この考案は、粉粒体が貯留タンク内で架橋する
ことを防止する粉粒体架橋防止装置に関する。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a powder crosslinking prevention device for preventing crosslinking of powder or granules in a storage tank.
（従来の技術）
例えば、石油や石炭を燃焼させた後の灰は、通
常、その処理過程において一旦貯留タンクに貯留
される。(Prior Art) For example, ash after burning oil or coal is usually temporarily stored in a storage tank during the treatment process.
ところで、上記のような石油の炭など粉粒体を
貯留すると、この粉粒体が貯留タンク内で架橋を
生じることがある。ここで、架橋とは貯留された
粉粒体が互いに連結し合つて粉粒体の排出口から
排出されないような現象をいい、この現象が生じ
れば、粉粒体を扱う装置の機能を阻害することと
なる。 By the way, when granular materials such as petroleum charcoal as described above are stored, the granular materials may cause crosslinking in the storage tank. Here, cross-linking refers to a phenomenon in which stored powder and granules are connected to each other and are not discharged from the powder and granule discharge port, and if this phenomenon occurs, it may impede the function of the device that handles the powder or granules. I will do it.
そこで、従来より、上記架橋を防止するために
種々の粉粒体架橋防止装置が提案されている。そ

つて粉粒体が流動化されて架橋の防止が行われて
いる。 Therefore, in order to prevent the above-mentioned crosslinking, various powder crosslinking prevention devices have been proposed. One example is one in which an air slide is provided on the bottom surface of the storage tank, extending along the bottom surface and toward the discharge port. This air slide is usually
It has a permeable perforated plate provided along the bottom surface of the storage tank, through which compressed air is blown into the storage tank. The air fluidizes the powder and prevents crosslinking.

る。(The serious problem that the invention aims to solve) However, the friction and adhesion between powder and granules, such as the above-mentioned petroleum ash, and between the powder and the tank wall are large. If the granules are compressed by their own weight during storage, even if air is blown into the granules using an air slide, the air will not flow uniformly within the granules, and some of the air will flow unevenly. Sometimes. In this case, a flow path (so-called rat hole) for air to blow through from the bottom side to the top side of the storage tank is formed between the powder and granules, and the air is simply discharged through this flow path. Become. In other words, if such a phenomenon occurs, the powder or granules will not be fluidized, and as a result, crosslinking will not be prevented.
（考案の目的）

互いに交差させた点にある。(Structure of the device) The features of this device for achieving the above object include the provision of a horizontal shaft that reciprocates in the axial direction near the top of the air slide provided on the bottom of the storage tank, and a horizontal shaft that reciprocates in the axial direction. On the other hand, a vertical shaft whose lower end is located near the discharge port of the powder and granular material and reciprocates in the axial direction is provided, and a second stirring projection is provided on this vertical shaft, and both of the shafts are oriented vertically. The two axes are arranged in substantially the same plane, and are located at a point where both axes intersect with each other when viewed from the side.
（作用） 上記構成による作用は次の如くである。(effect) The effects of the above configuration are as follows.
貯留タンク１内に横軸１４を設けた場合には、
この横軸１４はその上方に貯留された粉粒体の自
重による負荷を支持することになる。そして、こ
の横軸１４はエアスライド８の上方近傍に位置し
ているため、この横軸１４からエアスライド８に
至る間の粉粒体がその自重によつて圧縮されるこ
とが防止される。 When the horizontal shaft 14 is provided in the storage tank 1,
This horizontal shaft 14 supports the load due to the weight of the powder and granules stored above it. Since the horizontal shaft 14 is located near the top of the air slide 8, the powder and granular material between the horizontal shaft 14 and the air slide 8 is prevented from being compressed by its own weight.
よつて、エアスライド８によりこの粉粒体内に
空気を吹き込んだときには、この空気は偏流する
ことなく比較的均一にこの粉粒体内を流れること
になり、このため、エアスライド８上の粉粒体は
効果的に流動化させられることになる。 Therefore, when air is blown into the powder body by the air slide 8, the air flows relatively uniformly within the powder body without drifting, and therefore the powder body on the air slide 8 will be effectively liquefied.

よりこの流動化は更に効果的に促進される。 Moreover, in this case, the horizontal shaft 14 is the first stirring protrusion 1
8 and 18', the powder and granules are fluidized by the first stirring protrusions 18 and 18', and the air, which is located near the horizontal shaft 14 as described above, This fluidization is further effectively promoted by the air from the slide 8.

する縦軸２２の下端は排出口６の近傍に位置して
いるため、第２撹拌突起２３で流動化された粉粒

る。 On the other hand, since the lower end of the vertical shaft 22 that reciprocates in the axial direction together with the second stirring protrusion 23 is located near the discharge port 6, the powder fluidized by the second stirring protrusion 23 passes through the discharge port 6. It will be discharged smoothly.

生じることが抑制される。 Further, the horizontal axis 14 and the vertical axis 22 are disposed in substantially the same vertical plane, and both axes 1
4 and 22 intersect with each other in a side view, so that the powder particles in the storage tank 1 are separated by the fluidized bed of powder fluidized by the shafts 14 and 22 and the stirring protrusions 18 and 23. The body is almost divided into left and right sides. Therefore, the occurrence of a crosslinking phenomenon between the left and right powder bodies is suppressed.

ととなる。 Further, since the horizontal axis and the vertical axis are disposed in substantially the same vertical plane, and these two axes intersect with each other in a side view, the liquid is not fluidized by the two axes and the stirring protrusion. The powder and granules in the storage tank are almost divided into right and left sides with the fluidized bed of the granules as a boundary. Therefore, the occurrence of a bridging phenomenon between the left and right powder particles is suppressed, and from this point of view as well, the powder particles can be discharged extremely smoothly.
