Sludge dewatering screw press use advantages and uniform force

- Apr 11, 2018-

The sludge dewatering screw press has an outer shell with a closed side wall when in use, an inner tube body having a water-permeable side wall is provided in the outer shell, an agitation shaft and an outer surface of the agitator shaft are set in the inner tube body to set spirally upward stirring The dragon formed by the leaves, the sludge dewatering screw press is mainly driven by an agitator shaft and rotated by an external force.

The outer shell of the sludge dewatering screw press has a water outlet, and the inner tube body has a sludge feed port for supplying sludge material to the agitating blade, and a sludge discharge port matched with the top end of the agitating blade is arranged on the outer shell body. The utility model is characterized in that the inner diameter of the inner tube body is gradually reduced from the sludge feed port side to the sludge discharge mouth side, and the inner side of the inner tube body is provided with a protruding auxiliary pressure plate, and an ultrasonic wave is generated in the pressure plate. Device.

During the process of rotating the stirring shaft of the sludge dewatering screw press, it will effectively drive the stirring leaves to rotate synchronously, and the sludge will be conveyed along the stirring leaf directly from the side of the sludge feed port to the side of the sludge discharge port. As the operation progresses, the plunger is continuously thickened.

Sludge dewatering screw press in the process of sludge dewatering, the sludge volume on the side of the sludge feed port is larger, the internal pipe body inside here is also larger, the side of the sludge discharge port The sludge is initially compressed, the volume of the entire equipment is small, and the inner diameter of the inner tube is also small.

Therefore, the sludge on the side of the sludge inlet and the side of the sludge outlet are in equal contact with the stirring blade, so that during the process of compression and dehydration, the sludge applied to both sides of the agitator shaft exerts almost the same force on it. The same, that is, the uniform force of the agitator shaft increases the service life.
