Description

technical field

[0001] The invention relates to the technical field of sewage treatment equipment, in particular to a screw conveyor. Background technique

[0002] At present, the dehydrated cake in the sludge dehydration workshop of the sewage treatment plant is generally transported by a screw conveyor. Due to the needs of the process flow and the ability of the screw conveyor to transport sludge upwards at a small angle, sometimes the screw conveyor is installed in an inclined manner to facilitate Transport sludge from low to high. Therefore, the sludge after a certain dehydration process can be transferred to the next process through the screw conveyor; in the long conveying stroke of the sludge, due to the small angle of the conveyor, under the action of gravity, it also has The sludge with a certain moisture content will gradually ooze a small amount of water and flow back to the input end of the sludge, that is, the lower end of the screw conveyor; if the back seepag...
