity. An electric push rod is installed in front of the first accommodation cavity and the second accommodation cavity, and the electric push rod is drivingly connected to the front end of the active plug block.

[0013] Specifically, a bracket is sleeved at the lower end of the shaft body. A motor drivingly connected to the lower end of the shaft body is slidably connected inside the bracket.

A connecting piece sleeved on the outer surface of the shaft body is fixed to the left end of the iron sheet. Limit rings fixed to the outer surface of the shaft body are arranged at both the upper and lower ends of the connecting piece. A second spring is sleeved outside the shaft body between the bracket and the lower limit ring. A guide post adjacent to the second spring and the electromagnet is slidably connected in the middle of the iron sheet.

[0014] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: The cover plate forms a closed accommodation space for the hopper. The feed pipe is used to input the mixture of pulverized coal and wood chips to be separated into the hopper. The feeding channel is used to pour the mixture of pulverized coal and wood chips inside the hopper into the sieve hopper through the first penetration hole. The shaft body, iron sheet, electromagnet, bracket, second spring, limit ring, connecting piece, and guide post are used in cooperation to move the sieve hopper up and down.

Specific embodiments

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a pulverized coal and wood chip separator, including a fuselage 1; a partition plate 6, a square frame 29, an inclined plate 8, a first accommodating cavity 9, and a second accommodating cavity 12 are sequentially arranged in the fuselage 1 from top to bottom. A first penetration hole 7 that is vertically aligned with the upper part of the inclined plate 8 is opened in the middle of the partition plate 6; a sieve hopper 11 is sleeved and arranged inside the square frame 29. A brush 14 is arranged inside the sieve hopper 11. The upper end of the sieve hopper 11 is slidably connected to the lower end of the partition plate 6, and the lower end of the inclined plate 8 is rotatably connected to the upper end of the sieve hopper 11; a second penetration hole 19 that communicates with the inside of the sieve hopper 11 is opened between the second accommodating cavity 12 and the first accommodating cavity 9. A shaft body 15 is inserted into the second penetration hole 19. The upper end of the shaft body 15 penetrates into the shaft body 15 and is detachably connected to the lower end of the brush 14. The lower end of the shaft body 15 penetrates to the bottom end inside the fuselage 1;

[0021] A limit plug block 18 that is rotatably connected to one side of the shaft body 15 is fixed inside the second penetration hole 19. An activity plug block 17 is arranged in front of the limit plug block 18 and adjacent to the opposite side of the shaft body 15. The upper end of the activity plug block 17 is slidably connected between the first accommodating cavity 9 and the second accommodating cavity 12. An electric push rod 16 is installed in front of the first accommodating cavity 9 and the second accommodating cavity 12. The electric push rod 16 is drivingly connected to the front end of the activity plug block 17;

[0022] The lower end of the shaft body 15 is sleeved with a bracket 23, and a motor 22 connected to the lower end of the shaft body 15 is slidably connected inside the bracket 23, and an electromagnet 21 adjacent to one side of the shaft body 15 is installed on the upper end of the bracket 23. An iron sheet 20 is arranged above the electromagnet 21, and a connecting piece 26 sleeved on the outer surface of the shaft body 15 is fixed to the left end of the iron sheet 20, and a limiting ring 25 fixed to the outer surface of the shaft body 15 is arranged at both the upper and lower ends of the connecting piece 26. A spring 24 located between the bracket 23 and the limiting ring 25 at the lower end is sleeved outside the shaft body 15, and a guide column 27 adjacent to the spring 24 and the electromagnet 21 is slidably connected in the middle of the iron sheet 20;

[0023] A feeding channel 5 is installed at the upper end of the fuselage 1, and a hopper 2 is installed at the upper end of the feeding channel 5. The upper end of the hopper 2 is connected with a cover plate 3 through a detachable material, and the cover plate 3 is connected with a feed pipe 4 through a flange. The feed pipe 4 of the cover plate 3 is connected with the inside of the hopper 2 as a whole, and the cover plate 3 forms a closed accommodating space for the hopper 2. The feed pipe 4 is used to input the mixture of coal powder and wood chips to be separated into the hopper 2. The cover plate 3 prevents the mixture of coal powder and wood chips to be separated from splashing from the upper end of the hopper 2 to the external atmosphere. The mixture of coal powder and wood chips to be separated flows downward from the inside of the hopper 2 to the inside of the feeding channel 5 and falls onto the partition plate 6. The mixture of coal powder and wood chips to be separated gradually accumulates inside the penetration hole 7 and falls downward to the surface of the inclined plate 8.

[0024] When the electromagnet 21 is energized, the electromagnet 21 generates a magnetic force to attract the iron sheet 20, and the iron sheet 20 slides down along the guide column 27. The iron sheet 20 is attracted downward to the electromagnet 21 by the magnetic force. The lower end of the shaft body 15 uses the bracket 23 as a reference support point. The iron sheet 20 pushes the limit ring 25 downward to move the shaft body 15 downward. The iron sheet 20 allows the limit ring 25 and the connecting piece 26 to squeeze the spring 24 downward. At the same time, the limit ring 25 compresses the spring 24 and the shaft body 15 moves downward as the limit ring 25 moves downward. The motor 22 moves downward along the inside of the bracket 23, and the upper end of the shaft body 15 pulls down the sieve bucket 11, which slides down along the inside of the frame 29 (the four corners of the accommodating chamber 19 are all provided with a support). A spring 10 is fixed at the lower end of the square frame 29, and the screen bucket 11 surrounds the spring 10. The square frame 29 compresses the spring 10, and the spring 10 buffers the square frame 29. The lower end of the screen bucket 11 moves downward inside the accommodating chamber 9, and the screen bucket 11 pulls down the inclined plate 8. The upper end of the inclined plate 8 slides along the lower end of the partition plate 6. The lower end of the inclined plate 8 rotates along the upper end of the screen bucket 11, and the angle of the inclined plate 8 changes. When the inclined plate 8 is tilted, an angle is formed with the partition plate 6 and the penetration hole 7 is exposed. When the screen bucket 11 moves downward, the penetration hole 7 is opened, so that the coal powder and wood chip mixture inside the hopper 2 is poured into the screen bucket 11 from the penetration hole 7;

[0025] The electromagnet 21 is powered off and loses the magnetic force to attract the iron sheet 20, so that the contracted second spring 24 rebounds. The second spring 24 pushes the limit ring 25 and the connecting piece 26 upward. The iron sheet 20 slides upward along the guide post 27, and the iron sheet 20 is separated from the electromagnet 21. The limit ring 25 and the connecting piece 26 drive the shaft body 15 and the motor 22 to reset. The shaft body 15 moves upward to move the sieve hopper 11 upward along the inner side of the square frame 29 inside the first accommodating cavity 9. The sieve hopper 11 pushes the inclined plate 8 upward. The upper end of the inclined plate 8 slides along the lower end of the spacer plate 6, and the lower end of the inclined plate 8 rotates along the upper end of the sieve hopper 11. The inclined plate 8 gradually becomes parallel to the spacer plate 6, and the inclined plate 8 blocks the first penetration hole 7. When the sieve hopper 11 moves upward, the first penetration hole 7 is closed, so that the mixture of pulverized coal and wood chips stops flowing downward from the first penetration hole 7 into the sieve hopper 11;

[0026] The sieve hopper 11 has a funnel structure in a conical shape. The motor 22 drives the shaft body 15 to drive the brush 14 to rotate along the inner wall of the sieve hopper 11. The surface of the brush 14 rotates and rubs against the inner wall of the sieve hopper 11. The rotating brush 14 agitates the mixture of pulverized coal and wood chips inside the sieve hopper 11. The mixture of pulverized coal and wood chips flows along the inner wall of the sieve hopper 11. The mixture of pulverized coal and wood chips is swept by the brush 14. Since the inclined plate 8 blocks the first penetration hole 7 and blocks the channel for the pulverized coal and wood chips to rise upward inside the sieve hopper 11, the particle size of the pulverized coal is smaller than that of the wood chips. The pulverized coal penetrates downward out of the sieve hopper 11 under the action of gravity. The pulverized coal is screened out by the sieve hopper 11. The separated pulverized coal penetrates from the outer wall of the sieve hopper 11 into the first accommodating cavity 9 inside, while the wood chips are left on the inner wall of the sieve hopper 11, so that the pulverized coal is separated from the wood chips. The electric push rod 16 separates the movable plug 17 from the limit plug 18, so as to expose the second penetration hole 19. The wood chips fall into the second penetration hole 19 inside and the second accommodating cavity 12 inside in sequence from the inside of the sieve hopper 11 by gravity. By respectively arranging the first accommodating cavity 9 and the second accommodating cavity 12 inside the fuselage 1, the separated pulverized coal and wood chips are respectively used for collection;

[0027] The shaft body 15, the iron sheet 20, the electromagnet 21, the bracket 23, the second spring 24, the limit ring 25, the connecting piece 26, and the guide post 27 are used in cooperation to move the sieve hopper 11 up and down. The inclined plate 8 realizes the effect of opening and closing the first penetration hole 7 as the sieve hopper 11 moves up and down. The spacer plate 6, the first penetration hole 7, and the inclined plate 8 are used in cooperation to further prevent the pulverized coal from spreading into the air and at the same time the wood chips will not be thrown out of the sieve hopper 11, ensuring that when the sieve hopper 11 moves up and down, it is convenient to supplement the mixture of pulverized coal and wood chips and at the same time avoid the mixture of pulverized coal and wood chips from spraying out of the first penetration hole 7, and avoid the pulverized coal and wood chips from splashing;

[0028] Inside the second accommodation cavity 12, a first discharge pipe 13 that penetrates through the rear end of the fuselage 1 is connected by a flange. Inside the first accommodation cavity 9, a second discharge pipe 28 that penetrates through the rear end of the fuselage 1 is connected by a flange. The pulverized coal and wood chips are respectively taken out from the inside of the first accommodation cavity 9 and the second accommodation cavity 12 by relying on the second discharge pipe 28 and the first discharge pipe 13. Then, the electric push rod 16 is used to make the movable plug 17 coincide with the limit plug 18 again, so that the second penetration hole 19 is closed again. The above steps are repeated to facilitate the entry into the next processing cycle.
