倒U型还原蒸馏联合炉高温阀的优化改进

Improvement of High Temperature Valve for Inverted “U” Reduction-Distillation Connecting Furnace

高温阀是倒U型还原蒸馏联合法生产海绵钛的关键设备之一。原有的高温阀是由螺旋升降机构带动塞杆上下移动,达到关闭过道口,防止空气进入产品罐而污染海绵钛的目的。但存在劳动强度大、移动慢的缺点。对原有的高温阀结构做了优化改进,采用齿条-齿轮结构取代螺旋升降机构。生产实践证明,改进后的高温阀密封效果良好,操作人员由原来的3～4人降为1人,关闭时间由原来的10～15min降为2～3min,制作成本也由原来的7500元降至6000元。改进后的高温阀显著提高了工效,降低了劳动强度,已成为定型设备。

During the titanium production process by Inverted ＂U＂ Reduction-Distillation Connecting Art, the high-temperature valve should be operated by hand to drive the valve plate on the plug pole, by which the shortage is high intensity of labor and low productivity, so the high-temperature valve structure has been improved through experiments. The driving part has been changed from spiral to the rack-gear structure. According to the principle of movement, the hand wheel on spiral high-temperature valve rotates for once, the plug pole can only move for one screw pitch. Compared to the old one, the rack-gear valve rotates for once, the plug pole can move 3 times length of the diameter of the gear. Obviously, the new one gets higher efficiency. In fact, by using the rack-gear high-temperature valve, the productivity of spongc titanium was raised, and the cost was reduced. Therefore, it has been the finalized equipment.
