Fig. 1 is a kind of structural representation of preferred embodiment of the invention.
Fig. 2 is Fig. 1 overlooking the structure diagram.
Fig. 3 is a kind of cross section structure diagram of preferred embodiment of the invention.
Embodiment
The present invention is discussed in detail with reference to Fig. 1, Fig. 2 and Fig. 3：
Hollow crushing is provided with the grinding system of innovation type fluidized bed airflow grinding machine, including frame 80, the frame
Cylinder 801, pulverization cylinder lower end closed, upper end are that discharging opening 802, middle part are provided with charging aperture 803, in pulverization cylinder bottom along its perisporium
Multiple valves 804 are evenly equipped with, the gas collection that multiple valves are ejected is in the home position where the plurality of valve so as to be formed
Clashed gas, such as sets 2 valves, and 2 valves are arranged in opposite directions, and its gas sprayed collides；Such as set 3 or more
Individual valve, then these valves be circumferentially uniformly distributed, its gas ejected converges at the center of circle and collided；From the charging
Mouth enters powder thicker in the powder in pulverization cylinder and the head-on collision that multiple valves are ejected is moved downwardly under its Action of Gravity Field
Gas, that is, move to the center of collecting of valve, and the powder of head-on collision air impingement center crushes it, then in suction function
Under, the powder after being crushed through the gas that clashes overcomes gravity to flow upwardly toward the thinner powder in the discharging opening, powder and overcomes weight
Power flows to discharging opening directly up, so as to realize classification, crushing.
It is provided with to be provided with the cover 805 for covering the discharging opening, cover in implementation process, on discharging opening and can stretches into powder
Grading plant 806 in broken cylinder, under suction function, flows to powder relatively thin in the powder of discharging opening out of grading plant
Chamber flows out, and relatively thick powder is back to head-on collision gas and crushed again, so circulation, until the powder in pulverization cylinder is all logical
Untill crossing grading plant.It can be seen that, pulverizer of the invention can not only be crushed to powder, and using negative pressure and gravity to powder
Body carries out secondary grading, so that ensureing the diameter of particle of output has the higher uniformity.
The grading plant 806 of the present invention includes driving the hollow grading wheel 808 that rotation is stretched into pulverization cylinder by rotating shaft 807,
The grading wheel is connected with the hollow material discharging wheel 809 being arranged on axis of rotation on cover, and material discharging wheel inner chamber connects with grading wheel inner chamber
Logical, relatively thin powder enters grading wheel inner chamber under suction function on the outside of the grading wheel of rotation, then out of grading wheel
Chamber flows into material discharging wheel inner chamber, then from the outflow of material discharging wheel inner chamber, so as to collect powder；The grading wheel includes the upper lower rotary table of annular
810th, 811 and the idle wheels 812 that are arranged between lower rotary table, the rotating shaft sequentially passes through top rotary table 810, the and of runner 812
Lower rotary table 811, rotating shaft bottom is fixedly connected with lower rotary table, and the runner connects upper lower rotary table by the two ends being circumferentially spaced apart
Several columns composition, the relatively thin powder enters runner cavities from the gap between two adjacent upright, then from turning
Take turns inner chamber and flow into material discharging wheel inner chamber.Because the column of circle distribution is rotated with rotating shaft, the gap between two adjacent upright with
The increase of rotating speed is in the shorter residence time of same position, and thinner powder self gravitation is smaller, shorter by off time,
Therefore the gap that powder only thinner in the presence of negative pressure can just enter between two adjacent upright, and then enter in runner
Chamber.In implementation process, the fineness of particle classifying can be by adjusting the velocity interpolation of rotating shaft.Preferably, the material discharging wheel and
The guide cup 813 that top rotary table inner ring is provided through between runner and is connected with runner cavities, the similar funnel of guide cup can be improved
Discharge efficiency.
In implementation process, air seal set 814 is installed between the material discharging wheel and cover, can prevent powder from entering discharging
Take turns the gap between cover and influence grading plant to rotate；Manually or automatically device 815 is opened or closed the cover,
