Description

Technical Field

[0001] This utility model relates to the field of kiln technology, specifically to a high-efficiency and energy-saving kiln for firing ceramic handicrafts. Background Technology

[0002] A kiln is a furnace used for firing ceramics and sculptures, or for fusing enamel onto the surface of metal objects. It is generally constructed of brick and stone and can be made in various sizes to meet specific needs. It can be powered by combustible gas, oil, or electricity. Electric kilns are easier to control in terms of temperature than those using combustible gas or oil, but some potters and sculptors believe that the temperature rises too quickly in electric kilns. The temperature inside the kiln is measured using a pyrometer or thermometer cone and can be observed through a peephole.

[0003] A kiln is a piece of equipment made of refractory materials used to fire ceramic products; it is an essential facility in the process of pottery making. Over tens of thousands of years of ceramic firing history, humankind has accumulated a wealth of kiln styles and experience. From open-air firing and pit firing in primitive societies to dome-shaped rising-flame round kilns, semi-downdraft horseshoe-shaped kilns, semi-slope dragon kilns, and egg-shaped kilns, and then to modern indoor gas kilns and electric kilns, kiln technology has continuously improved and developed.

[0004] Currently, after ceramic crafts are formed, they need to be fired in a kiln to form hard and smooth ceramics. However, existing ceramic craft firing kilns are not very efficient and energy-saving because the ceramic crafts are not heated sufficiently and the fuel is not fully burned. Utility Model Content
