Description

Technical Field

[0001] The present invention relates to the technical field of modified pyrolytic carbon black preparation, and particularly relates to a production device for modified pyrolytic carbon black. Background Art

[0002] Carbon black is a black powdery substance formed by the incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. Its main component is elemental carbon, and it contains a small amount of oxygen, hydrogen, sulfur, etc. Carbon black particles are approximately spherical, with a particle size ranging from 10 to 500 μm. Many particles are often fused or aggregated into three-dimensional branched or fibrous aggregates.

[0003] Unmodified pyrolytic carbon black cannot be well dispersed in polymers, and it is difficult to form coupling bonds between the filler and the polymer, thus reducing the vulcanization efficiency and reinforcing performance. The surface modification of pyrolytic carbon black is to use certain chemical substances through a certain process method to react the surface hydroxyl groups of pyrolytic carbon black with the chemical substances, eliminate or reduce the amount of its surface active silanol groups, make the product change from hydrophilic to hydrophobic, and increase its dispersibility in polymers.

[0004] Modified pyrolytic carbon black has excellent properties and is widely used in industries such as rubber, coatings, and plastics. At present, the industrial modification of pyrolytic carbon black mainly adopts the dry method, generally by pulverizing and surface-modifying pyrolytic carbon black powder. Although the dry modification process is simple, when using the dry method for modification, the existing equipment only stirs pyrolytic carbon black singly, and the modifier is usually not evenly distributed, and the effect is not ideal. Summary of the Invention

[0005] The main purpose of the present invention is to provide a production device for modified pyrolytic carbon black, which at least solves the problem of uneven distribution of modifiers in the prior art.

[0006] According to one aspect of the present invention, there is provided a production device for modified pyrolytic carbon black, including: A production tank, whose axis is arranged horizontally, and is provided with a feed inlet and a discharge outlet thereon; A filtration chamber, which is arranged axially in the production tank along the axis of the production tank. Both ends of the filtration chamber are hermetically fixed to both ends of the production tank and are circumferentially covered with filtration holes, and the feed inlet is communicated to the filtration chamber; A stirring shaft, which is arranged axially along the production tank, passes through the production tank and is rotationally sealed with the production tank, and spiral blades are arranged axially on the stirring shaft; A frame, which is used to install the production tank and the stirring shaft; A stirring motor, which is installed on the frame and is used to drive the stirring shaft to rotate.

[0007] In a possible design, a number of grinding balls are arranged in the filtration chamber.

[0008] In one possible design, a number of impact plates are evenly arranged circumferentially inside the filtering cavity.

[0009] In one possible design, it further includes a first rotating motor. A gear ring is provided on the outer wall of the production tank, and a driving gear meshing with the gear ring is provided on the first rotating motor.

[0010] In one possible design, the filtering cavity is integrally conical along the axial direction of the production tank, and the end of the filtering cavity close to the discharge port is the end with a smaller size.

[0011] In one possible design, the stirring shaft is hollow and closed at one end, and a number of air outlet holes are provided on the stirring shaft.

[0012] In one possible design, a temperature regulating cavity surrounded by air bags is provided on the outer wall of the production tank.

[0013] In one possible design, it further includes a cam mechanism. An intake one-way valve communicating with the outside and an exhaust one-way valve communicating with the production tank are provided on the temperature regulating cavity, and the cam abuts against the temperature regulating cavity.

[0014] In one possible design, the belt drive is adopted between the stirring motor and the stirring shaft.

[0015] The present invention also provides a production process for modified pyrolytic carbon black. This process is based on the aforementioned production device for modified pyrolytic carbon black and at least includes the following steps: Step 1: Put pyrolytic carbon black and a modifier into the filtering cavity through the feed port; Step 2: Start the stirring motor to drive the stirring shaft to stir and mix. The qualified modified pyrolytic carbon black enters the space between the production tank and the filtering cavity through the filtering holes; Step 3: After the reaction is completed, stop the stirring motor, open the discharge port, and output the modified pyrolytic carbon black.

[0016] During operation, in the initial state, the axis of the production tank remains relatively horizontal. At this time, modifiers and pyrolytic carbon black are added into the filtration chamber through the feed pipe, and temperature-regulating gas is added into the stirring shaft through the air inlet pipe. Then, the feed pipe is closed, and the stirring motor, the first rotating motor, and the second rotating motor are started. The stirring shaft, the spiral blade, the cam, and the production tank all rotate. The production tank, the filtration chamber rotate in the opposite direction to the stirring shaft and the spiral blade. In this way, a shearing force is formed between the filtration chamber and the stirring shaft, especially between the spiral blade of the stirring shaft, which can increase new dimensions of stirring and mixing, greatly improving the contact, mixing, and reaction rates of the modifier and pyrolytic carbon black. With the rotation of the production tank, the special structure of the filtration chamber will drive the modifier and pyrolytic carbon black to migrate and distribute from one end close to the left bracket to the end far from the left bracket, while the spiral blade just drives the modifier and pyrolytic carbon black to migrate and distribute from the end far from the left bracket to the end close to the left bracket, thus forming multiple cycles and continuous impacts and mixing in the production tank. Additionally, the temperature-regulating gas in the stirring shaft and the temperature-regulating chamber is discharged into the production tank body through the air outlet holes or the one-way air outlet valve, and the pyrolytic carbon black and modifier particles are ground, crushed, and mixed through rolling or collision (collision between grinding balls and collision between grinding balls and the inner wall of the filtration chamber). With the superposition of the conical structure of the filtration chamber and the conveying effect of the spiral blade on the materials in the filtration chamber, new dimensions of stirring and mixing are increased, greatly improving the contact, mixing, and reaction rates of the modifier and pyrolytic carbon black, and enhancing the utilization rate of the pyrolytic carbon black and modifier. After the reaction is completed, the stirring motor, the first rotating motor, and the second rotating motor are turned off, and the discharge pipe is opened.

[0017] Compared with the prior art, the principles and effects of the present invention are as follows: (1) In the present invention, when the stirring shaft and the spiral blade rotate, the modifiers and pyrolytic carbon black in the entire production tank are dynamically changing and distributing. This can not only intensify the mutual impact between the pyrolytic carbon black and the modifier, improve the mixing and stirring effects, prevent the modifier from depositing or accumulating on the inner wall of the production tank, bring a turbulent flow effect to the pyrolytic carbon black, improve the utilization rate of the pyrolytic carbon black and the modifier, but also play an auxiliary heating effect through the impact of the pyrolytic carbon black and the modifier. At the same time, it can also increase the dimensions of stirring and mixing, greatly improving the contact, mixing, reaction rate, and effect of the modifier and pyrolytic carbon black.

[0018] (2) The rotation of the production tank in the present invention can churn and stir the modifier and pyrolytic carbon black, enabling the modifier and pyrolytic carbon black to be fully contacted and mixed, and improving the reaction rate. It should be particularly noted here that the rotation direction of the production tank is opposite to that of the stirring shaft. In this way, a shearing force is formed between the production tank and the stirring shaft, especially between the spiral blade of the stirring shaft, which can increase new dimensions of stirring and mixing, greatly improving the contact, mixing, and reaction rates of the modifier and pyrolytic carbon black.

[0019] (3) The special structure of the filtration chamber of the present invention can form a taper or gradient in the filtration chamber, so that during the reaction process, it is convenient for the modifier and pyrolytic carbon black to move from one end far away from the right support to the end close to the right support. Correspondingly, this is just opposite to the conveying direction of the spiral blade, so that a convection effect can be formed to ensure that the modifier and pyrolytic carbon black can be fully contacted and mixed, ensuring the reaction time and improving the reaction rate.

[0020] (4) The settings of the grinding balls and collision plates of the present invention achieve the grinding, pulverization and mixing of pyrolytic carbon black and modifier particles through rolling or collision (collision between grinding balls and collision between grinding balls and the inner wall of the filtration chamber). Superimposing the conical structure of the filtration chamber and the conveying effect of the spiral blade on the materials in the filtration chamber enables the trajectory of the grinding balls to touch the mixing area of the modifier and pyrolytic carbon black, increasing new dimensions of stirring and mixing, greatly improving the contact, mixing and reaction rates of the modifier and pyrolytic carbon black, and improving the utilization rate of pyrolytic carbon black and modifier.

[0021] (5) The gas in the stirring shaft and temperature regulating chamber of the present invention is discharged from the air outlet or one-way air valve into the production tank, which can not only intensify the mutual impact between pyrolytic carbon black and modifier, improve the mixing and stirring effect, avoid the deposition or accumulation of the modifier on the inner wall of the production tank, bring a turbulent flow effect to the pyrolytic carbon black, improve the utilization rate of pyrolytic carbon black and modifier, but also achieve a temperature regulating effect through the impact of pyrolytic carbon black and modifier, and increase the dimensions of stirring and mixing, greatly improving the contact, mixing and reaction rates and effects of the modifier and pyrolytic carbon black.

[0022] (6) The device of the present invention not only has high efficiency and good effect in preparing modified pyrolytic carbon black, but also has high utilization rate of the modifier and pyrolytic carbon black, and high comprehensive benefits, which is worthy of promotion. Description of the Drawings

[0024] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the following drawings are only some embodiments of the present application. For those skilled in the art, other drawings can be obtained based on these drawings without creative efforts.

[0025] Figure 1 It shows a three-dimensional view of a modified pyrolytic carbon black production device proposed in an embodiment of the present application; Figure 2 It shows a three-dimensional view of a modified pyrolytic carbon black production device proposed in an embodiment of the present application; Figure 3 It shows a front view of a modified pyrolytic carbon black production device proposed in an embodiment of the present application; Figure 4 The bottom view of a modified pyrolytic carbon black production device proposed by an embodiment of the present application is shown; Figure 5 The right view of a modified pyrolytic carbon black production device proposed by an embodiment of the present application is shown; Figure 6 Shown is Figure 5 the sectional view taken along line A-A of Figure 7 Shown is Figure 5 the sectional view taken along line B-B of Figure 8 The rear view of a modified pyrolytic carbon black production device proposed by an embodiment of the present application is shown; Figure 9 Shown is Figure 8 the sectional view taken along line D-D of Detailed implementation manners

[0026] To further illustrate the embodiments, the present invention provides accompanying drawings, which are a part of the disclosure of the present invention. They are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] For the sake of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation shown in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures".

[0028] Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0029] In addition, it should be noted that the use of terms such as "first", "second" etc. to limit components is only for the convenience of differentiating the corresponding components. Without further statement, the above terms have no special meanings, so they cannot be understood as limiting the protection scope of the present invention.

[0030] Explanation of reference numerals: Production tank 1, temperature control chamber 2, stirring shaft 3, gear ring 4, driven pulley 5, driving gear 6, cam 7, intake check valve 8, discharge port 9, feed port 10, spiral blade 11, filtration chamber 12, filtration holes 13, impact plate 14, grinding balls 15.

[0031] According to an embodiment of the present invention, a modified pyrolytic carbon black production device is provided. As Figures 1 - 9 shown, the modified pyrolytic carbon black production device includes: A production tank 1, whose axis is arranged horizontally, and is provided with a feed port 10 and a discharge port 9 thereon. The production tank 1 provides a stable reaction site for the preparation of modified pyrolytic carbon black. A feed pipe is provided at the feed port 10, and a discharge pipe is provided at the discharge port 9; A filtration chamber 12 is axially arranged in the production tank 1 along the axis of the production tank 1. Both ends of the filtration chamber 12 are hermetically fixed to both ends of the production tank 1 and are circumferentially covered with filtration holes 13. The feed port 10 communicates with the filtration chamber 12. The setting of the filtration chamber 12 facilitates the crushing, stirring and mixing of pyrolytic carbon black and modifier. Only the modified pyrolytic carbon black that meets the set requirements can enter the space enclosed by the filtration holes 13 and the production tank 1 through the filtration holes 13. The modifier and pyrolytic carbon black entering from the feed port 10 are mainly crushed and mixed in the filtration chamber 12; A stirring shaft 3 is arranged axially along the production tank 1, passes through the production tank 1 and is rotationally sealed with the production tank 1. Spiral blades 11 are arranged axially on the stirring shaft 3. The spiral blades 11 on the stirring shaft 3 can not only be used to stir pyrolytic carbon black and modifier, accelerate their stirring and mixing and reaction, but also realize the migration of pyrolytic carbon black and modifier in the production tank 1, which is beneficial to the uniform distribution and full reaction of pyrolytic carbon black and modifier in the production tank 1; A frame for installing the production tank 1 and the stirring shaft 3; the setting of the frame greatly facilitates the installation and fixation of the production tank 1 and the stirring shaft 3, and can be customized and moved according to the production site. The frame can be made of steel profiles, and specifically, a truss structure or other strengthening structures can be used to enhance the structural strength.

[0032] A stirring motor is installed on the frame and is used to drive the stirring shaft 3 to rotate; a belt drive is provided between the stirring motor and the stirring shaft 3. Specifically, one end of the stirring shaft 3 extends out of the production tank 1 and is key-connected with a driven pulley 5, and a driving pulley is key-connected to the stirring motor. The driving pulley drives the driven pulley 5 to rotate through a belt (not shown in the figure), and then the stirring motor drives the stirring shaft 3 to rotate.

[0033] Specifically, the production tank 1 body, the stirring shaft 3 and the spiral blades 11, etc. are all made of steel. Of course, stainless steel can also be used and a polyethylene coating or a polytetrafluoroethylene coating can be applied on its surface to improve the anti-sticking performance of the production tank 1 body, the stirring shaft 3 and the spiral blades 11, etc.

[0034] As Figure 1 , Figure 2 , Figure 3 shown, wherein the frame includes a left bracket and a right bracket arranged at intervals. One end of the stirring shaft 3 is rotatably connected to the left bracket, and the other end of the stirring shaft 3 is rotatably connected to the right bracket. The stirring motor is installed on the right bracket. The purpose of setting the whole frame like this is that when the stirring shaft 3 and the spiral blade 11 rotate, the modifier and the pyrolytic carbon black in the whole production tank 1 are dynamically changing and dynamically distributed. It can not only intensify the mutual impact between the pyrolytic carbon black and the modifier, improve the mixing and stirring effects, avoid the deposition or accumulation of the modifier on the inner wall of the production tank 1, bring a turbulent flow effect to the pyrolytic carbon black, improve the utilization rate of the pyrolytic carbon black and the modifier, but also play an auxiliary heating effect through the impact of the pyrolytic carbon black and the modifier, and can also increase the stirring and mixing dimensions, greatly improving the contact, mixing and reaction rate and effect of the modifier and the pyrolytic carbon black.

[0035] Among them, a first rotating motor is also provided on the right bracket for driving the production tank 1 to rotate. Specifically, a gear ring 4 is provided on the outer wall of the production tank 1, and a driving gear 6 meshing with the gear ring 4 is provided on the first rotating motor. The first rotating motor drives the gear ring 4 and the production tank 1 to rotate through the driving gear 6. The rotation of the production tank 1 can tumble and stir the modifier and the pyrolytic carbon black, so that the modifier and the pyrolytic carbon black can be fully contacted and mixed, improving the reaction rate. It should be particularly noted here that the rotation direction of the production tank 1 is opposite to the rotation direction of the stirring shaft 3. In this way, a shearing force is formed between the production tank 1 and the stirring shaft 3, especially the spiral blade 11 of the stirring shaft 3, which can increase new stirring and mixing dimensions and greatly improve the contact, mixing and reaction rate of the modifier and the pyrolytic carbon black.

[0036] It should be noted that, as Figure 5 , Figure 6 shown, the filter chamber 12 is integrally conical along the axial direction of the production tank 1. Specifically, the taper can be set between 1:(5 - 10). The end of the inclined conical filter chamber 12 close to the discharge port 9 is the end with a smaller size. In this embodiment, the size of the filter chamber 12 gradually decreases from the end close to the right bracket to the end close to the left bracket. In this way, not only can a taper or gradient be formed in the filter chamber 12, so that during the reaction process, it is convenient for the modifier and the pyrolytic carbon black to move from the end far from the right bracket to the end close to the right bracket. Correspondingly, this is just opposite to the conveying direction of the spiral blade 11, so that a convection effect can be formed to ensure that the modifier and the pyrolytic carbon black can be fully contacted and mixed, ensure the reaction time, and improve the reaction rate. Furthermore, the whole production tank 1 can be set to be inclined at a small angle, specifically, it can be set to an angle of 3 - 5 degrees with the horizontal plane. Such an angle is both smaller than the cone angle of the filter chamber 12 and can facilitate the pyrolytic carbon black modified into the space surrounded by the filter chamber 12 and the production tank 1 to be discharged through the discharge port 9.

[0037] As shown in Figure 5 , Figure 6 , Figure 7 , Figure,[[]]END]] Figure 9 To further improve the crushing, stirring, and mixing capabilities of the filtration chamber 12 for cracked carbon black and the modifier, a number of grinding balls 15 are provided inside the filtration chamber 12. The grinding balls 15 are solid steel balls. A number of impact plates 14 are evenly arranged circumferentially inside the filtration chamber 12. Specifically, the arrangement of the grinding balls 15 enables them to roll inside the filtration chamber 12, and the cracking carbon black and modifier particles are ground, crushed, and mixed by rolling or collision (collision between the grinding balls 15 and collision between the grinding balls 15 and the inner wall of the filtration chamber 12). With the superimposed conical structure of the filtration chamber 12 and the conveying effect of the spiral blade 11 on the materials inside the filtration chamber 12, the trajectory of the grinding balls 15 can reach the mixing area of the modifier and cracked carbon black, adding new stirring and mixing dimensions, greatly improving the contact, mixing, and reaction rates of the modifier and cracked carbon black, and enhancing the utilization rate of cracked carbon black and the modifier. Further, the setting of the impact plates 14 can not only increase the collision between the impact plates 14 and the grinding balls 15, further improving the contact, mixing, and reaction rates and effects of the modifier and cracked carbon black, but also increase the height of the grinding balls 15 rotating with the filtration chamber 12, thereby increasing the potential energy of the grinding balls 15 and enhancing the grinding, crushing, and mixing effects and efficiencies on the cracked carbon black and modifier particles caused by rolling or collision. Further, raised wear-resistant patterns are provided on the inner wall of the filtration chamber 12 and the surface of the impact plates 14 to enhance the impact, rolling, grinding, or friction effects with the grinding balls 15, cracked carbon black, and modifier, adding new stirring and mixing dimensions, greatly improving the contact, mixing, and reaction rates of the modifier and cracked carbon black, and enhancing the utilization rate of cracked carbon black and the modifier.

[0038] Among them, as shown in Figure 6 , Figure 7 The stirring shaft 3 is hollow and closed at one end. A number of air outlet holes are provided on the stirring shaft 3. An air temperature adjustment chamber 2 surrounded by air bags is provided on the outer wall of the production tank 1. The hollow stirring shaft 3 and the air temperature adjustment chamber 2 can adjust the temperature inside the production tank 1 to a temperature suitable for the reaction of cracked carbon black and the modifier, thereby improving the reaction rate and reaction effect. In at least one embodiment, the air temperature adjustment chamber 2 is surrounded by rubber seals. Specifically, it can be silicone rubber, fluororubber, or fluorosilicone rubber, etc., which not only has acid and temperature resistance properties but also has good elasticity. An air inlet pipe communicating with the stirring shaft 3 is provided outside the production tank 1. The setting of the air inlet pipe facilitates the input of the temperature adjustment gas, which is the main source of the temperature adjustment gas. The air inlet pipe and the stirring shaft 3 can be connected through a rotating joint, which can not only stably input the temperature adjustment gas but also does not affect the normal operation of the stirring shaft 3. At the same time, the input of the temperature adjustment gas is also suitable for drying the carbon black and the modifier, thereby improving their fluidity and dispersion ability.

[0039] Furthermore, as shown in Figure 1 , Figure 2 , Figure 5 , Figure 7 , it further includes a cam 7 mechanism. The cam 7 mechanism includes a cam 7 and a second rotating motor for driving the cam 7 to rotate. The second rotating motor is fixed on the frame. An intake one-way valve 8 communicating with the outside and an outlet one-way valve communicating with the production tank 1 are provided on the temperature control chamber 2. The cam 7 abuts against the temperature control chamber 2. The outlet one-way valve can only allow the gas in the temperature control chamber 2 to enter the production tank 1 from the temperature control chamber 2, and the intake one-way valve 8 can only allow air to enter the temperature control chamber 2 from the outside. When the cam 7 rotates and squeezes the temperature control chamber 2, the gas in the temperature control chamber 2 is discharged to the production tank 1 through the outlet one-way valve, which can not only intensify the mutual impact between the pyrolytic carbon black and the modifier, improve the mixing and stirring effect, avoid the deposition or accumulation of the modifier on the inner wall of the production tank 1, bring a turbulent flow effect to the pyrolytic carbon black, improve the utilization rate of the pyrolytic carbon black and the modifier, at the same time, can also play a temperature control effect through the impact of the pyrolytic carbon black and the modifier, and can also increase the mixing and stirring dimension, greatly improving the contact, mixing and reaction rate and effect of the modifier and the pyrolytic carbon black; and it should be particularly noted that as the gas in the temperature control chamber 2 is discharged to the production tank 1 through the outlet one-way valve, the temperature control chamber 2 gradually becomes shriveled as a whole, and air enters the temperature control chamber 2 from the outside through the intake one-way valve 8, and so on in a cycle. There is a certain leakage rate in the production tank 1 itself. Of course, in case of emergency, an air outlet can be provided on the production tank 1, and a filter layer such as filter cotton is provided at the air outlet, only allowing the gas to be discharged to avoid excessive pressure in the production tank 1.

[0040] During operation, in the initial state, the axis of the production tank 1 remains relatively horizontal. At this time, a modifier and pyrolytic carbon black are added into the filtration chamber 12 through the feed pipe, and at the same time, a temperature-regulating gas is added into the stirring shaft 3 through the air inlet pipe. Then, the feed pipe is closed, and the stirring motor, the first rotating motor, and the second rotating motor are started. The stirring shaft 3, the spiral blades 11, the cam 7, and the production tank 1 all rotate. The production tank 1, the filtration chamber 12 rotate in the opposite direction to the stirring shaft 3 and the spiral blades 11. In this way, a shearing force is formed between the filtration chamber 12 and the stirring shaft 3, especially between the spiral blades 11 of the stirring shaft 3, which can increase new dimensions of stirring and mixing, greatly improving the contact, mixing, and reaction rates of the modifier and pyrolytic carbon black. With the rotation of the production tank 1, the special structure of the filtration chamber 12 will drive the modifier and pyrolytic carbon black to migrate and distribute from one end close to the left support to the end far from the left support, while the spiral blades 11 just drive the modifier and pyrolytic carbon black to migrate and distribute from the end far from the left support to the end close to the left support, thus forming multiple cycles and continuous impact and mixing in the production tank 1. Additionally, the temperature-regulating gas in the stirring shaft 3 and the temperature-regulating chamber 2 is discharged from the air outlet holes or the one-way air outlet valves into the production tank 1, and the pyrolytic carbon black and modifier particles are ground, crushed, and mixed through the collision between the grinding balls 15 and the collision between the grinding balls 15 and the inner wall of the filtration chamber 12. With the conical structure of the filtration chamber 12 and the conveying effect of the spiral blades 11 on the materials in the filtration chamber 12, new dimensions of stirring and mixing are increased, greatly improving the contact, mixing, and reaction rates of the modifier and pyrolytic carbon black, and improving the utilization rate of the pyrolytic carbon black and modifier. After the reaction is completed, the stirring motor, the first rotating motor, and the second rotating motor are turned off, and the discharge pipe is opened to output the modified pyrolytic carbon black.

[0041] The present invention also provides a production process for modified pyrolytic carbon black, which is based on the aforementioned production device for modified pyrolytic carbon black and at least includes the following steps: Step 1: Put the pyrolytic carbon black and the modifier into the filtration chamber through the feed port. Step 2: Start the stirring motor to drive the stirring shaft to stir and mix. The qualified modified pyrolytic carbon black enters the space between the production tank and the filtration chamber through the filtration holes. Step 3: After the reaction is completed, stop the stirring motor and open the discharge port to output the modified pyrolytic carbon black.
