Description

矿石分选装置Ore sorting equipment 技术领域Technical Field
本发明一般涉及矿石分选领域，尤其涉及矿石分选装置。The present invention generally relates to the field of ore sorting, and more particularly to an ore sorting device.
背景技术Background technique
目前，有价金属如铀、钍、铜、铁、金、铝等通常从矿石中提取。不同的矿石有价金属的含量参差不齐，在对矿石进行提炼之前，需要分选出有价金属含量较高的矿石，即精矿，对于有价金属含量较低的矿石，即尾矿，通常选择丢弃。At present, valuable metals such as uranium, thorium, copper, iron, gold, aluminum, etc. are usually extracted from ores. Different ores have different valuable metal contents. Before refining the ores, it is necessary to sort out the ores with higher valuable metal contents, i.e., concentrates, and the ores with lower valuable metal contents, i.e., tailings, are usually discarded.
传统的放射性选矿方案中，谱仪探测器往往排成一列置于放射性矿石槽道的正下方。***工作时，放射性矿石依次通过各谱仪探测器，谱仪探测器测得矿石的放射性计数，对比矿石的放射性计数和无放射性矿石时的本底计数，同时估算矿石的质量，进一步计算出矿石的比放射性水平，从而实现放射性矿石的分选工作。为了减小传送装置上相邻矿石的相互干扰，必须设置合适的屏蔽结构，因此探测器的测量时间利用率低，每个探测器的时间利用率不超过：谱仪对传送装置的可视距离/样品的间隔；这导致在选矿量一定的条件下需要较多的谱仪探测器，增加了设备的成本。In traditional radioactive mineral processing schemes, spectrometer detectors are often arranged in a row and placed directly below the radioactive ore trough. When the system is working, the radioactive ore passes through each spectrometer detector in turn. The spectrometer detector measures the radioactivity count of the ore, compares the radioactivity count of the ore with the background count of non-radioactive ore, estimates the mass of the ore, and further calculates the specific radioactivity level of the ore, thereby realizing the sorting of radioactive ore. In order to reduce the mutual interference of adjacent ores on the conveyor, a suitable shielding structure must be set up, so the measurement time utilization rate of the detector is low, and the time utilization rate of each detector does not exceed: the visual distance of the spectrometer to the conveyor/the interval of the sample; this leads to the need for more spectrometer detectors under the condition of a certain amount of mineral processing, which increases the cost of the equipment.
在基于XRF、(近)红外、LIBS、拉曼等探测技术的分选方案中，一般包含有上料装置、传送装置、光源与探测器、分选模块、控制模块、料仓。进行样品分选时，样品中目标原子或分子在光源的激发下会发出特征谱线，特征谱线反映了原子或分子的成分，特征谱线的强度则与物质的含量正相关。如果由于目标物质的含量低，导致需要的测量时间可能加长至s级甚至以上，此时在传送装置上流水线地完成样品的分选将成为不可能，或者将导致处理量无法满足要求。In the sorting scheme based on detection technologies such as XRF, (near) infrared, LIBS, Raman, etc., it generally includes a loading device, a conveyor, a light source and a detector, a sorting module, a control module, and a silo. When sorting samples, the target atoms or molecules in the sample will emit characteristic spectral lines under the excitation of the light source. The characteristic spectral lines reflect the composition of the atoms or molecules, and the intensity of the characteristic spectral lines is positively correlated with the content of the substance. If the content of the target substance is low, the required measurement time may be extended to S level or even higher. At this time, it will be impossible to complete the sorting of samples on the conveyor in an assembly line, or the processing volume will not meet the requirements.
另一方面，由于选矿时，需要根据矿石目标成分的相对含量来进行选矿，所以有时需要测量矿石样品的质量。传统的放射性选矿方案中，在传送装置上安装压力传感器来测量质量或者利用光学相机估算体积再根据密度估算质量。这两种测量方法的误差都较大，也使得放选的结果误差较大，导致选矿时误报率(false positive rate-FPR)和漏报率(false negative rate-FNR)都增高。 On the other hand, since mineral processing needs to be carried out based on the relative content of the target components of the ore, it is sometimes necessary to measure the mass of the ore sample. In traditional radioactive mineral processing schemes, a pressure sensor is installed on the conveyor to measure the mass or an optical camera is used to estimate the volume and then estimate the mass based on the density. Both of these measurement methods have large errors, which also makes the results of the selection process have large errors, resulting in increased false positive rate (FPR) and false negative rate (FNR) during mineral processing.

It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.
需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本公开。It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
本公开实施例提供一种矿石分选装置，包括：The present disclosure provides an ore separation device, comprising:
探测平台1，包括直列型设置的多个矿石容器4，所述矿石容器4用于容纳待探测矿石8，The detection platform 1 includes a plurality of ore containers 4 arranged in series, wherein the ore containers 4 are used to contain the ore 8 to be detected.
探测装置，探测装置设置在探测平台1的下方或者上方，用于通过探测将矿石分为不同等级，且每个矿石容器4对应有探测装置，The detection device is arranged below or above the detection platform 1 and is used to classify the ore into different grades by detection, and each ore container 4 has a corresponding detection device.
接料装置，设置在探测平台1两侧，包括用于容纳不同等级的矿石的至少两个容纳部， The receiving device is arranged on both sides of the detection platform 1, and includes at least two receiving parts for receiving ores of different grades.
矿石容器4可向靠近容纳部的方向转动，用于将矿石容器4内的矿石8移动至相应的容纳部内；The ore container 4 can be rotated toward the receiving portion to move the ore 8 in the ore container 4 to the corresponding receiving portion;
布料装置，包括多个传送装置7，多个传送装置7直列型设置，与矿石容器4一一对应设置。The material distribution device includes a plurality of conveying devices 7 , and the plurality of conveying devices 7 are arranged in series and correspond to the ore containers 4 one by one.
根据本公开实施例提供的矿石分选装置，通过在探测平台上设置直列型的多个矿石容器，能够适用于各种情况的矿石分选，例如放射性的分选方式，或者红外探测分选方式等等，具体可以通过设置不同的探测装置进行矿石的探测。在不同的情况下，采用不同类型的探测装置进行矿石的探测。例如，在对铀矿进行分选的情况下，可采用γ射线探测器作为探测装置。并且，本公开实施例中设置多个传送装置7作为布料装置，传送装置7也为直列型的设置方式，将传送装置7与矿石容器4一一对应，多个矿石容器4可同时进行布料，一次性完成一列矿石容器的布料工作，效率较高。According to the ore sorting device provided by the embodiment of the present disclosure, by setting a plurality of ore containers in a straight line on the detection platform, it can be applicable to ore sorting in various situations, such as a radioactive sorting method, or an infrared detection sorting method, etc. Specifically, different detection devices can be set to detect the ore. In different situations, different types of detection devices are used to detect the ore. For example, in the case of sorting uranium ore, a gamma-ray detector can be used as a detection device. In addition, in the embodiment of the present disclosure, a plurality of conveying devices 7 are set as distribution devices, and the conveying devices 7 are also set in a straight line. The conveying devices 7 are matched one by one with the ore containers 4, and the plurality of ore containers 4 can be distributed at the same time, and the distribution work of a row of ore containers can be completed at one time, which is more efficient.
根据本公开的矿石分选装置，在探测平台1上设置直列型的多个矿石容器4，并且将探测装置设置在相应的矿石容器4的上方或者下方，可以对应不同的矿石8的探测方式。例如，可以一次性将矿石8分别放置在各个矿石容器4后批量地进行探测并分选。探测装置与矿石8之间的立体角优选尽可能得大，由此保证矿石分选装置的时间利用效率，使得对矿石8的探测分选具有更高的效率。其中，一个锥面所围成的空间部分称为立体角。例如，以设置在矿石容器4下方的探测装置为球心做球面，探测装置至矿石之间的长度为半径，锥体在球表面截取的面积与球半径平方之比为当前的立体角。在本公开的矿石分选装置中，立体角为π/3以上，优选为π/2以上，更优选为π以上。According to the ore sorting device disclosed in the present invention, a plurality of ore containers 4 are arranged in a straight line on the detection platform 1, and the detection device is arranged above or below the corresponding ore container 4, which can correspond to different detection methods of the ore 8. For example, the ore 8 can be placed in each ore container 4 at one time and then detected and sorted in batches. The solid angle between the detection device and the ore 8 is preferably as large as possible, thereby ensuring the time utilization efficiency of the ore sorting device, so that the detection and sorting of the ore 8 has a higher efficiency. Among them, the space part surrounded by a cone is called a solid angle. For example, the detection device arranged below the ore container 4 is used as the center of the sphere to make a spherical surface, the length between the detection device and the ore is the radius, and the ratio of the area intercepted by the cone on the spherical surface to the square of the spherical radius is the current solid angle. In the ore sorting device disclosed in the present invention, the solid angle is greater than π/3, preferably greater than π/2, and more preferably greater than π.
在一个实施方式中，多个矿石容器4阵列型设置在探测平台1上，每行或者每列所述矿石容器4的探测进程可以相同或者不完全相同。In one embodiment, a plurality of ore containers 4 are arranged in an array on the detection platform 1, and the detection processes of the ore containers 4 in each row or column may be the same or different.
进一步地，本公开中直列型设置的多个矿石容器4可以包括阵列型设置的多个矿石容器4，其中该阵列具体为矩形阵列，即，多行多列的线性平面阵列。与此相对应地，布料装置也可以阵列型设置，但优选为对阵列设置的多个矿石容器4的一列或一行进行布料的可移动式布料装置。换言之，布料装置在同一时刻只能对一列或一行矿石容器进行布料，在完成该一列或一行的矿石容器的布料之后进行下一列或下一列等矿石容器的布料，由此依次完成对阵列设置的所有列或所有 行的矿石容器4的布料。Furthermore, the plurality of ore containers 4 arranged in a straight line in the present disclosure may include a plurality of ore containers 4 arranged in an array, wherein the array is specifically a rectangular array, that is, a linear plane array of multiple rows and columns. Correspondingly, the material distribution device may also be arranged in an array, but is preferably a movable material distribution device for distributing material to one column or one row of the plurality of ore containers 4 arranged in an array. In other words, the material distribution device can only distribute material to one column or one row of ore containers at the same time, and after the distribution of the ore containers in the column or one row is completed, the distribution of the next column or the next row and so on is carried out, thereby completing the distribution of material to all columns or all rows of the array in sequence. Row of ore containers 4 cloth.
在本公开中，在进行矿石8的探测分选的过程中，首先需要通过布料装置将矿石8移动至相应的矿石容器4，随后在矿石容器4中进行相应的探测，最后将探测好的矿石移动至相应的接料装置中，因此，至少包括布料、探测和分选三个步骤。根据本公开中的阵列型设置的多个矿石容器4进行矿石8的放置和探测，相比较图1至图4的单列设置的结构，每个矿石容器4进行矿石探测的进程可以不完全相同，优选地可以设置每行或者每列的矿石容器4进行相同的操作，不同行或者列之间的操作不相同。例如在阵列设置有五列矿石容器4的情况下，一组移动地设置的布料装置依次对各列的矿石容器4进行布料，当第一列布料完成后，布料装置移动至第二列进行布料操作，与此同时开始对第一列矿石容器4中的矿石进行探测，随后布料装置顺次移动至第三、第四、第五列进行布料操作，例如在布料装置在第五列进行布料操作时，对第一列矿石容器4中的完成了探测的矿石8进行分选，如此，能够使得该矿石分选装置的布料、探测和分选滚动循环起来，探测效率更高。另外一个优势就是，可以显著减少接料装置的数量，例如在某两列矿石容器4放置一列接料装置即可，即接料装置的数量(列数)＝放置区的列数+1即可。In the present disclosure, in the process of detecting and sorting the ore 8, the ore 8 needs to be first moved to the corresponding ore container 4 by the distribution device, then the corresponding detection is performed in the ore container 4, and finally the detected ore is moved to the corresponding receiving device, so at least three steps of distribution, detection and sorting are included. According to the array-type arrangement of multiple ore containers 4 in the present disclosure, the ore 8 is placed and detected. Compared with the single-row arrangement structure of Figures 1 to 4, the process of ore detection of each ore container 4 may not be exactly the same. Preferably, the ore containers 4 in each row or column can be set to perform the same operation, and the operations between different rows or columns are different. For example, in the case where the array is provided with five rows of ore containers 4, a group of movable distribution devices distribute the ore containers 4 of each row in turn. When the distribution of the first row is completed, the distribution device moves to the second row for distribution operation, and at the same time begins to detect the ore in the first row of ore containers 4. Then the distribution device moves to the third, fourth, and fifth rows in sequence for distribution operation. For example, when the distribution device is distributing in the fifth row, the ore 8 in the first row of ore containers 4 that has completed detection is sorted. In this way, the distribution, detection and sorting of the ore sorting device can be rolled and circulated, and the detection efficiency is higher. Another advantage is that the number of receiving devices can be significantly reduced. For example, one row of receiving devices can be placed in two rows of ore containers 4, that is, the number of receiving devices (number of rows) = the number of rows of the placement area + 1.
予以说明，阵列型设置的矿石容器4的行数和列数可根据布料、探测和/或分选的所需时间等适当选择。It should be noted that the number of rows and columns of the ore containers 4 arranged in an array can be appropriately selected according to the time required for material distribution, detection and/or sorting, etc.
在一个实施方式中，直列型设置的多个矿石容器4设置于可旋转的结构，例如可绕轴心旋转的滚筒。滚筒的圆周侧壁可以由沿轴向延伸的间隔设置的多个支撑板构成，每个支撑板上设置有一列矿石容器4。每个支撑板可以水平设置，由此当滚筒旋转的时候，支撑板也不会改变其水平设置的形式，将矿石放置在相应的支撑板上，滚筒旋转带动支撑板和上方的矿石结构一起旋转。支撑板可视为探测平台。此外，每个支撑板可以设置有挂钩部或者铰接部，每个矿石容器4通过挂钩部或者铰接部与支撑板连接，当滚筒旋转的时候，矿石容器4依靠自身重力竖直悬挂于支撑板，即在滚筒旋转的过程中，矿石容器4可以始终保持水平。在此，矿石容器4在将矿石移动至接料装置时的转动可以通过辅助机构(例如伸缩杆)完成。布料装置可以设置在滚筒的上方，以便于对位于最高处的矿石容器进行布料，接料装置可以设置 在滚动的下方，以便于容纳位于最低处的、完成探测的矿石。在矿石分选装置工作时，对某个撑板上的矿石容器4可进行布料，随后该矿石容器4离开布料装置开始进行探测，下一个支撑板通过旋转带动矿石容器4至布料装置的下方以进行布料，在矿石容器4旋转至滚筒的最下方时进行分选，落入相应的接料装置，如此循环。因此，一个滚筒上的支撑板可以同时进行探测、布料和分选，探测效率更高。予以说明，滚筒的支撑板的个数、旋转速度、布料装置及接料装置的设置位置可根据布料、探测和/或分选的所需时间等适当选择。In one embodiment, a plurality of ore containers 4 arranged in a straight line are arranged on a rotatable structure, such as a drum rotatable around an axis. The circumferential side wall of the drum can be composed of a plurality of support plates arranged at intervals extending in the axial direction, and a row of ore containers 4 is arranged on each support plate. Each support plate can be arranged horizontally, so that when the drum rotates, the support plate will not change its horizontal arrangement. The ore is placed on the corresponding support plate, and the rotation of the drum drives the support plate and the ore structure above to rotate together. The support plate can be regarded as a detection platform. In addition, each support plate can be provided with a hook portion or a hinge portion, and each ore container 4 is connected to the support plate through the hook portion or the hinge portion. When the drum rotates, the ore container 4 is vertically suspended on the support plate by its own gravity, that is, during the rotation of the drum, the ore container 4 can always remain horizontal. Here, the rotation of the ore container 4 when moving the ore to the receiving device can be completed by an auxiliary mechanism (such as a telescopic rod). The distribution device can be arranged above the drum to facilitate the distribution of the ore container located at the highest point. The receiving device can be provided with a hook portion or a hinge portion. Under the roller, in order to accommodate the ore that has been detected and is at the lowest point. When the ore sorting device is working, the ore container 4 on a certain support plate can be distributed, and then the ore container 4 leaves the distribution device and starts to detect. The next support plate drives the ore container 4 to the bottom of the distribution device by rotation for distribution. When the ore container 4 rotates to the bottom of the roller, it is sorted and falls into the corresponding receiving device, and the cycle continues. Therefore, the support plate on a roller can detect, distribute and sort at the same time, and the detection efficiency is higher. It should be noted that the number of support plates of the roller, the rotation speed, the location of the distribution device and the receiving device can be appropriately selected according to the time required for distribution, detection and/or sorting.
图5示意性示出可旋转滚筒式基本结构，其中滚筒上设置有四个支撑板。直列的矿石容器4垂直于纸面方向放置。图5中未图示布料装置(例如传送装置)和接料装置，但如上所述，布料装置和接料装置的设置位置可根据实际情况进行适当选择。FIG5 schematically shows a basic structure of a rotatable drum, wherein four support plates are arranged on the drum. The in-line ore containers 4 are placed perpendicular to the paper surface. FIG5 does not show a material distribution device (such as a conveyor device) and a material receiving device, but as mentioned above, the locations of the material distribution device and the material receiving device can be appropriately selected according to actual conditions.
本公开的矿石分选装置上设置接料装置进行不同等级的矿石的容纳，其包括至少两个容纳部，用于容纳至少两个不同等级的矿石，例如精矿和贫矿两个等级。在一个实施方式中，接料装置包括第一料仓2和第二料仓3，其中第一料仓2和第二料仓3可分别设置在探测平台1的两侧。在本公开中，可以根据矿石8实际要区分的等级来调整料仓的数量。本实施例中通过设置可向不同方向翻转的矿石容器将探测好的矿石移动至相应的料仓内，控制矿石容器翻转的方向和/或角度不同，可以将不同的矿石落到不同的料仓内。The ore sorting device of the present disclosure is provided with a receiving device for accommodating ores of different grades, and includes at least two accommodating parts for accommodating at least two different grades of ores, such as two grades of concentrate and lean ore. In one embodiment, the receiving device includes a first silo 2 and a second silo 3, wherein the first silo 2 and the second silo 3 can be respectively arranged on both sides of the detection platform 1. In the present disclosure, the number of silos can be adjusted according to the grades of the ore 8 to be actually distinguished. In this embodiment, an ore container that can be flipped in different directions is provided to move the detected ore into the corresponding silo, and the flipping direction and/or angle of the ore container is controlled differently, so that different ores can fall into different silos.
在一个实施方式中，接料装置为长条形，沿探测平台1的长度方向或者宽度方向延伸。In one embodiment, the material receiving device is in the shape of an elongated strip, extending along the length direction or the width direction of the detection platform 1 .
由于本公开提供的探测平台上的矿石容器4是直列型，或者阵列型的，每行或者每列的矿石容器4进行探测后，分选的不同等级的矿石也是汇集到一起，优选地在每行或者每列矿石容器4两侧设置长条形的接料装置，相邻行或者相邻列的矿矿石容器4之间可以共用一个接料装置，也可以根据情况设置多个。Since the ore containers 4 on the detection platform provided by the present invention are of a straight-line or array type, after the ore containers 4 in each row or column are detected, the ores of different grades are sorted together. Preferably, long strip-shaped material receiving devices are arranged on both sides of each row or column of ore containers 4. The ore containers 4 in adjacent rows or columns can share one material receiving device, or multiple devices can be arranged according to the situation.
其中，根据本公开提供的矿石分选装置，在对矿石容器4进行矿石8的布料以及探测完成后，矿石容器4可容易地进行翻转，翻转方向为靠近容纳部，即第一料仓2的方向或者靠近第二料仓3的方向。以图2和图4为例，矿石8通过矿石容器4的翻转容易向左或者右下落至相应的料仓内，本实施例中优选地在矿石容器4内设置旋转轴5 (图中虚线标出)进行转动；为了保证翻转后矿石下落的效率，本实施例中优选地设置矿石容器4每次翻转的角度为60°至90°，矿石容器两侧壁的倾斜角度为30°至45°(该倾斜角度是指矿石容器4侧壁与该容器中心轴线之间的夹角)，通过倾斜的矿石容器4侧壁顺利地将矿石翻转至相应的料仓内，并且矿石容器4无需翻转过大的角度即可实现矿石的移动，节省了时间。According to the ore sorting device provided by the present disclosure, after the ore container 4 is placed and detected, the ore container 4 can be easily flipped, and the flipping direction is close to the accommodation part, that is, the direction of the first silo 2 or the direction of the second silo 3. Taking Figures 2 and 4 as examples, the ore 8 can easily fall to the left or right into the corresponding silo through the flipping of the ore container 4. In this embodiment, a rotating shaft 5 is preferably provided in the ore container 4. (marked with dotted lines in the figure) for rotation; in order to ensure the efficiency of the ore falling after the flipping, in this embodiment, the flipping angle of the ore container 4 is preferably set to 60° to 90° each time, and the inclination angle of the two side walls of the ore container is 30° to 45° (the inclination angle refers to the angle between the side wall of the ore container 4 and the central axis of the container), and the ore is smoothly flipped into the corresponding silo by the inclined side wall of the ore container 4, and the ore container 4 does not need to be flipped too much to achieve the movement of the ore, saving time.
在一个实施方式中，每个矿石容器4底部均设有压力传感器，用于探测待探测矿石8的质量。In one embodiment, a pressure sensor is provided at the bottom of each ore container 4 for detecting the quality of the ore 8 to be detected.
本实施例中直接将探测矿石质量的压力传感器安装在矿石容器4底部，矿石8放置在矿石容器4内进行探测的时候，矿石8与压力传感器之间没有相对运动，质量探测较为准确，能够减小误报率和漏报率。In this embodiment, the pressure sensor for detecting the ore quality is directly installed at the bottom of the ore container 4. When the ore 8 is placed in the ore container 4 for detection, there is no relative movement between the ore 8 and the pressure sensor, and the quality detection is more accurate, which can reduce the false alarm rate and the missed alarm rate.
在一个实施方式中，相邻矿石容器4之间设有屏蔽隔板10。In one embodiment, shielding partitions 10 are provided between adjacent ore containers 4 .
在该实施方式中，为了保证一次探测的矿石8的数量，增加探测效率，相邻的矿石容器4之间的间距可以设置得较小，即对于相同大小的探测平台，可以增加矿石容器4的数量。另外，相邻的矿石容器4之间可以设置屏蔽隔板10，保证相邻的探测装置之间，以及相邻的矿石8的彼此之间不产生影响，用以减轻或消除相邻矿石8进行探测的时候相互之间的不良影响。屏蔽隔板10可以为铅板、钢板等。在另一个实施方式中，屏蔽隔板10在探测平台1的表面上可移动和/或可拆卸地设置，由此，可根据实际需求调整各矿石容器4的大小。同样地，与矿石容器4对应设置的一个或多个探测装置也可以可移动和/或可拆卸地设置。In this embodiment, in order to ensure the number of ores 8 detected at one time and increase the detection efficiency, the spacing between adjacent ore containers 4 can be set to be smaller, that is, for the detection platform of the same size, the number of ore containers 4 can be increased. In addition, shielding baffles 10 can be set between adjacent ore containers 4 to ensure that there is no influence between adjacent detection devices and adjacent ores 8, so as to reduce or eliminate the adverse effects between adjacent ores 8 when detecting. The shielding baffles 10 can be lead plates, steel plates, etc. In another embodiment, the shielding baffles 10 are movably and/or detachably arranged on the surface of the detection platform 1, thereby, the size of each ore container 4 can be adjusted according to actual needs. Similarly, one or more detection devices corresponding to the ore container 4 can also be movably and/or detachably arranged.
如图1至图4所示，本实施例提供直列型的探测平台1，并且探测平台1上设置多个矿石容器4进行探测，因此，通过设置传送装置7将矿石传递至相应的探测位置进行探测，优选地在每个矿石容器4均对应设置有一个传送装置7，这样每个矿石容器4都有独立的传送装置进行矿石8的传递，相互之间不会产生影响，若某一个矿石容器4的探测出现问题，可以单独的对该位置以及该位置对应的传送装置暂停工作，进行检修，其他矿石容器4的探测以及传送装置7的工作不会产生任何影响。As shown in FIGS. 1 to 4 , the present embodiment provides an in-line detection platform 1 , and a plurality of ore containers 4 are arranged on the detection platform 1 for detection. Therefore, a conveying device 7 is arranged to transfer the ore to the corresponding detection position for detection. Preferably, a conveying device 7 is arranged corresponding to each ore container 4 , so that each ore container 4 has an independent conveying device to transfer the ore 8 , and they will not affect each other. If there is a problem with the detection of a certain ore container 4 , the position and the conveying device corresponding to the position can be suspended and repaired separately, and the detection of other ore containers 4 and the work of the conveying device 7 will not be affected.
优选地还可以设置一个主传送装置和多个子传送装置，多个子传 送装置对应不同的矿石容器4，主传送装置可以与子传送装置相连接，连接点处设置转向机构，矿石可以不进行区分直接放置在主传送装置上，通过各个转向机构将不同的矿石移动至不同的子传送装置上，进而移动至相应的矿石容器4(该结构中的主传送装置并未在图中示出)，使得待探测矿石的移动更加的便捷。Preferably, a main transmission device and a plurality of sub-transmission devices may be provided. The conveying devices correspond to different ore containers 4. The main conveying device can be connected to the sub-conveyor device. A steering mechanism is set at the connection point. The ore can be placed directly on the main conveying device without distinction. Different ores are moved to different sub-conveyor devices through various steering mechanisms, and then moved to the corresponding ore container 4 (the main conveyor device in this structure is not shown in the figure), making the movement of the ore to be detected more convenient.
本公开中的矿石容器4还可以设置为阵列的形式，在阵列设置的矿石容器4上方设置的传送装置可设置为可移动的形式，沿矿石容器4的行方向或者列方向进行移动，移动至相应的矿石容器4上方，即可实现对下方探测位置的布料。The ore container 4 in the present disclosure can also be arranged in the form of an array, and the conveying device arranged above the ore container 4 arranged in the array can be arranged in a movable form, and can be moved along the row direction or column direction of the ore container 4, and moved to the top of the corresponding ore container 4, so as to realize the distribution of the detection position below.
进一步地，每个传送装置7的传输末端均设置在对应的矿石容器4上方。Furthermore, the transmission end of each conveying device 7 is arranged above the corresponding ore container 4 .
本实施例中通过传送装置7将相应的矿石8传递至探测平台1的矿石容器4内，优选地将传送装置7的末端设置在相应的矿石容器4上方，便于矿石准确掉落至矿石容器4内，或者根据传送装置7的移动速度，将传送装置7的末端设置在矿石容器4上方附近，只要能够将传送装置7上的矿石8传送至相应的矿石容器4即可。In this embodiment, the corresponding ore 8 is transferred to the ore container 4 of the detection platform 1 by the conveying device 7. Preferably, the end of the conveying device 7 is arranged above the corresponding ore container 4 to facilitate the ore to fall accurately into the ore container 4. Alternatively, according to the moving speed of the conveying device 7, the end of the conveying device 7 is arranged near the top of the ore container 4, as long as the ore 8 on the conveying device 7 can be conveyed to the corresponding ore container 4.
在本公开中，布料装置还可以采取其他的形式，例如直接采用机械抓手进行相应矿石的抓取，或者采用可移动式的网兜等结构进行矿石的移动，或者采用多根管道进行布料，不同的管道连接至不同的矿石容器4。In the present disclosure, the material distribution device can also take other forms, such as directly using a mechanical gripper to grab the corresponding ore, or using a movable net bag or other structure to move the ore, or using multiple pipes for distribution, with different pipes connected to different ore containers 4.
本实施例中的矿石分选装置在使用的时候，首先传送装置7上的矿石8落入矿石容器4内，容器底部的压力传感器6进行矿石质量的探测，同时，设置在矿石容器4附近的探测器进行矿石的探测，判断矿石的情况，例如根据矿石8的比放射性活度来判断矿石是精矿还是非精矿，进而通过矿石容器4的翻转将矿石倾倒至对应的料仓内，实现不同等级矿石的分离。When the ore sorting device in this embodiment is in use, first, the ore 8 on the conveyor 7 falls into the ore container 4, and the pressure sensor 6 at the bottom of the container detects the quality of the ore. At the same time, the detector arranged near the ore container 4 detects the ore to determine the condition of the ore, for example, whether the ore is a concentrate or a non-concentrate according to the specific radioactivity activity of the ore 8, and then the ore container 4 is turned over to dump the ore into the corresponding silo to achieve separation of ores of different grades.
上述实施方式中提供了多种矿石分选装置，其均具有用于探测矿石的质量的压力传感器6，能够直接对矿石8的质量进行探测。压力传感器6可以直接安装在探测平台1的矿石容器4的下方，矿石8与探测平台1之间没有相对移动，矿石的质量探测更加准确。此外，采用本公开中的直列型结构的矿石分选装置，能够提高矿石的探测效率。例如，放射性矿石的探测判断时间为0.8s，布料和卸料的时间各约需 0.1s，在矿石分选装置具有10个矿石容器4的情况下，可以同时完成10个矿石容器4内的矿石8的分选，并且可以循环地进行矿石的布料、探测、分析和分选操作，同时，探测装置的时间利用率可达到80％，大大提高了探测效率。在采用阵列型的矿石容器4的情况下，能够批量地进行多列矿石容器4中的矿石的布料、探测、分析和分选操作，进一步提高探测效率。予以说明，在本公开中，在具有压力传感器6的情况下，术语“探测”包含探测装置的探测和压力传感器6的质量探测，除非另外指出。The above embodiments provide a variety of ore sorting devices, all of which have a pressure sensor 6 for detecting the quality of the ore, and can directly detect the quality of the ore 8. The pressure sensor 6 can be directly installed below the ore container 4 of the detection platform 1. There is no relative movement between the ore 8 and the detection platform 1, and the quality detection of the ore is more accurate. In addition, the ore sorting device using the in-line structure of the present disclosure can improve the detection efficiency of the ore. For example, the detection judgment time of radioactive ore is 0.8s, and the time for laying and unloading is about 1. 0.1s, when the ore sorting device has 10 ore containers 4, the ores 8 in the 10 ore containers 4 can be sorted at the same time, and the ore distribution, detection, analysis and sorting operations can be carried out cyclically. At the same time, the time utilization rate of the detection device can reach 80%, which greatly improves the detection efficiency. In the case of using an array-type ore container 4, the ore distribution, detection, analysis and sorting operations in multiple columns of ore containers 4 can be carried out in batches, further improving the detection efficiency. It should be noted that in the present disclosure, in the case of a pressure sensor 6, the term "detection" includes detection by the detection device and quality detection by the pressure sensor 6, unless otherwise specified.
本实施例提供的装置在矿石装料和矿石容器翻转所占时间比例低的情况下，能够提高探测器的时间利用效率。The device provided in this embodiment can improve the time utilization efficiency of the detector when the proportion of time occupied by ore loading and ore container turning is low.
在本公开的实施方式中，矿石分选装置还包括控制装置，控制装置与探测装置、矿石容器4、设置在探测平台1上的压力传感器6等通信连接。当矿石放置在探测平台1(具体为矿石容器4)上的时候，压力传感器6进行探测，探测装置也同时对探测平台1上的矿石进行探测，将探测结果发送至控制装置，控制装置基于相应的探测结果，计算矿石中特定元素的含量，优选地与预先存储在控制装置的储存器内的矿石等级标准进行对比，由此将矿石划分为不同等级。当矿石探测完成后，控制装置进行其他结构的操作(例如矿石容器4的翻转)，将探测完成的矿石移动至接料装置中。In the embodiment of the present disclosure, the ore sorting device further includes a control device, which is in communication connection with the detection device, the ore container 4, the pressure sensor 6 arranged on the detection platform 1, etc. When the ore is placed on the detection platform 1 (specifically the ore container 4), the pressure sensor 6 performs detection, and the detection device also detects the ore on the detection platform 1 at the same time, and sends the detection result to the control device. The control device calculates the content of specific elements in the ore based on the corresponding detection result, and preferably compares it with the ore grade standard pre-stored in the storage of the control device, thereby classifying the ore into different grades. After the ore detection is completed, the control device performs other structural operations (such as turning over the ore container 4) to move the detected ore to the receiving device.
具体地，控制装置与矿石容器4通信连接，当矿石探测完成控制装置接收到探测结果后，控制装置控制矿石容器4进行相应的分选动作，将不同等级的矿石送入相应的容纳部，例如控制器控制矿石容器4向不同的方向翻转，相应的矿石落到不同的料仓内。Specifically, the control device is connected to the ore container 4 for communication. When the ore detection is completed and the control device receives the detection result, the control device controls the ore container 4 to perform corresponding sorting actions to send ores of different grades into corresponding containing parts. For example, the controller controls the ore container 4 to flip in different directions, and the corresponding ores fall into different silos.
在一个实施方式中，控制装置还与布料装置通信连接，在探测平台1上未放置矿石进行探测之前，控制装置控制布料装置进行矿石的布料，将矿石放置在探测平台上的不同的矿石容器4；在矿石容器4将矿石送入不同的容纳部之后，再控制布料装置在矿石已经分选好的位置上重新进行矿石的布置，例如当布料装置为上述实施方式中的传送装置结构时，通过控制传送装置的行进速度或者启停时间将矿石投放至各个矿石容器4。In one embodiment, the control device is also communicatively connected with the distribution device. Before ore is placed on the detection platform 1 for detection, the control device controls the distribution device to distribute the ore and places the ore in different ore containers 4 on the detection platform. After the ore container 4 delivers the ore into different containing parts, the distribution device is controlled to rearrange the ore at the position where the ore has been sorted. For example, when the distribution device is the conveying device structure in the above embodiment, the ore is delivered to each ore container 4 by controlling the travel speed or start and stop time of the conveying device.
