Description

Technical Field

[0001] This invention relates to the field of fermentation product separation equipment technology, specifically to a rapid separation and filtration device for Astragalus compound probiotic fermentation products. Background Technology

[0002] Astragalus compound probiotic fermentation product is obtained by synergistic fermentation of astragalus extract with probiotics (such as lactic acid bacteria and bifidobacteria). It combines the medicinal active ingredients of astragalus with the physiological functions of probiotics and has broad application prospects in the fields of food, health products, and medicine. In the industrial production process of fermentation product, separation and filtration are key steps. The purpose is to remove impurities such as culture medium residues, bacterial aggregates, and polysaccharide viscous substances from the fermentation broth, while maximizing the preservation of probiotic activity and astragalus activity.

[0003] Existing fermentation product separation and filtration devices generally suffer from the following problems: First, filtration and residue collection are performed in separate steps, making real-time residue collection impossible. This leads to residue accumulation on the surface of the filter components, forming a filter cake, which severely affects filtration efficiency and hinders rapid, real-time residue collection, impacting the device's usability. Second, the high moisture content of the residue during collection makes subsequent processing difficult. Third, the filter components are mostly fixed structures, resulting in insufficient contact between the fluid and the filter medium and a slow filtration rate. To address these issues, this invention proposes a rapid separation and filtration device for Astragalus compound probiotic fermentation products that integrates real-time residue collection, precise staged filtration, residue dehydration, and high-efficiency filtration. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rapid separation and filtration device for Astragalus compound probiotic fermentation products. By installing a separation and collection module along the axial direction of the separation and filtration tank, the residues generated by the primary and secondary separation and filtration modules can be discharged to the outside of the device in real time through the separation and collection module. During the discharge process, water can be squeezed out, reducing the difficulty of subsequent operations. Furthermore, this device has good filtration effect and high efficiency, solving the problems of current devices being unable to achieve real-time cleaning of filter residues and having poor separation and filtration effects.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: A rapid separation and filtration device for Astragalus compound probiotic fermentation products includes a separation and filtration tank and a cover plate fixedly connected to the top of the separation and filtration tank by bolts. A separation and collection module for collecting filter residue is fixedly connected between the bottom inner side of the separation and filtration tank and the cover plate. The separation and collection module includes a collection pipe, which consists of an arc-shaped section, a residue discharge section integrally formed at the upper end of the arc-shaped section, and a residue feed section integrally formed at the lower end of the arc-shaped section. A support is fixedly connected to the top of the residue discharge section, and a round rod is rotatably connected between the support and the bottom inner side of the collection pipe. A screw conveyor blade for collecting residue is fixedly connected to the outer wall of the round rod. Furthermore, a motor for controlling the rotation of the circular rod is installed at the center of the lower surface of the separation and filtration tank; the separation and filtration device also includes a primary separation and filtration module and a secondary separation and filtration module that are rotatably connected to the residue feeding section along the flow direction of the fermentation products. The residue feeding section has an array of primary feed ports distributed around the bottom of the primary separation and filtration module along the circumference of the collection pipe, and the residue feeding section has an array of secondary feed ports distributed around the bottom of the secondary separation and filtration module along the circumference of the collection pipe. The primary separation and filtration module and the secondary separation and filtration module discharge the filter residue into the collection pipe through the primary feed port and the secondary feed port, respectively, to achieve automatic collection of the filter residue.

[0006] Furthermore, the residue discharge section is fixedly connected to the center of the cover plate, and the protruding edge at the bottom of the residue feed section is fixedly connected to the inner bottom of the separation filter tank by bolts.

[0007] Furthermore, the primary separation and filtration module includes an annular seat rotatably connected to the outer wall of the residue feeding section, a conical ring welded to the top of the annular seat , and a support frame fixedly connected radially to the upper end of the conical ring in an annular pattern. The upper end of the support frame is fixedly connected to a circular ring . A conical filter screen is fixedly connected to the support frame . A bottom filter screen is fixedly connected to each of the hollow cavities opened in the array of the conical ring .

[0008] Furthermore, the secondary separation and filtration module includes an annular seat two rotatably connected to the outer wall of the residue feeding section, a conical ring two welded to the top of the annular seat two, and a support frame two fixedly connected in a radial pattern to the upper end of the conical ring two. The upper end of the support frame two is fixedly connected to a circular ring two. A conical filter screen two is fixedly connected to the support frame two, and a bottom filter screen two is fixedly connected to each of the hollow cavities opened in the array of conical ring two. A sedimentation tank is formed between the conical ring one and the residue feeding section, and between the conical ring two and the residue feeding section, so that the filtered residue enters the residue feeding section through the corresponding filter port.

[0009] Furthermore, an external toothed ring is fixedly connected to the outer wall of the first ring, and an internal toothed ring is fixedly connected to the inner wall of the second ring. A second motor is installed on the cover plate. The rotating shaft connected to the output shaft of the second motor extends into the interior of the separation and filtration tank and is fixedly connected to a gear. The gear meshes with the external toothed ring and the internal toothed ring respectively, realizing the reverse rotation operation of the primary separation and filtration module and the secondary separation and filtration module, thereby accelerating the separation and filtration of fermentation products.

[0010] Furthermore, a blocking control module for adjusting the slag discharge status of the primary and secondary feed inlets is fixedly connected to the separation filter tank. The blocking control module includes a mounting plate, an electric push rod, and an annular body. An annular groove is opened on the inner wall of the residue feeding section corresponding to the primary and secondary feed inlets, and the annular body is slidably connected to the groove. The mounting plate is fixedly connected to the lower surface of the separation filter tank, the electric push rod is mounted on the mounting plate, and a circular plate is coaxially fixedly connected to the end of the output shaft of the electric push rod. An array of support rods is fixedly connected to the upper surface of the circular plate. The support rods extend through holes corresponding to those in the separation filter tank and the collection pipe into the collection pipe and are fixedly connected to the annular body. The annular body can slide up and down at the groove to realize the blocking control operation of the primary or secondary feed inlet.

[0011] Furthermore, the upper surface of the cover plate is provided with a collection cylinder for collecting filter residue. The collection cylinder includes a cylinder body, and an outer ring and an inner ring integrally formed on the cylinder body. The inner ring is detachably sleeved on the residue discharge section, and an inclined groove is opened at the top of the inner ring near the residue discharge section to store the filter residue discharged by the separation and collection module.

[0012] Furthermore, a feeding module is installed on the cover plate. The feeding module includes an annular pipe and nozzles that are connected sequentially at equal intervals to the bottom of the annular pipe. The nozzles are evenly distributed circumferentially above the primary separation and filtration module. The annular pipe is fixedly connected to the lower surface of the cover plate by a fixing seat, and the feeding pipe connected to the annular pipe extends to the top of the cover plate through corresponding holes.

[0013] Furthermore, an inner scraping mechanism for cleaning the filter cake on filter screen one is fixedly connected to the outer wall of the collection pipe, and an outer scraping mechanism for cleaning the filter cake on filter screen two is fixedly connected to the support frame one. The inner scraping mechanism includes a support rod one fixedly connected to the arc-shaped section, and a flexible scraper one welded to the end of the support rod one. The flexible scraper one makes slight contact with filter screen one to achieve the cleaning operation of the filter cake on filter screen one. The outer scraping mechanism includes a support rod two fixedly connected to the support frame one, and a flexible scraper two welded to the end of the support rod two. The flexible scraper two makes slight contact with filter screen two to achieve the cleaning operation of the filter cake on filter screen two. A flow turbulence mechanism is also fixedly connected to the support frame one. The flow turbulence mechanism includes a mounting base fixedly connected to the support frame one, and a flow turbulence plate welded to the mounting base. The flow turbulence mechanism can increase fluid turbulence and improve filtration efficiency.

[0014] Furthermore, the bottom of the separation filter tank is connected to a discharge pipe, and a valve is installed on the discharge pipe. A support leg is fixedly connected to the separation filter tank.

[0015] Compared with the prior art, the present invention provides a rapid separation and filtration device for Astragalus compound probiotic fermentation products, which has the following beneficial effects: 1. This invention, through the coordinated operation of the separation and collection module and the primary and secondary separation and filtration modules, combined with the guiding effect of the sedimentation tank, allows the residue generated by filtration to be deposited in a timely manner and enter the collection pipe through the inlet. Real-time collection is then achieved through the rotation and conveying of the auger blades, preventing residue accumulation from affecting filtration efficiency. Simultaneously, the precise control of the blocking control module ensures that the secondary inlet is blocked when collecting residue from the primary separation and filtration module, and vice versa, effectively preventing fluid cross-flow and thus guaranteeing the graded filtration effect. This method enables real-time collection of filtered residue. Furthermore, the arc-shaped section of the collection pipe adopts a circular arc design. When the residue is conveyed by the auger blades within the arc section, the inner wall of the arc exerts a squeezing effect on the residue, thereby removing the attached moisture, reducing the difficulty of subsequent residue processing, and improving separation efficiency. After the moisture is removed, the residue enters the collection cylinder through the residue discharge section. The collection cylinder can be directly removed for convenient practical use.

[0016] 2. In this invention, the second motor drives the primary separation and filtration module and the secondary separation and filtration module to rotate in opposite directions through the meshing of gears with the external and internal gear rings, increasing the relative speed of the fermentation products and the filter screen. At the same time, the turbulence mechanism increases the degree of fluid turbulence, and the internal and external scraping mechanisms clean the filter cake in real time. The multiple functions work together to improve the filtration rate, achieve rapid separation, and ensure the separation and filtration effect of the Astragalus compound probiotic fermentation products.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] like Figures 1-12As shown in the figure, an embodiment of the present invention provides a rapid separation and filtration device for Astragalus compound probiotic fermentation products, including a separation and filtration tank 1 and a cover plate 2 fixedly connected to the top of the separation and filtration tank 1 by bolts. A separation and collection module 4 for collecting filter residue is fixedly connected between the bottom inner side of the separation and filtration tank 1 and the cover plate 2. The separation and collection module 4 includes a collection pipe, which is composed of an arc-shaped section 401, a residue discharge section 402 integrally formed at the upper end of the arc-shaped section 401, and a residue feed section 4011 integrally formed at the lower end of the arc-shaped section 401. A support 403 is fixedly connected to the top of the residue discharge section 402. A round rod 404 is rotatably connected between the support 403 and the bottom inner side of the collection pipe. An auger for collecting residue is fixedly connected to the outer wall of the round rod 404. The blade 405 and a motor 4010 for controlling the rotation of the round rod 404 are installed at the center of the lower surface of the separation filter tank 1; the separation filter device also includes a primary separation filter module 6 and a secondary separation filter module 7 that are rotatably connected to the residue feeding section 4011 along the flow direction of the fermentation product. The residue feeding section 4011 has an array of primary feed ports 406 arranged around the bottom of the primary separation filter module 6 and an array of secondary feed ports 407 arranged around the bottom of the secondary separation filter module 7. The primary separation filter module 6 and the secondary separation filter module 7 discharge the filter residue into the collection pipe through the primary feed port 406 and the secondary feed port 407 respectively, so as to realize the automatic collection of the filter residue.

[0021] It should be noted that the separation filter tank 1 and the cover plate 2 constitute a closed filtration space, forming the main body of the device and providing a sealed environment for subsequent separation and filtration. The separation collection module 4 serves as the core for collecting filter residue. Its collection pipe forms a complete residue conveying channel through the arc section 401, the residue discharge section 402, and the residue feed section 4011. After the motor 4010 starts, it drives the round rod 404 to rotate, which in turn drives the auger blades 405 to rotate synchronously, generating a continuous spiral conveying force. The primary separation filter module 6 and the secondary separation filter module 7 are distributed sequentially along the flow direction of the fermentation products to achieve the filtration of graded fermentation products. The residue produced by filtration enters the collection pipe through the corresponding primary feed port 406 and secondary feed port 407, respectively. Under the spiral thrust of the auger blades 405, it moves along the collection pipe, ultimately completing the automatic collection of residue and forming a continuous process of filtration-feeding-conveyance. This method can achieve real-time collection of filter residue, and the moisture in the residue can be removed during the collection process, which is convenient for subsequent processing. Real-time cleaning of residue also ensures the filtration effect of fermentation products.

[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, in some embodiments, the residue discharge section 402 is fixedly connected to the center of the cover plate 2, and the protruding flange 409 of the residue feed section 4011 is fixedly connected to the inner bottom of the separation filter tank 1 by bolts.

[0023] It should be noted that the residue discharge section 402 is fixed to the center of the cover plate 2 to ensure that the axis of the collection pipe coincides with the axis of the separation filter tank 1, providing a positioning guarantee for the subsequent discharge of residue along the central channel; the residue feed section 4011 is fixed to the bottom of the inner side of the separation filter tank 1 by bolts through the protrusion 409, so as to achieve a stable installation of the lower end of the collection pipe and prevent it from shifting or shaking during the rotation of the auger blade 405 and the conveying of residue.

[0024] like Figure 9 As shown, in some embodiments, the primary separation and filtration module 6 includes an annular seat 601 rotatably connected to the outer wall of the residue feeding section 4011, a conical ring 607 welded to the top of the annular seat 601, and a support frame 602 fixedly connected in annular radial pattern to the upper end of the conical ring 607. A circular ring 604 is fixedly connected to the upper end of the support frame 602. A conical filter screen 603 is fixedly connected to the support frame 602, and a bottom filter screen 606 is fixedly connected to each of the hollow cavities opened in the array of conical rings 607.

[0025] It should be noted that the annular seat 601 provides rotational support for the primary separation and filtration module 6, enabling it to rotate around the outer wall of the residue feed section 4011; the annular radial support frame 602 connects the conical ring 607 and the circular ring 604, forming a stable support frame, and also provides an installation carrier for the filter screen 603; the conical filter screen 603 increases the contact area with the fermentation products. When the fermentation products flow through, large particulate impurities (such as culture medium residue and bacterial aggregates) are intercepted by the filter screen 603, achieving primary filtration; the bottom filter screen 606 on the conical ring 607 covers the hollow cavity, forming a complete filter surface, preventing impurities from leaking through the hollow cavity, ensuring the comprehensiveness of primary filtration, and also preventing the accumulation of fermentation liquid. The intercepted impurities are deposited at the bottom of the conical ring 607 under the action of gravity, preparing for subsequent entry into the primary feed inlet 406.

[0026] like Figure 6 , Figure 9 and Figure 10As shown, in some embodiments, the secondary separation and filtration module 7 includes an annular seat 701 rotatably connected to the outer wall of the residue feeding section 4011, a conical ring 707 welded to the top of the annular seat 701, and a support frame 702 fixedly connected in an annular radial pattern to the upper end of the conical ring 707. A circular ring 704 is fixedly connected to the upper end of the support frame 702. A conical filter screen 703 is fixedly connected to the support frame 702, and a bottom filter screen 706 is fixedly connected to each of the hollow cavities opened in the array of conical rings 707. A sedimentation tank is formed between the conical ring 707 and the residue feeding section 4011, and between the conical ring 707 and the residue feeding section 4011, so that the filtered residue enters the residue feeding section 4011 through the corresponding filter port.

[0027] It should be noted that the annular seat 701 provides rotational support for the secondary separation and filtration module 7, allowing it to rotate around the outer wall of the residue feed section 4011; the support frame 702 connects the conical ring 707 and the circular ring 704, forming a stable frame and providing an installation base for the filter screen 703; the fermentation products after primary filtration flow to the secondary separation and filtration module 7, where the conical filter screen 703 (with a higher filtration precision than the filter screen 603) further traps small particulate impurities (such as polysaccharide viscous substances and fine bacterial aggregates). This achieves two-stage fine filtration; the bottom filter screen 706 covers the hollow cavity of the conical ring 707, ensuring that there are no dead corners on the filtration surface and facilitating liquid outflow. The conical ring 607 and the conical ring 707 form sedimentation tanks with the residue feed section 4011, respectively. The impurities intercepted by the primary and secondary filtration are deposited into the corresponding sedimentation tanks under the action of gravity and fluid flow. The annular structure of the sedimentation tank guides the impurities to converge towards the primary feed inlet 406 and the secondary feed inlet 407, facilitating the smooth entry of impurities into the residue feed section 4011 and improving the residue collection efficiency.

[0028] like Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, in some embodiments, an outer toothed ring 605 is fixedly connected to the outer wall of the first ring 604, and an inner toothed ring 705 is fixedly connected to the inner wall of the second ring 704. A second motor 13 is installed on the cover plate 2. The rotating shaft 14 connected to the output shaft of the second motor 13 extends into the interior of the separation filter tank 1 and is fixedly connected to a gear 15. The gear 15 meshes with the outer toothed ring 605 and the inner toothed ring 705 respectively, realizing the reverse rotation operation of the primary separation filter module 6 and the secondary separation filter module 7, thereby accelerating the separation and filtration of fermentation products.

[0029] It should be noted that after motor 13 starts, its output shaft drives the rotating shaft 14 and gear 15 to rotate. Gear 15 simultaneously meshes with the outer gear ring 605 (outer wall of ring 604) and the inner gear ring 705 (inner wall of ring 704). Utilizing the directional characteristics of gear 15, the outer gear ring 605 and the inner gear ring 705 rotate in opposite directions, thereby driving the primary separation filter module 6 and the secondary separation filter module 7 to rotate in opposite directions (e.g., primary clockwise, secondary counterclockwise). The reverse rotation of the modules causes relative movement between the fermentation products and filter screens 603 and 703, which on the one hand reduces the adhesion of impurities on the filter screens and reduces the filter cake formation rate, and on the other hand increases the degree of fluid turbulence and accelerates the rate at which the fermentation products pass through the filter screens, thereby accelerating the separation and filtration process.

[0030] like Figure 2 , Figure 6 and Figure 7 As shown, in some embodiments, a blocking control module 9 for adjusting the slag discharge state of the primary feed inlet 406 and the secondary feed inlet 407 is fixedly connected to the separation filter tank 1. The blocking control module 9 includes a mounting plate 901, an electric push rod 902, and an annular body 905. An annular groove 408 is provided on the inner wall of the residue feeding section 4011 corresponding to the primary feed inlet 406 and the secondary feed inlet 407, and the annular body 905 is slidably connected to the groove 408. The mounting plate 901 is fixedly connected to the separation filter tank 1. On the lower surface, an electric push rod 902 is mounted on a mounting plate 901, and a circular plate 903 is coaxially fixedly connected to the end of the output shaft of the electric push rod 902. An array of support rods 904 are fixedly connected to the upper surface of the circular plate 903. The support rods 904 extend into the collection pipe through holes corresponding to those opened in the separation filter tank 1 and the collection pipe, and are fixedly connected to the annular body 905. The annular body 905 can slide up and down at the slide groove 408 to realize the blocking control operation of the primary feed port 406 or the secondary feed port 407.

[0031] It should be noted that the mounting plate 901 provides fixed support for the electric push rod 902. The electric push rod 902 acts as a power source, and the extension and retraction of its output shaft drives the circular plate 903 to move synchronously up and down. The circular plate 903 transmits power through the arrayed support rods 904, driving the annular body 905 to slide axially within the groove 408. When the annular body 905 moves downward, its sidewall blocks the secondary feed inlet 407, while the primary feed inlet 406 remains open. At this time, the residue from the primary separation and filtration module 6 can enter the collection pipe, and the secondary residue is temporarily stored in the sedimentation tank. When the annular body 905 moves upward, its sidewall blocks the primary feed inlet 406, while the secondary feed inlet 407 opens, allowing the residue from the secondary separation and filtration module 7 to enter the collection pipe. The alternating blocking and opening of the primary and secondary feed inlets 407 through the up-and-down sliding of the annular body 905 prevents fluid cross-flow and ensures the orderly operation of staged filtration and residue collection.

[0032] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, in some embodiments, the upper surface of the cover plate 2 is provided with a collection cylinder 3 for collecting filter residue. The collection cylinder 3 includes a cylinder body 301, and an outer ring 302 and an inner ring 303 integrally formed on the cylinder body 301. The inner ring 303 is detachably sleeved on the residue discharge section 402, and an inclined groove 304 is opened at the top of the inner ring 303 near the residue discharge section 402, so as to store the filter residue discharged by the separation collection module 4.

[0033] It should be noted that the collecting cylinder 3 is detachably fitted onto the residue discharge section 402 via the inner ring 303, enabling quick docking and disassembly with the separation and collecting module 4. After the residue is discharged through the residue discharge section 402 of the separation and collecting module 4, the inclined groove 304 at the top of the inner ring 303 acts as a guide, allowing the residue to flow smoothly into the cylinder 301 for storage. The outer ring 302 increases the structural stability of the collecting cylinder 3 and facilitates the operator's handling and disassembly.

[0034] like Figure 4 and Figure 5 As shown, in some embodiments, a feeding module 5 is installed on the cover plate 2. The feeding module 5 includes an annular pipe 501 and nozzles 503 that are connected sequentially at equal intervals to the bottom of the annular pipe 501. The nozzles 503 are evenly distributed circumferentially above the primary separation and filtration module 6. The annular pipe 501 is fixedly connected to the lower surface of the cover plate 2 by a fixing seat 502, and the feeding pipe 504 connected to the annular pipe 501 extends to the top of the cover plate 2 through the corresponding holes opened in the cover plate 2.

[0035] It should be noted that the feed pipe 504 is connected to the fermentation product of Astragalus compound probiotics, and the product is transported into the annular pipe 501. The annular pipe 501 is fixed to the lower surface of the cover plate 2 by the fixing seat 502. Its annular structure, together with the equally distributed nozzles 503, makes the fermentation product evenly distributed to each nozzle 503. The nozzles 503 are located directly above the primary separation and filtration module 6, and spray the fermentation product evenly on the upper surface of the filter screen 603, so as to avoid the local accumulation of fermentation product, which would cause the filter screen to be blocked or the filtration unevenly. This ensures that the filtration surface of the primary separation and filtration module 6 is fully utilized, and improves the filtration efficiency and the uniformity of the filtration effect. The feed pipe 504 can be connected to an external feed pump to realize the orderly feeding of fermentation product.

[0036] like Figure 4 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, in some embodiments, an inner scraping mechanism 10 for cleaning the filter cake on filter screen 603 is fixedly connected to the outer wall of the collection pipe, and an outer scraping mechanism 11 for cleaning the filter cake on filter screen 703 is fixedly connected to the support frame 602. The inner scraping mechanism 10 includes a support rod 1001 fixedly connected to the arc-shaped section 401, and a flexible scraper 1002 welded to the end of the support rod 1001. The flexible scraper 1002 makes slight contact with the filter screen 603 to achieve the cleaning operation of the filter cake on the filter screen 603. The outer scraping mechanism 11... The system includes a second support rod 1101 fixedly connected to the support frame 602, and a second flexible scraper 1102 welded to the end of the second support rod 1101. The second flexible scraper 1102 makes slight contact with the second filter screen 703 to clean the filter cake on the second filter screen 703. The support frame 602 is also fixedly connected to a flow turbulence mechanism 12, which includes a mounting base 1201 fixedly connected to the support frame 602, and a flow turbulence plate 1202 welded to the mounting base 1201. The flow turbulence mechanism 12 can increase fluid turbulence and improve filtration efficiency.

[0037] It should be noted that the internal scraping mechanism 10: the support rod 1001 is fixed to the arc-shaped section 401 of the collection pipe, so that the flexible scraper 1002 is kept in a fixed position. When the primary separation filter module 6 rotates, the filter screen 603 and the flexible scraper 1002 move relative to each other. The flexible scraper 1002 scrapes the filter cake formed on the surface of the filter screen 603 in a slight contact manner, so as to avoid the filter cake clogging the filter screen pores and ensure the smoothness of primary filtration.

[0038] External scraping mechanism 11: Support rod 2 1101 is fixed to support frame 1 602 and rotates synchronously with primary separation filter module 6. Flexible scraper 2 1102 and rotating filter screen 2 703 generate relative movement, slightly contacting and scraping the filter cake on the surface of filter screen 2 703 to prevent secondary filter screen from clogging and maintain secondary filtration efficiency.

[0039] Flow disturbance mechanism 12: Mounting base 1201 fixes the flow disturbance plate 1202 to the support frame 602. As the primary separation and filtration module 6 rotates, the flow disturbance plate 1202 disturbs the fluid in the separation and filtration tank 1, breaks the laminar flow state, increases the degree of fluid turbulence, accelerates the contact frequency and penetration speed between fermentation products and the filter screen, and at the same time reduces the adhesion of impurities on the surface of the filter screen. It works in conjunction with the scraping mechanism to improve the overall filtration efficiency.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the bottom of the separation filter tank 1 is connected to a discharge pipe 8, and a valve is installed on the discharge pipe 8, and a support leg is fixedly connected to the separation filter tank 1.

[0041] It should be noted that the clarified fermentation product (finished product) after primary and secondary separation and filtration collects at the bottom of separation and filtration tank 1 under the action of gravity. The discharge pipe 8 serves as the finished product output channel, and its valve is used to control the start and stop of the discharge and the flow rate. Operators can adjust the valve status according to the filtration progress and collection needs to achieve orderly collection of the finished product.

[0042] The working principle and usage steps of this invention are as follows: First, the fermentation product is fed through the feed pipe 504 and evenly sprayed onto the primary separation and filtration module 6 via the nozzle 503 through the annular pipe 501. Then, motor 1 4010 and motor 2 13 are started, and the electric push rod 902 drives the annular body 905 to move down and block the secondary feed inlet 407. The primary separation and filtration module 6 and the secondary separation and filtration module 7 rotate synchronously in opposite directions to achieve the filtration operation of the fermentation product in stages. After the residue settles, it enters the collection pipe through the primary feed inlet 406, is squeezed and dehydrated by the screw conveyor blades 405, and is transported to the collection cylinder 3. After a certain period of time, the electric push rod 902 drives the annular body 905 to move up and block the primary feed inlet 406. The secondary separation and filtration module 7 rotates in opposite directions for fine filtration. The residue enters the collection pipe through the secondary feed inlet 407, is dehydrated, and discharged into the collection cylinder 3. This cycle is repeated to achieve real-time collection of residue. After the filtration operation is completed, the valve of the discharge pipe 8 is opened to collect and clarify the fermentation product.

[0043] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
