Biscuiting roller kiln used for producing interior wall tiles

Abstract

The invention provides a biscuiting roller kiln used for producing interior wall tiles. The roller kiln comprises a smoke exhaust region, a firing region and a cooling region, wherein the smoke exhaust region and the cooling region of the roller kiln have hung ceiling structures formed by hanging high-aluminum poly light ball heat preservation bricks; a heat preservation buffer region is formed between a constructed vault and the hung ceiling by hanging the high-aluminum poly light ball heat preservation bricks; the surface layer of a kiln bottom is constructed by low-iron high-aluminum heat preservation bricks; the intermediate layer of the kiln bottom is constructed by the high-aluminum poly light ball heat preservation bricks; the bottom layer of the kiln bottom is constructed by light clay bricks; a smoke gas and afterheat composite using structure is arranged a constructed kiln; and the smoke gas and afterheat composite using structure supplies smoke gas generated in the kiln to the front part of a kiln-front drier and supplies afterheat to the back part of the kiln-front drier. The afterheat generated by the smoke exhaust region and the cooling region of the scheme is transported to the kiln-front drier by the smoke gas and afterheat composite using structure for drying green bricks without an additional drying heat source. After adopting the scheme, the biscuiting roller kiln has the characteristics of low energy consumption, high afterheat utilization efficiency, and remarkable economic benefit and social benefit.

Description

Technical field: [0001] The invention relates to the technical field of kilns, in particular to a bisque-fired roller kiln for producing interior wall bricks. Background technique: [0002] The traditional roller kiln for bisque firing of inner wall bricks has a relatively simple kiln body structure, and the kiln roof adopts a flat top structure, and the gas fluidity is poor; the width of the kiln body is mostly below 2900mm, and the output is difficult to increase significantly, and the relative energy consumption is relatively large. With the continuous development of the ceramic industry, the competition is becoming increasingly fierce. Only by increasing production and reducing energy consumption can we occupy a favorable position in this highly competitive environment. In order to achieve the purpose of increasing production and reducing energy consumption, it is necessary to start with the structure of the kiln body, rationally configure it, and make full use of the wa...
