Abstract

The invention discloses a sludge dewatering device. The sludge dewatering device comprises a centrifugal cylinder, a screw auger and an outer shell; the centrifugal cylinder and the outer shell are mounted by forming a certain dewatering gap, the centrifugal cylinder can rotate relative to the outer shell at a high speed under the action of a drive device, the cylinder wall of the centrifugal cylinder is a filtering cylinder wall; the screw auger is mounted in the centrifugal cylinder through a transmission component and rotates at a certain speed ratio to the centrifugal cylinder; a sludge inlet hopper and a sludge outlet are respectively arranged at two ends of the centrifugal cylinder along the rotating axis of the centrifugal cylinder, and are both mounted relatively statically with ashell body; a drainage port is arranged at the bottom part of the shell body; a drying device is further arranged at the sludge outlet; the arrangement of combination of centrifugal dewatering and a feed mechanism is adopted, the ventilation and the temperature control are designed in a matching way through combination, so that the sludge dewatering device is simple in structure and convenient tooperate, has an excellent dewatering effect at certain energy consumption, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sludge dewatering device. Background technique [0002] Sludge is an inevitable product of sewage treatment in sewage treatment plants and sewage stations. Untreated sludge entering the environment will directly bring secondary pollution to water bodies and the atmosphere, and it will also affect the ecological environment and human activities. would pose a serious threat. Therefore, the treatment of sludge is very cautious, and the treatment of sludge can be divided into two types: sludge dehydration process and sludge drying process. [0003] Sludge dewatering machine is a kind of sludge treatment equipment with continuous operation. Because of its low moisture content in sludge, stable operation, low energy consumption, relatively simple control and management, and convenient maintenance, it has been widely used in industrial, mining, and sewage treatment industrie...
