Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon black production technology, and in particular to a carbon black production pulverizer. Background Technology
[0002] Current carbon black pulverizing equipment employs multiple pulverizing methods to ensure particle size during carbon black pulverization. This method requires the simultaneous operation of screening devices and multiple pulverizing mechanisms, resulting in a complex structure, high power consumption, and the inability to control the discharge volume of pulverized carbon black according to production needs.
[0003] Therefore, how to solve the problem of complex structure of multiple crushing mechanisms and adjust the carbon black output as needed during production is a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a carbon black production pulverizer that can adjust the particle size of carbon black pulverizer as needed.
[0005] To achieve the above objectives, this utility model provides a carbon black production pulverizer, including a crushing box. A feed inlet is provided at the top of the crushing box. A first crushing roller and a second crushing roller are rotatably arranged parallel to each other inside the crushing box. The first and second crushing rollers are staggered, with the first crushing roller positioned above the second crushing roller. One end of each of the first and second crushing rollers extends out of the crushing box and is respectively connected to a first transmission gear and a second transmission gear. The first and second transmission gears mesh with each other. The other end of the second crushing roller is connected to a drive connection mechanism, which is connected to... The crushing box is equipped with a drive motor, a vertically arranged feeding extrusion plate on one side of the second crushing roller, a slide rail on the bottom surface of the crushing box, the slide rail being perpendicular to the first crushing roller, the feeding extrusion plate being horizontally slidably arranged on the slide rail, a first arc-shaped extrusion block being formed at the lower end of the feeding extrusion plate near the second crushing roller, the first arc-shaped extrusion block having an inwardly concave arc surface, a push-pull device for driving the feeding extrusion plate to move horizontally on the side wall of the crushing box, a discharge port being opened at the bottom of the crushing box, and an inclined baffle plate being provided at the feed port for conveying materials to the side near the first crushing roller.
[0006] The working process and principle of the above structure are as follows:
[0007] During the crushing operation, carbon black raw material enters the crushing chamber, falls through the baffle plate onto the right side of the first crushing roller, and the drive connecting mechanism drives the second crushing roller to rotate counterclockwise. The second transmission gear transmits power to the first crushing roller through the first transmission gear, and the first crushing roller rotates clockwise synchronously with the second crushing roller. The carbon black raw material first contacts the first crushing roller, which forms a crushing and extrusion space with the inner wall of the crushing chamber, crushing all the carbon black raw material passing through. After the first extrusion, the material falls onto the first and second crushing rollers for secondary refinement and crushing. The crushed carbon black material falls onto the feeding extrusion plate and the first arc-shaped extrusion block, and slides down the inclined concave arc surface into the discharge port for discharge. When it is necessary to adjust the discharge volume, the feeding extrusion plate can be moved horizontally along the slide rail by the push-pull device, and the gaps between the feeding extrusion plate and the first arc-shaped extrusion block and the second crushing roller can be adjusted respectively. In this way, the gap between the first arc-shaped extrusion block and the discharge port can be adjusted, thereby realizing the adjustment of the carbon black discharge volume. Furthermore, the counterclockwise rotation of the second crushing roller can reduce the thickness of the material during discharge and prevent the risk of material blockage. It can be adjusted in real time according to actual usage requirements.
[0008] Furthermore, the push-pull device includes a rotating seat, a threaded seat, and a pushing screw. The threaded seat is fixed to the side wall of the crushing box and has a threaded hole. The pushing screw is threaded into the threaded hole. The rotating seat is located on the vertical outer side wall of the feeding extrusion plate and has a rotating cavity formed inside. A rotating hole is formed at one end of the rotating seat near the pushing screw. One end of the pushing screw extends through the rotating hole into the rotating cavity, and a limiting rotating block is connected to one end of the pushing screw located in the rotating cavity. A driving device is connected to the other end of the pushing screw.
[0009] When adjusting the position of the feeding extrusion plate, the drive device drives the push screw to rotate. The threaded seat provides support force and displacement step thrust for the push screw. Through the cooperation of the limiting rotating block and the rotating seat, the displacement of the feeding extrusion plate is driven. The rotating cavity is used to accommodate the limiting rotating block. The push screw is used in a progressive manner, which is mainly to facilitate precise control of the displacement distance of the feeding extrusion plate. This allows for precise adjustment of the distance between the first arc-shaped extrusion block and the second crushing roller, ensuring that the adjusted carbon black output is relatively accurate.
[0010] Furthermore, the driving device is a rotary handle.
[0011] The rotating handle allows for easy manual adjustment to rotate the push screw.
[0012] Furthermore, the driving device is a first drive motor.
[0013] The first drive motor automatically drives the top screw to rotate, enabling automated control and adjustment with higher control precision.
[0014] Furthermore, the upper width of the crushing box is smaller than the lower width.
[0015] This configuration facilitates the coordinated positioning of the first and second crushing rollers, allowing for a narrower crushing space between the first crushing roller and the inner wall of the crushing chamber. It also facilitates the formation of a storage space at the concave surface of the first arc-shaped extrusion block, resulting in more stable material feeding after crushing.
[0016] Furthermore, a second arc-shaped extrusion block is provided on the bottom side of the crushing box away from the first arc-shaped extrusion block, and the discharge port is located between the first arc-shaped extrusion block and the second arc-shaped extrusion block.
[0017] The first and second arc-shaped extrusion blocks work together with the second crushing roller to form a second crushing process.
[0018] Furthermore, the distance between the upper and lower parts of the first arc-shaped extrusion block and the second crushing roller gradually decreases, as does the distance between the upper and lower parts of the second arc-shaped extrusion block and the second crushing roller.
[0019] This setup ensures that the degree of crushing from top to bottom gradually increases, thereby ensuring the size of the crushed particles.
[0020] Furthermore, both the first crushing roller and the second crushing roller are provided with toothed patterns on their surfaces, and the first crushing roller and the second crushing roller mesh with each other.
[0021] The toothed design ensures meshing between the first and second crushing rollers, guaranteeing the transmission effect between them. At the same time, small particles of raw material are stored between the teeth, while large particles are crushed by compression.
[0022] Furthermore, a feed hopper is provided on the outside of the feed inlet, and a vertically arranged material distribution baffle is provided in the center of the feed hopper. The upper two ends of the material distribution baffle are respectively hinged to the inner wall of the feed hopper. One of the hinge shafts of the material distribution baffle extends out of the feed hopper and is connected to a first hinge rod. The axis of the hinge shaft of the material distribution baffle is perpendicular to the axis of the first crushing roller. A second drive motor is provided on one side of the feed hopper. A rotating disk is provided on the output shaft of the second drive motor. A second hinge rod is hinged on the rotating disk. The other end of the second hinge rod is hinged to the first hinge rod.
[0023] The second drive motor drives the rotary disk to rotate, which in turn drives the first hinge rod to swing through the second hinge rod, thereby causing the material distribution baffle to swing in the feed hopper, so as to evenly distribute the carbon black raw material on the first crushing roller and ensure more uniform feeding.
[0024] Furthermore, a plurality of compression crushing blocks are provided on the side wall of the crushing box near the first crushing roller, and the compression crushing blocks are located at positions corresponding to the first crushing roller.
[0025] The crushed blocks are crushed in conjunction with the first crushing roller to ensure the strength and force of the crushing.
[0026] The carbon black production pulverizer of this invention operates as follows: During crushing, the carbon black raw material enters the crushing chamber, falls through the baffle plate onto the right side of the first crushing roller, and the drive connecting mechanism drives the second crushing roller to rotate counterclockwise. The second transmission gear transmits power to the first crushing roller through the first transmission gear, and the first crushing roller rotates clockwise synchronously with the second crushing roller. The carbon black raw material first contacts the first crushing roller, which rotates clockwise, forming a crushing and extrusion space with the inner wall of the crushing chamber. This space completely crushes the passing carbon black raw material. The material after the first extrusion falls onto the first and second crushing rollers for further crushing. The carbon black material undergoes secondary refining and crushing. After secondary crushing, it falls onto the feeding extrusion plate and the first arc-shaped block, and slides down the inclined concave arc surface into the discharge port for discharge. When it is necessary to adjust the discharge volume, the feeding extrusion plate can be moved horizontally along the slide rail by the push-pull device. The gaps between the feeding extrusion plate and the first arc-shaped extrusion block and the second crushing roller can be adjusted respectively, thereby adjusting the gap between the first arc-shaped extrusion block and the discharge port, thus realizing the adjustment of the carbon black discharge volume. In addition, the counterclockwise rotation of the second crushing roller can reduce the thickness of the material during discharge and prevent the risk of material blockage. It can be adjusted in real time according to actual use needs.

[0035] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0036] The core of this utility model is to provide a carbon black production pulverizer to improve the effective load capacity of the carbon black production pulverizer.
[0037] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0038] Please refer to Figures 1 to 5This utility model discloses a carbon black production pulverizer, including a crushing box 1 with a feed inlet 20 at the top. The crushing box 1 has an L-shaped structure. A first crushing roller 2 and a second crushing roller 3 are rotatably arranged parallel to each other inside the crushing box 1, staggered. The first crushing roller 2 is located above the second crushing roller 3. One end of each of the first and second crushing rollers 2 and 3 extends out of the crushing box 1 and is respectively connected to a first transmission gear 4 and a second transmission gear 5, which mesh with each other. The other end of the second crushing roller 3 is connected to a drive connection mechanism 6, which is connected to a drive motor (not shown in the figure). The drive motor is a geared motor. The figure shows a vertically arranged... The material feeding extrusion plate 7 is positioned with the same height as the inside of the crushing box 1. The width of the material feeding extrusion plate 7 is matched with the width of the crushing box 1. A slide rail 8 is provided on the bottom surface of the crushing box 1. The longitudinal section of the slide rail 8 is a T-shaped structure, which makes the slide rail more stable. The slide rail 8 is set perpendicular to the axis of the first crushing roller 2. The material feeding extrusion plate 7 is horizontally slidably set on the slide rail 8. A first arc-shaped extrusion block 9 is formed at the lower end of the material feeding extrusion plate 7 near the second crushing roller 3. The first arc-shaped extrusion block 9 has an inwardly concave arc surface. A push-pull device is provided on the side wall of the crushing box 1 to drive the material feeding extrusion plate 7 to move horizontally. A discharge port 10 is opened at the bottom of the crushing box 1. An inclined baffle plate 28 is provided at the inlet 20 to transport the material to the right side of the first crushing roller 2.
[0039] The working process and principle of the above structure are as follows:
[0040] During the crushing operation, carbon black raw material enters the crushing chamber 1, falls through the baffle 28 onto the right side of the first crushing roller 2, and the drive connecting mechanism 6 drives the second crushing roller 3 to rotate counterclockwise. The second transmission gear 5 transmits power to the first crushing roller 2 through the first transmission gear 4. The first crushing roller 2 rotates clockwise synchronously with the second crushing roller 3. The carbon black raw material first contacts the first crushing roller 2, and the first crushing roller 2 forms a crushing and extrusion space with the inner wall of the crushing chamber 1, crushing all the carbon black raw material. Since the carbon black raw material is not very hard, it is possible to achieve a crushing fit between the first crushing roller 2 and the inner wall of the crushing chamber 1. After the first crushing, the material falls onto the first crushing roller 2 and the second crushing roller 3. The carbon black material undergoes secondary crushing and extrusion at crushing roller 3. After secondary crushing, the carbon black material falls onto the feeding extrusion plate 7 and the first arc-shaped extrusion block 9, and slides down the inclined concave arc surface into the discharge port 10 for discharge. When it is necessary to adjust the discharge volume, the feeding extrusion plate 7 can be moved horizontally along the slide rail 8 by the push-pull device. The gaps between the feeding extrusion plate 7 and the first arc-shaped extrusion block 9 and the second crushing roller 3 can be adjusted respectively, thereby adjusting the gap between the first arc-shaped extrusion block 9 and the discharge port 10, thus realizing the adjustment of the carbon black discharge volume. In addition, the counterclockwise rotation of the second crushing roller 3 can reduce the thickness of the material during discharge and prevent the risk of material blockage. It can be adjusted in real time according to actual usage requirements.
[0041] In another embodiment of this utility model, such as Figure 2 and Figure 5 As shown, the push-pull device includes a rotating seat 11, a threaded seat 12, and a push screw 13. The threaded seat 12 is fixed on the side wall of the crushing box 1, and a threaded hole 14 is provided on the threaded seat 12. The push screw 13 is threadedly engaged with the threaded hole 14. The rotating seat 11 is set on the vertical outer side wall of the feeding extrusion plate 7. A rotating cavity 16 is formed inside the rotating seat 11. A rotating hole 15 is provided at one end of the rotating seat 11 near the push screw 13. One end of the push screw 13 extends through the rotating hole 15 into the rotating cavity 16, and one end of the push screw 13 located in the rotating cavity 16 is connected to a limiting rotating block 17. The limiting rotating block 17 has a hemispherical structure, and the other end of the push screw 13 is connected to a driving device.
[0042] When adjusting the position of the feeding extrusion plate 7, the drive device drives the push screw 13 to rotate. The threaded seat 12 provides support force and displacement stepping thrust for the push screw 13. Through the cooperation of the limiting rotating block 17 and the rotating seat 11, the feeding extrusion plate 7 is displaced. The rotating cavity 16 is used to accommodate the limiting rotating block 17. The push screw 13 is used in a progressive manner, which is mainly to facilitate precise control of the displacement distance of the feeding extrusion plate 7. This allows for precise adjustment of the distance between the first arc-shaped extrusion block 9 and the second crushing roller 3, ensuring that the adjusted carbon black output is relatively accurate.
[0043] In another embodiment of this utility model, such as Figures 1-5 As shown, the driving device is a rotary handle 18.
[0044] The rotating handle 18 allows for easy manual adjustment to rotate the push screw 13.
[0045] In another embodiment of this invention, the driving device is a first drive motor, which is not shown in the figures.

[0047] In another embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the upper width of the crushing box 1 is smaller than the lower width.
[0048] This configuration facilitates the coordinated positional structure of the first crushing roller 2 and the second crushing roller 3, which are staggered. It also allows for a narrower crushing space between the first crushing roller 2 and the inner wall of the crushing box 1, and facilitates the formation of a certain material storage space at the concave arc surface of the first arc-shaped extrusion block 9, making the feeding of crushed material more stable.
[0049] In another embodiment of this utility model, such as Figure 2 As shown, a second arc-shaped extrusion block 19 is provided on the bottom side of the crushing box 1 away from the first arc-shaped extrusion block 9, and the discharge port 10 is located between the first arc-shaped extrusion block 9 and the second arc-shaped extrusion block 19.

[0052] This setup ensures that the degree of crushing from top to bottom gradually increases, thereby ensuring the size of the crushed particles.
[0053] In another embodiment of this utility model, such as Figures 2-4 As shown, the surfaces of the first crushing roller 2 and the second crushing roller 3 are both provided with teeth, which are inclined teeth, and the first crushing roller 2 and the second crushing roller 3 mesh with each other.
[0054] The toothed pattern ensures meshing between the first crushing roller 2 and the second crushing roller 3, guaranteeing the transmission effect between them. At the same time, small particles of raw material are stored between the teeth, while large particles of raw material are crushed by compression.
[0055] In another embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a feed hopper 21 is provided on the outside of the feed inlet 20. The feed inlet 20 is located directly above the first crushing roller 2. A vertically arranged material distribution baffle 22 is provided in the center of the feed hopper 21. The upper two ends of the material distribution baffle 22 are respectively hinged to the inner wall of the feed hopper 21. One of the hinge shafts of the material distribution baffle 22 extends out of the feed hopper 21 and is connected to a first hinge rod 23. The axis of the hinge shaft of the material distribution baffle 22 is perpendicular to the axis of the first crushing roller 2. A second drive motor 25 is provided on one side of the feed hopper 21. A rotating disk 26 is provided on the output shaft of the second drive motor 25. A second hinge rod 24 is hinged on the rotating disk 26. The other end of the second hinge rod 24 is hinged to the first hinge rod 23.
[0056] The second drive motor 25 drives the rotary disk to rotate, and the second hinge rod 24 drives the first hinge rod 23 to swing, which in turn drives the material distribution baffle 22 to swing in the feed hopper 21, so as to evenly distribute the carbon black raw material on the first crushing roller 2 and ensure more uniform feeding.
[0057] In another embodiment of this utility model, such as Figure 2 As shown, a number of compression crushing blocks 27 are provided on the side wall of the crushing box 1 near the first crushing roller 2. The compression crushing blocks 27 are protruding structures and are located at positions corresponding to the first crushing roller 2.
