[0002] The Roots pump is the most commonly used dry pump. It contains two synchronously rotating bladed rotors in opposite directions. The gap between the rotors and the gap between the rotors and the pump chamber is typically tens to hundreds of microns. During operation, the rotors mesh to expel gas. In semiconductor production lines, the gases pumped are mostly chemical reaction gases, and the reaction products generate a large amount of dust, which can affect the normal operation of the dry pump. On the one hand, the high temperatures generated during operation cause the rotors to expand thermally. On the other hand, when large amounts of dust adhere to the rotors, they further reduce the gap between the rotors. In severe cases, they can cause the rotors to seize, which is the most common Roots pump failure in engineering. However, the Roots pump rotors do not have a dust collection function. In addition to adhering to the rotors, large amounts of dust can also accumulate in grooves and crevices within the pump chamber, requiring cleaning during regular disassembly and maintenance.

[0027] In this embodiment, the rotor body 1, the connecting hole 4 and the dust collecting mechanism 5 work together to make the device more convenient to use. The device is more stably connected to the rotor body 1 through the connecting hole 4.

A dust brush 64 is fixedly installed on the inner side of the collection box 63. When the collection box 63 is pulled out, the dust brush 64 can clean the dust connected to the bottom of the filter 62, making the device easier to clean. Example
