Abstract
The invention provides a horizontal screw centrifuge. The horizontal screw centrifuge comprises spirals, a drum, a hood and a differential mechanism. The spirals are installed inside the drum; the hood is installed outside the drum; the spirals include a straight-section spiral and a conical-section spiral; spiral blades of the spirals comprise material pushing faces and non-material-pushing faces; tungsten carbide layers are welded to the material pushing faces; fan-shaped inclined plates of a certain height are spirally arranged between the spiral blades of the straight-section spiral. Materials enter the centrifuge from the position of a spiral middle feeding inlet to be separated; a solid-phase discharging outlet is located in one side of the conical-section spiral; a solid-phase discharging device is arranged in the position, at the solid-phase discharging outlet, of the drum and is of a mouse cage type drum structure; the differential mechanism is arranged on one side of the conical-section spiral. The solid phase can effectively and rapidly reach the inner wall of the drum through the fan-shaped inclined plate structure on the straight-section spiral; the whole device is reasonable to arrange and convenient to use and machine; the effective separation effect can be achieved, and the horizontal screw centrifuge can be further used and popularized.
Description
Technical field
The present invention relates to separation centrifuges technical field, be specifically related to a kind of horizontal screw centrifuge.
Background technology
Centrifuge utilizes centrifugal force; the machinery of each component in the mixture of separating liquid and solid particle or liquid and liquid; along with the development of industry, centrifuge is widely applied in chemical industry, oil, food, pharmacy, ore dressing, coal, water treatment and boats and ships etc.
Horizontal screw centrifuge is when working operation, the rotating speed of high strength can be produced, by differential mechanism, rotary drum is rotated with equidirectional friction speed with the spiral being arranged on rotary drum inside, spiral drives helical blade to rotate and takes away the solid-phase being deposited on drum inner wall, thus reach the state of Separation of Solid and Liquid, but horizontal screw centrifuge due to material time of staying in rotary drum not long, when making to rotate, solid phase and liquid phase fail to separate completely, make also can remain solid phase impurity component in last liquid phase, do not reach effective separating effect.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of horizontal screw centrifuge, spiral arranges swash plate structure, can effectively be separated solid phase and liquid phase, improve separative efficiency.
For realizing above object, the present invention is achieved by the following technical programs:
A kind of horizontal screw centrifuge, comprise spiral, rotary drum, hood and differential mechanism, spiral is installed in described rotary drum inside, hood is installed in rotary drum outside, described spiral is divided into straight section spiral and cone section spiral, the helical blade of spiral comprises pusher face and non-pusher face, pusher face is welded with carbide layers, between the helical blade of straight section spiral, spiral is provided with the fan-shaped swash plate of certain altitude, material enters centrifuge inside by spiral intermediate feed mouth position and is separated, solid phase discharging opening is positioned at the side of cone section spiral, the rotary drum of described solid phase discharge outlet is provided with solid phase drawing mechanism, solid phase drawing mechanism is squirrel-cage barrel configuration, differential mechanism is arranged at the side of cone section spiral.
Preferably, described helical blade pusher face carbide layers thickness is 2-3mm.
Preferably, the low 3-5cm of height of the aspect ratio helical blade of described fan-shaped swash plate.
Preferably, described straight section spiral side is provided with liquid phase overfall near gating location.
The invention provides a kind of horizontal screw centrifuge, because spiral is in the process of pusher, rotating speed is very fast, solid phase is often caused not to be fully formed precipitation, namely in straight section spiral material sedimentation period, spiral fan shaped swash plate is increased between the helical blade of spiral, rotary drum and spiral rotating time, when material solid phase flow process is by fan-shaped swash plate, produce certain push effect, make the material of solid phase can arrive drum inner wall fast, pass through auger again, helical blade scrapes the deposit being deposited on drum inner wall, solid phase is from solid phase discharge hole for discharge, effectively raise the separative efficiency of centrifuge.Helical blade pusher face is welded with carbide layers, effectively can improves the scuff resistance of helical blade.Solid phase drawing mechanism is squirrel-cage barrel configuration, is also conducive to solid phase discharging, prevents from causing wearing and tearing to rotary drum during solid phase discharging, and whole device is arranged rationally, uses easy to process, and can reach effective separating effect, can use by further genralrlization.
