Description
Technical Field
The utility model relates to a production device of titanium sponge, in particular to a device for judging a distillation production end point of the titanium sponge.
Background
The prior production of titanium sponge adopts the Claur method, furnace types are divided into a series furnace type and a parallel furnace type, in the production of the parallel furnace type, the production is divided into a reduction distillation production hot end system and a distillation production cold end system, the reduction distillation production hot end system mainly uses magnesium to reduce titanium tetrachloride to produce titanium and magnesium chloride, the distillation cold end system is used for collecting residual magnesium chloride and magnesium in the hot end system in a high vacuum state, the judgment of the distillation end point according to the distillation time and the distillation vacuum degree in the distillation process brings certain disadvantages, the distillation end point time can not be completely and accurately judged, if the judgment time is too early, the magnesium chloride in the hot end system is not distilled completely, so that the magnesium chloride impurity content in the titanium sponge product is high, the product quality is influenced, if the judgment is made later, the distillation time is too long, so that the distillation power consumption is increased, the production period is prolonged, and the production cost of the titanium sponge is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems that in the existing titanium sponge distillation production process, the distillation end point time cannot be completely and accurately judged, so that the magnesium chloride of a hot end system cannot be distilled cleanly, the impurity content of magnesium chloride in a titanium sponge product is high, the product quality is influenced, the distillation power consumption is increased, the production period is prolonged, and the production cost of the titanium sponge is increased.
In order to solve the technical problems, the utility model adopts the following technical scheme:
a decision maker for titanium sponge distillation production terminal, including locating the hot end large cover 2 on the upper portion of the hot end reactor 1, the hot end large cover 2 is connected with large cover 4 of cold junction through the vacuum cross-over pipe 3, there is a cold junction reactor 8 in the inferior part of the large cover 4 of cold junction;
a temperature measuring sleeve 6 is arranged on the cold end large cover 4, and a temperature measuring device 7 is arranged inside the temperature measuring sleeve 6;

Detailed Description
The present invention will be described in further detail with reference to the drawings, but it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments, and various modifications, substitutions and alterations made based on the knowledge and conventional practices of the ordinary skill in the art are included in the scope of the present invention without departing from the technical spirit of the present invention.
As shown in fig. 1, a device for determining the distillation production end point of titanium sponge comprises a hot end large cover 2 arranged at the upper part of a hot end reactor 1, wherein the hot end large cover 2 is connected with a cold end large cover 4 through a vacuum channel pipe 3, and a cold end reactor 8 is arranged at the lower part of the cold end large cover 4;
a temperature measuring sleeve 6 is arranged on the cold end large cover 4, and a temperature measuring device 7 is arranged inside the temperature measuring sleeve 6;
the distance between the temperature measuring sleeve 6 and the center of the cold end large cover 4 is 600mm, and the position is arranged according to the structure of the large cover, so that an operator can conveniently operate the temperature measuring device 7;
the temperature measuring device 7 consists of a temperature measuring tube and a thermocouple, and the bottom end of the thermocouple is contacted with the bottom of the temperature measuring tube;
the temperature measuring device 7 penetrates through the temperature measuring sleeve 6 and extends into the cold end reactor 8;
the distance between the bottom end of the temperature measuring device 7 and the cold end large cover bottom plate 5 is 500-800mm, according to the test, if the distance is less than 500mm, the temperature measured by the temperature measuring device 7 is affected by the internal heating temperature, the temperature error is judged to be large, and if the distance is more than 800mm, the temperature change in the cold end measuring reactor 8 is not obvious. The purpose of this is to determine the internal temperature of the cold-end reactor 8.
