【発明の詳細な説明】
本発明は、ニーグー等の混合機における混合羽根に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mixing blade in a Nigu mixer.
ぎ般に混合機によって各種材料を混合する場合、材料同
士又は材料と混合羽根との摩擦により材料が発熱するこ
とが多く、混合時にこれを冷却する必要がある。Generally, when various materials are mixed using a mixer, the materials often generate heat due to friction between the materials or between the materials and the mixing blade, and it is necessary to cool the materials during mixing.
又、逆に高温下において混合するような場合には、加熱
する必要がある場合も少なくない。On the other hand, when mixing at high temperatures, heating is often necessary.
このような場合には、混合機の容器を冷却又は加温する
のであるが、直接材料と接触する混合羽根を冷却又は加
温するのが好ましく、この場合は、混合羽根を中空状と
して該中空部に冷却水又は加圧水蒸気等を通して行なう
。In such a case, the container of the mixer is cooled or heated, but it is preferable to cool or heat the mixing blade that comes into direct contact with the material.In this case, the mixing blade is hollow and the hollow Cooling water or pressurized steam is passed through the area.
而して、このように内部を中空形状とした混合羽根の構
造としては、その肉厚中心に沿ってキリ穴加工を施した
もの、鋳造時に金属管を鋳包みした構造のもの等が考え
られるが、前者においては、複雑に折れ曲がった混合羽
根にキリ穴加工を施すのは極めて困難であり、製造上の
困難さを考えると後者の方が望ましい。Therefore, the structure of a mixing blade with a hollow interior as described above may include one in which a drilled hole is machined along the center of the wall thickness, or one in which a metal tube is cast-in during casting. However, in the former case, it is extremely difficult to drill holes in the intricately bent mixing blade, and the latter is more desirable in view of manufacturing difficulties.
しかしながら、この後者の構造においても、その鋳造時
において、溶湯の熱により管が熔解することが多く、溶
湯が管内に流入し、管を閉塞したり流路を狭めるという
製造上の不都合がある。However, even in this latter structure, during casting, the tube often melts due to the heat of the molten metal, and the molten metal flows into the tube, causing manufacturing problems such as blocking the tube and narrowing the flow path.
管の肉厚を充分に厚くすれば、管の熔解は防止できるが
、溶湯を注入した際に管の外面のみが急激に加熱される
こととなり、管の内外に大きな温度差が生じ、歪や亀裂
が生じることがあり、これとても好ましい結果は得られ
ない。If the wall thickness of the tube is made sufficiently thick, it is possible to prevent the tube from melting, but when molten metal is injected, only the outer surface of the tube is rapidly heated, creating a large temperature difference between the inside and outside of the tube, which can cause distortion and distortion. Cracks may form and this is not a very desirable result.
本発明は、かかる事情に鑑みなされたものであって、金

金を、金属管の円周方向に複数個固着するように構成し

る中空羽根の構造を提供せんとするものである。The present invention has been made in view of the above circumstances, and includes a structure in which a plurality of rod-shaped chillers are fixed to the outer periphery of a metal tube along the longitudinal direction of the metal tube in the circumferential direction. Therefore, it is an object of the present invention to provide a hollow blade structure in which a metal tube can be cast without causing melt damage.

混合羽根８は、この金属管１の内腔６によって中空部を
有している。Hereinafter, the configuration of the present invention will be explained based on a drawing showing an example. FIG. 1 shows a sigma type mixing blade according to the present invention, and in the shape of such a mixing blade 8, inside thereof, As shown in FIG. 1C, a metal tube 1 extending in the longitudinal direction is embedded, and this metal tube 1 communicates with a hole 5 for inserting a shaft 9 bored at both ends, and is provided over the entire length.
The mixing vane 8 has a hollow portion formed by the lumen 6 of the metal tube 1 .

れている。This FIG. 4 shows an example of the state in which the mixing blade 8 and the shaft 9 obtained in this way are connected. A concave groove 11 is formed on the outer periphery of the distal end, and a through hole 12 is bored from the concave groove 11 to the communication hole 10.
シャツｌ−９を混合羽根８に結合した状態においては、
凹溝１と凹溝１１とが一致し、そこに流路１３が形成さ

における位置のズレを吸収しつるのである。In the state where the shirt l-9 is connected to the mixing blade 8,
The concave groove 1 and the concave groove 11 coincide with each other, and a flow path 13 is formed therein, thereby absorbing the positional deviation when the shaft 9 is inserted.

The flow path 1 passes through the communication hole 10 of the shaft 9 and passes through the through hole 12.
3, from where it flows into the lumen 6 of the tube embedded in the vane 8, through which it cools the mixing vane 8, and exits from the other end.
以上の如く、本発明においては、金属管の周囲に冷やし
金を固着しているので、羽根を鋳造する際に、管が溶湯

に確保される。As described above, in the present invention, since the cooling metal is fixed around the metal tube, the tube will not melt due to the heat of the molten metal when casting the blade, and the flow path for cooling water etc. will be sufficient. will be secured.

や引は巣が減少するという製造上の利点がある。In addition, since there is no need to make the wall thickness of the pipe thicker than necessary, distortion and cracks will not occur.Furthermore, by providing the cooling metal in this way, the wall thickness of the cast part becomes thinner, so that only the pipe can be used. It has the manufacturing advantage of reducing cracks and cavities during casting compared to when it is cast-in.
