Description

Technical Field

[0001] This invention relates to the field of waste product recycling technology, specifically a multi-stage waste product recycling system. Background Technology

[0002] With the rapid development of the electronics, hardware, and plastic products industries, the amount of waste products such as waste household appliances, waste metals, waste plastics, and scrapped components continues to grow, and the scale of the renewable resource recycling industry continues to expand. In order to realize the resource reuse of waste products, it is necessary to use recycling equipment to recycle and process waste products.

[0003] Existing waste product recycling equipment mainly consists of a screening mechanism and a crushing mechanism. When recycling waste materials, the waste materials are first crushed by the crushing mechanism and then screened by the screening mechanism to achieve the crushing, screening, and classification collection of waste materials.

[0004] The inventors of this application discovered in their research that the core defects of the aforementioned prior art are as follows: relying solely on a single vibrating screen to complete the screening and separation, lacking a matching turning and gravity separation structure, the mixed granular materials after screening are of varying weights and cannot be automatically separated into materials of different specific gravities such as metals and plastics, making it difficult to guarantee the purity of the recycled materials. During the screening process, it is impossible to perform simultaneous drying treatment, and waste products are prone to water stains and moisture adhering to them after long-term storage. Damp and fine granular materials are very easy to stick together and clump together, clogging the screen mesh and screen holes, resulting in poor material feeding during screening, frequent equipment shutdowns for cleaning, and reduced screening efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-stage waste product recycling system, which solves the problems of existing equipment relying solely on single screening, lacking a gravity-driven turning and sorting structure, resulting in low purity of mixed materials, inability to dry simultaneously, and easy clogging of screens by damp materials, thus affecting screening efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage waste product recycling system, comprising a housing, a hollow screen plate disposed within the housing, a guide hopper fixedly connected to the top of the hollow screen plate, a discharge port opened at the bottom of the hollow screen plate, a force-bearing head fixedly connected to the top of the hollow screen plate, a column installed on the top of the housing, a motor mounted on the top of the column, a swing rod fixedly connected to the output end of the motor, the other end of the swing rod disposed on one side of a slider, a rod hole opened on the top of the housing, a lifting rod slidably connected within the rod hole of the housing, a hammer fixedly connected to the bottom end of the lifting rod, a slide rail fixedly connected to the top end of the lifting rod, and a slider slidably connected within the slide rail; A linkage drying assembly is provided below the cavity screen plate, a turning and throwing assembly is provided on one side of the box, and a crushing assembly is provided on the other side of the box. The linkage drying assembly includes a sleeve.

[0007] By adopting the above technical solution, the motor drives the swing arm to perform circular motion, which is then converted into the up-and-down reciprocating motion of the lifting rod via the slider and slide rail transmission. The hammer periodically strikes the force-bearing head, and the spring rebound causes the hollow screen plate to vibrate at high frequency, achieving screening. The mechanical motion of the hollow screen plate in reciprocating screening is linked to the sleeve piston structure, eliminating the need for an additional drying drive motor. The up-and-down vibration of the screen plate drives the piston rod and piston block to reciprocate, which, in conjunction with the one-way valve, fan, and heating wire, forms a circulating hot air, simultaneously screening fine materials and completing hot air drying, removing impurities. The equipment effectively removes surface moisture from the material, preventing damp particles from sticking together and clumping, thus avoiding screen blockage. Multiple processes, including crushing, screening, drying, and sorting, are integrated into a single machine for continuous operation, eliminating material transfer and shortening the waste product recycling process. Simultaneously, the screening machinery is linked to a hot air system, reducing additional power consumption and lowering overall equipment energy consumption. Through multi-stage screening, this equipment can automatically separate large pieces of material, small particles, lightweight plastics, heavy metals, and other waste materials, reducing subsequent manual sorting workload and improving the purity of the recycled materials.

[0012] Preferably, a second motor is installed on one side of the cylinder, and the output end of the second motor is fixedly connected to one end of the rotating rod. An inlet and an outlet are respectively opened on the outer wall of the cylinder.

[0013] Preferably, the crushing assembly includes a crushing bucket, one side of which is fixedly connected to the other side of the housing. Two rotating shafts are rotatably connected inside the crushing bucket, and crushing rollers are fixedly connected to the outer walls of both rotating shafts.

[0016] Preferably, a discharge port is provided on one side of the box body, and the bottom end of the cavity screen plate is located inside the discharge port.

[0017] This invention provides a multi-stage waste product recycling system. It has the following beneficial effects: 1. This invention utilizes a mechanical motion linkage sleeve piston structure for reciprocating screening of a hollow screen plate, eliminating the need for an additional drying drive motor. The screen plate's up-and-down movement drives the piston rod and piston block to reciprocate, forming a circulating hot air cycle with the help of a one-way valve, fan, and heating wire. This process simultaneously screens fine materials and dries them with hot air, removing surface moisture, preventing damp particles from sticking together and clumping, and avoiding screen blockage. Multiple processes, including crushing, screening, drying, and sorting, are integrated into one machine for continuous operation, eliminating material transfer and shortening the waste product recycling process. Furthermore, the use of mechanical power linkage with the hot air system reduces additional power consumption and lowers the overall energy consumption of the equipment.

[0018] 2. This invention utilizes a multi-stage sorting mechanism. The first stage relies on the reciprocating lifting motion of the hollow screen plate to screen materials of different sizes. Larger materials are automatically discharged and can be recycled for further crushing, while smaller particles fall through the screen holes into the inner cavity of the hollow screen plate. The second stage involves throwing materials through a turning and throwing component, using the difference in specific gravity of small particles to achieve gravity sorting. Light and heavy materials automatically fall into the independently separated chambers of the collection box based on the throwing distance. This equipment can automatically screen large pieces of materials, small particles, lightweight plastics, heavy metals, and other waste materials, reducing the workload of subsequent manual sorting and improving the purity of the recycled materials.

[0019] 3. The present invention features a crushing on one side of the box, screening and drying in the middle, and turning and sorting collection on the other side. The whole machine adopts a compact integrated layout. After the material is crushed, it is automatically conveyed along the inclined plane to the screening, drying and sorting station. There is no need for manual material transfer throughout the process, which improves the overall processing efficiency of waste product crushing and recycling and is suitable for large-scale centralized recycling and processing scenarios of waste products.

[0022] The technical solution of the present invention will now be clearly and completely described 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.

[0023] Please see the appendix Figure 1 -Appendix Figure 7 This invention provides a multi-stage waste product recycling system, including a box 1, a hollow screen plate 2 inside the box 1, a guide hopper 201 fixedly connected to the top of the hollow screen plate 2, a discharge port 202 opened at the bottom of the hollow screen plate 2, a force-receiving head 203 fixedly connected to the top of the hollow screen plate 2, a column 204 installed on the top of the box 1, a motor 205 installed at the top of the column 204, a swing rod 206 fixedly connected to the output end of the motor 205, the other end of the swing rod 206 being located on one side of a slider 207, a rod hole opened at the top of the box 1, a lifting rod 209 slidably connected in the rod hole of the box 1, a hammer 210 fixedly connected to the bottom end of the lifting rod 209, a slide rail 208 fixedly connected to the top end of the lifting rod 209, and a slider 207 slidably connected in the slide rail 208; A linkage drying component is provided below the cavity screen plate 2, a turning and throwing component is provided on one side of the box body 1 and is located below the discharge port 202, and a crushing component is provided on the other side of the box body 1. The linkage drying component includes a sleeve 3.

[0024] Specifically, the crushed material slides down the slope of the crushing hopper 6 onto the surface of the hollow screen plate 2 inside the housing 1. The motor 205 is started, driving the swing arm 206 to rotate. During rotation, the swing arm 206 continuously pushes against the slider 207. The slider 207 slides back and forth inside the slide rail 208 at the top of the lifting rod 209, converting the circular motion of the swing arm 206 into the reciprocating lifting motion of the lifting rod 209. The hammer 210 at the bottom of the lifting rod 209 repeatedly strikes and presses down on the force-receiving head 203 at the top of the hollow screen plate 2. The bottom of the hollow screen plate 2 is elastically supported by the piston rod 302 and the spring 303. The hammer 210 presses down on the force-receiving head 203. At 03 o'clock, when the hollow screen plate 2 moves down and the hammer head 210 moves up, the spring 303 rebounds and drives the hollow screen plate 2 to reset upward, so that the hollow screen plate 2 as a whole vibrates at high frequency, which facilitates the rapid screening of materials. Large particles are intercepted by the surface of the hollow screen plate 2 and cannot pass through the screen holes. The intercepted large particles slide down the inclined slope of the hollow screen plate 2 into the guide hopper 201 and are discharged from one end of the guide hopper 201. The discharged large pieces of material can be put back into the crushing hopper 6 for secondary crushing. Small particles fall through the screen holes into the inner cavity of the hollow screen plate 2 and then fall through the discharge port 202 into the cylinder 401 of the turning and throwing component. A turning and turning component is set up to turn and turn the dried small particles of material, and a crushing component is set up to crush the waste material. The equipment features crushing on one side, screening and drying in the middle, and turning and sorting collection on the other side. The whole machine adopts a compact and integrated layout. After being crushed, the material is automatically conveyed along the inclined plane to the screening, drying and sorting stations. No manual material transfer is required throughout the process, which improves the overall processing efficiency of waste product crushing and recycling and is suitable for large-scale centralized recycling and processing scenarios.

[0025] Please see the appendix Figure 2 -Appendix Figure 3 Appendix Figure 6 -Appendix Figure 7 The bottom of the sleeve 3 is fixedly connected to the bottom inner wall of the box 1. A piston block 301 is provided inside the sleeve 3, and a piston rod 302 is fixedly connected to the top of the piston block 301. The top of the piston rod 302 is installed at the bottom of the cavity screen plate 2. A limit plate 304 is fixedly connected inside the box 1. A central hole is opened in the middle of the limit plate 304, and the piston rod 302 is slidably connected in the central hole. A spring 303 is fixedly connected to the opposite side of the piston block 301 and the limit plate 304. A connecting pipe 305 and a horizontal pipe 311 are fixedly connected to the two sides of the bottom end of the sleeve 3, respectively. The end of the horizontal pipe 311 away from the sleeve 3 is fixedly connected to a... The sleeve 312 is equipped with a fan 310 and an electric heating wire 309. The outer wall of the horizontal pipe 311 is equipped with a first one-way valve. The end of the connecting pipe 305 away from the sleeve 3 is fixedly connected to a connecting pipe 306. The outer wall of the connecting pipe 305 is equipped with a second one-way valve. Air outlets 307 are evenly fixedly connected to one side of the connecting pipe 306. The outer walls of the multiple air outlets 307 are fixedly connected to a movable plate 308. The inner wall of the movable plate 308 is fixedly connected to one side of the cavity screen plate 2. The air outlets 307 are connected to the inner cavity of the cavity screen plate 2. The inner wall of the movable plate 308 is slidably connected to the outer wall of the box 1.

[0026] Specifically, while the hollow screen plate 2 moves up and down, it simultaneously drives the piston rod 302, which is fixedly connected to the bottom, to move up and down. This, in turn, pushes the piston block 301 to move up and down within the sleeve 3. When the piston rod 302 moves the piston block 301 upward, the first one-way valve on the horizontal pipe 311 opens, and the second one-way valve on the connecting pipe 305 closes. At the same time, with the cooperation of the blower 310 and the heating wire 309, the heated gas is blown into the sleeve 3 through the horizontal pipe 311. When the piston rod 302 pushes the piston block 301 downward, the first one-way valve on the horizontal pipe 311 closes, and the second one-way valve on the connecting pipe 305 opens. The hot gas in the sleeve 3 flows into the connecting pipe 306 through the connecting pipe 305, and finally is evenly sprayed into the inner cavity of the hollow screen plate 2 through multiple air outlets 307. The hot gas comes into contact with the small particles, quickly removing the moisture attached to the surface of the material, completing the drying process, preventing the damp particles from sticking together and clumping, avoiding screen blockage, and ensuring the screening effect.

[0027] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 5 The turning and throwing assembly includes a support base 4, one side of which is fixedly connected to one side of the box body 1. A cylinder 401 is fixedly connected to the top of the support base 4. A rotating rod 402 is rotatably connected inside the cylinder 401. Turning and throwing plates 403 are evenly fixedly connected to the outer wall of the rotating rod 402. A second motor 404 is installed on one side of the cylinder 401. The output end of the second motor 404 is fixedly connected to one end of the rotating rod 402. An inlet 405 and an outlet 406 are respectively opened on the outer wall of the cylinder 401.

[0028] Specifically, the small granular material dried by hot air continuously falls from the feed port 202 and enters the cylinder 401 from the inlet 405 at the top of the cylinder 401. The motor 404 is started, driving the rotating rod 402 to rotate. The rotating rod 402 drives the turning plate 403 to rotate, thereby turning and throwing the small granular material. The turned material is thrown out through the outlet 406. Gravity separation is achieved by relying on the difference in the specific gravity of the material itself. The two collection chambers in the collection box 5 classify and collect materials of different weights respectively.

[0029] Please see the appendix Figure 1 -Appendix Figure 3The crushing assembly includes a crushing bucket 6, one side of which is fixedly connected to the other side of the housing 1. Two rotating shafts 601 are rotatably connected inside the crushing bucket 6. Crushing rollers 602 are fixedly connected to the outer walls of the two rotating shafts 601, and the crushing rollers 602 are disposed inside the crushing bucket 6. A driven gear 603 and a driving gear 604 are fixedly connected to one end of the two rotating shafts 601, respectively. The driving gear 604 and the driven gear 603 mesh with each other. A mounting base 605 is fixedly connected to the outer wall of the crushing bucket 6. A motor 606 is installed inside the mounting base 605. The output end of the motor 606 is fixedly connected to one end of one of the rotating shafts 601. An inclined plate 607 is provided inside the crushing bucket 6.

[0030] Specifically, the waste materials to be recycled are put into the crushing hopper 6, the motor 606 is started, and a rotating shaft 601 is driven to rotate. The drive gear 604 at the end of the rotating shaft 601 rotates synchronously. The drive gear 604 meshes with and drives the driven gear 603 to rotate synchronously in the opposite direction, so that the two rotating shafts 601 rotate in opposite directions. The crushing rollers 602 on the outer wall of the two rotating shafts 601 crush and shear synchronously in opposite directions, crushing the waste metal, plastic, electronic components and other waste products.

[0031] Please see the appendix Figure 1 -Appendix Figure 3 A collection box 5 is provided on the side of the box body 1. A connecting plate 502 is fixedly connected to the top side of the collection box 5. The side of the connecting plate 502 away from the collection box 5 is fixedly connected to the outer wall of the cylinder 401. The connecting plate 502 is located below the outlet 406. An arc-shaped baffle 501 is fixedly connected to the top of the collection box 5. An outlet 101 is opened on one side of the box body 1. The bottom end of the cavity screen plate 2 is located inside the outlet 101.

[0032] Specifically, when the tumbling plate 403 throws materials, the arc-shaped baffle 501 can block the splashing of particulate materials, limit the material throwing range, reduce material loss and dust pollution around the equipment, and improve the material recycling rate.

[0033] After being sorted by gravity, the light and heavy granular materials are automatically separated into two independent compartments inside the collection box 5 based on the difference in throwing distance, thus completing the partitioned collection of waste materials with different specific gravities and facilitating subsequent unified transportation and processing. The side wall of the box 1 has a discharge port 101. Larger materials that are intercepted slide down the slope of the cavity screen plate 2 and are discharged from the discharge port 101 into the guide hopper 201. The large pieces of material are finally discharged from the opening at one end of the guide hopper 201.

[0034] Work process: Put the waste materials into the crushing hopper 6, start the motor 606, drive one shaft 601 to rotate, the shaft 601 drives the drive gear 604 to rotate, the drive gear 604 meshes and drives the driven gear 603 to rotate in the opposite direction synchronously, thereby making the two shafts 601 synchronously drive the two crushing rollers 602 to rotate in opposite directions, thus completing the crushing process of the waste materials. The crushed material slides down the slope of the crushing hopper 6 onto the surface of the hollow screen plate 2 inside the housing 1. The motor 205 is started, driving the swing arm 206 to rotate. During rotation, the swing arm 206 continuously pushes against the slider 207. The slider 207 slides back and forth inside the slide rail 208 at the top of the lifting rod 209, converting the circular motion of the swing arm 206 into the reciprocating lifting motion of the lifting rod 209. The hammer 210 at the bottom of the lifting rod 209 repeatedly strikes and presses downwards against the force-bearing head 203 at the top of the hollow screen plate 2. Through the elastic support of piston rod 302 and spring 303, when hammer 210 presses down on force-bearing head 203, hollow screen plate 2 moves down. When hammer 210 moves up, spring 303 rebounds and drives hollow screen plate 2 to reset upward, realizing high-frequency reciprocating shaking of hollow screen plate 2 as a whole. Large particles are intercepted and slide down the surface of hollow screen plate 2 into guide hopper 201 and are discharged from one end of guide hopper 201. Small particles fall through the screen holes into the inner cavity of hollow screen plate 2 and fall into cylinder 401 through discharge port 202. While the hollow screen plate 2 moves up and down, it simultaneously drives the piston rod 302, which is fixedly connected to the bottom, to move up and down. When the piston rod 302 rises, the first one-way valve on the horizontal pipe 311 opens and the second one-way valve on the connecting pipe 305 closes. With the cooperation of the fan 310 and the heating wire 309, the heated gas is blown into the sleeve 3 through the horizontal pipe 311. When the piston rod 302 moves down, the first one-way valve on the horizontal pipe 311 closes and the second one-way valve on the connecting pipe 305 opens. The hot gas in the sleeve 3 flows into the connecting pipe 306 through the connecting pipe 305 and is finally evenly sprayed into the inner cavity of the hollow screen plate 2 through multiple air outlets 307 to dry small particles. The small granular material dried by hot air falls continuously from the feed port 202 and enters the cylinder 401 from the inlet 405 at the top of the cylinder 401. The motor 404 is started, driving the rotating rod 402 to rotate. The rotating rod 402 drives the turning plate 403 to rotate, turning and throwing the small granular material. The turned material is thrown out through the outlet 406. Gravity separation is achieved by relying on the difference in the specific gravity of the material. The two collection chambers in the collection box 5 collect materials of different weights separately.
