Description

Technical Field

[0001] This invention belongs to the field of plastic recycling technology, specifically a silent shredder for recycling waste plastic pipes. Background Technology

[0002] With the continuous development of the waste plastic recycling industry, the demand for recycling silent waste plastic pipes is increasing due to their ability to reduce fluid transport noise in early applications.

[0003] To achieve quiet operation, silent waste plastic pipes undergo specialized material modification, typically incorporating toughening agents and elastomers to enhance flexibility and impact resistance. This directly results in a softening temperature significantly lower than that of ordinary plastic pipes. During existing shredder operations, the shredding teeth must maintain continuous contact and compression with the pipe surface to complete the tearing action. Due to the pipe's high flexibility, it is difficult to cut it instantly, significantly extending the contact time between the shredding teeth and the pipe. This increases the frictional stroke and intensifies the frictional heat generation effect. Simultaneously, the connection points between the shredding teeth and the rotating parts of the equipment generate additional friction during operation, further leading to heat accumulation and a rapid rise in temperature on the surface of the shredding teeth and the internal contact parts of the equipment. Furthermore, some silent pipes are designed with smooth inner or outer walls to reduce fluid impact noise. During shredding, the pipe easily slips on the surface of the shredding teeth, increasing the number of ineffective frictions between the shredding teeth and the pipe, and generating even more heat.

[0004] The accumulated heat directly causes localized softening of the silent plastic pipe. The softened plastic easily adheres to the surface of the crushing teeth. As the adhesive accumulates, the gaps between the teeth of the crushing teeth become blocked, significantly reducing its gripping ability on the pipe. This not only significantly reduces the shredding efficiency but may also cause jamming due to uneven force on the crushing teeth, ultimately leading to equipment shutdown. At the same time, the plastic adhering to the contact parts inside the equipment will be heated as the equipment continues to operate, which may cause localized degradation, producing impurities that mix into the recycled plastic and affect the purity of the recycled material.

[0005] Therefore, the present invention provides a silent shredder for recycling waste plastic pipes. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0010] The material guiding mechanism includes a material guiding frame and a filter layer. The filter layer is fixedly installed inside the material guiding frame and located directly above the storage box. The material guiding frame is fixedly installed on the bottom surface of the mounting frame.

[0011] The circulation mechanism is used to transport the spray liquid inside the storage tank to the inner cavity of the transmission cylinder and the nozzle;

[0012] The control mechanism includes an elastic plate and a hammer. The hammer is set inside the transmission cylinder via the elastic plate, and the movement of the hammer is controlled by hydraulic pressure within the transmission cylinder cavity.

[0013] The stirring mechanism is used to stir the spray liquid inside the storage tank.

[0014] Preferably, the circulation mechanism includes a control pump, an input pipe, an output pipe, and a transfer plate;

[0015] The control pump is fixedly installed on the outer wall of the mounting bracket, and the input end is located inside the storage tank. The adapter plate is rotatably installed inside the transmission cylinder through a sealed bearing. Both the input pipe and the output pipe are connected to the transmission cylinder through the adapter plate.

[0016] One end of the inlet pipe is connected to the output end of the control pump, and one end of the outlet pipe is connected to the nozzle.

[0017] Preferably, the disturbance mechanism includes a sliding frame, a mounting beam, a connecting frame, a cross plate, and a limiting plate;

[0018] The sliding frame is slidably installed inside the storage box, the mounting beam is fixedly installed on the side wall of the sliding frame, one end of the connecting frame is fixedly connected to the outer wall of the mounting beam, the side wall of the horizontal plate is rotatably connected to the connecting frame, and the limiting plate is fixedly installed on one side of the connecting frame.

[0019] Preferably, a control plug is slidably installed on the inner wall of the transmission cylinder, and the outer wall of the control plug is in a sealed fit with the inner wall of the transmission cylinder;

[0020] A connecting shaft is fixedly installed at one end of the control plug. A pressing inclined plate for pressing the hammer is fixedly installed on the radial outer wall of the connecting shaft. A guide frame is fixedly installed on the inner wall of the transmission cylinder. The connecting shaft passes through the guide frame, and its outer wall slides against the inner wall of the guide frame. A spiral groove is opened on the outer wall of the connecting shaft. A ball bearing that slides with the spiral groove is fixedly installed on the inner wall of the guide frame.

[0021] A drive motor is fixedly installed on the outer wall of the mounting frame. The drive motor is used to control the rotation of the transmission cylinder. A feed hopper is fixedly installed on the upper end face of the mounting frame.

[0022] Preferably, a support cylinder is rotatably mounted on the inner wall of the storage tank, and a filter cylinder is fixedly mounted on the outer wall of the support cylinder. A rigid tube is connected to the axial end of the support cylinder through a sealed bearing. The rigid tube passes through the storage tank and is connected to the input end of the control pump.

[0023] The inner wall of the storage box is detachably fitted with a collection box. The upper end of the collection box has an opening. A scraper is fixedly installed on the inner wall of the collection box. The other end of the scraper is attached to the outer wall of the filter cartridge. A baffle is fixedly installed on the outer wall of the rigid tube. The outer wall of the baffle is attached to the inner wall of the support cylinder and is directly opposite the upper opening of the collection box.

[0024] Preferably, a control motor is fixed to the outer wall of the storage box, the output shaft of the control motor extends to the inner wall of the storage box, and a top pressure cam is fixedly installed thereon;

[0025] A support plate is fixedly installed on the inner wall of the storage box. The sliding frame is elastically connected to the support plate. A contact block is fixedly installed at one end of the sliding frame. A top-pressure cam is used to impact the contact block.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention provides precise protection for the core characteristics of silent plastic pipes, namely low softening temperature and easy adhesion, by setting up a spray mechanism with nozzles and a storage tank, a circulation mechanism with a control pump and an internal channel of the transmission cylinder, and a control mechanism with a hammer, an elastic plate, and a top pressure inclined plate. The storage tank stores softened water, which is simultaneously delivered to the nozzles and the transmission cylinder by the control pump. The liquid sprayed from the nozzles can fill the gap between the crushing teeth and the pipe, buffer the impact and reduce noise, and directly absorb frictional heat. The liquid in the transmission cylinder is cooled from the root of the crushing teeth. The internal and external dual cooling structure completely avoids pipe softening caused by local overheating. At the same time, the top pressure inclined plate slides with the control plug to push the hammer. The hammer strikes the transmission cylinder with the elastic force of the elastic plate, causing the crushing teeth to vibrate. This not only shakes off the plastic fragments adhering to the tooth surface, but also helps to adjust the position of the pipe to be crushed to improve the gripping force. This effectively solves the problem of low shredding efficiency and jamming stoppage caused by adhesion in existing equipment. It ensures the stability of the shredding process while maintaining the physical properties and purity of the recycled pipe.

[0028] 2. This invention achieves clean circulation and efficient heat dissipation of the spray liquid by setting up a filter cylinder, scraper, and collection box in the storage tank, as well as a horizontal plate, sliding frame, and top pressure cam in the stirring mechanism. The top pressure cam rotates and strikes the contact block, driving the sliding frame to slide back and forth. The horizontal plate is limited to unidirectional deflection by the limiting plate. When pushing the liquid flow, it not only accelerates the heat dissipation of the spray liquid, but also guides the liquid to flow through the filter cylinder to remove impurities. The scraper adheres to the filter cylinder and scrapes off the impurities adsorbed on the surface in real time. The impurities fall into the detachable collection box for easy cleaning. The baffle plate can also prevent impurities from escaping from the collection box, ensuring that the spray liquid drawn by the control pump is always clean and avoiding impurities from wearing down parts or mixing with recycled materials and affecting purity. In addition, the spray liquid flows back to the storage tank for reuse through the filter layer of the guide frame, reducing resource waste, reducing equipment operating energy consumption and maintenance costs, and fully adapting to the long-term and efficient recycling needs of silent waste plastic pipes.

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0042] like Figures 1 to 10 As shown, the silent waste plastic pipe recycling shredder of the present invention includes a crushing section, a spraying mechanism, a circulation mechanism, a material guiding mechanism, a control mechanism, and a stirring mechanism.

[0043] The crushing section includes a mounting frame 1, a transmission cylinder 9, and crushing teeth 10. The transmission cylinder 9 is rotatably disposed inside the mounting frame 1. In this embodiment, there are two transmission cylinders 9. The radial outer walls of the two transmission cylinders 9 are provided with gears, and the two gears mesh with each other. Rotating one transmission cylinder 9 will drive the other transmission cylinder 9 to rotate synchronously.

[0044] The crushing tooth 10 is fixedly installed on the outer wall of the transmission cylinder 9. During operation, the plastic tube is put onto the crushing tooth 10, and the crushing tooth 10 tears the plastic tube. The shredded plastic tube is discharged from below.

[0045] The outer wall of the mounting frame 1 is fixedly equipped with a drive motor 6, which is used to control the rotation of the transmission cylinder 9. The output shaft of the drive motor 6 is connected to the axial end of one of the transmission cylinders 9 through a coupling, thereby controlling the rotation of the crushing teeth 10 to realize the shredding operation of the plastic tube. In order to facilitate the input of the plastic tube, a feed hopper 2 is fixedly installed on the upper end face of the mounting frame 1.

[0046] The spraying mechanism includes a storage tank 7 and nozzles 4. The nozzles 4 are fixedly installed on the outer wall of the feed hopper 2. The storage tank 7 is used to store the spraying liquid (in this embodiment, the spraying liquid is softened water). Multiple nozzles 4 are evenly arranged along the outer wall of the feed hopper 2. When the plastic tube is torn, the spraying liquid in the storage tank 7 is transported to the nozzles 4 and then discharged from the nozzles 4.

[0047] When the plastic pipe is broken, the spray liquid is sprayed out through the nozzle 4. On the one hand, the liquid can fill the gap between the crushing tooth 10 and the pipe, buffer the impact force between the two, and further reduce the extra noise of the pipe, which is designed to be quiet, during the crushing process, which meets the noise reduction requirements of its quietness attribute. On the other hand, the liquid can also absorb frictional heat, prevent the flexible material from softening and sticking due to high temperature, ensure the stability of the crushing process, and maintain the physical properties of the pipe after recycling.

[0048] The material guiding mechanism includes a material guiding frame 3 and a filter layer 5. The filter layer 5 is fixedly installed inside the material guiding frame 3 and located directly above the storage box 7. The material guiding frame 3 is fixedly installed on the bottom surface of the mounting frame 1. The material guiding frame 3 is inclined. The shredded material falls above the material guiding frame 3 and is separated and discharged by the filter layer 5. That is, the liquid seeps downward through the filter layer 5, and the solid is discharged through one end of the material guiding frame 3. After the sprayed liquid passes through the filter layer 5, it re-enters the inner cavity of the storage box 7 for reuse.

[0049] In this embodiment, the storage box 7 is made of aluminum alloy to facilitate heat dissipation and cooling of the recycled spray liquid.

[0050] The circulation mechanism is used to transport the spray liquid inside the storage tank 7 to the inner cavity of the transmission cylinder 9 and the nozzle 4, providing power for the spray liquid delivery. In the shredding operation of silent plastic pipes, when the crushing teeth 10 fixed to the outside of the transmission cylinder 9 are shredding, the spray liquid is sprayed out by controlling the nozzle 4 to cool the outside of the crushing teeth 10. At the same time, cold water flows inside the transmission cylinder 9 to cool the crushing teeth 10 from the root. This dual cooling setting can avoid local overheating of the crushing teeth 10 compared with external spraying alone. It can also more effectively prevent the pipe from softening and sticking due to high temperature of the tooth surface, reducing crushing jamming, and protect the key stress parts of the crushing teeth 10 from the inside of the transmission cylinder 9 to maintain its overall strength. It can extend the service life of the crushing teeth 10 more than external spraying alone, and accurately adapt to the crushing needs of silent plastic pipes.

[0051] The control mechanism includes an elastic plate 16 and a hammer 17. The hammer 17 is installed inside the transmission cylinder 9 via the elastic plate 16, and its movement is controlled by hydraulic pressure within the transmission cylinder 9. When the transmission cylinder 9 rotates, the hammer 17 is pulled away from the inner wall of the transmission cylinder 9 and then released, thereby striking the inner wall of the transmission cylinder 9. This causes the transmission cylinder 9 and the crushing teeth 10 to vibrate. On the one hand, this vibration helps to remove plastic debris adhering to the surface of the crushing teeth 10, which is characterized by the high flexibility and easy adhesion of silent plastic pipes, thus preventing the teeth from clogging and affecting the shredding efficiency. On the other hand, it can clean the plastic residue remaining on the inner wall of the transmission cylinder 9, preventing the accumulation of residue from increasing the rotational resistance of the transmission cylinder 9. At the same time, the slight vibration can also help adjust the position of the plastic pipe to be crushed in the crushing area, allowing the crushing teeth 10 to grip the pipe more accurately, further improving the shredding effect. This effectively compensates for the adhesion and jamming problems that easily occur when shredding by rotating the crushing teeth 10 alone, and is suitable for the recycling and processing needs of silent waste plastic pipes.

[0052] The stirring mechanism is used to stir the spray liquid inside the storage tank 7 to facilitate uniform heat dissipation after the spray liquid is recovered.

[0053] The circulation mechanism includes a control pump 8, an input pipe 13, an output pipe 14, and a transfer plate 12. The control pump 8 is a common water-air dual-purpose pump.

[0054] The control pump 8 is fixedly installed on the outer wall of the mounting bracket 1, and its input end is located inside the storage tank 7, so that the control pump 8 can draw liquid from the storage tank 7. It should be noted that the input end of the control pump 8 needs to be close to the liquid surface inside the storage tank 7. When the liquid inside the storage tank 7 is stirred, the liquid surface will fluctuate, which will cause the input end of the control pump 8 to alternately draw in liquid and gas, thus causing its output water pressure to be unstable.

[0055] The adapter plate 12 is rotatably mounted inside the transmission cylinder 9 via a sealed bearing. The input pipe 13 and the output pipe 14 are both connected to the transmission cylinder 9 via the adapter plate 12. The input pipe 13 and the output pipe 14 both pass through the adapter plate 12 and extend into the inner cavity of the transmission cylinder 9.

[0056] One end of the input pipe 13 is connected to the output end of the control pump 8, and one end of the output pipe 14 is connected to the nozzle 4. Thus, when the control pump 8 is working, the liquid in the storage tank 7 is transported to the inside of the transmission cylinder 9, and then discharged from the transmission cylinder 9 to the nozzle 4. After spraying, it flows back to the inner cavity of the storage tank 7.

[0057] The disturbance mechanism includes a sliding frame 29, a mounting beam 31, a connecting frame 35, a cross plate 30, and a limiting plate 15.

[0058] The sliding frame 29 is slidably installed inside the storage box 7, and the mounting beam 31 is fixedly installed on the side wall of the sliding frame 29. The sliding adjustment of the sliding frame 29 drives the mounting beam 31 to slide synchronously.

[0059] One end of the connecting frame 35 is fixedly connected to the outer wall of the mounting beam 31, and the side wall of the horizontal plate 30 is rotatably connected to the connecting frame 35. A torsion spring is provided at the connection position to keep the horizontal plate 30 in a vertical state at all times. The limiting plate 15 is fixedly installed on one side of the connecting frame 35. The deflection direction of the horizontal plate 30 can be limited by the setting of the limiting plate 15.

[0060] When the sliding frame 29 slides forward, the horizontal plate 30 is blocked by the limiting plate 15, remains vertical, and pushes the liquid in the storage tank 7. When the sliding frame 29 slides in the reverse direction, the horizontal plate 30 is deflected by the liquid resistance, reducing the thrust on the liquid. Thus, the liquid in the storage tank 7 can be stirred by the horizontal plate 30 through the reciprocating sliding of the sliding frame 29.

[0061] In a preferred embodiment of this invention, a control plug 20 is slidably installed on the inner wall of the transmission cylinder 9. The outer wall of the control plug 20 is sealed and fitted to the inner wall of the transmission cylinder 9. A spring is provided on one side of the control plug 20, and the other end of the spring is connected to the inner wall of the transmission cylinder 9. When the horizontal plate 30 agitates the liquid and causes water waves to be generated on the liquid surface, the input end of the control pump 8 alternately draws in liquid and gas, thereby causing fluctuations in its output water pressure, which is used to drive changes in the water pressure inside the transmission cylinder 9, thereby driving the control plug 20 to slide back and forth.

[0062] One end of the control plug 20 is rotatably mounted with a connecting shaft 22. During the sliding process of the control plug 20, the connecting shaft 22 is driven to slide synchronously. The radial outer wall of the connecting shaft 22 is fixedly mounted with a pressing inclined plate 18 for pressing the hammer 17. Rotating the connecting shaft 22 drives the pressing inclined plate 18 to rotate, and the inclined surface of the pressing inclined plate 18 pushes the hammer 17 to lift up until the pressing inclined plate 18 and the hammer 17 separate. At this time, the hammer 17 separates and is subjected to the elastic force of the elastic plate 16, which controls the hammer 17 to strike the inner wall of the transmission cylinder 9, thereby generating vibration.

[0063] A guide frame 19 is fixedly installed on the inner wall of the transmission cylinder 9. The connecting shaft 22 passes through the guide frame 19, and its outer wall slides against the inner wall of the guide frame 19, thereby improving the stability of the sliding of the connecting shaft 22.

[0064] The outer wall of the connecting shaft 22 is provided with a spiral groove 21, and the inner wall of the guide frame 19 is fixedly installed with a ball that slides in cooperation with the spiral groove 21. When the control plug 20 drives the connecting shaft 22 to slide back and forth, the ball and the spiral groove 21 cooperate to control the connecting shaft 22 to deflect back and forth, which drives the top pressure plate 18 to deflect back and forth, thereby realizing the hydraulic control of the hammer 17 to strike through the transmission cylinder 9.

[0065] When the top pressure inclined plate 18 reciprocates, the hammer 17 is controlled to strike the inner wall of the transmission cylinder 9, causing the transmission cylinder 9 and the crushing teeth 10 to vibrate, thereby improving the crushing efficiency and preventing material from sticking together.

[0066] In a preferred embodiment of the present invention, a support cylinder 33 is rotatably installed on the inner wall of the storage box 7. The support cylinder 33 is a hollow cylinder to facilitate the passage of spray liquid.

[0067] A filter cylinder 26 is fixedly installed on the outer wall of the support cylinder 33. The filter cylinder 26 is designed to filter out small impurities in the liquid inside the storage tank 7.

[0068] The axial end of the support cylinder 33 is connected to a rigid tube 23 via a sealed bearing. The rigid tube 23 passes through the storage tank 7 and is connected to the input end of the control pump 8. When the control pump 8 is working, the liquid inside the storage tank 7 is filtered through the filter cylinder 26 and then enters the inner cavity of the support cylinder 33. It then enters the control pump 8 through the rigid tube 23 to realize the delivery of the spray liquid.

[0069] A collection box 24 is detachably installed on the inner wall of the storage tank 7. The upper end of the collection box 24 is provided with an opening. A scraper 34 is fixedly installed on the inner wall of the collection box 24. The other end of the scraper 34 is attached to the outer wall of the filter cartridge 26. When the control pump 8 is working, the control support cylinder 33 rotates, which drives the filter cartridge 26 to rotate. At this time, the scraper 34 scrapes the impurities adsorbed on the surface of the filter cartridge 26 and makes them fall into the inner cavity of the collection box 24, thereby cleaning the filter cartridge 26. This ensures that the control pump 8 always draws clean liquid from the storage tank 7 when it is working, preventing impurities from entering the control pump 8 with the liquid and causing wear, or clogging the subsequent pipeline and affecting the stability of water pressure, while maintaining the filtration efficiency of the filter cartridge 26.

[0070] The collection box 24 is slidably inserted into the storage box 7, and a sealing gasket is provided at the connection position. By pulling out the collection box 24, it is easy to discharge the impurities collected inside the collection box 24.

[0071] A baffle plate 32 is fixedly installed on the outer wall of the rigid tube 23. The outer wall of the baffle plate 32 is in contact with the inner wall of the support cylinder 33 and is directly opposite the upper opening of the collection box 24. This reduces the impact of suction on impurities inside the collection box 24 when the control pump 8 is working, prevents impurities inside the collection box 24 from re-adhering to the surface of the filter cylinder 26 and prevents impurities inside the collection box 24 from escaping. While maintaining the cleanliness of the filter cylinder 26, it also reduces the impurity content in the liquid inside the storage tank 7. This reduces the impact of impurities on various components during liquid circulation from the source. For example, it prevents impurities from adhering to the inner wall of the transmission cylinder 9 and affecting the cooling effect, or from adhering to the surface of the crushing teeth 10 with the sprayed liquid and interfering with the shredding operation of the silent plastic tube. Combined with the design of the baffle plate 32 to prevent impurities from escaping from the collection box 24, it not only ensures the cleanliness of the liquid, but also extends the service life of core components such as the control pump 8 and the filter cylinder 26, ensuring the stable operation of the entire crushing system.

[0072] A control motor 11 is fixed to the outer wall of the storage box 7. The output shaft of the control motor 11 extends to the inner wall of the storage box 7 and is fixedly installed with a top pressure cam 25. A sealed bearing is provided at the contact position between the output shaft of the control motor 11 and the inner wall of the storage box 7. The top pressure cam 25 is controlled by the control motor 11.

[0073] A support plate 28 is fixedly installed on the inner wall of the storage box 7. A sliding frame 29 is elastically connected to the support plate 28. The sliding frame 29 passes through the support plate 28 and is slidably connected to the support plate 28. A spring is provided on the outer wall of the sliding frame 29, and the other end of the spring is fixedly connected to the outer wall of the support plate 28.

[0074] A contact block 27 is fixedly installed at one end of the sliding frame 29. The top pressure cam 25 is used to strike the contact block 27. In the initial state, the top pressure cam 25 and the contact block 27 are not in contact. As the top pressure cam 25 rotates, the top pressure cam 25 strikes the contact block 27 and continues to push the contact block 27 to make the sliding frame 29 slide until the contact block 27 separates from the top pressure cam 25. At this time, the spring force controls the sliding frame 29 to reset, which is used to control the horizontal plate 30 to slide back and forth and stir the liquid in the storage tank 7.

[0075] The limiting plate 15 restricts the horizontal plate 30 to deflect in one direction, which facilitates the flow of liquid toward the filter cartridge 26 to adsorb and capture impurities. At the same time, the ripples generated by the liquid and the shaking caused by the impact of the top pressure cam 25 on the contact block 27 can also drive the guide frame 3 to shake, so that the shredded material can be discharged.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
