[0021] Please refer to Figures 1-3 , an embodiment provided by the present utility model: a polysiloxane adsorption device, which includes a mounting base 1. A adsorption tank 2 is fixedly provided at the top end of the mounting base 1. A feed tank 4 is fixedly provided at the top end of the mounting base 1 close to the adsorption tank 2. A second pipeline 5 is inserted on the side wall of the feed tank 4 and is connected to the top end of the adsorption tank 2 for communication.

A second valve 53 is provided at the end of the second pipeline 5 close to the adsorption tank 2. By sequentially opening the first valve 51 and the second valve 53, the feed tank 4 and the adsorption tank 2 are connected. Starting the booster pump 52 can pump the raw material into the interior of the adsorption tank 2 for adsorption filtration, improving the convenience of raw material transportation. A collection tank 9 is fixedly provided at the top end of the mounting base 1 close to the adsorption tank 2. A first pipeline 3 is inserted on the side wall of the adsorption tank 2 and is sequentially connected to the feed tank 4 and the collection tank 9 for communication. A valve A 31 is provided at the end of the first pipeline 3 close to the feed tank 4. A feed port 41 is opened at the top end of the feed tank 4. Opening the valve A 31 can make the filtered raw material enter the feed tank 4 again, facilitating circular filtration. A valve B 32 is provided at the top end of the first pipeline 3 close to the collection tank 9. Opening the valve B 32 can connect the adsorption tank 2 and the collection tank 9, facilitating the collection of qualified products. A vent pipe 6 is inserted at the middle position of the top end of the adsorption tank 2. A third valve 61 is installed at the bottom end of the vent pipe 6. An air pump 7 is fixedly provided on the surface of the mounting base 1 close to the adsorption tank 2. The output end of the air pump 7 is inserted with a fourth pipeline 8. The other end of the fourth pipeline 8 is inserted on the side wall of the adsorption tank 2. A fourth valve 81 is provided at the end of the fourth pipeline 8 close to the adsorption tank 2. Two limiting frames 10 are fixedly provided on the inner side wall of the adsorption tank 2. Adsorption frames 11 are provided on the inner side walls of the limiting frames 10. The adsorption frames 11 are detachable and replaceable. The adsorption frame 11 includes a filter cloth 111 clamped inside the limiting frame 10. When the surface of the filter cloth 111 is blocked, after discharging the raw material inside the adsorption tank 2, the valve A 31, the valve B 32, the second valve 53, and the third valve 61 are sequentially closed, and then the fourth valve 81 is opened. Starting the air pump 7 can pump clean air into the adsorption tank 2. The air flows from bottom to top inside the adsorption tank 2, purging the impurities attached to the top end of the limiting frame 10. When the internal pressure increases, the compressed air instantaneously opening the third valve 61 can carry the impurities and discharge them from the vent pipe 6 out of the interior of the adsorption tank 2, thereby preventing the limiting frame 10 from being blocked, and thus improving the adsorption quality and efficiency of the limiting frame 10.

[0022] A pressure gauge 82 is installed at the end of pipeline four 8 near valve four 81. The pressure gauge 82 is connected to the adsorption tank 2 through pipeline four 8. Opening valve four 81 can balance the internal air pressure of pipeline four 8 and the adsorption tank 2, thus facilitating the measurement of the internal air pressure of the adsorption tank 2 and improving the precision and safety of purging.

[0023] Polytetrafluoroethylene balls 112 and humic acid particles 113 are successively filled inside the filter cloth 111. The diameter of the polytetrafluoroethylene balls 112 is 1 - 3 cm; the particle size of the humic acid particles 113 is 50 - 2000 μm, and the filtration precision of the filter cloth 111 is 20 - 50 μm, thereby improving the filtration quality.

[0024] Working principle: When this polydimethylsiloxane adsorption device is in use, the operator first connects an external power supply, pours the raw material to be adsorbed and filtered into the interior of the feed tank 4 from the feed inlet 41, then successively opens valve one 51 and valve two 53 to start the booster pump 52 to pump the raw material into the adsorption tank 2 for pressure filtration, enabling the raw material to pass through the adsorption frame 11 in sequence to complete filtration. Opening valve A 31 allows the filtered raw material to enter the feed tank 4 again, facilitating circular filtration. When the filtration and adsorption are qualified, opening valve B 32 enables the adsorption tank 2 and the collection tank 9 to be connected, facilitating the collection of qualified products. When the surface of the filter cloth 111 is blocked, after discharging the raw material inside the adsorption tank 2, valve A 31, valve B 32, valve two 53, and valve three 61 are successively closed, then valve four 81 is opened, and the air pump 7 is started to pump clean air into the adsorption tank 2. The air flows upward from the bottom inside the adsorption tank 2 to purge the impurities attached to the top of the limit frame 10. When the internal pressure increases, the compressed air instantaneously opening valve three 61 can carry the impurities and discharge them from the relief pipe 6 out of the interior of the adsorption tank 2, thus preventing the limit frame 10 from being blocked and improving the adsorption quality and efficiency of the limit frame 10.

[0025] Secondly, the pressure gauge 82 is connected to the adsorption tank 2 through pipeline four 8. Opening valve four 81 can balance the internal air pressure of pipeline four 8 and the adsorption tank 2, thus facilitating the measurement of the purging air pressure inside the adsorption tank 2 and improving the precision and safety of purging.
