Problems solved by technology

Due to the defects of its structure, the current centrifuge adopts straight pipes for the clear liquid mouth section. The centrifuge in this way will keep the water content above 32% (the material is inorganic) or 82% when the material is slag discharged. % or more (the material is organic matter), the moisture content cannot be reduced, which will cause troubles in transportation and storage of slag materials, which is not conducive to the efficient, safe and low moisture content treatment of materials

Abstract

The invention discloses a high-dryness horizontal screw centrifuge. The high-dryness horizontal screw centrifuge comprises a housing, wherein a rotary drum is rotationally connected in the housing; the rotary drum is rotationally connected with a spiral propeller having a speed difference with the rotation of the rotary drum; the rotary drum comprises a pipe fitting and a second conical pipe; thespiral propeller comprises a cylinder; a first spiral propelling blade and a second spiral propelling blade are fixed on the cylinder; the outer contour of the second spiral propelling blade is conical, and is consistent with the taper of the second conical pipe; the cylinder is provided with a cavity positioned between the first spiral propelling blade and the second spiral propelling blade; thecavity is provided with a material inlet formed in the cylinder; a material introducing pipe is arranged in the cylinder; a feed outlet positioned in the cavity is formed in the inner end of the material introducing pipe; and the taper of the pipe fitting is 0.1-10 degrees. The high-dryness horizontal screw centrifuge is skillful and reasonable in structural design, can greatly improve the drynessof materials, and deserves popularization and application.

Description

technical field [0001] The invention relates to a device, in particular to a high-dryness decanter centrifuge. Background technique [0002] The decanter centrifuge is a horizontal spiral unloading, continuous operation settling equipment, which has been widely used in solid waste dehydration in municipal sludge dewatering, water plant sludge dewatering, industrial and agricultural wastewater treatment, petrochemical, food, pharmaceutical and other industries. liquid separation and dehydration. Its working principle is: the drum and the screw feeder rotate at a high speed in the same direction at a certain differential speed, and the material is continuously introduced into the inner cylinder of the screw feeder from the feeding pipe and then enters the drum after being accelerated. Under the action of centrifugal force, the heavier solid The phase matter deposits on the drum wall to form a sediment layer, and the screw pusher continuously pushes the deposited solid phase m...
