The principle of the present invention and the course of work：
Abrasive body is solid phase movement in the cylinder of tube mill, and acting in cylinder for material wind-engaging is vapor phase movement,
Material movement in cylinder is to blow material by wind.The partition panel of two phase flow partition device for barn of the present invention uses solid annular plate,
Material and wind are only capable of from the through hole among partition panel by utilizing " Bai Nuke principles "：The small local flow velocity of sectional area is pressed soon
Power is low, and the slow pressure of the big local flow velocity of sectional area is high.
Material is brought into cylinder by wind when wind and material are transported at feed inlet by feed arrangement, due to compartment
Partition panel centre on combination unit is through hole, surrounding is fan-shaped solid slab, and wind and material can only be led to by the center of partition panel
Hole enters next storehouse, and the sectional area of the intermediate throughholes of feed inlet and two phase flow compartment combination unit is small, by the wind speed of wind it is fast,
Pressure is low；And the sectional area of warehouse is big, storehouse indoor air velocity is slow, pressure is big, and pressure differential, pressure general goal are just formed so in warehouse
Wind will be flowed to the small place of pressure, circulation vortex is eventually formed in warehouse.Material into warehouse is involved in circulation by wind
In vortex, vortex is convolution wind, and convolution wind is blown from rear end forward end, and material will constantly be rotated with rotating vortex, revolved
Ground during turning with abrasive body contact-impact.When material is bulky grain since material can not be blown into by weight maelstrom
Next storehouse, such material just in vortex iterative cycles grind, when material be ground (material weighs in itself when reaching certain fineness
Power is less than wind-force) next storehouse is blown into regard to wind can be vortexed, the preceding storehouse wind-force being blown into from feed inlet due to wind is always greater than rear storehouse wind
Power and every piece of partition panel are that centre has the solid without seam of combing of through hole, therefore vortex can be produced in each warehouse, therefore entrance
The material in next storehouse may proceed into circular grinding in the circulation vortex of the warehouse until fineness of materials reaches and is blown into next storehouse
Weight when can just be vortexed wind and bring next storehouse into, so circulation is until material reaches requirement fineness and can just be taken out of cylinder 1 by wind
Discharged via drawing mechanism.
Since partition panel center is through hole, intelligent two phase flow tube mill is to be constantly in rotation status in the course of work, preceding
The material or abrasive body in storehouse can inevitably be got rid of in rotating cylinder out of partition panel through hole into rear storehouse, thus every
A bar shaped grid screen plate is installed in the front end of storehouse plate, is on the one hand used to prevent the abrasive body in preceding storehouse or material from entering Hou Cang and making
Bunchiness storehouse, is on the other hand used to filter the material after grinding.Due to the bar shaped grid set by the first warehouse to last warehouse
The bar seam spacing of sieve plate is gradually reduced, i.e., the distance on the bar shaped grid screen plate that preceding storehouse is installed between two neighboring bar shaped always greater than
Distance on the bar shaped grid screen plate of storehouse installation between two neighboring bar shaped afterwards, makes material still can be by its storehouse after next storehouse is entered
Interior bar shaped grid screen plate stops.
The present invention can also the front-end and back-end of cylinder install wind pressure sensor, the wind pressure sensor also with air-blower control
Case connects.On the one hand wind pressure sensor can monitor the wind pressure by tube mill in real time, on the other hand can be according to material requirement
Fineness adjust the wind speed by tube mill wind, when needing the material of fineness of grind higher, wind pressure sensor sends signal wind
Adjusting mechanism in machine control cabinet, which is reacted, heightens wind-force, and conversely when needing grinding material fineness low, wind pressure sensor is sent out
The adjusting mechanism gone out in signal fan control box is reacted wind-force tune is low, can be made respectively by the wind speed in application cylinder body
The increase of storehouse circulation strength of vortex reduces, both growths or shortening of material milling time, it is possible to the thin of material requirement is ground
Degree, can also be ground superfine powder, nano powder.
