Abstract

The utility model discloses an improved fluidized bed airflow pulverizer which comprises a stander, feeding equipment and a pulverization grading main body, wherein a grading wheel driven through a driving device is arranged on the pulverization grading main body; a plane or a curved surface on which a blade of the grading wheel is placed is a blade surface according to a section graph of the grading wheel, which is obtained along the direction perpendicular to the center rotating axis of the grading wheel; a plane which passes through the center rotating axis of the grading wheel and the geometric center of the blade is a center plane. The improved fluidized bed airflow pulverizer is characterized in that a certain included angle is formed between the blade surface and the center plane. According to the improved fluidized bed airflow pulverizer in the technical scheme disclosed by the utility model, the design of the grading wheel is improved on the basis of the existing fluidized bed airflow pulverizer, so that the rotating speed is reduced by 15 percent on the basis of the original rotating speed; under the same particle size condition, the yield is increased by about 15 percent; under the same rotating speed condition, the fineness of the particle size is reduced by about 18 percent.

Description

A kind of improved fluidized bed air flow crusher
Technical field
The present invention relates to a kind of dry material disintegrating apparatus, be specifically related to a kind of fluidized bed air flow crusher.
Background technology
In the prior art, dry material disintegrating apparatus has two kinds of fluidized bed air flow crusher and horizontal disc type airslide disintegrating mills.The efficiency of fluidized bed air flow crusher is higher, and pulverized particles is thinner, and product quality grade is higher, and its crushing chamber housing is vertical cylinder, and above lower flange connects.The efficiency of Horizontal disc airslide disintegrating mill is lower, and pulverized particles is thicker, and product quality grade is lower.Existing fluidized bed air flow crusher, due to the limitation of grading wheel design, exists, part finished particle unclear to the separation of pulverized particles thickness not go out and still to enter the low situation of situation, crush efficiency that pulverizing chamber is pulverized from discharging opening, haves much room for improvement.
Summary of the invention
The object of the invention is to provide a kind of improved fluidized bed air flow crusher, and it has carried out particular design to the blade design of grading wheel, makes the fineness of rotating speed reduction, output raising, particle diameter less.
In order to achieve the above object, the basic technical scheme that the present invention adopts is: a kind of improved fluidized bed air flow crusher, comprise frame, charging (feeding) equipment, crushing and classification main body, in described crushing and classification main body, be provided with the grading wheel being driven by drive unit, on the sectional view of this grading wheel obtaining along the central rotation axis direction of vertical described grading wheel, the blade place plane of described grading wheel or curved surface are blade face, by plane centered by the central rotation axis of described grading wheel and the plane at described blade geometry center, between described blade face and described central plane, shape forms an angle.The fluidized bed air flow crusher that the technical program limits, on the basis of existing vulcanization bed airslide disintegrating mill, design to its grading wheel improves, make rotating speed from original basis reduce by 15%, under equal particle diameter condition, output improves 15% left and right, little 18% left and right of the fineness of particle diameter under equal speed conditions.
Further, as the further improvement project to above fluidized bed air flow crusher, described angle is that number range is the acute angle of 15 °~25 °.
Again further, according to the fluidized bed air flow crusher of the specific embodiment of the present invention, described angle is 20 ° of left and right.
Beneficial effect of the present invention is as follows:
1. make rotating speed from original basis reduce by 15%, under equal particle diameter condition, output improves 15% left and right, little 18% left and right of the fineness of particle diameter under equal speed conditions.
2. this fluidized bed air flow crusher, by having changed oblique blade grading wheel and original 40% left and right of improving of pulverizing chamber design secondary air device output ratio of particular design from original basis, has been saved energy consumption.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the machine body part of fluidized bed air flow crusher of the present invention.
Fig. 2 is the sectional view of the grading wheel in the specific embodiment of fluidized bed air flow crusher of the present invention.
After reading by reference to the accompanying drawings following detailed description of the preferred embodiment, it will be recognized by those skilled in the art scope of the present invention and realize its additional aspect.
The accompanying drawing that is incorporated in the present specification and forms the part of this description illustrates several aspect of the present invention, and is used for explaining principle of the present invention together with its description.
The specific embodiment
Referring to accompanying drawing 1 to accompanying drawing 2, a kind of improved fluidized bed air flow crusher, comprise frame (attached not shown), charging (feeding) equipment, crushing and classification main body, in described crushing and classification main body, be provided with the grading wheel 1 being driven by drive unit 5, on the sectional view of this grading wheel obtaining along the central rotation axis direction of vertical described grading wheel, the blade place plane of described grading wheel 1 or curved surface are blade face, plane centered by the plane of the geometric center by described grading wheel pivot axis and described grading wheel blade, the blade face of described grading wheel 1 around be parallel to described grading wheel pivot axis blade geometric centre axes rotation and and described central plane between form a sharp angle α.This sharp angle α can be 15 °~25 ° values in number range, comprises numerical value endpoint value.Best, described sharp angle α is 20 ° of left and right.
Dry material enters pulverizing chamber from material inlet 2, Compressed Gas enters particular arrangement four nozzles 3 from entrance spray high velocity air to pulverizing chamber, material accelerates in supersonic jet, and in the repeated stock of pulverizing chamber center intersection, collision, reaches the effect of pulverizing.Pulverized material enters grading room with ascending air, due to grading wheel 1 High Rotation Speed, particle had not only been subject to centrifugal force that grading wheel 1 produces, and but also had been subject to air-flow viscous effect and produces centripetal force in uphill process, the centrifugal force being subject to when particle is greater than centripetal force, inner chamber that particle larger than the Cut size requiring do not enter grading wheel 1 returns to pulverizing chamber and continues to be pulverized, and the particle that reaches Cut size requirement enters grading wheel 1 inner chamber and from discharger 4 outlets, enters gathering-device with air-flow.
The embodiment setting forth above represents and allows those skilled in the art to put into practice necessary information of the present invention, and illustrates and put into practice best mode of the present invention.Once read with reference to the accompanying drawings above description, those skilled in the art just will understand design of the present invention and will recognize the application of these designs of not illustrating especially herein.Should be appreciated that these designs and application fall into this patent openly and the scope of appended claims.
