Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, the present application discloses a mineral separator 100 including:

a feeding mechanism 11 for feeding ore;

a transport mechanism 12 for transporting the ore to a predetermined position after loading the ore from the feed mechanism 11;

a detection mechanism 13 for detecting the ore at a predetermined position;

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

wherein the conveying mechanism 12 is provided with a buffer device for buffering the ore jumping on the conveying mechanism 12.

And a lifting mechanism 15 for lifting qualified ore from the classified ore down hole to the surface.

The mineral separator 100 may have various shapes, and may be represented as a metal mineral separator 100 or a nonmetal mineral separator 100 in a specific scene. A metal mineral separator 100 such as iron ore, copper ore, antimony ore, and various rare earth metal ores, etc. A non-metallic mineral separator 100, such as a diamond ore, coal mine, or the like. The mineral separator 100 functions to separate mineral products rich in elements to be extracted from slag that is poor in the elements to be extracted. The mineral separator 100 screens out minerals rich in the elements to be extracted for further processing to form material data beneficial to human beings.

The feed mechanism 11 is used for feeding ore. The ore supplied by the feeding mechanism 11 may be a primary raw material or a raw material that has been previously processed. The primary raw material can be obtained directly from the mine by crushing or cutting. The raw material for the rough treatment may be obtained from the primary raw material by simple particle size screening, for example, by removing ores with too large and too small diameters to obtain ores with a particle size within a certain range. Specifically, the feeding mechanism 11 may be provided with a restriction tank, a funnel tank, a vibrating screen, a classifying screen, and the like to obtain ore materials according with expectations. It is understood that the specific form of the feeding mechanism 11 herein obviously does not constitute a limitation to the specific protection scope of the present application.

The transport mechanism 12 is used to transport the ore to a predetermined location after loading the ore from the feed mechanism 11. It will be appreciated that the transport mechanism 12 has a location to load ore. The position of the ore in the device can be understood as the initial position of the ore on the transport means 12. The setting of the ore loading position is related to the specific configuration of the conveying mechanism 12 and the feeding mechanism 11. In one practical embodiment provided herein, the feeding mechanism 11 may be a hopper trough, the transport mechanism 12 may be a conveyor belt, and the location where ore is loaded may be a location below the hopper trough that is directly opposite the conveyor belt. The predetermined position may be understood as a point along the path of the ore at the transport mechanism 12 or a location along the path. In the design concept of the mineral separator 100, the predetermined position is used for judging the mineral or ore rich in the element to be extracted and the slag or ore poor in the element 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 miniaturization of the conveyance mechanism 12 or restricts miniaturization of the mineral separator 100. When the ore has a relatively simple motion state at the preset position, the ore sorter 100 is beneficial to judging the ore.

In one embodiment provided by the present application, the transport mechanism 12 is provided with a buffer device 121 for buffering ore bouncing on the transport mechanism 12. Thus, the ore can be judged by the mineral separator 100 when the ore only moves in the conveying direction, or the ore is kept static relative to the conveying mechanism 12 at the preset position and does not move relative to the conveying mechanism 12 in the gravity direction, and the movement state of the ore at the preset position is relatively simple.

Further, in a preferred embodiment provided herein, the conveyor 12 has a ore loading position;

the buffer device 121 includes a roller disposed near the ore loading position of the conveyor 12.

It will be appreciated that the transport mechanism 12 may generally include a driving roller for driving movement and a driven roller for driven movement, and a conveyor belt mounted between the driving roller and the driven roller. In the embodiment provided herein, the buffer device 121 includes rollers disposed near the ore loading position of the transport mechanism 12. The ore loading position of the transport mechanism 12 is between the drive roller and the roller. Alternatively, the ore loading position of the transport mechanism 12 is between the driven roller and the roller. In this way, the rollers support the ore in conjunction with the drive or driven rollers and the conveyor belt. The impact force of ore falling on the conveying belt is resolved by a mechanism formed by the rollers, the driving roller and the conveying belt, or the impact force of ore falling on the conveying belt is resolved by a mechanism formed by the rollers, the driven roller and the conveying belt. In this way, the run-out of ore at the transport mechanism 12 can be buffered.

Further, in a preferred embodiment provided herein, the conveying mechanism 12 comprises a conveyor belt, the conveyor belt comprises a side facing the ore;

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

It will be appreciated that the further the rollers are located from the ore loading position of the conveyor mechanism 12, the greater the degree of belt deformation, which results in a greater contact area between the belt and the rollers, and the more significant the frictional heating phenomenon, which tends to significantly shorten the belt life. The closer the distance between the roller and the ore loading position of the conveying mechanism 12 is, the smaller the deformation degree of the conveying belt is, the less the buffering effect is, and the roller may be directly impacted by the ore, thereby affecting the service life of the roller. It has been determined through a number of tests that the spacing between the rollers and the ore loading location of the conveyor means 12 in the direction of ore transport is preferably between 1 and 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 herein, the buffer device 121 includes a cushion pad.

It will be appreciated that in this embodiment, buffering of ore against bouncing on the conveyor mechanism 12 is relied upon primarily. Compared with the method of buffering the ore jumping on the conveying mechanism 12 by using the deformation of the conveying belt, the service life of the conveying belt can be greatly prolonged.

the buffer pads are arranged on the opposite side of the ore facing side of the conveyor belt, extend in the ore conveying direction from the ore loading position of the conveying mechanism 12 and have a length of 1 to 5 times the diameter of the ore.

The cushions extend in the ore conveying direction from the ore loading position of the conveying mechanism 12, and the cushions are wasted when the cushions extend for a length longer than a certain range. When the extension length of the cushion pad is too short, the cushion pad and the conveyor belt share the impact force of ore loading to the conveying mechanism 12, so that the friction heating phenomenon is more obvious and easier as the contact area between the conveyor belt and the driving roller and the driven roller is larger, and the service life of the conveyor belt is obviously shortened. It has been determined through a number of tests that the cushions preferably extend 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 by the present application, the base of the conveying mechanism 12 is a woven fabric, and the side facing the ore is coated with wear-resistant rubber.

The base of the transfer mechanism 12 is a fabric to facilitate heat dissipation from the pores of the fabric. The side of the conveying mechanism 12 facing the ore is coated with wear-resistant rubber, so that the abrasion of the ore to the conveying mechanism 12 can be relieved. On one hand, the heat accumulation can be prevented from being aggravated to accelerate the abrasion of the transmission mechanism 12, on the other hand, the abrasion of the transmission mechanism 12 is relieved by using an abrasion-resistant material, and the problem that the service life of the transmission mechanism 12 is short is solved from two aspects.

And the detection mechanism 13 is used for detecting the ore at a preset position. In an implementable embodiment provided by the present application, mineral products rich in the element to be extracted are separated from slag poor in the element to be extracted using optical means. The detection mechanism 13 may use X-rays. The detection mechanism 13 may include an X-ray generation device and an X-ray detection device. The X-ray detection device can determine the enrichment degree of the elements to be extracted through optical phenomena such as transmission, diffraction and spectrum of X-rays, so that the separation of ores is carried out.

It will be appreciated that the detection mechanism 13 herein may be loaded with different identification or analysis models depending on the ore type to improve the efficiency and accuracy of ore sorting. For example, loading a recognition model for rare earth elements, loading a recognition model for coal mines or loading recognition models for different particle size ores, loading recognition models for different element enrichment concentrations.

Referring to fig. 12 and 13, the detection mechanism 13 disclosed in the present application includes:

a radiation source 131;

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

the detector 132 is arranged in the following manner:

several detectors 132 are distributed in the same plane as the radiation sources 131.

The detection mechanism 13 disclosed in the present application includes:

a radiation source 131;

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

the detector 132 is arranged in the following manner:

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

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

Further, the radiation source 131 is a point radiation source or a ring radiation source. It will be appreciated that different arrays of radiation sources 131 may transmit different types of energy detection beams. The probe beam may be continuous spectrum or characteristic spectrum. The probe beam may be high or low powered. The choice of which type of source and which type of energy detection beam to transmit can be determined based on the characteristics of the material rich in the mineral being examined. It can be understood that the detection beam of the ring-shaped ray source has higher energy than the point-shaped ray source due to the larger emitting area, and the energy generated is higher finally.

The detector 132 is configured to receive the radiation emitted from the radiation source 131, and analyze and identify the distribution and content of the specific element in the ore to be detected according to the received radiation emitted from the radiation source 131 after penetrating through the ore. The detector 132 may transmit the detection back to provide information for the next job.

The detector 132 is positioned in such a manner that a normal direction of the detector 132 passes through the radiation source 131. It is understood that X-rays travel along straight lines and are diffracted, reflected and refracted at the surface of a substance. The detector 132 mainly performs imaging by the transmitted and scattered spectral distribution of the ore to be detected irradiated by the X-ray, and further analyzes and identifies the distribution and content of the specific element in the ore to be detected. Therefore, the centers of the detectors 132 are on the same plane as the source 131, 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. Meanwhile, since the plurality of detectors 132 and the radiation sources 131 are distributed in the same plane, it is ensured that the radiation is incident on the detectors 132 in the vertical direction, the incidence rate of the radiation is increased, and the imaging quality is further improved.

Further, in a preferred embodiment provided in the present application, the detecting mechanism 13 further includes a linear mounting groove 133 and a board 134;

the detectors 132 are mounted on boards 134;

the board 134 is inserted into the mounting groove 133.

In one implementation, the detecting mechanism 13 further includes a linear mounting slot 133 and a board 134, the plurality of detectors 132 are mounted on the plurality of boards 134, and the board 134 is inserted into the mounting slot 133. The detector 132 is mounted on the plurality of boards 134, so that the related detection information can be conveniently accessed and transmitted through the preset interface, the boards 134 are embedded into the mounting grooves 133 and are mounted on the detection mechanism 13 through the mounting grooves 133, the boards 134 and the detector 132 can be conveniently dismounted and mounted, and the types and the number of the detector 132 can be flexibly configured according to the detection requirements. The higher the assembly accuracy between the board 134 and the mounting groove 133, the more satisfactory the concentricity of the detector 132 with respect to the radiation source 131. Thus, the structure in which the board 134 is fitted into the mounting groove 133 can improve the mounting accuracy of the detector 132 by virtue of the mounting accuracy between the board 134 and the mounting groove 133.

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

In an implementation provided by the present application, the mounting groove 133 is interference-fitted at one side and provided with an elastic pressing device 135 at the other side. The insertion and the removal of the board card 134 are facilitated through the interference matching mechanism on one side, and when the board card 134 is installed, the board card 134 is inserted, the elastic pressing device 135 is closed, and the board card 134 is fixed on the installation groove 133. When the board 134 is detached, the elastic pressing device 135 is opened, and the board 134 is taken out. The elastic pressing device 135 can facilitate the installation of the board card 134 on one hand, and on the other hand, only one side of the board card 134 matched with the installation groove 133 is required to have higher installation accuracy, so that the high-accuracy implementation cost is reduced.

Further, in a preferred embodiment provided herein, the linear mounting groove 133 is curved with an arc.

It can be understood that the distribution of the linear mounting grooves 133 is a curved shape with radian, so that all of the plurality of boards 134 mounted on the linear mounting grooves 133 and the centers of the plurality of detectors 132 mounted on the plurality of boards 134 can be on the same plane with the radiation source 131, thereby collecting the spectral distribution of the transmitted X-rays to a greater extent and improving the detection efficiency and accuracy. The curved linear mounting slot 133 ensures concentricity of the detector mounted to the board 134 when the board 134 is inserted.

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

Referring to fig. 15, further, in a preferred embodiment provided herein,

the detection mechanism 13 further comprises a board card 134;

the detectors 132 are mounted on boards 134;

a matching mechanism is arranged between two adjacent board cards 134, and meets the following conditions;

when the plurality of boards 134 are connected to each other by the connection mechanism between two adjacent boards 134, the plurality of boards 134 are arranged in an arc.

In the embodiment provided in the present application, the detecting mechanism 13 further includes a board 134, and the plurality of detectors 132 are mounted on the plurality of boards 134. And the access and transmission of the related detection information through the preset interface are facilitated. An adapting mechanism is provided between two adjacent boards 134, so that the boards 134 can be combined conveniently. When the plurality of boards 134 are connected to each other through the connection mechanism between two adjacent boards 134, the connection mechanism satisfies the condition that the plurality of boards 134 are arranged in an arc. Through the structure, the plurality of board cards 134 and the centers of the plurality of detectors 132 arranged on the plurality of board cards 134 can be on the same plane with the ray source 131, so that the spectral distribution of the transmitted X-rays is collected to a greater extent, and the detection efficiency and the detection precision are improved.

Further, in a preferred embodiment provided herein, the arc of the plurality of plate cards 134 arranged in an arc takes the radiation source 131 as a curvature center.

It can be understood that, the distribution mode that the arc lines of the plurality of board cards 134 arranged in an arc shape use the radiation source 131 as a curvature center can make all the normal directions of the plurality of detectors 132 installed on the plurality of board cards 134 pass through the radiation source 131, so that the spectral distribution of the transmitted X-rays is collected to a greater extent, and the detection efficiency and the detection accuracy are improved. The linear installation groove 133 takes the radiation source 131 as a curvature center, and the radiation emitted from the radiation source 131 reaches each detector 132 at the same time, thereby ensuring the imaging accuracy.

Further, in a preferred embodiment provided herein, the detector 132 may be mounted to a mounting;

the mounting base and the radiation source 131 are in a preset spatial position relationship to ensure that the normal direction of the detector 132 passes through the radiation source 131.

It should be noted that the mounting seat is understood to be the board 134. Alternatively, the mounting can be understood as an intermediate connection between the card 134 and the detector 132.

Further, in a preferred embodiment provided herein, the mounting seat is located on the detection mechanism 13.

Further, in a preferred embodiment provided by the present application, an adjusting device is disposed between the mounting base and the detector 132, so as to adjust the spatial position of the detector to reach that the normal direction of the detector passes through the radiation source.

The mounting is understood here to be an intermediate connection between the card 134 and the detector 132. Also, the intermediate connection device has an angle adjustment function to adjust the orientation of the detector 132 or the normal direction of the detector 132.

Further, in a preferred embodiment provided by the present application, the adjusting device is a sliding rail and a first blocking member cooperating with the sliding rail.

The guide direction of the slide rail here may be a circumferential direction or an axial direction. When the slide rail is adjusted in the circumferential direction, the circumferential distribution angle of the detector 132 with respect to the radiation source 131 can be adjusted. The coplanarity of the detector 132 with respect to the source 131 can be adjusted when the slide rail is adjusted in the axial direction. The first stop may limit the position of the detector 132 when adjusted to the appropriate position.

Further, in a preferred embodiment provided herein, the adjustment device includes an angle adjuster and a second blocking member defining the angle adjuster.

It is understood that the angle adjuster can directly adjust the orientation of the detector 132 or the normal direction of the detector 132 to correct the error of the detector 132.

Further, in a preferred embodiment provided herein, the detection mechanism further includes a mounting rail;

the normal direction of the mounting guide rail passes through the ray source.

In one embodiment provided herein, the mounting rail may be a linear mounting groove 133 with a curvature.

Referring to fig. 15, further, in a preferred embodiment provided in the present application, the two adjacent boards 134 are coupled by a groove or a bump.

It can be understood that, by the connection of the grooves and the bumps, the structure is simple and relatively low-cost, and the space occupied by the connection mechanism is saved, so that the assembly of the plurality of boards 134 is facilitated.

Further, in a preferred embodiment provided by the present application, the detection mechanism 13 further includes a board 134 and a board 134 positioning element;

the board 134 is mounted on the board 134 positioning element;

the board card 134 positioning part fixes the board card 134 and ensures the positioning accuracy of the board card 134.

It can be understood that the board 134 must be stably fixed on the detecting mechanism 13 to ensure that the board 134 and the detector 132 are distributed in the same plane as the radiation source 131, and the positioning accuracy of the board 134 directly affects the detection accuracy. Therefore, the board card 134 and the detector 132 need to be firmly fixed at a precise position by the board card 134 positioning element, so that the spectral distribution of the transmitted X-rays is better collected, and the detection efficiency and precision are improved.

Further, in a preferred embodiment provided herein, the detection mechanism can detect ore using at least a first energy probe beam and a second energy probe beam.

It is understood that ores contain different elements and different contents of elements. By analyzing different spectrums generated after detecting ores by different energy detection beams, the information of elements contained in the ores can be obtained. Accordingly, mineral products rich in the element to be extracted can be separated from slag poor in the element to be extracted using optical means. Because the ore often contains a plurality of elements to be extracted, the ore is detected by adopting a specific energy detection beam, and the mineral products rich in the specific elements to be extracted can be effectively screened out.

Further, in a preferred embodiment provided herein, the first energy probe beam faces a first element in the ore;

the second energy probe beam faces a second element in the ore.

In an implementation, the first energy probe beam is mainly directed to a first element in the ore to specifically identify whether the ore contains the first element and the abundance degree of the first element. Similarly, the second energy detection beam mainly faces to a second element in the ore to specifically identify whether the ore contains the second element and the content degree of the second element. In addition, according to different requirements of specific mineral product collection, other various energy detection beams can be adopted to specifically identify whether the mineral contains other required elements.

Further, in a preferred embodiment provided herein, the detection mechanism has a selection switch for selecting whether to use the first energy probe beam or the second energy probe beam.

It will be appreciated that the detection mechanism is provided with a selection switch to facilitate switching of the energy probe beam during operation. Meanwhile, different energy detection beams are switched according to different detection requirements through the selector switch, the reuse rate of the detection mechanism can be improved, and the design space is saved.

Further, in a preferred embodiment provided herein, the first energy probe beam and the second energy probe beam jointly face the first element.

In an embodiment that this application provided, jointly use through first energy detecting beam and second energy detecting beam and face first element jointly, can further improve imaging quality, more accurate, whether contain first element in the aimed identification ore to and the abundant degree of content of first element. In addition, according to different element distributions contained in specific mineral products, other multiple energy detection beam combination can be adopted, and whether the required specific elements are contained in the mineral ore or not can be identified more accurately and pertinently.

Further, in a preferred embodiment provided herein, the detection mechanism includes a radiation source;

a first detector for detecting a first probe beam of energy;

a second detector for detecting a second probe beam of energy;

In embodiments provided herein, the detection mechanism includes a source of radiation for emitting a probe beam. A first detector and a second detector are arranged in the ray emission direction and are respectively used for detecting the first energy detection beam and the second energy detection beam. And a filter positioned between the first detector and the second detector is arranged in the ray emission direction, and after the ray passes through the first detector, the first energy detection beam is filtered out by the filter, so that the second detector can more accurately detect the element distribution and content condition to be identified according to the second energy detection beam.

a second detector for detecting a second probe beam of energy;

the radiation source emits a first energy detection beam during a first clock pulse and a second energy detection beam during a second clock pulse.

In embodiments provided herein, the detection mechanism includes a source of radiation for emitting a probe beam. A first detector and a second detector are arranged in the ray emission direction and are respectively used for detecting the first energy detection beam and the second energy detection beam. The radiation source may automatically select the type of energy detection beam to emit based on the clock pulse. A first probe beam of energy is transmitted in a first clock pulse and a second probe beam of energy is transmitted in a second clock pulse. Through the time domain segmentation of the different energy detection beams, the detection can be more accurately carried out, and the crosstalk between the different energy detection beams is prevented.

Further, in a preferred embodiment provided herein, the detection mechanism includes a first radiation source for emitting a first energy probe beam;

a second radiation source for emitting a second energy detection beam;

a first detector for detecting a first probe beam of energy;

a second detector for detecting a second probe beam of energy.

In embodiments provided herein, the detection mechanism includes a first radiation source for emitting a first energy probe beam and a second radiation source for emitting a second energy probe beam. Different energy detection beams are emitted by different ray sources, so that the working efficiency of a ray emission link can be further improved, and delay of a single ray source in the process of switching emission beams is avoided. Meanwhile, different energy detection beams are emitted through different ray sources, so that different detection beams can be jointly used to face specific elements, the imaging quality is further improved, and more accuracy is achieved.

The embodiment of the application also provides a detection mechanism for the mineral product sorting machine, and the detection mechanism at least can adopt a first energy detection beam and a second energy detection beam.

In embodiments provided herein, the detection mechanism can employ at least a first probe beam of energy and a second probe beam of energy. The method comprises the steps of using detection beams with various energies to project and image the same detected object, comprehensively analyzing projection information of the detection beams with various energies to obtain information related to the specific attribute of the detected object, further analyzing the substance components and content according to the related information and a comprehensive identification algorithm, and identifying the type, the components and the characteristics of the detected object.

The sorting mechanism 14 is used for sorting and picking up the detection result of the ore according to the detection mechanism 13. The function of the sorting mechanism 14 is to separate the identified mineral products that are rich in the element to be extracted from the slag that is poor in the element to be extracted. Wherein the sorting mechanism 14 comprises a spraying device having at least two different fluid spraying modes for separating ore into at least three types.

Further, in a preferred embodiment provided herein, the injection device further comprises an actuating member 141;

the injection device has injection holes 142;

the actuating member 141 is circumferentially shielded at the injection hole 142 to change an area of the injection hole 142 to inject the fluid.

Referring to fig. 3 and 4, further, in a preferred embodiment provided in the present application, the actuating member 141 is a rod-shaped member;

in the first position, the actuating member 141 protrudes into the range covered by the injection hole 142;

in the second position, the actuating member 141 exits the range covered by the injection hole 142.

Specifically, for example, the injection hole 142 has a longitudinal section for injecting the fluid. A rod-shaped actuator 141 for shielding the longitudinal section is provided in the injection hole 142 or on the outer surface of the injection hole 142. In the first position, the actuating member 141 protrudes into the range covered by the injection hole 142; in the second position, the actuating member 141 exits the range covered by the injection hole 142. Thus, the injection holes 142 do not inject fluid, the injection holes 142 inject fluid without obstacles, the injection holes 142 inject fluid with obstacles, and three different movement modes, namely free falling of ore, impact of fluid on ore and impact of obstacle fluid on ore, can be separated into three.

Referring to fig. 5 and 6, further, in a preferred embodiment provided in the present application, the actuating member 141 is a mesh member;

in the first position, the deformation of the actuating member 141 partially overlaps with the range covered by the injection hole 142;

in the second position, the actuator 141 returns to a range not overlapping with the range covered by the injection hole 142.

Specifically, the actuator 141 is a variable parallelogram mesh, for example. In the first position, the actuator 141 deforms to partially overlap the range covered by the injection hole 142. Some sides of the parallelogram block the injection holes 142 with a longitudinal section that injects fluid. In the second position, the parallelogram returns to a square, rectangle, or does not overlap the range covered by the spray holes 142 when all sides of the parallelogram do not obstruct the spray holes 142 from having the longitudinal section of the sprayed fluid. Thus, the three different movement modes of free falling of ore, impact of fluid on the ore and impact of obstacle fluid on the ore can be separated into three types, wherein the fluid is not ejected from the ejection holes 142, the fluid is ejected from the ejection holes 142 without obstacle, and the fluid is ejected from the ejection holes 142 with obstacle.

the injection device has injection holes 142;

the actuating member 141 moves in the injection direction of the injection hole 142 to change the speed of the fluid injected from the injection hole 142.

The injection hole 142 has an injection longitudinal section through which the fluid is injected. When the movable element 141 is disposed in the injection hole 142, it may be located at a first hole depth position or a second hole depth position having a different distance from the injection longitudinal section. When the movable element 141 is located outside the injection hole 142, it may also be located at a first or second location outside the hole at a different distance from the injection longitudinal section. Thus, the injection holes 142 do not inject fluid, the injection holes 142 inject fluid at the first obstacle, and the injection holes 142 inject fluid at the second obstacle, so that three different movement modes, namely, ore free falling, impact of the first obstacle fluid on the ore, and impact of the second obstacle fluid on the ore, can be separated into three.

Referring to fig. 7 and 8, further, in a preferred embodiment provided by the present application, the injection device further includes an actuating member 141;

the injection device has injection holes 142;

the actuating member 141 is pivotable or translatable to change the direction in which the fluid is ejected from the ejection holes 142.

Specifically, when the actuating member 141 pivots to the first angle and the second angle, the impact force of the jetting fluid on the ore is different. For example, when the fluid is ejected from the ejection holes 142 at an upward angle of 45 degrees with respect to the gravity direction, or when the fluid is ejected from the ejection holes 142 at an upward angle of 60 degrees with respect to the gravity direction, the impact force of the ejected fluid on the ore is different. Therefore, three different motion modes of free falling of ores, impact of the ores by the fluid in the first spraying direction and impact of the ores by the fluid in the second spraying direction can be separated into three.

the sorting mechanism is at least capable of accessing fluid at a first pressure and a second pressure;

the actuator 141 moves to selectively engage fluid at a first pressure or to selectively engage fluid at a second pressure.

For example, the actuator 141 may be used as a fluid selection switch to selectively connect a fluid at a first pressure or a fluid at a second pressure. Thus, three different motion modes of free falling of ore, impact of the ore by the first pressure fluid and impact of the ore by the second pressure fluid can be separated into three.

Further, in a preferred embodiment provided herein, the injection device has an injection hole 142;

the mineral classifier can select different opening numbers of the injection holes 142 or injection opening periods of the injection holes 142.

The mineral classifier can select different opening numbers of the injection holes 142 or injection opening periods of the injection holes 142. Three different motion modes of ore free falling, ore fluid impact by the first number of injection holes 142 and ore fluid impact by the second number of injection holes 142 can be separated into three. Alternatively, the ore can be separated into three types, free fall, impact of the ore with a first duration fluid, and impact of the ore with a second duration fluid.

Further, in a preferred embodiment provided herein, the injection hole 142 has a first aperture and a second aperture;

the mineral separator may selectively open the injection holes 142 of the first aperture or selectively open the injection holes 142 of the second aperture.

The mineral classifier can selectively open the injection holes 142 of the first aperture or selectively open the injection holes 142 of the second aperture. Three different motion modes of ore free fall, ore fluid impact by the injection holes 142 with the first aperture and ore fluid impact by the injection holes 142 with the second aperture can be separated into three.

The injection device has at least two different fluid injection modes so as to separate the ore into at least three types. Therefore, the mineral product sorting machine can screen out three kinds of ores with different concentrations of the elements to be extracted at one time, and the production efficiency is improved.

In one implementation provided herein, the sorting mechanism 14 comprises an air jet, a liquid jet, or a robot.

The ore is disengaged from the transport mechanism 12 after continued movement after the transport mechanism 12 has passed the predetermined position. The sorted pick-up may be performed for the identified ore before or during the disengagement of the ore from the transport mechanism 12.

For example, the flight path of ore as it exits from the conveyor 12, and thus the drop point of ore, may be varied by means of a jet device during the exit of ore from the conveyor 12. It can be understood that the gas injection device can realize the separation of ores meeting the conditions only by configuring compressed gas, and the realization cost is low.

For example, the flight path of ore as it exits from the conveyor 12, and thus the drop point of ore, may be varied by a liquid spraying device during the exit of ore from the conveyor 12. It can be understood that the liquid spraying device needs to be provided with pressure liquid, so that the realization cost is high, but the ore can be cleaned, and the convenience is brought to the subsequent treatment of the ore.

For example, a robot may be used to pick up ore that meets the conditions before it is detached from the conveyor 12. It can be understood that the ore meeting the conditions is picked up by the mechanical arm, so that the realization cost is high, but the ore is classified finely, so that convenience is brought to the subsequent treatment of the ore.

Further, in a preferred embodiment provided herein, the sorting mechanism 14 comprises an air or liquid spraying device;

the mineral separator 100 further includes a second mineral conveying device for conveying the separated mineral.

When the falling position of the sorted ore satisfying the condition and the position to be processed next are spatially isolated from each other, the second ore transfer device may be used to transfer the sorted ore, thereby improving the production efficiency.

the mineral separator 100 also includes a backfill device to convey the slag.

It is understood that the ore material is likely to cause mine collapse after being removed from the mine. For safety reasons, in this embodiment the mineral separator 100 is also provided with a backfilling device to deliver slag to the point of extraction of the mineral material.

In the embodiment provided herein, the transport mechanism 12 is used to transport ore to a predetermined location after loading ore from the feed mechanism 11; the detection mechanism 1313 is used for detecting ore at a predetermined position; the transport mechanism 12 is provided with a buffer device 121 for buffering the run-out of the ore in said transport mechanism 12. In this way, the buffer device 121 can buffer the run-out of the ore on the conveyance mechanism 12 as much as possible, and therefore, the length of the conveyance mechanism 12 in the conveyance direction can be made as small as possible, and the mineral separator 100 can be easily miniaturized.

The lifting mechanism 15 is used to lift qualified ore from the sorted ore down hole to the surface.

Referring to fig. 9, further, in a preferred embodiment provided herein, the lifting mechanism 15 includes an endless conveyor belt;

the circulation conveyer belt is integrally provided with a hopper 151 for accommodating ores.

The endless conveyor belt integrally provided with the hopper 151 for receiving ore is mainly used to lift qualified ore from the underground to the ground. Of course, the endless conveyor belt may be driven by a motor. One side of the circulating conveyor belt close to the sorting mechanism is arranged underground, and one side of the circulating conveyor belt far away from the sorting mechanism is arranged on the ground. The endless conveyor may also be provided with a plurality of turning rollers for changing the specific direction of travel of the endless conveyor. For example, the hopper 151 integrated with the endless conveyor belt in the embodied process may be horizontally advanced and then vertically lifted. The hopper 151 integrally provided with the circulating conveyor belt can be lifted obliquely first and then lifted vertically. The circulating conveyer belt can be flexibly arranged according to the requirements of a production site.

Further, in a preferred embodiment provided herein, the lifting device comprises an endless conveyor belt;

a hopper 151 for receiving ore that can be suspended from the endless conveyor.

Unlike the previous solution, here the hopper 151 housing the ore can be suspended to an endless conveyor belt. That is, the hopper 151 is separable from the endless conveyor so that the hopper 151 is removed from the endless conveyor to dump the ore stored in the hopper 151.

Referring to fig. 10, further, in a preferred embodiment provided herein, the lifting mechanism 15 includes a guide rail 152;

a hopper car 153 moving on the guide rail 152.

It will be appreciated that the endless conveyor belt of the previous embodiment may operate continuously, or in a step-wise cycle. The guide rail 152 here is mainly used for reciprocating operation. When the hopper car 153 is full or the hopper car 153 receives ore up to a predetermined capacity, the hopper car 153 lifts the ore to the ground under the guide of the guide rail 152.

Further, in a preferred embodiment provided herein, the guide rail 152 includes a first guide rail 152 guiding the hopper car 153 in a first direction and a second guide rail 152 guiding the hopper car 153 in a second direction. From the sorting mechanism to the ground, a plurality of guide rails 152 and corresponding guide directions may be provided to improve production efficiency.

Further, in a preferred embodiment provided herein, at least one of the first guide rail 152 and the second guide rail 152 is used for lifting the hopper car 153 to the ground. At the actual production site, at least one of the first rail 152 and the second rail 152 is used to lift the hopper car 153 to the ground. The hopper car 153 may be lifted to the ground and then the hopper car 153 may be guided into position. The hopper car 153 may be guided to a proper position and then lifted vertically to the ground. Of course, horizontal guidance, inclined guidance or vertical guidance is possible, which combination is completely dependent on the arrangement at the production site.

Further, in a preferred embodiment provided herein, the first direction or the second direction is a vertical direction.

Further, in a preferred embodiment provided herein, the first direction is a horizontal direction; the second direction is a vertical direction.

It will be appreciated that in order to make the production site construction as simple as possible, the first direction may be arranged as a horizontal direction and the second direction as a vertical direction. The guide rail 152 extends continuously from the mined location to the pending mining location, which may be horizontal. The hopper car 153 may be lifted to the ground from a fixed position in the horizontal direction, and the amount of work required when the mining position changes can be reduced as much as possible.

Referring to fig. 11, there is further provided a mineral separator 100, including:

a feeding mechanism 11 for feeding ore;

a detection mechanism 1313 for detecting ore at a predetermined position;

a sorting mechanism 14 for sorting and picking up the detection result of the ore according to the detection mechanism 1313;

wherein the sorting mechanism 14 further comprises a lifting device for lifting qualified ore from the sorted ore down hole to the surface.

Where the lifting device is part of the sorting mechanism 14, the ore sorting process is combined with a lifting process in which the ore is lifted from the well to the surface.

This solution is particularly suitable for situations where the proportion of ore that meets the conditions is relatively low.

Further, the present application also provides a mineral separator 100, comprising:

a feeding mechanism 11 for feeding ore;

a detection mechanism 1313 for detecting ore at a predetermined position;

wherein the feeding mechanism 11 is located downhole;
