Screw type mud dehydration plant

Abstract

The invention relates to a screw type sludge dewatering device. When the fixed plate and the movable plate are damaged, it is convenient to repair and replace the plate, and the waste of raw materials can be reduced to the greatest extent, so that the manufacturing cost can be reduced. A plurality of fixed plates and movable plates are inserted on each shaft inside the shell, and a screw is inserted into the space in the fixed plate and the movable plate, and the sludge supplied from one side of the shell is passed through the rotational force of the above screw. , is squeezed and moved to one side, so as to achieve the purpose of dehydration. The screw type sludge dewatering device is characterized in that: the fixed plate and the movable plate are sheet-shaped, and each two are a pair, which are inserted into the To the fixed plate shaft and the floating plate shaft and form a combination, so that a circular space for setting the screw rod is formed inside; the above-mentioned floating plate shafts are respectively provided with eccentric shafts, so that the floating plate shafts can be inserted The swimming plate in the center performs linear motion up and down. When the fixed plate or the movable plate is damaged, it is only necessary to remove the shaft to which the damaged plate belongs.

Description

Technical field [0001] The present invention relates to a rotary sludge dewatering device, especially when the fixed plate and the moving plate provided on the dewatering device are damaged, the damaged plate can be easily repaired and replaced, and the fixed plate and the moving plate can be minimized An expensive rotary sludge dewatering device. Background technique [0002] In order to protect the environment, the waste sludge generated in various wastewater treatment plants is dehydrated into solids by dehydration devices. The dehydration devices used are filter press or belt press dehydration devices. Generally, the sludge is transported in filter bags and dewatered by pressurizing rollers during transport. The above-mentioned filter press / belt press type dehydration device often causes the filter bag mesh to be blocked, so the dehydration efficiency is low, and the dehydration operation requires various additional equipment. The equipment is a large-scale device, which requ...

Problems solved by technology

However, when one of the many fixed plates 102 or movable plates 104 installed is damaged, it is necessary to take out a plurality of shafts installed on the casing 100 along the axial direction, and simultaneously disassemble and take out the screw, so as to repair the damaged plate. Carry out maintenance and replacement, which takes a lot of time to disassemble and assemble, resulting in reduced sludge treatment efficiency

[0007] In addition, in order to form a small gap S between the fixed plate 102 and the movable plate 104, it is necessary to insert a spacer (Spacer) 109 on the inner surface of the fixed plate 102, resulting in a complicated structure, and it is also difficult for the fixed plate 102 and the movable plate. When 104 is cut and manufactured, because the circular space portion provided with the screw 130 occupies a large area, the consumption of raw materials during processing is large, resulting in an increase in the manufacturing cost of the dehydration device
