Abstract
A powder concentrator material spreading disc comprises a round disc body provided with disc faces. Blades are arranged on the peripheric edge; an annular bevel is arranged on one disc face of the round disc body and is in a concentric circle structure with the disc faces of the round disc body; the annular bevel bevels towards the center of the disc faces. The annular bevel is arranged on one disc face of the round disc body, and material is spread in a delayed manner when reaching the material spreading disc accordingly; the material slides to the center of the disc body along the annular bevel before being spread outwardly and uniformly under the effect of centrifugal force.
Description
Technical field
The utility model relates to a kind of powder concentrator, particularly a kind of spreading disk of powder concentrator.
Background technology
The spreading disk of tradition O-Sepa powder concentrator rotating cage is an anchor ring, and particularly the semidiameter of the structure anchor ring of the upper air-out of employing is smaller, is difficult to powder is uniform along surrounding.This will make classification rotating cage surrounding occur thicker material curtain and the situation alternately occurring without material cavity, and this speed not only affecting in cylinder vortex field is even, also affects the follow-up dispersion of powder, thereby affects grading effect simultaneously.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the problem that the utility model solves is that material is at the circumferential skewness of spreading disk.
The technical solution of the utility model
A powder concentrator spreading disk, comprises circular disk body; Described circular disk body is established card; The edge of described circular disk body arranges blade; On one side panel face of described circular disk body, annular slope is set, the card of described annular slope and circular disk body is concentric structure; Described annular slope is centroclinal to card.
Further, in the middle of being provided with a side panel face of annular slope, circular depressed district is set, described circular depressed district and card are concentric structure.
The beneficial effects of the utility model
(1) on a side panel face of circular disk body, annular slope is set, while making material arrive spreading disk, postpones to be spread out, first along annular slope, slide into the middle part of disk body, then outwards spreading uniformly under the effect of centrifugal force.
(2) by the middle of card, circular depressed district being set, can be used as " temporary storage " of material, when material slides along annular slope, the storage that material can be of short duration, then spreading under the effect of centrifugal force, evenly better effects if.
(3) because material is fallen the circular card of rotation from charging aperture, to be shed immediately and disperse and meet with ascending air, fine grained, along with the air-flow rising moves upward, has reduced classification efficiency.Consider this problem, we arrange blade in circular disk body edge, during circular disk body rotation, form downward air-flow, just in time can offset the impact of ascending air.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of powder concentrator spreading disk, comprises circular disk body 1.Described circular disk body 1 is established card, and the edge of described circular disk body 1 arranges blade 11.On one side panel face of described circular disk body 1, annular slope 12 is set, the card of described annular slope 12 and circular disk body 1 is concentric structure.Described annular slope 12 is centroclinal to card.Further preferably, in the middle of being provided with a side panel face of annular slope 12, circular depressed district 13 is set, described circular depressed district 13 and card are concentric structure.On a side panel face of circular disk body 1, annular slope 12 is set, while making material arrive spreading disk, postpones to be spread out, first along annular slope 12, slide into the middle part of circular disk body 1, then outwards spreading uniformly under the effect of centrifugal force.By in the middle of card, circular depressed district 13 being set, can be used as " temporary storage " of material, when material slides along annular slope 12, the storage that material can be of short duration, then spreading under the effect of centrifugal force, evenly better effects if.Because material is fallen the card of rotation from charging aperture, to be shed immediately and disperse and meet with ascending air, fine grained, along with the air-flow rising moves upward, has reduced classification efficiency.Consider this problem, we arrange blade 11 in circular disk body 1 edge, during circular disk body 1 rotation, form downward air-flow, just in time can offset the impact of ascending air.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. a powder concentrator spreading disk, is characterized in that, comprises circular disk body; Described circular disk body is established card; The edge of described circular disk body arranges blade; On one side panel face of described circular disk body, annular slope is set, the card of described annular slope and circular disk body is concentric structure; Described annular slope is centroclinal to card.
2. powder concentrator spreading disk according to claim 1, is characterized in that, in the middle of being provided with a side panel face of annular slope, circular depressed district is set, and described circular depressed district and card are concentric structure.
