At present, in the prior art, dry method material pneumatic disintegrating apparatus has two kinds of fluidized bed air flow crusher and horizontal circle disc type airslide disintegrating mills.The principle of fluidized bed air flow crusher is that the bottom is that the pulverizing nozzle that is oppositely arranged is used for discharging supersonic airstream material is collided relatively, material is the fluid bed attitude in cavity, the grader parts on top make the particle that reaches fineness in time isolate main frame, be gathered into the finished product material outside, its effectiveness of classification is higher, the particle that reaches fineness can in time be isolated the High-efficient Production characteristics of main frame, but the air-flow that its nozzle discharges hits by comminuting matter probability height; The principle of disc type airslide disintegrating mill is to pulverize the tangential direction of circle along imagination at horizontal circumferencial direction, some pulverizing nozzles that distributing are relatively all arranged, when nozzle discharges supersonic airstream, make material in narrow crushing chamber, do rotation at a high speed, utilize the centrifugal force of granule materials to produce grading, pulverized fine granular materials is fled from main frame with air-flow, produces product.Its structure is comparatively simple, is convenient to clean, and gas shock is by comminuting matter probability height, but its effectiveness of classification is poor, has bulky grain to exist in the product.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of effectiveness of classification that had both had a fluidized bed air flow crusher higher, the particle that reaches fineness can in time be isolated the High-efficient Production characteristics of main frame, and the air-flow that has the nozzle release of disc type airslide disintegrating mill again hits by the dry method material pneumatic disintegrating apparatus of the high characteristics of comminuting matter probability.
The purpose of this utility model can reach by following measure:
A kind of circulating fluid bed airslide disintegrating mill, comprise frame 11, on frame 11, be provided with and pulverize cavity housing 2, pulverize cavity housing 2 and be provided with channelizing island 7 and several pulverizing nozzles 10 in feeder 8, classification motor 1, the chamber, it is characterized in that the upper end of pulverizing cavity housing 2 is provided with grading plant, described grading plant comprises grading wheel 4, grading wheel bearing block 3 and discharge nozzle 6.
The purpose of this utility model can also reach by following measure:
The both ends of described pulverizing cavity housing 2 are curved surface; And pulverize cavity housing 2 and vertically be arranged on the frame 11, it is one rectangular-shaped that its middle part is, and two ends are the hemicycle column, and the diameter of cylinder is identical with the width of cuboid.
The bottom of channelizing island 7 is an arc surface in the described chamber, and the arc surface of channelizing island 7 lower ends is a concentric circle arc plane with the arc surface of pulverizing cavity housing 2 lower ends in the chamber.
2 times waists of the discharging opening of described feeder 8 and the jet of pulverizing nozzle 10 and pulverizing cavity housing tangentially are connected.
Outside front is provided with vertical open and close door 5 on the described pulverizing cavity housing 2, one side of described vertical open and close door 5 is hinged with it by two hinges up and down with pulverizing cavity housing 2, and each limit of all the other of vertical open and close door 5 is provided with some bolts and fixedlys connected with pulverizing cavity housing 2.
Described discharge nozzle 6 is arranged on the top of vertical open and close door 5 and aims on the pulverizing cavity housing 2 at grading wheel 4 centers.
The beneficial effects of the utility model:
The utility model not only effectiveness of classification is higher, the particle that reaches fineness can in time be isolated the High-efficient Production characteristics of main frame, and the air-flow that nozzle discharges hits by comminuting matter probability height, cleaning, easy to use, the utility model is applicable to field of fine chemical, pulverizes production as fields such as medicine, Coating Matting powder, pigment, dyestuffs.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
In Fig. 1 and Fig. 2,1 is the classification motor; 2 for pulverizing the cavity housing; 3 is the grading wheel bearing block; 4 is grading wheel; 5 is vertical open and close door; 6 is discharge nozzle; 7 is baffle in the chamber; 8 is feeder; 9 is arc surface; 10 for pulverizing nozzle; 11 is frame; 12 is gas-distribution pipe.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Circulating fluid bed airslide disintegrating mill of the present utility model comprises frame 11, on frame 11, vertically arranged pulverizing cavity housing 2, the both ends of described pulverizing cavity housing 2 are half cylinder, and central authorities are cuboid, and the diameter of semicolumn is identical with the width of cuboid.Pulverize that cavity housing 2 is provided with in feeder 8, classification motor 1, the chamber channelizing island 7 and several pulverize nozzle 10 evenly distributedly, classification motor 1 is installed in the side of pulverizing cavity housing 2, and the upper end of pulverizing cavity housing 2 is provided with described grading plant and comprises the grading plant of forming by grading wheel 4, grading wheel bearing block 3 and discharge nozzle 6.
The bottom of channelizing island 7 is an arc surface in the chamber, and the arc surface of channelizing island 7 lower ends is a concentric circle arc plane with the arc surface of pulverizing cavity 2 lower ends in the chamber.Like this, make to pulverize in cavity housing 2, grading wheel 4 and the chamber runway of formation one approximate ellipsoidal between the channelizing island 7.Pulverize 2 times waist tangential direction of cavity housing the discharging opening of feeder 8 and the jet of several pulverizing nozzles 10 are set.Outside front is provided with vertical open and close door 5 on the pulverizing cavity housing 2, one side of described vertical open and close door 5 is hinged with it by two hinges up and down with pulverizing cavity housing 2, and each limit of all the other of vertical open and close door 5 is provided with some bolts and fixedlys connected with pulverizing cavity housing 2.Discharge nozzle 6 is arranged on the top of vertical open and close door 5 and aims on the pulverizing cavity housing 2 at grading wheel 4 centers.
