Abstract
The utility model discloses an oil spraying preventing device of a vacuum pump. The device comprises a pipe body with two open ends, one end of the pipe body is an exhaust port, the other end of the pipe body is an oil and gas guiding port, a filter screen pipe used for adsorbing lubricating oil is arranged in the pipe body, one end of the filter screen pipe is closed, and the other end of the filter screen pipe is an opening which faces towards the oil and gas guiding port. The oil spraying preventing device disclosed by the utility model can be used for avoiding the phenomenon that the exhaust port of the vacuum pump sprays the lubricating oil when the vacuum pump pumping the vacuum, and saving the cost.
Description
Technical field
The utility model relates to the anti-oil spout device of a kind of vacuum pump, belongs to the vacuum pump technology field.
Background technique
At present, cryogenic liquid tank, low temperature tanker equal vacuum equipment generally adopts rotary-vane vaccum pump to carry out product and vacuumizes, work as cryogenic liquid tank, when low temperature tanker equal vacuum equipment chuck does not have vacuum or micro-malleation is arranged, with rotary-vane vaccum pump chuck is vacuumized, if vacuumize valve in bigger opening state, having many vacuum pump lubricant oil sprays from the vacuum pump relief opening with the gas of extracting out, cause the pollution of environment and the waste of vacuum pump lubricant oil, therefore, when practical operation, often need operator slowly to open and vacuumize valve, increased difficulty and the waste of manpower resource of operation.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, and a kind of phenomenon of vacuum pump relief opening lubricating oil spraying when avoiding vacuum pump to vacuumize is provided, and saves the anti-oil spout device of vacuum pump of cost.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of vacuum pump is prevented the oil spout device, the body that comprises both ends open, one end of body is relief opening, an other end of body is the oil gas introducing port, be provided with the filter screen pipe of adsorpting lubrication oil in the body, and an end of filter screen pipe is closed shape, the other end is opening and facing to the oil gas introducing port.
Further, filter screen pipe retaining ring is arranged fixedly on the inwall of described body, the outer wall of described filter screen pipe is fixed on the filter screen pipe retaining ring.
Further, be stamped dust-proof cover on the relief opening of described body.
Further, described body has threaded joints at the inwall at oil gas introducing port place.
After having adopted technique scheme, after vacuum pump is installed anti-oil spout device, lubricant oil with the gas bleeding ejection is blocked in filter screen pipe inside by the filter screen pipe, and flow into again in the vacuum pump casing along the filter screen tube wall, the gas of extracting out is discharged from the aperture on the filter screen pipe, plays the effect of Oil-gas Separation; Dust-proof cover has prevented that external dust from entering the relief opening of body; The oil gas introducing port that threaded joints is convenient to body connects the vacuum pump relief opening of going up vacuum pump.
Description of drawings
Fig. 1 is the structure sectional view of the anti-oil spout device of vacuum pump of the present utility model.
Embodiment
Content of the present utility model is easier to be expressly understood in order to make, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below,
As shown in Figure 1, a kind of vacuum pump is prevented the oil spout device, the body 3 that comprises both ends open, one end of body 3 is relief opening 3-1, an other end of body 3 is oil gas introducing port 3-2, be provided with the filter screen pipe 4 of adsorpting lubrication oil in the body 3, and an end of filter screen pipe 4 is closed shape, the other end is opening and facing to oil gas introducing port 3-2.
As shown in Figure 1, filter screen pipe retaining ring 5 is arranged fixedly on the inwall of body 3, the outer wall of filter screen pipe 4 is fixed on the filter screen pipe retaining ring 5.
In order to prevent that external dust from entering the relief opening of body 3, as shown in Figure 1, be stamped dust-proof cover 1 on the relief opening 3-1 of body 3.
For the ease of the vacuum pump relief opening of vacuum pump in the oil gas introducing port 3-2 connection of body 3, as shown in Figure 1, body 3 has threaded joints 3-2-1 at the inwall at oil gas introducing port 3-2 place.
After vacuum pump is installed anti-oil spout device, lubricant oil with the gas bleeding ejection is blocked in filter screen pipe 4 inside by filter screen pipe 4, and flow into again in the vacuum pump casing along filter screen pipe 4 tube walls, the gas of extraction is discharged from the aperture on the filter screen pipe 4, plays the effect of Oil-gas Separation.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
