Detailed description of the invention
With reference to a kind of filter press shown in Fig. 1, it columniform closed container 1 comprising support 16 and be horizontally installed on support 16, charging pump 2, filter press plate assembly, pressing plate 3 and hydraulic cylinder 4, the right-hand member of closed container 1 is provided with sealing cover body 5, the bottom of closed container 1 is provided with delivery port 6 near the position of right-hand member, the upper left quarter of closed container 1 is provided with charging aperture 7, charging aperture 7 place connects charging pump 2, described pressing plate 3 is arranged on the inner left end of closed container 1, the push rod of hydraulic cylinder 4 to penetrate in closed container 1 and is fixedly connected with pressing plate 3, described filter press plate assembly comprises the filter press plate 8 of multi-disc circle and is arranged on the thrust plate 13 of low order end, the right-hand member of closed container 1 is provided with internal thread, sealing cover body 5 is provided with the external screw thread matched, the left end of sealing cover body 5 withstands in straight push pedal, filter press cloth 9 is filled with between adjacent filter press plate 8, every sheet filter press plate 8 is provided with for material through hole 10, expansion link 11 is provided with between adjacent filter press plate 8, minimum length after expansion link 11 shrinks is less than the minimum spacing of filter press plate 8, described lid is provided with push rod 12, push rod 12 extends in closed container 1, pass filter press cloth 9 successively and be connected with the filter press plate 8 of the leftmost side, described thrust plate 13 is fixedly connected with the filter press plate 8 of the rightmost side, the step surface spacing to thrust plate 13 is provided with in closed container 1.
In order to make being parallel to each other between filter press plate 8, be provided with 4 groups of expansion links 11 between adjacent filter press plate 8, expansion link 11 is distributed on filter press plate 8 in foursquare corner position.
In order to the stroke of the push rod of hydraulic control cylinder 4, in described closed container 1, be provided with the limit switch controlling push rod stroke.
