Description

Technical Field

[0001] This utility model relates to the field of electronic chemical production technology, specifically to a high-efficiency dissolution reaction device for preparing special exchange membranes. Background Technology

[0002] With the rapid development of high-tech industries, the chip semiconductor industry and new energy battery industry generate a large number of impurity particles during the wafer packaging process. These particles dissolve in the packaging liquid, affecting the performance of the packaged product. This places extremely high demands on the production process of proton exchange membranes, especially the dissolution reaction equipment. The preparation of proton exchange membranes requires a dissolution reaction, during which viscosity increases, necessitating very precise control of stirring and temperature. Simultaneously, it is crucial to ensure product purity and prevent contact with the external environment. Existing dissolution equipment primarily relies on ordinary stirring reactions, operating at room temperature without suitable heating or cooling systems, thus impacting the preparation efficiency of related products. Traditional dissolution reaction equipment mostly uses a stirrer within the dissolution reactor, directly adding the medium for dissolution. This results in a long preparation cycle, the medium's volatility at high temperatures affecting purity and quality, and the low degree of isolation between the dissolution reaction equipment and the atmosphere, leading to low product purity and impacting product quality.

[0013] Furthermore, the agitator includes: a frame agitator, a linear agitator, and a finned agitator, wherein the linear agitator and the finned agitator are installed inside the frame agitator.

[0018] The advantage of adopting the above technical solution is that the temperature sensor is used to sense the reaction temperature and is connected to the dissolution reaction control device to realize closed-loop control of the reaction temperature and improve the dissolution efficiency.

[0019] Furthermore, the jacket cavity receives a heat medium or a cooling medium from the feed inlet and discharges it from the jacket medium outlet.

[0020] The advantage of adopting the above technical solution is that when the reaction begins in the reaction vessel, a heat medium is introduced into the jacketed cavity to ensure the reaction heat in the inner cavity, so that the internal substances can react fully. After the reaction is completed, a cooling substance is introduced to cool down the internal medium, so that the internal medium temperature is reduced and it is convenient to discharge, effectively improving the reaction efficiency.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figure 1 As shown, this utility model discloses a high-efficiency dissolution reaction apparatus for preparing special exchange membranes, comprising:

[0030] The reaction vessel 1 has an internal jacket, including an inner cavity 11 and a jacketed cavity 12. The inner cavity 11 and the jacketed cavity 12 are respectively provided with a feed inlet 13 and a feed inlet 14. The bottom of the reaction vessel 1 is provided with a jacketed medium output port 121 connected to the jacketed cavity 12 and a liquid discharge port 111 connected to the inner cavity 11.

[0031] The stirring device includes a plurality of stirrers disposed in the inner cavity 11, the stirrers being driven by a stirring shaft 2 passing through the reaction vessel 1;

[0032] Dissolution reaction control device 4 is used to control the reaction temperature and stirring time.

[0033] The advantages of adopting the above technical solution are that it improves the efficiency of the dissolution reaction, improves the purity of the product, is applicable to various scenarios and can prepare various specifications, greatly improves production efficiency, and can be applied to the dissolution reaction process in the preparation of various electronic-grade membrane products.

[0034] In some implementations, the bottom of the reaction vessel 1 is conical, and the entire reaction vessel 1 is supported and fixed by a support frame. Both the inner cavity 11 and the jacket cavity 12 are conical to facilitate material discharge. The jacket medium outlet 121 and the liquid outlet 111 are set with conical bottoms. A compressed air distributor 15 is set on the upper side of the reaction vessel 1, which is connected to the inner cavity 11 to control the compressed air flow. After processing, a large amount of compressed gas is introduced into the reaction vessel 1 to discharge the viscous product inside from the liquid outlet 111. The conical bottom design ensures that there is no residue in the reaction vessel 1 and facilitates cleaning.

[0035] Furthermore, ultrasonic probes 3 are symmetrically arranged on the sidewalls of the inner cavity 11. The ultrasonic frequency and power are adjusted by an ultrasonic generator, and the opening and closing of the ultrasonic generator are also controlled by the dissolution reaction control device 4. The ultrasonic probes 3 emit ultrasonic waves, which can control the reaction temperature and dissolution reaction contact area in coordination with the jacket by adjusting different ultrasonic frequencies and ultrasonic power; and can also thoroughly clean the dissolution reaction tank 1 according to the state after the reaction.

[0036] The dissolution reaction control device 4 can be composed of a computer and a controller, which receives temperature signals, controls the operation of the ultrasonic probe 3 and the stirring device, and can also control the opening and closing of the feed inlet and the valve for discharging, and control the working status of the compressed air distributor 15 to realize the control of the entire system. This control method and control principle belong to the existing technology.

[0037] In some embodiments, the stirrer includes: a frame stirrer 5, a linear stirrer 51, and a finned stirrer 52. The linear stirrer 51 and the finned stirrer 52 are installed inside the frame stirrer 5, and the finned stirrer 52 is located above the linear stirrer 51. Both are connected to the stirring shaft 2. A stirring controller 21 is provided on the upper side of the stirring shaft 2 for driving and controlling the stirring rate and stirring direction. There are two frame stirrers 5, with the larger frame stirrer 5 fitted outside the smaller frame stirrer 5. The arrangement of two frame stirrers improves the stirring capacity and can form a larger stirring turbulence, thereby increasing the dissolution reaction rate. The finned stirrer 52 has multiple arc-shaped stirring blades, which form a small turbulence on the upper side. The linear stirrer 51 includes multiple straight stirring blades, which enhance the turbulence.

[0038] The stirring control device can adjust different stirring rates, stirring directions, and stirring times, effectively improving the contact reaction of various substances in the dissolution reaction tank 1, increasing the contact area of ​​the dissolution reaction, and thus improving the stirring and dissolution reaction efficiency.

[0039] Furthermore, a pressure relief valve 6 is installed on the upper side of the reaction vessel 1. The pressure relief valve 6 is used to connect the atmosphere and the inner cavity 11. The pressure relief valve 6 and the inner cavity 11 are connected by a pipeline. The pressure relief valve 6 is a breather valve. When the internal pressure is too high, it opens to release the pressure inside the reaction vessel 1, ensuring production safety and effectively blocking contact with the atmosphere to avoid particulate matter contamination of the product.

[0040] Furthermore, the reaction vessel 1 is also equipped with a temperature sensor 7 for detecting the temperature of the inner cavity 11. After sensing the temperature, the temperature sensor 7 transmits the temperature information to the dissolution reaction control device 4, which controls the ultrasonic probe 3 and adjusts the input type and input amount of different media according to the internal temperature changes to achieve precise temperature control, ensure sufficient reaction, and improve efficiency.

[0041] The advantage of adopting the above technical solution is that the temperature sensor 7 is set to sense the reaction temperature and is connected to the dissolution reaction control device 4 to realize closed-loop control of the reaction temperature and increase the dissolution efficiency.

[0042] In some embodiments, a heat medium or a cooling medium is introduced into the jacketed cavity 12 through the feed inlet 14. The heat medium can be hot oil or steam, and the cooling medium can be cold water or ethylene glycol solution, which is discharged from the jacketed medium outlet 121. Valves are provided at both the jacketed medium outlet 121 and the liquid outlet 111. When the reaction begins in the reaction tank 1, a heat medium is introduced into the jacketed cavity 12 to maintain the reaction temperature of the inner cavity 11, allowing the internal substances to react fully. After the reaction is completed, a cooling medium is introduced to lower the temperature of the internal medium, facilitating its discharge and effectively improving reaction efficiency.

[0043] In the reaction process, the various reactants to be dissolved first enter the inner cavity 11 of the reaction tank 1 through inlet 13. Different stirring parameters are adjusted by the stirring controller 21. Inlet 14 is opened to input the heat medium, and the ultrasonic probe 3 is turned on to release energy and vibration. The temperature sensor 7 transmits the temperature inside the reaction tank 1 to the dissolution reaction control device 4 to achieve dynamic control. At the same time, the pressure relief valve 6 maintains the dynamic stability of the pressure inside the tank. After the dissolution reaction is completed, stirring is stopped, the ultrasonic probe 3 is turned off, and the control valve of the medium output port in the jacket is opened to output the heat medium. At the same time, the cooling medium is input to start heat dissipation. After cooling, the valve of the liquid outlet 111 is opened, and the compressed air distributor 15 is turned on to spray out the viscous product after the dissolution reaction through compressed air. After discharge, the valve of the liquid outlet 111 is closed, pure water is input into the reaction tank 1 for cleaning, the ultrasonic probe 3 is turned on, stirring is started, and the dissolution reaction tank 1 is cleaned. Finally, the cleaning waste liquid is discharged from the tank through compressed air.

[0044] This application has the following advantages:

[0045] 1. The present invention uses a jacketed dissolution reaction vessel 1 to precisely control the temperature inside the jacket and thus control the problem inside the reaction vessel 1 by inputting and outputting different types and quantities of media; and further improves the efficiency of the dissolution reaction by using an ultrasonic probe 3.

[0046] 2. The stirrer is available in three types: frame type, line type, and fin type. Different stirring speeds, stirring directions, and stirring times can be adjusted through the stirring control device, which can effectively improve the contact reaction of various substances in the dissolution reaction tank 1, increase the contact area of ​​the dissolution reaction, and thus improve the stirring and dissolution reaction efficiency.

[0047] 3. The ultrasonic probe 3 is designed to control the reaction temperature and the contact area of ​​the dissolution reaction in coordination with the jacket by adjusting different ultrasonic frequencies and ultrasonic power; it can also thoroughly clean the dissolution reaction vessel 1 according to the state after the reaction.

[0048] 4. The pressure relief valve 6 is installed to release the pressure inside the dissolution reaction tank 1 and effectively block contact with the atmosphere to prevent particulate matter from contaminating the product;

[0049] 5. The reaction vessel 1 of this application adopts a conical design, which can improve the output efficiency of the product, leave no residue, and is easy to operate;

[0050] 6. This application has a wide range of applications and can be applied to the dissolution reaction process in the preparation of various electronic-grade membrane products.
