Abstract
The utility model relates to a reconstruction technology of an industrial kiln, in particular to a tunnel kiln special for a thermal insulation board. The tunnel kiln is provided with a kiln body, wherein the kiln body consists of a preheating section, a firing section and a cooling section, and is characterized in that the preheating section accounts for 17 percent of the total length of the kiln body; the firing section accounts for 10 percent of the total length of the kiln body; and the cooling section accounts for 73 percent of the total length of the kiln body. According to the tunnel kiln, the problems of high probability of cracking and extremely low product qualification rate of the thermal insulation board fired by the conventional tunnel kiln are solved; and the tunnel kiln is mainly used for firing the thermal insulation and fire-proof building material foamed ceramic board.
Description
The (1) technical field: the utility model relates to the renovation technique of Industrial Stoves, especially a kind of heat preservation plate material special tunnel kiln.
The (2) background technology: insulated fire building materials foamed ceramic plate is a kind of novel energy-conserving and environment-protective type material; This product proportion is 0.4, and thermal conductivity factor is very low, adopts existing kiln to fire; Product percent of pass is extremely low; The product that came out the same day is carefully, but to second day major part cracking has appearred, scrap.Proof can not be fired by the ceramic principle of routine after deliberation, and because of traditional kiln is divided into by curve: preheating section accounts for 36.5%, and the section of burning till accounts for 20%, and cooling section accounts for 43.5%.The problem that exists is that preheating section is long, too wastes kiln length; The section of burning till is long, and waste combustion gas and goods burn till the constant temperature time overlength, and are not energy-conservation; Cooling section is too short, and the goods internal temperature short time can't come out, though the surface cool off, so thereby the outer temperature difference greatly the shrinkage ratio gap is also big, cause due to self drawing crack.
The (3) summary of the invention: the purpose of the utility model is exactly will solve existing kiln can not adapt to the problem that insulated fire building materials foamed ceramic plate burns till, and a kind of heat preservation plate material special tunnel kiln is provided.
The concrete scheme of the utility model is: improve to the conventional panels tunnel cave, it has the kiln body, and the kiln body is made up of preheating section, the section of burning till, cooling section.It is characterized in that: wherein preheating section accounts for 17% of kiln body total length, and the section of burning till accounts for 10% of kiln body total length, and cooling section accounts for 73% of kiln body total length.
The principle of the utility model is: preheating section can be discharged moisture content and got final product; The section of burning till satisfies goods constant temperature till reaching the sintering degree; And cooling section need guarantee that goods relax cooling; Suitable expansion temperature 50～60 is spent can not to let product surface cooling maintenance too soon, and what heat was distributed in waiting for is synchronous.Therefore the utility model has shortened the preheating section and the section of burning till of kiln body according to the characteristic of heat preservation plate material, and cooling section has extended.
The utility model architecture advances is simple, has thoroughly solved insulated fire building materials foamed ceramic plate and has fired problem easy to crack, and product percent of pass because the section of burning till shortens, is saved the energy simultaneously up to more than 95%.
The (4) description of drawings
Fig. 1 is the surface structure sketch map of the utility model;
Among the figure, 1-preheating section, the 2-section of burning till, 3-cooling section.
The (5) specific embodiment:
Example 1: referring to Fig. 1, the utlity model has long 200 meters kiln body, wherein: preheating section 1 is designed to 34 meters, and the section of burning till 2 is designed to 20 meters, and cooling section 3 is designed to 146 meters.
Example 2: referring to Fig. 1, the utlity model has 300 meters kiln body, wherein: preheating section 1 is designed to 51 meters, and the section of burning till 2 is designed to 30 meters, and cooling section 3 is designed to 219 meters.
Claims (1)
1. a heat preservation plate material special tunnel kiln has the kiln body, and the kiln body is made up of preheating section, the section of burning till, cooling section, it is characterized in that: wherein preheating section accounts for 17% of kiln body total length, and the section of burning till accounts for 10% of kiln body total length, and cooling section accounts for 73% of kiln body total length.
