Description

Technical Field

[0001] This invention relates to the field of electrolyte production, specifically to an acid-base neutralization reaction apparatus for producing electrolyte for aluminum electrolytic capacitors and its usage method. Background Technology

[0002] In the production process of electrolyte for aluminum electrolytic capacitors, the acid-base neutralization reaction is a critical process step. Upon contact, the acid and alkali solutions react violently immediately. As the raw material concentration increases, the reaction rate accelerates further, releasing a large amount of neutralization heat, which can easily lead to hazards. Under high-temperature conditions, scale easily forms on the inner wall of the reactor and near the feed inlet, causing material adhesion and accumulation, severely impacting production efficiency. In traditional equipment, during continuous operation, the scale gradually thickens, eventually clogging the feed pipe, forcing production interruptions for manual cleaning. This increases the risk of workers coming into contact with corrosive substances and may also damage the equipment's inner wall due to mechanical scraping. The precipitates generated by the acid-base reaction are difficult to disperse fully under conventional stirring conditions, easily forming a sediment layer at the bottom of the reactor. Existing stirrers mostly use a single rotation mode, which cannot effectively break up the precipitate agglomerates, leading to uneven mixing of the reactants. This not only reduces neutralization efficiency but may also cause side reactions due to excessively high local concentrations. The accumulation of reaction heat further exacerbates the crystallization problem, creating a vicious cycle that restricts the stability and consistency of the electrolyte product. Therefore, this paper proposes an acid-base neutralization reaction device for the production of electrolyte for aluminum electrolytic capacitors and its operating method. Summary of the Invention

[0003] The purpose of this invention is to provide an acid-base neutralization reaction apparatus and its method for producing electrolyte for aluminum electrolytic capacitors, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an acid-base neutralization reaction device for producing electrolyte for aluminum electrolytic capacitors, comprising a reaction vessel, an internal feed pipe connected to the reaction vessel, an anti-blocking component and a stirring component provided inside the reaction vessel, a straight cylinder fixedly connected inside the reaction vessel, and a box body fixedly connected inside the reaction vessel; The anti-clogging component includes a first motor, a gear, a flow sensor, and a controller. An annular rack that meshes with the gear is rotatably sleeved on the outer side of the feed pipe. A ring body is fixedly connected to the bottom of the annular rack, and two scrapers are fixedly connected to the upper surface of the ring body. The stirring assembly includes a second motor, a quadrangular prism, and a movable frame. A sleeve is fixedly inserted inside the movable frame, and a through groove adapted to the quadrangular prism is opened inside the sleeve. A slider is fixedly connected to the outside of the movable frame, and a spiral sine groove adapted to the slider is opened on the inner side wall of the straight cylinder.

[0005] Preferably, a bracket is fixedly connected to the bottom of the aforementioned box, and the flow sensor is fixedly installed on the upper surface of the bracket, with the flow sensor located directly below the feed pipe.

[0006] Preferably, the controller described above is installed on the top of the reactor, the flow sensor is electrically connected to the controller via a signal line, and the controller is electrically connected to the first motor via a power cable.

[0007] Preferably, the first motor is installed on the top of the reactor, and the gear is rotatably connected to the housing via a rotating shaft and connected to the output end of the first motor.

[0008] Preferably, the inner wall of the aforementioned annular rack is fixedly connected with an annular protrusion, and the outer side of the feed pipe is provided with an annular groove that matches the annular protrusion.

[0009] Preferably, a sealing ring is fixedly sleeved on the outer side of the aforementioned ring body, and a feed funnel is connected to the top of the feed pipe.

[0010] Preferably, a spiral spring tube is fixedly embedded between the aforementioned reaction vessel and the straight cylinder, and the top and bottom of the spiral spring tube are connected to conduits that penetrate the reaction vessel.

[0011] Preferably, the lower part of the straight cylinder is fixedly connected to a fixed frame, the second motor is installed on the top of the reactor, the output end of the second motor is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the top of the fixed frame through a bearing, the quadrangular prism is fixedly sleeved on the outside of the rotating shaft, and several stirring rollers are fixedly connected to the upper surface of the movable frame.

[0012] Preferably, the top of the aforementioned reactor is connected to a pipe, and the bottom of the reactor is connected to a discharge pipe.

[0013] In addition, the present invention also provides a method for using an acid-base neutralization reaction apparatus for the production of electrolyte for aluminum electrolytic capacitors, comprising the following steps: S1. Electrolyte reaction of capacitor: The electrolyte of aluminum electrolytic capacitor to be reacted is injected into the reaction vessel through the feed funnel, and the neutralizing agent is injected through the pipeline; S2, Electrolyte acid-base neutralization and stirring: The electrolyte of the aluminum electrolytic capacitor to be reacted is mixed with the neutralizing agent. The second motor drives the moving frame to rotate, and the stirring roller rotates accordingly to stir. At the same time, the slider slides in the spiral sine groove, so that the moving frame moves up and down back and forth during the rotation, increasing the stirring effect. S3. Removal of scale: High-pressure hot air makes it easy for scale to crystallize at the feed pipe. The first motor drives the scraper to rotate through the gear mechanism to scrape off the scale in the feed pipe and prevent it from sticking to the wall. S4. Heat dissipation from acid-base reaction: Because the acid-base reaction generates a large amount of heat after the electrolyte of the aluminum electrolytic capacitor is mixed with a neutralizing agent, the two ends of the spiral spring tube are connected to the external water pipe through conduits to continuously inject cold water for heat exchange, thereby reducing the heat inside the reactor.

[0014] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects: This invention effectively solves the technical problems existing in traditional acid-base neutralization reaction devices through innovative mechanical structure and automated control: The anti-clogging component adopts a linkage design of real-time monitoring by a flow sensor and automatic scraping. When an abnormal feed flow is detected, the controller immediately starts the motor to drive the scraper to rotate and remove the crystallized scale, avoiding the safety hazards and equipment damage of manual cleaning and ensuring the continuity of production. The stirring assembly uses a unique sinusoidal groove and square prism combination structure to enable the stirring roller to move up and down while rotating, forming a three-dimensional stirring effect, which completely breaks up sedimentation and agglomeration, ensures uniform mixing of reactants, and significantly improves neutralization efficiency and product consistency. The spiral spring tube cooling system, combined with circulating cold water through conduits, efficiently removes the neutralization heat generated during the reaction, precisely controls the reaction temperature, and prevents local overheating that could exacerbate crystallization, thus fundamentally solving the vicious cycle problem caused by heat accumulation. Through the synergistic effect of mechanical optimization and intelligent control, the entire system achieves safe, efficient, and stable operation in the production of electrolyte for aluminum electrolytic capacitors.

Example 1

[0020] Please see Figure 1-9 This invention provides a technical solution: an acid-base neutralization reaction device for producing electrolyte for aluminum electrolytic capacitors, comprising a reaction vessel 1, an inlet pipe 3 connected to the inside of the reaction vessel 1, an anti-blocking component 5 and a stirring component 6 provided inside the reaction vessel 1, a straight cylinder 11 fixedly connected inside the reaction vessel 1, a box body 10 fixedly connected inside the reaction vessel 1, a pipe 4 connected to the top of the reaction vessel 1, and a discharge pipe 9 connected to the bottom of the reaction vessel 1. The neutralizing agent is injected into the reaction vessel 1 through the pipe 4, and the liquid after the reaction is completed is discharged through the discharge pipe 9. A feed funnel 2 is connected to the top of the inlet pipe 3, and the aluminum electrolytic capacitor electrolyte to be reacted is injected into the connected inlet pipe 3 through the feed funnel 2.

[0021] The anti-clogging component 5 includes a first motor 51, a gear 52, a flow sensor 59, and a controller 510. An annular rack 53, meshing with the gear 52, is rotatably sleeved on the outer side of the feed pipe 3. A ring body 56 is fixedly connected to the bottom of the annular rack 53. Two scrapers 57 are fixedly connected to the upper surface of the ring body 56. A sealing ring 511 is fixedly sleeved on the outer side of the ring body 56, providing a seal to the housing 10 when the ring body 56 rotates. An annular protrusion 54 is fixedly connected to the inner wall of the annular rack 53. An annular groove 55, matching the annular protrusion 54, is provided on the outer side of the feed pipe 3, increasing the stability of the annular rack 53's rotation. The first motor 51 is installed on the top of the reactor 1. The gear 52 is rotatably connected to the housing 10 via a rotating shaft and connected to the output end of the first motor 51. The first motor 51 drives the gear 52 to rotate. A bracket 58 is fixedly connected to the bottom of the reactor 1. A flow sensor 59 is fixedly installed on the upper surface of the bracket 58. The flow sensor 59 is located directly below the feed pipe 3. The bracket 58 supports the flow sensor 59. The controller 510 is installed on the top of the reactor 1. The flow sensor 59 and the controller 510 are electrically connected through a signal line. The controller 510 is electrically connected to the first motor 51 through a power cable. When the lower part of the feed pipe 3 is covered with scale, the feed flow rate of the feed pipe 3 decreases. When the flow rate is continuously lower than the threshold set by the flow sensor 59 for more than 10 seconds, the flow sensor 59 drives the first motor 51 to rotate 50-60 times through the controller 510. The gear 52 drives the meshing ring rack 53 to rotate, thereby driving the scraper 57 to rotate and scrape the lower inner wall of the feed pipe 3 to prevent it from sticking to the wall.

[0022] The workflow and principle are as follows: The electrolyte for aluminum electrolytic capacitors enters the feed pipe 3 through the feed funnel 2, while the neutralizing agent is injected into the reaction vessel 1 through the pipe 4. A flow sensor 59 monitors the feed flow rate in real time. When the flow rate is detected to be below a set threshold for 10 seconds, the controller 510 immediately starts the first motor 51, which operates at a fixed speed of 50-60 revolutions. The controller 510 controls the number of rotations of the first motor 51 through a preset program, using an encoder to detect the actual number of revolutions. The motor automatically stops once the set value is reached. The first motor 51 drives the ring rack 53 to rotate via gear 52, causing the scraper 57 on the ring 56 to scrape and clean the inner wall of the feed pipe 3. The scraper 57 has an extended design, extending 4cm-6cm above and below the height of the feed pipe 3, covering the entire inner wall of the feed pipe 3. This automatic anti-clogging process avoids the safety hazards associated with manual cleaning. The entire process achieves safe and continuous production of the acid-base neutralization reaction through mechanical linkage and sensor feedback. Example 2

[0023] The stirring assembly 6 includes a second motor 65, a quadrangular prism 63, and a movable frame 61. A sleeve 62 is fixedly inserted inside the movable frame 61. The sleeve 62 has a through groove 64 that matches the quadrangular prism 63. A slider 68 is fixedly connected to the outside of the movable frame 61. A spiral sine groove 67 that matches the slider 68 is opened on the inner side wall of the straight cylinder 11. A fixed frame 7 is fixedly connected to the lower part of the straight cylinder 11. The second motor 65 is installed on the top of the reactor 1. A rotating shaft is fixedly connected to the output end of the second motor 65. The rotating shaft is rotatably connected to the top of the fixed frame 7 through a bearing. The quadrangular prism 63 is fixedly sleeved on the outside of the rotating shaft. Several stirring rollers 66 are fixedly connected to the upper surface of the movable frame 61. The second motor 65 drives the quadrangular prism 63 to rotate, thereby driving the movable frame 61 to rotate, and the stirring rollers 66 stir accordingly.

[0024] Working Process and Principle: After the second motor 65 starts, it drives the rotating shaft to rotate, causing the quadrangular prism 63 to rotate within the through groove 64 of the sleeve 62. Since the slider 68 of the moving frame 61 is constrained by the spiral sinusoidal groove 67 of the straight cylinder 11, the rotational motion of the quadrangular prism 63 is converted into the spiral lifting motion of the moving frame 61. The fixedly connected stirring roller 66 rotates simultaneously and performs up-and-down reciprocating motion, forming a three-dimensional stirring trajectory. This composite motion ensures thorough mixing of the electrolyte and neutralizing agent within the straight cylinder 11, effectively preventing sedimentation and accumulation. The spiral sinusoidal groove 67 is a spiral-shaped three-dimensional spatial curve. The entire stirring process achieves dual motion through a single power source of the second motor 65, resulting in a compact structure and high stirring efficiency. The flow sensor 59 is a BL-SLL-HZ06FB manufactured by Dongguan Bailing Electronics Co., Ltd., and both the first motor 51 and the second motor 65 are CLJSJ-CH02 manufactured by Kunshan Taiya Electromechanical Technology Co., Ltd. Since the structure and operating principle of these models are existing technologies, their structure and operating principle will not be described in detail here. Example 3

[0025] A spiral spring tube 8 is fixedly embedded between the reactor 1 and the straight cylinder 11. The top and bottom of the spiral spring tube 8 are connected to a conduit 12 that passes through the reactor 1. Cold water is continuously injected into the spiral spring tube 8 through the conduit 12 to reduce the temperature inside the reactor 1.

[0026] Working process and principle: Cold water is continuously injected into the spiral spring tube 8 through conduit 12, forming a spiral flow channel in the annular space between the reactor 1 and the straight cylinder 11. Cooling water flows along the spiral path of the spiral spring tube 8, fully absorbing the neutralization heat generated by the reaction. Cold water is injected from the lower conduit 12, flows in the opposite direction through the spiral spring tube 8, and then high-temperature cooling water is discharged from the upper conduit 12, while low-temperature cooling water is replenished from the lower conduit 12, forming a circulating cooling system. The spiral structure of the spiral spring tube 8 increases the heat exchange area, and combined with the forced convection of the stirring assembly 6, it effectively controls the reaction temperature and prevents local overheating that could lead to accelerated crystallization.

[0027] In addition, the present invention also provides a method for using an acid-base neutralization reaction apparatus for the production of electrolyte for aluminum electrolytic capacitors, comprising the following steps: S1. Electrolyte reaction of capacitor: The electrolyte of aluminum electrolytic capacitor to be reacted is injected into the reaction vessel 1 through the feed funnel 2, and the neutralizing agent is injected through the pipe 4. S2, Electrolyte acid-base neutralization and stirring: The electrolyte of the aluminum electrolytic capacitor to be reacted is mixed with the neutralizing agent. The second motor 65 drives the moving frame 61 to rotate, and the stirring roller 66 rotates and stirs accordingly. At the same time, the slider 68 slides in the spiral sine groove 67, so that the moving frame 61 moves up and down back and forth during the rotation, increasing the stirring effect. S3. Removal of scale: High-pressure hot air makes it easy for scale to crystallize at the feed pipe 3. The first motor 51 drives the scraper 57 to rotate through the gear mechanism to scrape off the inner wall of the feed pipe 3 and prevent it from sticking to the wall. S4. Heat dissipation from acid-base reaction: Because the acid-base reaction generates a large amount of heat after the electrolyte of the aluminum electrolytic capacitor is mixed with a neutralizing agent, the two ends of the spiral spring tube 8 are connected to the external water pipe through the conduit 12 to continuously inject cold water for heat exchange, thereby reducing the heat in the reaction vessel 1.

[0028] In summary, the electrolyte enters through the feed funnel 2, the neutralizing agent is injected through the pipe 4, and the flow sensor 59 monitors the flow rate in real time. When a blockage is detected, the controller 510 starts the first motor 51 to drive the scraper 57 to automatically clean the scale, ensuring smooth feeding. The stirring assembly 6 adopts an innovative composite motion design. The second motor 65, through the cooperation of the quadrangular prism 63 and the spiral sine groove 67, enables the stirring roller 66 to simultaneously rotate and reciprocate up and down, forming a three-dimensional stirring trajectory, effectively preventing sediment accumulation and improving mixing efficiency. The cooling system achieves efficient heat exchange through the spiral spring tube 8. The cooling water circulates along the spiral path, and in conjunction with the forced convection generated by stirring, it quickly removes the heat of neutralization reaction, accurately controls the reaction temperature, avoids local overheating and crystallization, and ensures safe and stable production operation.
