【考案の詳細な説明】
本考案は、水や油などのような液体に微粉末を
混合して懸濁液または溶液を製造する工程で用い
る、混合装置の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a mixing device used in the process of mixing fine powder with a liquid such as water or oil to produce a suspension or solution.
先ず、水に微細な黒鉛粉末を懸濁させた導電性
塗料を製造する場合を例として説明すると、従来
は混合容器内の水をインペラなどの適宜の手段で
攪拌しておき、そこに黒鉛微粉を少しずつ、水面
上から投入するのが一般的であつた。（塗料には
他に多くの成分が含まれるが、以下は話を簡単に
するため、水と黒鉛微粉に限定して説明する。）
しかし、この混合方法では粉末がままこになり
易く、そのため容器の内壁に凝着したり、分散に
長時間を要するばかりでなく、黒鉛のような軽い
微粉末の場合には、投入時にその一部が飛散して
しまうという問題があつた。 First, let's take an example of manufacturing a conductive paint by suspending fine graphite powder in water. Conventionally, water in a mixing container is stirred using an appropriate means such as an impeller, and then fine graphite powder is added to the water in a mixing container. It was common practice to introduce water little by little from above the water surface. (Paints contain many other ingredients, but for the sake of simplicity, we will limit the discussion to water and fine graphite powder.) However, with this mixing method, the powder tends to clump together; Not only do they adhere to the inner wall of the container and require a long time to disperse, but in the case of light fine powder such as graphite, there are problems in that part of it scatters when it is added.
本考案はこの様な事情に基づいてなされたもの
であつて、粉末の供給口を混合容器の底部または
側壁に設け、容器内で攪拌されている液体の水面
より下の位置から粉末を供給することをその骨子
とするものである。 The present invention was developed based on these circumstances, and the powder supply port is provided at the bottom or side wall of the mixing container, and the powder is supplied from a position below the water surface of the liquid being stirred in the container. This is the main point.
実施例
以下本考案を、その一実施例を示す第１図につ
いて詳細に説明する。Embodiment Hereinafter, the present invention will be explained in detail with reference to FIG. 1 showing one embodiment thereof.
図において１は混合容器で、攪拌用のインペラ
２とこれを駆動するモーター３、混合された液体
の排出管４とその開閉弁４ａを具えている点は、
従来の混合装置と同様である。ただしインペラが
２ａ，２ｂと上下２段に設けられている点に工夫
があるが、その理由は本考案の特徴とする構成と
密接な関係にあるので、それについては後述す
る。下方が円錐状の粉体ビン５も、それ自体は従
来のものと同様であつて、従来はこのビン５が混
合容器１の上方に設けられた訳である。なお、６
は粉末の排出管、６ａはその開閉弁である。 In the figure, 1 is a mixing container, which is equipped with an impeller 2 for stirring, a motor 3 for driving it, a discharge pipe 4 for the mixed liquid, and an on-off valve 4a for the mixed liquid.
Similar to conventional mixing equipment. However, there is a contrivance in that the impellers are provided in two stages, upper and lower, 2a and 2b, but the reason for this is closely related to the feature of the present invention, and will be described later. The powder bottle 5 having a conical lower part is also similar to the conventional powder bottle 5, and conventionally, the powder bottle 5 is provided above the mixing container 1. In addition, 6
is a powder discharge pipe, and 6a is its opening/closing valve.
本考案の特徴は粉末を混合容器の水面下の位置
で、好ましくは下段のインペラ２ｂの下側で供給
することにあり、その手段として空気コンベアー
が用いられる。即ち、粉体ビンの排出管６に空気
コンベアー７を接続し、その出口は、この実施例
においては混合容器１の底に開口している。８は
空気コンベアーを駆動する圧縮空気配管で、その
主管路は空気コンベアー７に直結し、粉体ビン５
の上部と円錐部にも吹き出し口を分岐している。 The feature of the present invention is that the powder is supplied to the mixing container at a position below the water surface, preferably under the lower impeller 2b, and an air conveyor is used as a means for this purpose. That is, an air conveyor 7 is connected to the discharge pipe 6 of the powder bin, the outlet of which opens at the bottom of the mixing vessel 1 in this embodiment. 8 is a compressed air pipe that drives the air conveyor, its main pipe is directly connected to the air conveyor 7, and the powder bin 5
There are also branched air outlets at the top and conical part.
ビンの上部への配管は、ビン内の気圧の平衡を
図り、粉末の流れを良くするためであり、また、
ビンの円錐部への配管はビン内に堆積した粉末の
流動化を促進し、その架橋を予防および解消する
ために設けたものである。なお９ａ〜９ｄは管路
各部の開閉弁である。 The purpose of piping to the top of the bottle is to balance the air pressure inside the bottle and improve the flow of powder.
The piping to the conical part of the bottle is provided to promote fluidization of the powder accumulated in the bottle and to prevent and eliminate bridging. Note that 9a to 9d are on-off valves for each part of the pipeline.
次にこの装置で混合を行なう場合は、先ず各開
閉弁４ａ，６ａおよび９ａ〜９ｄを閉じた状態で
混合容器１には水を、粉体ビン５には黒鉛微粉の
各所定量を入れ、粉体ビンはその蓋５ａを閉じて
密閉する。そしてインペラ２（２ａおよび２ｂ）
を回転させて混合容器内の水を攪拌させておく一
方、弁９ａ，９ｂを開いて圧縮空気をビン５内に
導入する。 Next, when mixing is performed using this device, first, with the on-off valves 4a, 6a, and 9a to 9d closed, water is poured into the mixing container 1, and predetermined amounts of fine graphite powder are poured into the powder bottle 5, and the powder is The body bottle is sealed by closing its lid 5a. and impeller 2 (2a and 2b)
is rotated to stir the water in the mixing container, while valves 9a and 9b are opened to introduce compressed air into the bottle 5.
次いで空気コンベアー７の前後の開閉弁９ｃ，
９ｄを開くと、粉体ビン５の中の黒鉛微粉は圧縮
空気によつて管路内を一定速度で搬送され、その
出口から混合容器１内に空気と一緒に噴出する。 Next, the on-off valves 9c before and after the air conveyor 7,
When 9d is opened, the fine graphite powder in the powder bin 5 is conveyed at a constant speed through the pipe by compressed air, and is ejected from the outlet into the mixing container 1 together with air.
ところでこの際に生じる気泡はかなり大きく、
黒鉛微粉の相当量はこの気泡に吸着された状態で
存在するが、気泡が大きいと直線的に水面に浮上
し、水面に浮かんだ粉末同志が凝集して分散が困
難になる。そこで、下段のインペラ２ｂは気泡の
剪断に適する形状に作られていて、大きな気泡は
インペラ２ｂの作用によつて細かい無数の気泡に
分断され、攪拌用インペラ２ａの回転による水流
中に混じり合い、攪拌作用を促進して粉末の分散
を助けた後に水面から大気中に戻る。つまりこの
装置では、圧縮空気は粉末の搬送とその分散の、
一石二鳥の働きをする訳である。 By the way, the bubbles that occur at this time are quite large,
A considerable amount of fine graphite powder exists in a state adsorbed by the bubbles, but if the bubbles are large, they float straight to the water surface, and the powder floating on the water surface aggregates, making it difficult to disperse. Therefore, the lower impeller 2b is made in a shape suitable for shearing the bubbles, and the large bubbles are divided into countless fine bubbles by the action of the impeller 2b, which are mixed into the water flow caused by the rotation of the stirring impeller 2a. It promotes agitation and helps disperse the powder before returning from the water surface to the atmosphere. In other words, in this device, compressed air is used for transporting powder and dispersing it.
In other words, it kills two birds with one stone.
また、この様な作用効果を図ることがインペラ
を水流形成を主とする２ａと、気泡の細分を主と
する２ｂとの上下２段に構成した理由であつて、
従つて混合容器への粉末の供給は剪断インペラの
作用が最も強力に及ぶ場所で、即ち、図示の如く
インペラ２ｂの直下で行なうのが最適である。 In addition, aiming for such an effect is the reason why the impeller is configured in two stages, upper and lower, 2a mainly for forming water flow and 2b mainly for dividing air bubbles.
Therefore, it is best to feed the powder into the mixing container at a location where the action of the shearing impeller is most powerful, ie, directly below the impeller 2b as shown.

While the conventional mixing method of adding powder little by little took 90 minutes to mix, the device of this invention only takes 30 minutes, reducing the required time to one-third. Obtained. Moreover, since the powder in the liquid was completely dispersed, there was no need to filter out the mako.

It is also possible to use a gas that has
