[0030] Fig. 3 is a schematic structural view of the first embodiment of the present invention, in which the gratings are arranged in a set spacing manner with sparse middle and denser sides in the kiln channel. As shown in Figure 3, a bracket 3 is provided on the kiln body 1 of this embodiment, a guide groove 31 is provided on the bracket 3, a guide hole 22 is opened on the grid bar 21, and the bolt passes through the guide hole 22 and the guide groove 31 to connect the grid The bars 21 are connected to the support 3, and the distance between the grid bars 21 can be adjusted due to the guide grooves 31, so that the grid bars 21 are suspended in the kiln channel 10 in a manner that is sparse in the middle and dense on both sides. In the upper part, by concentrating the airflow in the kiln passage to the middle area, the purpose of increasing the middle temperature is achieved, and the temperature of the cross-section of the kiln passage is evenly distributed when the middle temp...

[0037] Fig. 5 is a schematic structural view of the third embodiment of the present invention, in which the grid bars are arranged in the way of setting the extension length in the middle of the kiln passage and lower on both sides. As shown in Figure 5, the kiln main body 1 of this 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, due to the guide The holes 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 in a manner that the middle is high and both sides are low. The internal air flow is concentrated to the middle area to achieve the purpose of increasing the middle temperature, so that the cross-section temperature of the kiln channel is 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...
