Description

Technical Field

[0001] This invention belongs to the field of environmentally friendly and harmless waste treatment technology, specifically relating to an environmentally friendly and harmless treatment device and method for shoe waste. Background Technology

[0002] Shoe waste refers to various footwear products that have entered the waste stage due to damage, obsolescence, loss of use value, or consumer discarding. These include sneakers, leather shoes, sandals, slippers, etc. Due to the complexity of modern shoe manufacturing processes, shoes are usually made of a combination of multiple materials, making them difficult to effectively recycle or degrade after disposal, thus putting pressure on the environment and resource recycling.

[0003] Environmentally friendly and harmless treatment devices are specialized equipment designed for waste (such as household waste, medical waste, dead animals, industrial waste, etc.). Their core objective is to transform harmful substances into harmless or less harmful substances through physical, chemical, or biological technologies, while simultaneously achieving resource utilization. Based on the environmentally friendly and harmless treatment technology for shoe waste, it can be divided into physical treatment devices, chemical treatment devices, biological treatment devices, energy recovery devices, and upgraded recycling devices. Shoe waste contains some natural materials, mainly cotton, leather, and bio-based plastics, which can be decomposed into organic fertilizer after microbial composting.

[0004] Publication number "CN111792954A" describes "an aerobic composting fermentation device for biological organic fertilizer, including a fermentation box, a driving mechanism provided on the outer wall of the front part of the fermentation box, a turning mechanism provided inside the fermentation box, the turning mechanism including an installation plate slidably connected to the driving mechanism, a first turning plate symmetrically distributed fixedly connected to the bottom of the installation plate, the first turning plate including an array of first turning teeth, and a first trapezoidal groove symmetrically distributed on the front and rear side walls of the installation plate, the top of the first trapezoidal groove being fixedly connected to a first gas spring; the present invention, through the setting of the turning mechanism, enables the fermentation agent to be mixed with the compost during the input process, avoiding the long mixing process required after concentrated input and stirring, thus improving the fermentation efficiency."

[0005] The aforementioned patent, through the setting of a turning mechanism, enables the fermentation agent to be mixed with the compost during the input process, avoiding the long mixing process required after concentrated input and stirring, thus improving fermentation efficiency. However, when shoe waste is mainly composed of natural materials such as cotton, leather, and bio-based plastics, it is necessary to ensure that the straw and microorganisms are fully in contact with and mixed with the broken cotton, leather, and bio-based plastics to form a compost. When the compost is harmlessly composted in the composting trough, the compost at the bottom of the trough is not easily turned to the surface to fully contact the air, resulting in a decrease in the decomposition efficiency of the aerobic bacteria in the bottom compost. Consequently, the composting efficiency in the composting trough is reduced when the environmentally friendly and harmless treatment method for shoe waste is actually applied. Therefore, we propose an environmentally friendly and harmless treatment device and method for shoe waste. Summary of the Invention

[0006] The purpose of this invention is to provide an environmentally friendly and harmless treatment device and method for shoe waste. The aim is to solve the problem by changing the mechanical structure of the turning mechanism, allowing the spiral turning blades to aggregate and turn the material in the composting trough, fully turning the material so that straw and microorganisms are fully mixed with crushed cotton, leather, and bio-based plastics. This process also turns the bottom material in the composting trough to the surface, ensuring sufficient air contact and improving the decomposition efficiency of aerobic bacteria in the bottom material.

[0019] An environmentally friendly and harmless treatment method for shoe waste, applied in the aforementioned environmentally friendly and harmless treatment device for shoe waste, the method comprising the following steps:

[0020] S1, Split:

[0021] The recycled used shoes are mechanically disassembled into biodegradable and non-biodegradable shoe waste, thus realizing the separation of used shoes;

[0022] S2, Crushed:

[0023] The non-biodegradable shoe waste is broken into uniformly sized pieces by a crusher, and metal fragments are magnetically screened out during the crushing process, thus achieving the crushing of biodegradable shoe waste.

[0024] S3, Pretreatment:

[0025] Crushed biodegradable shoe waste, straw, and microorganisms are evenly mixed in a mixer to form a composting material, which is then layered into the composting trough. After each layer of material is laid, the first electric push rod is activated. The output end of the first electric push rod retracts and pulls the push-pull rod, which in turn pulls the deflection rod. The deflection rod causes the hollow rod to rotate, lifting the two spiral turning blades out of the composting trough. Then, the drive motor is activated, and the output end of the drive motor drives the lead screw to rotate. The lead screw, through sliding cooperation with the hollow slider, pushes the hollow slider to move back and forth at the top of the composting trough. The hollow slider drives the nozzle and the pressurized storage tank to move back and forth. The pressurized storage tank injects high-pressure water into the nozzle through a hose. The nozzle sprays the high-pressure water into a uniform water mist, which is sprayed onto the surface of the composting material, providing sufficient moisture for the decomposition of shoe waste and achieving pretreatment before composting.

[0026] S4, Aggregation Turning:

[0027] After pretreatment, the compost in the composting trough undergoes its first microbial degradation. The output of the drive motor rotates the lead screw, which, through sliding contact with the hollow slider, pushes the slider to one side of the composting trough, causing the motor to shut down. Then, the output of the first electric push rod extends, pushing the push-pull rod closer to the deflector rod. The push-pull rod pushes the deflector rod, causing the hollow rod to flip within the receiving trough, bringing its other end into contact with the compost. The ratchet and two spiral turning blades are then inserted into the bottom of the compost pile. The drive motor is then powered on and started, its output driving the main... The driving wheel rotates, and the driving wheel drives the driven wheel to rotate via a belt. The driven wheel drives the first shaft to rotate, and the first shaft drives two spiral turning blades to rotate. Because the two spiral turning blades are symmetrically distributed, when the two spiral turning blades rotate, they push the pile of material to move closer together, pushing the material piled on the inside and outside of the composting trough towards the center. By squeezing and pushing the material between the two spiral turning blades, the material piled at the bottom of the composting trough is aggregated and pushed to the top, thereby causing the bottom pile of material to surge, aggregate, and be pushed out to the top surface of the pile, thus realizing the aggregation and turning of the bottom pile of material.

[0028] S5, Adjust the depth:

[0029] During the turning process of the bottom pile, the extension and retraction length of the first electric push rod controls the push-pull rod to move closer to or further away from the deflection rod, thereby controlling the turning angle of the hollow rod and the two spiral turning blades, so that the depth of the two spiral turning blades in the pile can be adjusted, thus realizing the adjustment of the turning depth.

[0030] S6, Reciprocating material turning:

[0031] While the material is being turned over, the motor drives the lead screw to rotate. The lead screw, through its sliding engagement with the hollow slider, pushes the hollow slider closer to the other side of the composting trough, causing the two spiral turning blades to move unidirectionally within the trough. This unidirectional turning of the material continues until the infrared positioner detects that the hollow slider is in contact with the other side of the composting trough. At this point, the first electric push rod is activated, its output retracting to lift the hollow rod and the two spiral turning blades onto the upper side of the hollow slider. Then, the motor is activated again, and the lead screw, through its sliding engagement with the hollow slider, pushes the slider back to its original position. When the infrared positioner detects that the space between the hollow slider and the inner wall of the other side of the composting trough is sufficient to accommodate the hollow rod and the two spiral turning blades during the slider's reset process, the second electric push rod is activated. Its output retracting pulls the pawl away from the pressurized storage box, engaging the pawl with the pressurized storage box. The motor is then powered on and started. The output of the motor drives the drive gear to rotate. The drive gear, through meshing with the driven gear, drives the second shaft to rotate. The second shaft drives the turntable and connecting rod assembly, the hollow rod, and the two spiral turning blades to rotate 180 degrees. After the hollow rod and the two spiral turning blades rotate 180 degrees, the output of the second electric push rod extends and pushes the pawl to engage with the ratchet, thereby limiting the deflection of the two spiral turning blades. Then, the output of the first electric push rod extends and pushes the push-pull rod close to the deflection rod, inserting the hollow rod and the two spiral turning blades back into the compost pile. The lead screw, through sliding engagement with the hollow slider, pushes the hollow slider to continue to reset at the top of the compost trough. At the same time, the two spiral turning blades rotate in the compost trough to turn the material at the other end of the pile. By reciprocating the movement of the two spiral turning blades, the material in the compost trough is turned back and forth.

[0032] S7, Maintain state:

[0033] During each round of turning, water mist is sprayed from the nozzles to replenish the moisture in the compost pile. After each round of turning, one end of the sunshade is pulled to cover the top of the composting trough, so that the composting trough is in a high-temperature state. This provides a high-temperature and high-moisture environment for the microorganisms in the compost pile, providing a suitable environment for microbial decomposition and maintaining the state of the microbial decomposition environment.

[0034] S8, Rapid Composting:

[0035] The material is piled up in an environmentally friendly and harmless treatment device for shoe waste. Through repeated turning and rapid decomposition in a high-temperature and high-moisture environment, the shoe waste is decomposed into green and harmless fertilizer, thus achieving rapid composting of shoe waste.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1. In this scheme, the compost material in the composting trough undergoes initial microbial degradation. The output of the driving motor rotates the lead screw, which, through sliding contact with the hollow slider, pushes the hollow slider to one side of the composting trough, causing the motor to shut down. Then, the output of the first electric push rod extends, pushing the push-pull rod closer to the deflection rod. The push-pull rod pushes the deflection rod, causing the hollow rod to flip within the receiving trough, bringing the other end of the hollow rod into contact with the compost material. The ratchet and two spiral turning blades are then inserted into the bottom of the compost pile. The drive motor is then powered on, and its output rotates the driving wheel. The driving wheel, via a belt, rotates the driven wheel, which in turn rotates the first shaft. The first shaft then rotates the two spiral turning blades. Because the blades are symmetrically distributed, the rotation of the two spiral turning blades pushes the material pile closer together, pushing the material piled on the inside and outside of the composting trough towards the center. By squeezing and pushing the material between the two spiral turning blades, the material at the bottom of the composting trough is aggregated and pushed to the top, causing the bottom material to surge, aggregate, and be pushed to the top surface of the pile. This process of aggregating and turning the bottom material ensures that the material is fully turned up and down, allowing the straw and microorganisms to fully contact and mix with the crushed cotton, leather, and bio-based plastics. Turning the bottom material in the composting trough to the surface allows it to fully contact the air, improving the decomposition efficiency of the aerobic bacteria in the bottom material. This enhances the composting efficiency of the composting trough in the practical application of the environmentally friendly and harmless treatment method for shoe waste.

[0038] 2. In this solution, when it is necessary to lock the deflection angle of the two spiral turning blades, the output end of the second electric push rod extends to push the pawl closer to the ratchet, so that the pawl engages with the ratchet, restricting the rotation of the second rotating shaft, thereby restricting the deflection of the two spiral turning blades. When it is necessary to deflect the two spiral turning blades, the output end of the second electric push rod retracts to pull the pawl away from the ratchet, so that the pawl is released from the engagement and lock with the ratchet. By controlling whether the pawl engages with the ratchet through the extension and retraction of the output end of the second electric push rod, the deflection angle of the two spiral turning blades can be effectively controlled, so that the two spiral turning blades can be accurately adjusted in direction, improving the turning accuracy of the shoe waste environmental protection and harmless treatment device for the pile.

[0039] 3. In this scheme, when it is necessary to rotate the two spiral turning blades at an angle, the first electric push rod is activated by power. The output end of the first electric push rod extends and pushes the push rod closer to the deflection rod. Then, the push rod pushes the deflection rod and the hollow rod to rotate clockwise in the receiving groove. The hollow rod presses the two spiral turning blades down to the depth of the pile. The output end of the first electric push rod retracts and pulls the push rod away from the deflection rod. The push rod pulls the deflection rod and the hollow rod to rotate counterclockwise in the receiving groove. Then, the hollow rod lifts the two spiral turning blades out of the pile. By controlling the extension and retraction length of the output end of the first electric push rod, the depth of the two spiral turning blades in the pile is controlled. This achieves the control of the turning depth of the pile in the environmentally friendly and harmless treatment device for shoe waste, adapting to the pile depth requirements of different shoe materials, controlling the oxygen content requirements of different shoe materials, and improving the composting applicability of the environmentally friendly and harmless treatment device for shoe waste of different materials.

[0040] 4. In this solution, when the two spiral turning blades reciprocate, the drive motor is started by powering on. The output end of the drive motor drives the lead screw to rotate. The lead screw, through sliding cooperation with the hollow slider, pushes the hollow slider to reciprocate within the two slide rails. This, in turn, drives the drive assembly, connecting rod assembly, rotating assembly, limiting assembly, and the two spiral turning blades to reciprocate at the top of the composting trough. This allows the two spiral turning blades to reciprocate within the composting trough, facilitating the reciprocating turning of the material in the composting trough and improving the turning efficiency of the material in the composting trough. Consequently, this improves the composting efficiency of the shoe waste environmental protection and harmless treatment device for cotton, leather, and bio-based plastics.

[0041] 5. In this solution, when the two spiral turning blades are deflected 180 degrees, the connecting rod assembly lifts the two spiral turning blades, the limit assembly releases the rotation lock on the second rotating shaft, and the power is turned on to start the rotating motor. The output end of the rotating motor drives the drive gear to rotate. The drive gear drives the driven gear to rotate through meshing with the driven gear. The driven gear drives the second rotating shaft to rotate. The second rotating shaft drives the turntable to rotate. The turntable then drives the drive assembly, connecting rod assembly, and two spiral turning blades to rotate 180 degrees as a whole. This facilitates the reciprocating movement of the two spiral turning blades and allows for the reversing of their direction, ensuring that the two spiral turning blades turn the material in the composting trough without dead angles and preventing the material at the bottom of the composting trough from being overlooked.

[0042] 6. In this solution, the infrared locator detects the position of the hollow slider at the top of the composting trough in real time by emitting infrared laser. The built-in program of the infrared locator sets the limit range of the hollow slider's reciprocating movement at the top of the composting trough. When the hollow slider moves to the limit value of unidirectional movement, it triggers the drive motor to shut down, drives the motor output to flip, and the output of the first electric push rod to extend and retract. This provides the trigger conditions for the movement program of the two spiral turning blades, making the shoe waste environmental protection and harmless treatment device have an automated function, which facilitates the daily use and maintenance of the shoe waste environmental protection and harmless treatment device.

All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0055] Example 1

[0056] Please see Figure 1 - Figure 9 This embodiment provides an environmentally friendly and harmless treatment device for shoe waste, which includes:

[0057] Compost trough 1;

[0058] Two spiral turning blades 3 are provided, positioned between the inner walls of the composting trough 1; and

[0059] The material turning mechanism is located between the inner walls of the composting trough 1 and is connected to two spiral turning blades 3 for moving the two spiral turning blades 3.

[0060] In this invention, the composting trough 1 is used to support and fix the sunshade 2 and two slide rails 24. The two spiral turning blades 3 turn the material in the composting trough 1 by rotating. The turning mechanism is connected to the two spiral turning blades 3 and is used to move the two spiral turning blades 3.

[0061] In a preferred embodiment, the turning mechanism includes a rotating component, a limiting component, a pushing component, a connecting rod component, a positioning component, and a driving component. The driving component is disposed between the inner walls of the composting tank 1 and is connected to the two spiral turning blades 3.

[0063] In a preferred embodiment, the pushing assembly includes a hollow slider 22, a slide rail 24, a lead screw 25, a pushing motor 26, and a guide rod 27. Two slide rails 24 are provided, and the two slide rails 24 are fixedly and parallel to the top of the composting tank 1. The lead screw 25 is rotatably connected between the inner walls of one slide rail 24, and one end of the lead screw 25 extends to the side end of the slide rail 24. The pushing motor 26 is fixedly connected to the top of the composting tank 1, and the output end of the pushing motor 26 is fixedly connected to the extension end of the pushing motor 26.

The hollow slider 22 is sleeved on the circumferential surface of the lead screw 25 and the guide rod 27, and the hollow slider 22 is located between the two slide rails 24.

[0064] In this invention, two slide rails 24 are used to accommodate guide rods 27 and lead screws 25. The lead screw 25, through sliding engagement with a hollow slider 22, pushes the hollow slider 22 to reciprocate at the top of the composting trough 1. A drive motor 26 provides power to rotate the lead screw 25, thereby providing power for the reciprocating movement of the two spiral turning blades 3. The guide rod 27, through sliding engagement with the hollow slider 22, assists in guiding the movement of the hollow slider 22. The hollow slider 22 accommodates rotating and limiting components. When the two spiral turning blades 3 reciprocate, the drive motor 26 is energized and activated. The output of the drive motor 26... The end drives the lead screw 25 to rotate. The lead screw 25 pushes the hollow slider 22 to reciprocate within the two slide rails 24 through sliding cooperation with the hollow slider 22. This, in turn, drives the drive assembly, connecting rod assembly, rotating assembly, limiting assembly, and two spiral turning blades 3 to reciprocate at the top of the composting tank 1. This allows the two spiral turning blades 3 to reciprocate within the composting tank 1, facilitating the reciprocating turning of the material in the composting tank 1 and improving the turning efficiency of the material in the composting tank 1. This, in turn, improves the composting efficiency of cotton, leather, and bio-based plastics in the environmentally friendly and harmless treatment device for shoe waste.

[0065] In a preferred embodiment, the rotating assembly includes a turntable 11, a receiving groove 12, a bearing 15, a second rotating shaft 16, a driven gear 17, a driving gear 18, a rotating motor 19, and a rotating hole 23. The rotating hole 23 is formed through the top of the hollow slider 22 and communicates with the inner wall of the hollow slider 22. The second rotating shaft 16 is rotatably connected between the inner circumferential walls of the hollow slider 22, and the driven gear 17 is fixedly connected to the circumferential surface of the second rotating shaft 16. The driven gear 17 is located on the hollow slider 22. Between the inner walls, a rotating motor 19 is fixedly connected to the bottom of the hollow slider 22, and the output end of the rotating motor 19 extends to the inner walls of the hollow slider 22. A drive gear 18 is fixedly connected to the circumferential surface of the output end of the rotating motor 19, and the drive gear 18 meshes with the driven gear 17. A turntable 11 is fixedly connected to the top of the second rotating shaft 16, and a receiving groove 12 is provided on the top of the turntable 11. A bearing 15 is installed at the top center of the hollow slider 22, and the bearing 15 is connected to the turntable 11.

[0066] In this invention, the rotating hole 23 is used to accommodate the second rotating shaft 16, which drives the turntable 11 to rotate. The driven gear 17 drives the second rotating shaft 16 to rotate. The rotating motor 19 rotates the driving gear 18. The rotating motor 19 is a stepper motor used to control the rotation angle of the two spiral turning blades 3. At the same time, the rotation program built into the rotating motor 19 detects the rotation angle at the output end and triggers the extension and retraction of the output end of the second electric push rod 21. The driving gear 18 drives the driven gear 17 to rotate through meshing with the driven gear 17. The turntable 11 supports the first electric push rod 14 and the hollow rod 4. The bearing 15 assists in supporting the turntable 11. When the two spiral turning blades 3 are deflected 180 degrees, the continuous... The rod assembly lifts the two spiral turning blades 3, the limit assembly releases the rotation lock on the second rotating shaft 16, and the power is turned on to start the rotating motor 19. The output end of the rotating motor 19 drives the drive gear 18 to rotate. The drive gear 18 drives the driven gear 17 to rotate through meshing with the driven gear 17. The driven gear 17 drives the second rotating shaft 16 to rotate. The second rotating shaft 16 drives the turntable 11 to rotate. The turntable 11 then drives the drive assembly, the connecting rod assembly and the two spiral turning blades 3 to rotate 180 degrees as a whole. This allows the two spiral turning blades 3 to change direction when they move back and forth, so that the two spiral turning blades 3 can turn the material in the composting tank 1 without dead corners, and avoid the material at the bottom of the composting tank 1 being ignored.

[0067] In a preferred embodiment, the limiting component includes a pawl 20, a second electric push rod 21, and a ratchet 31. The ratchet 31 is fixedly connected to the circumferential surface of the second rotating shaft 16. The pawl 20 is rotatably connected to the inner wall of the hollow slider 22, and the pawl 20 is engaged with the ratchet 31. The second electric push rod 21 is fixedly connected to the inner wall of the hollow slider 22, and the output end of the second electric push rod 21 is rotatably connected to the pawl 20.

[0068] In this invention, the ratchet 31 rotates synchronously with the second rotating shaft 16. The pawl 20 locks the rotation of the second rotating shaft 16 by engaging with the ratchet 31. The second electric push rod 21 pushes the pawl 20 closer to or away from the ratchet 31, thereby controlling whether the pawl 20 engages with the ratchet 31. When it is necessary to deflect and lock the two spiral turning blades 3, the output end of the second electric push rod 21 extends and pushes the pawl 20 closer to the ratchet 31, so that the pawl 20 engages with the ratchet 31, restricting the rotation of the second rotating shaft 16, thereby achieving... The deflection of the two spiral turning blades 3 is restricted. When it is necessary to deflect the two spiral turning blades 3, the output end of the second electric push rod 21 retracts and pulls the pawl 20 away from the ratchet 31, so that the pawl 20 is released from the lock of the ratchet 31. The extension and retraction of the output end of the second electric push rod 21 controls whether the pawl 20 is locked with the ratchet 31, effectively controlling the deflection angle of the two spiral turning blades 3, so that the two spiral turning blades 3 can accurately change direction, improving the turning accuracy of the shoe waste environmental protection and harmless treatment device for the stacked material.

[0069] In a preferred embodiment, the drive assembly includes a drive motor 5, a hollow rod 4, a driving wheel 6, a driven wheel 7, a first rotating shaft 8, and a belt 9. The hollow rod 4 is disposed between the inner walls of the composting trough 1, and one end of the hollow rod 4 is rotatably connected to the inner wall of the receiving trough 12. The first rotating shaft 8 is rotatably connected to the inner wall of the hollow rod 4, and both ends of the first rotating shaft 8 extend to the two side ends of the hollow rod 4. Both ends of the first rotating shaft 8 are fixedly connected to two spiral turning blades 3. Wheel 7 is fixedly connected to the circumferential surface of the first rotating shaft 8, and the driven wheel 7 is located between the inner walls of the hollow rod 4. The drive motor 5 is fixedly connected to the side end of the hollow rod 4, and the output end of the drive motor 5 extends to the inner walls of the hollow rod 4. The driving wheel 6 is fixedly connected to the circumferential surface of the output end of the drive motor 5, and the driving wheel 6 is located between the inner walls of the hollow rod 4. The belt 9 is sleeved between the inner walls of the driving wheel 6 and the driven wheel 7, and the belt 9 is located between the inner walls of the hollow rod 4.

[0070] In this invention, the hollow rod 4 houses the driving wheel 6, the driven wheel 7, the first shaft 8, and the belt 9. The hollow rod 4 also supports and fixes the drive motor 5 and the deflection rod 10. The first shaft 8 drives the two spiral turning blades 3 to rotate synchronously. The driven wheel 7 drives the first shaft 8 to rotate. The drive motor 5 drives the driving wheel 6 to rotate, and the driving wheel 6 drives the belt 9 to rotate, which in turn synchronously pulls the driven wheel 7 to rotate. The belt 9 is used for torque transmission between the driving wheel 6 and the driven wheel 7. When the two spiral turning blades 3 rotate, the drive motor 5 is energized and started. The output of the drive motor 5 drives the driving wheel 6 to rotate, and the driving wheel 6 synchronously drives the driven wheel 7 to rotate via the belt 9. The driven wheel 7 drives the first shaft 8 to rotate, and the first shaft 8 drives the two spiral turning blades 3 to rotate, thus providing power for the rotation of the two spiral turning blades 3.

[0071] In a preferred embodiment, the linkage assembly includes a deflection rod 10, a push-pull rod 13, and a first electric push rod 14. The deflection rod 10 is fixedly connected to one end of the hollow rod 4. The push-pull rod 13 slides between the inner walls of the receiving groove 12, and the push-pull rod 13 and the deflection rod 10 are rotatably connected by a hinge. The first electric push rod 14 is fixedly connected to the side end of the turntable 11. The output end of the first electric push rod 14 extends between the inner walls of the receiving groove 12, and the output end of the first electric push rod 14 is fixedly connected to the push-pull rod 13.

[0072] In this invention, the deflecting rod 10 is used to drive the hollow rod 4 to rotate, and the push-pull rod 13 is used to push and pull the deflecting rod 10 to deflect it. The first electric push rod 14 extends and retracts the push-pull rod 13 through its output end. When it is necessary to rotate the two spiral turning blades 3 at an angle, the first electric push rod 14 is started by powering on. The output end of the first electric push rod 14 extends and pushes the push-pull rod 13 closer to the deflecting rod 10. Then, the push-pull rod 13 pushes the deflecting rod 10 and the hollow rod 4 to rotate clockwise in the receiving groove 12. The hollow rod 4 presses the two spiral turning blades 3 down to the depth of the material pile. The output end of rod 14 retracts, pulling push rod 13 away from deflection rod 10. Push rod 13 pulls deflection rod 10 and hollow rod 4 to rotate counterclockwise within receiving groove 12. Then, hollow rod 4 lifts two spiral turning blades 3 out of the pile. By controlling the extension and retraction length of the output end of the first electric push rod 14, the depth of the two spiral turning blades 3 in the pile is controlled, so as to achieve the control of the turning depth of the pile by the environmentally friendly and harmless treatment device for shoe waste, adapt to the pile depth requirements of different shoe materials, achieve the control of the oxygen content requirements of different shoe materials, and improve the composting range of different shoe waste materials by the environmentally friendly and harmless treatment device for shoe waste.

[0073] The positioning component includes an infrared locator 28, which is fixedly connected to the bottom of the hollow slider 22 and located between the inner walls of the composting tank 1. The infrared locator is a component that uses infrared light for target detection and position tracking. Its core components include an infrared transmitter, a receiver, and a signal processing unit. The infrared locator is a mature component in existing technology, and its specific composition and working principle will not be further explained here. Those skilled in the art can select the appropriate type and specific model according to actual needs.

[0074] In this invention, the infrared locator 28 detects the position of the hollow slider 22 at the top of the composting tank 1 in real time by emitting infrared laser. The infrared locator 28 has a built-in program that sets the limit range of the hollow slider 22's reciprocating movement at the top of the composting tank 1. When the hollow slider 22 moves to the limit value of unidirectional movement, it triggers the drive motor 5 to shut down, drives the output end of the motor 26 to flip, and the output end of the first electric push rod 14 to extend and retract. This provides the trigger conditions for the movement program of the two spiral turning blades 3, so that the shoe waste environmental protection and harmless treatment device has an automated function, which facilitates the daily use and maintenance of the shoe waste environmental protection and harmless treatment device.

[0075] The bottom of the hollow slider 22 is fixedly connected to a nozzle 29 and a pressurized storage box 30. The pressurized storage box 30 and the nozzle 29 are connected by a hose. The bottom of the hollow rod 4 is fixedly connected to a guide plate 32. A sunshade 2 is installed on the top of the composting trough 1.

[0076] In this invention, the nozzle 29 is used to spray water mist to provide moisture to the compost pile. The pressurized storage tank 30 is connected to an external water source and is used to pump pressurized water into the nozzle 29. The guide plate 32 is used to guide the compost pile and guide it to move upwards. At the same time, when the two spiral turning blades 3 are inserted into the compost pile, the guide plate 32 diverts the compost pile, reducing the difficulty of inserting the hollow rod 4 and the two spiral turning blades 3 into the compost pile. The sunshade 2 is used to shade and seal the compost pile in the composting tank 1 to prevent the microorganisms in the compost pile in the composting tank 1 from being deactivated by direct sunlight and reducing the composting efficiency.

[0077] Example 2

[0078] This embodiment 2 provides an environmentally friendly and harmless treatment method for shoe waste, which is applied to the environmentally friendly and harmless treatment method for shoe waste described in embodiment 1 above. The method includes the following steps:

[0079] S1, Split:

[0080] The recycled used shoes are mechanically disassembled into biodegradable and non-biodegradable shoe waste, thus realizing the separation of used shoes;

[0081] S2, Crushed:

[0082] The non-biodegradable shoe waste is broken into uniformly sized pieces by a crusher, and metal fragments are magnetically screened out during the crushing process, thus achieving the crushing of biodegradable shoe waste.

[0083] S3, Pretreatment:

[0084] Crushed biodegradable shoe waste, straw, and microorganisms are evenly mixed in a mixer to form compost, which is then layered into composting trough 1. After each layer is laid, the first electric push rod 14 is activated. The output end of the first electric push rod 14 retracts, pulling the push-pull rod 13. The push-pull rod 13 pulls the deflection rod 10, which in turn causes the hollow rod 4 to rotate, lifting the two spiral turning blades 3 out of the composting trough 1. Then, the drive motor 26 is activated, driving the drive motor 2... The output end of 6 drives the lead screw 25 to rotate. The lead screw 25 pushes the hollow slider 22 to reciprocate at the top of the composting tank 1 through sliding cooperation with the hollow slider 22. The hollow slider 22 drives the nozzle 29 and the pressurized storage box 30 to reciprocate. The pressurized storage box 30 injects high-pressure water into the nozzle 29 through the hose. The nozzle 29 sprays the high-pressure water into a uniform water mist and sprays it onto the surface of the compost pile to provide sufficient moisture for the decomposition of shoe waste and achieve pretreatment before composting.

[0085] S4, Aggregation Turning:

[0086] After pretreatment, the compost in the composting tank 1 undergoes initial microbial degradation. The output of the drive motor 26 rotates the lead screw 25. The lead screw 25, through sliding engagement with the hollow slider 22, pushes the hollow slider 22 to one side of the composting tank 1. The drive motor 26 is then de-energized and stopped. Then, the output of the first electric push rod 14 extends, pushing the push-pull rod 13 closer to the deflection rod 10. The push-pull rod 13 pushes the deflection rod 10, causing the hollow rod 4 to flip within the receiving trough 12, so that the other end of the hollow rod 4 contacts the compost. The ratchet 31 and two spiral turning blades 3 are inserted into the bottom of the compost. The drive motor 5 is then energized and started. The output of the motor 5 drives the active rotating wheel 6 to rotate. The active rotating wheel 6 drives the driven rotating wheel 7 to rotate via the belt 9. The driven rotating wheel 7 drives the first rotating shaft 8 to rotate. The first rotating shaft 8 drives the two spiral turning blades 3 to rotate. Since the two spiral turning blades 3 are symmetrically distributed, when the two spiral turning blades 3 rotate, they push the pile of material to move closer together, pushing the pile of material accumulated on the inside and outside of the composting tank 1 towards the center. By squeezing and pushing between the two spiral turning blades 3, the bottom pile of material in the composting tank 1 is aggregated and pushed to the top, and then the bottom pile of material is turned over and pushed to the top surface of the pile, thus realizing the aggregation and turning of the bottom pile of material.

[0087] S5, Adjust the depth:

[0088] During the turning process of the bottom pile, the extension and retraction length of the first electric push rod 14 controls the push-pull rod 13 to approach or move away from the deflection rod 10, thereby controlling the turning angle of the hollow rod 4 and the two spiral turning blades 3, so that the depth of the two spiral turning blades 3 in the pile can be adjusted, thereby realizing the adjustment of the turning depth.

[0089] S6, Reciprocating material turning:

[0090] While the material is being turned over, the motor 26 drives the lead screw 25 to rotate. The lead screw 25, through its sliding engagement with the hollow slider 22, pushes the hollow slider 22 closer to the other side of the composting trough 1, causing the two spiral turning blades 3 to move unidirectionally within the composting trough 1. This achieves unidirectional turning of the material within the composting trough 1 until the infrared positioner 28 detects that the hollow slider 22 is in contact with the other side of the composting trough 1. At this point, the first electric push rod 14 is activated, and the output end of the first electric push rod 14 retracts, engaging the hollow rod 4 and the two spiral turning blades. The rotating material-turning blade 3 is raised to the upper side of the hollow slider 22, and then the drive motor 26 is started. The lead screw 25 pushes the hollow slider 22 to reset through sliding cooperation with the hollow slider 22. When the infrared positioner 28 detects that the space between the hollow slider 22 and the inner wall of the other side of the composting tank 1 can accommodate the hollow rod 4 and the two spiral material-turning blades 3 during the reset process, the second electric push rod 21 is started. The output end of the second electric push rod 21 retracts and pulls the pawl 20 away from the pressurized storage box 30, and the pawl 20 contacts the pressurized storage box. The pawl 30 engages, and then the power is turned on to start the rotating motor 19. The output end of the rotating motor 19 drives the drive gear 18 to rotate. The drive gear 18, through meshing with the driven gear 17, drives the second rotating shaft 16 to rotate. The second rotating shaft 16 drives the turntable 11, the connecting rod assembly, the hollow rod 4, and the two spiral turning blades 3 to rotate 180 degrees. After the hollow rod 4 and the two spiral turning blades 31 rotate 180 degrees, the output end of the second electric push rod 21 extends to push the pawl 20 to engage with the ratchet 31, thereby limiting the two... The spiral turning blades 3 deflect, and then the output end of the first electric push rod 14 extends to push the push-pull rod 13 close to the deflection rod 10, so that the hollow rod 4 and the two spiral turning blades 3 are inserted into the pile again. The screw 25 pushes the hollow slider 22 to continue to reset at the top of the composting tank 1 through sliding cooperation with the hollow slider 22. At the same time, the two spiral turning blades 3 turn the pile at the other end by rotating in the composting tank 1. By moving the two spiral turning blades 3 back and forth, the pile in the composting tank 1 is turned back and forth.

[0091] S7, Maintain state:

[0092] During each round of turning, the nozzle 29 sprays water mist to replenish the moisture of the compost pile. After each round of turning, one end of the sunshade 2 is pulled to cover the top of the composting trough 1, so that the composting trough 1 is in a high-temperature state, providing a high-temperature and high-moisture environment for the microorganisms in the composting trough 1, providing a suitable environment for microbial decomposition, and maintaining the state of the microbial decomposition environment.

[0093] S8, Rapid Composting:

[0094] The material is piled up in an environmentally friendly and harmless treatment device for shoe waste. Through repeated turning and rapid decomposition in a high-temperature and high-moisture environment, the shoe waste is decomposed into green and harmless fertilizer, thus achieving rapid composting of shoe waste.

[0095] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.

S3, Pretreatment: The crushed biodegradable shoe waste, straw, and microorganisms are evenly mixed in a mixer to form compost, which is then layered into the composting trough (1). After each layer of compost is laid in the composting trough (1), the first electric push rod (14) is activated. The output end of the first electric push rod (14) retracts and pulls the push-pull rod (13). The push-pull rod (13) pulls the deflection rod (10), which drives the hollow rod (4) to rotate, lifting the two spiral turning blades (3) out of the composting trough (1). Then, the drive motor (26) is activated. The output end of 26) drives the lead screw (25) to rotate. The lead screw (25) pushes the hollow slider (22) to reciprocate at the top of the composting tank (1) through sliding cooperation with the hollow slider (22). The hollow slider (22) drives the nozzle (29) and the pressurized storage box (30) to reciprocate. The pressurized storage box (30) injects high-pressure water into the nozzle (29) through the hose.

S4, Aggregation Turning: After pretreatment, the compost in the composting tank (1) undergoes microbial degradation for the first time. The output end of the drive motor (26) drives the lead screw (25) to rotate. The lead screw (25) pushes the hollow slider (22) to one side of the composting tank (1) through sliding cooperation with the hollow slider (22). The drive motor (26) is powered off and stopped. Then, the output end of the first electric push rod (14) extends and pushes the push-pull rod (13) close to the deflection rod (10). The push-pull rod (13) pushes the deflection rod (10). The deflection rod (10) drives the hollow rod (4) to flip in the receiving tank (12), so that the other end of the hollow rod (4) contacts the compost. The ratchet (31) and the two spiral turning blades (3) are inserted into the bottom of the compost. The drive motor is powered on and started.

The driven rotating wheel (7) drives the first rotating shaft (8) to rotate. The first rotating shaft (8) drives the two spiral turning blades (3) to rotate. Since the two spiral turning blades (3) are symmetrically distributed, when the two spiral turning blades (3) rotate, they push the pile of material to move closer together, pushing the pile of material piled on the inside and outside of the composting tank (1) towards the center. By squeezing and pushing the material between the two spiral turning blades (3), the material piled at the bottom of the composting tank (1) is aggregated and pushed to the top, and then the material piled at the bottom is turned over and aggregated and pushed out to the top surface of the pile, thus realizing the aggregation and turning of the material piled at the bottom. S5, Adjust the depth: During the turning process of the bottom pile, the extension and retraction length of the first electric push rod (14) is used to control the push-pull rod (13) to move closer to or further away from the deflection rod (10), thereby controlling the turning angle of the hollow rod (4) and the two spiral turning blades (3), so that the depth of the two spiral turning blades (3) in the pile can be adjusted, thereby realizing the adjustment of the turning depth. S6, Reciprocating material turning: While the material is being turned over, the motor (26) drives the lead screw (25) to rotate. The lead screw (25) pushes the hollow slider (22) closer to the other side of the composting tank (1) through sliding cooperation with the hollow slider (22), so that the two spiral turning blades (3) move unidirectionally in the composting tank (1), realizing unidirectional turning of the material in the composting tank (1) until the infrared locator (28) detects that the hollow slider (22) is in contact with the other side of the composting tank (1). Then, the first electric push rod (14) is started, and the output end of the first electric push rod (14) retracts to the hollow rod (4) and the two spiral blades. The material-turning blade (3) is raised to the upper side of the hollow slider (22), and then the drive motor (26) is started by power. The lead screw (25) pushes the hollow slider (22) to reset and move through sliding cooperation with the hollow slider (22). When the infrared positioner (28) detects that the space between the hollow slider (22) and the inner wall of the other side of the composting tank (1) can accommodate the hollow rod (4) and the two spiral material-turning blades (3) during the reset process, the second electric push rod (21) is started by power. The output end of the second electric push rod (21) retracts and pulls the pawl (20) away from the pressurized storage tank (30) and contacts the pressurized storage tank. The box (30) is engaged, and then the power is turned on to start the rotating motor (19). The output end of the rotating motor (19) drives the drive gear (18) to rotate. The drive gear (18) drives the second rotating shaft (16) to rotate through meshing with the driven gear (17). The second rotating shaft (16) drives the turntable (11), the connecting rod assembly, the hollow rod (4), and the two spiral turning blades (3) to rotate 180 degrees.

By moving the two spiral turning blades (3) back and forth, the pile in the composting tank (1) is turned back and forth. S7, Maintain state: During each round of turning, the nozzle (29) sprays water mist to replenish the moisture of the compost pile. After each round of turning, one end of the shade shed (2) is pulled to cover the top of the composting trough (1), so that the composting trough (1) is in a high temperature state, providing a high temperature and high moisture environment for the microorganisms in the composting trough (1), providing a suitable microbial decomposition environment, and maintaining the microbial decomposition environment. S8, Rapid Composting: The material is piled up in an environmentally friendly and harmless treatment device for shoe waste. Through repeated turning and rapid decomposition in a high-temperature and high-moisture environment, the shoe waste is decomposed into green and harmless fertilizer, thus achieving rapid composting of shoe waste.
