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.

And a cleaning mechanism 16 for cleaning the accumulated dust.

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.

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 13 is used for detecting ores at a preset 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 13 for detecting the ore at a predetermined position;

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 13 for detecting the ore at a predetermined position;

wherein the feeding mechanism 11 is located downhole;

one side of the transmission mechanism 12 close to the feeding mechanism 11 is arranged underground, and one side far away from the feeding mechanism 11 is arranged on the ground.

The conveyor means 12 here have the function of both transporting the ore from the feeder means 11 to a predetermined location and lifting the ore from the well to the surface.

In the embodiments provided herein, the mineral separator 100 is located at least partially downhole and at least partially at the surface. Therefore, all links of mineral separation can be prevented from being located on the ground, the underground working time of miners is shortened, and the production safety is improved.

Further, in a preferred embodiment provided by the present application, the cleaning mechanism 16 is disposed near the conveying mechanism for removing the dust accumulated on the conveying mechanism.

It will be appreciated that the cleaning process may improve the safety of the production process. And, in whole ore sorting process, the clearance process design has more beneficial effects near transmission device. For example, dust can be prevented from adhering to the conveying mechanism, and effective work of the conveying mechanism can be improved. The dust is removed in the transmission process, so that the dust can be prevented from being deposited near the detection mechanism to influence the detection precision of the detection mechanism, and the dust can be prevented from interfering the sorting process. Therefore, the cleaning mechanism 16 is disposed near the conveying mechanism, which is beneficial to the smooth production process.

Further, in a preferred embodiment provided herein, the cleaning mechanism 16 includes a scraper 161.

In an embodiment where this is achieved, the ore falls through the feeding mechanism into the transport mechanism. The dust is either suspended in the air or adheres to the ore and accumulates on the conveyor mechanism as the ore falls or slips. The scraper 161 is arranged near the conveying mechanism, so that dust adhered and accumulated on the conveying belt can be effectively scraped.

Further, in a preferred embodiment provided herein, the scraper 161 is disposed below the conveying mechanism.

It is understood that the scraper 161 is disposed below the conveying mechanism, and when the conveying belt is stuck with dust and falls down, the scraper 161 disposed below operates only when necessary, and can effectively scrape off the dust stuck and accumulated on the conveying belt. Meanwhile, the scraper 161 is arranged below the transmission mechanism, so that normal transmission operation is not interfered, and cleaning work can be finished by utilizing the self-circulation process of the transmission mechanism.

Further, in a preferred embodiment provided herein, the scraper 161 has a blade 1611 disposed opposite to the direction of the conveying mechanism.

It will be appreciated that the scraper 161 has a blade 1611 disposed opposite the direction of the conveyor, so that when the conveyor is running, a close contact is formed between the blade 1611 of the scraper 161 and the conveyor, effectively scraping off the dust collected on the conveyor. The conveying belt after dust adhesion is approximately U-shaped. The blade 1611 is disposed at the front end of the U-shape, and when the conveyor belt circulates, the vertical component of the conveyor belt that moves upward from the blade 1611 enhances the removal effect of the adhered dust.

Further, in a preferred embodiment provided by the present application, the scraper 161 has several scraping units distributed in a fish scale shape.

In the embodiment provided by the present application, the scraper 161 has several scraping units distributed in a fish scale. Through the scraping units distributed in a fish scale shape, multiple scraping operations can be performed, and dust on the conveying mechanism can be removed more effectively. It can be understood that the scraping units stacked layer by layer, the scraping units stacked outside can protect the masked scraping units, and the scraper 161 has a long life.
