DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figures 1 to 4As shown, this embodiment includes a filter cylinder 1, a filter cover 2 and a screw 3. A mounting body 13 is formed on the upper end of the filter cylinder 1. The mounting body 13 and the filter cover 2 are both rectangular. The upper end surface of the mounting body 13 is completely fitted with the lower end surface of the filter cover 2. The mounting body 13 and the filter cover 2 are fixed by bolts 10 installed at the four corners. A plurality of longitudinally stacked filter sheets 11 are arranged inside the filter cylinder 1. A mounting groove 21 is integrally formed below the filter cover 2. An upper fixing sheet 4 is installed in the mounting groove 21. The upper fixing sheet 4 is fitted with the topmost filter sheet 11. A lower fixing sheet 5 is fitted and fixed to the bottom of the bottommost filter sheet 11. The upper fixing sheet 4 and the lower fixing sheet 5 are fixed together. All filter plates 11 are fixed and limited, the screw 3 passes through the filter cover 2 and extends into the interior of the filter cylinder 1, the screw 3 passes through the upper fixed plate 4 and the filter plate 11 and extends out of the lower fixed plate 5, the outer end surface of the screw 3 is connected to the filter plate 11, so that the rotation of the screw 3 can drive the filter plate 11 to operate, and a valve handle 6 is fixed to the upper end of the screw 3, and the valve handle 6 can control the rotation of the screw 3. The rotation of the screw 3 can be controlled by the valve handle 6, so as to control the gap between the filter plates 11 and achieve the purpose of controlling the filtration purity.
