Abstract
The utility model relates to a crushing and grading device for air flow crusher apparatus, which comprises a grader, a crushing chamber, etc. The utility model is characterized in that the feeding part at the lower end of the grader is fixed with a circular hollow cavity whose lower end is provided with an independent ascending air pipe that is communicated with a crushing chamber, and the both ends of the crushing chamber are provided with a high speed jet nozzle which is situated in an air return pipe whose inlet is communicated with the coarse powder discharge outlet of the grader. The utility model has the advantages of simple structure and favorable effects of crushing and grading.
Description
The utility model relates to a kind of pulverizing and grading plant of airslide disintegrating mill.
The pulverizing chamber of existing airslide disintegrating mill and the passage of clasfficiator are same cavitys.High-speed jet enters pulverizing chamber, drives the powder knock against each other, and the thickness mixed powder that is produced is that ascending air brings to clasfficiator.Fine powder enters clasfficiator, and meal is discharged by clasfficiator, returns to cavity.Therefore, the cavity on the pulverizing chamber is the shared same passage of ascending air and decline meal, influences grading effect.
The purpose of this utility model is exactly the shortcoming that overcomes said apparatus, and the pulverizing and the grading plant of the airslide disintegrating mill of a kind of simple in structure, classification and good crushing effect is provided.
The purpose of this utility model is achieved in that
Device of the present utility model comprises clasfficiator and pulverizing chamber, wherein clasfficiator comprises the rotation classifying turbine, vessel shell, centre rotational axis, the rotation classifying turbine is fixed on the rotating shaft that is positioned at the vessel shell center, there is the high pressure gas inlet vessel shell upper end, there are one or more annular slots or hole in rotation classifying turbine lower surface, be provided with a kuppe below the rotary blade, it is characterized in that, clasfficiator lower end center fixation one ring cavity, the cavity lower end is provided with the ascending air pipeline, and the ascending air pipeline communicates with pulverizing chamber, the two ends of pulverizing chamber are provided with the high-speed jet nozzle, and be connected with the Returning flow pipe, the import of Returning flow pipe is connected with the meal outlet of clasfficiator again, and the opposite side of Returning flow pipe is provided with feed pipe.
At the porous plate that the one or more annular slots or the place, hole (being the air inlet of clasfficiator) of this clasfficiator are coated with one or more ring-types or other shape, many apertures can be clear openings on these porous plates, also can be oblique through holes.This porous plate also can be fixed on the ring cavity, ascending air carries the thickness powder and enters ring cavity by pipeline, enter classifying turbine by porous plate again, fine powder comes out to enter gatherer by the clasfficiator middle part, meal enters pulverizing chamber with Returning flow by Returning pipe, and the high-speed jet nozzle places Returning flow.
This device can use the classification rotary blade more than 1 or 1.When using a rotary blade, Returning flow be divided into two the road or multichannel enter pulverizing chamber, every Lu Youyi high-speed jet nozzle.When using a plurality of rotation classifying turbine, each classification rotary blade all has independently ascending air pipeline and independently Returning flow pipeline, and these pipelines all come together in pulverizing chamber, and a high-speed jet nozzle is all arranged in entering the Returning flow pipeline of pulverizing chamber.
The utility model has the advantages that: simple in structure, classification and good crushing effect.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a kind of structural representation of the present utility model;
