Human factors can easily lead to abnormal reactions, affecting the yield and quality of organic acids. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic addition device for the preparation of organic acids.

[0010] Preferably, the inner wall of the liquid storage tank is equipped with a liquid level sensor, and the liquid level sensor is fitted to the liquid storage tank.

[0011] Preferably, one side of the liquid storage tank is provided with a heat insulation layer, and the heat insulation layer is bonded to the liquid storage tank.

[0012] Preferably, a metering pump is provided at the top of the second inlet, and the metering pump is threadedly connected to the second inlet.

[0013] Beneficial effects

[0014] This invention employs a metering pump mounted on the top of the storage tank, which precisely controls the amount of raw materials added based on parameters pre-set in the controller. Compared to manual addition, this significantly reduces errors in raw material proportions caused by inaccurate human operation, ensuring the accuracy of raw material input in each batch of organic acid preparation, thereby stabilizing product quality. Furthermore, the metering pump, directly installed on the top of the storage tank, controls the outflow of raw materials from the source. Combined with precise parameter settings in the controller, the accuracy of raw material addition can be controlled within a very small error range. Compared to traditional manual addition based on experience or simple measuring tools, this method strictly adheres to process formulation requirements, precisely adding every single drop of raw material. The controller also features flexible programming capabilities, allowing for quick adaptation to new raw material addition requirements by simply adjusting the metering pump parameters on the controller's operating interface, regardless of the specific organic acid preparation process, such as different acid synthesis routes or reaction conditions. Whether it's the synthesis of simple dicarboxylic acids or the preparation of complex polycarboxylic acids, the device can handle both precisely.

[0015] In this invention, a liquid level sensor is installed inside the storage tank to monitor the raw material level in real time. Once the level approaches the lower limit, a signal is quickly transmitted to the controller, which promptly takes measures such as suspending the relevant metering pumps. This effectively avoids equipment damage caused by empty pump operation and interruptions in raw material addition, ensuring the continuity and stability of production. Similarly, a temperature sensor on the reactor provides real-time temperature feedback, facilitating precise adjustment of the reaction temperature by external temperature control equipment, providing suitable reaction conditions for organic acid preparation. Simultaneously, through the coordinated operation of the liquid level sensor and the controller, the raw material supply status is precisely controlled at all times, ensuring a seamless raw material addition process. Whether for long-term continuous production or dealing with unstable raw material supply, timely adjustments can be made based on liquid level feedback to ensure that there is always sufficient raw material in the reactor to participate in the reaction, maintaining the continuity of the organic acid preparation reaction, ensuring product quality stability, and avoiding problems such as incomplete reaction and increased product impurities caused by raw material interruptions.

[0016] In this invention, an insulation layer is wrapped around the outside of the storage tank. This reduces the impact of external ambient temperature on the raw materials, maintains the stability of their physicochemical properties, and ensures that the raw materials remain in good condition during storage and addition, thus improving the quality of organic acid products. This effectively blocks interference from external temperature fluctuations on the raw materials inside the storage tank. For some temperature-sensitive organic acid preparation raw materials, such as substances that are prone to volatility and decomposition at high temperatures or crystallization and aggregation at low temperatures, a stable storage temperature environment ensures their constant physicochemical properties. This avoids problems such as raw material deterioration and reduced activity caused by temperature changes, ensuring that the raw materials added to the reaction are always in optimal condition.

Detailed Implementation

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-4 An automatic addition device for the preparation of organic acids includes a reaction vessel 1. A limiting ring 11 is provided on one side of the reaction vessel 1, and a support rod 14 is provided on the top of the limiting ring 11. A top cover 2 is provided on the top of the reaction vessel 1, and a controller 4 is provided on the top of the top cover 2. The bottom of the controller 4 is threadedly connected to the top of the top cover 2. A drive motor 6 is provided on the top of the top cover 2, and a rotating rod 9 is provided at the bottom of the drive motor 6. Two stirring blades 10 are provided on one side of the rotating rod 9, and the two stirring blades 10 are respectively positioned and connected to the rotating rod 9. A first liquid inlet 3 is provided on the top of the top cover 2, a temperature sensor 5 is provided on the top of the top cover 2, and a delivery pipe 7 is provided on the top of the top cover 2. A first valve 15 is provided on one side of the delivery pipe 7, and the first valve 15 is connected to the delivery pipe 7. The conveying pipe 7 is connected by threads. The top of the conveying pipe 7 is equipped with a storage tank 16. The inner wall of the storage tank 16 is equipped with a liquid level sensor 18. The first valve 15 and the liquid level sensor 18 are electrically connected to the controller 4. The liquid level sensor 18 and the storage tank 16 are fitted together. The storage tank 16 is equipped with a heat insulation layer 17 on one side. The heat insulation layer 17 and the storage tank 16 are fitted together. The top of the storage tank 16 is equipped with a second liquid inlet 19. The top of the second liquid inlet 19 is equipped with a metering pump 8. The metering pump 8 and the second liquid inlet 19 are connected by threads. The bottom of the reactor 1 is equipped with a discharge port 12. The bottom of the reactor 1 is equipped with a support foot 13. The side of the discharge port 12 is equipped with a second valve 20. The second valve 20 and the metering pump 8 are electrically connected to the controller 4.

[0027] When preparing organic acids, the flow rate, running time, and other parameters of each metering pump 8 are first set through the operating interface of the controller 4. The required raw materials are injected into the corresponding storage tanks 16 through the second inlet 19. After starting the device, the controller 4 opens the first valve 15 and the metering pump under the corresponding storage tank 16 according to the settings. The raw materials are accurately metered by the metering pump 8 and flow to the reactor 1 through the delivery pipe. The liquid level sensor 18 monitors the liquid level in the storage tank 16 at all times. If the liquid level is close to the lower limit, a signal is transmitted in time, and the controller 4 can take measures such as pausing the relevant metering pumps to prevent the pumps from running dry. Inside the reactor 1, the temperature sensor 5 monitors the temperature. If it deviates from the suitable reaction temperature, an external temperature control device can be connected for adjustment. The stirring blade 10 ensures that the raw materials are mixed evenly and promotes efficient reaction. After the reaction is completed, the second valve 20 on the discharge port 12 at the bottom of the reactor 1 is opened to remove the organic acid product. Specific Implementation Example 2:

[0029] Reference Figure 1-4 The 16 storage tanks adopt a quick-release connection structure, which is connected by a magnetic interface. This not only ensures the sealing of the connection and prevents raw material leakage, but also allows the staff to quickly complete the disassembly operation when a storage tank needs to be replaced or repaired, without the need for complicated tools, saving maintenance time and improving the overall operating efficiency of the production line.

[0030] In summary:

[0031] 1. A metering pump 8 is installed on the top of the storage tank 16. Based on parameters pre-set in the controller 4, it precisely controls the amount of raw materials added. Compared to manual addition, this significantly reduces errors in raw material proportions caused by inaccurate human operation, ensuring the accuracy of raw material input in each batch of organic acid preparation, thus stabilizing product quality. Simultaneously, the metering pump 8, directly installed on the top of the storage tank 16, controls the outflow of raw materials from the source. Combined with precise parameter settings in the controller 4, the accuracy of raw material addition can be controlled within a very small error range. Compared to traditional manual addition based on experience or simple measuring tools, this method strictly adheres to process formula requirements, accurately adding every single drop of raw material. Furthermore, the controller 4 has flexible programming capabilities. For different types of organic acid preparation processes, such as different acid synthesis routes and different reaction conditions, simply adjusting the parameters of the metering pump 8 on the controller 4's operating interface allows for rapid adaptation to new raw material addition requirements. Whether it's the synthesis of simple dicarboxylic acids or the preparation of complex polycarboxylic acids, the device can handle it precisely.

[0032] 2. A liquid level sensor 18 is installed inside the storage tank 16 to monitor the liquid level in real time.

[0033] The internal raw material level sensor quickly transmits a signal to controller 4 when the liquid level approaches the lower limit. Controller 4 then promptly takes measures such as suspending the relevant metering pumps 8, effectively avoiding equipment damage caused by empty pump operation and interruption of raw material addition, ensuring the continuity and stability of production. Temperature sensor 5 on reactor 1 also provides real-time temperature feedback, facilitating precise adjustment of the reaction temperature by external temperature control equipment, providing suitable reaction conditions for organic acid preparation. Simultaneously, through the coordinated operation of liquid level sensor 18 and controller 4, the raw material supply status is precisely monitored at all times, ensuring seamless integration of the raw material addition process. Whether in long-term continuous production or dealing with unstable raw material supply, timely adjustments can be made based on liquid level feedback to ensure that there is always sufficient raw material in reactor 1 to participate in the reaction, maintaining the continuity of the organic acid preparation reaction, ensuring product quality stability, and avoiding problems such as incomplete reaction and increased product impurities caused by raw material interruption.

[0034] 3. By wrapping the outside of the storage tank 16 with an insulation layer 17, the influence of external environmental temperature on the raw materials is reduced, maintaining the stability of the raw materials' physicochemical properties and ensuring that the raw materials are always in good condition during storage and addition. This is beneficial for improving the quality of organic acid products and effectively blocks the interference of external environmental temperature fluctuations on the raw materials inside the storage tank 16. For some temperature-sensitive raw materials for the preparation of organic acids, such as substances that are prone to volatility and decomposition at high temperatures and crystallization and agglomeration at low temperatures, a stable storage temperature environment can ensure the constant physicochemical properties. This avoids problems such as raw material deterioration and reduced activity caused by temperature changes, ensuring that the raw materials added to the reaction are always in optimal condition.
