Description

A kind of pottery burns till roller kilns

[technical field]

The utility model relates to a kind of ceramic wall and floor bricks and burns till roller kilns, relates in particular to a kind of wide section face calcinated ceramic-trick roller-bed kiln.

[background technology]

Because the restriction of composite factors such as roller kilns self structure, burner combustion technology, various fuel different qualities, big more its section temperature difference of roller kilns inner width is big more, thereby and the bigger section temperature difference can cause roller kilns to burn till product aberration and difference in size occurring and reduce product quality.Knowhow shows for many years, and burning till the roller kilns inner width, to surpass 2.6 meters its section temperature difference bigger to the quality influence of product, particularly produces very obvious at the big Imitation Rock Porcelain Tiles of shrinkage factor.In order to eliminate the roller kilns cross section temperature difference, though the general employing of prior art adds fireguard and can reduce the cross section temperature difference, but because fireguard is a complete ceramic beaverboard, the flue gas circulating resistance is strengthened, need to be equipped with the high smoke exhaust fan of pressure, not only increase power consumption, and in the poor effect of the longer kiln passage inner control temperature difference.Another kind method is that clinkering zone is established the part temperature-adjusting burner, improves the temperature of both sides in the kiln body cross section, controls but temperature-adjusting burner and common burner overlap temperature control system with one, is difficult to be transferred to optimum state.All there is big limitation in these two kinds of methods, thereby can not realize adjusting flexibly the even distribution of flue gas stream on the roller kilns cross section can't realize burning till roller kilns cross section temperature evenly, burn till roller kilns and develop the production that makes whole ceramic industry to wideer direction and enter bottle directly with regard to having limited like this.

Adopt wide roller kiln to realize that the technology purpose of burning till workshop section has very high economic worth for Production of Ceramics producer, take the roller kilns of 2.5 meters of the roller kilns of 3 meters of inner widths and inner widths to come comparison, the burning till roller kilns the former can improve 1/3rd output than the latter of equal length.Before 2002, it is that 3 meters Imitation Rock Porcelain Tiles is burnt till roller kilns that some enterprises attempt adopting above-mentioned solutions commonly used to invest to build inner width, all because of not eliminating the cross section temperature difference effectively test manufacture the time is counted out, nobody dares to make inquiries the Imitation Rock Porcelain Tiles of inner width more than 3 meters or 3 meters and burns till roller kilns more afterwards.We can say that how effectively the roller kilns cross section temperature difference is burnt till in elimination has become the key factor that the Imitation Rock Porcelain Tiles firing field improves the quality of products, boosts productivity.

[utility model content]

The utility model provides a kind of to have common burner and the independent control system of temperature-adjusting burner regional temperature, thereby realization cross section temperature is burnt till roller kilns uniformly.

The utility model adopts following technical scheme for achieving the above object:

A kind of pottery burns till roller kilns, include the kiln body, be provided with passage in kiln body inside, in passage, be provided with several clubs that are arranged in a row, on the kiln body, be provided with according to passage two side areas detected temperatures and design temperature the passage two side areas is carried out several sidepiece temperature adjustment combustion systems of temperature adjustment heating and according to passage zone line detected temperatures and design temperature the passage zone line carried out several middle part temperature adjustment combustion systems that temperature adjustment is heated.By being used of two class autonomous systems, will make the middle part of whole kiln body inside reach consistent like this, thereby eliminate the kiln body passage section both sides and the middle temperature difference with the temperature of both sides.

The beneficial effects of the utility model are: because the temperature of kiln body passage section central region and passage lateral region respectively adopts independent temperature control system to control, so each regional adjustment flexibly, accurately on the kiln body passage section, reach kiln body passage section samming easily, the product that makes kiln body passage inner width produce different qualities at the expanded letter roller-way more than 3 meters becomes possibility.The utility model is simple in structure, and is easy to operate.
