[0015] FIG2 is a diagram showing the internal structure of the integrated refrigerant oil-gas separation device of the present invention. DETAILED DESCRIPTION

[0016] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0017] The present invention discloses an integrated refrigerant oil-gas separation device, as shown in Figures 1 to 2, which includes a base 1 and a support 2, the support 2 is fixed above the base 1, and a first separator 3, a second separator 4 and a sleeve 5 are fixed between the base 1 and the support 2. The first separator 3 is used to separate the semi-gas and semi-liquid refrigerant injected therein into refrigerant and refrigeration oil, the input end of the second separator 4 is connected to the output end of the first separator 3, and the second separator 4 is used to separate the compressor lubricating oil from the refrigerant output by the first separator 3. The sleeve 5 is sleeved on the outside of the first separator 3 and a refrigerant accommodating space 6 is formed between the two. The refrigerant accommodating space 6 is connected to the output end of the second separator 4, and the high-pressure gaseous refrigerant output by the second separator 4 is injected into the refrigerant accommodating space 6 and performs heat exchange with the refrigerant in the first separator 3.

[0018] In the above structure, the support 2 and the base 1 are fixed to the upper and lower ends of the first separator 3, the second separator 4 and the sleeve 5, the second separator 4 and the sleeve 5 are arranged side by side, the first separator 3 is built into the sleeve 5, and the refrigerant holding space 6 is formed between the two. During operation, the vehicle-borne high-pressure and low-temperature liquid semi-gas and semi-liquid refrigerant is injected into the first separator 3 under the drive of the compressor, and the first separator 3 is used to separate the semi-gas and semi-liquid refrigerant into refrigerant and refrigeration oil. The refrigerant after preliminary separation is then injected into the second separator 4, and the second separator 4 is used to separate the compressor lubricating oil from the refrigerant. At this time, the refrigerant discharged from the second separator 4 is a high-pressure and high-temperature gaseous refrigerant. After it is injected into the refrigerant holding space 6, because the refrigerant holding space 6 surrounds the outside of the first separator 3, it helps to heat up the first separator 3, thereby improving the separation efficiency of the refrigeration oil / compressor oil and the refrigerant, and better meeting the application requirements.

[0019] As a preferred embodiment, the first separator 3, the second separator 4 and the sleeve 5 are all arranged vertically, that is, the first separator 3, the second separator 4 and the sleeve 5 are arranged vertically and side by side.

[0020] In order to allow the refrigerant accommodating space 6 to fully surround the first separator 3, in this embodiment, the sleeve 5 is arranged concentrically with the first separator 3. Based on the above structure, the heat exchange efficiency between the refrigerant accommodating space 6 and the medium in the first separator 3 is improved.

[0021] In this embodiment, the refrigerant holding space 6 serves as a heat supplement mechanism, and the hot refrigerant in the space transfers heat to the low-temperature refrigerant in the first separator 3. After the first separator 3 is heated up, it is beneficial to improve the oil and gas separation efficiency therein, and at the same time, the refrigerant in the refrigerant holding space 6 is cooled, which is beneficial for the liquefied refrigerant to flow to the storage tank.

[0022] To improve the structural stability of the integrated refrigerant oil-gas separation device, referring to Figures 1 and 2 , in this embodiment, the base 1 and the support 2 are fixedly connected via a plurality of support columns 7. Specifically, there are six support columns 7 , which are arranged in two rows on both sides of the first separator 3 , the second separator 4 , and the sleeve 5 .

[0023] In this embodiment, the second separator 4 and the refrigerant storage space 6 are in a one-way communication relationship, thereby preventing the backflow of the gaseous refrigerant. Specifically, this embodiment includes a one-way valve 8, which is connected between the second separator 4 and the refrigerant storage space 6. The one-way valve 8 is fixed to the top of the support 2.

[0024] As a preferred embodiment, the first separator 3, the second separator 4 and the sleeve 5 are all cylindrical. In practical applications, the first separator 3, the second separator 4 and the sleeve 5 can also be components of other shapes, such as a cuboid, a polygon, etc.

[0025] During the operation of the present invention, the vehicle-mounted high-pressure, low-temperature liquid semi-gas, semi-liquid refrigerant enters the first separator 3 through a pipeline under the drive of the compressor. The device separates the refrigerant and the refrigeration oil. The refrigerant becomes a high-pressure, high-temperature gas after passing through the compressor. When passing through the second separator 4, the refrigerant and the compressor lubricating oil are separated. At the same time, the refrigerant flows to the refrigerant accommodating space 6 through a one-way valve. In the refrigerant accommodating space 6, the hot refrigerant conducts heat to the low-temperature refrigerant in the first separator 3. In the process of heating up the first separator 3, it is beneficial to improve the oil and gas separation efficiency of the first separator. At the same time, the refrigerant in the refrigerant accommodating space 6 is cooled, which is beneficial to the liquefied refrigerant flowing to the storage tank.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
