Summary of the invention

The third driving structure is used to rotate the scraper relative to the spiral plate to gradually push the material scraped off by the scraper to the spiral plate. A second slag suction port is provided on the side of the spiral plate facing the scraper.

[0008] The carbon black particles can be transported forward by the rotation of the inner cylinder and the guidance of the spiral plate, reducing the possibility of the carbon black particles being broken by impact and friction. At the same time, the carbon black can be screened to ensure the quality and consistency of the carbon black particles. In addition, after the device has been used for a period of time, the carbon black blocked in the sieve holes and adhered to the inner wall of the inner cylinder can be cleaned through the cooperation of the suction component and the scraper component to ensure the subsequent normal use of the device.

[0009] Preferably, a flexible plate is provided at one end of the scraper facing the inner wall of the inner cylinder, and the flexible plate is gradually inclined along the rotation direction of the inner cylinder toward the inner wall of the inner cylinder. During the process of the scraper moving toward the spiral plate, the flexible plate can scrape the material on the inner wall of the inner cylinder. During the process of the scraper moving away from the spiral plate, or the scraper and the spiral plate remaining relatively fixed, the flexible plate can flip over the material after contacting the material on the inner wall of the inner cylinder to pass over the material.

[0019] Preferably, the driving structure three includes a plurality of elastic blocks, which are arranged inside the inner cylinder at intervals along the circumference of the inner cylinder. During the rotation of the inner cylinder relative to the spiral plate, the scraper can contact the elastic blocks, so that the scraper rotates synchronously with the inner cylinder, so that the scraper and the spiral plate rotate relative to each other.

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 6 As shown, a carbon black conveying device of the present invention includes a frame 1, a material guide plate 11, a cylinder 2, a driving structure 1 and a cleaning mechanism.

[0035] The guide plate 11 is arranged at one end of the cylinder 2 and gradually tilts downward toward the direction close to the cylinder 2, so as to facilitate the addition of the carbon black to be transported into the cylinder 2. The cylinder 2 includes an outer cylinder 21 and an inner cylinder 22. The driving structure 1 is used to drive the inner cylinder 22 to rotate. The circumference of the inner cylinder 22 is densely covered with sieve holes 221 for screening the carbon black. There is a gap between the inner cylinder 22 and the outer cylinder 21 for accommodating fine carbon black powder, and the lower end of the outer cylinder 21 is provided with a discharge port 211 for discharging the fine carbon black powder outward. A plurality of spiral plates 23 are provided inside the inner cylinder 22. The plurality of spiral plates 23 are arranged at intervals along the circumference of the inner cylinder 22 and can rotate synchronously with the inner cylinder 22.

[0036] Specifically, the inner cylinder 22 is driven to rotate through the driving structure 1, and multiple spiral plates 23 are driven to rotate synchronously with the inner cylinder 22, and then the carbon black particles to be transported are added to the inner cylinder 22 along the guide plate 11. Under the guidance of the spiral plate 23, the carbon black particles will gradually move to the other end of the cylinder 2 until they are discharged from the other end of the cylinder 2. During this process, the carbon black fine powder contained in the carbon black particles will enter the space between the inner cylinder 22 and the outer cylinder 21 through the sieve holes 221 on the inner cylinder 22, and be discharged from the discharge port 211. Through the rotation of the inner cylinder 22 and the guidance of the spiral plates 23, the carbon black particles can be transported forward, and in this process, the possibility of the carbon black particles being broken by impact and friction is reduced. At the same time, the carbon black can be screened during the transportation process, and the carbon black fine powder contained therein can be screened out to ensure the quality and consistency of the carbon black particles.

[0037] The cleaning mechanism includes a second driving structure, a suction assembly and a scraper assembly. The second driving structure separates the spiral plate 23 from the inner cylinder 22 so that the two can rotate independently. The interior of the spiral plate 23 is hollow, and a slag suction port 231 is provided on the side facing the inner wall of the inner cylinder 22. The suction assembly can fix the spiral plate 23 and communicate with the interior of the spiral plate 23 in a fixed state. The scraper assembly includes a scraper 24 and a third driving structure. The scraper 24 is spiral and is arranged corresponding to the spiral plate 23. In the initial state, the scraper 24 and the spiral plate 23 remain relatively fixed. The third driving structure is used to rotate the scraper 24 relative to the spiral plate 23 to gradually push the material scraped by the scraper 24 to the spiral plate 23. A second slag suction port 232 is provided on the side of the spiral plate 23 facing the scraper 24.

[0038] After the conveying device has been used for a period of time, the sieve holes 221 may be clogged with carbon black fine powder, and the inner wall of the inner cylinder 22 may be attached with carbon black fine powder, which affects the subsequent screening effect. Therefore, after each completion of the conveying of carbon black particles, the inner cylinder 22 can be cleaned by the cleaning mechanism to clean out the carbon black adhering to the inner wall of the inner cylinder 22 and the carbon black clogged in the sieve holes 221, so as to ensure the subsequent normal use of the inner cylinder 22. Specifically, after the completion of the conveying of carbon black, the spiral plate 23 is separated from the inner cylinder 22 by the driving structure 2, so that the two can rotate independently, and the spiral plate 23 is fixed by the suction component, so that the suction component is connected to the inside of the spiral plate 23, and then the inner cylinder 22 is driven by the driving structure 1. The inner cylinder 22 rotates relative to the spiral plate 23, and the suction component sucks air at this time, so that the carbon black blocked in the sieve hole 221 can be cleaned out through the suction port 231 provided on the spiral plate 23. In the process of the inner cylinder 22 rotating relative to the spiral plate 23, the scraper 24 and the spiral plate 23 can be made to rotate relative to each other through the driving structure 3, so that the carbon black adhering to the inner wall of the inner cylinder 22 can be scraped off and pushed to the spiral plate 23 through the movement of the scraper 24, and then the scraped carbon black is cleaned away through the suction port 232 provided on the spiral plate 23, and the carbon black cleaned out from the sieve hole 221 and the carbon black scraped off from the inner wall of the inner cylinder 22 will be discharged to the outside of the cylinder body 2 for collection by the suction component.

[0039] It should be noted that a flexible plate 241 is provided at one end of the scraper 24 facing the inner wall of the inner cylinder 22, and the flexible plate 241 gradually tilts along the rotation direction of the inner cylinder 22 toward the inner wall of the inner cylinder 22. In the process of the scraper 24 moving toward the direction close to the spiral plate 23, the flexible plate 241 can scrape the material on the inner wall of the inner cylinder 22. In the process of the scraper 24 moving in the direction away from the spiral plate 23, or the scraper 24 and the spiral plate 23 remain relatively fixed, the flexible plate 241 can flip over the material on the inner wall of the inner cylinder 22 after contacting the material, so that in the process of the scraper 24 rotating relative to the spiral plate 23, only when the scraper 24 moves in the direction close to the spiral plate 23, the flexible plate 241 under the scraper 24 will scrape the carbon black adhered to the inner wall of the inner cylinder 22, so that the scraped material can be accumulated on the side of the scraper 24 close to the spiral plate 23, which is convenient for the suction component to clean.

[0040] In some embodiments, a fixed plate 25 is connected to one side of the spiral plate 23 facing the scraper 24 , and a space is provided between the fixed plate 25 and the inner wall of the inner cylinder 22 for the scraper 24 to reciprocate.

[0041] Specifically, Figures 1 to 4As shown, when the scraper 24 is driven by the driving structure three to move in the direction close to the spiral plate 23, the scraper 24 will move in the space formed between the fixed plate 25 and the inner wall of the inner cylinder 22, so that when the scraper 24 pushes the scraped material to the spiral plate 23, the fixed plate 25 can block the material, so that the scraped material is always between the scraper 24 and the spiral plate 23, to ensure that the material can be smoothly sucked away from the slag suction port 2 232, to avoid that during the movement of the scraper 24, some materials pass over the scraper 24 and move to the side of the scraper 24 away from the spiral plate 23, affecting the subsequent cleaning of this part of the material by the suction component.

[0042] In some embodiments, the driving structure 1 includes a motor 12 disposed on the frame 1, and a friction wheel 13 connected to the output end of the motor 12. The friction wheel 13 is rotatably disposed on the frame 1 and frictionally drives with the inner cylinder 22. Specifically, Figure 1 Hezhi Figure 5 As shown, when the starter motor 12 drives the friction wheel 13 to rotate, the inner cylinder 22 can be driven to rotate through the friction transmission between the friction wheel 13 and the inner cylinder 22 .

[0043] In some embodiments, mounting rings 26 are connected to both ends of the spiral plate 23. The mounting ring 26 away from the discharge port 211 is in contact with the inner cylinder 22, and the contact surfaces of the two are rough, so that the mounting ring 26 can rotate synchronously with the inner cylinder 22 under friction transmission.

[0044] Specifically, Figures 4 to 6 As shown, when the rough surface on the mounting ring 26 contacts the rough surface on the inner cylinder 22, the inner cylinder 22 is driven to rotate through the driving structure 1, and the mounting ring 26 can be driven to rotate synchronously with the inner cylinder 22 through the friction transmission between the mounting ring 26 and the inner cylinder 22, and the spiral plate 23 can be driven to rotate synchronously with the inner cylinder 22.

[0045] In some embodiments, the suction assembly includes a suction piece 31 arranged on the frame 1, a fixing rod 212 is provided on the outer cylinder 21, the suction piece 31 slides with the fixing rod 212 along the length direction of the outer cylinder 21, and the spiral plate 23 has a through opening 233 on the side facing the suction piece 31, and the suction port of the suction piece 31 can be magnetically matched with the through opening 233 on the spiral plate 23 to make the two communicate with each other.

[0046] Specifically, Figures 2 to 6As shown, when the inner cylinder 22 needs to be cleaned, the suction port of the suction member 31 is magnetically matched with the through port 233 on the spiral plate 23, so that the suction member 31 is communicated with the inside of the spiral plate 23. At this time, the suction member 31 is started to suck air, and the carbon black fine powder blocked in the sieve hole 221 can be sucked out through the slag suction port 1 231 provided on the spiral plate 23. At the same time, the carbon black scraped off by the scraper 24 can be sucked away through the slag suction port 232 provided on the spiral plate 23, and the inner cylinder 22 is gradually cleaned by the rotation of the inner cylinder 22.

[0047] In some embodiments, driving structure 2 includes an electric push rod 32 disposed on a fixed rod 212, and an output end of the electric push rod 32 is connected to the suction member 31, for driving the suction member 31 to move along the length direction of the cylinder 2, and an electric push rod 2 33 is provided at one end of the inner cylinder 22 away from the suction member 31, and an output end of the electric push rod 23 faces the mounting ring 26 close to the discharge port 211, for pushing the mounting ring 26 and the spiral plate 23 to move along the length direction of the cylinder 2.

[0048] Specifically, Figures 1 to 6 As shown, when the inner cylinder 22 and the spiral plate 23 need to rotate independently, the electric push rod 32 is started to extend the output end of the electric push rod 32 to drive the suction member 31 to move in the direction close to the cylinder body 2, so that the suction port of the suction member 31 is magnetically matched with the through hole 233 on the spiral plate 23. At this time, the output end of the electric push rod 32 continues to extend and drives the suction member 31 and the spiral plate 23 to move along the length direction of the cylinder body 2. With the movement of the spiral plate 23, the mounting ring 26 is driven to move synchronously, so that the contact surface of the mounting ring 26 with the inner cylinder 22 is separated, that is, the mounting ring 26 is released from the inner cylinder 22. The friction transmission between the inner cylinder 22, when the inner cylinder 22 is driven to rotate by the driving structure 1, the spiral plate 23 remains stationary under the magnetic attraction of the suction member 31, so that the inner cylinder 22 and the spiral plate 23 rotate relative to each other. After the cleaning of the inner cylinder 22 is completed, the electric push rod 2 33 is started to extend the output end of the electric push rod 2 33 to push the mounting ring 26 and the spiral plate 23 to move and reset, so that the surfaces of the mounting ring 26 and the inner cylinder 22 that can contact each other are contacted again, that is, the friction transmission between the inner cylinder 22 and the mounting ring 26 is restored, and the spiral plate 23 can rotate synchronously with the inner cylinder 22.

[0049] In some embodiments, the driving structure three includes a plurality of elastic blocks 27, and the plurality of elastic blocks 27 are arranged inside the inner cylinder 22 at intervals along the circumference of the inner cylinder 22. During the rotation of the inner cylinder 22 relative to the spiral plate 23, the scraper 24 can contact the elastic blocks 27, so that the scraper 24 rotates synchronously with the inner cylinder 22, so that the scraper 24 and the spiral plate 23 rotate relative to each other. A fixed block 261 is provided on the mounting ring 26, and the fixed block 261 is arranged on the side of the scraper 24 away from the spiral plate 23, and an elastic member 28 is connected between the fixed block 261 and the scraper 24, and the force of the elastic block 27 is greater than the force of the elastic member 28.

[0050] Specifically, Figures 1 to 6 As shown, the spiral plate 23 is fixed relative to the frame 1 through the magnetic attraction between the air suction member 31 and the spiral plate 23, and the scraper 24 is relatively fixed to the spiral plate 23 under the action of the elastic member 28. At this time, the inner cylinder 22 is driven to rotate relative to the spiral plate 23 through the driving structure 1, which drives the multiple elastic blocks 27 arranged in the inner cylinder 22 to move relative to the spiral plate 23. In this process, the multiple elastic blocks 27 will contact with the scraper 24 in turn. When the elastic block 27 contacts with the scraper 24, As the inner cylinder 22 continues to rotate, the elastic block 27 will push the scraper 24 to rotate synchronously with the inner cylinder 22, that is, the scraper 24 moves toward the direction close to the spiral plate 23, and the elastic member 28 is stretched to accumulate force until the scraper 24 contacts the spiral plate 23. At this time, as the inner cylinder 22 continues to rotate, the scraper 24 remains stationary until the elastic block 27 contracts and passes over the scraper 24 and the spiral plate 23. At this time, the scraper 24 will move away from the spiral plate 23 under the action of the elastic member 28 to reset.

[0051] In some embodiments, the frame 1 has a first support leg 14 and a second support leg 15, and the lengths of the first support leg 14 and the second support leg 15 can be adjusted to adjust the inclination angle of the cylinder 2, thereby avoiding the situation where the carbon black particles slip and cannot be completely screened, so as to ensure the screening effect of the carbon black particles.

[0052] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
