Abstract

The utility model relates to a crusher, and in particular to a multiple circulating air flow crusher. The crusher comprises a frame which is provided with a crushing cavity. A particle classifier is arranged on the upper part in the crushing cavity and a guide island is arranged at the bottom of the crushing cavity. A plurality of crushing air flow nozzles are arranged at the lower end of the crushing cavity, wherein one of the nozzles is provided with a feeder which is connected with a raw material box through a pipeline. A guide sieve device is arranged at the air flow inlet of the particle classifier. A secondary air flow crushing device is arranged at the air flow outlet of the particle classifier. When the air flow crusher provided by the utility model is used to crush materials, the air flow crusher is helpful for improving the crushing purity. The particle classifier is fed by way of rotatable air, so that large particle materials are prevented from entering, and fine particle materials enter along with the rotate air. Therefore, the crushing grade of the product is improved, and the raw materials are crushed more thoroughly.

Description

The circulating airslide disintegrating mill of a kind of final election
Technical field
The utility model relates to a kind of pulverizer, specifically the circulating airslide disintegrating mill of a kind of final election.
Background technology
Airslide disintegrating mill is to utilize high velocity air to realize the fine equipment of dry type material fining.This equipment surrounding is provided with the high pressure admission nozzle of arranging in opposite directions, penetrates from nozzle through purifying with dry compressed air, forms high velocity air.Material bumps at high velocity air intersection point center, is pulverized in moment.Particle through pulverizing rises to grading room with air-flow, and qualified particle enters cyclone separator with air-flow, finally obtains required product.That airslide disintegrating mill has is simple in structure, milling product superfine and purity is than advantages of higher, has obtained using more and more widely in a plurality of fields.But the airslide disintegrating mill that uses at present mostly bulky, pipeline is complicated and because its dust discharge difficulty causes this equipment working environment also relatively poor greatly.In addition, existing pulverizer is because the impact that can only rely on gas is pulverized with the realization of mutual friction mutually in the middle of powder, then rely on particle effect of centrifugal force in rotary course to select bulky grain, such mode can be used in the larger material of proportion, the material that some proportions are lighter in situation about being more or less the same due to granular size, only utilizes centrifugal force to separate also and can not thoroughly separate, make in the powder of ejection and contain the bulky grain of super scope, and affect product quality.
Summary of the invention
The purpose of this utility model is exactly the problem that exists for solving prior art, and has designed the circulating airslide disintegrating mill of a kind of final election, realizes oarse-grained thorough powder, increases crushing effect.
The technical solution of the utility model is: the circulating airslide disintegrating mill of a kind of final election, comprise frame, the pulverizing cavity is installed on frame, the crushing chamber internal upper part is provided with grain classifier, the bottom is provided with channelizing island, the lower end of crushing chamber housing is provided with several and pulverizes air current spray nozzle, one of them nozzle is provided with feeder, and feeder is connected with material box by pipeline, and the air flow inlet place of described grain classifier is provided with the diversion screen screening device; The air flow outlet of grain classifier is provided with the secondary gas flow reducing mechanism.
Described diversion screen screening device comprises bar shaped filter and drainage plate.
Described secondary gas flow reducing mechanism comprises the separating twice nozzle that is fixed on the crushing chamber housing, and described jet expansion is mutually vertical corresponding with the inclined-plane of channelizing island.
Described grain classifier is to be evenly equipped with the transfer roller of a plurality of ventilation through holes on circumference, and the air vent porch of transfer roller is fixed with the flabellum of inclination.
The beneficial effects of the utility model can draw by such scheme: owing to adding the bar shaped filter in crushing chamber, make material carry out the physical filtering powder, not only realize the effective powder of bulky grain and magazine, and can make air turbulence, it is more thorough that material clashes into pulverizing mutually.When utilizing airslide disintegrating mill that the utility model proposes to carry out crushing material, the pulverizing purity that improves material is had very great help.And grain classifier adopts the charging of convolution wind, more can stop large granular materials and enter, and only has the fine particle material to circle round with the wind and enters, and has improved the pulverizing grade of product, makes pulverizing more thorough.This shows, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Wherein, 1 is grain classifier, and 2 is the crushing chamber housing, and 3 are the bar shaped filter, and 4 is channelizing island, and 5 is frame, and 6 is compression gas tank, and 7 is material box, and 8 is charge pipe, and 9 for pulverizing air current spray nozzle, and 10 is the separating twice nozzle, and 11 is drainage plate.
The specific embodiment:
In order to understand better the utility model, explain in detail embodiment of the present utility model below in conjunction with accompanying drawing.
The specific embodiment: the circulating airslide disintegrating mill of a kind of final election, comprise frame 5, frame lower is provided with compression gas tank 6, the pulverizing cavity is installed on frame 5, crushing chamber housing 2 internal upper parts are provided with grain classifier 1, the bottom is provided with channelizing island 4, the lower end of crushing chamber housing 2 is provided with several and pulverizes air current spray nozzle 9, is communicated with charge pipe 8 on one of them nozzle, and charge pipe is connected with material box 7.The air flow inlet place of grain classifier 1 is provided with bar shaped filter 12 and drainage plate 11.The air flow outlet of grain classifier 1 is fixed on crushing chamber housing 2 and is provided with separating twice nozzle 10, and the spout of separating twice nozzle 10 is mutually vertical corresponding with the inclined-plane of channelizing island 4.Grain classifier 1 is for being evenly equipped with the transfer roller of a plurality of ventilation through holes on circumference, the air vent porch of transfer roller is fixed with the flabellum of inclination.
Above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
