Checking system for metering pump for titanium sponge manufacturing

Abstract

The invention discloses a checking system for a metering pump for titanium sponge manufacturing. The checking system for the metering pump for titanium sponge manufacturing comprises an overhead tank, the metering pump and a liquid collection tank, wherein the overhead tank is used for storing a titanium tetrachloride solution, and the height of the overhead tank is H1; the metering pump is connected with an outlet of the overhead tank and provided with at least two inlets and at least two outlets, and the height H2 of the metering pump is smaller than the height H1 of the overhead tank; an inlet of the liquid collection tank is connected with the metering pump, and a liquid level detecting device is arranged on the liquid collection tank and used for measuring the volume of the titanium tetrachloride solution in the liquid collection tank; and the charging amount of the metering pump each time is equal to the value obtained by dividing the volume of the titanium tetrachloride solution in the liquid collection tank by the number of charging times of a piston. According to the checking system for the metering pump for titanium sponge manufacturing, the metering pump can be checked accurately, the effect that the actual titanium tetrachloride solution charging amount is equal to the theoretical titanium tetrachloride solution charging amount in the titanium sponge production process is guaranteed, and normal and stable titanium sponge production is guaranteed; and the checking system is easy to operate, capable of saving energy and environmentally friendly, and no extra power source is needed.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a calibration system for metering pumps made of titanium sponge. Background technique [0002] In the process of producing sponge titanium by magnesia thermal reduction, magnesium and titanium tetrachloride are usually added to the sponge titanium reactor to react to generate sponge titanium, wherein titanium tetrachloride is added into the sponge titanium reactor through a metering pump, One stroke of the piston of the metering pump is one feeding. In actual production, the accuracy of the metering pump will decrease with the wear of the piston and spool of the metering pump. When there is a difference between the actual feeding amount of titanium tetrachloride and the theoretical feeding amount, it will seriously affect the reduction process of sponge titanium and Post-cleaning work, thereby reducing the product quality of titanium sponge. Therefore, it is particularly imp...
