Description

Technical Field

[0001] The invention relates to the technical field of magnesia-alumina-carbon brick processing and production, and in particular to a VOD ladle wall magnesia-alumina-carbon brick processing device for smelting ultrapure stainless steel. Background Art

[0002] VOD is also known as vacuum oxygen decarburization. In this type of refining equipment outside the furnace, the ladle containing molten steel from the converter or electric furnace is placed in a vacuum chamber, argon is blown from the air-permeable bricks at the bottom of the tank for stirring, and vacuum degassing is performed at the same time. Then oxygen is blown from the top to the molten steel for decarburization and ferroalloy is added. It is a method for producing low-carbon stainless steel with less hydrogen, oxygen and non-metallic inclusions. When the ladle used in VOD is injected with molten steel, the traditional ladle impact block is a flat surface that cannot disperse the impact force. Long-term impact easily causes the impact block to wear more and crack and reduce its service life. This product responds to customer needs and requires high-purity ferritic stainless steel with carbon + nitrogen ≤150~250×10-6. Therefore, the company's magnesium-aluminum-carbon bricks are not only required to be wear-resistant but also have a low carbon content. At present, the ladle is basically a composite furnace, that is, different parts use refractory materials of different materials. The permanent layer generally uses high-alumina castables or fired bricks, and also uses aluminum-magnesium materials; the working layer uses aluminum-magnesium materials of different grades and different grades of magnesium-carbon bricks and aluminum-magnesium-carbon bricks. In recent years, magnesium-aluminum-carbon bricks have also been used. In harsh environments such as high temperature and chemical corrosion, the surface of magnesium-aluminum-carbon bricks may corrode, and the surface may become loose, bubbling, and peeling, resulting in irregular shape or deformation, so that the working layer needs to be repaired and replaced in time. In order to make full use of raw material resources, it is imperative to recycle damaged magnesium-aluminum-carbon bricks.

[0003] However, in actual use, the inventors found that the recycled magnesium-aluminum-carbon bricks need to be crushed in the early stage of processing, so that the magnesium-aluminum-carbon bricks can be turned into the particle size required for production. However, the crushing is often carried out directly by a crusher. Due to the large difference between the brick body and the required particle size, the crushing efficiency cannot be effectively improved. At the same time, the difference between the brick body size and the crushed size adjusted by the crusher is too large, resulting in the problem that the crushing process affects the life of the crusher. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art.

[0054] A crushing mechanism 2, which is disposed on the frame 100 and is used to crush brick fragments of different sizes into uniform particle sizes in multiple times;

[0055] A dust removal mechanism 3, which is arranged on one side of the crushing mechanism 2 and is used to collect dust generated during the crushing process;

[0056] The crushing mechanism 2 includes a crushing assembly 21 arranged on the frame 100 and used for crushing the broken pieces, a particle size adjustment assembly 22 arranged on the crushing assembly 21 and used for controlling the size of the particles after crushing, a protective assembly 23 arranged on the crushing assembly 21 and used for preventing dust from accumulating at the position of the particle size adjustment assembly 22, a driving assembly 24 arranged on the frame 100 and used for driving the crushing assembly 21 to work, a material dropping adjustment assembly 25 arranged on the crushing assembly 21 and used for controlling the material dropping speed, and a fixing assembly 26 arranged on the crushing assembly 21 and used for improving the stability of the crushing assembly 21 during operation.

[0057] In this embodiment, by setting up a pre-processing mechanism 1, the initially crushed bricks are divided into three categories of large, medium and small and input into the crushing mechanism 2 in batches, and the crushing mechanism 2 is adjusted accordingly according to the size of the input brick fragments, so that during the crushing process, the size of the brick fragments is close to the size after crushing adjusted by the crusher, thereby improving the crushing efficiency and extending the service life of the crushing mechanism 2.

[0058] In detail, the recovered intact bricks are firstly crushed by hammering and transported to the pre-treatment mechanism 1 for screening, and the classified and stored brick fragments are input into the crushing mechanism 2 in batches for further crushing. During the process, the dust removal mechanism 3 guides and collects the dust generated by the crushing in time. After several cycles, the final state of the fragments changes from large to medium, medium to small, and small to powder, and then they are collected.

[0059] Further, if Figure 1-2 As shown, the pre-processing mechanism 1 includes a screening component 11 arranged on a frame 100 and used to classify the collected brick fragments, a pushing component 12 arranged on the screening component 11 and used to output the fragments of different particle sizes in batches, and a transmission component 13 designed on the frame 100 and used to transport and recover the fragments.

[0060] In this embodiment, a pre-processing mechanism 1 is provided, and the pre-processing mechanism 1 includes a screening component 11, a pushing component 12 and a transmission component 13. Under the action of the screening component 11, the initially crushed brick fragments are vibrated and screened, so that the fragments that need to be further crushed can be divided into three categories: large, medium and small, and processed in turn, so as to carry out the crushing work in a targeted manner and improve the work efficiency.

[0061] In detail, the recovered complete bricks are firstly crushed by hammering and transported to the screening component 11. Under the action of the screening component 11, the broken pieces are divided into three categories of large, medium and small for storage. Then, under the action of the pushing component 12, the broken pieces are output in batches. As the transmission component 13 enters the crushing mechanism 2, the crushed pieces are received by the transmission component 13 and recycled into the screening component 11 for further screening.

[0062] Further, if Figure 1-2 As shown, the screening assembly 11 includes a storage box 111 arranged on the frame 100, a screening box 113 connected to the storage box 111 through a first telescopic member 112, a first screening part 114, a second screening part 115 and a third screening part 116 arranged on the screening box 113 from top to bottom, a first motor 118 connected to the storage box 111 and having a driving wheel 117 connected to the output end, and a receiving seat 119 connected to the screening box 113 and cooperating with the driving wheel 117 to drive the screening box 113 to move.

[0063] In this embodiment, by providing a first screening section 114, a second screening section 115, a third screening section 116 and a storage box 111 located at the bottom of the screening box 113, brick fragments can be automatically classified under vibration, and the recovered fragments continue to be screened in the screening box 113, while the powdery fragments that meet the composite requirements are screened from the bottom of the screening box 113 and enter the storage box 111.

[0064] In detail, after the brick fragments enter the first screening part 114 at the top of the screening box 113, the first motor 118 starts to work and drives the driving wheel 117 to rotate through the output end, and the driving wheel 117 drives the receiving seat 119 to move upward. Then, when the driving wheel 117 cancels the support for the receiving seat 119, under the action of the self-gravity of the screening box 113 and the first telescopic member 112, the screening box 113 drives the brick fragments to vibrate, and the fragments are automatically screened and stored in the first screening part 114, the second screening part 115 and the third screening part 116 in the order of large, medium and small.

[0065] It should be noted that the aperture at the bottom of the screening box 113 is the smallest. Materials that meet the production requirements are screened through the bottom of the screening box 113 and then collected in the storage box 111. A baffle 328 that can be automatically adjusted up and down is provided on one side of the storage box 111 to cooperate with the vibration of the screening box 113 to assist in sealing.

[0066] Further, if Figure 1-2 As shown, the pushing assembly 12 includes a double-layer push plate 121 connected to the first screening part 114, the second screening part 115 and the third screening part 116 respectively, a second telescopic member 122 connected to the double-layer push plate 121 and connected to the screening box 113, a reciprocating screw rod 124 connected to the output end of the first motor 118 and connected to the bearing plate 123, and a driving cylinder 125 connected to the bearing plate 123 and used to push the double-layer push plate 121 to work;

[0067] The transmission component 13 includes a first conveyor belt 131 arranged on the frame 100 and with one end located at the blanking end of the screening box 113, a turnover box 132 connected to the frame 100 and with the inlet and outlet respectively connected to the first conveyor belt 131 and the top of the rolling component 21, and a second conveyor belt 133 arranged on the frame 100 and with its two ends respectively located below the rolling component 21 and at the top of the screening box 113.

[0068] In this embodiment, by setting the pushing assembly 12 that cooperates with the screening assembly 11, the pushing assembly 12 automatically completes the position adjustment during the screening process, and then completes the output of three groups of fragments in sequence, making the production work coordinated and unified, which is conducive to improving work efficiency.

[0069] In detail, while the first motor 118 drives the vibration screening work, the first motor 118 drives the reciprocating screw 124 to rotate, and the reciprocating screw 124 drives the carrying plate 123 to move, and then drives the driving cylinder 125 on the carrying plate 123 to move. After the first screening, the driving cylinder 125 is aligned with the first screening part 114, and the double-layer push plate 121 is pushed by the output end to transfer the broken pieces in the first screening part 114 to the first conveyor belt 131, and enter the crushing mechanism 2 through the turnover box 132. The crushed broken pieces are received by the second conveyor belt 133 and transferred to the top of the screening box 113, and vibrated and screened for the second time by the screening assembly 11. During the process, the driving cylinder 125 moves and aligns with the second screening part 115, and the cycle is repeated until the process of large-scale medium-scale, medium-scale small-scale, and small-scale powder is completed.

[0070] It should be noted that the double-layer push plate 121 completes the automatic reset work under the action of the second telescopic member 122; the first conveyor belt 131 and the second conveyor belt 133 are both provided with a cover body and a protrusion for auxiliary transmission, which is not shown in the figure.

[0071] Further, if Figure 3-5 As shown, the rolling assembly 21 includes a crushing box 211 connected to the frame 100, a feed hopper 212 connected to the top of the crushing box 211, two groups of adjustment holes 213 opened on the crushing box 211, a first rotating rod 215 and a second rotating rod 216 connected to the adjustment holes 213 through sealing plates 214, respectively, crushing rollers 217 connected to the first rotating rod 215 and the second rotating rod 216, respectively, two groups of guide plates 218 arranged on the crushing box 211 and a second motor 219 connected to the first rotating rod 215;

[0072] The particle size adjustment assembly 22 includes a mounting rod 221 respectively connected to the first rotating rod 215 and the second rotating rod 216 and located on the frame 100, a first adjustment rack 222 connected to the mounting rod 221, a third motor 223 connected to the frame 100, and a first adjustment gear 224 connected to the output end of the third motor 223 and meshing with the first adjustment rack 222.

[0073] In this embodiment, by setting the rolling component 21 and the particle size adjustment component 22 in the crushing mechanism 2, the crushing work can be adjusted accordingly according to the size of the input batch of brick fragments, so as to achieve the sequential crushing results of the brick fragments, that is, the process of large to medium, medium to small, and small to powder, thereby improving production efficiency and increasing the service life of the equipment.

[0074] In detail, the brick fragments enter the feed hopper 212 at the top of the crushing box 211 from the turnover box 132, and then fall down and are crushed by the crushing rollers 217 on the first rotating rod 215 and the second rotating rod 216. When the input particle size becomes smaller, the particle size adjustment component 22 drives the first adjusting gear 224 to rotate through the third motor 223, and then drives the mounting rods 221 on both sides and the first rotating rod 215 and the second rotating rod 216 to move closer to each other by a certain distance through the first adjusting rack 222, thereby changing the size of the crushed fragments.

[0075] It should be noted that the second motor 219 drives the first rotating rod 215 to rotate, and cooperates with the driving assembly 24 to drive the second rotating rod 216 to rotate; a dust curtain is provided below the crushing box 211 and in cooperation with the second conveyor belt 133 to prevent dust from overflowing without affecting the output of broken pieces.

[0076] Further, if Figure 6-9 As shown, the protection component 23 includes an air chamber 231 opened on both sides of the adjustment hole 213 and connected to both ends of the sealing plate 214, an exhaust passage 232 opened on both sides of the adjustment hole 213 and connected to the air chamber 231, and an intake passage 233 opened on the air chamber 231 and connected to the outside;

[0077] The driving assembly 24 includes a sleeve rod 241 connected to the second rotating rod 216, a first gear 242, a second gear 243 and a third gear 244 respectively connected to the first rotating rod 215 and the sleeve rod 241 and corresponding to each other, an auxiliary frame 245 connected to the frame 100 and connected to one end of the sleeve rod 241, a fourth motor 246 connected to the frame 100, and a screw rod 247 connected to the output end of the fourth motor 246 and used to drive the auxiliary frame 245 to move.

[0078] In this embodiment, by setting the protective component 23 in the crushing mechanism 2, the power during the change of the particle size adjustment component 22 is used to drive air to be introduced into the device from the outside, and the air is guided to be sprayed at the sliding seal between the particle size adjustment component 22 and the crushing box 211 to blow away the dust accumulated there and diffuse it to the surroundings, thereby ultimately ensuring the cleanliness of the sliding seal and effectively preventing the long-term accumulation of dust and the technical problem of continuous infiltration of dust into the sliding seal causing obstruction of operation.

[0079] In detail, when the first rotating rod 215 and the second rotating rod 216 change, the sealing plate 214 is driven to move horizontally in the adjustment hole 213, thereby preventing the leakage of dust. At the same time, the movement of the air chambers 231 at both ends of the sealing plate 214 will drive the outside air to enter the air chamber 231 on one side from the air inlet channel 233 under the action of negative pressure, and the air is ejected from the exhaust channel 232 by squeezing the air in the air chamber 231 on the other side to disperse the dust at the sliding sealing position between the sealing plate 214 and the adjustment hole 213; when the second motor 219 drives the first rotating rod 215 to rotate, the second motor 219 is connected to the first rotating rod 215 respectively. The first gear 242 meshing with the sleeve rod 241 is transmitted, and then the second rotating rod 216 is driven to rotate. At this time, the size after crushing is adjusted to the maximum. When adjustment is needed, first the fourth motor 246 drives the screw rod 247 to rotate, and the screw rod 247 drives the auxiliary frame 245 to move to one side. At this time, the two groups of first gears 242 are misaligned, and the two groups of second gears 243 are aligned but not meshed. Then, during the adjustment process of the particle size adjustment component 22, the first rotating rod 215 and the second rotating rod 216 are driven to approach each other, so that the two groups of second gears 243 are meshed. At this point, the adjustment is completed. If it needs to be adjusted again, just follow the above process.

[0080] It should be noted that when the sealing plate 214 moves to one side, the scraping effect between the sealing plate 214 and the adjustment hole 213 causes dust to accumulate at the connection position. At this time, air flow is ejected from the accumulated side to disperse it; one-way valves are provided in both the exhaust channel 232 and the intake channel 233.

[0081] Further, if Figure 10-15 As shown, the blanking adjustment assembly 25 includes two first rotating shafts 252 respectively connected to the mounting rod 221 and respectively connected to the first rotating rod 215 and the second rotating rod 216 through a first belt transmission member 251, a rotating plate 253 connected to the first rotating shaft 252, a protrusion 255 connected to the rotating plate 253 through a first spring 254, and two groups of lip plates 257 connected to the feed hopper 212 through a torsion spring member 256;

[0082] The fixing assembly 26 includes a fixing frame 261 connected to the frame 100, a U-shaped frame 262 connected to the fixing frame 261, a plurality of fixing grooves 263 provided on the fixing frame 261, a driving block 265 connected to the fixing groove 263 via a second spring 264, a fixing block 267 connected to the fixing groove 263 and connected to the driving block 265 via a third spring 266, two groups of second adjusting racks 269 connected to the U-shaped frame 262 and connected to an extrusion plate 268, a transmission rod 2611 connected to the U-shaped frame 262 and connected to an output end of the fourth motor 246 via a second belt transmission member 2610, a second adjusting gear 2612 connected to the transmission rod 2611 and meshing with the second adjusting rack 269, and a locking groove 260 provided on the mounting rod 221.

[0083] In this embodiment, a material dropping adjustment component 25 is provided to cooperate with the rolling component 21. After the particle size adjustment component 22 changes, the rotation speed of the rolling component 21 also changes accordingly, thereby crushing fragments of different sizes. At this time, due to the change in the rotation speed of the rolling component 21, the fragment input speed of the material dropping adjustment component 25 also changes accordingly, thereby achieving a state in which large fragments rotate slowly, feed slowly, and have a strong crushing force, and small fragments rotate quickly, feed quickly, and have a high crushing efficiency, thereby effectively extending the service life of the rolling component 21.

[0084] In detail, the first rotating rod 215 and the second rotating rod 216 drive the first rotating shaft 252 and the rotating plate 253 to rotate through the first belt transmission member 251, and the rotating plate 253 drives the protrusion 255 to squeeze the lip plate 257 to rotate and open. At this time, the broken pieces fall down. When the lip plate 257 rotates to a certain angle, it stops rotating. Due to the squeezing, the protrusion 255 drives the first spring 254 to shrink and pass over the lip plate 257, and the lip plate 257 is reset under the action of the torsion spring member 256; before the particle size adjustment component 22 needs to be changed, the driving component 24 first changes the corresponding positions of the first gear 242, the second gear 243 and the third gear 244 on the sleeve rod 241 through the fourth motor 246, and at the same time, the fourth motor 246 drives the transmission rod 2611 to rotate through the second belt transmission member 2610, and the transmission rod 2611 drives the second gears on both sides through the second adjustment gear 2612 The adjusting rack 269 moves, and the second adjusting rack 269 drives the squeezing plate 268 to move away from the driving block 265 on one side and squeeze the next driving block 265. At this time, the driving block 265 that has been squeezed out moves the corresponding fixing block 267 out of the locking groove 260 on the mounting rod 221 under the action of the corresponding second spring 264 and the third spring 266, and the adjacent driving block 265 is squeezed. Since the adjacent fixing block 267 is blocked by the mounting rod 221 and cannot move, the second spring 264 and the third spring 266 shrink at the same time. After the particle size adjustment component 22 drives the mounting rod 221 to move, the locking groove 260 on the mounting rod 221 is aligned with the fixing block 267. At this time, the third spring 266 stretches to drive the fixing block 267 to be stuck in the locking groove 260, and the fixing work of the mounting rod 221 is completed again to ensure stability during the crushing process.

[0085] It should be noted that, in the resetting process of the crushing mechanism 2, the driving assembly 24 first drives the sleeve rod 241 to move backward, causing the third gear 244 to be misplaced, and at this time, the extrusion plate 268 is synchronously driven to move and separate from all the driving blocks 265, canceling the fixation of the mounting rod 221, and then the particle size adjustment assembly 22 drives the mounting rod 221 to reset to the initial position, and the driving assembly 24 drives the sleeve rod 241 to move forward and return to the initial position. At this time, the two first gears 242 just complete the meshing work, and the extrusion plate 268 moves accordingly to drive the corresponding fixing block 267 to fix the position of the mounting rod 221, thereby completing the resetting work.

[0086] Further, if Figure 1 and Fig.16 As shown, the dust removal mechanism 3 includes a drainage component 31 arranged on one side of the rolling component 21 and used to drive the airflow, an opening and closing component 32 arranged on the drainage component 31 and used to control the direction of the airflow, and a cleaning component 33 arranged on the drainage component 31 and used to clean dust.

[0087] It is worth mentioning here that by setting up a dust removal mechanism 3, the dust removal mechanism 3 includes a drainage component 31, an opening and closing component 32 and a cleaning component 33. During the crushing process, the dust floating inside the crushing box 211 is timely guided and collected, and the cleaning component 33 and the opening and closing component 32 work alternately and uninterruptedly, thereby ensuring the continuity of dust control and avoiding the technical problem of dust clogging the filter 314 and affecting the dust diversion effect.

[0088] In detail, first, the drainage component 31 drives the dust to move by guiding the direction of the airflow, and then the opening and closing component 32 changes the path of the airflow and dust, and the cleaning component 33 quickly completes the dust cleaning work in the path where the flow is stopped.

[0089] Further, if Figure 16-17 As shown, the drainage assembly 31 includes a drainage pipe 311 connected to one side of the crushing box 211, a first circulation portion 312 and a second circulation portion 313 arranged in the drainage pipe 311, a filter screen 314 respectively arranged on the first circulation portion 312 and the second circulation portion 313, and a drainage fan blade 316 connected to the frame 100 through a second rotating shaft 315 and located at the outlet of the drainage pipe 311;

[0090] The opening and closing assembly 32 includes a rectangular frame 321 connected to the frame 100, a half gear 323 connected to the frame 100 through a third rotating shaft 322, two sets of follower racks 324 connected to the rectangular frame 321 and meshing with the half gear 323 for transmission, a fifth motor 326 connected to the frame 100 and respectively connected to the second rotating shaft 315 and the third rotating shaft 322 through a sprocket chain transmission member 325, a baffle 328 connected to the first circulation part 312 and the second circulation part 313 through a fourth rotating shaft 327, a flip gear 329 connected to the fourth rotating shaft 327, and a flip rack 3210 connected to the rectangular frame 321 and meshing with the corresponding flip gear 329 for transmission.

[0091] In this embodiment, by providing the first circulation portion 312 and the second circulation portion 313 in the guide tube 311, and then cooperating with the opening and closing component 32, alternating circulation of airflow is achieved, so that when cleaning is needed, uninterrupted collection of dust in the crushing box 211 can be achieved, ensuring that dust will not be scattered during the crushing process.

[0092] In detail, first, the fifth motor 326 drives the second rotating shaft 315 to rotate through the sprocket chain transmission member 325, and the second rotating shaft 315 drives the guide fan blade 316 to rotate, thereby driving the airflow and dust in the crushing box 211 to enter the guide pipe 311, and at the same time, the sprocket chain transmission member 325 drives the third rotating shaft 322 to rotate, and the third rotating shaft 322 drives the half gear 323 to rotate, and the half gear 323 then drives the rectangular frame 321 to reciprocate horizontally through two follower racks 324 staggered up and down. During the process, the rectangular frame 321 drives the flip racks 3210 staggered on both sides to move, and the flip rack 3210 drives the flip gear 329 to rotate 90°. During the reciprocating process, the fourth rotating shaft 327 and the baffle 328 realize the alternating opening and closing of the first circulation part 312 and the second circulation part 313.

[0093] Embodiment 2

[0094] like Figure 16-19 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0095] Further, if Figure 16-19 As shown, the cleaning assembly 33 includes an avoidance groove 331 respectively opened on the first circulation part 312 and the second circulation part 313, a water box 332 connected to the avoidance groove 331, a brush plate 334 connected to the water box 332 and connected to the cross bar 333, a trigger rod 335 connected to the avoidance groove 331 and extending into the water box 332, a triangular block 336 respectively connected to both ends of the cross bar 333 and cooperating with the trigger rod 335 to drive the brush plate 334 to move up and down, and a push rod 338 connected to the rectangular frame 321 and connected to the driving groove 337 on the water box 332.

[0096] It is worth mentioning that by setting the cleaning component 33, the dust collection work on the filter 314 is quickly completed when the corresponding channel is closed, so that the dust is no longer accumulated on the filter 314, ensuring the stable and continuous dust collection work.

[0097] In detail, when the rectangular frame 321 moves back and forth, if the first circulation portion 312 is closed, the rectangular frame 321 continues to drive the push rod 338 to move, and the push rod 338 simultaneously drives the water box 332 to move, until the water box 332 is about to reach the boundary of the first circulation portion 312, and the trigger rod 335 stops moving due to the friction between the triangular block 336 on one side of the cross bar 333. At this time, due to the influence of the obstruction force, the push rod 338 moves to the end in the driving groove 337, and then the force directly applied by the push rod 338 on the water box 332 causes the triangular block 336 to move. 6 moves upward under the pressure of the trigger rod 335, and the water box 332 also moves to the boundary of the first circulation part 312. When the triangular block 336 moves, it drives the cross bar 333 and the brush plate 334 to move upward, so that the brush part of the brush plate 334 contacts the filter 314. Then, during the resetting process, the brush plate 334 continuously sweeps the dust on the filter 314 and collects it in the clean water in the water box 332. In the final stage of resetting, the trigger rod 335 squeezes the triangular block 336 on the other side of the cross bar 333, so that the push rod 338 is reset, and finally drives the brush plate 334 to reset.

[0098] It should be noted that there is a certain friction between the push rod 338 and the driving groove 337, and there is a certain friction between the horizontal plate and the inner wall of the water box 332, so the brush plate 334 will not fall automatically when sweeping away dust.

[0099] Working process:

[0100] First, the recovered complete bricks are initially knocked and crushed and transported to the screening component 11. Under the action of the screening component 11, the broken pieces are divided into three categories of large, medium and small for storage. Then, under the action of the pushing component 12, the broken pieces are output in batches. As the transmission component 13 enters the crushing mechanism 2, the broken pieces are received by the transmission component 13 and recycled to the screening component 11 for further screening. During the crushing process, the brick pieces enter the feed hopper 212 at the top of the crushing box 211 from the turnover box 132, and then the rolling component 21 and the driving component 24 cooperate to crush them. When the rolling component 21 works, it drives the falling material adjustment component 25 to work and control the falling material speed. When the size of the input broken pieces changes, the driving component 24 first changes the first gear on the sleeve rod 241 through the fourth motor 246. 242, the corresponding positions of the second gear 243 and the third gear 244, and the fixing effect of the fixing component 26 on the mounting rod 221 is cancelled at the same time, and then the particle size adjustment component 22 completes the adjustment of the spacing, and the fixing component 26 automatically fixes the mounting rod 221 after the particle size adjustment component 22 completes the adjustment of the spacing, and the protective component 23 disperses the dust at the sliding sealing position of the sealing plate 214 and the adjustment hole 213, and the dust generated in the crushing process is driven to move by guiding the airflow direction through the drainage component 31, and then the path of the airflow and dust is changed under the action of the opening and closing component 32, and the cleaning component 33 quickly completes the dust cleaning work in the path where the circulation is stopped, and finally the brick fragments complete the process of large-medium, medium-small, and small-powder and are collected in the storage box 111.
