Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 3 and Figure 5 An embodiment of this utility model is provided: a dissolving device for the production of aminosulfonic acid, including a support 1 and a top cover 2. A dissolving mechanism 3 is provided between adjacent parts of the support 1 and the top cover 2. The dissolving mechanism 3 is used to stir and dissolve the raw material of aminosulfonic acid. A temperature control mechanism 4 is provided on the outside of the dissolving mechanism 3. The temperature control mechanism 4 is used to control the temperature of the dissolving environment.

[0034] The dissolving mechanism 3 includes a tank 31 made of 316 stainless steel. The bottom of the inner side of the tank 31 is rounded. The bottom of the tank 31 is fixedly connected to the top of the support 1. The top of the top cover 2 is fixedly connected to a motor 32. The inner side of the top of the top cover 2 is fixedly connected to a fixed bearing 33. The bottom of the motor 32 is fixedly connected to a stirring rod 35. The outer side of the bottom of the stirring rod 35 is provided with a spherical structure. The bottom of the stirring rod 35 adopts a rounded streamline structure.

The top of the motor 38 is fixedly connected to a turbine propeller 39.

[0035] A feeding assembly 310 is provided on the top right side of the top cover 2. The feeding assembly 310 includes a feeding hopper 3101. The bottom of the feeding hopper 3101 is fixedly connected to the top right side of the top cover 2. A cover 3102 is provided on the top of the feeding hopper 3101. A liquid inlet assembly 311 is provided on the top left side of the top cover 2. The liquid inlet assembly 311 includes a solenoid valve 3111. The bottom of the solenoid valve 3111 is fixedly connected to the top left side of the top cover 2. A liquid inlet seat 3112 is fixedly connected to the top of the solenoid valve 3111. A discharge assembly 312 is provided on the bottom right side of the tank body 31. The discharge assembly 312 includes a ball valve 3121. The top of the ball valve 3121 is fixedly connected to the bottom right side of the tank body 31. An angular stroke actuator 3122 is fixedly connected to the right side of the ball valve 3121.

[0036] Specifically, when the dissolving mechanism 3 is working, the motor 32 at the top of the top cover 2 starts, driving the stirring rod 35 at the bottom to rotate. The stirring frames 34 on the left and right sides of the stirring rod 35 rotate synchronously to stir the material in the tank 31. The spherical structure and the arc-shaped streamlined structure at the bottom of the stirring rod 35 reduce the stirring resistance. Through the cooperation of the motor 32 and the stirring rod 35, the dissolution of the material is accelerated.

[0037] The fixed bearing 33 on the inner side of the top of the top cover 2 supports and fixes the stirring rod 35. The airtight bearing 36 at the bottom of the tank body 31 enhances the sealing when the stirring rod 35 rotates. Through the cooperation of the fixed bearing 33 and the airtight bearing 36, the stirring process is stable and sealed.

[0038] When the motor 2 38 at the bottom of the top cover 2 is started, it drives the turbine 39 at the top to rotate. The water flow generated by the turbine 39 pushes the material deposited at the bottom to circulate and flow, forming a synergistic mixing effect with the mixing frame 34. Through the cooperation of the motor 2 38 and the turbine 39, the uniformity of material mixing is improved.

[0039] The sealing disc 37 at the bottom of the top cover 2 enhances the sealing between the airtight bearing 36 and the tank body 31, preventing material leakage. The cooperation between the sealing disc 37 and the tank body 31 ensures the airtightness of the dissolving environment.

[0040] In the top right side of the feeding assembly 310, when the cover 3102 is opened, the material enters the tank 31 through the feeding hopper 3101. The material can be conveniently added through the cooperation of the feeding hopper 3101 and the cover 3102.

[0041] In the liquid inlet assembly 311 on the top left, the solenoid valve 3111 is opened, and the liquid is injected into the tank 31 through the infusion seat 3112. Through the cooperation of the solenoid valve 3111 and the infusion seat 3112, the precise control and addition of liquid can be achieved.

[0042] In the discharge assembly 312 on the bottom right side of the tank body 31, the angular stroke actuator 3122 drives the ball valve 3121 to open, and the dissolved material is discharged through the ball valve 3121. The material is discharged through the cooperation of the ball valve 3121 and the angular stroke actuator 3122.

[0043] Reference Figure 1 , Figure 2 and Figure 4 The temperature control mechanism 4 includes a jacket 41, the inner side of which is fixedly connected to the outer side of the tank body 31. Two water injection seats 42 are fixedly connected to the right side of the jacket 41. A heat insulation sleeve 43 is provided on the outer side of the jacket 41. A sealing ring 44 is fixedly connected to the top and bottom of the inner side of the heat insulation sleeve 43. An installation groove 45 is provided on the top and bottom of the outer wall of the tank body 31. A monitoring component 46 is provided on the bottom of the inner side of the tank body 31. The monitoring component 46 includes a temperature sensor 461. The bottom of the temperature sensor 461 is fixedly connected to the right end of the bottom of the inner side of the tank body 31. A liquid level sensor 462 is fixedly connected to the left end of the bottom of the inner side of the tank body 31.

[0044] Specifically, when the temperature control mechanism 4 is working, a temperature regulating medium is introduced into the jacket 41 on the outside of the tank 31. The temperature of the material in the tank 31 is changed through heat exchange between the medium and the tank 31. The two water injection seats 42 on the right side of the jacket 41 are used for the injection and discharge of the medium. The temperature of the material is regulated by the cooperation between the jacket 41 and the water injection seats 42.

[0045] The heat insulation sleeve 43 on the outside of the jacket 41 reduces heat transfer and reduces the influence of the external environment on the temperature of the medium inside the jacket 41. The sealing rings 44 at the top and bottom of the inner side of the heat insulation sleeve 43 cooperate with the mounting grooves 45 on the outer wall of the tank 31 to enhance the sealing between the heat insulation sleeve 43 and the tank 31. Through the cooperation of the heat insulation sleeve 43 and the sealing rings 44, heat loss is reduced.

[0046] Temperature sensor 461 at the bottom right of the inner side of tank 31 monitors the temperature of the material in real time. Temperature sensor 461 adopts model IPRT-300, with an accuracy of ±0.04°C and a temperature range of -45 to 300°C, providing data support for temperature regulation. Liquid level sensor 462 at the bottom left of the inner side monitors the liquid level of the material. Liquid level sensor 462 adopts model LFV300, with a liquid level detection range of up to 6m and a protection level of IP67. Through the cooperation of temperature sensor 461 and liquid level sensor 462, real-time monitoring of the material status is achieved.

[0047] When the temperature sensor 461 detects that the material temperature deviates from the set range, the medium of the corresponding temperature is injected into the jacket 41 through the water injection seat 42. The material temperature is adjusted by the heat exchange between the jacket 41 and the tank 31. The heat insulation sleeve 43 maintains the temperature stability inside the jacket 41 and reduces heat loss during the adjustment process.

[0048] When the liquid level sensor 462 detects an abnormal liquid level, it can work with the feeding assembly 310 and the liquid inlet assembly 311 to replenish and adjust the material, ensuring that the temperature regulation process is not affected by the liquid level.

[0049] During operation, the jacket 41 and water injection seat 42 achieve temperature regulation, the heat insulation sleeve 43 and sealing ring 44 reduce heat loss, and the monitoring component 46 provides data support to control the temperature of the material inside the tank 31, ensuring that the material dissolution process is carried out at a suitable temperature.

[0050] Working principle: Material is added through the feeding component 310 of the dissolving mechanism 3. The cap 3102 is opened and the aminosulfonic acid raw material enters the tank 31 through the feeding hopper 3101. After feeding is completed, the cap 3102 is closed to prevent impurities from entering. The solenoid valve 3111 of the liquid inlet component 311 is opened and the liquid is injected into the tank 31 through the liquid inlet seat 3112 according to the set amount. After the injection is completed, the solenoid valve 3111 is closed to avoid excessive liquid and leakage.

[0051] The dissolving mechanism 3 begins the stirring and dissolving operation. The motor 32 on the top of the top cover 2 starts, driving the stirring rod 35 at the bottom to rotate. The stirring frames 34 on the left and right sides of the stirring rod 35 rotate synchronously, fully stirring the aminosulfonic acid raw material and liquid in the tank 31. The spherical structure and arc-shaped streamlined structure at the bottom of the stirring rod 35 reduce the contact resistance with the material during rotation, making the stirring smoother. The motor 38 at the bottom of the top cover 2 starts, driving the turbine 39 at the top to rotate. The water flow generated by the turbine 39 pushes the material deposited at the bottom of the tank 31 upward to circulate, forming a coordinated stirring effect with the stirring frames 34, further improving the uniformity of material mixing and accelerating the dissolution of aminosulfonic acid.

[0052] The fixed bearing 33 on the inner side of the top of the top cover 2 provides stable support and fixation for the stirring rod 35, preventing the stirring rod 35 from shifting when rotating at high speed. The airtight bearing 36 at the bottom of the tank body 31 enhances the sealing performance of the stirring rod 35 during rotation, preventing material leakage from the rotation gap. Through the cooperation of the fixed bearing 33 and the airtight bearing 36, the entire stirring process is ensured to be stable and sealed. The sealing plate 37 at the bottom of the tank body 31 fits against the bottom of the airtight bearing 36, enhancing the sealing performance between the airtight bearing 36 and the tank body 31, preventing material leakage, and ensuring the airtightness of the dissolving environment.

[0053] During the dissolution process, the temperature control mechanism 4 works synchronously to control the temperature of the dissolution environment. The temperature regulating medium is introduced into the jacket 41 on the outside of the tank 31. The two water injection seats 42 on the right side of the jacket 41 are responsible for the injection and discharge of the medium, respectively. By adjusting the temperature and flow rate of the medium, the temperature of the material in the tank 31 is changed by the heat exchange between the medium and the tank 31, thereby achieving the regulation of the material temperature. The heat insulation sleeve 43 on the outside of the jacket 41 reduces the heat transfer between the jacket 41 and the external environment, reducing the influence of the external environment on the temperature of the medium in the jacket 41. The sealing rings 44 at the top and bottom of the inner side of the heat insulation sleeve 43 are tightly fitted with the mounting groove 45 on the outer wall of the tank 31, which enhances the sealing between the heat insulation sleeve 43 and the tank 31, reduces heat loss, and maintains the stability of the temperature of the medium in the jacket 41.

[0054] Temperature sensor 461 at the bottom right of the inner side of tank 31 monitors the temperature of the material in real time and feeds back the data. When the material temperature is detected to deviate from the set range, the temperature and flow rate of the medium introduced into the jacket 41 are adjusted through water injection seat 42. The material temperature is adjusted to a suitable range in time by utilizing the heat exchange between the jacket 41 and tank 31. Liquid level sensor 462 at the bottom left of the inner side of tank 31 monitors the liquid level of the material in real time. When an abnormal liquid level is detected, it can be used in conjunction with feeding assembly 310 and liquid inlet assembly 311 to replenish and adjust the material, ensuring that the temperature regulation process is not affected by abnormal liquid level and ensuring the stable operation of the dissolving process.

[0055] Once the aminosulfonic acid raw material is completely dissolved, the discharge assembly 312 on the bottom right side of the tank 31 starts working. The angular stroke actuator 3122 drives the ball valve 3121 to open, and the dissolved aminosulfonic acid solution is discharged through the ball valve 3121, completing the entire dissolution operation and realizing the dissolution and treatment of the aminosulfonic acid raw material.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
