Circumferential acceleration type material issuing chamber for horizontal screw centrifugal machine

Abstract

The invention discloses a circumferential acceleration type material issuing chamber for a horizontal screw centrifugal machine. The circumferential acceleration type material issuing chamber for the horizontal screw centrifugal machine is characterized in that a material issuing chamber body is fixedly arranged in a hollow shaft of a spiral conveyor and rotates along with a spiral conveying shaft; the material issuing chamber comprises a first conical cavity, first-stage blades, a second conical cavity and second-stage blades, wherein the small end face of the first conical cavity is of a convex circular structure, the convex circle of the small end face of the first conical cavity faces an outlet of the feeding pipe, the first-stage blades are uniformly welded on the conical surface of the first conical cavity in the circumferential direction, inlet edges of the first-stage blades are flush with the outlet plane of the feeding pipe, and outlet edges of the first-stage blades are flush with the large end face of the first conical cavity; the large end face of the second conical cavity faces the large end face of the first conical cavity, the feeding pipe penetrates through the center of the small end face of the second conical cavity, the second-stage blades are uniformly welded between the large end face of the first conical cavity and the large end face of the second conical cavity in the circumferential direction, and the first conical cavity, the first-stage blades, the second conical cavity, the second-stage blades coincide with the axis of the feeding pipe. According to the circumferential acceleration type material issuing chamber, the separation efficiency of the horizontal screw centrifuge is improved.

Description

technical field [0001] The invention belongs to the field of centrifuges, and in particular relates to a circumferentially accelerating material distribution chamber for a decanter centrifuge. Background technique [0002] Considering the particularity of axial feeding and double rotor structure, the decanter centrifuge needs to set a material distribution chamber in the inner cavity of the screw conveying shaft as a transition zone between the material from the feed pipe to the drum separation chamber. Most of the material distribution chambers of decanter centrifuges on the market are simple cylindrical chambers with discharge holes. The process of the material to be separated entering the rotating material distribution chamber from the stationary feed pipe is mostly concentrated flow or jet flow, and The transition without flow guide device leads to the disordered flow of materials in the material distribution chamber, which not only wastes most of the energy required for...
