Description

Technical Field

[0001] The present invention relates to the technical field of preparation equipment, and more specifically, to an abalone polysaccharide extraction device and a usage method thereof. Background Art

[0002] Abalone polysaccharide is a bioactive substance extracted from abalone and has various biological activities and health benefits. The extraction method of abalone polysaccharide mainly includes the following steps: removing the shell and taking the meat (including internal organs) of abalone, using a tissue homogenizer to break the cell wall, adding water and mixing evenly, then extracting at 20 - 80°C for 2 - 6 hours, centrifuging for separation, adding water to the insoluble matter again and repeating the extraction 1 - 2 times, and combining the supernatant. Subsequently, the extract is concentrated to a sugar content of 1.5% - 3.0%, adding 3 - 4 times the volume of 95% ethanol, and performing alcohol precipitation at 0 - 4°C for 12 - 16 hours. After centrifugation, the product is obtained through a spray drying device.

[0003] However, during the process of spray drying abalone polysaccharide to make a product, because abalone polysaccharide has a large molecular weight, it is extremely easy to form a complex network structure in the solution. This special structure results in extremely poor fluidity in the solution. Taking the concentration as an example, when the concentration of abalone polysaccharide solution exceeds 5%, its viscosity will rise above 1000 mPa·s, while the viscosity of water is only 1 mPa·s. Such a high viscosity makes the abalone polysaccharide solution extremely likely to stay in the nozzle channels of the spray drying device. Over time, it will cause nozzle blockage.

[0004] In addition, abalone polysaccharide will undergo a series of complex physical and chemical changes in a high-temperature environment. When in the high-temperature environment of spray drying, the polysaccharide molecules will quickly dehydrate and undergo a cross-linking reaction to form a highly viscous gel film. This gel film will adhere to the nozzle outlet, resulting in material residue. Over time, the residues accumulate continuously, and eventually, it will also cause nozzle blockage.

[0005] The problem of nozzle blockage has a serious impact on the normal operation of the spray drying device. Once the nozzle is blocked, the spray drying process cannot proceed smoothly, resulting in a significant reduction in production efficiency. At the same time, due to factors such as the prolonged residence time of the material in the device and uneven heating, the drying efficiency and drying effect of abalone polysaccharide will also be greatly reduced. The dried product may have problems such as caking and uneven water content, seriously affecting the quality and market value of the product. Summary of the Invention

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an abalone polysaccharide extraction device and a using method, which can realize the real-time detection and automatic cleaning of blocked nozzles, ensuring the continuity and stability of the abalone polysaccharide spray drying process. This not only improves production efficiency but also guarantees the uniformity and consistency of the quality of the dried abalone polysaccharide product, avoiding problems such as material residue and uneven drying caused by nozzle blockage.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] An abalone polysaccharide extraction device includes a drying tank. An installation seat is installed at the upper end of the drying tank. A liquid delivery pipe is arranged above the installation seat. The lower end of the liquid delivery pipe is connected with two groups of diversion pipes. The lower ends of the diversion pipes penetrate through the installation seat and extend into the interior of the drying tank. The outer side wall of the diversion pipe is slidably arranged with the installation seat. The lower end of the diversion pipe is installed with a nozzle pipe. Multiple groups of nozzles are arranged on the side wall of the nozzle pipe. An activity cavity is arranged at the side wall of each group of diversion pipes inside the installation seat.

[0009] A cleaning component is arranged inside the activity cavity. The cleaning component is used to clean the blocked nozzles. The cleaning component includes an ultrasonic vibration rod, and the ultrasonic vibration rod acts on the cleaning liquid in the activity cavity to clean the nozzles.

[0010] A detection component is installed on the liquid delivery pipe. The detection component is used to detect whether the nozzles on one group of nozzle pipes are blocked. The detection component includes a liquid pressure sensor and a flow rate sensor. The liquid pressure sensor is used to detect the liquid pressure inside the liquid delivery pipe, and the flow rate sensor is used to detect the liquid flow rate inside the liquid delivery pipe.

[0011] A telescopic component is arranged above the activity cavity inside the installation seat. The telescopic component is used to control the blocked nozzle to enter the activity cavity. The telescopic component includes a moving disk. The moving disk is fixedly installed on the side wall of the diversion pipe. The up and down movement of the moving disk drives the diversion pipe and drives the nozzle to enter the activity cavity.

[0012] Furthermore, the detection component also includes:

[0013] Previously, the abalone polysaccharide solution is pumped into the liquid delivery pipe by a water pump and sprayed out from the nozzles of one group of nozzle pipes. By adjusting the power of the water pump, the corresponding flow rates of the liquid in the liquid delivery pipe under different pressure conditions are recorded.

[0014] When drying the abalone polysaccharide solution, if the measured liquid flow rate in the liquid delivery pipe under the corresponding pressure is less than the previously recorded flow rate, it is determined that the nozzles of the current working nozzle pipe are blocked.

[0015] If the measured liquid flow rate in the infusion tube at the corresponding pressure is greater than the previously recorded flow rate, it is determined that the nozzle of the current working nozzle tube is structurally damaged.

[0016] Further, the detection component further includes:

[0017] At the corresponding pressure, subtract the currently measured flow rate from the previously recorded flow rate to obtain a flow rate difference, and multiply the flow rate difference by the cleaning coefficient to obtain the cleaning duration of the blocked nozzle.

[0018] Further, the detection component further includes:

[0019] When the nozzle on the nozzle tube works again after cleaning, compare the measured flow rate with the previously recorded flow rate at the corresponding pressure. If the measured flow rate is lower than the recorded flow rate, use the difference between the recorded flow rate and the measured flow rate as the feedback value, and update the cleaning coefficient through the feedback value. The updated cleaning coefficient will be used to calculate the next cleaning duration.

[0020] Further, the detection component further includes:

[0021] Record in real time the time nodes of nozzle blockage on the nozzle tube and the working duration between adjacent blockage events to form a time series training sample. Input the training sample into the learning model training module, establish a blockage time prediction model through iterative learning, and predict the time node of nozzle blockage on the nozzle tube at the next moment based on the current working condition data and the trained blockage time prediction model.

[0022] Further, the telescopic component further includes a limiting cylinder. The limiting cylinder is sleeved outside the guide pipe, and the limiting cylinder is located below the moving disk. A space for the up and down movement of the moving disk is provided inside the mounting seat. A spring is sleeved outside the guide pipe, and the spring is arranged above the moving disk. An air pipe is arranged inside the mounting seat, and the lower end opening of the air pipe is arranged below the moving disk. The upper end of the air pipe penetrates through the mounting seat and is connected to an external air pump;

[0023] A telescopic hole for the nozzle tube to enter and exit is provided on the bottom wall of the movable cavity. A sealing pad is fixedly connected to the lower end of the nozzle tube, and the sealing pad is used to seal the telescopic hole. A rubber pad is bonded to the upper end surface of the sealing pad. A corrugated pipe and a first solenoid valve are also connected between the infusion tube and the guide pipe. The corrugated pipe is connected to the upper end of the guide pipe, the upper end of the corrugated pipe is connected to the first solenoid valve, and the end of the first solenoid valve away from the corrugated pipe is connected to the infusion tube.

[0024] Further, the cleaning assembly further includes an annular plate which is sleeved on the diversion pipe, and the lower end of the annular plate is rotatably connected to the inner wall of the lower end of the movable cavity. Soft hairs are bonded to the inner wall of the annular plate. A gear is meshed and connected to the outer side surface of the annular plate, and a motor is installed at the upper end of the gear. The motor is installed inside the mounting seat.

[0025] Further, the cleaning assembly further includes a liquid injection pipe. The lower end of the liquid injection pipe is arranged inside the movable cavity. The upper end of the liquid injection pipe penetrates through the mounting seat and extends to the outside. A second electromagnetic valve is installed at the upper end of the liquid injection pipe. A storage tank is installed at one end of the second electromagnetic valve away from the liquid injection pipe. Cleaning liquid is installed inside the storage tank.

[0026] Further, a drain pipe is arranged inside the mounting seat. One end of the drain pipe extends into the movable cavity. The end of the drain pipe away from the movable cavity penetrates through the mounting seat and extends to the outside. A third electromagnetic valve is installed on the drain pipe.

[0027] The present invention also provides a usage method applicable to the above-mentioned abalone polysaccharide extraction device, including the following steps:

[0028] Step 1: Start the device. Pump the abalone polysaccharide solution into the infusion pipe through a water pump. Open one group of first electromagnetic valves, so that the abalone polysaccharide solution enters the diversion pipe through the corrugated pipe and finally sprays out from the nozzle of the nozzle pipe and enters the drying tank for drying.

[0029] Step 2: The liquid pressure sensor detects the liquid pressure in the infusion pipe in real time, and the flow rate sensor detects the liquid flow rate in the infusion pipe in real time. According to the liquid pressure data detected by the liquid pressure sensor, retrieve the flow rate data in the infusion pipe under the corresponding pressure before. Compare the current flow rate data with the retrieved flow rate data. If the current flow rate is less than the retrieved flow rate, it is determined that there is a blockage at the nozzle of the currently working nozzle pipe; if the current flow rate is greater than the retrieved flow rate, it is determined that the nozzle of the currently working nozzle pipe is damaged.

[0030] Step 3: When a blockage at the nozzle is detected, close the first electromagnetic valve corresponding to the blocked nozzle pipe to stop its operation. Open the first electromagnetic valve corresponding to another group of unblocked nozzle pipes to make it continue to work. The air pump inflates the air pipe corresponding to the blocked nozzle pipe to push the moving disk and the diversion pipe to move upward, so that the nozzle pipe and the nozzle enter the movable cavity for blockage removal.

[0031] Step 4: After the cleaning is completed, open the third electromagnetic valve to discharge the cleaning liquid in the movable cavity through the drain pipe.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] (1) By detecting in real time and automatically cleaning the blocked nozzles, this solution ensures the continuity and stability of the abalone polysaccharide spray drying process. This not only improves production efficiency but also guarantees the uniformity and consistency of the quality of the dried abalone polysaccharide product, avoiding material residue and uneven drying problems caused by nozzle blockage.

[0034] (2) By introducing a detection component and a learning model, this solution can record in real time the time nodes of nozzle blockage and the working duration between adjacent blockage events, forming time-series training samples. By training the learning model, it is possible to predict the time nodes of nozzle blockage at the next moment, so as to arrange the cleaning plan in advance and achieve predictive maintenance. This not only reduces manual intervention but also decreases the equipment failure rate and improves the overall operating efficiency of the equipment.

[0035] (2) After the nozzle on each set of nozzle pipes is blocked, this solution controls the corresponding cleaning work to be carried out in the corresponding activity cavity, and at the same time controls another set of nozzle pipes with unblocked nozzles to extend into the drying tank for spraying operation. This alternating working mode ensures the continuity and stability of the abalone polysaccharide production process, avoids production interruption caused by nozzle blockage, and greatly improves production efficiency and equipment utilization rate.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Please refer to Figures 1 to 6 , an abalone polysaccharide extraction device, including a drying tank 1, a mounting seat 2 is installed at the upper end of the drying tank 1, an infusion tube 3 is arranged above the mounting seat 2, two groups of diversion tubes 6 are connected to the lower end of the infusion tube 3, the lower ends of the diversion tubes 6 penetrate through the mounting seat 2 and extend into the interior of the drying tank 1, the outer side wall of the diversion tube 6 is slidably arranged with the mounting seat 2, a sprinkler tube 9 is installed at the lower end of the diversion tube 6, and a plurality of spray nozzles 10 are opened on the side wall of the sprinkler tube 9. Activity cavities 12 are opened at the inner part of the mounting seat 2 at the side wall of each diversion tube 6;

[0047] A detection component is installed on the infusion tube 3, and the detection component is used to detect whether the spray nozzle 10 on one of the sprinkler tubes 9 is blocked. The detection component includes a liquid pressure sensor 4 and a flow rate sensor 5. The liquid pressure sensor 4 is used to detect the liquid pressure inside the infusion tube 3, and the flow rate sensor 5 is used to detect the liquid flow rate in the infusion tube 3;

[0048] The detection component further includes:

[0049] Previously, the abalone polysaccharide solution is pumped into the infusion tube 3 by a water pump and sprayed out from the spray nozzle 10 of one of the sprinkler tubes 9. By adjusting the power of the water pump, the corresponding flow rates of the liquid in the infusion tube 3 under different pressure conditions are recorded;

[0050] When drying the abalone polysaccharide solution, if the measured liquid flow rate in the infusion tube 3 at the corresponding pressure is less than the previously recorded flow rate, it is determined that the spray nozzle 10 of the currently working sprinkler tube 9 is blocked;

[0051] If the measured liquid flow rate in the infusion tube 3 under the corresponding pressure is greater than the previously recorded flow rate, it is determined that the nozzle 10 of the currently working nozzle tube 9 has structural damage.

[0052] By adopting the above technical solution, when the abalone polysaccharide solution needs to be dried, the abalone polysaccharide solution is firstly transported to the infusion tube 3 by using a water pump, and then one of the first solenoid valves 7 (for convenience of description, the first solenoid valve 7 is opened) is opened. Figure 3 Taking the first solenoid valve 7 at the left end as an example, the abalone polysaccharide solution enters the corresponding bellows 8 through the opened first solenoid valve 7, and then enters the guide tube 6 from the bellows 8. The abalone polysaccharide solution moves along the guide tube 6, and finally flows into the nozzle tube 9 and is sprayed out from the nozzle 10, sprayed into the drying tank 1, and then the drying work is carried out. The mounting base 2 is also equipped with a control module. During operation, the liquid pressure sensor 4 detects the liquid pressure in the infusion tube 3 in real time. The control template retrieves the flow rate data in the infusion tube 3 under the previous corresponding pressure based on the liquid pressure data detected by the liquid pressure sensor 4, and then compares the retrieved flow rate data with the current flow rate data detected by the flow rate sensor 5 in the infusion tube 3. If the current flow rate data is less than the retrieved flow rate data, that is to say, under the same pressure in the infusion tube 3, the flow rate of the abalone polysaccharide solution has slowed down compared with before, indicating that the nozzle 10 is blocked. The retrieved flow rate data can be subtracted from the current flow rate data. When the difference reaches a preset difference or is higher than a preset difference, a cleaning operation is performed, and the nozzle 10 on the nozzle tube 9 needs to be cleared. At this time, the first solenoid valve 7 at the left end can be closed to stop the blocked nozzle 10 from working, and then the first solenoid valve 7 at the right end can be opened to make the nozzle 10 on a group of nozzle tubes 9 at the right end work.

[0053] If under the corresponding pressure, the current flow rate data detected is less than the retrieved flow rate data, the flow rate of the abalone polysaccharide solution has become faster than before, indicating that the nozzle 10 has been damaged. At this time, the control module can control the alarm system to perform an alarm operation to remind the staff to replace the nozzle tube 9. The alarm system can be alarmed by a buzzer installed on the outside of the drying tank 1. When the alarm is triggered, the control module controls the buzzer to make a sound to remind the staff; the alarm system can be alarmed by a flashing LED light installed on the outside of the drying tank 1. When the alarm is triggered, the control module controls the LED light to light up and flash to remind the staff.

[0054] like Figures 1 to 6 As shown, a telescopic assembly is arranged inside the mounting seat 2 above the active cavity 12, and the telescopic assembly is used to control the blocked nozzle 10 to enter the active cavity 12. The telescopic assembly includes a moving plate 25, and the moving plate 25 is fixedly mounted on the side wall of the guide tube 6. The guide tube 6 is driven by the up and down movement of the moving plate 25, and the nozzle 10 is driven to enter the active cavity 12;

[0055] The telescopic assembly further includes a limiting cylinder 24 sleeved outside the diversion pipe 6 and located below the moving disk 25. A space for the up-and-down movement of the moving disk 25 is provided inside the mounting seat 2. A spring 26 is sleeved outside the diversion pipe 6 and arranged above the moving disk 25. An air pipe 27 is provided inside the mounting seat 2. The lower end opening of the air pipe 27 is arranged below the moving disk 25. The upper end of the air pipe 27 penetrates through the mounting seat 2 and is connected to an external air pump.

[0056] An expansion hole 17 for the inlet and outlet of the spray head pipe 9 is provided on the inner bottom wall of the movable cavity 12. A sealing pad 11 is fixedly connected to the lower end of the spray head pipe 9 for sealing the expansion hole 17. A rubber pad 28 is bonded to the upper end surface of the sealing pad 11. A corrugated pipe 8 and a first electromagnetic valve 7 are further connected between the infusion pipe 3 and the diversion pipe 6. The corrugated pipe 8 is connected to the upper end of the diversion pipe 6. The upper end of the corrugated pipe 8 is connected to the first electromagnetic valve 7. One end of the first electromagnetic valve 7 away from the corrugated pipe 8 is connected to the infusion pipe 3.

[0057] By adopting the above technical solution, when it is detected that the spray nozzle 10 is blocked and reaches the cleaning threshold, the air pump inflates the corresponding air pipe 27, and the gas will flow into the lower part of the moving disk 25. The increased air pressure at the lower end of the moving disk 25 will push the moving disk 25 to move upward. While moving upward, the moving disk 25 will compress the spring 26. At the same time as the moving disk 25 moves upward, it will also drive the diversion pipe 6 to move upward synchronously. The upward movement of the diversion pipe 6 will drive the spray head pipe 9 to move upward, and the spray head pipe 9 will enter the expansion hole 17. Finally, the spray nozzle 10 on the spray head pipe 9 will enter the movable cavity 12 for cleaning operation. After the spray head pipe 9 enters the expansion hole 17, the sealing pad 11 presses against the lower end opening of the expansion hole 17 to seal the expansion hole 17.

[0058] When the blocked nozzle 10 enters the movable cavity 12 for cleaning, the air pump stops supplying air below the other set of moving disks 25 (that is, the set on the right end). It should be noted that the other set of moving disks 25 is previously supplied with air to retract the nozzle pipe 9 into the telescopic hole 17. After the air pump stops supplying air below the other set of moving disks 25, the previously compressed spring 26 elongates to drive the moving disk 25 to move downward. When the moving disk 25 moves downward, it drives the nozzle pipe 9 to extend out of the telescopic hole 17, and at the same time, the corresponding first solenoid valve 7 (that is, the set on the right end) is opened. The liquid in the infusion pipe 3 will be ejected from the nozzle 10 on the nozzle pipe 9 and dried. If the detection component detects that the nozzle 10 on this set of nozzle pipes 9 is blocked, it will also control the telescopic component to drive the nozzle 10 of the nozzle pipe 9 into the movable cavity 12 for blockage removal work. At the same time, the telescopic component drives the nozzle pipe 9 after the previous blockage removal to extend out of the corresponding telescopic hole 17 and perform spraying work. In the present invention, after the nozzle 10 on each set of nozzle pipes 9 is blocked, it is controlled to enter the corresponding movable cavity 12 for blockage removal work. At the same time, it is controlled that the nozzle pipes 9 of the other set with unblocked nozzles 10 extend into the drying tank 1 for spraying operation. This alternating working mode ensures the continuity and stability of the abalone polysaccharide production process, avoids production interruption caused by nozzle 10 blockage, and greatly improves production efficiency and equipment utilization rate.

[0059] As Figures 1 to 6 shown, a cleaning component is arranged inside the movable cavity 12. The cleaning component is used to clean the blocked nozzle 10. The cleaning component includes an ultrasonic vibrating rod 18, and the ultrasonic vibrating rod 18 acts on the cleaning liquid in the movable cavity 12 to clean the nozzle 10;

[0060] The cleaning component further includes an annular plate 13. The annular plate 13 is sleeved on the diversion pipe 6, and the lower end of the annular plate 13 is rotatably connected to the inner wall of the lower end of the movable cavity 12. Soft hairs 14 are bonded to the inner wall of the annular plate 13. A gear 15 is meshed and connected to the outer side surface of the annular plate 13. A motor 16 is installed at the upper end of the gear 15, and the motor 16 is installed inside the mounting seat 2;

[0061] The cleaning component further includes a liquid injection pipe 19. The lower end of the liquid injection pipe 19 is arranged inside the movable cavity 12. The upper end of the liquid injection pipe 19 penetrates through the mounting seat 2 and extends to the outside. A second solenoid valve 20 is installed at the upper end of the liquid injection pipe 19. A storage tank 21 is installed at one end of the second solenoid valve 20 away from the liquid injection pipe 19, and cleaning liquid is installed inside the storage tank 21;

[0062] A drain pipe 22 is arranged inside the mounting seat 2. One end of the drain pipe 22 extends into the movable cavity 12. The end of the drain pipe 22 away from the movable cavity 12 penetrates through the mounting seat 2 and extends to the outside. A third solenoid valve 23 is installed on the drain pipe 22.

[0063] By adopting the above technical solution, when the spray head pipe 9 retracts into the telescopic hole 17, the part of the spray head pipe 9 with the spray nozzle 10 at its upper end will enter into the annular plate 13. At this time, the corresponding second solenoid valve 20 is opened, and the cleaning liquid in the storage tank 21 will flow into the second movable cavity 12 along the liquid injection pipe 19. The cleaning liquid can be clean water heated to an appropriate temperature. After an appropriate amount of cleaning liquid is injected, the corresponding second solenoid valve 20 is closed. At this time, the ultrasonic vibration rod 18 is turned on. The ultrasonic vibration rod 18 acts on the cleaning liquid to clean the spray nozzle 10 with the cleaning liquid. Additionally, the motor 16 is turned on simultaneously. The motor 16 drives the gear 15 to rotate. During the rotation of the gear 15, the engaged annular plate 13 will be driven to rotate. During the rotation of the annular plate 13, the internal soft hair 14 will be driven to rotate. One end of the soft hair 14 away from the inner wall of the annular plate 13 contacts the outer wall of the spray head pipe 9. The soft hair 14 rotates to clean the substances around the spray nozzle 10 that are difficult to clean. Through the cleaning of the soft hair 14 and the ultrasonic vibration rod 18, the blockage removal work at the spray nozzle 10 can be completed. After reaching the blockage removal working duration, the corresponding third solenoid valve 23 is opened, and the cleaning liquid in the movable cavity 12 will be discharged through the drain pipe 22. After the cleaning liquid is drained, the corresponding third solenoid valve 23 is closed. The spray nozzle 10 after blockage removal is ready for use after the spray head pipe 9 extends out of the telescopic hole 17.

[0064] In some embodiments of the present invention, the detection component further includes:

[0065] At the corresponding pressure, subtract the currently measured flow rate from the previously recorded flow rate to obtain a flow rate difference , multiply the flow rate difference by a cleaning coefficient . The cleaning coefficient is an empirical coefficient that comprehensively considers various factors. It can be determined according to the material of the spray nozzle, the type of blockage, the cleaning method, and past cleaning experience to obtain the cleaning duration of the blocked spray nozzle 10 . By quantifying the degree of blockage, the situation of blind cleaning or insufficient cleaning can be avoided. This targeted cleaning strategy not only saves time and resources but also ensures the maximization of the cleaning effect.

[0066] In some embodiments of the present invention, the detection component further includes:

[0067] When the spray head pipe 9 works again after the spray nozzle 10 is cleaned, at the corresponding pressure, compare the measured flow rate with the previously recorded flow rate. If the measured flow rate is still lower than the recorded flow rate, it indicates that the spray nozzle 10 may still have a certain degree of blockage, or the cleaning work has not fully achieved the expected effect, then trigger the update mechanism of the cleaning coefficient;

[0068] If the measured flow rate is lower than the recorded flow rate , which is expressed as the flow rate measured when working again, then the difference between the recorded flow rate and the measured flow rate is used as the feedback value , and the cleaning coefficient is updated through the feedback value. The specific formula for the update coefficient is: . The updated cleaning coefficient will be used to calculate the next cleaning duration, where represents the ratio of the flow rate difference to the recorded flow rate and is used to measure the severity of the blockage; is a positive number used to adjust the sensitivity of the cleaning coefficient update. If is larger, the cleaning coefficient is more sensitive to changes in the flow rate difference, and the cleaning coefficient will also increase significantly, thus triggering a longer cleaning time; if is smaller, the update of the cleaning coefficient is smoother and less sensitive to changes in the flow rate difference. The value of can be adjusted by the staff according to the actual situation. For example, after cleaning the nozzle 10, if the current flow rate is continuously measured to be lower than the recorded flow rate for multiple times, the value of can be increased, thus triggering a longer cleaning time. In addition, to prevent the cleaning coefficient from being too large or too small, upper and lower limits of the cleaning coefficient can be set. If the result of the update calculation is within , the output result is ; if the result of the update calculation is , the output result is ; if the result of the update calculation is , the output result is . Through dynamically updating the cleaning coefficient, the present invention can more accurately reflect the current blockage condition and cleaning requirements of the nozzle 10, thereby formulating a more targeted and effective cleaning plan, which can not only improve the cleaning effect but also avoid unnecessary cleaning work, saving time and resources.

[0069] In some embodiments of the present invention, the detection component further includes:

[0070] Record the time nodes of the blockage of the nozzles 10 on the spray head pipe 9 in real time and the working duration between adjacent blockage events to form sequential training samples. Input the training samples into the learning model to train the module. The learning batch can be set. For example, set the learning batch to 500 times. After the number of blockages reaches 500 times, the learning model training is completed. Then, based on the current working condition data and the trained learning model, predict the time node of the blockage of the nozzles 10 on the spray head pipe 9 at the next moment. By predicting the time node of the blockage of the nozzles 10 on the corresponding spray head pipe 9, the cleaning plan can be arranged in advance to avoid production interruption and improve production efficiency. The learning model is a model for time series data, such as a long short-term memory network (LSTM).

[0071] The present invention also provides a usage method applicable to the above-mentioned abalone polysaccharide extraction equipment, including the following steps:

[0072] Step 1, start the equipment, pump the abalone polysaccharide solution into the infusion pipe 3 through a water pump, open one group of first solenoid valves 7, so that the abalone polysaccharide solution enters the diversion pipe 6 through the corrugated pipe 8, and finally sprays out from the nozzles 10 of the spray head pipe 9 and enters the drying tank 1 for drying;

[0073] Step 2, the liquid pressure sensor 4 detects the liquid pressure in the infusion pipe 3 in real time, and the flow rate sensor 5 detects the liquid flow rate in the infusion pipe 3 in real time. According to the liquid pressure data detected by the liquid pressure sensor 4, retrieve the flow rate data in the infusion pipe 3 under the corresponding pressure before. Compare the current flow rate data with the retrieved flow rate data.
