Description
Technical field
The invention belongs to powder concentrator fields, and in particular to a kind of powder concentrator spreading disk.
Background technique
Currently, being used for the powder concentrator of powder body material classification and sorting, mainly pass through high-speed rotating spreading disk for powder
It sheds to powder-separating area, under the action of high speed rotor and air-flow, fine powder is expelled in subsequent dust-precipitator from air outlet and is collected,
And coarse powder is then fallen into the ash bucket of lower section.Since existing spreading disk is usually single layer disk body, thus the material cake thickness spread out
It is thicker, bad dispersibility, and be unevenly distributed on spreading disk, it is easy to produce the phenomenon that coarse powder mixing fine powders are fallen, influences to select powder
Effect.Spreading disk runs at high speed down and is easily damaged in uneven stress for a long time.
Summary of the invention
For above-mentioned deficiency present in the prior art, the technical problem to be solved by the present invention is to existing powder concentrator spreading disks
It is difficult to disperse the material cake of agglomeration, and uneven accumulation, influences to select powder effect；Spreading disk structural strength is inadequate.
In order to solve the above technical problem, the present invention provides a kind of powder concentrator spreading disks, including upper receiver, lower spreading
Disk, material casting plate, transmission shaft,
The upper receiver and lower spreading disk are coaxially disposed up and down, the circle that the upper receiver and lower spreading disk pass through center
Cylindrical transmission shaft is fixed together, and the center transmission shaft is provided with mounting hole and connect with driving motor,
The upper receiver is plate-like, and the upper receiver includes the hole that gathers materials in central platform and outside, the hole that gathers materials
Section be two sections of camber lines, and close to outer rim arc curvature of a curve it is smaller；
The lower spreading disk is cylinder, and the material casting of the plate of multiple standings is provided on the outside of the lower spreading disk upper surface
Plate, the adjacent material casting plate interval angles are 8 to 12 degree,
The lower spreading disk lower surface is provided with multiple reinforcing ribs.
Further, in order to smash the material cake of agglomeration, the upper receiver upper surface is provided with multiple particles protrusions, described
Particle protrusion is uniformly circumferentially disposed in multi-turn, altitude range 10-35mm.
Further, Embedded particle protrusion falls damage powder concentrator in order to prevent, the particle protrusion be it is hemispherical,
And with upper receiver integrally casting shaping.
Further, in order to save material and mitigate load, multiple lightening holes are provided on the lower spreading disk, it is described to subtract
Repeated hole be sector, positioned at the upper receiver the lower spreading disk view field.
Further, the material casting plate and reinforcing rib are one block of plate, are welded on the outside indentation, there of the lower spreading disk.
The working principle of the invention:
It is provided with the hole that gathers materials on the outside of upper receiver, powder can be gathered in the hole that gathers materials of trench, under the action of the centrifugal force
It concentrates and spreads the lower spreading disk to lower layer；Upper receiver upper surface setting particle protrusion, stress are concentrated, can break the material cake of agglomeration
It is broken, cooperate centrifugal force, impact force can further break up powder when dispersing feed powder, while falling on lower spreading disk.Lower spreading disk by
Big in area, intensity requirement is high, welds reinforcing rib in bottom, can increase the intensity of faying face.
The beneficial effects of the present invention are:
The present invention uses double-layer structure, and the material cake that receiver is spread out in impact is allowed to be easier to disperse.It is provided with and gathers materials simultaneously
Hole, delays spreading, keeps feed powder uniformity more preferable；Using reinforcing rib, enhance spreading disk structural strength.

Specific embodiment
Particular content of the invention is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, 2, a kind of powder concentrator spreading disk, including upper receiver 1, lower spreading disk 4, material casting plate 5, transmission shaft 7,
The upper receiver 1 and about 4 lower spreading disk are coaxially disposed, the cylinder that the upper receiver 1 and lower spreading disk 4 pass through center
Transmission shaft 7 be fixed together, the transmission shaft 7 is provided centrally with mounting hole and connect with driving motor,
As shown in Figure 4,5, the upper receiver 1 is plate-like, and the upper receiver 1 includes gathering materials for central platform and outside
The section in hole 3, the hole 3 that gathers materials is two sections of camber lines, and smaller close to the arc curvature of a curve of outer rim；
The lower spreading disk 4 is cylinder, and the throwing of the plate of multiple standings is provided on the outside of lower 4 upper surface of spreading disk
Flitch 5, adjacent 5 interval angles of material casting plate are 8 to 12 degree,
