Description

Technical Field

[0001] The invention relates to the technical field of preparation of duplex white carbon black, in particular to a preparation device of duplex white carbon black. Background Art

[0002] With the rapid development of the automobile industry, more and more waste tires are being discarded at will, causing pollution. In order to solve these problems, my country has also been accelerating the treatment of tires in recent years. The main way our country treats tires is to produce recycled rubber. Although my country is a major automobile country, it is very short of rubber resources. Recycled rubber can make up for this gap a little bit, and it can also be exported.

[0003] The composition of tire rubber powder processed from waste tires is relatively complex, mainly including natural rubber or synthetic rubber, sulfur, white carbon black, carbon black, etc. The advent of waste tire thermal cracking and refining equipment can perfectly process waste tires to obtain valuable products such as tire oil, carbon black and steel wire, and the processing process is environmentally friendly and harmless.

[0004] Pyrolysis refers to an irreversible thermochemical reaction that uses high temperature to crack the organic matter in waste tires under anaerobic or anoxic conditions, escaping volatile products and forming solid coke. Waste tires or waste tire blocks are heated for catalytic cracking to obtain products such as fuel oil, carbon black slag and steel wire. The small amount of combustible gas produced during the cracking process is used by the cracking system. The cracking method can achieve the recycling of waste tires.

[0005] In addition, with the requirements of green tires and tire labeling, the use of white carbon black in tires has gradually increased, especially in scrapped passenger car tires, where the content of white carbon black is higher, accounting for about 20-35% of the tread rubber powder. The annual production capacity of white carbon black is 2 million tons, which is a large gap. The content of silicon dioxide in the carbon black slag after the cracking of such tires is high, and the recovery of silicon dioxide is very meaningful for environmental protection and circular economy.

[0006] The patent with the patent announcement number CN207944048U discloses a device for preparing ultrafine white carbon black, including a raw material silo, a feeder, an ultrafine device, an induced draft fan, a computer control system, a finished product silo, a vacuum automatic packaging machine, and a packaging bag. The characteristics are that the raw material inlet is arranged above the raw material silo, the feed port of the feeder is connected to the outlet of the raw material silo, the discharge port of the feeder is connected to the feed port of the ultrafine device, one end of the induced draft fan is connected to the discharge port of the ultrafine device, and the other end is connected to the finished product silo, and the vacuum automatic packaging machine is arranged at the discharge port of the finished product silo. The feeder, the ultrafine device, the induced draft fan and the vacuum automatic packaging machine are all connected to the computer control system and controlled by the computer control system. The patent has the advantages of simple operation, not only automatic packaging, reducing dust pollution, but also obtaining ultrafine white carbon black with adjustable particle size, improving product added value and expanding application areas.

[0007] However, the device still has some shortcomings: the device can reduce dust pollution and obtain ultrafine white carbon black with adjustable particle size, but the carbon black slag obtained by direct cracking and crushing of waste tires is directly used in rubber products without treatment, which is prone to problems such as poor performance, large performance fluctuations, and low structure. At this time, the carbon black slag needs to be acidified to remove heavy metals in the carbon black slag to improve the performance of rubber products. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides a device for preparing duplex silica, which solves the problems raised in the above-mentioned background technology.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: a preparation device for dual-phase white carbon black, comprising a separation barrel, a motor is arranged at the center of the top of the separation barrel, a liquid injection pipe is arranged on the right side of the top of the separation barrel, the liquid injection pipe is connected to the inside of the separation barrel, a connecting pipe is arranged on the right side of the separation barrel, a centrifugal atomization tower is arranged on the right side of the connecting pipe, a sander assembly is arranged on the left side of the separation barrel, a funnel is arranged on the top of the sander assembly, a temperature control assembly is arranged on the outer wall of the sander assembly, and the sander assembly is connected to the separation barrel, a extraction assembly is arranged on the front of the separation barrel, an injection assembly is arranged on the back of the separation barrel, and the bottom of the inner wall of the separation barrel is provided with a suction assembly. A vertical rod is rotatably installed, the top of the vertical rod passes through and is fixedly installed at the bottom of the motor output end, a hollow filter barrel is fixedly installed at the center of the outer wall of the vertical rod, a plurality of connecting rods are fixedly installed above the outer wall of the vertical rod, and the plurality of connecting rods are equidistantly distributed on the outer wall of the vertical rod, a heating component is fixedly installed on the end of the connecting rod away from the center of the separation barrel, an elastic telescopic rod is passed through and fixedly installed on the outer wall of the connecting rod, the elastic telescopic rod is composed of a fixed end and a telescopic end, an interception filter plate is fixedly installed at the bottom of the telescopic end of the elastic telescopic rod, a plurality of resistance blocks are fixedly installed at the top edge of the interception filter plate, and the plurality of resistance blocks are equidistantly distributed on the top of the interception filter plate, and the inner wall of the separation barrel is equidistant and Several semi-arc blocks are fixedly installed. The carbon black produced after cracking enters the inside of the sander assembly through the funnel. The raw material is crushed to 1-5 microns to form carbon black slag through the centrifugal force of the high-speed rotating grinding balls inside the sander assembly. At the same time, the temperature of the sander assembly during the crushing of carbon black is controlled at 250-400℃ by the temperature control component. The crushed carbon black slag is sent to the separation barrel by the sander assembly, and hydrochloric acid is added to the separation barrel through the injection pipe. The motor is started, and the output end of the motor drives the vertical rod to rotate, and the vertical rod drives the hollow filter barrel to rotate. The hollow filter barrel collects and receives the carbon black slag, and the rotation of the hollow filter barrel drives the carbon black slag to rotate and mix with the hydrochloric acid. When the filter is fully in contact, when the vertical rod drives the connecting rod to rotate, the connecting rod drives the heating component to rotate and rotates and heats the inside of the separation barrel, thereby increasing the temperature of the carbon black slag when it contacts the hydrochloric acid; the connecting rod drives the elastic telescopic rod to rotate, and the telescopic end of the elastic telescopic rod drives the interception filter plate to rotate. When the interception filter plate rotates, the resistance block is driven to rotate. When the resistance block rotates, its own arc surface will resist the semi-arc block to generate a resistance force. At this time, the separation barrel limits the semi-arc block to cause the resistance block to generate a downward force. When the resistance block presses the interception filter plate to move downward, it pulls the telescopic end of the elastic telescopic rod to move synchronously. After that, the interception filter plate is reset by the reset elastic force of the elastic telescopic rod. This reciprocating process enables the interception filter plate to reciprocate up and down;After the hydrochloric acid reacts with the carbon black slag for thirty minutes, the hydrochloric acid is extracted from the separation barrel through the extraction component, and then the alkaline solution is injected into the separation barrel through the injection component. The carbon black slag washed with hydrochloric acid is dissolved by the alkaline solution, and the dissolving temperature is controlled at 180 degrees Celsius. Then, the regenerated carbon black mixed liquid formed by mixing the carbon black slag and the dissolving liquid is sent to the centrifugal atomization tower through the connecting pipe for centrifugal drying to form a two-phase white carbon black. ;

[0010] According to the above technical solution, the inner wall of the intercepting filter plate penetrates and is slidably installed on the outer wall of the vertical rod, and the intercepting filter plate is located above the hollow filter barrel. Several of the semi-arc blocks are located on the movement trajectory of the resistance block, and an anti-deposition device is provided under the intercepting filter plate to prevent carbon black slag from being deposited on the bottom of the inner wall of the hollow filter barrel and unable to react with hydrochloric acid.

[0011] According to the above technical scheme, the anti-deposition device includes a sliding ring, a plurality of horizontal plates, a round rod and a conical mesh plate. The inner wall of the sliding ring passes through and is slidably installed on the outer wall of the vertical rod. The top of the sliding ring is fixedly installed on the bottom of the intercepting filter plate. The plurality of horizontal plates are equidistant and fixedly installed on the outer wall surface of the sliding ring. The top of the round rod is fixedly installed on the bottom of the horizontal plate. The inside of the conical mesh plate passes through and is fixedly installed on the outer wall surface of the round rod. When the intercepting filter plate rotates and moves downward, it drives the sliding ring to move synchronously. When the sliding ring rotates along the outer wall of the vertical rod and slides downward, it drives the horizontal plate to move synchronously. The horizontal plate drives the round rod to move synchronously. The round rod drives the conical mesh plate to move synchronously.

[0012] According to the above technical scheme, the anti-deposition device also includes a hinged plate, a wave plate, a groove rod and a thin plate. The top of the hinged plate is hinged to the bottom of the horizontal plate, the top of the wave plate is hinged to the bottom of the hinged plate, the outer walls at both ends of the groove rod are fixedly installed on the inner wall of the circular groove in the wave plate, and the bottom of the thin plate is fixedly installed on the top of the outer wall of the groove rod. When the horizontal plate moves downward, it drives the hinged plate to move synchronously. The bottom of the hinged plate is resisted by the wave plate. At this time, the hinge axis of the hinged plate starts to rotate, and the hinged plate moves in an arc with its own hinge axis as the axis, and the hinged plate pushes the wave plate to slide away from the center of the hollow filter barrel, the wave plate drives the groove rod to move synchronously, and the groove rod drives the thin plate to move synchronously.

[0013] According to the above technical solution, the bottom of the corrugated plate contacts the bottom of the inner wall of the hollow filter barrel, a zigzag groove is provided inside the corrugated plate, and an anti-mixing device for fully separating the carbon black slag and hydrochloric acid is provided on the inner side of the corrugated plate.

[0014] According to the above technical scheme, the anti-mixing device includes a plurality of U-shaped plates, a rotating wheel, a cross bar and a plurality of driving plates. The bottom of the plurality of U-shaped plates near one end of the inner wall of the separation barrel is fixedly installed on the top of the wave plate. The rotating wheel is rotatably installed on the inner wall of the U-shaped plate near the center of the wave plate. The outer walls at both ends of the cross bar are fixedly installed on the inner wall of the rotating wheel. The plurality of driving plates are fixedly and equidistantly installed on the outer wall surface of the cross bar. When the wave plate slides, it drives the U-shaped plate to move synchronously, and the U-shaped plate drives the rotating wheel to move synchronously. When the rotating wheel slides, it contacts the bottom of the inner wall of the hollow filter barrel and generates friction. The rotating wheel starts to rotate due to the friction. When the rotating wheel rotates, the sliding friction between the wave plate and the bottom of the inner wall of the hollow filter barrel is converted into rolling friction to reduce wear. When the rotating wheel rotates, the cross bar rotates, and the cross bar drives the driving plate to rotate.

[0015] According to the above technical solution, the several U-shaped plates are symmetrically distributed around the axis of the wave plate, the outer wall of the runner contacts the bottom of the inner wall of the hollow filter barrel, the outer wall of the cross bar passes through the interior of the U-shaped plate, and a reciprocating spiral groove is opened at the center of the outer wall of the cross bar.

[0016] According to the above technical scheme, the anti-mixing device also includes a push plate, a push plate, a sliding plate, a slotted arc piece, a gathering plate and a plurality of cylinders, the push plate passes through and is slidably installed on the reciprocating spiral groove on the outer wall of the cross bar, the outer wall of the push plate is slidably installed on the outer wall of the driving plate, the end of the push plate close to the center of the cross bar is located on the movement trajectory of the outer wall of the push plate, the end of the sliding plate close to the center of the cross bar is fixedly installed on the outer wall of the push plate, the outer wall of the sliding plate is slidably connected to the outer wall of the driving plate, the slotted arc piece is fixedly installed between the side of the sliding plate away from the center of the cross bar and the outer wall of the driving plate, the gathering plate close to the center of the cross bar One end is slidably installed on the outer wall of the push plate by a spring, and the outer wall of the gathering plate is provided with a plurality of grooves, and the plurality of cylinders are fixedly installed at the edge of the outer wall of the driving plate, and the outer wall of the cylinder Located on the movement trajectory of the gathering plate groove, the cross bar rotates through the reciprocating spiral groove on its own outer wall to limit the built-in block of the push plate, and the built-in block of the push plate continuously resists the inner wall of the reciprocating spiral groove. Therefore, when the cross bar rotates, the push plate can slide back and forth along its outer wall, and during the sliding process of the push plate, it resists the push plate to move away from the center of the cross bar, and the push plate drives the sliding plate to slide synchronously along the outer wall of the driving plate. During the sliding process of the sliding plate, the grooved arc piece will resist and deform. At this time, the curvature of the grooved arc piece increases. When the sliding plate is reset, the grooved arc piece is pulled to restore. At the same time, the sliding plate drives the gathering plate to slide synchronously along the outer wall of the driving plate. When the gathering plate slides, its own groove contacts the outer wall of the cylinder to generate a resistance force, and the gathering plate slides along the outer wall of the driving plate toward the center of the driving plate through the resistance force, and then the gathering plate is reset by the spring.

[0017] The present invention provides a device for preparing duplex white carbon black, which has the following beneficial effects: (1) The present invention cooperates with a vertical rod, a hollow filter barrel, a connecting rod, a heating component, an elastic telescopic rod, an intercepting filter plate, a resistance block and a semi-arc block. By adding hydrochloric acid into the device, the hydrochloric acid reacts with the metal ions remaining in the carbon black slag, thereby removing the metal ions in the carbon black slag, preventing the carbon black slag from being directly used in rubber products without being treated, and avoiding problems such as poor performance and large performance fluctuations. At the same time, the intercepting filter plate that reciprocates downwardly flaps effectively limits the movement range of the carbon black slag, preventing the carbon black slag from being separated from the hollow filter barrel in large quantities under the centrifugal force of the vertical rod rotation, and preventing a large amount of carbon black slag from being simultaneously separated from the separation barrel in the process of extracting hydrochloric acid in the later stage, causing a waste of raw materials.

[0018] (2) The present invention sets an anti-deposition device, and cooperates with an intercepting filter plate, a sliding ring, a horizontal plate, a round rod, a conical mesh plate, a hinged plate, a wave plate, a groove rod and a thin plate to promote the conical mesh plate to guide the carbon black slag and hydrochloric acid inside the hollow filter barrel, and the conical mesh plate reciprocates up and down to disperse the agglomerated carbon black slag inside itself, so as to avoid the agglomeration of the carbon black slag when it is impacted by hydrochloric acid, which makes it difficult for part of its area to be washed, resulting in residual metal ions, and promotes the wave plate to slide and shovel up the carbon black slag attached to the bottom of the inner wall of the hollow filter barrel when it slides, and then through the turbulence effect of the groove rod and the thin plate during movement, the floating carbon black slag is dynamically evacuated, thereby ensuring the loose uniformity of the carbon black slag and preventing the occurrence of secondary attachment.

[0019] (3) The present invention effectively expands the range of motion of the driving plate inside the hollow filter barrel by setting up an anti-mixing device through the coordination of a wave plate, a U-shaped plate, a rotating wheel, a cross bar, a driving plate, a push plate, a push plate, a sliding plate, a slotted arc sheet, a gathering plate and a cylinder, so as to promote the driving plate to rotate and stir the hydrochloric acid during the extraction process of the hydrochloric acid inside the separation barrel, and to rotate and separate the carbon black slag mixed in the hydrochloric acid to avoid the two being mixed and discharged synchronously, thereby reducing the purity of the hydrochloric acid liquid; at the same time, the sliding of the gathering plate and the deformation and reset of the slotted arc sheet are promoted to cooperate with each other, thereby increasing the stirring force of the driving plate on the hydrochloric acid and the carbon black slag during the rotation process, further ensuring the solid-liquid separation effect, and at the same time preventing the carbon black slag from adhering to the outer wall of the driving plate when it contacts, thereby increasing the degree of wear of parts.

An interception filter plate 11 is fixedly installed at the bottom of the telescopic end of the elastic telescopic rod 10, and a plurality of abutment blocks 12 are fixedly installed at the top edge of the interception filter plate 11. The plurality of abutment blocks 12 are evenly distributed on the top of the interception filter plate 11, and a plurality of semi-arc blocks 13 are evenly and fixedly installed on the inner wall of the separation barrel 1. By adding hydrochloric acid to the device, the hydrochloric acid reacts with the metal ions remaining in the carbon black slag, and then the metal ions in the carbon black slag can be removed, so as to prevent the carbon black slag from being directly used in rubber products without treatment, and avoid problems such as poor performance and large performance fluctuations; through the above cooperation, the interception filter plate 11 that flaps reciprocatingly downward is used to effectively limit the movement range of the carbon black slag, so as to prevent the carbon black slag from escaping from the hollow filter barrel 7 in large quantities under the centrifugal force of the rotation of the vertical rod 6, and to prevent the large amount of carbon black slag from being synchronously escaping from the separation barrel 1 in the process of extracting hydrochloric acid in the later stage, resulting in a waste of raw materials.

[0024] The inner wall of the intercepting filter plate 11 passes through and is slidably installed on the outer wall of the vertical rod 6, and the intercepting filter plate 11 is located above the hollow filter barrel 7. Several semi-arc blocks 13 are located on the movement trajectory of the resistance block 12. An anti-deposition device 4 is provided below the intercepting filter plate 11 to prevent carbon black slag from being deposited on the bottom of the inner wall of the hollow filter barrel 7 and unable to react with hydrochloric acid.

[0025] When in use, the carbon black produced after cracking enters the sander component 3 through the funnel, and the raw material is crushed to 1-5 microns by the centrifugal force of the high-speed rotating grinding balls in the sander component 3 to form carbon black slag. At the same time, the temperature of the sander component 3 during the crushing process of the carbon black is controlled at 200-450°C by the temperature control component 31. The crushed carbon black slag is sent to the separation barrel 1 by the sander component 3, and hydrochloric acid is added to the separation barrel 1 through the injection pipe 101. The motor is started, and the output end of the motor drives the vertical rod 6 to rotate, and the vertical rod 6 drives the hollow filter barrel 7 to rotate. The hollow filter barrel 7 collects and receives the carbon black slag, and When the hollow filter barrel 7 rotates, it drives the carbon black slag to rotate and fully contact with the hydrochloric acid. At the same time, when the vertical rod 6 drives the connecting rod 8 to rotate, the connecting rod 8 drives the heating component 9 to rotate and rotates and heats the inside of the separation barrel 1, thereby increasing the temperature of the carbon black slag when it contacts with the hydrochloric acid. By adding hydrochloric acid into the device, the hydrochloric acid reacts with the metal ions remaining in the carbon black slag, thereby removing the metal ions in the carbon black slag, preventing the carbon black slag from being directly used in rubber products without being treated, and avoiding problems such as poor performance and large performance fluctuations. The connecting rod 8 drives the elastic telescopic rod 10 to rotate, and the telescopic end of the elastic telescopic rod 10 drives the interception filter plate 11 to rotate. When the plate 11 rotates, it drives the resistance block 12 to rotate. When the resistance block 12 rotates, its own arc surface will resist the semi-arc block 13 to generate a resistance force. At this time, the separation barrel 1 limits the semi-arc block 13 to cause the resistance block 12 to generate a downward movement force. When the resistance block 12 presses the interception filter plate 11 to move downward, it pulls the telescopic end of the elastic telescopic rod 10 to move synchronously. Then, the interception filter plate 11 is reset by the reset elastic force of the elastic telescopic rod 10, and the reciprocating movement of the interception filter plate 11 is enabled. The above cooperation relies on the reciprocating downward flapping interception filter plate 11 to effectively limit the movement range of the carbon black slag, preventing the carbon black slag from rotating centrifugally on the vertical rod 6 A large amount of carbon black slag is separated from the hollow filter barrel 7 under the force, so as to prevent a large amount of carbon black slag from being simultaneously separated from the separation barrel 1 during the later extraction of hydrochloric acid, causing a waste of raw materials; after the hydrochloric acid and the carbon black slag react for thirty minutes, the hydrochloric acid is extracted from the separation barrel 1 through the extraction component 32, and then the alkaline solution is injected into the separation barrel 1 through the injection component 33, and the carbon black slag washed with hydrochloric acid is dissolved by the alkaline solution, and the dissolution temperature is controlled at 180 degrees Celsius, and then the regenerated carbon black mixed liquid formed by mixing the carbon black slag and the dissolving liquid is sent to the centrifugal atomization tower 2 through the connecting pipe 102 for centrifugal drying to form a two-phase white carbon black.

[0026] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-deposition device 4; The anti-deposition device 4 includes a sliding ring 41, a plurality of transverse plates 42, a round rod 43 and a conical mesh plate 44. The inner wall of the sliding ring 41 passes through and is slidably installed on the outer wall of the vertical rod 6. The top of the sliding ring 41 is fixedly installed on the bottom of the intercepting filter plate 11. The plurality of transverse plates 42 are equidistant and fixedly installed on the outer wall surface of the sliding ring 41. The top of the round rod 43 is fixedly installed on the bottom of the transverse plate 42. The inside of the conical mesh plate 44 passes through and is fixedly installed on the outer wall surface of the round rod 43. Through the above cooperation, the conical mesh plate 44 is enabled to guide the carbon black slag and hydrochloric acid inside the hollow filter barrel 7, and the conical mesh plate 44 reciprocates up and down to disperse the agglomerated carbon black slag inside itself, so as to avoid agglomeration of the carbon black slag when it is impacted by hydrochloric acid, which makes it difficult for part of its area to be washed, resulting in residual metal ions.

[0027] The anti-deposition device 4 also includes a hinged plate 45, a wave plate 46, a groove rod 47 and a thin plate 48.

Through the above cooperation, the wave plate 46 is prompted to slide and shovel up the carbon black slag attached to the bottom of the inner wall of the hollow filter barrel 7 when sliding, and then the floating carbon black slag is dynamically evacuated through the turbulence effect of the groove rod 47 and the thin plate 48 during movement, thereby ensuring the loose uniformity of the carbon black slag and preventing the occurrence of secondary attachment.

The horizontal plate 42 drives the round rod 43 to move synchronously. The round rod 43 drives the conical mesh plate 44 to move synchronously. Through the above cooperation, the conical mesh plate 44 guides the carbon black slag and hydrochloric acid inside the hollow filter barrel 7, and the conical mesh plate 44 reciprocates up and down to disperse the agglomerated carbon black slag inside itself, so as to avoid the agglomeration of the carbon black slag when it is impacted by hydrochloric acid, which makes it difficult for part of its area to be washed, resulting in residual metal ions; when the horizontal plate 42 moves downward, it drives the hinged plate 45 to move synchronously. The bottom of the hinged plate 45 is resisted by the wave plate 46. At this time, the hinge axis of the hinged plate 45 starts to rotate, and the hinged plate 45 moves in an arc shape with its own hinge axis as the axis, and the hinged plate 45 pushes the wave plate 46 to slide away from the center of the hollow filter barrel 7. The wave plate 46 drives the groove rod 47 to move synchronously, and the groove rod 47 drives the thin plate 48 to move synchronously. Through the above cooperation, the wave plate 46 slides and shovels up the carbon black slag attached to the bottom of the inner wall of the hollow filter barrel 7 when sliding, and then the floating carbon black slag is dynamically evacuated through the turbulence effect of the groove rod 47 and the thin plate 48 during movement, thereby ensuring the loose uniformity of the carbon black slag and preventing the occurrence of secondary attachment.

The outer walls of both ends of the cross bar 53 are fixedly mounted on the inner wall of the rotating wheel 52. The plurality of driving plates 54 are fixedly and equidistantly mounted on the outer wall surface of the cross bar 53. The above coordination effectively expands the range of movement of the driving plate 54 inside the hollow filter barrel 7, prompting the driving plate 54 to rotate and stir the hydrochloric acid during the extraction process of the hydrochloric acid inside the separation barrel 1, and the carbon black slag mixed in the hydrochloric acid is rotated and separated to avoid the mixing and synchronous discharge of the two, thereby reducing the purity of the hydrochloric acid liquid.

[0032] The anti-mixing device 5 also includes a push plate 55, a push plate 56, a sliding plate 57, a slotted arc piece 58, a gathering plate 59 and a plurality of cylinders 510. The push plate 55 penetrates the interior and is slidably mounted on the reciprocating spiral groove on the outer wall of the cross bar 53. The outer wall of the push plate 56 is slidably mounted on the outer wall of the driving plate 54. The end of the push plate 56 close to the center of the cross bar 53 is located on the movement track of the outer wall of the push plate 55. The end of the sliding plate 57 close to the center of the cross bar 53 is fixedly mounted on the outer wall of the push plate 56. The outer wall of the sliding plate 57 is slidably connected to the outer wall of the driving plate 54. The slotted arc piece 58 is fixedly mounted between the side of the sliding plate 57 away from the center of the cross bar 53 and the outer wall of the driving plate 54. The gathering plate 59 is installed on the outer wall of the push plate 56 by a spring for vertical sliding at one end near the center of the cross bar 53, and a plurality of grooves are provided on the outer wall of the gathering plate 59. A plurality of cylinders 510 are fixedly installed on the edge of the outer wall of the driving plate 54, and the outer wall of the cylinder 510 is located on the movement trajectory of the groove of the gathering plate 59. The above cooperation promotes the mutual cooperation between the sliding of the gathering plate 59 and the deformation and reset of the slotted arc sheet 58, thereby increasing the stirring force of the driving plate 54 on the hydrochloric acid and the carbon black slag during the rotation process, further ensuring the solid-liquid separation effect, and preventing the carbon black slag from adhering to the outer wall of the driving plate 54 when it contacts, thereby increasing the degree of wear and tear of parts.

[0033] When in use, the wave plate 46 drives the U-shaped plate 51 to move synchronously when sliding, and the U-shaped plate 51 drives the rotating wheel 52 to move synchronously. When the rotating wheel 52 slides, it contacts the bottom of the inner wall of the hollow filter barrel 7 and generates friction. The rotating wheel 52 starts to rotate due to the friction. When the rotating wheel 52 rotates, the sliding friction between the wave plate 46 and the bottom of the inner wall of the hollow filter barrel 7 is converted into rolling friction, thereby reducing wear. When the rotating wheel 52 rotates, the cross bar 53 rotates, and the cross bar 53 drives the driving plate 54 to rotate. Through the above cooperation, the activity range of the driving plate 54 inside the hollow filter barrel 7 is effectively expanded, so that the driving plate 54 is caused to rotate and stir the hydrochloric acid during the extraction process of the hydrochloric acid inside the separation barrel 1, and the carbon black slag mixed in the hydrochloric acid is rotated and separated to avoid the mixing and synchronous discharge of the two, thereby reducing the purity of the hydrochloric acid liquid; when the cross bar 53 rotates, the reciprocating spiral groove on the outer wall of the cross bar 53 limits the built-in block of the push plate 55, and the built-in block of the push plate 55 constantly resists the inner wall of the reciprocating spiral groove, so when the cross bar 53 rotates, the push plate 55 can slide back and forth along its outer wall. The push plate 55 moves in a direction away from the center of the cross bar 53 during the sliding process, and the push plate 56 drives the sliding plate 57 to slide synchronously along the outer wall of the driving plate 54. During the sliding process, the sliding plate 57 will resist the slotted arc piece 58 and deform. At this time, the arc of the slotted arc piece 58 increases. When the sliding plate 57 is reset, the slotted arc piece 58 is pulled to restore. At the same time, the sliding plate 57 drives the gathering plate 59 to slide synchronously along the outer wall of the driving plate 54. When the gathering plate 59 slides, its own groove contacts the outer wall of the cylinder 510 A resistance force is generated, and the gathering plate 59 slides along the outer wall of the driving plate 54 toward the center of the driving plate 54 through the resistance force. Then the gathering plate 59 is reset by the spring. The above cooperation promotes the sliding of the gathering plate 59 and the deformation and reset of the slotted arc plate 58 to cooperate with each other, thereby increasing the stirring force of the driving plate 54 on the hydrochloric acid and the carbon black slag during the rotation process, further ensuring the solid-liquid separation effect, and preventing the carbon black slag from adhering to the outer wall of the driving plate 54 when it contacts, thereby increasing the degree of wear and tear of parts.
