A high-performance sludge dewatering and drying special equipment

Abstract

The invention belongs to the technical field of sludge treatment, and particularly relates to special high-performance sludge dewatering and drying equipment, which comprises a rack, wherein a dryingbox is fixedly connected to the rack, and one side of the drying box is higher than the other side of the drying box; a set of grooves with semicircular sections are formed in the drying box. A rotating shaft is arranged in the groove, a water hole is formed in the rotating shaft, a spiral auger is fixedly connected to the periphery of the rotating shaft, and the two ends of the rotating shaft arerotationally connected with the drying box; one end of each rotating shaft penetrates through the drying box and then is fixedly connected with a driving gear; according to the invention, heat energyconverted from clean energy is utilized and a high-temperature thermalization effect is formed; and the sludge dewatering and drying device continuously circulates in the device, namely, the sludge or substances to be dewatered and dried in the sludge are quickly dried under the continuous action of heat conduction and stirring of the water holes and the packing auger in the device and high-temperature hot water energy, so that the problem of dewatering and drying of the sludge is solved in a real sense.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment, in particular to a special equipment for dewatering and drying high-performance sludge. Background technique [0002] Sludge drying, also known as sludge dehydration, refers to the process of removing most of the water content from sludge through percolation or evaporation, and generally refers to the use of self-evaporation facilities such as sludge drying fields (beds). After the sludge is concentrated, the water content of the sludge is further reduced by physical methods, which is convenient for the transportation, accumulation, utilization or further treatment of the sludge; there are two kinds of dehydration (drying) methods: natural evaporation method and mechanical dehydration method, which are customarily called mechanical dehydration methods. The dehydration method is sludge dehydration, and the natural evaporation method is called sludge drying. Although the methods are differ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many sludge dewatering and drying equipments on the market, many of which are either only for surface disposal, unable to achieve rapid water removal let alone dry disposal; or the process is complicated, the operability is poor or the use cost is too high; or It is to achieve dehydration and drying through the most primitive way of relying on the weather: drying in the sun. This method is not to mention the use of the site area, which is greatly affected by the weather and the cycle time is long.
