Description
Technical field
The present invention relates to a kind of ceramic tile strip shaped grain granulation method and equipment.
Background technology
All the time, Imitation Rock Porcelain Tiles, especially the imitative stone material of polished brick in porcelain character is its important exploitation direction.A lot of stone materials need add certain particle and just can reach imitation effect true to nature in ceramic tile or polished brick in porcelain character.The Imitation Rock Porcelain Tiles of having derived thus granulating technique.The tradition granulating technique can prepare the particle of sheet, approaching circle, irregular polygon.And strip shaped grain often appears in the stone material, this particle is the important element that stone material constitutes.Therefore, if the ceramic tile industry can prepare the particle of strip, will be one to the imitative stone material of ceramic tile and promote greatly.
Summary of the invention
The purpose of this invention is to provide a kind of method and apparatus for preparing the ceramic tile strip particle, prepared strip shaped grain mixes with ceramic brick powder lot with certain proportion that to be suitable for Ceramic Tiles dry-pressing formed.
Present device can utilize existing vacuum deairing machine to be transformed.With sheet iron the vacuum deairing machine outlet is shut, bore a round, hole centre distance is greater than 8mm, and bore dia is no more than 10mm, uses the Frequency Converter Control extruded velocity, i.e. main shaft 8 rotating speeds (seeing schematic diagram 1).
The object of the present invention is achieved like this; at first preparing the moisture content percentage by weight is the plastic pug of 18-23; the material of plastic pug; it can be Imitation Rock Porcelain Tiles; it also can be the low temperature material; pug adds vacuum deairing machine; under suitable pressure effect, from the hole, extrude; the mud bar of extruding drops on the belt under the protection of micro mist; the tray dried of packing into; its moisture content percentage by weight of control 6-12 after the mud bar drying crosses 20 mesh sieves with the micro mist sieve down, and the mud bar fragments into the microscler particle of certain length automatically in this process.Particle is mixed by a certain percentage with the Imitation Rock Porcelain Tiles powder that is different from grain color, repressed, dry, burn till, deburring, polishing, can be made into the polished bricks that there is microscler particle on the surface.Powder and strip shaped grain all can add suitable colorant and make various needs colors.
The output of particle can be by improving the method control of the speed of mainshaft in certain limit; guaranteeing that plastic pug adds under the prerequisite of speed; improve the speed of mainshaft; can promote pug fltting speed in machine, and then improve the formation speed of mud bar, therefore increase particle output; also want corresponding raising belt conveyor rotating speed simultaneously; increase protection micro mist addition, otherwise can make the mud bar adhered to one another, destroy particle and form.
Further improve output if desired, can improve in design, increase main shaft 8 quantity.In the horizontal direction, main shaft can increase to 2,3,4 etc. by 1, and the hole on the iron plate just can increase much like this, and this way improves output and gets instant result more.Schematic diagram 2 be exactly main shaft be that 1 and main shaft increase to 3 situation contrast.Certainly we will guarantee that motive force is enough, otherwise pug can't be extruded from the hole, causes equipment stuck.
Production craft step of the present invention is as follows:
1) preparation of plastic mud cake: mud, sand, stone, colorant, water are by Imitation Rock Porcelain Tiles proportioning (or low temperature material proportioning) weighing, and ball milling becomes mud, and through deironing, the back pressure of sieving considers into mud cake, mud cake moisture content percentage by weight can be controlled in 18-25;
2) preparation of mud bar: mud cake is extruded along the hole (bore dia is less than 10mm) of certain diameter under pressure, the mud bar of extruding drops on the belt, for preventing that it from boning mutually, at the unrestrained simultaneously a certain amount of micro mist of mud bar outlet, the mud bar and the micro mist mixture that form are delivered in the pallet by belt, and the mud bar has produced certain fracture in this process;
3) the mud bar is carried and is dry: under the carrying of pallet, and micro mist and mud bar mixture drying, control mud bar moisture content percentage by weight 6-12;
4) acquisition of ceramic polished tile strip shaped grain: micro mist after the drying and mud bar mixture are crossed 20 mesh sieves, sieve is micro mist down, in this process, the mud bar is fracture further, difference according to plastic clay drying intensity, breaking degree can be different, but after the plasticine bar fracture that general Imitation Rock Porcelain Tiles is formed, its size mainly concentrates on 2-30mm;
5) storage: through said process, the gained strip shaped grain will prevent its fracture in storing process, unless think that the gained particle is oversize.If prevent its fracture, can preserve the micro mist and the mixture of mud bar that after super-dry moisture content is fit to, when being about to use, sieve.Also can with polished brick in porcelain character base substrate powder and microscler particle mix the back and store;
6) use: with powder punch forming behind cloth of press or secondary material distributing of above-mentioned mixing, 40-300 ℃ of drying oozed flower and decorated, and 1150-1250 ℃ is burnt till, and after polishing, the deburring, can get surperficial polished brick in porcelain character with rectangular particle decorative effect.
The present invention prepares the strip shaped grain that is fit to the Imitation Rock Porcelain Tiles dry pressing first through experimental study.Strip shaped grain is cooperatively interacting with the bad body powder of Imitation Rock Porcelain Tiles of suitable color aspect material and the color, has the decorative effect of coordinating very much, for the consumer provides a kind of more natural polished brick in porcelain character, and imitation lithotome more true to nature.
Schematic diagram 1 is represented equipment work granulation process.
Schematic diagram 2 represents one to extrude what contrast of granulation hole when extruding with three.
Below in conjunction with equipment work schematic view illustrating prilling process (schematic diagram 1):
1 vacuum deairing machine: need less or during the test particle, can adopt single shaft to extrude, in certain limit, the available Frequency Converter Control speed of mainshaft Way regulate particle output, increase the speed of mainshaft and can improve particle output. Since sheet iron size limited (schematic diagram 2), the hole count of preparation mud bar Measure limitedly, output is therefore limited. When further when need improving output, can square upwards increase main shaft quantity (schematic diagram 2) at water.
2 plastic pugs: press filtration gained mud cake is added pug mill, and pug advances under screw rod promotes, and pug can be the Imitation Rock Porcelain Tiles material, according to Ceramic tile effect requirements difference also can be transparent material material.
4 mud bars: pug is extruded from the hole under pressure, forms the mud bar, mud bar random distortion, random fracture.
3 micro mists: the mud bar has certain viscosity, mutually bonds for preventing it, with the micro mist protection, is full of micro mist between the mud bar, as a result mud bar and mud specially Bar loses touch opportunity, and keeps separate. Micro mist can adopt the Imitation Rock Porcelain Tiles material, also can adopt low temperature material material, according to the particle effect not With, micro mist can be shades of colour, such as red micro mist, can be attached to final strip shaped grain edge and form red lines. Micro mist can be done with spraying The powder of dry tower preparation forms through the flour mill polishing.
6 belts: carry mud bar and micro mist, change it over to pallet, mud bar meeting random fracture in course of conveying, the mixture of formation mud bar and micro mist 5 (schematic diagrames 1).
7 pallets: the container of splendid attire mud bar and micro mist mixture, 5 (schematic diagrames 1) carry out drying under this loads.
Through behind the moisture control, with the mixture screening, can obtain the strip shaped grain for the Imitation Rock Porcelain Tiles moulding.
