The invention relates to the technical field of environment, and more specifically discloses an integrated mini-type sludge solid-liquid separation device. The integrated mini-type sludge solid-liquidseparation device disclosed by the invention is capable of controlling the hammering extent of a hammering piece, the compression degree of springs on a spring sleeve rod can also be regulated through a hammering buffer regulating piece, so that the hammering buffer degree can be regulated. A sludge tank is connected to the inner part of a base in a sliding way; the lower end of the sludge tank is connected and communicated with a water outlet pipe; a guiding groove is formed in the upper end of the base; the guiding groove is communicated with the inner part of the base; the lower end of a T-shaped groove seat is fixedly connected with a hammering plate; the hammering plate is connected into the guiding groove in the sliding way; T-shaped grooves are respectively formed in the left end and the right end of the T-shaped groove seat; two T-shaped blocks are arranged; the two T-shaped blocks are respectively connected into the two T-shaped grooves in the sliding way; the upper ends of the two T-shaped grooves are fixedly connected with screw rod seats; two external threaded rods I are respectively and rotationally connected to the two screw rod seats; the lower ends of the screw rodseats are connected to the lower ends of the two T-shaped grooves through mounted bearings.
