Flow guide pipe sealing device in distillation process of titanium sponge production

Abstract

The invention discloses a flow guide pipe sealing device in a distillation process of titanium sponge production. The sealing device comprises a cold-end large cover, a large cover heater flange, a transition flange, a passage assembly lower flange and a passage pipe upper flange, wherein the left end of the cold-end large cover is connected with a passage heater protection pipe, one side of the passage heater protection pipe is provided with a large cover heater, a conical pipe is arranged in the large cover heater, a heat preservation module is arranged above the conical pipe, a passage heater is arranged above the heat preservation module, a passage assembly is arranged above the passage heater, and a passage center pipe upper blind plate is fixed to the upper end of the passage assembly. According to the flow guide pipe sealing device in the distillation process of titanium sponge production, when a large-cover heater is maintained, cutting and welding operation is not needed, andthe large-cover heater can be maintained only by conveniently and rapidly loosening bolts.

Description

technical field [0001] The invention relates to the technical field of titanium sponge production, in particular to a sealing device for a draft tube in a distillation process used for titanium sponge production. Background technique [0002] An important stage in the production of titanium sponge by the Krall method is the distillation process. The distillation process is a separation method that utilizes the differences in certain physical properties of the components of the distillate. After the reduction process is completed, the hot end reactor and the cold end The reactors are connected by passages, and then heated by passage heaters and large cover heaters, and the process of distillation and impurity removal is carried out to obtain high-quality titanium sponge. The end reactor is connected through the passage flange, and then the connection between the passage flange of the hot end reactor and the passage flange of the cold end reactor is welded to ensure its tightn...

Problems solved by technology

At the same time, during the production process, the weld seam may sometimes burst due to the high temperature heating of the aisle heater, which not only needs to stop production, but also causes air intake to reduce product quality, and may cause an explosion in severe cases

[0003] The original large cover heater device seals the inside of the large cover heater by welding. During the production process, the large cover heater may be broken. When maintaining, the upper cover plate of the large cover heater must be cut and then It is repaired and then welded after the repair. In this process, it not only increases the labor load but also takes a lot of time, which affects the production efficiency. Therefore, we propose a distillation process diversion for the production of sponge titanium Tube Sealing Device
