Abstract

The invention aims at providing a two-section type sludge dewatering facility with a good dewatering effect.The two-section type sludge dewatering facility comprises a horizontally-arranged outer shell with a sealed side wall.An inner tube with a water-permeable side wall is horizontally arranged in the outer shell.Two augers formed by stirring shafts and spirally-ascending stirring blades arranged on the outer wall faces of the stirring shafts are arranged in the inner tube in a spaced mode.The stirring shafts are driven by external force to rotate.The outer shell is provided with a water drain opening, one end of the inner tube is provided with a sludge inlet for supplying sludge materials to the stirring blades.A sludge drain opening matched with the top ends of the stirring blades is formed in the outer shell.The two-section type sludge dewatering facility is characterized in that an expansion chamber is formed at the position, between the two augers, of the inner tube, and the diameter of the expansion chamber is larger than that of the inner tube.An auxiliary auger driven by an auxiliary driving mechanism is vertically arranged in the expansion chamber.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a sludge dehydrator. Background technique [0002] The invention of patent No. 200810234499.7 discloses a sludge dewatering machine, which includes an outer shell with a closed side wall, an inner tube body with a water-permeable side wall is arranged in the outer shell body, and a stirring shaft and an outer shell of the stirring shaft are arranged in the inner tube body. The wall is provided with an auger formed by spirally rising stirring blades. The stirring shaft is driven to rotate by external force. There is a drain port on the outer shell, and the inner pipe body has a sludge feed port for supplying sludge materials to the stirring blades. A sludge discharge opening matched with the top end of the stirring blade is provided, and a brush is provided on the outer edge of the stirring blade, and the bristles of the brush contact the inner wall su...
