Technical Field

[0001] This invention belongs to the field of waste treatment technology, specifically a device for the efficient separation and resource recovery of lightweight debris from construction waste. Background Technology

[0007] The moving mechanism includes a moving plate, the bottom end of which is hinged to a crossbar via a hinge rod. A fixed plate is fixedly connected to the outer wall of the crushing box, and a fixed block is fixedly connected to the outer wall of the crushing box. A motor is fixedly connected to the inner wall of the fixed block, and a cam is fixedly connected to the output shaft of the motor.

[0008] Preferably, the screen is elastically connected to the inner wall of the crushing box by a return spring, and the fixed plate and the moving plate are elastically connected by a connecting spring.

[0009] Preferably, the movable plate is slidably connected to the outer wall of the crushing box, the two ends of the hinge rod are respectively hinged to the crossbar and the outer wall of the movable plate, and the crossbar is slidably connected to the inner wall of the crushing box.

[0010] Preferably, the crossbar is fixedly connected to the outer wall of the screen, the screen is slidably connected to the inner wall of the crushing box, and the cam is in contact with the outer wall of the moving plate.

[0011] Preferably, the two ends of the connecting spring are fixedly connected to the outer walls of the fixed plate and the moving plate, respectively; one end of the reset spring is fixedly connected to the outer wall of the screen; and the other end of the reset spring is fixedly connected to the inner wall of the crushing box.

[0012] Preferably, the feeding mechanism includes a synchronous wheel A, the outer wall of the synchronous wheel A is connected to a synchronous wheel B via a synchronous belt drive, the inner wall of the fixed block is elastically connected to a rotating rod via a spiral spring, the outer wall of the rotating rod is fixedly connected to a material cylinder, and both the rotating rod and the outer wall of the synchronous wheel B are fixedly connected to half gears.

[0013] Preferably, the synchronous wheel A is fixedly connected to the outer wall of the cam, the synchronous wheel B is fixedly connected to the inner wall of the fixed block, one end of the spiral spring is fixedly connected to the outer wall of the rotating rod, the other end of the spiral spring is fixedly connected to the inner wall of the fixed block, the rotating rod is rotatably connected to the fixed block and the inner wall of the feed inlet, and the material cylinder is rotatably connected to the inner wall of the feed inlet.

[0014] Preferably, the screening mechanism includes a connecting block, the inner wall of the connecting block is elastically connected to a partition plate by a telescopic spring, the outer wall of the partition plate contacts a screen plate, and the inner wall of the connecting block is elastically connected to a stop block by a compression spring.

[0015] Preferably, the connecting block is fixedly connected to the conveying pipe on the outer wall of the air separator, one end of the telescopic spring is fixedly connected to the outer wall of the partition, the other end of the telescopic spring is fixedly connected to the inner wall of the connecting block, the partition is slidably connected to the inner wall of the connecting block, and the partition is in contact with the screen plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention, through the combination of a movable plate and a cam, allows the cam to move eccentrically after the motor starts. The cam then drives the movable plate to move vertically back and forth under the action of the connecting spring, causing the hinge rod to flip and the crossbar to move horizontally. This allows the crossbar to drive the screen to move horizontally back and forth continuously. When the crushed waste falls onto the screen, the movement of the screen can improve the screening efficiency and avoid the problem of waste accumulating and clogging on the screen or being unable to feed due to the screen not being able to move.

[0019] This invention, through the cooperation of structures such as half gears and material cylinders, allows the half gears to rotate via synchronous wheels A and B during the rotation of the cam. Each rotation of the cam can drive the material cylinder to rotate half a rotation and automatically reset, thus emptying the waste in the trough into the crushing box. The intermittent feeding can avoid the problem of waste accumulating on the crushing roller due to excessive feeding speed, which would cause the crushing roller to be overloaded and malfunction.

[0020] This invention, through the combination of partitions and blocks, allows for the direct insertion and pressing down of another set of screens when replacing a screen plate. The partition below the screens pushes the block to move, releasing the old screen plate from its restriction on the lower partition. The telescopic spring then moves the old screen plate and the partition upwards synchronously, allowing it to be removed. This quick screen plate replacement can be completed without stopping the conveyor, resulting in high efficiency. Attached Figure Description

[0034] 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.

[0035] like Figures 1 to 7 As shown, the present invention provides an efficient separation and resource utilization device for lightweight debris in construction waste, including a crushing box 100 and a conveyor 600. A feed inlet 500 is fixedly connected to the top outer wall of the crushing box 100, and an air separator 700 is fixedly connected to the top outer wall of the conveyor 600. A collection box 900 is provided on the inner wall of the crushing box 100. The device also includes: a screen 800, which is disposed in the inner wall of the crushing box 100 via a moving mechanism 200; a feeding mechanism 300, which is installed on the outer wall of the crushing box 100; and a screening mechanism 400, which is disposed on the conveying pipe on the outer wall of the air separator 700.

[0036] The moving mechanism 200 includes a moving plate 201, the bottom end of which is hinged to a crossbar 203 via a hinge rod 202. A fixing plate 205 is fixedly connected to the outer wall of the crushing box 100. A fixing block 209 is fixedly connected to the outer wall of the crushing box 100. A motor 206 is fixedly connected to the inner wall of the fixing block 209. A cam 207 is fixedly connected to the output shaft of the motor 206.

[0037] like Figures 2 to 4 As shown, the screen 800 is elastically connected to the inner wall of the crushing box 100 by a return spring 208, and the fixed plate 205 and the moving plate 201 are elastically connected by a connecting spring 204.

[0038] Using the above scheme: Demolition waste from buildings, bridges, and railways typically includes aggregates such as concrete, bricks, tiles, and stone, as well as some lightweight plastic waste. Both aggregates and plastic waste can be fed into the crushing box 100 through the inlet 500. They are first initially crushed to a suitable size by crushing rollers. Larger particles pass through the screen 800 and are conveyed into the conveyor 600, while extremely small particles fall into the collection box 900 for further processing. Fine aggregates can be directly used as core fine aggregates for mortar, and modified plastic powder can be used as a modifier for mortar or lightweight concrete. While the conveyor 600 transports larger aggregates and plastic waste, a negative pressure air classifier 700 can suck the lightweight plastic waste into the conveying pipe and transport it to another location. The waste is conveyed on conveyor 600. Heavier aggregates cannot be sucked in by air classifier 700, but are still conveyed by conveyor 600 and sent to the pre-treatment equipment for concrete preparation for processing, thus completing the separation of light and heavy waste. When lightweight plastic waste is conveyed through the conveyor pipe, it can be further screened by screening mechanism 400. Small plastic particles can be conveyed to plastic hot melt machine on another conveyor 600 through screen 800 for processing, while larger plastic particles cannot pass through screen 800 and fall into another set of collection boxes 900 from the opening under the connecting block 401. They can then be sent to granulator for processing, thus recycling both aggregates and plastics in the construction waste.

[0039] like Figures 2 to 4 As shown, the movable plate 201 is slidably connected to the outer wall of the crushing box 100. The two ends of the hinge rod 202 are respectively hinged to the crossbar 203 and the outer wall of the movable plate 201. The crossbar 203 is slidably connected to the inner wall of the crushing box 100. The crossbar 203 is fixedly connected to the outer wall of the screen 800. The screen 800 is slidably connected to the inner wall of the crushing box 100. The cam 207 is in contact with the outer wall of the movable plate 201. The two ends of the connecting spring 204 are respectively fixedly connected to the outer wall of the fixed plate 205 and the movable plate 201. One end of the return spring 208 is fixedly connected to the outer wall of the screen 800. The other end of the return spring 208 is fixedly connected to the inner wall of the crushing box 100.

[0040] The above solution is adopted: By setting the moving mechanism 200, the screen 800 can be continuously swayed left and right during the screening process to prevent the pre-crushed waste from remaining on the screen 800 and causing blockage or failure to discharge downwards. After the motor 206 is started by the control system, its output shaft can drive the cam 207 to rotate. The cam 207 makes an eccentric motion. Under normal conditions, its larger end is in contact with the moving plate 201. The moving plate 201 is in a certain position under the influence of the fixed plate 205 and the connecting spring 204. When the smaller end of the cam 207 rotates to contact the moving plate 201, it will squeeze the moving plate 201 downwards and compress the connecting spring 204. At this time, the moving plate 201 will drive one end of the hinge rod 202 to move downwards synchronously. The hinge rod 202 drives the crossbar 20 3. Movement: Since the crossbar 203 passes through one side of the outer wall of the crushing box 100, it can only move laterally, thus driving the screen 800 to move laterally synchronously. The screen 800 will compress the return spring 208. Then, after the cam 207 rotates one revolution, it returns to the state where the larger end is in contact with the moving plate 201. At this time, the connecting spring 204 resets the moving plate 201 due to its elasticity. The hinge rod 202 and the crossbar 203 move in opposite directions synchronously to reset. The return spring 208 pushes the screen 800 to move horizontally to reset due to its elasticity. Thus, during the operation of the motor 206, the continuous rotation of the cam 207 can drive the screen 800 to move back and forth laterally continuously, so that the garbage on its surface moves continuously, avoiding the problem of blockage or affecting the discharge of the screen 800.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, the feeding mechanism 300 includes a synchronous pulley A301. The outer wall of the synchronous pulley A301 is connected to a synchronous pulley B303 via a synchronous belt 302. The inner wall of the fixed block 209 is elastically connected to a rotating rod 307 via a spiral spring 306. The outer wall of the rotating rod 307 is fixedly connected to a material cylinder 305. The outer walls of both the rotating rod 307 and the synchronous pulley B303 are fixedly connected to half gears 304.

[0042] The above solution is adopted: the feeding mechanism 300 can be linked with the motor 206 in the moving mechanism 200. During the start-up process of the motor 206, the material cylinder 305 is driven to rotate intermittently. The material cylinder 305 is provided with a material trough, and the garbage can fall into the material trough. When the material cylinder 305 rotates to the point where the material trough faces downward, the garbage can fall into the crushing box 100 for crushing. When the material cylinder 305 rotates in the opposite direction to reset, the material trough faces upward, and the feeding of garbage can be stopped. This achieves the effect of intermittent feeding, avoiding the problem of garbage accumulating on the crushing roller due to the excessive feeding speed and the slow crushing speed of the crushing roller.

[0043] like Figure 2 , Figure 3 and Figure 5As shown, synchronous pulley A301 is fixedly connected to the outer wall of cam 207, synchronous pulley B303 is fixedly connected to the inner wall of fixed block 209, one end of spiral spring 306 is fixedly connected to the outer wall of rotating rod 307, the other end of spiral spring 306 is fixedly connected to the inner wall of fixed block 209, rotating rod 307 is rotatably connected to fixed block 209 and inner wall of feed inlet 500, and material cylinder 305 is rotatably connected to inner wall of feed inlet 500.

[0044] Using the above scheme: After the motor 206 starts, it can drive the synchronous pulley A301 to rotate synchronously through the cam 207, and drive the synchronous pulley B303 of the same diameter to rotate through the synchronous belt 302, which in turn drives the half gear 304 on its outer wall to rotate synchronously; the two sets of half gears 304 can mesh under certain conditions, but under normal conditions the two gears do not contact each other. The spiral spring 306 drives the rotating rod 307 and its outer wall half gear 304 to be stationary, and the feed chute of the material cylinder 305 faces upward; when the motor 206 drives the cam 207 and the synchronous pulley A301 to rotate half a turn, the half gear 304 on the outer wall of the synchronous pulley B303 can rotate to the state where it just contacts the gear on the outer wall half gear 304 of the rotating rod 307. After the cam 207 and the synchronous pulley A301 continue to rotate, since the two sets of half gears 304 have already meshed, one set of half gears... Half gear 304 drives another set of half gears 304 to rotate half a turn, which in turn drives the rotating rod 307 and the material cylinder 305 to rotate half a turn. The spiral spring 306 is compressed under force, and the material trough faces downward, allowing the internal waste to be poured into the crushing box 100 to complete one feeding cycle. At this time, the waste stays on the other side of the material cylinder 305 and will not enter the crushing box 100. After the cam 207 and the synchronous wheel A301 rotate one turn, the two sets of half gears 304 separate again. The elastic force of the spiral spring 306 drives the rotating rod 307 and the material cylinder 305 to rotate in the opposite direction to reset. The waste re-enters the material trough to wait for the next feeding cycle. Thus, when the cam 207 rotates one turn and the screen 800 moves back and forth once, the material cylinder 305 rotates half a turn to automatically feed once, avoiding the problem of excessive feeding at one time and accumulation on the crushing roller, which would cause the crushing roller to overload and malfunction.

[0045] like Figure 6 and Figure 7 As shown, the screening mechanism 400 includes a connecting block 401. The inner wall of the connecting block 401 is elastically connected to a partition 404 via a telescopic spring 403. The outer wall of the partition 404 contacts a screen plate 402. The inner wall of the connecting block 401 is elastically connected to a stop block 406 via a compression spring 405.

[0046] The above scheme is adopted: the screen plate 402 in the screening mechanism 400 can be used to separate plastic waste of different sizes and send it to different equipment for resource recycling. The screen plate 402 can be replaced conveniently and quickly without stopping the machine, ensuring the continuity of the overall conveying process. There are two sets of telescopic springs 403 and partitions 404. The screen plate 402 can be placed on the partition 404 for fixation. A cover plate is hinged above the connecting block 401. The cover plate can be magnetically fixed above the connecting block 401 to fix the screen plate 402.

[0047] like Figure 6 and Figure 7 As shown, the connecting block 401 is fixedly connected to the conveying pipe on the outer wall of the air separator 700. One end of the telescopic spring 403 is fixedly connected to the outer wall of the partition plate 404, and the other end of the telescopic spring 403 is fixedly connected to the inner wall of the connecting block 401. The partition plate 404 is slidably connected to the inner wall of the connecting block 401, and the partition plate 404 is in contact with the screen plate 402. One end of the compression spring 405 is fixedly connected to the outer wall of the stop block 406, and the other end of the compression spring 405 is fixedly connected to the inner wall of the connecting block 401. The stop block 406 is slidably connected to the inner wall of the connecting block 401, and the stop block 406 is in contact with the outer wall of the partition plate 404.

[0048] Using the above solution: Under normal use, a set of sieve plates 402 can be placed inside the connecting block 401, and placed on a set of partitions 404. This set of partitions 404 is lower than another set of partitions 404, located below the stop block 406, and the telescopic spring 403 below this set of partitions 404 is in the retracted state. The other set of partitions 404 is above the stop block 406, and the stop block 406 can limit the lower partition 404. When residual fabric or dust impurities in the plastic waste cause the mesh of the sieve plate 402 to be blocked, affecting the screening effect, and the sieve plate 402 needs to be replaced, the cover can be opened, the new sieve plate 402 can be inserted into the empty partition 404 and then pressed down. The partition 404 moves down and squeezes the arc surface of the stop block 406, causing it to move towards the connecting block. After the block 406 moves within the side wall of 401 and disengages from the lower partition 404, the telescopic spring 403, due to its elasticity, will cause the partition 404 and the old screen plate 402 above to move upwards simultaneously, allowing them to be removed. At the same time, after the new screen plate 402 is inserted, the partition 404 moves downwards to below the block 406, the telescopic spring 403 contracts under force, and the block 406 pops out under the elasticity of the compression spring 405, limiting the partition 404 and completing the installation of the new screen plate 402. After closing the cover, the switching operation of the old and new screen plates 402 is completed. The screen plates 402 can be replaced conveniently and quickly while ensuring that there is always a set of screen plates 402 in the connecting block 401, without affecting the normal conveying of the air separator 700, resulting in higher efficiency.

[0049] Working principle and usage process of this invention:

[0050] Construction waste containing concrete, bricks, stone aggregates, and lightweight plastics is fed into the feed inlet 500. The motor 206 is started, causing its output shaft to drive the cam 207 to rotate. The cam 207 drives the synchronous wheel B303 to rotate through the synchronous wheel A301 and the synchronous belt 302, which in turn drives the half gear 304 on the outer wall of the synchronous wheel B303 to rotate. After the cam 207 rotates half a turn, the two sets of half gears 304 mesh. When it continues to rotate, it can drive the rotating rod 307 and the material cylinder 305 to rotate half a turn. The material trough of the material cylinder 305 faces downward, and the waste it carries is put into the crushing box 100. After the cam 207 rotates one turn, the two sets of half gears 304 separate. The spring force of the spiral spring 306 drives the rotating rod 307 and the material cylinder 305 to return to their original positions. The material trough faces upward again to receive waste, completing one intermittent feeding cycle. This can avoid the problem of excessive accumulation of crushing rollers and excessive load caused by excessive feeding speed, and ensure the stable operation of subsequent crushing processes.

[0051] Waste falling from the feed cylinder 305 into the crushing box 100 undergoes initial crushing via the crushing rollers. During the crushing process, the motor 206 drives the cam 207 to rotate eccentrically. The smaller end of the cam 207 presses the moving plate 201 downward, compressing the connecting spring 204. The moving plate 201 pushes the crossbar 203 to move laterally via the hinge rod 202, thereby driving the screen 800 to move horizontally and compressing the reset spring 208. When the cam 207 rotates to the point where its larger end contacts the moving plate 201, the connecting spring 204 and the reset spring 208 are spring-forced to reset, driving the crossbar 203 and the screen 800 to move in the opposite direction, thus realizing the reciprocating lateral movement of the screen 800. In the crushed waste, larger particles fall through the screen 800 into the conveyor 600, while extremely small particles pass through the screen 800 and fall into the collection box 900. The aggregate is directly recycled as the core fine aggregate for mortar, and the plastic powder is modified and used as a modified filler for mortar or lightweight concrete, completing the primary screening and particle classification.

[0052] The conveyor 600 uniformly transports the larger particles after primary screening to below the air separator 700. The negative pressure suction generated by the air separator 700 sucks the lightweight plastic waste into the conveying pipe on its outer wall, while the heavier concrete, bricks, tiles, and stone aggregates cannot be sucked in due to gravity and continue to be transported with the conveyor 600 to the pre-treatment processing equipment at the front end of concrete preparation, completing the core separation operation of light and heavy waste.

[0053] Lightweight plastic waste from the air separator 700 conveyor pipe is transported to the connecting block 401 of the screening mechanism 400. It undergoes secondary screening via the screen plate 402 within the connecting block 401. Small plastic particles pass through the mesh of the screen plate 402 and fall into another conveyor 600 below, subsequently being transported to the plastic hot melt machine for processing. Larger plastic particles cannot pass through the screen plate 402 and fall into a dedicated collection box 900 through an opening below the connecting block 401, subsequently being transported to the granulator for processing. During the screening process, if the mesh of the screen plate 402 is damaged due to fabric... If dust or impurities cause blockage, open the cover plate above the connecting block 401, place the new screen plate 402 on the empty partition plate 404 and press it down. Press the stop block 406 to make it retract into the side wall of the connecting block 401. The old screen plate 402 moves upward with the original partition plate 404 under the action of the telescopic spring 403. After removing the old screen plate 402, the partition plate 404 corresponding to the new screen plate 402 moves down to below the stop block 406 and is limited. Then the cover plate can be closed to complete the replacement. The operation can be completed quickly without interrupting the conveying process, which is highly efficient.
