Filtering device for glutathione production

The utility model provides a filtering device for glutathione production, which comprises a centrifugal filtering mechanism and a plate type filtering mechanism, the centrifugal filtering mechanism comprises a separating box, a filtering barrel, a filtering inner barrel, a rotating shaft and a motor, and the plate type filtering mechanism comprises a filtering tank and a filtering net arranged in the filtering tank. A secondary filtering liquid inlet is formed in the top of the filtering tank, and a secondary filtering liquid outlet is formed in the bottom of the filtering tank; a liquid outlet is formed in the bottom of the separation box and is communicated with the secondary filtering liquid inlet through a pipeline. Centrifugal filtration and plate-type filtration are combined, so that a multi-separation effect is achieved, the filtration quality is further improved, and the impurity content of filtrate is reduced; meanwhile, a detachable filtering inner barrel is additionally arranged in a filtering barr
