Abstract
The utility model provides an oil-gas separator for an oil injection screw air compressor. The oil-gas separator comprises a cylindrical housing (1) and an oil-gas separating inner core (2), wherein the oil-gas separating inner core (2) comprises a main body (201) and a back cover (203), the upper part of the main body is open and is provided with an air hole (202), the back cover (203) is arranged at the bottom of the main body (201), the oil-gas separating inner core (2) is vertically arranged in the housing (1), and the outer surface of the upper part of the oil-gas separating inner core (2) is fixedly connected with the inner wall of the housing (1). The oil-gas separator is characterized in that the longitudinal section of the main body (201) is shaped like a trapezoid with a small upper part and a big lower part, and an oil-gas mixture inlet (101) is formed in the housing at the lower part of the oil-gas separating inner core (2). The oil-gas separator is simple in structure and good in separating effect; and the smaller oil-gas separator is adopted for achieving the same separating effect under the condition of the same gas quantity, and thus the equipment cost is saved.
Description
Technical field
The utility model relates to a kind of deaerator, is specifically related to the deaerator for exhaust end base of oil injection threaded bolt air press, particularly the Oil-gas Separation inner core in the deaerator.
Background technique
Screw rod air press is a kind of important equipment, and purposes is very extensive.
In exhaust end base of oil injection threaded bolt compressor operation working procedure, oily and compressed gas has formed gas mixture, be discharged in the deaerator of Compressor Group, in deaerator, carry out oil, gas separation, air after the separation is discharged in user's pipe network, and the oil that separates reenters after supercooling and forms oil circulation in the compressor.And the less amount of lubrication oil that can not separate consumes with the air discharge.Deaerator has Oil-gas Separation and two effects of buffering, and in order to reduce the oil content and the lubricant oil that recycles in the unit in the unit exhaust, then must utilize deaerator that lubricant oil is separated from gas effectively.
Along with the attention that compressed air quality day by day is subjected to, in order to reduce the oil content in the pressurized air, deaerator plays a part very crucial, and the Oil-gas Separation inner core is the core component of deaerator, and its performance has directly influenced compressed-air actuated quality.
At present, the conventional exhaust end base of oil injection threaded bolt air press deaerator that is used for comprises: shell and the Oil-gas Separation inner core that is arranged on shell, and described Oil-gas Separation core shape is generally cylindrical body, diameter up and down is identical, the existing defective of the Oil-gas Separation inner core of this structure is, when the separated gas mixture of needs enters cavity between shell and the Oil-gas Separation inner core from the entrance that is arranged on outer casing underpart, gas mixture is in described cavity, reason owing to flow resistance, distribution up and down is inhomogeneous, on Oil-gas Separation inner core top, almost there is not gas mixture, cause the working efficiency of Oil-gas Separation inner core to reduce greatly.
The model utility content
The purpose of this utility model provides a kind of for exhaust end base of oil injection threaded bolt air press deaerator, to overcome the above-mentioned defective that prior art exists.
Described in the utility model for exhaust end base of oil injection threaded bolt air press deaerator, comprise columned shell and Oil-gas Separation inner core, described Oil-gas Separation inner core comprises top main body and back cover open, that be provided with air hole, described back cover is arranged on the bottom of main body, described Oil-gas Separation inner core is vertically set in the shell, and the outer surface on its top is fixedlyed connected with the inwall of described shell;
It is characterized in that being shaped as of the longitudinal section of described main body is up-small and down-big trapezoidal, the gas mixture entrance is arranged on the shell of described Oil-gas Separation inner core bottom.
The beneficial effects of the utility model are that simple in structure, separating effect is better, under identical tolerance, reaches identical separating effect, can adopt less deaerator, has saved equipment cost.

Embodiment
Referring to Fig. 1 and Fig. 2, described in the utility model for exhaust end base of oil injection threaded bolt air press deaerator, comprise columned shell 1 and Oil-gas Separation inner core 2, described Oil-gas Separation inner core 2 comprise top open, be provided with air hole 202 main bodys 201 and back cover 203, described back cover 203 is arranged on the bottom of main body 201, described Oil-gas Separation inner core 2 is vertically set in the shell 1, and the outer surface on its top is fixedlyed connected with the inwall of described shell 1;
Described main body 201 can adopt fiberglass braided forming;
It is characterized in that being shaped as of the longitudinal section of described main body 201 is up-small and down-big trapezoidal, gas mixture entrance 101 is arranged on the shell of bottom of described Oil-gas Separation inner core 2;
Preferably, the spacing L1 between described main body 201 bottoms and shell 1 inwall be between described main body 201 tops and shell 1 inwall spacing L2 60%～80%, that is: L1=L2 * 60%～80%;
Further, in the cavity 3 between described Oil-gas Separation inner core 2 and shell 1, be provided with the deflection plate 4 that is vertically fixed on outer casing inner wall, the gas mixture flow velocity is reduced, rely on inertial force, make oil droplet accelerate sedimentation;
Further, describedly also comprise oil droplet collector 5 for exhaust end base of oil injection threaded bolt air press deaerator, described oil droplet collector 5 is arranged on the bottom of shell 1, and is connected with shell, and oil droplet collector 5 is provided with oil outlet 8;
Further, describedly also comprise safety valve 6 for exhaust end base of oil injection threaded bolt air press deaerator, described safety valve 6 is arranged on the shell, and is connected with cavity between shell 1 and the Oil-gas Separation inner core 2;
Further, describedly also comprise oil pick-up tube 7 for exhaust end base of oil injection threaded bolt air press deaerator, described back cover 203 is umbrella shape, the umbrella top downwards, an end of described oil pick-up tube 7 is positioned at back cover 203 places, the other end extends upwardly to outside the shell;
Working principle of the present utility model is such:
Carry the gas mixture that the compressor host of big and small oil droplet comes out secretly, entered in the cavity 3 between Oil-gas Separation inner core 2 and the shell 1 by gas mixture entrance 101, from bottom to top flow, because the channel cross-section on cavity 3 tops is greater than the cross section of bottom, therefore, the resistance on cavity 3 tops is less than the resistance of bottom, and gas mixture is in described cavity 3, better distribution can be accessed, the efficient that gas separates inner core 2 can be improved.
