SLUDGE DRYING MACHINE CHANGINT TYPE PADDLE

摘要

PURPOSE: A sludge dryer equipped with replaceable paddles is provided to only replace division factors on external side which are locally worn out on the outer periphery of a peddle and to simplify maintenance of the transport unit and to improve manageability. CONSTITUTION: A sludge dryer comprises a hollow body part and one or more transport units. The hollow body part provides a sealed drying space. Paddles (130), which are arranged in spiral shape by making a pair, are attached to a rotary shaft and provide heat source and discharge dried materials by forcibly transporting the dried materials and consecutively performing moisture reduction processes. The sludge dryer comprises external dividing factors (134) and inner dividing factors (132). The inner dividing factors divide the paddles into inside and outside from a circumferential direction around a rotary shaft and welded with the rotary shaft. The external dividing factors are detachably combined by using the inner dividing factors and fastening elements (133).
