The invention discloses a
sludge concentration and
dehydration device which comprises a mixer, an inlet of the mixer is connected with a
sewage inlet
pipe, a liquid outlet of the mixer is communicated with an inlet of a stirring box through a pipeline, an outlet of the stirring box is communicated with a concentration box through a liquid outlet
pipe, a concentration mechanism is arranged in the concentration box, and a concentration box
discharge port is formed in the side wall of the concentration box. A material guide cover is arranged on the side face of the concentration box, a discharging port of the material guide cover is communicated with the
dehydration box, and a pressing plate is arranged on the upper portion of a
sludge outlet in the
dehydration box. According to the
sludge dewatering device,
sewage and medicines are primarily flocculated through the mixer, then a
mixed solution is guided into the stirring box for secondary
flocculation, so that the
flocculation effect of sludge is enhanced,
dewatering is facilitated, then the sludge passes through the concentration mechanism, the concentrated sludge enters the
dewatering box, the low-concentration sludge is concentrated, the
solid content of the sludge is increased, and the
sludge dewatering effect is improved. The
water content of the sludge is reduced again through the dewatering box, and the device is suitable for dewatering the high-flow low-concentration sludge.
