Abstract
A vacuum pump exhaust port oil-filter silencer is installed on an exhaust port of a vacuum pump. A filter core is installed in a shell of the vacuum pump exhaust port oil-filter silencer, the top end of the shell is provided with an air outlet, the lower end of the shell is provided with an oil exhaust port, the upper end of the shell is provided with a horizontal beam, a silencing cover is designed in the middle of the horizontal beam, a fixing screw is installed in the middle of the silencing cover, the lower portion of the fixing screw is fixed at the top of the filter core, and the lower portion of the filter core is provided with an installation head fixed at the bottom of the shell and installed in the exhaust port of the vacuum pump. The filter core is composed of an outer wall, an inner wall and a filter layer, and the outer layer of the inner wall is wrapped by a filter layer. By adopting the technical scheme, and gas exhausted from the exhaust port of the vacuum pump is filtered by the filter core, and filtered engine oil backflows to the vacuum pump, thereby reducing consumption of the engine oil and pollution to the air caused by the discharged gas. The filter core and the shell can block noise so that the vacuum pump exhaust port oil-filter silencer can well eliminate working noise of the vacuum pump.
Description
Technical field
The utility model belongs to vacuum pump attachment technique field, relates to a kind of vacuum pump relief opening oil strain silencing apparatus.
Background technique
Vacuum pump is when vacuumizing; Relief opening can discharge big noise; And the machine oil in the pump is agitated and can goes out a lot of tiny bubbles, and tiny bubble can form the machine oil spittle, discharges from the relief opening of vacuum pump with the gas of extracting out; Cause the loss of vacuum pump machine oil, relief opening surrounding atmosphere is stained.
Technological scheme
The utility model is in the existing technology, and vacuum pump relief opening noise is big, the machine oil spittle can cause machine oil loss, air-polluting problem from the floss hole ejection, and a kind of vacuum pump relief opening oil strain silencing apparatus is provided, and its technological scheme is following:
A kind of vacuum pump relief opening oil strain silencing apparatus is installed in the relief opening of vacuum pump, in its shell filter core is installed; The top of shell has the air outlet, and the lower end is designed with oil drain out, and the upper end of shell is equipped with crossbeam; The crossbeam middle part is designed with the noise reduction lid, and set screw is equipped with at noise reduction lid middle part, and the bottom of set screw is fixed on the top of filter core; The bottom of filter core is designed with installation head, and installation head is fixed on the bottom of shell, and installation head is installed in the vacuum pump relief opening;
Filter core is made up of outer wall, inwall and filter layer; The upper design of outer wall has screw, and set screw is inserted in the screw, and top, side has outer pore; The installation head design is in the bottom of outer wall; Middle and lower part at inwall is designed with inner air vent, inwall have spill port bottom, the skin of inwall is enclosed with filter layer.
Adopt technique scheme, the gas from the vacuum pump relief opening is discharged receives the filtration of filter core, and the machine oil that filters out is back in the vacuum pump, has reduced the loss and exhausting air the staining air of machine oil; Because filter core and shell stop that to noise the utility model also has the effect of good elimination vacuum pump operational noise.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment: as shown in Figure 1, a kind of vacuum pump relief opening oil strain silencing apparatus is installed in the relief opening 2 of vacuum pump 1; In its shell 4 filter core is installed, the top of shell 4 has air outlet 10, and the lower end is designed with oil drain out 3; The upper end of shell 4 is equipped with crossbeam 8, and crossbeam 8 middle parts are designed with noise reduction lid 12, and noise reduction is covered 12 middle parts set screw 11 is housed; The bottom of set screw 11 is fixed on the top of filter core; The bottom of filter core is designed with installation head 16, and installation head 16 is fixed on the bottom of shell 4, and installation head 16 is installed in the vacuum pump relief opening 2; Filter core is made up of outer wall 5, inwall 7 and filter layer 6; The upper design of outer wall 5 has screw 9, and set screw 11 is inserted in the screw 9, and top, side has outer pore 13; Installation head 16 designs are in the bottom of outer wall 5; Be designed with inner air vent 14 in the middle and lower part of inwall 7, inwall 7 have spill port 15 bottom, the skin of inwall 7 is enclosed with filter layer 6.
