Description

Technical Field

[0001] The invention relates to the technical field of pharmaceutical equipment, and in particular to a fermentation liquid separation and extraction device. Background Art

[0002] With the increasing clinical demand for steroid drugs, the development of industrial production of steroid drugs has been promoted, and significant economic and social benefits have been achieved. Steroid drugs are mainly used to maintain human life activities, regulate body metabolism, promote the growth and development of sexual organs, etc. 9-Hydroxy-androstenedione is an important steroid drug intermediate. Its production method is mainly microbial transformation. Microbial transformation is a process in which enzymes produced by microbial metabolism are used as catalysts to produce another new substance through enzyme-induced reactions with specific parts or groups of the substrate. Its industrial production process mainly includes seed preparation, seed culture, transformation culture and fermentation broth separation and purification. In the process of fermentation broth separation and purification, a fermentation broth separation and extraction device is required to separate the target product from the fermentation broth.

[0003] The existing fermentation broth separation and extraction device usually first uses a plate and frame filter to perform efficient solid-liquid separation on the fermentation broth to obtain a filter cake containing the target product. Subsequently, these filter cakes are sent to an extraction tank, and a predetermined proportion of extractant is added thereto in order to achieve effective extraction of the target product. However, there are two key problems that need to be solved in this process. The first problem is that due to the relatively large volume of the filter cake, its specific surface area (i.e., the surface area per unit volume) is limited, which in turn affects the contact area between the filter cake and the extractant. This limitation directly leads to a reduction in extraction efficiency, because the extraction process depends to a large extent on the diffusion and dissolution of the solute at the interface between the two phases. Secondly, the filter cake tends to settle rapidly and accumulate at the bottom of the extraction tank under the action of its own gravity. In this process, the pore structure inside the filter cake may change, making it difficult for the extractant to penetrate into the filter cake, thereby further reducing the extraction efficiency. At the same time, due to design limitations, conventional stirring components often find it difficult to effectively stir up the material at the bottom of the extraction tank so that it can be fully mixed and reacted with the extractant. This not only affects the extraction effect, but also causes uneven distribution of materials in the extraction tank, further reducing the extraction efficiency of the fermentation liquid.

[0004] Therefore, it is necessary to develop a fermentation liquid separation and extraction device to address the above-mentioned defects. Summary of the invention

The driving member drives the rotating shaft 601 and the shaft cylinder 602 to rotate in the opposite direction, driving the rolling roller 603 and the sieve plate 604 to rotate in the opposite direction, and the rolling roller 603 rolls and crushes the material falling on the sieve plate 604, and then falls into the extraction tank 3 to mix with the extractant, thereby increasing the contact area between the material and the extractant, thereby accelerating the dissolution of the material in the extractant.

[0037] In a specific embodiment, Figure 1 and Figure 2As shown, the driving member includes a motor 605, a first bevel gear 606, a second bevel gear 607 and a third bevel gear 608; a shell 609 is fixedly connected to the tank cover of the extraction tank 3, a rotating shaft 601 and a shaft cylinder 602 both penetrate the bottom surface of the shell 609, the rotating shaft 601 is rotatably connected to the inner top surface of the shell 609, and the shaft cylinder 602 is rotatably connected to the bottom surface of the shell 609; the first bevel gear 606 is fixedly sleeved on the outer wall of the top end of the shaft cylinder 602, and the second bevel gear 607 is fixedly sleeved on the outer wall of the top end of the rotating shaft 601; the motor 605 is fixedly connected to the bracket 5, and the third bevel gear 608 is fixedly connected to the output end of the motor 605, and the third bevel gear 608 is meshed with the first bevel gear 606 and the second bevel gear 607 for transmission.

[0038] The motor 605 rotates to drive the third bevel gear 608 to rotate, and the third bevel gear 608 drives the first bevel gear 606 and the second bevel gear 607 to rotate in the opposite direction, thereby driving the crushing roller 603 and the sieve plate 604 to rotate in the opposite direction relative to each other, thereby achieving effective crushing of the material.

[0039] In a specific embodiment, Figure 6 and Figure 7 As shown, there are two rolling rollers 603, which are symmetrically arranged. Two scrapers 610 are arranged between the two rolling rollers 603. The two scrapers 610 are fixedly connected to the outer wall of the shaft tube 602, and the bottom surface of the scraper 610 is fixedly connected to a plurality of rake teeth 611 evenly distributed along its length.

[0040] The crushed materials on the screen plate 604 can be scraped and stirred by the scraper 610 and the rake teeth 611 .

[0041] Specifically, a plurality of annular grooves 612 corresponding to and matching the rake teeth 611 are spaced apart on the top surface of the sieve plate 604 , the bottom ends of the rake teeth 611 are slidably connected to the bottom surfaces of the annular grooves 612 , and a plurality of sieve holes 613 are formed on the bottom surface of the annular grooves 612 .

[0042] By providing the annular groove 612 and cooperating with the rake teeth 611, the material can be fully crushed and crushed, and the crushed material is transported to the extraction tank 3 through the sieve holes 613 to be mixed with the extractant.

[0043] Specifically, an arc-shaped protrusion 614 is fixedly connected to the inner bottom surface of the sieve plate 604, a limiting ring 615 is sleeved on the outer wall of the rotating shaft 601 below the sieve plate 604, a compression spring 616 is arranged between the limiting ring 615 and the sieve plate 604, one end of the compression spring 616 is fixedly connected to the bottom surface of the sieve plate 604, and the other end of the compression spring 616 is fixedly connected to the limiting ring 615; an axis groove 617 is opened on the rotating shaft 601, a guide flat key 618 is fixedly connected in the axis groove 617, and the sieve plate 604 is slidably connected to the guide flat key 618.

[0044] By setting the arc-shaped protrusion 614, during the relative movement between the sieve plate 604 and the rolling roller 603, when the rolling roller 603 passes through the arc-shaped protrusion 614, the sieve plate 604 will be squeezed, so that it moves downward along the rotating shaft 601 for a short distance and compresses the compression spring 616. After the rolling roller 603 passes through the arc-shaped protrusion 614, the sieve plate 604 is driven to move upward and return to its original position under the action of the restoring force of the compression spring 616. During the continuous rotation of the rolling roller 603 and the sieve plate 604, the sieve plate 604 moves up and down and generates vibration, thereby preventing the material from blocking the sieve hole 613 and increasing the material discharge speed.

[0045] In a specific embodiment, Figure 5 and Fig.11 As shown, the limiting member includes two sliding rods 11, the top ends of the two sliding rods 11 are fixedly connected to the inner wall of the extraction tank 3 through a mounting plate, the bottom ends of the sliding rods 11 are fixedly connected to the support frame 10, and the anti-sinking plate 8 is provided with sliding holes 12 corresponding to the sliding rods 11, and the anti-sinking plate 8 is slidably connected to the sliding rods 11 through the sliding holes 12; the anti-sinking plate 8 is provided with a plurality of guide holes 13.

[0046] The rotation of the rotating shaft 601 drives the threaded rod 7 to rotate, and the threaded connection between the anti-sinking plate 8 and the threaded rod 7 and the setting of the sliding rod 11 can drive the anti-sinking plate 8 to move up and down along the threaded rod 7. The guide hole 13 provided on the anti-sinking plate 8 can facilitate the extraction liquid to pass through the guide hole 13, reduce the resistance of the extraction liquid to the anti-sinking plate 8, and at the same time enhance the flow of the extraction agent in the fermentation tank, which is more conducive to the uniform mixing of the extraction agent and the material.

[0047] Specifically, if Figures 8 to 10 As shown, the stirring assembly 9 includes a first connecting ring 901 and a second connecting ring 902; a plurality of first stirring paddles 903 are fixedly connected to the outer wall of the first connecting ring 901, and a plurality of second stirring paddles 904 are fixedly connected to the outer wall of the second connecting ring 902; a plurality of connecting rods 905 are fixedly connected between the first connecting ring 901 and the second connecting ring 902, the first connecting ring 901 is rotatably connected to the anti-sinking plate 8, and a gap is set between the bottom surface of the first stirring paddle 903 and the top surface of the anti-sinking plate 8; the first connecting ring 901 and the second connecting ring 902 are slidably connected to the threaded rod 7.

[0048] The first stirring paddle 903 can be used to stir the material settled on the top surface of the anti-settling plate 8 so that it is redispersed in the extractant and mixed with the extractant. The second stirring paddle 904 can fully stir and mix the dispersant and the material. The first connecting ring 901 and the anti-settling plate 8 are rotatably connected, and the first connecting ring 901 and the second connecting ring 902 are connected by a connecting rod 905. The first stirring paddle 903 and the second stirring paddle 904 can move up and down on the threaded rod 7 following the anti-settling plate 8, and can stir the extractant at various positions of the extraction tank 3, so that the material is more evenly dispersed in the extract.

[0049] Specifically, a plane is provided on the outer wall of the threaded rod 7 along its length direction, and a slide groove 906 is provided on the plane. The first connecting ring 901 and the second connecting ring 902 are both slidably connected to the slide groove 906 via a sliding key 907 .

[0050] By providing the sliding groove 906 and the sliding key 907 , the first connecting ring 901 and the second connecting ring 902 can slide up and down on the threaded rod 7 and rotate along with the rotation of the threaded rod 7 , thereby achieving stirring of the extraction liquid.

[0051] In a specific embodiment, Figure 3 and Figure 5 As shown, a liquid adding port 14 is opened and fixedly connected on the outer wall of the extraction tank 3 to facilitate adding the extracting agent into the extraction tank 3.

[0052] In a specific embodiment, the tank cover and the tank bottom of the extraction tank 3 are detachably connected to the extraction tank 3, so that the cleaning and maintenance of the extraction tank 3 are convenient.

[0053] Working principle of the present invention: When the fermentation liquid separation and extraction device of the present invention is used, an appropriate amount of extractant is added to the extraction tank 3 through the liquid adding port 14. After the fermentation liquid is filtered by the plate and frame filter 1, the solid-liquid separation of the fermentation liquid is achieved. The filter cake after the filtration is initially crushed by the screw conveyor 2 and conveyed to the extraction tank 3. The material in the extraction tank 3 is further crushed by the crushing component 6. The third bevel gear 608 is driven to rotate by the motor 605, and then the first bevel gear 606 and the second bevel gear 607 are driven to rotate in the opposite direction, and the shaft cylinder 602 and the rotating shaft 601 are driven to rotate in the opposite direction. The rolling roller 603 at the bottom end of the shaft cylinder 602 rotates relative to the top surface of the sieve plate 604 to crush and crush the material. The annular groove 612 and the sieve hole 613 on the sieve plate 604 help to crush and fall the material. The arrangement of the scraper 610 and the rake teeth 611 further enhances the crushing effect, scrapes and stirs the material, and ensures that the material is fully crushed.

[0054] The crushed material falls into the extractant of the extraction tank 3 and mixes with the extractant. The anti-settling plate 8 can separate and block the material layer by layer to prevent the material from directly settling to the bottom of the extraction tank 3. The rotation of the rotating shaft 601 can drive the threaded rod 7 to rotate, and then drive the first stirring paddle 903 and the second stirring paddle 904 to rotate with the threaded rod 7. The first stirring paddle 903 stirs the material settled on the top surface of the anti-settling plate 8 to disperse it in the extractant and mix it with the extractant. The second stirring paddle 904 can stir and mix the dispersant and material above the anti-settling plate 8. By controlling the forward and reverse rotation of the motor 605, the rotating shaft 601 and the threaded rod 7 can be driven to rotate forward and reverse, thereby driving the anti-sinking plate 8 to move back and forth along the threaded rod 7, and then driving the first stirring paddle 903 and the second stirring paddle 904 to move up and down, so that the extractant at different positions in the extraction tank 3 can be stirred. At the same time, through the action of the anti-sinking plate 8, the flow of the extractant in the extraction tank 3 is further enhanced, so that the material can be more evenly dispersed in the extractant, thereby improving the extraction efficiency.

The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
