Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a vacuum pump with filtering and separating functions. Background Art

[0002] A vacuum pump utilizes mechanical methods to extract gas molecules from a container to maintain a certain vacuum requirement. Since the industries and departments in which vacuum is used involve a very wide range of work, no single pump can be suitable for all work standards and requirements. The only option is to select a corresponding vacuum pump based on different working pressure ranges and different working requirements. With the continuous development and innovation of people's scientific and technological level, vacuum pumps are now divided into many types, including water ring pumps, reciprocating pumps, rotary vane pumps, and dry screw vacuum pumps. The overall internal structure of the vacuum pump can be divided into vertical and horizontal structures.

[0003] The existing vacuum pump only has a filter device at the exhaust port, and does not have the function of separating the oil mist particles from the gas. At the same time, long-term exhaust and filtering will cause the oil mist particles to adhere to the inside of the filter device, which may cause solidification, reduce the quality of the filtered gas or cause it to no longer be discharged directly.

The inner wall of the limit block 18 is threadedly connected to the outer surface of the limit pipe 19, and the inner wall of the limit block 18 is threadedly connected to the outer surface of the oil outlet 17.

[0033] When the staff needs to use the vacuum pump, they first connect the vacuum pump body 1 to the equipment, then start the vacuum pump body 1, and the vacuum pump starts to evacuate the inside of the equipment. The evacuated gas enters the inside of the housing 4 from the connecting pipe 2, and then passes through the screen 15 to block a certain amount of dust. Then, the filter element 13 filters the gas and intercepts the oil mist particles. The filtered gas is discharged from the exhaust hole 5, and the oil mist particles flow into the guide groove 1 14 into the guide groove 2 16, and then flow into the limit pipe 19 from the oil outlet 17 along the guide groove 2 16, and finally flow into the oil storage box 21, realizing the oil The mist particles and gas are filtered and separated, and the outer shell 4 can be rotated at the same time to disconnect the connecting pipe 2 and the limit ring 3, and then the outer shell 4 can be removed from the upper surface of the vacuum pump body 1 for replacement, and the limit block 18 can be rotated to disconnect the inner wall of the limit block 18 from the outer surface of the limit tube 19 until the limit block 18 is sleeved on the outer surface of the oil outlet 17, so that the limit tube 19 and the oil outlet 17 can be disconnected, and the oil storage box 21 can be replaced.
