Description

Technical Field

[0001] This utility model relates to the field of ferulic acid extraction and processing technology, and in particular to a ferulic acid extraction container with temperature control. Background Technology

[0002] In the field of modern Chinese medicine extraction and natural product separation, ferulic acid is an important medicinal component. Its extraction efficiency is closely related to the accuracy of temperature control. With the advancement of modern Chinese medicine production, the shortcomings of traditional extraction processes in terms of temperature stability and energy efficiency have become increasingly prominent. In particular, in the process of large-scale industrial extraction, how to achieve precise temperature control while reducing energy consumption has become a key technical challenge to improve the extraction quality and economic benefits of ferulic acid.

[0003] Currently, the commonly used industrial ferulic acid extraction equipment mainly adopts a jacketed heating structure, which heats the reaction vessel by steam or electric heating rods. Temperature control is mostly achieved by simple on / off regulation, relying on temperature sensors and relays to control the start and stop of heating elements. The heat circulation system generally adopts a direct exhaust design, with the cooled heat medium being directly discharged or treated through a cooling tower.

[0004] Existing extraction equipment has deficiencies in temperature stability. Due to the lack of effective heat recovery and temperature control mechanisms, the temperature fluctuation range of the reactor is too large during long-term extraction, resulting in significant differences in the dissolution rate of ferulic acid. Traditional equipment directly discharges a large amount of cooling heat medium, resulting in heat energy waste. This not only increases production costs but also increases the impurity content in the extract due to temperature fluctuations, directly affecting the purity and yield of the final product. Therefore, a ferulic acid extraction container with temperature control is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a ferulic acid extraction container with temperature control, which aims to improve the problem that the temperature fluctuation range of the reaction vessel is too large during long-term extraction due to the lack of an effective heat recovery and temperature control mechanism, resulting in large differences in the dissolution rate of ferulic acid.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature-controlled ferulic acid extraction container, comprising a reaction vessel, an inlet and an outlet fixedly connected to the inner wall of the reaction vessel, a filter plate disposed inside the outlet, a motor disposed above the reaction vessel, a connecting rod fixedly connected to the output end of the motor, a plurality of stirring rollers fixedly connected to the outer wall of the connecting rod, a heating jacket fixedly connected to the outer wall of the reaction vessel, and a heating assembly disposed on the inner wall of the heating jacket; The heating assembly includes a heating tube and a water pump. The outer wall of the heating tube is fixedly connected to the inner wall of the heating sleeve. The output end of the water pump is fixedly connected to one end of the heating tube. The other end of the heating tube is fixedly connected to a processing box. A reflux assembly is provided on the inner wall of the processing box.

[0007] Furthermore, the reflux assembly includes a connecting pipe, a second water pump, and a reflux pipe. One end of the connecting pipe is fixedly connected to the inner wall of the processing tank, the input end of the second water pump is fixedly connected to the other end of the connecting pipe, one end of the reflux pipe is fixedly connected to the output end of the second water pump, and the other end of the reflux pipe is fixedly connected to the inner wall of the heating pipe. A diversion pipe is fixedly connected to the inner wall of the heating pipe, one end of the diversion pipe is fixedly connected to the inner wall of the processing tank, a heating block is provided on the outer wall of the reflux pipe, and a heating wire is provided on the inner wall of the heating block.

[0008] Furthermore, a fixing block is fixedly connected to the outer wall of the discharge port, and a connecting block is slidably connected to the inner wall of the fixing block.

[0009] Furthermore, the connecting block is attached to the outer wall of the filter plate, and the outer wall of the filter plate is slidably connected to the inner wall of the fixing block.

[0010] Furthermore, the outer wall of the connecting block one is fixedly connected to a handle and a fixing block two, and the inner wall of the fixing block two is slidably connected to a clamping block that is symmetrically positioned above and below.

[0011] Furthermore, the outer wall of the clamping block is slidably connected to the inner wall of the connecting block two, and the connecting block two is attached to the outer wall of the discharge port.

[0012] Furthermore, a button is slidably connected to the inner wall of the second connecting block, the lower end of the button is fixedly connected to the outer wall of the clamping block, and a second connecting rod is rotatably connected to the inner wall of the clamping block, the outer wall of the second connecting rod being fixedly connected to the inner wall of the second connecting block.

[0013] Furthermore, a telescopic rod and a spring are fixedly connected to the outer wall of the clamping block, and the spring is sleeved on the outer wall of the telescopic rod.

[0014] This utility model has the following beneficial effects: In this invention, heat energy is transferred to the reaction vessel through a heating tube, and temperature changes are monitored in real time by a sensor. When the temperature drops, the high-temperature hot water in the heating tube is diverted to the processing tank for initial heating via a diversion pipe, and then transported to the return pipe by a second water pump. After secondary heating by the heating wire in the heating block, it is returned to the heating tube. This design not only stabilizes the temperature in the reaction vessel within a suitable extraction range, ensuring the full dissolution of ferulic acid, but also reduces heat waste and lowers extraction costs through waste heat recovery.

[0015] In this invention, the filter plate can be disassembled simply by pressing a button. The clamping block rotates and squeezes the telescopic rod and spring, which releases the restriction on the second fixing block. Pulling the handle allows the filter plate to be removed from the first fixing block. The entire process requires no tools. After releasing the button, the spring and telescopic rod cause the clamping block to automatically reset, ensuring accurate positioning during reinstallation. This design facilitates timely cleaning of residual raw material residue on the filter plate, preventing impurities from accumulating and affecting subsequent filtration effects, ensuring the purity of the extract. It also makes it easy to replace filter plates with different pore sizes according to the characteristics of the raw materials, improving the adaptability and maintenance efficiency of the device.

[0019] Reference Figures 1-4 This utility model provides an embodiment of a ferulic acid extraction container with temperature control, comprising a reaction vessel 1. The inner wall of the reaction vessel 1 is fixedly connected to an inlet 2 and an outlet 9. A filter plate 20 is provided inside the outlet 9. The filter plate 20 filters the mixed raw materials discharged through the outlet 9, separates the raw material residue, and obtains an extract containing ferulic acid. A motor 3 is provided above the reaction vessel 1. A connecting rod 14 is fixedly connected to the output end of the motor 3. Multiple stirring rollers 15 are fixedly connected to the outer wall of the connecting rod 14. The stirring rollers 15 rotate under the drive of the connecting rod 14 to stir the raw materials and solvent in the reaction vessel 1, so that the two are fully mixed and the solvent is evenly penetrated into the raw material tissue. A heating jacket 8 is fixedly connected to the outer wall of the reaction vessel 1. The heating jacket 8 wraps around the outside of the reaction vessel 1 and has a heating tube 5 installed inside, which plays the role of heat preservation and centralized heat transfer, reducing heat loss and improving heating efficiency. A heating component is provided on the inner wall of the heating jacket 8. The heating assembly includes a heating tube 5 and a water pump 6. The outer wall of the heating tube 5 is fixedly connected to the inner wall of the heating jacket 8. The output end of the water pump 6 is fixedly connected to one end of the heating tube 5. The heating tube 5 receives hot water delivered by the water pump 6 and hot water returned by the return pipe 4, and heats the inside of the reactor 1 through heat transfer to maintain the required extraction temperature. The other end of the heating tube 5 is fixedly connected to a processing tank 7. The processing tank 7 receives the hot water in the heating tube 5 that has cooled down and performs preliminary heating on it. At the same time, it works with the diversion pipe 27 to realize the recycling of high-temperature hot water, which plays a role in preheating and temporary storage. The inner wall of the processing tank 7 is provided with a return assembly, which includes a connecting pipe 12, a water pump 10, and a return pipe 4. One end of the 2 is fixedly connected to the inner wall of the treatment tank 7. The input end of the second water pump 10 is fixedly connected to the other end of the connecting pipe 12. One end of the return pipe 4 is fixedly connected to the output end of the second water pump 10. The return pipe 4 is used to transport the hot water that has been heated twice and send the hot water heated by the heating block 11 back to the heating pipe 5 to form a hot water circulation and realize automatic heat recovery. The other end of the return pipe 4 is fixedly connected to the inner wall of the heating pipe 5. A diversion pipe 27 is fixedly connected to the inner wall of the heating pipe 5. One end of the diversion pipe 27 is fixedly connected to the inner wall of the treatment tank 7. A heating block 11 is provided on the outer wall of the return pipe 4. A heating wire 13 is provided on the inner wall of the heating block 11. The heating wire 13 reheats the hot water in the return pipe 4 to increase the hot water temperature.

[0020] Specifically, the feed inlet 2 on the inner wall of the reactor 1 is used to feed raw materials and solvents, and the filter plate 20 in the discharge port 9 can filter the mixed raw materials and separate the residues to obtain an extract containing ferulic acid. The motor 3 above the reactor 1 drives multiple stirring rollers 15 to rotate through the connecting rod 14, so that the raw materials and solvents are fully mixed and the solvent is uniformly penetrated. The heating jacket 8 on the outer wall of the reactor 1 plays a role in heat preservation. The heating tube 5 inside receives hot water delivered by the water pump 6 to heat the reactor 1. The heating tube 5 is connected to the processing tank 7. The diversion pipe 27 diverts the high-temperature hot water in the heating tube 5 to the processing tank 7 for initial heating, and then sends it to the return pipe 4 through the water pump 10 and the connecting pipe 12. After secondary heating by the heating wire 13 in the heating block 11, it is returned to the heating tube 5 to form a cycle, realizing precise temperature control and waste heat utilization, and improving the dissolution efficiency of ferulic acid.

[0021] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 A fixing block 16 is fixedly connected to the outer wall of the discharge port 9. The fixing block 16 provides installation and sliding space for the connecting block 17 and the filter plate 20, restricting their sliding trajectory and ensuring that the filter plate 20 is stably installed in the discharge port 9. The inner wall of the fixing block 16 is slidably connected to the connecting block 17, which fits against the outer wall of the filter plate 20. The outer wall of the filter plate 20 is slidably connected to the inner wall of the fixing block 16. The outer wall of the connecting block 17 is fixedly connected to the fixing block 19. The fixing block 19 cooperates with the clamping block 21. The limiting action of the clamping block 21 fixes the filter plate 20, ensuring that the filter plate 20 does not shake during filtration. The inner wall of the fixing block 19 is slidably connected to the upper and lower symmetrical clamping blocks 21. The clamping blocks 21 rotate about the connecting rod 24 as the center. Under normal conditions, they limit the fixing block 19 and fix the filter plate 20; when rotating, they release the limit. For easy disassembly of the filter plate 20, the outer wall of the clamping block 21 is slidably connected to the inner wall of the connecting block 22. The connecting block 22 is attached to the outer wall of the discharge port 9. A button 23 is slidably connected to the inner wall of the connecting block 22. The lower end of the button 23 is fixedly connected to the outer wall of the clamping block 21. A connecting rod 24 is rotatably connected to the inner wall of the clamping block 21. The connecting rod 24 serves as the rotation fulcrum of the clamping block 21, limiting the rotation trajectory of the clamping block 21 and ensuring that the clamping block 21 can rotate stably to limit or release the limit on the fixed block 29. The outer wall of the connecting rod 24 is fixedly connected to the inner wall of the connecting block 22. A telescopic rod 25 and a spring 26 are fixedly connected to the outer wall of the clamping block 21. The telescopic rod 25 and the spring 26 cooperate to be squeezed and contracted when the clamping block 21 rotates. After the button 23 is released, it extends back with the spring 26, assisting the clamping block 21 to automatically reset. The spring 26 is sleeved on the outer wall of the telescopic rod 25.

[0022] Specifically, the fixing block 16 on the outer wall of the outlet 9 provides installation space for the connecting block 17 and the filter plate 20. The connecting block 17 connects the filter plate 20 to the handle 18. The fixing block 29 on it cooperates with the symmetrical clamping blocks 21 to fix the filter plate 20. Pressing the button 23 inside the connecting block 22 causes the clamping block 21 to rotate around the connecting rod 24, squeezing the telescopic rod 25 and the spring 26, releasing the limitation on the fixing block 29. Pulling the handle 18 allows the filter plate 20 to be removed. After releasing the button 23, the spring 26 and the telescopic rod 25 drive the clamping block 21 to reset, realizing the quick disassembly and assembly of the filter plate 20, which is convenient for cleaning or replacing filter plates 20 with different pore sizes, and ensuring the purity of the extract.

[0023] Working principle: When extracting ferulic acid, the crushed raw material and solvent are first put into the reaction vessel 1 through the feed port 2. The water pump 6 is started to deliver hot water to the heating tube 5 in the heating jacket 8. The internal part of the reaction vessel 1 is heated by heat transfer. At the same time, the motor 3 is started to drive the connecting rod 14 to rotate multiple stirring rollers 15, so that the raw material and solvent are fully mixed and the solvent is evenly penetrated into the raw material tissue. When the sensor in the reactor 1 detects a temperature drop, the hot water in the heating tube 5, which has cooled down, flows into the processing tank 7. At this time, the diversion pipe 27 diverts the water flow in the heating tube 5 and delivers the high-temperature hot water to the processing tank 7 for initial heating. Then, the water pump 10 is started to send the initially heated hot water through the connecting pipe 12 into the return pipe 4. The water is then heated again by the heating wire 13 in the heating block 11 on the outer wall of the return pipe 4, and then sent back to the heating tube 5 through the return pipe 4, thus realizing automatic heat recovery and waste heat recycling. When the mixed raw materials pass through the discharge port 9, they are filtered by the filter plate 20 and discharged. If it is necessary to disassemble, clean or replace the filter plate 20, press the button 23 to make it slide in the connecting block 22, which will drive the upper and lower symmetrical clamping blocks 21 to rotate around the connecting rod 24 as the center, squeezing the telescopic rod 25 and the spring 26, so that the fixing block 29 fixed on the connecting block 17 is disengaged from the limit of the clamping block 21. Then pull the handle 18 to drive the connecting block 17 and the filter plate 20 to slide out from the fixing block 16. After releasing the button 23, the squeezed telescopic rod 25 and the spring 26 will drive the clamping block 21 to automatically reset, which is convenient for the next installation and fixation.
