Description

Technical Field

[0001] The invention relates to the technical field of dust reduction and suppression, and in particular to a dust reduction and suppression system for ore crushing and separation. Background Art

[0002] During the production process, ore is crushed in a crusher and then sorted. During the crushing, screening, and transportation of ore, the spread of high-concentration dust seriously pollutes the working environment, endangering equipment operation and personnel health. Therefore, dust reduction and suppression systems are required during the ore crushing and sorting process.

[0003] Authorization announcement number CN115999711B discloses an ore homogenizing crushing and sorting device for on-site processing of minerals. The present invention relates to the field of ore processing technology, specifically to an ore homogenizing crushing and sorting device for on-site processing of minerals, the ore homogenizing crushing and sorting device comprises a support frame, a feed frame, a crushing mechanism, a drive motor, a feeding mechanism, a sorting mechanism and a finished product box, the crushing mechanism and the drive motor are both arranged above the support frame, and the sorting mechanism is arranged on the outside of the support frame. Compared with the current ore homogenizing crushing and sorting device, the present invention is provided with a conversion component and a separation component. Through the conversion component and the separation component, on the one hand, the ore can contact with the flexible pad, thereby reducing the kinetic energy of the ore, and on the other hand, it can intercept the dust generated during crushing. The present invention is provided with There are a discharge chute and a movable plate, which on the one hand prevent the crushed ore from adhering to the inner wall of the discharge rack and the outer wall of the crushing component; on the other hand, when the filter hole at the lower end of the crushing component is blocked, it can automatically clean. The separation component in this invention has the function of one-way air intake and one-way exhaust. During the air intake process, the dust can be sucked into the circulation rack for collection, reducing the degree of dust dispersion and ensuring the health of the workers. However, in this way, the air intake and exhaust are used alternately, so the dust reduction effect is limited and the efficiency is low. In addition, the dust reduction is only carried out on the feed port of the crushing mechanism. In the ore processing process, dust will not only be generated on the feed port of the crushing mechanism, but a large amount of dust will also be generated during the discharge, including sorting and discharge. This dust will accumulate inside the device, thereby reducing the service life of the device. Summary of the Invention

[0055] See also Figure 1-Figure 3 The present invention provides an embodiment: a dust reduction and suppression system for ore crushing and sorting, comprising: a crusher 10, a discharge port at the bottom of the crusher 10 dropping the crushed ore onto a conveyor 20 through a discharge cover 30, the conveyor 20 being able to convey the crushed ore to the interior of a sorting mechanism 50 fixed at an output end, dust reduction and suppression being performed at the feed of the crusher 10, the conveyor 20, and the sorting mechanism 50 by a dust reduction mechanism 40, the dust reduction mechanism 40 including a dust suction component 41 and a dust collection component 42;

[0056] It should be noted that the ore can enter the crusher 10 through the feed port at the top of the crusher 10 for crushing. After the ore is crushed, it can fall onto the conveyor 20 through the discharge cover 30 at the bottom of the discharge port of the crusher 10. When the conveyor 20 transports the ore to the sorting mechanism 50, it can be sorted. During the process of crushing, transporting and sorting, the ore can be dusted by the dust collection component 41 on the dust reduction mechanism 40. After dust collection, the dust collection component 41 will transport the dust to the dust collection component 42 for collection.

[0057] like Figure 1-Figure 3 As shown, the dust collection assembly 41 includes a crushing dust collection pipe 411, a conveying dust collection pipe 412, and a sorting dust collection pipe 414. The crushing dust collection pipe 411 is installed on the top of the feed port of the crusher 10, the conveying dust collection pipe 412 is installed on the side of the discharge cover 30, and at least four groups of sorting dust collection pipes 414 are installed at equal distances inside the sorting mechanism 50. The crushing dust collection pipe 411, the conveying dust collection pipe 412, and the sorting dust collection pipe 414 can respectively collect dust raised by the ore when it falls into the crusher 10, the conveyor 20, and the sorting mechanism 50, and transport it to the inside of the dust collection assembly 42;

[0058] It can be imagined that the ore can enter the crusher 10 through the feed port at the top of the crusher 10 for crushing. Dust will be generated when the ore is inside the crusher 10 and when it is crushed, and the dust will be collected through the crushing dust suction pipe 411. After the ore is crushed, it can fall onto the conveyor 20 through the discharge cover 30 at the bottom of the discharge port of the crusher 10. The dust generated by the crushed ore when it falls can be collected through the conveying dust suction pipe 412. When the conveyor 20 transports the ore to the sorting mechanism 50, it can be sorted. The dust generated during the ore sorting can be collected by the sorting dust suction pipe 414. The crushing dust suction pipe 411, the conveying dust suction pipe 412 and the sorting dust suction pipe 414 absorb the dust and transport it to the dust collecting component 42 for collection.

[0059] like Figure 1 and Figure 3-Figure 7 As shown, the dust collecting assembly 42 includes a first filter box 421, a second filter box 422, a second fan 423, a conversion structure 424 and an air outlet cavity 427. The first filter box 421 is fixedly mounted on the bottom of the conveyor 20. A second filter box 422 is fixedly mounted on the bottom of the first filter box 421. An air outlet cavity 427 connected to the second filter box 422 is installed inside the first filter box 421. A second fan 423 is installed on one side of the first filter box 421 close to the air outlet cavity 427 to pump dust into the first filter box 421 or the second filter box 422 for filtration under negative pressure. The first filter box A conversion structure 424 is fixedly installed on the top of 421. When the conversion structure 424 moves horizontally toward the air outlet chamber 427 to a specified position, the first filter box 421 and the air outlet chamber 427 are closed, and the connection between the first filter box 421 and the second filter box 422 is opened, so that dust can enter the second filter box 422 through the connection and be filtered. When the conversion structure 424 moves horizontally toward the opposite direction of the air outlet chamber 427 to a specified position, the first filter box 421 and the air outlet chamber 427 are opened, and the connection between the first filter box 421 and the second filter box 422 is closed, so that dust can be filtered in the first filter box 421.

[0060] It is worth noting that when dust enters the first filter box 421, the second fan 423 can work to allow the dust to flow inside the first filter box 421. When the dust flows, the first filter box 421 can filter the dust through components. After the dust is filtered, the air can enter the air outlet cavity 427 and be discharged through the second fan 423. When more and more dust is filtered inside the first filter box 421, the wind speed inside the first filter box 421 will also decrease. When the wind speed inside the first filter box 421 is lower than the specified value, the conversion structure 424 can work to close the first filter box 421 and the air outlet cavity 427. The first filter box 421 and the second filter box When the connection 422 is opened, dust can enter the second filter box 422 through the connection between the first filter box 421 and the second filter box 422 for filtration, and the dust-filtered air can enter the air outlet cavity 427 and be discharged through the second fan 423. When more and more dust is filtered inside the second filter box 422, the wind speed inside the second filter box 422 will also decrease. When the wind speed inside the second filter box 422 is lower than the specified value, the conversion structure 424 can open the first filter box 421 and the air outlet cavity 427 and close the connection between the first filter box 421 and the second filter box 422, so that dust can be filtered in the first filter box 421.

[0061] like Figures 1-6 As shown, the dust collection assembly 41 also includes a protective cover 413, a conveying pipe 415 and a first fan 416. The protective cover 413 is an inverted trapezoidal shell. The upper edge of the protective cover 413 is fixedly mounted on the inner wall of the unloading cover 30 near the conveying dust collection pipe 412. The unloading cover 30 can protect the conveying dust collection pipe 412 when the ore falls. The crushing dust collection pipe 411, the conveying dust collection pipe 412 and the sorting dust collection pipe 414 are all connected to one end of the conveying pipe 415 for conveying dust to the inside of the first filter box 421. The other end of the conveying pipe 415 is connected to the side of the first filter box 421 away from the first fan 416. The first fan 416 is installed on the conveying pipe 415. The first fan 416 can adjust the suction force according to the different positions of the crushing dust collection pipe 411, the conveying dust collection pipe 412 and the sorting dust collection pipe 414;

[0062] It can be understood that when the ore falls, the protective cover 413 can protect the conveying dust suction pipe 412 through its own trapezoidal shape, and the operation of the first fan 416 can generate negative pressure inside the conveying pipe 415 and the crushing dust suction pipe 411, the conveying dust suction pipe 412, and the sorting dust suction pipe 414, so as to absorb the dust generated when the ore falls. Since the crushing dust suction pipe 411, the conveying dust suction pipe 412 and the sorting dust suction pipe 414 are located at different positions, the required suction force is also different. The suction force of the crushing dust suction pipe 411, the conveying dust suction pipe 412 and the sorting dust suction pipe 414 can be increased or decreased by adjusting the speed of the first fan 416. After being sucked in, the dust can enter the interior of the conveying pipe 415, and the conveying pipe 415 can transport the dust to the interior of the first filter box 421.

[0063] like Figure 1 、 Figure 3-Figure 7 As shown, the dust collection assembly 42 further includes a cleaning structure 425 and a collection structure 426. The cleaning structure 425 is installed throughout the interior of the first filter box 421. The cleaning structure 425 can vibrate and clean the dust inside the first filter box 421 and the second filter box 422 respectively by rotating. A collection structure 426 is installed on the lower inner side of the second filter box 422. The collection structure 426 can collect the dust that is shaken off.

[0064] It should be noted that when the cleaning structure 425 is working, the dust inside the first filter box 421 and the second filter box 422 can be vibrated and cleaned, and the dust inside the first filter box 421 and the second filter box 422 will fall into the collection structure 426 inside the second filter box 422 after vibration cleaning.

[0065] like Figure 3-Figure 6 As shown, the first filter box 421 includes a first filter 4211 and an air outlet 4212. The first filter box 421 is provided with the first filter 4211 inside. The air outlet 4212 is formed through one side of the first filter box 421 close to the air outlet cavity 427. The first filter 4211 can filter dust inside the first filter box 421. After being filtered, the dust can enter the air outlet cavity 427 through the air outlet 4212.

[0066] It is worth noting that when dust enters the first filter box 421, the second fan 423 can be used to move the dust from the first filter box 421 to the air outlet chamber 427. When the dust flows in the first filter box 421, the first filter 4211 can filter the dust. After the dust is filtered, the air can enter the air outlet chamber 427 through the air outlet 4212.

[0067] like Figure 3-Figure 7As shown, the second filter box 422 includes a second filter screen 4222 and an air inlet 4221. The second filter screen 4222 is movably installed on the bottom of the first filter box 421 near the air outlet cavity 427 through an assembly slot. The first filter box 421 is provided with an air inlet 4221 running through the bottom near the first filter screen 4211. When the air inlet 4221 is opened, dust inside the first filter box 421 will enter the second filter box 422 through the air inlet 4221. After the dust enters the second filter box 422, it can be filtered by the second filter screen 4222.

[0068] It should be noted that dust can enter the interior of the second filter box 422 through the air inlet 4221. When the second fan 423 is working, the dust moves from the inside of the second filter box 422 to the air outlet chamber 427. When the dust enters the air outlet chamber 427, the second filter 4222 can filter the dust. After the dust is filtered, the air can enter the air outlet chamber 427.

[0069] like Figure 3-Figure 7 As shown, the conversion structure 424 includes a mounting frame 4241, a rack 4242 and a gear 4243. The mounting frame 4241 is fixedly installed on the inner top of the first filter box 421. The interior of the mounting frame 4241 is movably installed with a rack 4242 through an assembly slot. One end of the rack 4242 is connected to the first filter screen 4211. The interior of the mounting frame 4241 is rotatably installed with a gear 4243 that matches the rack 4242 through the assembly slot. A driving part is installed at the center of the gear 4243 through a rotating shaft. Rotating the gear 4243 can drive the rack 4242 to move horizontally in the assembly slot of the mounting frame 4241.

[0070] It can be imagined that the driving part can drive the gear 4243 to rotate in the assembly groove of the mounting frame 4241. When the gear 4243 rotates, it can drive the rack 4242 to move horizontally in the assembly groove of the mounting frame 4241. When the rack 4242 moves horizontally, it can drive the first filter 4211 to move. When the first filter 4211 moves to the designated position, it will enter the interior of the second filter box 422 for filtering.

[0071] like Figure 3-Figure 7As shown, the conversion structure 424 also includes a movable cover 4244, a closing plate 4245 and a wind speed sensor 4246. The outer side of the first filter 4211 is sleeved with the movable cover 4244, and the movable cover 4244 moves horizontally inside the first filter box 421. The other end of the rack 4242 is fixedly installed with a closing plate 4245 that matches the air outlet 4212. The first filter box 421 is close to the mounting bracket 4241. The bottom of the inner side and the bottom of the outer surface are both installed with wind speed sensors 4246. The two wind speed sensors 4246 can The wind speed inside the first filter box 421 and the second filter box 422 are monitored respectively. When the wind speed inside the first filter box 421 is lower than a specified value, the rack 4242 moves horizontally to drive the closing plate 4245 to move to close the air outlet 4212, and the movable cover 4244 moves to open the air inlet 4221. When the wind speed inside the second filter box 422 is lower than a specified value, the rack 4242 moves horizontally to drive the closing plate 4245 to move to open the air outlet 4212, and the movable cover 4244 moves to open the air inlet 4221.

[0072] It is worth noting that as the dust on the surface of the first filter 4211 gradually increases, the wind speed inside the first filter box 421 will gradually decrease. When the wind speed sensor 4246 detects that the wind speed inside the first filter box 421 is lower than the specified value, it will send an instruction to the driving part of the gear 4243 to work. When the driving part is working, it can drive the rack 4242 to move horizontally in the assembly groove of the mounting frame 4241 through the gear 4243. When the rack 4242 moves horizontally, it can drive the closing plate 4245 and the movable cover 4244 to approach the air outlet 4212. When the closing plate 4245 closes the air outlet 4212, the movable cover 4244 will open the air inlet 4221 and close the air outlet 4212. After the air inlet 4221 is closed and opened, dust will enter the second filter box 422 through the air inlet 4221 and be filtered through the second filter screen 4222. After the dust enters the second filter box 422, it will drive the wind speed sensor 4246 inside the second filter box 422 to rotate. When the dust on the surface of the second filter screen 4222 gradually increases, the wind speed inside the second filter box 422 will be reduced. When the wind speed sensor 4246 detects that the wind speed inside the second filter box 422 is lower than the specified value, it will send an instruction to the driving part of the gear 4243 to work. When the gear 4243 rotates, it will drive the closing plate 4245 to open the air outlet 4212 and the movable cover 4244 to close the air inlet 4221 through the rack 4242.

[0073] like Figure 3-Figure 7As shown, the cleaning structure 425 includes a transmission rod 4251, a rotating plate 4253, a first protrusion 4254 and a first elastic member 4255. The transmission rod 4251 is rotatably installed on the side of the first filter box 421 close to the second fan 423. One end of the transmission rod 4251 is driven by a driving member, and the other end of the transmission rod 4251 passes through the inner side of the air outlet cavity 427 and is fixedly installed with a rotating plate 4253. The first protrusion is installed on both the rotating plate 4253 and the first filter screen 4211. 4254, the first filter screen 4211 is connected to the rack 4242 and the movable cover 4244 via a first elastic member 4255. Rotating the transmission rod 4251 can drive the rotating plate 4253 to rotate so that the first protrusion 4254 on the surface collides with the first protrusion 4254 on the first filter screen 4211. When the first protrusion 4254 on the first filter screen 4211 is collided, the first elastic member 4255 can cause the first filter screen 4211 to vibrate, thereby cleaning the dust.

[0074] It can be understood that when the movable cover 4244 moves toward the air outlet 4212, it drives the first protrusion 4254 on the surface of the first filter 4211 to move toward the first protrusion 4254 on the rotating plate 4253. When the two first protrusions 4254 move to the designated position, the driving part at one end of the transmission rod 4251 works to drive the transmission rod 4251 to rotate inside the first filter box 421. When the transmission rod 4251 rotates, it can drive the rotating plate 4253 at the end to rotate. When the rotating plate 4253 rotates, it can drive the first protrusion 4254 to rotate. When the first protrusion 4254 rotates, it will press the first filter 4211 The first protrusion 4254 on the surface is squeezed and collided, and the first protrusion 4254 on the surface of the first filter 4211 pushes the first filter 4211 when it is squeezed and collided. The first filter 4211 can stretch the first elastic member 4255 when it is pushed. When the two first protrusions 4254 are away from each other, the first filter 4211 can be reset by the first elastic member 4255. This reciprocating process can make the first filter 4211 vibrate rapidly. When the first filter 4211 vibrates, it can shake off the dust on the surface. After the dust is shaken off, it will fall into the collection structure 426 inside the second filter box 422 through the air outlet 4212.

[0075] like Figure 3-Figure 6As shown, the cleaning structure 425 also includes a transmission sleeve 4252, a second protrusion 4256 and a second elastic member 4257. The outer surface of the transmission rod 4251 is axially movable with the transmission sleeve 4252. The outer surface of the transmission sleeve 4252 passes through the air outlet cavity 427. One end of the transmission sleeve 4252 is installed at the end of the movable cover 4244 through a bearing seat. The other end of the transmission sleeve 4252 and the second filter 4222 are both installed with a second protrusion 4256. The second filter 4222 The top portion is connected to the assembly groove at the bottom of the first filter box 421 via a second elastic member 4257. Rotating the transmission rod 4251 drives the transmission sleeve 4252 to rotate. The rotation of the transmission sleeve 4252 drives the second protrusion 4256 on the surface to collide with the second protrusion 4256 on the second filter screen 4222. When the second protrusion 4256 on the second filter screen 4222 is collided, the second elastic member 4257 causes the second filter screen 4222 to vibrate, thereby cleaning the dust.

[0076] It should be noted that when the movable cover 4244 moves away from the air outlet 4212, it can drive the transmission sleeve 4252 to move axially on the transmission rod 4251 through the bearing seat. When the transmission rod 4251 moves, it can drive the second protrusion 4256 at the end to move toward the second protrusion 4256 on the second filter 4222. When the movable cover 4244 closes the air inlet 4221, the transmission sleeve 4252 will drive the second protrusion 4256 to move to the side of the second protrusion 4256 on the second filter 4222. The rotation of the transmission rod 4251 will drive the transmission sleeve 4252 on the surface to rotate. When the transmission sleeve 4252 rotates, The second protrusion 4256 on the surface is driven to squeeze and collide with the second protrusion 4256 on the second filter 4222. When the second protrusion 4256 on the second filter 4222 is squeezed and collided, the second filter 4222 is pushed. When the second filter 4222 is pushed, the second elastic member 4257 can be stretched. When the two first protrusions 4254 are away from each other, the second filter 4222 can be reset by the second elastic member 4257. This reciprocating movement can make the second filter 4222 vibrate rapidly. When the second filter 4222 vibrates, the dust on the surface can be shaken off, and the dust will fall into the collection structure 426 after being shaken off.

[0077] like Figure 3-Figure 7As shown, the collection structure 426 includes an isolation fence 4261, a closing fence 4262, bolts 4263 and a collection box 4264. The isolation fence 4261 is fixedly installed at the middle position inside the second filter box 422. A plurality of triangular isolation rods are provided on the isolation fence 4261. Ash discharge grooves are provided between the isolation rods. The width of the ash discharge grooves is smaller than the width of the isolation rods. The second filter box 422 is movably connected to the inner side of the isolation fence 4261 near the isolation fence 4262. The closing fence 4262 is provided with a closing rod. Ash discharge grooves are provided between the closing rods. One end of a bolt 4263 is rotatably mounted on one side, and the other end of the bolt 4263 is threadedly inserted into the inner side of the second filter box 422. A collection box 4264 is movably mounted on the side of the second filter box 422 near the bolt 4263. The isolation fence 4261 and the closing fence 4262 can discharge dust into the interior of the collection box 4264 through the dust discharge chute. Rotating the bolt 4263 can push the closing fence 4262 to move horizontally inside the second filter box 422. The closing rod on the closing fence 4262 moves to the bottom of the dust discharge chute of the isolation fence 4261 to close it.

[0078] It should be noted that when the dust falls, it will fall into the collection box 4264 through the dust discharge trough on the isolation fence 4261 and the closing fence 4262. When the dust inside the collection box 4264 is full, the bolt 4263 can be rotated. When the bolt 4263 is rotated, it can slide on the second filter box 422 through the threaded hole. The end of the bolt 4263 can be rotated on the side of the closing fence 4262. When the end of the bolt 4263 rotates, it pushes the closing fence 4262 to slide inside the second filter box 422. When the closing fence 4262 slides, it drives the closing rod to close the isolation fence 4261. The ash discharge chute is closed. After the ash discharge chute on the isolation fence 4261 is closed, the dust will temporarily accumulate on the triangular isolation rod of the isolation fence 4261. At this time, the collection box 4264 can be taken out to recycle the dust, so that the equipment can remove the dust without stopping. After the dust is taken out, the collection box 4264 is put back into the second filter box 422. After the collection box 4264 is put back, the bolt 4263 is rotated to drive the ash discharge chute on the closed fence 4262 to dock with the ash discharge chute on the isolation fence 4261. At this time, the dust can slide through the inclined surface of the triangular isolation rod on the isolation fence 4261 into the collection box 4264.
