Description
Technical field
The invention belongs to solid particle（Hereinafter referred to as particle）Classification（Size particles are separated）Technical field, it is adaptable to need
Industry, the field that solid particle is separate, such as（It is not limited only to this）：Cement, steel, fertilizer, feed, building materials, energy etc..
Background technology
The present invention is solid particle（Hereinafter referred to as particle）Classification（Size particles are separated）Technology, it is adaptable to need solid
Industry, field that particle is separate, such as（It is not limited only to this）：Cement, steel, fertilizer, feed, building materials, energy etc..
In above-mentioned field, solid particle is given by particle size during generally requiring involved physics, chemistry
Separate, traditional method is carried out by the way of screening or special external seperator, is had the disadvantage：Long flow path, investment are big, energy consumption
High, process is relative complex.And it is larger by pellet moisture levels, viscosity influence, cause to be restricted using scope and effect.
By taking traditional fertiliser granulates production as an example：In production different size of particle the comminutor of revolving body, drying machine,
Cooler to outlet end motion, it is necessary to classification solid particle, it is necessary to by screening be put into next procedure, by a series of
Subsequent handling obtains grain products.
Refer to the attached drawing 1, it is necessary to the particle of processing enters from particle process equipment one end, gas with holding addition, in particle plus
Required processing is carried out in construction equipment rotary body 1, for example：Granulation, dry, cooling, blowing etc., the particle of the mixing particle diameter after processing
Into mixing particles discharge bucket 2, screening machine 3 is entered back into, separate large or fine granule by the screen cloth of screening machine, fine grained enters
Enter fine grained hopper 4 as material return system is returned, start anew to re-work together with raw material, coarse granule enters following process
Operation is until be the product for needing, particle process equipment tail gas out, into exhaust treatment system, until qualified discharge.
The shortcoming of the technology：The particle of the mixing particle diameter the 1st, without classification sets from the revolution such as comminutor, drying machine, cooler
In standby out after, it is necessary to increase external device, increase investment, increase energy consumption, increase and take up an area, increase dust when by screening
Effusion, increase noise；Because mesh size is tiny when the 2nd, due to screening fine powder, cause fine-powder bed net efficiency to decline, cause opposite
The influence of product；3rd, when sieving surface moisture or there are the granule materials of viscosity, screen cloth is easily pasted, is generally required granule materials
Pre-processed, such as cool, surface face powder etc., adds additional energy consumption and operation.
The content of the invention
The purpose of the present invention is directed to drawbacks described above, and a kind of gas method particle separation method for proposing, i.e., in mistake
Increasing and change partial component among journey equipment can just reach the purpose for separating and being classified.
To need that the particle surface for separating mixing particle diameter is dry, have certain humidity, have one present invention mainly solves above-mentioned
Determine the screening problem of viscosity, such as hot screening problems faced：Necessary component will be set in turn-around machine, using gas and material
The effect of curtain, most of not meeting directly is completed in the said equipment needs the fine grained of particle diameter to separate, and it is directly returned into life
Product system, to solve problem present in above-mentioned conventional method.
Main technical schemes of the invention：Gas method particle separation method, it is characterized in that turning using apparatus for rotating
Dynamic and lifting flight is kicked up granule materials in revolution, and according to large or fine granule, move distance is different in gas, by gas
Kinetic energy acts on granule materials, so as to realize the most separation of large or fine granule in apparatus for rotating.
Usually, separation method of the present invention includes that particle processing sets by being carried out with lower separation device, mainly
Standby rotary body, gas feed is provided with the material upstream end of rotary body, and some lifting flights, rotation are set in the cylinder of rotary body
The port of export of body is provided with discharge component.
Preferably, a rotating body of the present invention is additionally provided with inner barrel, and inner barrel is provided with inner barrel lifting flight.
Further, the present invention can be provided with cone, circle baffle plate of the material by function in the front end of inner barrel
Or several piece circle baffle plate or several piece spiral plate, material is by locating some oblique flights of setting or spiral flight.
Preferably, discharge component of the invention can be received from and the hopper of dropping material, including coarse granule discharge bucket
With fine grained discharge bucket.
Further, discharge component of the invention can also be the structure for carrying lifting function to change discharging direction and position
Part, the component is made up of the cavity of several quantity, is fed by side or inner side top surface, is discharged by rotary body outside.
The present invention is kicked up granule materials using the rotation and flight of apparatus for rotating in revolution, according to large or fine granule in gas
Middle move distance is different, and granule materials are acted on by the kinetic energy of gas, so as to realize that large or fine granule is most of in apparatus for rotating
Separation, so as to meet production needs.
Beneficial effects of the present invention：
1st, completed in equipment because large or fine granule is separated, it is not necessary to screening plant, do not increase power-equipment, simple flow and subtracted
Few equipment, takes up an area, save energy so as to reduce investment outlay and not have, while the noise and airborne dust of screening plant are it also avoid, at one stroke
Many.
2nd, the method for using gas separate, it is ensured that the primary characteristic of material is constant, than if maintaining temperature-resistant.
3rd, using the method in gas apparatus separate, there is no screen cloth, it is to avoid the blocking of screen cloth mesh especially dusting cover mesh,
It is suitable for the separation of fine particle.
4th, using the method in gas apparatus separate, there is no screen cloth to paste sieve problem, be adapted to the particle of certain wetness
There are certain viscous feed separation, better adaptability with surface.
