Description

Technical Field

[0001] The utility model relates to the technical field of polyolefin particle processing, in particular to a degassing device for polyolefin particle processing. Background Art

[0002] The degassing device for polyolefin pellet processing is a kind of equipment for removing the gas contained in the polyolefin pellets during the processing. Since the polyolefin pellets will absorb certain gases during the production and processing, if these gases are not removed, the processing quality of the polyolefin pellets will be affected, such as affecting the mechanical properties and dimensional stability of the products. Therefore, in the processing of polyolefin pellets, it is very necessary to use a degassing device to degas the pellets. During the degassing process, the polyolefin is sent to the degassing bin, and the gas in the bin is extracted through the vacuum system. At the same time, the heating system is heated to promote the release of the internal gas. The control system is responsible for monitoring and controlling the entire degassing process to ensure the stability and reliability of the degassing effect. The application of the degassing device for polyolefin pellet processing not only improves the processing quality of polyolefin pellets, but also improves the quality of products, meeting the demand for high-quality polyolefin products. At the same time, its efficient and stable degassing performance also brings higher production efficiency and economic benefits to production enterprises.

[0003] Traditional degassing devices for polyolefin particle processing mainly rely on heating and stirring to promote the degassing of polyolefins. However, this traditional degassing device has some problems. First, the degassing speed is slow and the efficiency is low, which leads to a longer production cycle and affects the overall production efficiency. Secondly, the traditional degassing device can only perform horizontal stirring and cannot achieve three-dimensional stirring, resulting in uneven heating. This uneven heating method can easily cause the polyolefin raw materials to overheat and deform, thereby affecting the quality of the final product. In addition, due to the uneven heating, the degassing effect of the polyolefin particles will also be affected, resulting in poor degassing effect. Utility Model Content
