Description

Technical Field

[0001] This utility model relates to the technical field of separation devices, and in particular to a one-step enzymatic separation device for preparing anti-flocculation chitosan oligosaccharides. Background Technology

[0002] Antiflocculating chitosan oligosaccharide is a chitosan oligosaccharide product with specific functions, mainly used to prevent the aggregation and sedimentation of suspended particles and maintain the stability and transparency of the solution. The production process of chitosan oligosaccharide requires membrane separation, where the supernatant is passed through an ultrafiltration membrane with a molecular weight cutoff to remove large-molecule chitosan and enzyme proteins, etc., and then the concentrated supernatant is placed in a low-temperature drying oven for low-temperature drying. Chinese utility model patent CN218421404U discloses a separation device for chitosan oligosaccharides. This device includes a separation tank, a collection tank, a control panel, and a feed inlet. The control panel is fixedly connected to the left side of the separation tank. The collection tank is located at the bottom of the inner wall of the separation tank. The feed inlet is located at the top left side of the separation tank and is connected to it. A filter plate is installed inside the separation tank, and the control panel is fixedly connected to the top left side of the separation tank. By incorporating a cleaning mechanism, the filter plate can be cleaned, preventing excessive accumulation of impurities on its surface and subsequent clogging. Simultaneously, the collection mechanism collects the cleaned impurities for processing. This solves the problem that during the separation of supernatant and impurities, high-concentration impurities easily adhere to the end face of the separation membrane, causing membrane clogging and resulting in slow downward flow of the supernatant, thus affecting the separation efficiency.

[0003] However, the impurity collection mechanism of the above-mentioned separation equipment uses a sealing block to open the connecting groove to allow impurities to enter the collection box. The sealing block slides up and down, which makes the seal between the sealing block and the connecting groove easy to wear, thus making it difficult to guarantee the sealing performance. The supernatant containing anti-flocculation chitosan oligosaccharide will also seep into the collection box, resulting in a reduction in separation efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a one-step enzymatic preparation device for separating anti-flocculating chitosan oligosaccharides, which can automatically and efficiently discharge high-concentration impurity liquids, has good sealing performance, and improves the separation efficiency of anti-flocculating chitosan oligosaccharides.

[0005] This invention relates to a one-step enzymatic preparation device for separating anti-flocculating chitosan oligosaccharides. The device includes a separation tank, a cover plate, and an inlet pipe. The separation tank has an internal separation chamber. A cover plate is installed on the top of the separation tank, and the inlet pipe is mounted on the cover plate, with its output end extending into the top of the separation chamber. The device also includes a coarse separation membrane, a fine separation membrane, a first siphon, a first impurity container, a second siphon, and a second impurity container. The coarse separation membrane is installed in the upper part of the separation chamber, and the fine separation membrane is installed in the middle of the separation chamber. Both the coarse and fine separation membranes are conical. The bottom of the separation chamber is a storage area. The input end of the first siphon extends into the upper part of the separation chamber and is located at the top of the coarse separation membrane. Above the membrane, the input end of siphon one is near the low edge of the coarse separation membrane, and the middle of siphon one is the high point one. The output end of siphon one extends into impurity tank one, and the output end of siphon one is lower than the coarse separation membrane. The input end of siphon two extends into the upper part of the separation chamber of the separation tank and is located above the fine separation membrane. The input end of siphon two is near the low edge of the fine separation membrane, and the middle of siphon two is the high point two. The output end of siphon two extends into impurity tank two, and the output end of siphon two is lower than the fine separation membrane. During operation, a clear liquid containing anti-flocculation chitosan oligosaccharide is introduced into the upper part of the separation chamber of the separation tank through the inlet pipe. The clear liquid falls onto the coarse separation membrane, ensuring that the coarse separation membrane... The liquid level of the clear liquid on the membrane is lower than the highest point of the siphon tube, causing the clear liquid to undergo primary filtration through the coarse separation membrane. The coarse separation membrane intercepts large particulate impurities. The clear liquid filtered through the coarse separation membrane falls onto the fine separation membrane, undergoing secondary filtration through the fine separation membrane. The fine separation membrane intercepts small particulate impurities. The clear liquid filtered through the fine separation membrane falls into the storage area. As the separation process continues, the amount of impurities on the coarse and fine separation membranes increases, causing the liquid level to rise. When the liquid level of the clear liquid containing a large number of large particulate impurities on the coarse separation membrane reaches the highest point of the siphon tube, the lower point of the coarse separation membrane is aligned with the output end of the siphon tube. The system connects the coarse separation membrane containing large particulate impurities to the impurity tank under siphon action. Similarly, when the liquid level of the fine separation membrane containing a large number of small particulate impurities reaches the high point of the siphon tube, the low point of the fine separation membrane is connected to the output end of the siphon tube. Under siphon action, the fine separation membrane containing small particulate impurities is discharged to the impurity tank, achieving automatic and efficient overall discharge of high-concentration impurity liquids without the need for sealing or moving parts. This ensures airtightness, prevents premature discharge of the supernatant containing anti-flocculation chitosan oligosaccharides, and improves the separation efficiency of anti-flocculation chitosan oligosaccharides.

[0006] Preferably, the system also includes contact switch one and contact switch two. Contact switch one is installed on siphon tube one, and its probe extends into the siphon tube one. Contact switch two is installed on siphon tube two, and its probe extends into the siphon tube two. When liquid is discharged through siphon tube one, the liquid passes through the probe of contact switch one, causing contact switch one to generate an electrical signal. Based on this signal, the liquid is rapidly delivered to the upper part of the separation chamber of the separator through the inlet pipe, so that the liquid on the coarse separation membrane quickly reaches the set liquid level, ensuring the separation and filtration efficiency of the coarse separation membrane, and simultaneously counting the amount of large particulate impurities discharged. When liquid is discharged through contact switch two, the liquid passes through the probe of contact switch two, causing contact switch two to generate an electrical signal, and the amount of small particulate impurities discharged is counted based on the above signal.

[0007] Preferably, it also includes a gas supply pipe and a pressure sensor. Both the gas supply pipe and the pressure sensor are mounted on the cover plate. The gas supply pipe and its output end extend into the top of the separation chamber of the separator, and the probe of the pressure sensor extends into the separation chamber of the separator. Gas is supplied to the upper part of the separation chamber of the separator through the gas supply pipe, so that the gas pressure above the coarse separation membrane is higher, thereby increasing the speed of the clarified liquid being filtered and separated through the coarse separation membrane. The pressure sensor detects the gas pressure on the coarse separation membrane to keep the gas pressure stable.

[0008] Preferably, it also includes a siphon tube three, which is installed in the storage area of ​​the separation chamber of the separator. The input end of the siphon tube three is close to the bottom wall of the separator, the middle part of the siphon tube three is the high point three, which is located below the fine separation membrane, and the output end of the siphon tube three extends out of the bottom of the separator. When the liquid level of the clear liquid three in the storage area of ​​the separation chamber of the separator reaches the high point three, the siphon tube three connects the storage area of ​​the separation chamber of the separator with the bottom of the separator, so that the clear liquid three in the storage area is discharged as a whole through the siphon tube three, realizing quantitative automatic discharge without the need for special quantitative mechanisms and sensors, etc., which is practical.

[0009] Preferably, the device also includes a motor, a shaft tube, and multiple scrapers. The motor is mounted on the cover plate via a bracket, and the motor's output shaft is connected to the upper end of the shaft tube. The lower part of the shaft tube extends into the separation chamber of the separator. Multiple scrapers are mounted on the shaft tube, and the scrapers scrape the upper surfaces of the coarse and fine separation membranes respectively. The motor drives the shaft tube to rotate, and the shaft tube drives the multiple scrapers to rotate, so that the multiple scrapers scrape the upper surfaces of the coarse and fine separation membranes respectively, thereby preventing the coarse and fine separation membranes from being clogged by impurities and improving the filtration stability of the coarse and fine separation membranes.

[0010] Preferably, the assembly also includes multiple nozzles and a rotary joint. The shaft tube is hollow inside, and the multiple nozzles are mounted on the shaft tube and communicate with the inside of the shaft tube. The multiple nozzles are located below the coarse separation membrane and the fine separation membrane, respectively. Each of the multiple nozzles is provided with multiple air blowing holes, which face the coarse separation membrane and the fine separation membrane, respectively. The rotary joint is mounted on the cover plate through the nozzle. The inner ring of the rotary joint is fitted onto the shaft tube and communicates with the inside of the shaft tube. The outer ring of the rotary joint is fitted with a connector. The connector of the rotary joint is connected to a backflushing water pipe or an air pipe. Backflushing water or air is input into the hollow interior of the shaft tube through the rotary joint and sprayed upwards from the bottom of the coarse separation membrane and the fine separation membrane through the multiple air blowing holes on the multiple nozzles, so that the coarse separation membrane and the fine separation membrane maintain their filtration effect. By setting the rotary joint, the shaft tube can stably deliver backflushing water or air even when rotating.

[0011] Compared with the prior art, the beneficial effects of this utility model are: no sealing parts and movable parts are required, thereby ensuring the sealing performance, preventing the supernatant containing anti-flocculation chitosan oligosaccharide from being discharged in advance, and improving the separation efficiency of anti-flocculation chitosan oligosaccharide.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0019] like Figures 1 to 4 As shown, a one-step enzymatic preparation device for anti-flocculating chitosan oligosaccharide separation includes a separation tank 1, a cover plate 2, and an inlet pipe 3. The separation tank 1 has an internal separation chamber. The cover plate 2 is installed on the top of the separation tank 1, and the inlet pipe 3 is installed on the cover plate 2, with its output end extending into the top of the separation chamber of the separation tank 1. The device also includes a coarse separation membrane 4, a fine separation membrane 5, a first siphon tube 6, a first impurity container 7, a second siphon tube 8, and a second impurity container 9. The coarse separation membrane 4 is installed in the upper part of the separation chamber of the separation tank 1, and the fine separation membrane 5 is installed in the middle of the separation chamber of the separation tank 1. The coarse separation membrane 4 and the fine separation membrane 5 are conical. The bottom of the separation chamber of the separation tank 1 is a storage area. The input end of siphon tube 6 extends into the upper part of the separation chamber of the separation tank 1 and is located above the coarse separation membrane 4. The input end of siphon tube 6 is near the low edge of the coarse separation membrane 4. The middle part of siphon tube 6 is the high point. The output end of siphon tube 6 extends into the impurity tank 7 and is lower than the coarse separation membrane 4. The input end of siphon tube 8 extends into the upper part of the separation chamber of the separation tank 1 and is located above the fine separation membrane 5. The input end of siphon tube 8 is located near the low edge of the fine separation membrane 5, and the middle of siphon tube 8 is the high point. The output end of siphon tube 8 extends into the impurity container 9, and the output end of siphon tube 8 is lower than the fine separation membrane 5. It also includes contact switch 10 and contact switch 11. Contact switch 10 is mounted on siphon tube 6, and its probe extends into the interior of siphon tube 6. Contact switch 11 is mounted on siphon tube 8, and its probe extends into the interior of siphon tube 8. It also includes a gas supply pipe 12 and a pressure sensor 1. 3. Both the gas filling pipe 12 and the pressure sensor 13 are mounted on the cover plate 2. The gas filling pipe 12 and its output end extend into the top of the separation chamber of the separator 1, and the probe of the pressure sensor 13 extends into the separation chamber of the separator 1. It also includes a siphon tube 3 14, which is installed in the storage area of ​​the separation chamber of the separator 1. The input end of the siphon tube 3 14 is close to the bottom wall of the separator 1 at a low position. The middle part of the siphon tube 3 14 is the high point 3, which is located below the fine separation membrane 5. The output end of the siphon tube 3 14 extends out of the bottom of the separator 1.

[0020] During operation, a clear liquid containing anti-flocculation chitosan oligosaccharide is introduced into the upper part of the separation chamber of the separator 1 through the inlet pipe 3. The clear liquid falls onto the coarse separation membrane 4, ensuring that the liquid level on the coarse separation membrane 4 is lower than the highest point of the siphon pipe 6. Gas is supplied to the upper part of the separation chamber of the separator 1 through the gas supply pipe 12, increasing the gas pressure above the coarse separation membrane 4 and thus increasing the speed at which the clear liquid passes through the coarse separation membrane 4 for filtration and separation. The pressure sensor 13 detects the gas pressure on the coarse separation membrane 4 and keeps the gas pressure stable, allowing the clear liquid to pass through the coarse separation membrane 4 for further processing. In the first-stage filtration separation, the coarse separation membrane 4 intercepts large particulate impurities. The clear liquid filtered through the coarse separation membrane 4 falls onto the fine separation membrane 5, allowing for secondary filtration separation. The fine separation membrane 5 intercepts small particulate impurities, and the clear liquid filtered through the fine separation membrane 5 falls into the storage area. As the separation process continues, the amount of impurities on the coarse separation membrane 4 and the fine separation membrane 5 increases, causing the liquid level to rise. When the liquid level of the clear liquid containing a large number of large particulate impurities on the coarse separation membrane 4 reaches the highest point of the siphon tube 6, The lower part of the coarse separation membrane 4 is connected to the output end of siphon tube 6. Under the siphon effect, the clear liquid containing large particulate impurities on the coarse separation membrane 4 is completely discharged into the impurity tank 7 through siphon tube 6. Similarly, when the liquid level of the clear liquid containing a large number of small particulate impurities on the fine separation membrane 5 reaches the higher point of siphon tube 8, the lower part of the fine separation membrane 5 is connected to the output end of siphon tube 8. Under the siphon effect, the clear liquid containing small particulate impurities on the fine separation membrane 5 is completely discharged into the impurity tank 9 through siphon tube 8, thus achieving the separation of high concentrations of impurities. The automatic and efficient overall discharge of impurity liquid is achieved when the liquid level of the clear liquid in the storage area of ​​the separation chamber of the separator 1 reaches the high point 3. The siphon pipe 3 14 connects the storage area of ​​the separation chamber of the separator 1 with the bottom of the separator 1, so that the clear liquid in the storage area is discharged as a whole through the siphon pipe 3 14. This achieves quantitative automatic discharge without the need for special quantitative mechanisms and sensors, as well as sealing components and moving parts, thus ensuring sealing and preventing the supernatant containing anti-flocculation chitosan oligosaccharide from being discharged prematurely, thereby improving the separation efficiency of anti-flocculation chitosan oligosaccharide.

[0021] When liquid is discharged through siphon tube 6, the liquid passes through the probe of contact switch 10, causing contact switch 10 to generate an electrical signal. Based on this signal, the liquid is rapidly transported through inlet pipe 3 to the upper part of the separation chamber of separation tank 1, so that the liquid on coarse separation membrane 4 quickly reaches the set liquid level, ensuring the separation and filtration efficiency of coarse separation membrane 4, and at the same time counting the amount of large particulate impurities discharged. When liquid is discharged through contact switch 21, the liquid passes through the probe of contact switch 21, causing contact switch 21 to generate an electrical signal, and the amount of small particulate impurities discharged is counted based on the above signal. Example 2

[0022] like Figure 4 and Figure 5As shown, based on Embodiment 1, it also includes a motor 15, a shaft tube 16, and multiple scrapers 17. The motor 15 is mounted on the cover plate 2 via a bracket. The output shaft of the motor 15 is connected to the upper end of the shaft tube 16. The lower part of the shaft tube 16 extends into the separation chamber of the separation tank 1. Multiple scrapers 17 are mounted on the shaft tube 16 and scrape the upper surfaces of the coarse separation membrane 4 and the fine separation membrane 5 respectively. It also includes multiple nozzles 18 and a rotary joint 19. The shaft tube 16 is hollow inside. Multiple nozzles 18 are mounted on the shaft tube 16 and communicate with the inside of the shaft tube 16. The multiple nozzles 18 are located below the coarse separation membrane 4 and the fine separation membrane 5 respectively. Multiple air blowing holes are provided on each of the multiple nozzles 18 and face the coarse separation membrane 4 and the fine separation membrane 5 respectively. The rotary joint 19 is mounted on the cover plate 2 through the gap. The inner ring of the rotary joint 19 is fitted onto the shaft tube 16 and communicates with the inside of the shaft tube 16. The outer ring of the rotary joint 19 is fitted with a connector.

[0023] Motor 15 drives shaft tube 16 to rotate, shaft tube 16 drives multiple scrapers 17 to rotate, so that multiple scrapers 17 scrape the upper surfaces of coarse separation membrane 4 and fine separation membrane 5 respectively, thereby preventing coarse separation membrane 4 and fine separation membrane 5 from being blocked by impurities and improving the filtration stability of coarse separation membrane 4 and fine separation membrane 5; the joint of rotary joint 19 is connected to backflushing water pipe or air pipe, backflushing water or air is input into the hollow interior of shaft tube 16 through rotary joint 19 and sprayed upward from the bottom of coarse separation membrane 4 and fine separation membrane 5 through multiple air blowing holes on multiple nozzles 18, so that coarse separation membrane 4 and fine separation membrane 5 maintain filtration effect. By setting rotary joint 19, the shaft tube 16 can stably deliver backflushing water or air when rotating.

[0024] like Figures 1 to 5As shown, the one-step enzymatic preparation device for anti-flocculating chitosan oligosaccharide separation of this invention, during operation, firstly, a clear liquid containing anti-flocculating chitosan oligosaccharide is introduced into the upper part of the separation chamber of the separation tank 1 through the inlet pipe 3. The clear liquid falls onto the coarse separation membrane 4, ensuring that the liquid level on the coarse separation membrane 4 is lower than the high point of the siphon tube 6, so that the clear liquid undergoes primary filtration separation through the coarse separation membrane 4. The coarse separation membrane 4 intercepts large particulate impurities. Then, the clear liquid filtered through the coarse separation membrane 4 falls onto the fine separation membrane 5, so that the clear liquid undergoes further filtration through the fine separation membrane 5. Secondary filtration separation: the fine separation membrane 5 intercepts small particulate impurities, and the clear liquid filtered through the fine separation membrane 5 falls into the storage area. As the separation process continues, more and more impurities accumulate on the coarse separation membrane 4 and the fine separation membrane 5, causing the liquid level to rise. During this process, the motor 15 drives the shaft tube 16 to rotate, which in turn drives multiple scrapers 17 to rotate. These scrapers 17 scrape the upper surfaces of the coarse separation membrane 4 and the fine separation membrane 5 respectively. Backflush water or air is introduced into the hollow interior of the shaft tube 16 through the rotary joint 19 and passes through multiple nozzles. Multiple air vents on membrane 18 spray water or air upwards from the bottom of the coarse separation membrane 4 and the fine separation membrane 5 to maintain their filtration effect. When the liquid level of the clear liquid containing a large number of large particulate impurities on the coarse separation membrane 4 reaches the high point of the siphon tube 6, the low point of the coarse separation membrane 4 is connected to the output end of the siphon tube 6. Under the siphon effect, the clear liquid containing large particulate impurities on the coarse separation membrane 4 is completely discharged into the impurity tank 7 through the siphon tube 6. Similarly, when the clear liquid containing a large number of small particulate impurities on the fine separation membrane 5 reaches the high point of the siphon tube 6, the liquid level of the coarse separation membrane 4 reaches the high point of the siphon tube 6. When the liquid level reaches the high point of the siphon tube 28, the low point of the fine separation membrane 5 is connected to the output end of the siphon tube 28. Under the siphon action, the clear liquid containing small particulate impurities on the fine separation membrane 5 is discharged into the impurity tank 29 through the siphon tube 28. Finally, when the liquid level of the clear liquid 3 in the storage area of ​​the separation chamber of the separation tank 1 reaches the high point 3, the siphon tube 314 connects the storage area of ​​the separation chamber of the separation tank 1 with the bottom of the separation tank 1, so that the clear liquid 3 in the storage area is discharged as a whole through the siphon tube 314, thus realizing quantitative automatic discharge.
