Description

Technical Field

[0001] This invention relates to the field of carbon black ink production and preparation, and more specifically, to an equipment and method for producing corrosion-resistant carbon black ink. Background Technology

[0002] Carbon black ink, as an important black pigment formulation, is widely used in printing, writing, and coding. Carbon black itself possesses high specific surface area, high blackness, excellent tinting strength, and good chemical stability, making it an ideal material for manufacturing high-performance black inks. Traditional carbon black ink production processes typically involve mixing, stirring, and grinding carbon black powder with binders, solvents, and various additives in a reaction vessel, ultimately obtaining the finished ink through filtration. Adding specific types of carbon black and increasing the grinding precision during production can improve the corrosion resistance of the finished product.

[0003] In existing production processes, the grinding process generates a large amount of heat locally in the solution, which cannot be quickly dispersed throughout the entire reactor. This results in locally high temperatures that reduce product activity and induce unwanted chemical reactions, thus affecting product quality. In addition, after grinding and stirring, filtration is often required separately, which increases the number of production steps. Summary of the Invention

[0072] The vessel body jacket wraps around the outside of the reactor.

[0073] An electric heating element is installed inside the jacket of the vessel body to heat the liquid inside the jacket of the vessel body;

[0074] A liquid inlet valve is located at the upper end of the jacket of the vessel body;

[0075] The liquid outlet valve is located at the lower end of the jacket of the vessel body.

[0076] This invention also provides a method for using equipment for producing corrosion-resistant carbon black ink, comprising the following steps:

[0077] S1. Introduce the liquid into the jacket of the reactor body through the inlet valve, start the electric heating tube to bring the reactor to a suitable temperature, and put the reactants into the reactor through the feed valve.

[0078] S2. Start the drive motor to drive the first rotating shaft to rotate. The first rotating shaft drives the stirring assembly to rotate via the rotating block and rotating cylinder. At the same time, the rotating cylinder drives the upper rotating disk to rotate, thereby fully stirring the solution in the reaction vessel.

[0079] S3. While stirring, the third connecting shaft rotates synchronously, activating the electromagnetic clutch and stopping the bidirectional lead screw. This causes the threaded ring sleeve to rotate relative to the bidirectional lead screw, resulting in the threaded ring sleeve, the second connecting shaft, and the square electromagnet moving up and down along the direction of the bidirectional lead screw. The square electromagnet and the dovetail electromagnet are activated, attracting each other and causing the dovetail electromagnet to move up and down along the second dovetail slide. As the dovetail electromagnet moves, it drives the first gear to rotate along the fixed rack, which in turn drives the hollow cylinder to rotate via the gear ring. Simultaneously, the gear ring drives the sun gear to rotate in the opposite direction via the planetary carrier. This causes the grinding rod to rotate in the opposite direction to the hollow cylinder, resulting in the grinding balls colliding randomly and grinding the solution. Because the grinding part rotates with the rotating cylinder and moves up and down simultaneously, the heat generated during grinding quickly moves to all corners of the solution.

[0080] S4. After grinding is complete, activate the first and second circular electromagnets, causing them to repel each other. This moves the hexagonal prism downwards, disengaging it from the hexagonal slot, preventing the lower rotating disk from following the upper rotating disk. Then, quickly shut off the power to the first and second circular electromagnets to eliminate the repulsive force. Under the action of the spring, the adjusting rod and the hexagonal prism move upwards. After the hexagonal slot rotates 60 degrees, it reconnects with the hexagonal prism, causing the lower rotating disk to rotate via the hexagonal prism and adjusting rod. At this point, the lower rotating disk has a 60-degree angle difference with the upper rotating disk, aligning the first and second arc-shaped filter tanks on the same straight line, separated only by a filter screen. This allows the ground solution to flow through the filter screen to the bottom of the reaction vessel. After filtration, activate the first and second circular electromagnets again, creating another 60-degree angle difference between the lower rotating disk and the upper rotating disk. This disconnects the first and second arc-shaped filter tanks, creating a sealed environment and preventing unreacted ground solution from flowing out.

[0081] S5. Open the discharge valve to discharge the filtered finished solution.

[0082] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0083] By incorporating a grinding section that follows the rotating cylinder via a moving drive section, and simultaneously moving up and down along the rotating cylinder under the action of the moving drive section, the large amount of heat generated during grinding is not only affected in a localized area of ​​the solution, but is diffused throughout the solution along with the grinding section, thereby diluting the heat. Furthermore, grinding in motion can reach every corner of the solution, resulting in more thorough grinding. Attached Figure Description

Detailed Implementation

[0099] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0100] like Figures 1 to 12As shown, an anti-corrosion carbon black ink production and preparation equipment includes: a reaction vessel 1; further comprising: a feed valve 102 disposed at the top of the reaction vessel 1; a discharge valve 105 disposed at the bottom of the reaction vessel 1; a stirring unit disposed inside the reaction vessel 1; and a rotation drive unit disposed at the center of the top of the reaction vessel 1 and connected to the stirring unit to drive the stirring unit to rotate; the stirring unit includes: a rotating block 401 connected to the rotation drive unit; a rotating cylinder 402 with its top end connected to the rotating block 401; and a grinding unit. 6. A grinding unit is installed inside the reactor 1 and connected to the stirring unit via a moving drive unit; the moving drive unit is connected to the rotating cylinder 402 on the stirring unit to drive the grinding unit 6 to move up and down; a filter unit 5 is installed at the bottom end of the rotating cylinder 402 to filter the ground liquid; a filter adjustment unit is installed inside the filter unit 5 and connected to the filter unit 5 to control the opening and closing of the filter unit 5; an observation unit is installed on the reactor 1 to facilitate observation of the preparation process inside the reactor 1.

[0101] In this embodiment of the invention, a grinding section 6 is provided that rotates along with the rotating cylinder 402 via a moving drive unit. Simultaneously, under the action of the moving drive unit, it moves up and down along the rotating cylinder 402. This ensures that when grinding generates a large amount of heat, it does not only affect a localized part of the solution but also diffuses throughout the solution with the grinding section 6, thus diluting the heat. Furthermore, grinding in motion can reach all corners of the solution, resulting in more thorough grinding. A filter section 5 and a filter adjustment section are provided. Before grinding is completed, the filter section 5 is sealed to prevent liquid leakage. After grinding, the filter adjustment section adjusts the filter section 5 to a filterable state, thereby filtering the solution. The unground carbon black aggregates filtered out remain at the top of the filter section 5 for reuse. An observation section is provided to monitor the reaction state inside the reactor 1 in real time, allowing operators to better control the reaction. A support leg 101 is provided at the bottom of the reactor 1 to ensure the stability of the reactor 1 during operation.

[0102] like Figures 1 to 3 As shown, the rotation drive unit includes: a motor connecting seat 302, which is disposed at the top of the reactor 1; a drive motor 301, which is disposed on the motor connecting seat 302; and a first rotating shaft 303, one end of which is connected to the drive motor 301 and the other end of which is connected to the stirring unit.

[0103] like Figures 3 to 6As shown, the stirring unit further includes: a stirring rod assembly 403, of which three sets are evenly fitted onto the rotating cylinder 402 to stir the liquid to be processed; a first through groove 406, which is formed on the side surface of the rotating cylinder 402; a first limiting slide rod 404, which is connected to the notch at the first through groove 406 formed on the rotating cylinder 402 to limit the movement of the driving unit; and a sealing plate 405, which is set on the first limiting slide rod 404 to ensure that the inside and outside of the rotating cylinder 402 are not connected.

[0104] In this embodiment of the invention, the drive motor 301 is started, driving the first rotating shaft 303 to rotate, which in turn drives the rotating cylinder 402 to rotate via the rotating block 401. The rotating cylinder 402 drives the stirring rod assembly 403 to rotate, thereby stirring the solution. The stirring rod assembly 403 is deflected upwards to allow the solution at the bottom to move to the top, thus improving the fluidity of the solution and ensuring a more complete reaction. A sealing plate 405 is provided to seal the inside and outside of the rotating cylinder 402. This prevents liquid from flowing into the rotating cylinder 402, causing contamination of parts and accumulation of reactants, which would hinder the complete reaction of the solution.

[0105] like Figures 5 to 8 As shown, the moving drive unit includes: a bidirectional lead screw 701, the top end of which is rotatably connected to the rotating block 401; an electromagnetic clutch 709, one end of which is connected to the bottom end of the bidirectional lead screw 701, and the other end of which is connected to the filter adjustment unit, the electromagnetic clutch 709 being used to control the rotation and stop of the bidirectional lead screw 701; a threaded ring sleeve 702, which is sleeved on the bidirectional lead screw 701; a second connecting shaft 703, one end of which is connected to the side of the threaded ring sleeve 702; and a square electromagnet 704, one end of which is connected to the other end of the second connecting shaft 703, and the other end of which is in contact with the sealing plate 405, the square electromagnet 704 sliding up and down within the first limiting slide bar 404.

[0106] like Figures 6 to 8 and Figure 12As shown, the moving drive unit further includes: a second dovetail slide bar 705, disposed on the outer surface of the sealing plate 405; a dovetail electromagnet 708, sliding within the second dovetail slide bar 705, fitting and connected to the sealing plate 405, and magnetically connected to the square electromagnet 704 across the sealing plate 405; a blocking support block 707, disposed at the bottom end of the second dovetail slide bar 705, to limit the movement of the dovetail electromagnet 708 to its lowest position; a first connecting shaft 601, fixedly connected to the dovetail electromagnet 708; a fixed rack 706, disposed on the sealing plate 405 and located outside the second dovetail slide bar 705; and a first gear 602, sleeved on the first connecting shaft 601 and meshing with the fixed rack 706.

[0107] In this embodiment of the invention, during the stirring process, the rotation of the rotating cylinder 402 drives the third connecting shaft 806 to rotate. The third connecting shaft 806 is connected to the bottom end of the electromagnetic clutch 709. At this time, the electromagnetic clutch 709 is activated, causing the bidirectional lead screw 701 to stop rotating, i.e., to rotate relative to the rotating cylinder 402. Under the limitation of the first limiting slide bar 404, the square electromagnet 704 and the second connecting shaft 703 can only follow the rotation of the rotating cylinder 402, thereby driving the threaded ring sleeve 702 to rotate relative to the bidirectional lead screw 701. This causes the threaded ring sleeve 702 to move up and down along the bidirectional lead screw 701. The threaded ring sleeve 702 simultaneously drives the second connecting shaft 703 and the square electromagnet. 704 moves up and down along the first limiting slide bar 404; at this time, the square electromagnet 704 and the dovetail electromagnet 708 are activated, causing them to attract each other. As the square electromagnet 704 moves up and down, it drives the dovetail electromagnet 708 to move up and down along the second dovetail slide bar 705. When the dovetail electromagnet 708 moves, it drives the first connecting shaft 601 and the first gear 602 to move up and down. Since the first gear 602 is meshed with the fixed rack 706, it will rotate simultaneously under the action of the fixed rack 706 during the up and down movement of the first gear 602. The rotating first gear 602 is connected to the grinding part 6 to help the grinding part 6 perform the grinding operation.

[0108] like Figures 8 to 9As shown, the grinding part 6 includes: a gear ring 603, sleeved on the first connecting shaft 601 and fixedly connected to the first gear 602 to rotate with the first gear 602; a planet carrier 604, sleeved on the first connecting shaft 601, with planet gears on the planet carrier 604 meshing with the gear ring 603; a sun gear 605, sleeved on the first connecting shaft 601 and meshing with the planet gears on the planet carrier 604; and a third rotating shaft 606, sleeved on the first connecting shaft 601 at the end away from the dovetail electromagnet 708 and fixedly connected to the sun gear 605 to rotate with the first gear 602. The sun gear 605 rotates; a hollow cylinder 608, one end of which is connected to the gear ring 603 to rotate with the gear ring 603, has a through groove to facilitate the entry and exit of the processing solution; several grinding balls 609 are provided inside the hollow cylinder 608 to move with the hollow cylinder 608 for collision grinding; a grinding rod 607 is provided inside the hollow cylinder 608, one end of which is connected to the third rotating shaft 606, and the other end is rotatably connected to the end of the hollow cylinder 608 away from the gear ring 603, and performs collision grinding with the grinding balls 609.

[0109] In this embodiment of the invention, when the dovetail electromagnet 708 moves up and down, it drives the first connecting shaft 601 and the gear ring 603, planet carrier 604, and sun gear 605 mounted on it to move up and down simultaneously. The first gear 602 is fixedly connected to the gear ring 603, so the rotation of the first gear 602 drives the gear ring 603 to rotate, and the rotation of the gear ring 603 drives the planet gears on the planet carrier 604 to rotate. Since the planet carrier 604 is fixed to the first connecting shaft 601, the axis of the planet gears is fixed, and they can only rotate around themselves, without generating a revolution around the sun gear 605. The rotation of the gear ring 603 drives the sun gear 605 to rotate. Due to the gear transmission relationship, the rotation directions of the gear ring 603 and the sun gear 605 are opposite. This makes the rotation direction of the hollow cylinder 608 driven by the gear ring 603 opposite to the rotation direction of the grinding rod 607 driven by the sun gear 605 via the third rotating shaft 606. This increases the intensity of the collision of the grinding balls 609 in the hollow cylinder 608 and improves the grinding efficiency. The design of the hollow cylinder 608 allows the solution to enter freely, ensuring that there is no situation where the solution cannot be ground, thus making the grinding more thorough.

[0110] like Figure 7 , Figures 10 to 12As shown, the filtration section 5 includes: a triangular support frame 510 disposed at the bottom of the reactor 1; a fixed support ring 508 disposed on the inner wall of the reactor 1; a second rotating shaft 509, one end of which is rotatably connected to the triangular support frame 510; a lower rotating disk 506 disposed on the fixed support ring 508 and sleeved on the second rotating shaft 509; three sets of second arc-shaped filter grooves 507, which are evenly distributed on the lower rotating disk 506; and an outer support ring 504 engaged with the inner wall of the reactor 1 and located in the groove at the upper end of the lower rotating disk 506. The inner support ring 503 is located in the upper groove of the lower rotating disk 506; the filter screen 505 is connected at one end to the outer support ring 504 and at the other end to the inner support ring 503, and is in close contact with the lower rotating disk 506; the upper rotating disk 501 is located on the outer support ring 504 and is fixedly connected to the bottom end of the rotating cylinder 402 so as to rotate with the rotating cylinder 402; three sets of first arc-shaped filter grooves 502 are provided, and the three sets of first arc-shaped filter grooves 502 are evenly opened on the upper rotating disk 501, and overlap or intersect with the second arc-shaped filter grooves 507.

[0111] like Figures 10 to 12 As shown, the filter adjustment unit includes: a third connecting shaft 806, fixedly connected to the upper rotating disk 501, and its top end connected to the electromagnetic clutch 709; a circular groove 807, formed at the bottom end of the third connecting shaft 806; a hexagonal groove 808, formed at the upper end of the circular groove 807; a second circular electromagnet 809, disposed at the upper end of the hexagonal groove 808; a limiting square groove 801, formed at the top end of the second rotating shaft 509; a spring 802, disposed within the limiting square groove 801, one end connected to the bottom end of the limiting square groove 801; an adjusting square rod 803, sliding within the limiting square groove 801, and its bottom end connected to the spring 802; a hexagonal prism 804, disposed at the top end of the adjusting square rod 803, and cooperating with the hexagonal groove 808; and a first circular electromagnet 805, disposed at the top end of the hexagonal prism 804, and cooperating with the second circular electromagnet 809.

[0112] In this embodiment of the invention, after grinding, the solution needs to be filtered. Before filtration, a three-layer structure consisting of an upper rotating disk 501, a filter screen 505, and a lower rotating disk 506 is provided to ensure a leak-proof seal during rotation. Specifically, an elastic waterproof structure is provided at the connection between the upper rotating disk 501 and the inner wall of the reactor 1 to prevent leakage at the connection point during rotation. Simultaneously, a rubber baffle is provided at the lower end of the first arc-shaped filter groove 502 where it contacts the filter screen 505 to prevent liquid from flowing from the gaps in the filter screen 505 to the second arc-shaped filter groove 507, which does not overlap with the first arc-shaped filter groove 502, and from seeping down through the second arc-shaped filter groove 507. Before filtration, the lower rotating disk 506 rotates simultaneously with the upper rotating disk 501, while the filter screen 505 is engaged with the inner wall of the reactor 1 to ensure relative stillness.

[0113] When filtration is required, the first circular electromagnet 805 and the second circular electromagnet 809 are activated, causing them to repel each other. This drives the hexagonal prism 804 downwards, disengaging it from the hexagonal slot 808, preventing the lower rotating disk 506 from following the upper rotating disk 501. At this point, the power to the first circular electromagnet 805 and the second circular electromagnet 809 is quickly turned off to eliminate the repulsive force. Then, under the action of the spring 802, the adjusting rod 803 and the hexagonal prism 804 move upwards. Due to the mismatched angles, the hexagonal prism 804 will abut against the opening of the hexagonal slot 808. After the hexagonal groove 808 rotates 60 degrees, it will reconnect with the hexagonal prism 804. The hexagonal prism 804 and the adjusting square rod 803 will drive the lower rotating disk 506 to rotate. At this time, the lower rotating disk 506 will have a 60-degree angle difference with the upper rotating disk 501, which will cause the first arc-shaped filter groove 502 and the second arc-shaped filter groove 507 to be on the same straight line. At this time, the first arc-shaped filter groove 502 and the second arc-shaped filter groove 507 are separated only by a filter screen 505, so that the solution after reaction and grinding will flow to the bottom of the reaction vessel 1 through the filter screen 505.

[0114] During the filtration process, the upper rotating disk 501 and the lower rotating disk 506 rotate simultaneously, so the positions of the first arc-shaped filter tank 502 and the second arc-shaped filter tank 507 are constantly rotating. This prevents the solution from flowing in the same direction during filtration, avoids competition for the outlet, and prevents polymerization effects. At the same time, the rotation of the first arc-shaped filter tank 502 scrapes the filter screen 505, which can simultaneously check for clogging and prevent blockage. Large carbon black particles that have not completed the reaction can also be carried by the first arc-shaped filter tank 502 into the solution above for grinding reaction. Even if the reactants are exhausted and cannot be reversed, they can remain in the reaction vessel 1 for further preparation and reaction.

[0115] like Figures 1 to 3As shown, the observation unit includes: a sight glass window 103, located at the top of the reactor 1, for observing the interior of the reactor 1; a sight glass lamp 104, located at the top of the reactor 1 and to one side of the sight glass window 103, for increasing the light inside the reactor 1; a temperature control unit 2 is provided on the outside of the reactor 1, the temperature control unit 2 including: a vessel body jacket 201, which wraps around the outside of the reactor 1; an electric heating tube 202, located inside the vessel body jacket 201, for heating the liquid inside the vessel body jacket 201; an inlet valve 203, located at the upper end of the vessel body jacket 201; and an outlet valve 204, located at the lower end of the vessel body jacket 201.

[0116] In this embodiment of the invention, before preparation, liquid is first introduced into the reactor jacket 201 through the inlet valve 203, and the electric heating tube 202 is activated to bring the reactor 1 to a suitable temperature. Then, the reactants are added into the reactor 1 through the feed valve 102. This ensures that the preparation process begins in a suitable temperature environment. Simultaneously, after the reaction, heat is generated, and the temperature inside the reactor 1 is detected by a temperature sensor to adjust the temperature of the liquid in the reactor jacket 201, ensuring that the preparation process remains in a suitable temperature environment throughout. The inclusion of a sight glass light 104 enhances the brightness inside the reactor 1, making it easier for operators to judge the reaction progress.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.

7. A method of using an anti-corrosion carbon black ink production and preparation equipment, applicable to the anti-corrosion carbon black ink production and preparation equipment as described in claim 6, characterized in that: Includes the following steps: S1. The liquid is introduced into the jacket (201) of the reactor body through the inlet valve (203), the electric heating tube (202) is activated to bring the reactor (1) to a suitable temperature, and the reactants are put into the reactor (1) through the feed valve (102); S2. Start the drive motor (301) to drive the first rotating shaft (303) to rotate. The first rotating shaft (303) drives the stirring assembly to rotate via the rotating block (401) and the rotating cylinder (402). The rotating cylinder (402) simultaneously drives the upper rotating disk (501) to rotate, thereby fully stirring the solution in the reactor (1). S3. While stirring, the third connecting shaft (806) rotates synchronously, activating the electromagnetic clutch (709), causing the double-acting lead screw (701) to stop rotating, thereby causing the threaded ring sleeve (702) to rotate relative to the double-acting lead screw (701), causing the threaded ring sleeve (702), the second connecting shaft (703), and the square electromagnet (704) to move up and down along the direction of the double-acting lead screw (701), activating the square electromagnet (704) and the dovetail electromagnet (708), causing them to attract each other, thereby causing the dovetail electromagnet (708) to move up and down along the second dovetail slide (705); the dovetail electromagnet (708) When it moves, it drives the first gear (602) to rotate along the fixed rack (706), which in turn drives the hollow cylinder (608) to rotate via the gear ring (603). At the same time, the gear ring (603) drives the sun gear (605) to rotate in the opposite direction via the planet carrier (604). Thus, the sun gear (605) drives the grinding rod (607) to rotate in the opposite direction to the rotation of the hollow cylinder (608), which in turn drives the grinding balls (609) to collide randomly, thereby grinding the solution. Because the grinding part (6) rotates with the rotating cylinder (402) and moves up and down at the same time, the heat generated by grinding will quickly move to all corners of the solution. S4. After grinding is completed, activate the first circular electromagnet (805) and the second circular electromagnet (809) to repel each other, thereby causing the hexagonal prism (804) to move downwards and disengage from the hexagonal slot (808), so that the lower rotating disk (506) no longer follows the upper rotating disk (501) in rotation. At this time, quickly turn off the power to the first circular electromagnet (805) and the second circular electromagnet (809) to eliminate the repulsive force. At this time, under the action of the spring (802), drive the adjusting rod (803) and the hexagonal prism (804) to move upwards. After the hexagonal slot (808) rotates 60 degrees, it will reconnect with the hexagonal prism (804), thereby driving the lower rotating disk (506) to rotate via the hexagonal prism (804) and the adjusting rod (803). When the lower rotating disk (506) is activated, a 60-degree angle difference is generated between the lower rotating disk (506) and the upper rotating disk (501), resulting in the first arc-shaped filter tank (502) and the second arc-shaped filter tank (507) being on the same straight line, separated only by a filter screen (505). This allows the solution after reaction and grinding to flow through the filter screen (505) to the bottom of the reactor (1). After filtration, the first circular electromagnet (805) and the second circular electromagnet (809) are activated again, resulting in a 60-degree angle difference between the lower rotating disk (506) and the upper rotating disk (501), thus causing the first arc-shaped filter tank (502) and the second arc-shaped filter tank (507) to be disconnected, forming a sealed state; preventing the unreacted and ground solution from flowing out. S5. Open the discharge valve (105) to discharge the filtered finished solution.
