Description
The utility model belongs to the gravity separation technical field, is a kind of shaking table equipment that improves micro-size fraction mineral disposal ability.
Classify from the gravity treatment principle, the utility model shaking table belongs to laminar shear type gravitational separation equipment.In practical gravity treatment technology, laminar shear type shaking table is a kind of important means that realizes the high sharpness of separation of fine-particle minerals, the contradiction of following high sharpness of separation to produce then is that single device mineral disposal ability is low excessively, and therefore, laminar shear type shaking table does not obtain wide model at home and abroad always and uses.At present, industrial shaking table all is that the mineral disposal ability is bigger absolutely almost, the Turbulent Flow Type shaking table that sharpness of separation waits to improve.The annular shaking table of the utility model makes it on the laminar shear type basis that keeps high sharpness of separation owing to have unique texture, and single device mineral disposal ability reaches the growth of several times and even tens of times.Mine ore dressing factory adopts the rate of recovery that this equipment will bigger raising valuable mineral.
The purpose of this utility model is both to realize the high sharpness of separation of micro-size fraction mineral of laminar shear type shaking table, can improve the mineral disposal ability of shaking table again.
Mechanism of the present utility model is to adopt laminar shear technology sorting mined material from the gravity treatment principle, can realize the sorting of micro-size fraction mineral high accuracy.Because it has particular structure shape and working method, thereby has improved operating efficiency greatly.
Of the present utility model being characterised in that, adopt a kind of particular structure shape and working method, be that bed surface is an annular, with its center of circle serves as that axle is made differential torsional movement, the continuous bed surface that bed surface is made up of a plurality of minutes constituencies, both reach the high sharpness of separation of micro-size fraction mineral for this reason, improved the mineral disposal ability of single device again.
Task of the present utility model is achieved in that common shaking table bed surface all is a pane shape, and bed surface is done the straight line differential motion on its longitudinally, finish assorting room, and every shaking table bed surface only is a separation unit.And the bed surface of the utility model shaking table is the continuous bed surface of an annular, and serves as that axle is done differential torsional movement with the complete machine center, finishes assorting room, and bed surface is provided with several to dozens of separation unit (abbreviation constituency).The disposal ability of sorting mined material has obtained to increase substantially, and the multiple of its raising equals along the number in the constituency that the ring-type bed surface can be provided with.The number in constituency depends on the proterties of mineral itself and handles the grade requirement of mineral.Annular bed surface diameter is more than two meters the time, according to experiment showed, processing-100 purpose mineral, the minimum constituency that is provided with more than 15.
Sorting difficulty coefficient E is an index distinguishing the gravity treatment complexity, and E value computing formula is as follows:
E＝ (S
2-1)/(S
1-1)
Wherein, S
2--heavy mineral density, S
1--light mineral density;
It has been generally acknowledged that, be refractory minerals when the E value is lower than 1.25, is unsuitable for gravity treatment and adopts.And for laminar shear type gravitational separation equipment, it has not been refractory minerals that the E value is lower than 1.25.The utility model can make the E value be lower than 1.10, and the single device daily handling ability is about the 3-5 ton.
The shaking table bed surface gradient is preferred fixed value, and stroke, jig frequency and discharge all can be in operation and regulate continuously and reading.Because this shaking table has the uniformity of machine-building geometric parameter and the adjusting uniformity of mass motion parameter, discharge and the drift of exhibition angle thereof that mineral are selected band are synchronous variable condition; (change or the feed ore concentration variation as kinematic parameter) when the condition that sorts changes; band is selected in each constituency simultaneous bias will occur; the collection ore bucket that circularizes setting can be regulated in whole rotation, and is very accurate with comprehensive intercepting dressing product.Be equipped with servo control mechanism and photoelectricity with after combining device, can become current domestic and international state-of-the-art automatic industrial shaking table.This is an important feature of the present utility model.
The annular shaking table does not have the sort of horizontal plate washer that vertically shakes on the direction of common shaking table, and eliminated fully because plate washer returns and clapped the fish scale shape distribution disadvantage that resonance causes to the stream film, the laminar shear effect stability, sorting index greatly improves.
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the front view of the utility model annular shaking table;
Fig. 2 is the vertical view of the utility model annular shaking table;
The central dispense formula ore feeder 5 that ore pulp 4 is provided with from the shaking table top feeds.Ore feeder 5 is connecting the mineral-feeding pipe 6 that equates with annular bed surface constituency number, and ore pulp flows into each constituency of annular bed surface 2 through mineral-feeding pipe 6.Drive console 1 shaking table driving box (being commonly called as shaking table head) is housed, stir annular bed surface by moving arm 9 and do differential torsional movement, this torsional movement is equivalent to the straight line differential motion of common shaking table concerning each constituency of annular bed surface.Spray pipe 3 is provided with in the form of a ring along the bed surface inner edge, and the current that come out by spray pipe spray to the bed surface inwall, makes the full annular bed surface form uniform stream film.The annular shaking table is the cutting bed surface, and each constituency all is an independently cutting district.After ore pulp flows into each constituency, by the differential torsional movement of bed surface, loose, layering and centrifugation taking place in the bed groove, forms concentrate, chats, mine tailing various product and become the fan-shaped bed surface outer rim that flows to.Be provided with the annular collection ore bucket 7 of circumferential arrangement below annular bed surface outer rim, the collection ore bucket is divided into product tape that concentrate, chats mine tailing flow out facing to the bed surface outer rim respectively and carries out product intercepting (on the collection ore bucket of saying so exactly adjustable mine-separating board align product select band and intercept).Flow into the product gatherer 8 that is provided with around host center by collection ore bucket bend pipe 10 separately again, discharge by complete machine bottom 11 then.
