Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a treatment device and process for treating marine aquaculture wastewater. Background Technology

[0002] Marine aquaculture refers to aquaculture activities conducted in marine or saline environments, primarily involving the cultivation of aquatic organisms such as fish, shellfish, and algae. Compared to freshwater aquaculture, marine aquaculture typically offers a richer variety of species and higher economic value. In aquaculture, wastewater is the water discharged after changes in water quality due to factors such as the metabolism of farmed organisms, feed residues, drug use, and various biological activities in the water. This wastewater usually requires treatment before safe discharge or reuse, and pollutants in this water easily adhere to aquaculture nets, necessitating regular cleaning. This process helps reduce pollution of surrounding waters, protects the health of aquatic organisms, and ensures the sustainable development of the aquaculture industry.

[0003] For example, Chinese patent CN112871815A discloses a fishing net cleaning device for aquaculture, which includes a motor, a threaded screw, a water tank, a fixed base, a fixed steel frame, a water pump, a fixed clamp, a nozzle, a connecting frame, and a spraying device. The water tank is installed at the center of the top of the fixed base, and first slide rails are provided at the top of both sides inside the water tank. A filter screen is horizontally installed between the first slide rails. Using this prior art, the motor drives the drive shaft and drive wheel to rotate. The drive wheel drives the driven wheel and driven shaft to rotate together via a connecting belt, thereby causing the threaded screw to rotate simultaneously at the same speed. Simultaneously, the rotation of the threaded screw drives the threaded sleeve housing and the threaded sleeve to reciprocate up and down. This mechanized operation is fast and convenient, facilitating the cleaning of fishing nets.

[0004] However, the aforementioned existing technologies have the following technical defects:

[0005] The aforementioned existing technology requires the fishing nets to be first removed from the aquaculture area and placed on a fixed clamp. After securing the nets with clamps, the motor is started, driving the drive shaft and drive wheel to rotate. This drives the threaded screw to move the threaded sleeve housing and the threaded sleeve up and down in a reciprocating motion, causing the spraying device to move as well. A water pump draws water from the tank, which is then pressurized by a booster pump via a water pipe and finally sprayed out from the nozzles of the spraying device to clean the fishing nets. Before cleaning, the fishing nets need to be disassembled and fixed in the aforementioned device. The disassembly and installation of the fishing nets usually require manual operation, which can easily cause secondary pollution of the aquaculture water during the process of workers going into the water to disassemble the nets. Furthermore, the disassembly and installation of the fishing nets can also affect the normal progress of aquaculture.

[0006] Based on this, there is still room for improvement in the existing aquaculture net cleaning device to overcome the aforementioned technical defects. Summary of the Invention

[0044] The following is in conjunction with the appendix Figures 1-15 This application will be described in further detail.

[0045] This application discloses a marine aquaculture wastewater treatment device and process, which can collect aquaculture water in layers and perform rapid testing on the collected water. If the water quality does not meet the requirements, it can perform gradual automated cleaning without dismantling the aquaculture net, thus avoiding the impact of dismantling the entire aquaculture net on the aquaculture progress.

[0046] Reference Figure 1 and Figure 2 As shown, in a first aspect, this application provides a marine aquaculture wastewater treatment device, including a floating platform 1 and a propeller 11 installed on the underside of the floating platform 1. The propeller 11, when rotating forward and backward, can drive the floating platform 1 to move back and forth in the aquaculture area. A water pump 12 is installed on the upper side of the floating platform 1, and a treatment unit 2 is provided on the floating platform 1. When the floating platform 1 is placed in the aquaculture area, the treatment unit 2 can collect polluted water from the aquaculture area in layers and perform rapid testing on the collected water. When water that does not meet the requirements is detected, the aquaculture net in that depth area can be gradually and automatically cleaned. This eliminates the need for complete disassembly of the aquaculture net, ensuring the cleanliness of the aquaculture water without affecting the aquaculture progress.

[0047] The processing unit 2 includes a hollow tube 21 inserted into a floating platform 1. A through hole 101 is provided on the floating platform 1 for inserting the hollow tube 21. A U-shaped side seat 23 is mounted on one side of the floating platform 1 via two side clamps 22. The U-shaped side seat 23 is fixedly mounted on one side of the floating platform 1 via the two side clamps 22, and is located away from the hollow tube 21. A transmission pipe 24 connected to a water pump 12 is clamped on the outer wall of the U-shaped side seat 23. The water pump 12 has an inlet and an outlet. The transmission pipe 24 is connected to the inlet of the water pump 12. During use, an external connecting pipe needs to be connected to the outlet end, with the other end of the external connecting pipe placed outside the aquaculture area. Two tubular air bladders 26 are provided on the side wall of the floating platform 1 via two mounting plates 25. Inflating the tubular air bladders 26 increases the buoyancy of the floating platform 1 in the aquaculture area. The hollow tube 21 is equipped with a data acquisition and detection component 3, which is used to collect and quickly detect polluted water in layers; the U-shaped side seat 23 is equipped with a cleaning mechanism 4, which is used to gradually and automatically clean the aquaculture net.

[0048] In use, the floating platform 1 is placed in the aquaculture area, close to the edge of the aquaculture net. The hollow tube 21 is inserted into the through hole 101, allowing it to extend into the aquaculture area. The aquaculture net should be positioned in the middle of the U-shaped side seat 23. When the propeller 11 rotates, it drives the floating platform 1 to move on the water surface. The data collection and detection component 3 first performs stratified data collection and rapid detection on water at different depths. After detecting water that does not meet the requirements, the cleaning mechanism 4 can gradually and automatically clean the aquaculture net in that depth area.

[0049] Reference Figure 3 and Figure 4 As shown, in order to collect and detect polluted water at different depths, and to cooperate with the cleaning mechanism 4 to clean designated areas of the aquaculture net, the collection and detection component 3 includes five liquid storage bottles 31 arranged equidistantly within a hollow tube 21. All five liquid storage bottles 31 are fixedly installed within the hollow tube 21. A rectangular end block 32 is fitted at the upper end of the hollow tube 21, and a control rod 33 is slidably inserted into the rectangular end block 32. A rod hole 321 for inserting the control rod 33 is provided through the rectangular end block 32. In this embodiment, preferably, each of the five liquid storage bottles 31 has a U-shaped groove 311 adapted to the control rod 33 on its side wall, and an inlet hole 312 is provided at the U-shaped groove 311 of the liquid storage bottle 31. It should be noted that the upper end of the liquid storage bottle 31 is closed, and liquid can only enter the inner cavity of the liquid storage bottle 31 through the inlet hole 312. When the control rod 33 is driven, it can slide vertically and vertically at the U-shaped groove 311.

[0050] Reference Figure 5 and Figure 6As shown, since it is necessary to control water at different depths to enter the corresponding storage bottle 31 synchronously, this embodiment preferably has five access holes 331 equidistantly through the control rod 33, which are adapted to the inlet hole 312. Five rubber protrusions 34 are equidistantly installed on the side of the control rod 33 facing the storage bottle 31. It should be noted that each rubber protrusion 34 is located below each access hole 331, and the shape of the rubber protrusion 34 is adapted to the inlet hole 312. When the control rod 33 is at a certain height and the rubber protrusion 34 blocks the inlet hole 312, external liquid cannot enter the storage bottle 31. When the control rod 33 is driven to slide, causing the rubber protrusion 34 to disengage from the inlet hole 312, the rubber protrusion 34 can deform under pressure. A spring rod 35, connected to the bottom of a control rod 33, is installed inside the hollow tube 21. The spring rod 35 always has a driving force to push the hollow tube 21 upward, and the upward stroke is constant. When no other external force is applied, when the spring rod 35 pushes the hollow tube 21 to its highest position, five rubber protrusions 34 respectively seal the liquid inlet holes 312 on the five liquid storage bottles 31. The upper end of the hollow tube 21 has a hanging part 36, and a mounting plate 37 is provided on one side of the hanging part 36. A portable detector 38 is placed on the mounting plate 37, which can detect water.

[0051] When water needs to be collected, press down on the control rod 33 so that its upper end is flush with the upper side of the rectangular end block 32. At this time, the five access holes 331 on the control rod 33 coincide with the inlet holes 312 on the five storage bottles 31, thus opening the inlet holes 312. Water at different depths can then enter the storage bottles 31 through the inlet holes 312 at different depths, achieving a tiered water collection effect. After collection, release the control rod 33, which will slide upward and reset under the drive of the spring rod 35. The rubber protrusion 34 will re-seal the inlet hole 312. Then, pull up the hanging part 36 to remove the hollow tube 21. Use the portable detector 38 to quickly detect the water collected in each storage bottle 31.

[0052] Reference Figure 7 and Figure 8As shown, considering the need to clean the pollutants attached to the aquaculture net and to ensure the cleanliness of the aquaculture water without disassembling the entire aquaculture net and affecting the aquaculture progress, the cleaning mechanism 4 includes two rectangular covers 42 that are symmetrically limited and slidably installed on the inner wall of the U-shaped side seat 23 by the side square blocks 41. It should be noted that the two rectangular covers 42 have a certain distance to facilitate the placement of the floating platform 1 into the aquaculture water. When the aquaculture net is inside the U-shaped side seat 23, the upper edge of the aquaculture net is located between the two rectangular covers 42. The inner side of the U-shaped side seat 23 is symmetrically provided with rectangular sliding grooves 231 for the installation of the two square blocks 41. A folded flexible hose 43 connected to the transmission pipe 24 is installed on one side of the rectangular cover 42. The folded flexible hose 43 can be stretched under force.

[0053] A double-ended lead screw 44, threaded through a rectangular block 41, is rotatably mounted on a U-shaped side seat 23 located at a rectangular slide groove 231. The upper end of the double-ended lead screw 44 extends upward through the U-shaped side seat 23. An internal threaded hole 411, adapted to the double-ended lead screw 44, is provided through the rectangular slide groove 231. An extension hole 232, communicating with the rectangular slide groove 231 and allowing the upper end of the double-ended lead screw 44 to pass through, is provided on the U-shaped side seat 23. When the two double-ended lead screws 44 are driven to rotate, they can engage with the internal threaded hole 411 on the rectangular block 41 to drive the rectangular cover 42, causing it to extend downward into the aquaculture water and move upward to return to its original position.

[0054] Reference Figure 9 As shown, symmetrically rotatably mounted cylindrical supports 45 at both ends are installed inside a rectangular cover 42. The rectangular cover 42 has mounting holes 421 for the cylindrical supports 45. A cleaning roller 46 is positioned between the cylindrical supports 45, and the cylindrical supports 45 and the cleaning roller 46 are fixedly connected. The cleaning roller 46 has cleaning bristles 47. It should be noted that the cleaning bristles 47 are relatively long, allowing them to contact the aquaculture net when it is positioned between the two rectangular covers 42, even though there is a gap between them. When the cleaning roller 46 rotates under driving force, the cleaning bristles 47 can clean the contaminants adhering to the aquaculture net.

[0055] Reference Figure 9 and Figure 10 As shown, an end rod 48 is symmetrically and rotatably mounted on the U-shaped side seat 23. Symmetrically, the U-shaped side seat 23 has rotating holes 233 for mounting the end rod 48. A square control rod 49 is provided at the bottom of the end rod 48, penetrating the cylinder 45 and the cleaning roller 46. Both the cylinder 45 and the cleaning roller 46 have square holes 451 through which the square control rod 49 passes. The end rod 48 and the square control rod 49 are fixedly connected. When the end rod 48 is subjected to force and rotates, the square control rod 49 can drive the cylinder 45 and the cleaning roller 46 to rotate.

[0056] Reference Figure 11 As shown, in order to drive the two bidirectional lead screws 44 and the two end round rods 48 respectively, so that the two rectangular covers 42 can descend to different depths, and at the same time drive the cleaning rollers 46 installed inside the two rectangular covers 42 to rotate, a drive assembly 5 is provided on the U-shaped side seat 23. The drive assembly 5 includes a drive motor 51 mounted on the U-shaped side seat 23. The U-shaped side seat 23 has an inner groove 234 for mounting the drive motor 51. An end cover plate 52 is closed on the U-shaped side seat 23 at the inner groove 234. It should be noted that the rotation shaft of the drive motor 51 is set to penetrate the end cover plate 52 upwards; a drive gear 53 is sleeved on the rotating end of the drive motor 51. The drive motor 51 is hiddenly mounted on the U-shaped side seat 23.

[0057] Continue to refer to Figure 11 As shown, a lateral round rod 54 is rotatably mounted on the upper side of the end cover plate 52. A double-grooved wheel 55 and a ratchet 56 are sleeved on the lateral round rod 54, and the ratchet 56 meshes with the drive gear 53. A transmission belt 57 is sleeved between the double-grooved wheel 55 and the extended end of the double-direction screw 44. When the drive motor 51 rotates in the forward direction, it can drive the ratchet 56 to rotate through the drive gear 53, that is, drive the lateral round rod 54 and the double-grooved wheel 55 to rotate. The two transmission belts 57 sleeved on the double-grooved wheel 55 can drive the two double-direction screws 44 to rotate. When the water quality at a certain depth is detected to be unacceptable, the drive motor 51 is started to rotate in the forward direction, driving the two double-direction screws 44 to rotate, so as to synchronously drive the two rectangular covers 42 to slide downward and extend into the corresponding depth in the aquaculture water. At this time, due to the downward movement of the two rectangular covers 42, the folded hose 43 will be stretched, and the two rectangular covers 42 are respectively located on both sides of the aquaculture net.

[0058] Reference Figure 12 As shown, a lateral round rod 58 is rotatably mounted on the upper side of the end cover plate 52. A double-grooved wheel 59 and a ratchet 591 are sleeved on the lateral round rod 58, and the ratchet 591 meshes with the drive gear 53. A transmission belt 592 is sleeved between the double-grooved wheel 59 and the end round rod 48. After the two rectangular covers 42 are driven to descend to the corresponding depth, the drive motor 51 is started to rotate in the opposite direction. At this time, the drive gear 53 can drive the ratchet 591 to rotate, that is, drive the lateral round rod 58 and the double-grooved wheel 59 to rotate. The two transmission belts 592 sleeved on the double-grooved wheel 59 can drive the two end round rods 48 to rotate. Under the drive of the square control rod 49 installed at the lower end of the two end round rods 48, the end cylinder 45 and the cleaning roller 46 rotate. The cleaning brush bristles 47 on the cleaning roller 46 can clean the pollutants attached to the breeding net. At the same time, the water pump 12 is started to pump out the sewage in the rectangular cover 42 area through the folded hose 43 and discharge it to the outside of the aquaculture water area through the external pipe.

[0059] Reference Figure 13 and Figure 14 As shown, based on Embodiment 1, in order to limit the pollutants originally attached to the aquaculture net during cleaning, so that they can be contained within the two rectangular covers 42 and then extracted by the water pump 12, the pollutants are prevented from being dispersed to other areas. The rectangular cover 42 is also provided with an extension unit 6 that cooperates with the rotating end-abutting cylinder 45. The extension unit 6 includes a telescopic frame 61 installed on one side of the rectangular cover 42. The telescopic frame 61 is softly folded and can expand outward when subjected to force. Side rollers 62 are symmetrically rotatably installed on the telescopic frame 61. Protrusions 63 are symmetrically arranged on the telescopic frame 61. The side of the protrusions 63 facing the inner cavity of the rectangular cover 42 is provided with a pushing ball 65 through a cylindrical seat 64. The two end-abutting cylinders 45 located inside the rectangular cover 42 are fitted with protruding wheels 66 that cooperate with the pushing balls 65. The protruding wheels 66 are fixedly fitted on the end-abutting cylinders 45. When the end-abutting cylinders 45 are driven to rotate, the protruding wheels 66 can rotate synchronously.

[0060] A U-shaped frame rod 67 is fixedly sleeved on the cylindrical base 64. Two limiting round rods 68 are slidably inserted into the U-shaped frame rod 67, and one end of the limiting round rods 68 is fixedly connected to the inner side wall of the rectangular cover 42. A return spring 69 is sleeved on the limiting round rods 68. The return spring 69 always has a driving force to push the U-shaped frame rod 67 towards the inner cavity of the rectangular cover 42. That is, without other external forces, the telescopic frame 61 is always in a retracted state. At this time, although the telescopic frame 61 and the side roller 62 are installed at the opening of the two rectangular covers 42, there is still a certain gap between the two rectangular covers 42 to ensure that the upper edge of the aquaculture net can be between the two rectangular covers 42 when the equipment is placed. It should be noted that in the initial state, driven by the return spring 69, the ball bearing 65 is pushed into the recess of the protruding wheel 66, so that the telescopic frame 61 is in a retracted state.

[0061] Because the two rectangular covers 42 have a certain distance between them, pollutants cleaned from the aquaculture net are easily dispersed and flow out of the coverage area of ​​the rectangular covers 42, and cannot be pumped out by the water pump 12. This means that when cleaning the aquaculture net, it will also cause secondary pollution to the aquaculture water area. Therefore, it is necessary to prevent pollutants from flowing out of the rectangular covers 42. When the end abutment cylinder 45 and the cleaning roller 46 are driven to rotate, it means that the aquaculture net is being cleaned. The protruding wheel 66 rotates quickly with the end abutment cylinder 45. The protrusion of the protruding wheel 66 can drive the pushing ball 65 to move towards the middle of the two rectangular covers 42, thereby driving the telescopic frame 61 to extend outward, so that one side of the telescopic frame 61 can abut against the aquaculture net to prevent pollutants from flowing out of the rectangular covers 42. The side roller 62 can reduce the friction effect when the telescopic frame 61 contacts the aquaculture net when the propeller 11 drives the floating platform 1 to move, thereby driving the U-shaped side seat 23 to move as a whole.

[0062] Reference Figure 15 As shown, this application also discloses a marine aquaculture wastewater treatment process, which includes the following steps:

[0063] S1, Equipment Placement: In use, place the floating platform 1 in the aquaculture area, so that the hollow pipe 21 is in the aquaculture water and the aquaculture net is inside the U-shaped side seat 23; the upper edge of the aquaculture net is located between the two rectangular covers 42. Connect the outer pipe to the drain port of the water pump 12, and place the other end of the outer pipe outside the aquaculture area.

[0064] S2, Data Collection and Detection: The data collection and detection component 3 on the hollow tube 21 collects data from the aquaculture water in layers and performs rapid detection on the collected water. Specifically, during collection, the control rod 33 is pressed down so that the inlet hole 331 on the control rod 33 coincides with the liquid inlet hole 312, and the water enters the storage bottle 31 through the liquid inlet hole 312. After collection, the rubber protrusion 34 of the control rod 33 is released to reseal the liquid inlet hole 312, and the hollow tube 21 is pulled out upwards. The water collected in the storage bottle 31 is then rapidly detected using the portable detector 38.

[0065] S3, Mobile Cleaning: After detecting water bodies that do not meet the requirements, the cleaning mechanism 4 on the U-shaped side seat 23, in conjunction with the propeller 11, drives the floating platform 1 to automatically clean the aquaculture net in this area. When the water quality at a certain depth is found to be unacceptable, the drive motor 51 is started to rotate forward, driving the two rectangular covers 42 to descend to the corresponding depth in the aquaculture water. Then, the drive motor 51 is controlled to rotate in the reverse direction, so that the drive end rotates against the cylinder 45 and the cleaning roller 46, and the cleaning brushes 47 on the cleaning roller 46 clean the contaminants on the aquaculture net.

[0066] S4, Debris Removal: Simultaneously, the water pump 12 works in conjunction with the cleaning mechanism 4 to remove contaminants generated during cleaning, preventing them from remaining in the aquaculture area. When the end-abutting cylinder 45 and the cleaning roller 46 rotate, the protruding wheel 66 rotates rapidly along with the end-abutting cylinder 45. Through contact with the pushing ball 65, it drives the telescopic frame 61 to expand outward. One side of the telescopic frame 61 contacts the aquaculture net, and the water pump 12 starts to extract the sewage from the rectangular cover 42 area and discharge it to the outside of the aquaculture area through the external pipe.

[0067] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
