Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
It is to be appreciated that drawings and embodiments are merely to make those skilled in the art be fully understood by the technical program, and
Can implement, therefore not draw in strict accordance with the mode of Graphing of Engineering in accompanying drawing is drawn, only carry out schematic illustration,
For convenience of presentation technology details in width figure, the size of concrete part has zooming in or out of suitability, and for this
Known to skilled person, content is necessarily omitted.
As it is shown in figure 1, a kind of spray drying tower for architectural pottery preparation with clad powder particles, including tower body
1, the air-intake device 2 being arranged at top of tower, the extractor fan 3 being arranged at tower side wall lower end, be arranged at the discharging opening 4 of tower bottom with
And it is arranged at the slurry sprayer unit 5 between described air-intake device 2 and described extractor fan 3 with the distribution of tower body center array, also
Including the covering liquid sprayer unit 6 being arranged between described air-intake device 2 and described slurry sprayer unit 5.
This utility model is provided with covering liquid by increasing between described air-intake device 2 and described slurry sprayer unit 5
Sprayer unit 6, therefore makes in the preparation process of ceramic powder granule, and described covering liquid device 6 has high bonding for injection
Property, the covering liquid of high intensity, described slurry sprayer unit 5 is for spraying the slurry that known ceramic material is prepared, described bag
Covering liquid mist and drip with slurry droplet under the effect of the high-temp. vortex of described air-intake device 2, both are formed xeraphium granulation in tower
Coated particle and pulp particle, and owing to coated particle is distributed in the top of pulp particle, acted on to lower air pressure by tower
Under, described coated particle is during falling, and the surface that can be uniformly wrapped on described pulp particle forms cancellated bag
Coating, finally acquisition has the ceramic powder granule of clad and discharges through described discharging opening 4.
It is high that described spray drying tower effectively solves preparation cost in the technology of preparing of existing building ceramic powder granule
Problem, not only saves preparation section, easy and simple to handle, cost-effective, and have that granulating and forming speed is fast, pelletize quality and effect
The feature that rate is high；The ceramic powder grain structure being prepared into by existing spray drying tower, surface does not has integument；And by this practicality
Novel described spray drying tower preparation has the ceramic powder grain structure of clad, has uniform integument；I.e. by spraying
Ceramic powder granule prepared by mist drying tower, defines ganoid clad, makes described ceramic powder granule possess more
Different performances, covering liquid covered effect is good, ceramic grain surface is smooth, mobility increases, to ceramic powder particle surface
Burr plays a very good protection, so that when being pressed into brick, reducing burr damaged, saves material, preparation high efficiency；
And the quality improving ceramic powder granule differs, is distributed rambling situation so that the ceramic tile surface effect being prepared into
More preferable, base substrate is unlikely to deform and ftractures.
Further illustrating, described slurry sprayer unit 5 includes slurry jet pipe 51 and slurry nozzle 52, described slurry jet pipe 51
One end in tower wall, connect slurry nozzle 52, slurry is pressed into described slurry jet pipe 51 by power set, and by described slurry
Nozzle 52 sprays in tower, as in figure 2 it is shown, described slurry nozzle 52 becomes 35～65 ° of angle A obliquely, described slurry nozzle with tower wall
The aperture of 52 is 2.8～3.5mm.
Owing to ceramic size is to enter in tower body from described slurry jet pipe 51, and spray through described slurry nozzle 52,
During whitewashing, along with the change of temperature, often there will be at described slurry nozzle 52 because temperature reduction makes slurry condense
Causing the situation of blocking, therefore, described slurry nozzle 52 becomes 35～65 ° of angle A obliquely, the hole of described slurry nozzle 52 with tower wall
Footpath is 2.8～3.5mm, when quitting work, makes the leftover slurry in tube wall and nozzle reflux, effectively prevents slurry nozzle 52
Blocking, has saved maintenance and disposal costs.
Further illustrating, described covering liquid sprayer unit 6 includes covering liquid jet pipe 61 and covering liquid nozzle 62, described cladding
One end of liquid jet pipe 61 connects covering liquid nozzle 62 in tower wall, and covering liquid is pressed into described covering liquid jet pipe by power set
61, and sprayed in tower by described covering liquid nozzle 62, described covering liquid jet pipe 61 outer sheath is provided with steam pipe 63, between the two shape
Becoming heat-insulation layer, the aperture of described covering liquid nozzle 62 is 1.0～2.0mm.
Owing to described covering liquid is to enter in tower body from described covering liquid jet pipe, and spray through described covering liquid nozzle,
In tower, heated drying forms coated particle and uniform adhesion is coated on pulp particle surface, and the most described covering liquid is intended to have height
Caking property, heat-insulation layer is set outside covering liquid jet pipe 61, can effectively prevent covering liquid from boning because of variations in temperature, and will
The aperture of described covering liquid nozzle 62 is set to 1.0～2.0mm, i.e. less than the aperture of described slurry nozzle 52, thus realizes bag
The covered effect covering granule is good, distribution more uniformly, density more reasonable, make dried granular mass more excellent.
Further illustrating, the quantity of described slurry sprayer unit 5 is 2 or more than 2.
Under controlling the effect degree of high-temp. vortex of described air-intake device 2, increase slurry in described spray drying tower
The quantity of sprayer unit 5, can be effectively improved the drying efficiency of slurry, thus improve preparation efficiency and the preparation benefit of powder.
Preferably, the aperture of described covering liquid nozzle 62 is 1.5mm.
Form coated particle in spraying into described spray drying tower due to covering liquid with covering liquid droplet, control covering liquid nozzle
Pore size, thus control the size of coated particle so that it is be more beneficial for being coated on pulp particle surface, covered effect
More uniform, density is more reasonable, and structure is more stable, it is to avoid described pulp particle and coated particle occur when punching press is suppressed
Desorption.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
By novel principle, and the restriction to this utility model protection domain can not be construed to by any way.Based on explanation herein,
Those skilled in the art need not pay performing creative labour can associate other specific embodiment party of the present utility model
