Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, specifically to a high-efficiency integrated mechanical processing device for dust removal and resource recycling. Background Technology

[0002] Polyethylene (PE) is a thermoplastic resin obtained by polymerizing ethylene. In the plastics industry, PE has the largest production volume, the widest application, and the largest consumption, resulting in a large amount of waste polyethylene generated annually. Due to the molecular structure of polyethylene, waste polyethylene is difficult to degrade in the natural environment, causing pollution. With the continuous expansion of the polyethylene consumer market and the increasing variety and quantity of polyethylene-based consumer products, the amount of waste polyethylene is also increasing daily. Therefore, the recycling of waste polyethylene is a key aspect of waste plastics recycling.

[0003] In my country, the main methods for disposing of waste polyethylene are: landfill, incineration, chemical degradation, and recycling. Recycling refers to the process of using waste plastic products to obtain recycled materials through sorting, cleaning, granulation, and other processes. Because this method is environmentally friendly and energy-saving, it is currently the most commonly used method.

[0004] Currently, waste plastics are typically shredded during recycling to facilitate recovery and reprocessing. Since dust is emitted during shredding, dust collection equipment is usually used in conjunction with the shredding process. However, existing shredding and dust collection equipment are separate structures, which not only occupy too much space, hindering installation and use, but also result in low dust collection efficiency and frequent replacement of filter elements and bags, causing inconvenience. Therefore, this paper proposes a high-efficiency integrated mechanical processing device for dust collection and resource recovery. Summary of the Invention

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-5 This invention provides a technical solution: a high-efficiency integrated mechanical processing device for dust removal and resource recycling, comprising a base 1, a recycling cylinder 2, a feeding mechanism 3, a crushing mechanism 4, and a dust removal mechanism 5. The recycling cylinder 2 is fixedly connected to the surface of the base 1. A feeding box 6 is provided at the top of the recycling cylinder 2. The feeding mechanism 3 is provided inside the feeding box 6. A crushing chamber 7 is provided inside the recycling cylinder 2. A fixed blade holder 8 is fixedly connected to the inner wall of the crushing chamber 7. The crushing mechanism 4 is provided inside the crushing chamber 7. The dust removal mechanism 5 is fixedly connected to the top of the recycling cylinder 2 and is connected to the recycling cylinder 2. A discharge port 9 is provided at the bottom of the recycling cylinder 2. A discharge pipe 10 is fixedly connected to the bottom of the base 1 and is connected to the discharge port 9.

[0024] In a further improvement, the feeding mechanism 3 includes an active crushing roller 11, a driven crushing roller 12, a motor 13, and a gear set 14. The active crushing roller 11 and the driven crushing roller 12 are located inside the feeding box 6 and are rotatably connected to the feeding box 6. The ends of the active crushing roller 11 and the driven crushing roller 12 are provided with meshing gear sets 14. The motor 13 is fixedly connected to the outer wall of the feeding box 6, and the output end of the motor 13 is connected to the shaft of the active crushing roller 11. By providing the active crushing roller 11 and the driven crushing roller 12 rotatably connected inside the feeding box 6, it is convenient to pre-crush large-volume plastic products, which facilitates subsequent crushing processing.

[0025] In a further improvement, the active crushing roller 11 and the driven crushing roller 12 are distributed in parallel to each other, and a number of crushing teeth 15 are fixedly connected to the surfaces of the active crushing roller 11 and the driven crushing roller 12. By providing crushing teeth 15 on the surfaces of the active crushing roller 11 and the driven crushing roller 12, it is convenient to simply crush large-volume waste plastic materials and to feed them into the crushing mechanism 4.

[0026] In a further improvement, the crushing mechanism 4 includes a second motor 16, a rotating disk 17, crushing blades 18, and a central shaft 19. The central shaft 19 passes through the center of the crushing chamber 7 and is rotatably connected to the crushing chamber 7. One end of the central shaft 19 is fixedly connected to the rotating disk 17, and the other end is connected to the output end of the second motor 16. The crushing blades 18 are fixedly connected to the edge of the rotating disk 17. By providing crushing blades 18 on the surface of the rotating disk 17, it is convenient to further crush plastic fragments in conjunction with the fixed blade holder 8 during rotation, which facilitates the recycling of waste plastic materials.

[0027] In a further improvement, the fixed blade holder 8 is composed of several parallel fixed blades 20 and fixed seats 21. The fixed base 21 is fixedly connected to the root of the fixed blade 20. The fixed blades 20 and the crushing blades 18 are distributed alternately. By using parallel fixed blades 20 to form the fixed blade holder 8, it is convenient to shear and crush the material during the rotation of the crushing blades 18, thereby improving the crushing efficiency.

[0028] In a further improvement, the dust removal mechanism 5 includes a fan 22, a separation cylinder 23, a dust removal cylinder 24, and a guide pipe 25. The separation cylinder 23 is fixedly connected to the inner wall of the recovery cylinder 2, and an air inlet groove 26 is provided between the separation cylinder 23 and the crushing chamber 7. The dust removal cylinder 24 is fixedly connected to the outer wall of the recovery cylinder 2, the fan 22 is fixedly connected between the separation cylinder 23 and the dust removal cylinder 24, and the guide pipe 25 is fixedly connected to the bottom of the separation cylinder 23 and communicates with the discharge pipe 10. By using the separation cylinder 23 and the dust removal cylinder 24 to filter dust, large particulate waste can be recovered on the one hand, and the exhaust air can be filtered on the other hand, avoiding the impact on the processing environment.

[0029] In a further improvement, a conical cylinder 27 is fixedly connected to the lower end of the separation cylinder 23, and a central tube 28 is fixedly connected to the center of the separation cylinder 23. The lower end of the central tube 28 extends into the conical cylinder 27 and the upper end is connected to the air inlet of the fan 22. By providing a conical cylinder 27 at the lower end of the separation cylinder 23, in conjunction with the centrally fixedly connected central tube 28, it is convenient to rotate and separate the air containing dust, so that larger particles are separated from the bottom of the conical cylinder 27, and the air containing fine particles is sent into the dust collector 24 for further treatment.

[0030] Specifically, the dust collector 24 is fixedly connected to staggered air guide plates 29, and dust removal liquid 30 is injected into the bottom of the dust collector 24. The liquid level of the dust removal liquid 30 does not exceed the lower edge of the air guide plates 29. By providing air guide plates 29 inside the dust collector 24 and filling it with dust removal liquid 30, it is convenient for fine particulate matter in the air to dissolve in the dust removal liquid 30, thereby improving the cleanliness of the discharged air.

[0031] In operation, recyclable waste is fed into the feed hopper 6. Motor 13, under the control of the controller, rotates, driving the active crushing roller 11 and the driven crushing roller 12 to rotate, initially crushing the material into small pieces, which are then directly fed into the crushing chamber 7. The crushed material falls onto the surface of the fixed blade holder 8. Motor 2, under the control of the controller, drives the central shaft 19 to rotate, causing the crushing blades 18 to rotate at high speed. The crushing blades 18, in conjunction with the fixed blades 20, further shear and crush the pieces, further reducing the volume of the waste. The crushed waste is discharged through the discharge port 9. During the crushing process, the blower 22 always works, keeping the crushing chamber 7 under negative pressure. This draws dusty air into the separator 23, where the high-speed airflow rotates along the inner wall of the separator 23, brushing larger particles onto the inner wall of the cone 27 and sending them into the discharge port 9 along the guide pipe 25. Dust that cannot be separated is carried by the air along the central pipe 28 into the dust collector 24. The discharged air is blown into the dust removal liquid 30 along the guide plate 29, causing the dust removal liquid 30 to splash and fill the dust collector 24 with water mist. This dissolves the fine particles in the air into the dust removal liquid 30, preventing the dusty air from being discharged.

[0032] The problem solved by this invention is that existing waste plastics are usually crushed during recycling to facilitate recycling and reprocessing. Since dust is emitted during the crushing process, dust removal equipment is typically used in conjunction with it. However, existing crushing and dust removal equipment are separate structures, which not only occupy too much space, making installation and use difficult, but also have low dust removal efficiency, requiring frequent replacement of filter elements and bags, causing inconvenience. This invention utilizes a base 1, a recycling cylinder 2, a feeding mechanism 3, a crushing mechanism 4, and a dust removal mechanism 5 to form an integrated mechanical processing device. This facilitates the crushing and recycling of waste materials, making rational use of resources, while simultaneously separating and recovering the particulate matter emitted during the crushing process, avoiding air pollution. Furthermore, the structure is more compact, easy to install, and improves dust removal efficiency.
