[0001] The invention belongs to the technical field of antimony-arsenic separation, in particular to an antimony-arsenic deep separation device. Background Art

[0002] According to Chinese patent publication number CN220224279U, a device for deep separation of antimony and arsenic from alkali slag from pyrometallurgical antimony and arsenic is disclosed. The device comprises a catalyst dissolver and an oxidation reactor. A cover plate is provided on the right side of the oxidation reactor for providing oxygen required for the oxidation reaction. Leaching water of an appropriate proportion is added, steam is introduced into a heating coil for heating, stirring is started, the leaching temperature is heated to 50-60°C, leaching is carried out for about 2 hours, the leaching pump is started, the leaching bottom valve is opened, and the leaching slag liquid is pumped into a plate and frame filter press for filtration. Air is then blown into the filter press through the cooperation of the press and the liquid collecting tank, and finally separation is completed through heating and smelting.

[0003] Although the above technical solution can separate antimony and arsenic, the process of pyrometallurgical antimony smelting is very complicated. Due to the proportional addition of corresponding ingredients and heating treatment, there is often a large amount of smoke and dust, and the antimony alloy content volatilizes into the dust. The direct recovery rate of antimony is relatively low, and there is still room for improvement. In addition, the foaming slag produced by the arsenic alkaline slag is dry slag in a solid state, which requires manual slagging, a large amount of work, and high labor intensity. For this reason, the present invention provides an antimony-arsenic deep separation device to solve the above problems. Summary of the Invention

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an antimony-arsenic deep separation device described in the present invention comprises a base, a leaching separation kettle is fixedly connected to the top of the base, a placement plate is clamped on the outer edge of the base, the placement plate is located outside the leaching separation kettle, a conveying assembly is provided on the top of the placement plate, and the conveying assembly is used to transport the catalytic substance added to the material, a sleeve frame is sleeved on the outer side of the placement plate, a cover plate is sleeved on the top of the leaching separation kettle, a separation assembly is provided in the cover plate, and the separation assembly is used to improve the efficiency of antimony-arsenic separation, a central shaft is rotatably installed at the center of the cover plate, a motor is externally connected to the top of the central shaft, and the top of the central shaft is connected to the output end of the motor; when working, in the process of separating antimony by pyrometallurgy, it is necessary to stir the arsenic-alkali slag to facilitate the subsequent slagging operation of the arsenic-alkali slag, and the slagging is generally done manually, which is relatively inconvenient. By using the present invention The invention discloses a method for preparing the arsenic alkali slag by first adding the crushed arsenic alkali slag from the groove on the side of the cover plate, and then directly feeding it into the leaching separation kettle after crushing and metering. After adding leaching water of appropriate proportion, steam is introduced to heat the arsenic alkali slag, and then stirring is performed. At this time, the servo motor is started, and the servo motor drives the movement of the central axis, and the central axis rotates to drive the separation component to gradually work. Through the setting of the separation component, the arsenic alkali slag is gradually rotated and squeezed. After the arsenic alkali slag is squeezed and slides to various directions and evenly spread out, the slag is automatically removed, eliminating the tedious manual operation and improving the efficiency of separating antimony and arsenic. In this process, the smoke dust inside the leaching separation kettle is dispersed by the setting of the central axis and the separation component, so that the smoke dust rising from the bottom is indirectly transported upward, so that the volatility of the smoke dust is reduced when the smoke dust moves to the top, thereby reducing the antimony and gold content volatilized in the smoke dust, and ensuring the maximum preservation of the antimony content. Finally, the antimony and arsenic separation effect is optimized by improving the slag removal and changing the loss of antimony content.

[0006] Furthermore, the separation component includes a through cavity, the middle part of the through cavity is rotatably installed with the central axis, a turntable is fixedly connected to the outer side of the central axis, the central axis rotates and the turntable is linked to run, the turntable twists, and the twisting of the turntable gradually acts on the fan blades and the support legs, the turntable is located below the central axis, the outer edge of the turntable is fixedly connected to the support legs, and the top of the central axis is located in the through cavity and is fixedly connected to the fan blades.

[0007] Furthermore, the centers of the turntable and the fan blades are in the same straight line, and the bottom end of the through cavity is provided with evenly distributed notches; during operation, since the foam slag produced by the arsenic alkali slag is dry slag and in a solid state, manual slag removal is required, which is labor-intensive and time-consuming. When using the embodiment of the present invention, the central axis is energized and rotates counterclockwise, and the central axis rotates to link the turntable to run, and the turntable twists. The twisting of the turntable gradually acts on the fan blades and the support legs, and the fan blades accelerate the blowing of the internal gas and discharge it through the side of the through cavity. When the support legs rotate, they gradually drive the solid antimony-arsenic slag at the bottom of the leaching separation kettle. Under the action of the rotating centrifugal force, the support legs quickly distribute the arsenic-alkali slag to various directions. After the arsenic-alkali slag is spread out, it is separated up and down along the sieve holes below the leaching separation kettle. The separated solid matter containing antimony and arsenic finally enters the base groove, thereby improving the degree of automation of the separation, saving operation time, reducing labor intensity, and improving work efficiency.

[0008] Furthermore, a dust separation component is provided on the outside of the central axis, and the dust separation component includes a roller, the side of the roller is rotatably connected to a traction rope, the top of the traction rope is transmission-connected to a card plate, a connecting bar is fixedly connected to the side of the card plate close to the roller, the outside of the connecting bar is telescopically connected to a cylinder, a thin shaft is inserted into the top of the cylinder, a solid ring is fixedly connected to the middle of the leaching separation kettle, a middle baffle is fixedly connected to the inner wall of the solid ring, the bottom of the middle baffle is folded and connected to a folding plate, and the thin shaft is arranged to pass through the sleeve frame.

[0009] Furthermore, the folding plate is fixedly connected to the fixed ring, the folding plate is supported on the middle baffle, the middle baffle is in the shape of an arc, and the cylinder is located below the fixed ring.

[0010] Furthermore, a slot corresponding to the connecting rod is provided inside the cylinder, the connecting rod is connected to the thin shaft, and the cylinder is fixed to the inner wall of the leaching separation kettle; during operation, the amount of smoke and dust is often large after heating, which causes the antimony alloy content to volatilize into the smoke and dust, resulting in a relatively low direct antimony recovery rate. The rotation of the central axis gradually links the roller and moves accordingly. The rotation of the roller drags the traction rope, and the traction rope gradually deforms. The traction rope gradually tightens the card plate and drives it. The card plate is dragged and displaced, and the card plate moves toward the card plate. The card plate slides in the right direction, and the connecting strip is pushed by the card plate, and the connecting strip is gradually inserted into the inside of the cylinder. When the card plate slides, it will contact the folding plate, and the folding plate will be folded upward. The folding plate is supported on the middle baffle bar. Under the support of the middle baffle bar, the folding plate fans the internal smoke and disperses the smoke, so that the smoke is gradually transported upward indirectly. The interval treatment of the smoke by the folding plate causes less volatilization of the antimony content in the internal smoke, ensuring that the value of the antimony direct recovery rate is not greatly reduced, thereby achieving the purpose of improving the separation depth.

[0011] Furthermore, the leaching separation kettle includes a crushing assembly, which includes a filter cartridge. The inner wall of the filter cartridge is fixed with crushing pieces, which crush the antimony ore. The crushing pieces drive the support columns to move synchronously, and the long torsion plates at the bottom ends of the support columns are gradually swung. The long torsion plates wipe the bottom when they are swung. The bottom ends of the crushing pieces are fixed with support columns, and the bottom ends of the support columns are rotatably connected to the long torsion plates. The center of the filter cartridge is sleeved on the outside of the central axis.

[0012] Furthermore, the support column is provided to pass through the long twist plate, the long twist plate is sleeved on the outer side of the support column, and the filter cartridge is in a circular ring shape. During operation, before the antimony and arsenic are separated, the ore containing the original antimony content needs to be crushed to facilitate the dissociation of various minerals in the antimony ore into monomer particles by crushing or grinding. After the crushing process, there is a problem of excessive dust adhering to the inner wall, which is not conducive to subsequent cleaning. By using the embodiment of the present invention, when the central shaft is driven, the filter cartridge is linked to move, and the filter cartridge rotates to link the crushing plate to rotate. The crushing plate crushes the antimony ore, and the crushing plate drives the support column to move synchronously. The long twist plate at the bottom end of the support column is gradually swung, and the long twist plate wipes the bottom when swinging. The wiping of the bottom of the filter cartridge by the long twist plate facilitates subsequent cleaning, achieving the effect of crushing while ensuring internal cleaning. At the same time, when the long twist plate rotates, it contacts the bottom of the support leg. The friction between the long twist plate and the support leg generates vibration. Under the action of the vibration force, the separation of solid particles containing antimony and arsenic and the cleaning efficiency are accelerated.

[0013] Furthermore, the conveying assembly includes an inclined plate, which contacts the inner wall of the card plate. The upper part of the inclined plate is displaced toward the leaching separation kettle under the relative action of force. The top of the inclined plate is movably fixedly connected to a rotating drum, the center of the rotating drum is fixedly connected to a pressure sensor, the bottom end of the rotating drum is fixedly connected to a filter tube, the bottom end of the filter tube is slidably connected to a catalytic conveying plate, the side of the inclined plate close to the leaching separation kettle is fixedly connected to a telescopic spring, the inside of the sleeve frame is slidably connected to a bow plate, the bow plate is arranged to penetrate the sleeve frame, and the telescopic spring is elastically connected to the leaching separation kettle.

[0014] Furthermore, the inclined plate is arranged to pass through the sleeve frame, and the top of the inclined plate is fixedly connected to the catalytic conveying plate; during operation, in the process of separating antimony and arsenic, a solid catalyst manganese sulfate needs to be added for catalytic treatment. When directly added, a chemical reaction is generated due to the combined heating treatment, which easily generates a large amount of smoke and dust in an instant, and there will be a volatilization effect, which affects the subsequent separation. Using the embodiment of the present invention, after the solid catalyst manganese sulfate is added to the inside of the drum, the central shaft is energized and moves, and the rotation of the central shaft drives the connecting rod to move. The connecting rod displacement squeezes the thin shaft, and the thin shaft drags the inclined plate outward to move synchronously. The inclined plate contacts the inner wall of the card plate, and the upper part of the inclined plate moves toward the direction close to the leaching separation kettle under the relative action of the force. The inclined plate squeezes the telescopic spring to move, and the bow plate blocks the driving direction of the inclined plate. The telescopic spring deforms and gradually compresses slowly. The catalytic conveying plate slowly extends into the inside of the leaching separation kettle under the buffering of the telescopic spring, so that the solid catalyst manganese sulfate inside the catalytic conveying plate has the function of slow addition, preventing the instantaneous generation of a large amount of smoke and dust from affecting the separation effect. At the same time, after the central shaft rotates a certain number of times, it has the function of automatic recombination.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The antimony-arsenic deep separation device described in the present invention is gradually inserted into the interior of the cylinder through the displacement of the connecting bar. When the card plate slides, it will contact the folding plate, and the folding plate will be folded upward. The folding plate is supported on the middle baffle bar. Under the support of the middle baffle bar, the folding plate fans the internal smoke and disperses the smoke, so that the smoke is gradually transported upward indirectly. The interval treatment of the smoke by the folding plate causes the antimony content contained in the internal smoke to volatilize less, ensuring that the value of the antimony direct recovery rate is not greatly reduced, thereby achieving the purpose of improving the separation depth.

[0017] 2. The antimony-arsenic deep separation device described in the present invention drives the support column to move synchronously through the crushing piece, and the long torsion plate at the bottom end of the support column is gradually swung, and the long torsion plate wipes the bottom when swinging. The wiping of the bottom of the filter cartridge by the long torsion plate facilitates subsequent cleaning, achieving the effect of crushing while ensuring internal cleaning; at the same time, the long torsion plate will contact the bottom of the support leg when rotating, and the long torsion plate and the support leg will rub to form vibration. Under the action of the vibration force, the separation of solid particles with antimony and arsenic content and the cleaning efficiency are accelerated. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Combine Figure 1 and Figure 2As shown, an antimony-arsenic deep separation device described in an embodiment of the present invention includes: an antimony-arsenic deep separation device, including a base 1, a leaching separation kettle 2 is fixedly connected to the top of the base 1, a placement plate 3 is clamped on the outer edge of the base 1, the placement plate 3 is located outside the leaching separation kettle 2, a conveying assembly is provided on the top of the placement plate 3, the conveying assembly is used to transport the catalytic substance added to the material, a sleeve frame 4 is sleeved on the outer side above the placement plate 3, a cover plate 5 is sleeved on the top of the leaching separation kettle 2, a separation assembly is provided in the cover plate 5, the separation assembly is used to improve the efficiency of antimony-arsenic separation, a central shaft 52 is rotatably installed at the center of the cover plate 5, a motor is externally connected to the top of the central shaft 52, and the top of the central shaft 52 is connected to the output end of the motor.

[0033] like Figure 1-Figure 2 As shown, during operation, in the process of separation by pyrometallurgical antimony smelting, the arsenic alkali slag needs to be stirred to facilitate the subsequent slag removal operation of the arsenic alkali slag. However, the slag removal is generally performed manually, which is relatively inconvenient. By using the present invention, the crushed arsenic alkali slag is first added from the groove on the side of the cover plate 5, and directly enters the leaching separation kettle 2 after crushing and metering. After adding leaching water and corresponding catalysts in appropriate proportions, steam is introduced to heat the arsenic alkali slag, and then a stirring and mixing operation is performed. At this time, the servo motor is started, and the servo motor drives the central shaft 52 to move. The central shaft 52 rotates to drive the separation component to gradually work. By setting up the separation component, the arsenic alkali slag is gradually rotated and squeezed. After the arsenic alkali slag is squeezed and slides to various directions and evenly spread out, the slag is automatically skimmed off, eliminating the tedious manual operation and improving the efficiency of separating antimony and arsenic. In this process, the smoke inside the leaching separation kettle 2 is dispersed by the setting up of the central axis 52 and the separation component, so that the smoke rising from the bottom is indirectly transported upward, and the volatility of the smoke is reduced when the smoke moves to the top, thereby reducing the antimony and gold content volatilized in the smoke, ensuring the maximum preservation of the antimony content, and finally optimizing the antimony and arsenic separation effect by improving the skimming and changing the loss of antimony content.

[0034] The separation component includes a through cavity 51, the bottom end of the through cavity 51 is provided with evenly distributed slots, the middle part of the through cavity 51 is rotatably installed with the central axis 52, a turntable 53 is fixedly connected to the outside of the central axis 52, the center of the turntable 53 and the fan blades 55 are on the same straight line, the turntable 53 is located below the central axis 52, and the outer edge of the turntable 53 is fixed with a support leg 54, and the top of the central axis 52 is located in the through cavity 51 and is fixed with the fan blades 55.

[0035] like Figure 1 、 Figure 2 、 Figure 5-Figure 7As shown, during operation, since the foamed slag produced by the arsenic-alkali slag is dry slag and is in a solid state, manual slag removal is required, which has a large workload and high labor intensity, and is time-consuming and labor-intensive. Using the embodiment of the present invention, the central shaft 52 is energized and rotates counterclockwise. The central shaft 52 rotates and the turntable 53 is linked to run, and the turntable 53 is twisted. The twisting of the turntable 53 gradually acts on the fan blades 55 and the support legs 54. The fan blades 55 accelerate the blowing of the internal gas and discharge it through the side of the cavity 51. When the support legs 54 rotate, they gradually drive the solid antimony-arsenic slag at the bottom of the leaching and separation kettle 2. Under the action of the rotating centrifugal force, the support legs 54 quickly distribute the arsenic-alkali slag to various directions. After the arsenic-alkali slag is spread out, it is separated up and down along the sieve holes opened at the bottom of the leaching and separation kettle 2. The separated solid matter containing antimony and arsenic finally enters the groove of the base 1, thereby improving the degree of automation of the separation, saving operation time, reducing labor intensity, and improving work efficiency.

[0036] A dust separation component is provided on the outside of the central axis 52, and the dust separation component includes a roller 521, a traction rope 522 is connected to the side of the roller 521, and a clamping plate 523 is connected to the top of the traction rope 522. A connecting rod 524 is fixed to the side of the clamping plate 523 near the roller 521. The connecting rod 524 is connected to the thin shaft 526. A notch corresponding to the connecting rod 524 is opened inside the cylinder 525. The outer side of the connecting rod 524 is telescopically connected to the cylinder 525. The cylinder 525 is fixedly connected to the inner wall of the leaching and separation kettle 2. The cylinder 525 is located below the fixed ring 527. A thin shaft 526 is inserted into the top of the cylinder 525. A fixed ring 527 is fixedly connected to the middle of the leaching and separation kettle 2. A middle baffle 529 is fixedly connected to the inner wall of the fixed ring 527. The middle baffle 529 is in the shape of an arc. The bottom of the middle baffle 529 is folded and connected to a folding plate 528. The folding plate 528 is fixedly connected to the fixed ring 527. The thin shaft 526 is set through the sleeve frame 4.

[0037] As shown in the figure, during operation, the amount of smoke and dust is often large after heating, which causes the antimony alloy content to volatilize into the smoke and dust, resulting in a relatively low antimony direct recovery rate. The central axis 52 rotates and gradually links the roller 521 to move accordingly. The roller 521 rotates to drag the traction rope 522, and the traction rope 522 gradually deforms. The traction rope 522 gradually tightens the card plate 523 and drives it. The card plate 523 is dragged and displaced. The card plate 523 moves and slides in the direction close to the sleeve frame 4. The card plate 523 pushes the connecting rod 524, and the connecting rod 524 moves It is gradually inserted into the interior of the cylinder 525. When the card plate 523 slides, it will contact the folding plate 528, and the folding plate 528 will be folded upward. The folding plate 528 is supported on the middle baffle 529. Under the support of the middle baffle 529, the folding plate 528 fans the internal smoke and disperses the smoke, so that the smoke is gradually transported upward indirectly. The interval treatment of the smoke by the folding plate 528 causes the antimony content in the internal smoke to volatilize less, ensuring that the value of the antimony direct recovery rate is not greatly reduced, thereby achieving the purpose of increasing the separation depth.

[0038] The leaching separation kettle 2 includes a crushing assembly, which includes a filter cartridge 41. The filter cartridge 41 is in a circular shape. Crushing pieces 42 are fixed to the inner wall of the filter cartridge 41. The bottom ends of the crushing pieces 42 are fixed to support columns 43. The support columns 43 are arranged to pass through the long torsion plate 44. The bottom ends of the support columns 43 are rotatably connected to the long torsion plate 44. The long torsion plate 44 is sleeved on the outside of the support columns 43, and the center of the filter cartridge 41 is sleeved on the outside of the central axis 52.

[0039] like Figure 5-Figure 6 As shown, during operation, before the antimony and arsenic are separated, the ore containing the original antimony content needs to be crushed to facilitate the dissociation of various minerals in the antimony ore into monomer particles through crushing or grinding. After the crushing process, there is a problem of excessive dust adhering to the inner wall, which is not conducive to subsequent cleaning. By using the embodiment of the present invention, when the central shaft 52 is driven, it is linked to the filter cartridge 41 and moves. The filter cartridge 41 rotates and the crushing pieces 42 are linked to rotate. The crushing pieces 42 crush the antimony ore. The crushing pieces 42 drive the support column 43 to move synchronously. The long torsion plate 44 at the bottom end of the support column 43 is gradually swung. The long torsion plate 44 wipes the bottom when swinging. The wiping of the bottom of the filter cartridge 41 by the long torsion plate 44 facilitates subsequent cleaning, achieving the effect of crushing while ensuring internal cleaning. At the same time, when the long torsion plate 44 rotates, it contacts the bottom of the support leg 54. The friction between the long torsion plate 44 and the support leg 54 generates vibration. Under the action of the vibration force, the separation of solid particles containing antimony and arsenic and the cleaning efficiency are accelerated.

[0040] The conveying assembly includes an inclined plate 31, the top of which is fixedly connected to a catalytic conveying plate 35, and the inclined plate 31 is arranged to pass through the sleeve frame 4. A rotating drum 32 is movably fixed to the top of the inclined plate 31, and a pressure sensor 33 is fixedly connected to the center of the rotating drum 32. A filter tube 34 is fixedly connected to the bottom end of the rotating drum 32, and the bottom end of the filter tube 34 is slidably connected to the catalytic conveying plate 35. A telescopic spring 37 is fixedly connected to the side of the inclined plate 31 close to the leaching and separation kettle 2, and a bow plate 36 is slidably connected to the inside of the sleeve frame 4. The bow plate 36 is arranged to pass through the sleeve frame 4, and the telescopic spring 37 is elastically connected to the leaching and separation kettle 2.

[0041] like Figure 3-Figure 4 As shown, during operation, in the process of separating antimony and arsenic, a solid catalyst manganese sulfate needs to be added for catalytic treatment. When directly added, a chemical reaction occurs due to the combined heating treatment, which easily generates a large amount of smoke and dust in an instant, and there will be a volatilization effect, which affects the subsequent separation. Using the embodiment of the present invention, after the solid catalyst manganese sulfate is added to the inside of the drum 32, the middle shaft 52 is energized and moves, and the rotation of the middle shaft 52 drives the connecting rod 524 to move. The displacement of the connecting rod 524 squeezes the thin shaft 526, and the thin shaft 526 drags the inclined plate 31 outward to move synchronously, and the inclined plate 31 and the inner part of the sleeve frame 4 are connected. The inclined plate 31 contacts the wall, and the upper part of the inclined plate 31 is displaced toward the leaching and separation kettle 2 under the relative action of the force. The inclined plate 31 squeezes the telescopic spring 37 to move, and the bow plate 36 blocks the driving direction of the inclined plate 31. The telescopic spring 37 is deformed and gradually compressed. The catalytic conveying plate 35 is slowly extended into the leaching and separation kettle 2 under the buffering of the telescopic spring 37, so that the solid catalyst manganese sulfate in the catalytic conveying plate 35 has the function of slow addition, preventing the instantaneous generation of a large amount of smoke and dust that affects the separation effect. At the same time, after the central axis 52 rotates a certain number of times, it has the function of automatic recombination.

[0042] Working principle: First, add the crushed arsenic alkali slag from the side groove of the cover plate 5, and directly enter the leaching separation kettle 2 after crushing and metering. After adding leaching water and corresponding catalysts in appropriate proportions, introduce steam to heat the arsenic alkali slag, and then stir and mix. Finally, sieve and complete the separation at the bottom groove of the base 1. During the stirring process, the central axis 52 rotates counterclockwise after being powered on. The central axis 52 rotates and the turntable 53 runs in conjunction with the rotation of the turntable 53. The rotation of the turntable 53 gradually acts on the fan blades 55 and the support legs 54. The fan blades 55 accelerate the blowing of the internal gas and discharge it through the side of the cavity 51. When the support legs 54 rotate, they gradually drive the solid antimony arsenic slag at the bottom of the leaching separation kettle 2. Under the action of the rotating centrifugal force, the support legs 54 The arsenic alkali slag is quickly distributed to all directions, completing the effect of rapid distribution and improving the degree of automated operation; at the same time, the rotation of the central axis 52 gradually links the roller 521 and moves accordingly, the rotation of the roller 521 drags the traction rope 522, the traction rope 522 gradually deforms, and the traction rope 522 gradually tightens the card plate 523 to drive, the card plate 523 moves to push the connecting bar 524, and through the cooperation of the card plate 523, the middle baffle 529 and the folding plate 528, the folding plate 528 is prompted to fan and disperse the internal smoke, so that the smoke is gradually indirectly transported upward, and the interval treatment of the smoke by the folding plate 528 ensures that the antimony content contained in the internal smoke is less volatilized, and the value of the antimony direct recovery rate is ensured not to be greatly reduced.

[0043] When the original antimony-arsenic alloy material needs to be crushed before separation, the central shaft 52 is driven to move the filter cartridge 41, and the filter cartridge 41 rotates to rotate the crushing piece 42, and the crushing piece 42 crushes the antimony ore. The crushing piece 42 cooperates with the support column 43 to make the long torsion plate 44 wipe the bottom synchronously, ensuring the cleanliness of the bottom while ensuring crushing, which is convenient for subsequent cleaning.
