Embodiment
As shown in Fig. 1,2,3,4,5：Oil eliminator of the present utility model suitable for screw refrigeration unit, including cylinder 1,
Left end socket 2, right end socket 3, air inlet pipe group 4, escape pipe group 5, the first hydraulic barrier 6, the second hydraulic barrier 7, the 3rd hydraulic barrier
8th, the 4th hydraulic barrier 9, the first screen pack 10, the second screen pack 11, the first oil baffle 12, the second oil baffle 13, third gear oil
The grade of plate 14 part.Air inlet pipe group 4 and escape pipe group 5 are separately positioned on the two ends of end socket 2 and 3, and air inlet pipe group 4 is put in before shell portion
End, four square side openings 16 or circular duct are opened from orthogonal both direction, and the gas outlet of air inlet pipe group 4 utilizes termination
Baffle plate 15 stops；The entrance of escape pipe group 5 for upward, medial surface of the mouth of pipe just to cylinder 1, the 4th deflection plate 9 is provided with before entrance,
The base of 4th deflection plate 9 is less than the entrance of escape pipe group 5, i.e., height is bigger compared with elbow and the distance between the madial wall of cylinder 1.
Oil eliminator intracavity bottom sets the first oil baffle 12, the second oil baffle 13, the third gear oiled-plate method 14 of the open and clear mouth in periphery, and gap can
Using the form such as semicircle, square, triangle.Set in oil eliminator using staggered hydraulic barrier, double-stage filtering net and centre
There is the structure of baffle plate, i.e., the one end of the first hydraulic barrier 6 is fixed on the top of the first oil baffle 12, the other end and cylinder in staggered baffle plate
Gap is left between the inwall of body 1；The one end of second hydraulic barrier 7 is fixedly connected with the inwall of cylinder 1, the other end and the inwall of cylinder 1 it
Between leave gap.In the middle of double-stage filtering net, i.e. the 3rd hydraulic barrier 8 is set between first screen pack 10 and the second screen pack 11,
Positional structure is identical with the second hydraulic barrier 7 in staggered baffle plate.
The refrigerant gas with refrigerator oil is set to horizontally enter into after end socket during the oil device work of this structure, in baffle plate
The lower counter motion of effect is met with forward stream body phase, and flow direction deflects, air-flow will with horizontal airintake direction into more than 90 °
The direction at angle is flowed out from square or circular side holes road, is flow to end socket inwall and is collided.
Gas can be circulated in flow process it is smooth, be avoided that again band liquid.
The course of work of the present utility model is：Refrigerant gas with refrigerator oil is after air inlet pipe group from four sides
To the left inner chamber of end socket 2 of entrance, and collided with the left wall of end socket 2, realize and separate for the first time；Due to the change of airintake direction,
Disturbance of the refrigerant gas with refrigerator oil in cylinder 1 is more violent, effect of the larger oil droplet of particle diameter in centrifugal force
Issue estranged from the staggered each hydraulic barrier of airflow passes, constantly collides with baffle plate afterwards, and the larger oil droplet of particle diameter is because used
Property and stickiness effect be gathered on the wall of baffle plate after flow to cylinder body bottom, realize second and separate, so far, the larger oil of particle diameter
Drop is separated substantially；After airflow passes double-stage filtering net and middle baffle plate, the less oil droplet of particle diameter realizes the 3rd by silk screen refined filtration
Secondary separation；Set baffle plate to avoid oil-containing gases from being expelled directly out before the entrance of escape pipe group, realize the 4th separation.It is separated
Machine oil influent bag, come back in compressor, it is ensured that the normal operation of compressor.
The oil eliminator of the present invention is by designing oil separator structure, using entering for the surrounding open-celled structure with baffle plate
The structures such as tracheae, staggered hydraulic barrier, double-stage filtering net and the preposition baffle plate of middle baffle plate, venting conduit inlet, reinforcing oil gas point
From effect, to reduce the oil content in exhaust as far as possible, it is to avoid machine oil enters condenser and evaporator, and then improves condenser and steaming
The heat transfer efficiency of device is sent out, and effectively can prevent compressor from the risk of insufficient lubrication occurring because of oil starvation.
