[0029] Reference Figure 1-4 As shown, this embodiment discloses a protective device 2 including a bracket 21, a first bolt 22 is threadedly inserted into one side of the bracket 21, a movable plate 23 is threadedly connected to one side of the first bolt 22, a connecting block 24 is fixedly connected to one side of the movable plate 23, and protective sleeves 25 are fixedly connected to both ends of the connecting block 24, and the size of the protective sleeves 25 is adapted to the size of the air inlet pipe 4 and the air outlet pipe 5. When the refrigeration oil and the refrigerant are separated, the mixed gas of the two will be sent into the interior of the tank body 1 through the air inlet pipe 4, and then the oil in the gas will form oil droplets after contacting the filter screen 7 inside the tank body 1, and then accumulate at the bottom of the tank body 1. After reaching a certain liquid level, the lubricating oil will return to the interior of the compressor through the oil outlet pipe 6 at the bottom, and the filtered gas refrigerant will be discharged through the exhaust pipe. After the air inlet pipe 4 and the air outlet pipe 5 are connected to the external pipe, the first bolt 22 can be rotated to move the first bolt 22 on the bracket 21, and then the first bolt 22 drives the movable plate 23 to move up and down, and then the movable plate 23 passes through the connecting block 24 to move the two protective sleeves 25 upward to the connection between the air inlet pipe 4 and the air outlet pipe 5 and the external pipe, and then the connection between the air inlet pipe 4 and the air outlet pipe 5 and the external pipe is shielded and protected. By using the protective device 2, the connection between the air inlet pipe 4 and the air outlet pipe 5 at the upper end of the tank body 1 and the external pipe can be shielded and protected to avoid the connection between the air inlet pipe 4 and the air outlet pipe 5 and the external pipe from being hit by external force, which then affects the sealing of the air inlet pipe 4 and the air outlet pipe 5, thereby improving the use effect of the separation device.
[0030] Reference Figure 1-4As shown, this embodiment discloses a first bolt 22 having a bearing 26 fixedly connected to one side thereof. The outer ring of the bearing 26 is fixedly connected to the movable plate 23. The bearing 26 reduces friction between the first bolt 22 and the movable plate 23, making it easier for the first bolt 22 to move the movable plate 23. A reinforcing plate 27 is fixedly connected to one side of the movable plate 23. The side of the reinforcing plate 27 facing away from the movable plate 23 is fixedly connected to the connecting block 24. The reinforcing plate 27 enhances the connection strength between the movable plate 23 and the connecting plate, preventing deformation at the connection between the movable plate 23 and the connecting plate. Several anti-slip blocks 28 are fixedly connected to one side of the first bolt 22. The anti-slip blocks 28 are evenly spaced and arranged on one side of the first bolt 22. The anti-slip blocks 28 increase friction between the first bolt 22 and the operator, making it easier for the first bolt 22 to rotate. A sliding groove 29 is formed on one side of the bracket 21. A sliding block 210 is slidably connected within the sliding groove 29 on one side of the bracket 21. The sliding block 210 is fixedly connected to the movable plate 23. The sliding block 210 that moves inside the sliding groove 29 on one side of the bracket 21 can improve the stability of the moving plate 23 during movement, thereby improving the stability of the movement of the protective cover 25.

When using the protective device 2, the bracket 21 can be moved so that the fixing plate 33 on one side of the bracket 21 is inserted into the placement block 31, and then the second bolt 32 is rotated so that the second bolt 32 passes through the placement block 31 and is connected and fixed to the fixing plate 33, and then the position of the bracket 21 on the tank body 1 is fixed. By using the fixing device 3, the protective device 2 can be quickly fixed to the side of the tank body 1 close to the air inlet pipe 4 and the air outlet pipe 5, thereby facilitating the operator's subsequent use of the protective device 2.
[0032] Reference Figure 1-4 As shown, this embodiment discloses guide plates 34 fixedly connected to both sides of the placement block 31. The guide plates 34 are arranged obliquely on both sides of the placement block 31. By using the guide plates 34, the entrance and exit dimensions of the placement block 31 are increased, making it easier to insert the fixed plate 33 into the placement block 31. A gasket 35 abuts one side of the second bolt 32, and one side of the gasket 35 abuts the placement block 31. By using the gasket 35, the contact area between the second bolt 32 and the placement block 31 is increased, allowing the second bolt 32 to more firmly fix the fixed plate 33.
[0033] Working principle: When separating the refrigeration oil and the refrigerant, the mixed gas of the two will be sent into the tank body 1 through the air inlet pipe 4, and then the oil in the gas will contact the filter screen 7 inside the tank body 1 to form oil droplets, which will then accumulate at the bottom of the tank body 1. After reaching a certain liquid level, the lubricating oil will return to the compressor through the oil outlet pipe 6 at the bottom, and the filtered gas refrigerant will be discharged through the exhaust pipe. After the air inlet pipe 4 and the air outlet pipe 5 are connected to the external pipe, the first bolt 22 with the anti-sliding block 28 can be rotated to make the first bolt 22 move on the bracket 21, and then the first bolt 22 drives the movable plate 23 to move up and down. At this time, the sliding block 210 moving inside the sliding groove 29 on one side of the bracket 21 is used to improve the stability of the movable plate 23 during movement, and then the movable plate 23 passes through the connecting block 24 to make the two protective sleeves 25 move upward to the connection between the air inlet pipe 4 and the air outlet pipe 5 and the external pipe, and then the air inlet pipe 4 and the air outlet pipe 5 are connected to the external pipe for shielding and protection. By using the protective device 2, the air inlet pipe 4 and the air outlet pipe 5 at the upper end of the tank body 1 and the external pipe connection can be shielded and protected, avoiding the air inlet pipe 4 and the air outlet pipe 5 being connected to the external pipe by external force collision, thereby affecting the sealing of the air inlet pipe 4 and the air outlet pipe 5, thereby improving the use effect of the separation device.
[0034] When using the protective device 2, the bracket 21 can be moved so that the fixing plate 33 on one side of the bracket 21 is inserted into the placement block 31 with the guide plate 34, and then the second bolt 32 is rotated so that the second bolt 32 passes through the gasket 35 and the placement block 31, and then is connected and fixed to the fixing plate 33, and then the position of the bracket 21 on the tank body 1 is fixed. By using the fixing device 3, the protective device 2 can be quickly fixed to the side of the tank body 1 close to the air inlet pipe 4 and the air outlet pipe 5, so as to facilitate the operator to use the protective device 2 later.
