本文总结了1978～1983年以来长期使用的传统竖吹式气流再生机的不足,进行了新结构的研究,创制出了横吹式旧砂气流再生机新设备,该机于1983年6月由云南省科委组织全国性鉴定,经过现场测试并认真的评议,认为这项按重力加砂横吹原理,在我国首次研制成功的3吨/时横吹式旧矿气流再生机,设计具有自己的特点。它的出现,为中国型铸造车间旧砂再生开辟了一条新途径。现已由昆明市冶金机修厂生产,加以推广。
This article summarizes the shortcomings of the traditional vertical-flow air-flow regenerator which has been used for a long time since 1978 ~ 1983, studies the new structure and creates new equipment of horizontal-flow old sand air flow regenerator. The machine was constructed in June 1983 by Yunnan Provincial Science and Technology Commission organized a national appraisal, after field testing and careful comments, that this principle of gravitational plus sand horizontal blow, the first successful development in China, 3 tons / hour horizontal blasting old mine air flow regeneration machine, the design has its own characteristics. Its emergence has opened a new avenue for the regeneration of used sand in Chinese foundry. Now Kunming Metallurgical Machinery Plant production, to be promoted.
