（産業上の利用分野）
本考案は、流動塩化炉へ粉体原料を送り込むた
めの装置に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an apparatus for feeding powder raw material to a fluidized chlorination furnace.

スクリユーコンベアを用いて移送圧を減少させな
いようにしている。(Prior art) In order to feed powder raw materials of titanium oxide and carbon to a fluidized chlorination furnace, conventionally, the raw materials were poured into a duct from a raw material storage tank that was always maintained at a higher pressure than the pressure inside the furnace, and at the same time the raw materials were poured into a duct. For horizontal transfer, a screw conveyor is used to avoid reducing the transfer pressure.
（考案が解決しようとする問題点）
しかしながら上述の方法では、流動塩化炉の原

塩素が後工程で発生し作業環境を悪化させる。(Problems to be solved by the invention) However, in the above-mentioned method, chloride often grows and adheres to the inside of the duct near the raw material outlet of the fluidized chlorination furnace, causing the powder raw material to solidify and become unable to be transported. If this is left as it is, the titanium tetrachloride produced will contain chlorine (commonly known as free chlorine), and this free chlorine will be generated in the subsequent process, worsening the working environment.
そこで従来では、別途に振替えダクトを用意し
ておいて、上記事態に際し応急処置が採れるよう
にしておくとともに、日々ダクトの清掃を行なわ
なければならなかつた。 Therefore, in the past, a separate duct had to be prepared so that emergency measures could be taken in the event of the above situation, and the duct had to be cleaned on a daily basis.
（問題点を解決するための手段）
本考案は上記欠点を解決するためになされたも

れる。(Function) According to the above configuration, the powder raw material and the grown and deposited chlorides present in the duct near the raw material discharge port are stirred around inside the furnace by the rotating rod-shaped spiral body attached to the rotation drive shaft. Propulsive force is applied to the powder raw materials, etc., and they are smoothly fed into the furnace.

して他の材質を用いてもよい。 The reason why the rod-shaped spiral body 5 is made into a round rod shape is to reduce the outer surface area and prevent the adhesion of chlorides as much as possible. Further, the material of the rod-shaped spiral body 5 is not limited to Inconel 600, but other materials may be used in consideration of wear resistance and the like.

ものである。(Effects of the invention) As explained above, the present invention has a rod-shaped spiral body rotatably disposed in the duct near the raw material discharge port to the fluidized chlorination furnace, and this rod-shaped spiral body has one end attached to the rotation drive shaft. Since the powder raw material feeding device is configured by attaching it to the powder raw material feeder, it has an extremely simple structure, can be manufactured easily at low cost, and since the bearing is only at one end, the rotational driving force is small horsepower. The chloride and chloride are sent to the fluidized chlorination furnace while being stirred, which prevents the powder raw material from clogging that conventionally occurs near the raw material discharge port, and eliminates the hassle of cleaning work. It is something to play.
