Abstract
The utility model provides a high-precision grader which comprises an eddy flow grading unit and a forcing grading body arranged above the eddy flow grading unit. A feeding port is arranged above the eddy flow grading unit, the upper end of the forcing grading body is fixed with a top cap, and a gravity grading unit is arranged below the eddy flow grading unit. A coarse powder discharge port is arranged below the gravity grading unit, and the coarse powers graded by the eddy flow grading unit are further graded by the gravity grading unit. The coarse powders graded by the gravity grading unit are discharged from the discharge port and fines overflowing from the gravity grading unit are absorbed into the eddy flow grading unit to be graded again. The high-precision grader has the advantages of being capable of effectively improving grading precision and grading efficiency, providing more bearing capacity for a spindle, enabling the spindle to bear a larger-sized grading wheel, and helping improve the grading efficiency and grading precision due to the fact that a fine discharge port is arranged on the side wall of a discharge device, the end of the discharge device is sealed and connected with the spindle.
Description
Technical field
The utility model relates to a kind of industrial attritive powder grader, is specifically related to a kind of high accuracy grader that can improve effectiveness of classification and classification efficiency.
Background technology
In the prior art, powder particle that industrial attritive powder grader all is based on different quality has these characteristics of different centrifugal force and is isolated and comes in centrifugal field force, the vertical grader of the forced vortex of prior art for example, raw material disperses rapidly under powerful vortex power effect after entering grader immediately, the thickness powder separates, enter follow-up fines collection system after classified wheel of fine powder of the satisfied granularity requirements of setting, remaining meal and reunion shape fine powder drop to the eddy current stage unit, the spiral centrifugal ascending air that is produced by cyclone disperses strongly to material, make thickness powder Re-isolation, fine powder after the dispersion enters graded region with ascending air and carries out again classification, meal continues to drop to wind-supplying mouth, again accept the dispersion treatment of air blast, make the thickness powder separately, fine powder continues to the classification of getting on, and meal is discharged outside the grader downwards.But the fine powder that this grader classification goes out is thin not, and classification efficiency is also not high enough.
The utility model content
In order to overcome defects, the utility model provides a kind of high accuracy grader, and this high accuracy grader can improve effectiveness of classification and classification efficiency, and simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of high accuracy grader, the enforced classification body that comprises the eddy current stage unit and be positioned at eddy current stage unit top, charging aperture is positioned at eddy current stage unit top, described enforced classification body upper end is fixed with top cover, described eddy current stage unit below is connected with the gravity classification unit, and lower end, described gravity classification unit is the meal discharging opening.
The utility model for the further technical scheme that solves its technical problem and adopt is:
Described enforced classification body comprises grading wheel and rotating shaft, described grading wheel is fixed in rotating shaft, be provided with discharger, described discharger one end is connected with described enforced classification body sidewall, described discharger other end sealing, the sidewall of described discharger is provided with the fine powder discharging opening, and described rotating shaft one end connects driving arrangement, and the described rotating shaft other end is connected with the other end of described discharger sealing.
Be provided with intermediate, be communicated with by described intermediate between described eddy current stage unit and the described enforced classification body.
The eddy current stage unit comprises cyclone.
The beneficial effects of the utility model: the utility model is set up the gravity classification unit one below the eddy current stage unit, the meal that the classification of eddy current stage unit is gone out further passes through the classification of gravity classification unit, the fine powder that the meal that the gravity classification unit is told is overflowed by meal discharge hole for discharge gravity classification unit then is sucked into the eddy current stage unit and carries out again classification, can Effective Raise effectiveness of classification and classification efficiency; And the fine powder discharging opening is arranged at the sidewall of discharger, and is connected with the endcapped of discharger and with rotating shaft, can provide rotating shaft larger bearing capacity, make rotating shaft can carry larger sized grading wheel, be conducive to the raising of classification efficiency and effectiveness of classification.

Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment: a kind of high accuracy grader, the enforced classification body 2 that comprises eddy current stage unit 1 and be positioned at eddy current stage unit top, charging aperture 3 is positioned at eddy current stage unit top, described enforced classification body upper end is fixed with top cover 4, described eddy current stage unit 1 below is connected with gravity classification unit 5, and lower end, described gravity classification unit is meal discharging opening 6.
Described enforced classification body 2 comprises grading wheel 21 and rotating shaft 22, described grading wheel is fixed in rotating shaft, be provided with discharger 7, described discharger one end is connected with described enforced classification body sidewall, described discharger other end sealing, the sidewall of described discharger is provided with fine powder discharging opening 71, and described rotating shaft one end connects driving arrangement 8, and the described rotating shaft other end is connected with the other end of described discharger sealing.
Be provided with intermediate 9, be communicated with by described intermediate 9 between described eddy current stage unit 1 and the described enforced classification body 2.
The eddy current stage unit comprises cyclone 11.
Operating process of the present utility model and principle are as follows:
After raw material enters grader of the present utility model, under the powerful vortex power effect of eddy current stage unit, disperse rapidly immediately, the thickness powder separates, meal enters the gravity classification unit downwards and further carries out the separation of thickness powder, and fine powder then enters under the ascending air effect and further carries out the separation of thickness powder in the enforced classification body; In the enforced classification body, enter discharger after classified wheel of fine powder of the granularity requirements of satisfy setting and from the fine powder discharge hole for discharge, remaining meal and reunion shape fine powder drop to the eddy current stage unit, the spiral centrifugal ascending air that is produced by cyclone disperses strongly to material, makes thickness powder Re-isolation; At place, gravity classification unit, meal then is sucked into the eddy current stage unit by meal discharge hole for discharge fine powder and carries out again classification.
