an oil content structure capable of stably returning oil comprises a shell, an air inlet pipe, an air outlet pipe and an oil return pipe, wherein the shell is a cylindrical barrel, and an upper end cover and a lower end cover of the shell are both flat-bottomed bowl-shaped; the air outlet pipe is arranged on the upper end cover in a penetrating way; the air inlet pipe is arranged on the side wall of the upper part of the shell in a penetrating way; the oil return pipe is connected to the lower end cover and is communicated with the lower end cover; a transverse baffle is arranged at the lower part in the shell; the baffle is disc-shaped, is provided with a plurality of through holes, and the periphery of the baffle is connected with the inner wall of the shell.

Furthermore, a plurality of notches are formed in the edge of the baffle.

Further, the diameter of the through hole is not less than 2 mm; the sum of the areas of all the through holes is 40-70% of the area of the baffle.

Further, the included angle between the baffle and the radial plane of the shell is 0-80 degrees.

Furthermore, the distance between the baffle and the bottom surface of the lower end cover is 2-20 cm.

The utility model has the advantages that:

the utility model relates to a rationally, simple structure, the production and the installation of being convenient for to can effectively avoid forming the swirl in oil content structure bottom, improve the stability of oil return, ensure the normal operating of compressor.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2.

An oil content structure capable of stably returning oil comprises a shell 3, an air inlet pipe 6, an air outlet pipe 5 and an oil return pipe 7. The shell 1 is a cylindrical barrel, and the upper end cover 4 and the lower end cover 1 are both flat-bottomed bowl-shaped. The outlet pipe 5 is installed on the upper end cover 4 in a penetrating manner, so that the inlet end of the outlet pipe extends into the lower part of the shell 3, and the separated gaseous refrigerant is fully discharged. The air inlet pipe 6 is arranged on the side wall of the upper part of the shell 3 in a penetrating way, and the inlet end of the air inlet pipe extends into the shell 3 along the radial direction of the shell 3, so that the gas refrigerant mixed with lubricating oil can conveniently enter the shell 3 to form rotation, and oil and gas can be separated. The oil return pipe 7 is connected to the lower end cover 1 and communicated with the lower end cover 1, so that lubricating oil collected in the lower end cover 1 can flow out through the oil return pipe 7. The oil return pipe 7 is connected to the suction port of the compressor to allow the separated lubricant oil to flow back to the compressor. A transverse baffle 2 is arranged at the lower part in the shell 3; this baffle 2 is discoid, is equipped with a plurality of through-holes 8 on it, its periphery with 3 inner walls of casing link to each other, can be right oil return opening on the lower end cover 1 shelters from, avoids near the long-pending oil of oil return opening to form the swirl and makes gaseous state refrigerant and oil flow into oil return pipe 7 together, influences the oil return effect.

The edge of the baffle 2 is provided with a plurality of gaps 9, so that separated lubricating oil can flow into the lower end cover 1 along the inner wall of the shell 3 more smoothly.

The diameter of the through holes 8 is not less than 2mm, and the sum of the areas of all the through holes 8 is 40-70% of the area of the baffle 2, so that the separated oil can be fully flowed into the lower end cover 1. All the through holes 8 are radially and uniformly distributed by taking the center of the baffle plate 2 as the center. And can be distributed in other shapes to ensure that the separated lubricating oil can smoothly pass through the baffle 2.

The baffle 2 with the contained angle between the radial plane of casing 3 is 0 to 80, can easy to assemble. The baffle 2 may be oval or other shape to ensure its perimeter to be attached to the inner wall of the housing 3 when it is mounted at an angle.

The baffle 2 can be directly welded on the inner wall of the shell 3, a plurality of mounting blocks can be arranged on the inner wall of the shell 3, and then the baffle 2 is welded on the mounting blocks, so that the installation operation is further facilitated.

The distance between the baffle 2 and the bottom surface of the lower end cover 1 is 2-20cm, so that sufficient space can be ensured in the lower end cover 1 to store lubricating oil. Meanwhile, the baffle 2 can be prevented from touching the inlet end of the gas outlet pipe 5 to influence the discharge effect of the gaseous refrigerant.

The utility model discloses a baffle suitably covers the oil return opening, has effectively avoided gaseous state refrigerant's rotation in the casing and has caused the disturbance to the long-pending oil in the lower end cover, prevents to form the swirl, reduces gaseous state refrigerant entering oil return pipe, ensures that lubricating oil fully flows back to the compressor, improves the stability of oil return, guarantees the normal operating of compressor.

The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
