Description

Ore sorting device

Technical Field

The present utility model relates generally to the field of ore sorting and, more particularly, to an ore sorting apparatus.

Background

Currently, valuable metals such as uranium, thorium, copper, iron, gold, aluminum, etc. are commonly extracted from ores. The different ores have uneven valuable metal content, and ores with higher valuable metal content, namely concentrates, need to be separated before the ores are refined, and ores with lower valuable metal content, namely tailings, are usually discarded.

In conventional radioactive beneficiation schemes, the spectrometer detectors are often placed in a line directly below the radioactive ore channels. When the system works, radioactive ores sequentially pass through each spectrometer detector, the spectrometer detectors measure the radioactive counts of the ores, the radioactive counts of the ores are compared with the background counts of the ores without the radioactive ores, the quality of the ores is estimated, and the specific radioactive level of the ores is further calculated, so that the sorting work of the radioactive ores is realized. In order to reduce the mutual interference of adjacent ores on the conveyor, a suitable shielding structure must be provided, so that the measuring time utilization rate of the detectors is low, and the time utilization rate of each detector does not exceed: the spectrometer is a visual distance to the conveyor/a separation of samples; this results in the need for more spectrometer detectors at a certain beneficiation level, increasing the cost of the equipment.

In the sorting scheme based on detection technologies such as XRF, (near) infrared, LIBS, raman and the like, a feeding device, a conveying device, a light source, a detector, a sorting module, a control module and a bin are generally included. When the sample is sorted, target atoms or molecules in the sample can emit characteristic spectral lines under the excitation of a light source, the characteristic spectral lines reflect the components of the atoms or molecules, and the intensity of the characteristic spectral lines is positively related to the content of the substances. If the required measurement time is possibly lengthened to s-class or more due to the low content of the target substance, it becomes impossible to finish sorting of the sample in a pipeline on the conveyor, or the throughput may be insufficient.

On the other hand, in the case of ore dressing, it is necessary to carry out ore dressing based on the relative content of the target component of the ore, and therefore it is sometimes necessary to measure the mass of the ore sample. In conventional radioactive beneficiation schemes, pressure sensors are mounted on the conveyor to measure mass or an optical camera is used to estimate volume and then mass based on density. The errors of the two measuring methods are larger, so that the error of the result of the selection is larger, and the false positive rate (false positive rate-FPR) and the false positive rate (false negative rate-FNR) are increased during mineral separation.

Detailed Description

The present disclosure is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be noted that, for convenience of description, only the portions related to the utility model are shown in the drawings.

It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Embodiments of the present disclosure provide an ore sorting apparatus including:

the detection platform 1 comprises a plurality of ore containers 4 arranged in series, the ore containers 4 being used for containing ore 8 to be detected,

a detecting device arranged below or above the detecting platform 1 for classifying ores into different grades by detection, and each ore container 4 is correspondingly provided with a detecting device,

the receiving devices are arranged at two sides of the detection platform 1 and comprise at least two containing parts for containing ores with different grades,

the ore container 4 is rotatable in a direction approaching the receiving portion for moving the ore 8 in the ore container 4 into the corresponding receiving portion;

the distributing device comprises a plurality of conveying devices 7, wherein the conveying devices 7 are arranged in series and are arranged in one-to-one correspondence with the ore containers 4.

According to the ore sorting device provided by the embodiment of the disclosure, through arranging a plurality of ore containers in an in-line manner on the detection platform, the ore sorting device can be suitable for ore sorting under various conditions, such as a radioactive sorting mode, an infrared detection sorting mode and the like, and specifically, the ore can be detected by arranging different detection devices. In different cases, different types of detection devices are used for the detection of ores. For example, in the case of sorting uranium ores, a gamma ray detector may be employed as the detection means. In addition, in the embodiment of the disclosure, a plurality of conveying devices 7 are arranged as a distributing device, the conveying devices 7 are also in an in-line arrangement mode, the conveying devices 7 are in one-to-one correspondence with the ore containers 4, the plurality of ore containers 4 can be distributed at the same time, and the distributing work of one line of ore containers is completed at one time, so that the efficiency is high.

According to the ore sorting apparatus of the present disclosure, a plurality of ore containers 4 are provided in series on the detection platform 1, and the detection apparatus is provided above or below the respective ore containers 4, so that it is possible to correspond to different detection modes of the ore 8. For example, the ores 8 may be detected and sorted in batches after being placed in the respective ore containers 4 at one time. The solid angle between the detection device and the ore 8 is preferably as large as possible, whereby the time utilization efficiency of the ore sorting device is ensured, so that the detection sorting of the ore 8 is more efficient. Wherein, the space part surrounded by one conical surface is called a solid angle. For example, the spherical surface is a spherical surface of a detecting device arranged below the ore container 4, the length between the detecting device and the ore is a radius, and the ratio of the area of the cone intercepted by the spherical surface to the square of the spherical radius is the current solid angle. In the ore sorting apparatus of the present disclosure, the solid angle is pi/3 or more, preferably pi/2 or more, and more preferably pi or more.

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 each column may be identical or not identical.

Further, the plurality of ore containers 4 arranged in-line in the present disclosure may comprise a plurality of ore containers 4 arranged in an array, wherein the array is embodied as a rectangular array, i.e. a linear planar array of a plurality of rows and a plurality of columns. In response to this, the distributing device may be provided in an array, but a movable distributing device that distributes the material in one row or one line of the plurality of ore containers 4 provided in an array is preferable. In other words, the distributing device distributes only one row or one line of ore containers at a time, and distributes the ore containers of the next row or the next line after completing the distribution of the ore containers of the one row or one line, thereby sequentially completing the distribution of the ore containers 4 of all the rows or all the columns arranged in the array.

In the present disclosure, in the process of performing the detection and sorting of the ore 8, it is first required to move the ore 8 to the corresponding ore container 4 by the distributing device, then perform the corresponding detection in the ore container 4, and finally move the detected ore to the corresponding receiving device, thus comprising at least three steps of distributing, detecting and sorting. The placement and detection of ore 8 is performed according to the array-type arrangement of the plurality of ore containers 4 in the present disclosure, and the progress of ore detection per ore container 4 may not be exactly the same, and it is preferable that the ore containers 4 of each row or column are arranged to perform the same operation, and the operations are different between different rows or columns, compared to the structure of the single column arrangement of fig. 1 to 4. For example, in the case where five rows of ore containers 4 are arranged in an array, a set of movably arranged distributing devices sequentially distribute the ore containers 4 of each row, and when the distribution of the first row is completed, the distributing devices move to the second row to perform the distributing operation, and at the same time, the detection of the ore in the first row of ore containers 4 is started, and then the distributing devices sequentially move to the third, fourth and fifth rows to perform the distributing operation, for example, when the distributing devices perform the distributing operation in the fifth row, the detected ore 8 in the first row of ore containers 4 is sorted, so that the distribution, detection and sorting rolling of the ore sorting device can be circulated, and the detection efficiency is higher. Another advantage is that the number of receiving devices can be significantly reduced, for example, a single row of receiving devices may be placed in a certain two rows of ore containers 4, i.e. the number of receiving devices (row number) =row number of placement area+1.

The number of rows and columns of the ore containers 4 arranged in an array may be appropriately selected according to the time required for distribution, detection and/or sorting, and the like.

In one embodiment, a plurality of ore containers 4 arranged in series are provided in a rotatable structure, such as a drum rotatable about an axis. The circumferential side wall of the drum may be formed by a plurality of axially extending support plates arranged at intervals, each support plate being provided with an array of ore containers 4. Each support plate can be horizontally arranged, so that when the roller rotates, the support plates do not change the form of the horizontal arrangement of the support plates, ores are placed on the corresponding support plates, and the roller rotates to drive the support plates to rotate together with the ore structure above. The support plate may be regarded as a detection platform. In addition, each support plate may be provided with a hook portion or a hinge portion, through which each ore container 4 is connected with the support plate, and when the drum rotates, the ore container 4 is vertically suspended in the support plate by means of its own weight, i.e., in the course of the drum rotation, the ore container 4 may be kept horizontal all the time. The rotation of the ore container 4 when moving the ore to the receiving device can be accomplished by an auxiliary mechanism (e.g. a telescopic rod). The distributing device can be arranged above the roller so as to distribute the ore container at the highest position, and the receiving device can be arranged below the roller so as to accommodate the ore at the lowest position and finish detection. When the ore sorting device works, the ore container 4 on a certain supporting plate can be distributed, then the ore container 4 leaves the distributing device to start to be detected, the next supporting plate drives the ore container 4 to the lower part of the distributing device to be distributed through rotation, sorting is performed when the ore container 4 rotates to the lowest part of the roller, and the ore container falls into a corresponding receiving device to circulate. Therefore, the supporting plate on one roller can detect, distribute and sort simultaneously, and the detection efficiency is higher. The number of the support plates of the drum, the rotation speed, the arrangement position of the distributing device and the receiving device can be appropriately selected according to the required time for distributing, detecting and/or sorting, and the like.

Fig. 5 schematically shows a rotatable-drum basic structure, in which four support plates are provided on the drum. The inline ore container 4 is placed perpendicular to the paper surface. The distributing device (e.g., the conveying device) and the receiving device are not shown in fig. 5, but as described above, the arrangement positions of the distributing device and the receiving device may be appropriately selected according to the actual situation.

The ore sorting device is provided with the receiving device for accommodating ores of different grades, and comprises at least two accommodating parts for accommodating ores of at least two different grades, such as two grades of concentrate and lean ore. In one embodiment, the receiving device comprises a first silo 2 and a second silo 3, wherein the first silo 2 and the second silo 3 may be arranged on both sides of the detection platform 1, respectively. In the present disclosure, the number of bins may be adjusted according to the grade that the ore 8 is actually to distinguish. In this embodiment through setting up the ore container that can overturn to different directions in will surveying good ore removal to corresponding feed bin, the direction and/or the angle of control ore container upset are different, can fall different ores in the different feed bins.

In one embodiment, the receiving device is elongated and extends in the longitudinal or width direction of the detection platform 1.

Because the ore containers 4 on the detection platform provided by the disclosure are in an in-line type or an array type, after each row or each column of ore containers 4 are detected, the separated ores of different grades are also gathered together, preferably, two sides of each row or each column of ore containers 4 are provided with strip-shaped receiving devices, and one receiving device can be shared between the adjacent rows or adjacent columns of ore containers 4, and a plurality of receiving devices can be also arranged according to the situation.

Wherein, according to the ore sorting apparatus provided by the present disclosure, after the distribution and detection of the ore 8 to the ore container 4 are completed, the ore container 4 can be easily turned over in a direction approaching to the receiving portion, i.e., the direction of the first bin 2 or the direction approaching to the second bin 3. Taking fig. 2 and 4 as an example, the ore 8 easily falls to the left or right into the corresponding bin by turning over the ore container 4, and in this embodiment, a rotating shaft 5 (marked by a broken line in the figure) is preferably provided in the ore container 4 to rotate; in order to ensure the falling efficiency of the ore after overturning, the embodiment preferably sets the overturning angle of the ore container 4 to be 60-90 degrees each time, the inclination angle of the two side walls of the ore container to be 30-45 degrees (the inclination angle refers to the included angle between the side wall of the ore container 4 and the central axis of the container), the ore is smoothly overturned into the corresponding bin through the inclined side wall of the ore container 4, and the ore container 4 can realize the movement of the ore without overturning by an excessive angle, so that the time is saved.

In one embodiment, the bottom of each ore container 4 is provided with a pressure sensor for detecting the mass of the ore 8 to be detected.

In this embodiment, the pressure sensor for detecting the quality of ore is directly installed at the bottom of the ore container 4, and when the ore 8 is placed in the ore container 4 for detection, no relative motion exists between the ore 8 and the pressure sensor, so that the quality detection is accurate, and the false alarm rate can be reduced.

In one embodiment, a shielding partition 10 is provided between adjacent ore containers 4.

In this embodiment, in order to ensure the number of ores 8 to be detected at one time, the detection efficiency is increased, and the interval between adjacent ore containers 4 may be set smaller, i.e., the number of ore containers 4 may be increased for the same size of detection platform. In addition, shielding baffles 10 can be arranged between adjacent ore containers 4 to ensure that adjacent detection devices and adjacent ores 8 do not influence each other, so as to reduce or eliminate adverse effects of adjacent ores 8 when being detected. The shielding separator 10 may be a lead plate, a steel plate, or the like. In another embodiment, the shielding partition 10 is arranged movably and/or detachably on the surface of the detection platform 1, whereby the size of the individual ore containers 4 can be adjusted according to the actual requirements. Likewise, one or more detection devices arranged in correspondence with the ore container 4 may also be arranged movably and/or detachably.

As shown in fig. 1 to 4, the present embodiment provides an in-line type detection platform 1, and a plurality of ore containers 4 are provided on the detection platform 1 to detect, so that ores are transferred to corresponding detection positions by providing a conveying device 7, and preferably, one conveying device 7 is correspondingly provided on each ore container 4, so that each ore container 4 has an independent conveying device to transfer ores 8, and the respective conveying devices do not affect each other, and if a problem occurs in the detection of one ore container 4, the conveying device corresponding to the position and the position can be independently stopped to perform maintenance, and the detection of other ore containers 4 and the operation of the conveying device 7 do not affect any.

Preferably, a main conveyor and a plurality of sub conveyors can be further arranged, the plurality of sub conveyors correspond to different ore containers 4, the main conveyor can be connected with the sub conveyors, steering mechanisms are arranged at connection points, ores can be directly placed on the main conveyor without being distinguished, different ores are moved to different sub conveyors through the steering mechanisms, and then the ores are moved to the corresponding ore containers 4 (the main conveyor in the structure is not shown in the figure), so that the movement of the ores to be detected is more convenient.

The ore container 4 in the present disclosure may also be set in an array form, and the conveyor set above the ore container 4 set in the array may be set in a movable form, moving in the row direction or the column direction of the ore container 4, moving to the upper side of the corresponding ore container 4, and distributing the detection position below may be realized.

Further, the conveying end of each conveyor 7 is arranged above the corresponding ore container 4.

In this embodiment, the corresponding ore 8 is transferred into the ore container 4 of the detection platform 1 by the conveying device 7, preferably the tail end of the conveying device 7 is arranged above the corresponding ore container 4, so that the ore can fall into the ore container 4 accurately, or the tail end of the conveying device 7 is arranged near the upper part of the ore container 4 according to the moving speed of the conveying device 7, so long as the ore 8 on the conveying device 7 can be conveyed to the corresponding ore container 4.

In the present disclosure, the distributing device may also take other forms, such as gripping of the respective ore directly with a mechanical gripper, or moving of the ore with a movable net bag or the like, or distributing with a plurality of pipes, different pipes being connected to different ore containers 4.

When the ore sorting device in this embodiment is used, firstly, the ore 8 on the conveying device 7 falls into the ore container 4, the pressure sensor 6 at the bottom of the container detects the quality of the ore, and meanwhile, the detector arranged near the ore container 4 detects the ore to judge the condition of the ore, for example, whether the ore is concentrate or non-concentrate is judged according to the specific radioactivity of the ore 8, and then the ore is poured into the corresponding bin through the overturning of the ore container 4, so that the separation of the ores with different grades is realized.

In the above embodiments, there are provided various ore sorting apparatuses each having a pressure sensor 6 for detecting the mass of ore, capable of directly detecting the mass of ore 8. The pressure sensor 6 can be directly arranged below the ore container 4 of the detection platform 1, the ore 8 and the detection platform 1 do not move relatively, and the mass detection of the ore is more accurate. In addition, the ore sorting device adopting the in-line structure in the present disclosure can improve the detection efficiency of ores. For example, the detection judging time of radioactive ore is 0.8s, the time of distribution and unloading is about 0.1s, in the case that the ore sorting device is provided with 10 ore containers 4, the sorting of the ore 8 in the 10 ore containers 4 can be completed simultaneously, the distribution, detection, analysis and sorting operations of the ore can be circularly performed, and meanwhile, the time utilization rate of the detection device can reach 80%, so that the detection efficiency is greatly improved. In the case of using the array-type ore container 4, the operations of distributing, detecting, analyzing, and sorting the ores in the plurality of rows of ore containers 4 can be performed in batch, further improving the detection efficiency. It is noted that in the present disclosure, in the case of having a pressure sensor 6, the term "detection" includes detection by a detection means and mass detection by the pressure sensor 6, unless otherwise indicated.

The device that this embodiment provided can improve the time utilization efficiency of detector under the condition that ore charge and ore container upset occupy the time proportion low.

In an embodiment of the present disclosure, the ore sorting apparatus further comprises a control device which is in communication connection with the detection device, the ore container 4, the pressure sensor 6 provided on the detection platform 1, etc. When the ore is placed on the detection platform 1, in particular the ore container 4, the pressure sensor 6 detects the ore on the detection platform 1, the detection means also detect the ore at the same time, the detection result is sent to the control means, the control means calculates the content of a specific element in the ore based on the corresponding detection result, preferably in comparison with ore grade criteria pre-stored in a reservoir of the control means, thereby classifying the ore into different grades. When the ore detection is completed, the control device performs other structural operations (e.g., turning of the ore container 4) to move the detected ore into the receiving device.

Specifically, the control device is in communication connection with the ore container 4, and when the ore detection completion control device receives the detection result, the control device controls the ore container 4 to perform corresponding sorting actions, and different grades of ores are sent into corresponding accommodating parts, for example, the controller controls the ore container 4 to overturn in different directions, and corresponding ores fall into different bins.
