Abstract
The invention relates to a gravity and air grader of fine powder which comprises a charging machine, a material inlet, an adjustment block A, an adjustment block B, an adjustment valve A, an adjustment valve B, an adjustment valve C, an adjustment block D, an adjustment valve D, an adjustment valve E and a grading chamber. The material inlet is located at the top of the grading chamber. The gravity and air grader of fine powder achieves the technical effect of high-accuracy graded products.
Description
Technical field
The present invention relates to a kind of fine powder grader, particularly a kind of fine powder gravity adds air classifier.
Background technology
Classification to be carried out to Crushing of Ultrafine product in ink powder production process, bulky grain should be removed and remove granule again, obtain the classification product that epigranular is consistent, at present, the fine powder grader used adopts straight feeding, horizontal blast only utilizes wind-force to be blown into by material, under the effect of air-introduced machine, in grading room, produce negative pressure carry out fine powder, middle powder, meal classification, this stage division very inaccuracy, be difficult to obtain high-precision classification product.
Summary of the invention
In view of prior art Problems existing, the invention provides a kind of gravity and add air classifier, concrete technical scheme is, a kind of fine powder gravity adds air classifier, comprise charger, charging aperture, adjustment block A, adjustment block B, regulating valve A, regulating valve B, regulating valve C, adjustment block C, regulating valve D regulating valve E, grading room, blowing mouth, it is characterized in that: described charging aperture is positioned at grading room top, make the blowing mouth of former side become vertical configuration with charging aperture.
Technique effect of the present invention to obtain high-precision classification product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a charging aperture 2 is opened at grading room 11 top, make the blowing mouth 12 of former side and charging aperture 2 one-tenth vertical configuration, the material of classification is needed to send into charging aperture 2 by oscillating batch charger 1, material enters grading room 11 straight down at a high speed under the effect of wind-force and gravity, and generation negative pressure grading room 11 under the effect of air-introduced machine, according to gravity and principle of inertia, bulky grain is the malleable direction of motion not, and granule easily changes direction.So bulky grain enters meal collecting pipe downwards at a high speed, air quantity regulating valve C7 can control coarse grained inlet.Granule enters fines collection pipe under the effect of horizontal wind-force, air quantity regulating valve A5 can control the inlet of fine powder, certified products enter middle powder collecting pipe, the inlet of powder during air quantity regulating valve B6 controls, adjustment block A3. controls the classification point of fine powder and middle powder, the classification point of powder and meal during adjustment block B4 controls, air quantity regulating valve E9, F10 controls the negative pressure about-10 kPas of intake and grading room, and adjustment block D8 controls air intake direction, can obtain high-precision classification product by many ways adjusting.
