Specific implementation process is as follows:
Micro-nano powder material to depolymerization has previously been stored in feed bin 101, micro-nano powder after punishment in advance Weighing,
It is input to hot wind transfer tube 2 by doser 103, micro-nano powder is empty with the heat of 60-320 degree in hot wind transfer tube 2
Gas mixing, micro-nano powder are transferred to drying chamber 301 while heating.
Be provided in the drying chamber 301 of depolymerization mechanism 3 break up wheel 304 pairs of micro-nano powders carry out breaing up depolymerization, break up wheel
304 purpose is to interrupt the hydrogen bond of nanoparticle surface, the wet bridge of absorption and other chemical bonds, prevent particle and particle it
Between stick aggregation mutually, in subsequent depolymerization chamber 302 depolymerization crushing basis is provided.Due to breaing up the centrifugal action of wheel 304, group
Poly- bulky grain movement is got rid of to the periphery of drying chamber 301, and the powder of refinement close to 301 center of drying chamber and is transferred to depolymerization
Chamber 302.Should during, since powder is constantly broken up and depolymerization, powder surface product is continuously increased, thus powder and hot-air it
Between contact surface be gradually increased, greatly improve drying efficiency, reduce drying cost.
Powder after being refined heating enters depolymerization chamber 302, and depolymerization chamber 302 is provided with several wind wheels 305, in wind wheel 305
Between be provided with isolation board 307, the effect of isolation board 307 is to prevent powder disordered motion, and the powder of not depolymerization is avoided to enter packet
Cover chamber 303.Powder, which enters after depolymerization chamber 302, to be directed to disk 308 and is directed in material path as defined in depolymerization chamber 302, and powder is in material path
In spin and move upwards around wind wheel 305, since the wind piece high speed rotation on wind wheel 305 brings powerful wind pressure, air-flow pressure
Urgent powder enters in the saw-tooth grooves inside sleeve 306, and 305 wind piece high speed rotation of wind wheel forms a positive pressure to material path, single
The micro-nano powder of particle is suspended in inside the hot-air of positive pressure, is further heated and is dried, therefore can guarantee micro-nano
Powder water content is lower than within 5/10000ths.306 groove of sleeve is the zigzag of special designing, and wind wheel 305 is transported along sawtooth inclined-plane
Dynamic, in the cyclone of sawtooth faced directly and form a rotation inside groove, the powder broken up without depolymerization is due to gravity, quilt
The air-flow that wind wheel drives, which is pressed in always in the cyclone inside 306 groove of sleeve, to be rotated, since wind wheel 305 and wind piece are that high speed is revolved
Turn, and the powder of reunion is static, the rotary motion of a movement and stationary object fluid mass, will be formed in " whirlpool ", air is dynamic
Mechanics scientist's image describes it as " tendon of fluid motion ", because fluid cannot stand stranding, once having rubbed whirlpool, here
" stranding " refers to the shearing force acted on micro-nano powder agglomerated particle.305 wind piece of wind wheel is according to 50-160 meter per second linear velocity
Operation can drive powerful air stream, allow reunion powder granule to rest on inside the special groove set of sleeve 306, reunion powder
Body particle is rubbed open into individual particle rapidly by stream pressure, shearing force, frictional force, centrifugal force and reverts to initial size, micro-nano
Powder is carried over depolymerization chamber 302 during stranding and rotation, in fluidized state.
Should during, irregular micro-nano powder spiral and constantly rubs in material path with sawtooth, micro-nano rice flour
External week, sharp water chestnut was modified, powder is shaped to the particle of an almost spherical, while micro-nano having lattice crackle
Also it is interrupted tearing, powder granule can be effectively prevented in cladding or the table not coated is left or newly formed to use process
Face, the efficiently comprehensive surface modification for completing micro-nano powder.
Functional chemical drug covering is stored in the inside of covering storehouse 401, and covering claims 402 according to micro-nano powder object
The weight of material is matched and is transported to atomizer 403, and covering is inputted in 403 the inside of atomizer through air-pressure duct 404
Compressed air blow and hit to form high-frequency vibration, be injected into the material path of cladding chamber 303 so that covering is atomized into droplet.Compression
Covering after the positive pressure of air will be atomized sprays into cladding chamber 303, wherein and the setting of covering entrance generally circumferentially cuts money,
Covering injection direction is the direction of rotation of face wind wheel wind piece, after being atomized modified covering agent penetrating cladding 303 material path of chamber, with
Micro-nano powder relative motion after depolymerization, while unimolecule particle is gasificated by hot-air, at boiling after dispersing with complete depolymerization
It is soaked after rising the opposite collision of micro-nano granules of shape, the physics and chemisorption dependent on organic coating agent in particle surface are made
With, covering micro-nano granules surface formed even compact clad (physical absorption mainly pass through covering and particle it
Between pass through the physical actions such as electrostatic attraction；Chemisorption is mainly the chemistry utilized between the functional group of particle exterior surface and covering
Reaction realizes that surfactant coats the surface of particle) to complete the entire cladding of micro-nano surface.
Wherein, it can change the function of micro-nano powder material by entry position and quantity that different coverings are arranged,
1 or more covering entrance generally can be set, while applying different types of covering, be sequentially completed different coverings
Cladding, reaches new material special requirement and purpose.
Finally, complete cladding powder by discharging mechanism 5 collect store, micro-nano powder in sequence by drying, depolymerization,
Final products are formed by the collection of discharging mechanism 5 after the cladding of surface.
