Description
Technical field
The present invention relates to a kind of experiment of powder metallurgy or production gradation tools, more particularly to a kind of annular iron powder
Grain sorting unit.
Background technique
China is industrial power, and the manufacturing industry in China flourishes with advances in technology, and economy is become stronger day by day, new technology
New material constantly emerges in large numbers, one of powdered metallurgical material.Powder metallurgy can manufacture porous, half fine and close or full compact part
Part, such as oiliness bearing, gear component, are widely used in various industrial trades, do not have to machining, have unique chemistry
Composition and mechanical, physical property, can not be obtained with traditional method for metal working, and wherein iron powder has at low cost practical
The strong feature of property and be widely used.Existing iron powder pulverulent product production technology typically first prepares the powder of appropriate particle size
Grain, is then pressed into type, re-sinters the component that can form fixed shape, sintered consistency and properties of product and powder
The size of grain has direct relation, and the requirement of different product is different, needs the powder particle of different-grain diameter equal according to different ratios
Even mixing can be only achieved desired effect, so being sieved to iron powder powder particle just seems that this pass is important, especially small quantities of
Even more important when amount production or experiment, existing screening is mainly sieved by sieve, due to requiring iron powder powder diameter obtained
Smaller, screen making is relatively difficult, at high cost, is easy to network blocking and is not easily cleaned, and adapts to the more practical tool of this needs at present
It is also weak, this is still solved up for technology.One is disclosed closest to prior art patent document (publication number CN104136127)
The equipment that kind is classified iron ore particle using magnetic force, drains into distribution chute for particle using distributor 103, in distribution chute
Magnetic force is applied to particle, then in classification chute part to gradation, the particle after classification is directed to conveyer belt (see the patent
Last 4th section of document specification), the particle for being classified out is only divided into two classes, higher than the iron ore of threshold concentration and it is obvious not by
Magnetic force attracts ore, is not suitable for multi-level hierarchical, while another patent document (publication number CN1056891123) discloses one kind
The equipment being classified using magnetic force to iron ore particle, magnetic fields make the raw transverse shifting of iron ore sofa carry out rough segmentation in iron ore sand,
The new ore in sand form stream of rough segmentation utilizes magnetic field to segment again, can accomplish multi-stage separation, and rough segmentation and subdivision need gradually laterally to open up to side
Space is opened up, occupied space is big, and the different grade particles that multi-stage separation comes out are offset vertically, and needs laterally to be arranged the separation of different height
And collecting mechanism, series is relatively more fixed, and the particle that the two comes out classification does not disclose how to avoid that transfer is isolated again,
It deals with improperly to be easy to cause and mix again.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of annular ferrous powder granules sorting units.
A kind of the technical solution adopted by the present invention are as follows: annular ferrous powder granules sorting unit, it is characterised in that including outer cylinder,
Outer cylinder upper inside is equipped with a guide cylinder coaxial with outer cylinder, and guide cylinder top is connected with coaxial funnel,
Coaxial inner cylinder is equipped in guide cylinder, inner cylinder top is equipped with the vertex of a cone, is equipped on the outside of outer cylinder lower half same with it
The magnet ring of axis, outer cylinder lower edge are equipped with circumferentially distributed gap；It is coaxial that at least two-stage and outer cylinder is equipped with below outer cylinder
Lower cylinder arranged up and down, lower cylinder lower edge is equipped with circumferentially distributed gap, along being connected with taper skirt, taper skirt on lower cylinder
On along outer diameter small square thereon outer cylinder or lower cylinder internal diameter, and along being higher than the gap height being in contact with it on taper skirt,
Taper skirt lower edge is connected with inclined delivery board, is equipped with coaming plate on the outside of delivery board, delivery board lower is connected with delivery outlet, each lower circle
Cylinder outside is equipped with coaxial magnet ring.
Further, the neighbouring delivery board is in 180 degree phase angle.
The present invention is classified for ferrous powder granules, and iron powder is packed into funnel when use, and iron powder falls into guide cylinder, in the vertex of a cone and interior
Under the action of cylinder, iron powder falls along annular runner, when flowing through magnet ring on the outside of outer cylinder, in the magnetic attraction of magnet ring
Under the action of move out, the particle motion amplitude of different quality is different, some lesser particles fall on taper skirt along with slit
Space at mouthful, and wandered by gap to delivery board classification and collected, it is then further classified through lower cylinder again, equipment is small and exquisite, nothing
Plug-hole problem.Cylinder coaxial arrangements at different levels, laterally occupy little space, lower cylinders at different levels are identical with taper skirt structure, only need cylinder
Stacking with taper skirt interval can be adjusted hierarchical level, and structure simple operations are more flexible, adjusts series and does not have to replacement complete equipment
At low cost, the Different Size Fractions separated are not easy to mix again.
Detailed description of the invention
Fig. 1 is overall schematic of the embodiment of the present invention.
Fig. 2 is schematic cross-sectional view of the embodiment of the present invention.
