The lubricating oil to be processed is stored in the infusion set, and the lubricating oil is conveniently discharged from the infusion tube and the infusion plate from the liquid outlet to the preparation tank through the infusion set. The first-level filtration can be achieved through the filter net, and the lubricating oil is conveniently processed through the preparation tank. The waste gas discharged during the preparation process is discharged from the exhaust hole and discharged into the filter tank through the exhaust pipe. The filter tank stores the filtrate, and the waste gas is filtered and processed through the filtrate, and then discharged from the outlet pipe. In the process of implementing this scheme, it is found that there are the following problems in the prior art, which have not been well solved: the above-mentioned device discharges the waste gas of the lubricating oil into the filter tank through the exhaust hole through the filter device such as the filtrate, but after filtering the waste gas of the lubricating oil for a long time, the filter material such as the filtrate is difficult to replace, which leads to poor filtering effect of the waste gas of the lubricating oil.
