Description

Technical Field

[0001] The utility model relates to the technical field of refrigerant recovery and filling machines, in particular to an oil-gas separator. Background Art

[0002] The refrigerant recovery and filling machine is a machine that recovers, purifies, stores and refills the refrigerant of the automobile air-conditioning system into the automobile air-conditioning system, saving refrigerant raw materials and avoiding the discharge of refrigerant into the atmosphere to pollute the environment. At present, the working principle of the refrigerant recovery and filling machine is to recover the refrigerant of the automobile air-conditioning system into the machine through a compressor, separate the refrigerant and refrigeration oil through an oil-gas separator in the machine, filter out water vapor through a drying filter, and reduce the pressure of the purified refrigerant through a condenser and enter the refrigerant tank of the equipment for storage. The refrigerant recovery and filling machine for the automobile air-conditioning system can also vacuum and purify the automobile air-conditioning system, and when the automobile air-conditioning system is vacuumed, the pure refrigerant stored in the refrigerant tank of the machine and the refrigeration oil in the equipment oil bottle are added to the automobile air-conditioning system through the pressure difference.

During the oil-gas separation process, part of the refrigeration oil vaporized by the high temperature will still be mixed in the refrigerant and leave the oil-gas separator with the refrigerant, resulting in incomplete separation of the refrigerant and refrigeration oil and poor separation quality.

The gas outlet 8 and the liquid outlet 9 are arranged at the upper and lower ends of the oil and gas separation tank 1, the water inlet 6 and the water outlet 7 are located above the partition 2, and the water inlet 6 is vertically located at the top of the oil and gas separation tank 1, and the water outlet 7 is horizontally located above the partition 2, the gas outlet 8 and the liquid outlet 9 are located at the upper and lower ends of the gas output pipe 3, and a gap is left between the liquid outlet 9 and the lower end of the gas output pipe 3, and a liquid collecting funnel 10 is fixedly arranged on the bottom of the oil and gas separation tank 1, and the mouth of the liquid collecting funnel 10 is directly opposite to the liquid outlet 9.

[0023] like Figure 2 As shown, the oil-gas cooling pipe 4 is in a spiral tube shape, and the rotation direction is consistent with the spiral blade 5. A plurality of airflow baffles 3a are fixedly arranged inside the gas output pipe 3, and the adjacent airflow baffles 3a are arranged in an up-down staggered manner, and the airflow baffles 3a are located above the partition 2. By adopting the above-mentioned spiral tube-shaped oil-gas cooling pipe 4 and airflow baffles 3a, the passage time of the oil-gas mixture can be effectively extended, thereby further improving the cooling effect of the oil-gas mixture. At the same time, the spiral tube-shaped oil-gas cooling pipe 4 can also guide the oil-gas mixture to rotate in the same direction as the spiral blade 5, thereby increasing the mileage of the oil-gas mixture's rotational movement and further improving the oil-gas separation quality.

[0024] like Figure 2As shown, a mesh filter cartridge 11 is movably sleeved at the lower end of the gas output pipe 3, and the lower end of the filter cartridge 11 contacts the funnel neck of the liquid collecting funnel 10; the liquid collecting funnel 10 is provided with a right-angle groove 10a at its funnel neck to support and position the lower end of the filter cartridge 11; an air flow baffle 11a is fixedly arranged in the middle of the filter cartridge 11, and the air flow baffle is in a conical shape.

[0027] The working principle of this embodiment:

[0028] When the oil-gas mixture of refrigerating oil and refrigerant enters the oil-gas separator, it will first enter the oil-gas cooling pipe 4. Since the water inlet 6 and the water outlet 7 on the oil-gas separation tank 1 are constantly circulating cooling water into the tank space above the partition 2, the oil-gas mixture passing through the oil-gas cooling pipe 4 will exchange heat with the cooling water and reduce its own temperature; then the oil-gas mixture coming out of the oil-gas cooling pipe 4 will enter the tank space below the partition 2, and under the guidance of the spiral blades on the side of the gas output pipe 3, it will flow in a spiral direction below the partition 2; then the heavier refrigerating oil in the oil-gas mixture will be thrown onto the tank wall of the oil-gas separation tank 1 under inertia, and will be collected in the lower liquid collecting funnel 10 and flow out of the liquid outlet 9; finally, the lighter refrigerant in the oil-gas mixture will enter from the lower end of the gas output pipe 3, and flow out from the gas outlet 8 above the oil-gas separation tank 1 along its internal channel. Among them, since the upper part of the gas output pipe 3 is located in the tank space on the partition 2, and multiple air flow baffles are arranged inside, the vaporized refrigeration oil still remaining in the refrigerant is cooled again when passing through this section, and finally liquefies and falls back to the bottom of the tank, thereby fully ensuring the separation quality of the oil-gas separator.
