Description

Technical Field

[0001] The present invention relates to the technical field of waste plastic recycling, and in particular to a plastic particle production device for waste material recycling and a use method thereof. Background Art

[0002] At present, plastic particles are a raw material for producing various plastic products. The materials of plastic particles are diverse. Plastic particle production equipment is needed to produce plastic particles. The plastic particle production equipment melts the raw materials of plastic particles and then extrude and cut the molten plastic particle raw materials into plastic particles. Existing plastic particle production equipment usually produces some oversized plastic particles during production. Oversized plastic particles are difficult to use directly. Usually, the oversized plastic particles need to be manually sorted and recycled, which is troublesome.

[0003] There are many existing technologies for recycling waste plastics, such as:

[0004] Chinese patent publication number CN115609785A discloses a plastic particle production device, including a feed box, a feed pipe is connected to the top of the feed box, a cutting box is connected to the bottom of the feed box, a heating plate is attached to the inner wall of the feed box, a stirring component is arranged inside the feed box, the stirring component is used to stir the raw materials inside the feed box, a distribution box, the distribution box is connected to the bottom of the cutting box, a screen is arranged inside the distribution box, the screen is inclined, and the screen is used to screen the particles, a support frame, the distribution box is connected to the right side of the top of the support frame, a sorting component is arranged on the right side of the distribution box, the sorting component is used to sort the particles entering the distribution box, and a discharge pipe connected to the inside of the distribution box is inserted at the lower end of the distribution box; the present invention sorts plastic particles with larger sizes by the sorting component, and then recycles the plastic component by the recycling component.

[0005] It can be seen that when most plastic particle production equipment recycles waste plastics, the plastic particles will be of different sizes during the production process, and large-sized plastic particles need to be screened and crushed. However, since plastic particles are soft materials, they will be squeezed against each other during the screening process, causing them to be blocked at the screen, resulting in the subsequent production of plastic particles unable to pass through the screen to complete the screening operation. In addition, if the filter holes below the crushing device are blocked, the plastic particles cannot be detached after being crushed, causing serious material retention inside the box.

[0006] In view of this, the present invention provides a plastic particle production device for waste recycling and a method of using the same. Summary of the invention

The water flows over the water level line, so that the plastic particles rise to the accumulation height in the receiving tank through buoyancy. At the same time, the water flow is pushed toward the filter hole during the rotation process to release the blocked plastic particles, and prevent the plastic particles from clogging the water outlet during the pumping process.

[0013] As a further improvement of the technical solution, a filter screen is provided inside the supporting and stabilizing processing box, and a vibration motor for driving the filter screen to vibrate is installed on the surface of the supporting and stabilizing processing box.

[0045] Plastic particles are a raw material for producing various plastic products. The materials of plastic particles vary. Plastic particle production equipment is needed to produce plastic particles. The plastic particle production equipment melts the raw materials of plastic particles and then extrude and cut the molten plastic particle raw materials into plastic particles. Existing plastic particle production equipment usually produces some oversized plastic particles during production. Oversized plastic particles are difficult to use directly. Usually, the oversized plastic particles need to be manually sorted and recycled, which is troublesome.

[0046] See also Figure 1-Figure 10 As shown, one of the purposes of this embodiment is to provide a plastic particle production device for waste recycling;

[0047] It includes a supporting and stabilizing processing box 11, and an extrusion processing screening component 20 is provided on the surface of the supporting and stabilizing processing box 11. The extrusion processing screening component 20 is used to heat the waste plastics and form plastic particles to be discharged into the supporting and stabilizing processing box 11, and at the same time, the plastic particles are screened by vibration;

[0048] A cutting and crushing assembly 30 is provided inside the supporting and stabilizing processing box 11. The cutting and crushing assembly 30 is used to push the plastic particles in the screening process, so that the plastic particles that have not passed the screening are accumulated in the receiving tank, and the accumulated plastic particles are crushed. A screening and water injection cleaning assembly 40 is provided inside the supporting and stabilizing processing box 11. The screening and water injection cleaning assembly 40 is used to evenly distribute the plastic particles that will pass the screening through rotation, and to inject water into the supporting and stabilizing processing box 11. The water flows over the water level line, so that the plastic particles rise to a stacking height in the receiving tank through buoyancy. At the same time, the water flow is pushed toward the filter hole during the rotation process to release the blocked plastic particles and prevent the plastic particles from clogging the water outlet during the pumping process.

[0049] In the production process of plastic particles, different sizes will appear, and large-sized plastic particles need to be screened and crushed. However, since plastic particles are made of soft materials, they will be squeezed against each other during the screening process, resulting in blockage at the screen, so that the subsequently produced plastic particles cannot pass through the screen to complete the screening operation, and if the filter holes below the crushing device are blocked, the plastic particles cannot be separated after being crushed, resulting in serious material retention inside the box. Therefore, the extrusion processing screening component 20 includes a feed hopper 21, which is installed on the surface of the supporting and stabilizing processing box 11, and an extruder 22 is installed at the bottom of the feed hopper 21. The bottom of the extruder 22 is connected to a discharge port 23. The feed hopper 21, the extruder 22 and the discharge port 23 are connected. A cutter is provided inside the discharge port 23 for cutting the extruded plastic particles into sections. A filter screen 24 is provided inside the supporting and stabilizing processing box 11, and a vibration motor 25 for driving the filter screen 24 to vibrate is installed on the surface of the supporting and stabilizing processing box 11.

[0050] The cutting and crushing assembly 30 includes an intercepting plate 31, which is installed inside the supporting and stabilizing processing box 11. A cutting knife 32 is rotatably connected inside the supporting and stabilizing processing box 11. A rotating motor 33 for driving the cutting knife 32 to rotate is installed on the surface of the supporting and stabilizing processing box 11. A first gear 34 is rotatably connected inside the supporting and stabilizing processing box 11. A second gear 35 is rotatably connected inside the supporting and stabilizing processing box 11. A driving device for driving the first gear 34 and the second gear 35 to rotate is provided inside the supporting and stabilizing processing box 11. Chains 36 are meshed on the surfaces of the first gear 34 and the second gear 35. A connecting plate 37 is installed on the surface of the chain 36. An elastic member 38 is installed inside the connecting plate 37. The other end of the elastic member 38 is connected to a pushing plate 39. The pushing plate 39 and the connecting plate 37 are slidably connected to limit the vertical movement of the pushing plate 39.

[0051] Depend on Figure 2-Figure 8 As shown, when the waste plastic needs to be recycled, the waste plastic is first placed in the feed hopper 21, and the waste plastic enters the extruder 22 through the feed hopper 21, and then the extruder 22 is started to work, and the extruder 22 works to melt the waste plastic and extrude the melted material to the discharge port 23, and then the plastic particles extruded from the surface of the discharge port 23 are cut by the cutter inside the supporting and stabilizing processing box 11, so that the plastic particles fall into the surface of the filter screen 24 for screening;

[0052] Then the vibration motor 25 is started to work, and the vibration motor 25 drives the filter screen 24 to vibrate, and the filter screen 24 vibrates so that the plastic particles smaller than the filter holes on the surface of the filter screen 24 pass through. Figure 6 As shown, the filter screen 24 is installed on an inclined surface. When the plastic particles are vibrated during the screening process, the plastic particles that have not passed the screening are moved toward the cutting knife 32. At the same time, the driving device supporting the stable processing box 11 is started to work, so that the first gear 34 and the second gear 35 rotate. The rotation of the first gear 34 and the second gear 35 drives the chain 36 to move. The movement of the chain 36 causes the connecting plate 37 to move. During the movement of the connecting plate 37, the elastic member 38 generates elastic force to push the push plate 39 downward. The push plate 39 moves in contact with the filter screen 24, thereby pushing the plastic particles that have not passed the filter screen 24 on the surface to move quickly to the receiving groove, thereby ensuring the number of filter holes on the surface of the filter screen 24 that can pass through, and avoiding the accumulation of plastic particles below the discharge port 23, which affects the screening speed of the plastic particles by the device;

[0053] Since the plastic particles fall vertically after screening, they will accumulate under the screen and cannot be evenly distributed inside the supporting stable processing box 11. When the height of the accumulation fits the screen, the plastic particles cannot pass through, resulting in frequent material removal operations and a small amount of processing volume at one time. Therefore, the screening water injection cleaning component 40 includes an electric rotating plate 41, which is rotatably connected to the supporting stable processing box 11. A rubber pad is provided on the surface of the electric rotating plate 41 to prevent water from leaking out. A first electric rotating rod 42 is rotatably connected to the surface of the electric rotating plate 41. The surface of the rotating plate 41 is rotatably connected with a second electric rotating rod 43, and a corrugated water pipe 44 is installed at the bottom of the electric rotating plate 41. The water outlet of the corrugated water pipe 44 is within the rotation range of the first electric rotating rod 42 and the second electric rotating rod 43. The other end of the corrugated water pipe 44 is connected to a water storage tank 45. A water pump is installed inside the water storage tank 45 to inject and extract water into and out of the supporting stable processing box 11 through the corrugated water pipe 44. A fixing frame 46 is installed on the surface of the water storage tank 45, and the fixing frame 46 is connected to the supporting stable processing box 11, so that the supporting stable processing box 11 is suspended and stable.

[0054] The rotating motor 33 is started to work, and the rotating motor 33 drives the cutting blade 32 to rotate. The cutting blade 32 rotates to break the plastic particles inside the receiving groove, so as to meet the standard of passing through the filter screen 24, thereby preventing the plastic particles from being too large to pass through the filter screen 24 and accumulating, thereby affecting the subsequent screening efficiency. Then, when it is necessary to take out the screened plastic particles, the first electric rotating rod 42 and the second electric rotating rod 43 are started to work, and the first electric rotating rod 42 and the second electric rotating rod 43 work to push the plastic particles that fall on the surface of the electric rotating plate 41 to the left and right sides, so that the plastic particles are evenly distributed on the surface of the electric rotating plate 41. Then, the electric rotating plate 41 is started to work, and the electric rotating plate 41 works and rotates to make the plastic particles fall downward and break away from the supporting stable processing box 11, thereby completing the material removal of the plastic particles.

[0055] Depend on Figure 5-Figure 10 As shown, when the filter screen 24 is blocked, the water pump inside the water tank 45 is started to work. When the water pump inside the water tank 45 works, the water flow of the water tank 45 is input from the corrugated water pipe 44 to the inside of the supporting stable processing box 11. Then, the first electric rotating rod 42 and the second electric rotating rod 43 rotate to push the water flow to move. The moving water flow will move upward through the filter holes of the filter screen 24. The moving water flow will push the plastic particles blocked in the filter holes of the filter screen 24, so that the plastic particles are separated and rise to the water surface through the automatic buoyancy of the plastic particles. At the same time, the plastic particles accumulated under the receiving tank move upward through the buoyancy, increasing the contact area with the cutting knife 32, so that the cutting knife 32 can quickly crush the plastic particles.

[0056] Depend on Fig.10 As shown, when it is necessary to recycle the water inside the supporting and stabilizing processing box 11, the second electric rotating rod 43 and the first electric rotating rod 42 will work to push the plastic particles blocked on the surface of the corrugated water pipe 44, so that the water flow can be quickly recovered through the corrugated water pipe 44, avoiding the plastic particles from clogging the corrugated water pipe 44 and causing the water flow to be retained inside the supporting and stabilizing processing box 11.

[0057] The second purpose of this embodiment is to provide a method for using a plastic particle production device for waste recycling, comprising the following method steps:

[0058] S1, the waste plastic is processed into plastic particles by the extrusion processing screening component 20, and then the cutting and crushing component 30 screens and crushes the plastic particles;

[0059] S2, the screening and water injection cleaning component 40 cleans the blocked plastic particles and evenly distributes the plastic particles that have passed the screening. Finally, the plastic particles are discharged from the bottom of the supporting and stabilizing processing box 11 through the screening and water injection cleaning component 40.

[0060] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.

The moving water flow pushes the plastic particles clogged in the filter holes of the filter screen (24), causing the plastic particles to break away and rise to the water surface through the automatic buoyancy of the plastic particles. At the same time, the plastic particles accumulated under the receiving tank move upward through the buoyancy, increasing the contact area with the cutting knife (32), so that the cutting knife (32) can quickly crush the plastic particles. S5. When it is necessary to recycle the water inside the supporting and stabilizing processing box (11), the second electric rotating rod (43) and the first electric rotating rod (42) will work to push the plastic particles that are blocked on the surface of the corrugated water pipe (44), so that the water can be quickly recycled through the corrugated water pipe (44), thereby preventing the corrugated water pipe (44) from being blocked by plastic particles and causing the water to be retained inside the supporting and stabilizing processing box (11).
