Description

Technical Field

[0001] This application belongs to the field of water treatment technology, specifically a device with interchangeable permeable holes. Background Technology

[0002] In current large-scale recirculating aquaculture systems, the exchange of water between the tank and the reservoir relies primarily on permeable holes in the tank walls to circulate the external water flow. However, different stages of aquaculture, fish sizes, water flow rates, and escape prevention requirements necessitate varying sizes, shapes, and densities of these permeable holes. Traditional tanks have fixed permeable holes that cannot be adjusted or replaced as needed, easily leading to excessive water inflow or poor drainage, and even risks such as small fish escaping and disease transmission.

[0003] The replaceable design of this device significantly extends its service life because changing the orifice diameter avoids performance degradation caused by orifice blockage or excessive wear. Its simple structure and ease of maintenance reduce the risk of equipment failure and downtime, improving overall efficiency.

[0004] However, common problems include the inability to standardize replacements for different aquaculture needs, resulting in poor system flexibility; the inability to quickly close or replace systems also hinders stress management and disease control. Utility Model Content

[0005] The purpose of this application is to provide a device that allows for the replacement of permeable holes, in order to solve the aforementioned problem of achieving standardized replacement.

[0006] The technical solution adopted in this application is as follows: A device with replaceable water-permeable hole size includes a filter structure body, the filter structure body has multiple water-filtering tanks inside, a sealing plate is snapped into the inside of the water-filtering tanks, multiple snap-fit ​​plates are fixedly connected to the side of the sealing plate, the snap-fit ​​plates are threadedly connected to connecting bolts, the other end of the connecting bolts passes through the threaded holes inside the filter structure body, a sealing gasket is provided in the middle position of the sealing plate and the filter structure body, and multiple water-filtering plates, including water-filtering plate one and water-filtering plate two, are provided at the lower end of the sealing plate.

[0007] By adopting the above technical solution, the use of snap-fit ​​plates and connecting bolts facilitates the replacement of the sealing plate by operators during equipment operation. This allows for adjustment and replacement of the filter plate size at the lower end of the sealing plate according to different operational needs, thus meeting the water treatment requirements at different stages. During use, the sealing gasket strengthens the connection and seal between the sealing plate and the filter structure body, ensuring the airtightness of the structural components and facilitating subsequent operations. Connecting bolts inserted into the handle fix the sealing plate within the filter tank of the filter structure body, ensuring component stability. The use of multiple filter tanks and different filter plates (one and two) ensures the structure's water filtration efficiency. This design facilitates subsequent operations and allows for easy replacement of filter plates with different pore sizes through the setting of results. Workers quickly replace the filter plates with those of different pore sizes by inserting the snap-fit ​​plate on the side of the sealing plate into the main body of the filter structure, inserting the connecting bolt into the snap-fit ​​plate, and then connecting it to the threaded hole inside the filter structure to fix the snap-fit ​​plate in place and ensure the stability of the sealing plate. When disassembly is needed, the connecting bolt is removed to release the restriction on the sealing plate, allowing for its removal and replacement. Furthermore, this structure allows for the replacement of filter plates with larger pore sizes as the fish grow and the actual water flow and circulation needs are met, enhancing water exchange capacity. If disease is detected or temporary isolation is required, a sealing plate can be inserted to temporarily stop water exchange and facilitate disinfection.

[0012] In a preferred embodiment, a plurality of rectangular plates are fixedly connected to the interior of the outer frame plate, and a plurality of fixing plates are fixedly connected to the side of the outer frame plate.

[0013] By adopting the above technical solution, the permeability of the structure is ensured by setting multiple rectangular plates, which facilitates subsequent installation and fixing in the work area. The outer frame plate can be easily fixed in the designated work area by using fixing screws.

[0014] In a preferred embodiment, a water inlet is provided on the side of the filter structure body opposite to the connecting plate, and a protective net is provided inside the water inlet.

[0015] By adopting the above technical solution, the water inlet is designed to facilitate the connection of water that needs to be filtered, ensuring water quality. The protective net is designed to isolate the fish fry in the water and prevent them from escaping.

[0016] In a preferred embodiment, an outlet is provided on the side of the filter structure body opposite to the inlet, and an internal connecting pipe is provided inside the filter structure body, with the outlet, the internal connecting pipe and the inlet being interconnected.

[0017] By adopting the above technical solution, the outlet is designed to facilitate the discharge of filtered water, thereby completing the water filtration operation and ensuring the normal operation of the structural components. The outlet, the inner connecting pipe, and the inlet are interconnected by the inner connecting pipe, so that the filtered water passes through the filter plate one and the filter plate two, ensuring the water filtration operation.

[0018] In a preferred embodiment, the main shell of the filter structure is composed of multiple layers of materials, and a stainless steel layer is disposed inside the main shell of the filter structure.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

A sealing gasket 15 is provided between the sealing plate 10 and the filter structure body 1. Multiple filter plates, including filter plate one 16 and filter plate two 17, are provided at the lower end of the sealing plate 10. During operation, the snap-fit ​​plates 7 and connecting bolts 8 facilitate the replacement of the sealing plate 10 by operators. This allows for adjustment and replacement of the filter plate size at the lower end of the sealing plate 10 according to different operational needs, thus meeting the water treatment requirements at different stages. The sealing gasket 15 strengthens the connection and seal between the sealing plate 10 and the filter structure body 1, ensuring the airtightness of the structural components and facilitating subsequent operations. The sealing plate 10 is fixed inside the handle 9, thus securing it within the filter tank of the filter structure body 1, ensuring the stability of the component. Multiple filter tanks and different filter plates 16 and 17 ensure efficient water filtration, facilitating subsequent operations. The design also allows for easy replacement, enabling quick switching between different pore sizes. The operator attaches the snap-fit ​​plate 7 on the side of the sealing plate 10 to the inside of the filter structure body 1, inserts the connecting bolt 8 into the snap-fit ​​plate 7, and then connects it to the threaded hole 14 inside the filter structure body 1, thus fixing the snap-fit ​​plate 7 in place and ensuring the stability of the sealing plate 10. For disassembly, the connecting bolt 8 is removed to release the seal plate 10, allowing for its removal and replacement. This structure can also be used to replace the filter plate with a larger pore size as the fish grows, based on actual water flow and circulation needs, enhancing water exchange. If disease is detected or temporary isolation is required, a sealing plate can be inserted to temporarily stop water exchange and facilitate disinfection.

The setting of the connecting plates 3 facilitates the connection between the outer frame plate 2 and the filter structure body 1, thereby ensuring the stability of the position of the outer frame plate 2 and facilitating subsequent position fixing operations of the filter structure body 1.

[0034] Reference Figure 1-2 The outer frame plate 2 has multiple rectangular plates 6 fixedly connected inside, and multiple fixing plates 4 fixedly connected to the side of the outer frame plate 2. The multiple rectangular plates 6 ensure the water permeability of the structure, which facilitates subsequent installation and fixing in the work area. The fixing plates 4 can be used to fix the outer frame plate 2 in the designated work area by using fixing screws.

[0035] Reference Figure 1-2 The filter structure body 1 has an inlet 11 on the side opposite to the connecting plate 3. A protective net 12 is installed inside the inlet 11. The inlet 11 facilitates the connection of water that needs to be filtered, ensuring the quality of the water.

[0039] The implementation principle of the device embodiment of this application that allows for changing the size of the permeable holes is as follows:

[0040] During equipment operation, the use of snap-fit ​​plate 7 and connecting bolts 8 facilitates easy replacement of the sealing plate 10 by operators. This allows for adjustment and replacement of the filter plate size at the lower end of the sealing plate 10 according to different operational needs, thus meeting the water treatment requirements at different stages. The sealing gasket 15 strengthens the connection and seal between the sealing plate 10 and the filter structure body 1, ensuring the airtightness of the structural components and facilitating subsequent operations. The connecting bolts 8, inserted into the handle 9, fix the sealing plate 10 within the filter tank of the filter structure body 1, ensuring component stability. Multiple filter tanks and different filter plates 16 and 17 ensure efficient water filtration, facilitating subsequent operations. The design also allows for easy replacement, enabling operators to perform tasks without... For quick replacement of filter plates with the same pore size, the operator snaps the snap-fit ​​plate 7 on the side of the sealing plate 10 into the interior of the filter structure body 1, inserts the connecting bolt 8 into the snap-fit ​​plate 7, and then connects it into the sealing gasket 15 inside the filter structure body 1, thereby fixing the position of the snap-fit ​​plate 7 and ensuring the stability of the sealing plate 10. When disassembly is required, the connecting bolt 8 is removed, thereby releasing the restriction on the sealing plate 10 and allowing it to be removed to complete the replacement operation. At the same time, this structure can be used to replace the filter plate with a larger pore size filter plate according to the actual water flow and circulation needs as the fish grow, enhancing the water exchange capacity. If disease is found or temporary isolation is required, a sealing plate can be inserted to temporarily stop water exchange and cooperate with disinfection treatment. By using this structure, it is easy to disassemble and replace different filter plates during the operation of the structure, thereby meeting different operational needs and ensuring the normal operation of the equipment components.
