High-accuracy micro-powder graded machine
Technical field
The utility model relates to a kind of grader, particularly a kind of high-accuracy micro-powder graded machine.
Background technology
Pulverizing is the main means that obtain superfine powder, and the advantage of this method is that flow process is simple, can adapt to large-scale industrial production.Also there are many technology and problem economically yet only rely on single mechanical crushing equipment to produce superfine powder, as: the size distribution of milling product is difficult to control, pulverizes the energy consumption height, and production capacity is low etc.In addition, owing to exist extremely strong surface force between ultra-fine grain, strong mutual absorption and agglomeration can take place in particle in crushing process, and the thin more reunion of particle is just serious more.Because the inhomogeneity of material structure, promptly the otherness of structural strength makes that product granularity presents heterogencity in the crushing process, i.e. the broad spectrum activity of distribution of particles; Desire to make raw meal particle size all to reach granularity requirements, often need whole materials are continued long-time fine grinding, so not only expend a large amount of electric energy, and make the particle that reaches granularity requirements already produce pulverizing.Also do not have now the equipment that the particle that will reach granularity requirements at any time and coarse granule are separated on the market.
Summary of the invention
The purpose of this utility model just is to provide a kind of energy consumption low, production capacity height, and the high-accuracy micro-powder graded machine that can at any time the particle that reaches granularity requirements be separated with coarse granule.
To achieve these goals, the technical solution adopted in the utility model is such: high-accuracy micro-powder graded machine of the present utility model, comprise loading hopper, the 1# grader, the 2# grader, high-precision cyclone collector, pulse bag type dust collector, high-pressure suction fan and appliance controller, described loading hopper, the 1# grader, the 2# grader, high-precision cyclone collector, pulse bag type dust collector passed through the materials flow pipe successively with high-pressure suction fan and was connected, vertical machine all is set on described 1# grader and the 2# grader drives the internal vortex grading wheel, the 1# grader, the 2# grader, high-precision cyclone collector and pulse bag type dust collector are respectively equipped with the 1# material successively and collect mouth, the 2# material is collected mouth, the 3# material is collected mouth, the 4# material is collected mouth, described loading hopper, the 1# grader, 2# grader and high-precision cyclone collector are equipped with electronic unloader, described electronic unloader, vertical machine, high-precision cyclone collector, pulse bag type dust collector and high-pressure suction fan and appliance controller are electrically connected.
As preferably, also connect a silencer on the described high-pressure suction fan.
As preferably, described 1# grader, 2# grader all adopt vertical eddy current grading wheel.
As preferably, described vertical machine and 1# grader, 2# grader main shaft adopt direct-connected mode.
As preferably, described 1# grader, 2# grader drive motors are frequency control motor.
As preferably, described 1# grader, 2# grader, high-precision cyclone collector, pulse bag type dust collector, high-pressure suction fan, silencer are the mode of being connected in series.
As preferably, described 1# grader, 2# grader and high-precision cyclone collector four sides are fixed with railing.
Compared with prior art, advantage of the present utility model is: this grader technology and ultra-fine grinding equipment fit in closed circuit, and qualified products are in time separated, and coarse granule is regrinded after collecting mouthful collection by 1#, to improve classification efficiency and to cut down the consumption of energy.This grader can be isolated the product of different grain size scope, and narrow particle size distribution, and particle size range is adjustable, thereby product quality is improved, the disintegrating process consumption reduction that improves and economize on electricity.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, high-accuracy micro-powder graded machine of the present utility model, comprise loading hopper 9,1# grader 6,2# grader 5, high-precision cyclone collector 4, pulse bag type dust collector 3, high-pressure suction fan 2 and appliance controller, described loading hopper 9,1# grader 6,2# grader 5, high-precision cyclone collector 4, pulse bag type dust collector 3 passed through materials flow pipe 11 successively with high-pressure suction fan 2 and was connected, vertical machine 7 all is set on described 1# grader 6 and the 2# grader 5 drives the internal vortex grading wheel, 1# grader 6,2# grader 5, high-precision cyclone collector 4 and pulse bag type dust collector 3 are respectively equipped with the 1# material successively and collect mouth 13, the 2# material is collected mouth 14, the 3# material is collected mouth 15, the 4# material is collected mouth 16, described loading hopper 9,1# grader 6,2# grader 5 and high-precision cyclone collector 4 are equipped with electronic unloader 12, described electronic unloader 12, vertical machine 7, high-precision cyclone collector 4, pulse bag type dust collector 3 and high-pressure suction fan 2 are electrically connected with appliance controller, also connect a silencer 1 on the described high-pressure suction fan 2, described 1# grader 6,2# grader 5 and high-precision cyclone collector 4 four sides are fixed with railing 8, described 1# grader 6,2# grader 5 all adopts vertical eddy current grading wheel, described vertical machine 7 and 1# grader 6,2# grader 5 main shafts adopt direct-connected mode, described 1# grader 6,2# grader 5 drive motors are frequency control motor, described 1# grader 6,2# grader 5, high-precision cyclone collector 4, pulse bag type dust collector 3, high-pressure suction fan 2, silencer 1 is the mode of being connected in series.
