Description

Technical Field

[0001] This utility model relates to the field of chemical reagent preparation technology, specifically to an extraction device for preparing chemical reagents. Background Technology

[0002] Chemical reagents are substances used in chemical experiments and research for chemical reactions, analysis, and detection. They are typically high-purity chemical substances, specific to particular experiments or applications, and possess well-defined chemical properties. Chemical reagents can be classified according to their uses and properties, and are widely used in various fields such as chemistry, biology, pharmacy, environmental science, and materials science. During the synthesis of chemical reagents, impurities or impure byproducts may be generated. Extraction can separate the target compound from the mixture, thereby improving its purity.

[0003] Chinese Patent No. CN220554684U discloses an extraction device for preparing chemical reagents. It includes a reaction vessel for reagent reaction preparation, with a placement groove at the bottom center of the reaction vessel, and a filter plate for chemical reagent filtration and extraction installed inside the placement groove. By setting up components such as the reaction vessel, placement groove, filter plate, filter screen, and holder, it is convenient for the reaction vessel to react with the reagents inside, so as to facilitate the filtration and extraction of chemical reagents.

[0004] Regarding the aforementioned technologies, this equipment has some shortcomings. In actual use, the sealing cover is fixed to the top of the reaction vessel with bolts. Disassembling the bolts requires specialized tools and is relatively cumbersome, increasing the time required for cleaning and maintenance. Furthermore, after repeated disassembly and use, the bolts may rust, wear, or deform, leading to a decrease in sealing performance during subsequent reinstallation, thus affecting the safety and reliability of the equipment. During the disassembly process, operators must exercise extreme caution to prevent accidental injury or damage to the equipment, which to some extent limits work efficiency and ease of use. Therefore, it is necessary to provide an extraction device for chemical reagent preparation to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an extraction device for preparing chemical reagents to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An extraction apparatus for preparing chemical reagents, comprising:

[0008] The support frame consists of two supports, each with a fixed frame fixedly installed below the opposite sides. A reaction vessel is fixedly installed on the top of the fixed frame, and several drip pipes with valves are fixedly installed at the bottom of the reaction vessel. A cover plate is installed on the top of the reaction vessel, and a feed pipe is fixedly inserted into one side of the top of the cover plate. Limit grooves are provided on both supports.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 One embodiment provided by this utility model:

[0029] An extraction apparatus for preparing chemical reagents, comprising:

[0030] Support frame 1, there are two support frames 1, and a fixed frame 14 is fixedly installed on the lower side of the two support frames 1. The reaction vessel 2 is fixedly installed on the top of the fixed frame 14. Several drip pipes 3 are fixedly installed on the bottom of the reaction vessel 2, and valves are provided on the drip pipes 3. The top of the reaction vessel 2 is provided with a cover plate 7. A feed pipe 9 is fixedly inserted on one side of the top of the cover plate 7. Limit grooves 5 are opened on both support frames 1.

[0031] Both limiting through grooves 5 are rotatably installed with threaded rods 11. The top of the support frame 1 is fixedly installed with a first motor 6, and the drive end of the first motor 6 passes through the top of the support frame 1 and extends into the inside of the limiting through groove 5 and is fixedly connected to the top of the threaded rod 11. Adjusting blocks 10 are threadedly sleeved on the outer walls of both threaded rods 11, and the adjusting blocks 10 are slidably connected to the limiting through groove 5.

[0032] A connecting frame 4 is fixedly installed on each of the two adjusting blocks 10 on opposite sides, and the end of the connecting frame 4 away from the adjusting block 10 is fixedly connected to the cover plate 7. A stirring mechanism is provided on the cover plate 7, and a filtration mechanism is provided inside the reaction tank 2.

[0033] The stirring mechanism includes a second motor 8, which is fixedly installed on the top of the cover plate 7. The driving end of the second motor 8 passes through the bottom of the cover plate 7 and extends to the bottom of the cover plate 7. A first stirring shaft 15 is fixedly installed on the driving end of the second motor 8. Several first transverse stirring rods 16 are fixedly installed on the outer wall of the first stirring shaft 15.

[0034] In one embodiment, the filtration mechanism includes a filter plate 12, which is disposed inside the reaction vessel 2. An annular seal 22 is fixedly installed at the lower part of the reaction vessel 2, and the filter plate 12 is disposed on the top of the annular seal 22. A plurality of filter screens 13 are fixedly installed on the filter plate 12. A plurality of connecting rods 19 are fixedly installed on the outer side of the bottom of the cover plate 7, and the bottom end of the connecting rods 19 is fixedly connected to the top of the filter plate 12 by bolts. The annular seal 22 ensures the sealing of the filter plate 12 at its installation position inside the reaction vessel 2.

[0035] In one preferred embodiment, a second stirring shaft 17 is rotatably mounted on the top of the filter plate 12, and the bottom end of the second stirring shaft 17 passes through the top of the filter plate 12 and extends to the bottom of the filter plate 12. Several second transverse stirring rods 18 are fixedly mounted on the outer wall of the second stirring shaft 17. A rectangular connecting post 21 is fixedly mounted on the bottom end of the first stirring shaft 15. A connecting groove 20 is opened at the top end of the second stirring shaft 17, and the connecting groove 20 is engaged with the rectangular connecting post 21, thereby achieving a stirring effect on the area below the filter plate 12. At the same time, the rotation of the second stirring shaft 17 and the rotation of the first stirring shaft 15 share a common drive source, which greatly reduces the operating cost of the equipment and improves the economy of the equipment.

[0036] In one embodiment, the filter screen 13 is bowl-shaped, which can capture impurities in the reaction liquid over a large area, avoiding the local blockage caused by traditional planar filters.

[0037] In one preferred embodiment, the connection between the cover plate 7 and the reaction vessel 2 is stepped, and a sealing gasket is provided at the connection between the cover plate 7 and the reaction vessel 2. This stepped connection not only enhances the mechanical strength and stability of the connection, but also allows for more precise alignment of the cover plate 7 and the reaction vessel 2, reducing deviations during installation. The sealing gasket also improves the overall sealing performance of the equipment.

[0038] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer for control, and existing publicly available power connection technologies are not detailed here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. In use, chemical reagents are added to the interior of the reaction vessel 2 through the feed pipe 9, and then the second motor 8 is started. The drive end of the second motor 8 drives the first stirring shaft 15 to rotate, and the rotation of the first stirring shaft 15 drives the first transverse stirring rod 16 to rotate. The rotation of the stirring rod 16 agitates the chemical reagents inside the reaction vessel 2. When the reagents pass through the filtration mechanism at the bottom of the reaction vessel 2, the filter screen 13 on the filter plate 12 filters them, improving the extraction quality. Subsequently, the reagents are extracted and discharged through multiple drip pipes 3 at the bottom of the reaction vessel 2. After use, the equipment needs to be cleaned internally to ensure stable operation. The two first motors 6 can be directly controlled to start working. Encoders are installed on the two first motors 6 to measure their speed and position. The controller is used to adjust the speed and position of the first motor 6 to maintain synchronization. The rotation of the drive end of the first motor 6 drives the threaded rod 11 to rotate. The synchronous rotation of the two threaded rods 11, through the threaded transmission between the threaded rods 11 and the adjusting block 10, and the sliding relationship between the adjusting block 10 and the limiting groove 5, enables the two adjusting blocks 10 to move stably and synchronously vertically. The movement of the adjusting block 10 drives the connecting frame 4 to move, and the connecting frame 4 drives the cover plate 7 to move upward, so that the cover plate 7 automatically detaches from the top of the reaction tank 2. The movement of the reaction tank 2 will drive the stirring mechanism and the filtration mechanism to move upward together, so that the stirring mechanism and the filtration mechanism can move upward together. The filtration mechanism is moved directly out of the interior of the reaction tank 2, so that as the cover plate 7 automatically separates from the reaction tank 2, the components inside the reaction tank 2 are also moved out. This completely exposes the internal structure of the reaction tank 2, allowing staff to easily access the tank and internal components, thus enabling them to quickly and efficiently complete cleaning, inspection, and maintenance. Compared to fixing the cover plate 7 with bolts, the mechanical drive method not only eliminates the various inconveniences and potential problems caused by bolt fixing, but also significantly improves the operability and maintenance efficiency of the equipment, making the daily use of the equipment simpler, more efficient, and safer.

[0039] During use, the device is connected to the cover plate 7 via the connecting rod 19, and the filter plate 12 is fixed to the connecting rod 19 with bolts. Therefore, the filter plate 12 is detachable from the connecting rod 19. When the filter mechanism is moved out of the reaction tank 2 along with the cover plate 7, it can be disassembled to facilitate the cleaning and maintenance of the filter screen 13. In addition, during the installation of the filter plate 12 at the bottom of the connecting rod 19, the second stirring shaft 17 located on the filter plate 12 is engaged with the rectangular connecting post 21 at the bottom of the first stirring shaft 15 via the connecting groove 20 at its top. Thus, during the operation of the stirring mechanism, the rotation of the first stirring shaft 15 will drive the second stirring shaft 17 to rotate through the rectangular connecting post 21. The rotation of the second stirring shaft 17 will drive the second transverse stirring rod 18 to rotate. The rotation of the second transverse stirring rod 18 can stir the chemical reagents located below the filter plate 12 inside the reaction tank 2, ensuring sufficient stirring of the reagents inside the reaction tank 2, further improving the extraction quality of the chemical reagents, and making it highly practical.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
