Description

Technical Field

[0001] The present invention relates to the technical field of carbon black processing equipment, in particular to an ultrafine pulverizer for producing high value-added carbon black. Background Art

[0002] Carbon black, also known as carbon black, is a form of amorphous carbon. It is a light, loose, and extremely fine black powder, which can be figuratively understood as pot ash. It is a product of incomplete combustion or thermal decomposition of carbon-containing substances such as coal, natural gas, heavy oil, and fuel oil in air-deficient conditions.

[0003] During the production of carbon black, the carbon black raw materials need to be crushed into different mesh sizes according to processing requirements. Among them, ring roller mills are usually used in the market to crush carbon black. However, when existing ring roller mills are used to process carbon black, on the one hand, the rotor inside the ring roller mill can only be squeezed and ground with the grinding plate on the outside, and the grinding area is limited, which affects the working efficiency of the equipment; on the other hand, the mesh size that the traditional ring roller mill rotor can grind is designed at the factory and cannot be changed according to subsequent needs, resulting in the poor adjustability and adaptability of most ring roller mills. Summary of the Invention

[0004] The present invention discloses an ultrafine pulverizer for producing high-value-added carbon black, aiming to solve the technical problem that the functionality and working efficiency of equipment for pulverizing carbon black in the existing market need to be improved.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An ultrafine pulverizer for producing high-value-added carbon black comprises a machine body, a feed pipe connected to a side of the machine body, a pulverizing mechanism for grinding carbon black disposed at a lower portion of the machine body, the pulverizing mechanism comprising a base fixedly mounted at a lower portion of the machine body, an electrically controlled turntable rotatably mounted on the top of the base, and a frame fixedly mounted on the top of the electrically controlled turntable;

[0007] The outer side of the pulverizing mechanism is provided with an adjustment mechanism for adjusting the pulverizing mesh size. The pulverizing mechanism and the adjustment mechanism are in press contact. The adjustment mechanism includes an outer grinding ring slidably distributed inside the body. The outer grinding ring is in contact with the inner wall of the body. An inner grinding member is slidably distributed inside the frame.

[0008] A filtering mechanism for screening carbon black dust is provided above the interior of the machine body, and the filtering mechanism comprises an outer sieve cylinder fixedly mounted above the interior of the machine body, and an inner sieve cylinder is slidably sleeved inside the outer sieve cylinder;

[0009] A material guiding mechanism is provided on the side of the machine body;

[0010] The pulverizing mechanism cooperates with the regulating mechanism to process carbon black of different mesh sizes according to demand. At the same time, the filtering mechanism operates synchronously to perform synchronous adjustment and screening according to the mesh size of the carbon black dust.

[0011] By arranging a crushing mechanism inside the machine body, the multiple grinding modes of the crushing mechanism can improve the traditional work efficiency. At the same time, in conjunction with the operation of the adjustment mechanism, carbon black of different mesh sizes can be processed according to demand, thereby improving the functionality of traditional equipment. The filtering mechanism operates synchronously, and synchronously adjusts and screens according to the mesh size of the carbon black dust, thereby further improving the functionality of the traditional equipment.

[0012] In a preferred solution, the pulverizing mechanism further includes a plurality of groups of rotors evenly distributed and rotatably mounted inside the frame.

[0013] By setting the traditional single-sided rotor grinding structure to a double-layer rotor grinding structure, the electric-controlled turntable drives the frame to rotate, causing the rotor to revolve. At the same time, both sides of the rotor can be squeezed and contacted with the adjustment mechanism, thereby utilizing the middle area of the traditional ring roller mill and using both sides of the rotor to grind the carbon black at the same time, thereby greatly improving the crushing efficiency and discharge speed of traditional equipment.

[0014] In a preferred embodiment, the adjustment mechanism further includes several groups of arc surface portions provided on the close surfaces of the outer grinding ring and the inner grinding member, the arc surface portions are arc surface structures inclined outward from bottom to top, and both sides of each group of the rotors are distributed corresponding to the arc surface portions, and two electric push rods are symmetrically installed on the top of the body, and the output ends of the electric push rods vertically penetrate into the interior of the body and are fixedly connected to the top of the inner grinding member.

[0015] By arranging an outer grinding ring and an inner grinding piece with several groups of arc surfaces to clamp the two sides of the rotor, the carbon black is crushed from multiple directions by utilizing the synchronous contact between the two sides of the rotor and the outer grinding ring and the inner grinding piece as the rotor revolves, thereby improving work efficiency. In addition, as the outer grinding ring and the inner grinding piece move vertically, the distance between the rotor and the arc surface is changed by changing the relative position of the two, thereby adjusting the mesh size of the carbon black processed by the equipment according to demand, thereby greatly improving the functionality of the equipment.

[0016] In a preferred solution, the filtering mechanism also includes a bottom plate rotatably mounted on the bottom of the inner sieve cylinder, the two ends of the bottom plate are respectively fixedly socketed with the output ends of the two electric push rods, a threaded groove is provided on the outer side of the bottom of the bottom plate, the inner sieve cylinder is threadedly connected to the inner wall of the outer sieve cylinder through the threaded groove, and the top of the outer sieve cylinder is fixedly connected to a cover cylinder, and the cover cylinder passes through the top of the machine body.

[0017] By setting the filtering structure of the traditional equipment to a double-layer structure consisting of an outer sieve drum and an inner sieve drum, and using an electric push rod to pull the outer grinding ring and the inner grinding part to move vertically, the inner sieve drum will be driven to move at the same time. The moving inner sieve drum will rotate due to the drive of the thread groove, thereby being misaligned with the outer sieve drum, and the mesh size of the carbon black dust that can flow through will be changed in turn, thereby adapting to the operation of the adjustment mechanism and further improving the functionality of this equipment.

[0018] In a preferred solution, a plurality of groups of scrapers are fixed to the opposite surfaces of the outer grinding ring and the inner grinding member, and each of the scrapers is distributed on the top of a curved surface.

[0019] By arranging several groups of scrapers on the sides of the outer grinding ring and the inner grinding piece, the scrapers in contact with the rotor can clean the surface of the rotor as the outer grinding ring and the inner grinding piece move and the rotor rotates, thereby further improving the functionality of the equipment.

[0020] In a preferred embodiment, the material guiding mechanism includes a plurality of air inlets evenly opened on the outside of the bottom of the body, a material guiding cavity is vertically opened on the inner wall of the body, the bottom end of the material guiding cavity is connected to the air inlet, the top end of the material guiding cavity passes through the inner wall of the body and is distributed corresponding to the filtering mechanism in the horizontal direction, and a plurality of material guiding ports are evenly opened at the connection between the electric control turntable and the frame, and the material guiding ports and the material guiding cavity are connected.

[0021] By providing an air inlet, a material guide cavity and a material guide port, the operation of the filtering mechanism is utilized to drive the air path inside the equipment to change, thereby ensuring the integrity of the operation of the equipment.

[0022] In a preferred embodiment, a plurality of inclined material guide tubes are evenly arranged above the inner wall of the machine body, the inclined material guide tubes are connected to the top of the material guide cavity, the inclined material guide tubes and the outer screen cylinder are correspondingly distributed in the horizontal direction, and the inclination direction of the inclined material guide tubes is opposite to the direction of the filter disc of the outer screen cylinder.

[0023] By arranging a material guide inclined pipe at the top of the material guide cavity for connection, the flow direction of the air path flowing from the inside of the material guide cavity is changed. At the same time, the inclination direction of the material guide inclined pipe is opposite to the direction of the filter disc of the outer sieve drum, so that the inclined air path can directly blow the surface of the outer sieve drum, thereby improving the filtration efficiency of the filtration mechanism.

[0024] From the above, it can be seen that the ultrafine grinder for producing high value-added carbon black provided by the present invention has the following technical effects.

[0025] Firstly, by changing the traditional single-sided rotor grinding structure to a double-sided rotor grinding structure, the rotor is driven to revolve along with the electric-controlled turntable, and both sides of the rotor can be squeezed and contacted with the adjustment mechanism, thereby utilizing the middle area of the traditional ring roller mill and using both sides of the rotor to grind the carbon black at the same time, thereby greatly improving the crushing efficiency and discharge speed of the traditional equipment.

[0026] Secondly, an outer grinding ring with several groups of arc-shaped surfaces and an inner grinding piece are provided to clamp the two sides of the rotor. As the rotor revolves, the outer grinding ring and the inner grinding piece move vertically at the same time. The relative position of the rotor and the arc-shaped surface is changed to change the distance between the two. The mesh size of the carbon black processed by the equipment can be adjusted according to demand, which greatly improves the functionality of traditional crushing equipment.

[0027] Thirdly, by arranging several groups of scrapers on the sides of the outer grinding ring and the inner grinding piece, the scrapers in contact with the rotor can clean the surface of the rotor as the outer grinding ring and the inner grinding piece move and the rotor rotates, thereby further improving the functionality of the equipment.

[0028] Fourthly: by setting the filtering structure of the traditional equipment to a double-layer structure consisting of an outer sieve drum and an inner sieve drum, the outer grinding ring and the inner grinding part are pulled vertically by an electric push rod, which will also drive the inner sieve drum to move. The moving inner sieve drum is driven by the thread groove to rotate, thereby being misaligned with the outer sieve drum, and changing the mesh size of the carbon black dust that can flow in turn, thereby adapting to the operation of the adjustment mechanism. When the mesh size of the processed carbon black is changed, the mesh size of the filtered carbon black can also be changed, thereby further improving the functionality of this equipment.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] The invention discloses an ultrafine grinder for producing high-value-added carbon black, which is mainly used for ultrafine grinding of carbon black.

[0042] Reference Figures 1 to 10 An ultrafine pulverizer for producing high-value-added carbon black includes a body 1, a feed pipe 2 connected to the side of the body 1, a pulverizing mechanism 3 for grinding carbon black is provided at the lower part of the body 1, and the pulverizing mechanism 3 includes a base 301 fixedly mounted at the lower part of the body 1, an electric-controlled turntable 302 is rotatably mounted on the top of the base 301, and a frame 303 is fixedly mounted on the top of the electric-controlled turntable 302;

[0043] An adjusting mechanism 4 for adjusting the size of the crushed mesh is provided on the outside of the crushing mechanism 3. The crushing mechanism 3 and the adjusting mechanism 4 are in press contact. The adjusting mechanism 4 includes an outer grinding ring 401 that is slidably distributed inside the body 1. The outer grinding ring 401 is in contact with the inner wall of the body 1. An inner grinding member 402 is slidably distributed inside the frame 303.

[0044] A filter mechanism 5 for screening carbon black dust is provided above the interior of the body 1. The filter mechanism 5 comprises an outer sieve drum 501 fixedly mounted above the interior of the body 1. An inner sieve drum 502 is slidably sleeved inside the outer sieve drum 501.

[0045] A material guiding mechanism 6 is provided on the side of the machine body 1;

[0046] By cooperating with the operation of the pulverizing mechanism 3 and the regulating mechanism 4, carbon black of different mesh sizes can be processed according to demand. At the same time, the filtering mechanism 5 operates synchronously to adjust and screen the carbon black dust according to the mesh size.

[0047] In this embodiment: before use, the top of the filtering mechanism 5 is docked with the external exhaust device, and the feeding pipe 2 is docked with the external feeding device. After that, the entire equipment is started, and the feeding device transports the carbon black to be crushed into the interior of the body 1 through the feeding pipe 2. At the same time, the crushing mechanism 3 receives the fallen carbon black and cooperates with the adjusting mechanism 4 to crush the carbon black on both sides. The carbon black dust after being crushed into powder will be driven by the guiding mechanism 6 and contact the filtering mechanism 5, so that the carbon black with the particle size meeting the standard in the dust is sucked away from the filtering mechanism 5 by the external exhaust device, while the carbon black with larger particle size falls back to the top of the crushing mechanism 3, and so on. When the worker wants to change the mesh size of the carbon black processed by this equipment, the worker starts the adjusting mechanism 4, causing the adjusting mechanism 4 to move vertically, thereby changing the gap with the crushing mechanism 3, causing the mesh size of the carbon black ground by the crushing mechanism 3 to change. At the same time, as the adjusting mechanism 4 operates, the filtering mechanism 5 will also operate, and change the mesh size of the filtered carbon black, so as to match the adjusting mechanism 4.

[0048] Reference Figures 2 to 3 、 Figure 5 In a preferred embodiment, the crushing mechanism 3 further includes a plurality of groups of rotors 304 evenly distributed and rotatably installed inside the frame 303 .

[0049] The feeding device transports the carbon black to be crushed into the interior of the machine body 1 through the feeding pipe 2, and the carbon black will fall between the crushing mechanism 3 and the adjusting mechanism 4. At this time, the electric turntable 302 starts and drives the frame 303 to rotate. The rotating frame 303 will drive all the rotors 304 to rotate. While the rotor 304 revolves, it will rotate due to the influence of friction. At the same time, the two sides of the rotor 304 will be pressed close to the adjusting mechanism 4 and grind the carbon black, causing the carbon black to become dust.

[0050] Reference Figure 2 、 Figures 4 and 5 In a preferred embodiment, the adjustment mechanism 4 further includes a plurality of groups of arc surface portions 404 provided on the close surfaces of the outer grinding ring 401 and the inner grinding member 402. The arc surface portions 404 are arc surface structures inclined outward from bottom to top. Both sides of each group of rotors 304 are distributed correspondingly to the arc surface portions 404. Two electric push rods 405 are symmetrically installed on the top of the body 1. The output ends of the electric push rods 405 vertically penetrate the interior of the body 1 and are fixedly connected to the top of the inner grinding member 402.

[0051] The feeding device conveys the carbon black to be crushed into the interior of the machine body 1 through the feeding pipe 2. The carbon black falls between the crushing mechanism 3 and the regulating mechanism 4. At this time, the electric control turntable 302 starts and drives the frame 303 to rotate. The rotating frame 303 drives all the rotors 304 to rotate. While the rotors 304 revolve, they rotate due to the influence of friction. At the same time, the two sides of the rotors 304 are pressed close to the several groups of arc surfaces 404 on the side of the outer grinding ring 401 and the inner grinding member 402, and the carbon black is ground, causing the carbon black to become dust. When the worker wants to change the mesh size of the carbon black crushed by this equipment, the worker starts the electric push rod 405, causing the output end of the electric push rod 405 to extend or contract slightly. While contracting, it will pull the outer grinding ring 401 and the inner grinding part 402, causing several groups of arc surface parts 404 located on the side of the outer grinding ring 401 and the inner grinding part 402 to move synchronously, thereby changing the contact surface gap between the arc surface part 404 and the rotor 304. When the arc surface part 404 and the rotor 304 are relatively squeezed, the obtained carbon black mesh size will also change accordingly.

[0052] Among them, a number of connecting plates 403 are fixedly connected between the outer grinding ring 401 and the inner grinding part 402. The connecting plates 403 are distributed above the frame 303. The connecting plates 403 connect the outer grinding ring 401 and the inner grinding part 402 into a whole, and move synchronously; and a bevel portion 4021 is provided at the bottom of the inner grinding part 402. The bevel portion 4021 and the material guide port 603 are distributed correspondingly. The ground carbon black dust will slide freely along the surface of the bevel portion 4021, and thus slide out of the material guide port 603.

[0053] Furthermore, a plurality of scrapers 406 are fixed to the opposing surfaces of the outer grinding ring 401 and the inner grinding member 402. Each scraper 406 is distributed at the top of an arc surface portion 404. When the equipment stops crushing the carbon black, the output end of the electric push rod 405 continues to extend downward, causing the plurality of scrapers 406 on the outside of the outer grinding ring 401 and the inner grinding member 402 to be squeezed and contacted with the rotor 304. At this time, as the rotor 304 rotates, the surface of the rotor 304 will be scraped and cleaned by the scrapers 406.

[0054] Reference Figure 2 、 Figures 6 to 9 In a preferred embodiment, the filtering mechanism 5 also includes a bottom plate 503 rotatably mounted on the bottom of the inner sieve drum 502, and the two ends of the bottom plate 503 are respectively fixedly connected to the output ends of the two electric push rods 405. A threaded groove 504 is provided on the outer side of the bottom of the bottom plate 503. The inner sieve drum 502 is threadedly connected to the inner wall of the outer sieve drum 501 through the threaded groove 504. The top of the outer sieve drum 501 is fixedly connected with a cover drum 505, and the cover drum 505 passes through the top of the body 1.

[0055] As the external exhaust device connected to the cover drum 505 is running, the carbon black dust that has been ground and settled to the bottom of the interior of the body 1 will be transported upward along the material guide mechanism 6 until it reaches the side of the outer sieve drum 501. At this time, the carbon black dust with particle size that meets the standard will directly pass through the outer sieve drum 501 and be extracted from the inside of the cover drum 505, while the carbon black dust with larger particle size will settle down again, and this cycle will repeat; and as the output end of the electric push rod 405 is pulled upward, the output end of the electric push rod 405 will synchronously drive the bottom plate 503, causing the bottom plate 503 to pull the inner sieve drum 502. The inner sieve drum 502 is affected by the thread groove 504 and will rotate slightly while moving upward, causing the filter discs of the outer sieve drum 501 and the inner sieve drum 502 to be misaligned, thereby changing the number of carbon black meshes that can pass through the inside of the filtering mechanism 5, and adapting to the change in the grinding mesh number of the adjustment mechanism 4.

[0056] Reference Figures 2 to 3 、 Figure 5 In a preferred embodiment, the material guiding mechanism 6 includes a plurality of air inlets 601 evenly opened on the outside of the bottom of the body 1, and a material guiding cavity 602 is vertically opened on the inner wall of the body 1. The bottom end of the material guiding cavity 602 is connected to the air inlet 601, and the top end of the material guiding cavity 602 passes through the inner wall of the body 1 and is distributed correspondingly to the filtering mechanism 5 in the horizontal direction. A plurality of material guiding ports 603 are evenly opened at the connection between the electric control turntable 302 and the frame 303, and the material guiding port 603 and the material guiding cavity 602 are connected.

[0057] As the external exhaust device connected to the cover cylinder 505 operates, the outside air will enter the interior of the equipment through the air inlet 601, and drive the carbon black dust that has settled to the bottom of the body 1 after grinding to move out from the material guide port 603, and move upward along the material guide cavity 602 until it reaches the side of the outer sieve cylinder 501 and moves toward the outer sieve cylinder 501.

[0058] Among them, a number of material guiding inclined tubes 604 are evenly arranged on the upper inner wall of the body 1, and the material guiding inclined tubes 604 are connected with the top of the material guiding cavity 602, and the material guiding inclined tubes 604 and the outer sieve drum 501 are correspondingly distributed in the horizontal direction. At the same time, the inclination direction of the material guiding inclined tubes 604 is opposite to the filter disc of the outer sieve drum 501. The carbon black dust ejected from the top of the material guiding cavity 602 will be ejected obliquely along the material guiding inclined tubes 604, and the inclination direction of the material guiding inclined tubes 604 is opposite to the filter disc of the outer sieve drum 501. The dust after ejection directly collides with the filter disc of the outer sieve drum 501, so that it is better filtered, and the carbon black powder ejected obliquely from the material guiding inclined tubes 604 is spirally distributed in the body 1 (such as Figure 10 As shown by the arrow, the large particles of carbon black powder have more time to settle.

[0059] Working principle: When in use, the top of the filter mechanism 5 is connected to the external exhaust device, and the feed pipe 2 is connected to the external feeding device. After that, the entire equipment is started, and the feeding device transports the carbon black to be crushed into the interior of the machine body 1 through the feed pipe 2. The carbon black will fall between the crushing mechanism 3 and the adjustment mechanism 4. At this time, the electric turntable 302 is started and drives the frame 303 to rotate. The rotating frame 303 will drive all the rotors 304 to rotate. While the rotor 304 revolves, it will rotate due to the influence of friction. At the same time, the two sides of the rotor 304 will squeeze close to the several groups of arc surfaces 404 on the side of the outer grinding ring 401 and the inner grinding part 402 and grind the carbon black (such as Figure 5 As shown), the carbon black turns into dust, and the carbon black dust settles at the bottom of the body 1;

[0060] At this time, with the operation of the external exhaust device connected to the cover cylinder 505, the outside air will enter the interior of the equipment through the air inlet 601, and drive the carbon black dust that has settled to the bottom of the body 1 after grinding to move out from the material guide port 603, and be sucked upward along the material guide cavity 602, and be sprayed obliquely from the material guide inclined tube 604. The obliquely sprayed carbon black dust will be spirally distributed on the top of the body 1. Due to the negative pressure suction at the outer sieve cylinder 501, the spirally distributed carbon black dust will approach the outer sieve cylinder 501. At this time, the carbon black dust that meets the particle size standard will directly pass through the outer sieve cylinder 501 and be sucked out from the inside of the cover cylinder 505, while the carbon black dust with larger particle size will settle down again. This reciprocating process completes the ultra-fine grinding process of carbon black.

[0061] When the worker wants to change the mesh size of the carbon black crushed by the equipment, the worker starts the electric push rod 405, causing the output end of the electric push rod 405 to extend or contract slightly. While contracting, it will pull the outer grinding ring 401 and the inner grinding piece 402, causing several groups of arc surface parts 404 on the side of the outer grinding ring 401 and the inner grinding piece 402 to move synchronously, thereby reducing the contact surface gap between the arc surface part 404 and the rotor 304. When the arc surface part 404 and the rotor 304 are relatively squeezed, the carbon black obtained is The mesh size will also change accordingly, and as the output end of the electric push rod 405 is pulled upward, the output end of the electric push rod 405 will synchronously drive the bottom plate 503, causing the bottom plate 503 to pull the inner sieve drum 502. The inner sieve drum 502 is affected by the thread groove 504 and will rotate slightly while moving upward, causing the filter discs of the outer sieve drum 501 and the inner sieve drum 502 to be misaligned, thereby changing the mesh size of the carbon black that can pass through the inside of the filter mechanism 5, and adapting to the change in the grinding mesh size of the adjustment mechanism 4.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
