Uniform, accurate and high-precision titanium tetrachloride feeding method

Abstract

The invention discloses a uniform, accurate and high-precision titanium tetrachloride feeding method, and relates to the technical field of sponge titanium production. The following devices are specifically adopted and comprise a peristaltic pump, a valve head A, a valve head B, a valve head C, a valve head D, special material pipes, a storage tank, a feeding valve A, a feeding valve B, a feeding valve C and reaction kettles. According to the uniform, accurate and high-precision titanium tetrachloride feeding method, titanium tetrachloride can be conveyed to the corresponding reaction kettles at a constant speed through cooperation between the peristaltic pump and the valve heads, and the technical problem that the feeding speed is nonuniform and inaccurate in the titanium sponge production process is successfully solved; and the aim that the single peristaltic pump controls the multiple reaction kettles at the same time can be achieved, the stability of product quality is effectively improved, rubber hoses and tightening springs are arranged, so that the inner diameter sizes of the rubber hoses are automatically changed along with the conveying amount of titanium tetrachloride, titanium tetrachloride can be stably conveyed, and the interrupted phenomenon cannot happen.

Description

technical field [0001] The invention relates to the technical field of titanium sponge production, in particular to a uniform, accurate and high-precision titanium tetrachloride feeding method. Background technique [0002] An important stage in the production of sponge titanium by the Krall method is the reduction process. The reduction process is a process in which a raw material magnesium reacts with another raw material titanium tetrachloride to produce sponge titanium and a by-product magnesium chloride. Before the reduction reaction, the raw material magnesium is directly added In the reactor, another raw material, titanium tetrachloride, is continuously fed into the reactor through a feed pipeline through a high-level tank. [0003] In the feeding process of existing titanium tetrachloride, the feeding speed is stable, uniform and accurate, which has a great influence on the product quality. Generally, the rotameter is used to control the feeding speed, but the feedin...
