[0012] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0013] As Figure 1 shown, the present utility model provides an oil and gas cylinder assembly, including a main body 1 of the oil and gas cylinder. An oil and gas mixing inlet is provided on the side wall of the upper part of the main body 1 of the oil and gas cylinder. An oil and gas mixing pipe 2 is provided on the oil and gas mixing inlet. An outlet is provided on the top of the main body 1 of the oil and gas cylinder. An outlet elbow 3 is provided on the outlet. The outlet elbow 3 is connected with an external fine separator 4. A hot oil outlet is provided on the side wall of the lower part of the main body 1 of the oil and gas cylinder. A hot oil pipe 5 is provided on the hot oil outlet. The hot oil pipe 5 is connected with an oil inlet of a heat exchanger 6. An oil filter bracket 7 staggered from the oil and gas mixing inlet is further provided on the side wall of the upper part of the main body 1 of the oil and gas cylinder. An oil filter 8 is fixed on the oil filter bracket 7. An inlet of the oil filter 8 is connected with an oil outlet of the heat exchanger 6 through a cold oil pipe 9. A main engine return oil pipe 10 is provided at an outlet of the oil filter 8.

[0014] When the utility model is in use, the oil-gas mixture discharged by the air compressor enters the main body 1 of the oil-gas cylinder through the oil-gas mixing pipe 2. The main body 1 of the oil-gas cylinder conducts preliminary separation on the oil-gas mixture. Most of the oil medium is separated and stays in the main body 1 of the oil-gas cylinder. The separated gas enters the external fine separator 4 through the outlet elbow 3 for secondary separation, further reducing the oil content in the gas. The external fine separator 4 is provided with an air outlet and an oil drain port. The air outlet is connected to the cooler through an air pipe. After the gas enters the cooler through the air outlet and the air pipe for cooling, it is finally input into the air supply system. The oil drain port is used to discharge the oil medium in the external fine separator. The oil medium at the bottom of the main body 1 of the oil-gas cylinder enters the heat exchanger 6 through the hot oil pipe 5 for heat exchange. After the oil medium is cooled, it enters the oil filter 8 through the cold oil pipe 9 for filtration, and finally supplies oil to the air compressor through the main engine return oil pipe 10. The utility model adopts an external fine separator, which is convenient for maintenance. The external fine separator 4 of the utility model is fixed to the main body 1 of the oil-gas cylinder through the outlet elbow 3. The oil filter 8 is fixed to the main body 1 of the oil-gas cylinder through the oil filter bracket 7. Multiple components are integrated into one body, which is convenient for assembly and occupies a small space.

[0015] Preferably, a safety port is provided at the top of the main body 1 of the oil-gas cylinder. A safety valve 11 is provided on the safety port. When the gas pressure in the main body 1 of the oil-gas cylinder exceeds the set value, it can be discharged through the safety valve 11, making it safer to use. A sewage discharge port and an oil level gauge 12 are provided on the side wall at the bottom of the main body 1 of the oil-gas cylinder. A sewage discharge valve 13 is provided on the sewage discharge port. Opening the sewage discharge valve 13 can discharge the oil stain. The oil level gauge 12 can display the height of the oil medium in the main body 1 of the oil-gas cylinder. A fuel filling port is provided on the side wall in the middle of the main body 1 of the oil-gas cylinder. A plug 14 is provided on the fuel filling port. Usually, the plug 14 blocks the fuel filling port. When the oil medium in the main body 1 of the oil-gas cylinder is lower than the set value, the plug 14 can be opened, and the oil medium can be injected into the main body 1 of the oil-gas cylinder through the fuel filling port.

[0016] Preferably, the oil filter bracket 7 is L-shaped. The shape of the vertical section of the oil filter bracket 7 is adapted to the outer wall of the main body 1 of the oil-gas cylinder, and the vertical section of the oil filter bracket 7 is welded to the outer wall of the main body 1 of the oil-gas cylinder. A first fixing hole is provided at the top of the oil filter 8. A second fixing hole 15 opposite to the first fixing hole is provided on the horizontal section of the oil filter bracket 7. After the screw passes through the second fixing hole 15, it is fixed in the first fixing hole. The structure is simple and the assembly is convenient. The head of the oil filter 8 is arranged upward, and the filtering effect is good.

[0017] Preferably, the outlet elbow 3 is welded to the top of the main body 1 of the oil-gas cylinder. A support plate 16 is provided between the main body 1 of the oil-gas cylinder and the outlet elbow 3. The two ends of the support plate 16 are respectively welded to the main body 1 of the oil-gas cylinder and the outlet elbow 3. The support plate 16 is used to reinforce the outlet elbow 3 and play a supporting role for the external fine separator 4. The structure is simple and reliable.
