[0027] Example

[0028] Reference Figures 1-4 This embodiment of the present invention provides an organic solvent recovery device for the production of 2-methyl-1,4-naphthoquinone, comprising:

[0029] The main body of the receiving container 100 is used for collecting and temporarily storing recycled organic solvents;

[0030] The regulating mechanism 200 is installed on the receiving container body 100 and is used to regulate and control the flow rate and pressure of the organic solvent entering or exiting.

[0031] The regulating mechanism 200 includes a connecting component 201 and a control component 202;

[0032] The connecting component 201 includes a connecting port 2011 and a connecting tube 2012. The connecting port 2011 is provided on the receiving container body 100, and the connecting tube 2012 is fixedly connected to the connecting port 2011.

[0033] The control assembly 202 includes a control valve 2021 and a regulator 2022. The control valve 2021 is mounted on the connecting pipe 2012, and the regulator 2022 is signal-connected to the control valve 2021.

[0034] Specifically, the connection port 2011 has a flange interface structure, and the connecting pipe 2012 is detachably connected to the connection port 2011 through the flange, which facilitates installation and maintenance.

[0035] It should be noted that the flange interface design not only ensures the sealing and stability of the connection, but also facilitates quick disassembly and maintenance, reducing equipment downtime and improving work efficiency. This design is particularly suitable for applications requiring frequent pipe cleaning or replacement, ensuring ease of operation without affecting the overall system performance.

[0036] Specifically, the control valve 2021 is an electrically adjustable valve that can automatically adjust its opening degree according to external input signals to achieve precise control of the organic solvent flow rate.

[0037] It should be noted that the electric regulating valve employs advanced sensing technology and an intelligent control system, enabling it to automatically adjust the valve opening based on real-time monitoring data, thereby achieving precise control of the organic solvent flow rate. Furthermore, this valve features fast response and high adjustment accuracy, maintaining stable performance under complex operating conditions and significantly improving the safety and efficiency of the entire recycling process.

[0038] Specifically, the regulator 2022 is a controller, equipped with a parameter input interface and a feedback signal acquisition module, which can monitor and adjust the working status of the control valve 2021 in real time.

[0039] It should be noted that the controller 2022 is equipped with a user-friendly parameter input interface and a highly sensitive feedback signal acquisition module, allowing operators to flexibly set operating parameters according to actual needs and monitor the system's operating status in real time. Through a closed-loop control mechanism, the controller can promptly detect and correct deviations, ensuring that the control valve 2021 is always in optimal working condition, effectively preventing operational errors or equipment malfunctions caused by improper parameter settings.

[0040] Specifically, the receiving container body 100 is equipped with a liquid level sensor, which is connected to the regulator 2022 for automatically starting and stopping the control valve 2021 according to the liquid level.

[0041] It should be noted that the liquid level sensor adopts non-contact measurement technology, featuring high precision and long lifespan, and can operate stably in harsh environments. Its signal connection with the regulator 2022 enables automated management; when the liquid level reaches the preset value, the system automatically starts or stops the relevant operations, avoiding errors and delays caused by manual intervention, and further improving the system's reliability and safety.

[0042] Specifically, the outer wall of the receiving container body 100 is provided with a heat insulation layer, which is made of corrosion-resistant material and is used to maintain the internal solvent temperature stability and prevent evaporation or condensation.

[0043] It should be noted that the insulation layer is made of high-efficiency thermal insulation material, which not only effectively reduces heat loss but also resists the influence of the external environment on the internal temperature, ensuring that organic solvents are stored within a suitable temperature range. Furthermore, this insulation layer has excellent corrosion resistance, remaining intact even after long-term exposure to chemical environments, extending the equipment's lifespan and reducing maintenance costs.

[0044] During use, first ensure that the main body 100 of the receiving container is correctly installed and that its outer insulation layer is intact to maintain a stable internal solvent temperature and prevent evaporation or condensation due to temperature changes. The connecting assembly 201 securely connects the connecting port 2011 to the connecting pipe 2012 via a flange interface structure. This design not only ensures sealing but also facilitates quick disassembly and maintenance, improving the operability and maintenance efficiency of the equipment. When organic solvent recovery is required, the control component 202 in the regulating mechanism 200 begins to function. The control valve 2021, as an electrically adjustable valve, automatically adjusts its opening based on external input signals, precisely controlling the flow rate of organic solvent entering or exiting the main body 100 of the receiving container. Simultaneously, the regulator 2022, as a controller, is equipped with a parameter input interface and a feedback signal acquisition module, which can monitor and adjust the operating status of the control valve 2021 in real time, ensuring the stability and safety of the system operation. Furthermore, the liquid level sensor inside the receiving container 100 is connected to the regulator 2022, automatically starting and stopping the control valve 2021 based on the liquid level, thus avoiding the risks of overfilling or emptying and further improving the system's automation level and reliability. Throughout the operation, users can easily set various parameters through the regulator 2022's parameter input interface and monitor the entire process using the feedback signal acquisition module, achieving precise control of the organic solvent recovery process and meeting specific needs under different operating conditions.

[0045] In summary, by setting up the main body 100 of the collection container and the regulating mechanism 200, the automated control of the organic solvent recovery process is realized, which effectively improves the recovery efficiency and operational safety. The connecting component 201 adopts a flange-type detachable structure, which facilitates installation and maintenance and improves the applicability of the equipment. With the electric control valve 2021 and the intelligent regulator 2022, the flow rate can be accurately controlled to achieve closed-loop control and ensure the stable and reliable operation of the system. The design of the liquid level sensor and the heat preservation layer further enhances the functional integrity of the device and reduces energy consumption and maintenance costs.
