Abstract

The invention provides a belt-type sludge drying device. The belt-type sludge drying device comprises a banded extruder, a spiral distributing device, a conveyer, a drying bin and a drying machine; an input end of the banded extruder is used for introducing the sludge, an output terminal of the banded extruder is connected with the input terminal of the spiral distributing device, the conveyer comprises an upper layer conveying unit and a lower layer conveying unit, the upper layer conveying unit comprises a first driving motor, a first active sprocket wheel, a first driven sprocket and a first conveyor belt, the conveyer of the belt-type sludge drying device is composed of the upper layer conveying unit and the lower layer conveying unit, the dehydrated sludge is in the drying bin, temperature in the drying bin is increased to a set value by the dried gas, the noodle-shaped sludge flows from the upper layer conveying unit to the lower layer conveying unit, moisture in the sludge is taken away by hot air, and a purpose of full drying is achieved. The belt-type sludge drying device can fully take moisture in the sludge away, and the drying degree is high.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a belt sludge drying system. Background technique [0002] With the expansion of sewage treatment scale and the improvement of standards, the amount of sludge generated continues to increase. In addition to the sludge accumulated in the past, China's sludge treatment and disposal has become a major issue in the field of sewage treatment. [0003] The moisture content of the sludge generated from the sewage treatment plant is very high, generally >80%. The sludge must be dried first to facilitate further disposal. At present, the main technical routes of sludge drying include thermal drying, mechanical drying, air drying, and solar drying. Mechanical drying can often only dry sludge to a moisture content of about 65%, while air drying is less efficient. The effect of simply applying a technical means is not satisfactory. Contents of the invention [0004] The tech...
