Description

この発明は、土粉砕装置に関する。   The present invention relates to a soil crusher.

従来の土粉砕装置は、たとえば、汚染土壌に吸着剤等を混合して重金属等の汚染物質が外に溶け出さないようにする不溶化処理や、あるいは、土に固化剤等を混合する土壌改良処理を行う混合機に具現化されており、土を粉砕する機能は、ベルトコンベアと、ベルトコンベアの上方に搬送方向に対して直行する回転軸を備えた掻き出しローラと複数の羽根付の粉砕ロータとを備えることで発揮される。   Conventional soil crushing devices are, for example, insolubilization treatment that mixes adsorbents and the like with contaminated soil so that heavy metals and other contaminants do not melt out, or soil improvement treatment that mixes solidifying agents and the like with soil The function of pulverizing the soil is realized by a belt conveyor, a scraping roller provided with a rotating shaft perpendicular to the conveying direction above the belt conveyor, and a pulverizing rotor with a plurality of blades. It is demonstrated by having.

上述した土粉砕装置にあっては、ベルトコンベアで土を投入口側から排出口側まで搬送するとともに、土の投入口であるホッパ付近にて土の上方から固化剤を供給し、土の塊を上記粉砕ロータにて細かく粉砕しつつ、土に固化剤を混合するようになっている（たとえば、特許文献１参照）。
特開２００１−１４０２８１号公報（発明の実施の形態欄，図１） In the soil crusher described above, the soil is transported from the inlet side to the outlet side by the belt conveyor, and the solidifying agent is supplied from above the soil in the vicinity of the hopper, which is the soil inlet, The solidifying agent is mixed with the soil while being finely pulverized with the above pulverizing rotor (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 2001-140281 (Embodiments of the Invention, FIG. 1)

さて、上述のような土粉砕装置は、粉砕ロータが同じ回転速度で回転していることから、回転中における隣り合う粉砕ロータの羽根同士がすれ違う位置がいつも同じとなり、土が該各羽根で掻き混ぜられることなく排出口から排出されてしまう可能性がある。   Now, in the soil crusher as described above, since the crushing rotor rotates at the same rotation speed, the positions where the blades of adjacent crushing rotors pass each other during rotation are always the same, and the soil is scraped by each blade. There is a possibility of being discharged from the outlet without being mixed.

すると、掻き混ぜられなかった土の塊は、細かく粉砕されず、ベルトコンベアでそのままの状態で搬送されてしまい、そのまま排出口から排出される不具合がある。   Then, the lump of soil that has not been stirred is not finely pulverized, but is conveyed as it is on the belt conveyor, and is discharged as it is from the discharge port.

そこで、本発明は、上記不具合を改善するために創案されたものであって、その目的とするところは、土をむらなく粉砕することができる土粉砕装置を提供することである。   Therefore, the present invention has been developed to improve the above-described problems, and an object of the present invention is to provide a soil crushing apparatus that can crush the soil evenly.

上記した目的を達成するために、本発明は、一端側に設けた投入口から投入される土を他端側の排出口へ搬送するベルトコンベアと、ベルトコンベアの上方であって搬送方向に並べて設けられる複数の粉砕ロータとを備えた土粉砕装置において、各粉砕ロータの回転速度が異なるとともに排出口側に位置する粉砕ロータの回転速度は投入口側に位置する粉砕ロータの回転速度より高くなるようにした。   In order to achieve the above-described object, the present invention includes a belt conveyor that conveys soil introduced from an insertion port provided on one end side to a discharge port on the other end side, and is arranged above the belt conveyor in the conveyance direction. In a soil crushing apparatus provided with a plurality of crushing rotors provided, the rotation speed of each crushing rotor is different and the rotation speed of the crushing rotor located on the discharge port side is higher than the rotation speed of the crushing rotor located on the input port side. I did it.

本発明の土粉砕装置にあっては、各粉砕ロータの回転速度が異なるので、隣り合う粉砕ロータ同士の各粉砕羽根のすれ違う位置を周期的に異ならしめることができることができ、これによって土をむらなく粉砕することができる。   In the soil pulverizing apparatus of the present invention, since the rotational speeds of the respective pulverizing rotors are different, the positions at which the respective pulverizing blades of the adjacent pulverizing rotors pass each other can be periodically made different, thereby making the soil uneven. It can be crushed without.

そして、各粉砕ロータの回転速度は、排出口側に行くほど高くなるように設定されており、これにより排出口側の土の移動速度を高めることができ、投入口側の土量より排出口側の土量を少なくなるとともに、ベルトコンベアで土を搬送するので、土が排出口付近に滞留して排出口が詰まってしまうことがない。   The rotational speed of each crushing rotor is set so as to increase toward the discharge port side, so that the movement speed of the soil on the discharge port side can be increased, and the amount of soil on the discharge port side can be increased. Since the amount of soil on the side is reduced and the soil is conveyed by the belt conveyor, the soil does not stay near the discharge port and the discharge port is not clogged.

以下に、図示した実施の形態に基づいて、この発明を説明する。図１は、土粉砕装置の概略図である。図２は、土粉砕装置の平面図である。   The present invention will be described below based on the illustrated embodiment. FIG. 1 is a schematic view of a soil crusher. FIG. 2 is a plan view of the soil crusher.

一実施の形態における土粉砕装置Ｅは、図１および図２に示すように、基本的には、粉砕槽１と、粉砕槽１の底部に設けられるベルトコンベア２と、ベルトコンベア２の搬送方向に並べて設けられる複数の粉砕ロータ３とを備えて構成されている。   As shown in FIG. 1 and FIG. 2, the soil crusher E in one embodiment basically includes a crushing tank 1, a belt conveyor 2 provided at the bottom of the crushing tank 1, and a conveying direction of the belt conveyor 2. And a plurality of grinding rotors 3 arranged side by side.

以下、詳細に説明すると、粉砕槽１は概ね直方体形状に形成され、図１中左端上方には、粉砕槽１の内外を連通する開口部１１が形成され、また、この開口部１１には土の投入を容易とする投入口であるホッパ１２が設けられている。   Hereinafter, the pulverization tank 1 is formed in a substantially rectangular parallelepiped shape, and an opening 11 communicating with the inside and outside of the pulverization tank 1 is formed above the left end in FIG. A hopper 12 is provided as an input port for facilitating the input.

そして、粉砕槽１の他端側は、先細りとなるように、上部が下方に傾斜されて傾斜面１３が形成されるとともに、他端部は開口することにより土を排出する排出口１４が形成されている。   And the other end side of the crushing tank 1 is inclined downward so that the upper part is inclined so that an inclined surface 13 is formed, and the other end is opened to form a discharge port 14 for discharging soil. Has been.

さらに、この粉砕槽１の底部には、ベルトコンベア２が設置されており、このベルトコンベア２は、駆動ロータ２２と、従動ロータ２１と、駆動ロータ２２および従動ロータ２１に巻回される搬送帯２３とを備えて構成され、搬送距離が粉砕槽１の図１中左右長さより長くなるように設定されている。   Further, a belt conveyor 2 is installed at the bottom of the crushing tank 1, and the belt conveyor 2 is a drive rotor 22, a driven rotor 21, and a transport belt wound around the drive rotor 22 and the driven rotor 21. 23, and the conveyance distance is set to be longer than the left and right lengths in FIG.

そして、ベルトコンベア２の図１中右端を排出口１４から突出させてあり、ホッパ１２から投入される土を排出口１４外に搬送することが可能なようになっている。   And the right end in FIG. 1 of the belt conveyor 2 is made to protrude from the discharge port 14, and the soil thrown in from the hopper 12 can be conveyed out of the discharge port 14. FIG.

他方、粉砕ロータ３は、粉砕槽１に回転自在に取り付けた軸３１と、軸３１に取り付けた複数の粉砕羽根３２とを備えて構成され、ベルトコンベア２の搬送方向に並べて複数設けられている。粉砕羽根３２は、図２に示したように、軸３１の軸方向にも複数並べて設けられている。なお、図示したところでは、粉砕ロータ３は４つ設けてあるが、２つ以上であればよい。   On the other hand, the crushing rotor 3 includes a shaft 31 rotatably attached to the crushing tank 1 and a plurality of crushing blades 32 attached to the shaft 31, and a plurality of crushing rotors 3 are provided side by side in the conveying direction of the belt conveyor 2. . As shown in FIG. 2, a plurality of the pulverization blades 32 are provided side by side in the axial direction of the shaft 31. In the figure, four crushing rotors 3 are provided, but two or more crushing rotors may be used.

また、この粉砕ロータ３の外周となる粉砕羽根３２の先端が回転したときに描く円弧とベルトコンベア２の搬送帯２３の上面とが干渉しないように所定の間隔が設けられている。   In addition, a predetermined interval is provided so that the arc drawn when the tip of the grinding blade 32 that is the outer periphery of the grinding rotor 3 rotates and the upper surface of the transport belt 23 of the belt conveyor 2 do not interfere with each other.

なお、粉砕羽根３２の形状は、土を粉砕するのに適していればどのような形状のものとされてもよく、具体的にたとえば、図示したペダル形状のものや、フィン形状のものの使用が可能である。   The shape of the pulverization blade 32 may be any shape as long as it is suitable for pulverizing soil. Specifically, for example, the shape of the pedal shape shown in the figure or the shape of a fin shape may be used. Is possible.

また、軸３１間の距離については、土の粉砕に適当となるように設定されるが、粉砕羽根３２の先端の軌跡が交わるような位置関係で軸３１を配置する場合には、隣り合う軸３１の一方の軸３１に設けられる各粉砕羽根３２が他方の軸３１に設けられる各粉砕羽根３２間に入るように、すなわち、隣り合う軸３１同士の各粉砕羽根３２が入れ子となるようにして、各粉砕羽根３２同士が干渉しないようにすればよい。   Further, the distance between the shafts 31 is set so as to be suitable for the grinding of the soil, but when the shafts 31 are arranged in a positional relationship such that the trajectories of the tips of the grinding blades 32 intersect, 31 so that each crushing blade 32 provided on one shaft 31 enters between each crushing blade 32 provided on the other shaft 31, that is, each crushing blade 32 between adjacent shafts 31 is nested. The crushing blades 32 may be prevented from interfering with each other.

この粉砕ロータ３の各軸３１は、粉砕槽１の側部に設けた油圧モータ等の各駆動源３３によって各々図１中矢印方向に回転駆動されるようになっており、各粉砕ロータ３の回転速度は、各々異なるように設定されるとともに、排出口１４側に位置する粉砕ロータ３の回転速度は投入口側であるホッパ１２側に位置する粉砕ロータ３の回転速度より高くなるように設定されている。   Each shaft 31 of this crushing rotor 3 is rotationally driven in the direction of the arrow in FIG. 1 by each drive source 33 such as a hydraulic motor provided on the side of the crushing tank 1. The rotational speeds are set to be different from each other, and the rotational speed of the grinding rotor 3 located on the discharge port 14 side is set to be higher than the rotational speed of the grinding rotor 3 located on the hopper 12 side which is the charging port side. Has been.

すなわち、ホッパ１２側から排出口１４側に向かうほどに粉砕ロータ３の回転速度が高くなるようになっている。また、ベルトコンベア２の搬送帯２３の搬送速度は、一番低い回転速度で回転するホッパ１２至近の粉砕ロータ３の最外周における周速度、つまり、粉砕羽根３２の先端の周速度より低くなるように設定されている。   That is, the rotational speed of the crushing rotor 3 increases from the hopper 12 side toward the discharge port 14 side. Further, the conveyance speed of the conveyance belt 23 of the belt conveyor 2 is lower than the peripheral speed at the outermost periphery of the crushing rotor 3 near the hopper 12 rotating at the lowest rotation speed, that is, the peripheral speed at the tip of the crushing blade 32. Is set to

さらに、この土粉砕装置Ｅにあっては、上記した粉砕ロータ３の他に、排出口１４の近傍に、回転駆動されるフィーダ４が設けられており、このフィーダ４は、上記複数の粉砕ロータ３で粉砕されてベルトコンベア２で排出口１４に搬送される土の高さを所定の高さに均す均し手段とされている。なお、粉砕槽１の他端部に傾斜面１３を設けており、この傾斜面１３と排出口１４にて、土を一定の高さに均すことが可能であり、上記フィーダ４を設けずこの傾斜面１３と排出口１４のみを均し手段としてもよいが、積極的に回転駆動されるフィーダ４を設けて該フィーダ４で土を均す方が、排出口１４の近傍での土の滞留を防止することができる利点がある。   Further, in the soil crusher E, in addition to the crushing rotor 3 described above, a feeder 4 that is rotationally driven is provided in the vicinity of the discharge port 14, and the feeder 4 includes the plurality of crushing rotors. 3 is a leveling means for leveling the height of the soil crushed at 3 and conveyed to the discharge port 14 by the belt conveyor 2 to a predetermined height. In addition, the inclined surface 13 is provided in the other end part of the crushing tank 1, and it is possible to level the soil to a certain height by the inclined surface 13 and the discharge port 14, and the feeder 4 is not provided. Only the inclined surface 13 and the discharge port 14 may be used as a leveling means. However, it is preferable to provide a feeder 4 that is actively driven to rotate and level the soil with the feeder 4. There is an advantage that retention can be prevented.

また、ベルトコンベア２の排出口１４から突出した部位の上方には、散布手段が設けてある。この場合、具体的には、散布手段は散布ノズル５とされ、この散布ノズル５は、図示しない不溶化剤タンクから供給される汚染物質を吸着する鉱物等を含む不溶化剤を搬送帯２３上の土に散布するようになっている。なお、上記不溶化剤は散布ノズル５で散布しやすいように、スラリー状にしてあるが、粉粒状の不溶化剤を散布する場合には、散布手段を粉粒状の不溶化剤を散布しやすいものにしてもよい。   In addition, a spraying means is provided above the portion protruding from the discharge port 14 of the belt conveyor 2. In this case, specifically, the spraying means is the spray nozzle 5, and the spray nozzle 5 applies an insolubilizer including a mineral adsorbing a contaminant supplied from a not-shown insolubilizer tank to the soil on the transport belt 23. It is supposed to be sprayed on. In addition, although the said insolubilizing agent is made into the slurry form so that it may be easy to spread with the spraying nozzle 5, when spraying a granular insolubilizing agent, a spraying means shall be made easy to spray a granular insolubilizing agent. Also good.

つづいて、上述のように構成された土粉砕装置の動作について説明すると、ホッパ１２内に投入された土は、ベルトコンベア２によって排出口１４に向けて搬送され、その搬送途中で、各粉砕ロータ３によって粉砕される。   Next, the operation of the soil crushing apparatus configured as described above will be described. The soil thrown into the hopper 12 is conveyed toward the discharge port 14 by the belt conveyor 2, and each crushing rotor is in the middle of the conveyance. 3 to grind.

このとき、各粉砕ロータ３の回転速度が異なるので、隣り合う粉砕ロータ３同士の各粉砕羽根３２のすれ違う位置を周期的に異ならしめることができるとともにすれ違い回数を増やすことができ、これによって土をむらなく粉砕することができる。   At this time, since the rotational speeds of the respective grinding rotors 3 are different, the positions at which the grinding blades 32 of the adjacent grinding rotors 3 pass each other can be periodically made different and the number of times of passing can be increased, whereby the soil is removed. It can be pulverized evenly.

このように、この土粉砕装置Ｅにあっては、土をむらなく粉砕可能であるから、その後の不溶化剤等の混合作業も容易となる。   As described above, in the soil pulverizer E, the soil can be pulverized without unevenness, so that the subsequent mixing work of the insolubilizing agent and the like is facilitated.

そして、各粉砕ロータ３の回転速度は、排出口１４側に行くほど高くなるように設定されており、これにより粉砕槽１中の排出口１４側の土の移動速度を高めてホッパ１２側の土量より排出口１４側の土量を少なくできるとともに、ベルトコンベア２で土を搬送するので、土が排出口１４付近に滞留して排出口１４が詰まってしまうことがない。   And the rotational speed of each grinding | pulverization rotor 3 is set so that it may become so high that it goes to the discharge port 14 side, and this raises the movement speed of the soil by the side of the discharge port 14 in the grinding | pulverization tank 1, and makes it the The amount of soil on the discharge port 14 side can be reduced from the amount of soil, and the soil is transported by the belt conveyor 2, so that the soil does not stay near the discharge port 14 and the discharge port 14 is not clogged.

さらに、ベルトコンベア２の搬送速度を一番低速で回転する投入口直下の粉砕ロータ３の周速度より低くしたので、粉砕ロータ３の粉砕羽根３２がベルトコンベア２で搬送される土の移動速度に追いつかずに、該粉砕羽根３２で掻き混ぜられることなしに排出されてしまう土の量を低減でき、これにより、きめ細かに土を粉砕することが可能である。   Further, since the conveying speed of the belt conveyor 2 is set lower than the peripheral speed of the crushing rotor 3 just below the charging port that rotates at the lowest speed, the crushing blades 32 of the crushing rotor 3 are moved to the moving speed of the soil conveyed by the belt conveyor 2. The amount of soil that is discharged without being caught up by the crushing blades 32 without being caught up can be reduced, whereby the soil can be finely crushed.

このようにして、ベルトコンベア２で排出口１４付近まで搬送されてきた土は、上記した各粉砕ロータ３によって細かく粉砕されるが、粉砕されてベルトコンベア２に堆積した土は、排出口１４の近傍に設けた均し手段であるフィーダ４によって土の堆積高さが所定の高さに均されて、排出口１４から排出される。   In this way, the soil conveyed to the vicinity of the discharge port 14 by the belt conveyor 2 is finely pulverized by each of the pulverization rotors 3 described above. The soil accumulation height is leveled to a predetermined height by the feeder 4 which is a leveling means provided in the vicinity, and is discharged from the discharge port 14.

つづき、排出口１４から排出された土は、そのままベルトコンベア２で搬送されて、散布ノズル５から不溶化剤の供給を受ける。そして、上記不溶化剤散布後は、そのまま、土はベルトコンベア２で図１中右方に搬送され、ベルトコンベア２の図１中右端から地面に落下するようになっており、この土の落下が連続的に行われることによって、不溶化剤が土に積層されて土に混合される。   Subsequently, the soil discharged from the discharge port 14 is transported as it is by the belt conveyor 2 and supplied with the insolubilizing agent from the spray nozzle 5. Then, after spraying the insolubilizing agent, the soil is conveyed to the right in FIG. 1 by the belt conveyor 2 and falls to the ground from the right end of the belt conveyor 2 in FIG. 1. By performing continuously, the insolubilizer is laminated | stacked on soil and mixed with soil.

したがって、この土粉砕装置Ｅにあっては、搬送帯２３で移動中の土に不溶化剤を散布することが可能であり、混合ロータ等を設けることなく土と不溶化剤との混合を行うことができる。   Therefore, in this soil crusher E, it is possible to spray the insolubilizing agent on the moving soil in the transport belt 23, and the soil and the insolubilizing agent can be mixed without providing a mixing rotor or the like. it can.

また、特に、均し手段によって土を所定の高さを均すことによって、土に対する不溶化剤の割合を均一にすることができるとともに、土の高さを低く均すようにする場合には、土と不溶化剤をむらなく混合することが可能である。   In addition, in particular, when leveling the soil by a leveling means, the ratio of the insolubilizing agent to the soil can be made uniform, and when the level of the soil is leveled low, It is possible to mix the soil and the insolubilizing agent evenly.

なお、上記したように、傾斜面１３と排出口１４も土の均し機能を備えているので、フィーダ４に異常が生じても、傾斜面１３と排出口１４によって土を均して土と不溶化剤との混合が不能となる事態を回避することができる。   As described above, since the inclined surface 13 and the discharge port 14 also have a soil leveling function, even if an abnormality occurs in the feeder 4, the soil is leveled by the inclined surface 13 and the discharge port 14. A situation in which mixing with the insolubilizer becomes impossible can be avoided.

以上で、本発明の実施の形態についての説明を終えるが、本発明の範囲は図示されまたは説明された詳細そのものには限定されないことは勿論である。   This is the end of the description of the embodiment of the present invention, but the scope of the present invention is of course not limited to the details shown or described.
