More particularly to a kind of colliding-type air-flow mill.
Background technology
In normal operation, the airflow milling material to be crushed adds conventional airflow milling through raw material cabin, compressed air
Supersonic airstream is formed in the presence of nozzle through nozzle, material is accelerated, material shears collision and reaches powder each other in mill chamber
Broken purpose, the material after crushing reach grading wheel with ascending air, and grading wheel carries out granularity using semi-free vortex principle to material
Sorting, the material for reaching granularity requirements is followed by cyclone separator progress powder collection by being classified to enter, and fails to reach granularity
It is required that powder be graded wheel ejection return mill chamber continue to crush.But existing airflow milling is frequently switching on the situation of machine
Under, it may appear that problems with：During normal shutdown, it is desirable to tell the material in mill chamber only, if as material is not told only, in mill chamber
Under pressure effect, in the nozzle that the powder in mill chamber can inversely enter, it can be sprayed in next process with supersonic airstream,
Wear-out failure can be carried out during this to nozzle, and nozzle once has concentrated wear, can form supersonic airstream in abrading section
Local turbulent, the nozzle curve damaged originally is caused further to damage, and then form supersonic gas sword, nozzle is broken
It is bad, and then reduce crush efficiency；Material must be told after it requires shutdown, but telling material while material in mill chamber will all enter
In cyclone collector below, wherein there is a large amount of powders not sorted through grading wheel, do not reach the quality requirement of powder finished product,
Pollution can be caused to cyclone separator below.
The content of the invention
The utility model is mainly to solve the technical problem present in above-mentioned prior art, there is provided a kind of collision type air-flow
Mill.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of collision type gas
Stream mill, including feed bin, feed bin lower section, which is fixedly mounted, tilts conveying pipeline, tilts conveying pipeline to be obliquely installed, inclination conveying pipeline and water
The inclination angle of plane is 45-60 °, tilts and butterfly valve is fixedly mounted among conveying pipeline, tilts conveying pipeline and is fixedly connected with particle storehouse, its

All it is used to control discharge with the second discharge valve；Vacuum feeding device is fixedly mounted on vacuum feed bin, vacuum feeding device includes
The components such as magnetic valve, strainer valve, blowback drum, are fixedly mounted vacuum connection tube on vacuum feeding device, vacuum connection tube with it is true
Empty conveying and connection；Rotary cylinder is fixedly mounted in vacuum feed bin lower end, and rotary cylinder is fixedly connected with feed bin, makes feed bin, vacuum
Feed bin, particle storehouse etc. forms a loop；Conveying storehouse is fixedly mounted on particle storehouse, grading wheel, classification are fixedly mounted in conveying storehouse
Wheel one end is connected with cyclone separator, the grading wheel other end and motor connection；The first discharge valve and second in normal work
Discharge valve is closed, and when needing to tell material, the first discharge valve and the second discharge valve opening, make the material in particle storehouse through defeated
Expects pipe is returned in vacuum feed bin；And one rotary cylinder of original feed bin top increase, a vacuum feed bin, a set of vacuum are defeated
Device is sent, in normal operation, vacuum available charging；In discharging, material in script particle storehouse can be passed through the system
It is unloaded in feed bin, avoids and the problem of material in nozzle after shut down be present, increases the service life of nozzle.
Further, nozzle sets 3 altogether, and nozzle is uniformly arranged on the bucket wall of particle storehouse lower end, and all nozzles are arranged on
In same level, nozzle includes air inlet and gas outlet, Lavalle spout being set in air inlet, increases the crushing effect of material
Fruit.
Compared to the prior art, on original feed bin top the utility model increases a rotary cylinder, a vacuum material
Storehouse, a set of vacuum transportation device, in normal operation, vacuum available charging；, can be by thing in script particle storehouse in discharging
For material by the system uninstallation to feed bin, avoiding and the problem of material in nozzle being after shut down present, increase nozzle uses the longevity
Life.
