The mineral product sorting machine can comprise a feeding mechanism for continuously supplying ores, a conveying mechanism for conveying the ores to a preset position, a detecting mechanism for detecting the ores at the preset position, and a sorting mechanism for sorting and picking according to the detection results of the detecting mechanism on the ores.

In the process of realizing the prior art, the inventor finds that:

and after the conveying mechanism loads the ore from the feeding mechanism, the ore vibrates in the gravity direction in the process of being conveyed to the preset position. I.e. the ore is vibrated on the conveyor belt of the conveying mechanism in the gravity direction. The buffer device of the conveying belt is generally of a carrier roller type and a supporting plate type. When the bearing roller was as buffer, because of its cylindric surface, the conveyer belt can take place to sink when bearing, influences the steady transportation of ore, has reduced the transmission efficiency of mineral products sorter.

When the pallet is used as a buffer device, there are generally metal pallets and high polymer wear-resistant pallets. The metal supporting plate is generally 304 wiredrawing stainless steel, and the high-molecular wear-resistant supporting plate is generally a polyurethane buffer bed. The two supporting plates have independent bearing capacity and friction with a belt in the conveying process of the conveying belt, so that stable operation of ores is influenced, and the conveying efficiency of the mineral product sorting machine is reduced.

Therefore, a buffer device with strong buffering capacity needs to be provided, so that the mineral separator can run stably, and the transmission efficiency of the mineral separator can be improved.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to 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 obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Referring to fig. 1, a mineral separator 100 is disclosed for the present application, comprising:

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 transfer mechanism 12 is provided with a buffer device 121 comprising: at least two buffer bars 1211; a buffer holder 1212 on which the buffer strip 1211 is placed; a locking device 1213 for fixing the buffer strip 1211 to the buffer bracket 1212.

The mineral separator 100 can have various forms, and can 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, a coal mine, or the like. The mineral separator 100 functions to separate mineral products rich in the 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 humans.

The buffer device 121 in the mineral sorting machine shown in fig. 1 is a pallet type, and the buffer device 121 in the mineral sorting machine shown in fig. 2 is an idler type. In a preferred embodiment provided by the present application, the structure of the pallet-type buffer device 121 is optimized, so as to improve the transmission efficiency of the mineral product sorter transmission mechanism 12.

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 limiting tank, a funnel tank, a vibrating screen, a classifying screen, and other mechanisms to obtain ore materials meeting 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 loading of ore may be understood as the initial position of ore on the transport mechanism 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 or a location along the path of the ore at the transport mechanism 12. 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 location where the ore is loaded and the predetermined location is a condition that restricts the transport mechanism 12 from being miniaturized or restricts the mineral separator 100 from being miniaturized. 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, 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, but does not move relative to the conveying mechanism 12 in the gravity direction, the movement state of the ore at the preset position is relatively simple, and the ore sorting machine 100 is favorable for judging the ore.

The buffer device 121 includes: at least two buffer bars 1211; a buffer holder 1212 on which the buffer strip 1211 is placed; a locking device 1213 for fixing the buffer strip 1211 to the buffer bracket 1212.

Specifically, as shown in fig. 3, the buffer device 121 is mounted to the buffer holder 1212 by at least two buffer strips 1211 through a locking device 1213. As can be seen from the figure, both ends of the buffering strip 1211 are placed on the buffering holder 1212, and then both ends of the buffering strip 1211 are fixed to the buffering holder 1212 by the locking means 1213. The buffering strip 1211 is a suspended portion except two ends of the buffering strip which are fixed on the buffering bracket 1212. In a preferred embodiment provided by the present application, the suspended portion of the buffer strip 1211 in the buffer device 121 is used to independently carry the weight of the ore conveyed by the conveyor belt and the ore sorter.

It should be noted that the specific number of the buffering strips 1211 in the buffering device 121 can be installed on the buffering holder 1212 according to practical situations. For example, when the ore of the feeding mechanism 11 in the mineral product sorting machine only needs to be installed with two buffer strips 1211 in parallel on the buffer bracket 1212 or installed at a position spaced by one buffer strip 1211 to play a role of buffering by the buffer device 121, the two buffer strips 1211 need to be installed; if more than two buffer strips 1211 are needed for buffering the conveyer belt of the conveying mechanism 12 in the mineral product sorting machine, the buffer strips 1211 can be arranged in sequence or at certain intervals according to the number of the buffer strips 1211 capable of being arranged on the buffer bracket 1212 of the buffer device 121.

It is understood that the number of the buffer rods 1211 that can be mounted on the buffer holder 1212 may be actually configured according to the conveying device of the conveyor mechanism 12 of the actual mineral product sorter. The buffer strip 1211 is fixedly mounted on the buffer bracket 1212 through the locking device 1213 by a plurality of locking methods such as bolting, snapping, etc. It should be understood that the number of the buffering strips 1211, the installation manner of the buffering strips 1211 on the buffering bracket 1212 and the locking manner should not be construed as limiting the specific protection scope of the present application.

Further, in an embodiment provided in the present application, the bumper strip 1211 specifically includes: wear plate 12111; a carrier plate 12112; a rubber layer 12113 connecting the wear plate 12111 to the carrier plate 12112.

Specifically, as shown in fig. 4, in a preferred embodiment provided by the present application, the damping strip 1211 in the damping device 121 is mainly composed of two materials, namely a wear plate 12111 and a carrier plate 12112, which are connected by a rubber layer 12113. Compared to the conventional metal pallet and the polymer wear-resistant pallet, the buffer strip 1211 is not a separate metal pallet or a non-metal pallet, but is formed by combining the metal pallet and the polymer wear-resistant pallet. The wear plate 12111 and the bearing plate 12112 may be made of metal for the wear plate 12111 and non-metal for the bearing plate 12112, or made of non-metal for the wear plate 12111 and metal for the bearing plate 12112. It will be appreciated that the particular material arrangement of the wear plate 12111 and the carrier plate 12112 in a preferred bumper strip 1211 as provided herein is clearly not intended to limit the scope of the present invention.

It should be noted that the material of the wear plate 12111 of the buffer 121 is selected to satisfy a certain coefficient of friction, which is defined as the wear plate 12111 of the buffer strip 1211. In a preferred embodiment provided herein, wear plate 12111 acts as the upper surface of buffer strip 1211, i.e., wear plate 12111 of buffer strip 1211 contacts the conveyor belt of transport mechanism 12 when ore in feed mechanism 11 contacts the conveyor belt. Most of the materials of the inner surface layer of the prior conveying belt are canvas braided layers and PVG rubber. When the metal pallet is used as the wear plate 12111, the surface of the woven canvas layer between the metal pallet and the conveyor belt has a non-lubricated coefficient of friction of about 0.1, but a non-lubricated coefficient of friction of 0.4 to 0.7 with the surface of the rubber in the conveyor belt. The non-metallic carrier has a non-lubricated coefficient of friction of 0.1-0.15 with the rubber surface, so that the wear plate 12111 is used as the contact portion of the buffer strip 1211 with the conveyor belt, and the non-metallic carrier is selected as the wear plate 12111. The PVG rubber is a flame-retardant conveying belt, and has the advantages of no delaminating, impact resistance, small elongation and tearing resistance. The flame-retardant belt can be divided into PVC type (plastic surface) and PVG type (flame-retardant conveyor belt and coal mine conveyor belt) whole-core flame-retardant belts according to different structures.

It should also be noted that another part of the cushioning strip 1211 in the cushioning device 121, namely the carrier plate 12112. The carrier plate 12112 should be made of a material with a certain load-bearing capacity as a part of the bumper strip 1211. In the conventional buffer device 121, the buffer strip 1211 performs the buffering and supporting functions of the buffer strip 1211 only by using a single metal pallet, and the buffering and supporting functions cannot be fully realized. When a metal pallet is used as the buffer strip 1211 in the prior art, the metal pallet generally uses an aluminum profile as the buffer device 121 for buffering and bearing, and when the aluminum profile exerts the bearing capacity, the aluminum profile generally needs to be used in combination with a tray and some brackets, and the aluminum profile cannot be used as the bearing plate 12112 alone. In a preferred embodiment provided herein, the material of the carrier plate 12112 is selected to be a metal with a certain strength, and the structure of the carrier plate 12112 is optimized to perform the independent bearing function of the carrier plate 12112.

Further, in one embodiment provided herein, the material of the carrier plate 12112 is a carbon steel material.

Specifically, the bearing plate 12112 in the bumper strip 1211 can exert its bearing capacity, and can be made of other materials having the same bearing capacity as the carbon steel material, so as to exert its bearing capacity. For example, an alloy material of a metal type may be used as the material of the carrier plate 12112. In a preferred embodiment provided herein, a carbon steel material is preferred as the material for the carrier plate 12112.

It should be noted that the carrier plate 12112, when carbon steel is selected as its load bearing material, can independently carry the load transmitted from the belt and ore. Compared with a metal supporting plate or a metal supporting plate used in combination with other structures for increasing the bearing capacity, the bearing plate 12112 has a relatively strong bearing capacity of carbon steel, and the bearing plate 12112 is used as a part of the buffer strip 1211 and does not need to occupy more space to exert the bearing function.

Further, in an embodiment provided herein, the carrier plate 12112 includes: a substrate 121121; a transverse rib 121122 provided on the substrate 121121; longitudinal ribs 121123 provided on the substrate 121121.

Specifically, the structure of the bearing plate 12112 in the buffer device 121 is further optimized on the premise that the bearing plate 12112 is made of carbon steel material to exert the bearing capacity. As shown in fig. 5, the carrier plate 12112 includes: a substrate 121121; a transverse rib 121122 provided on the substrate 121121; longitudinal ribs 121123 provided on the substrate 121121.

It should be noted that by adding the transverse ribs 121122 and the longitudinal ribs 121123 to the carrier plates 12112 in the bumper strip 1211, the cushioning capacity of the bumper strip 1211 can be increased to some extent, and the surface of the wear plate 12111 of the bumper strip 1211 is less likely to deform under the action of the ribs of the bumper strip 1211. It will be appreciated that the wear plate 12111 and carrier plate 12112 are connected by a rubber connection. The ribs in the carriers 12112 are filled with rubber and above the rubber filled carriers 12112 are wear plates 12111, which are polyurethane plates. The provision of the ribs prevents collapse of the rubber and thus deformation of the wear plate 12111.

It is understood that the transverse ribs 121122 and the longitudinal ribs 121123 provided on the substrate 121121 of the carrier plate 12112 are provided to increase the load-bearing capacity of the carrier plate 12112. The specific arrangement position of the reinforcing ribs and the thickness of the reinforcing ribs obviously do not constitute a specific limitation to the protection scope of the application.

Further, in a preferred embodiment provided by the present application, a T-shaped channel may be further disposed on the substrate 121121 in the carrier plate 12112; for improving the load-bearing capacity of the carrier plate 12112.

Specifically, the substrate 121121 of the carrier plate 12112 may be provided with other structures besides the transverse ribs 121122 and the longitudinal ribs 121123, which can improve the carrying capacity of the carrier plate 12112. In the cross-sectional structure of the supporting plate 12112 of the damping device 121 shown in fig. 5, not only the transverse ribs 121122 and the longitudinal ribs 121123, but also a T-shaped channel is provided to improve the bearing capacity of the supporting plate 12112.

It should be noted that other ribs may be disposed on the substrate 121121 of the carrier plate 12112 to improve the carrying capacity of the carrier plate 12112. It will be appreciated that the added structure of the carrier plate 12112 that enhances the ability of the carrier plate 12112 does not constitute a limitation to the specific scope of the present application.

Further, in an embodiment provided in the present application, the transverse stiffener 121122 disposed on the substrate 121121 specifically includes: the transverse ribs 121122 on the substrate 121121 are spaced apart by a distance of 50mm to 200mm.

Specifically, the spacing distance between the lateral ribs 121122 provided on the substrate 121121 in the carrier plate 12112 is set to 50mm to 200mm. The arrangement of the transverse ribs 121122 and the longitudinal ribs 121123 in the carrying plate 12112 is to improve the carrying capacity of the carrying plate 12112, the transverse ribs 121122 are arranged between 50mm and 200mm, and it is also considered that when the buffering strip 1211 plays a role in the buffering device 121, that is, when ore falls into the conveyor belt of the conveying mechanism 12, the buffering strip 1211 is not stressed at all positions, but is stressed at the middle position in the buffering process more frequently, which results in that when the transverse ribs 121122 are arranged in the carrying plate 12112, the spacing distance between the transverse ribs 121122 near the middle position is small, the spacing distance between the transverse ribs 121122 near the two end positions is large, or they can be arranged at equal spacing distances. The transverse ribs 121122 are provided between 50mm and 200mm, and it is also considered that there are places where a small number of ribs can be provided, i.e., ribs are provided every 200mm, thereby reducing the cost. The minimum distance between the transverse reinforcing ribs 121122 is 50mm, so that the maximum bearing effect of the reinforcing ribs can be achieved when the distance between the reinforcing ribs is 50mm, and the cost can be reduced. If the distance between the lateral ribs 121122 and the bearing capacity of the carrier plate is set to be between 10mm and 50mm, the difference between the bearing capacity and the bearing capacity of 50mm is not large, and if the distance between the lateral ribs 121122 and the bearing capacity is small, the cost of the carrier plate 12112 will increase due to the excessive number of the lateral ribs 121122.

It will be appreciated that the spacing of the longitudinal ribs 121123 of the carrier plate 12112 is also considered to increase the load bearing capacity of the carrier plate 12112 while reducing the cost of manufacture thereof.

Further, in an embodiment provided herein, the wear plate 12111 is made of one of polyurethane and polyethylene.

Specifically, the wear plate 12111 of the bumper strip 1211 is made of one of polyurethane and polyethylene. Considering wear plate 12111 as the portion of bumper strip 1211 that contacts the conveyor belt, wear plate 12111 should be able to provide a material with a low coefficient of friction to function as wear plate 12111.

It should be noted that in the conventional buffer device 121 of the mineral product sorter 100, the buffer function and the load-bearing function are mainly performed by a single high-molecular wear-resistant pallet. The high-molecular wear-resistant supporting plate can be made of a polyethylene material or a polyurethane material. In a preferred embodiment of the present application, the wear plates 12111 of the bumper strips 1211 of the bumper assembly 121 are made of a polyurethane material to provide cushioning. This is in consideration of the fact that the ore and the washing water conveyed in the ore separator 100 contain acid or alkali components, and are corrosive; the mineral separator 100 contains an emitter for identifying X-rays, with radiation. Compared with polyethylene, polyurethane has the advantages of acid-base corrosion resistance and radiation resistance, and is more favorable for being combined with rubber for connecting the wear-resisting plate 12111 and the bearing plate 12112 in the buffer strip 1211.

Further, in an embodiment provided herein, the rubber layer 12113 connecting the wear plate 12111 and the bearing plate 12112 specifically includes:

the wear plate 12111 and carrier plate 12112 are joined by a vulcanized rubber using a heat vulcanization process to form the bumper strip 1211.

Specifically, the wear plate 12111 and the carrier plate 12112 are heat vulcanized with rubber to form the bumper strip 1211. Vulcanization is also known as crosslinking and curing. Adding cross-linking assistant, such as vulcanizing agent and promoter, into rubber, and converting linear macro molecule into three-dimensional network structure under certain temperature and pressure. Vulcanization is known because the cross-linking of natural rubber was first achieved with sulfur. It can be divided into cold vulcanization, room temperature vulcanization and hot vulcanization according to vulcanization conditions. The cold vulcanization can be used for the vulcanization of film products, and the products are dipped in a carbon disulfide solution containing 2 to 5 percent of sulfur chloride, and then are cleaned and dried. In the case of room temperature vulcanization, the vulcanization process is carried out at room temperature and normal pressure, such as the use of room temperature vulcanized rubber cement (rubber compound solution) for bicycle inner tube joints, repair and the like. Heat vulcanization is the primary method of vulcanization of rubber articles. According to the difference of vulcanization medium and vulcanization mode, the hot vulcanization can be divided into three methods of direct vulcanization, indirect vulcanization and mixed gas vulcanization. (1) And (3) direct vulcanization, namely directly putting the product into hot water or a steam medium for vulcanization. (2) The indirect vulcanization is carried out, and the product is vulcanized in hot air, and the method is generally used for certain products with strict appearance requirements, such as rubber shoes and the like. (3) And (3) mixed gas vulcanization, namely air vulcanization is adopted firstly, and then direct steam vulcanization is adopted. The method can overcome the defect that the appearance of the product is influenced by steam vulcanization, and can also overcome the defects that the vulcanization time is long and the product is easy to age due to slow heat transfer of hot air.

It should be noted that in a preferred embodiment provided herein, the wear plate 12111 is a polyurethane plate and the carrier plate 12112 is a carbon steel material. The carrier plate 12112 includes a substrate 121121, a transverse rib 121122 provided on the substrate 121121, and a longitudinal rib 121123 provided on the substrate 121121. When the bearing plate and the wear-resisting plate are vulcanized, the polyurethane plate and the carbon steel material can be placed into the mold through the clamping tooling mold, and rubber is uniformly vulcanized and filled in a semi-closed cavity consisting of the reinforcing ribs and erected between the bearing plate 12112 and the wear-resisting plate 12111.

It will be appreciated that the rubber curing fills the semi-enclosed cavity of the carrier plate 12112 comprised of the reinforcing ribs and also provides a connection to the wear plate 12111. The rubber is injected into the reinforcing ribs of the carrier plate 12112, which effectively prevents the rubber from collapsing and ensures the level of the upper surface of the polyurethane plate, i.e., the level of the surface of the bumper strip 1211 that contacts the belt. Meanwhile, the function of independent bearing reinforcement is also achieved.

It will also be appreciated that other reinforcing bars, such as T-channel steel, may be added to the carrier plate 12112. When rubber is filled into the ribs of the carrier plate 12112, it is also to increase the load-bearing capacity of the carrier plate 12112 and to extend the service life of the carrier plate 12112.

Further, in an embodiment provided herein, when the wear plate 12111 and the carrier plate 12112 are connected to form the bumper strip 1211 by vulcanized rubber through a thermal vulcanization process, the method further includes:

and a flame retardant is added into the rubber for flame retardance and explosion suppression.

Specifically, the flame retardant may be added during the production of the polyurethane board and the rubber, or may be added during the formation of the bumper strip 1211. It will be understood that the specific timing of the addition of the flame retardant described herein, clearly, should not be construed as limiting the scope of the present application. It will also be appreciated that the addition of fire retardant is to make the ore separator 100 less prone to fire or to self-extinguish after leaving a fire, to isolate the source of the explosion from explosive gases or dust and the like during the separation of the ore.

Further, in one embodiment provided herein, the vulcanized rubber layer 12113 connecting the wear plate 12111 to the carrier plate 12112 has a height of between 1mm and 10 mm.

Specifically, after the rubber layer 12113 connecting the wear plate 12111 and the carrier plate 12112 is subjected to a heat vulcanization treatment, the height of the vulcanized rubber layer 12113 between the carrier plate 12112 and the wear plate 12111 is 1mm to 10 mm.

It should be noted that the height values described herein are flexibly set according to the load that the buffer device 121 can bear. When the cushion 121 is subjected to a load of between 150 kg and 200 kg, the vulcanized rubber layer 12113 between the carrier plate 12112 and the wear plate 12111 may be set to a height of 5 mm; when the damper 121 is subjected to a load of more than 200 kg, the height of the vulcanized rubber layer 12113 between the carrier plate 12112 and the wear plate 12111 may be set to a value of more than 5mm and less than 10 mm. It is understood that the height of the vulcanized rubber layer 12113 between the carrier plate 12112 and the wear plate 12111 as described herein may be varied in many ways depending on the setting elements, and should not be construed as limiting the scope of the present invention.

Further, in one embodiment provided herein, the wear plate 12111 has a surface flatness value of between 0.01mm and 0.05 mm.

Specifically, the flatness refers to a deviation of a macro concavo-convex height of the substrate from an ideal plane. The tolerance zone is the area between two parallel planes at a distance of the tolerance value t. The flatness belongs to the shape error in the form and position errors. The shape error is the variation of the measured actual element to the ideal element, and the position of the ideal element should meet the minimum condition. Shape errors are classified into 6 types of straightness, flatness, roundness, cylindricity, line profile, and surface profile, of which the first 3 types are most common.

It should be noted that the surface of the wear plate 12111 in the buffer device 121, i.e. the surface of the buffer strip 1211 that is in contact with the conveyor belt in the transport mechanism 12. The planeness value is set between 0.01mm and 0.05mm, so that the contact and transmission efficiency of the working face and the conveying belt can be improved to the maximum extent.

It will be appreciated that the flatness value of the wear plate 12111 is between 0.01mm and 0.05mm, as confirmed after both wear plate 12111 and carrier plate 12112 have been vulcanized through rubber to form bumper strip 1211. The surface of wear plate 12111 may be finished by clamping bumper strip 1211 to the planer to ensure flatness of wear plate 12111. The edges of the wear plates 12111 in the bumper strip 1211 may also be radiused to improve the contact and drive efficiency of the work surface, it being understood that the finishing, radiused design of the bumper strip 1211 is provided to provide the bumper strip 1211 with sufficient cushioning in the mineral separator 100. It is understood that the processing, design and other methods of the buffer strip 1211 capable of improving the buffering of the buffer strip 1211 do not limit the scope of the present invention.

And a detection mechanism 13 for detecting the ore at a predetermined position. In one implementable embodiment provided herein, the mineral product enriched in the element to be extracted is separated from the slag depleted 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 can be loaded with different recognition 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.

In an implementation manner provided by the present application, the sorting mechanism 14 includes an air spraying device, a liquid spraying device or a manipulator.

The ore is disengaged from the transport mechanism 12 after continued movement of the transport mechanism 12 past 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 is being removed from the conveyor 12, and hence the drop point of ore, may be varied by means of a jet device during removal of ore from the conveyor 12. It can be understood that the gas injection device only needs to be provided with compressed gas to realize the separation of ore meeting the conditions, 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 cleaning of the ore can be realized, 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 the subsequent treatment of the ore is facilitated.

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 ore transfer device for transferring the separated ore.

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.

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.

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 only needs to be provided with compressed gas to realize the separation of ore meeting the conditions, and the realization cost is low.

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 configured 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 thus, the length of the conveyance mechanism 12 in the conveyance direction can be made as small as possible, and the mineral sorting machine 100 can be easily miniaturized.

In a preferred embodiment provided by the present application, the buffer device 121 is applied to the transmission mechanism 12 of the mineral sorting machine, so that the conveying efficiency of the mineral sorting machine can be improved, and considering that the mineral sorting machine 100 is used for mining ores, a flame retardant polymer is added into polyurethane, and a metal bracket is made of a carbon steel material, so that the buffer device 121 meets the coal safety engineering requirements, and is suitable for the underground environment of a coal mine.
