Technical Field

[0001] This invention relates to the field of coal crushing technology, specifically to a coal crushing device and crushing method with sorting function. Background Technology

[0002] Coal crushing is the process of breaking raw coal down from its natural state into smaller particles or chunks, usually for easier handling, transportation, storage and combustion.

[0003] Patent publication number CN210410948U relates to a coal crushing device with a sorting function, including a crusher shell. An outer shell is fixedly connected to the outer surface of the crusher shell. Two support plates are fixedly installed on the left inner wall of the outer shell. Motors are fixedly connected to the upper surfaces of both support plates. A connecting rod 1 is fixedly connected to the bottom output shaft of the motor. A connecting rod 2 is movably connected to the lower right surface of the connecting rod 1. A screen plate is fixedly connected to the right side of the connecting rod 2. This coal crushing device with a sorting function achieves the sorting effect by having the motor drive the rotation of the connecting rod 1, which in turn drives the connecting rod 2 to reciprocate. The connecting rod 2 causes the upper screen plate to slide left and right in a chute via a slider. Smaller coal chunks and coal powder fall onto the lower screen plate, while larger coal chunks slide out from the sliding plate on the right side, thus achieving the sorting effect.

[0004] In the aforementioned patent, a motor drives the first connecting rod to rotate, which in turn drives the second connecting rod to reciprocate. The second connecting rod then drives the upper screen plate to slide left and right in the chute via a slider, achieving the screening effect. Smaller coal chunks and coal powder fall onto the lower screen plate, while larger coal chunks slide out from the right-side slide plate, thus achieving the sorting effect. However, during coal crushing, coal continuously enters the crushing device, causing coal to gradually accumulate at the crushing location. Excessive coal accumulation affects the crushing process, making it difficult to control the amount of coal entering the device when excessive accumulation occurs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a coal crushing device and crushing method with sorting function, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a coal crushing device with sorting function, comprising a device body, a limiting device, and a feeding device. A crushing frame and a feeding plate are fixedly installed on the top of the device body. An mounting plate is fixedly installed on the surface of the crushing frame, and a driving device is installed on the surface of the mounting plate. A crushing wheel is rotatably installed inside the crushing frame, and the crushing wheel is fixed to the output end of the driving device. A filter plate is fixedly installed inside the device body. The limiting device includes a guide plate, a baffle, a pressing rod, a pushing plate, and a locking rod. When too much coal accumulates on the crushing wheel, it will press against the guide plate. When the guide plate rotates downwards, it drives the pressing rod to rotate downwards. The downward rotation of the pressing rod pushes the baffle to rotate downwards, restricting the coal on the feed plate. As more coal accumulates on the crushing wheel, the downward movement of the pressing rod drives the pushing plate downwards, which in turn pushes the locking rod downwards. The guide plate is rotatably installed inside the crushing frame, the baffle is rotatably installed inside the feed plate, the pressing rod is fixedly installed on the top of the guide plate, and the pushing plate is fixedly installed on the surface of the pressing rod. The locking rod slides through the mounting plate to prevent excessive coal accumulation on the top of the crushing wheel from affecting coal crushing.

[0007] According to the above technical solution, a first torsion spring is provided between the guide plate and the crushing frame, a second torsion spring is provided between the baffle and the feed plate, and a first spring is provided between the locking rod and the mounting plate. The elastic force of the first torsion spring will push the guide plate to reset.

[0008] According to the above technical solution, the feeding device includes a diversion plate, a forked plate, an arc-shaped rod, and a triangular block. When the diversion plate rotates, it drives the arc-shaped rod to rotate. When the arc-shaped rod rotates, it contacts the triangular block, causing the arc-shaped rod to rotate and push the triangular block and the forked plate to rotate. When the forked plate rotates, it disperses the coal on the diversion plate. The diversion plate is rotatably installed on the top of the inner wall of the device body. A No. 3 torsion spring is provided between the diversion plate and the device body. The forked plate is rotatably installed on the top of the inner wall of the device body.

When the moving rod moves, it will drive the connecting... The rod and sealing plate move. When the sealing plate moves downward, it squeezes the water inside the hollow frame into the connecting frame. When the water pressure inside the connecting frame increases, the water pushes the opening rubber to deform. The deformation of the opening rubber opens the connecting frame, and the water inside the connecting frame is sprayed out from the spray plate. A water tank is fixedly installed on the outer wall of the device body. The water tank is connected to the hollow frame through a pipe. A one-way valve is installed inside the pipe. When passing through the one-way valve, the water in the water tank can only flow into the hollow frame. The water mist sprayed by the spray plate will have a dust suppression effect on the bottom of the filter plate, preventing coal dust from causing danger.

[0010] According to the above technical solution, it also includes a shaking device and a separation device. The shaking device is installed inside the main body of the device. The shaking device includes a bending rod, an elastic rod, a protrusion, and an arc-shaped block. When the bending rod rotates, it drives the elastic rod to rotate. When the elastic rod rotates, it drives the protrusion to move. When the protrusion moves, it will hit the arc-shaped block and the filter plate. After being hit, the filter plate will vibrate. The bending rod is fixedly installed at the bottom of the diversion plate, the elastic rod is fixedly installed on the surface of the bending rod, the protrusion is fixedly installed at the bottom of the elastic rod, and the arc-shaped block is fixedly installed at the top of the filter plate.

[0011] According to the above technical solution, a fixed frame is fixedly installed inside the device body, and an air jet plate is fixedly installed inside the device body. The fixed frame is connected to the inside of the air jet plate through a conveying pipe. A squeezing plate is slidably installed inside the fixed frame.

When the squeezing plate moves, it will squeeze the air inside the fixed frame and spray it out from the air jet plate through the conveying pipe. A No. 3 spring is set between the squeezing plate and the fixed frame. The gas sprayed out by the air jet plate will blow away the coal powder adhering to the surface of the coal block.

[0012] According to the above technical solution, the separation device includes a sliding rod, an inclined block, a scraper, and a contact rod. When the contact rod moves, it contacts the inclined block, causing the inclined block and the sliding rod to move. When the sliding rod moves, it drives the scraper to move. The sliding rod slides through the device body. A No. 4 spring is provided between the sliding rod and the device body. The inclined block is fixedly installed at the bottom of the sliding rod, the scraper is fixedly installed at the top of the sliding rod, and the contact rod is fixedly installed on the surface of the connecting rod to prevent wet coal powder from adhering to the bottom of the filter plate and affecting the coal sorting effect.

[0013] According to the above technical solution, a heating device is fixedly installed on the outer wall of the device body, a heat-conducting frame is fixedly installed on the surface of the sliding rod, a piston plate is slidably installed inside the heat-conducting frame, a linkage rod is fixedly installed on the surface of the piston plate, an air nozzle is fixedly installed on the top of the sliding rod, the interior of the sliding rod is hollow, and the sliding rod communicates with the air nozzle and the interior of the heat-conducting frame. When the heat-conducting frame moves, it will drive the piston plate and the linkage rod to move.

The piston plate will push the high-temperature air inside the heat-conducting frame to be ejected from the air nozzle. A No. 5 spring is provided between the piston plate and the heat-conducting frame. The ejected high-temperature air heats the coal powder at the bottom of the filter plate to prevent the damp coal powder from failing to detach from the filter plate.

[0014] A crushing method for a coal crushing device with sorting function includes:

[0015] Step 1: Coal is fed into the inside of the feed plate, and the coal inside the feed plate slides into the inside of the crushing frame;

[0016] Step 2: Start the drive unit, which drives the crushing wheel to rotate, and the rotating crushing wheel crushes the coal;

[0017] Step 3: Excessive coal buildup on top of the crusher wheel will press the guide plate downwards, causing it to rotate downwards. The downward rotation of the guide plate will cause the pressing rod to rotate downwards, which in turn will push the baffle to rotate downwards.

[0018] Step 4: Rotate the baffle downwards to reduce the speed at which coal on the feed plate enters the crushing frame.

[0019] This invention provides a coal crushing device and method with sorting function. It has the following beneficial effects:

[0020] (1) In this invention, the driving device drives the crushing wheel to rotate. When the crushing wheel rotates, it crushes the coal. When too much coal accumulates on the top of the crushing wheel, it will squeeze the guide plate. When the guide plate rotates downward, it will drive the pressing plate to press the baffle. When the baffle rotates downward, it will restrict the coal on the feed plate from entering the interior of the crushing frame, preventing the excessive accumulation of coal on the top of the crushing wheel from affecting the crushing of the coal. At the same time, when the guide plate rotates downward too much, the push plate will push the locking rod to move downward to restrict the crushing wheel from rotating, thus avoiding the accumulation of coal from affecting the driving device.

[0021] (2) In this invention, the broken coal will move to the diversion plate, and the falling coal will push the diversion plate to rotate and the arc rod to rotate. When the arc rod rotates, it will push the triangular block and the forked plate to rotate. When the forked plate rotates, it will break up the coal on the diversion plate, preventing the accumulated coal from moving to the filter plate. This will prevent the accumulated coal from reducing the filtration effect of the filter plate on the coal. At the same time, when the forked plate rotates, it will push the inclined block and the connecting rod to move downward. When the connecting rod moves downward, it will squeeze the water inside the hollow frame to be discharged from the spray plate. The water mist sprayed by the spray plate will have a dust suppression effect on the bottom of the filter plate, preventing coal dust from causing danger.

[0022] (3) In this invention, when the diversion plate rotates, it will drive the bending rod to rotate, and when the bending rod rotates, it will drive the elastic rod to rotate. When the bending rod rotates, it will drive the protrusion to hit the arc block and the filter plate, causing the filter plate to vibrate. The vibration of the filter plate can increase the effect of coal moving on the filter plate, and at the same time improve the effect of the filter plate on coal sorting. When the bending rod rotates, it will push the extrusion plate to move. The extrusion plate will squeeze the air inside the fixed frame and spray it out from the jet plate. The gas sprayed out by the jet plate will blow away the coal powder adhering to the surface of the coal block.

[0023] (4) In this invention, when the connecting rod moves, it will drive the contact rod to move. When the contact rod moves, it will push the inclined block and the sliding rod to move. When the sliding rod moves, it will drive the scraper to move. The scraper will scrape off the wet coal powder adhering to the bottom of the filter plate, preventing the wet coal powder from adhering to the bottom of the filter plate and affecting the coal sorting effect. When the sliding rod moves, the piston plate will squeeze the high-temperature air inside the heat-conducting frame and spray it out from the jet nozzle to heat the coal powder at the bottom of the filter plate, preventing the wet coal powder from being unable to detach from the filter plate.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-6One embodiment of the present invention is a coal crushing device with sorting function, comprising a device body 1, a limiting device, and a feeding device. A crushing frame 2 and a feeding plate 3 are fixedly installed on the top of the device body 1. An mounting plate 47 is fixedly installed on the surface of the crushing frame 2, and a driving device 41 is installed on the surface of the mounting plate 47. A crushing wheel 42 is rotatably installed inside the crushing frame 2, and the crushing wheel 42 is fixed to the output end of the driving device 41. A filter plate 49 is fixedly installed inside the device body 1. The limiting device includes a guide plate 43, a baffle 44, a pressing rod 45, a pushing plate 46, and a locking rod 48. When too much coal accumulates on the crushing wheel 42, it presses down on the guide plate 43. When rotated downwards, the pressing rod 45 rotates downwards, which in turn pushes the baffle 44 downwards. When the baffle 44 rotates downwards, it restricts the coal on the feed plate 3. As the coal on the crushing wheel 42 continues to increase, the pressing rod 45 moves downwards, which in turn pushes the push plate 46 downwards. The push plate 46 moves downwards, which in turn pushes the locking rod 48 downwards. The guide plate 43 is rotatably installed inside the crushing frame 2, and the baffle 44 is rotatably installed inside the feed plate 3. The pressing rod 45 is fixedly installed on the top of the guide plate 43, and the push plate 46 is fixedly installed on the surface of the pressing rod 45. The locking rod 48 slides through the mounting plate 47 to prevent excessive coal accumulation on the top of the crushing wheel 42 from affecting coal crushing.

[0034] A first torsion spring is provided between the guide plate 43 and the crushing frame 2, a second torsion spring is provided between the baffle 44 and the feed plate 3, and a first spring is provided between the locking rod 48 and the mounting plate 47. The elastic force of the first torsion spring will push the guide plate 43 to reset.

[0035] The feeding device includes a diversion plate 51, a forked plate 52, an arc-shaped rod 53, and a triangular block 54. When the diversion plate 51 rotates, it drives the arc-shaped rod 53 to rotate. When the arc-shaped rod 53 rotates, it contacts the triangular block 54, causing the arc-shaped rod 53 to rotate and push the triangular block 54 and the forked plate 52 to rotate. When the forked plate 52 rotates, it disperses the coal on the diversion plate 51. The diversion plate 51 is rotatably installed on the top of the inner wall of the device body 1. A No. 3 torsion spring is provided between the diversion plate 51 and the device body 1. The forked plate 52 is rotatably installed on the top of the inner wall of the device body 1. The arc-shaped rod 53 is fixedly installed on the surface of the diversion plate 51. The triangular block 54 is fixedly installed on the surface of the forked plate 52. An air suction device 81 is fixedly installed on the surface of the device body 1. An exhaust frame 82 is fixedly installed at the bottom of the air suction device 81. An exhaust plate 83 is fixedly installed inside the device body 1 to prevent the accumulated coal from moving to the filter plate 49 and to prevent the accumulated coal from reducing the filtration effect of the filter plate 49 on the coal.

[0036] An arc-shaped plate 59 is fixedly installed on the surface of the bifurcation plate 52. A moving rod 57 is slidably installed inside the device body 1. An inclined block 58 is fixedly installed at the bottom of the moving rod 57. A hollow frame 55 is fixedly installed inside the device body 1. A sealing plate 56 is fixedly installed on the inner wall of the hollow frame 55. The sealing plate 56 is fixed to the moving rod 57 via a connecting rod 510. A second spring is provided between the moving rod 57 and the device body 1. A connecting frame 511 is fixedly installed on the surface of the hollow frame 55. A spray plate 512 is fixedly installed on the surface of the connecting frame 511. An open rubber 513 is fixedly installed inside the connecting frame 511. When the moving rod 57 moves, it will drive the connecting rod 510 and the sealing plate 56 to move. When the sealing plate 56 moves downward, it squeezes the water inside the hollow frame 55 into the connecting frame 511. When the water pressure inside the connecting frame 511 increases, the water pushes the opening rubber 513 to deform. The deformation of the opening rubber 513 will open the connecting frame 511, and the water inside the connecting frame 511 will be sprayed out from the spray plate 512. A water tank 514 is fixedly installed on the outer wall of the device body 1. The water tank 514 is connected to the hollow frame 55 through a pipe. A one-way valve is installed inside the pipe. When passing through the one-way valve, the water inside the water tank 514 can only flow into the hollow frame 55. The water mist sprayed by the spray plate 512 will have a dust suppression effect on the bottom of the filter plate 49 to prevent coal dust from causing danger.

[0037] In this embodiment, during operation, coal rolls into the crushing frame 2 through the feed plate 3. The drive device 41 is activated, and when the drive device 41 is working, it drives the crushing wheel 42 to rotate. When the crushing wheel 42 rotates, it crushes the coal. When too much coal accumulates on the crushing wheel 42, it presses down the guide plate 43. When the guide plate 43 rotates downward, it drives the pressing rod 45 to rotate downward. When the pressing rod 45 rotates downward, it pushes the baffle 44 to rotate downward. When the baffle 44 rotates downward, it restricts the coal on the feed plate 3. When the coal on the crushing wheel 42 continues to increase, the pressing rod 45 moves downward, which drives the pushing plate 46 to move downward. When the pushing plate 46 moves downward, it pushes the locking rod 48 to move downward. When the locking rod 48 moves downward, it inserts into the interior of the drive device 41 to restrict the operation of the drive device 41, thereby shutting down the drive device 41 and the crushing wheel 42.

[0038] The broken coal falls onto the diversion plate 51, causing it to rotate. This rotation drives the arc-shaped rod 53 to rotate as well. The arc-shaped rod 53 then contacts the triangular block 54, causing it to rotate and thus pushing the triangular block 54 and the forked plate 52 to rotate as well. The rotation of the forked plate 52 breaks up the coal on the diversion plate 51. This rotation also drives the arc-shaped plate 59 to rotate, causing it to contact the inclined block 58. The rotation of the arc-shaped plate 59 then pushes the inclined block 58 and the moving rod 57 to move. When the moving rod 57 moves, it will drive the connecting rod 510 and the sealing plate 56 to move. When the sealing plate 56 moves downward, it will squeeze the water inside the hollow frame 55 into the interior of the connecting frame 511. When the water pressure inside the connecting frame 511 increases, the water will push the opening rubber 513 to deform. The deformation of the opening rubber 513 will open the connecting frame 511, and the water inside the connecting frame 511 will be sprayed out from the spray plate 512. The water sprayed out by the spray plate 512 will reduce dust at the bottom of the filter plate 49. When the suction device 81 is working, it will suck the dust generated during crushing into the interior of the device body 1.

[0039] Please see Figure 1-7 Based on the above embodiments, another embodiment of the present invention further includes a shaking device and a separation device. The shaking device is provided inside the device body 1. The shaking device includes a bending rod 61, an elastic rod 62, a protrusion 63, and an arc-shaped block 64. When the bending rod 61 rotates, it will drive the elastic rod 62 to rotate. When the elastic rod 62 rotates, it will drive the protrusion 63 to move. When the protrusion 63 moves, it will hit the arc-shaped block 64 and the filter plate 49. After the arc-shaped block 64 and the filter plate 49 are hit, the filter plate 49 will vibrate. The bending rod 61 is fixedly installed at the bottom of the diversion plate 51, the elastic rod 62 is fixedly installed on the surface of the bending rod 61, the protrusion 63 is fixedly installed at the bottom of the elastic rod 62, and the arc-shaped block 64 is fixedly installed at the top of the filter plate 49.

When the bending rod 61 moves, it will push the squeezing plate 67 to move. When the squeezing plate 67 moves, it will squeeze the air inside the fixed frame 65 and spray it out from the air jet plate 66 through the conveying pipe. A No. 3 spring is set between the squeezing plate 67 and the fixed frame 65. The gas sprayed out by the air jet plate 66 will blow away the coal powder adhering to the surface of the coal block.

[0041] The separation device includes a sliding rod 71, an inclined block 72, a scraper 73, and a contact rod 74. When the contact rod 74 moves, it contacts the inclined block 72, causing the inclined block 72 and the sliding rod 71 to move. When the sliding rod 71 moves, it drives the scraper 73 to move. The sliding rod 71 slides through the device body 1. A No. 4 spring is provided between the sliding rod 71 and the device body 1. The inclined block 72 is fixedly installed at the bottom of the sliding rod 71, the scraper 73 is fixedly installed at the top of the sliding rod 71, and the contact rod 74 is fixedly installed on the surface of the connecting rod 510 to prevent wet coal powder from adhering to the bottom of the filter plate 49 and affecting the coal separation effect.

[0042] A heating device 79 is fixedly installed on the outer wall of the main body 1. A heat-conducting frame 75 is fixedly installed on the surface of the sliding rod 71. A piston plate 76 is slidably installed inside the heat-conducting frame 75. A linkage rod 77 is fixedly installed on the surface of the piston plate 76. An air nozzle 78 is fixedly installed on the top of the sliding rod 71. The interior of the sliding rod 71 is hollow. The sliding rod 71 communicates with the interior of the air nozzle 78 and the heat-conducting frame 75. When the heat-conducting frame 75 moves, it will drive the piston plate 76 and the linkage rod 77 to move. When the linkage rod 77 contacts the connecting rod 510, the connecting rod 510 will push the linkage rod 77 and the piston plate 76 to move into the interior of the heat-conducting frame 75. The piston plate 76 will push the high-temperature air inside the heat-conducting frame 75 to be ejected from the air nozzle 78. A No. 5 spring is provided between the piston plate 76 and the heat-conducting frame 75. The ejected high-temperature air heats the coal powder at the bottom of the filter plate 49 to prevent the wet coal powder from failing to detach from the filter plate 49.

[0043] A crushing method for a coal crushing device with sorting function includes:

[0044] Step 1: Coal is fed into the inside of the feed plate 3, and the coal inside the feed plate 3 slides into the inside of the crushing frame 2;

[0045] Step 2: Start the drive device 41. The drive device 41 drives the crushing wheel 42 to rotate, and the crushing wheel 42 crushes the coal.

[0046] Step 3: Excessive coal accumulation on the top of the crushing wheel 42 will press the guide plate 43 to rotate downwards. The downward rotation of the guide plate 43 will drive the pressing rod 45 to rotate downwards, and the downward rotation of the pressing rod 45 will push the baffle 44 to rotate downwards.

[0047] Step 4: The baffle 44 rotates downward to reduce the speed at which the coal on the feed plate 3 enters the crushing frame 2.

[0048] In this embodiment, when the diversion plate 51 rotates, it will drive the bending rod 61 to rotate. When the bending rod 61 rotates, it will drive the elastic rod 62 to rotate. When the elastic rod 62 rotates, it will drive the protrusion 63 to move. When the protrusion 63 moves, it will hit the arc block 64 and the filter plate 49. After the arc block 64 and the filter plate 49 are hit, the filter plate 49 will vibrate. When the bending rod 61 moves, it will push the extrusion plate 67 to move. When the extrusion plate 67 moves, it will squeeze the air inside the fixed frame 65 and spray it out from the jet plate 66 through the delivery pipe.

[0049] When the connecting rod 510 moves, it drives the contact rod 74 to move. The contact rod 74 then contacts the inclined block 72, causing it to push the inclined block 72 and the sliding rod 71 to move. The sliding rod 71 then drives the scraper 73 to move, scraping away the damp coal at the bottom of the filter plate 49. The heating device 79 heats the sliding rod 71. After the contact rod 74 disengages from the inclined block 72, the fourth spring causes the sliding rod 71 to return to its original position. When the connecting rod 510 moves, it will drive the heat-conducting frame 75 to move. When the heat-conducting frame 75 moves, it will drive the piston plate 76 and the linkage rod 77 to move. When the linkage rod 77 contacts the connecting rod 510, the connecting rod 510 will push the linkage rod 77 and the piston plate 76 to move into the heat-conducting frame 75. The piston plate 76 will push the high-temperature air inside the heat-conducting frame 75 to be ejected from the jet nozzle 78. The high-temperature air ejected from the jet nozzle 78 will dry the damp coal at the bottom of the filter plate 49.
