Technical Field

The utility model relates to the technical field of sludge treatment, in particular to a sludge dehydration and drying device.

Background technique

Sludge dehydration and drying is based on sludge reduction. Through deep dehydration and drying equipment, the moisture content of sludge is reduced to achieve sludge reduction.

In the prior art, the sedimentation sludge not only has a low concentration of only 1-2wt.%, but is also difficult to dehydrate. Therefore, the dehydration process requires a large amount of dehydration equipment, which not only requires a large investment in equipment, but also occupies land. In addition, the moisture content of the sludge after dehydration is high, reaching 75-80wt.%, and the sludge volume is large. The annual sludge production reaches more than 30 million tons, which requires a large amount of land for landfill. The sludge contains harmful bacteria, which will cause secondary pollution after landfill. The underground pollution caused by this landfill is difficult to repair, and the sludge needs to be further dried. The existing sludge treatment equipment generally only has dehydration or drying functions, and cannot achieve continuous or deep dehydration and drying of sludge in one device. It requires a lot of manpower and material resources and has a high sludge treatment cost.

Furthermore, a spiral stirring blade is arranged on the rotating shaft.

Furthermore, an extension plate is extended upward from the right vertical plate of the U-shaped base, a screw conveyor is embedded on the extension plate, and a discharge port of the screw conveyor is arranged directly above the inlet of the feed hopper.

Furthermore, a discharge hopper is connected to the middle part of the lower surface of the dehydration and drying bin, a first solenoid valve is provided at the feed port of the discharge hopper, an air outlet pipe is connected to the upper end of the left side surface of the dehydration and drying bin, a second solenoid valve is provided at the air inlet end of the air outlet pipe, and a temperature and humidity sensor is provided at the lower end of the left side surface of the dehydration and drying bin.

The beneficial effects of the utility model are as follows: the utility model adds a dehydration and drying bin and a heating tube to the device, which can realize the dehydration and drying of sludge, and can reduce the weight of the sludge into granular form, and become ash after drying. The ash is deeply processed into fuel rods or smokeless carbon. The utility model is well made, has stable performance, advanced technology, high output, low energy consumption, high degree of mechanization, low investment and the like.
