Description

Technical Field

[0001] The invention relates to the technical field of particle conveying, in particular to polytetrafluoroethylene particle conveying equipment. Background Art

[0002] Polytetrafluoroethylene, commonly known as the "king of plastics", is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. It is white waxy, translucent, and has excellent heat and cold resistance. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and its friction coefficient is extremely low. Therefore, it can be used as a lubricant and has become an ideal coating for the inner layer of easy-to-clean water pipes. Polytetrafluoroethylene is often processed into granules by granulation equipment.

[0003] At present, there are three main ways to convey granular materials: one is belt conveying; the second is pneumatic conveying, and the third is mechanical screw conveying. For the transportation of production materials, pneumatic conveying is generally used. The principle of pneumatic conveying is to generate a vacuum airflow under the action of the fan and the pressure pump, and push the material in the conveying pipe through the vacuum airflow. In the process of transporting particles, it is inevitable that the feeding speed of polytetrafluoroethylene particles will be too fast. At this time, the particles will gather from a small number to a large number, and polytetrafluoroethylene particle clusters will form in the conveying pipeline. At this time, the polytetrafluoroethylene particle clusters will cause pipeline blockage. When dealing with the blockage, it is generally necessary to manually dismantle the pipeline and manually dredge it, which is time-consuming and labor-intensive and very inconvenient.
