[0045] Embodiment 1:

[0046] As Figures 1-6 shown, this embodiment provides a blending kettle for preparing chemical solvents, including:

[0047] Outer shell 1;

[0048] Heat preservation shell 2, arranged inside the outer shell 1;

[0049] Boss 3, arranged on the top of the heat preservation shell 2, and the boss 3 extends parallelly into the heat preservation shell 2;

[0050] Inner shell 4, arranged inside the heat preservation shell 2 and extending upward to protrude from the boss;

[0051] Heating chamber 5, arranged inside the heat preservation shell 2, the inner shell 4 is located inside the heating chamber 5, and the boss 3 closes the heating chamber 5;

[0052] The feed pipe 6 is arranged on the outer shell 1. The feed pipe 6 extends downward to penetrate the boss 3 and extends into the heating chamber 5 of the heat preservation shell 2.

[0053] The stirring mechanism 7 has a plurality of stirring paddles 70. The plurality of stirring paddles 70 are used for large-scale stirring to achieve fine, efficient and uniform mixing.

[0054] The electric heating unit 8 is arranged at the bottom of the heat preservation shell 2 and penetrates the outer shell 1 to heat the solvent in the inner shell 4.

[0055] The vacuum system 9 is configured with a vacuum pump 91 and a vacuum chamber 92, and can maintain the vacuum state of the internal environment during the preparation process, thereby reducing the volatilization and oxidation of the solvent.

[0056] The temperature sensor 10 and the controller 11 are used to monitor and adjust the temperature of the inner shell 4 in real time to ensure the accuracy and stability of the heating process.

[0057] In this technical solution, through optimized design, efficient mixing, precise temperature control and effective vacuum protection are achieved, thereby improving the preparation efficiency and product quality of chemical solvents, reducing the volatilization and oxidation of solvents, and ensuring the safety and stability of the production process.

[0058] Function:

[0059] The stirring mechanism 7: Large-scale stirring is carried out in the preparation kettle through a plurality of stirring paddles 70 to ensure the uniform mixing of the solvent and other chemical components. The plurality of stirring paddles 70 can operate at different speeds and angles, so as to achieve thorough mixing of solvents with high viscosity or complex components. The design of the stirring paddles 70 ensures the uniform distribution of the solvent throughout the inner cavity, thereby improving the mixing efficiency and quality.

[0060] The electric heating unit 8: Heats the solvent in the inner shell 4 to maintain or raise the required working temperature. The electric heating unit 8 transfers heat to the inner shell 4 through a heating coil or a heating jacket to directly heat the solvent therein. The electric heating unit 8 can quickly respond to temperature changes and ensure the required heating effect and temperature stability through precise control.

[0061] The vacuum system 9: Maintains the vacuum state inside the preparation kettle to reduce the volatilization and oxidation of the solvent and protect the quality of the solvent. The vacuum system 9 includes a vacuum pump 91 and a vacuum chamber 92, and creates a low-pressure environment by pumping out the air in the inner cavity. This low-pressure environment helps to reduce the volatilization rate of the solvent and reduce the oxidation reaction, thereby improving the solvent stability during the preparation process.

[0062] Temperature sensor 10 and controller 11: They monitor and adjust the temperature inside the inner shell 4 in real time to ensure the accuracy and stability of the heating process. The temperature sensor 10 measures the actual temperature inside the inner shell 4 and transmits the data to the controller 11. The controller 11 automatically adjusts the power of the electric heating unit 8 according to the preset temperature target to maintain the required temperature, ensuring the precision and stability of the heating process.

[0063] Workflow:

[0064] When the mixing kettle for preparing chemical solvents is needed, first add an appropriate amount of solvent into the inner shell 4, and then start the vacuum system 9. The vacuum pump 91 begins to pump out the air inside the inner shell 4, gradually establishing a vacuum environment. Then, through the feed pipe 6 provided on the outer shell 1, water is introduced into the heating chamber 5 of the heat preservation shell 2, and the electric heating unit 8 is started to heat the water in the heating chamber 5. After the water is heated, the heat is conducted to the inner shell 4, thereby heating the solvent in the inner shell 4. The temperature sensor 10 monitors the temperature of the inner shell 4 in real time and transmits the data to the controller 11. The controller 11 adjusts the power of the electric heating unit 8 according to the set temperature to ensure that the solvent reaches the required working temperature. Subsequently, start the stirring mechanism 7, and multiple stirring paddles 70 start to work at different rotation speeds and angles, stirring and mixing the solvent in the inner shell 4. The design of the stirring paddles 70 ensures large-scale stirring and efficient uniform mixing, adapting to solvents with high viscosity and complex components. During the preparation process, the system continuously monitors the temperature and vacuum degree. The temperature sensor 10 and the vacuum sensor feed the real-time data back to the controller 11, and the controller 11 adjusts the electric heating unit 8 and the vacuum system 9 according to the feedback data to ensure that the temperature and vacuum state during the preparation process are maintained within the set range. After the preparation is completed, stop stirring and heating, release the vacuum state, and restore the air pressure in the kettle to the normal environment. By ending the feeding and performing necessary cleaning operations, ensure that the residues in the kettle body are removed for the next use. The system is equipped with protection devices such as overheating and abnormal vacuum to ensure the safety of the equipment and operators.

[0065] Through the above workflow, the mixing kettle for preparing chemical solvents of the present utility model can efficiently and safely complete the task of preparing chemical solvents, realizing functions such as uniform mixing, precise temperature control, and vacuum protection, improving production efficiency and product quality. Precise temperature adjustment is achieved through the electric heating system and the temperature controller 11 to ensure that the chemical solvents are prepared at an appropriate temperature, avoiding quality problems caused by temperature fluctuations.

[0066] As Figure 1 、 Figure 4 and Figure 5 shown, in this embodiment, optimally, the stirring mechanism 7 includes:

[0067] A top cover 71, provided at the top of the outer shell 1;

[0068] The mounting base 72 is arranged on the top of the top cover 71;

[0069] The motor 73 is arranged on the top of the mounting base 72;

[0070] The transmission shaft 74 is rotatably arranged on the top cover 71. The transmission shaft 74 extends upward through the top cover 71 and is connected to the output shaft of the motor 73. The stirring paddle 70 is arranged on the transmission shaft 74.

[0071] In this technical solution, the utility model improves the structural design of the stirring mechanism 7 to improve the stirring efficiency and operation stability of the dispensing kettle for preparing chemical solvents. By arranging components such as the top cover 71, the mounting base 72, the motor 73, the transmission shaft 74, and the stirring paddle 70, efficient and uniform stirring of chemical solvents is achieved, ensuring the accuracy and efficiency of mixing during the dispensing process, while simplifying the maintenance and operation processes.

[0072] Function:

[0073] The top cover 71: closes the top of the dispensing kettle, protects the internal solvent from external contamination, and provides support for other components of the stirring mechanism 7. The top cover 71 is installed on the top of the outer shell 1, and prevents material leakage through a sealing design, while maintaining the cleanliness and safety of the internal environment.

[0074] The mounting base 72: provides a stable mounting position for the motor 73. The mounting base 72 is arranged on the top of the top cover 71 and fixes the motor 73 to ensure that the motor 73 is not affected by vibration during operation and maintains stable operation.

[0075] The motor 73: provides power to drive the stirring paddle 70. The motor 73 is connected to the transmission shaft 74 through its output shaft. The rotation of the motor 73 transmits mechanical energy to the transmission shaft 74 to drive the stirring paddle 70.

[0076] The transmission shaft 74: transmits the power of the motor 73 to the stirring paddle 70. The transmission shaft 74 is rotatably arranged on the top cover 71, extends upward through the top cover 71, and is connected to the output shaft of the motor 73. The rotation of the transmission shaft 74 drives the stirring paddle 70 to stir, ensuring uniform mixing of the solvent in the dispensing kettle.

[0077] The stirring paddle 70: realizes large-scale stirring of the solvent to ensure uniform mixing of the solvent and other chemical components. The stirring paddle 70 is installed on the transmission shaft 74 and stirs in the kettle as the transmission shaft 74 rotates. The design and layout of the stirring paddle 70 can optimize the stirring effect and adapt to solvents with different viscosities and compositions.

[0078] Working process:

[0079] The operator starts the dispensing kettle and sets parameters such as the stirring speed and the operating state of the motor 73 through the control panel. The motor 73 starts to run, and the output shaft of the motor 73 fixed on the top cover 71 through the mounting seat 72 transmits power to the transmission shaft 74. The motor 73 rotates to drive the transmission shaft 74 to rotate. The transmission shaft 74 rotates stably through the rotating support structure on the top cover 71, effectively transmitting the power of the motor 73 to the stirring paddle 70. As the transmission shaft 74 rotates, the stirring paddle 70 starts to stir inside the inner shell 4. The rotational movement of the stirring paddle 70 enables the solvent and other chemical components to be fully mixed in the dispensing kettle, achieving uniform stirring. The movement of the stirring paddle 70 can cover the entire inner cavity area of the inner shell 4, ensuring the efficiency of large-scale stirring. During the stirring process, the system continuously monitors the stirring state and adjusts according to the set stirring speed. After the stirring is completed, the operation of the motor 73 is stopped, causing the transmission shaft 74 and the stirring paddle 70 to stop rotating. In this way, the stirring task of the chemical solvent can be completed efficiently and stably, achieving efficient and uniform mixing, and improving the dispensing efficiency and product quality.

[0080] Embodiment 2:

[0081] This embodiment provides a dispensing kettle for preparing chemical solvents. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0082] As Figure 1 、 Figure 2 、 Figure 3 and Figure 6 shown, in this embodiment, optimally, the electric heating unit 8 is electrically connected to the temperature sensor 10 and the controller 11 to provide an accurate temperature range to meet the heating requirements of various solvents.

[0083] In this technical solution, the present utility model realizes precise temperature control by electrically connecting the electric heating unit 8 to the temperature sensor 10 and the controller 11 to meet the specific requirements of different chemical solvents during the heating process. This design can improve the accuracy and stability of the heating process, ensure the appropriate temperature range of the chemical solvent, prevent overheating or insufficient heating, and improve production efficiency and product quality.

[0084] Function:

[0085] The electric heating unit 8: provides the necessary heat to heat the solvent in the inner shell 4 and maintains the solvent within the set temperature range. The electric heating unit 8 generates heat through methods such as heating coils, heating jackets, or heating wires, and directly acts on the inner shell 4 through the heat preservation shell 2 to heat the solvent therein.

[0086] Temperature sensor 10: Continuously monitor the temperature inside the inner shell 4 and feedback the measured temperature data to the controller 11. The temperature sensor 10 is installed inside the inner shell 4 to continuously monitor the actual temperature of the solvent, and transmit the data to the controller 11 through an electrical signal, providing real-time temperature information.

[0087] Controller 11: According to the feedback data from the temperature sensor 10, adjust the power of the electric heating unit 8 to keep the temperature of the solvent inside the inner shell 4 within the set range. The controller 11 receives the data transmitted by the temperature sensor 10 and compares it with the preset temperature target. According to the temperature difference, the controller 11 adjusts the power output of the electric heating unit 8 to ensure accurate and stable temperature during the solvent heating process.

[0088] Workflow:

[0089] Through the feed pipe 6 provided on the outer shell 1, water is introduced into the heating chamber 5 of the heat preservation shell 2, and the electric heating unit 8 is started to heat the water in the heating chamber 5. After the water is heated, the heat is conducted to the inner shell 4, thereby heating the solvent in the inner shell 4. The temperature sensor 10 continuously monitors the temperature of the solvent inside the inner shell 4 and transmits the measured temperature data to the controller 11 through an electrical signal. The controller 11 receives the data from the temperature sensor 10 and compares it with the preset temperature target. If the temperature inside the inner shell 4 is lower than the target temperature, the controller 11 will increase the power output of the electric heating unit 8 to improve the heating efficiency; if the temperature inside the inner shell 4 is higher than the target temperature, the controller 11 will reduce the power output of the electric heating unit 8 to avoid overheating. The controller 11 continuously adjusts the power of the electric heating unit 8 to ensure that the temperature inside the inner shell 4 is stable within the set range. Through real-time adjustment, the solvent maintains a constant temperature during the heating process, effectively avoiding problems caused by temperature fluctuations. After the preparation is completed, the electric heating unit 8 is turned off. Through the above workflow, the dispensing kettle for preparing chemical solvents of the present utility model can achieve precise temperature control, ensuring temperature stability and accuracy during the solvent heating process, not only improving the dispensing efficiency, but also avoiding quality problems caused by abnormal solvent temperature, and enhancing the reliability and safety of the overall production process.

[0090] Embodiment 3:

[0091] This embodiment provides a dispensing kettle for preparing chemical solvents. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0092] As Figure 4 and Figure 6 shown, in this embodiment, optimally, the vacuum system 9 includes a pressure sensor 93, which can continuously monitor the vacuum degree inside the inner shell 4 and perform automatic adjustment.

[0093] In this technical solution, the utility model integrates the pressure sensor 93 into the vacuum system 9 to monitor the vacuum degree inside the inner shell 4 in real time and automatically adjust the vacuum level to meet the requirements of different chemical solvents. This design can improve the operation accuracy and stability of the dispensing kettle, prevent production problems caused by unstable vacuum degree, and thus ensure that the chemical solvent maintains the best reaction environment and quality during the preparation process.

[0094] Function:

[0095] Vacuum system 9: Maintains the vacuum degree inside the inner shell 4, prevents external air or other impurities from entering, and avoids possible side reactions or contaminations in the chemical reaction. The vacuum system 9 includes components such as a vacuum pump 91 and a vacuum valve, which are responsible for extracting the air and gas inside the inner shell 4 to maintain the required vacuum degree.

[0096] Pressure sensor 93: Monitors the vacuum degree inside the inner shell 4 in real time and transmits the measured pressure data to the control system for automatic adjustment. The pressure sensor 93 is installed inside the top cover 71, measures the actual pressure inside the inner shell 4, and feeds back the data to the control system in the form of an electrical signal.

[0097] Control system: Automatically adjusts the working state of the vacuum system 9 according to the feedback data of the pressure sensor 93 to maintain the preset vacuum degree. The control system receives the pressure data transmitted by the pressure sensor 93, compares it with the set vacuum target, and automatically adjusts the working state of the vacuum pump 91 or controls the opening and closing of the vacuum valve according to the actual pressure to keep the vacuum degree within the set range.

[0098] Workflow:

[0099] The vacuum system 9 starts to operate, the vacuum pump 91 is started, and the air and gas inside the inner shell 4 are extracted. The pressure sensor 93 starts to work, and the vacuum degree (i.e., the pressure value) inside the inner shell 4 is monitored in real time. The pressure sensor 93 transmits the measured data to the control system through an electrical signal. The control system receives the real-time pressure data from the pressure sensor 93 and compares it with the set vacuum target. If the actual pressure is higher than the target vacuum degree (i.e., the vacuum degree is insufficient), the control system will increase the working intensity of the vacuum pump 91 or open the vacuum valve to further extract air and increase the vacuum degree; if the actual pressure is lower than the target vacuum degree (i.e., over-vacuuming), the control system will reduce the working intensity of the vacuum pump 91 or close some of the vacuum valves to reduce the vacuum degree. The control system continuously monitors the feedback data of the pressure sensor 93 and adjusts the working state of the vacuum system 9 in real time to keep the vacuum degree within the set range. This automatic adjustment process ensures that the vacuum degree inside the inner shell 4 is always stable, meeting different production requirements. When the preparation is completed, the operator can stop the operation of the vacuum system 9. Through the above working process, the mixing kettle for preparing chemical solvents of the present utility model can achieve precise vacuum degree control through the vacuum system 9 integrated with the pressure sensor 93. This design effectively improves the operation accuracy and stability during the preparation process, prevents problems that may be caused by unstable vacuum degree, and ensures the quality and efficiency of chemical solvent preparation.

[0100] Embodiment 4:

[0101] This embodiment provides a mixing kettle for preparing chemical solvents. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0102] As Figure 2 shown, in this embodiment, preferably, a discharge pipe 12 is provided at the bottom of the outer shell 1. The discharge pipe 12 extends upward to penetrate through the heat preservation shell 2 and the inner shell 4, and a ball valve 121 is provided on the discharge pipe 12.

[0103] In this technical solution, the present utility model realizes the effective discharge and control of chemical solvents by providing a discharge pipe 12 at the bottom of the outer shell 1 and installing a ball valve 121 thereon. This design can optimize the outflow process of the solvent, ensure the accuracy and controllability of the discharge, and at the same time maintain the sealing performance and overall function of the mixing kettle.

[0104] Function:

[0105] The discharge pipe 12: provides a channel for the chemical solvent to discharge from the inner shell 4, ensuring that the solvent can flow out smoothly for further processing or packaging. The discharge pipe 12 extends upward from the bottom of the outer shell 1, passes through the heat preservation shell 2 and the inner shell 4, and reaches the bottom of the inner shell 4, allowing the solvent to discharge from the inner shell 4.

[0106] Ball valve 121: Controls the opening and closing state of the discharge pipe 12, precisely adjusts the outflow rate of the solvent, and ensures the safety and accuracy of the discharge process. The ball valve 121 is installed on the discharge pipe 12 and adjusts the opening size of the fluid passage by rotating the ball to achieve the flow control of the solvent.

[0107] Workflow:

[0108] The operator starts the blending kettle and completes the feeding of the solvent. During the operation of the blending kettle, the solvent is heated and mixed inside the inner shell 4 and gradually processed to a predetermined state. When the solvent needs to be discharged, the operator opens the ball valve 121 and rotates the ball valve 121 as needed to control the solvent outflow rate. The opening degree of the ball valve 121 can be adjusted according to actual needs, thereby precisely controlling the flow rate and flow of the solvent. The solvent flows out through the discharge pipe 12 and is collected or processed through the downstream pipeline or container. The operator can monitor the flow rate to ensure that the solvent discharge meets the production requirements. After the discharge is completed, the operator closes the ball valve 121 to stop the solvent outflow. Through the above process and the design of the discharge pipe 12 and the ball valve 121, precise control of the solvent discharge can be achieved, which not only improves the convenience and safety of discharging, but also optimizes the production process, ensures the efficient treatment of chemical solvents, and the stable operation of the system.

A plurality of feeders 13 are provided on the top cover 71, and each feeder 13 is used to add specific raw materials or chemical solvents.

[0115] Control valve 131: Precisely control the amount of raw materials input into the inner shell 4 through the feeder 13 to ensure the accuracy of each feeding. The control valve 131 is installed on each feeder 13 and controls the flow rate and velocity by adjusting the opening and closing degree of the valve, thereby regulating the feeding amount.

[0116] Workflow:

[0117] Before use, the operator checks the status of the feeder 13 and the control valve 131 to ensure that they are not damaged or blocked and can work properly.

Monitor the feeding effect of the feeder 13 and adjust the control valve 131 as needed to ensure that each raw material is correctly added according to the recipe requirements; during the feeding process, fine-tuning can be carried out according to the actual situation to cope with possible changes or deviations in production. After the feeding is completed, close the control valve 131 to ensure that the raw material supply stops and avoid unnecessary leakage. By setting multiple feeders 13 and control valves 131 on the top cover 71, precise control of the feeding process is achieved, which not only improves the flexibility and efficiency of feeding, but also enhances the adaptability of the mixing kettle in dealing with various chemical solvents and raw materials, ensuring the high efficiency of the production process and the quality of the products.

[0118] Example 6:

[0119] This embodiment provides a mixing kettle for preparing chemical solvents. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0120] As Figure 4 shown, in this embodiment, preferably, a pressure gauge 14 for measuring and displaying the pressure value in the inner shell 4 is provided on the top cover 71 to ensure the normal operation of the system.

[0121] In this technical solution, the utility model installs a pressure gauge 14 on the top cover 71 to measure and display the pressure value in the inner shell 4 in real time, ensuring that the chemical solvent mixing kettle can maintain a safe and stable working state during operation. This helps to prevent equipment failures or safety accidents caused by abnormal pressure.

[0122] Function: Pressure gauge 14: Measures and displays the pressure value in the inner shell 4, providing real-time pressure data for the operator to monitor and adjust. The pressure gauge 14 is installed on the top cover 71 and is connected to the pressure measurement point of the inner shell 4 through a connecting pipeline to read and display the actual pressure of the inner shell 4.

[0123] Workflow:

[0124] The operator verifies whether the reading of the pressure gauge 14 is within the normal range to ensure that the equipment status meets the safety operation standards. During the operation of the blending kettle, the operator monitors the pressure value displayed by the pressure gauge 14 in real time. The real-time data provided by the pressure gauge 14 helps the operator determine whether the pressure in the inner shell 4 is within the expected range. If the pressure value abnormally increases or decreases, the operator can take measures in a timely manner to adjust the equipment operation or perform maintenance according to the reading of the pressure gauge 14. If the pressure value displayed by the pressure gauge 14 exceeds the set range, the operator should immediately check whether there are problems in the system, such as valve failures, poor seals or other faults. Appropriate operation steps should be taken according to the actual situation, such as adjusting the feeding amount, reducing the pressure in the inner shell 4 or stopping the operation, to avoid potential safety risks. By setting the pressure gauge 14 on the top cover 71, the pressure value in the inner shell 4 can be monitored in real time, which not only enhances the safety and reliability of the system, but also improves the operator's control ability of the equipment operation status, ensuring the smooth progress of the chemical solvent blending process.

[0125] As Figures 1-3 shown, in this embodiment, optimally, mounting plates 15 for installation at designated positions are provided on both sides of the outer shell 1, and a plurality of slotted holes 151 are provided on the mounting plates 15.

[0126] In this technical solution, the utility model provides mounting plates 15 on both sides of the outer shell 1 of the blending kettle for preparing chemical solvents, and a plurality of slotted holes 151 are provided on the mounting plates 15 to facilitate the stable installation of the blending kettle at the designated position.

[0127] Function:

[0128] Mounting plates 15: Provide fixed and supporting points for the blending kettle, enabling it to be stably installed at the designated position, ensuring the stability of the equipment and operation safety. The mounting plates 15 are fixed on both sides of the outer shell 1 of the blending kettle and can bear the weight of the equipment and the stress during operation.

[0129] Slotted holes 151: Provide hole positions for installation and adjustment, facilitating the use of bolts or other fasteners to fix the mounting plates 15 to the basic structure. The design of the slotted holes 151 allows a certain adjustment range to ensure that the installation position can be finely adjusted during the actual installation process to adapt to different installation conditions and requirements.

[0130] Workflow:

[0131] According to the layout of the production site and equipment requirements, determine the final installation position of the dispensing kettle, mark the hole positions of the waist-shaped holes 151 on the mounting plate 15 at the installation position to ensure the correct docking position with the basic structure. Align the mounting plate 15 with the predetermined installation position, dock the waist-shaped holes 151 with the screw holes on the basic structure, and use bolts and nuts to fix the mounting plate 15 on the basic structure. The design of the waist-shaped holes 151 allows a certain adjustment range to ensure that the mounting plate 15 can be accurately docked. If necessary, fine-tune the position of the mounting plate 15 by adjusting the tightening degree of the bolts to ensure that the horizontal and vertical directions of the dispensing kettle meet the requirements. By setting the mounting plate 15 and the waist-shaped holes 151 on both sides of the outer shell 1, the stable installation of the dispensing kettle is realized, which not only simplifies the installation process, but also enhances the stability and safety of the equipment, ensuring that the dispensing kettle can operate normally and safely during the production process.
