The invention discloses a screw type sludge dewatering machine in the technical field of sludge dewatering. The screw type sludge dewatering machine comprises a stirrer and a rack, wherein a fixed casing is arranged at the top of the rack; a fixed plate is arranged on the right side of the fixed casing; the fixed plate is uniformly provided with discharge openings; a connecting block is movably arranged on the right side of the fixed plate; baffles matched with the discharge openings are arranged on the outer side of the connecting block; a gearing ring is arranged on the outer side of each baffle; a gear is arranged on the left side of a rotating rod; a rotary turntable drives the gear on the rotating rod to rotate; the baffles on the gear rings are driven by engagement of the gear and the gear rings to rotate; partial discharge openings are shielded by rotation of the baffles, so that the sizes of discharging spaces of the discharge openings are changed, and the dewatering efficiencyof the sludge is improved; the space between the diameter of the fixed casing and screw blades is linearly and progressively decreased from left to right in sequence, pressurizing of sludge is improved and the dewatering rate is improved.
Description
technical field [0001] The invention relates to the technical field of sludge dewatering, in particular to a screw stacking sludge dewatering machine. Background technique [0002] Sludge is an inevitable product of sewage treatment, which contains high water content. In order to reduce the pollution of sludge to the environment, sludge is often dehydrated before being discarded. At present, the common sludge dewatering machines include plate and frame sludge dewatering machines, belt sludge dewatering machines and stacked screw sludge dewatering machines. However, the size of the outlet of the existing sludge dewatering machines is fixed and cannot be adjusted. Therefore, There is a need for a stacked screw sludge dewatering machine. Contents of the invention [0003] The object of the present invention is to provide a screw stacking sludge dewatering machine to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the abov...
