Description

Technical Field

[0001] The invention relates to the field of polymer material production, and in particular to an intelligent heat treatment device for plastic particles. Background Art

[0002] With the increasing awareness of environmental protection and the continuous increase in the use of plastics, plastic recycling and reuse has become an important measure to alleviate resource pressure and reduce environmental pollution. The plastic recycling industry is booming, and various recycling technologies and equipment are constantly emerging. The demand for efficient and accurate processing of different types of plastic particles is becoming increasingly urgent.

[0003] At present, there are many plastic particle heat treatment devices on the market. These devices are mainly used to heat recycled mixed plastics to achieve separation and recycling of different plastics. However, most of them have simple structures and imperfect functions, and are not very effective when processing complex mixed plastics.

[0004] Existing plastic particle heat treatment devices or when recycling plastic waste usually put mixed plastics directly into heating equipment, heat them at a certain temperature, and collect them after the plastics reach their melting point. However, this method lacks the fine treatment of plastics with different melting points. During the processing, it is simply heated as a whole, without considering the further processing steps of different plastics after the properties change.

[0005] However, the existing technology cannot accurately perform layered processing based on the properties of plastics with different melting points. When mixed plastics enter the device, plastics with low and high melting points cannot be effectively separated and recycled, which easily results in low purity of the recycled plastics. Summary of the invention

[0010] By adopting the above technical solution, the plastic particles are screened through the filter plate, and the plastic particles that are easy to melt enter the device first, thereby facilitating the recycling of plastics.

[0011] The present invention is further configured such that the feeding device includes an installation groove, a feeding plate is rotatably arranged in the installation groove, the top of the feeding plate is connected to the processing opening, the bottom of the feeding plate is in contact with the supporting bottom plate, and a pair of supporting shafts are arranged at both ends of the upper limit in the installation groove to cooperate with the feeding plate, one side of the support shaft is connected to a guide shaft, and one end of the guide shaft is connected to a control motor.

[0012] By adopting the above technical solution, the motor is controlled to drive the guide shaft to rotate, and then the sign material plate is driven to rotate, so that the plastic particles are recycled.

[0013] The present invention is further configured such that a pair of support plates are provided outside the device housing to cooperate with the pair of reeling shafts, and a support rotating shaft is provided on the support plate to cooperate with the reeling shafts.

[0017] The present invention is further configured such that a plurality of hanging plates are arranged on the feeding plate.

[0022] The present invention intercepts larger particles on the conical filter plate. At the same time, the upper cover plate starts to rotate under the drive of the external transmission device. The friction plate at the bottom fully contacts and rubs with the plastic particles to grind or tear the particles, making the plastic particles more uniform in size, laying a good foundation for the subsequent recycling process. At the same time, as the conveyor belt moves back and forth, the melted plastic will adhere to its surface. When the conveyor belt passes through the limiting vertical groove, the plastic is scraped to the separation groove. In the separation groove, the melted plastic falls from the gap between the limiting rotating shafts and enters the collection groove through the leakage port, while the high melting point plastic remains on the rotating shaft, thereby realizing the precise separation and targeted recovery of plastics with different melting points.

DETAILED DESCRIPTION

[0033] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The following describes an embodiment of the present invention based on its overall structure.

[0035] An intelligent heat treatment device for plastic particles, such as Figure 1 , Figure 3 and Figure 7 As shown, it includes a device shell 1, a feed processing device is arranged on the top of the device shell 1, an inner processing tank 13 is arranged below the feed processing device in the device shell 1, a support rod 29 is arranged at the bottom of the inner processing tank 13, and the support rod 29 is arranged with a support bottom plate 30. A pair of reeling shafts 8 are symmetrically arranged outside the device shell 1, and a conveyor belt 5 is connected to the pair of reeling shafts 8. The pair of reeling shafts 8 are arranged at a certain inclination angle, and the conveyor belt 5 passes through the device shell 1 and the inner processing tank 13. A limited vertical Groove 18, a vertical material passing groove 14 is provided on the inner processing groove 13 to cooperate with the conveyor belt 5, and a pair of feeding devices are symmetrically arranged on both sides of the inner processing groove 13. In actual use, the conveyor belt 5 is driven to reciprocate by the winding shaft 8. Through such an arrangement in actual use, after the material is fed through the feeding processing device, the plastic particles are heated, and the properties of the plastic with a low melting point change, thereby resulting in enhanced fluidity and increased viscosity. When recycling plastics, different plastics are mixed into the device, and the materials are melted and recycled according to the properties of different plastics and different melting points.

[0036] For further reference, Figure 2 , Fig. 9The feed processing device includes a guide groove 11, a filter plate 10 is arranged in the guide groove 11, an upper cover plate 3 is arranged at the top of the guide groove 11, and the upper cover plate 3 is rotatably arranged in the guide groove 11, a feed opening 2 is opened on the upper cover plate 3, and an opening 9 is opened at the top of the guide groove 11 to cooperate with the processing opening 23, the filter plate 10 is arranged in a cone, and the bottom of the upper cover plate 3 is arranged in a cone to cooperate with the conical filter plate 10, and a friction plate 22 is arranged at the bottom of the upper cover plate 3 to cooperate with the filter plate 10. After the plastic particles enter the guide groove 11 through the feed opening 2, they fall onto the filter plate 10 and are filtered by the filter plate 10. At this time, the larger particles are retained on the filter plate 10. At this time, the upper cover plate 3 is rotated to drive the friction plate 22 at the bottom of the upper cover plate 3 to rub against the plastic, so that the plastic is further ground or torn, which is convenient for subsequent recycling of the plastic particles.

[0037] Further, such as Figure 5-8 The support bottom plate 30 is provided with a pair of separation grooves 19 in cooperation with the limiting vertical grooves 18. After the plastic particles enter the device, the melted plastic will adhere to the conveyor belt 5. In cooperation with this, when the conveyor belt 5 moves back and forth, in cooperation with the above-mentioned limiting vertical grooves 18, when the conveyor belt 5 carrying the plastic particles passes through the limiting vertical grooves 18, the plastic on the conveyor belt 5 will be scraped into the separation grooves 19. At this time, through the separation grooves 19, a guide frame 25 is provided at the top of the separation groove 19, and a plurality of limiting rotating shafts 26 are provided at the top of the guide frame 25. A material leakage hole is provided at the bottom of the separation groove 19. The device shell 1 is provided with a collecting tank 6 on the outside in cooperation with the leakage port 28. In actual use, the melted plastic falls onto the limiting shaft 26, and the melted plastic falls from the gap between the limiting shafts 26. At this time, the plastic with a higher melting point will remain on the limiting shaft 26, and the melted plastic will leak from the leakage port 28 into the collecting tank 6. A guide plate 27 is provided at the bottom of the collecting tank 6. A discharge port 12 is provided at the bottom of one side of the collecting tank 6 in cooperation with the guide plate 27. The molten plastic is guided by the guide plate 27 and output from the discharge port 12, so that the plastic with a lower melting point is recovered.

[0038] Based on the above structure, when recycling one type of plastic, the machine temperature can be further increased and the collecting device can be replaced to recycle another type of plastic;

[0039] Furthermore, after the plastic particles adhere to the first round of conveyor belt 5, the plastic particles with high melting point and high hardness will continue to fall onto the supporting bottom plate 30. At this time, the material on the supporting bottom plate 30 is sent back to the inner processing tank 13 by the feeding device to fall, thereby repeatedly recycling the plastic through the conveyor belt 5.

[0040] Specifically, Figure 4The feeding device includes a mounting groove 17, in which a feeding plate 20 is rotatably arranged, the top of the feeding plate 20 is connected to the processing opening 23, the bottom of the feeding plate 20 is in contact with the supporting bottom plate 30, and a plurality of hanging plates 24 are arranged on the feeding plate 20. A pair of supporting shafts 16 are arranged at the upper and lower ends of the mounting groove 17 to cooperate with the feeding plate 20, one side of the supporting shaft 16 is connected to the guide shaft 15, and one end of the guide shaft 15 is connected to the control motor 31. The guide shaft 15 is driven to rotate by the control motor 31, thereby driving the feeding plate 20 to rotate, and then driving the hanging plate 24 on the surface of the feeding plate 20 to move. When the hanging plate 24 passes the bottom of the supporting bottom plate 30, the material at the bottom of the supporting bottom plate 30 will be brought up, and then the operation of plastic recycling will be repeated. In particular, the supporting bottom plate 30 is arranged to be conical, so as to guide the particles for easy collection.

[0041] A pair of support plates 7 are provided outside the device housing 1 to cooperate with a pair of winding shafts 8. A support shaft 21 is provided on the support plate 7 to cooperate with the winding shaft 8. The support shaft 21 is supported by the support plate 7, so that the winding shaft 8 rotates and drives the conveyor belt 5 to move, thereby recycling the plastic.

[0042] A transmission gear 4 is arranged around the feeding opening 2 on the top of the upper cover plate 3 , and the transmission gear 4 is connected to an external transmission device. The upper cover plate 3 is driven to rotate by the rotation of the transmission gear 4 , thereby processing the material.

[0043] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
