The invention is further illustrated below with reference to the figures and examples. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. Needless to say, a person skilled in the art realizes that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

As shown in fig. 1 to fig. 3, the filter press of the present embodiment includes a frame 1, two ends of the frame 1 are respectively provided with an oil cylinder 2, the oil cylinders 2 at the two ends are arranged oppositely, that is, the telescopic rods of the oil cylinders 2 at the two ends face each other. All fixedly on the telescopic link of the hydro-cylinder 2 of each end be equipped with hollow movable filter plate 3, two movable filter plates 3 all are equipped with filter-pressing groove 4 on being close to each other on the surface, and filter-pressing groove 4 of the movable filter plate 3 at both ends aligns the pressfitting and forms filter-pressing chamber 5, and the cavity of movable filter plate 3 is the play liquid chamber during filter-pressing.

The frame 1 is provided with rollers 6 below the movable filter plates 3, a tensioning device 7 is arranged between the rollers 6 and the lower ends of the movable filter plates 3, the tensioning device 7 is arranged on the movable filter plates 3 through a connecting piece, a guide roller 8 is arranged above the movable filter plates 3, one end of the guide roller 8 is connected with the movable filter plates 3 at two ends through a connecting rod 15, and the other end of the guide roller 8 is also hinged with the movable filter plates 3 at two ends through a connecting rod 15.

The roller 6 at one end is wound with filter cloth 9, the free end of the filter cloth 9 on the roller 6 passes through the tension device 7 at the end, the filter pressing groove 4 of the movable filter plate 3 at the end, the upper end of the guide roller 8, the filter pressing groove 4 of the movable filter plate 3 at the other end and the tension device 7 at the other end in sequence, and then is connected with the roller 6 at the other end, and the roller 6 at the other end is in transmission connection with the driving device through the electric clutch 10.

A liquid inlet pipe 12 is arranged between the lower ends of the movable filter plates 3 at the two ends, a high-pressure pump (not shown in the figure) can be arranged on the liquid inlet pipe 12, a clamping groove 13 for clamping the liquid inlet pipe is arranged on the movable filter plate 3 corresponding to the liquid inlet pipe 12, and an elastic sealing gasket can be arranged on the clamping groove 13. The bottom end of the movable filter plate 3 is provided with a liquid outlet 14. The liquid outlet hole 14 is connected with a water outlet hose.
