[0029] The outer surfaces of the plurality of springs 205 are slidably connected with a pressing ring 301, the top of the mounting frame 202 is fixedly connected with a plurality of connecting rods 302, the outer surfaces of the plurality of connecting rods 302 are all slidably connected with the inner wall of the pressing ring 301.

[0030] One end of the plurality of connecting rods 302 away from the mounting frame 202 is fixedly connected with a fixing frame 303, the inner wall of the fixing frame 303 is threadedly connected with a lead screw 304.

[0031] One end of the lead screw 304 close to the pressing ring 301 is rotatably connected with a limiting ring 305, the outer surface of the limiting ring 305 is fixedly connected with one side of the pressing ring 301 close to the lead screw 304.

[0032] One end of the lead screw 304 away from the pressing ring 301 is fixedly connected with a handle 306, and the bottom of the filter plate 201 is provided with a fan 104.

[0033] The outer surface of the collecting barrel 1 is fixedly connected with a lock ring 106, the inner wall of the lock ring 106 is threadedly connected with the outer surface of the barrel cover 101, and one side of the barrel cover 101 close to the collecting barrel 1 is rotatably connected with a rotating ring 401.

[0035] One specific application of the embodiment is that the collecting barrel 1 is connected to the unloading storage tank through the gas collecting pipe 102, and then the fan 104 is started. The liquid gas in the tank car is transported into the storage tank, and some gas generated is introduced into the inside of the collecting barrel 1 through the gas collecting pipe 102. The gas enters the inside of the collecting barrel 1 and passes through the filter plate 201 and is finally collected in the inside of the collecting barrel 1. Finally, it is transported into the inside of the required equipment through the gas outlet pipe 103. The filter plate 201 needs to be replaced after a long time of use. The barrel cover 101 is detached from the top of the collecting barrel 1 by rotating the barrel cover 101 counterclockwise. The handle 306 is rotated clockwise to drive the lead screw 304, so that the compression ring 301 moves downward. When the compression ring 301 moves downward, the compression ring 301 extrudes the limiting block 204 to move into the inside of the limiting rod 203. When the compression ring 301 contacts the mounting frame 202, the handle 306 is pulled to drive the mounting frame 202 to detach from the surface of the limiting rod 203, thereby driving the filter plate 201 to detach from the inside of the collecting barrel 1. After the filter plate 201 is cleaned and replaced, it is placed in the inside of the collecting barrel 1. The handle 306 is rotated counterclockwise to drive the fixing frame 303 away from the mounting frame 202. When the compression ring 301 moves to the top of the limiting block 204, the spring 205 in the compressed state pushes the limiting block 204 to move away from the limiting rod 203, thereby fixing the mounting frame 202 to the inner wall of the collecting barrel 1. The replacement of the filter plate 201 can ensure that the gas recycling system always has high filtering and recycling capacity, effectively intercepts and recycles leaked liquefied gas, reduces resource waste, and allows the filter plate 201 to be selected according to actual needs to select the appropriate type and specification of the filter plate 201 to adapt to different gas recycling needs.

[0036] After the filter plate 201 is replaced, the barrel cover 101 is placed on the top of the collection barrel 1, the rotating ring 401 at the bottom of the barrel cover 101 is aligned with the groove at the top of the collection barrel 1, and the barrel cover 101 is rotated clockwise, so that the barrel cover 101 drives the rotating ring 401 to extrude the sealing ring 402, and the sealing ring 402 is deformed while being extruded by the rotating ring 401, so that the sealing ring 402 can better adhere to the rotating ring 401, thereby increasing the sealing effect between the barrel cover 101 and the collection barrel 1. A good sealing effect can ensure that more leaked gas is captured and recycled by the absorption device, which helps to reduce environmental pollution.
