Description

Technical Field

[0001] The present invention relates to the technical field of coal preparation, and in particular to a coal preparation separator and a use method thereof. Background Art

[0002] Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus and other elements. It is a very important energy source and an important raw material for the metallurgical and chemical industries.

[0003] During the processing, coal needs to be screened to remove the gangue in the coal and reduce the impurity content in the coal. High-quality coal can better meet market demand. The common removal method now is through visual inspection. When the visual inspection head detects the gangue in the coal, the telescopic device drives the push plate to move, so that the push plate can push the gangue out of the conveying equipment.

[0004] However, when the coal moves with the conveying mechanism, dust will be generated. The dust is easy to adhere to the lens of the visual inspection head. The dust attached to the lens will block the visual inspection head, resulting in the inability of the visual inspection head to stably and accurately select the gangue, thereby reducing the separation effect of coal and gangue. For this reason, we propose a coal separation machine and its use method. Summary of the invention

[0021] The present invention also provides a use method of a coal preparation separator, including the following steps:

[0022] Step 1: After the coal material enters the frame, it is moved and conveyed by the conveying component. Then, the vision detection head works to conduct visual detection on the coal material on the conveying component. When gangue is detected, the telescopic cylinder works to drive the push plate to move. The push plate pushes the gangue on the conveying component out and discharges it from the frame through the chute, and the remaining coal material continues to move through the conveying component;

[0023] Step 2: When cleaning the lens of the vision detection head, the servo motor works to drive the first rotating rod to rotate forward. The rotation of the first rotating rod drives the first bevel gear to rotate. The rotation of the first bevel gear drives the engaged second bevel gear to rotate. The rotation of the second bevel gear drives the lead screw to rotate. The rotation of the lead screw can drive the slider to move. The movement of the slider drives the movable plate to move. The movement of the movable plate drives the square frame to move. The movement of the square frame drives the brush bristles to move until the brush bristles contact the lens of the vision detection head for cleaning;

[0024] Step 3: While the movable plate moves, it will drive the first gear to move. While the first gear moves, it cooperates with the first rack to drive the first gear to rotate. Then, under the connection of the connecting rod, the first piston moves back and forth inside the connection cavity, so that under the cooperation of the second one-way valve and the first one-way valve, and under the connection of the connection groove, the rectangular ring cavity continuously intakes air, making the inside of the rectangular ring cavity in a positive pressure state. While the square frame moves, it drives the first connecting block to move until the first inclined surface contacts the second inclined surface, so that the second inclined surface squeezes the first inclined surface, causing the first connecting block to descend. Then, through the connection of the connecting rod, it drives the second piston to descend, so that the exhaust groove communicates with the rectangular ring cavity, and the positive pressure in the rectangular ring cavity blows air upward through the exhaust groove, so as to clean the cleaned brush bristles;

[0025] Step 4: While the second inclined surface squeezes the first inclined surface, the fourth inclined surface will squeeze the third inclined surface, causing the second connecting block to move upward, and under the connection of the vertical rod, it drives the second gear to move upward. Then, under the meshing cooperation of the second gear and the third rack, the lifting rod moves upward. The upward movement of the lifting rod drives the movable strip to move upward. The upward movement of the movable strip drives the comb teeth to move upward, and the brush bristles can be cleaned by the upward movement of the comb teeth;

[0026] Step 5: While the first rotating rod rotates forward, it will drive the second synchronous wheel to rotate. Then, under the connection of the synchronous belt, it drives the first synchronous wheel to rotate, and then drives the second rotating rod to rotate. The rotation of the second rotating rod will drive the fan blades to rotate forward. The forward-rotating fan blades will generate negative pressure suction below the fan blades, so as to suck the dust combed off the brush bristles by the comb teeth.

[0027] The technical effects and advantages of the present invention:

[0028] (1) By setting up the cleaning mechanism and cooperating with the fixing mechanism, when the square frame moves to drive the brush bristles to clean the lens of the vision detection head, the first piston will move back and forth with the movement of the movable plate to inflate the rectangular ring cavity, making the rectangular ring cavity in a positive pressure state, and then discharging air to the position of the brush bristles through the exhaust groove, thus ensuring that the vision detection head can detect more clearly, and at the same time ensuring that the brush bristles can clean stably;

[0029] (2) By setting up the combing mechanism, the fourth inclined plane squeezes the third inclined plane, causing the second connecting block to move upward, and driving the second gear to move upward under the connection of the vertical rod. Then, under the meshing cooperation of the second gear and the third rack, the lifting rod moves upward. The upward movement of the lifting rod drives the movable strip to move upward, and the upward movement of the movable strip drives the comb teeth to move upward, so that the brush bristles can be cleaned by the upward movement of the comb teeth, thereby improving the cleaning effect of the brush bristles;

[0030] (3) By setting up the air extraction mechanism, through the operation of the air extraction mechanism, the dust cleaned from the brush bristles can be sucked out, so that the dust leaves the frame body, avoiding these dusts from adhering to the lens of the vision detection head again. At the same time, the air extraction mechanism and the movement of the movable plate share a servo motor. When the servo motor operates, the first rotating rod rotates forward and drives the second synchronous wheel to rotate. Then, under the connection of the synchronous belt, the first synchronous wheel is driven to rotate, and the second rotating rod can be driven to rotate. The rotation of the second rotating rod drives the fan blade to rotate forward, and the forward rotating fan blade generates negative pressure suction below the fan blade, thereby sucking the dust combed off from the brush bristles by the comb teeth, reducing the equipment cost.

A first one-way valve 304 is installed inside the air inlet hole 303. An air outlet hole 305 is formed on the back of the inner wall of the connecting cavity 301. A second one-way valve 306 is installed inside the air outlet hole 305. The first one-way valve 304 only allows air to enter the air inlet hole 303 from the outside, and the air in the air inlet hole 303 cannot be discharged through the first one-way valve 304. The second one-way valve 306 enables the air in the air outlet hole 305 to be discharged through the second one-way valve 306, while the outside air cannot enter the air outlet hole 305 through the second one-way valve 306. A rectangular ring cavity 307 is formed inside the square frame 202. A connecting groove 308 is formed between the rectangular ring cavity 307 and the air outlet hole 305. A plurality of exhaust grooves 309 are formed at the top end of the square frame 202 and at the position of the bristles 203. An adjusting mechanism for controlling the communication between the exhaust grooves 309 and the rectangular ring cavity 307 is arranged inside the rectangular ring cavity 307. The moving mechanism includes a first rack 313. Slots 310 are formed on both sides of the movable plate 201. The inside of the slots 310 is communicated with the inside of the connecting cavity 301.

Then, under the connection of the connecting rod 314, the first piston 302 moves back and forth inside the connecting cavity 301. Thus, under the cooperation of the second one-way valve 306 and the first one-way valve 304,Under the connection of the connecting groove 308, air continuously enters the rectangular ring cavity 307, making the inside of the rectangular ring cavity 307 in a positive pressure state. While the square frame 202 moves, it drives the first connecting block 404 to move until the first inclined surface 405 contacts the second inclined surface 407. The second inclined surface 407 squeezes the first inclined surface 405, causing the first connecting block 404 to descend. Then, through the connection of the connecting rod 402, the second piston 401 is driven to descend, so that the exhaust groove 309 communicates with the rectangular ring cavity 307. The positive pressure in the rectangular ring cavity 307 blows air upward through the exhaust groove 309, thereby cleaning the cleaned brush bristles 203. When the second piston 401 moves downward, it compresses the first spring 408. Until the second inclined surface 407 separates from the extrusion block 406, under the elastic action of the first spring 408, the second piston 401 can be driven to move upward automatically, so that the exhaust groove 309 is no longer in communication with the rectangular ring cavity 307, making the inside of the rectangular ring cavity 307 in a positive pressure state.

Under the connection of the vertical rod 604, the second gear 606 is driven to move upward. Then, under the meshing cooperation of the second gear 606 and the third rack 607, the lifting rod 602 is driven to move upward. The upward movement of the lifting rod 602 drives the activity bar 501 to move upward. The upward movement of the activity bar 501 drives the comb teeth 502 to move upward. Thus, the bristles 203 can be cleaned by the upward movement of the comb teeth 502. Among them, through the fixed setting of the second rack 603 and the movable setting of the third rack 607, the upward movement of the second gear 606 can drive the lifting rod 602 to move upward by a double distance, so that the comb teeth 502 have enough upward height to comb the bristles 203.

[0049] The present invention also provides a use method of a coal separation machine, including the following steps:

[0050] Step 1: After the coal material enters the frame body 101, it is moved and conveyed through the conveying component. Then, the visual detection head 103 works to visually detect the coal material on the conveying component. When gangue is detected, the telescopic cylinder 108 works to drive the push plate 105 to move. The push plate 105 pushes the gangue on the conveying component out and discharges it from the frame body 101 through the chute 106. The remaining coal material continues to move through the conveying component;

[0051] Step 2: When cleaning the lens of the visual detection head 103, the servo motor 710 works to drive the first rotating rod 707 to rotate forward. The rotation of the first rotating rod 707 drives the first bevel gear 708 to rotate. The rotation of the first bevel gear 708 drives the engaged second bevel gear 709 to rotate. The rotation of the second bevel gear 709 drives the lead screw 702 to rotate. The rotation of the lead screw 702 can drive the slider 703 to move. The movement of the slider 703 drives the movable plate 201 to move. The movement of the movable plate 201 drives the square frame 202 to move. The movement of the square frame 202 drives the brush hair 203 to move until the brush hair 203 contacts the lens of the visual detection head 103 for cleaning;

[0052] Step 3: While the movable plate 201 moves, it will drive the first gear 312 to move. While the first gear 312 moves, it cooperates with the first rack 313 to drive the first gear 312 to rotate. Then, under the connection of the connecting rod 314, the first piston 302 moves back and forth inside the connection cavity 301. Thus, under the cooperation of the second one-way valve 306 and the first one-way valve 304, and under the connection of the connection groove 308, the rectangular ring cavity 307 continuously intakes air, making the inside of the rectangular ring cavity 307 in a positive pressure state. While the square frame 202 moves, it drives the first connecting block 404 to move until the first inclined surface 405 contacts the second inclined surface 407, causing the second inclined surface 407 to squeeze the first inclined surface 405, making the first connecting block 404 descend. Then, through the connection of the connecting rod 402, it drives the second piston 401 to descend, so that the exhaust groove 309 communicates with the rectangular ring cavity 307, and the positive pressure in the rectangular ring cavity 307 blows air upward through the exhaust groove 309, thereby cleaning the bristles 203 after cleaning;

[0053] Step 4: While the second inclined surface 407 squeezes the first inclined surface 405, the fourth inclined surface 505 will squeeze the third inclined surface 504, causing the second connecting block 503 to move upward. Under the connection of the vertical rod 604, it drives the second gear 606 to move upward. Then, under the meshing cooperation of the second gear 606 and the third rack 607, the lifting rod 602 moves upward. The upward movement of the lifting rod 602 drives the movable strip 501 to move upward, and the upward movement of the movable strip 501 drives the comb teeth 502 to move upward, so that the bristles 203 can be cleaned by the upward movement of the comb teeth 502;

[0054] Step 5: While the first rotating rod 707 rotates forward, it will drive the second synchronous wheel 806 to rotate. Then, under the connection of the synchronous belt 807, it drives the first synchronous wheel 805 to rotate, thereby driving the second rotating rod 802 to rotate. The rotation of the second rotating rod 802 drives the fan blade 803 to rotate forward. The forward-rotating fan blade 803 will generate a negative pressure suction below the fan blade 803, thereby sucking the dust combed off the bristles 203 by the comb teeth 502.
