Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aquaculture, in particular to a filtering component for aquaculture water treatment. Background Art
[0002] In modern aquaculture, water quality management is one of the key factors to ensure the healthy growth of aquaculture organisms and improve aquaculture benefits. Harmful substances such as ammonia nitrogen often accumulate in aquaculture water. If these substances are not removed in time, they will seriously affect the living environment of aquatic organisms, causing diseases and even death. Therefore, the development of efficient and durable water filtration materials is crucial to maintaining good aquaculture water quality.
[0003] Traditional water filtration technology mainly relies on plastic fillers, which are designed with complex porous structures. The purpose is to encourage nitrifying bacteria to form a biofilm on their surface (film formation phenomenon) as water slowly flows through the porous gaps, thereby utilizing the biological action of nitrifying bacteria to degrade harmful substances such as ammonia nitrogen in the water. Although such materials have improved water treatment efficiency to a certain extent, they also have some inherent limitations. For example, as the thickness of the biofilm increases, the weight of the filler increases, resulting in a slower flow rate, reducing the effective contact area between the water body and the biofilm, and thus reducing the rate of nitrification. In addition, some improved products on the market have tried to add filter cotton inside the plastic filler to increase the attachment area of nitrifying bacteria, but this has not fundamentally solved the problem of limited water flow. Instead, it may have exacerbated the poor water flow due to material blockage. Utility Model Content

[0031] In modern aquaculture, water quality management is one of the key factors to ensure the healthy growth of aquaculture organisms and improve aquaculture benefits. Harmful substances such as ammonia nitrogen often accumulate in aquaculture water. If these substances are not removed in time, they will seriously affect the living environment of aquatic organisms, causing diseases and even death. Therefore, the development of efficient and durable water filtration materials is crucial to maintaining good aquaculture water quality.
[0032] Traditional water filtration technology mainly relies on plastic fillers, which are designed with complex porous structures. The purpose is to encourage nitrifying bacteria to form a biofilm on their surface (film formation phenomenon) as water slowly flows through the porous gaps, thereby utilizing the biological action of nitrifying bacteria to degrade harmful substances such as ammonia nitrogen in the water. Although such materials have improved water treatment efficiency to a certain extent, they also have some inherent limitations. For example, as the thickness of the biofilm increases, the weight of the filler increases, resulting in a slower flow rate, reducing the effective contact area between the water body and the biofilm, and thus reducing the rate of nitrification. In addition, some improved products on the market have tried to add filter cotton inside the plastic filler to increase the attachment area of nitrifying bacteria, but this has not fundamentally solved the problem of limited water flow. Instead, it may have exacerbated the poor water flow due to material blockage.
[0033] For this reason, Figure 1 and Figure 2As shown, a filter assembly for aquaculture water treatment proposed by the utility model includes a bio-house 100 and a ceramic ring 200 installed in the bio-house 100, wherein the bio-house 100 is a plastic part and the ceramic ring 200 is a ceramic part. In some embodiments, the bio-house 100 adopts a plastic biofilm culture formula, and the material that promotes biofilm is integrated into the plastic, and nitrifying bacteria easily stay on the plastic surface, so that it is easy to form a biofilm. In addition, the bio-house 100 is a hollow structure 101, which can allow liquid to pass through and form a biofilm; the ceramic ring 200 is a hollow structure, which can allow liquid to flow through the ceramic ring 200. It should be noted that the plastic bio-house 100 that promotes biofilm is combined with the hollow ceramic ring 200 to achieve water flow optimization. The ceramic ring 200 with a hollow structure design is conducive to water flow, and the phenomenon of dead water is eliminated. It is much better than the use effect of Tibetan filter cotton, solves the problem of slowing down the water flow of traditional filter materials and reducing the contact area, greatly improves the biodegradation efficiency of harmful substances such as ammonia nitrogen, and ensures the continuous purification ability of water quality.
[0034] Refer to Figure 1 and Figure 2 , the bio-house 100 is spherical, so that the entire filter assembly can roll freely in the water, increase the contact opportunity between the water flow and its surface, and then promote the water flow to be more evenly distributed in each part of the bio-house 100, and improve the overall mass transfer efficiency. The spherical design also helps to avoid dead corners, reduce water stagnation areas, create a more dynamic water flow environment, which is conducive to the activity and biofilm effect of nitrifying bacteria and improves the water purification efficiency. Optionally, the diameter of the bio-house 100 is A, and the length of the ceramic ring 200 is B, which satisfies: 0.67*A≤B≤A. The appropriate filling degree of the ceramic ring 200 in the bio-house 100 and the optimal path of the water flow are ensured, and the internal space of the bio-house 100 will not be congested due to the excessive length of the ceramic ring 200, nor will it be too short to reduce the filtration efficiency. Such a size ratio is conducive to maintaining an ideal hydrodynamic state, further optimizing the growth environment and biofilm process of nitrifying bacteria, thereby improving the removal rate of harmful substances such as ammonia nitrogen. In addition, in some embodiments of the present invention, the hollow structure 101 is a mesh-like gap structure arranged on the surface of the biological house 100, which greatly increases the contact area with the water body, allowing the water flow to pass through each gap more smoothly, promoting the rapid formation and stable maintenance of the microbial film. This structure not only helps to improve the flow efficiency of the water body and reduce resistance, but also provides a wider attachment point for nitrifying bacteria, enhances the biodegradation efficiency, and thus improves the water purification ability. It is easy to understand that the surface of the sphere is designed into a mesh-like gap structure according to the tangent of the water flow, which allows the water flow to easily flow through each gap and easily produce a bacterial film.
[0035] Furthermore, the overall density of the bio-house 100 and the ceramic ring 200 after being combined is C, and the density of water is D, which satisfies: 0.9≤C / D≤1.1, so that the filter assembly can achieve an ideal suspension state in the water, neither sinking too much nor floating too much, ensuring the natural circulation and full contact of the water flow. Specifically, C / D is close to 1, and the filter assembly can be suspended in the water and can continuously roll with the water flow in the water. This design helps to maintain the flow dynamics balance of the water body, so that the filter material can achieve the best filtering effect at any position, and also simplifies the installation and maintenance operations of the equipment.
[0036] In addition, in some embodiments of the utility model, the ceramic ring 200 is a porous structure. Specifically, the porous structure is an ultra-fine pore set in the ceramic ring 200, so that the water absorption rate of the ceramic ring 200 reaches 40%, which significantly increases its surface area, provides more habitats for nitrifying bacteria, is conducive to the implantation and growth of nitrifying bacteria, promotes the rapid reproduction and efficient metabolism of bacteria, and thus accelerates the biological transformation process of harmful substances such as ammonia nitrogen. In addition, the high porosity also helps to enhance the permeability of the water body, reduce water flow resistance, and ensure the efficient operation of the filtration system.
[0037] In some embodiments of the present invention, the bio-house 100 is provided with a fixing structure to fix the ceramic ring 200, thereby ensuring the stability and positioning accuracy of the ceramic ring 200 during use, preventing the ceramic ring 200 from being displaced or falling off due to water flow impact or equipment vibration, and ensuring the long-term stable operation of the filtration system and the continuous water purification effect. Figure 1The fixing structure includes a clamping block 110, which is arranged on the biological house 100. The clamping block 110 is clamped and fixed with the ceramic ring 200. The structure is simple and the connection is firm. It is not only convenient for assembly and disassembly, but also ensures that the ceramic ring 200 is stable and does not fall off during the filtration process, avoiding the reduction of system efficiency caused by material movement, and enhancing the reliability and durability of the system. Further, there are multiple clamping blocks 110, and multiple clamping blocks 110 are arranged in a circumferential array. Multiple clamping blocks 110 are suitable for deforming inwardly so that the ceramic ring 200 can be inserted inwardly and abut against the inner wall of the ceramic ring 200. The bottom of the clamping block 110 is provided with a blocking protrusion 111 to prevent the ceramic ring 200 from detaching outward. Through the circumferential array arrangement and deformable design of the clamping block 110, the fixing effect is further improved, ensuring that the ceramic ring 200 can still fit tightly when subjected to water flow pressure, reducing potential water flow leakage channels, improving the integrity and efficiency of filtration, and simplifying maintenance operations and reducing maintenance costs. For example, there are three clamping blocks 110, and the three clamping blocks 110 and the blocking protrusions 111 together form three bayonet positions to firmly clamp the ceramic ring 200, which is not easy to cause the ceramic ring 200 to roll over and collide in the water and fall off. Optionally, the clamping block 110 is a plastic part, and the clamping block 110 and the biological house 100 are integrally injection molded, which not only enhances the stability of the overall structure, but also simplifies the production process, reduces the number of parts, and reduces the manufacturing cost. This integrated design also avoids gaps between parts, reduces potential bacteria breeding points, and further improves the safety and sanitation level of water treatment.
[0038] In application, refer to Figure 3 The biological house 100 has a larger opening on one side facing the blocking protrusion 111, and water can flow into the biological house 100 from the opening, and can flow into the inner cavity of the ceramic ring 200 from one end of the ceramic ring 200, and then flow out from the other end of the ceramic ring 200, or the water flows out from the peripheral wall of the ceramic ring 200. Compared with the existing filter components with filler designs, the design of flowing through the ceramic ring 200 is more conducive to the cultivation of nitrifying bacteria.
[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
