Further, in the safety oil tank with the catcher for the vacuum pump, the exhaust core comprises at least two reverse-cone-shaped buffer baffle plates which are arranged up and down, a plurality of air vents are formed in each buffer baffle plate on the surface of the plate, and the air vents on the two adjacent buffer baffle plates are staggered. In this structure, buffer baffle mainly plays the effect that prevents to splash and stop big oil drop direct discharge trap, and dislocation arrangement can realize the circuitous outflow of air current, increases the contact probability of oil drop and buffer baffle.
In the safety oil tank with the catcher for the vacuum pump, the shell comprises an upper shell and a lower shell which are connected through threads, and a sealing ring is arranged at the joint of the upper shell and the lower shell.
Further, in the safety oil tank with the catcher for the vacuum pump according to the present utility model, the outlet joint and the discharge hose are fastened by the clamping hoop.
The beneficial effects of the utility model are as follows:
the structure realizes the blocking or opening of the vent hole through the sliding of the sliding sleeve, has a unidirectional flow guiding function, prevents oil gas from backflushing back into the oil tank, and can discharge the oil gas to an open area far away from a workplace through a discharge hose by adding the discharge hose with enough length at the upper end of the catcher, thereby avoiding polluting the workplace; meanwhile, by newly adding the pressure relief safety valve, explosion risks caused by blockage of the discharge hose are avoided, and the use safety is improved.

Detailed Description
The utility model will now be further described with reference to the accompanying drawings:
referring to fig. 2-4, the embodiment provides a safety oil tank with a catcher for a vacuum pump, which comprises an oil tank body and a catcher, wherein the catcher comprises a shell 7, an exhaust core arranged in the shell 7 and an inlet joint 8 arranged at the lower end of the shell 7 and used for communicating an inner cavity of the oil tank body. The shell 7 comprises an upper shell 7a and a lower shell 7b which are in threaded connection, and a sealing ring 15 is arranged at the joint of the upper shell 7a and the lower shell 7 b. The lower end of the exhaust core is fixedly provided with a sliding sleeve 10, the peripheral wall of the sliding sleeve 10 is provided with a plurality of vent holes 10a, the sliding sleeve 10 can vertically slide and pass through the inlet joint 8, the inner wall of the inlet joint 8 is plugged or the vent holes 10a are opened by vertically sliding, and the shell 7 is internally provided with an elastic piece 11 which enables the sliding sleeve 10 to always have a downward movement trend; the elastic piece 11 is a spring which is abutted between the inner wall of the upper end of the shell 7 and the upper end of the exhaust core. The upper end of the shell 7 protrudes upwards and extends to form an outlet joint 12, a discharge hose 13 is sleeved outside the outlet joint 12, and the outlet joint 12 and the discharge hose 13 are fastened through a clamping hoop 14. The outer peripheral wall of the outlet joint 12 is provided with a plurality of bamboo-shaped convex teeth which are closely contacted with the inner wall of the discharge hose 13.
The structure changes the relative position of the vent hole 10a and the inner wall of the inlet joint 8 through the up-and-down sliding of the sliding sleeve 10, so that the vent hole 10a is plugged or opened, gas in the oil tank can be guided to flow out only in one direction, the reverse flow of oil gas is avoided, and the gas is discharged to an open area far away from a workplace through the discharge hose 13 with enough length connected to the catcher, so that the pollution to the workplace is avoided.
In this embodiment, a relief valve 16 is also mounted at the upper end of the tank. Since gas of a certain pressure generated when the vacuum pump is operated is accumulated in the tank body when the trap or the drain hose 13 is clogged, the pressure in the tank body is continuously increased, possibly reaching more than 1MPa, resulting in a risk of explosion of the tank. After the pressure relief safety valve is additionally arranged, when the pressure in the oil tank reaches a certain value, the pressure relief safety valve 16 can act, so that the pressure in the oil tank is rapidly reduced, and the working safety and reliability are improved.
