Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, specifically to a waste separation and recycling device for road base paving. Background Technology

[0002] Roadbed paving waste separation and recycling devices are used to separate roadbed paving waste by size or material. These devices come in various forms, with the drum screen being one type. The drum screen is arranged at an angle, higher at one end and lower at the other, relying on the rotation of the drum to move and screen the material. Most commonly available models are single-layer structures, but some also have axially segmented sections with screens of different aperture sizes, grading by particle size. Material is fed from the upper end and slides down the drum as it rotates. Particles matching the aperture size are screened layer by layer, while larger particles are discharged from the lower end. The structure is simple and inexpensive, making it widely used on construction sites for simple particle size screening of roadbed paving waste.

[0003] Existing rotary drum screens are generally single-layer structures or axially segmented with screens of different aperture sizes. Therefore, to screen particles of different aperture sizes layer by layer, multiple screens of different aperture sizes need to be connected axially, or multiple rotary drum screens of different aperture sizes need to be used. This results in a large footprint and space consumption. At the same time, if a single rotary drum screen of different aperture sizes is used, multiple feeding and separation processes are required, which is time-consuming, labor-intensive, reduces separation efficiency, and increases the workload of workers. Summary of the Invention

It solves the problems of existing drum screens, which are mostly single drum screens with different apertures or drum screens with different apertures arranged in axial segments. As a result, they occupy a large area and space. Furthermore, if a single drum screen with different apertures is used, it will cause multiple feedings, which is time-consuming and labor-intensive, reduces separation efficiency, and increases workload.

[0016] 1. This invention can separate waste materials of multiple aperture sizes at one time through a multi-layer separation mechanism.

[0028] The technical solutions in 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.

[0029] Please see the appendix Figure 1 - Appendix Figure 9This invention provides a road base paving waste separation and recycling device, including a placement frame 1. A multi-layer separation mechanism 2 is installed on the top of the placement frame 1. The placement frame 1 provides an installation position and a foundation for placing the multi-layer separation mechanism 2. A vibration mechanism 3 is installed in the middle of the placement frame 1, which generates vibration to prevent clogging of the holes in the multi-layer separation mechanism 2. A dust extraction mechanism 4 is installed outside the placement frame 1, which extracts the dust generated during waste separation by the multi-layer separation mechanism 2, thus preventing dust dispersion. A speed reducer 5 is fixedly connected to the outside of the placement frame 1. A motor 6 is installed inside the dust extraction mechanism 4, which reduces the speed of the motor 6. The motor 6 provides power. A transmission shaft 7 is fixedly connected to the output end of the motor 6, transmitting the rotational force of the motor 6's output end. The end of the transmission shaft 7 away from the motor 6 is fixedly connected to the input end of the speed reducer 5. A transmission rod 8 is rotatably connected to one side of the top of the placement frame 1. Multiple drive wheels 9 are fixedly connected to the outside of the device. The transmission rod 8 can transmit rotational force and can install the drive wheels 9. After the drive wheels 9 rotate, they can drive the multi-layer separation mechanism 2 to rotate. A belt is sleeved between the output end of the reducer 5 and one end of the transmission rod 8. Multiple auxiliary stabilizing wheels 10 are rotatably connected to the other side of the top of the placement frame 1. The auxiliary stabilizing wheels 10 can cooperate with the drive wheels 9 to maintain the stability of the multi-layer separation mechanism 2 when it rotates. Multiple mounting blocking wheels 11 are provided at one end of the top of the placement frame 1. The mounting blocking wheels 11 can abut against one end of the multi-layer separation mechanism 2, so that the multi-layer separation mechanism 2 is placed on the top of the placement frame 1 and prevented from falling off the placement frame 1. Two baffles 12 are fixedly connected to both sides of the top of the placement frame 1. The baffles 12 can prevent the waste material from falling out from the side when the multi-layer separation mechanism 2 is rolling. A funnel 13 is fixedly connected to the bottom of the top of the placement frame 1. The funnel 13 can guide the waste material to fall out. The bottom of the baffle 12 is fixedly connected to the top of the funnel 13.

[0030] The multi-layer separation mechanism 2 includes an outer filter cylinder 201, which performs the final stage of waste separation. The outer filter cylinder 201 is placed on top of the placement frame 1. Multiple ring rails 202 are fixedly connected to the outside of the outer filter cylinder 201. The ring rails 202 can drive the outer filter cylinder 201 to rotate when the power wheel 9 rotates. An outer retaining ring 203 is fixedly connected to one end of the outer filter cylinder 201, and an outer discharge ring 206 is fixedly connected to the other end of the outer filter cylinder 201. The outer discharge ring 206 can guide the larger waste material of the final stage to fall out. Multiple slots 204 are opened inside the outer retaining ring 203. Multiple outer ear clips 205 are fixedly connected to the inside of the outer filter cylinder 201. A middle filter cylinder 207 is provided, which can separate the second layer of waste. One end of the middle filter cylinder 207 is fixedly connected to a middle layer retaining ring 208, and the other end is fixedly connected to a middle layer discharge ring 213. The middle layer discharge ring 213 can guide larger waste materials to fall out during the second layer separation. The middle layer retaining ring 208 has multiple locking grooves 209 inside. One end of the middle filter cylinder 207 is fixedly connected to multiple locking plates 210. After the locking plates 210 are locked inside the locking grooves 204, they can form a relatively sealed ring between one end of the middle filter cylinder 207 and the outer filter cylinder 201, which can prevent waste materials from falling into the outer filter cylinder when they are put into the inner filter cylinder 214. Between the filter cartridge 201 and the middle filter cartridge 207, multiple middle support blocks 211 are fixedly connected to the outside of the middle filter cartridge 207. The middle support blocks 211 can engage with the inside of the outer layer catches 205, thereby allowing the middle filter cartridge 207 to be installed inside the outer filter cartridge 201. Multiple middle catches 212 are fixedly connected inside the middle filter cartridge 207. The catch plate 210 engages with the catch groove 204, and the middle support blocks 211 engage with the outer layer catches 205. An inner filter cartridge 214 is provided inside the middle filter cartridge 207. After the multi-layer separation mechanism 2 is placed on top of the placement frame 1, the ring rail 202 on the outer filter cartridge 201 can be placed on the power wheel 9 and the auxiliary stabilizing wheel 10. The end of cylinder 201 near the outer discharge ring 206 rests against the mounting blocking wheel 11. Since the placement frame 1 is positioned lower at the end of the outer discharge ring 206, a portion of the weight of the multi-layer separation mechanism 2 falls on the mounting blocking wheel 11. Therefore, the multi-layer separation mechanism 2 can be placed on top of the placement frame 1. After the motor 6 starts, it drives the transmission shaft 7 to rotate. The transmission shaft 7 drives the reducer 5 to rotate. The reducer 5 then transmits the power through a belt to drive the transmission rod 8 to rotate. The transmission rod 8 drives the power wheel 9 to rotate. The rotation of the power wheel 9 drives the ring rail 202 to rotate. The rotation of the ring rail 202 drives the outer filter cylinder 201 to rotate. The middle filter cylinder 207 is installed inside the outer filter cylinder 201.The inner filter cylinder 214 is installed inside the middle filter cylinder 207. Therefore, when the outer filter cylinder 201 rotates, it can drive the middle filter cylinder 207 and the inner filter cylinder 214 to rotate. At this time, the road base paving waste to be separated is put into the inner filter cylinder 214, and the inner filter cylinder 214 can perform the first separation. Smaller waste falls onto the middle filter cylinder 207, while larger waste is discharged through the inner discharge ring 217. The waste falling onto the middle filter cylinder 207 undergoes the second separation, while smaller waste enters the outer filter cylinder 201 for further separation, while larger waste is discharged through the middle discharge ring 213. The waste falling into the outer filter cylinder 201 can undergo the third separation. After three separations... The smallest waste material is discharged through funnel 13, while the larger waste material is discharged through the outer discharge ring 206, completing multiple separations of waste material. Simultaneously, when waste material is placed inside the inner filter cylinder 214, it falls towards the inner discharge ring 217 from within the inner filter cylinder 214. As the inner filter cylinder 214 rotates, the baffle plate 218 blocks the flow, preventing the waste material from rolling down too quickly inside. Multiple inner support blocks 215 are fixedly connected to the outside of the inner filter cylinder 214. These blocks engage with the middle layer clips 212, allowing the inner filter cylinder 214 to be installed inside the middle layer filter cylinder 207. Multiple clamping plates are fixedly connected to one end of the outer surface of the inner filter cylinder 214. The inner filter cylinder 214 has an inner discharge ring 217 fixedly connected to its other end. An inner support block 215 engages with a middle layer clamping ear 212. A second clamping plate 216 engages with a clamping groove 209. When the second clamping plate 216 engages inside the clamping groove 209, it forms a relatively sealed ring with the middle layer retaining ring 208. This prevents waste from falling between the inner filter cylinder 214 and the middle layer filter cylinder 207 when waste is added to the inner filter cylinder 214. Multiple baffle plates 218 are fixedly connected to the inner side of the inner filter cylinder 214. These baffle plates 218 prevent waste from rolling down rapidly, avoiding incomplete separation due to excessive waste falling. An auxiliary stabilizing wheel is also included. The outer part of the 10 contacts the groove of the ring rail 202, the outer part of the power wheel 9 contacts the groove of the ring rail 202, and one end of the outer filter cylinder 201 contacts multiple mounting blocking wheels 11. When assembling the outer filter cylinder 201, the middle filter cylinder 207, and the inner filter cylinder 214, first align the first locking plate 210 on the middle filter cylinder 207 with the locking groove 204, and align the middle support locking block 211 with the outer locking ear 205. At this time, slide the middle filter cylinder 207 into the interior of the outer filter cylinder 201. When the first locking plate 210 engages with the locking groove 204 and the middle support locking block 211 engages with the outer locking ear 205, the assembly of the middle filter cylinder 207 and the outer filter cylinder 201 can be completed. When the second locking plate 216 is aligned with the engaging groove 209...After the inner support block 215 is aligned with the middle layer retaining lug 212, the inner filter cylinder 214 is slid into the middle layer filter cylinder 207, causing the second retaining plate 216 to engage inside the engaging groove 209. With the inner support block 215 engaged inside the middle layer retaining lug 212, the inner filter cylinder 214 and the middle layer filter cylinder 207 are combined. At this point, the second retaining plate 216 and the middle layer retaining ring 208, and the first retaining plate 210 and the retaining groove 204 form a sealing surface. Therefore, adding separation waste to the inner filter cylinder 214 prevents the waste from falling directly into the middle layer filter cylinder 207 and the outer filter cylinder 201.

[0031] The vibration mechanism 3 includes two mounting plates 301, which provide mounting positions. The two mounting plates 301 are respectively fixedly connected to both sides of the central crossbar of the placement frame 1. A rotating plate 302 is rotatably connected to the top of the mounting plates 301. The rotating plate 302 serves a connecting function and provides the mounting position. A roller 303 is rotatably connected to the top of the rotating plate 302. The roller 303 can strike the outer wall of the outer filter cartridge 201, thereby causing vibration. A rotating cylinder 304 is rotatably connected to one end of the mounting plates 301, providing the mounting position. A compression spring 305 is installed inside the rotating cylinder 304. A limiting disc 306 is slidably connected inside the rotating cylinder 304, serving a limiting function. A movable rod 307 is fixedly connected to the top, and the movable rod 307 can be connected to the rotating plate 302. When the compression spring 305 pushes the limiting plate 306 upward, it can drive the movable rod 307 upward, and drive the rotating plate 302 to rotate upward, thereby driving the roller 303 to move upward and strike the outer wall of the outer filter cylinder 201. The top of the movable rod 307 is rotatably connected to the inside of the rotating plate 302. Multiple compression teeth 308 are fixedly connected to both sides of the middle part of the outer filter cylinder 201. One side of the compression tooth 308 is inclined, and the other side is vertical. When the inclined surface pushes the roller 303, it can squeeze the roller 303 to rotate downward. When the roller 303 moves to the vertical surface of the compression tooth 308, it can squeeze the spring. Under the reaction force of 305, it rotates rapidly upward, causing roller 303 to strike the outer wall of outer filter cylinder 201. One end of compression spring 305 is fixedly connected to the inside of rotating cylinder 304, and the other end of compression spring 305 is fixedly connected to the bottom of limiting plate 306. Movable rod 307 passes through the top of rotating cylinder 304. The outside of roller 303 contacts the middle of outer filter cylinder 201. When outer filter cylinder 201 rotates, it can drive compression tooth 308 to rotate. Since one side of compression tooth 308 is inclined, when compression tooth 308 rotates, the inclined surface will first contact roller 303. After roller 303 contacts the inclined surface of compression tooth 308, it can squeeze roller 303, causing roller 305 to strike the outer wall of outer filter cylinder 201. 3. The rotating plate 302 rotates downwards, which in turn pushes the movable rod 307 downwards and moves the limiting plate 306 downwards. This allows the limiting plate 306 to compress the compression spring 305. When the roller 303 leaves the inclined surface of the compression tooth 308, the reaction force of the compression spring 305 pushes the limiting plate 306 and the movable rod 307 upwards, causing the rotating plate 302 to rotate upwards. This, in turn, causes the roller 303 to rotate upwards and strike the outside of the outer filter cylinder 201, generating vibration. The vibration of the outer filter cylinder 201 then transmits the force of the vibration to the middle filter cylinder 207 and the inner filter cylinder 214.This allows the waste material clogging the holes in the outer filter cartridge 201, the middle filter cartridge 207, and the inner filter cartridge 214 to be shaken off, preventing it from affecting the separation effect of the multi-layer separation mechanism 2.

[0032] The dust extraction mechanism 4 includes an installation cylinder 401, which provides an installation position. An installation bracket 410 is fixedly connected to the outside of the installation cylinder 401, providing the installation position. The installation bracket 410 is externally fixedly connected to one end of the placement frame 1. A vent ring 402 is fixedly connected to one end of the installation cylinder 401, allowing airflow and providing the installation position. An installation disc 403 is fixedly connected to the inner side of one end of the installation cylinder 401, providing the installation position. A discharge cylinder 404 is fixedly connected to the outside of the vent ring 402, and the bottom of the discharge cylinder 404 can be connected to a dust handling device. A fan blade 4 is fixedly connected to the outside of the drive shaft 7. 05. The fan blade 405 can rotate under the action of the drive shaft 7 and generate suction to draw dust into the vent ring 402, so that it can be discharged through the discharge cylinder 404. The top of the mounting cylinder 401 is fixedly connected to the suction hose 406, which has a connecting function. The top of the two baffles 12 is fixedly connected to the shield 407, which provides the installation position. The inner side of the shield 407 is fixedly connected to the dust collection plate 408, which can expand the dust collection area. The top of the two shields 407 is fixedly connected to the dust collection connecting pipe 409, which can connect to the dust collection plate 408 and can be connected to the dust collection connecting pipe 409. Pipe 409 and suction hose 406 transport dust to the interior of mounting cylinder 401. The other end of suction hose 406 is fixedly connected to one end of suction pipe 409. One end of motor 6 is fixedly connected to the side of mounting plate 403 away from fan blade 405. One end of drive shaft 7 is rotatably connected to the middle of one end of mounting cylinder 401, and the other end of drive shaft 7 is rotatably connected to the middle of mounting plate 403. Fan blade 405 is located inside mounting cylinder 401. The interior of ventilation ring 402 is connected to the interior of mounting cylinder 401. When the output end of motor 6 rotates, it can drive drive shaft 7 to rotate. Since the speed of drive shaft 7 is not reduced by reducer 5, drive shaft 7... The high rotation speed of the fan blades 405 drives the fan blades 405 to rotate. The rotation of the fan blades 405 generates wind and creates suction inside the mounting cylinder 401 near the reducer 5. The suction is transmitted to the dust extraction connecting pipe 409 through the suction hose 406, and then to the dust extraction plate 408 through the dust extraction connecting pipe 409. The dust extraction plate 408 can suck in the fine dust generated when the outer filter cylinder 201 rotates and enter the mounting cylinder 401. The dust is then blown into the ventilation ring 402 and discharged through the discharge cylinder 404. The bottom of the discharge cylinder 404 can be connected to a dust filtration device to filter the dust.

[0033] Working principle: After the multi-layer separation mechanism 2 is placed on top of the placement frame 1, the ring rail 202 on the outer filter cylinder 201 can be placed on the power wheel 9 and the auxiliary stabilizing wheel 10. The end of the outer filter cylinder 201 near the outer discharge ring 206 abuts against the mounting blocking wheel 11. Since the placement frame 1 is lower at the end of the outer discharge ring 206, part of the weight of the multi-layer separation mechanism 2 falls on the mounting blocking wheel 11. Therefore, the multi-layer separation mechanism 2 can be placed on top of the placement frame 1. After the motor 6 is started, it can... The drive shaft 7 can rotate, which in turn drives the reducer 5. The reducer 5 then transmits the power via a belt to drive the drive rod 8, which in turn drives the power wheel 9. The power wheel 9 then drives the ring rail 202, which in turn drives the outer filter cartridge 201. The middle filter cartridge 207 is installed inside the outer filter cartridge 201, and the inner filter cartridge 214 is installed inside the middle filter cartridge 207. Therefore, when the outer filter cartridge 201 rotates, it can... The system can rotate the middle filter cylinder 207 and the inner filter cylinder 214. When roadbed waste to be separated is placed into the inner filter cylinder 214, the inner filter cylinder 214 can perform the first separation. Smaller waste falls onto the middle filter cylinder 207, while larger waste is discharged through the inner discharge ring 217. The waste falling onto the middle filter cylinder 207 undergoes a second separation; smaller waste enters the outer filter cylinder 201 for further separation, while larger waste is discharged through the middle discharge ring 213. The waste entering the outer filter cylinder 201 can undergo a third separation. After three separations, the smallest waste is discharged through the funnel 13, while the larger waste is discharged through the outer discharge ring 206, thus completing the multiple separations of the waste. At the same time, when the waste is put into the inner filter cylinder 214, the waste falls into the inner discharge ring 217 from the inside of the inner filter cylinder 214. When the inner filter cylinder 214 rotates, the baffle plate 218 blocks the waste to prevent it from rolling down the inner filter cylinder 214 too quickly.

[0034] When assembling the outer filter cartridge 201, the middle filter cartridge 207, and the inner filter cartridge 214, first align the locking plate 210 on the middle filter cartridge 207 with the locking groove 204, and align the middle support locking block 211 with the outer locking lug 205. Then slide the middle filter cartridge 207 into the interior of the outer filter cartridge 201. Once the locking plate 210 engages with the locking groove 204 and the middle support locking block 211 engages with the outer locking lug 205, the assembly of the middle filter cartridge 207 and the outer filter cartridge 201 is complete. Then, align the locking plate 216 with the engaging groove 209 and the inner support locking block 215... After aligning the middle layer clip 212, slide the inner filter cylinder 214 into the middle layer filter cylinder 207, so that the second clip 216 engages in the engagement groove 209 and the inner support clip 215 engages in the middle layer clip 212, thus completing the combination of the inner filter cylinder 214 and the middle layer filter cylinder 207. At this time, the second clip 216 and the middle layer retaining ring 208, the first clip 210 and the clip groove 204 form a sealing surface. Therefore, after adding the separated waste material to the inner filter cylinder 214, the waste material can be prevented from falling directly into the middle layer filter cylinder 207 and the outer filter cylinder 201.

[0035] When the outer filter cylinder 201 rotates, it drives the extrusion teeth 308 to rotate. Since one side of the extrusion teeth 308 is an inclined surface, when the extrusion teeth 308 rotates, the inclined surface will first contact the roller 303. After the roller 303 contacts the inclined surface of the extrusion teeth 308, it can squeeze the roller 303, causing the roller 303 to rotate downwards, and driving the rotating plate 302 to rotate downwards. After the rotating plate 302 rotates downwards, it can push the movable rod 307 downwards, and push the limiting plate 306 downwards, so that the limiting plate 306 can squeeze the extrusion spring 305. When the roller 303 leaves the extrusion teeth 308, the extrusion spring 305 rotates downwards. After the inclined plane of 08, the limiting plate 306 and the movable rod 307 can be pushed upward by the reaction force of the compression spring 305, and the rotating plate 302 can be pushed upward to rotate. Then, the roller 303 can be driven to rotate upward and strike the outside of the outer filter cylinder 201, thereby generating vibration. After the outer filter cylinder 201 vibrates, it can transmit the vibration force to the middle filter cylinder 207 and the inner filter cylinder 214, thereby shaking off the waste material blocked in the holes of the outer filter cylinder 201, the middle filter cylinder 207 and the inner filter cylinder 214, so as to avoid affecting the separation effect of the multi-layer separation mechanism 2.

[0036] When the output end of the motor 6 rotates, it drives the transmission shaft 7 to rotate. Since the speed of the transmission shaft 7 is not reduced by the reducer 5, the speed of the transmission shaft 7 is relatively fast, which in turn drives the fan blade 405 to rotate. After the fan blade 405 rotates, it can generate wind power and generate suction inside the mounting cylinder 401 near the reducer 5. The suction is transmitted to the dust extraction connecting pipe 409 through the suction hose 406, and then to the dust extraction plate 408 through the dust extraction connecting pipe 409. The dust extraction plate 408 can suck in the fine dust generated when the outer filter cylinder 201 rotates and enter the interior of the mounting cylinder 401. Then, the dust is blown into the interior of the ventilation ring 402 and discharged through the discharge cylinder 404. The bottom of the discharge cylinder 404 can be connected to a dust filtration device to filter the dust.
