Energy-saving glazing roller kiln for producing interior wall bricks

Abstract

The invention provides an energy-saving glazing roller kiln for producing interior wall bricks. The kiln top of the roller kiln is built by using a suspended wool board structure. The kiln bottom of a firing region consists of low-iron and high-aluminum heat reserving bricks, high-aluminum poly-light ball heat reserving bricks and light clay bricks, wherein the light clay bricks are positioned in a bottom layer at the kiln bottom of the firing region; the high-aluminum poly-light ball heat reserving bricks and the low-iron and high-aluminum heat reserving bricks are built in turn above the light clay bricks; a fume extractor is arranged in the built kiln and positioned above a smoke exhaust region of the roller kiln and comprises a top exhaust tube and a main exhaust tube; and one end of the top exhaust tube and one end of a side exhaust tube are connected to the smoke exhaust region of the roller kiln, while the other ends are connected with the main exhaust tube. In the fume extractor, top extraction and side extraction are combined, so that air stream uniformly flows towards a direction opposite to the running direction of unburned bricks, brick bodies are heated stably and glaze cracks possibly caused by non-uniform heating are avoided.

Description

Technical field: [0001] The invention relates to the technical field of kilns, in particular to an energy-saving glaze-fired roller kiln for producing interior wall bricks. Background technique: [0002] With the continuous development of the ceramic industry and the increasingly fierce competition, only by increasing production, reducing energy consumption and improving product quality can we occupy a favorable position in this highly competitive environment. However, the traditional inner wall brick glazed roller kiln has a relatively simple kiln body structure, and the kiln roof adopts a ceiling structure of insulating bricks, which is heavy and is easy to get dirty on the brick surface in the kiln, resulting in glaze defects and damage to the kiln body. The width is narrow, the number of batch firings is small, the output is difficult to increase significantly, and the relative energy consumption is relatively large. How to increase output, reduce energy consumption, and...

However, the traditional inner wall brick glazed roller kiln has a relatively simple kiln body structure, and the kiln roof adopts a ceiling structure of insulating bricks, which is heavy and is easy to get dirty on the brick surface in the kiln, resulting in glaze defects and damage to the kiln body. The width is narrow, the number of batch firings is small, the output is difficult to increase significantly, and the relative energy consumption is relatively large. How to increase output, reduce energy consumption, and improve the quality of glazed tiles is the primary research topic for current ceramic manufacturers.
