[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This pneumatic lubricating oil internal circulation component, by rotating the rotating column, causes the sealing ball to rotate, making the groove on the outer wall of the sealing ball parallel to the inlet pipe. At this time, the coolant inside the cooling plate can reach the inside of the inner cooling pipe through the inside of the inlet pipe. The water pump is started, and the water pump draws the cooling water inside the inner cooling pipe into the inside of the return pipe through the connecting pipe. It then flows back to the inside of the cooling plate through the return pipe, so that the coolant flows from the inside of the inner cooling pipe, dissipating heat from the middle of the lubricating oil. The coolant outside the cooling plate dissipates heat from the outside of the oil pipe, dissipating heat from both the inside and outside of the lubricating oil at the same time, thus increasing the cooling efficiency.

[0013] 2. This pneumatic lubricating oil internal circulation component works by pressing the rotating disc upwards, causing the hexagonal groove at the top of the rotating disc to cover the hexagonal block at the bottom of the oil filter. Rotating the rotating disc then causes the oil filter to rotate, loosening the threads between the oil filter and the mounting plate, thus detaching the oil filter from the mounting plate. At this point, the protective sleeve completely isolates the oil filter from the outside environment. When it is certain that the oil filter can be removed, pulling the pull column causes the pull column to move the locking pin, which then disengages from the outer wall of the oil filter, eliminating the fixing relationship of the protective sleeve. The protective sleeve can then be removed, the internal oil filter replaced, and the structure reassembled. Attached Figure Description

[0028] Working principle: When using this equipment, air is drawn in through the suction device 2. The main unit 1 pushes the air drawn in by the suction device 2 into the oil-gas separator 3 through the air pipe 2 8. The oil supply to the main unit 1 through the oil pipe 4 ensures that the air transmitted from the main unit 1 into the oil-gas separator 3 is an oil-gas mixture. The oil-gas separator 3 separates the oil and gas in the mixture. The oil settles to the bottom of the oil-gas separator 3, while the gas is transmitted to the interior of the cooling plate 17 through the air pipe 7. Finally, the compressed air cooled by the cooling plate 17 enters the external air storage tank and settles into the oil-gas separator 3. The lubricating oil is transferred to the interior of the cooling plate 17 through oil pipe 36, where it is cooled. The cooled lubricating oil then reaches the interior of the mounting plate 9 through oil pipe 25, and then the interior of the protective casing 10 through the mounting plate 9. It is filtered by the protective casing 10 and finally continues to supply lubricating oil to the interior of the main unit 1 through oil pipe 14. When the oil filter 12 needs to be replaced, the rotating disk 13 is pressed upwards, causing the hexagonal groove at the top of the rotating disk 13 to cover the hexagonal block at the bottom of the oil filter 12. At this time, the rotating disk 13 is rotated, which in turn causes the rotating disk 13 to drive the oil filter 12 to rotate. This causes the oil filter 12 to loosen through the threads of the mounting plate 9, allowing it to detach from the mounting plate 9. At this point, the protective sleeve 10 completely isolates the oil filter 12 from the outside environment. When it is certain that the oil filter 12 can be removed, pull the pull column 14, causing the pull column 14 to move the locking pin 16, thereby causing the locking pin 16 to disengage from the outer wall of the oil filter 12, thus eliminating the fixing relationship of the protective sleeve 10. At this point, the protective sleeve 10 can be removed, and the oil filter 12 inside can be replaced before resetting the structure. When using in summer, rotating the rotating column 24 causes the rotating column 24 to drive the sealing ball 11 to rotate, thus... The groove on the outer wall of the sealed ball 11 is parallel to the inlet pipe 23. At this time, the coolant inside the cooling plate 17 can reach the inside of the inner cooling pipe 21 through the inside of the inlet pipe 23. The water pump 19 is started, and the water pump 19 draws the cooling water inside the inner cooling pipe 21 into the inside of the return pipe 20 through the connecting pipe 22. The water then flows back to the inside of the cooling plate 17 through the return pipe 20, so that the coolant flows from the inside of the inner cooling pipe 21 and dissipates heat from the middle of the lubricating oil. The coolant outside the cooling plate 17 dissipates heat from the outside of the cooling oil pipe 18, and dissipates heat from both the inside and outside of the lubricating oil at the same time, which improves the cooling efficiency.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
