[0040] The organic silicon rubber filter device disclosed in the present invention is used for recovering waste organic silicon rubber filter:

[0041] The waste rubber raw material is added into the buffer tank 2 through the organic silicon inlet pipe 201, and the raw material is initially filtered through the screen 301. The piston plate 4 is controlled to move downward and pressurized by the push cylinder 5 to accelerate the filtering effect. After the initial filtering, the larger particle pollutants are filtered out, and the raw material then flows evenly into the coarse filter screen 601 on the coarse filter frame 6 through the organic silicon outlet pipe 202. At the same time, the motor 9 is operated to make the coarse filter frame 6 rotate continuously, so that the raw material is evenly distributed on different positions of the coarse filter screen 601, and the raw material itself flows to the coarse filter screen 601. The central flow ensures the uniformity of the coarse filtration and improves the coarse filtration efficiency. The raw materials after the coarse filtration fall into the fine filter cartridge 12 from the discharge pipe 111. After the fine filtration is completed by the inner ceramic filter cartridge 13 and the glass fiber filter cartridge 14, the raw materials fall into the adsorption cartridge 17 from the annular net 121. The adsorption cartridge 17 can use organic silicon adsorption resin or activated carbon material to optimize the adsorption performance and specifically remove soluble organic matter or other specific pollutants in the organic silicon filter glue. After the entire filtration operation is completed, the organic silicon material is directly discharged from the discharge pipe 18.

[0042] After a certain period of filtering operation, the filtering mechanism may be clogged, resulting in a decrease in filtering efficiency. In this case, flushing can be performed through the backwash water pipe 20. Before flushing, the flip handle 16 is manually operated to rotate the fine filter cartridge 12 180°. The cleaning water input by the backwash water pipe 20 passes through the fine filter cartridge flushing pipe 2001 and then flushes the filter element in the fine filter cartridge 12 through the water outlet branch pipe 221. Then the cleaning water falls into the adsorption cylinder 17 and is discharged through the drain pipe 19.

[0043] During the backwashing process, the three-way valve 21 is adjusted to allow the adsorption cylinder flushing pipe 2002 to inject cleaning water into the bottom of the filter box 1 . The cleaning water passes through the adsorption cylinder 17 and discharges the impurities and waste generated by the filtration through the drain pipe 19 .
