Abstract

The invention relates to the technical field of solid waste processing devices, and relates to a sludge reduction device which comprises a shell, a feed port in the upper side of the shell, and a discharge port in the lower side of the shell. A conveying belt is arranged at the position, located on the lower side of the feed port, in the shell. The conveying belt comprises a plurality of hollow pipes and hinges which are alternately arranged in parallel. Thermal medium boxes are arranged on the inner wall of the shell. The two thermal medium boxes are provided with a first inlet pipe and a first outlet pipe respectively. Rails are arranged on the side walls of the thermal medium boxes. The hollow pipes are arranged on the rails. The thermal medium boxes are provided with driving assembliesfor driving the hollow pipes to move. The top wall of the shell is provided with a suction structure. The sludge reduction device has the advantages that a thermal medium is introduced into the thermal medium boxes through the first inlet pipe, heat is transmitted between the hollow pipes and the sludge when the hollow pipes convey the sludge, and the effect of evaporating sludge water is achieved; by means of the device, heating and dewatering can be conducted on the sludge through a low-grade heat source, and the sludge reduction processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment equipment, in particular to a sludge reduction device. Background technique [0002] Sludge is a product in the sewage treatment process. It is a solid, semi-solid and liquid waste. Its amount accounts for about 0.3%~0.5% of the sewage treatment volume. In addition to containing ash and a large amount of water (95%~ 99%), it also contains a large amount of organic matter, pathogenic microorganisms, bacteria, parasite eggs, volatile substances, heavy metals, salts, and plant nutrients (nitrogen, phosphorus, potassium), etc. It is bulky, perishable, and easily causes secondary pollution. [0003] At present, production enterprises generally transport the sludge out after initial dehydration. The Chinese invention patent with the publication number CN107586002A discloses a sludge drying treatment device, which includes a drying pipe body, two supports supporting the drying pipe body, ...
