Device for processing polyethylene particles by using waste double-wall corrugated pipe

Abstract

The invention discloses a device for processing polyethylene particles by using a waste double-wall corrugated pipe, and belongs to the technical field of recycling. The device comprises a screw extruder, wherein a connected crushing box is arranged at the upper end of the screw extruder, and a heating tube is arranged on the inner side wall of the screw extruder. The device filters exhaust gas inthe production process through a filter cartridge in a purification filter assembly and then discharges the exhaust gas to the environment. A glass fiber mat layer, a metal sintered mesh layer, a glass fiber filter layer and an activated carbon layer inside filter cartridge effectively adsorb and filter the exhaust gas, ensuring the cleanness of the exhaust gas and avoiding pollution to the environment. At the same time, the filter cartridge is simple and convenient to install and dismantle, and is convenient to clean, and the internal filter net layer is convenient to replace. The polyethylene melt stream is formed first and then cooled by a forming component, which reduces a series of steps such as the traditional thin strip cooling and then coiling, and disadvantages such as the thin strip breaking during the coiling process, thereby improving production efficiency.

Description

technical field [0001] The invention belongs to the technical field of recycling, and in particular relates to a device for processing polyethylene particles by using waste double-wall corrugated pipes. Background technique [0002] High-density polyethylene double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. It was first successfully developed in Germany in the early 1980s. After more than ten years of development and improvement, it has developed from a single variety to a complete one. At present, the production process and application technology are very mature. Due to its excellent performance and relatively economical cost, it has been greatly promoted and applied in developed countries such as Europe and the United States. Waste double-wall corrugated pipes are recycled Utilization can not only greatly save resources, but also reduce environmental pollution and improve the quality of the ecological environment. The...

[0002] High-density polyethylene double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. It was first successfully developed in Germany in the early 1980s. After more than ten years of development and improvement, it has developed from a single variety to a complete one. At present, the production process and application technology are very mature. Due to its excellent performance and relatively economical cost, it has been greatly promoted and applied in developed countries such as Europe and the United States. Waste double-wall corrugated pipes are recycled Utilization can not only greatly save resources, but also reduce environmental pollution and improve the quality of the ecological environment. The dust exhaust gas is directly discharged into the air, which affects the air quality and the working environment of the staff. At the same time, the melted plastic is extruded from the die to form thin strips, and then the thin strips are cooled by air or water, then coiled and cut by a pelletizer. Plastic particles, in this process, the thin strips are easy to break, the production efficiency is low, and the thin strips will produce smoke when air or water cooling, the smoke is easy to float around, polluting the working environment
