Abstract

The utility model relates to a powder sieving device, in particular to sieving device for alumina abrasive. The sieving device comprises a sieve and is characterized in that the sieve is a tilted sieve, the sieve is arranged in a collecting tank and connected with a mixing tank, the collecting tank is connected with a filter, and the filter is connected with the mixing tank. The outer surface of micro-powder is coated with a high polymer material layer after that the micro-powder is soaked in high polymer washing liquor during sieving, and accordingly, particles of alumina micro-powder are smooth without edge corners.

Description

Alumina abrasive is crossed sieve apparatus
Technical field
The utility model relates to a kind of powder and crosses sieve apparatus, specifically is that a kind of alumina abrasive is crossed sieve apparatus.
Background technology
Grinding normally is primary raw material with aluminium hydroxide with alumina powder, adds additive, and aluminium hydroxide is calcined, and forms the tabular alumina powder, after carry out selectedly, pulverize and grind, carry out high accuracy classification, drying then, sieve, promptly get alumina powder.
The silicon chip of electron trade is in middle and later periods grinding and polishing process, and is very high to surperficial quality requirement, and a bit cut must not be arranged, and this just requires the alumina powder grain shape to want slick and sly, and the corner angle sharp shaped material must not be arranged, and it is very big that micro mist prepares difficulty.
The common technology of sieving of prior art can not satisfy the requirement that used in electronic industry grinds material.
Summary of the invention
The utility model provides a kind of alumina abrasive to cross sieve apparatus, applies layer protecting film when sieving on the alumina powder particle, has overcome the deficiencies in the prior art.
The following technical scheme of the concrete employing of the utility model:
A kind of alumina abrasive is crossed sieve apparatus, comprises screen cloth, it is characterized in that, screen cloth is the inclined screen cloth, and it is arranged in the feeder, and screen cloth is connected with blending tank, and feeder is connected with filter, and filter is connected with blending tank.
The utility model has the advantages that micro mist is by soaking in the macromolecule washing lotion when sieving, its outer surface has adhered to one deck polymer protection layer, makes alumina powder grain shape slyness, no corner angle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1-blending tank, 2-screen cloth, 3-feeder, 4-filter.
The specific embodiment
As shown in Figure 1, after alumina powder and macromolecule washing lotion mixed in blending tank 1, the macromolecule washing lotion after screen cloth 2 sieves, sieves was compiled at feeder 3, after washing lotion is filtered through filter 4 then, returned blending tank again and reused.
