[0002] Graphite has excellent properties and is widely used in machinery, nuclear energy, aerospace and other industries. With the rapid development of modern science and technology and industry, the application field of graphite is still expanding, and the demand for graphite products will continue to grow. Graphite is a machinable non-metallic material. It is easy to crack or break during the processing process. At the same time, a large amount of graphite dust will be generated. It is not only easy to pollute the working environment near the operating table, but also harmful to the health of the machine operator. Therefore, when producing and processing graphite, a vacuum cleaning device is usually used to suck the generated graphite dust into the cleaning device through a fan and a vacuum pipe.

[0003] Existing related dust collection and cleaning devices usually do not have a backflow prevention function. When the fan is turned off, some dust may flow back and leak out, which will be spread into the processing environment again, causing the air quality to deteriorate and having a negative impact on the health of workers. The use effect is relatively general. Therefore, those skilled in the art provide a graphite production machine tool cleaning device with an anti-backflow function to solve the problems raised in the above background technology.
