Abstract

The invention relates to the field of glass flour sewage, in particular to a volute type sludge dehydrator applied to glass flour and water separation. The volute type sludge dehydrator comprises a rack, a stirring flocculation device and a dehydrating device. The dehydrating device comprises a water receiving tank, a spiral shaft and a volute body. The volute body comprises a fixed ring and a movable ring. A drainage outlet is formed in the water receiving tank. The stirring flocculation device comprises a water collecting tank, a water suction pipe and a water pump. A water inlet pipe, a drug inlet pipe and a drainage pipe are arranged on the water collecting tank. The drainage pipe communicates to the dehydrating device. A butterfly valve is arranged on the drainage pipe. The water collecting tank is divided into a reaction chamber, a settling chamber and a clean water cavity through three partition plates. A first overflow port is formed in the partition plate between the reactionchamber and the settling chamber, and a second overflow port is formed in the partition plate between the settling chamber and the clean water chamber. The dehydrator solves the technical problem in the prior art that the water collecting part is easily blocked and the drainage efficiency is low as glass flour and water are separated.

Description

technical field [0001] The invention relates to the field of glass powder sewage treatment, in particular to a screw-stacked sludge dewaterer applied to the separation of glass powder and water. Background technique [0002] Chinese Patent No.: CN201510498260.0 discloses a stacked screw sludge dewatering machine, including a stirring flocculation device and a dehydration device. The dehydration device includes a first mud inlet, a first mud outlet, a stacked screw body, a bracket plate, a Shaft, frame and first power device, the stacked screw body includes a fixed ring and a moving ring, the fixed ring is fixedly connected with the bracket plate, the screw shaft is located inside the cylindrical cavity formed by the fixed ring and the moving ring, the screw shaft and the first power The device is fixedly connected, and the bracket plate and the screw shaft are fixed on the frame. With the above structure, it is not easy to be blocked, the dehydration rate is improved and the...
