Description

Technical Field

[0001] This invention relates to the field of carbon black production and processing, and in particular to an impurity screening and processing device for carbon black production and processing. Background Technology

[0002] Carbon black is a black powdery substance produced by the incomplete combustion or pyrolysis of carbon-containing raw materials (such as petroleum, natural gas, and coal). It is widely used in rubber, plastics, inks, coatings, and other fields. The following section discusses its production raw materials, processes, equipment, applications, and development trends.

[0003] In the carbon black production and processing, impurity screening is a crucial step in ensuring product purity and performance. Impurities in carbon black mainly include mechanical impurities, solid particulate impurities, solid mineral raw material impurities, and carbon black materials with varying particle sizes. Therefore, carbon black needs to be screened to select carbon black with the appropriate particle size, while also removing other impurities. However, current carbon black screening methods are not convenient for multi-stage flexible screening, and impurities tend to remain within the screening structure after screening, reducing the passage of qualified carbon black during continuous screening and thus decreasing screening efficiency.

[0004] Publication number CN118788586B discloses an impurity screening and treatment device for carbon black production and processing, and its impurity removal process. The device includes a housing with a feed inlet at the top. A mounting frame is fixedly connected to the inner wall of the housing, and a second sliding shaft is fixedly connected to the inner wall of the mounting frame. A screen plate is slidably connected to the outer wall of the second sliding shaft. By providing this device and its impurity removal process, during carbon black screening, a first magnet, in conjunction with the screen plate, separates carbon black from metallic impurities. An electric telescopic rod, in conjunction with a receiving assembly, removes the magnetic force from the screen plate, allowing metallic impurities to exit the housing. A guide plate diverts the carbon black entering the housing, ensuring it falls evenly and dispersedly onto the screen plate, preventing carbon black accumulation and clogging. Furthermore, triangular protrusions delay the sliding time of the carbon black on the screen plate.

[0005] While the aforementioned technical solutions can avoid accumulation and improve the throughput of the sieve plate, they cannot achieve multi-stage flexible sieving of carbon black with different particle sizes. Furthermore, in practical use, carbon black powder easily generates dust, polluting the working environment. Therefore, a carbon black production and processing impurity sieving and treatment device is proposed. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention proposes an impurity screening and processing device for carbon black production and processing. It can flexibly perform multi-stage screening of carbon black according to needs, and can clean impurities in a timely manner, improve the passivity of the screen cylinder to improve screening efficiency, and has good sealing stability and is not prone to dust generation.

Multiple layers of screen cylinders are fitted onto the upper end of the sleeve cylinder seat. Side frames are connected to both sides of each screen cylinder. A screen mesh is installed inside each screen cylinder. A rotating cylinder is rotatably mounted inside each screen cylinder, and multiple arc-shaped paddles are arrayed at the lower end of the rotating cylinder.

[0010] Preferably, electric guide rails are installed on both sides of the slide frame, and two slide frames are provided and slidably installed on the electric guide rails on both sides of the slide frame. An insertion hole is provided at the upper end of the side frame, and an insertion rod that is inserted into the insertion hole is connected to the lower end of the side frame.

[0011] Preferably, the drive assembly includes a worm, a first gear, a rotating shaft, and a ratchet. The two ends of the worm are rotatably mounted on the inner walls of both sides of the groove and extend through the groove into the screen cylinder, where they mesh with the worm gear. The first gear is rotatably mounted on the inner walls of both sides of the groove. The rotating shaft is rotatably mounted inside the groove. The outer surfaces of both ends of the groove and the outer surfaces of both ends of the worm are fitted with second gears. The ratchet is fitted at both ends of the rotating shaft and is positioned on one side away from the second gears on both sides. The first gear is located between the two second gears on the worm and the rotating shaft and meshes with the second gears on both sides respectively.

[0012] Preferably, the inner walls on both sides of the groove are provided with an opening through the side frame, and the two ends of the rotating shaft extend through the opening to the outside of the side frame, with a ratchet fitted at the outer extension end.

[0013] Preferably, the adjustment assembly includes a slide, a mounting plate, a guide rod frame, and a claw. The slide is slidably disposed on the outside of the collection frame and extends through the collection frame into it, with the mounting plate connected to the extended end inside the collection frame. The guide rod frame is connected to the mounting plate. The scraper is slidably sleeved on the outside of the guide rod frame, and a second spring sleeved on the outside of the guide rod frame is connected between the scraper and the end of the guide rod frame. The claw is connected to the scraper, and the clamping plate and the claw engage in a clamping sleeve.

[0014] Preferably, both sides of the collection frame are connected to a sliding rod frame, and the two sides of the sliding rod frame are slidably sleeved on the outside of the sliding rod frame. A spring three sleeved on the outside of the sliding rod frame connects the sliding rod frame and the collection frame.

[0015] Preferably, the linkage component includes a limiting slot, a ratchet, a first spring, and a pressure plate. The limiting slot is formed on the slide frame. One end of the ratchet is slidably disposed in the limiting slot, and the other end passes through the limiting slot to the outside of the slide frame. The outer extension end of the ratchet is engaged with a ratchet wheel on one side. A second spring is connected between one end of the ratchet in the limiting slot and the inner wall of the limiting slot. The pressure plate is connected to the slide frame and is arranged in multiple layers. Each layer of the pressure plate cooperates with and abuts against the upper end of the sliding frame on the corresponding layer of the collection frame.

[0016] Preferably, the outer side of the side frame is provided with a slot, and a plurality of limiting trapezoidal blocks are connected at equal intervals on the slide. Each limiting trapezoidal block is provided with a corresponding screen cylinder, and both sides of the limiting trapezoidal block are rotatably connected to a rotating plate through a spring hinge. The end of each rotating plate away from the limiting trapezoidal block slides and abuts against the inner wall of its respective slot.

[0017] The beneficial effects of this invention are: 1. The technical solution of the present invention arranges multiple layers of screen cylinders under the guide hopper cover, with each screen cylinder interlocking with the others. Then, by controlling the expansion joint to retract, the guide hopper cover is moved down, pressing the uppermost screen cylinder. This allows for the installation of multiple layers of screen cylinders, enabling multi-stage screening. Each layer of screen cylinder has a different mesh size, with the mesh size increasing from top to bottom. This achieves multi-stage screening, separating carbon black of different particle sizes and also screening out impurities. 2. The technical solution of this invention controls the sliding frame to slide up and down on the electric guide rail of the slide frame 25. Through the meshing of the ratchet and ratchet wheel, the ratchet wheel rotates, which in turn drives the worm gear to rotate via the rotating shaft, gear two, and gear one. The meshing of the worm gear and worm wheel then drives the rotating drum to rotate. This causes multiple arc-shaped paddles arrayed at the lower end of the rotating drum to rotate around the center of the drum. This allows impurities or large-diameter carbon black particles that have been vibrated and screened on the vibrating table and are located on the outer edge of the screen drum to be moved by the arc-shaped paddles and collected through the opening two. The material is collected into the collection frame. At the same time, the ratchet slides in the limiting groove of the sliding frame. Therefore, when the ratchet moves up, it can drive the ratchet to rotate. When it moves down, the ratchet will compress the first spring and retract into the limiting groove, not engaging with the ratchet. This allows the ratchet to rotate only in one direction, and thus the drum can also rotate only in one direction. This drives the arc-shaped paddle to push the impurities or large-diameter carbon black particles through the second opening into the collection frame, preventing impurities or large-diameter carbon black particles from accumulating on the screen of the screen cylinder and causing blockage. This improves the throughput and screening efficiency of the screen cylinder. 3. The technical solution of this invention, through the up-and-down movement of the sliding frame, can also drive the pressure plate to move up and down. When the pressure plate moves down, it can abut against the sliding frame, thereby driving the sliding frame and the mounting plate to move down, and then driving the scraper to move down and fit against the bottom of the collection frame. At this time, the claws on the mounting plate will lock into position with the card plate connected to the output end of the telescopic component two, thereby controlling the telescopic component two to retract, which can drive the scraper to slide along the guide rod frame connected to the mounting plate, thereby transferring the impurities or large-diameter carbon black collected in the collection frame to the cleaning box, avoiding the accumulation of impurities or large-diameter carbon black in the collection frame. At the same time, the bottom of the cleaning box is provided with a discharge port, so that the impurities or large-diameter carbon black falling through the discharge port can be transferred by setting a collection bag or arranging a conveying mechanism at the bottom of the cleaning box, thereby improving the cleaning effect.

[0020] The following will be combined with the appendix Figure 1 To be continued Figure 9 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: like Figures 1-9As shown, the present invention discloses an impurity screening and processing device for carbon black production and processing, including a vibrating table 1, a tray 2 installed on the vibrating table 1, a sleeve cylinder seat 6 installed at the upper end of the tray 2, and a feeding funnel 5 opened at the lower end. A multi-layer screen cylinder 7 is fitted at the upper end of the sleeve cylinder seat 6. Side frames 8 are connected to both sides of each screen cylinder 7. A screen mesh 11 is installed inside the screen cylinder 7. A rotating cylinder 13 is rotatably fitted inside the screen cylinder 7, and multiple arc-shaped paddles 14 are arrayed and connected to the lower end of the rotating cylinder 13. A worm gear 15 is fitted on the outer side of the rotating cylinder 13. A groove 16 is opened in the side frame 8 and penetrates the screen cylinder 7. A driving component is provided in the groove 16. The driving component is used to drive the rotating cylinder 13 to rotate inside the screen cylinder 7. A slide frame 25 is slidably arranged on the tray 2, and a slide frame 26 is slidably arranged on the slide frame 25. Among them, the vibrating table 1 is an existing vibrating screening equipment. The upper end of the guide hopper cover 4 can be connected to a pipe to transport the carbon black to be screened to the uppermost screen cylinder 7 for step-by-step screening. The sleeve cylinder seat 6 is connected to the discharge hopper 5. Thus, the discharge hopper 5 connected to the lower end of the tray 2 can discharge the carbon black that meets the requirements after multi-stage screening. That is, a conveying mechanism can be arranged below the discharge hopper 5 to convey the carbon black that meets the requirements after screening. The conveying mechanism includes pipes or conveyor belts, etc.

[0022] A collection frame 33 is connected to one side of the sieve cylinder 7, and an opening 34 is provided through the collection frame 33 and the sieve cylinder 7. A slide frame 36 is slidably arranged on the tray 2, and a cleaning box 37 fitted with the collection frame 33 is connected to the slide frame 36. A scraper 43 is slidably arranged inside the collection frame 33. A telescopic component 46 is installed inside the cleaning box 37. A retaining plate 47 that fits with the scraper 43 is connected to the output end of the telescopic component 46. An adjustment component is provided inside the cleaning box 37. The adjustment component is used to adjust the height of the scraper 43 inside the collection frame 33. A linkage component is provided on the slide frame 26. The linkage component is used to drive the scraper 43 to slide up and down inside the collection frame 33 when the slide frame 26 slides up and down. The drive component is used to drive the worm gear 18 to rotate, so as to drive the rotating drum 13 to rotate.

[0023] Multiple screen cylinders 7 are arranged below the feed hopper cover 4, and each screen cylinder 7 is interlocked with the others. The bottom screen cylinder 7 is interlocked with the sleeve base 6. Then, the telescopic component 3 is controlled to retract, and the feed hopper cover 4 is moved down to press the top screen cylinder 7. This allows the multiple screen cylinders 7 to be installed in a tight manner, thus enabling multi-stage screening. The mesh size of the screen 11 on each screen cylinder 7 is different, and the mesh size increases from top to bottom. This allows for multi-stage screening to separate carbon black of different particle sizes, achieving the effect of obtaining carbon black of different particle sizes or screening impurities of different particle sizes.

[0024] The inner wall of the screen cylinder 7 is fitted with an annular platform 12. The lower end of the guide hopper cover 4 extends into the screen cylinder 7 and is fitted inside the screen cylinder 7. The lower end of the guide hopper cover 4 is in contact with the upper end face of the annular platform 12. The lower end face of the screen cylinder 7 is fitted with the next layer of screen cylinder 7 and is in contact with the upper end face of the annular platform 12 inside the next layer of screen cylinder 7.

[0025] The ring platform 12 can effectively support the lower end of the upper screen cylinder 7, preventing the lower end of the upper screen cylinder 7 from sticking and pressing against the upper end of the rotating cylinder 13, thus increasing the resistance when the rotating cylinder 13 rotates.

[0026] Electric guide rails are installed on both sides of the slide 25. There are two slide frames 26, which are slidably installed on the electric guide rails on both sides of the slide 25. The upper end of the side frame 8 is provided with a socket 9, and the lower end of the side frame 8 is also connected with a plug rod 10 that is inserted into the socket 9. This allows the slide frame 26 to move up and down on the slide 25.

[0027] Example 2: like Figures 1-9 As shown, the present invention discloses an impurity screening and treatment device for carbon black production and processing. Compared with Embodiment 1, this embodiment discloses the structure of the driving component.

[0028] The drive assembly includes a worm gear 18, a gear 19, a rotating shaft 20, and a ratchet 22. The two ends of the worm gear 18 are rotatably mounted on the inner walls of both sides of the trough 16 and extend through the trough 16 into the screen cylinder 7, where they mesh with the worm wheel 15. The gear 19 is rotatably mounted on the inner walls of both sides of the trough 16. The rotating shaft 20 is rotatably mounted inside the trough 16. Gears 21 are mounted on both outer sides of the trough 16 and the outer sides of the worm gear 18. The ratchet 22 is mounted on both ends of the rotating shaft 20 and is positioned on one side away from the two gears 21. The gear 19 is positioned between the two gears 21 on the worm gear 18 and the rotating shaft 20 and meshes with the gears 21 on both sides respectively.

[0029] When the ratchet 22 is driven to rotate, it can drive the rotating shaft 20 and the gear 21 set at both ends of the rotating shaft 20 to rotate. Since the gear 21 set at both ends of the rotating shaft 20 meshes with the gear 19, the gear 19 can be driven to rotate. The gear 19 meshes with the gear 21 set at both ends of the worm 18, which can drive the worm 18 to rotate. Through the meshing connection between the worm 18 and the worm wheel 15, the worm wheel 15 and the rotating drum 13 are driven to rotate. This allows the multiple arc-shaped paddles 14 connected to the lower end of the rotating drum 13 to rotate with it. This paddles the impurities or large-diameter carbon black particles on the screen 11 on the screen cylinder 7 that are at the edge due to the vibration of the vibrating table 1, and transfer them to the collection frame 33 through the opening 34. This prevents impurities or large-diameter carbon black particles from accumulating on the screen 11 and affecting its passage, thereby improving the screening efficiency of the screen 11.

[0030] The inner walls on both sides of the groove 16 also have openings 17 through the side frame 8. The two ends of the rotating shaft 20 extend through the openings 17 to the outside of the side frame 8, and ratchet 22 is fitted at the extended ends on the outside. The openings 17 make it convenient for the rotating shaft 20 to extend to the outside of the side frame 8 so that ratchet 22 can be fitted at the extended ends. In this way, ratchet 22 can be easily connected and linked with other structures.

[0031] Example 3: like Figures 1-9 As shown, this invention discloses an impurity screening and treatment device for carbon black production and processing. Compared with Embodiment 2, this embodiment discloses the structure of the adjustment component.

[0032] The adjustment assembly includes a slide 39, a mounting plate 41, a guide rod bracket 42, and a claw 44. The slide 39 is slidably disposed on the outside of the collection frame 33 and extends through the collection frame 33 into it. The mounting plate 41 is connected to the extended end inside the collection frame 33. The guide rod bracket 42 is connected to the mounting plate 41. The scraper 43 is slidably sleeved on the outside of the guide rod bracket 42. A spring 45 sleeved on the outside of the guide rod bracket 42 is connected between the scraper 43 and the end of the guide rod bracket 42. The claw 44 is connected to the scraper 43. The clamping plate 47 and the claw 44 cooperate to clamp.

[0033] When the upper end of the carriage 39 is pressed down, it can drive the scraper 43 in the collection frame 33 to move down and gradually come into contact with the lower inner wall of the collection frame 33. At the same time, it can drive the claw 44 to move down, so that the claw 44 can engage with the card plate 47 connected to the output end of the telescopic component 2 46. By controlling the contraction of the telescopic component 2 46, the claw 44 and the scraper 43 can be pulled to fit against the lower inner wall of the collection frame 33 and slide into the cleaning box 37, thereby transferring the impurities or large-diameter carbon black collected in the collection frame 33 into the cleaning box 37, preventing the impurities or large-diameter carbon black from accumulating in the collection frame 33. At the same time, the bottom of the cleaning box 37 has a discharge port, so the impurities or large-diameter carbon black falling through the discharge port can be transferred by fitting a collection bag at the bottom of the cleaning box 37 or arranging a conveyor mechanism, thereby improving the cleaning effect.

[0034] Both sides of the collection frame 33 are connected to the slide rod frame 38. The two sides of the slide 39 are slidably sleeved on the outside of the slide rod frame 38. A second spring 40 sleeved on the outside of the slide rod frame 38 connects the slide 39 and the collection frame 33. This makes the sliding of the slide 39 more stable. In the absence of external force, the second spring 40 will bounce the slide 39 to a high place.

[0035] Example 4: like Figures 1-9 As shown, the present invention discloses an impurity screening and treatment device for carbon black production and processing. Compared with Embodiment 3, this embodiment discloses the structure of the linkage component.

[0036] The linkage component includes a limiting slot 27, a ratchet 28, a spring 29, and a pressure plate 32. The limiting slot 27 is formed on the slide frame 26. One end of the ratchet 28 is slidably disposed in the limiting slot 27, and the other end passes through the limiting slot 27 to the outside of the slide frame 26. The outer extension end of the ratchet 28 is engaged with the ratchet 22 on its respective side. A spring 29 is connected between one end of the ratchet 28 in the limiting slot 27 and the inner wall of the limiting slot 27. The pressure plate 32 is connected to the slide frame 26 and is arranged in multiple layers. Each layer of the pressure plate 32 cooperates with and abuts against the upper end of the sliding carriage 39 on the corresponding layer of the collection frame 33.

[0037] Multiple telescopic components 3 are arrayed on the upper surface of the pallet 2, and the upper output ends of each telescopic component 3 are connected to a guide hopper cover 4. Guide rails 24 are installed on both radial sides of the pallet 2, and the lower end of the carriage 25 is slidably mounted on the guide rails 24. Guide rail 35 is installed at the rear end of the pallet 2, and the lower end of the carriage 36 is slidably mounted on the guide rail 35. The telescopic components 3 and 46 are both existing equipment, namely existing electric hydraulic cylinders and electric pneumatic cylinders. The cylinder or electric telescopic rod, etc., and the setting of guide rail 1 24 and guide rail 2 35 can adjust the position of slide 1 25 and slide 2 36, so that after the multi-layer screen cylinder 7 is installed, the guide rail 1 24 and guide rail 2 35 drive slide 1 25 and slide 2 36 to move until the cleaning box 37 can be fitted onto the outside of the collection frame 33, and the ratchet 28 can be in contact with and mesh with the ratchet 22. Through the meshing of the ratchet 28 and the ratchet 22, the worm gear 18 rotates, and The worm gear 18 and worm wheel 15 mesh to drive the rotating drum 13 to rotate, causing the multiple arc-shaped paddles 14 arrayed at the lower end of the rotating drum 13 to rotate. This allows impurities or large-diameter carbon black particles on the outer edge of the screen cylinder 7, which have been vibrated and screened by the vibrating table 1, to be collected into the collection frame 33 through the opening 34 by the paddles 14. At the same time, the ratchet 28 slides within the limiting groove 27 of the sliding frame 26, so when the ratchet 28 moves upward, it can drive the ratchet 22 to rotate. When the drum moves downward, the ratchet 28 will compress the spring 29 and retract into the limiting groove 27, not engaging with the ratchet 22. This allows the ratchet 22 to rotate only in one direction, and consequently, the drum 13 can also rotate only in one direction. This drives the arc-shaped paddle 14 to move impurities or large-diameter carbon black particles through the opening 34 into the collection frame 33, preventing impurities or large-diameter carbon black particles from accumulating on the screen 11 of the sieve cylinder 7 and causing blockage, thus improving the throughput and screening efficiency of the sieve cylinder 7.

[0038] The outer side of the side frame 8 is provided with a slot 23. Multiple limiting trapezoidal blocks 31 are connected at equal intervals on the slide 25. Each limiting trapezoidal block 31 is set with a corresponding screen cylinder 7. Both sides of the limiting trapezoidal block 31 are rotatably connected to a rotating plate 30 through a spring hinge. The end of each rotating plate 30 away from the limiting trapezoidal block 31 slides and abuts against the inner wall of its respective slot 23. When the two slides 25 approach each other, the rotating plate 30 connected by the spring hinge will move into the slot 23 and abut against its inner wall. This allows the rotating plate 30 to overcome the elastic force of its own spring hinge and rotate until it abuts against the inner walls of the two sides of the slot 23 and is limited. This can further tighten and stabilize each layer of screen cylinder 7, and prevent gaps from appearing at the clamping points between the layers of screen cylinder 7 due to the vibration of the vibrating table 1, which would cause carbon black powder to escape and pollute the working environment.

[0039] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
