Description

Technical Field

[0001] The utility model relates to the technical field of kilns, in particular to a kiln smoke exhaust inlet device. Background Art

[0002] A kiln is a device used to fire ceramics, glass, metal and other items. It is usually constructed of materials such as bricks, clay or metal, and has high temperature resistance and fire resistance. The kiln can provide a high temperature environment, so that the raw materials undergo high temperature heating, melting, crystallization and other processes in the furnace, thereby completing the production of items. There are many types of kilns, such as ceramic kilns, glass kilns, metal melting furnaces, etc. Different types of kilns are different in structure and working principle. Ceramic kilns generally adopt intermittent operation, and provide heat by controlling fuel combustion, so that ceramic products can complete sintering and glazing processes in the furnace. Glass kilns usually adopt continuous operation, and provide high temperature through resistance heating or combustion furnaces, so that glass raw materials can be melted and formed. Metal melting furnaces generally use arc heating or combustion furnaces to provide high temperature, so that metal raw materials can be melted into liquid metal. Kilns are widely used in industrial production, such as ceramic manufacturing, glass manufacturing, metal smelting and other industries. It can not only efficiently complete the production of items, but also control parameters such as heating temperature, time and atmosphere to meet the processing needs of different items.

[0003] In the prior art, in actual use, the tail end of the kiln's flue is located at the outermost side of the building, and the exhaust smoke is generally direct exhaust. In order to prevent the external environment from entering the flue, a protective cover is generally provided. The structure of this cover is relatively simple. Based on this problem, we propose a kiln smoke exhaust inlet device. Utility Model Content
