At present, an air inlet pipe of a conventional oil separator is directly connected with an air outlet of a compressor, the air outlet of the compressor is high-pressure gaseous refrigerant, and after entering the oil separator, vortex is easily generated at the bottom of the oil separator, so that the high-temperature high-pressure gaseous refrigerant enters an oil return pipe, and the normal oil return is adversely affected. Therefore, improvements are needed to improve the stability of the oil return.

Disclosure of Invention

The invention aims to provide an oil content structure capable of stably returning oil, which can effectively avoid vortex from being formed at the bottom of the oil content structure, improve the stability of the oil return and ensure the normal operation of a compressor.

The technical scheme of the invention is as follows:

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 invention has the beneficial effects that:

the oil separator has the advantages of reasonable design, simple structure, convenience in production and installation, capability of effectively avoiding vortex from being formed at the bottom of the oil separation structure, improvement of oil return stability and guarantee of normal operation of the compressor.

Detailed Description

The invention is further described below with reference to the figures 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.

According to the invention, the oil return port is properly covered by the baffle plate, so that disturbance of accumulated oil in the lower end cover caused by rotation of gaseous refrigerant in the shell is effectively avoided, vortex formation is prevented, gaseous refrigerant is reduced from entering the oil return pipe, lubricating oil is ensured to fully flow back to the compressor, the stability of oil return is improved, and the normal operation of the compressor is ensured.

The parts not involved in the present invention are the same as or can be implemented using the prior art.
