Description
Technical field
The present invention relates to the wet screening technology in Mineral Processing Industry, especially a kind of use for laboratory waterpower spiral screen and waterpower
Spiral screen system.
Background technology
Vibratory sieve is often used during screening materials carrying in laboratory, when material particular diameter is smaller, vibratory sieve can not be played very well
Sieving actoion, now need hand-held screen cloth to be vibrated in water.When handling material using vibratory sieve, it is impossible to work continuously and noise
Greatly, screening efficiency is low, and when hand-held screen cloth vibrates in water, efficiency is low, loses time.
The content of the invention
It is an object of the invention to the shortcoming for overcoming prior art, there is provided a kind of use for laboratory waterpower spiral screen, structure letter
It is single, it can work continuously, screening efficiency is high.
To achieve these goals, the use for laboratory waterpower spiral screen designed by the present invention, it is characterised in that：Including upper end

So that the cylinder is divided into several chambers, sieve aperture is offered on each screen cloth, the sieve aperture on each described screen cloth
Aperture increases successively from the inside to the outside, and the bottom of each chamber offers the discharging being connected with the discharge nozzle respectively
Mouthful.
By above technical scheme, the inwall of the inwall of the feed pipe and the cylinder is tangent.
By above technical scheme, the spacing between two neighboring screen cloth is equal.
By above technical scheme, the top half of the cylinder is cylindrical, and the latter half of the cylinder is in from up to
It is coniform that lower diameter is gradually reduced.
By above technical scheme, some enclose for fixing the screen cloth lower end is formed with the inwall of the coniform cylinder
The first clamping ring, be formed with some the second clamping rings enclosed for fixing the screen cloth upper end in the lid.
By above technical scheme, the first clamping ring projection annular in shape, the upper end of the first clamping ring offer with
The first ring-type neck that the screen cloth coordinates；The second clamping ring projection annular in shape, the lower end of the second clamping ring is opened up
There is the second ring-type neck coordinated with the screen cloth.
By above technical scheme, the bottom of each chamber offers at least one discharging opening.
By above technical scheme, first switch valve is respectively arranged with each described discharge nozzle.
By above technical scheme, the upper end of the lid is provided with handle.
During hydrocyclone normal work, general principles are as follows：Ore pulp enters cylinder by feed pipe, same inside cyclone
Shi Fasheng radial motions and axial movement.As larger, the heavier particle of radial motion is moved to cylinder edge；It is smaller, lighter
Particle moved to body centre.As larger, the heavier particle of axial movement is moved down is discharged by sand setting nozzle；It is smaller, compared with
Light particle upwards by overflow pipe discharged by motion, so as to reach classification purpose.When ore pulp enters cylinder, circumference occurs in cylinder
Motion, while driving mineral grain to move in a circle, in the effect particle rearrangement of centrifugal force, wherein larger, heavier
Grain is moved to cylinder edge, because its centrifugal force being subject to is larger, therefore the radius moved in a circle is larger；It is smaller, compared with
Light distribution of particles is at center, because its centrifugal force being subject to is smaller, therefore the radius moved in a circle is smaller.In gravity
Under effect, larger, heavier particle is moved downward, by sand setting nozzle, and vortex is whirled up stream in the presence of cone wall, and
And motion upwards under pressure, drive particulate grade particles to be discharged by overflow pipe.
Prior art is contrasted, beneficial features of the invention are：The use for laboratory waterpower spiral screen, is provided with several coaxial
Sieve aperture is smaller centered on the screen cloth arranged vertically, and slot size arrangement mode, and surrounding sieve aperture is larger, and this arrangement is preferable
The radial motion for having used Different Size Fractions in hydrocyclone, each grade particle during rearranging pass through sieve
Net, larger particle is in surrounding, and less particle is moved to center, and the valve set by screen cloth lower ends at different levels is discharged,
Reach classification purpose.The material of same diameter is sized in same chamber, and exports collection, knot by respective discharge nozzle
Structure is simple, can work continuously, and screening efficiency is high.
Present invention also offers a kind of waterpower spiral screen system, its difference is：It includes the batch mixing of upper end open
Pond and above-mentioned use for laboratory waterpower spiral screen, the bottom in the batch mixing pond are offered and the use for laboratory waterpower spiral screen
Feed pipe connection discharge gate, batch mixing pond to use for laboratory waterpower spiral screen direction is provided with suction on the feed pipe
Expect pump and second switch valve.
By above technical scheme, it also includes the feed back pipe of connection batch mixing pond and feed pipe, and the feed back pipe is located at described
Between charging absorption pump and second switch valve, the 3rd switch valve is provided with the feed back pipe.
Prior art is contrasted, beneficial features of the invention are：The waterpower spiral screen system, is provided with several ring rings and is nested
Screen cloth, using the effect screening materials carrying step by step of current centrifugal force, the material of same diameter is sized in same chamber,
And collection is exported by respective discharge nozzle, and it is simple in construction, it can work continuously, screening efficiency is high.
