Abstract

The invention relates to the field of environment protection equipment, and particularly relates to a rotating extrusion type sludge dewatering machine. The sludge dewatering machine comprises a machine body, gear type spiral push shafts, a bracket, a condensate water circulating device, a drive system, an air cleaning system and an automatic temperature control system. The air cleaning system is arranged on the machine body. The two gear type spiral push shafts parallel to each other and the automatic temperature control system are arranged in the machine body. Two ends of the machine body are respectively provided with a heat conducting medium inlet and a heat conducting medium outlet, and two ends of the gear type spiral push shafts are respectively provided with a heat conducting medium inlet and a heat conducting medium outlet. The machine body is horizontally arranged on the bracket. The condensate water circulating device is arranged below the bracket. The drive system is arranged at one end of the gear type spiral push shafts. The machine achieves an integrated process of sludge drying, achieves low energy consumption and high efficiencies in the operation process, and adopts a fully-automatic operation mode without the need of a specially-assigned person for watching.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a rotary extrusion sludge dryer. Background technique [0002] In the sludge treatment process, sludge drying equipment has always had defects such as complicated operation, high cost, small processing capacity, large energy consumption, and easy to cause secondary pollution. Therefore, the market urgently needs to develop a compact structure, integrated High, stable sludge treatment effect, low energy consumption, small maintenance, fully enclosed operation, no secondary pollution sludge dryer. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a rotary extrusion sludge dryer suitable for wastewater treatment and sludge treatment, which makes wastewater treatment and sludge drying simple and easy to use, Energy saving, simple structure, easy operation and easy replacement. [0004] In ...
