Abstract

The utility model relates to a pulverizer, in particular to a grading system of a pulverizer, which belongs to the technical field of the pulverizer structure. The grading system for the pulverizer is characterized by comprising a grader (9) communicated with a pulverizer crushing area (10), a cyclone separator (8) and a feeder (7) communicated with a feed inlet (11) of the pulverizer. The cyclone separator (8) is connected at the lower part of the grader (9) and the feeder (7) is installed at the lower part of the cyclone separator (8). The grading system for the pulverizer provided by the utility model has reasonable and simple structural design, and solves the problem of high temperature caused by narrow and tight space of current grading system of the pulverizer so that the crushed material is more concentrated and uniform in granularity. The utility model further can improve the work efficiency of the device and prolong the service life of the device.

Description

The flour mill hierarchy system
Technical field
The utility model relates to the hierarchy system of a kind of flour mill, particularly a kind of flour mill, belongs to the flour mill technical field of structures.
Background technology
Existing flour mill structure is as shown in the figure, and its structure and operation principle are following:
Material is admitted to the inner pulverizing district A7 of mill chamber through charging aperture A8.By rotation at a high speed hit post A3 and gear ring A4, be broken into powdery.Simultaneously, under the wind of blower fan, air outside, gets into and pulverizes the district from encircling the leg space ventilation mouth of A2 down through air inlet A1.The material of pulverizing is brought to the graded region A6 of mill lid below under wind action.Under the clasfficiator A5 effect of rotation at a high speed, fine powder gets into next procedure because volume is little, speed is fast, just can pass through clasfficiator.Meal is got back to and is pulverized the district because volume is big, speed is slow, is just got rid of down, carries out secondary and pulverizes.
Repeatedly pulverize and the mobile smooth problem of air because existing flour mill, pulverizing and hierarchy system in a narrow and small confined space, exist, so two shortcomings are arranged: 1) size distribution is concentrated; 2) crush efficiency is low, and the powder delivery temperature is high.
Summary of the invention
The purpose of the utility model is to solve two problems that above-mentioned prior art exists, and a kind of reasonable in design is provided, and grinding particle size distributes and concentrates, ACU temperature, the flour mill hierarchy system that can also increase work efficiency simultaneously.
The utility model is realized through following technical scheme:
The flour mill hierarchy system; Changing existing built-in integral type is outlet structure; Its special character is to comprise clasfficiator 9, cyclone separator 8 that is communicated with flour mill pulverizing district 10 and the drawing-in device 7 that is communicated with flour mill charging aperture 11; The bottom of said clasfficiator 9 is connected with cyclone separator 8, and drawing-in device 7 is installed on the bottom of cyclone separator 8;
Said clasfficiator 9 is communicated with through adapter 5 and pipeline 6 and pulverizing district 10.
The utility model flour mill hierarchy system; Reasonable in design is simple and direct, and it is narrow and small airtight and the high temperature problem that produces is concentrated evenly the raw meal particle size of pulverizing more to have solved existing flour mill hierarchy system space; Can also improve simultaneously the operating efficiency of equipment, prolong the service life of equipment.
Description of drawings
Fig. 1: be prior art flour mill structural representation;
Fig. 2: the utility model external flour mill hierarchy system structural representation.
The specific embodiment
Following with reference to accompanying drawing, provide the specific embodiment of the utility model, be used for the formation of the utility model is further specified.
Embodiment 1
The flour mill hierarchy system of present embodiment is with reference to figure 2; Changing existing built-in integral type is outlet structure; Comprise clasfficiator 9, cyclone separator 8 that is communicated with flour mill pulverizing district 10 and the drawing-in device 7 that is communicated with flour mill charging aperture 11; The bottom of said clasfficiator 9 is connected with cyclone separator 8, and drawing-in device 7 is installed on the bottom of cyclone separator 8; Clasfficiator 9 is communicated with through adapter 5 and pipeline 6 and pulverizing district 10.
The course of work is following:
Material is admitted to the inner pulverizing district 10 of mill chamber through charging aperture 11.By rotation at a high speed hit post 3 and gear ring 4, be broken into powdery.Simultaneously, under the wind of blower fan, air outside is through air inlet 1, and from encircling 2 leg space ventilation mouth down, entering is pulverized and distinguished.Like this, the material of pulverizing just can be under wind action, through take over 5, pipeline 6 is admitted to external hierarchy system.These powders can be divided into by the size of size: meal, than meal and fine powder.
External hierarchy system has clasfficiator 9 and revolves branch separator 8, and powder just earlier through cyclone separator 8, carried out initial gross separation before arriving clasfficiator.The thickest meal under himself weight and action of centrifugal force, will fall into the bottom, and the drawing-in device 7 through the bottom gets into flour mill once more to carry out secondary and pulverize.
Than meal and fine powder, under wind action, get into the graded region at clasfficiator place.This clasfficiator rotates at a high speed under the driving of motor.Because fine powder, volume is little, speed is fast, just can pass through clasfficiator, gets into next procedure.Than meal, because volume is big, speed is slow, just got rid of down, through the drawing-in device of bottom, also get into flour mill and carry out the secondary pulverizing.
Can find out from the present embodiment flour mill course of work,, carry out secondary separation through clasfficiator again then because the material of pulverizing has at first carried out initial gross separation through revolving the branch separator, the material that passes through, size distribution will be more concentrated.And material is pulverized the back and is got into external hierarchy system fast, and the material that is deposited in graded region reduces, and makes the air that carries material, and it is more smooth and easy to flow, and can effectively reduce temperature rise.
