Abstract

The utility model relates to a liquid feeding acceleration mechanism for a centrifuge, in particular to a liquid feeding acceleration device for a horizontal spiral unloading sedimentation centrifuge, belonging to the centrifuge separation technology and equipment. The liquid feeding acceleration mechanism is composed of a revolving drum and spiral propeller blades, wherein a conical shunting block is welded in the center of a base plate, a group of blades are welded on the base plate on the periphery of the shunting block, so that the revolving speed of the incoming liquid for the centrifuge can be improved to ensure that the liquid can be fully separated from the solid during the treatment process of the centrifuge, the treatment effect is obvious, and the treatment capacity is increased.

Description

A kind of centrifuge feed liquor acceleration mechanism

Technical field

The utility model relates to a kind of centrifuge feed liquor acceleration mechanism, belongs to centrifugal separation technology equipment, particularly relates to the feed liquor accelerator technical field of using on a kind of horizontal spiral discharge sedimentation centrifuge.

Background technology

Horizontal spiral discharge sedimentation centrifuge is by rotary drum and spiral propeller blade, the liquid that contains solid phase enters centrifuge by feed tube under the effect of feeding pump, liquid rotates gradually under the drive of bowl that rotates at a high speed and spiral propeller blade, under centrifugal action, heavier solid formation is deposited on and forms the sediment layer on the rotatory drum wall in the liquid, spiral propeller continuously is pushed into rotary drum awl end with the solid formation of deposition, outside slag-drip opening discharge machine; Liquid phase thing lighter in the liquid then forms the internal layer pendular ring, overflow rotary drum continuously by the big end overfall of rotary drum, outside leakage fluid dram discharge machine, the major defect that exists is when the feed liquor amount is big, the flow velocity of liquid in rotary drum accelerated, the time of staying shortens, cause liquid also not to be accelerated to maximum (top) speed, just discharge from overfall, the time of staying shortens, and causes liquid also not to be accelerated to maximum (top) speed, just discharge from overfall, also contain a large amount of solid phases in the liquid of overflow, greatly reduce the separating effect of centrifuge, limited the performance of centrifuge processing ability.

Summary of the invention

The defective that centrifuge separates weak effect in the purpose of this utility model customer service prior art when the feed liquor amount is big, design and a kind ofly can strengthen centrifuge feed liquor liquid in rotation speed rapidly, improve centrifuge solid-liquid separation effect, increase the centrifuge feed liquor acceleration mechanism of the treating capacity of centrifuge.

The utility model is made up of substrate, rotary drum and spiral propeller blade, is welded with conical branching block in the centre of substrate, is welded with one group of blade on the substrate of branching block periphery.

The utility model can improve the rotary speed of centrifuge feed liquor liquid, makes liquid can access sufficient Separation of Solid and Liquid in the processing procedure of centrifuge, and treatment effect is obvious, and treating capacity increases.

The specific embodiment

A kind of centrifuge feed liquor acceleration mechanism pushes away robot blade 5 by substrate 1, rotary drum 4 and spiral and forms, and the centre of substrate 1 is welded with conical branching block 3, is welded with one group of blade 2. on the substrate 1 of branching block 3 peripheries

The course of work of the present utility model is: after entering centrifuge by feed tube 6 under the effect of the liquid that contains solid phase at feeding pump, after branching block 3 shuntings, enter space between substrate 1 blade 2 from the liquid of feed tube 6, liquid under the promotion of blade 2 along with rotating blades 2 rotates, simultaneously because action of centrifugal force, liquid is done radial motion by blade 2 centers to outer rim, after making the liquid that enters centrifuge obtain energy, the outer rim of leaving blade 2 with high rotational speed enters the runner that is surrounded by spiral propeller blade 5 and rotary drum 4, thereby improve the rotary speed of feed liquor liquid, make liquid in the processing procedure of centrifuge, can obtain sufficient Separation of Solid and Liquid, treatment effect is obvious, and treating capacity increases.

Claims (1)

1. centrifuge feed liquor acceleration mechanism, form by substrate (1), rotary drum (4) and spiral propeller blade (5), it is characterized in that: the centre of substrate (1) is welded with conical branching block (3), and the substrate (1) peripheral at branching block (3) is welded with one group of blade (2).
