Abstract
The utility model relates to an airflow disintegrating machine of a multi-nozzle fluid bed, and a housing body is composed of a disintegrating chamber and a grading chamber. A grading wheel is arranged in the grading chamber, and both ends of the grading wheel are respectively connected with a grading shaft seat and a discharge port. The side wall of the middle portion of the disintegrating chamber of the housing body is provided with a feeding nozzle, and the lower portion of the disintegrating chamber is provided with a diagonal nozzle. The bottom of the disintegrating chamber is provided with a bottom nozzle, and the diagonal nozzle is connected with an air distributing ring. The airflow disintegrating machine of a multi-nozzle fluid bed has the advantages of small energy consumption, high efficiency, uniform processing fineness and convenient granularity adjustment.
Description
The utility model relates to a kind of high-effect air-flow ultramicro grinding equipment.
In the prior art, airslide disintegrating mill mostly is and catches up with the formula pulverizing or horizontalization is sprayed grinding mode, or the natural style air classification, and its pulverizing and classification efficiency and application adaptability all can not reach desirable effect, can not the adaptive technique requirement.
The purpose of this utility model provides a kind of multiinjector fluidized bed air flow crusher, present technique is to be working media with compressed air, by individual layer or double-deck opposite nozzles, spray high velocity air, material is quickened, make it produce collision tempestuously, shear, effects such as friction, the purpose of realization comminuting matter.By setting the rotating speed of turbine classifier, can adjust the granularity of pulverizing finished product easily.
The purpose of this utility model realizes by following measure:
The housing of multiinjector fluidized bed air flow crusher (5) is linked to each other with grading room by pulverizing chamber and constitutes, dress grading wheel (9) in its grading room, the barrel of grading wheel (9) is uniform flat blade, classification axle bed (7) and power wheel that grading wheel (9) one end coupling housings are outer, between classification axle bed (7) and the housing (5) cage (8) is arranged, the other end of grading wheel (9) is pegged graft and is drawn the outer discharging opening (10) of housing, the pulverizing chamber middle part sidewall of housing (5) has feed nozzle (6), the oblique nozzle that tilts to install is arranged on the lower sides of housing (5), quantity is 4-10, be angle [alpha]=60-90 ° with the axis, nozzle links to each other with dividing compression ring (3), and housing bottom has end nozzle (1).
Above-mentioned oblique nozzle is top nozzle (4) and the following nozzle (2) that relative tilt is installed, two rows and nozzle that divides compression ring to communicate and angle α=60-90 ° of axis, and quantity is 4-10.
Its operation principle is: material sprays by feed nozzle (6) and adds, compressed air ejects high velocity air by end nozzle (1), following nozzle (2) and top nozzle (4), material is quickened, make effects such as it collides tempestuously in intersection, shears, friction.The material that is crushed to certain fineness can pass through grading wheel (9) and discharging opening (10) discharge, and thicker material is blocked by grading wheel, returns again and pulverizes district's pulverizing once more.Form a logistics circulation, until being crushed to the setting fineness.
The utility model mainly contains following characteristics:
1, energy consumption is low, the efficient height.Owing to be oppositely arranged nozzle, impact energy far was better than and catches up with the formula pulverizing when it was pulverized, and crush efficiency can improve 30%-40%.
2, even particle size distribution is forced the turbine grading plant owing to be provided with, and can reduce excessive pulverizing or repeat and pulverize, and friendship mixing than corase particles capable of blocking goes out, and the finished product fineness is reached unanimity.
3, wearing and tearing are little, pollute few.Because pulverization mainly occurs in air-flow intersection, cavity is impacted very little, and material is by nozzle, avoids or reduced wearing and tearing, therefore pollutes thereupon and reduces.
4, granularity is easy to adjust.Owing to be provided with grading wheel and stepless speed-regulating device, can realize the granularity adjustment of finished product easily by changing the grading wheel rotating speed.
5, wide accommodation.This machine is applicable to material grinding such as high-purity, high rigidity, low melting point, thermal sensitivity, en plaque, fibrous, easy oxidation and high moisture contents.Structure adjusts the back slightly, can be used for that selectivity is pulverized or technological operations such as drying, classification, cladding.
The utility model is an example with the LQF-600 type, and when pulverizing 80% mancozeb wettable powder, its output is 500-600kg/ hour, and product fineness 90% is less than 6 microns, and 96% less than 10 microns, air consumption less than 40 standard cubic meters/minute.
Narrate below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
With reference to Fig. 1 is an embodiment of the present utility model, the housing of multiinjector fluidized bed air flow crusher (5) is linked to each other with grading room by pulverizing chamber and constitutes, dress grading wheel (9) in its grading room, the barrel of grading wheel (9) is uniform flat blade, classification axle bed (7) and power wheel that grading wheel (9) one end coupling housings are outer, between classification axle bed (7) and the housing (5) cage (8) is arranged, the other end of grading wheel (9) is pegged graft and is drawn the outer discharging opening (10) of housing, the pulverizing chamber middle part sidewall of housing (5) has feed nozzle (6), it is top nozzle (4) and the following nozzle (2) that relative tilt is installed that the oblique nozzle that tilts to install is arranged on the lower sides of housing (5), angle α=60 of two rows and the branch nozzle that communicates of compression ring and axis °, quantity is 6.Nozzle links to each other with dividing compression ring (3), and housing bottom has end nozzle (1).
