[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. After mining, the coal needs to be transported to power plants by transportation equipment, and then the coal blocks are transported by coal conveyor belts in the power plants. Since the mined coal blocks are large and the space in the power plants is limited, it is not convenient to transport large coal blocks in the power plants. They need to be crushed and divided into several evenly sized coal blocks before they can be transported.

[0003] At present, a lot of coal fragments will be produced after the coal blocks are crushed. These fragments may be scattered during transportation. Since these fragments still have heat, the dust generated by the scattered fragments will also pose a risk of dust explosion. Therefore, the coal blocks need to be filtered and collected before transportation. Summary of the Invention

[0027] Example 1

[0028] Since the coal fragments still have heat, the dust generated by the scattered fragments will also pose a risk of dust explosion. Therefore, the coal blocks need to be filtered and collected before transportation. Since the uses of fragments of different particle sizes are very different, if only the fragments are initially filtered and collected, this classification process cannot produce greater utilization value. In order to solve this problem, refer to Figures 1-6 , this embodiment proposes a dust collection device with a multi-layer filtering function, including an equipment housing 1, a feeding chute 5 is provided on the equipment housing 1, a filter drum 6 is rotatably installed on the equipment housing 1, a collecting trough 11 is provided on the equipment housing 1, and a discharge port 12 communicating with the interior of the equipment housing 1 is provided on the collection trough 11. The crushed coal blocks and debris are put into the feeding chute 5, and the coal blocks and debris enter the rotating filter drum 6 so that the debris falls into the collecting chute 11 and is discharged through the discharge port 12. The coal blocks will fall onto the conveyor belt along the feeding chute 5, and a separation plate 13 is rotatably installed on the equipment housing 1. A plurality of groups of filter holes 14 are evenly arranged on the separation plate 13 to classify and process the debris;

[0029] A separation device 2 for separating coal mine debris is installed on the equipment housing 1, a cleaning device 3 for preventing the filter hole 14 from being blocked is installed on the equipment housing 1, and a driving device 4 is installed on the equipment housing 1. By starting the driving device 4, the separation device 2 moves and the separation plate 13 is driven to rotate up and down, and the cleaning device 3 moves along the bottom of the separation plate 13. The separation plate 13 rotates up and down to drive the debris to roll, which facilitates the filtering and classification of the debris.

[0030] The separation device 2 includes two groups of sliding grooves 201 provided on the separation plate 13, each group of sliding grooves 201 is fixedly installed with a fixed rod 202, and each group of sliding grooves 201 is slidably installed with a support plate 203 slidably connected to the fixed rod 202. The fixed rod 202 makes the movement of the support plate 203 more stable, and a rotating block 204 is rotatably installed on the support plate 203, and a roller 205 is rotatably installed on the rotating block 204. The roller 205 can roll on the stop platform 206, the first slope 207 and the second slope 208. The separation device 2 also includes two groups of stop platforms 206 provided on the equipment housing 1, two groups of No. 1 slopes 207 connected to the stop platform 206 are provided on the equipment housing 1, and two groups of No. 1 slopes 207 connected to the stop platform are provided on the equipment housing 1. 206 is connected to the second slope 208, and a vibration motor 209 is fixedly installed on the separation plate 13. The vibration motor 209 makes the bottom of the separation plate 13 vibrate to avoid the accumulation of debris on the separation plate 13. The separation device 2 also includes a fixed block 210 fixedly installed on the rotating block 204. Two groups of limit grooves 211 slidingly connected to the fixed block 210 are provided on the device housing 1. A reciprocating screw rod 212 is rotatably installed on each group of limit grooves 211, and a limit block 213 threadedly connected to the reciprocating screw rod 212 is slidably installed on each group of limit grooves 211. A limit rod 214 slidingly connected to the fixed block 210 is fixedly installed on the limit block 213. The driving device 4 includes a driving motor 401 fixedly installed on the device housing 1. A rotating column 402 fixedly connected to the output end of the drive motor 401 is rotatably installed on the outer shell 1, and two groups of worms 403 are fixedly installed on the rotating column 402. A worm wheel 404 meshing with the worm 403 is fixedly installed on each group of reciprocating screws 212. A No. 1 collecting box 601 is plugged into the equipment housing 1, and a No. 2 collecting box 602 is plugged into the equipment housing 1. The No. 1 collecting box 601 is used to collect debris filtered through the filter hole 14, and the No. 2 collecting box 602 is used to collect larger debris. When the debris falls onto the separation plate 13 through the discharge port 12, the drive motor 401 is started to make the two groups of worms 403 on the rotating column 402 rotate at the same time. Under the action of the worm wheel 404, the worm 403 rotates, causing the reciprocating screw 212 to move in a direction opposite to the original direction. The limiting block 213 rotates in the limiting block 213, so that the limiting block 213 drives the fixed block 210 connected to the limiting rod 214 to move in the limiting groove 211. The movement of the fixed block 210 drives the rotating block 204 and the support plate 203 to move, and causes the roller 205 to roll on the stop platform 206, the first slope 207 and the second slope 208. When the roller 205 rolls on the second slope 208, the rotating block 204 and the support plate 203 rotate and drive the separation plate 13 connected to the support plate 203 to rotate downward, which not only facilitates the collection of debris for classification and processing, but also makes the debris at the open end of the separation plate 13 roll back for secondary filtration, thereby improving the filtration effect. When the roller 205 rolls on the first slope 207, the separation plate 13 rotates upward.The debris that has not been filtered through the filter hole 14 is poured into the first collection box 601, thereby avoiding the risk of dust explosion caused by the dust generated by the scattered debris.

[0031] Example 2

[0032] Since the filter holes on the separation plate may be clogged, this will reduce the filtering speed and effect of the coal debris. In order to solve this problem, refer to Figures 1-6 The cleaning device 3 includes a toothed plate 301 fixedly mounted on one side of the separation plate 13, a gear 302 meshing with the toothed plate 301 is rotatably mounted on one set of support plates 203, a fixed shaft 303 is fixedly mounted on the gear 302, and a first helical tooth 304 is fixedly mounted on the fixed shaft 303. The cleaning device 3 also includes a rotating rod 305 rotatably mounted between the two sets of support plates 203, a brush cylinder 306 is fixedly mounted on the rotating rod 305, and one end of the rotating rod 305 is fixedly mounted with a brush that meshes with the first helical tooth 304. The second bevel gear 307, under the action of the tooth plate 301, the support plate 203 moves to make the gear 302 rotate, the rotation of the gear 302 drives the first bevel gear 304 connected to the fixed shaft 303 to rotate, the rotation of the first bevel gear 304 drives the rotating rod 305 connected to the second bevel gear 307 to rotate, the rotation of the rotating rod 305 drives the brush cylinder 306 to rotate, and the filter hole 14 at the bottom of the separation plate 13 can be cleaned, avoiding the situation that the filter hole 14 on the separation plate 13 is blocked and reduces the filtering speed and effect of the coal block debris.

[0033] Working principle: When the debris falls onto the separation plate 13 through the discharge port 12, the drive motor 401 is started to make the two sets of worms 403 on the rotating column 402 rotate at the same time. Under the action of the worm gear 404, the worm 403 rotates to make the reciprocating screw 212 rotate in the limit block 213, so that the limit block 213 drives the fixed block 210 connected to the limit rod 214 to move in the limit groove 211. The movement of the fixed block 210 drives the rotating block 204 and the support plate 203 to move, and makes the roller 205 roll on the stop table 206, the No. 1 slope 207 and the No. 2 slope 208. When the roller 205 rolls on the No. 2 slope 208, the rotating block 204 and the support plate 203 rotate and drive the separation connected to the support plate 203 The plate 13 rotates downward, which not only facilitates the collection of debris for classification and processing, but also allows the debris at the open end of the separation plate 13 to roll back for secondary filtration, thereby improving the filtration effect. When the roller 205 rolls on the No. 1 slope 207, the separation plate 13 rotates upward, and the debris that has not passed through the filter hole 14 is poured into the No. 1 collection box 601. Under the action of the tooth plate 301, the support plate 203 moves to cause the gear 302 to rotate. The rotation of the gear 302 drives the No. 1 bevel gear 304 connected to the fixed shaft 303 to rotate. The rotation of the No. 1 bevel gear 304 drives the rotating rod 305 connected to the No. 2 bevel gear 307 to rotate. The rotation of the rotating rod 305 drives the brush cylinder 306 to rotate, and the filter hole 14 at the bottom of the separation plate 13 can be cleaned.
