Description

Technical Field

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

[0002] Carbon black, also known as soot, is an amorphous carbon, a light, loose and extremely fine black powder, which can be figuratively understood as soot from the bottom of a pot. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances such as coal, natural gas, heavy oil, and fuel oil under insufficient air conditions.

[0003] During the production of carbon black, it is necessary to crush the carbon black raw materials into different meshes according to the processing requirements. Among them, a ring-roll mill is usually used in the market to crush carbon black. When the existing ring-roll mill processes carbon black, on the one hand, the rotor inside the ring-roll mill can only undergo extrusion grinding with the outer grinding plate, and the grinding area is limited, thus affecting the working efficiency of the equipment; on the other hand, the number of meshes that the traditional ring-roll mill rotor can grind is designed at the factory and cannot be changed according to subsequent needs, resulting in weak adjustability and adaptability of most ring-roll mills. Summary of the Invention

[0004] The present invention discloses an ultrafine mill for producing high-value-added carbon black, aiming to solve the technical problem that the functionality and working efficiency of the equipment for crushing 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 mill for producing high-value-added carbon black, comprising a machine body, a feed pipe connected through the side of the machine body, a crushing mechanism for grinding carbon black is arranged below the interior of the machine body, the crushing mechanism includes a base fixedly installed below the interior of the machine body, an electric control turntable is rotatably installed on the top of the base, and a frame is fixedly installed on the top of the electric control turntable;

[0007] An adjusting mechanism for regulating the crushing mesh is arranged outside the crushing mechanism, the crushing mechanism and the adjusting mechanism are in extrusion contact, the adjusting mechanism includes an outer grinding ring slidably distributed inside the machine body, the outer grinding ring is in contact with the inner wall of the machine body, and an inner grinding part is slidably distributed inside the frame;

[0008] A filtering mechanism for screening carbon black dust is arranged above the interior of the machine body, the filtering mechanism includes an outer sieve tube fixedly installed above the interior of the machine body, and an inner sieve tube is slidably sleeved inside the outer sieve tube;

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

[0010] Through the operation of the crushing mechanism in cooperation with the adjustment mechanism, carbon black of different mesh numbers can be processed according to requirements. At the same time, the filtering mechanism operates synchronously, and is synchronously adjusted and screened according to the mesh number of 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 working efficiency. At the same time, in cooperation with the operation of the adjustment mechanism, carbon black of different mesh numbers can be processed according to requirements, improving the functionality of traditional equipment. And the filtering mechanism operates synchronously, and is synchronously adjusted and screened according to the mesh number of carbon black dust, thereby further improving the functionality of traditional equipment.

[0012] In a preferred solution, the crushing mechanism further includes a number of groups of rotors that are evenly distributed and rotatably installed inside the frame.

[0013] By setting the traditional single-sided rotor grinding structure to a double-sided rotor grinding structure, along with the rotation of the electric control turntable driving the frame, the rotor revolves. At the same time, both sides of the rotor can be in extrusion contact with the adjustment mechanism, so as to utilize the middle area of the traditional ring roller mill. The two sides of the rotor are used to polish carbon black at the same time, thus greatly improving the crushing efficiency and the discharging speed of traditional equipment.

[0014] In a preferred solution, the adjustment mechanism further includes a number of groups of arc surfaces provided on the close surfaces of the outer grinding ring and the inner grinding part. The arc surfaces are arc surface structures that slope outward from bottom to top. Both sides of each rotor are correspondingly distributed with the arc surfaces. Two electric push rods are symmetrically installed at the top of the machine body. The output ends of the electric push rods vertically penetrate into the interior of the machine body and are fixedly connected to the top of the inner grinding part.

[0015] By arranging an outer grinding ring with a number of groups of arc surfaces and an inner grinding part to clamp both sides of the rotor, along with the revolution of the rotor, using the synchronous contact between both sides of the rotor and the outer grinding ring and the inner grinding part, carbon black is crushed from multiple directions, improving the working efficiency. And along with the vertical movement of the outer grinding ring and the inner grinding part, by changing the relative position between the rotor and the arc surface to change the distance between the two, the mesh number of carbon black processed by this equipment can be adjusted according to requirements, greatly improving the functionality of this equipment.

[0016] In a preferred solution, the filtering mechanism further includes a bottom plate rotatably installed at the bottom of the inner sieve cylinder. Both ends of the bottom plate are fixedly sleeved with the output ends of the two electric push rods respectively. 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. A cover cylinder is fixedly connected to the top of the outer sieve cylinder. The cover cylinder penetrates out from the top of the machine body.

[0017] By setting the filtering structure of the traditional device to a double-layer structure composed of an outer sieve cylinder and an inner sieve cylinder, when the electric push rod pulls the outer grinding ring and the inner grinding part to move vertically, the inner sieve cylinder will be driven to move accordingly. The moving inner sieve cylinder will rotate under the drive of the thread groove, so as to be misaligned with the outer sieve cylinder, and sequentially change the mesh number of the carbon black dust that can flow through, so as to adapt to the operation of the adjustment mechanism and further improve the functionality of the device.

[0018] In a preferred solution, a number of groups of scrapers are fixed on the opposite surfaces of the outer grinding ring and the inner grinding part, and each scraper is distributed at the top of an arc surface part.

[0019] By arranging a number of groups of scrapers on the sides of the outer grinding ring and the inner grinding part, along with the movement of the outer grinding ring and the inner grinding part and the rotation of the rotor, the scrapers in contact with the rotor can clean the surface of the rotor, thus further improving the functionality of the device.

[0020] In a preferred solution, the feeding mechanism includes a number of air inlets uniformly opened on the outer side of the bottom of the machine body, a feeding cavity is vertically opened on the inner wall of the machine body, the bottom end of the feeding cavity is connected to the air inlets, the top end of the feeding cavity penetrates out from the inner wall of the machine body and is correspondingly distributed horizontally with the filtering mechanism, and a number of feeding ports are uniformly opened at the connection of the electric control turntable and the frame, and the feeding ports are communicated with the feeding cavity.

[0021] By providing air inlets, a feeding cavity and feeding ports, and utilizing the operation of the filtering mechanism, the air path inside the device is changed, thus ensuring the perfection of the operation of the device.

[0022] In a preferred solution, a number of feeding inclined pipes are uniformly arranged above the inner wall of the machine body, the feeding inclined pipes are connected to the top of the feeding cavity in a penetrating manner, the feeding inclined pipes are correspondingly distributed horizontally with the outer sieve cylinder, and at the same time, the inclination direction of the feeding inclined pipes is opposite to the filter sheet orientation of the outer sieve cylinder.

[0023] By arranging feeding inclined pipes at the top of the feeding cavity for connection, the flow direction of the air path flowing through the inside of the feeding cavity is changed. At the same time, the inclination direction of the feeding inclined pipes is opposite to the filter sheet orientation of the outer sieve cylinder, so that the inclined air path can directly blow the surface of the outer sieve cylinder, thus improving the filtering efficiency of the filtering mechanism.

[0024] As can be seen from the above, an ultrafine pulverizer for producing high-value-added carbon black provided by the present invention has the following technical effects.

[0025] First: By setting the traditional single-sided rotor grinding structure to a double-sided rotor grinding structure, along with the electric control turntable driving the rotor to revolve, both sides of the rotor can be in extrusion contact with the adjusting mechanism at the same time. Thus, the middle area of the traditional ring roller mill can be utilized, and the carbon black can be polished simultaneously on both sides of the rotor, thereby greatly improving the crushing efficiency and discharging speed of the traditional equipment.

[0026] Second: By providing an outer grinding ring with several arc-shaped surfaces and an inner grinding part clamped on both sides of the rotor, along with the vertical movement occurring simultaneously during the revolution of the rotor, the distance between the rotor and the arc-shaped surface is changed by changing their relative positions, so as to adjust the mesh number of the carbon black processed by this equipment according to requirements, greatly improving the functionality of the traditional crushing equipment.

[0027] Third: By providing several groups of scrapers on the side surfaces of the outer grinding ring and the inner grinding part, along with the movement of the outer grinding ring and the inner grinding part and the rotation of the rotor, the scrapers in contact with the rotor can clean the surface of the rotor, thereby further improving the functionality of this equipment.

[0028] Fourth: By setting the filtering structure of the traditional equipment to a double-layer structure composed of an outer sieve cylinder and an inner sieve cylinder, when the electric push rod pulls the outer grinding ring and the inner grinding part to move vertically, the inner sieve cylinder will be driven to move accordingly. The moving inner sieve cylinder will rotate under the drive of the thread groove, so as to be misaligned with the outer sieve cylinder, and successively change the mesh number of the carbon black dust that can pass through. Thus, when adapting to the operation of the adjusting mechanism and changing the mesh number of the processed carbon black, the mesh number of the filtered carbon black can also be changed accordingly, thereby further improving the functionality of this equipment.

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

[0041] An ultrafine pulverizer for producing high-value-added carbon black disclosed by the present invention is mainly applied to the scenario of ultrafine pulverization of carbon black.

[0042] Referring to [[ ]] Figures 1 to 10 An ultrafine pulverizer for producing high-value-added carbon black includes a machine body 1, a feed pipe 2 connected through the side of the machine body 1, and a crushing mechanism 3 for grinding carbon black is arranged below the interior of the machine body 1. The crushing mechanism 3 includes a base 301 fixedly installed below the interior of the machine body 1, an electric control turntable 302 rotatably installed on the top of the base 301, and a frame 303 fixedly installed on the top of the electric control turntable 302;

[0043] An adjusting mechanism 4 for regulating the crushing fineness is arranged outside the crushing mechanism 3. The crushing mechanism 3 and the adjusting mechanism 4 are in extrusion contact. The adjusting mechanism 4 includes an outer grinding ring 401 slidably distributed inside the machine body 1. The outer grinding ring 401 is in contact with the inner wall of the machine body 1, and an inner grinding part 402 is slidably distributed inside the frame 303;

[0044] A filtering mechanism 5 for screening carbon black dust is arranged above the interior of the machine body 1. The filtering mechanism 5 includes an outer sieve cylinder 501 fixedly installed above the interior of the machine body 1, and an inner sieve cylinder 502 is slidably sleeved inside the outer sieve cylinder 501;

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

[0046] Through the operation of the crushing mechanism 3 in cooperation with the adjusting mechanism 4, carbon black of different mesh numbers can be processed according to requirements. At the same time, the filtering mechanism 5 operates synchronously, and is synchronously adjusted and screened according to the mesh number of carbon black dust.

[0047] In this embodiment: Before use, the top of the filtering mechanism 5 is docked with an external air extraction device, and the feeding pipe 2 is docked with an external feeding device. Then the entire device is started. The feeding device conveys the carbon black to be crushed into the interior of the machine body 1 through the feeding pipe 2. At the same time, the crushing mechanism 3 catches the falling 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 material guiding mechanism 6 and contact the filtering mechanism 5, causing the carbon black with qualified particle size in the dust to be drawn away by the external air extraction device from the filtering mechanism 5, while the carbon black with larger particle size falls back to the top of the crushing mechanism 3 again, and so on; When the worker wants to change the mesh number of the carbon black processed by this device, at this time 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 number of the carbon black ground by the crushing mechanism 3 to change. At the same time, along with the operation of the adjusting mechanism 4, the filtering mechanism 5 will operate together and change the mesh number of the filtered carbon black, so as to match the adjusting mechanism 4.

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

[0049] 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 will fall between the crushing mechanism 3 and the adjusting mechanism 4. At this time, the electric control turntable 302 is started to drive the frame 303 to rotate. The rotating frame 303 will drive all the rotors 304 to rotate. While the rotors 304 revolve, they will rotate due to the influence of friction. At the same time, both sides of the rotors 304 will be pressed against and close to the adjusting mechanism 4 to grind the carbon black, causing the carbon black to become powdery.

[0050] Refer to Figure 2 、 Figures 4 to 5 In a preferred embodiment, the adjusting mechanism 4 further includes a number of groups of arc-shaped surfaces 404 provided on the close surfaces of the outer grinding ring 401 and the inner grinding part 402. The arc-shaped surfaces 404 are arc-shaped structures that slope outward from bottom to top. Both sides of each group of rotors 304 are correspondingly distributed with the arc-shaped surfaces 404. Two electric push rods 405 are symmetrically installed on the top of the machine body 1. The output ends of the electric push rods 405 vertically penetrate into the interior of the machine body 1 and are fixedly connected to the top of the inner grinding part 402.

[0051] The feeding device transports the carbon black to be pulverized into the interior of the machine body 1 through the feeding pipe 2. The carbon black will fall between the pulverizing mechanism 3 and the adjusting mechanism 4. At this time, the electric control turntable 302 starts and drives the frame 303 to rotate. The rotating frame 303 will drive all the rotors 304 to rotate. While the rotors 304 revolve, they will rotate due to the influence of friction. At the same time, both sides of the rotors 304 will be pressed against and close to several groups of arc-shaped surfaces 404 on the sides of the outer grinding ring 401 and the inner grinding part 402 to grind the carbon black, causing the carbon black to become powdery. When the worker wants to change the mesh number of the carbon black pulverized by this equipment, the worker starts the electric push rod 405 at this time, 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-shaped surfaces 404 on the sides of the outer grinding ring 401 and the inner grinding part 402 to move synchronously, thereby changing the contact surface gap between the arc-shaped surface 404 and the rotor 304. When the arc-shaped surface 404 and the rotor 304 are relatively pressed, the corresponding mesh number of the obtained carbon black will also change.

[0052] Among them, several 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 for synchronous movement. And the bottom of the inner grinding part 402 is provided with an inclined surface 4021. The inclined surface 4021 and the material guiding port 603 are correspondingly distributed. The pulverized carbon black dust will slide freely along the surface of the inclined surface 4021 and thus slide out from the material guiding port 603.

[0053] Furthermore, several groups of scraping blades 406 are fixedly installed on the opposite surfaces of the outer grinding ring 401 and the inner grinding part 402. Each scraping blade 406 is distributed at the top of an arc-shaped surface 404. After the equipment stops pulverizing the carbon black, the output end of the electric push rod 405 continues to extend downward at this time, causing several groups of scraping blades 406 on the outside of the outer grinding ring 401 and the inner grinding part 402 to be in pressing contact with the rotor 304. At this time, along with the rotation of the rotor 304, the surface of the rotor 304 will be scraped and cleaned by the scraping blades 406.

[0054] Refer to Figure 2 、 Figures 6 to 9 In a preferred embodiment, the filtering mechanism 5 further includes a bottom plate 503 rotatably installed at the bottom of the inner sieve cylinder 502. Both ends of the bottom plate 503 are fixedly sleeved with 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 cylinder 502 is threadedly connected to the inner wall of the outer sieve cylinder 501 through the threaded groove 504. A cover cylinder 505 is fixedly connected to the top of the outer sieve cylinder 501. The cover cylinder 505 penetrates through the top of the machine body 1.

[0055] With the operation of the external exhaust device connected to the hood cylinder 505, the carbon black dust ground and settled below the interior of the machine body 1 at this time will be conveyed upward along the material guiding mechanism 6 until it reaches the side of the outer sieve cylinder 501. At this time, the carbon black dust with qualified particle size will directly pass through the outer sieve cylinder 501 and be sucked away from the interior of the hood cylinder 505, while the carbon black dust with larger particle size will settle downward again, and so on; and while the output end of the electric push rod 405 pulls 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 cylinder 502. Affected by the thread groove 504, the inner sieve cylinder 502 will rotate slightly while moving upward, causing the filter plates of the outer sieve cylinder 501 and the inner sieve cylinder 502 to be misaligned, thereby changing the carbon black mesh number that can pass through the filtering mechanism 5 and adapting to the change in the grinding mesh number of the adjusting mechanism 4.

[0056] Referring to 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 outer side of the bottom of the machine body 1. A material guiding cavity 602 is vertically opened on the inner wall of the machine 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 penetrates out of the inner wall of the machine body 1 and is correspondingly distributed horizontally with the filtering mechanism 5. A plurality of material guiding ports 603 are evenly opened at the connection of the electric control turntable 302 and the frame 303, and the material guiding ports 603 communicate with the material guiding cavity 602.

[0057] With the operation of the external exhaust device connected to the hood cylinder 505, the outside air will enter the equipment through the air inlet 601 at this time, drive the carbon black dust ground and settled below the interior of the machine body 1 to move out from the material guiding port 603, and move upward along the material guiding cavity 602 until it reaches the side of the outer sieve cylinder 501 and moves towards the outer sieve cylinder 501.

[0058] Among them, a plurality of material guiding inclined pipes 604 are evenly arranged above the inner wall of the machine body 1. The material guiding inclined pipes 604 are connected to the top of the material guiding cavity 602 in a penetrating manner. The material guiding inclined pipes 604 are correspondingly distributed horizontally with the outer sieve cylinder 501. At the same time, the inclination direction of the material guiding inclined pipes 604 is opposite to the filter plate orientation of the outer sieve cylinder 501. The carbon black dust ejected from the top of the material guiding cavity 602 will be ejected obliquely along the material guiding inclined pipes 604, and the inclination direction of the material guiding inclined pipes 604 is opposite to the filter plate orientation of the outer sieve cylinder 501. The ejected dust directly impacts and contacts the filter plate of the outer sieve cylinder 501, so as to be better filtered, and the carbon black powder ejected obliquely from the material guiding inclined pipes 604 is spirally distributed in the machine body 1 (as Figure 10 shown by the arrow), so that the large-particle carbon black powder has more time to settle.

[0059] Working principle: When in use, the top of the filtering mechanism 5 is docked with an external air extraction device, and the feeding pipe 2 is docked with an external feeding device. Then, the entire device is started. The feeding device conveys the carbon black to be pulverized into the interior of the machine body 1 through the feeding pipe 2. The carbon black will fall between the pulverizing mechanism 3 and the adjusting mechanism 4. At this time, the electric control 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 rotors 304 revolve, they will rotate due to the influence of friction. At the same time, both sides of the rotors 304 will be in extrusion contact with several groups of arc surfaces 404 on the side surfaces of the outer grinding ring 401 and the inner grinding part 402 and grind the carbon black (as shown in Figure 5 ), causing the carbon black to become powdery. The carbon black powder will settle at the bottom of the machine body 1;

[0060] At this time, with the operation of the external air extraction device connected to the cover cylinder 505, the outside air will enter the equipment through the air inlet 601, and drive the carbon black powder that has settled below the interior of the machine body 1 after grinding to be removed from the material guiding port 603, and be sucked upward along the material guiding cavity 602, and sprayed obliquely from the material guiding inclined pipe 604. The obliquely sprayed carbon black powder will be distributed in a spiral shape on the top of the machine body 1. Due to the negative pressure suction at the outer sieve cylinder 501, the spirally distributed carbon black powder will approach the outer sieve cylinder 501. At this time, the carbon black powder with qualified particle size will directly pass through the outer sieve cylinder 501 and be sucked away from the inside of the cover cylinder 505, while the carbon black powder with larger particle size will settle downward again. This process is repeated to complete the ultrafine pulverization processing of the carbon black;

[0061] And when the worker needs to change the mesh number of the carbon black pulverized by this equipment, at this time, 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 surfaces 404 on the side surfaces of the outer grinding ring 401 and the inner grinding part 402 to move synchronously, thereby reducing the contact surface gap between the arc surfaces 404 and the rotors 304. When the arc surfaces 404 and the rotors 304 are in relative extrusion, the corresponding mesh number of the obtained carbon black will also change. And while 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 cylinder 502. Affected by the thread groove 504, the inner sieve cylinder 502 will rotate slightly while moving upward, causing the filter plates of the outer sieve cylinder 501 and the inner sieve cylinder 502 to be misaligned, thereby changing the mesh number of the carbon black that can pass through the filtering mechanism 5, and adapting to the change in the grinding mesh number of the adjusting mechanism 4.

[0062] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
