Description

Technical Field

[0001] This invention belongs to the field of defoaming technology, and particularly relates to a physical defoaming machine and defoaming method for a seawater distribution tank. Background Technology

[0002] The main breeding enterprises for giant freshwater prawns in my country are located in Huzhou and Jiaxing cities in Zhejiang Province, Gaoyou and Jiangdu districts in Jiangsu Province, Guangdong Province, and Guangxi Zhuang Autonomous Region, primarily in the inland areas of Jiangsu and Zhejiang, where there is no seawater supply. Due to the inherent characteristics of the breeding process, it is greatly affected by feed and water quality, resulting in unstable hatching. Furthermore, giant freshwater prawn breeding requires artificially prepared seawater, with a salinity maintained at around 12‰. However, during the preparation of seawater in the mixing tank, due to the dissolution of various seawater additives and the presence of organic matter in the source water, a large amount of foam will occur even with aeration measures.

[0003] To prevent impurities within the foam from dissolving into the seawater, workers currently remove the foam from a 3-meter-high distribution pool. Because seawater preparation takes a long time—multiple pools need to be prepared daily during peak periods—this requires multiple workers, is time-consuming, inefficient, and results in incomplete foam removal. It also poses safety risks to workers and is extremely inconvenient to operate. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1-4 This invention provides a physical defoaming machine for a seawater distribution tank, comprising:

[0032] Baffle 1, with a flow guide 11 at the bottom of baffle 1. The bottom of the flow guide 11 is open and in contact with the foam. A vacuum suction component and a bubble separation component are provided on baffle 1. The vacuum suction component and the bubble separation component are correspondingly provided with the flow guide 11. The vacuum suction component is used to generate suction to suck up the foam, and the bubble separation component is used to return the liquid in the sucked foam back to the pool. An outlet pipe 6 is connected to the vacuum suction component and is used to export the sucked foam.

[0033] The sensing component is installed on the baffle 1. The sensing component includes a sensing device and a foam detection alarm device. The sensing device is used to periodically identify the amount of foam in the pool and control the operation of the vacuum suction component and the bubble separation component. The foam detection alarm device is used to issue an alarm when the foam disappears, control the vacuum suction component and the bubble separation component to stop operating, and remind the staff.

[0034] The fixing component includes a fixing element and a position adjustment unit. The position adjustment unit is disposed on the fixing component, and the baffle 1 is disposed on the position adjustment unit.

[0035] The main function of the flow guide shroud 11 is to guide the flow of foam; the main function of the vacuum suction component is to generate upward suction to draw in the foam and then discharge the foam along the outlet pipe 6; the main function of the bubble separation component is to use centrifugal force to throw the liquid in the drawn foam back into the distribution pool; the main function of the sensing device is to identify the foam situation on the surface of the distribution pool and control the vacuum suction component and the bubble separation component to operate at different power levels according to the amount of foam; the main function of the foam detection alarm device is to control the vacuum suction component and the bubble separation component to stop operating after the foam disappears and issue an alarm signal to remind the staff to handle the foam; the main function of the fixing component is to stably place the defoaming device of the present invention on the side of the distribution pool; the main function of the position adjustment unit is to increase the defoaming area by adjusting the spatial position of the baffle 1 on the water surface of the distribution pool. Overall, the present invention can automatically and efficiently extract foam from the distribution pool, with a wide range of foam extraction, and can effectively prevent impurities in the foam from remaining in the distribution pool and contaminating the seawater being distributed.

[0036] Further optimization of the scheme: the vacuum suction component includes a vacuum cover 2 fixedly connected to the top of the baffle 1. A water pump 5 is fixedly connected to the top of the vacuum cover 2. The inlet of the water pump 5 is connected to the inside of the vacuum cover 2. The outlet of the water pump 5 is connected to one end of the outlet pipe 6. A number of first through holes 9 are opened on the baffle 1. The vacuum cover 2 is connected to the inside of the guide cover 11 through the number of first through holes 9.

[0037] Further optimization of the design: Pump 5 can be a vertical centrifugal pump, model 20SG2-8, with a power of 0.12KW, a diameter of 20mm, and a pumping capacity of 2m³ / h.3 / h, with a head of 8m, which can meet the usage requirements.

[0038] like Figure 1 As shown, when the water pump 5 operates, it generates negative pressure inside the vacuum chamber 2. Due to the reduced air pressure inside the vacuum chamber 2, outside air flows in through several first through holes 9. Since the guide shroud 11 is positioned above the water surface and within the foam during operation, after the water pump 5 generates negative pressure, the guide shroud 11, in conjunction with the water pump 5, can draw the foam from the bottom of the guide shroud 11 into the vacuum chamber 2. Finally, the water pump 5 pumps the foam into the outlet pipe 6, and through the outlet pipe 6, it flows into a pre-prepared barrel-shaped container for subsequent foam processing.

[0039] Further optimization of the scheme: the bubble separation component includes a first motor 4 fixedly connected to the top of the vacuum shroud 2. The output shaft of the first motor 4 is coaxially fixedly connected to one end of a rotating shaft 7. The other end of the rotating shaft 7 is provided with a turbine component, which is located inside the flow guide shroud 11. The turbine component is used to achieve water and bubble separation.

[0040] The turbine component is further optimized by including a front cover 12 and a rear cover 13 arranged coaxially. The end of the rotating shaft 7 away from the first motor 4 is fixedly connected coaxially to one side of the front cover 12. The front cover 12 and the rear cover 13 are fixedly connected by several guide plates 15. Several second through holes 14 are provided on the front cover 12, and the several second through holes 14 are correspondingly arranged with several first through holes 9. A through hole 16 is provided on the rear cover 13, and the through hole 16 is correspondingly arranged with the opening at the bottom of the guide cover 11.

[0041] In a further optimized design, the bottom of the flow guide 11 and the baffle 1 are fixedly connected by several connecting rods 10, and a gap is provided between the flow guide 11 and the baffle 1.

[0042] like Figures 1-3 As shown, a liquid guide channel 33 is formed between two adjacent guide plates 15. When the foam is sucked upwards, the first motor 4 rotates synchronously, driving the worm gear through the rotating shaft 7. After the foam is sucked into the guide shroud 11 by negative pressure, it enters the area between the front cover 12 and the rear cover 13 through the through hole 16. The foam rotates synchronously in the area between the front cover 12 and the rear cover 13. Due to centrifugal force, the heavier liquid is thrown towards the direction of the guide plates 15 and eventually ejected from several liquid guide channels 33. The ejected liquid flows back into the distribution tank through the gap between the guide shroud 11 and the baffle 1. The remaining foam, under the negative pressure generated by the water pump 5, enters the vacuum shroud 2 sequentially through the second through hole 14 and the first through hole 9.

[0043] Further optimization of the scheme: the sensing device includes several sensors 8 fixedly connected to the baffle 1, which are used to detect and identify the amount of foam in the pool.

[0044] like Figure 1 and Figure 2 As shown, sensor 8 can be a model MLU02-205 sensor. Utilizing convolutional neural network (CNN) technology, 10,000 images are initially acquired, and a CNN model based on the amount of foam in the water is constructed within sensor 8. During operation, image recognition technology monitors the foam condition on the surface of the water distribution tank in real time to obtain real-time images of its operating status. Based on the acquired images, the trained CNN model identifies the amount of foam every 2 minutes and outputs a signal (0: very high; 1: moderate; 2: low) to pump 5. Specifically, if a very high amount of foam is detected after an image detection, sensor 8 controls pump 5 to operate at higher power and simultaneously controls the first motor 4 to rotate, in order to quickly eliminate the foam; if a low amount of foam is detected after an image detection, pump 5 is controlled to operate at lower power, and the first motor 4 is controlled to rotate; similarly, if no foam is detected, pump 5 and the first motor 4 do not operate.

[0045] Further optimization of the scheme: the foam detection alarm device includes several detection alarms 32 fixedly connected to the baffle 1. The several detection alarms 32 are used to detect the remaining amount of foam in the pool and to sound an alarm after the foam disappears.

[0046] like Figure 1 and Figure 2 As shown, the detection alarm 32 can be a model SS-168. After the sensor 8 controls the water pump 5 and the first motor 4 to operate, the detection alarm 32 will detect the foam on the water surface through a real-time image device. Once the disappearance of foam is detected, the water pump 5 and the first motor 4 will stop operating, and an alarm signal will be issued to remind the staff to deal with the foam in the barrel-shaped container in time. The sensor 8 and the detection alarm 32 work together to achieve closed-loop control, making the defoaming process rapid and efficient.

[0047] In a further optimized design, a protective shell 3 is fixedly connected to the top of the vacuum chamber 2, and the water pump 5 and the first motor 4 are installed inside the protective shell 3. The protective shell 3 is installed on the position adjustment unit.

[0048] The scheme is further optimized. The position adjustment unit includes a rotating shaft 26 that is vertically rotatably mounted on a fixed component and a third motor 28 that is fixedly connected to the fixed component. The top end of the rotating shaft 26 is provided with a displacement part. A gear ring 27 is fixedly sleeved on the rotating shaft 26. A gear 29 is fixedly sleeved on the output shaft of the third motor 28. The gear 29 meshes with the gear ring 27.

[0049] In a further optimized design, the displacement unit includes a rotating seat 24 fixedly connected to the top of the rotating shaft 26. A guide rod 21 is horizontally fixedly connected to the side wall of the rotating seat 24. A groove 22 is provided at the bottom of the guide rod 21. A slider 20 is slidably connected in the groove 22. A lead screw 25 is rotatably connected in the groove 22. The lead screw 25 is drivenly connected to the slider 20. A second motor 23 is drivenly connected to one end of the lead screw 25. The second motor 23 is fixedly connected in the rotating seat 24. A sliding plate 19 is fixedly connected to the bottom of the slider 20. The sliding plate 19 is fixedly connected to the baffle 1 through a height adjustment unit.

[0050] The design is further optimized so that the height adjustment unit includes an electric telescopic rod 18 and several guide telescopic rods 17. The electric telescopic rod 18 and several guide telescopic rods 17 are arranged in parallel and the two ends of the electric telescopic rod 18 and several guide telescopic rods 17 are respectively fixedly connected to the protective shell 3 and the sliding plate 19.

[0051] like Figure 4 As shown, several sensors 8 are electrically connected to the third motor 28. When identifying the amount of foam on the water surface, the system also identifies areas with more foam based on the image. By controlling the rotation of the third motor 28, the motor drives the rotating shaft 26 to rotate via gear 29 and gear ring 27. When the rotating shaft 26 rotates, it causes the guide shield 11 to swing horizontally left and right via the rotating seat 24, guide rod 21, sliding plate 19, and guide telescopic rod 17. By controlling the rotation of the second motor 23, the second motor drives the lead screw 25 to rotate. When the lead screw 25 rotates, it causes the slider 20 to slide within the groove 22, and the distance between the guide shield 11 and the rotating shaft 26 is adjusted via the sliding plate 19 and guide telescopic rod 17. By controlling the length of the electric telescopic rod 18, the height of the guide shield 11 above the water surface is controlled to achieve the best foam absorption effect. Simultaneously, the length of the rotating shaft 26 can be adjusted to match the telescopic arm of the selected electric telescopic rod 18 to ensure smooth contact between the guide shield 11 and the foam.

[0052] The design is further optimized so that the fasteners include a base 30 and a counterweight 31 fixedly connected to the top of the base 30. The rotating shaft 26 and the counterweight 31 are located on both sides of the base 30, respectively.

[0053] A defoaming method for a seawater distribution tank includes the following steps:

[0054] A network model based on the amount of foam in water was constructed using sensing devices;

[0055] In the early stage, 10,000 images of the water distribution pool were collected, and a convolutional neural network model based on the amount of foam in the water was constructed in sensor 8.

[0056] The fixing component is fixedly placed on the side of the water distribution pool, so that the flow guide shroud 11 is located above the water distribution pool;

[0057] Place the base 30 next to the water distribution pool, and use the counterweight 31 to ensure that the guide shroud 11 is stably above the water surface. At the same time, connect the outlet pipe 6 to the barrel-shaped container.

[0058] The foam condition on the surface of the water distribution tank is monitored in real time by the sensing device. When defoaming treatment is required, the position adjustment unit is controlled to move the guide hood 11 to a suitable position, and then the vacuum suction component and the bubble separation component are controlled to operate to carry out defoaming treatment.

[0059] Turn on sensor 8 and detection alarm 32. Sensor 8 identifies the amount of foam in the water distribution tank every two minutes, and automatically controls water pump 5 to suck up the foam at different working power based on the amount of foam generated. At the same time, it controls the first motor 4 to run, and throws the liquid in the sucked foam back into the water distribution tank.

[0060] During the defoaming process, the amount of foam is detected by a foam detection alarm device. Once the foam disappears, the vacuum suction component and the bubble separation component are stopped, and an alarm is issued to remind the staff to take the next step.

[0061] While the water pump 5 and the first motor 4 are working, the detection alarm 32 detects the amount of foam on the water surface through images. Once the foam disappears, the detection alarm 32 immediately controls the water pump 5 and the first motor 4 to work and issues an alarm to remind aquaculture workers to deal with the foam at the suction point in a timely manner.
