[0002] Extruder is a type of plastic machinery. Its main function is to transform solid plastic into a uniform melt by heating, pressurizing and shearing, and then send the melt to the next process. In the process of melting solid plastic, corresponding waste gas will inevitably be generated. Due to the different components of waste gas, the waste gas generated by factory plastic extruders is mostly volatile organic waste gas and malodorous gas. The waste gas contains toxic substances, has a noticeable odor, and will produce various dusty waste gases.

[0003] In this regard, China's patent application number: CN217797978U, discloses a dust removal device for an extruder, including a smoke absorption initial section, a reversing bend section, a dust removal straight section, a guide bend section, and a tail section.

The smoke absorption initial section, the reversing bend section, the dust removal straight section, the guide bend section, and the tail section are internally connected. The utility model optimizes the setting of the dust removal device of the extruder, changes the traditional way of directly treating the dust through the exhaust gas treatment device, and improves it into a separate dust removal device. The utility model has a simple structure and low manufacturing cost, and an additional pressurization structure is added to quickly absorb the smoke. In addition, the dust is filtered by two main methods of self-sedimentation and wind pressure. The structural design consists of a dust removal plate that can be pulled out and replaced, with lower maintenance cost and better effect, and is suitable for popularization and use.

[0004] However, when the reversing bend is in use, smoke will accumulate at the bend, which will easily accumulate a lot of dust and make it difficult to clean up later. At the same time, the smoke cannot control the flow speed of the device when it is flowing, and it is troublesome to clean the dust removal plate. Therefore, it has become an urgent problem to be solved to improve and perfect the above problems. Utility Model Content
