Abstract
A wide section surface double-deck packed sanitary ware tunnel kiln comprises a smoke discharging section, a preheating section, a firing section, a quenching, indirect cooling, rapid cooling section and the like. Double-deck packed of the sanitary ware can be achieved in process of firing. Containing height of the double-deck packed sanitary ware tunnel kiln is 1.5-2 times as high as the single-deck packed sanitary ware tunnel kiln. Compared with the single-deck packed sanitary ware tunnel kiln, burners are arranged on the bottom portion of kiln walls of the two sides of the preheating section in a crossed mode. Air curtain blast pipes are arranged in the same position with the burners on the upper portion of the kiln walls facing to the two sides, provided with the burners, of the preheating. The air curtain blast pipes are connected with the draught fans. High pressure gas is blown into the kiln and forms a stirring system with hot flue blown from burners, and therefore differences in temperature of the upper side and the lower side of the section of the kiln are reduced effectively. An upper row of burners and a lower line of burners are arranged in the firing section. The burners are divided into an upper group and a lower group and each group is controlled independently. Each group corresponds to a thermocouple. Indirect cooling walls and air bellows are arranged at the top of the indirect cooling section and the upper portion of the two sides of the kiln wall. Difference in temperature of the kiln section can be controlled by adjusting of opening degree of each air bellow.
Description
Technical field
The utility model relates to a kind of kiln of ceramic product, particularly a kind of cleaners and polishes tunnel cave.
Background technology
Domestic existing cleaners and polishes tunnel cave exists energy consumption high, the little series of problems that waits of output.When output is large, the floor space of kiln again more greatly, longer, this just makes the operation of manufacturer high, investment is large.My company is according to design and the commissioning experience of two more than ten years, burns till principle according to sintering curve and the pottery of cleaners and polishes, and development and design has gone out wide section double-layer tunnel kiln, and in the operation of going into operation of Guangdong sanitary equipment factory.Its energy-saving effect is obvious, and energy consumption of unit product drops to every kilogram of porcelain of 1050cal by original 1200cal.In the situation that floor space is identical, improved output, realized more large economy effect.Cleaners and polishes are because volume is large, fills highly, and upper and lower temperature difference is very difficult to be controlled, and when excessive temperature differentials, just increases the percent defective of sanitary equipment.
Summary of the invention
For the problems referred to above, the utility model provides the double-deck code dress of a kind of wide section cleaners and polishes tunnel cave, adopt the firing mode of Double layer loading, the dress height is 1.5-2 times of traditional kiln, on Yao Qiang top, preheating zone air curtain wind is set, side wall bottom, opposite arranges burner, has stirred like this thermal current, has effectively reduced the temperature difference.Clinkering zone has adopted and has burnt till more accurately control mode and scheme, and the two rows burner divides up and down 2 groups of independent controls, separately controls to adjust gas quantity and the combustion air volume of every group of burner with thermocouple, make the temperature difference can be controlled at ± 2 degree in.
Concrete technical scheme of the present utility model is:
The double-deck code dress of wide section cleaners and polishes tunnel cave, comprise smoke evacuation section, preheating section, the section of burning till and quench zone, cold section, cold section soon, can burn till by double-deck code dress cleaners and polishes, it is characterized in that: cleaners and polishes can fill by double-deck code, every layer can fill two cleaners and polishes by code at least, the preheating section kiln wall bottom burner that is crisscross arranged, offside Yao Qiang top co-located arranges the air curtain airduct, and the air curtain airduct links to each other with blower fan; The section of burning till arranges the two rows burner, the independent control of two row's groupings, every group of corresponding 1 thermocouple; Between cold wall and bellows between cold section setting.
Described air curtain airduct is corresponding with other side kiln wall burner, and is in the kiln length direction same plane.
The section of burning till is provided with the two rows burner, minute up and down two groups of independent controls, and every group of corresponding thermocouple separately controls to adjust gas quantity and the combustion air volume of burner.
Between cold section on Yao Qiang top, both sides simple cold wall is set, the top is arranged side by side a plurality of bellows, separate regulation.
By adopting technique scheme, because hot-air density is little, out hot-air total distributed is on the top in kiln cross section in the kiln wall Bottom Nozzle Used, on kiln top air curtain wind is set, directly be blown into the air of high pressure, hot-air is moved downward, form and stir, can dwindle the upper and lower temperature difference in kiln cross section.Cold section product defects easily occurs between wide section kiln, and we arrange bellows and accurate control program on the kiln top, efficiently solve cold section problem that the infantile convulsion defective easily occurs between wide section face kiln.
Certainly, energy-conservation is that national policy is encouraged direction, and kiln can also to longer future development, improve the absolute power consumption values of product.
Description of drawings
Fig. 1 is the utility model tunnel cave preheating section profile;
Fig. 2 is cold section profile between the utility model tunnel cave.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
As illustrated in fig. 1 and 2, double-deck code dress cleaners and polishes tunnel cave of the present utility model, comprise smoke evacuation section, preheating section, the section of burning till and quench zone, cold section, cold section soon, can fill cleaners and polishes by double-deck code in its kiln, every layer can be filled to few two cleaners and polishes by code, preheating section sidewall bottom arranges burner 1, and wall top co-located is arranged air curtain airduct 2, and the air curtain airduct links to each other with blower fan; The section of burning till arranges up and down two groups of burners; Between cold wall 3 and bellows 4 between cold section setting.
Described air curtain airduct 2 is corresponding with the burner of offside kiln wall, and is in the kiln length direction same plane.
The section of burning till two rows burner divides up and down two groups of independent controls, and every group of corresponding 1 thermocouple separately controls to adjust gas quantity and the combustion air volume of burner.
As shown in Figure 2, cold section cold wall 3 between Yao Qiang top, both sides of letter, the kiln top is arranged side by side a plurality of bellows 4, separate regulation.
