Description

Technical Field

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

[0003] 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, comprising a catalyst dissolver and an oxidation reactor, wherein a cover plate for providing oxygen required for the oxidation reaction is provided on the right side of the oxidation reactor; by adding leaching water of appropriate proportion, heating the coil with steam for heating, starting stirring, heating the leaching temperature to 50-60°C, leaching for about 2 hours, starting the leaching pump, opening the leaching bottom valve, pumping the leaching slag liquid into a plate and frame filter press for filtration, and then blowing air in after the cooperation of the press and the liquid collecting tank, and finally completing the separation through heating and smelting.

[0004] In the above technical scheme, although the separation of antimony and arsenic can be completed, the process of pyrometallurgical antimony refining is also very complicated. Due to the proportional addition of corresponding ingredients and heating treatment, there is often a large amount of smoke and dust, the antimony alloy content volatilizes into the dust, and the direct recovery rate of antimony is relatively low. There is still room for improvement. The foam 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

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: the 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 component is arranged on the top of the placement plate, the conveying component is used to transmit the catalytic substance added to the material, a sleeve frame is sleeved on the outer side above the placement plate, a cover plate is sleeved on the top of the leaching separation kettle, a separation component is arranged in the cover plate, the separation component 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 separation by pyrometallurgical antimony smelting, it is necessary to stir the arsenic-alkali slag to facilitate the subsequent slag removal operation of the arsenic-alkali slag, and the slag removal is generally performed 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, directly feeding the crushed arsenic alkali slag into the leaching separation kettle after crushing and metering, adding leaching water of appropriate proportion, introducing steam to heat the arsenic alkali slag, and then performing stirring operation, at which time the servo motor is started, the servo motor drives the central axis to move, the central axis rotates and drives the separation component to gradually work, and through the setting of the separation component, the arsenic alkali slag is gradually rotated and extruded, and 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 through 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, and finally optimizing the antimony and arsenic separation effect by improving the removal of slag and changing the loss of antimony content.

[0007] 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 support legs are fixedly connected to the outer edge of the turntable, and the fan blades are fixedly connected to the top of the central axis located in the through cavity.

[0008] 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 slagging is required, which is time-consuming and labor-intensive, and the workload is large, the labor intensity is high, and there are problems of being time-consuming and labor-intensive. Using the embodiment of the present invention, the central axis is energized to rotate 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 legs, and the fan blades accelerate the blowing of the internal gas and discharge it through the side of the through cavity. When the legs rotate, they gradually drive the solid antimony-arsenic slag at the bottom of the leaching and separation kettle. Under the action of the rotating centrifugal force, the 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 and 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.

[0009] Furthermore, a dust separation component is provided on the outer side of the central axis, and the dust separation component includes a roller, a traction rope is rotatably connected to the side of the roller, a clamping plate is transmission-connected to the top of the traction rope, a connecting bar is fixedly connected to the side of the clamping plate close to the roller below, a cylinder is telescopically connected to the outer side of the connecting bar, a thin shaft is inserted into the top of the cylinder, a solid ring is fixedly connected to the middle of the leaching and separation kettle, a middle baffle is fixedly connected to the inner wall of the solid ring, a folding plate is folded at the bottom of the middle baffle, and the thin shaft passes through the sleeve frame.

[0010] Furthermore, the folding plate is fixedly connected to the fixed ring, the folding plate is supported on the middle baffle bar, the middle baffle bar is in the shape of an arc, and the cylinder is located below the fixed ring.

[0011] 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 antimony direct recovery rate. The rotation of the central axis gradually links the roller and moves with it. The rotation of the roller drags the traction rope, and the traction rope gradually deforms. The traction rope gradually tightens the card plate to drive it, and the card plate is dragged and displaced, and the card plate moves toward the card plate. The card plate pushes the connecting bar, and the connecting bar is gradually inserted into the cylinder when the card plate slides. The folding plate is folded upward and 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 indirectly transported upward. 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.

[0012] Furthermore, the leaching separation kettle includes a crushing assembly, which includes a filter cartridge. The inner wall of the filter cartridge is fixedly connected 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 fixedly connected with support columns, and the bottom ends of the support columns are rotatably connected with the long torsion plates. The center of the filter cartridge is sleeved on the outside of the central axis.

[0013] Furthermore, the support column is arranged to penetrate the long torsion plate, the long torsion plate is sleeved on the outside of the support column, and the filter cartridge is in the shape of a circular ring; during operation, before the antimony-arsenic separation, the ore with 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, 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, the filter cartridge is linked to move when the central shaft is driven, 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, and the long torsion plate at the bottom of the support column is gradually swung, and the long torsion plate wipes the bottom when it is swung. By wiping the bottom of the filter cartridge with the long torsion plate, the convenience of subsequent cleaning is facilitated, and the effect of crushing and ensuring internal cleaning is achieved; at the same time, the long torsion plate will contact the bottom of the support foot when it rotates, and the long torsion plate and the support foot rub to form vibration. Under the action of the vibration force, the separation of solid particles containing antimony and arsenic and the cleaning efficiency are accelerated.

[0014] Furthermore, the conveying assembly includes an inclined plate, which is in contact with 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 frame is slidably connected to a bow plate, the bow plate is arranged to penetrate the frame, and the telescopic spring is elastically connected to the leaching separation kettle.

[0015] Furthermore, the inclined plate is arranged to penetrate 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, it is necessary to add a solid catalyst manganese sulfate for catalytic treatment. When directly added, a chemical reaction is generated due to the combined heating treatment, which is easy to generate 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 axis is energized and moves, and the rotation of the central axis 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 in a direction close to the leaching separation kettle under the relative action of 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 is deformed and gradually and slowly compressed. The catalytic conveying plate slowly extends into 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, prevents the instantaneous generation of a large amount of smoke and dust from affecting the separation effect, and at the same time makes the central axis have the function of automatic compounding after rotating a certain number of circles.

[0016] The beneficial effects of the present invention are as follows:

[0017] 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 clamping 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 indirectly transported upward. 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.

[0018] 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 the subsequent cleaning, achieving the effect of crushing and ensuring the internal cleaning at the same time; at the same time, the long torsion plate will contact the bottom of the support foot when rotating, and the long torsion plate and the support foot 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

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Combination 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 component is arranged on the top of the placement plate 3, the conveying component 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 component is arranged in the cover plate 5, the separation component 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.

[0034] 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 stirring and mixing operations are performed. At this time, the servo motor is started, and the servo motor drives the central axis 52 to move. The central axis 52 rotates to drive the separation component to gradually work. By setting the separation component, the arsenic-alkali slag is gradually rotated and extruded, and after the arsenic-alkali slag is squeezed and slides to various directions and evenly spread out, it is automatically scraped, 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 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 content volatilized in the smoke, ensuring the maximum preservation of the antimony content, and finally optimizing the antimony-arsenic separation effect by improving the scraping and changing the loss of antimony content.

[0035] 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 mounted on the central axis 52, a turntable 53 is fixedly connected to the outer side 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, a support foot 54 is fixedly connected to the outer edge of the turntable 53, and the top of the central axis 52 is located in the through cavity 51 and is fixedly connected to the fan blades 55.

[0036] like Figure 1 , Figure 2 , Figure 5-Figure 7As shown, 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 has a large workload, high labor intensity, and is time-consuming and labor-intensive. Using the embodiment of the present invention, the central axis 52 is energized to rotate counterclockwise, and the central axis 52 rotates to link the turntable 53 to run, and the turntable 53 twists. The twisting of the turntable 53 gradually acts on the fan blades 55 and the support legs 54, and 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.

[0037] A dust separation component is arranged outside the central axis 52, and the dust separation component includes a rotating roller 521, a traction rope 522 is rotatably connected to the side of the rotating roller 521, and a clamping plate 523 is connected to the top of the traction rope 522. A connecting bar 524 is fixedly connected to the side of the clamping plate 523 near the rotating roller 521, and the connecting bar 524 is connected to the thin shaft 526. A notch corresponding to the connecting bar 524 is opened inside the cylinder 525, and the outer side of the connecting bar 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, and 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, and a folding plate 528 is folded and connected to the bottom of the middle baffle 529. The folding plate 528 is fixedly connected to the fixed ring 527, and the thin shaft 526 is arranged to penetrate the sleeve frame 4.

[0038] As shown in the figure, during operation, the amount of smoke is often large after heating, which causes the antimony alloy content to volatilize into the smoke, 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 to drive, and 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 clamping plate 523 slides, it will contact the folding plate 528, and the folding plate 528 will be folded upwards. 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 indirectly transported upwards. The interval treatment of the smoke by the folding plate 528 causes less volatilization of the antimony content contained in the internal smoke, ensuring that the value of the antimony direct recovery rate is not greatly reduced, thereby achieving the purpose of increasing the separation depth.

[0039] 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 fixedly connected to the inner wall of the filter cartridge 41. The bottom ends of the crushing pieces 42 are fixedly connected 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. The center of the filter cartridge 41 is sleeved on the outside of the central axis 52.

[0040] like Figure 5-Figure 6 As shown, during operation, before the separation of antimony and arsenic, 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, 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, the central shaft 52 is driven to move in conjunction with the filter cartridge 41, the filter cartridge 41 rotates and the crushing piece 42 rotates in conjunction, the crushing piece 42 crushes the antimony ore, and the crushing piece 42 drives the support column 43 to move synchronously. The long torsion plate 44 at the bottom end of the support column 43 is gradually swung, and 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 the subsequent cleaning, and achieves the effect of crushing while ensuring the internal cleaning; at the same time, the long torsion plate 44 will contact the bottom of the support foot 54 when rotating, and the long torsion plate 44 and the support foot 54 rub to form vibration. Under the action of the vibration force, the separation of the solid particles containing antimony and arsenic and the cleaning efficiency are accelerated.

[0041] The conveying assembly includes an inclined plate 31, the top of the inclined plate 31 is fixedly connected to the catalytic conveying plate 35, the inclined plate 31 is arranged to penetrate the sleeve frame 4, the top of the inclined plate 31 is movably fixedly connected to a rotating drum 32, the center of the rotating drum 32 is fixedly connected to a pressure sensor 33, the bottom end of the rotating drum 32 is fixedly connected to a filter tube 34, the bottom end of the filter tube 34 is slidably connected to the catalytic conveying plate 35, the side of the inclined plate 31 close to the leaching and separation kettle 2 is fixedly connected to a telescopic spring 37, the inside of the sleeve frame 4 is slidably connected to a bow plate 36, the bow plate 36 is arranged to penetrate the sleeve frame 4, and the telescopic spring 37 is elastically connected to the leaching and separation kettle 2.

[0042] like Figure 3-Figure 4 As shown, during operation, in the process of separating antimony and arsenic, solid catalyst manganese sulfate needs to be added for catalytic treatment. When directly added, a chemical reaction is generated due to the 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, and 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 moved synchronously. The inclined plate 31 contacts the wall, and the upper part of the inclined plate 31 is displaced toward the leaching separation kettle 2 under the relative action of force. The inclined plate 31 squeezes the telescopic spring 37 to move, and the arch plate 36 blocks the driving direction of the inclined plate 31. The telescopic spring 37 is deformed and gradually and slowly compressed. The catalytic conveying plate 35 is slowly extended into the leaching 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 slowly adding, preventing a large amount of smoke from being generated instantly to affect the separation effect, and at the same time, the central axis 52 has the function of automatic compounding after rotating a certain number of circles.

[0043] 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 the appropriate proportion of leaching water and the corresponding catalyst, steam is introduced to heat the arsenic alkali slag, and then the stirring and mixing operation is performed. Finally, the separation is completed by screening 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 is linked to run. The turntable 53 twists and 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 various directions to achieve the effect of rapid distribution, thereby improving the degree of automated operation. At the same time, 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 clamping plate 523 to drive it. The displacement of the clamping plate 523 pushes the connecting bar 524. Through the cooperation of the clamping plate 523, the middle baffle bar 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. The folding plate 528 treats the smoke at intervals to ensure that the antimony content contained in the internal smoke is less volatilized, and the value of the antimony direct recovery rate is not greatly reduced.

[0044] When the original antimony-arsenic alloy material needs to be crushed before separation, the central shaft 52 is driven to move with the filter cartridge 41, the filter cartridge 41 rotates and the crushing piece 42 rotates, the crushing piece 42 crushes the antimony ore, and the crushing piece 42 cooperates with the support column 43 to make the long torsion plate 44 wipe the bottom synchronously, so as to ensure the cleanliness of the bottom while ensuring crushing, which is convenient for subsequent cleaning.
