Description

Technical Field

[0001] This utility model relates to the field of PET waste recycling and treatment technology, specifically a PET waste recycling and treatment device. Background Technology

[0002] Since the waste generated after processing polyethylene terephthalate (PET) is usually not effectively treated, it is necessary to recycle and reuse it in order to avoid environmental pollution. This can also save resources and reduce costs. In the recycling process, commonly used equipment includes waste crushing and processing equipment.

[0003] Currently available PET waste recycling and processing devices mainly use the cyclone cutting force generated by the rotation of built-in blades to crush PET waste. However, considering that PET waste is prone to static electricity after crushing, PET fragments are easily stuck to the blades due to static electricity during the actual crushing process, which reduces the crushing efficiency of the blades in subsequent PET waste processing and also affects the feeding efficiency of PET fragments. Therefore, a PET waste recycling and processing device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a PET waste recycling and processing device to solve the problem mentioned in the background art that PET fragments easily adhere to the cutting tools due to static electricity when using existing PET waste recycling and processing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PET waste recycling and processing device includes a crusher box. Inner inclined plates are fixedly connected to the upper sides of both sides of the crusher box. An auxiliary support plate is fixedly connected to the bottom of the inner inclined plates. An ion fan, fixedly installed together with the crusher box, is disposed in the gap between the auxiliary support plate and the inner inclined plates. An adapter is connected to the top center of the auxiliary support plate, and an air outlet is connected to the bottom of the auxiliary support plate. An air outlet hood is fitted over the air outlet, and side fasteners are fixedly connected to both sides of the air outlet hood. An inclined air outlet is connected to the bottom of the air outlet hood, and a fan wheel is rotatably connected to the inner side of the inclined air outlet.

[0007] Preferably, a screen is slidably connected to the lower inner side of the crusher box, and a front pull plate is provided at the front end of the crusher box directly opposite the screen, and the front pull plate and the screen are fixedly connected.

[0008] Preferably, a bracket is fixedly connected to the lower outer side of the crusher box. The bracket has a "U" shaped structure. A side top plate is fixedly connected to the top left side of the bracket. A drive motor is fixedly installed inside the frame provided on the top of the side top plate. A crushing blade body is rotatably connected to the middle position of the inner side of the crusher box. One end of the crushing blade body and the output end of the drive motor extending into the crusher box are fixedly connected together.

[0009] Preferably, the top of the crusher box is connected to a feed hopper, and the bottom of the crusher box is connected to a discharge hopper.

[0010] Preferably, a plurality of the inclined air outlets are arranged symmetrically in two rows, and the air outlets of the two rows of inclined air outlets are all inclined toward the crushing blade body. The side plate and the auxiliary support plate are detachably connected together by bolts. The air inlet of the square air outlet is connected to the air outlet of the adapter through the ventilation cavity provided inside the auxiliary support plate. The adapter and the ion fan are connected by an air outlet bend. A "V" shaped gap structure is formed between the auxiliary support plate and the inner inclined plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the ion fan, air outlet bend, adapter, air outlet square port, air outlet hood, side buckle plate, air outlet oblique port, and impeller facilitate the PET waste recycling and processing device to generate a cutting force when the crushing blade body rotates. During the crushing process of bottle-shaped PET waste, with the assistance of the inner oblique plate and auxiliary support plate, the static electricity generated during the crushing of bottle-shaped PET waste is removed by the antistatic structure composed of the ion fan, air outlet bend, adapter, air outlet square port, air outlet hood, side buckle plate, air outlet oblique port, and impeller. This prevents the crushed PET fragments from directly adhering to the surface of the crushing blade body, thus preventing fragment adhesion and affecting the crushing efficiency of subsequent PET waste processing. This also facilitates the subsequent discharge of PET fragments from the device. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution:

[0019] A PET waste recycling and processing device includes a crusher box 1. Inner inclined plates 2 are fixedly connected to the upper sides of both sides of the crusher box 1. An auxiliary support plate 3 is fixedly connected to the bottom of the inner inclined plate 2. An ion fan 4, which is fixedly installed together with the crusher box 1, is provided in the gap between the auxiliary support plate 3 and the inner inclined plate 2. An adapter 6 is connected to the middle of the top of the auxiliary support plate 3. An air outlet 7 is connected to the bottom of the auxiliary support plate 3. An air outlet hood 8 is fitted on the outside of the air outlet hood 7. Side fasteners 9 are fixedly connected to the left and right sides of the air outlet hood 8. An air outlet slant 10 is connected to the bottom of the air outlet hood 8. A fan wheel 11 is rotatably connected to the inner side of the air outlet slant 10.

[0020] like Figure 1 and Figure 2As shown, a screen 12 is slidably connected to the lower inner side of the crusher box 1. A front pull plate 13 is located at the front end of the crusher box 1, directly opposite the screen 12. The front pull plate 13 and the screen 12 are fixedly connected. After crushing bottle-shaped PET waste, the device can screen suitable PET fragments through the screening structure assembled from the screen 12 and the front pull plate 13. A bracket 14 is fixedly connected to the lower outer side of the crusher box 1. The bracket 14 has a "U" shaped structure, and a side top plate 15 is fixedly connected to the top left side of the bracket 14. A drive motor 16 is fixedly installed inside the frame at the top of the side top plate 15. A crushing blade body 17 is rotatably connected to the middle of the inner side of the crusher box 1. One side end of the crushing blade body 17 and the output end of the drive motor 16 extending into the crusher box 1 are fixedly connected together. When the crusher box 1 is started, the "U"-shaped bracket 14 provides stable support for it. The top of the crusher box 1 is connected to the feed hopper 18, and the bottom of the crusher box 1 is connected to the discharge hopper 19. The feed hopper 18 and the discharge hopper 19 are set to assist the loading and unloading of PET waste.

[0021] like Figure 2 and Figure 3 As shown, several inclined air outlets 10 are arranged symmetrically in two rows. The air outlets of the two rows of inclined air outlets 10 are all inclined towards the crushing blade body 17. The side plate 9 and the auxiliary support plate 3 are detachably connected together by bolts. The air inlet of the air outlet square port 7 is connected to the air outlet of the adapter 6 through the ventilation cavity provided inside the auxiliary support plate 3. The adapter 6 and the ion fan 4 are connected by an air outlet bend 5. A "V" shaped gap structure is formed between the auxiliary support plate 3 and the inner inclined plate 2. The arrangement of the two rows of inclined air outlets 10 inclined towards the crushing blade body 17 is conducive to the device to perform centralized static electricity removal treatment on the PET waste falling onto the crushing blade body 17.

[0022] Workflow: The electrical energy required for the device to start and operate in this utility model comes from an external power source. When using this recycling device to process PET waste, with the auxiliary support of the bracket 14 and the side top plate 15, the bottle-shaped PET waste to be processed is poured into the feed hopper 18. The bottle-shaped PET waste falls along the inclined surfaces of the two inner inclined plates 2 into the inner side of the crusher box 1. At this time, as the device is driven by the rotating drive motor 16, it uses the generated rotary cutting force to cut and crush the bottle-shaped PET waste. The crushed PET fragments then fall onto the screen 12 for filtration and screening. The qualified PET fragments are discharged outwards through the discharge hopper 19. Simultaneously, for some PET fragments falling onto the screen 12, the operator can... Pull plate 13 pulls the screen 12 out from the inside of the crusher box 1 to further process some of the PET fragments that fall onto the screen 12. In addition, to address the problem of static electricity that is easily generated during the crushing of PET waste, with the assistance of the inner inclined plate 2 and the auxiliary support plate 3, two start-up ion fans 4 simultaneously generate positive and negative ions and airflow. The positive and negative ions will pass through the air outlet bend 5, the adapter 6, the auxiliary support plate 3, the air outlet square port 7 and the air outlet hood 8 in sequence with the airflow and be sent into the air outlet inclined port 10. They will be accelerated by the rotation of the impeller 11 and will be tilted towards the crushing blade body 17 and carried out. In this way, static electricity is removed during the crushing of PET waste, so as to avoid the problem of PET waste fragments being crushed into fragments and then adhering to the surface of the crushing blade body 17 due to static electricity.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
