Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, and in particular to a solid waste recycling and processing equipment and method for the production of anti-impact safety shoes. Background Technology

[0002] The footwear manufacturing industry generates a large amount of waste during production, mainly consisting of solid waste made of various materials such as metal toe caps, fibers / leather, rubber, EVA, and PU. If this waste is disposed of indiscriminately, it not only occupies significant storage and landfill space, but its chemical components may also seep into the soil and pollute water sources, posing a potential threat to the ecological environment. Furthermore, shoe sole raw materials are mostly non-renewable resources, and wasting waste means a reduction in resource utilization. Therefore, the footwear industry generally emphasizes waste recycling and processing, using processes such as sorting, crushing, grinding, and high-temperature melting to transform waste into recycled raw materials that can be reused in the production of shoe sole base materials or the processing of other industrial products.

[0003] Existing technologies typically employ a series of processes—crushing, magnetic separation, air separation, and flotation—but these methods suffer from several drawbacks in practical applications, resulting in poor separation efficiency and purity. Firstly, in the magnetic separation stage, traditional fixed or linear magnetic separators easily trap non-metallic materials (such as fabrics and rubber) between metallic materials and the magnetic source, leading to low purity of the recovered metal and loss of valuable non-metallic materials. Secondly, in the air separation stage, due to the accumulation of falling material streams, the airflow from fixed outlets is easily blocked by the upper layer of heavy materials, creating "air separation dead zones." This results in some lighter materials failing to be effectively separated and mixing into subsequent processes. Thirdly, in buoyancy separation (such as brine flotation), during the settling and floating process in the solution, the sinking trajectory of heavy materials can interfere with, compress, or even engulf medium and light materials, preventing them from reaching the theoretical stratification position. Simultaneously, traditional scraper or spiral discharge methods, when separating materials from different liquid layers, also inevitably cause secondary disturbance to the already stratified materials, affecting the final separation accuracy. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a solid waste recycling and processing equipment and method for the production of anti-impact safety shoes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A solid waste recycling and processing device for the production of anti-impact safety shoes includes a frame and further includes:

[0007] A crushing bin is located at the top of the frame. Two crushing rollers rotate in opposite directions inside the crushing bin. A drive unit for driving the crushing rollers is provided on the frame.

[0008] A gold removal box is located below the shredder and connected to the shredder by a feeding hopper. The gold removal box is equipped with a gold removal component for removing metal and a metal hopper for receiving metal materials.

[0009] An air classifier is fixed at the bottom of the gold removal box and connected to its bottom outlet. An air classifier assembly is provided on one side of the air classifier, and a lightweight material box that cooperates with the air classifier assembly and is connected to the air classifier is provided on the other side.

[0010] And a buoyancy sorting box, which is set at the bottom of the air classifier and connected to its bottom discharge port, is provided with several sets of separating components to separate rubber waste with different buoyancy.

[0011] Preferably, the drive unit includes a drive motor fixed on the frame, a gearbox connected to the output shaft of the drive motor, and movable gears respectively disposed on the two crushing rollers and meshing with each other, wherein the output shaft of the gearbox is connected to the roller body of one of the crushing rollers.

[0012] Preferably, the gold removal assembly includes a rotating seat rotatably disposed inside the gold removal box and several groups of gold removal parts evenly disposed on the rotating seat in a circular pattern. Each group of gold removal parts is provided with at least three electromagnet rods extending outward from the rotating seat. The frame is provided with a transmission assembly for driving the rotating seat to rotate.

[0013] Preferably, the transmission assembly includes a transmission rod rotatably mounted on the frame, a secondary bevel gear mounted on the transmission rod, a main bevel gear fixed on the output shaft of the transmission and meshing with the secondary bevel gear, synchronous pulleys respectively mounted on the transmission rod and the top shaft of the rotating seat, and a synchronous belt mounted between the two synchronous pulleys.

[0014] Preferably, a support plate is fixed inside the gold removal box, the rotating seat is rotatably mounted on the top of the support plate, and a control component for controlling the operation of the gold removal section is provided on the support plate.

[0015] The control component includes an arc-shaped platform fixed on the support plate and elastic push switches located at the bottom of the rotating seat and corresponding to several groups of gold removal parts. Guide surfaces are provided on both sides of the arc-shaped platform, and the arc-shaped platform is located on the side of the support plate away from the metal hopper.

[0016] Preferably, the air separation assembly includes an arc-shaped plate disposed on the outside of the air separation box, a mounting plate fixed on the lower side of the arc-shaped plate, a fan disposed on the mounting plate, and an air outlet connected to the fan's air outlet pipe.

[0017] The air outlet section includes a vertical pipe connected to the air outlet pipe of the fan, three branch pipes distributed sequentially along the axial direction of the vertical pipe, and an exhaust plate disposed at the end of each branch pipe, with an exhaust hole provided on each exhaust plate.

[0018] Preferably, a first connecting plate is fixed at the bottom of the transmission rod, and a second connecting plate is hinged between the first connecting plate and the mounting plate. The arc-shaped plate slides on the outside of the air separator box via a slider.

[0019] Preferably, a piston block is slidably connected inside the vertical pipe, and a through hole is opened on the piston block to cooperate with the middle diversion pipe. A slide rod is provided on the top of the piston block and slidably connected to the vertical pipe. A return spring is provided between the end of the slide rod and the outer wall of the vertical pipe. A support plate is fixed on the outside of the air separator, and a number of arc-shaped protrusions are provided on the support plate that move against the top of the slide rod.

[0020] Preferably, each of the separating components includes several swing plates rotatably disposed in the buoyancy sorting box via a rotating shaft, a connecting plate slidably connected to the outside of the buoyancy sorting box, and a telescopic plate fixed on the rotating shaft and hinged to the connecting plate. Movable plates are connected between the connecting plates of the multiple separating components, and an electric push rod for driving the displacement of the movable plate is fixedly disposed on the buoyancy sorting box.

[0021] The buoyancy sorting box is also connected to a liquid storage tank via a guide pipe, and a valve body is installed on the guide pipe.

[0022] This invention also discloses a method for recycling and processing solid waste from the production of anti-impact safety shoes. The method involves using the aforementioned equipment for recycling and processing solid waste from the production of anti-impact safety shoes, and includes the following steps:

[0023] S1: Pour the solution of the adjusted density into the buoyancy separation box, check whether each mechanism is normal, and then start the drive motor and fan;

[0024] S2: The waste material from the production of anti-smashing safety shoes is put into the crushing bin, and two relatively rotating crushing rollers crush the waste material into small pieces;

[0025] S3: The crushed waste enters the gold removal box through the hopper. The rotating gold removal part adsorbs metal below the gold removal box inlet. When it rotates to the top of the metal box, it automatically demagnetizes and releases the metal, completing the automatic and pure recovery of the metal.

[0026] S4: Non-metallic materials fall into the air separator, and the oscillating air outlet blows lightweight fabric and leather waste into the lightweight material box. The oscillation and concentrated spray of the air force ensure that there are no dead corners in the separation.

[0027] S5: The remaining materials enter the buoyancy sorting box. During the feeding process, the electric push rod is activated to reciprocate and extend, so that the multi-layer swing plate swings slowly to prevent heavy materials from pressing on light materials.

[0028] After stopping the feeding, allow the material to fully separate into layers according to density in the static solution, at which point the electric actuator stops working;

[0029] S6: After the settling is complete, control the electric push rod to extend and rotate all the swing plates to a horizontal position to form a multi-layer complete flat tray to receive the materials of each layer.

[0030] The solution in the buoyancy sorting box is pumped back to the storage tank through the guide pipe. The side door is opened, and the rubber waste of different densities that have been sorted are taken out from the swing plates of each layer.

[0031] Compared with the prior art, the present invention provides a solid waste recycling and processing device and method for the production of anti-impact safety shoes, which has the following beneficial effects:

[0032] 1. This invention, through the synergy of a dynamic gold removal component, a swing-type air separation component, and an anti-disturbance buoyancy separation component, sequentially solves three core problems during metal recycling: non-metal entrainment during metal recovery, heavy materials obscuring light materials during air separation, and heavy materials sinking and pressing down on light materials during flotation. This ensures the classification purity and recovery rate of metals, lightweight materials (such as fabric / leather), and rubber materials of different densities (such as EVA / PU and heavy rubber), achieving high-precision material separation throughout the entire process and effectively solving the problems of material entrainment and interference in traditional processes.

[0033] 2. This invention achieves "one machine, multiple actions" by having the on / off state of the gold removal section, the oscillation of the air separation section, and the air force distribution all driven by a single drive source through transmission components and linkage mechanisms. This not only simplifies the electrical control system but also ensures precise synchronization of the actions of each process, enabling the entire recycling process from crushing, gold removal, air separation to flotation to operate continuously, automatically, and efficiently, thereby improving the level of automation and operating efficiency.

[0034] 3. In the air separation stage, the constant air volume of the blower is periodically concentrated and distributed to one of the three air outlets (upper, middle, and lower) by the reciprocating movement of the piston block in the vertical pipe. This generates a high-speed, concentrated airflow intermittently while maintaining constant power, greatly enhancing the blowing capacity for lightweight materials. It overcomes the shortcomings of the dispersed airflow in traditional uniform flow air separation, optimizes the energy utilization and effect in the separation process, and improves the efficiency and thoroughness of air separation.

[0035] 4. In this invention, the multi-layered swingable partition plates inside the buoyancy sorting box swing during the material settling stage to prevent mutual interference, and can rotate synchronously after stratification to form a horizontal interception plane. This achieves "in-situ stratification, in-situ solid-liquid separation, and in-situ stratified material collection in solution," avoiding secondary disturbance to the already stabilized stratified material caused by mechanical discharge methods such as scrapers and spirals. As a result, it is possible to obtain various types of rubber waste with extremely high purity and stratified by density, providing a foundation for subsequent high-value recycling and ensuring the final accuracy of the sorting results.

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0049] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0050] like Figures 1 to 4 As shown, this embodiment proposes a solid waste recycling and processing device for the production of anti-impact safety shoes, including a frame 1, and further comprising:

[0051] The crushing box 2 is located on the top of the frame 1. Two crushing rollers 201 that rotate relative to each other are installed inside the crushing box 2. The frame 1 is provided with a drive unit for driving the crushing rollers 201 to work.

[0052] The gold removal box 3 is located below the crushing box 2 and is connected to the crushing box 2 by a feeding hopper 4. The gold removal box 3 is equipped with a gold removal component for removing metal and a metal hopper 5 for receiving metal materials.

[0053] The air classifier 6 is fixed at the bottom of the gold removal box 3 and connected to its bottom outlet. An air classifier assembly is provided on one side of the air classifier 6, and a lightweight material box 7 is provided on the other side, which cooperates with the air classifier assembly and is connected to the air classifier 6.

[0054] And a buoyancy sorting box 8, which is located at the bottom of the air classifier 6 and connected to its bottom discharge port. The buoyancy sorting box 8 is equipped with several sets of separating components to separate rubber waste with different buoyancy.

[0055] Specifically, waste materials from the production of anti-smashing safety shoes are fed into the top crushing bin 2. The drive unit is activated, causing the two crushing rollers 201 to rotate relative to each other, tearing and crushing the waste into small pieces. The crushed small pieces fall into the gold removal bin 3 through the feed hopper 4. During the flow of the material through the gold removal bin 3, the gold removal components inside generate magnetic force, adsorbing and separating the metal parts (such as anti-smashing toe caps, metal linings, shoe nails, etc.) in the material. The separated metal falls off or is scraped off at specific locations and collected in the metal bin 5, preventing it from damaging the subsequent air separation and flotation equipment, while ensuring operational safety. The non-metallic material after metal removal continues to fall and enters the air separation bin 6 from the bottom of the gold removal bin 3. The air separation component is activated, and air is sent from one side of the air separation bin 6 to the other side. The airflow blows up the components with low density and light weight (such as fabric fibers, leather scraps, foamed plastic scraps, etc.) in the material and blows them laterally to the other side of the air separation bin 6. The waste is collected in the lightweight material bin 7 on the side. The denser rubber materials (such as rubber outsoles, TPU, EVA, PU, ​​etc.) that are not blown away fall directly from the bottom of the air classifier 6 into the solution in the buoyancy separation bin 8. Due to their different densities, the waste materials exhibit different floating and sinking states in the solution (sinking, suspending, floating). At this time, the separation component is operated to divide the internal space of the buoyancy separation bin 8 into several areas in the vertical direction, thereby physically separating the various types of rubber waste that are at different heights and have been stratified according to density. Finally, the materials in each area are taken out separately, thus realizing the classified recycling of high-density rubber, medium-density foam materials, etc. The equipment integrates the recycling processes of crushing, gold removal, air classification, and flotation into one set of equipment. The materials flow automatically from top to bottom by gravity, eliminating the need for manual transfer between processes, which significantly improves processing efficiency and reduces labor costs and labor intensity.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the drive unit further includes a drive motor 9 fixed on the frame 1, a gearbox 901 connected to the output shaft of the drive motor 9, and a movable gear 902 disposed on the bodies of the two crushing rollers 201 and meshing with each other. The output shaft of the gearbox 901 is connected to the body of one of the crushing rollers 201.

[0057] Specifically, the rotational power output by the drive motor 9 is directly transmitted to the gearbox 901 connected to it through its output shaft. The gearbox 901 converts the input speed and torque into parameters suitable for material crushing according to the preset speed ratio and outputs them from its output shaft. The output shaft of the gearbox 901 directly drives the crushing roller 201 connected to it to start rotating through a mechanical connection. As the active crushing roller 201 rotates, the movable gear 902 installed at the end of its roller body meshes with the movable gear 902 installed at the end of the roller body of another crushing roller 201. The two crushing rollers 201 start to rotate in the same speed but opposite directions, biting, squeezing and shearing the material fed into the crushing box 2 to complete the crushing operation.

[0058] like Figure 5 , Figure 6 and Figure 7 As shown, in a preferred embodiment, based on the above method, the gold removal component further includes a rotating seat 10 rotatably disposed in the gold removal box 3 and several groups of gold removal parts 11 evenly disposed on the rotating seat 10 in a circular pattern. Each group of gold removal parts 11 is provided with at least three electromagnet rods extending outward from the rotating seat 10. A transmission component for driving the rotating seat 10 to rotate is provided on the frame 1.

[0059] Furthermore, the transmission assembly includes a transmission rod 12 rotatably mounted on the frame 1, a secondary bevel gear 121 mounted on the transmission rod 12, a main bevel gear 122 fixed on the output shaft of the transmission 901 and meshing with the secondary bevel gear 121, synchronous pulleys 123 respectively mounted on the top shaft of the transmission rod 12 and the rotating seat 10, and a synchronous belt mounted between the two synchronous pulleys 123.

[0060] Furthermore, a support plate 13 is fixedly installed inside the gold removal box 3, and a rotating seat 10 is rotatably mounted on the top of the support plate 13. A control component for controlling the operation of the gold removal unit 11 is provided on the support plate 13.

[0061] The control components include an arc-shaped platform 131 fixed on the support plate 13 and an elastic push switch 132 located at the bottom of the rotating seat 10 and corresponding to a number of gold removal parts 11. Guide surfaces are provided on both sides of the arc-shaped platform 131, and the arc-shaped platform 131 is located on the side of the support plate 13 away from the metal hopper 5.

[0062] Specifically, when the drive motor 9 starts and drives the crushing roller 201 through the transmission 901, the main bevel gear 122 and the secondary bevel gear 121, which are fixed on the output shaft of the transmission 901, mesh, driving the transmission rod 12 to rotate. The rotation of the transmission rod 12 is then transmitted through a pair of synchronous pulleys 123 and a synchronous belt, ultimately driving the rotating seat 10 to rotate at a constant speed on the support plate 13. This eliminates the need for a separate motor for the gold removal assembly, reducing costs. More importantly, it ensures strict synchronization between the crushing operation and the gold removal rotation. As the rotating seat 10 rotates, several groups of gold removal sections 11 evenly distributed on it pass through the feed box 3 in sequence. In the area where the gold removal unit 11 rotates to the area where the arc-shaped platform 131 is located, the elastic push switch 132 located at the bottom of the rotating seat 10 corresponding to the gold removal unit 11 is continuously pressed by the upper surface of the arc-shaped platform 131 under the guidance of the guide surface. The switch is pressed, the circuit is turned on, and the electromagnet rod of the gold removal unit 11 is energized, generating a strong magnetic field. This attracts the metal waste from the material flow falling from above onto the electromagnet rod. Since the metal is attracted to the circumference of the circular rod rather than the plane, when the rotating seat 10 rotates with the attracted metal, the metal material, under the slight action of centrifugal force and gravity, tends to move around the rod. The slight swaying tendency helps to shake off and detach non-metallic lightweight materials, such as cloth scraps and rubber particles, that may be "clamped" in the process of adsorption, thereby significantly improving the purity of the metal material falling into the metal bin 5. As the metal removal section 11, which has adsorbed the metal waste, continues to rotate with the rotating base 10, when it rotates to the upper area of ​​the metal bin 5 carrying the metal, the trigger end of the elastic push switch 132 at its bottom moves out of the range of the arc-shaped platform 131. The switch loses its squeezing force and resets under its own elastic force, the circuit is cut off, and the electromagnet rod of the metal removal section 11 is instantly de-energized and demagnetized. The metal waste, no longer magnetically adsorbed, is then... Under its own gravity, it falls cleanly into the metal bin 5 below, completing the collection. After the gold removal unit 11 is released, it continues to rotate. When the elastic push switch 132 at its bottom passes through the guide surface on the other side of the arc-shaped platform 131 and is squeezed again, the circuit is turned on again, and the electromagnet rod is energized again, preparing for the next rotation to the feeding area to adsorb metal. The cycle of "adsorption-transportation-release-reset" is carried out automatically and periodically as the rotating seat 10 continues to rotate. The entire gold removal process does not require manual intervention or complex electronic control programs, and has a high degree of automation, ensuring that the metal is reliably collected in the designated position.

[0063] like Figure 5 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the air separation component further includes an arc-shaped plate 14 disposed on the outside of the air separation box 6, a mounting plate 141 fixed on the lower side of the arc-shaped plate 14, a fan 142 disposed on the mounting plate 141, and an air outlet connected to the air outlet pipe of the fan 142.

[0064] The air outlet section includes a vertical pipe 15 connected to the air outlet pipe of the fan 142, three branch pipes 151 distributed sequentially along the axial direction of the vertical pipe 15, and an exhaust plate 152 provided at the end of each branch pipe 151. Each exhaust plate 152 is provided with an exhaust hole.

[0065] Furthermore, a first connecting plate 16 is fixedly provided at the bottom of the transmission rod 12, and a second connecting plate 161 is hinged between the first connecting plate 16 and the mounting plate 141. The arc plate 14 slides on the outside of the air separator 6 via a slider.

[0066] Furthermore, a piston block 17 is slidably connected inside the vertical pipe 15. The piston block 17 has a through hole that cooperates with the middle diversion pipe 151. The top of the piston block 17 is provided with a slide rod 171 that is slidably connected to the vertical pipe 15. A return spring is provided between the end of the slide rod 171 and the outer wall of the vertical pipe 15. A support plate 18 is fixedly provided on the outside of the air separator 6. Several protrusions 181 that are arc-shaped and move against the top of the slide rod 171 are provided on the support plate 18. The end of the slide rod 171 should be set as a conical platform that moves against the protrusion 181. The two sides of the protrusion 181 are set as inclined surfaces or arc surfaces.

[0067] Specifically, when the transmission rod 12 rotates, the first connecting plate 16 at its bottom moves in a circular motion. Through the hinge of the second connecting plate 161, the circular motion of the first connecting plate 16 is converted into the reciprocating arc sliding of the mounting plate 141 and the entire air separation assembly fixed thereon along the outer wall of the air separation box 6. This causes the exhaust plate 152 to periodically oscillate on the side wall of the inlet of the air separation box 6, thereby scanning a fan-shaped area, eliminating the dead angle of air separation at the fixed outlet, and effectively solving the problem of the "leeward side" caused by material stacking and uneven distribution. The issue of "wind shadow zone" is addressed to ensure that all lightweight materials have a chance to be captured by the airflow, reducing missed selection. During the aforementioned oscillation process, when the air separation component slides to a specific position, causing the top of the slide rod 171 to contact the inclined surface of the protrusion 181 on the support plate 18, the protrusion 181 will squeeze the slide rod 171. The slide rod 171 overcomes the elastic force of the return spring, causing the piston block 17 to slide within the vertical pipe 15. The movement of the piston block 17 will change the connection state between the air outlet pipe of the blower 142 and the three branch pipes 151 through the vertical pipe 15. When the wind... As the selected component continues to swing, after the slide bar 171 passes the protrusion 181, under the action of the return spring, the slide bar 171 drives the piston block 17 to return to its original position, and the airflow path switches accordingly. The through hole on the piston block 17 is only connected to the middle diverter pipe 151. When the piston block 17 moves down to the lowest position, the air outlet pipe of the fan 142 is only connected to the upper diverter pipe 151. When the piston block 17 moves up to return to the high position, the air outlet pipe of the fan 142 is only connected to the lower diverter pipe 151. When the through hole of the piston block 17 is only connected to one diverter pipe 151... When aligned, all the air volume generated by the fan 142 will be discharged through the exhaust plate 152 at the end of the split pipe 151, forming a concentrated and high-speed airflow. The two actions of swinging and airflow distribution are triggered synchronously by the same mechanical system. The swinging ensures that there are no dead angles in the airflow coverage, while the periodic concentrated airflow distribution ensures that the airflow is concentrated at one outlet at any time, obtaining a stronger instantaneous blowing force to enhance the blowing capacity of lightweight materials. The two work together to achieve more efficient and thorough air separation of the falling material flow.

[0068] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, each group of separating components further includes several swing plates 19 rotatably disposed in the buoyancy sorting box 8 via a rotating shaft, a connecting plate 191 slidably connected to the outside of the buoyancy sorting box 8, and a telescopic plate 192 fixed on the rotating shaft and hinged to the connecting plate 191. Movable plates 193 are connected between the connecting plates 191 of multiple groups of separating components, and an electric push rod 194 for driving the displacement of the movable plate 193 is fixedly disposed on the buoyancy sorting box 8.

[0069] The buoyancy separation box 8 is also connected to the liquid storage tank 20 through a guide pipe, and a valve body is installed on the guide pipe;

[0070] Specifically, the heavier waste material after air separation falls into the solution in the buoyancy separation tank 8. The buoyancy separation tank 8 contains a liquid medium, such as brine of a specific concentration. At this time, all the swing plates 19 are in the open state, for example, hanging vertically, providing sufficient falling space for materials of different densities, so that they can stably stratify according to density differences after settling. The heavy material sinks to the bottom of the tank, the light material floats on the surface, and the medium material is suspended in the middle layer. After the materials have been fully stratified, the electric push rod 194 is activated. The push rod of the electric push rod 194 extends or retracts, driving the movable plate 1 93 moves linearly, and the movable plate 193 drives all the connecting plates 191 to slide synchronously. The sliding of each connecting plate 191, through the telescopic plate 192 hinged to it, drives all the swing plates 19 in the same group to rotate synchronously around their axis. By precisely positioning the stroke of the electric push rod 194, the swing plates 19 of each layer can be rotated to a horizontal state, and the edges of multiple swing plates 19 in the same layer abut against each other, thereby forming multiple complete, horizontal interception planes inside the buoyancy sorting box 8. Each plane is located at the boundary of material layers with different densities. Below, the material in that layer is supported; once all the material in each layer is supported by the horizontal swing plate 19 below, the valve on the guide pipe connecting to the storage tank 20 is opened, and the solution in the buoyancy separation box 8 is discharged into the storage tank 20 through the guide pipe under the action of the pump for storage and recycling; it should be noted that there are gaps between the multiple complete, horizontal interception planes, and they are not completely sealed. The solution flows out through the gaps between the horizontal swing plates 19 of each layer. If the layers were completely sealed, each layer area would need to be equipped with The guide pipe connected to the liquid storage tank 20 is used for pumping out water. After the drainage is completed, the materials in each layer of the buoyancy sorting box 8 become material cakes placed on the plane of the swing plate 19. Finally, open the side inspection door of the buoyancy sorting box 8 (the inspection door needs to be sealed with the buoyancy sorting box 8, and the sealing structure adopts existing technology, which will not be described in detail here). Just like taking things from a multi-layer shelf, you can easily and clearly take out the various types of rubber waste that have been completely separated by density from their respective planes of the swing plate 19, and complete the final high-purity classification and collection.

[0071] This invention also discloses a method for recycling and processing solid waste from the production of anti-impact safety shoes. The method involves using the aforementioned equipment for recycling and processing solid waste from the production of anti-impact safety shoes, and includes the following steps:

[0072] S1: Pour the solution with adjusted density into the buoyancy separation box 8, check whether each mechanism is normal, and then start the drive motor 9 and the fan 142;

[0073] S2: The waste material from the production of anti-smashing safety shoes is put into the crushing box 2, and the two relatively rotating crushing rollers 201 crush the waste material into small pieces;

[0074] S3: The crushed waste enters the gold removal box 3 through the feeding hopper 4. The rotating gold removal part 11 adsorbs metal below the feeding port of the gold removal box 3. When it rotates to the top of the metal box 5, it automatically demagnetizes and releases the metal, thus completing the automatic and pure recovery of the metal.

[0075] S4: Non-metallic materials fall into the air separator 6, and the oscillating air outlet blows lightweight fabric and leather waste into the lightweight material box 7. The oscillation and concentrated spray of the air force ensure that there are no dead corners in the separation.

[0076] S5: The remaining materials enter the buoyancy sorting box 8. During the feeding process, the electric push rod 194 is activated to reciprocate and extend, so that the multi-layer swing plate 19 swings slowly to prevent heavy materials from pressing on light materials.

[0077] After stopping the feeding, allow the material to fully separate into layers according to density in the static solution. At this point, the electric push rod 194 stops working.

[0078] S6: After the settling is complete, control the electric push rod 194 to extend, so that all the swing plates 19 rotate to the horizontal position, forming a multi-layer complete flat tray to receive the materials of each layer.

[0079] The solution in the buoyancy sorting box 8 is pumped back to the storage tank 20 through the guide pipe. The side door is opened, and the rubber waste of different densities that have been sorted are taken out from the swing plates 19 of each layer.

[0080] The accompanying drawings in this application are for illustrative purposes only.

In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0081] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
