Description
Technical field
The present invention relates to the method and devices that impurity in material sorting field more particularly to a kind of granule materials sorts.
Background technology
Wood-based plate is to be separated into various unit materials through being centainly machined using timber or other non-wood plants as raw material
Afterwards, apply or do not apply plank or pressing made of adhesive and other additive gluings.
Certain form of wood-based plate in process, needs the material particles that will be crushed to sort, and chooses volume
With all suitable material particles of density, they are excessive with volume, the feed separation that density is excessive or bulk density is all excessive
It comes.
Current sorting unit is mostly linear vibrating screen, spin vibration sieve etc., and basic principle is the vibration by sieve, will be small
The material of particle sorts out, but such sorting unit can not be close by volume, but the material particles that density difference is bigger
It separates, needs further to detach material particles using centrifugal separator etc., further sub-elect volume and density all
Suitable material particles, not only sorting step is more, and the structure of sorting unit is more complicated, and maintenance is cumbersome, is unfavorable for
The continuity of coarse fodder, high efficient sorting.
Invention content
Technical problem to be solved by the present invention lies in the method for separating of impurity in a kind of granule materials of offer and application should
The sorting unit of method, this method and device can be acted by disposably sorting, by volume and all suitable material of density
Particle is separated from mixtures of materials, and apparatus structure is simple, good reliability, is conducive to continuity, the height of coarse fodder
Efficiency sorts.
The present invention is achieved by the following technical solutions：
The method for separating of impurity in a kind of granule materials, it is characterised in that：
By mixtures of materials to be sorted with an initial velocity downwards, boundling is continued towards at column the vertex of a cone position of cone and inclines
It unloads,
Wait for that sorting material mixture slides along the conical surface of cone, during landing, the thickness of mixtures of materials by diameter by
Gradually the increased conical surface is made thinner, and in membranaceous dynamic coverage on the conical surface, bottom outer rim is bored up to mixtures of materials slides to cone bottom, edge
Curtain waterfall shape continues to fall in a ring,
Sorting area of the curtain waterfall shape mixtures of materials in dropping process Jing Guo a negative pressure, by negative-pressure ward, volume and density
All suitable material particles are detached from mixtures of materials curtain waterfall and by negative-pressure ward towards the underlying space movement on the inside of cone bottom outer rim
Export the space, volume and/or the excessive material of density continue to fall and be collected in curtain waterfall shape.
Mixtures of materials is made thinner into curtain waterfall shape by this method first with the conical surface discharging structure of cone, and curtain waterfall is being dropped through
During the sorting area of one section of negative pressure, volume and all suitable material particles of density can be influenced by negative-pressure ward, direction
The movement of negative pressure higher region, volume and/or the excessive material of density will not be influenced by negative pressure, or by influenced compared with
It is small, it is whole still to keep continuing the trend to fall in curtain waterfall shape, to which volume and all suitable material particles of density are detached sorting
Out.
Mixtures of materials make thinner be in order to ensure particle in mixtures of materials can abundant stress, mixtures of materials exists
It is too small by blocked up or stress outer surface when the sorting area of negative pressure, the sorting of material particles can be all influenced, the efficiency of separation is caused
It is low, it may be necessary to repeatedly repeatedly sorting can be only achieved make thinner after the effect that sorts again.
It is made thinner using the conical surface of cone, not only thinning effect is good, is conducive to continuity sorting, and structure of making thinner is non-
It is often simple, compared with the existing transfer roller using more height configurations makes thinner structure, in device manufacturing cost and maintenance cost
Advantage clearly.
Further, the height in the sorting area, negative pressure value and wind speed can adjust separately, by adjusting the height in sorting area
Degree, can control the particle volume sub-elected and/or density；By adjusting the negative pressure value in sorting area, it can also control and sub-elect
Particle volume and/or density；By adjusting the wind speed in sorting area, it is adapted to the variation of mass flow.
