Ancient architecture repairing grey tile firing process and system

Abstract

The invention discloses an ancient architecture repairing grey tile firing system which consists of a water gas generation furnace, a gas storage tank and a gray tile firing assembly line, wherein thewater gas generation furnace is used for producing a water gas; and the gray tile firing assembly line comprises a vacuum extrusion molding machine, a gray tile moving roller way, a high-temperatureroller way kiln and a distillation cooler. The invention further discloses an ancient architecture repairing grey tile firing process. A gray tile is prepared from the following raw materials in percentage by weight: 25-35% of building wastes, 35-45% of clay and 30% of coal gangue. By adopting the ancient architecture repairing grey tile firing system disclosed by the invention, distilled water generated from vapor is adopted as a cooling medium, the purity of the distilled water is greatly greater than that of common industrial tap water, and the distilled water has a very low internal oxygencontent and is free of other impurities inside, so that no other chemical reaction is caused when the distilled water contacts a tile body in the cooling process of the gray tile, the structural permeation resistance of a finished product of the gray tile can be improved, the color of the gray tile can be changed naturally, no other pigment is used, meanwhile, the cooling contact area of a gas iswide, and the cooling efficiency can be improved.

Description

Technical field [0001] The invention relates to the technical field of ancient building restoration, in particular to an ancient building restoration blue tile firing process and system. Background technique [0002] Blue tiles generally refer to clay blue tiles. It is made of clay (including powders such as shale and coal gangue) as the main raw material and is made by mud treatment, molding, drying and roasting. The color is not cyan, but dark blue and gray blue. [0003] China's blue tiles were produced earlier than bricks, and they are mainly used for roofing, roof ridges, and tiles. Blue tiles give people a sense of elegance, calmness, simplicity, and tranquility. They are often used in contemporary antique buildings. Traditional blue tile firing kilns are mostly wheel kilns or thick-wall tunnel kilns. Wheel kilns or thick-wall tunnel kilns are generally made of construction clay bricks or cement bricks, which cover a large area and are filled with tiles. Out of the kiln co...

AI Technical Summary

Problems solved by technology

The firing kilns of traditional blue tiles are mostly wheel kilns or thick-wall tunnel kilns, which are generally made of building clay bricks or cement bricks, occupying a large area and the input of tile embryos. It takes a lot of manpower and time to get out of the kiln, and the firing time is long, which is not conducive to the production of blue tiles in batches

At the same time, the current blue tile cooling on the market uses tap water as a cold source. Impurities in tap water are easy to react chemically with the raw materials in the heated tile billet, resulting in low service life of tiles. At the same time, it is difficult to achieve uniform cooling with tap water.
