Internal runner structure of butterfly type centrifuge

Abstract

The invention provides an internal runner structure of a butterfly type centrifuge. The internal runner structure comprises a feeding pipe, a centrifugal drum, a heavy liquid centripetal pump, a separating area disc, a light liquid discharging pipe, and a heavy liquid discharging pipe, and further comprises a top end disc and a feeding distributing disc, wherein the feeding distributing disc is arranged above the separating area disc; the top end disc is arranged above the feeding distributing disc; a feeding clearance is formed between the top end disc and one side of the feeding distributing disc; the feeding pipe is communicated with the feeding clearance; a heavy liquid clearance is formed between the top end disc and the inner wall of the centrifugal drum; the heavy liquid centrifugal pump is communicated with the heavy liquid clearance; the heavy liquid centrifugal pump is connected with the heavy liquid discharging pipe; the light liquid discharging pipe is arranged below the separating area disc. The internal runner structure has the advantages that solid, light liquid and heavy liquid are separated in the separating area; the light liquid discharging pipe and the heavy liquid discharging pipe are positioned at different positions; the separated liquid cannot meet with mixed liquid to form turbulent flow, and the separating effect is good; light liquid is drained by a rotating force of the centrifugal machine, so that a light liquid centrifugal pump is eliminated. The internal runner structure is simple in structure and high in liquid draining speed.

Description

technical field [0001] The invention relates to a centrifuge, in particular to an internal channel structure of a butterfly centrifuge for liquid-liquid-solid separation. Background technique [0002] The disc centrifuge can quickly and continuously separate solid-liquid and liquid. It is a kind of vertical centrifuge and is widely used in industrial production. [0003] At present, the main disc centrifuge structure is the following two: [0004] 1. Butterfly centrifuge with bidirectional heart pump structure [0005] figure 2 Structural diagram of a butterfly centrifuge with a bidirectional heart pump structure. [0006] Such as figure 2 As shown, the butterfly centrifuge with bidirectional heart pump structure has an inlet A, a light liquid outlet B and a heavy liquid outlet C. The centrifuge adopts the structural design of a bidirectional heart pump. The liquid feed and separated light phase and heavy phase liquid all enter and leave from the upper part of the centr...
