Abstract
The invention relates to an aluminum powder adding device for removing vanadium from aluminum powder. The device comprises an aluminum powder mixing tank, an aluminum powder charging port, an aluminum powder charging tank and a nitrogen inlet, wherein the aluminum charging tank is arranged between the aluminum mixing tank and the aluminum powder charging port, and the nitrogen inlet is arranged on the aluminum charging tank. In the invention, the operation of adding the aluminum powder is simple, and the nitrogen protection in the aluminum powder charging tank enables the process of adding aluminum powder to be safe and reliable.
Description
Technical field
The present invention relates to a kind of is that reductive agent is removed in the vanadium impurity from titanic tetrachloride process with the aluminium powder, and aluminium powder removes the aluminium powder adding apparatus of vanadium.
Background technology
Titanium tetrachloride is a raw material of producing titanium sponge and chlorination process production titanium white, and the foreign matter of vanadium in the crude titanic chloride is mainly with VOCl
3Form exists, and its boiling point (127.2 ℃) is close with titanium tetrachloride boiling point (136.2 ℃), if adopt rectificating method little because of separation factor, is difficult to it is removed from titanium tetrachloride, so many aborning employing chemical processes are removed vanadium.Adopting aluminium powder among the present invention is that reductive agent is removed the foreign matter of vanadium in the crude titanic chloride.The mode of aluminium powder adding in the past is the vacuum pump suction, because the aluminium powder that adopts is a superfine aluminium power in this technology, so with vacuum pump suction aluminium powder the time, suction line is easy to be stopped up by aluminium powder, and in a single day aluminium powder enters vacuum pump system and cause danger easily.
Summary of the invention
The purpose of this invention is to provide the aluminium powder adding apparatus that a kind of aluminium powder removes vanadium, make simple to operately, feasible, making with the aluminium powder is that reductive agent removes that the process of foreign matter of vanadium reaches serialization in the crude titanic chloride.
Adopt following scheme for reaching above purpose the present invention,
Aluminium powder of the present invention removes the aluminium powder adding apparatus of vanadium, comprises the aluminium powder mixing tank, and wherein: be provided with the aluminium powder feed pot between aluminium powder mixing tank and the aluminium powder charging opening, the aluminium powder feed pot is provided with nitrogen inlet.
Aluminium powder of the present invention adds simple to operate, because there is nitrogen protection to make aluminium powder adition process safety, reliable in the aluminium powder feed pot.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. aluminium powder mixing tank; 2. aluminium powder feed pot; 3. nitrogen inlet; 4. aluminium powder charging opening.
Embodiment
As shown in Figure 1, the present invention includes aluminium powder mixing tank 1, be provided with aluminium powder feed pot 2 between described aluminium powder mixing tank 1 and the aluminium powder charging opening 4, also be provided with nitrogen inlet 3 on the described aluminium powder feed pot 2.
Above aluminium powder mixing tank 1, increase an aluminium powder feed pot 2, behind nitrogen purging aluminium powder feed pot 2, manually in aluminium powder feed pot 2, add aluminium powder, open pipe valve (not shown) at the bottom of the aluminium powder feed pot jar then, the aluminium powder in it is added to aluminium powder mixing tank 1.
Claims (1)
1. an aluminium powder removes the aluminium powder adding apparatus of vanadium, comprises the aluminium powder mixing tank, and it is characterized in that: be provided with the aluminium powder feed pot between aluminium powder mixing tank and the aluminium powder charging opening, the aluminium powder feed pot is provided with nitrogen inlet.
