Problems solved by technology

[0005] The purpose of the present invention is to provide a method for adjusting the flue gas flow at the cross-section of the roller kiln by adjusting the temperature uniform grid bar group to solve the technical defects that the existing technology cannot effectively eliminate the temperature difference of the cross-section of the roller kiln and the inner width of the roller kiln cannot exceed 2.6 meters. The fired porcelain brick roller kiln distributed on the surface has the characteristics of controlling the temperature difference without being limited by the width, and the flue gas flow resistance is small, making it possible for the fired porcelain brick roller kiln to have a width greater than 2.6 meters

[0034] Figure 5 It is a structural schematic diagram of the third embodiment of the present invention, in which the grid bars are arranged in the way that the middle is high and the two sides are low, and the preset length of extension is arranged in the kiln channel. Such as Figure 5 As shown, the kiln main body 1 of the present embodiment is provided with a bracket 3, and several guide holes 22 are provided on the grid bar 21, and the bolt passes through one of the guide holes 22 to connect the grid bar 21 to the bracket 3, because the guide hole 22 can Adjust the length of each grid bar 21 extending into the kiln channel, so that the grid bar 21 is suspended on the upper part of the kiln channel 10 in the kiln channel 10 with a high middle and low sides. The middle area is concentrated to achieve the purpose of increasing the middle temperature, so that the cross-section temperature of the kiln channel can be evenly distributed when the middle temperature is low.

Abstract

This invention relates to a roller stove for baking porcelain bricks including a main part of a stove forming a stove channel set with a grid-strip set at uniform temperature for altering gas flow direction in the channel to drive the temperature of the cross section to distribute uniformly and having several grid strips arrayed in a designed way and set at the upper part of the channel, the designed way includes a designed gap mode, an extended length mode and a combined mode of the two, which alters the gas flow direction of various regions in the channel by the gaps among the grid strips or regulation of high and low positions to change the distribution of the gas flow of high and low temperature in the cross section of the stove to eliminate the difference in temperature of roller stoves.

Description

technical field [0001] The invention relates to a roller kiln for firing wall and floor tiles, in particular to a roller kiln for firing porcelain tiles which can effectively eliminate the temperature difference in the cross section. Background technique [0002] Due to the structural constraints of the roller kiln, the larger the inner width of the roller kiln, the greater the temperature difference across the cross section, and the larger cross section temperature difference will lead to color and size differences in porcelain tiles, which will lower the product grade. Years of production experience have shown that the inner width of the fired porcelain tile roller kiln should not exceed 2.6 meters, otherwise the product quality will be unstable. In order to eliminate the temperature difference in the cross-section of the roller kiln, the existing technology generally adopts methods such as adding a fire baffle and adding a temperature-adjusting burner. The distribution o...
