Description
Technical field
The present invention relates to a kind of vibratory sieve and permanent-magnet separator combined separation device.
Background technology
Machinery is thrown blast cleaning surface scale technology and is widely used, in ball sand（For example after Shot Blasting produce ball with
The mixture of oxide skin）Separation aspect, at present by the ball sand separation system constituted using vibratory sieve and permanent magnet cylinder, but because
The restriction of the conveying capacity for the treatment of capacity sieve vibrated, causes the ball sand treating capacity can not be while improving with treatment effect；Screen angle
It is one of characterisitic parameter of vibratory sieve, while being also one of decisive factor of vibratory sieve conveying capacity, increases screen angle, accelerates
The transporting velocity of vibratory sieve, so as to improve the conveying capacity of vibratory sieve, but screening quality is poor.
Chinese patent literature CN205270726U discloses the automatic separating apparatus of a kind of casting sand and shot, although no
It is same as throwing the ball sand separation after blast cleaning, but has certain reference value.Its general principle is to first pass through sieved through sieve, is utilized
Shot is different from molding sand grain diameter and carry out initial gross separation, then again by electromagnet by particle diameter in the mixture after sieving compared with
Little shot is absorbed.This structure is not particularly suited for ball sand separation, and the particle diameter of the shot in one side pill-sand mixture is not
Certain bigger than iron filings, screening cannot realize required initial gross separation.And can not enter one after a certain amount of shot of electromagnet absorption
Step absorption, accordingly, it would be desirable to a period of time, clears up once by electromagnet（The 9th section of patent document specification-remove electromagnet
Under the conditions of）The shot of absorption, it is difficult to carry out the ball sand separation of continuous high-efficient.
CN101428401A discloses a kind of pill-sand mixture after cast surface treatment separator, and it adopts many fractions
From, first metal impurities are isolated by shot-sand separator, remaining shot, sand and little metal impurities, then by hair-dryer
Dust and part sand are blown away, the remaining adsorbing separation based on electromagnet goes out shot and little metal impurities, further mistake
Sieve, isolates complete shot.Its whole equipment is extremely complex, and for some separating steps, the separation of such as dust is simultaneously
Very unnecessary, detached final purpose is to isolate shot.And its link is relatively more, mutual cooperation is in some stages
Can have problems, the use of such as triangular groove, it is impossible to complete continuous separation, cause relatively inefficient.
Similarly, Chinese patent literature CN105798781A discloses a kind of ball blast waste recovery systems, and it is also adopted by many
Level separate mode, carries out first ball sand separation, obtains pellet, then is screened, and magnetic separation is finally carried out again, its configured each
Between part in addition to supplied materials undertaking, without mutual cooperation, it appears structure compares larger, takes up room than larger.
The content of the invention

Specific embodiment
With reference to Figure of description 1, its agent structure shows as a kind of incline structure, for incline structure, upper end therein
There is clearly differentiation with lower end, especially for such as V belt translation（Band conveying）Such transmission mechanism, top and bottom refer to
Two ends on belt wheel centerline direction.
Meanwhile, incline structure, for the structure with certain scale of construction, it has clearly is managed by those skilled in the art
The upper side of solution and downside.Especially, such as vibratory sieve, its screen cloth is typically flat-surfaced screen, is fixed on support body, etc.
Effect ground has planar structure.And vibratory sieve, especially multistage vibratory sieve, what its structural texture was often in tilted layout, so as to
Concept with upper and lower side.
It will also be appreciated that being based on supplied materials direction, supplied materials（It is analogous to fluid）Upstream side be front side, after downstream is
Side.
As described in the background section, current ball sand separation generally adopts multi-stage separation, not only complex structure, Er Qieshou
The restriction of links bottleneck effect, whole efficiency is not high.
A kind of vibratory sieve as described in Fig. 1-4 and belt-type permanent-magnet separator combined separation device, it includes two substantially
Part, first permanent-magnet separator, another is vibratory sieve 2, and both coordinateds complete ball sand separation equivalent to a step.
It is the belt-type permanent-magnet separator 1 being in tilted layout with regard to the permanent-magnet separator, the belt for being used adopts flat rubber belting,
In general, belt mechanism includes frame, belt wheel and belt, frame is band wheel carrier, to provide belt wheel and belt mechanism other
The installation foundation of part.In general, being located in the circle that belt is formed with wheel carrier.Then band wheel carrier is arranged on body from side
On.In some applications, belt wheel is arranged on body using the axle for overhanging, for the belt wheel mechanism of heavy duty, such as conveying belt machine
Structure, its belt wheel should not adopt overhanging structure, but adopt the assembling structure corresponding to belt wheel two ends, in the structure shown in Fig. 3, band
Wheel shaft is supported using two ends.
Belt shaft is installed on bracing frame 1-4 shown in the figure, and the structure related to belt shaft is bend pulley 1- in figure
7th, driving drum 1-6, and belt tension cylinder and device 1-3.
Conveyer belt 1-2 in figure is belt, realizes rotating based on above-mentioned cylinder, and wherein motor drives with decelerator group 1-1
Dynamic driving drum 1-6, so that conveyer belt 1-2 motions.
With regard to band wheel carrier, can be found in the magnet apparatus for placing 1-5 shown in figure, the conveyer belt 1- of the structures shape with wheel carrier
2 basic status, visible in figure, magnet apparatus for placing 1-5 is the structure being obliquely installed, and its downside has setting section and blanking
Section, the so-called section that arranges is the band truck parts for arranging permanent magnetic iron block, it is believed that the anti-locking apparatus 1-5 of magnet is with wheel carrier
A part；And blanking Duan Ze is the part for being not provided with permanent magnetic iron block, in other words magnetic field force is not enough to overcome shot self gravitation
Part.
The separation that section is arranged with blanking section is with magnetic flux as node, rather than the set location of permanent magnet, to this this area
Technical staff it is easy to understand.
The magnetic flux of magnet, dies down as the distance apart from magnet becomes big, and in other words, produced magnetic field force will become
It is little.
Permanent magnet allows these permanent magnets to be laid in setting section, the magnetic field with some strength using the block-shaped magnet of bar
Scope, is constrained with magnetic field intensity scope, and beyond the scope, then shot is not enough to overcome its own suffered gravity.Comparatively,
Can adsorb shot in certain scope under zone face on the downside of permanent magnet distribution.Really, this kind of absorption is not zone face absorption,
But magnet adsorption, zone face is only intended to stop that shot is up, and shot is attached on zone face, so as to appear to zone face
In absorption shot, consequently, it is possible to zone face can run with shot, until the magnetic field force that permanent magnet is provided is not enough to overcome shot certainly
The gravity of body and come off from zone face.
The vibratory sieve 2 coordinated with belt-type permanent-magnet separator 2 is seen again, and its cooperation is found in aforesaid first inventive principle,
Effect of vibration and sieving actoion have simultaneously, and in addition to tiny impurity is directly screened out, the part for tailing over is based on because of vibration
Density and quality produce layering.
Specifically, the vibratory sieve 2 is the vibratory sieve 2 being obliquely installed, and on the one hand sieves, on the other hand, inclined vibration
The part tailed on sieve is layered, also can be descending along inclined compass screen surface, the part for screening out directly from below sieve nest along drop down into
Slag-drip opening 2-2.
Correspondingly, vibratory sieve 2 includes：
The main body of sieve nest 2-5, sieve nest 2-5 is a trench structure, i.e., without wainscot, it is obliquely arranged on under wheel carrier
Side.In an inclined direction, upper end is provided with charging aperture 2-1, as shown in Fig. 2 charging aperture 2-1 is funnel structure, sieve nest is accessed in lower end
2-5, for accepting the shot for being mixed with the impurity such as oxide skin.
Sieve nest 2-5 is then located at the downside of blanking section in the lower end of its incline direction, and the lower end corresponds to blanking section top
Downward slag-drip opening 2-2 is provided with, and the end for corresponding to blanking section is then provided with discharging opening 2-3；Top and end herein is obvious
Determine according to supplied materials direction.
Based on said structure, end of the part for tailing over directly from screen cloth 2-8 falls, comparatively, the end of screen cloth 2-8
Should be on front side of the top of slag-drip opening 2-2.Here front side, ibid, i.e., from the upside of the front side in supplied materials direction, i.e. incline direction.
So with regard to screen cloth 2-8, necessarily comprising the part for accepting supplied materials, the i.e. part below charging aperture 2-1, then
Extend to the front side of slag-drip opening 2-2, it is clear that the waste residue part because of the projectile produced by inertia should be avoided, on the one hand, row
Cinder notch 2-2 can with relatively large, on the other hand, the lower edge of screen cloth 2-8 i.e. as it was previously stated, slag-drip opening 2-2 tops rear side should be located at,
Or directly guide such as slag-drip opening 2-2, here, it may be considered that the cast of waste residue.Herein extend to slag-drip opening 2-2, should
It is that, based on the projectile of waste residue, screen cloth 2-8 extends to front side preset distances of the slag-drip opening 2-2 in screen cloth 2-8 incline directions.
The most important projectile for considering waste residue of the preset distance, it is impossible to more than slag-drip opening 2-2, and no more than slag-drip opening 2-2
It is greatest limit that screen cloth is extended downwardly.
Least limit is then to tail over partial hierarchical and shot to carry out detached minimum screen cloth 2-8 development lengths by magnetic force
（Length on incline direction）.
Comparatively, screen cloth 2-8 is parallel with the band section on the downside of wheel carrier, although the lower half phase of screen cloth 2-8 and chape
Separate, but it is unsuitable excessive, it is clear that and the closer to belt, then magnetic flux is bigger for screen cloth 2-8, but should also be as avoiding broken part
It is adsorbed onto on zone face（Broken part is located at relative lower floor）, based on this, design distances of the screen cloth 2-8 for lower belt surface.
Opposed flattened zone face, is conducive to the attachment of shot, belt to be affected by self gravitation, can naturally droop, lower tab
Under part, belt produces flexure, causes shot to come off, therefore, the sagging of belt should be as far as possible reduced, routinely, for band
For transmission mechanism, belt is tensioned, is conducive to maintaining belt to keep larger cornerite to belt wheel, to obtain good biography
Dynamic performance.In the structure shown in Fig. 2, belt is tensioned, zone face holding level as far as possible is made, so that the attachment of shot
It is relatively reliable, therefore in a preferred embodiment, belt-type permanent-magnet separator 1 needs to arrange belt stretcher.
In certain embodiments, tensioning apparatus is configurable to tension wheel structure, due to needing to keep the relative of lower belt surface
Level, therefore, in such tension structure, upper zone face can only be tensioned.
In certain embodiments, the tensioning apparatus is set to：The upper band wheel seat of belt-type permanent-magnet separator 1 is in belt wheel
Floating seat on heart line direction, there is provided the adjustment mechanism on the centerline direction is configured to the tensioning apparatus.Comparatively, should
In embodiment, floating structure is relative to other structures, and structure is compacter, and does not interfere with v-belt contact angle.And in previous enforcement
Example in, tensioning wheel may increase v-belt contact angle, it is also possible to reduce v-belt contact angle, be that with the inner face of band as acting surface also
It is with outside as acting surface.
Floating is the floating of belt wheel centerline direction, generally adopts track structure using band wheel carrier, there is provided in track structure
Guiding and locking on direction, you can realize locking.
With regard to structural support, two parts can be expressed as in figure, be in fact propping up to belt-type permanent magnet separator 1
Support, another is the support to vibratory sieve 2, is first being supported by rigid bracing frame for belt-type permanent-magnet separator 1, such as Fig. 2 institutes
