A filter plate 10 is fixedly connected, and the filter plate 10 is located on the rear side of the limiting gasket 9. Through the setting of the filter plate 10, the slurry filtered by the double-layer sliding tube 7 can be secondary filtered, and the sediment in the slurry can be further adsorbed.
