Description

【0001】
【発明の属する技術分野】
本発明は、汚染固体物質の回収置に関し、特に、乾式による鉛弾の分離回収方法において、鉛弾を効率的に分離回収することができる汚染固体物質の回収置に関するものである。
【0002】
【従来の技術】
例えば、散弾銃やライフル等の射撃場では、屋外で的撃ちをすることから土壌中に鉛弾が分散される。これらの鉛弾は、従来はそのまま放置されているため、鉛弾そのものが汚染固体物質となって土壌が汚染されるという問題を有していた。
【0003】
このような鉛弾を土砂から分離回収する方法として、湿式では水流等を利用した比重差選別、乾式では風力を利用した比重差選別が考えられる。
湿式による鉛弾の分離回収方法は、高い確率で鉛弾を分別して回収することが可能であるが、鉛汚染された水の処理が必要となり、コストが著しく高くなるという問題を有している。
これに対し、乾式による鉛弾の分離回収方法は、コストやシステム的に有利であるが、風力による分別だけでは湿式のような高い確率で鉛弾を回収することができず、また、粉塵対策も必要であるなどの問題があった。
【0004】
【発明が解決しようとする課題】
本発明は、上記従来の汚染固体物質の回収方法が有する問題点に鑑み、鉛弾が分散した土砂を効率的に分離回収することができる汚染固体物質の回収置を提供することを目的とする。
【0005】
【課題を解決するための手段】
上記目的を達成するため、本発明の汚染固体物質の回収置は、作業者が保持して操作する吸引管により汚染固体物質を吸引する吸引装置と、該吸引装置の下流側に配設され、吸引した汚染固体物質から鉛弾を含む粗粒分を分級する分級装置と、該分級装置の下流側に配設され、分級後の細粒分を集塵する集塵装置とを備えた射撃場の土壌から汚染固体物質である鉛弾が分散した土砂を回収する装置であって、吸引した汚染固体物質から鉛弾を含む粗粒分を分級する分級装置にサイクロンを用い、該サイクロンの下部排出部に回転ヒンジ式ダンパーを配設し、該ダンパーを閉じ方向に付勢してなることを特徴とする。
【0006】
この汚染固体物質の回収装置は、射撃場の土壌から汚染固体物質である鉛弾が分散した土砂を回収する装置であって、作業者が保持して操作する吸引管により汚染固体物質を吸引する吸引装置と、該吸引装置の下流側に配設され、吸引した汚染固体物質から鉛弾を含む粗粒分を分級する分級装置と、該分級装置の下流側に配設され、分級後の細粒分を集塵する集塵装置とを備えることから、鉛弾が分散した土砂を吸引管で吸引して吸引装置により空気搬送し、分級装置で回収することができ、集塵装置の吸い込み量を調整することにより、回収物の粒度調整を可能にするとともに、配管長(搬送長)の違いによる空気量変化(搬送能力変化)にも容易に対応することができ、さらに、搬送ホースから回収バッグヘ直接投入する場合に比べて、搬送効率(能力)が高く、分級も可能で粉塵の飛散も少なくすることができる。
【0007】
そして、吸引した汚染固体物質から鉛弾を含む粗粒分を分級する分級装置にサイクロンを用い、該サイクロンの下部排出部に回転ヒンジ式ダンパーを配設し、該ダンパーを閉じ方向に付勢することにより、集塵装置の吸引力がインジェクターの空気搬送能力を有効に引き出することができる。
【0008】
【発明の実施の形態】
以下、本発明の汚染固体物質の回収置の実施の形態を図面に基づいて説明する。
【0009】
図1〜図2に、本発明の汚染固体物質の回収置の1実施例を示す。
この装置による汚染固体物質の回収方法は、吸引管1により気体と共に汚染固体物質3を吸引し、該吸引した汚染固体物質3から粗粒分3aを分級装置4により分級するとともに、分級後の細粒分3bを集塵装置5により集塵する。
【0010】
また、この回収方法に使用する汚染固体物質の回収装置は、吸引管1により汚染固体物質3を吸引する吸引装置2と、該吸引装置2の下流側に配設され、吸引した汚染固体物質3から粗粒分3aを分級する分級装置4と、該分級装置4の下流側に配設され、分級後の細粒分3bを集塵する集塵装置5とを備えている。
【0011】
吸引装置2は、コンプレッサ6の圧搾空気を利用して吸引を行うインジェクターからなり、吸引側に接続された吸引管1より鉛弾と土等を空気とともに吸引し、排出側に接続された配管(又はホース)を介して分級装置4に空気搬送する。
【0012】
分級装置4はサイクロンからなり、インジェクターにより高速で空気搬送された汚染固体物質3から粗粒分として鉛弾を分級し回収することができる。
サイクロンの下部排出部には、重力式(又はバネ式)の回転ヒンジ式ダンパーが設けてあり、該ダンパーは、常時は閉じている状態で、集塵装置の吸引力がインジェクターの空気搬送能力を有効に引き出している。
また、サイクロンに回収された物質は、所定重量に達したとき、それ自体の重量で、ダンパーを押し下げて、下部に設置したフレコンバッグ等に自動的に回収される。このときも、常に集塵装置によりサイクロン内を負圧に保つことにより、サイクロンから排出するときの粉塵の発生を減じることができる。
なお、サイクロンは、2次空気を導入可能に構成することにより、サイクロンの分級能力を可変にすることができる。
【0013】
集塵装置5は、集塵機51とブロワ52とを備え、鉛弾を除去した後の汚染固体物質3を細粒分(微粒分)として集塵することができる。
この場合、インジェクターの搬送空気量に対して、集塵装置5の吸い込み量を調整加減することにより、分級装置4や集塵装置5での回収物の粒度調整ができるとともに、配管長(搬送長)の違いによる空気量変化(搬送能力変化)にも容易に対応することができる。
【0014】
ところで、散弾銃やライフル等の射撃場では、屋外で的撃ちをすることから土壌中に鉛弾が分散される。これらの鉛弾は、従来はそのまま放置されている。
このような鉛弾が分散した土砂を回収する工事においては、従来、人間の手作業による回収作業が一般に行われているが、特に、土壌中の粒径の小さな鉛弾(直径3mm未満)などの回収は、非常な手間を要する上に取り残しも多いという問題を有している。
【0015】
本実施例の汚染固体物質の回収置は、このような鉛弾が分散した土砂を吸引管1で吸引して吸引装置2により空気搬送し、分級装置4で回収することができる。
この場合、集塵装置5の吸い込み量を調整することにより、回収物の粒度調整を可能にするとともに、配管長(搬送長)の違いによる空気量変化(搬送能力変化)にも容易に対応することができる。
また、この汚染固体物質の回収装置は、搬送ホースから回収バッグヘ直接投入する場合に比べて、搬送効率(能力)が高く、分級も可能で粉塵の飛散も少ない。
さらに、分級装置4と集塵装置5、発電機等の機材を運搬車などに搭載して機動性を向上させれば、広範囲において効率よく回収作業をすることができる。
【0016】
射撃場では、鉛弾そのものが存在していることにより土壌が汚染の基準を超えてしまうが、鉛溶出での土壌のみの汚染は一般的にはあまりみられない。
そのため、集塵装置5の吸い込み量を調整しながら、サイクロンで分級すれば、集塵装置5側には(鉛の比重が大きいため)鉛弾はほとんど移行せず、したがって、集塵装置5により集塵する細粒分に比重の重い汚染固体物質が実質的に含まれない(汚染固体物質の含有量が極めて少ない場合を含む)こととなって、集塵装置5側の回収分はそのまま廃棄する分別処理が可能となり、汚染固体物質の処理コストを低廉にできる。
また、サイクロンで回収されるものは、できるだけ、細粒分が少ないほど、その後の鉛弾分別作業に支障が出ない。例えば、分別機のベルトコンベアに細粒分が付着して搬送効率が悪くなったり、篩の目詰まりが多くなったりすることを防止することができる。
【0017】
以上、本発明の汚染固体物質の回収置の実施例を説明したが、本発明の構成は、上記実施例の記載に限定されるものではなく、その趣旨を逸脱しない範囲において適宜に変更することが可能である。
【0018】
【発明の効果】
本発明の汚染固体物質の回収置によれば、射撃場の土壌から汚染固体物質である鉛弾が分散した土砂を回収する装置であって、作業者が保持して操作する吸引管により汚染固体物質を吸引する吸引装置と、該吸引装置の下流側に配設され、吸引した汚染固体物質から鉛弾を含む粗粒分を分級する分級装置と、該分級装置の下流側に配設され、分級後の細粒分を集塵する集塵装置とを備えることから、鉛弾が分散した土砂を吸引管で吸引して吸引装置により空気搬送し、分級装置で回収することができ、集塵装置の吸い込み量を調整することにより、回収物の粒度調整を可能にするとともに、配管長(搬送長)の違いによる空気量変化(搬送能力変化)にも容易に対応することができ、さらに、搬送ホースから回収バッグヘ直接投入する場合に比べて、搬送効率(能力)が高く、分級も可能で粉塵の飛散も少なくすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a recovery equipment contaminated solid material, in particular, in the lead bullets separation recovery method according to a dry, to a recovery equipment contaminated solid material can be efficiently separated and recovered lead bullets.
[0002]
[Prior art]
For example, in shooting ranges such as shotguns and rifles, lead bullets are dispersed in the soil because they shoot outdoors. Since these lead bullets have been left as they are, they have a problem that the lead bullets themselves become contaminated solid substances and soil is contaminated.
[0003]
As a method for separating and collecting such lead bullets from the earth and sand, a specific gravity difference selection using a water stream or the like is possible in the wet type, and a specific gravity difference selection using the wind force is considered in the dry type.
The method for separating and recovering lead ammunition by wet method is capable of separating and recovering lead ammunition with a high probability, but has the problem that the cost of lead-contaminated water is required and the cost is significantly increased. .
In contrast, dry lead separation and recovery methods are advantageous in terms of cost and system. However, it is not possible to collect lead bullets with a high probability of being wet only by separation by wind power. There were also problems such as being necessary.
[0004]
[Problems to be solved by the invention]
The present invention aims to provide a recovery equipment contaminated solid material the light of the conventional problems recovery process has contaminated solid material, it can be efficiently separated and recovered sediment lead bullets are dispersed To do.
[0005]
[Means for Solving the Problems]
To achieve the above object, the recovery equipment contaminated solid material of the present invention, a suction device for sucking contaminated solid material by suction tube for holding and manipulating the operator, it is disposed downstream of the suction device , Shooting equipped with a classification device for classifying coarse particles containing lead bullets from the sucked contaminated solid material, and a dust collecting device arranged downstream of the classification device for collecting fine particles after classification A device that collects soil and sand in which lead bullets that are contaminated solid substances are dispersed from the soil in the field, and uses a cyclone to classify coarse particles containing lead bullets from the sucked contaminated solid materials, and the lower part of the cyclone A rotary hinge type damper is disposed in the discharge portion, and the damper is biased in the closing direction.
[0006]
This contaminated solid material recovery device is a device that recovers soil and sand in which lead bullets, which are contaminated solid materials, are dispersed from the shooting ground soil, and sucks the contaminated solid materials by a suction pipe held and operated by an operator. A suction device, a classification device arranged on the downstream side of the suction device, for classifying coarse particles containing lead bullets from the sucked contaminated solid substance, and a classification device arranged on the downstream side of the classification device, Since it is equipped with a dust collector that collects particles, it is possible to suck the earth and sand in which lead bullets are dispersed with a suction pipe, carry it by air with a suction device, and collect it with a classification device. By adjusting, it is possible to adjust the particle size of the recovered material, and easily cope with air volume changes (conveyance capacity changes) due to differences in pipe length (conveyance length). Compared to putting it directly into the bag, Higher feed efficiency (capacity) of classification can also be less scattering of dust can be.
[0007]
Then, a cyclone is used in a classifier for classifying coarse particles containing lead bullets from the sucked contaminated solid substance, and a rotary hinge type damper is disposed at the lower discharge portion of the cyclone, and the damper is biased in the closing direction. Thus, the suction force of the dust collector can effectively draw out the air conveying capability of the injector.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the recovery equipment contaminated solid material of the present invention with reference to the accompanying drawings.
[0009]
In FIGS. 1-2, showing one embodiment of the recovery equipment contaminated solid material of the present invention.
Method for recovering contaminated solid materials by this apparatus, a contaminated solid material 3 by suction with air by the suction tube 1, as well as classified by the classification unit 4 a coarse fraction 3a from the contaminated solid material 3 that the suction, after classification fine The particle fraction 3 b is collected by the dust collector 5.
[0010]
In addition, the contaminated solid substance recovery device used in this recovery method includes a suction device 2 that sucks the contaminated solid substance 3 through the suction tube 1, and a suctioned contaminated solid substance 3 that is disposed downstream of the suction device 2. Are provided with a classification device 4 for classifying the coarse particle fraction 3a, and a dust collector 5 disposed downstream of the classification device 4 for collecting the fine particle fraction 3b after classification.
[0011]
The suction device 2 is composed of an injector that performs suction using the compressed air of the compressor 6, and sucks lead bullets and soil together with air from the suction pipe 1 connected to the suction side, and is connected to the discharge side (pipe ( Alternatively, the air is conveyed to the classifier 4 via a hose).
[0012]
The classifying device 4 is made of a cyclone, and can classify and recover lead bullets as coarse particles from the contaminated solid material 3 which is air conveyed at high speed by an injector.
A gravity-type (or spring-type) rotary hinge damper is provided at the lower discharge part of the cyclone, and the damper is normally closed, and the suction force of the dust collector improves the air conveyance capability of the injector. Pull out effectively.
In addition, when the substance collected in the cyclone reaches a predetermined weight, the damper is pushed down by its own weight and automatically collected in a flexible container bag or the like installed in the lower part. Also at this time, generation of dust when discharging from the cyclone can be reduced by always maintaining a negative pressure in the cyclone by the dust collector.
It should be noted that the cyclone classification capability can be made variable by configuring the cyclone so that secondary air can be introduced.
[0013]
The dust collector 5 includes a dust collector 51 and a blower 52, and can collect the contaminated solid material 3 after removing the lead bullets as fine particles (fine particles).
In this case, by adjusting the amount of suction of the dust collector 5 with respect to the amount of air transported by the injector, the particle size of the recovered material in the classifier 4 and the dust collector 5 can be adjusted, and the pipe length (conveyance length) ) Can easily cope with changes in the air amount (changes in conveying capacity).
[0014]
By the way, in shooting ranges such as shotguns and rifles, lead bullets are dispersed in the soil because they shoot outdoors. These lead bullets are conventionally left as they are.
In such a construction for collecting earth and sand in which lead bullets are dispersed, collection work by human manual work has been generally performed. In particular, lead bullets with a small particle diameter in the soil (less than 3 mm in diameter), etc. However, there is a problem that a large amount of waste remains.
[0015]
Recovery equipment contaminated solid material of the present embodiment can be such lead bullets are air conveyed by the suction device 2 by suction dispersed sediment in the suction pipe 1, is recovered by classification device 4.
In this case, by adjusting the suction amount of the dust collecting device 5, it is possible to adjust the particle size of the collected material, and easily cope with the air amount change (conveyance capacity change) due to the difference in the pipe length (conveyance length). be able to.
Further, this contaminated solid substance recovery device has higher transfer efficiency (capacity), classification, and less dust scattering compared to the case where the transfer hose is directly fed into the recovery bag.
Furthermore, if equipment such as the classifying device 4, the dust collecting device 5, and the generator is mounted on a transport vehicle or the like to improve mobility, the collection work can be efficiently performed in a wide range.
[0016]
At the shooting range, the presence of the lead bullet itself causes the soil to exceed the contamination standards, but the contamination of only the soil due to lead elution is generally not so common.
Therefore, if the cyclone classification is performed while adjusting the suction amount of the dust collector 5, lead bullets hardly move to the dust collector 5 side (because of the large specific gravity of lead). The fine particulate matter to be collected is substantially free of contaminated solid substances with a high specific gravity (including the case where the content of contaminated solid substances is extremely low), and the collected part on the dust collector 5 side is discarded as it is. Therefore, it is possible to reduce the processing cost of the contaminated solid material.
Moreover, the thing collected with a cyclone has as little fine grain as possible, so that it does not interfere with the subsequent lead bullet separation work. For example, it is possible to prevent the fine particles from adhering to the belt conveyor of the sorting machine to deteriorate the conveyance efficiency or increase the clogging of the sieve.
[0017]
Having described the embodiments of the recovery equipment contaminated solid material of the present invention, the configuration of the present invention is not intended to be limited to the description of the above embodiment is changed appropriately within a scope not departing from its gist It is possible.
[0018]
【The invention's effect】
According to the recovery equipment contaminated solid material of the present invention, there is provided an apparatus for recovering sand which lead bullets is contamination solid material is dispersed from the shooting range of soil, contaminated with suction tube for holding and manipulating the worker A suction device that sucks solid substances, a classification device that is disposed downstream of the suction device, classifies coarse particles containing lead bullets from the sucked contaminated solid material, and is disposed downstream of the classification device. And a dust collector that collects the fine particles after classification, so that the earth and sand in which lead bullets are dispersed can be sucked with a suction pipe, air-fed by the suction device, and collected by the classifier. By adjusting the suction amount of the dust device, it is possible to adjust the particle size of the recovered material, and it can easily cope with changes in the air amount (change in transfer capacity) due to differences in pipe length (transfer length). When directly feeding from the transport hose to the collection bag Compared to, transport efficiency (capacity) is high, classification may also be reduced that scattering also possible dust.
[0019]
Then, a cyclone is used in a classifier for classifying coarse particles containing lead bullets from the sucked contaminated solid substance, and a rotary hinge type damper is disposed at the lower discharge portion of the cyclone, and the damper is biased in the closing direction. Thus, the suction force of the dust collector can effectively draw out the air conveying capability of the injector.
