Abstract
The utility model discloses a super-fine powder grader, which is characterized in that the internal part of the casing is provided with a circular fixing bracket; the internal part of the fixing bracket is provided with more than two curved rotary plates which have elasticity and can be spliced into cylindrical; the size of the gap of the engaged edges of the adjacent curved rotary plates can be regulated through a regulating rod, and accordingly, the grading fineness can be controlled. The utility model has wide grading ranges, and according to the size of the particle diameter, the super-fine powder materials can be divided into a plurality of levels. The 3-31 um particles in the powder materials are individually separated as a particle diameter stage of 0 to 3 um/0 to 5 um/0 to 10 um; the handling capacity is 1 to 1.5t/h, and the yield is 50 to 300 kg/h.
Description
The utility model belongs to the powder grading plant, is specifically related to a kind of superfine powder clasfficiator.
Existing powder grading plant comprises screen drum and the spreading disk be made up of grating, and powder enters the charging tray of removing of rotation at a high speed by charging aperture, and centrifugal force is broken to grating powder, and fines is flowed out by the fines outlet through grating, and coarse fodder flows out from the coarse fodder outlet.This separator, grading range is single, and actual separating effect inaccuracy works hardly to superfine powder.
The purpose of this utility model aims to provide a kind of superfine powder clasfficiator that can tell a plurality of rank powders according to particle size.
For reaching above-mentioned purpose, the utility model adopts following solution: comprise housing, its top is the Cylinder of band top cover, the bottom is the cone table of falling the garden that welds together with top, be provided with the fines outlet in the middle of the top, side is provided with charging aperture, the lower end is provided with the coarse fodder outlet, it is characterized in that: the top in the housing is provided with garden annular fixed support, fixed support is welded on the housing top cover, support bracket fastened inside is provided with the hook plate of being with elasticity and being combined into garden shape more than two, the size in gap can be adjusted by the adjusting lever on the fixed support between adjacent two blocks of hook plates, one side of hook plate is welded on the fixed support, hinge on another side and the adjusting lever is articulated and connected, and adjusting lever is that two is fixed and rotatable vertical shaft, and one is fixed on the fixed support, the other end is stretched out the housing top cover and is fixed on the top cover, and adjusting lever is arranged on the place, identical limit of two blocks of hook plates; Charging aperture directly feeds in the hook plate in the garden by bend pipe; The fines outlet is provided with stretches to the middle garden pipe of hook plate.
Operation principle of the present utility model: this clasfficiator adopts negative-pressure air fan air inducing, and wind-force connects material from the milling apparatus discharging opening by pipeline, and the wind-force band powder and entered clasfficiator by conveying pipeline, does the rotating centrifugal motion.The coarse granule powder is thrown on the hook wooden partition under action of centrifugal force, but also has quite a few fine powder also can't classification with the meal movement of particles.At this moment, adjust the size in the identical gap, limit of two blocks of hook plates by adjusting lever, the increase in gap, limit owing to coincide, form the wave state in the garden bucket that the hook plate is combined into, the powder rotation changes angle in rotary course when throwing to the hook wooden partition, entad be used to power thereby produce, make powder throw to remove and be dispersed to secondary separation in the whirlwind.Because wind speed is exceedingly fast,, improve classification efficiency through repeatedly shedding dispersion.The size in the identical gap, limit of hook plate, the fineness of control classification mainly is the parallel point of control centrifugal force and centripetal force.Centrifugal force is changeless, the size of the size decision graded particie of centripetal force.Coarse granule collects by the coarse fodder outlet after the classification, and fine grained enters separator by the fines outlet and separates, and finishes classification procedure.
Compared with prior art, the utlity model has following advantage:
1, because the utility model is provided with the size that adjusting lever is adjusted gap between the identical limit of hook plate, thereby the fineness of control classification so the utility model grading range is wide, can be told a plurality of other superfine powders of level according to particle size.
2, the actual separating effect of the utility model is accurate, can separate separately the particulate of 3-31 μ m in the powder with 0-3 μ m/0-5 μ m/0-10 particle diameter stage of μ m, treating capacity 1-1.5t/h, the time produce 50-300kg.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1, cutaway view of the present utility model.
The A-A view of Fig. 2, Fig. 1.
Fig. 3, outside drawing of the present utility model (the fines exit is cut open).
As Fig. 1,2, shown in 3, the utility model comprises housing 1, its top is the Cylinder of band top cover, the bottom is the cone table of falling the garden that welds together with top, be provided with fines outlet 2 in the middle of the top, side is provided with charging aperture 3, the lower end is provided with coarse fodder outlet 4, top in its housing 1 is provided with garden annular fixed support 5, fixed support 5 is welded on housing 1 top cover, the hook plate 6 that the inside of fixed support 5 is provided with three band elasticity and can be combined into garden shape, the size in the gap between adjacent two blocks of hook plates 6 can be adjusted by the adjusting lever on the fixed support 57, one side of hook plate 6 is welded on the fixed support 5, hinge 8 on another side and the adjusting lever 7 is articulated and connected, and adjusting lever 7 is that two is fixed and rotatable vertical shaft, and one is fixed on the fixed support 5, the other end is stretched out housing 1 top cover and is fixed on the top cover, and adjusting lever 7 is arranged on the place, identical limit of two blocks of hook plates 6; Charging aperture 3 directly feeds in the hook plate 6 interior gardens by bend pipe 9; Fines outlet 2 is provided with stretches to the middle garden pipe 10 of hook plate.
