Abstract
An improved jet mill for a fluidized bed comprises a rack, a grinding cavity connected on the rack, and a grading cavity arranged at the upper part of the grinding cavity and communicated with the grinding cavity, wherein a grading impeller driven by a driving device is arranged in the grading cavity; and the improved jet mill is characterized in that a secondary air inlet is arranged on the grinding cavity. According to the improved jet mill for the fluidized bed, the structure design of the grinding cavity is improved on the basis of the existing jet mill for the fluidized bed, so that the finished products in the grinding cavity can be fully extracted, over grinding phenomenon of the material in the grinding cavity is avoided, and the output is improved by about 25%.
Description
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 of improvement.
Background technology
In the prior art, the dry material disintegrating apparatus has two kinds of fluidized bed air flow crusher and horizontal disc type airslide disintegrating mills.Fluidized bed air flow crusher has independently hierarchy system, and its general function can satisfy the fineness requirement that particle is pulverized, and can satisfy the requirement of pulverized particles adjustable size, powder particle diameter narrow distribution range.The relative efficiency of this type of pulverizer is higher, and pulverized particles is thinner, and the product quality grade is higher, and its crushing chamber housing is vertical cylinder, and above lower flange connects.The efficient of horizontal circle disc type airslide disintegrating mill is lower, and pulverized particles is thicker, and lower grade of product quality.Existing fluidized bed air flow crusher, because dependency structure limitation of design on the crushing chamber, existence is unclear to the separation of pulverized particles thickness, part was can not going out from discharging opening of finished particle and still enters the low situation of situation, crush efficiency that pulverizing chamber is pulverized before entering pulverizing chamber, demands urgently improving.
Summary of the invention
The object of the invention is to provide a kind of improved fluidized bed air flow crusher, and its dependency structure design to crushing chamber has been carried out improving design, and rotating speed reduction, output and efficient are improved.
In order to achieve the above object, the basic technical scheme that the present invention adopts is: a kind of fluidized bed air flow crusher of improvement, comprise frame, be connected in crushing chamber on the described frame, be positioned at crushing chamber top and be attached thereto logical classification chamber, be provided with the classifying turbine that is driven by drive unit in described classification chamber, described crushing chamber is provided with the secondary air mouth.The fluidized bed air flow crusher that the technical program limits, on the basis of existing sulfuration bed airslide disintegrating mill, structural design to its crushing chamber is improved, make the finished product in the pulverizing chamber can obtain fully extracting, avoid material crushing phenomenon to occur in pulverizing chamber, improved about 25% output.
Further, as the further improvement project to above fluidized bed air flow crusher, on the sectional view of this classifying turbine that obtains along the centre rotational axis line direction of vertical described classifying turbine, the plane, blade place of described classifying turbine or curved surface are blade face, plane centered by the plane of the geometric center by described classifying turbine pivot axis and described classifying turbine blade, the blade face of described classifying turbine around the geometric centre axes rotation of the blade that is parallel to described classifying turbine pivot axis and and described central plane between form an acute angle.This fluidized bed air flow crusher improved about 40% originally by oblique blade classifying turbine and the pulverizing chamber design secondary air device PR of having changed particular design from original basis, saved energy consumption.
Further, as the further improvement project to above fluidized bed air flow crusher, described angle is that number range is 15 °～25 ° acute angle.
Again further, according to the fluidized bed air flow crusher of the specific embodiment of the present invention, described angle is about 20 °.
Description of drawings
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 classifying turbine in the specific embodiment of fluidized bed air flow crusher of the present invention.
After reading following detailed description of the preferred embodiment by reference to the accompanying drawings, it will be recognized by those skilled in the art scope of the present invention and realize the aspect that it is additional.
In this manual combined and accompanying drawing that constitute the part of this specification illustrates several aspect of the present invention, and is used for explaining principle of the present invention with its description.
The specific embodiment
Referring to accompanying drawing 1 to accompanying drawing 2, a kind of fluidized bed air flow crusher of improvement, comprise frame (not shown in the accompanying drawing), be connected in crushing chamber on the described frame, be positioned at crushing chamber top and be attached thereto logical classification chamber, be provided with the classifying turbine 1 that is driven by drive unit 6 in described classification chamber, the below of material inlet is provided with secondary air mouth 4 on the described crushing chamber.The fluidized bed air flow crusher that the technical program limits, on the basis of existing sulfuration bed airslide disintegrating mill, structural design to its crushing chamber is improved, make the finished product in the pulverizing chamber can obtain fully extracting, avoid material crushing phenomenon to occur in pulverizing chamber, improved about 25% output.The classifying turbine 1 by drive unit 6 drivings that the crushing chamber top arranges, as shown in Figure 2, on the sectional view of this classifying turbine that obtains along the centre rotational axis line direction of vertical described classifying turbine, the plane, blade place of described classifying turbine 1 or curved surface are blade face, plane centered by the plane of the geometric center by described classifying turbine pivot axis and described classifying turbine blade, the blade face of described classifying turbine 1 around the geometric centre axes rotation of the blade that is parallel to described classifying turbine pivot axis and and described central plane between form a sharp angle.This sharp angle can be 15 °～25 ° values in number range, comprises the numerical value endpoint value.Best, described sharp angle is about 20 °.
Dry material enters pulverizing chamber from material inlet 2, Compressed Gas advances particular arrangement from entrance four nozzles 3 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, because classifying turbine 1 rotation at a high speed, particle not only had been subjected to centrifugal force that classifying turbine 1 produces, but also has been subjected to the air-flow viscous effect and produces centripetal force in uphill process, the centrifugal force that is subjected to when particle is greater than centripetal force, namely the particle bigger than the Cut size that the requires inner chamber that do not advance classifying turbine 1 returns pulverizing chamber and continues to be pulverized, and the particle that reaches the Cut size requirement enters classifying turbine 1 inner chamber and enters gathering-device with air-flow from discharger 5 outlets.
The embodiment that sets 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.In case read above description with reference to the accompanying drawings, 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.
