Description

Technical Field

[0001] The utility model belongs to the technical field of industrial kilns, and particularly relates to an industrial kiln with a uniform heating structure. Background Art

[0002] The shortcomings of existing industrial kilns in terms of uniform heating are mainly reflected in uneven temperature distribution, high energy consumption and unstable product quality. First, uneven temperature distribution will lead to significant temperature differences in different areas of the kiln, thereby affecting the uniformity of the heating process, resulting in uneven heating of the product during the heating process, and ultimately affecting product quality, such as deformation, cracks or insufficient strength. Secondly, due to uneven heating, higher energy consumption is required to achieve the ideal heating effect to compensate for the impact of uneven temperature distribution, which not only increases production costs, but also puts higher requirements on energy utilization efficiency. Thirdly, uneven heating will lead to unstable product quality, reduced product qualification rate, and affect the overall efficiency and output of the production line. These shortcomings are mainly due to the limitations of existing kiln design and control systems. The kiln structure is complex, and the internal airflow and heat conduction paths are diverse, which makes it difficult to control the heat distribution and leads to uneven temperature distribution. At the same time, the inadequacy of kiln materials and thermal insulation performance will also aggravate this problem, resulting in large heat loss and low heating efficiency. Conventional countermeasures include optimizing the kiln structure design and improving the performance of thermal insulation materials. Optimizing the kiln structure design can improve airflow and heat conduction paths, making heat distribution more even; improving the performance of insulation materials can reduce heat loss and improve heating efficiency.

[0003] However, these coping methods also have certain drawbacks. Optimizing the kiln structure and improving the performance of insulation materials require a lot of R&D investment and technical support, which increases the initial cost and technical difficulty. In addition, these improvement measures usually need to be modified on the basis of the existing production line, which may lead to production stagnation and instability during the transition period. Therefore, we hope to design an industrial kiln with a new structure to solve this problem. Utility Model Content
