Description

Technical Field

[0001] This invention relates to the field of resin material production technology, specifically to a defoaming device for the production of phenolic resin lithium battery negative electrode carbon material. Background Technology

[0002] In the production of carbon materials for lithium-ion batteries using phenolic resin, efficient foam removal is crucial for ensuring production continuity, product consistency, and performance stability. Existing chemical defoaming methods are limited by the introduction of impurities, while traditional mechanical defoaming equipment suffers from low efficiency and poor adaptability. Therefore, there is an urgent need for a specialized device that is additive-free, highly adaptable, and capable of efficiently defoaming high-viscosity phenolic resin systems.

[0003] Patent publication number CN216170138U relates to a defoaming device for chemical resin production, belonging to the field of resin production technology. This defoaming device for chemical resin production includes a housing, a defoaming mechanism, and auxiliary components. The bottom of the housing has an opening, within which a discharge hopper is fixedly installed. The defoaming mechanism includes a support plate, a cylinder, a first air guide pipe, a foam suction plate, a second air guide pipe, and a foam suction machine. The auxiliary components include a stirring mechanism and a moving mechanism, with the stirring mechanism located below the moving mechanism. This defoaming device for chemical resin production, through the coordinated use of its components, thoroughly stirs the resin, expelling air from within the resin and puncturing some foam, thus removing foam from the stirred resin. The generated foam is then sucked up and collected, replacing traditional manual defoaming methods, improving defoaming efficiency, reducing worker workload, and featuring a simple structure, ease of use, and strong practicality.

[0004] The aforementioned patents improve defoaming efficiency, reduce worker workload, have simple structures, are easy to use, and are highly practical. However, if the subsequent defoaming device only treats the already formed foam without blocking the source of its generation, the foam generation rate will exceed the elimination rate and increase overall energy consumption. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a defoaming device for the production of phenolic resin lithium battery negative electrode carbon materials, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a defoaming device for the production of phenolic resin lithium battery negative electrode carbon materials, comprising a tank and a feeding cylinder. The feeding cylinder is located at the top of the tank, and a servo motor is installed at the bottom of the tank. A rotating rod is fixedly installed at the output end of the servo motor, and a spiral blade is fixedly installed on the circumferential surface of the rotating rod. A shearing device is installed inside the tank, comprising a buffer plate, a diverting plate, a guide plate, a rack ring, a connecting rod, a gear, a drive rod, a saw blade, and a stirring blade. The buffer plate is fixedly installed on the inner wall of the feeding cylinder, and the diverting plate is fixedly installed on the inner wall of the tank. The guide plate is fixedly installed on the inner wall of the tank, the rack ring is fixedly installed on the inner wall of the tank, the connecting rod is fixedly installed on the circumferential surface of the rotating rod, the gear is rotatably installed at the bottom of the connecting rod, the drive rod is fixedly installed at the bottom of the gear, the sawtooth blade is fixedly installed on the surface of the drive rod, and the stirring blade is fixedly installed on the surface of the drive rod. By adding resin from the feed cylinder, the resin will come into contact with multiple buffer plates, which can disperse the resin into multiple fine streams. Then it flows through the diverter plate, and is diverted again by the diverter plate, so that the resin continues to flow as fine streams to the surface of the guide plate. Then, the resin drips onto both sides of the inner wall of the tank and collects through the guide plate.

[0007] According to the above technical solution, the surface of the tank is provided with a discharge port, the circumferential surface of the discharge port is provided with a valve, the rack ring meshes with the gear, and the movement of the gear will contact the rack ring, causing the gear to rotate;

[0008] The surface of the tank is equipped with an addition device for adding chemicals when the foam thickness exceeds a set value and a cleaning device for removing residual resin from the inner wall of the outlet.

[0009] According to the above technical solution, the adding device includes an observation window and an ultrasonic sensor. The observation window is set on the surface of the tank, and a liquid level mark is set on the surface of the observation window. The ultrasonic sensor is set on the surface of the tank. During the resin adding process, the liquid level is observed through the observation window to ensure that the liquid level does not exceed the liquid level mark. The height of the foam is detected in real time by the ultrasonic sensor.

[0010] According to the above technical solution, the adding device further includes a defoamer tank, a dosing port, and a solenoid valve. The defoamer tank is fixedly installed on the circumferential surface of the tank body. The dosing port is located between the defoamer tank and the tank body. The solenoid valve is located on the surface of the dosing port. The solenoid valve is electrically connected to an ultrasonic sensor. When the height exceeds a set value, a command is triggered to open the solenoid valve. At this time, the defoamer inside the defoamer tank enters the tank body through the dosing port.

[0011] According to the above technical solution, the adding device also includes a second servo motor and a round rod. The fixed end of the second servo motor is fixedly installed on the surface of the tank, and the round rod is fixedly installed on the output end of the second servo motor. The surface of the round rod is provided with a first reciprocating spiral groove and a second reciprocating spiral groove, so that the triangular rod moves up and down along the first reciprocating spiral groove, while the drive frame moves up and down along the second reciprocating spiral groove.

[0012] According to the above technical solution, the adding device further includes a triangular rod, a guiding rod, and a drive frame. The triangular rod is threaded on the circumferential surface of the round rod, the guiding rod is fixedly installed on the circumferential surface of the round rod, and the drive frame is threaded on the circumferential surface of the round rod, so that the rotation of the guiding rod generates shearing force and the up-and-down agitation of the triangular rod.

[0013] According to the above technical solution, the cleaning device includes a fixed frame and a pressing rod. The fixed frame is fixedly installed on the circumferential surface of the discharge port, and the pressing rod is rotatably installed on the inner wall of the fixed frame. A torsion spring is provided between the pressing rod and the fixed frame, and the pressing rod is reset by the torsion spring.

[0014] According to the above technical solution, the cleaning device also includes a rotating rod and a servo motor. The rotating rod is rotatably mounted on the inner wall of the fixed frame. A second torsion spring is provided between the rotating rod and the fixed frame. The rotating rod is reset by the second torsion spring. The fixed end of the servo motor is fixedly mounted on the surface of the rotating rod.

[0015] According to the above technical solution, the cleaning device further includes a rotating frame, a rubber plate, and a limiting block. The rotating frame is fixedly installed at the output end of the servo motor, the rubber plate is fixedly installed on the surface of the rotating frame, and the limiting block is fixedly installed on the surface of the rotating frame, so that the rubber plate can remove the scale layer, so that the thin scale layer that has just formed on the inner wall can be peeled off in time, and the scale layer can be prevented from continuously thickening, which would cause the inner diameter of the discharge port to shrink or be partially blocked.

[0016] This invention provides a defoaming device for the production of phenolic resin lithium battery negative electrode carbon materials. It has the following beneficial effects:

[0017] (1) In this invention, by setting up a defoaming device, the resin is added from the feed cylinder, and the resin flows in a thin stream to the surface of the guide plate through the buffer plate and the diverter plate. Then, the resin drips to both sides of the inner wall of the tank and converges in the center through the guide plate. If the initial amount of foam is too large, the subsequent equipment needs to run for a longer time or at a higher power. By reducing the generation of foam from the source, the overall energy consumption of the equipment is reduced. The rotation of the spiral blade makes the bubbles move upward under the action of buoyancy and the spiral blade rotates in the same direction, which accelerates the migration of bubbles from the inside of the resin to the liquid surface. At the same time, the saw blade is sheared by the revolution and rotation of the saw blade. The revolution trajectory is designed to be close to the spiral blade and the inner wall of the tank, so that the saw blade can sweep through the gaps and grooves of the spiral blade, avoiding the accumulation of bubbles in dead corners. The rotation makes the saw blade contact the resin stuck in the dead corners of the tank while it is revolutionizing, ensuring that the defoaming is thorough.

[0018] (2) In this invention, by setting up an addition device, the liquid level is observed through an observation window during the resin addition process, so that the liquid level does not exceed the liquid level mark. The height of the foam is detected in real time by an ultrasonic sensor. When the height exceeds the set height, an instruction is triggered to open the solenoid valve. At this time, the defoamer inside the defoamer tank enters the tank through the dosing port, which prevents gas molecules from entering the liquid to form new bubbles and inhibits the existence of new bubbles. At the same time, the energy consumption of the shearing device is reduced. In the defoamer tank, the upper light component and the lower heavy component of the defoamer are mixed by the rotational shearing force of the triangular rod and the guide rod and the up and down stirring of the triangular rod, so as to avoid obvious density stratification and ensure that the concentration of the effective component of the defoamer is consistent.

[0019] (3) In this invention, the initial state of the cleaning device is the storage state. After the resin defoaming is completed, the resin is allowed to flow out from the outlet by opening the valve. The residual resin will gradually come into contact with the air and solidify to form a hard solid scale layer, which will cause the inner diameter of the outlet to become smaller or even cause local blockage, resulting in a decrease in the discharge flow rate and unstable flow rate. The scale layer is removed by the rubber plate, so that the thin scale layer that has just formed on the inner wall can be peeled off in time, preventing the scale layer from continuing to thicken and causing the inner diameter of the outlet to shrink or local blockage, ensuring that the resin flows out with a uniform flow rate and stable flow rate. When storage is required, the storage operation can be performed by moving the limiting block to the pressed rod to re-limit it. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-7One embodiment of the present invention is: a defoaming device for producing phenolic resin lithium battery negative electrode carbon material, comprising a tank body 1 and a feeding cylinder 2. The feeding cylinder 2 is located at the top of the tank body 1. A servo motor 3 is installed at the bottom of the tank body 1. A rotating rod 4 is fixedly installed at the output end of the servo motor 3. A spiral blade 5 is fixedly installed on the circumferential surface of the rotating rod 4. A shearing device is installed inside the tank body 1. The shearing device includes a buffer plate 10, a diverting plate 11, a guide plate 12, a rack ring 13, a connecting rod 14, a gear 15, a drive rod 16, a saw blade 17, and a stirring blade 18. The buffer plate 10 is fixedly installed on the inner wall of the feeding cylinder 2, and the diverting plate 11 is fixedly installed on the bottom of the tank body 1. The inner wall, the guide plate 12 is fixedly installed on the inner wall of the tank 1, the rack ring 13 is fixedly installed on the inner wall of the tank 1, the connecting rod 14 is fixedly installed on the circumferential surface of the rotating rod 4, the gear 15 is rotatably installed on the bottom of the connecting rod 14, the drive rod 16 is fixedly installed on the bottom of the gear 15, the saw blade 17 is fixedly installed on the surface of the drive rod 16, and the stirring blade 18 is fixedly installed on the surface of the drive rod 16. The revolution trajectory is designed to be close to the spiral blade 5 and the inner wall of the tank 1, so that the saw blade 17 can sweep through the gaps, grooves and other parts of the spiral blade 5, avoiding the accumulation of bubbles in dead corners. The rotation makes the saw blade 17 contact the resin retained in the dead corners of the tank 1 while revolving, ensuring that defoaming is not missed.

[0030] The surface of the tank body 1 is provided with a discharge port 6, and a valve 7 is provided on the circumference of the discharge port 6. The rack ring 13 meshes with the gear 15.

[0031] In this embodiment, during operation: Resin is added from the feed cylinder 2, and it comes into contact with multiple buffer plates 10, dispersing it into multiple fine streams. These streams then flow through the diverter plate 11, where they are further divided, causing the resin to continue flowing as fine streams to the surface of the guide plate 12. The guide plate 12 then causes the resin to drip onto both sides of the inner wall of the tank 1 for collection. If the initial foam volume is too large, subsequent equipment operation will require longer periods or higher power. Reducing foam at the source lowers the overall energy consumption of the equipment. At this time, the output of the servo motor 3 drives the rotating rod 4 to rotate, which in turn drives the spiral blade 5 to rotate. The rotation of the spiral blade 5 causes the bubbles to move upwards under buoyancy, aligning with the direction of the spiral blade 5, thus accelerating the bubbles from the resin. As the internal structure migrates towards the liquid surface, the rotating rod 4 rotates, simultaneously driving the connecting rod 14 to rotate. The rotation of the connecting rod 14 then drives the gear 15 to move. The moving gear 15 comes into contact with the rack ring 13, causing the gear 15 to rotate. The rotation of the gear 15 then drives the drive rod 16 to rotate, which in turn drives the saw blade 17 to rotate. Simultaneously, it drives the stirring blade 18 to rotate, causing it to revolve around the rotating rod 4 while also rotating on its own axis. When the bubbles reach the liquid surface, they are sheared by the saw blade 17. The orbital trajectory is designed to be close to the spiral blade 5 and the inner wall of the tank 1, allowing the saw blade 17 to sweep over the gaps and grooves of the spiral blade 5, preventing bubbles from accumulating in dead corners. The rotation on its own axis allows the saw blade 17 to contact the resin retained in the dead corners of the tank 1 while revolving, ensuring that defoaming is thorough.

[0032] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the surface of the tank 1 is provided with an adding device for adding a chemical agent when the foam thickness exceeds a set value and a cleaning device for removing residual resin on the inner wall of the outlet 6. The adding device includes an observation window 20 and an ultrasonic sensor 21. The observation window 20 is provided on the surface of the tank 1 and a liquid level mark is provided on the surface of the observation window 20. The ultrasonic sensor 21 is provided on the surface of the tank 1 for real-time monitoring of the foam height.

[0033] The addition device also includes a defoamer tank 22, a dosing port 23, and a solenoid valve 24. The defoamer tank 22 is fixedly installed on the circumferential surface of the tank body 1. The dosing port 23 is located between the defoamer tank 22 and the tank body 1. The solenoid valve 24 is located on the surface of the dosing port 23. The solenoid valve 24 is electrically connected to the ultrasonic sensor 21. When the foam is high, the addition device is activated to reduce the energy consumption of the shearing device.

[0034] The adding device also includes a second servo motor 25 and a round rod 26. The fixed end of the second servo motor 25 is fixedly installed on the surface of the tank 1, and the round rod 26 is fixedly installed on the output end of the second servo motor 25. The surface of the round rod 26 is provided with a first reciprocating spiral groove and a second reciprocating spiral groove.

[0035] The addition device also includes a triangular rod 27, a guiding rod 28, and a drive frame 29. The triangular rod 27 is threaded onto the circumferential surface of the round rod 26, the guiding rod 28 is fixedly installed on the circumferential surface of the round rod 26, and the drive frame 29 is threaded onto the circumferential surface of the round rod 26. Through the rotational shearing force of the guiding rod 28 and the up-and-down stirring of the triangular rod 27, the upper light component of the defoamer is mixed with the lower heavy component, avoiding obvious density stratification and ensuring that the concentration of the effective component of the defoamer is consistent.

[0036] The cleaning device includes a fixed frame 30 and a pressing rod 31. The fixed frame 30 is fixedly installed on the circumferential surface of the discharge port 6, and the pressing rod 31 is rotatably installed on the inner wall of the fixed frame 30. A torsion spring is provided between the pressing rod 31 and the fixed frame 30.

[0037] The cleaning device also includes a rotating rod 32 and a servo motor 33. The rotating rod 32 is rotatably mounted on the inner wall of the fixed frame 30. A second torsion spring is provided between the rotating rod 32 and the fixed frame 30. The fixed end of the servo motor 33 is fixedly mounted on the surface of the rotating rod 32.

[0038] The cleaning device also includes a rotating frame 34, a rubber plate 35, and a limiting block 36. The rotating frame 34 is fixedly installed at the output end of the servo motor 33, the rubber plate 35 is fixedly installed on the surface of the rotating frame 34, and the limiting block 36 is fixedly installed on the surface of the rotating frame 34. The device removes the scale layer, so that the thin scale layer that has just formed on the inner wall can be peeled off in time, preventing the scale layer from continuing to thicken and causing the inner diameter of the outlet 6 to shrink or become partially blocked, thus ensuring that the resin flows out at a uniform flow rate and with a stable flow rate.

[0039] In this embodiment, during resin addition, the liquid level is observed through the observation window 20 to ensure it does not exceed the level mark. The height of the foam is monitored in real time by the ultrasonic sensor 21. When the foam exceeds a set height, a command is triggered, causing the solenoid valve 24 to open. At this time, the defoamer inside the defoamer tank 22 enters the tank 1 through the dosing port 23, preventing gas molecules from entering the liquid and forming new bubbles, thus suppressing the existence of new bubbles and reducing the energy consumption of the shearing device. Within the defoamer tank 22, the output of the servo motor 25... The rotation of the end drives the round rod 26 to rotate. When the round rod 26 rotates, it drives the reciprocating spiral groove one and the reciprocating spiral groove two to rotate simultaneously, so that the triangular rod 27 moves up and down along the reciprocating spiral groove one, while the drive frame 29 moves up and down along the reciprocating spiral groove two. At the same time, the rotation of the round rod 26 drives the guide rod 28 to rotate. Through the rotational shearing force of the guide rod 28 and the up and down stirring of the triangular rod 27, the upper light component and the lower heavy component of the defoamer are mixed to avoid obvious density stratification and ensure that the concentration of the effective component of the defoamer is consistent.

[0040] The initial state of the cleaning device is the retracted state, i.e., the second torsion spring is in the stretched state, and the limiting block 36 is restricted by the pressing rod 31. After the resin defoaming is completed, the resin flows out of the outlet 6 by opening the valve 7. The residual resin will gradually come into contact with the air and solidify, forming a hard solid scale layer, which will cause the inner diameter of the outlet 6 to become smaller, or even cause partial blockage, resulting in a decrease in the discharge flow rate and unstable flow. At this time, the drive frame 29 moves downward and contacts one side of the pressing rod 31. Through the lever principle, the other side rotates upward. When it rotates upward, it disengages from the limiting block 36. At this time, the second torsion spring is released, causing the rotating rod 32 to reset. The movement of the rotating rod 32 drives the servo motor 33. The servo motor 33 moves, driving the rotating frame 34 to move. The rotating frame 34 moves, driving the rubber plate 35 to move until the rubber plate 35 contacts the inner wall of the outlet 6, at which point it is fully reset. Then, the output of the servo motor 33 drives the rotating frame 34 to rotate. The rotation of the rotating frame 34 drives the rubber plate 35 to rotate along the inner wall of the outlet 6, so that the rubber plate 35 removes the scale layer, so as to peel off the thin scale layer that has just formed on the inner wall in time, preventing the scale layer from continuing to thicken and causing the inner diameter of the outlet 6 to shrink or become partially blocked. This ensures that the resin flows out at a uniform flow rate and with a stable flow rate. When it is necessary to store the resin, the storage operation can be performed by moving the limiting block 36 to be repositioned by the pressing rod 31.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
