Description

Technical Field

[0001] The present invention relates to the technical field of heavy separation and impurity removal of lepidolite, and particularly to a device for impurity removal in the heavy separation process of lepidolite. Background Art

[0002] Lepidolite is an important lithium source ore, which is widely used in industrial fields such as batteries, ceramics, and glass. However, during the beneficiation process of lepidolite, a large number of impurities are often co-produced, especially mineral impurities such as quartz, feldspar, and biotite. These impurities not only affect the quality of lepidolite products but also reduce the extraction efficiency of lithium. Therefore, efficiently performing heavy separation on lepidolite to remove impurities and improve the purity and recovery rate of lepidolite is an important research direction in current mining production.

[0003] When traditional beneficiation methods use gravity separation, to a certain extent, lepidolite can be separated from impurities. During the heavy separation process, the density differences of various minerals in the ore sand are utilized, and at the same time, the scouring of water flow is coordinated to provide a force perpendicular to the direction of gravity, quickly separating the ore sand with different mass densities in equally spaced grooves. However, during use, the force of lateral water scouring is constant and continuously attenuates during the process of passing through the grooves, causing the water body to flow out downward along with the inclination of the shaking table, and the efficiency of collecting the ore sand along with the flow of the water body is low. Some ore sand will adhere in the grooves, and a large amount of ore sand will remain on the inner wall of the grooves on the surface of the shaking table, affecting the overall accuracy of ore sand heavy separation screening.

[0004] When screening multiple types of ore sand for heavy separation, due to the different diameters of different types of ore sand, different groove widths are required. After updating the ore sand composition for heavy separation processing, it is necessary to clean and replace the bed surface of the shaking table, select an appropriate groove width, which increases the labor intensity. Therefore, a device for impurity removal in the heavy separation process of lepidolite is introduced. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for impurity removal in the heavy separation process of lepidolite to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solutions:

[0007] A device for impurity removal in the heavy separation process of lepidolite includes a water supply device, an ore supply device, and a support. A power device is arranged at the top of the support, the power device is connected to a shaking table, a feeding trough and a flushing trough are arranged adjacent to one side of the shaking table, the feeding trough conveys ore sand through the ore supply device, the flushing trough provides water through the water supply device, and the shaking table shakes through the power device;

[0008] The shaking table includes a table surface, on the surface of which a clamping groove is formed. A strip is clamped on the inner wall of the clamping groove. One end of the strip is connected to a supporting plate, and the bottom of the supporting plate is connected to the table surface through an installed adjusting device.

[0009] The adjusting device includes a longitudinal slide rail connected to one side of the table surface. A slider is clamped on the longitudinal slide rail through an installed longitudinal motor. The longitudinal motor is vertically arranged on the top of the slider. The slider is driven to move on the longitudinal slide rail by a roller arranged on the output shaft of the longitudinal motor. A transverse motor is horizontally arranged at the bottom of the slider. The output shaft of the transverse motor is connected to a transverse slide rail through a roller, and the transverse slide rail is installed at the bottom of the supporting plate.

[0010] Strip-shaped grooves are vertically formed on the surface of the table surface. A plurality of strip-shaped grooves are linearly and equidistantly distributed on the upper surface of the table surface. The plurality of strip-shaped grooves are used for screening ore sand. The clamping groove is horizontally formed on the inner wall of the strip-shaped groove. A detachable structure is formed among the table surface, the clamping groove, the strip and the supporting plate. On the table surface, the strip is pulled out along the inner wall of the clamping groove to disengage the clamping connection between the supporting plate and the table surface, and the table surface is disassembled. By using the space vacated by the clamping groove, the inner width of the inner wall of the strip-shaped groove on the surface of the table surface is increased, and the ore sand adhered to the surface of the table surface is cleaned by the water flow in the water supply device flushing the strip-shaped groove.

[0011] One end of the strip is connected to the supporting plate through an extrusion structure. The extrusion structure is composed of a clamping hole, a convex block and a spring. A clamping hole is formed on one side of the supporting plate close to the strip. One end of the strip is clamped with the inner wall of the clamping hole through a convex block arranged thereon. A spring is arranged parallel to the strip on the inner wall of the clamping hole. One end of the spring abuts against the convex block, and the other end of the spring abuts against the inner wall of the clamping hole. A pressure sensor is arranged in the spring. After the ore sand is beneficiated and impurity-removed by the shaking table, a small amount of ore sand remains adhered to the inner walls of the clamping groove and the strip-shaped groove on the upper surface of the table surface. The transverse motor is controlled to drive the strip and the supporting plate to reciprocate along the transverse slide rail to scrape the ore sand stuck between one side of the strip and the inner wall of the strip-shaped groove. Then, water is supplied through a flushing groove for flushing. The longitudinal motor is controlled to drive the strip and the supporting plate to pull out from the inner wall of the clamping groove. The longitudinal motor drives the strip to move along the direction of the longitudinal slide rail to quickly disassemble and wash the table surface and the supporting plate. Then, the transverse motor is controlled to adjust one end of the strip to fit with the other side of the inner wall of the strip-shaped groove. The longitudinal motor is controlled to make the strip slide along the direction of the strip-shaped groove. One end of the strip scrapes and cleans the inner wall of the strip-shaped groove. Through the pressure sensor arranged at one end of the strip, the flatness of the inner wall of the strip-shaped groove is checked, and the stuck ore sand is scraped at the same time, so that the supporting plate and the strip form a row comb structure, and the residual ore sand is quickly swept by using the row comb structure to improve the self-cleaning ability.

[0012] The power device includes a driving motor. The bottom of the driving motor is fixedly connected to a bracket. The output shaft of the driving motor is fixedly connected with a pulley through a coupling. The pulley is connected to a reciprocating mechanism. The output shaft of the reciprocating mechanism is connected to the bed surface through a universal joint. The bottom of the bed surface is movably connected to the bracket. By controlling the rotation of the driving motor in the power device, the driving motor drives the reciprocating mechanism by driving the pulley to rotate. The output shaft of the reciprocating mechanism drives the bed surface to perform linear shaking to screen the ore sand on the surface of the bed surface.

[0013] The bottom of the shaking table is connected to the bracket through an angle deflection device. The angle deflection device includes a hydraulic cylinder and a hinge. The hydraulic cylinder and the hinge are located at the bottom of the bed surface. The hydraulic cylinder and the hinge are symmetrically arranged at both ends of the card slot. The bottom of the hydraulic cylinder is movably connected to the bracket. The top horizontal rotating shaft of the hydraulic cylinder is connected to the bottom of the bed surface. The hinge is connected to the bottom of the bed surface through the bracket. By adjusting the length of the hydraulic cylinder, the bed surface is driven to deflect around the hinge to control the inclination angle of the bed surface.

[0014] A device for impurity removal in the heavy separation process of lepidolite mica also includes an aggregate device. The aggregate device is provided at the bottom of the shaking table and is used for collecting ore sand.

[0015] A visual observation device is provided on the top of the shaking table. The visual observation device is used to observe the distribution of ore sand on the bed surface. The visual observation device and the adjustment device constitute an ore sand control system.

[0016] In one embodiment, after the ore sand is injected onto the upper surface of the bed surface through the ore feeding device, the relative position of the tray and the bed surface is adjusted according to the particle size of the ore sand in the ore. When the particle size in the ore is relatively large, the transverse motor is started to drive the roller connected to the transverse motor to rotate, driving the transverse slide rail to move horizontally, synchronously adjusting the horizontal movement of the tray, moving the strip on the tray towards the inner wall of the card slot, so that the strip fits with the inner wall of the card slot, expanding the width of the strip-shaped groove on the bed surface, facilitating the screening and impurity removal of the ore sand with larger particle size, improving the impurity removal efficiency. When the particle size of the ore sand is small, on the contrary, the tray is adjusted to move in the reverse direction to narrow the width of the strip-shaped groove on the bed surface, quickly capturing small mineral particles, slowing down the flow rate of the water body, reducing water resource waste, and improving the accuracy.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] The present invention, through the provided power device and shaking table, can quickly adjust the width of the strip-shaped groove according to the particle size of the ore sand by means of an adjusting device, change the magnitude of the negative pressure generated by the flowing water on the ore sand inside the groove, increase the force on the ore sand, accelerate the flow of the ore sand on the table surface, improve the gravity separation efficiency, and facilitate the gravity separation and impurity removal of ore sands with various particle sizes and various components, reducing the labor consumption for replacing the widths of different strip-shaped grooves.

[0019] Meanwhile, by changing the water flow rate on the surface of the table, the waste of water is synchronously reduced, improving the environmental friendliness of the device;

[0020] In addition, by cooperating with the adjusting device to adjust the position of the strip, the inner wall of the strip-shaped groove can be quickly scraped, preventing the sticking and retention of ore sand from affecting the subsequent impurity removal efficiency of the ore sand.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] The technical solution provided by the present invention:

[0037] Please refer to Figure 1 , a device for impurity removal in the heavy separation process of lepidolite, including a water supply device, a mineral supply device and a bracket 1. A power device 2 is arranged at the top of the bracket 1. The power device 2 is connected to a shaking table 3. A feed chute 4 and a flushing water chute 5 are arranged adjacent to one side of the shaking table 3. The feed chute 4 conveys ore sand through the mineral supply device, the flushing water chute 5 provides water through the water supply device, and the shaking table 3 shakes through the power device 2.

[0038] Please refer to Figure 2 , the shaking table 3 includes a table surface 301. Card slots 302 are formed on the surface of the table surface 301. Long strips 303 are clamped on the inner walls of the card slots 302. One end of the long strip 303 is connected to a support plate 304. The bottom of the support plate 304 is connected to the table surface 301 through an installed adjusting device 305.

[0039] Please see Figure 3 and Figure 4 , the adjusting device 305 includes a longitudinal slide rail 3051. The longitudinal slide rail 3051 is connected to one side of the table surface 301. A slide block 3053 is clamped on the longitudinal slide rail 3051 through an installed longitudinal motor 3052. The longitudinal motor 3052 is vertically arranged on the top of the slide block 3053. The longitudinal motor 3052 drives the slide block 3053 to move on the longitudinal slide rail 3051 through a roller arranged on the output shaft. A transverse motor 3054 is horizontally arranged at the bottom of the slide block 3053. The output shaft of the transverse motor 3054 is connected to a transverse slide rail 3055 through a roller. The transverse slide rail 3055 is installed at the bottom of the support plate 304.

[0040] The water supply device consists of a conduit, a water supply tank, and a water pump. Through the conduits connected to both ends of the water pump, water is transported from the water supply tank to the flushing tank 5.

[0041] The ore supply device is provided with a flow valve and a conduit. The conduit is fixedly connected to the flow valve. The crushed ore sand is transported to the ore feeding tank 4 through a pipeline, and the flow rate of the ore sand is controlled by the flow valve.

[0042] In this embodiment, after the ore sand is injected onto the upper surface of the bed surface 301 by the ore supply device, the relative position of the support plate 304 and the bed surface 301 is adjusted according to the particle size of the ore sand in the ore sand. When the particle size of the ore sand is relatively large, the transverse motor 3054 is started to drive the roller connected to the transverse motor 3054 to rotate, driving the transverse slide rail 3055 to move horizontally, synchronously adjusting the horizontal movement of the support plate 304, moving the strip 303 on the support plate 304 towards the inner wall of the card slot 302, so that the strip 303 fits with the inner wall of the card slot 302, expanding the width of the strip-shaped groove on the surface of the bed surface 301, facilitating the screening and impurity removal of the ore sand with larger particle sizes, improving the impurity removal efficiency. When the particle size of the ore sand is relatively small, on the contrary, the movement of the support plate 304 is adjusted in the reverse direction to narrow the width of the strip-shaped groove on the surface of the bed surface 301, quickly capturing small mineral particles, slowing down the flow rate of the water body, reducing water resource waste, and improving the accuracy.

[0043] In addition, through the clamping connection between the strip 303 and the card slot 302, the connection between the support plate 304 and the bed surface 301 is stabilized. The support plate 304 and the bed surface 301 are connected through the adjusting device 305. The adjusting device 305 is fixed, so that the relative rest between the support plate 304 and the bed surface 301 is maintained, avoiding the wear of the support plate 304 and the bed surface 301 caused by the shaking of the power device 2 shaking the shaking table 3. At the same time, it is convenient for the user to disassemble and replace, reducing the influence of the ore sand wearing the shaking table 3 on the service life.

[0044] Please continue to refer to Figure 2 and Figure 3 , a strip-shaped groove is vertically opened on the surface of the bed surface 301. A number of strip-shaped grooves are linearly and equidistantly distributed on the upper surface of the bed surface 301. The number of strip-shaped grooves is used for screening ore sand. The card slot 302 is horizontally opened on the inner wall of the strip-shaped groove. A detachable structure is formed among the bed surface 301, the card slot 302, the strip 303, and the support plate 304.

[0045] In this embodiment, the strip 303 is pulled out along the inner wall of the card slot 302 to disengage the clamping connection between the support plate 304 and the bed surface 301, and the bed surface 301 is disassembled. By using the space vacated by the card slot 302, the inner wall width of the strip-shaped groove on the surface of the bed surface 301 is increased, and the water flow in the water supply device is used to wash the strip-shaped groove to clean the ore sand adhered to the surface of the bed surface 301.

[0046] Refer to Figure 6, one end of the long strip 303 is connected to the support plate 304 through the extrusion structure 306. The extrusion structure 306 is composed of a clamping hole 3061, a convex block 3062 and a spring 3063. A clamping hole 3061 is provided on the side of the support plate 304 close to the long strip 303. One end of the long strip 303 is clamped with the inner wall of the clamping hole 3061 through the provided convex block 3062. A spring 3063 is arranged on the inner wall of the clamping hole 3061 parallel to the long strip 303. One end of the spring 3063 abuts against the convex block 3062, and the other end of the spring 3063 abuts against the inner wall of the clamping hole 3061. A pressure sensor is arranged in the spring 3063.

[0047] Considering the problem that after the ore sand is reselected and purified by the shaking table 3, a small amount of ore sand remains sticky on the inner walls of the card slots 302 and the strip-shaped grooves on the upper surface of the bed surface 301.

[0048] In this embodiment, the transverse motor 3054 is controlled to drive the long strip 303 and the support plate 304 to reciprocate along the transverse slide rail 3055, so as to scrape the ore sand stuck on one side of the long strip 303 and the inner wall of the strip-shaped groove. Subsequently, water is supplied through the flushing tank 5 for flushing. The longitudinal motor 3052 is controlled to drive the long strip 303 and the support plate 304 to be withdrawn from the inner wall of the card slot 302. The longitudinal motor 3052 drives the long strip 303 to move along the direction of the longitudinal slide rail 3051 to quickly disassemble and wash the bed surface 301 and the support plate 304. Subsequently, the transverse motor 3054 is controlled to adjust one end of the long strip 303 to fit the other side of the inner wall of the strip-shaped groove, and the longitudinal motor 3052 is controlled to make the long strip 303 slide along the direction of the strip-shaped groove. One end of the long strip 303 scrapes and cleans the inner wall of the strip-shaped groove. Through the pressure sensor arranged at one end of the long strip 303, the flatness of the inner wall of the strip-shaped groove is checked, and at the same time, the stuck ore sand is scraped off, so that the support plate 304 and the long strip 303 form a row comb structure, and the residual ore sand is quickly swept by using the row comb structure to improve the self-cleaning ability.

[0049] Please refer to Figure 5 , the power device 2 includes a driving motor 201. The bottom of the driving motor 201 is fixedly connected to the bracket 1. The output shaft of the driving motor 201 is fixedly connected with a pulley 202 through a coupling. The pulley 202 is connected with the reciprocating mechanism 203. The output shaft of the reciprocating mechanism 203 is connected to the bed surface 301 through a universal joint. The bottom of the bed surface 301 is movably connected to the bracket 1.

[0050] In this embodiment, the ore feeding device pours the ore sand and water mixture into the ore feeding tank 4, laterally injects the ore sand onto the bed surface 301, and at the same time, the flushing water tank 5 arranged in parallel supplies water through the water supply device, injecting the water perpendicular to the shaking direction of the power device 2. Control the rotation of the drive motor 201 in the power device 2. The drive motor 201 drives the reciprocating mechanism 203 by driving the pulley 202 to rotate. The output shaft of the reciprocating mechanism 203 drives the bed surface 301 to perform linear shaking, screening the ore sand on the surface of the bed surface 301, so that the ore sand on the bed surface 301 is affected by the force of linear shaking, the force of the water flow perpendicular to the shaking direction, and its own gravity. On the bed surface 301, the ore sand is subjected to the thrust of the water flow in the horizontal direction. The water flow helps to wash the impurities in the ore sand and makes the particles spread more evenly on the surface. At the same time, it is affected by the vibration of the power device 2 on the bed surface 301. The vibration causes the ore sand to move longitudinally and laterally on the bed surface. Due to the vibration, the heavier mineral particles tend to settle downward, while the lighter particles move farther. The heavy selection and impurity removal are quickly carried out by using the density difference of the ore sand. The gravity makes the particles classified according to their density and size. The heavy minerals are concentrated at the lower part of the bed surface due to gravity settlement, while the light minerals tend to the surface. The heavy minerals are less affected by the water flow during the movement and are easy to gather on the bed surface to form a certain ore sand layer, while the light minerals are more easily washed away by the water flow. Through the combination of the above three forces, the minerals with different densities and particle sizes gradually form a layered separation.

[0051] The bottom of the shaking table 3 is connected to the support 1 through an angle deflection device. The angle deflection device includes a hydraulic cylinder and a hinge. The hydraulic cylinder and the hinge are located at the bottom of the bed surface 301, and the hydraulic cylinder and the hinge are symmetrically arranged at both ends of the clamping groove 302. The bottom of the hydraulic cylinder is movably connected to the support 1, the top horizontal shaft of the hydraulic cylinder is connected to the bottom of the bed surface 301, and the hinge is connected to the bottom of the bed surface 301 through the support 1. By adjusting the length of the hydraulic cylinder, the bed surface 301 is driven to deflect around the hinge, controlling the inclination angle of the surface of the bed surface 301. By changing the inclination angle of the bed surface 301, the water flow speed and the movement speed of the ore sand on the bed surface are controlled. At the same time, by adjusting the inclination angle, the recovery amount and grade of the final product are controlled;

[0052] When separating the light minerals, the bed surface 301 adopts an inclination angle of 0° - 5°, and the water flow speed is relatively fast, which can effectively discharge the lighter minerals;

[0053] When separating the heavy minerals, the bed surface 301 adopts an inclination angle of 5° - 10°. With the increase of the inclination angle, under the combined action of gravity, friction and fluid flow characteristics, the flow rate of the water flow slows down. After the water flow speed decreases, it helps the heavy minerals to precipitate on the bed surface;

[0054] At the same time, when cleaning the surface of the bed surface 301, it is cleaned by changing the inclination angle of the bed surface 301 in cooperation with the water body flushing.

[0055] In this embodiment, by deflecting the inclination angle of the shaking table 3 and cooperating with the long strip 303 to slide and scrape along the strip-shaped groove, the sticky and stuck ore sand is cleaned. The water flows rapidly along the inclined bed surface 301, and the bed surface 301 is quickly cleaned by gravity, improving the cleaning efficiency of the bed surface 301.

[0056] A device for removing impurities in the re-election process of lepidolite mica further includes an aggregate device. An aggregate device is provided at the bottom of the shaking table 3, and the aggregate device is used to collect the ore sand. The aggregate device is composed of a plurality of aggregate boxes, and the aggregate boxes are arranged directly below the shaking table 3 to collect the ore sand washed down.

[0057] A visual observation device is provided on the top of the shaking table 3. The visual observation device is composed of a camera, and the camera is arranged perpendicular to the surface of the shaking table 3. The visual observation device is used to observe the distribution of the ore sand on the bed surface 301, collect the flow information of the ore sand on the upper surface of the shaking table 3, and collect, analyze and judge the distribution of the ore sand.

[0058] The visual observation device and the adjustment device 305 constitute an ore sand control system. Among them, the visual observation device includes a camera, which collects the distribution of the ore sand on the bed surface 301 to facilitate determining the size of the ore sand particles. Subsequently, the visual observation device controls the adjustment device 305 to adjust the width of the strip-shaped groove to improve the working efficiency of ore sand screening.

[0059] Specifically, the visual observation device observes the distribution of the ore sand on the bed surface 301 through the camera;

[0060] When the particles are evenly distributed, it indicates that the particle size is small and the dispersion is good.

[0061] When the particles are piled up, it indicates that the particle size is large and there is a blockage. At this time, control the adjustment device 305 to adjust the width of the strip-shaped groove, press the long strip 303 against the inner wall of the card slot 302, and adjust the width of the strip-shaped groove to the maximum. If the blockage is relieved, it indicates that the requirements for re-election screening are met. If the blockage still exists, it indicates that there is sticky and stuck ore sand particles. Control the longitudinal motor 3052 in the adjustment device 305 to make the long strip 303 reciprocate and rub with the card slot 302 to clean the sticky ore sand particles, and at the same time push the ore sand in the strip-shaped groove to the top of the bed surface 301 to re-perform re-election and impurity removal to ensure the quality of the ore sand.
