Anti-blocking tube heating device for sponge production

Abstract

The invention discloses an anti-blocking tube heating device for sponge production. The heating device consists of a temperature measuring tube, a sleeve, a heat insulation layer, a sleeve flange, an inverse U-shaped connecting tube, an inverse U-shaped connecting tube flange, a U-shaped resistance wire, two heat radiation sleeves, a contact rod sleeve and a contact rod, wherein one end of the heat radiation sleeve is closed and provided with a pore communicated with the inverse U-shaped connecting tube at the position close to the inverse U-shaped connecting tube flange; the U-shaped resistance wire is arranged inside the heat radiation sleeve, the heat insulation layer is formed in the sleeve, and the sleeve is sealed through the sleeve flange and the inverse U-shaped connecting tube flange; and a U-shaped resistance wire binding post is connected with the contact rod, and the contact rod is sealed in the contact rod sleeve. The heating device effectively solves the problem that a passageway standpipe at the distillation stage of the titanium sponge production is blocked, shortens the distillation time, reduces the times of opening a condenser for examination, reduces the probability of air inlet pollution of a titanium sponge product, saves energy, reduces consumption, and prolongs the service life of the product by about 2 to 3 times.

Description

technical field [0001] The invention relates to a non-ferrous metal smelting technology, in particular to an anti-blocking pipe heating device used in the production of sponge titanium. Background technique [0002] Sponge titanium is the primary raw material in titanium alloy smelting. At present, the main method for industrial production of sponge titanium is the Kroll method. The basic principle of this method is to first use Mg and TiCl 4 The reduction reaction produces Ti, and then the excess Mg and the reaction product MgCl are removed by high-temperature vacuum distillation 2 And a small amount of titanium chloride, and finally get a spongy titanium lump. [0003] Inverted U-shaped combined furnace is currently the main furnace type for the production of sponge titanium. Its basic structure is to use an inverted U-shaped connecting pipe to connect the titanium-containing reactor and condenser. The inverted U-shaped connecting pipe is equipped with an aisle heater.
