The utility model is described in further detail with reference to the accompanying drawing.
With reference to shown in Fig. 1, Fig. 2, Fig. 3, the utility model discloses a kind of roller kilns for roasting handmade finish brick, along product Traffic direction, respectively by smoke evacuation preheating zone 102, oxygenolysis band 103(be burnt into leading portion), high temperature firing band 104, chilling band 105, slow cooling and tail cold belt 106 etc. form.The kiln body 101 of the roller kilns, which is equipped with, to be run through between kiln hood and kiln tail for holding It carries and the roller stick 115 of conveying decorative brick, the roller stick 115 passed through in kiln road constitutes service aisle bottom surface.The work of the roller kilns As system include be made of smoke-exhaust pipeline 114, chilling air pipe line 109, waste heat air draft pipeline 110 and tail cold wind pipeline 111 it is logical Wind system, the combustion system being made of fuel gas pipeline 107 and combustion-supporting air pipe line 108.The chilling band 105 relatively routine has added It is long, guarantee cooling sufficiently, product kiln discharge temperature is low.
The firing period of the roller kilns is 5-7 hours, and the temperature range for preheating zone 102 of discharging fume is high at 350~400 DEG C The temperature range of warm clinkering zone 104 is at 1100~1250 DEG C, and the temperature range of oxygenolysis band 103 is at 800~950 DEG C.
Advanced optimized as to above embodiment, the smoke evacuation preheating zone 102 by smoke evacuation preheating kiln frame 201, Smoke evacuation preheating kiln bottom 202, smoke evacuation preheating kiln wall 203 and smoke evacuation preheating kiln top 204 form, and are equipped with smokejack 207 and lower row on side Flue 208, can anti-falling stop it is dirty.The smoke evacuation preheating kiln wall 203 is divided into kiln wall up and down by seamless steel pipe roller stick 205, seamless It is provided with high alumina ceramic supporting plate 206 on steel pipe roller stick 205, accident treatment mouth 213 is equipped on Xia Yaoqiang.The smoke evacuation preheating kiln Top 204 is made of cordierite I-shaped brick 209, cordierite refractory plate 210, alumina silicate fibre blanket 211 and rock wool 212 from the inside to the outside. The surface of the cordierite I-shaped brick 209 and cordierite refractory plate 210 is more smooth, not easy to hang dirty, is also not easy to fall dirty.The smoke evacuation Difference in height at the top of 204 bottom of preheating kiln top and decorative brick is controlled in 130mm or more.
Advanced optimized as to above embodiment, the high temperature firing band 104 by high temperature firing kiln frame 301, High temperature firing kiln bottom 302, high temperature firing kiln wall 303 and high temperature firing kiln top 304 form.The high temperature firing kiln wall 303 is by height Aluminium ceramic rod 305 is divided into kiln wall up and down, on high alumina ceramic roller stick 305 on be provided with high alumina ceramic supporting plate 306, on upper kiln wall Equipped with top burner 307 and peephole 309, lower kiln wall is equipped with sinking burner 308 and accident treatment mouth 213.The high temperature is burnt It is made of at kiln top 304 high alumina suspended roof brick 310 and alumina silicate fibre blanket 211, the high alumina suspended roof brick 310 is held by suspension hook 312 It is hung on furred ceiling beam 313, it is extremely convenient to build installation.
As the optimization to above embodiment, the decorative brick being burned is piled up by 5 layers, greatlys improve the production of product Efficiency.Roller stick 115 is relatively large in diameter, and specification is 55 × 2500mm of Φ, and empirically formula calculates capping value and slightly biased big for roll spacing 80mm is easy to pass through convenient for heat.Supporting plate is housed, specification is the mullite plate of 500 × 370 × 14.5mm, is guaranteed on roller stick 115 After roller kilns operate for a long time, impurity can be deposited on supporting plate rather than directly in roller surfaces, anti-major structure in glaze and flue gas At 115 surface irregularity of roller stick, to influence normal operation of the product on roller-way.
It is advanced optimized as to above embodiment, the inner space Yao Dao of the roller kilns is higher than conventional roller kilns About 67mm, product top are controlled with kiln top/bottom part height in 130mm or more, so that air-flow is unimpeded and the volatilization of color glaze.
It is advanced optimized as to above embodiment, oxygenolysis band 103 is to be burnt into the temperature of leading portion higher than conventional Roller kilns, while the air input of burner is tuned up, and two section mistakes are equipped between smoke evacuation preheating zone 102 and oxygenolysis band 103 Area is crossed, guarantees that the oxidative decomposition of the thick glaze of product surface is abundant, and keeps reaction gas in green body complete before glaze melting Full discharge, avoids generating glaze paint in dysoxidation and lacking for the glaze paints out-of-flatness such as stomata or pin hole occurs in " eggshell " shape, glaze paint It falls into.
The utility model is that handmade finish brick is rapidly fired to roller kilns, belongs to continous way kiln, high-grade manual for producing Decorative brick has thicker glaze layer on the green body of product, for the output for improving single kiln, is piled up using multilayer, a variety of by taking Comprehensive technical measure, guarantee super large mass production methods under product quality in the quality under the production model of small lot not phase Under.Single kiln firing period of the roller kilns is only 5~7 hours, and high degree of automation, production cost is low, be may be implemented extensive Production.The roller stick diameter of roller kilns is big, and gap is larger, and heat is easy to pass through.It is covered with that it can be used repeatedly on roller stick simultaneously again easily In displaced supporting plate, impurity can be only deposited on supporting plate rather than directly in roller after roller kilns operate for a long time in glaze and flue gas Sublist face prevents from causing roller stick surface irregularity.The inner space Yao Dao about 67mm higher than conventional roller kilns, product top and kiln top Bottom level control is in 130mm or more, and to be conducive to, air-flow is unimpeded and the volatilization of color glaze.The temperature for being burnt into leading portion is higher than conventional roll Road kiln, siding-to-siding block length is big, and the product residence time is long, and the oxidative decomposition of glaze is abundant, and makes in green body reaction gas in glaze It is completely exhausted out before melting, avoids the occurrence of glaze quality defect.The lengthening of quench zone ensure that firing product are quickly fully cooled, and produce Product kiln discharge temperature is low.Firing temperature is uniform in kiln road, and product is indeformable, and sintering degree consistency is good, using the utility model skill The handmade finish brick that art carries out mass production equally has strong artistic infection effect.
In addition, the utility model is not limited to the above embodiment, as long as it reaches originally practical with essentially identical means Novel technical effect, all should belong to the protection scope of the utility model.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and the embodiment that part uses, For those of ordinary skill in the art, without departing from the concept of the present invention, if can also make Dry modification and improvement, these are all within the protection scope of the present invention.
