Technical Field
[0001] The utility model relates to the technical field of float glass cold end production, in particular to an edge cleaning cooling water vortex tube heat exchange device. Background Art
[0002] In the cold end production process of float glass, the edge cleaning cooling system is a key factor affecting the edge cleaning quality of the product. It is urgent to use new technologies to achieve rapid and accurate cooling, improve the edge cleaning quality, and meet market demand. In the cold end production process of float glass, edge cleaning (i.e. the processing process of the glass edge) is a key step to ensure the quality of the final product. In this process, the glass edge is cleaned and cut to ensure the overall appearance and dimensional accuracy of the product. Therefore, the effect of edge cleaning directly affects the quality and market competitiveness of glass products. In the cold end production process of float glass, the edge cleaning cooling system is an important factor affecting the edge cleaning quality. The main function of this system is to quickly reduce the temperature of the glass edge through cooling water so that it reaches the appropriate temporary stress for cutting and subsequent processing. However, the existing edge cleaning cooling water system has some limitations, especially in temperature control. The traditional edge cleaning cooling system is usually composed of an edge cleaning water system, which has deficiencies in temperature control and cannot flexibly adjust the water temperature according to production needs. Due to the inaccurate temperature control, it cannot effectively adapt to glass products of different thicknesses and specifications, resulting in poor cooling effect and may even affect the processing quality of the glass edge. Therefore, in order to meet the increasingly higher product quality requirements, traditional cooling methods can no longer achieve the needs of fast and precise cooling, which directly affects the edge cleaning quality and production efficiency of the product.
[0003] In view of this, a new edge cleaning cooling technology is urgently needed to provide faster and more accurate temperature control to meet the growing market demand and improve product competitiveness. To this end, the utility model provides an edge cleaning cooling water vortex tube heat exchange device. Utility Model Content
