Horizontal screw discharge sedimentation centrifuge and its feed tube

Abstract

The invention discloses a feeding pipe barrel of a horizontal spiral discharge sedimentary centrifuge. The feeding pipe barrel comprises a barrel body. A plurality of discharge openings are formed in the barrel body and are in a streamline shape. All the discharge openings are distributed in a spiral mode. The invention further discloses the horizontal spiral discharge sedimentary centrifuge. The horizontal spiral discharge sedimentary centrifuge comprises a straight drum, a conical drum and a spiral body, wherein the conical drum is installed at one end of the straight drum, and the spiral body is arranged inside the conical drum. Spiral blades are arranged on the peripheral wall of the spiral body. A feeding pipe is arranged inside the spiral body. The feeding pipe barrel communicated with the feeding pipe is arranged inside the spiral body. The disturbance influence formed by fluid on a sedimentary separation area during suspension liquid discharging can be effectively reduced, and the centrifugal separation effect is improved.

Description

technical field [0001] The invention belongs to the technical field of centrifugation and separation equipment, and in particular relates to a horizontal spiral unloading sedimentation centrifuge and a feeding pipe cylinder. Background technique [0002] When the decanter centrifuge centrifuges the suspension, the material enters the feed tube cylinder from the feed pipe, and with the high-speed rotation of the drum, the suspension is centrifugally accelerated from the five outlets, and the material is discharged quickly. . At present, the shape of the discharge port of the feed tube body is designed to be a perfect circle, and the suspension is discharged straight from the perfect circular discharge port. Although it can meet the requirements of the discharge to a certain extent, it will cause problems. The discharge area in the liquid pool is undergoing the process of sedimentation and separation to form deflection, which causes different degrees of turbulent flow and aff...

Problems solved by technology

At present, the shape of the discharge port of the feed tube body is designed to be a perfect circle, and the suspension is discharged straight from the perfect circular discharge port. Although it can meet the requirements of the discharge to a certain extent, it will cause problems. The discharge area in the liquid pool is undergoing the process of sedimentation and separation to form deflection, which causes different degrees of turbulent flow and affects the effect of centrifugal separation.
