Description

Technical Field

[0001] This utility model relates to the field of chemical engineering technology, and more specifically, to an extraction and separation device for chemical engineering. Background Technology

[0002] In the field of chemical engineering, the need to separate mixed solvents is frequent, and extraction, as a key separation technology, is widely used in such scenarios. Extraction, also known as solvent extraction or liquid-liquid extraction, is based on the difference in solubility or partition coefficient of a substance in two immiscible solvents, to achieve the efficient transfer of a solute from one solvent to another.

[0003] Because impurities tend to accumulate in the central area of ​​the filter plate, the flow rate of the solution on both sides is significantly reduced. This uneven fluid distribution not only affects filtration efficiency but can also lead to instability in the entire system. While the V-shaped filter plate was originally designed to increase filtration area and efficiency, if impurities concentrate in the center, the space on both sides of the filter plate is not fully utilized, thus limiting overall filtration efficiency. Severe impurity accumulation significantly impacts filtration performance, leading to a decrease in the purity of the final product. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an extraction and separation device for chemical engineering.

[0005] An extraction and separation device for chemical engineering includes a fixed frame, an extraction cylinder, a feed pipe, a servo motor, a stirring rod, a vibrating motor, a connecting frame, a sieve plate, and a guide plate. The extraction cylinder is connected to the fixed frame, and the feed pipe is connected to the extraction cylinder. The servo motor is installed at the top of the extraction cylinder, and the output shaft of the servo motor extends into the extraction cylinder. The stirring rod is rotatably connected inside the extraction cylinder and is fixedly connected to the output shaft of the servo motor. The connecting frame, the vibrating motor, and the guide plate are connected to the bottom of the extraction cylinder, and the sieve plate is connected inside the connecting frame.

[0006] Furthermore, the top of the guide plate is smaller than the bottom.

[0007] Furthermore, it also includes a scraper, a handle, and a fixing frame. The right side of the connecting frame has a through hole, and the right side of the connecting frame is connected to the fixing frame. The scraper is slidably connected inside the connecting frame, and the side of the scraper away from the connecting frame is connected to the handle.

[0008] Furthermore, it also includes a sealing strip, with the sealing strip connected to the side of the scraper closest to the fixed frame.

[0009] Furthermore, it also includes a collection box, which is slidably connected within the fixed frame.

[0010] Furthermore, it also includes a retaining bead and a connecting spring. The retaining bead is slidably connected to the side of the scraper block near the fixed frame.

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] An extraction and separation device for chemical engineering, such as Figures 1-4As shown, the system includes a fixed frame 1, an extraction cylinder 2, a feed pipe 3, a servo motor 4, a stirring rod 5, a vibration motor 6, a connecting frame 7, a sieve plate 8, a guide plate 9, a scraper 10, a handle 11, a fixed frame 15, a sealing strip 14, a collection frame 16, a retaining bead 12, and a connecting spring 13. The extraction cylinder 2 is fixedly connected to the top of the fixed frame 1. The feed pipe 3 is fixedly connected to the top of the extraction cylinder 2. The servo motor 4 is mounted on the top of the extraction cylinder 2, and its output shaft extends into the extraction cylinder 2. The stirring rod 5 is rotatably connected inside the extraction cylinder 2 and is fixedly connected to the output shaft of the servo motor 4. The connecting frame 7, the vibration motor 6, and the guide plate 9 are fixedly connected to the bottom of the extraction cylinder 2. The top of the guide plate 9 is smaller than its bottom, and the guide plate 9 can disperse the solvent falling from the extraction cylinder 2, preventing localized accumulation caused by direct concentrated solvent fall. To prevent accumulation or blockage, and to ensure smooth and uniform solvent flow, the vibration motor 6 accelerates the flow of solvent from the extraction cylinder 2, preventing solvent from stagnating at the bottom of the extraction cylinder 2. A sieve plate 8 is fixedly connected inside the connecting frame 7. A through hole is opened on the right side of the connecting frame 7. A fixed frame 15 is fixedly connected to the right side of the connecting frame 7. A scraper 10 is slidably connected inside the connecting frame 7. A handle 11 is fixedly connected to the side of the scraper 10 away from the connecting frame 7. A sealing strip 14 is fixedly connected to the side of the scraper 10 near the fixed frame 15. The sealing strip 14 can improve the sealing between the scraper 10 and the through hole. A collection frame 16 is slidably connected inside the fixed frame 15. A retaining bead 12 is slidably connected to the side of the scraper 10 near the fixed frame 15. A connecting spring 13 is fixedly connected between the retaining bead 12 and the scraper 10. The retaining bead 12 is engaged with the connecting frame 7.

[0019] When using this separation device, the mixed solvent is poured into the extraction cylinder 2 through the feed pipe 3. The stirring rod 5 is driven to rotate by the servo motor 4 to improve the extraction efficiency and enhance the purity and quality of the final product. The separated solvent flows out from the bottom of the extraction cylinder 2 and falls onto the guide plate 9. The separated solvent then flows downward along the slope of the guide plate 9 and falls onto the sieve plate 8. The separated solvent is filtered through the sieve plate 8, and the filtered solvent flows out through the sieve holes of the sieve plate 8. Large particles of impurities are retained on the sieve plate 8, which ensures the purity and quality of the solvent. Finally, the filtered solvent flows out from the bottom of the connecting frame 7 and is then collected. When it is necessary to clean the large particles of impurities on the sieve plate 8, the scraper 10 is pulled by the handle 11, causing the scraper 10 to move to the right and scrape off the large particles of impurities on the sieve plate 8. The retaining bead 12 is squeezed into the scraper 10, and the connecting spring 13 is compressed to remove the large particles of impurities. Large particles of impurities accumulated on the sieve plate 8 are removed to ensure its continuous and effective operation, maintain its expected filtration performance, prevent clogging and reduce filtration efficiency, and extend its service life. The scraper 10 moves the large particles of impurities to the right through the through hole and into the collection frame 16, thus cleaning the sieve plate 8. Then, the handle 11 moves the scraper 10 in the opposite direction into the connecting frame 7, and the connecting spring 13 returns to its original position, causing the retaining bead 12 to engage with the connecting frame 7. Under the elastic force of the connecting spring 13, the retaining bead 12 increases the friction of the scraper 10, preventing it from sliding freely. When it is necessary to clean the large particles of impurities in the collection frame 16, slide the collection frame 16 to the right to disengage it from the fixed frame 15, and then clean the collection frame 16. After cleaning, slide the collection frame 16 back into the fixed frame 15.
