Description

Technical Field

[0001] This application relates to the field of plant extraction and concentration technology, and more specifically, to an extraction and concentration device that prevents scaling. Background Technology

[0002] With the rapid development of chemical and pharmaceutical technologies, scaling in extraction and concentration equipment has become a key factor restricting the efficient operation of the industry. Currently, while existing extraction and concentration equipment on the market has mitigated scaling to some extent through optimized materials and design, significant defects and shortcomings remain. Particularly at the bottom of the reactor, scaling is particularly severe due to prolonged material deposition, seriously affecting the uniformity of material mixing and frequently leading to shutdowns for cleaning, thus severely impacting production efficiency and product quality. Therefore, existing technologies are clearly insufficient in ensuring continuous, efficient production and stable product quality, limiting their widespread application in fine chemicals, biopharmaceuticals, and other related fields. In view of this, developing an extraction and concentration device that can effectively prevent scaling at the bottom of the reactor to solve the scaling problem in existing technologies is of great significance for improving production efficiency, ensuring product quality, and promoting technological progress in related fields.

[0021] Please see Figure 1 This application provides an anti-scaling extraction and concentration device 100, which includes a mixing vessel 10 and a stirrer 20. The mixing vessel 10 is placed vertically. The mixing vessel 10 includes a vessel body 11, a conical discharge hopper 12, and a flexible connector 13. The conical discharge hopper 12 is located at the bottom end of the vessel body 11 and is connected to and sealed at the bottom end of the vessel body 11 by the flexible connector 13. The stirrer 20 includes a stirring assembly 30 and a brushing assembly 40. The stirring assembly 30 is coaxially installed inside the vessel body 11. The brushing assembly 40 includes a scraper 41 and a connecting shaft 42. The two ends of the connecting shaft 42 are respectively connected to the scraper 41 and the stirring assembly 30. The long side of the scraper 41 is inclined and corresponds to the inclined surface of the conical discharge hopper 12. When descaling is required, the inclined surface of the conical discharge hopper 12 is brought close to the inclined long side of the scraper 41, and the stirring assembly 30 drives the scraper 41 to rotate and scrape off the scale.

[0022] The extraction and concentration equipment 100 of this application effectively solves the problem of easy scaling at the bottom of the reaction vessel in the extraction and concentration equipment 100 by adopting the design of mixing vessel 10 and flexible connector 13, and the brush removal component 40 integrated with agitator 20. It achieves the technical effect of automatically scraping the scale on the inclined surface of conical discharge hopper 12 by a scraper 41 driven by agitator 30 without affecting normal production, which significantly improves the continuous operation capability and production efficiency of the equipment and greatly reduces the economic losses caused by shutdown for cleaning.

[0023] Specifically, please refer to Figure 1 and Figure 2 The mixing vessel 10 includes a vessel body 11, a conical discharge hopper 12, and a flexible connector 13. The vessel body 11 is cylindrical, with a feed funnel 111 at its upper end. The conical discharge hopper 12 is located at the bottom opening of the vessel body 11. The flexible connector 13 connects to and seals the bottom opening of the vessel body 11. The upper opening of the conical discharge hopper 12 corresponds to the lower opening of the vessel body 11 and is connected by the flexible connector 13. The conical discharge hopper 12 has an inclined surface that transitions to the discharge port. The flexible connector 13 can be made of rubber or other flexible materials and can be fixed to the vessel body 11 and the conical discharge hopper 12 by one or more methods such as adhesive, snap-fit, and screws. Due to the flexibility of the flexible connector, the conical discharge hopper 12 can move up and down.

[0024] The agitator 20 is coaxially installed inside the vessel body 11. The agitator 20 includes a stirring assembly 30 and a scraping assembly. The stirring assembly 30 includes a stirring element 31 and a mounting element 32. The stirring element 31 includes a rotating shaft 311, a stirring plate 312, a connecting rod 313, and a power mechanism 314. The mounting element 32 includes a rotating shaft seat 321 and a mounting rod 322. The scraping assembly 40 includes a scraper 41 and a connecting shaft 42.

[0025] The rotating shaft 311 is coaxially arranged with the vessel body 11. One end of the rotating shaft 311 extends through the upper end of the vessel body 11 and is connected to the power mechanism 314. A stirring plate 312 surrounds the outer circumference of the rotating shaft 311 at intervals. The stirring plate 312 is connected to the rotating shaft 311 via a connecting rod 313. One end of the connecting rod 313 is fixedly connected to the rotating shaft 311, and the other end is fixedly connected to the midpoint of one long side of the stirring plate 312. The connecting rod 313 is perpendicular to the rotating shaft 311. The other long side of the stirring plate 312 has an arc corresponding to the inner wall of the vessel body 11, and the radius of the arc is the same as the radius of the vessel body 11. Two stirring elements 31 are rotationally symmetrical along the central axis of the rotating shaft 311, forming a group. In the embodiment of this application, there are a total of 5 groups from bottom to top, with gaps between each group. The number of stirring elements 31 can be set as needed.

[0026] A rotating shaft seat 321 is fitted around the outer circumference of the rotating shaft 311, and is located in the gap between the first and second groups of stirring components 31 from bottom to top. There are four mounting rods 322, which are evenly spaced around the rotating shaft seat 321, with an included angle of 90 degrees between each pair of rods. One end of the mounting rod 322 can be fixedly connected to the rotating shaft seat 321 by welding, screw fixing, or other means, and the other end of the mounting rod 322 is fixed to the inner wall of the vessel body 11 by screws or other detachable means.

[0027] The brushing assembly 40 is located at the lower end of the rotating shaft 311. One end of the connecting rod 313 is fixedly installed at the lower end of the rotating shaft 311, and the other end of the connecting rod 313 is fixedly connected to the midpoint of one long side of the scraper 41. The other long side of the scraper 41 corresponds to the inclined transition surface of the conical discharge hopper 12, and the two have the same inclination angle. When the conical discharge hopper 12 moves upward, the scraper 41 can completely fit against the transition surface of the conical discharge hopper 12. The scraper 41 is made of hard plastic or rubber material, which can scrape off the mixture on the transition surface of the conical discharge hopper 12 while maintaining the ability to stir the mixture, thus preventing scale formation. There are two brushing assemblies 40, which are rotationally symmetrical about the central axis of the rotating shaft 311. In the embodiment of this application, the connecting shaft 42, the connecting rod 313, and the mounting rod 322 are all cylindrical rods, which can prevent scale formation to a certain extent.

[0028] The extraction and concentration equipment 100 also includes an ultrasonic generator 50, which is used to break up the mixed materials. The ultrasonic generator 50 is installed inside the vessel body 11, located between two adjacent sets of stirring components 30. In the embodiments of this application, the ultrasonic generator 50 is perpendicular to the inner wall of the vessel body 11, and two generators are symmetrically arranged along the central axis of the vessel body 11 to form a set. There are three sets from bottom to top, located between the second and third sets, the third and fourth sets, and the fourth and fifth sets of stirring components 31.

[0029] The extraction and concentration equipment 100 also includes a support 60, which is located on the outside of the vessel body 11 and supports the entire mixing vessel 10. A drive device 61 is mounted on the support 60, which pushes the conical discharge hopper 12 towards and away from the scraper 41. Specifically, a collar 121 is provided outside the conical discharge hopper 12. Two drive devices 61 are symmetrically arranged on both sides of the conical discharge hopper 12. The output shaft of the drive device 61 is connected to the collar 121. The two drive devices 61, connected to the collar 121, push the collar 121 up and down, thereby allowing the conical discharge hopper 12 to approach and contact the scraper 41. The drive device 61 has a limited range of movement to prevent excessive pushing of the conical discharge hopper 12. The drive device 61 can be a hydraulic telescopic cylinder, a motor, etc.

[0030] When it is necessary to remove scale, the drive device 61 pushes downward so that the conical discharge hopper 12 can contact the scraper 41. The scraper 41 rotates under the drive of the rotating shaft 311 to remove scale. When it is not necessary to remove scale, the drive device 61 retracts, and the conical discharge hopper 12 is separated from the scraper to form a certain distance. At the same time, the scraper 41 rotates under the drive of the rotating shaft 311 to mix the material.
