Abstract

The invention relates to the technical field of solid-waste treatment equipment, and relates to a sludge reducing device. The sludge reducing device comprises a shell, a feeding port formed in the upper side of the shell and a discharging port formed in the lower side of the shell. A conveying belt is arranged at the position, located on the lower side of the feeding port, in the shell and comprises a plurality of hollow pipes and hinges which are arranged in parallel at intervals, thermal medium boxes are arranged on the inner wall of the shell, and a first inlet pipe and a first outlet pipeare mounted on the two thermal medium boxes respectively. Rails are arranged on the side wall of the thermal medium boxes, the hollow pipes are arranged on the rails, driving assemblies for driving the hollow pipes to move are arranged on the thermal medium boxes, and an air extracting structure is arranged on the top wall of the shell. The sludge reducing device has the advantages that a thermalmedium is introduced into the thermal medium boxes through the first inlet pipe, the hollow pipes carry out indirect heat transfer with sludge while conveying the sludge, the function of evaporating sludge moisture is achieved, thermal dehydration can be carried out on the sludge through a low-grade heat source, and the treatment of sludge reducing 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, ...
