Description

Technical Field

[0001] This utility model relates to the technical field of pressure regulation, and in particular to a steam pressure regulating device for an extraction tank jacket. Background Technology

[0002] Extraction tanks are crucial devices for achieving effective mass transfer between materials and solvents. During operation, they typically require external heat sources to heat the tank body to maintain or increase the temperature of the material inside, meeting the extraction requirements of different process stages. Currently, the most widely used heating method is jacketed steam heating, which involves introducing steam into a jacket cavity surrounding the outer wall of the tank, utilizing the latent heat released by steam condensation to indirectly heat the material inside.

[0003] However, traditional jacketed structures are mostly one-piece designs, with steam evenly distributed throughout the jacket. This makes it difficult to achieve precise temperature control by zone or segment based on the actual liquid level of the material inside the tank, the distribution of heat transfer intensity, and changes in the process stage. This not only easily leads to uneven temperature problems such as overheating of the upper material and insufficient heating of the lower material, but may also cause decomposition or deterioration of heat-sensitive components due to localized overheating, affecting extraction efficiency and product quality stability. At the same time, one-piece jackets are prone to generating significant thermal stress during start-up and shutdown, which may accelerate equipment fatigue and affect the service life of the equipment under long-term operation.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a steam pressure regulating device for the extraction tank jacket is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a steam pressure regulating device for the jacket of an extraction tank.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a steam pressure regulating device for an extraction tank jacket, comprising: a tank body, and a steam pressure regulating component disposed on one side of the tank body;

[0007] The tank body is provided with a jacketed groove, and two partitions are fixedly connected in the jacketed groove. The two partitions divide the jacketed groove into an upper adjustment groove, a middle adjustment groove and a lower adjustment groove.

[0008] The steam pressure regulating assembly includes: a plurality of diversion pipes, the plurality of diversion pipes being connected to the outer circumference of the tank body, the plurality of diversion pipes being respectively connected to the upper regulating trough, the middle regulating trough and the lower regulating trough, the ends of the plurality of diversion pipes away from the tank body being connected to the same steam guide pipe, and the other end of the steam guide pipe being connected to a gas-fired steam generator.

[0009] Each of the upper, middle, and lower regulating tanks is equipped with a sensing module, which includes a pressure sensor and a temperature sensor. The pressure sensor and temperature sensor are located downstream of the steam inlet of the corresponding upper, middle, and lower regulating tanks, and at the middle height of the side wall of the regulating tank.

[0010] In a preferred embodiment of this invention, the pressure sensor is a piezoresistive or capacitive pressure transmitter, and the temperature sensor is a platinum resistance thermometer.

[0011] In a preferred embodiment of this utility model, the jacket groove is a closed cavity structure located on the outer wall of the tank.

[0012] In a preferred embodiment of this utility model, the partition is made of stainless steel and has a thickness of 6 mm.

[0013] In a preferred embodiment of this utility model, a plurality of material temperature sensors are evenly distributed vertically on the inner circumference of the tank.

[0014] In a preferred embodiment of this utility model, the bottom pipe of the tank is connected to a discharge pipe.

[0015] In a preferred embodiment of this utility model, a valve for controlling material discharge is provided on the outer wall of the discharge pipe.

[0016] In a preferred embodiment of this invention, the top pipe of the tank is connected to an inlet pipe.

[0017] In a preferred embodiment of this utility model, the bottom of the tank is fixedly connected with several support feet.

[0018] In a preferred embodiment of this invention, the bottom of each of the several support feet has a protective pad.

[0019] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0020] (1) This utility model provides a steam pressure regulating device for the jacket of an extraction tank. By dividing the jacket space into three independent regulating areas—upper, middle, and lower—and equipping them with independent steam diversion pipelines and sensing modules, it achieves precise zoned control of the jacket heating process. Through the segmented structure, the steam supply can be adjusted according to the heat transfer requirements of different areas. Especially when processing materials with different liquid levels or those sensitive to temperature, it can effectively avoid the problem of overheating in the upper part and insufficient heating in the lower part caused by traditional integral jackets. It significantly improves the uniformity of heating of materials in the tank and the controllability of the process, thereby ensuring the stability of the extraction process and the consistency of product quality.

[0021] (2) This utility model provides a steam pressure regulating device for extraction tank jacket. By setting a sensing module consisting of a pressure sensor and a temperature sensor and installing it downstream of the steam inlet and in the middle of the side wall, avoiding areas where bubbles and condensate are easily accumulated, the accuracy and reliability of the monitoring data are ensured. These real-time feedback parameters provide the control basis for the device body. Combined with the regulating valve, it can realize closed-loop intelligent regulation of steam flow and pressure, which not only improves energy utilization efficiency and reduces unnecessary heat energy waste, but also reduces the damage to the equipment structure caused by thermal stress due to drastic temperature fluctuations, and helps to extend the service life of the equipment.

[0022] (3) This utility model provides a steam pressure regulating device for the jacket of an extraction tank. By using multiple material temperature sensors distributed vertically on the inner wall of the tank, the temperature field distribution of the material inside the tank can be constructed in real time, so as to fully grasp the heating status, further optimize the heating strategy of each section of the jacket, and enhance the adaptability of the equipment to different extraction processes by combining zoned heating, multi-point monitoring and intelligent linkage regulation. It is particularly suitable for the extraction of heat-sensitive components, effectively prevents the decomposition of effective components caused by local overheating, and improves extraction efficiency and product quality.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] like Figure 1 As shown, an extraction tank jacket steam pressure regulating device includes: a tank body 1, and a steam pressure regulating component 5 disposed on one side of the tank body 1;

[0029] like Figures 1-2As shown, the tank body 1 is provided with a jacketed groove 6. The jacketed groove 6 is a closed cavity structure located on the outer wall of the tank body 1. Two partitions 501 are fixedly connected inside the jacketed groove 6. The material of the partitions 501 is stainless steel and the thickness of the partitions 501 is 6 mm. The two partitions 501 divide the jacketed groove 6 into an upper adjustment groove 505, a middle adjustment groove 506 and a lower adjustment groove 507.

[0030] The steam pressure regulating assembly includes: a plurality of branch pipes 504, which are connected to the outer circumference of the tank 1. The plurality of branch pipes 504 are respectively connected to the upper regulating channel 505, the middle regulating channel 506 and the lower regulating channel 507. The end of the plurality of branch pipes 504 away from the tank 1 is connected to the same steam guide pipe 503, and the other end of the steam guide pipe 503 is connected to a gas-fired steam generator.

[0031] Sensing modules 7 are provided in the upper regulating tank 505, the middle regulating tank 506 and the lower regulating tank 507. The sensing modules 7 include a pressure sensor and a temperature sensor. The pressure sensor and the temperature sensor are located downstream of the steam inlet of the corresponding upper regulating tank 505, middle regulating tank 506 and lower regulating tank 507, and are located at the middle height of the side wall of the regulating tank.

[0032] The pressure sensor is a piezoresistive or capacitive pressure transmitter, and the temperature sensor is a platinum resistance thermometer.

[0033] It should be noted that the baffle 501 is arranged in a ring shape, dividing the jacket groove 6 vertically into an upper regulating groove 505, a middle regulating groove 506 and a lower regulating groove 507. Since the liquid level and heat exchange requirements of the material in the tank 1 are usually distributed differently, the traditional integral jacket is difficult to match the actual heat transfer requirements evenly, which can easily cause local overheating or insufficient heating.

[0034] Specifically, the device body is divided into sections, allowing the upper regulating tank 505, the middle regulating tank 506 and the lower regulating tank 507 to receive steam supply independently. The heating intensity of a certain section can be flexibly started, stopped or adjusted according to the actual working conditions, which effectively improves temperature control, avoids energy waste, reduces equipment fatigue caused by temperature difference stress, and extends the service life of the extraction tank.

[0035] Pressure and temperature sensors are installed in the upper regulating tank 505, the middle regulating tank 506 and the lower regulating tank 507, and are arranged downstream of the steam inlet and at the middle height of the side wall. This can accurately reflect the real steam pressure and temperature state inside the jacket in this section. This arrangement avoids the areas where air bubbles easily accumulate at the top and condensate easily accumulates at the bottom, ensuring the stability and reliability of the sensor data.

[0036] The pressure sensor uses a piezoresistive or capacitive pressure transmitter, such as the German WIKA A-10 series or the American Rosemount 3051 series, to ensure rapid and accurate monitoring of steam pressure. The temperature sensor uses an industrial-grade platinum resistance thermometer, such as products from German JUMO or American Omega.

[0037] Furthermore, the combination of the sensing module 7 and the partitioned jacket structure enables closed-loop intelligent control of the steam heating process. The device body can dynamically adjust the opening of the regulating valve on the corresponding diversion pipe 504 based on the pressure and temperature parameters collected in real time in each area, thereby controlling the steam flow and pressure entering each section of the jacket and achieving on-demand heating. This partitioned monitoring and linkage adjustment mechanism significantly improves heating efficiency and process stability, and is especially suitable for temperature-sensitive extraction processes. It helps to improve the consistency of product quality, reduce the defect rate, and also enhances the equipment's adaptability to different production tasks.

[0038] Steam guide pipe 503 is the main pipeline, used to distribute the total amount of steam generated by the steam generator to each branch pipe 504.

[0039] like Figures 1-2 As shown, several material temperature sensors 8 are evenly distributed vertically on the inner circumference of the tank body 1. The bottom pipe of the tank body 1 is connected to the discharge pipe 3. The outer wall of the discharge pipe 3 is equipped with a valve for controlling the discharge of materials. The top pipe of the tank body 1 is connected to the inlet pipe 4. Several support feet 22 are fixedly connected to the bottom of the tank body 1. The bottom of the support feet 22 is covered with protective pads.

[0040] It should be noted that several material temperature sensors 8, evenly distributed vertically along the inner circumference of the tank 1, can monitor the material temperature at different heights within the tank in real time. This allows for the construction of a temperature field distribution of the material, enabling operators or the control system to accurately assess the uniformity of heating within the tank. This prevents extraction from being affected by excessively high or low local temperatures. Especially for heat-sensitive materials, this effectively prevents overheating decomposition or incomplete extraction, improving the controllability of the process and the stability of product quality.

[0041] For example, at least three material temperature sensors 8 are evenly distributed along the vertical direction of the tank body 1, located at 1 / 4, 1 / 2 and 3 / 4 of the height above the bottom of the tank body 1, respectively;

[0042] Among them, the discharge pipe 3 at the bottom of the tank 1, together with the control valve, realizes the regulation of the material discharge process after the extraction is completed. The valve is usually an electric ball valve, which has good sealing and corrosion resistance. It can not only prevent leakage and pollution, but also quickly and thoroughly discharge the material in the tank, reduce residue, and facilitate subsequent cleaning and the next batch of production. The inlet pipe 4 at the top of the tank 1 provides a convenient channel for the input of the material to be extracted and the solvent.

[0043] The support feet 2 and the protective pads at the bottom not only provide a support structure for the main body of the device, ensuring the stability and safety of the equipment during material loading and high-temperature and high-pressure operation, but also effectively reduce the wear and tear on the ground, as well as vibration and noise during operation, thus extending the service life of the equipment.

[0044] In use, the material to be extracted and the solvent are added to the tank 1 through the inlet pipe 4 at the top of the tank 1 and then closed. The gas steam generator is started to generate steam, which is introduced into the distribution pipe 504 system through the steam guide pipe 503. The initial steam flow rate of the upper, middle and lower regulating tanks 507 is set according to the material characteristics and process requirements. The feedback data of the pressure sensor and temperature sensor of each section is monitored by the sensing module 7, and the opening of the regulating valve on the corresponding distribution pipe 504 is dynamically adjusted according to the monitoring data to achieve on-demand heating. The upper regulating tank 505 heats the material in the upper part of the tank 1 to avoid overheating, the middle regulating tank 506 heats the main area of ​​the material to ensure uniform heating, and the lower regulating tank 507 heats the material at the bottom of the tank 1 to prevent the bottom from being too cold.

[0045] The material temperature sensor 8, which monitors the material temperature vertically distributed on the inner wall of the tank 1 in real time, constructs the material temperature field distribution to ensure that the material temperature is within the process requirements and avoids local overheating or undercooling. The steam supply intensity of each section is adjusted in a timely manner according to the temperature field distribution. At the same time, the pressure sensor monitors the pressure in each section jacket to ensure that the pressure is within the safe range. When the material extraction meets the process requirements, the gas steam generator is turned off, and the tank 1 is kept still for a period of time to ensure that the material is fully extracted. Then, the control valve on the outer wall of the discharge pipe 3 is opened to discharge the extracted material through the discharge pipe 3. After the discharge is completed, the valve of the discharge pipe 3 is closed.

[0046] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
