Multi-spark-plug fuel gas jun porcelain kiln

Abstract

The invention discloses a multi-spark-plug fuel gas jun porcelain kiln which comprises a kiln body, wherein the kiln body comprises an outer kiln body and an inner kiln body; each of the outer kiln body and the inner kiln body is of a cuboid structure; the inner kiln body is a hollow structure built from refractory bricks; an interlayer space for mounting a spark plug component is formed between the inner kiln body and the outer kiln body; the spark plug components are arranged on the obverse side and the two sides of the inner kiln body; a smoke discharging pipeline stretches out of the backside face of the interlayer space from inside to outside and communicates with an external chimney; the chimney is mounted above the smoke discharging pipeline in a sleeving manner; an inverted funnelshaped structure is arranged at the lower part connecting end of the chimney; and the spark plug components are connected with a fuel air inlet system. Through improving the structure of the multi-spark-plug fuel gas jun porcelain kiln, arrangement of the spark plug is more reasonable; and in addition, the chimney structure is improved, so that the multi-spark-plug fuel gas jun porcelain kiln isfilled with flames to form a reducing atmosphere with negative pressure, and the yield and the appearance artistry of ceramics fired by the multi-spark-plug fuel gas jun porcelain kiln can be improved.

Description

technical field [0001] The invention belongs to the technical field of porcelain firing equipment, and in particular relates to a multi-burner gas Jun porcelain kiln. Background technique [0002] In the Song Dynasty, Jun porcelain began to be fired with firewood, and in the Jin and Yuan dynasties, coal-fired began to appear. At the end of the Yuan Dynasty, because the shallow coal was exhausted and the deep coal was not easy to dig, firewood was used again. Liquefied petroleum gas has successfully fired Jun porcelain. This technology has obvious advantages in preventing air pollution, reducing labor intensity, and changing the space of Jun porcelain works. [0003] Technically speaking, coal-fired Jun porcelain requires the most labor. Commodity needs to be filled with saggers, coal quality needs to be strictly controlled, and the firing tank needs to be sorted out. Every time the kiln is ignited, it is necessary to install the kiln, spread the fire, and block the kiln doo...

Problems solved by technology

[0004] However, there are still some improvements in the existing liquefied gas firing methods. On the one hand, based on the structural limitations of the Jun porcelain kiln, the position of the burner is not reasonable enough, and the yield is low. On the other hand, Yes, due to the unreasonable setting of the smoke exhaust structure of Jun porcelain, the reducing atmosphere in the kiln is not easy to form, which affects the effect of the glaze color of Jun porcelain. In addition, in the existing firing method, the waste heat of the kiln is directly discharged into the furnace through the flue. In the atmosphere, it not only causes waste of heat, but also requires additional heating of the combustion material. Since a certain amount of dust is carried in the flue gas, it will cause certain pollution to the atmosphere.
