Description

本発明は、飛灰、セメント、化成品などの粉状、粒状若しくは砂礫状の原材料、製品、又は製品の製造工程に於ける中間品、副産物、廃棄物などの分別対象物の分別に係り、特定元素の含有レベルに応じて分別対象物を分別する分別装置、分別方法及び資材の製造方法に関する。   The present invention relates to separation of powdered, granular or gravel-like raw materials such as fly ash, cement, and chemical products, products, or separation objects such as intermediate products, by-products, and waste in the manufacturing process of the products, The present invention relates to a sorting device, a sorting method, and a material manufacturing method for sorting a sorting object according to the content level of a specific element.

近年、廃棄物の発生量増加に伴って、最終処分場の残存容量の減少が問題化しており、原材料の効率的な利用やリサイクルの推進により、資源の消費を抑制し、環境への負荷の低減を図ることが求められている。しかし、原材料の効率的利用やリサイクルの推進を図るに当たっては、原材料や廃棄物等の中に含有されている特定元素が問題となる。そのため、原材料や廃棄物については含有有害成分に対する規制が行われており、この規制値に合致したものを使用することが求められ、また適切な処理を実施して十分な品質管理が為された製品を出荷することが必要とされる。例えば、セメントを製造する分野では、飛灰、汚泥、汚染土壌などの各種廃棄物がリサイクルを推進するためにセメントに混合されており、そのためこれらの各種廃棄物に含まれている特定元素の含有量を予め測定して分別し、適切、安全なものを使用することが求められる。   In recent years, with the increase in the amount of waste generated, the decrease in the remaining capacity of the final disposal site has become a problem, and the efficient use of raw materials and the promotion of recycling have suppressed the consumption of resources and reduced the burden on the environment. There is a demand for reduction. However, specific elements contained in raw materials, wastes, etc. become a problem when promoting efficient use and recycling of raw materials. Therefore, raw materials and waste are regulated with respect to harmful components, and it is required to use those that meet these regulatory values, and adequate quality control has been performed through appropriate processing. It is necessary to ship the product. For example, in the field of manufacturing cement, various types of waste such as fly ash, sludge, and contaminated soil are mixed with cement to promote recycling. Therefore, the contents of specific elements contained in these various types of waste are included. It is required to measure and sort the amount in advance and use an appropriate and safe one.

また、ガラス製品のリサイクル例としては、廃蛍光灯の両端をカットしてガラス管部分と口金部分とに分け、ガラス管部分を破砕して高品位のガラスカレットとして、蛍光灯内に封入されている水銀を回収して高純度の水銀として、また口金部分はアルミや鉄等の地金として再生し、さらに異物の多いガラスカレットはセメント原料としてリサイクルしている。このため、ガラスカレットや金属或いは重金属を適切に分別し、有効な再生資源として利用できるようにすることが求められる。   As an example of glass product recycling, cut both ends of a waste fluorescent lamp to separate it into a glass tube part and a base part. The glass tube part is crushed and sealed in a fluorescent lamp as a high-quality glass cullet. Mercury is recovered and recycled as high-purity mercury, the base part is recycled as ingots such as aluminum and iron, and glass cullet with many foreign substances is recycled as a raw material for cement. For this reason, it is required to appropriately sort glass cullet, metal, or heavy metal so that it can be used as an effective recycled resource.

前述の如く原材料の有効利用や廃棄物などのリサイクルを推進する上では、原材料や廃棄物などの適切な分別が行われないと、製品に有害物質や妨害物質が不純物として混入し、製品の工程管理や品質管理が難しくなってしまうため、原材料や廃棄物などの適切な分別を行うことが極めて重要となる。   As mentioned above, in promoting the effective use of raw materials and recycling of wastes, if proper separation of raw materials and wastes is not performed, harmful substances and interfering substances are mixed as impurities into the product, and the product process Since management and quality control become difficult, it is extremely important to properly separate raw materials and waste.

原材料や廃棄物を適切に分別する装置としては、例えば特許文献1、2の蛍光X線を用いた装置が知られている。特許文献1には、分別の対象となる廃回路基板を常に一定速度で移動させながら、蛍光X線分析により特定元素の含有の有無を検知し、その検知結果に応じて廃棄物を分別する装置が開示されている。   As an apparatus for appropriately separating raw materials and waste, for example, apparatuses using fluorescent X-rays disclosed in Patent Documents 1 and 2 are known. Patent Document 1 discloses an apparatus that detects whether or not a specific element is contained by fluorescent X-ray analysis while always moving a waste circuit board to be sorted at a constant speed, and sorts waste according to the detection result. Is disclosed.

また、特許文献2には、空気中に於いても蛍光X線による分析を可能にするため、静止状態の部材と蛍光X線検出装置との間隔を検出可能な範囲まで短くして検出感度を高くする識別装置と、より検出感度を高くするために不活性ガス中におけるX線透過率が空気中に於けるそれよりも大きいことを利用し、検査室を不活性ガスであるヘリウム雰囲気として部材を蛍光X線分析する識別装置とが開示されている。   Further, in Patent Document 2, in order to enable analysis with fluorescent X-rays even in the air, the detection sensitivity is increased by shortening the distance between the stationary member and the fluorescent X-ray detection device to a detectable range. Utilizing the identification device to be increased and the fact that the X-ray transmittance in the inert gas is higher than that in the air in order to further increase the detection sensitivity, the inspection chamber is made into a helium atmosphere that is an inert gas. And an identification device for X-ray fluorescence analysis.

ところで、特許文献1の分別装置は、分別の対象となる廃回路基板が蛍光X線分析中においても常に一定速度で移動し、しかも蛍光X線検出装置と非接触の状態で分別の対象となる廃回路基板から特定元素の含有の有無を検知することを特徴とするものである。この場合、廃回路基板と蛍光X線検出装置とに離間距離があることにより、蛍光X線の強度が減衰してしまうため、特定元素の含有の有無については判定できたとしても、特定元素の含有レベルまでを判定することは困難である。   By the way, the separation device of Patent Document 1 always moves at a constant speed even during waste X-ray analysis of a waste circuit board to be separated, and is a separation target in a non-contact state with the X-ray fluorescence detection device. It is characterized by detecting the presence or absence of a specific element from a waste circuit board. In this case, since there is a separation distance between the waste circuit board and the fluorescent X-ray detection device, the intensity of the fluorescent X-rays is attenuated. Therefore, even if the presence or absence of the specific element can be determined, It is difficult to determine the content level.

また、特許文献2の識別装置では、識別対象の部材を静止状態にして蛍光X線の検出を行っているもののが、特許文献1と同様に識別対象の部材と蛍光X線検出装置とが非接触の状態で検出を行っているため、たとえ検査室をヘリウム雰囲気としても蛍光X線の強度が減衰し、特定元素の含有レベルまでを判定することは困難である。   Further, in the identification device of Patent Document 2, although the member to be identified is stationary and the fluorescent X-ray is detected, the member to be identified and the fluorescent X-ray detection device are not similar to those of Patent Document 1. Since detection is performed in a contact state, the intensity of fluorescent X-rays is attenuated even if the examination room is in a helium atmosphere, and it is difficult to determine the content level of a specific element.

By the classification, a material having a specific element content level of a predetermined level or lower or a predetermined level or higher can be used as a material.

尚、蛍光X線計測部は、分別装置に1台のみ用いるものとしてもよいが、搬送部の搬送経路に搬送方向に沿って複数台を配列して設置する構成、或いは水平な搬送方向と直角方向に複数台を配列して設置する構成とすると好適であり、前記構成により、一度に蛍光X線を計測できる分別対象物の分量が増え、特定元素の含有レベルの計測を短時間で行える、或いは広い範囲の計測を行うことができる。更に、複数台の蛍光X線計測部の計測結果の平均値を用いること等により、特定元素の含有レベルの判定精度をより高めることも可能となる。また、分別対象物によっては、異なる機種の蛍光X線計測部を複数台配列して設置する構成としてもよい。前記異種の携帯型蛍光X線計測装置を複数台設け、各携帯型蛍光X線計測装置の所定の蛍光X線の計測結果から所定の特定元素の含有レベルを判定部で判定することにより、異種の特定元素の含有レベルをほぼ同時に判定することができ、例えば判定部が何れの特定元素の含有レベルも設定されている規制値以下であるもののみを資材として分別することが可能となる。   In addition, although only one fluorescent X-ray measuring unit may be used for the sorting device, a configuration in which a plurality of units are arranged along the transport direction in the transport path of the transport unit, or perpendicular to the horizontal transport direction. It is preferable to have a configuration in which a plurality of units are arranged and installed in the direction. With the above configuration, the amount of the separation target that can measure fluorescent X-rays at a time increases, and the content level of a specific element can be measured in a short time.

It is possible to sort the objects to be sorted according to the content level of the specific element. Then, the content level of a specific element can be determined in a much finer unit than the method of determining the content level of a specific element in a separation object by sampling a very small amount from a huge amount of the separation object. It is possible to reliably separate elements whose element content level is below the regulation value / standard value, improve the quality control level and ensure product safety, and use and recycle resources efficiently.

Therefore, the separation target to be conveyed and the determination result of the content level of the specific element can be matched, and the separation target can be efficiently separated, and the efficiency of the process management in the manufacturing facility, the recycling facility, etc. can be improved. . Moreover, since it can be comprised with a simple installation, it is excellent in economical efficiency.

The grizzly 1 is provided by supporting a plurality of bars 1a arranged side by side on a hopper 2, and by adjusting the interval between the bars 1a and 1a serving as a sieve, the particle size in the separation object S is more than 50 mm. Coarse particles exceeding the particle diameter are kept on the bar 1a so as not to fall onto the hopper 2, and only a separation object having a predetermined particle diameter or less, such as a particle diameter of 50 mm or less, can be put into the hopper 2. Furthermore, the grizzly 1 in the present embodiment is provided with a vibro motor not shown in the figure, and the vibro motor vibrates the grizzly 1 as necessary so that the separation object S having a predetermined particle size or less is the bar 1a. It is the structure which can facilitate passing between 1a. Further, when discharging the coarse particles retained on the bar 1a, by supporting the bar 1a in an inclined manner, it is discharged to a transport path to a process for performing processing corresponding to the coarse particles. Yes.

ホッパー2は、グリズリー1で粗粒分が除去され、グリズリー1を通過して投入される所定粒径以下の分別対象物Sを一時貯留し、前記所定粒径以下の分別対象物Sの所定量を安定してベルトコンベア3に供給する。また、ベルトコンベア3は、ホッパー2から所定量ずつ排出される分別対象物Sを所定量ずつ搬送し、設定される一定速度で分別対象物Sを搬送する。   The hopper 2 removes coarse particles by the grizzly 1, temporarily stores the separation target S having a predetermined particle size or less that is introduced through the grizzly 1, and the predetermined amount of the separation target S having the predetermined particle size or less. Is stably supplied to the belt conveyor 3. Further, the belt conveyor 3 conveys the separation object S discharged from the hopper 2 by a predetermined amount by a predetermined amount, and conveys the separation object S at a set constant speed.

ローラー4は、分別対象物Sの搬送経路に於ける蛍光X線計測部5の上流側に設けられ、ベルトコンベア3で搬送される分別対象物Sの表面近傍領域を押圧しながら回転し、分別対象物Sの表面を平滑にすると共に、分別対象物Sの少なくとも上層の密度或いは充填度を高められるようになっている。ローラー4は、分別対象物Sの含水状態や性状等に応じて、十分な平滑さ、充填度を得ると共に、ベルトコンベア3上で過度に押圧されて付着することを防止する必要があるため、図に省略した昇降機構で昇降し、分別対象物Sに加える圧力を増加或いは減少可能になっている。また、ローラー4の支持部には光電センサー等のセンサー4aが設置されており、センサー4aでローラー4の直下或いはその近傍位置に於ける分別対象物までの距離を計測し、その計測距離を制御部7に出力する。制御部7は、その記憶部に制御プログラムと、分別対象物Sが無い場合の距離と、ベルトコンベア3の速度と対応して設定されている搬送時間とを記憶しており、その演算処理部は前記制御プログラムに従い、前記センサー4aから入力される計測距離と前記分別対象物Sが無い場合の距離を対比して、前記計測距離が前記分別対象物Sが無い場合の距離を超えている場合に、前記設定されている搬送時間だけベルトコンベア3の搬送を継続して停止し、前記センサー4aで検知した分別対象物Sの部分を蛍光X線計測部5の直下或いはその近傍に位置させるようにベルトコンベア3を制御し、更に、後述する蛍光X線計測部5のセンサー5bが作動するように制御する。また、前記搬送時間で制御する構成に代え、例えばローラー4にローラー4の回転数を検知するセンサーを設け、前記計測距離が前記分別対象物Sが無い場合の距離を超えた場合に、前記距離を超えた時点から前記センサーでローラーの回転数を計測し、前記回転数を制御部7に出力し、制御部7は記憶している設定回転数と前記計測回転数とを対比し、前記計測回転数が前記設定回転数に到達した時点でベルトコンベア3の搬送を停止し、前記センサー4aで検知した分別対象物Sの部分を蛍光X線計測部5の直下或いはその近傍に位置させるようにベルトコンベア3を制御する構成とすることも可能である。   The roller 4 is provided on the upstream side of the fluorescent X-ray measurement unit 5 in the conveyance path of the separation target S, and rotates while pressing a region in the vicinity of the surface of the separation target S conveyed by the belt conveyor 3. While smoothing the surface of the target object S, the density or the filling degree of at least the upper layer of the separation target object S can be increased. Since the roller 4 needs to obtain sufficient smoothness and filling degree according to the water content and properties of the separation target S, and it is necessary to prevent the roller 4 from being excessively pressed and adhered on the belt conveyor 3, The pressure applied to the separation target S can be increased or decreased by the lifting mechanism not shown in the figure. In addition, a sensor 4a such as a photoelectric sensor is installed on the support portion of the roller 4, and the sensor 4a measures the distance to the separation object immediately below or near the roller 4 and controls the measurement distance.

Further, the belt conveyor 3 is controlled, and further, the sensor 5b of the fluorescent X-ray measuring unit 5 described later is controlled to operate. Moreover, it replaces with the structure controlled by the said conveyance time, for example, the sensor which detects the rotation speed of the roller 4 is provided in the roller 4, and when the said measurement distance exceeds the distance when the said separation target S does not exist, the said distance The rotation speed of the roller is measured by the sensor from the point of time exceeding the value, and the rotation speed is output to the control unit 7. The control unit 7 compares the stored set rotation speed with the measured rotation speed, and the measurement When the rotation speed reaches the set rotation speed, the conveyance of the belt conveyor 3 is stopped, and the portion of the separation target S detected by the sensor 4a is positioned directly below or in the vicinity of the fluorescent X-ray measurement section 5. A configuration in which the belt conveyor 3 is controlled is also possible.

蛍光X線計測部5は、ベルトコンベア3上でローラー4により層調整された分別対象物Sの表面に計測窓5aを当接し、内部のX線照射部から計測窓5aを介してX線を照射し、前記X線照射によって発生する蛍光X線を計測窓5aを介して内部の蛍光X線計測部で取得して蛍光X線を計測するものである。蛍光X線計測部5は、エアシリンダ或いは油圧シリンダ等の駆動部5cによって昇降し、必要に応じて水平方向に動く等して、分別対象物Sの表面に計測窓5aを当接し、又、前記当接状態から計測窓5aと離間して復帰するように動作可能である。蛍光X線計測部5には光電センサー等のセンサー5bが設置されており、センサー5bで蛍光X線計測部5の計測窓5aの直下或いはその近傍位置に於ける分別対象物Sまでの距離を計測し、その計測距離を制御部7に出力する。制御部7は、その記憶部に制御プログラムを記憶し、その演算処理部は前記制御プログラムに従い、前記センサー5bから入力される計測距離だけ蛍光X線計測部5を下降させ、計測窓5aを分別対象物Sの表面に当接し、蛍光X線計測部5を作動させる。蛍光X線計測部5は前記作動指令に従い、計測窓5aから分別対象物SにX線を照射し、蛍光X線を計測窓5aから取得して蛍光X線の計測値を取得し、蛍光X線の計測値を判定部8に出力する。そして、前記蛍光X線の計測の完了に伴い、制御部7は蛍光X線計測部5を上昇させ、元の位置に復帰させ、後述する清掃化部6を作動させると共に、ベルトコンベア3を作動させ、分別対象物Sをベルトコンベア3の搬送方向の端部まで搬送する。   The fluorescent X-ray measurement unit 5 abuts the measurement window 5a on the surface of the separation target S layer-adjusted by the roller 4 on the belt conveyor 3, and emits X-rays from the internal X-ray irradiation unit through the measurement window 5a. The fluorescent X-rays generated by the X-ray irradiation are acquired by an internal fluorescent X-ray measuring unit through the measurement window 5a, and the fluorescent X-rays are measured. The fluorescent X-ray measurement unit 5 is moved up and down by a drive unit 5c such as an air cylinder or a hydraulic cylinder, moved in a horizontal direction as necessary, and the measurement window 5a is brought into contact with the surface of the separation target S, It is possible to operate so as to return from the contact state away from the measurement window 5a. The fluorescent X-ray measurement unit 5 is provided with a sensor 5b such as a photoelectric sensor. The sensor 5b determines the distance to the separation object S directly below or near the measurement window 5a of the fluorescent X-ray measurement unit 5.

The control unit 7 stores a control program in the storage unit, and the arithmetic processing unit lowers the fluorescent X-ray measurement unit 5 by the measurement distance input from the sensor 5b according to the control program, and separates the measurement window 5a. Abutting on the surface of the object S, the fluorescent X-ray measurement unit 5 is operated. In accordance with the operation command, the fluorescent X-ray measurement unit 5 irradiates the separation target S with X-rays from the measurement window 5a, acquires fluorescent X-rays from the measurement window 5a, acquires fluorescent X-ray measurement values, and acquires fluorescent X-rays. The measured value of the line is output to the determination unit 8. Then, with the completion of the measurement of the fluorescent X-rays, the control unit 7 raises the fluorescent X-ray measurement unit 5 to return to the original position, operates the cleaning unit 6 described later, and operates the belt conveyor 3. Then, the separation object S is transported to the end of the belt conveyor 3 in the transport direction.

清掃化部6は、蛍光X線計測部5の計測窓5aの分別対象物Sの表面との接触により計測窓5aに付着した分別対象物Sを除去し、計測窓5aを清浄化するものである。制御部7の演算処理部は記憶部に記憶する制御プログラムに従い、清掃化部6を作動させ、所定の清浄化動作を完了した後に停止するようになっている。清掃化部6は、例えば噴射口から圧縮空気を噴射して計測窓5aに付着した分別対象物Sを除去するエア噴射部、吸引口から減圧吸引して計測窓5aに付着した分別対象物Sを除去する吸引部、若しくは噴射口から水を噴射して計測窓5aに付着した分別対象物Sを除去する水噴射部、若しくは計測窓5aに付着した分別対象物にマイナスの静電気を帯びさせてプラスの電極で集塵する電気集塵部、若しくは計測窓5aをワイパー、ブラシ等で掃き取って計測窓5aに付着した分別対象物Sを除去する掃取部、若しくは計測窓5aを布、スポンジ等で拭い取って計測窓5aに付着した分別対象物Sを除去する払拭部、若しくはこれらの適宜の組み合わせ等とすることが可能である。分別対象物Sが比較的乾燥したものである場合には、例えばエア噴射部のみで十分であるが、含水状態の分別対象物の場合には、例えば掃取部、払拭部と水噴射部とエア噴射部とを設け、計測窓5aに付着した分別対象物を掃取部のワイパーやブラシ、払拭部の布やスポンジで直接接触するようにして除去し、水噴射部で計測窓5aを洗浄し、その後、エア噴射部で計測窓5aに付着した水を圧縮空気で吹き飛ばすようにすると好適である。前記清浄化部により、計測窓5aを常に清潔に保ち、長期且つ正確に蛍光X線の計測や特定元素の含有レベルの判定を行うことができる。尚、清掃化部6による分別対象物Sの除去は、計測窓5aが分別対象物Sの表面から離れ、蛍光X線計測部5が元の位置に復帰する前の適宜の位置で行うことが可能である。   The cleaning unit 6 removes the separation target S attached to the measurement window 5a by contact with the surface of the separation target S of the measurement window 5a of the fluorescent X-ray measurement unit 5, and cleans the measurement window 5a. is there. The arithmetic processing unit of the control unit 7 operates the cleaning unit 6 according to a control program stored in the storage unit, and stops after completing a predetermined cleaning operation. For example, the cleaning unit 6 ejects compressed air from the injection port to remove the separation target S attached to the measurement window 5a, and the separation target S attached to the measurement window 5a by vacuum suction from the suction port. The suction part that removes water, or the water jet part that ejects water from the injection port and removes the separation object S attached to the measurement window 5a, or the separation object attached to the measurement window 5a is charged with negative static electricity. Electric dust collecting part that collects dust with a positive electrode, or sweeping part that removes the separation object S attached to the measuring window 5a by sweeping the measuring window 5a with a wiper, brush, etc., or a measuring window 5a that is made of cloth, sponge It is possible to use a wiping unit that removes the separation target S that has been wiped off and attached to the measurement window 5a, or an appropriate combination thereof. When the separation target S is relatively dry, for example, only the air injection unit is sufficient. However, in the case of a water-containing separation target, for example, a sweeping unit, a wiping unit, a water injection unit, An air injection unit is provided, and the separation object attached to the measurement window 5a is removed by making direct contact with the wiper or brush of the sweeping unit or the cloth or sponge of the wiping unit, and the measurement window 5a is washed by the water injection unit After that, it is preferable that the water adhering to the measurement window 5a is blown off with compressed air by the air injection unit. By the said cleaning part, the measurement window 5a can always be kept clean and a fluorescent X-ray measurement and the determination of the content level of a specific element can be performed accurately over a long period of time. The removal of the separation target S by the cleaning unit 6 may be performed at an appropriate position before the measurement window 5a moves away from the surface of the separation target S and the fluorescent X-ray measurement unit 5 returns to the original position. Is possible.

判定部8は、蛍光X線計測部5から入力される計測値を解析し、分別対象物Sの特定元素の含有レベルを判定するものである。判定部8は、その記憶部に制御プログラムと、蛍光X線の計測値に対応する特定元素の含有レベルのテーブルと、規制値等に対応する特定元素の含有レベルの閾値とを記憶し、その演算処理部は前記制御プログラムに従い、蛍光X線計測部5から入力される計測値に対応する特定元素の含有レベルを前記テーブルから認識し、前記認識した含有レベルを前記閾値と対比し、前記閾値未満の場合に再利用等の経路にするように分別部9を制御し、前記閾値超の場合には廃棄或いは浄化処理等の経路にするように分別部9を制御する。また、判定部8は、その記憶部に制御プログラムと、特定元素の含有レベルに対応し且つ規制値等に対応する閾値とを記憶し、その演算処理部が前記制御プログラムに従い、蛍光X線計測部5から入力される計測値と前記閾値とを対比し、特定元素の含有レベルの判定結果として前記対比結果を取得し、前記閾値未満の場合に再利用等の経路にするように分別部9を制御し、前記閾値超の場合には廃棄或いは浄化処理等の経路にするように分別部9を制御してもよい。尚、判定部8と制御部7は異なるハードウェアで構成しても、同一のハードウェアで構成してもよい。   The determination unit 8 analyzes the measurement value input from the fluorescent X-ray measurement unit 5 and determines the content level of the specific element in the separation target S. The determination unit 8 stores a control program, a table of content levels of specific elements corresponding to measured values of fluorescent X-rays, and a threshold value of content levels of specific elements corresponding to regulation values, etc. in the storage unit, The arithmetic processing unit recognizes the content level of the specific element corresponding to the measurement value input from the fluorescent X-ray measurement unit 5 from the table according to the control program, and compares the recognized content level with the threshold value. If it is less than the threshold value, the sorting unit 9 is controlled so as to make a route for reuse, and if it exceeds the threshold value, the sorting unit 9 is controlled so as to make a route for disposal or purification processing. In addition, the determination unit 8 stores a control program and a threshold value corresponding to the content level of the specific element and corresponding to the regulation value in the storage unit, and the arithmetic processing unit performs fluorescent X-ray measurement according to the control program. The classification unit 9 compares the measurement value input from the unit 5 with the threshold value, acquires the comparison result as the determination result of the content level of the specific element, and makes a path for reuse or the like when the level is less than the threshold value. If the threshold value is exceeded, the separation unit 9 may be controlled so as to use a path for disposal or purification. The determination unit 8 and the control unit 7 may be configured by different hardware or the same hardware.

分別部9は、判定部8の制御に応じて分別対象物Sを分別し、判定部8の判定結果に応じて分別対象物Sの仕分経路を切り換えて分別対象物Sを分別するものであり、本実施形態の分別部9は横軸を中心に傾動し、傾斜角度が可変なガイド板としている。前記ガイド板は、ベルトコンベア3から排出される分別対象物Sと接触し、判定部8の制御に応じて傾斜角度が変更されて、前記排出される分別対象物Sの落下方向を変化させ、ベルトコンベアで各々構成される仕分経路10又は11に分別対象物Sを仕分ける。尚、仕分経路は、異なる方向に分別対象物Sを搬送可能なのものであれば適宜であり、前記2つのベルトコンベアの他、正逆転ベルトコンベア、或いは2つ若しくは複数の移動式コンテナ等とすることが可能である。   The separation unit 9 separates the separation target S according to the control of the determination unit 8 and switches the sorting path of the separation target S according to the determination result of the determination unit 8 to separate the separation target S. The separation unit 9 of this embodiment is a guide plate that tilts about the horizontal axis and has a variable tilt angle. The guide plate comes into contact with the separation object S discharged from the belt conveyor 3, the inclination angle is changed according to the control of the determination unit 8, and the falling direction of the discharged separation object S is changed, Sorting objects S are sorted into sorting paths 10 or 11 each constituted by a belt conveyor. The sorting path is appropriate as long as the sorting object S can be conveyed in different directions, and in addition to the two belt conveyors, a forward / reverse belt conveyor, or two or a plurality of movable containers, etc. It is possible.

尚、分別装置の各構成部には必要に応じてセンサーを設け、前記センサーの検知情報を制御部7等で解析し、前記解析結果に応じて制御部7等が、前記センサーが設置されている構成部或いは前記センサーの検知に応じて動作させることが必要な構成部を動作させる構成とすることが好ましい。また、蛍光X線計測部5の一回の計測によって、前記計測が行われた箇所の分別対象物S毎に分別する構成の他に、ベルトコンベア3上で所定間隔をおいて蛍光X線計測部5による複数回の計測を行い、判定部8が前記複数階の計測値の平均値を取得し、前記平均値と閾値とを対比した判定結果により、前記計測箇所全体を分別することも可能である。また、例えば計測窓5aの周囲の挟持部で挟持する等により、ポリ塩化ビニル、ポリエチレン、ポリエステル、珪砂などの保護膜を計測窓5aを覆うように着脱可能に設ける構成とても良好であり、前記構成により、計測窓5aを保護することができる。   Each component of the sorting apparatus is provided with a sensor as necessary, and the detection information of the sensor is analyzed by the control unit 7 or the like, and the control unit 7 or the like is installed according to the analysis result. It is preferable to adopt a configuration in which a component that is present or a component that needs to be operated in response to detection by the sensor is operated. In addition to the configuration in which the measurement is performed for each separation target S at the place where the measurement is performed, the fluorescent X-ray measurement is performed at a predetermined interval on the belt conveyor 3 by one measurement of the fluorescent X-ray measurement unit 5. It is also possible to perform measurement a plurality of times by the unit 5, the determination unit 8 obtains the average value of the measurement values of the plurality of floors, and classifies the entire measurement location based on the determination result comparing the average value and the threshold value It is. In addition, for example, a configuration in which a protective film such as polyvinyl chloride, polyethylene, polyester, or silica sand is detachably provided so as to cover the measurement window 5a by being clamped by a clamping portion around the measurement window 5a is very good. Thus, the measurement window 5a can be protected.

次に、第1実施形態の分別装置による分別方法について説明する。先ず、グリズリー1を備えているホッパー2に分別対象物Sを所定量投入し、一時貯留する。分別対象物Sの含水状態や性状に合わせてグリズリー1の備えられているバイブロモーターによってグリズリー1を振動させてもよい。また、グリズリー1を振動させる場合には、連続的に振動させてもいが、ホッパー2に分別対象物Sを投入する時やホッパー2に付着した分別対象物Sを落とす時等に間欠的に振動させてもよい。   Next, a sorting method by the sorting device of the first embodiment will be described. First, a predetermined amount of the separation object S is put into a hopper 2 provided with the grizzly 1, and temporarily stored. The grizzly 1 may be vibrated by a vibro motor provided with the grizzly 1 in accordance with the water content and properties of the separation target S. Further, when the grizzly 1 is vibrated, it may be continuously vibrated, but intermittently vibrates when the separation object S is put into the hopper 2 or when the separation object S attached to the hopper 2 is dropped. You may let them.

次いで、ベルトコンベア3を駆動させ、ホッパー2から分別対象物Sをベルトコンベア3に堆積させた状態で搬送する。ベルトコンベア3で搬送させてくる分別対象物Sは、ベルトコンベア3上で搬送されながらローラー4で押圧されて、表面が平滑にされると共に分別対象物Sの充填度が高められ、ローラー4により表面及び層を調整されると同時に、ローラー4のセンサー4aの計測情報から制御部7が分別対象物Sを検知する。尚、センサー4aが分別対象物Sを検知し、その検知情報を制御部7に出力する構成としてもよい。制御部7は、分別対象物Sが蛍光X線計測部5の計測窓5aの直下に位置した時点で搬送を停止する。   Next, the belt conveyor 3 is driven, and the separation object S is conveyed from the hopper 2 while being deposited on the belt conveyor 3. The separation object S conveyed by the belt conveyor 3 is pressed by the roller 4 while being conveyed on the belt conveyor 3, the surface is smoothed and the filling degree of the separation object S is increased. At the same time as the surface and the layer are adjusted, the control unit 7 detects the separation object S from the measurement information of the sensor 4 a of the roller 4. The sensor 4a may detect the separation target S and output the detection information to the control unit 7. The control unit 7 stops the conveyance when the separation target S is located immediately below the measurement window 5 a of the fluorescent X-ray measurement unit 5.

蛍光X線計測部5は、センサー5bの計測距離による制御部7の制御により、蛍光X線計測部5の計測窓5aの直下に位置する分別対象物Sの表面に計測窓5aが当接するまで駆動部5cで下降され、計測窓5aから分別対象物SにX線を照射し、前記照射によって発生する蛍光X線を計測窓5aから取得して、蛍光X線を計測する。制御部7の記憶部に設定されている所定時間が経過すると、制御部7の制御によって駆動部5cが駆動して蛍光X線計測部5が上昇する。更に、蛍光X線計測部5の上昇限で、図に省略した移動機構により清浄化部6が計測窓5aの直下まで移動し、清浄化部6が計測窓5aに付着した分別対象物Sを除去した後、清浄化部6は所定位置まで引き戻されるように移動する。   The fluorescent X-ray measurement unit 5 is controlled by the control unit 7 based on the measurement distance of the sensor 5b until the measurement window 5a comes into contact with the surface of the separation target S located immediately below the measurement window 5a of the fluorescent X-ray measurement unit 5. It is lowered by the drive unit 5c, X-rays are irradiated to the separation target S from the measurement window 5a, fluorescent X-rays generated by the irradiation are acquired from the measurement window 5a, and fluorescent X-rays are measured. When a predetermined time set in the storage unit of the control unit 7 elapses, the drive unit 5c is driven by the control of the control unit 7 and the fluorescent X-ray measurement unit 5 is raised. Furthermore, at the ascending limit of the fluorescent X-ray measurement unit 5, the cleaning unit 6 moves to a position immediately below the measurement window 5a by the moving mechanism omitted in the drawing, and the cleaning unit 6 removes the separation object S attached to the measurement window 5a. After the removal, the cleaning unit 6 moves so as to be pulled back to a predetermined position.

そして、制御部7はベルトコンベア3を作動させ、蛍光X線計測部5で計測された分別対象物Sをベルトコンベア3の端部まで搬送すると共に、判定部8に於ける特定元素の含有レベルの判定結果に怖じて、判定部8は分別部9であるガイド板を、特定元素が高含有レベルである搬送経路10或いは特定元素が低含有レベルである搬送経路11の何れかに向くように切り換え、ベルトコンベア3の端部まで搬送された分別対象物Sは搬送経路10或いは11に分別して仕分けられ、排出される。これらの工程は、全ての分別対象物Sの分別が終了するまで繰り返し、行われる。   Then, the control unit 7 operates the belt conveyor 3 to convey the separation object S measured by the fluorescent X-ray measurement unit 5 to the end of the belt conveyor 3, and the content level of the specific element in the determination unit 8. The determination unit 8 faces the guide plate which is the sorting unit 9 to either the conveyance path 10 where the specific element is at a high content level or the conveyance path 11 where the specific element is at a low content level. The separation object S that has been switched and conveyed to the end of the belt conveyor 3 is sorted into the conveyance path 10 or 11 and discharged. These steps are repeated until the separation of all the separation objects S is completed.

上記第1実施形態の分別装置及び分別方法は、特定元素を含む分別対象物Sをホッパー2からベルトコンベア3上に所定量を載置し、搬送方向にほぼ均等に堆積して送り出すことができる。そして、分別対象物Sを搬送しながらローラー4で分別対象物Sの表面や層を調整でき、更に、分別対象物Sに計測窓5aを当接して蛍光X線を計測し、また清浄化部6によって蛍光X線計測部5の計測窓5aを常に清潔に保つことができる。従って、分別対象物Sに含まれる特定元素の含有レベルの計測を正確に行うことができると共に、その計測を迅速かつ長期的、安定的に行うことができる。更に、このように計測された特定元素の含有レベルに基づき、連続的にベルトコンベア3から排出される分別対象物Sを分別し、特定元素の含有レベルの高い分別対象物Sと特定元素の含有レベルの低い分別対象物Sとに分けて異なる方向に搬出することができる。したがって、効率の良い分別が可能となり、分別された分別対象物Sに対してそれぞれの特定元素の含有レベルに応じた管理・利用を行うことができる。   In the separation apparatus and the separation method of the first embodiment, a predetermined amount of the separation object S containing a specific element can be placed on the belt conveyor 3 from the hopper 2, and can be deposited and sent out almost uniformly in the conveyance direction. . And the surface and layer of the classification target object S can be adjusted with the roller 4 while conveying the classification target object S, and also the measurement window 5a is brought into contact with the classification target object S to measure the fluorescent X-ray, and the cleaning unit 6, the measurement window 5a of the fluorescent X-ray measurement unit 5 can always be kept clean. Therefore, the content level of the specific element contained in the separation target S can be accurately measured, and the measurement can be performed quickly, stably over the long term. Furthermore, based on the content level of the specific element thus measured, the separation object S continuously discharged from the belt conveyor 3 is separated, and the content of the separation object S having a high content level of the specific element and the content of the specific element It can be carried out in different directions separately from the low-level separation object S. Therefore, efficient separation becomes possible, and management and use corresponding to the content level of each specific element can be performed on the sorted object S.

〔第2実施形態〕
次に、第2実施形態の分別装置について説明する。図2は第2実施形態の分別装置を示す側面説明図、図3は図2の分別装置に於ける振動篩近傍の拡大側面図、図4は図2の分別装置に於ける振動篩近傍の拡大平面図である。
[Second Embodiment]
Next, the sorting apparatus according to the second embodiment will be described. FIG. 2 is an explanatory side view showing the sorting device of the second embodiment, FIG. 3 is an enlarged side view of the vicinity of the vibrating screen in the sorting device of FIG. 2, and FIG. 4 is the vicinity of the vibrating screen in the sorting device of FIG. It is an enlarged plan view.

第2実施形態の分別装置は、図2に示すように、第1実施形態の分別装置に於けるホッパー2とローラー4との間の搬送経路に沿って、分級部に相当する振動篩12と、水分計13と、噴霧スプレー14と、平滑化部に相当するスクレーパー15と、水分計16とを上流側から下流側に向かって順次設置した構成であり、その他の基本的な構成は第1実施形態と同様である。グリズリー1によって粗粒分を分離除去しただけでは、分別対象物Sの表面の平滑さ、分別対象物Sの層の充填度が確保できない、或いは分別対象物S中に夾雑物が多く含まれる場合等には、分別対象物Sを搬送しながらベルトコンベア3上で通過する分別対象物Sを好ましくは10mm以下とする振動篩12を有する構成や、更に、前記分級後の分別対象物の表面を平滑にするスクレーパー15等を併用する第2実施形態の分別装置等とすると好適である。   As shown in FIG. 2, the sorting apparatus according to the second embodiment includes a vibrating screen 12 corresponding to a classifying unit along a conveyance path between the hopper 2 and the roller 4 in the sorting apparatus according to the first embodiment. The moisture meter 13, the spray spray 14, the scraper 15 corresponding to the smoothing unit, and the moisture meter 16 are sequentially installed from the upstream side to the downstream side, and the other basic configuration is the first. This is the same as the embodiment. When only the coarse particles are separated and removed by the grizzly 1, the smoothness of the surface of the separation object S, the filling degree of the layer of the separation object S cannot be ensured, or the separation object S contains a lot of impurities. For example, the structure having the vibrating sieve 12 that preferably sets the separation target S passing through the belt conveyor 3 while conveying the separation target S to 10 mm or less, and the surface of the classification target after classification. It is preferable to use the sorting apparatus or the like according to the second embodiment that uses a smoothing scraper 15 or the like together.

振動篩12は、分別対象物Sの搬送経路に於ける蛍光X線計測部5の上流側に設けられ、通過する分別対象物Sの粒径を所定粒径以下とするものであり、更に、振動篩12は、平滑化部に相当するスクレーパー15、ローラー4の上流側に設けられる。振動篩12は、図2〜図4に示すように、上下方向に支持される複数のバー12aを所定間隔で配列したものであり、バー12aの各々は上端がベルトコンベア3の移動方向に於ける下流側に後退するように突き出され、その上端が上流側に突き出され、斜めに傾斜して配置されている。複数のバー12aで構成されるスクリーンは、図4に示すように、ベルトコンベア3の幅方向の略中央に対応する箇所が上流側に突き出すようにして配置され、側縁に近づくに従って下流側に後退するようにしてバー12aが配置されている。複数のバー12aを通過する分別対象物Sの最大径はバー12a・12aの間隔によって調整され、望ましくは粒径2mm〜10mmまでの範囲で設定された値の粒径を通過するように複数のバー12aが配置されている。振動篩12には、スクリーンのバー12aの各々に振動が伝達されるようにしてバイブロモーター12bが取り付けられている。尚、前記振動篩12には、破損しにくく、目詰まりも生じにくいため、所定間隔で複数のバー12aが配置されたスクリーンが用いているが、前記スクリーンに代えて網状の部材を用いることも可能である。   The vibration sieve 12 is provided on the upstream side of the fluorescent X-ray measurement unit 5 in the conveyance path of the separation target S, and the particle size of the separation target S passing therethrough is a predetermined particle size or less. The vibrating sieve 12 is provided on the upstream side of the scraper 15 and the roller 4 corresponding to the smoothing unit. As shown in FIGS. 2 to 4, the vibrating screen 12 is formed by arranging a plurality of bars 12 a supported in the vertical direction at predetermined intervals, and each bar 12 a has an upper end in the moving direction of the belt conveyor 3. The upper end protrudes to the upstream side, and is inclined obliquely. As shown in FIG. 4, the screen composed of a plurality of bars 12 a is arranged such that a portion corresponding to the approximate center in the width direction of the belt conveyor 3 protrudes upstream, and toward the downstream as it approaches the side edge. The bar 12a is arranged so as to move backward. The maximum diameter of the separation object S that passes through the plurality of bars 12a is adjusted by the interval between the bars 12a and 12a, and preferably a plurality of particle sizes so as to pass through a particle size set in a range of 2 to 10 mm. Bar 12a is arranged. A vibrator motor 12b is attached to the vibration sieve 12 so that vibration is transmitted to each of the bars 12a of the screen. The vibrating sieve 12 is less likely to be broken and clogged, so a screen having a plurality of bars 12a arranged at predetermined intervals is used. However, a net-like member may be used instead of the screen. Is possible.

振動篩12は、スクリーンを振動させることによって分別対象物Sの分級を短時間で行うことができると同時に、分別対象物Sを混合・攪拌することが可能であり、分別対象物Sの特定元素の含有レベルの計測精度を高め、分別対象物Sの分別の効率を向上させることができる。特に、スクリーンの目開きが2mm程度と小さくなると、含水状態の分別対象物Sを分級する場合に目詰まりが生じやすくなるので、振動篩12の使用が有効となる。   The vibrating sieve 12 can classify the separation target S in a short time by vibrating the screen, and at the same time, can mix and agitate the separation target S. The specific element of the separation target S The measurement accuracy of the content level of can be increased, and the efficiency of the separation of the separation object S can be improved. In particular, when the screen aperture is as small as about 2 mm, clogging is likely to occur when classifying the water-containing separation target S, and therefore the use of the vibrating sieve 12 is effective.

振動篩12は、ベルトコンベア3上で搬送される分別対象物Sの上層部分に対応する位置で支持され、分別対象物Sの上層部分を分級可能になっており、前記搬送される分別対象物Sの上層部分が振動篩12に突き当たり、分別対象物S中の粗粒Srが所定間隔で配列されたスクリーンのバー12aで留められ、細粒Smがバー12a・12a間を通過し、搬送される分別対象物Sの上層部分を細粒分にすることが可能である。振動篩12を用いる場合は、振動篩12を通過した細粒分が堆積する層がX線の照射によって特定元素の含有レベルを計測する計測対象となる。バー12a・12aの間を通過しない粗粒Srで構成される粗粒分は、側縁に近づくに従って後退する位置に配置されたバー12aの配列方向に沿って側方に押し出され、ベルトコンベア3の側部に堆積される。   The vibration sieve 12 is supported at a position corresponding to the upper layer portion of the separation object S conveyed on the belt conveyor 3 and can classify the upper layer portion of the separation object S. The upper layer portion of S hits the vibrating screen 12, and the coarse particles Sr in the separation object S are fastened by the screen bars 12a arranged at predetermined intervals, and the fine particles Sm pass between the bars 12a and 12a and are conveyed. It is possible to make the upper layer portion of the separation object S to be fine particles. When the vibrating sieve 12 is used, the layer on which the fine particles that have passed through the vibrating sieve 12 are deposited becomes a measurement target for measuring the content level of the specific element by X-ray irradiation. The coarse particles composed of the coarse particles Sr that do not pass between the bars 12a and 12a are pushed out to the side along the arrangement direction of the bars 12a arranged at the positions where the bars 12a are retracted as they approach the side edges, and the belt conveyor 3 Deposited on the sides of the.

振動篩12は、ベルトコンベア3に対して上下方向に移動して位置調整可能な構成になっており、ベルトコンベア3で移動する分別対象物Sに接触しないように上方に移動して固定可能になっている。即ち、蛍光X線計測部5による特定元素の含有レベルの計測は、必ずしも連続的に行う必要はなく、間欠的に計測を行う場合には振動篩12がX線を照射して計測を行う部分のみについて分級を行ってもよい。そして、振動篩12が上部に移動して分別対象物Sから離れたときに、目詰まりを解消するように定期的な清掃や必要な場合にはスクリーンの交換を行うことが望ましい。尚、間欠的に蛍光X線の計測を行う場合等には、前記振動篩12と同様に、蛍光X線計測部5の上流側に位置し、分別対象物Sと接触するローラー4等の適宜部分を上下方向に移動可能に構成することが可能である。   The vibration sieve 12 is configured to be movable in the vertical direction with respect to the belt conveyor 3 so that the position thereof can be adjusted. The vibrating sieve 12 can be moved upward and fixed so as not to contact the separation object S moving on the belt conveyor 3. It has become. That is, the measurement of the content level of the specific element by the fluorescent X-ray measurement unit 5 is not necessarily performed continuously. In the case where measurement is performed intermittently, the vibration sieve 12 irradiates the X-ray and performs measurement. Classification may be performed only for. When the vibrating sieve 12 moves upward and leaves the separation target S, it is desirable to perform periodic cleaning and replace the screen when necessary so as to eliminate clogging. In addition, when measuring fluorescent X-rays intermittently, etc., as with the vibrating sieve 12, the rollers 4 etc. that are located upstream of the fluorescent X-ray measuring unit 5 and are in contact with the separation object S are appropriately selected. The part can be configured to be movable in the vertical direction.

水分計13は、ベルトコンベア3で搬送される汚染土壌等の分別対象物Sの含水率を測定するものであり、噴霧スプレー14は、水分計13で測定した含水率が所定値以下の場合に分別対象物Sに水を散布する噴霧スプレーである。前記水分計13の測定値は例えば制御部7に出力され、制御部7の演算処理部は記憶部の制御プログラムに従い、入力される水分計13の測定値と記憶部に設定記憶されている所定値とを対比し、前記所定値未満の含水率の場合に噴霧スプレー14で水を散布するように制御する。また、スクレーパー15は、ベルトコンベア3で搬送される分別対象物Sの表面を平滑にする均平板である。また、水分計16は、噴霧スプレー14で水を散布した後の分別対象物Sの含水率を測定するものであり、その測定結果は例えば制御部7に出力され、制御部7は記憶部の制御プログラムに従い、入力される水分計16の測定値と記憶部に設定記憶されている所定値とを対比し、前記所定値未満の含水率の場合に例えばベルトコンベア3での搬送を一旦停止するように制御する。尚、水分計13、噴霧スプレー14、スクレーパー15、水分計16を設けない分別装置とすることが可能であるのは当然である。   The moisture meter 13 measures the moisture content of the separation object S such as contaminated soil conveyed by the belt conveyor 3, and the spray spray 14 is used when the moisture content measured by the moisture meter 13 is a predetermined value or less. It is a spray spray that sprays water on the separation target S. The measured value of the moisture meter 13 is output to, for example, the control unit 7, and the arithmetic processing unit of the control unit 7 is set and stored in the measured value of the moisture meter 13 and the storage unit according to the control program of the storage unit. When the water content is less than the predetermined value, control is performed so that water is sprayed by the spray 14. Further, the scraper 15 is a flat plate that smoothes the surface of the separation object S conveyed by the belt conveyor 3. In addition, the moisture meter 16 measures the moisture content of the separation target S after the water is sprayed by the spray spray 14, and the measurement result is output to the control unit 7, for example, and the control unit 7 is stored in the storage unit. In accordance with the control program, the input measurement value of the moisture meter 16 is compared with a predetermined value set and stored in the storage unit, and when the moisture content is lower than the predetermined value, for example, conveyance on the belt conveyor 3 is temporarily stopped. To control. Of course, it is possible to provide a separation apparatus without the moisture meter 13, the spray spray 14, the scraper 15, and the moisture meter 16.

第2実施形態の分別装置による分別方法では、第1実施形態に於ける分別方法に於けるホッパー2とローラー4との間の工程で、振動篩12、水分計13、噴霧スプレー14、スクレーパー15、水分計16で所定の処理が行われること以外は第1実施形態と同様である。即ち、ホッパー2からベルトコンベア3で搬送される分別対象物Sの上層を振動篩12で細粒分にする処理が行われ、その後、水分計13で分別対象物Sの含水率を測定し、その測定結果により必要に応じて噴霧スプレー14で水を散布する。その後、スクレーパー15で分別対象物Sの表面を平滑にし、水分計16で確認のため分別対象物Sの含水率を再度計測する。その後、分別対象物Sには、ローラー4で更なる表面の平滑化と層の充填度を上げる処理がなされ、第1実施形態と同様に、蛍光X線の計測、分別が行われる。   In the separation method by the separation device of the second embodiment, the vibration sieve 12, the moisture meter 13, the spray 14 and the scraper 15 are the steps between the hopper 2 and the roller 4 in the separation method of the first embodiment. This is the same as in the first embodiment except that a predetermined process is performed by the moisture meter 16. That is, the upper layer of the separation target S conveyed from the hopper 2 by the belt conveyor 3 is processed to be finely divided by the vibrating sieve 12, and then the moisture content of the separation target S is measured by the moisture meter 13, According to the measurement result, water is sprayed by the spray 14 as necessary. Thereafter, the surface of the separation target S is smoothed by the scraper 15, and the moisture content of the separation target S is measured again for confirmation by the moisture meter 16. Thereafter, the separation object S is further processed with a roller 4 to further smooth the surface and increase the degree of filling of the layer, and measurement and separation of fluorescent X-rays are performed as in the first embodiment.

上記第2実施形態の分別装置及び分別方法は、第1実施形態と同様の効果を奏することに加え、振動篩12を平滑化部に相当するスクレーパー14やローラー4の上流側に設けることにより、分別対象物S中に粒径の大きなものが混在している場合に予め除去することができる。更に、スクレーパー14で分別対象物Sの表面を平滑にし、ローラー4で分別対象物Sの表面の更なる平滑化を図ると共に、層の充填度を高めることにより、蛍光X線計測部5の計測結果を飛躍的に高め、特定元素の含有レベルの判定結果を非常に正確なものとすることができる。   In addition to having the same effect as the first embodiment, the separation device and the separation method of the second embodiment, in addition to providing the vibrating sieve 12 on the upstream side of the scraper 14 and the roller 4 corresponding to the smoothing unit, It can be removed in advance when a large particle size is mixed in the separation object S. Furthermore, the surface of the separation target S is smoothed by the scraper 14, the surface of the separation target S is further smoothed by the roller 4, and the degree of filling of the layer is increased, whereby the measurement of the fluorescent X-ray measurement unit 5 is performed. The result can be greatly improved, and the determination result of the content level of the specific element can be made very accurate.

The determination unit 28 stores a control program, a table of content levels of specific elements corresponding to measured values of fluorescent X-rays, and a threshold value of content levels of specific elements corresponding to regulation values, etc. in the storage unit, The arithmetic processing unit recognizes the content level of the specific element corresponding to the measurement value input from the fluorescent X-ray measurement unit 25 from the table according to the control program, and compares the recognized content level with the threshold value. If it is less than the threshold, the separation unit 29 is controlled so as to make a route for reuse, etc., the bottom plate of the tray 32 is opened, and the separation object S is discharged to the separation unit 29.

As in the first embodiment, the processing for directly comparing the measurement value of the fluorescent X-ray measurement unit 25 with the threshold value, the configuration in which the determination unit 8 and the control unit 7 are the same hardware, etc. Is possible. The sorting unit 29 is a tilting plate that closes one of the entrances of the sorting paths 30 and 31 and opens the other. The sorting unit 29 switches to the sorting path 30 or 31 of the sorting object S according to the determination result of the determining unit 28 and performs sorting. Sort the object S.

第3実施形態の分別装置による分別方法では、落下調整機構21に分別対象物Sが投入され、分別対象物Sが排出口21bから振動篩22に排出される。振動篩22は所定粒径以下の分別対象物Sを通過させ、受皿32に落下させる。受皿32は、底板に貯溜されていく分別対象物Sの重量をセンサー32aで検知し、所定の重量に到達した場合に排出口21bを閉じて分別対象物Sの落下を停止する。その後、ローラー24を駆動して、受皿32上の分別対象物Sの表面を平滑にすると共に密度を高め、受皿32上の分別対象物Sを略平均した層厚にする。その後、蛍光X線計測部25を駆動して分別対象物Sに計測窓25aを当接し、計測窓25aからX線を照射して計測窓25aから蛍光X線を取り込み、蛍光X線の計測値を取得する。蛍光X線の計測値は判定部28に出力され、判定部28は前記蛍光X線の計測値に基づき特定元素の含有レベルを判定する。また、蛍光X線の計測完了に応じて、蛍光X線計測部25は分別対象物Sから離れて元の位置に復帰し、清浄化部26を駆動して計測窓25aの清浄化を行う。そして、判定部28の制御により、分別部29で仕分経路30、31の何れかが開放され、受皿32の底板を開放して受皿32上の分別対象物Sを開放された仕分経路30又は31に落下させる。尚、受皿32から分別部29に落下する構成に代え、例えば受皿32の部分が移動して搬送可能な構成とし、搬送された分別対象物Sを第1実施形態と同様な構成等で分別してもよい。   In the separation method by the separation apparatus of the third embodiment, the separation object S is input to the drop adjustment mechanism 21, and the separation object S is discharged from the discharge port 21b to the vibrating sieve 22. The vibration sieve 22 passes the separation object S having a predetermined particle size or less and drops it on the tray 32. The tray 32 detects the weight of the separation target S stored in the bottom plate by the sensor 32a, and when the predetermined weight is reached, closes the discharge port 21b and stops the separation target S from dropping. Thereafter, the roller 24 is driven to smooth the surface of the separation target S on the tray 32 and increase the density, so that the thickness of the separation target S on the tray 32 is approximately average. Thereafter, the fluorescent X-ray measurement unit 25 is driven to bring the measurement window 25a into contact with the separation object S, X-rays are emitted from the measurement window 25a, and the fluorescent X-rays are taken in from the measurement window 25a. To get. The measurement value of the fluorescent X-ray is output to the determination unit 28, and the determination unit 28 determines the content level of the specific element based on the measurement value of the fluorescent X-ray. Further, in response to the completion of the measurement of the fluorescent X-ray, the fluorescent X-ray measurement unit 25 moves away from the separation target S and returns to the original position, and drives the cleaning unit 26 to clean the measurement window 25a. Then, under the control of the determination unit 28, any of the sorting paths 30 and 31 is opened by the sorting unit 29, the bottom plate of the tray 32 is opened, and the sorting target S on the tray 32 is opened. Let fall. In addition, instead of the configuration of dropping from the tray 32 to the sorting unit 29, for example, a portion of the tray 32 can be moved and transported, and the transported separation object S is separated by the same configuration as in the first embodiment. Also good.

上記第3実施形態の分別装置及び分別方法は、第1実施形態と同様の効果を奏することに加え、分別対象物Sの重力落下を利用することにより、動力の省力化、動力コストの低減を図ることができる。また、動力箇所の削減により、装置の故障率を低減することが可能であり、操業の安定性を高めることができる。また、落下調整機構21内に貯留した分別対象物Sを重力によって固液分離し、分別対象物中の不要な含水分を予め落下させ、計測に適した含水率を担保することができる。また、例えば落下調整機構21内にグリズリーを配置するなど落下調整機構21内に分級部を設け、予め分別対象物Sに分級処理を施すことも可能である。前記構成により、粒径別に計測、あるいは特定粒径に絞った計測を行うことが可能となり、計測精度、効率を向上させる。   In addition to the same effects as the first embodiment, the separation device and the separation method of the third embodiment can save power and reduce power costs by using the gravity drop of the separation object S. Can be planned. Moreover, it is possible to reduce the failure rate of the apparatus by reducing the number of power points, and the operational stability can be improved. Further, the separation object S stored in the drop adjustment mechanism 21 is solid-liquid separated by gravity, and unnecessary moisture content in the separation object is dropped in advance, thereby ensuring a moisture content suitable for measurement. In addition, for example, a classification unit may be provided in the fall adjustment mechanism 21 such as by arranging a grizzly in the fall adjustment mechanism 21, and the classification target object S may be subjected to classification processing in advance. With the above-described configuration, it is possible to perform measurement for each particle size or measurement limited to a specific particle size, and improve measurement accuracy and efficiency.

〔第4実施形態〕
次に、第4実施形態の分別装置について説明する。図6は第4実施形態の分別装置に於ける蛍光X線計測部及びその動作機構を示す説明図である。第4実施形態の分別装置は、第1〜第3実施形態の分別装置の蛍光X線計測部に携帯(ハンドヘルド)型蛍光X線計測装置を用いるものであり、その他の基本的な構成は第1〜第3実施形態と同様である。
[Fourth Embodiment]
Next, a sorting apparatus according to the fourth embodiment will be described. FIG. 6 is an explanatory diagram showing a fluorescent X-ray measurement unit and its operation mechanism in the sorting apparatus of the fourth embodiment. The sorting apparatus according to the fourth embodiment uses a portable (handheld) type fluorescent X-ray measuring apparatus for the fluorescent X-ray measuring section of the sorting apparatus according to the first to third embodiments. The same as the first to third embodiments.

図6の蛍光X線計測部50は、携帯(ハンドヘルド)型蛍光X線計測装置51を取付部52の支持部材52aにボルト締め等で着脱可能に取り付けて構成され、携帯型蛍光X線計測装置51は図示省略する配線を介して制御部7、判定部8に接続されている。携帯型蛍光X線計測装置51は、単体で携帯して使用可能なものであり、装置内部のX線照射部から分別対象物Sの表面にX線を照射し、前記X線照射によって分別対象物Sに含まれる特定元素から発生する蛍光X線を装置内部の蛍光X線計測部で捉えて計測する。携帯型蛍光X線計測装置51には、X線を照射すると共に蛍光X線を取り込む計測窓51aが設けられている共に、計測操作を行う際のスイッチに相当するトリガー51bが設けられている。携帯型蛍光X線検出装置51を単体で使用する場合には、トリガー51bのオンオフは人手によって行われるが、インライン計測のために分別装置に設置する場合には開閉部52bがトリガー51bに取り付けられ、開閉部52bの進退によりトリガー51bがオンオフされる。開閉部52bは、油圧シリンダ、エアシリンダ若しくは電動シリンダのピストンロッド等とし、例えば制御部7からの図示省略する配線を介して送られる制御指令に応じて図示省略する駆動制御部がシリンダを駆動し、前記ピストンロッドの進退に応じて前記ピストンロッドに取り付けられたトリガー51bがオンオフされる構成とする。尚、X線の漏洩を防ぐために、携帯型蛍光X線計測装置51或いはX線の照射位置付近を覆うようにX線を遮断できる材料を用いたカバー(図示せず)等を設けることが好ましい。   The fluorescent X-ray measuring unit 50 in FIG. 6 is configured by attaching a portable (handheld) fluorescent X-ray measuring device 51 to a support member 52a of the mounting portion 52 so as to be detachable by bolting or the like. 51 is connected to the control part 7 and the determination part 8 via wiring not shown. The portable fluorescent X-ray measurement apparatus 51 can be carried alone and used to irradiate the surface of the separation target S from the X-ray irradiation unit inside the apparatus, and the target to be separated by the X-ray irradiation. The fluorescent X-ray generated from the specific element contained in the object S is captured and measured by the fluorescent X-ray measuring unit inside the apparatus. The portable fluorescent X-ray measurement apparatus 51 is provided with a measurement window 51a for irradiating X-rays and capturing fluorescent X-rays, and a trigger 51b corresponding to a switch for performing a measurement operation. When the portable X-ray fluorescence detector 51 is used alone, the trigger 51b is turned on and off manually. However, when the portable X-ray detector 51 is installed in a sorting device for in-line measurement, an opening / closing part 52b is attached to the trigger 51b. The trigger 51b is turned on / off by the advance / retreat of the opening / closing part 52b. The opening / closing unit 52b is a hydraulic cylinder, an air cylinder, a piston rod of an electric cylinder, or the like. For example, a drive control unit (not shown) drives the cylinder in response to a control command sent from the control unit 7 via a wiring (not shown). The trigger 51b attached to the piston rod is turned on / off according to the advance / retreat of the piston rod. In order to prevent leakage of X-rays, it is preferable to provide a portable fluorescent X-ray measuring device 51 or a cover (not shown) using a material capable of blocking X-rays so as to cover the vicinity of the X-ray irradiation position. .

蛍光X線計測部50には、蛍光X線計測部50を下降する電動シリンダ等の下降機構53が設けられており、下降機構53は蛍光X線計測部50をピストンロッド支持しながら蛍光X線計測部50を下降すると共に、下降機構53は下降途中に蛍光X線計測部50への支持を開放可能になっている。また、取付部52にはチェーン54の一端が取り付けられ、チェーン54はプーリ55に巻回されている。チェーン54の他端側はカウンターウエイト56に挿入され、その他端には支持板57が設けられている。カウンターウエイト56は、蛍光X線計測部50を下降する際には図に省略した保持部材で保持されるが、逆に蛍光X線計測部50を上昇する際には前記保持部材による保持が開放されて、自らの荷重が支持板57方向に負荷されるため、これらの荷重によって蛍光X線計測部50が上昇する。下降機構53、前記保持部材は制御部7からの制御指令に応じて動作する。   The fluorescent X-ray measurement unit 50 is provided with a lowering mechanism 53 such as an electric cylinder for lowering the fluorescent X-ray measurement unit 50. The lowering mechanism 53 supports the fluorescent X-ray measurement unit 50 while supporting the piston rod with the fluorescent X-rays. While lowering the measuring unit 50, the lowering mechanism 53 can open the support to the fluorescent X-ray measuring unit 50 during the lowering. One end of a chain 54 is attached to the attachment portion 52, and the chain 54 is wound around a pulley 55. The other end of the chain 54 is inserted into a counterweight 56, and a support plate 57 is provided at the other end. The counterweight 56 is held by a holding member (not shown) when the fluorescent X-ray measuring unit 50 is lowered, but conversely, the holding by the holding member is released when the fluorescent X-ray measuring unit 50 is raised. Then, since the own load is loaded in the direction of the support plate 57, the fluorescent X-ray measurement unit 50 is raised by these loads. The lowering mechanism 53 and the holding member operate according to a control command from the control unit 7.

携帯型蛍光X線計測装置51で蛍光X線を計測する時には、分別対象物Sを搬送するベルトコンベア3が停止し、蛍光X線計測部50に設けられているセンサー50aの計測窓51a直下で停止している分別対象物Sの検知に応じて、制御部7は、携帯型蛍光X線計測装置51が設けられている蛍光X線計測部50を所定位置まで下降し、分別対象物Sの表面と計測窓51aとが密接する。前記蛍光X線計測部50の下降では、蛍光X線計測部50を支持して蛍光X線計測部50の下降動作を行う下降機構53の蛍光X線計測部50に対する支持を途中で開放し、前記開放により蛍光X線計測部50が自重で下降する。前記下降時には、図に省略した油圧シリンダ、カウンターウエイト等の緩衝機構で緩衝させながら、蛍光X線計測部50の速度を調整して下降するようにすると、蛍光X線計測部50の下降動作が円滑になって好適である。従って、携帯型蛍光X線計測装置51の計測窓51aに、分別対象物Sに蛍光X線計測部50の自重以上の重さが掛からないようになっている。また、前記構成に代えて、携帯型蛍光X線計測装置51の計測窓51a付近に圧力センサー(図示せず)を設け、下降機構53に代わる蛍光X線計測部50を昇降する進退機構が蛍光X線計測部50の支持を持続して下降し、前記圧力センサーの計測窓51aと分別対象物Sとの間の圧力の検知に応じて、前記圧力を制御部7に出力し、例えば制御部7が記憶部に記憶する所定圧力に到達したことを認識し、前記進退機構による蛍光X線計測部50の下降を停止する構成とし、蛍光X線計測部50の自重未満の圧力だけが計測窓51aに負荷されるようにすることも可能である。係る構成とすることにより、携帯(ハンドヘルド)型蛍光X線計測装置50の計測窓51aを破損から保護し、長期的かつ安定的に判定、分別が行える。   When measuring the fluorescent X-rays with the portable fluorescent X-ray measurement device 51, the belt conveyor 3 that conveys the separation target S stops, and immediately below the measurement window 51a of the sensor 50a provided in the fluorescent X-ray measurement unit 50. In response to the detection of the separation object S that is stopped, the control unit 7 lowers the fluorescent X-ray measurement unit 50 provided with the portable fluorescent X-ray measurement device 51 to a predetermined position. The surface and the measurement window 51a are in close contact. When the fluorescent X-ray measuring unit 50 is lowered, the support for the fluorescent X-ray measuring unit 50 of the lowering mechanism 53 that supports the fluorescent X-ray measuring unit 50 and performs the lowering operation of the fluorescent X-ray measuring unit 50 is released halfway. As a result of the opening, the fluorescent X-ray measurement unit 50 is lowered by its own weight. At the time of the descent, the descent operation of the fluorescent X-ray measuring unit 50 is performed by adjusting the speed of the fluorescent X-ray measuring unit 50 while being buffered by a buffer mechanism such as a hydraulic cylinder and a counterweight not shown in the figure. It is smooth and suitable. Therefore, the classification window S of the portable fluorescent X-ray measuring apparatus 51 is not subjected to a weight more than the weight of the fluorescent X-ray measuring unit 50. Further, instead of the above-described configuration, a pressure sensor (not shown) is provided near the measurement window 51a of the portable fluorescent X-ray measurement device 51, and an advance / retreat mechanism that moves up and down the fluorescent X-ray measurement unit 50 instead of the lowering mechanism 53 is fluorescent. The support of the X-ray measurement unit 50 is continuously lowered, and the pressure is output to the control unit 7 in response to detection of the pressure between the measurement window 51a of the pressure sensor and the separation target S. For example, the control unit 7 recognizes that the predetermined pressure stored in the storage unit has been reached, and stops the lowering of the fluorescent X-ray measuring unit 50 by the advance / retreat mechanism, and only the pressure below the dead weight of the fluorescent X-ray measuring unit 50 is measured window It is also possible to load 51a. By adopting such a configuration, the measurement window 51a of the portable (handheld) type fluorescent X-ray measurement apparatus 50 is protected from breakage, and determination and separation can be performed for a long time and stably.

そして、計測窓51aが分別対象物Sの表面に密接した状態で、分別対象物Sに含まれる特定元素の含有レベルの計測を行う。前記計測時には、制御部7が記憶部に設定されている所定の自重降下確認時間の経過を自重降下時から内蔵タイマーの計測で認識し、前記認識に応じて開閉部52bを作動してトリガー51bをオンにし、記憶部に設定されている所定の計測時間を内蔵タイマーの計測で認識するまで前記オン状態を持続し、蛍光X線の計測を行う。前記蛍光X線の計測は一回でもよいが、複数回行ってその平均値を判定部8で取得するようにしてもよい。また、計測開始時には判定部8に携帯型蛍光X線計測装置51から計測開始信号が出力される。制御部7は前記設定されている所定計測時間が経過すると、開閉部52bを作動してトリガー51bをオフにし、オフになった携帯型蛍光X線計測装置51は判定部8に計測終了信号を出力し、判定部8は制御部7に計測終了信号を出力する。制御部7は前記計測終了信号の入力に応じて、カウンターウエイト56の保持を開放し、その荷重でチェーン54を引っ張って蛍光X線計測部50を上昇させる。更に、第1実施形態と同様に、上昇限で清浄化部6が計測窓51aの直下まで押し出され、計測窓51aに付着した分別対象物Sを除去した後、清浄化部6は所定位置まで引き戻される。尚、前記下降機構53に代えて、蛍光X線計測部50を昇降する電動シリンダ等の進退機構を設け、前記進退機構で蛍光X線計測部50を下降し、例えば自重開放持に油圧シリンダ等の緩衝機構で緩衝させながら自重で落下させる構成とし、又、例えば前記進退機構で蛍光X線計測部50を上昇させる際に、カウンターウエイト56の荷重を蛍光X線計測部50が上昇する方向に蛍光X線計測部に補助的に付加し、その戻り動作、上昇動作が円滑になるように構成してもよい。   And the content level of the specific element contained in the classification target object S is measured in the state where the measurement window 51a was in close contact with the surface of the classification target object S. At the time of the measurement, the control unit 7 recognizes the elapse of a predetermined dead weight check time set in the storage unit by the measurement of the built-in timer from the time of the dead weight drop, and operates the opening / closing unit 52b according to the recognition to trigger 51b. Is turned on and the on-state is maintained until the predetermined measurement time set in the storage unit is recognized by the measurement of the built-in timer, and the fluorescent X-ray is measured. The measurement of the fluorescent X-rays may be performed once, but may be performed a plurality of times and the average value may be acquired by the determination unit 8. At the start of measurement, a measurement start signal is output from the portable fluorescent X-ray measurement device 51 to the determination unit 8. When the set predetermined measurement time has elapsed, the control unit 7 operates the opening / closing unit 52b to turn off the trigger 51b, and the portable fluorescent X-ray measurement device 51 that has been turned off sends a measurement end signal to the determination unit 8. The determination unit 8 outputs a measurement end signal to the control unit 7. In response to the input of the measurement end signal, the control unit 7 releases the holding of the counterweight 56 and pulls the chain 54 with the load to raise the fluorescent X-ray measurement unit 50. Further, as in the first embodiment, the cleaning unit 6 is pushed out to the position immediately below the measurement window 51a at the ascending limit, and after the separation target S attached to the measurement window 51a is removed, the cleaning unit 6 reaches the predetermined position. Pulled back. Instead of the lowering mechanism 53, an advancing / retreating mechanism such as an electric cylinder for raising and lowering the fluorescent X-ray measuring unit 50 is provided, and the fluorescent X-ray measuring unit 50 is lowered by the advancing / retreating mechanism, for example, a hydraulic cylinder or the like for releasing its own weight. For example, when the fluorescent X-ray measuring unit 50 is raised by the advance / retreat mechanism, the load of the counterweight 56 is increased in the direction in which the fluorescent X-ray measuring unit 50 rises. You may add to an X-ray-fluorescence measurement part auxiliary, and you may comprise so that the return operation | movement and raise operation | movement may become smooth.
