The invention relates to a
solid-liquid separation device for dredging mud in a ship lock approach channel, and belongs to the field of
solid-liquid separation devices. The device comprises a separation box for the desilting
machine and a feeding hopper arranged at the top of the separation box for the desilting
machine. A coarse separation unit is arranged below the feeding hopper, and a fine separation unit is arranged at the bottom of the separation box for the dredging
machine. The fine separation unit comprises a filter screen cylinder and two
extrusion filter cylinders; semi-arc grooves are uniformly formed in the bottom of the separation box for the dredging machine; the filter screen cylinder is rotationally arranged in the semi-arc groove; the two
extrusion filter cylinders are fixedly arranged on the two sides of the separation box for the dredging machine correspondingly and rotationally connected with the two ends of the filter screen cylinder correspondingly. A
discharge hole is formed in one end, deviating from the filter screen cylinder, of the
extrusion filter cylinder; a sealing unit is arranged at the
discharge hole; the sealing unit is used for opening or closing the
discharge hole; the filter screen cylinder is communicated with the two corresponding extrusion filter cylinders, and a
working space is formed; a filter pressing unit is arranged in the
working space in a sliding manner; the
solid-liquid separation device has the technical effects of the solid-liquid separation device for ship lock approach channel dredging mud.
