[0002] In the process of penaeus vannamei aquaculture, the quality of water directly relates to the growth, health and yield of shrimps. Impurities and pollutants in the aquaculture water can affect the living environment of shrimps, cause diseases and reduce the aquaculture benefit. Therefore, it is crucial to filter and purify the aquaculture water.
[0003] Traditional penaeus vannamei aquaculture water filters have many problems in the filtering process. With the increase of filtering time, impurities will gradually accumulate on the filtering medium, resulting in a decline in filtering effect, and the filtering medium needs to be frequently replaced, which not only increases the aquaculture cost, but also consumes a lot of manpower and time. Moreover, when the filter is clogged, the water flow will be greatly reduced, affecting the normal circulation of the aquaculture water, and further adversely affecting the growth environment of shrimps.

[0035] like Figures 1-5 As shown, an automatic backwashing water filter for Litopenaeus vannamei aquaculture is illustrated in one embodiment of this disclosure, comprising:
[0036] The outer casing 1 and a pair of brackets 2 are fixed to the bottom of the outer casing 1;
[0037] Side cover 3 and connecting component 5, the side cover 3 is disposed on one side of the outer shell 1, and the connecting component 5 is disposed between the outer shell 1 and the side cover 3;
[0038] Filter flushing assembly 4 is disposed on the side cover 3 and the outer casing 1;
[0039] The filter flushing assembly 4 includes a drive motor 4-1, which is mounted on the side surface of the side cover 3. A pair of partitions 4-2 are provided inside the outer shell 1, one of which is connected to the output end of the drive motor 4-1. A filter layer 4-3 is connected between the partitions 4-2. Both ends of the filter layer 4-3 are provided with shields 4-4. A drain cover 4-5 is provided on one side of the outer shell 1. An inner groove 4-6 is opened on the inner surface of the outer shell 1. A pipe 4-7 is rotatably connected in the inner groove 4-6. Both ends of the pipe 4-7 are located outside the outer shell 1. Several flushing nozzles 4-8 are provided on the surface of the pipe 4-7. A second motor 4-9 is installed outside the outer shell 1. A drive wheel 4-10 is provided at the output end of the second motor 4-9 and at one end of the pipe 4-7. The drive wheel 4-10 is connected by a belt drive.
[0040] In some examples, a filter flushing assembly 4 is designed to achieve the effects of filtration and backwashing. This assembly includes a drive motor 4-1 mounted on the side surface of the side cover 3. A pair of partitions 4-2 are provided inside the housing 1, one of which is connected to the output end of the drive motor 4-1. When the drive motor 4-1 is running, it can drive the partition 4-2 to rotate. A filter layer 4-3 is connected between the partitions 4-2. The filter layer 4-3 is used to filter the fluid. It has shields 4-4 at both ends. A drain cover 4-5 is provided on one side of the housing 1 to discharge the filtered fluid. An inner groove 4-6 is opened on the inner surface of the housing 1. When the filter layer 4-3 rotates, the top water inlet can be covered by the shield 4-4, and the drain cover 4-5 and the inner groove 4-6 can be opened. During rinsing, the filtered material and rinsing water on the filter layer 4-3 can be discharged outward through the drain cover 4-5. The inner groove 4-6 is rotatably connected to the pipe 4-7, with both ends of the pipe 4-7 located outside the outer shell 1. Several rinsing nozzles 4-8 are provided on its surface for rinsing the filter layer 4-3. A second motor 4-9 is also installed outside the outer shell 1. The output end of the second motor 4-9 and one end of the pipe 4-7 are both equipped with a drive wheel 4-10, which is connected by a belt drive. When the drive motor 4-1 is working, the pipe 4-7 is rotated through the belt drive, and the rinsing nozzles 4-8 can repeatedly swing up and down to rinse the filter layer 4-3, resulting in a larger rinsing range and better effect, effectively maintaining the cleanliness of the filter layer 4-3.
[0041] like Figures 1-5 As shown, this embodiment proposes a connecting component 5 including a pair of elongated cavities 5-1, which are opened inside the outer shell 1 on both sides. One end of the elongated cavity 5-1 is provided with a round hole 5-2. A movable rod 5-3 is inserted into the elongated cavity 5-1 and the round hole 5-2. One end of the movable rod 5-3 is fixedly connected to the side cover 3, and the other end of the movable rod 5-3 is connected to a fixing nut 5-4 by threaded screwing.
[0042] In some examples, to achieve the effect of the filter layer 4-3 being able to be moved outward for easy maintenance, a connecting component 5 is designed. This component includes a pair of elongated cavities 5-1 opened on both sides of the outer shell 1. One end of each elongated cavity 5-1 has a round hole 5-2. A movable rod 5-3 is inserted into the elongated cavity 5-1 and the round hole 5-2. The movable rod 5-3 can move telescopically within the elongated cavity 5-1. One end of the movable rod 5-3 is fixedly connected to the side cover 3, making the side cover 3 and the movable rod 5-3 a whole. When the side cover 3 is pulled outward, it can be moved with the movable rod 5-3 as support. The other end of the movable rod 5-3 is connected to a fixing nut 5-4 by thread. By tightening or loosening the fixing nut 5-4, the movable rod 5-3 can be fixed, preventing the side cover 3 from being pulled out. This achieves the effect of connection, fixation and separation between the outer shell 1 and the side cover 3, facilitating the installation, disassembly and maintenance of the equipment.
[0043] For example, such as Figure 1 As shown, the drainage covers 4-5 are connected at an inclined angle.
[0044] In some examples, the tilt angle facilitates backwashing of filter layers 4-3, making it easier to remove contaminants.
[0045] For example, such as Figure 3 As shown, the position of the drainage cover 4-5 corresponds to the position of the inner tank 4-6.
[0046] In some examples, by using corresponding positions, the shields 4-4 at both ends of the filter layer 4-3 can simultaneously seal the drain cover 4-5 and the inner tank 4-6 without affecting normal filtration.
[0047] For example, such as Figure 3 As shown, the shield 4-4 has an arc-shaped transition structure and slides against the inner wall of the outer shell 1.
[0048] In some examples, the curved structure allows the shield 4-4 to move along the inner wall of the outer shell 1, maintaining a sealing effect.
[0049] For example, such as Figure 3 As shown, the water inlet and drainage of the outer casing 1 are located at the top and bottom, respectively.
[0050] In some examples, by being located at the top and bottom, it effectively complements the normal filtration and flushing process.
[0051] In actual use: Place the filter in a suitable position. The aquaculture water enters from the top of the outer shell 1, passes through the filter layer 4-3, and is discharged from the bottom. When backwashing is required, start the drive motor 4-1. The drive motor 4-1 drives the partition 4-2 connected to the output end to rotate, causing the filter layer 4-3 to rotate. The shield 4-4 covers the water inlet. Open the drain cover 4-5 and the inner tank 4-6. At the same time, start the second motor 4-9. The second motor 4-9 drives the pipe 4-7 to rotate through the transmission wheel 4-10 and belt. The flushing nozzle 4-8 flushes the filter layer 4-3. The flushed wastewater is discharged through the drain cover 4-5. If equipment maintenance is required, loosen the fixing nut 5-4, pull the side cover 3, and the movable rod 5-3 moves in the long cavity 5-1 to open the side cover 3. The filter layer 4-3 and other components can be inspected or replaced.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
