Description
【考案の詳細な説明】
(産業上の利用分野)
この考案は、高濃度石炭、水混合燃料(以下
CWMという。)の貯蔵タンクに関する。[Detailed explanation of the invention] (Industrial application field) This invention is a highly concentrated coal, water mixed fuel (hereinafter referred to as
It's called CWM. ) related to storage tanks.
(従来の技術)
CWMは、粒度200メツシユパス率80%程度の
微粉炭に水および添加剤を加え、高濃度(石炭濃
度80%程度)のスラリー状にした流体燃料であ
る。(Prior technology) CWM is a fluid fuel made by adding water and additives to pulverized coal with a particle size of 200 and a mesh pass rate of about 80% to form a highly concentrated slurry (coal concentration of about 80%).
ところでCWMは固液分散系であるので、貯蔵
期間によつては比重差のため上下層のスラリー濃

層部のスラリー濃度をできるだけ均一に保つため
に、タンク内のスラリーを撹拌することが必要で
ある。また、冬期の凍結、直射日光による局部温
度の上昇および昼夜の気温差等、タンク内温度に
対する配慮が必要である。 By the way, since CWM is a solid-liquid dispersion system, there will be some difference in slurry concentration between the upper and lower layers due to the difference in specific gravity depending on the storage period. Therefore, it is necessary to stir the slurry in the tank in order to keep the slurry concentration at the bottom and top of the tank as uniform as possible. In addition, consideration must be given to the temperature inside the tank, such as freezing in winter, local temperature increases due to direct sunlight, and temperature differences between day and night.

撹拌するものである。 Conventionally, various types of storage tanks have been employed, one of which is shown in FIG. 3. This storage tank is provided with a side mixer 2 driven by a motor at the lower side of the tank, and the slurry in the tank 1 is stirred by the action of the side mixer 2.

く、設備費が膨大となる欠点があつた。(Problem that the invention aims to solve) However, in the conventional storage tank, in order to stir the slurry in the entire tank, it is necessary to install a large capacity motor and mixer, or to significantly increase the number of motors and mixers. There is. Therefore, not only the tank and auxiliary equipment become large, but also the equipment cost becomes enormous.

出するパイプを配設してなることを特徴とする。(Means for solving the problem) The main structure of this invention is to provide a side mixer driven by a motor on each level of the inner surface of the tank, and an opening in the tank covers the side mixer. It is characterized by a pipe that extends along the sides and extends to the bottom of the tank.
(実施例)
以下、この考案を図面に示す実施例に基いて説
明する。(Example) This invention will be described below based on an example shown in the drawings.

取り付けられている。 As shown in Fig. 1, side mixers 2 are provided at the upper, middle, and lower levels of the inner surface of the tank 1, and the same number of side mixers 2 as side mixers 2 are provided on the outer surface of the tank 1. It is driven by a motor 3. Inside the tank 1 is a pipe 4 extending vertically along the side of the tank 1.
A plurality of pipes 4 are arranged, and the upper opening of each pipe 4 is attached so as to cover the side mixer 2, and the lower opening is attached so as to be located at the center of the bottom of the tank 1.
従つて、最も液面に近いサイドミキサー2を駆

に対流を生じさせることができるので、同様に濃
度の均一化を達成できた。 Therefore, by driving the side mixer 2 closest to the liquid level, the thinner upper slurry can be effectively blown into the thicker bottom slurry,
The concentration of CWM can be made uniform. Also, if all side mixers 2 are driven, the CWM in tank 1
Since convection can be generated between the two, it was also possible to achieve uniform concentration.
なお、実施例ではサイドミキサー2を3基使用
しているが、タンク1の容量に合わせてより多く
(5〜6基)使用してもよい。 Although three side mixers 2 are used in the embodiment, more (5 to 6) may be used depending on the capacity of the tank 1.
(考案の効果)
モータおよびミキサの容量を大型化する必要
がないため、設備費、稼動コストが安価であ
る。(Effects of the invention) Since there is no need to increase the capacity of the motor and mixer, equipment costs and operating costs are low.
上層のスラリーを底部のスラリーに効果的に
送り込むことができると共に、タンク内のスラ
リーに対流を生じさせることができるので、
CWMの濃度を容易に均一化できる。 The slurry in the upper layer can be effectively sent to the slurry in the bottom layer, and convection can be created in the slurry in the tank, so
The concentration of CWM can be easily made uniform.
サイドミキサーは各レベルに設けられている
ので、液位の変動にも対応できる。 Side mixers are installed at each level, so they can respond to fluctuations in liquid level.
