Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE material recycling technology, specifically a PE material recycling granulation device. Background Technology
[0002] PE material recycling refers to a process of recycling and reusing waste polyethylene (PE) products. As a common plastic material, PE is widely used in packaging, construction, pipelines and many other fields. With the increase in its usage, a large amount of waste PE material has put considerable pressure on the environment. Therefore, recycling PE material is of great significance. Granulation equipment is needed in the recycling and processing of PE material. Granulation equipment can granulate the recycled PE material before it can be put into use, thereby enabling the recycling and reuse of waste PE products.
[0003] While traditional granulation equipment has granulation capabilities, it also has some shortcomings. For example, its heating component has a relatively fixed and integral structure, making it difficult to disassemble and maintain the damaged part when the heating component is partially damaged. This can affect the heating effect and severely impact the melting state of the PE material, resulting in poor subsequent granulation quality. In addition, its cooling effect on the particles after granulation is poor, which can easily cause the extruded particles to deform or stick together due to insufficient cooling and shaping, thus affecting the granulation quality. Therefore, a PE material recycling granulation device is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a PE material recycling and granulation device. Its heating component has a flexible and modular structure, so when the heating component is partially damaged, the damaged part can be disassembled and maintained locally. This prevents the heating effect from affecting the melting state of the PE material and avoids poor subsequent granulation quality. In addition, it has a better cooling effect on the particles after granulation, thus preventing the extruded particles from deforming or sticking together due to failure to cool and form in time. This ensures the granulation quality and solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0010] Preferably, the cooling assembly includes a cooling machine fixedly connected to the bottom of the front wall of the collection box and cooling chambers symmetrically opened on both sides of the collection chamber. Cooling pipes are symmetrically connected to the output end of the cooling machine.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In this invention, the base provides excellent support and structural stability, the fixed support plate secures the barrel to ensure stable operation, the feed hopper introduces PE material into the barrel, the screw conveyor transports the PE material, and the heating assembly heats the barrel, causing the PE material to gradually melt as it is conveyed by the screw conveyor, thus achieving the desired granulation process.

The connecting bolts 606 are positioned and matched with the connecting screw holes 607. The heating component 6 can heat the barrel 3, causing the PE material to gradually melt during the conveying process of the screw conveyor 4 within the barrel 3, thus achieving the subsequent granulation state. Furthermore, the heating component 6 has a flexible and modular structure, allowing for partial disassembly and maintenance when damaged, preventing the heating effect from affecting the melting state of the PE material and avoiding poor subsequent granulation quality.

[0027] Workflow: First, power on all electrical appliances and connect them to external controllers. Base 1 provides good support and structural stability for the whole structure. Fixed support plate 2 provides fixed support for barrel 3 to ensure stable operation. Feed box 5 introduces PE material into barrel 3. Screw conveyor 4 transports the PE material into barrel 3. Resistance heating block 603 in heating assembly 6 heats barrel 3, causing the PE material to gradually melt as it is conveyed by screw conveyor 4, achieving the subsequent granulation state. Heating assembly 6 has a flexible and modular structure, allowing for partial disassembly and maintenance when damaged, preventing the heating effect from affecting the melting state of the PE material and avoiding poor granulation quality. During installation, firstly, place the first heating cover 601 and the second heating cover 602 on both sides of barrel 3, then bring them closer together so that they are fitted over the outside of barrel 3.

The collection chamber 10 in the collection box 9 can collect the extruded particles for subsequent processing. The cooler 1101 in the cooling assembly 11 can cool the outside air through the compressor, which then enters the cooling duct 1103 and is finally blown out through the cooling nozzle 1104. The blown cold air can cool the particles that enter the collection chamber 10 after extrusion, thus preventing the extruded particles from deforming or sticking together due to not being cooled and formed in time, thereby ensuring the granulation quality. The ventilation mesh plate 1105 can prevent particles from entering the cooling chamber 1102 and affecting the cooling nozzle 1104 while ensuring ventilation.
