Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

As shown in Figures 1 to 3, powder recovering device includes suction ventilator 1, suction nozzle 2, separating barrel 3, collecting vessel 4, discharge pipe 5；

Separating barrel 3 is the pipe of upper and lower end face closing；The inner wall of separating barrel 3 is equipped with from one end of separating barrel 3 to the other end Spiral groove 31；The cross section of spiral groove 31 is arch；The interior of spiral groove 31 passes through hole 32 equipped with powder；Powder End is reduced with the distance of the bottom away from spiral groove 31 and increase by the density in hole 32；Suction nozzle 2 is mounted on separating barrel 3 A blind end on, another closed end of the separating barrel 3 opposite with suction nozzle 2 is equipped with discharge pipe 5, and suction nozzle 2 is in With the spiral shape of the form fit of spiral groove 31, the gas outlet face spiral groove 31 of suction nozzle 2；Suction nozzle 2 into Gas port is connected with the gas outlet of suction ventilator 1；

4 outer wrapping of collecting vessel is in the outside of separating barrel 3, and two end faces are equipped with annular slab 6；The inner end of each annular slab 6 The outer surface in face and two end faces of separating barrel 3 is seamless affixed；

Separating barrel 3 is followed successively by metal layer 8, plastic layer 7 from outside to inside；Powder in plastic layer 7 by the height in hole 32 not More than 0.5 millimeter；Collecting vessel 4 is made of metal material；The metal layer 8 of separating barrel 3 is electrically connected with a pole of low-voltage；Collecting vessel 4 ground connection.

Pass through and spiral groove 31 is set in the separating barrel 3 so that particles of powdered ingredient in air is in the work of centrifugal force With lower absorption on the inside circumference face of separating barrel 3；Again by the powder on spiral groove 31 by hole 32 by powder raw material Particle is collected；And by the way that separating barrel 3 is arranged to plastic layer 7 and metal layer 8, and one end of metal layer 8 and electrode is electric Connection can prevent powder coating particles to be adhered to powder by hole 32, so as to influence the collection of particles of powdered ingredient, and After particles of powdered ingredient is contacted with metal layer 8, it can be promoted with charge and pass through the particles of powdered ingredient in hole 32 positioned at powder Into in collecting vessel 4.

In the present embodiment, the spacing of each circle of spiral groove 31 is equal to 1/3rd of 31 width of spiral groove； The interior walls be smooth transition of spiral groove 31 and separating barrel 3.

Air formation in spiral groove 31 can be reduced by that will be arranged to seamlessly transit between spiral groove 31 Turbulent flow.

In the present embodiment, several bar-shaped troughs 33 along 31 hand of spiral of spiral groove are equipped in spiral groove 31；Powder End is arranged in by hole 32 in bar-shaped trough 33；The width of bar-shaped trough 33 is not less than diameter of the powder by hole 32；Bar-shaped trough 33 It is interior to be equipped with the guide groove 34 for being directed toward circular hole obliquely；The oblique direction of guide groove 34 is the air flow side in spiral groove 31 To.

By setting bar-shaped trough 33, it is ensured that adsorbed the powder in spiral groove 31 under the influence of centrifugal force Powder stock particle is not in be again introduced into the hollow space of separating barrel 3.Set guide groove 34 that can guide powder raw material Grain passes through hole 32 into powder.

In the present embodiment, the metal mesh 9 being enclosed on the outside of 3 outer surface of separating barrel worked out by flat-shaped metal strip is further included； The surface that two pieces of annular slabs 6 of collecting vessel 4 are opposite is equipped with annular groove 61；The both ends of metal mesh 9 are located at two annular grooves In 61, other two end face of metal mesh 9 is fixedly connected with each other.

By setting metal mesh 9 and being grounded, it is possible to reduce particles of powdered ingredient does not exist since band same sex charge repels Deposition in collecting vessel 4.

In the present embodiment, powder is become larger by the diameter in hole 32 by inside to the outside of separating barrel 3.Powder can be reduced Powder stock particle is blocked in powder and passes through hole 32.

In the present embodiment, 4 outer wall of collecting vessel is equipped with closed opening-door plate 10.Facilitating will be deposited in collecting vessel 4 Particles of powdered ingredient taking-up reuse.

The utility model so works, and the suction nozzle of the present apparatus is aligned agitator, starts suction ventilator 1, in suction ventilator 1 Under the action of, the floating above agitator has the gas of dust particles by entering back into suction nozzle 2 after suction ventilator 1, in suction nozzle 2 Guiding role under, gas is in being discharged into separating barrel 3 obliquely of rotation, and under the rotation of gas, particles of powdered ingredient exists The inner wall in separating barrel 3 is adsorbed under the action of centrifugal force, and with the effect of air-flow, moves in bar-shaped trough 33, finally moves To guiding groove, finally under the influence of centrifugal force into powder by hole 32, into powder by hole 32 after, connect with metal layer 8 It touches, Partial charge thereon is transferred on particles of powdered ingredient by metal layer 8, so as to which particles of powdered ingredient will not be mutually by stifled Plug powder passes through hole 32.

Particles of powdered ingredient passes through powder by being contacted behind hole 32 with the metal mesh 9 in collecting vessel 4, its is subsidiary Charge transfer is finally fallen on metal mesh 9 in collecting vessel 4.After completion of stirring, suction ventilator 1 is closed, is opened on collecting vessel 4 Opening-door plate 10, by collecting vessel 4 particles of powdered ingredient take out.

Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this The technical solution of utility model is modified or replaced equivalently, should all without departing from the objective and scope of the technical program Cover among the right of the utility model.
