Description
【０００１】[0001]
本考案は、鋸屑、鋸屑様の木屑または穀物等の粉体あるいは粒状物質を貯蔵物 とし、容器上部から投入し、下部から排出する構造を有する粉粒体の貯槽に関す る。 The present invention relates to a storage container of powder and granules having a structure in which a powder or granular substance such as sawdust, sawdust-like wood waste, or grains is used as a storage material, and is charged from the upper part of the container and discharged from the lower part.
【０００２】[0002]
従来より、粉体あるいは粒状物質等を貯蔵物とする自重排出式の貯槽では、こ れら取り扱う貯蔵物の物性によって、貯蔵物が槽内でラットホールやブリッジを 形成し、閉塞現象が生じることが知られている。 Conventionally, in self-weight discharge type storage tanks that store powder or granular materials, etc., due to the physical properties of the stored materials that are handled, the stored materials form ratholes or bridges in the tank and blockage phenomenon occurs. It has been known.
【０００３】 このため、閉塞防止と閉塞解除について、特にホッパー等の下部断面を下方に ゆくにつれて縮小した漏斗状容器にみられるように、排出を補助すべく貯槽壁に バイブレータを取りつけて流動性を高めたり、貯槽壁から圧縮空気を噴射してブ リッジ現象により形成されたアーチを破壊し、流動の渋滞を解消する試みがあっ た。Therefore, for blocking and unblocking, a vibrator is attached to the wall of the storage tank to assist discharge, as seen especially in a funnel-shaped container that is reduced as the lower cross section of the hopper or the like is moved downward. Attempts have been made to increase the flow rate or to inject compressed air from the tank wall to destroy the arch formed by the bridge phenomenon and eliminate the flow congestion.
【０００４】 また、鋸屑等を貯蔵物とした貯槽に関しては、排出装置に依存しながら排出の 円滑を期すこともあり、本出願人が提供した公知例（特許第９５４５４５号）も その１つである。Further, regarding a storage tank that stores sawdust or the like, depending on the discharge device, discharge may be smoothed, and a known example provided by the present applicant (Japanese Patent No. 954545) is one of them. is there.
【０００５】[0005]
しかしながら、比較的水分含有量が高く、しかも、粉粒内の内部摩擦が大きい 鋸屑等の貯蔵物は、特に付着性が高くブリッジ現象を生じ易いため、上記した補 助装置を設けたとしても十分に役立たない場合があり、逆に、振動による充填作 用で閉塞を助長したり、圧縮空気による粉粒の飛散を来すなど逆効果を生じる場 合もあった。また、サイロ等の一時貯蔵を主目的とする貯槽や上記排出装置の上 部構造としての貯槽にあっては、断面減少をともなわないストレートな貯槽内で も、貯蔵物の圧密により、壁面方向へも圧力が増大し、ブリッジの支持部を形成 するという問題があった。 However, stored materials such as sawdust, which has a relatively high water content and large internal friction in the powder particles, are particularly adherent and easily cause a bridging phenomenon. Therefore, even if the above-mentioned auxiliary device is provided, it is sufficient. In some cases, it may not be useful, and on the contrary, there may be a case where a filling operation due to vibration promotes blockage, or powder particles are scattered by compressed air, which has the opposite effect. In addition, for storage tanks mainly for temporary storage such as silos and storage tanks as the upper structure of the above-mentioned discharge device, even in a straight storage tank that does not cause a reduction in cross-section, due to the compaction of the stored materials, However, there was a problem that the pressure increased and the bridge support was formed.
【０００６】 さらに、この種の貯槽は、比較的大容量の貯溜とされる場合が多く、ここでは 下方にゆくにつれて貯蔵物の下部が圧密され、排出に際して、貯蔵物が局所的に 払い出されたり、偏載が生じたりして閉塞現象を助長し、排出できなくなるとと もに、貯槽壁面の局所的な応力が増大し、貯槽の破損を引き起こすという問題が あった。[0006] Furthermore, this type of storage tank is often a relatively large-capacity storage, in which the lower part of the stored material is consolidated as it goes downward, and the stored material is locally discharged when discharged. In addition, there are problems that the blockage phenomenon is promoted due to uneven distribution, and it becomes impossible to discharge it, and the local stress on the wall surface of the storage tank increases, causing damage to the storage tank.
【０００７】 本考案は、このような事情に鑑みなされたものであって、上記問題点を解消す べく、貯蔵物の流動が円滑で、ブリッジ現象を防止する構造を有した粉粒体の貯 槽を提供することを目的とするものである。The present invention has been made in view of the above circumstances, and in order to solve the above-mentioned problems, the storage of a granular material having a structure in which a stored material flows smoothly and a bridge phenomenon is prevented. It is intended to provide a tank.
【０００８】[0008]
上記目的を達成するために本考案は、上部に投入口と下部に排出口を有する粉 粒体用容器において、貯槽内部に貯槽壁の壁面に沿って鉛直下方に指向する複数 条のガイドリブを設けるとともに、このガイドリブが、これを見込む貯槽の縦断 面を下方に指向して拡大すべく、テーパを有して形成されたことを特徴とするも のである。 In order to achieve the above-mentioned object, the present invention provides a container for granules having an inlet at an upper portion and an outlet at a lower portion, and provided with a plurality of guide ribs vertically downward along the wall surface of the reservoir wall inside the reservoir. At the same time, the guide ribs are formed so as to have a taper so as to extend downward by directing the longitudinal cross section of the storage tank, which looks into the guide ribs, downward.
【０００９】[0009]
貯槽から粉粒体を自重により自然流出させると、流動速度は、貯槽の中央部で 最も速くなり、貯槽内壁面で最も遅くなる。閉塞は、この壁面と粉粒体の付着を 支持部として発生するブリッジやラットホールに拠るものである。 本考案による貯槽の内部構造は、壁面に沿って鉛直下方に指向して設けられた ガイドリブが、これを見込む貯槽の縦断面を下方に指向して拡大するようにテー パを有して形成されているので、この表面および断面構造になる形状効果により 、貯蔵物の流動を円滑にさせる。また、これにより付着が阻止されるので、ブリ ッジやラットホールの支持部が形成されない。 When the granular material is naturally discharged from the storage tank by its own weight, the flow velocity becomes highest in the central part of the storage tank and slowest in the inner wall surface of the storage tank. The blockage is due to the bridges and rat holes that are generated by the adherence of the powder and granules to the wall surface as a supporting part. The internal structure of the storage tank according to the present invention is formed such that the guide ribs provided vertically downward along the wall surface have the taper so that the vertical cross section of the storage tank, which looks into this, is enlarged downward. Therefore, the shape effect of this surface and cross-sectional structure facilitates the flow of the stored material. Further, this prevents the adhesion, so that the support portion for the bridge and the rat hole is not formed.

【実施例１】 本考案の１実施例について添付図面を参照して以下説明する。 図１は、円筒形に具現された貯槽の横断面図であり、図２は、貯槽の縦断面図 （ガイドリブを見込む縦断面として先述した。）である。 図において、１が貯槽内壁、２が投入口、３が排出口４が粉粒体および５がガ イドリブである。Embodiment 1 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a horizontal cross-sectional view of a storage tank embodied in a cylindrical shape, and FIG. 2 is a vertical cross-sectional view of the storage tank (described above as a vertical cross-section looking into the guide ribs). In the figure, 1 is an inner wall of a storage tank, 2 is an inlet, 3 is an outlet 4, a granular material, and 5 is a guide rib.
【００１１】 ここでは、部材の板厚は省略し線図としている。また、以下では、貯槽の内部 構造の要部のみを説明し、他の部分、例えば供給・排出および各種調整・制御に ついては、説明を省略する。Here, the plate thickness of the member is omitted in the diagram. In the following, only the main part of the internal structure of the storage tank will be described, and description of other parts, such as supply / discharge and various adjustments / controls, will be omitted.
【００１２】 本考案を具現した円筒形貯槽の内壁（１）を、壁面に沿って鉛直下方に指向し たガイドリブ（５）を、貯槽壁（１）内周に対向して設ける。 このガイドリブ（５）は、貯槽の縦断面を下方に指向して拡大するように、テ ーパを有したものとされる。また、この部材の１例を図３に示すとおり、三角形 の２辺による突起とするのが実証的に好ましいが、これにこだわるものではない 。The inner wall (1) of the cylindrical storage tank embodying the present invention is provided with guide ribs (5) directed vertically downward along the wall surface so as to face the inner circumference of the storage tank wall (1). The guide rib (5) has a taper so that the longitudinal section of the storage tank is directed downward and expands. Further, as shown in FIG. 3, an example of this member is empirically preferred to be a protrusion having two sides of a triangle, but the present invention is not limited to this.
【００１３】 このように構成された貯槽は、断面形状（図１および図２）からもわかるよう に、貯蔵物を外力とした貯槽壁の局部的応力を緩和するとともに、構造的な補強 としても寄与するものである。As can be seen from the cross-sectional shape (FIGS. 1 and 2), the storage tank configured as described above relieves the local stress of the storage tank wall caused by the stored material as an external force and also serves as a structural reinforcement. It contributes.
【００１４】[0014]
【実施例２】 また、他の実施例として横断面を角形に形成した貯槽の内部構造を図４および 図５に示す。 ここで、図４は、その横断面図であり、図５は、同じく縦断面図である。 図において、排出スクリュ等は公知の技術になる構成要素として考えればよく 、本考案では特に言及しないので説明を省略する。Second Embodiment As another embodiment, FIGS. 4 and 5 show the internal structure of a storage tank having a rectangular cross section. Here, FIG. 4 is a transverse sectional view thereof, and FIG. 5 is a vertical sectional view thereof. In the drawings, the discharge screw or the like may be considered as a constituent element according to a known technique, and the description thereof is omitted because it is not particularly mentioned in the present invention.
【００１５】 この例におけるガイドリブ（５）は、貯槽内壁（１）の４面のうち、少なくと も対向する２面に複数条設けられれば、所望の効果を有することの実証を得てい る。It has been proved that the guide rib (5) in this example has a desired effect if a plurality of guide ribs (5) are provided on at least two opposite surfaces of the four surfaces of the storage tank inner wall (1).
【００１６】 以上本考案の１実施例について説明したが、貯槽の形状およびガイドリブの形 状，数については、これに限定されることなく、本考案が保護される範囲内にお いて種々の改変を施すことができるものである。Although one embodiment of the present invention has been described above, the shape of the storage tank and the shape and number of the guide ribs are not limited to these, and various modifications are possible within the scope of protection of the present invention. Can be applied.
【００１７】[0017]
本考案は、以上の構成よりなるものであり、これによれば、自重排出式の貯槽 の簡素なガイドリブ構造によって、粉粒体の流動円滑性とブリッジ現象の防止に 優れた効果を奏するので、閉塞の解消が図れる。 The present invention is configured as described above. According to the present invention, the simple guide rib structure of the self-weight discharge type storage tank exerts an excellent effect on the smoothness of flow of powder and granules and the prevention of the bridge phenomenon. The blockage can be eliminated.
【００１８】 また、本考案になる貯槽は、漏斗状の下部構造を有する大形状のホッパー等の 上部貯槽構造として結合・適用でき、しかも、ガイドリブによって、貯槽内壁の 断面形状は、種々に改変可能であるので、貯蔵物に応じた壁面を構成することが でき、ブリッジ現象等を発生し易い処理対象物に対して、広く閉塞解消の効果が 期待できる。Further, the storage tank according to the present invention can be combined and applied as an upper storage structure such as a large hopper having a funnel-shaped lower structure, and the cross-sectional shape of the storage tank inner wall can be variously modified by the guide ribs. Therefore, it is possible to form a wall surface corresponding to the stored material, and it is expected that the blockage can be widely removed with respect to the object to be processed, which easily causes the bridge phenomenon.
