Description

Technical Field

[0001] The present invention relates to the technical field of ecological management, and in particular to an off-site ecological management device for aquaculture pond water. Background Art

[0002] When treating tailwater from aquaculture ponds, large drainage channels can be used as ecological channels where conditions permit, and aquatic plants can be planted or floating beds can be set up in the channels. Ecological channels such as slope protection should adopt ecological slope protection, and excessive hardening of slope protection is prohibited to avoid destroying the natural ecological purification effect. Appropriate hardening of slope protection can be adopted in areas susceptible to water flow impact.

[0003] A large amount of tail water is generated during aquaculture, and the tail water contains toxic and harmful substances produced by aquatic organisms. At present, in most cases, farms use bio-balls or filters to perform preliminary filtration and treatment of tail water. However, the water in aquaculture ponds contains a large amount of suspended impurities such as leftover bait, feces, silt and remains of aquatic organisms, which are easily accumulated on the surface and pores of the filter medium, requiring frequent backwashing operations. Backwashing not only consumes additional water resources, but may also affect the continuous operation of the entire treatment device. If it is not cleaned in time, the filtration system may even fail completely, resulting in poor treatment effect. In addition, a large number of microbial films will adhere to the surface of the filter medium after long-term use, further affecting the filtration effect.

[0020] The beneficial effects of the present invention are:

[0021] 1. During the use of the equipment, the pool water can be sent into the filter box through a water pump, and the filter cartridge can be driven by a motor to rotate to complete the primary filtration of the pool water. At the same time, the scraper can scrape off the impurities filtered on the surface of the filter cartridge to reduce the blockage of the filter cartridge surface and ensure the filtration effect. The pool water filtered by the filter cartridge falls to the bottom of the filter box and flows to the inside of the carrier frame through the drainage slot holes, waiting for subsequent processing. After that, the air is sent into the aeration pipe through the aerator, and the air is discharged from the aeration hole into the pool water through the stirring plate, thereby oxygenating it. The dissolved oxygen content in the water is quickly increased through aeration, creating a suitable living environment for microorganisms, so that they can efficiently decompose the remaining organic matter in the water.

[0022] 2. When the motor drives the filter cartridge to rotate, it also drives the lever to rotate. As the lever rotates, the baffle plate is squeezed, thereby driving the movable plate to move toward the side of the drain pipe. At the same time, the baffle plate squeezes the reset spring during the movement of the movable plate, and the meshing connection between the teeth and the gear plate can drive the aeration pipe to rotate, thereby stirring the pool water through the stirring plate. Stirring can make the injected air bubbles more evenly distributed in the water, accelerate the contact area and frequency of air and water, and promote the faster transfer of oxygen from the bubbles to the water body, providing sufficient power for the subsequent aerobic microorganisms to decompose pollutants.

[0023] 3. When the surface of the filter cartridge is covered with a lot of biofilm and cannot be scraped and cleaned by the scraper, the filtration speed decreases and the amount of pool water accumulated above the filter box increases. As the water level rises, the buoyancy ball will move up and the lifting rod will move upward. When the water level reaches a certain position, the lifting rod will squeeze the pressure sensor. Through the work of the booster pump, the liquid can be sprayed into the interior of the filter box through the connecting pipe, thereby decomposing the microbial film and preventing the microbial film from continuing to adhere to the surface of the filter cartridge. Gentle cleaning is achieved to ensure the filtration effect, which is beneficial to the cleaning of the filter cartridge and ensures the water quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0036] Embodiment 1, refer to Figure 1-Figure 9 , an ex situ ecological management device for aquaculture pond water, comprising a bearing frame 1 and a water pump 3, a detector 7 and a water pump 8 are arranged on the upper end of the bearing frame 1, the bearing frame 1 is connected with a drain pipe 9, and further comprising:

[0037] A filter assembly 2, the filter assembly 2 is fixedly connected to the carrier frame 1, and the filter assembly 2 is used for primary filtering of pool water;

[0038] A cleaning component 4, the cleaning component 4 is located above the filter component 2, and the cleaning component 4 is used to clean the filter component 2;

[0039] An aeration assembly 6, the aeration assembly 6 is connected to the supporting frame 1, and the aeration assembly 6 is used for secondary treatment of the filtered pool water;

[0040] The transmission assembly 10 is connected to the supporting frame 1 , and is used to promote the aeration assembly 6 to treat the pool water.

[0041] Furthermore; the filter assembly 2 includes a filter box 21, a filter cartridge 24 and a lever 241, the filter box 21 is fixedly connected to one end of the carrier frame 1, the inner wall of the filter box 21 is fixedly connected with a scraper 23, two scrapers 23 are provided, the two scrapers 23 are located on both sides of the outer wall of the filter cartridge 24 symmetrically, and the two ends of the filter cartridge 24 are rotatably connected to the side wall of the filter box 21; the side wall of the filter box 21 is fixedly connected with a motor 11, the motor 11 is fixedly connected to one end of the filter cartridge 24, the end of the filter cartridge 24 away from the motor 11 passes through the side wall of the filter box 21 and is fixedly connected to the lever 241, and the side wall of the filter box 21 is provided with a drainage slot 22, and the drainage slot 22 is located below the filter cartridge 24; one end of the water pump 3 is fixedly connected to a water inlet pipe 32, and the other end of the water pump 3 is fixedly connected to a water supply pipe 31, and the end of the water supply pipe 31 away from the water pump 3 is fixedly connected to the filter box 21.

[0042] Primary filtration of pool water by the filter assembly 2: During the use of the equipment, it can be installed at a suitable position around the pond, the water inlet pipe 32 can be placed above the water surface, and a liquid level sensor can be set on the side wall of the water inlet pipe 32. The liquid level sensor is used to detect the height of the pool water level to avoid the liquid level being too high and affecting the breeding conditions. When the liquid level sensor detects that the pool water level is too high, the electrical signal connection between the liquid level sensor and the water pump 3 can be used to make it work, and the pool water can be sent to the interior of the filter box 21 through the water inlet pipe 32 and the water delivery pipe 31. In addition, it can also be manually operated according to the actual situation. Operation, when the pool water enters the filter box 21, the motor 11 is started and drives the filter cartridge 24 to rotate, and the impurities in the pool water are primarily filtered through the filter cartridge 24. During the rotation of the filter cartridge 24, the impurities filtered on the surface of the filter cartridge 24 can be scraped off by the scraper 23, reducing the blockage on the surface of the filter cartridge 24 and ensuring the filtering effect. The pool water filtered by the filter cartridge 24 falls to the bottom of the filter box 21 and flows to the inside of the supporting frame 1 through the drainage slot 22, waiting for subsequent secondary processing. The bottom of the filter box 21 is arranged in an inclined surface to facilitate the rapid discharge of the filtered pool water.

[0043] Reference Figure 2 , Figure 3 , Figure 8 and Fig. 9, further; the aeration assembly 6 includes an aerator 61 and an aeration pipe 62, the aerator 61 is fixedly connected to the side wall of the carrier frame 1, a plurality of aeration pipes 62 are provided, and the plurality of aeration pipes 62 are distributed in a linear array inside the carrier frame 1, one end of the aeration pipe 62 is connected to the aerator 61, the aeration pipe 62 is rotatably connected to the carrier frame 1, the other end of the aeration pipe 62 is fixedly connected to a rotating rod 65, the rotating rod 65 is rotatably connected to the side wall of the carrier frame 1, the outer wall of the rotating rod 65 is fixedly connected to a gear plate 64, the gear plate 64 is located on the outer side of the carrier frame 1, the outer wall of the aeration pipe 62 is fixedly connected to a plurality of stirring plates 63 distributed in a circumferential array, and an aeration hole 631 is provided at one end of the stirring plate 63 away from the aeration pipe 62;

[0044] The aeration component 6 performs secondary treatment on the filtered pool water: after the pool water after primary filtration enters the interior of the supporting frame 1, the aerator 61 can be started to send air into the interior of the aeration pipe 62. Because the stirring plate 63 is connected to the aeration pipe 62, the air can be discharged from the aeration hole 631 into the pool water, thereby oxygenating it. Although the aquaculture pond water after primary filtration has removed some pollutants and impurities, it still needs to rely on microorganisms to continuously decompose the remaining organic impurities to maintain water quality stability. The respiration and metabolic activities of microorganisms rely on oxygen. Aeration can quickly increase the dissolved oxygen content in the water, create a suitable living environment for microorganisms, and enable them to efficiently decompose the remaining organic matter in the water, such as small molecular organic matter produced by the decomposition of leftover bait and feces, to further purify the water quality. If the treated water is to be returned to the aquaculture pond for use, sufficient dissolved oxygen is essential for aquatic animals such as fish, shrimps and crabs in the pond. Aquatic organisms absorb dissolved oxygen in the water through their gills to maintain life activities. When the dissolved oxygen is sufficient, they feed and grow more actively, their body immunity is enhanced, the probability of disease occurrence is reduced, and the aquaculture efficiency is improved.

[0045] Furthermore, the transmission assembly 10 includes a fixed plate 104 and a movable plate 107, the fixed plate 104 is fixedly connected to the side wall of the carrier frame 1, a sliding bar 105 is fixedly connected to one side of the movable plate 107, and the sliding bar 105 is arranged in a "T" shape. One end of the movable plate 107 is fixedly connected to a plurality of teeth 106 distributed in a linear array, and the teeth 106 are meshed with the gear plate 64; a baffle 101 is fixedly connected to the side wall of the movable plate 107, and a return spring 102 and a sliding rod 103 are arranged on one side of the baffle 101, and the sliding rod 103 is arranged in a "T" shape, and one end of the sliding rod 103 passes through the side wall of the fixed plate 104 and is fixedly connected to the baffle 101 The return spring 102 is sleeved on the outer wall of the slide rod 103, and the two ends of the return spring 102 are fixedly connected to the side walls of the baffle 101 and the fixed plate 104 respectively; a slide groove 13 is provided on the side wall of the supporting frame 1, and the slide groove 13 and the slide bar 105 slide in a limited manner. One end of the supporting frame 1 is fixedly connected to a support plate 12, and the upper side walls of the support plate 12 are respectively fixedly connected to the detector 7 and the water pump 8, one end of the water pump 8 is fixedly connected to a water suction pipe 5, and the other end of the water pump 8 is fixedly connected to a reflux pipe 81, and the end of the water suction pipe 5 away from the water pump 8 is located inside the supporting frame 1, and the end of the supporting frame 1 away from the filter box 21 is fixedly connected to a drain pipe 9.

[0046] The linkage between the transmission assembly 10 and the lever 241 can be as follows: Figure 1As shown, the motor 11 drives the filter cartridge 24 to rotate and drives the lever 241 to rotate, and the filter cartridge 24 drives the lever 241 to rotate counterclockwise, and in the initial state, the baffle 101 is located on one side of the lever 241. At this time, as the lever 241 rotates, it can squeeze the baffle 101, and the movable plate 107 can move to the side of the drain pipe 9 through the limited sliding between the slide groove 13 and the slide bar 105, and its stability during the movement is guaranteed. At the same time, in this process, the baffle 101 squeezes the reset spring 102, and the slide bar 103 and the fixed plate 10 4 is connected to ensure the stability of the return spring 102 during compression and avoid bending of the return spring 102. During the movement of the moving plate 107, the meshing connection between the teeth 106 and the gear plate 64 can drive the aeration pipe 62 to rotate, so that the pool water is stirred through the stirring plate 63. The stirring can make the injected air bubbles more evenly distributed in the water, accelerate the contact area and contact frequency between air and water, and promote the faster transfer of oxygen from the bubbles to the water body. For example, when there is no stirring, the bubbles may quickly float to the water surface and burst. The bubbles will escape and take away a large amount of undissolved oxygen, and the turbulent water flow generated by stirring will cut the bubbles into smaller sizes, prolong their residence time in the water, and allow more oxygen to dissolve in the water, providing sufficient "power" for the subsequent aerobic microorganisms to decompose pollutants; and the aerobic microorganisms will produce metabolites such as carbon dioxide and water when decomposing pollutants. Stirring is conducive to the rapid diffusion of these products from around the microorganisms. If the metabolites accumulate, the activity of the microorganisms themselves will be inhibited, and the decomposition speed will be slowed down. Timely diffusion will remove this inhibition, allowing the microorganisms to continuously and quickly purify the remaining pollutants in the sewage. In addition, when the lever 241 is separated from the baffle 101, the reset spring 102 is no longer subjected to external pressure, and can drive the moving plate 107 to reset through its own elastic recovery, waiting for the next movement. Through this reciprocating motion, the aeration pipe 62 can drive the stirring plate 63 to stir the pool water, promote the secondary treatment of the aeration assembly 6, and during the reset process of the reset spring 102, the resistance and limit effect can prevent it from vibrating back and forth, so as to ensure that it can be restored to stability when the baffle 101 is squeezed next time.

[0047] Utilization of treated pond water: The treated pond water can be tested by the detector 7. When the test meets the standard, the valve on the drain pipe 9 can be opened to discharge the pond water, and the treated water can be returned to the pond to realize the recycling of water resources, reduce the use of new water, and reduce the breeding cost. As long as the water quality meets the pond breeding water standard after treatment, such as removing harmful pollutants and restoring the appropriate dissolved oxygen and pH, the return water can replenish the pond water volume, maintain a stable breeding environment, avoid the stress problem caused by frequent water changes, and also help maintain the continuity of the pond ecology; In addition, the aquaculture wastewater that has been treated to meet the standards contains nutrients such as nitrogen and phosphorus, which are nutrients required for the growth of crops. The filtered pool water can be led to the surrounding farmland to provide fertility for crops and realize the resource utilization of waste. However, before discharge, it is necessary to ensure that there are no pesticide residues, antibiotics and excessive heavy metals in the wastewater, otherwise it will pollute the soil and affect the quality and safety of agricultural products. If the pool water does not meet the standards, the water pump 28 can be started to transport the pool water back to the inside of the filter box 21 through the suction pipe 5 and the return pipe 81 for secondary filtration treatment to ensure the treatment quality of the pool water.

[0048] Example 2, refer to Figure 1 , Figure 2 and Figure 4 , further; the filter assembly 2 also includes a lifting rod 25 and a buoyancy ball 26, the lifting rod 25 is arranged in a "T" shape, the lifting rod 25 is slidably connected to the upper side wall of the filter box 21, and the end of the lifting rod 25 located inside the filter box 21 is fixedly connected to the buoyancy ball 26; the cleaning assembly 4 includes a storage box 42, one end of the storage box 42 is fixedly connected to a booster pump 41, and the lower side wall of the storage box 42 is fixedly connected to a plurality of connecting pipes 43, wherein a pressure sensor 44 is provided between two connecting pipes 43, and the pressure sensor 44 is fixedly connected to the lower end of the storage box 42, and the pressure sensor 44 is located directly above the lifting rod 25.

[0049] Cleaning of the filter cartridge 24 by the cleaning component 4: When the surface of the filter cartridge 24 is covered with a large amount of biofilm and cannot be scraped and cleaned by the scraper 23, its filtration speed decreases. At the same time, the amount of water delivered by the water pump 3 is constant, so the amount of pool water accumulated above the filter box 21 will increase. As the water level rises, the buoyancy ball 26 will be driven to move upward, and the lifting rod 25 will be driven to move upward. When the water level reaches a certain position, the lifting rod 25 will squeeze the pressure sensor 44, and the pressure sensor 44 is electrically connected to the booster pump 41, and the storage box 42 is filled with beneficial microbial preparations or other related reagents. Through the operation of the booster pump 41, the liquid can be sprayed into the interior of the filter box 21 through the connecting pipe 43, and the connecting pipe 43 is a one-way water spray pipe. The beneficial microbial preparation can be Bacillus or other strains. When it is put into the filter box 21, they compete with harmful microorganisms that form biofilms for nutrients and living space, and inhibit the growth of harmful biofilms. In the process of metabolism, Bacillus will also secrete a variety of enzymes to decompose extracellular polymers, polysaccharides and other components in the microbial membrane, allowing The membrane structure is loose, so as to prevent the microbial film from continuing to adhere to the surface of the filter cartridge 24, achieve gentle cleaning, and be washed away with the water flow to ensure the filtering effect. Moreover, Bacillus itself is non-toxic and harmless, and will not change the basic chemical properties of the pond water. The metabolites are mostly carbon dioxide, water, etc., which do not cause water pollution. In addition, other related reagents can be surfactants, whose special molecular structure can reduce the surface tension of water, penetrate between the biofilm and the attached surface, and play the role of emulsifying and dispersing the biofilm, which is convenient for subsequent washing away with water. Mild surfactants are also suitable for cleaning biofilm stains on the surface of farmed fish and shrimp. Surfactants can be natural and easily degradable surfactants. Strictly controlling the dosage each time it is used can be beneficial to cleaning the filter cartridge 24 and ensuring the water quality. The buoyancy ball 26 can be made of plastic products, such as polyethylene (PE), but is not limited to this. Polyethylene is light, has good chemical stability, strong corrosion resistance, can be used for a long time in various chemical environments such as acids, alkalis, and salts, is not easy to react chemically, and has relatively low cost.

[0050] It should be noted that the specific models and specifications of the motor, water pump and other components need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
