Heat accumulating type high-temperature energy-saving kiln

Abstract

The invention relates to the technical field of kilns, and particularly discloses a heat accumulating type high-temperature energy-saving kiln. The heat accumulating type high-temperature energy-saving kiln comprises a kiln body, a smoke exhaust assembly and a combustion-supporting assembly and comprises a first heat accumulating burner unit and a second heat accumulating burner unit which work alternately. The heat accumulating type high-temperature energy-saving kiln is characterized in that the first heat accumulating burner unit and the second heat accumulating burner unit are each composed of multiple burners arranged in an up-down staggered manner, a gas connector is arranged at one end of each burner, a Y-shaped pipe is connected to the side wall of each burner, a main pipe of each Y-shaped pipe communicates with a combustion chamber in the corresponding burner, a first branch pipe and a second branch pipe of each Y-shaped pipe are connected with the smoke exhaust assembly and the combustion-supporting assembly correspondingly, a smoke exhaust valve is arranged on each first branch pipe, an air valve is arranged on each second branch pipe, and a first cold mixing pipe is further arranged between the combustion-supporting assembly and each burner in a communicating manner; and by additionally arranging the cold mixing structure, the interiors of the burners are cooled, so that the burners can adapt to the temperature higher than the original temperature.

Description

technical field [0001] The invention relates to the technical field of kilns, in particular to a regenerative high-temperature energy-saving kiln. Background technique [0002] A kiln is a device made of refractory materials for firing products, and is an essential facility in pottery molding. The tens of thousands of years of human ceramic firing history have accumulated rich kiln styles and experience. From the open-air pile firing on the ground in the primitive society, digging pits and building fires to steamed bun-shaped rising flame round kilns, half-down-flame horseshoe-shaped kilns, Banpo dragon kilns, and duck-egg-shaped kilns, to today's indoor gas kilns, electric kilns, and kiln technology In continuous improvement and development. [0003] During the working process of the kiln, the burner combustion chamber that continuously supplies heat needs to be in a high temperature state for a long time. When the temperature in the burner combustion chamber is too high,...

AI Technical Summary

Problems solved by technology

[0003] During the working process of the kiln, the burner combustion chamber that continuously supplies heat needs to be in a high temperature state for a long time. When the temperature in the burner combustion chamber is too high, it is easy to cause the burner combustion chamber to crack or even break, making the burner unable to adapt to higher temperature. The temperature of the kiln is low, resulting in a low comprehensive utilization rate of the kiln during the firing process of ceramic products, which cannot meet the needs of the production and development of the enterprise, the heat utilization rate is low, and the service life of the kiln is shortened.
