[0032] As Figures 1 to 7 shown, a gas separation device in an embodiment of the present utility model includes: a gas separation cylinder 1, a cleaning mechanism 2 and a discharge mechanism 3.

[0033] As Figure 1 shown, the inside of the gas separation cylinder 1 is used to store the mixed gas. A filter element 101 is installed inside the gas separation cylinder 1, and the filter element 101 can allow part of the air to pass through and filter the mixed gas. A gas separation membrane 107 is installed on the filter element 101, and part of the air can enter the inside of the gas transmission pipe 106 through the gas separation membrane 107, so as to separate the mixed gas.

[0034] As Figure 1 shown, a sealing cover 102 is installed at one end of the gas separation cylinder 1 away from the rotating sleeve 201.

[0039] As Figures 1 to 5 shown, a fixing plate 206 is fixed inside the gas separation cylinder 1. The fixing plate 206 can block the air between the plurality of rotating blades 202, so that the air between the plurality of rotating blades 202 can be compressed. Ventilation grooves are drilled on the fixing plate 206. Through the ventilation grooves, the air between a pair of rotating blades 202 can enter the interior of the gas separation cylinder 1.

[0040] As Figures 1 to 3 shown, fixing rings 207 are arranged on both sides of the rotating plate 204. The fixing rings 207 are fixedly connected to the gas separation cylinder 1. The fixing rings 207 can support the rotating plate 204, so that the rotating plate 204 is not easily deflected during rotation. A bearing 208 is installed between the rotating sleeve 201 and the air delivery pipe 106. The bearing 208 is used to support the rotating sleeve 201, so that the rotating sleeve 201 is more stable during rotation.

[0041] As Figures 4 to 6As shown, the discharge mechanism 3 is installed on one side of the gas separation cylinder 1. The discharge mechanism 3 includes a fixed sleeve 301, and the fixed sleeve 301 is used to support the cover plate 302. The cover plate 302 is installed on the fixed sleeve 301, and the cover plate 302 can block the opening on the fixed sleeve 301. An air outlet pipe 303 is fixed on the cover plate 302, and the air inside the fixed sleeve 301 can be pumped out through the air outlet pipe 303.

[0042] As Figures 2 to 4 shown, a filter block 311 is installed inside the air outlet pipe 303, and the filter block 311 is used to block impurities inside the fixed sleeve 301. A plurality of air suction pipes 304 are installed on the rotating sleeve 201, and the gas inside the gas separation cylinder 1 can be sucked into the rotating sleeve 201 through the air suction pipes 304.

[0043] As Figures 6 to 7 shown, a plurality of fixing blocks 305 are fixed on the fixed sleeve 301, and the fixing blocks 305 are used to support the mounting bolts 307.

[0044] As Figure 4 shown, sealing members 308 are installed between the cover plate 302 and the fixed sleeve 301 and the air delivery pipe 106. The sealing members 308 can block the gaps between the cover plate 302 and the fixed sleeve 301 and the air delivery pipe 106, so that the inside of the fixed sleeve 301 is in a closed state.

[0045] As Figure 4 shown, a rotating plate 309 is further fixed on the rotating sleeve 201. The rotating plate 309 is used to support the rotating brush 310 and can drive the rotating brush 310 to rotate. The rotating brush 310 is installed on the rotating plate 309, and the rotating brush 310 is used to clean the sundries on the filter block 311, so that the sundries are not easily blocked on the filter block 311.

[0046] During specific use, a mixed gas is injected into the gas separation cylinder 1 through the air inlet pipe 104. The mixed gas can push the rotating blades 202 to move, so as to drive the rotating sleeve 201 to rotate. When the rotating blades 202 move to the position of the ventilation slots, the air between a pair of rotating blades 202 can enter the gas separation cylinder 1. The mixed gas inside the gas separation cylinder 1 is filtered through the filter element 101, and part of the gas can enter the air delivery pipe 106 through the gas separation membrane 107 and be discharged through the air delivery pipe 106, so as to separate the gas;

[0047] During the rotation of the rotating sleeve 201, it can drive a plurality of connecting blocks 203 to rotate, thereby driving the rotating plate 204 and the cleaning brush 205 to rotate, so that the cleaning brush 205 can stir the impurities adsorbed on the filter element 101, making it difficult for the impurities to block the filter element 101.

[0048] After the gas separation is completed, the exhaust pipe 105 and the air delivery pipe 106 are blocked. Clean gas is injected into the gas separation cylinder 1 through the air inlet pipe 104, and the air inside the fixed sleeve 301 and the rotating sleeve 201 is pumped out through the air outlet pipe 303, creating a negative pressure inside the rotating sleeve 201. As a result, the air inside the gas separation cylinder 1 can carry impurities and enter the rotating sleeve 201 and the fixed sleeve 301 through the suction pipe 304, enabling the fixed sleeve 301 to collect the impurities. The rotating sleeve 201 can also drive the rotating plate 309 to rotate, and the rotating plate 309 can drive the rotating brush 310 to clean the impurities adsorbed on the filter block 311, making it difficult for the impurities to block the filter block 311.
