Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Please refer to FIG. 1 , the mineral sorting machine 100 disclosed in the present application includes:

Feeding mechanism 11 for supplying ore;

The conveying mechanism 12 is used to transport the ore to a predetermined position after loading the ore from the feeding mechanism 11;

The detection mechanism 13 is used to detect the ore at a predetermined position;

The sorting mechanism 14 is used for sorting and picking up the ore according to the detection result of the detection mechanism 13;

Wherein, the transmission mechanism 12 is provided with a buffer device for buffering the beating of the ore in the transmission mechanism 12 .

The lifting mechanism 15 is used for lifting qualified ores from the underground to the surface of the classified ores.

The mineral mineral sorting machine 100 may have various forms, and in a specific scenario, it may be expressed as a metal mineral mineral sorting machine 100 and a non-metal mineral mineral sorting machine 100 . Metal ore sorting machine 100, such as iron ore, copper ore, antimony ore and various rare earth metal ore. Separating machine 100 for non-metallic minerals, such as diamond mines, coal mines, and the like. The function of the mineral separator 100 is to separate minerals rich in elements to be extracted from slag depleted in elements to be extracted. The mineral sorting machine 100 screens minerals rich in elements to be extracted for further processing to form material data beneficial to human beings.

The feeding mechanism 11 is used for feeding ore. The ore supplied by the feeding mechanism 11 may be a primary raw material or a pre-processed raw material. Primary raw materials can be obtained directly from mines by crushing or cutting. Rough processing raw materials can be obtained from primary raw materials through simple particle size screening, for example, ore with too large and too small diameters is excluded to obtain ore with a particle size within a certain range. Specifically, the feeding mechanism 11 may be provided with restriction grooves, funnel grooves, vibrating screens, grading screens and other mechanisms to obtain ore raw materials that meet expectations. It can be understood that the specific form of the feeding mechanism 11 here obviously does not limit the specific protection scope of the present application.

The conveying mechanism 12 is used to transport the ore to a predetermined position after loading the ore from the feeding mechanism 11 . It will be appreciated that the transfer mechanism 12 has a location for loading ore. The position of the device ore can be understood as the initial position of the ore on the conveying mechanism 12 . The setting of the position for loading ore is related to the specific form of the conveying mechanism 12 and the feeding mechanism 11 . In an achievable embodiment provided by the present application, the feeding mechanism 11 may be a funnel trough, the conveying mechanism 12 may be a conveyor belt, and the position for loading ore may be a position under the funnel trough facing the conveyor belt. The predetermined position can be understood as a point or a position that the ore must pass through in the path of the conveying mechanism 12 . In the design idea of the mineral sorting machine 100, the predetermined position is used to determine minerals or ores that are rich in elements to be extracted and slag or ores that are poor in elements to be extracted for subsequent processing. The distance or length between the position where the ore is loaded and the predetermined position is a condition that restricts the miniaturization of the conveying mechanism 12 or the miniaturization of the mineral sorting machine 100 . When the movement state of the ore at the predetermined position is relatively simple, it is beneficial for the mineral sorting machine 100 to determine the ore.

In an embodiment provided in the present application, the transmission mechanism 12 is provided with a buffer device 121 for buffering the beating of the ore in the transmission mechanism 12 . In this way, the ore only moves in the conveying direction, or, in other words, the ore remains stationary relative to the conveying mechanism 12 at the predetermined position, and there is no movement relative to the conveying mechanism 12 in the direction of gravity. The sorting machine 100 determines the quality of the ore.

Further, in a preferred embodiment provided by this application, the conveying mechanism 12 has a position for loading ore;

The buffer device 121 includes rollers, and is disposed near the position of the conveying mechanism 12 where the ore is loaded.

It can be understood that the transmission mechanism 12 may generally include a driving roller that is actively moving and a passive roller that is driven to move, and a transmission belt spanned between the driving roller and the passive roller. In the embodiment provided by the present application, the buffer device 121 includes a roller disposed near the position of the conveying mechanism 12 where the ore is loaded. The ore loading position of the transport mechanism 12 is located between the drive rollers and the rollers. Alternatively, the ore loading position of the conveyor 12 is located between the passive roller and the roller. In this way, the rollers support the ore together with the drive or driven rollers and the conveyor belt. The impact force of the ore falling into the conveyor belt is resolved by the mechanism formed by the rollers, driving rollers and the conveyor belt, or the impact force of the ore falling into the conveyor belt is resolved by the mechanism formed by the rollers, the passive roller and the conveyor belt. In this way, the bouncing of the ore in the conveying mechanism 12 can be buffered.

Further, in a preferred embodiment provided by this application, the conveying mechanism 12 includes a conveying belt, and the conveying belt includes a side facing the ore;

The rollers are arranged on the opposite side of the conveyor belt facing the ore, and the distance between the rollers and the ore loading position of the conveyor mechanism 12 in the ore conveying direction is 1 to 5 times the diameter of the ore.

It can be understood that, the farther the distance between the setting position of the roller and the ore loading position of the conveying mechanism 12, the greater the degree of deformation of the conveyor belt, resulting in the larger the contact area between the conveyor belt and the roller, the greater the frictional heat generation phenomenon. Obviously, the life of the conveyor belt is significantly shortened. The closer the distance between the setting position of the rollers and the ore loading position of the conveying mechanism 12, the smaller the deformation of the conveyor belt, the less obvious buffering effect, and the rollers may be directly impacted by the ore, which will affect the life of the rollers. After many experiments, it is determined that the distance between the roller and the position of the conveying mechanism 12 for loading the ore in the ore conveying direction is preferably 1 to 5 times the diameter of the ore. The ore diameter here is the maximum value of the ore particle size range.

Further, in a preferred embodiment provided in this application, the buffer device 121 includes a buffer pad.

It can be understood that, in this embodiment, the buffer pad is mainly used to buffer the ore jumping in the conveying mechanism 12 . Compared with the aforementioned use of the deformation of the conveyor belt to buffer the beating of the ore in the conveyor mechanism 12, the service life of the conveyor belt can be greatly improved.

The buffer pad is arranged on the opposite side of the side of the conveyor belt facing the ore, and the buffer pad extends in the ore transport direction from the position of the transport mechanism 12 where the ore is loaded, and the length of the extension is 1 of the ore diameter. to 5 times.

The buffer pad extends from the position of the conveying mechanism 12 where the ore is loaded in the ore conveying direction. When the extension length of the buffer pad exceeds a certain range, the longer the buffer pad is, the waste of the buffer pad will be caused. When the extension length of the buffer pad is too short, the buffer pad and the conveyor belt jointly bear the impact force of loading the ore to the transmission mechanism 12, resulting in the larger the contact area between the conveyor belt and the driving roller and the passive roller, the more obvious the frictional heat generation phenomenon is. As a result, the life of the conveyor belt is significantly shortened. After many tests, it is determined that the length of the buffer pad should be 1 to 5 times the diameter of the ore. The ore diameter here is the maximum value of the ore particle size range.

Further, in a preferred embodiment provided in this application, the base of the transmission mechanism 12 is a woven fabric, and the side facing the ore is coated with wear-resistant rubber.

The base of the transmission mechanism 12 is a braided fabric, which facilitates heat dissipation from the pores of the braided fabric. The side of the conveying mechanism 12 facing the ore is coated with wear-resistant rubber, which can relieve the wear of the conveying mechanism 12 caused by the ore. On the one hand, it can prevent heat accumulation from aggravating and accelerate the wear of the transmission mechanism 12 , and on the other hand, use wear-resistant materials to alleviate the wear of the transmission mechanism 12 .

The detection mechanism 13 is used to detect the ore at a predetermined position. In an achievable embodiment provided by the present application, optical means are used to separate the minerals rich in the elements to be extracted and the slag depleted in the elements to be extracted. The detection mechanism 13 may use X-rays. The detection mechanism 13 may include an X-ray generating device and an X-ray detecting device. The X-ray detection device can determine the enrichment degree of the element to be extracted through optical phenomena such as X-ray transmission, diffraction, and spectrum, so as to perform ore sorting.

It can be understood that the detection mechanism 13 here can load different identification or analysis models according to different types of ore, so as to improve the efficiency and accuracy of ore sorting. For example, load identification models for rare earth elements, load identification models for coal mines, or load identification models for ores with different particle sizes, and load identification models for different element enrichment concentrations.

Please refer to FIG. 12 and FIG. 13 , the detection mechanism 13 disclosed in this application includes:

ray source 131;

receiving a plurality of detectors 132 from the radiation source 131;

The detectors 132 are arranged in the following manner:

A plurality of detectors 132 and the radiation source 131 are distributed in the same plane.

The detection mechanism 13 disclosed in this application includes:

ray source 131;

a detector 132 for receiving radiation from the radiation source 131;

The detectors 132 are arranged in the following manner:

The normal direction of the crystal of the detector 132 passes through the radiation source 131 .

Although the illustration of the ore is omitted in FIG. 12 and FIG. 13 , it is understood that the radiation source 131 is suspended above the ore, and the detector 132 receiving the radiation from the radiation source 131 is disposed below the ore. Thereby, the detector 132 detects the mineral element inside the ore by receiving the radiation transmitted through the ore.

In addition, as mentioned above, several detectors 132 and the radiation source 131 are distributed in the same plane. Specifically, by arranging the plurality of detectors 132 and the radiation sources 131 in the same plane, the radiation from the same radiation source 131 can be received by the plurality of detectors 132 , and the number of radiation sources 131 can be reduced. Also, the planes on which the plurality of detectors 132 and the radiation sources 131 are located are perpendicular to the traveling direction of the ore. That is, when the traveling direction of the ore is defined as the Y direction and the width direction of the transport mechanism 12 is defined as the X direction, the radiation source 131 is installed above the traveling ore, and the plurality of detectors 132 are installed on the traveling ore below, and a plurality of detectors 132 are arranged in the X direction. Thus, when the ore travels to a predetermined position, it is irradiated with radiation from the radiation source 131 above the ore, and a certain detector 132 of the plurality of detectors 132 below the ore receives the radiation that has penetrated the ore, thereby detecting Mineral elements in ore. Since the plurality of detectors 132 are arranged in the X direction, the rays after transmitting the ore arranged in the X direction on the transport mechanism 12 are received by the corresponding detectors 132 .

In addition, by passing the normal direction of the crystal of the detector 132 through the radiation source 131, it is possible to ensure the reception of radiation by the detector 132. Here, a plurality of detectors 132 arranged in the X direction may be arranged in an arc-like arrangement so that the normal direction of the crystal of each detector 132 passes through the radiation source 131 . That is, in a plane where the radiation source 131 and the plurality of detectors 132 are located, the plurality of detectors 132 are arranged in a circular arc, and the center of the circular arc overlaps with the radiation source 131 .

In addition, a plurality of detectors 132 arranged in the X direction can also be arranged in a linear arrangement, and by adjusting the inclination angle of each detector 132, the normal direction of the crystal of each detector 132 can pass through the radiation source 131 . In this case, an angle adjustment device needs to be provided for each detector 132 .

The ray source 131 is used for emitting detection rays, and an X-ray emitting device can usually be used in a specific implementation process. The energy supply mode of the detection wave speed emitted by the ray source 131 may be the single-energy X-ray source 131 or the dual-energy X-ray source 131 . The radiation source 131 can be a portable installation or a fixed installation. In a specific scenario, the corresponding ray source 131 is selected according to the characteristics of the ore to be detected.

Further, the ray source 131 is a point ray source or a ring ray source. It can be understood that different arrays of radiation sources 131 can send different types of energy detection beams. The probe beam can be either continuous spectral or characteristic spectral. The sounding beam can be high energy or low energy. What type of ray source to choose and what type of energy detection beam to send can be determined according to the characteristics of the substances rich in the minerals to be inspected. It can be understood that the detection beam of the ring-shaped ray source has a larger emission area than the point-shaped ray source, so the energy is higher, and the final energy is higher.

The detector 132 is used for receiving the radiation emitted by the radiation source 131, and analyzes and identifies the distribution and content of specific elements in the ore to be detected according to the received radiation emitted by the radiation source 131 after penetrating the ore. The detector 132 may transmit the detection results back to provide information for further operations.

The positions of the detectors 132 are arranged in such a manner that the normal direction of the detectors 132 passes through the radiation source 131 . It is understandable that X-rays travel in straight lines, diffracting, reflecting and refracting on the surface of matter. The detector 132 performs imaging mainly through the X-rays irradiating the ore to be detected with the spectral distribution of transmission and scattering, and then analyzes and identifies the distribution and content of specific elements in the ore to be detected. Therefore, the centers of the plurality of detectors 132 and the radiation source 131 are on the same plane, so that the spectral distribution of the transmitted X-rays can be collected to the maximum extent, and the detection efficiency and accuracy can be improved. At the same time, since the several detectors 132 and the ray source 131 are distributed in the same plane, it can ensure that the ray enters the detector 132 in a vertical direction, thereby improving the incidence rate of the ray, thereby improving the imaging quality.

Further, in a preferred embodiment provided in this application, the detection mechanism 13 further includes a linear installation groove 133 and a board card 134;

the plurality of detectors 132 are mounted on the plurality of boards 134;

The board 134 is inserted into the installation slot 133 .

The detector 132 is installed on several boards 134 to facilitate access and transmission of relevant detection information through a preset interface. The detector package is embedded in the installation slot 133 and installed on the detection mechanism 13 through the installation slot 133, which is convenient for the board 134 and the The detector 132 can be disassembled and assembled, and the type and quantity of the detector 132 can be flexibly configured according to the detection requirements. The higher the assembly precision between the detector package and the mounting groove 133 is, the better the concentricity of the detector 132 with respect to the radiation source 131 is required. Therefore, the structure in which the board 134 is embedded in the installation groove 133 can improve the installation accuracy of the detector 132 by means of the installation accuracy between the detector package and the installation groove 133 .

Further, one side of the mounting groove 133 is interference-fitted, and the other side is provided with an elastic pressing device 135 .

In an achievable embodiment provided by the present application, one side of the installation groove 133 is interference-fitted, and the other side is provided with an elastic pressing device 135 . The interference fitting mechanism on one side facilitates the insertion and removal of the detector package. When the detector package is installed, insert the detector package, close the elastic pressing device 135, and fix the detector package in the installation slot 133. superior. When the detector package is disassembled, the elastic pressing device 135 is opened, and the detector package is taken out. On the one hand, the elastic pressing device 135 can facilitate the installation of the detector package, and on the other hand, only the side of the detector package matched with the mounting groove 133 can be required to have higher installation accuracy, thereby reducing the cost of realizing high precision.

Further, in a preferred embodiment provided in this application, the linear installation groove 133 is a curved shape with an arc.

It can be understood that the distribution of the linear installation grooves 133 is a curve with an arc, so that all the several detector packages installed on the linear installation grooves 133 and the several detector packages installed in the several detector packages can be detected. The center of the detector 132 can be on the same plane as the radiation source 131, so that the spectral distribution of the transmitted X-rays can be collected to a greater extent, and the detection efficiency and accuracy can be improved. The curved linear mounting groove 133 can ensure the concentricity of the detector mounted on the board 134 when the detector package is inserted. Thus, by providing the arc-shaped mounting grooves 133 , a plurality of arc-shaped arrangements of the holding period 132 can be realized.

Further, in a preferred embodiment provided in the present application, the linear installation groove 133 takes the ray source 131 as the center of curvature. It can be understood that the linear installation slot 133 takes the radiation source 131 as the center of curvature, so that all the boards 134 installed on the linear installation slot 133 and the detectors 132 installed on the boards 134 The normal direction of the X-ray can pass through the ray source 131, so that the spectral distribution of the transmitted X-rays can be collected to a greater extent, and the detection efficiency and accuracy can be improved. The linear installation groove 133 takes the radiation source 131 as the center of curvature, and the radiation emitted by the radiation source 131 reaches each detector 132 at the same time, thereby ensuring the imaging accuracy.
