Abstract

The invention relates to the technical field of sludge treatment equipment and provides sludge drying equipment. The sludge drying equipment comprises a double-screw sludge pump, a filter press and a sludge conveyor, wherein the double-screw sludge pump is used for pumping crude sludge; the filter press is connected with the double-screw sludge pump and is used for mechanically dewatering the crude sludge; the sludge conveyor is connected with the filter press and is used for pushing the mechanically dewatered sludge; a sludge turning machine is correspondingly arranged at the output port of the sludge conveyor and is used for tiling and turning the sludge; the sludge turning machine is arranged in a sealed glass greenhouse; the glass greenhouse comprises a greenhouse body and a heating floor; a turbulence fan and a ventilation opening which corresponds to the turbulence fan are arranged on the greenhouse body; multiple groups of heating pipelines are arranged in the heating floor; and each group of heating pipelines is communicated with a heat supply source. The sludge is dried in a mode of supplying heat by virtue of solar energy and the heating floor, the cost is low, the sludge drying operation is performed in the sealed glass greenhouse, and the sludge drying equipment is safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment equipment, in particular to sludge drying equipment. Background technique [0002] With the improvement of my country's sewage treatment capacity, sludge production has increased significantly. By the end of June 2012, 3,243 sewage treatment plants have been built in cities and counties with a daily treatment capacity of 1.15m 3 , based on an average of 6 tons of sludge (water content 80%) for every 10,000 tons of sewage treated, based on the actual sewage treatment volume, the national urban sewage treatment plants produce about 22 million tons of sludge every year. The environmental pollution of sludge is well known. Sludge contains a large number of pathogenic bacteria and parasites, heavy metals, salts, and toxic and harmful substances that are difficult to degrade. These substances may cause great harm to the environment, human and animal health. On the other hand, sludge is also a ...
