Energy-saving roller kiln for polished tiles

Abstract

The invention discloses an energy-saving roller kiln for polished tiles. Both the kiln crown and the kiln bottom of the roller kiln are built with mullite heat-preservation bricks, the built kiln crown is an arch crown and high-aluminum poly light sphere heat-preservation bricks and light clay bricks are laid under the kiln bottom in turn; holes are formed in the built kiln body for mounting a plurality of long spray gun silicon carbide sleeves and short spray gun silicon carbide sleeves alternately; and an encrypted gun is arranged in an oxidation zone in the kiln body by an encrypted gun silicon carbide sleeve. When the scheme is adopted, the uniformity of the temperature in the kiln in a section direction is improved, and the temperature difference is lowered and further controlled. After the green tiles are formed in a calcining zone, finished polished tiles at the temperature of below 60 DEG C are output from the exit of the kiln through a cooling area. The kiln adopting the scheme has simple structure, greatly improved heat preservation performance and greatly reduced energy consumption.

Description

Technical field: [0001] The invention relates to the technical field of kilns, in particular to an energy-saving roller kiln for polishing bricks. Background technique: [0002] The traditional polished brick roller kiln has a relatively simple kiln body structure and narrow kiln body width, which makes it difficult to greatly increase the output, and the relative energy consumption is relatively large. In order to increase the output, the kiln body is continuously lengthened, so it is difficult to increase the temperature in the front section, it is difficult to control the temperature in the oxidation section, and defects such as cracks are prone to occur. 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. In order to achieve the purpose of increasing production and...
