[0025] like Figure 1 As shown, this embodiment provides a compressor oil mist recovery device, including a cover body 1 and an oil storage tank 2, wherein an air vent is provided on the upper portion of the cover body 1, a baffle 3 is provided on the inner side of the cover body 1, a gap is provided between the baffle 3 and the inner wall of the cover body 1, the baffle 3 is used to block the air vent, the bottom of the cover body 1 is open, a seal buckle is detachably provided at the opening, the seal buckle is used to seal the opening, an oil pipeline 4 is connected to the bottom of the cover body 1, and the other end of the oil pipeline 4 is connected to the oil storage tank 2.

[0026] The compressor oil mist recovery device provided in this embodiment has a cover body 1 that is sleeved on the outer side of the breathing valve through the bottom opening, and then the opening is sealed by a sealing buckle, so that the other parts of the cover body 1 except the vent hole are sealed to prevent oil leakage. The cover body 1 can block the splashing oil mist, and the blocked oil mist will adhere to the inner wall of the cover body 1 and flow into the bottom along the inner wall. The inside of the cover body 1 maintains air circulation with the outside through the vent hole. The blocking body 3 is located at the lower side of the vent hole, separating the lower part of the inner side of the cover body 1 from the vent hole. The oil mist in the rising gas can be blocked by the blocking body 3, and the blocked oil mist adheres to the blocking body 3. Excessive oil mist will fall to the bottom of the cover body 1, and the air continues to rise to the vent hole along the gap between the blocking body 3 and the inner wall of the cover body 1. The oil accumulated at the bottom of the cover body 1 enters the oil storage tank 2 through the oil pipeline 4 for storage for further recycling, thereby realizing the recovery of the oil mist splashed at the breathing valve, improving the utilization rate of the lubricating oil, and preventing the oil mist from polluting the environment.

[0027] Specifically, the size of the opening at the bottom of the cover body 1 is determined according to the size of the breathing valve, so that the cover body 1 can be mounted outside the breathing valve from the opening. Under the premise of meeting the requirements, the opening is as small as possible so that the seal can seal the opening. The caliber of the opening can be less than or equal to the inner diameter of the bottom of the cover body 1, and the oil pipeline 4 can be connected to the baffle body 3, or it can also be connected to the cover body 1, and the oil pipeline 4 is sealed with the baffle body 3 or the cover body 1. Preferably, a valve 9 is provided on the oil pipeline 4. Specifically, the valve 9 can be a hand valve, which can be kept open at ordinary times, so that the oil inside the cover body 1 can continuously enter the oil storage tank 2 through the oil pipeline 4. When oil transportation is not needed, for example, when the oil storage tank 2 is full or needs to be repaired, the valve 9 can be closed.

[0028] Preferably, Figure 2 As shown, the blocking body 3 includes a bracket 31 and a baffle 32 arranged on the bracket 31. The bracket 31 is arranged on the inner wall of the cover body 1. The baffle 32 is horizontally located in the middle of the cover body 1 and has a gap with the inner wall of the cover body 1, which is used to block the vent hole. One end of the bracket 31 is fixed to the inner wall of the cover body 1, and the other end of the bracket 31 is fixed to the baffle 32, so that the baffle 32 is in a horizontal state, so that the baffle 32 blocks the rising gas. The oil mist in the gas contacts the baffle 32 and adheres to the baffle 32. The gas after the oil mist is removed continues to rise through the gap between the baffle 32 and the inner wall of the cover body 1, and circulates with the outside of the cover body 1 through the vent hole.

[0029] This embodiment provides an implementation method, the inner diameters of the top and bottom of the cover body 1 are smaller than the inner diameter of the middle part, the inner diameter of the cover body 1 gradually increases from the top to the middle part, the vent hole is located at the top of the cover body 1, and the baffle 32 is located on the inner side of the cover body 1 and facing the vent hole.

[0030] The upper part of the cover body 1 is in a shape that is gradually transitioned from small at the top to large at the bottom. The inner wall of the upper part of the cover body 1 is in an inclined state, so that when the rising gas passes through the gap between the baffle 32 and the inner wall of the cover body 1, the inner wall of the cover body 1 will also block the gas, thereby further blocking the oil mist in the gas and making the oil mist in the gas more thoroughly recovered. The inner diameter of the lower part of the cover body 1 is smaller, which helps to collect the lubricating oil in the cover body 1 for recovery.

[0031] In order to install the bracket 31 on the inner side of the cover body 1, in this embodiment, the bracket 31 includes at least three inclined support rods, all of which are evenly arranged along the circumferential direction, one end of the support rod is arranged at the bottom of the baffle 32, and the baffle 32 is located at the upper part of the cover body 1, and the other end of the support rod is clamped on the inner wall of the cover body 1. In this embodiment, the cover body 1 is in a shape with small ends and a large middle, and the bracket 31 includes at least three support rods. The bracket 31 is in a cone shape with a large bottom and a small top. The overall shape of the bracket 31 can match the shape of the inner wall of the cover body 1. When the bracket 31 is installed in the cover body 1, it can be clamped on the inner wall of the lower part of the cover body 1, and the baffle 32 is fixed to the top of the bracket 31 and is located at the upper part of the cover body 1.

[0032] This embodiment also provides an implementation method, in which the inner diameter of the top of the cover body 1 is smaller than the inner diameter of the bottom, the inner diameter of the cover body 1 gradually increases from the top to the bottom, the vent hole is located at the top of the cover body 1, and the baffle 32 is located at the lower side of the vent hole and directly facing the vent hole. Specifically, the cover body 1 as a whole is in a shape that gradually transitions from small at the top to large at the bottom, and the inner wall of the cover body 1 is in an inclined state, so that when the rising gas passes through the gap between the baffle 32 and the inner wall of the cover body 1, the inner wall of the cover body 1 will also block the gas, thereby further blocking the oil mist in the gas, so that the oil mist in the gas can be recovered more thoroughly.

[0033] In order to filter the recovered lubricating oil, in this embodiment, at least one filter layer 5 is provided in the oil storage tank 2. Specifically, the filter layer 5 can be a filter plate, a filter screen or other structure with filtering function, and three filter layers 5 are provided at the upper position inside the oil storage tank 2 to filter and purify the recovered lubricating oil.

[0034] In this embodiment, the bottom of the oil storage tank 2 is connected to an oil drain pipe 6, and an oil pump 7 is provided on the oil drain pipe 6. The oil in the oil storage tank 2 can be discharged through the oil pump 7 for recycling. Preferably, a switch 8 is provided on the oil drain pipe 6, and the switch 8 is located between the oil storage tank 2 and the oil pump 7. The switch 8 can be a manual valve or an automatic control valve, which is used to switch the outlet of the oil storage tank 2. When the switch 8 is closed, the lubricating oil is stored in the oil storage tank 2. When the switch 8 is opened, the lubricating oil in the oil storage tank 2 can be discharged through the oil drain pipe 6. It is opened when the oil is full and closed when the oil is exhausted.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
