Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a filtration and sterilization device for the industrialized farming of the spotted snail. Background Technology

[0002] The spotted whelk, also known as the flower whelk, belongs to the phylum Mollusca, class Gastropoda, order Mesogastropoda, family Molybdidae, and genus *Bellamya*. It is an edible snail widely distributed along the coast of my country. This species is highly prized for its delicious, sweet, and nutritious meat, making it a favorite among seafood lovers and an important economic shellfish in the southern coastal regions of my country.

[0003] The cultivation of spotted swamp snails requires extremely high water quality. The quality of the aquatic environment affects the quality of the bottom sediment, and directly impacts the growth, reproduction, and health of the snails. In actual cultivation, water filtration and sterilization are crucial for ensuring a stable cultivation environment and preventing the spread of disease.

[0004] Currently, the cultivation of *Bracharina buergeriana* (a type of whelk) commonly employs a factory-style cultivation model where a sand layer is laid in the cultivation pond. In this model, the water in the pond not only provides the whelks with necessary dissolved oxygen but also removes impurities from the bottom sand brought up by aeration. To effectively stabilize water quality and remove impurities promptly, farmers often have to frequently change the water. This practice not only leads to a significant waste of water resources, increased cultivation costs, and a heavier workload for maintenance workers, but also causes unnecessary damage to the ecological environment. Therefore, how to reduce the use of fresh seawater, lower cultivation and maintenance costs, and reduce the environmental impact of wastewater while ensuring water quality and efficient wastewater removal has become an urgent problem to be solved in the *Bracharina buergeriana* cultivation industry. Therefore, this utility model proposes a filtration and sterilization device for the factory-style cultivation of *Bracharina buergeriana*. Utility Model Content

Both the upper and lower ends of the water level observation pipe 9 are connected to the inside of the filter box 1, and a water level float ball 10 is provided inside the water level observation pipe 9.

[0038] The top of the filter box 1 is provided with a top cover plate 2. Welding strips 21 are fixed to the front and rear ends of the top cover plate 2, and the side of the welding strips 21 is provided with a top cover plate fixing hole 22. Two multi-functional flushing device fixing holes 23 are provided in the middle of the top cover plate 2, and two multi-functional flushing devices 6 are installed through the multi-functional flushing device fixing holes 23. An adjustable fan-shaped nozzle 7 is provided at the bottom and middle of the water pipe below the multi-functional flushing device 6. A fully submersible ultraviolet lamp 15 is fixed above the adjustable fan-shaped nozzle 7 by cross cable ties. The multi-functional flushing device 6 is connected to the intelligent water pump through a water pipe.

[0039] In the middle of the front side of the filter box 1 in the water purification area, a first water outlet 13 and a second water outlet 14 are provided from bottom to top.

[0040] Furthermore, the filter plate 3 is provided with water permeable holes 32 evenly distributed on the filter plate 3, and the filter plate 3 is provided with first plate perimeter fixing holes 31 at the edge of the filter plate 3, and multiple first intermediate fixing holes 33 are provided in the middle of the filter plate 3.

[0041] The filter plate 3 has a first welding position 34 on the left side and a second welding position 35 on the right side. The first welding position 34 and the second welding position 35 of the filter plate 3 are welded and fixed to the inner wall of the filter box 1, respectively.

[0042] The filter plate 4 has water-permeable holes 42 evenly distributed on it. The filter plate 4 has a second plate perimeter fixing hole 41 at its edge and a number of second intermediate fixing holes 43 in its middle.

[0043] The fixing holes 31 around the first plate correspond to the fixing holes 41 around the second plate and are connected by screws. The fixing holes 33 in the first middle plate correspond to the fixing holes 43 in the second middle plate and are connected by screws.

[0044] The thickness of the filter plate 3 is the same as that of the filter box 1. Multiple rows of 20-90mm filter plate permeable holes 32 are evenly arranged on the filter plate 3, and the spacing between the permeable holes is 10-35mm. Multiple first plate perimeter fixing holes 31 are evenly arranged around the permeable holes 32 of the filter plate, and first middle fixing holes 33 are evenly distributed in the middle of the plate.

[0045] The thickness of the filter plate 4 does not exceed 10mm. Multiple rows of 20-90mm filter plate permeable holes 42 are evenly arranged on the filter plate 4. When the filter plate 4 is pressed on the filter plate 3, the permeable holes of the filter plate 4 overlap with the permeable holes of the filter plate 3. The width of the filter plate 4 is narrower than the width of the filter plate 3 by the same width on both sides (5-25mm). The top and bottom ends of the filter plate 4 are 5-20mm longer than the permeable holes at the top and bottom ends. The top end of the filter plate 4 is flush with the top end of the filter plate 3. Multiple second plate perimeter fixing holes 41 are evenly arranged around the permeable holes of the filter plate, and second intermediate fixing holes 43 are evenly distributed in the middle of the plate. The fixing holes of the filter plate should overlap with the fixing holes of the filter plate.

[0046] Furthermore, the filter housing 1, filter plate 3, filter pressure plate 4, and top cover 2 are all made of lightweight, corrosion-resistant, and UV-resistant PP material. The thickness of the filter housing 1 is 8-15mm.

[0047] Furthermore, the height of the filter plate stilling plate 5 does not exceed 30cm, and in this embodiment, the height is 15cm. The filter plate stilling plate 5 is a solid plate, and water cannot flow at the filter plate stilling plate 5. Mucus and attached substances that settle down under gravity, as well as large particles of dirt, will be deposited here.

[0048] The lower end of the water level observation pipe 9 is at the same height as the first sewage outlet 11 and the second sewage outlet 12, and the upper end is higher than the second water outlet 14. A water level float ball 10 is installed in the water level observation pipe 9. At the same time, water level controllers are installed at both ends of the water level observation pipe to automatically control the bottom suction water pump 8 at the water inlet.

[0049] In this embodiment, the filter housing 1 is 1000mm long, 500mm wide, and 600mm high, with a thickness of 10mm. A filter plate 3 is inclinedly installed at 260mm from the left side of the bottom plate and 750mm from the left side of the top plate. The filter plate's still water plate 5 is 15cm high. The edges of the filter plate 3 in contact with the filter housing 1 are fixed by hot-melt welding, which also prevents the housing from deforming and bulging outwards as the water volume increases. A filter screen with a mesh size greater than 100 is covered on the filter plate 3, and a filter pressure plate 4 is then placed on top of the filter screen. The filter plate 3, filter screen, and filter pressure plate 4 are all secured with screws. The filter plate 3 divides the interior of the filter housing 1 into a wastewater zone on the right and a clean water zone on the left.

[0050] During daily use, when the fully submersible UV lamp 15 is turned on, a waterproof and opaque tarpaulin should be used to cover the top of the filter box 1 to reduce the harm of the UV lamp to the aquaculture personnel. The water level observation tube 9 is set on the outside of the filter box 1, which allows maintenance personnel to observe the water level more intuitively when patrolling the aquaculture area. A water level controller is set in the sewage area of ​​the filter box 1.

[0051] In the water purification area of ​​the filter box 1, two multi-functional flushing devices 6 are evenly arranged, and the bottom of the water pipe below the multi-functional flushing device 6 is located 20cm above the bottom of the box. An adjustable fan-shaped nozzle 7 is installed at the bottom and middle of the two water pipes respectively. A fully submersible ultraviolet lamp 15 is fixed above the adjustable fan-shaped nozzle 7 by cross-shaped cable ties. The multi-functional flushing device 6 is connected to the intelligent water pump through a water pipe. A second drain outlet 12 is set at the bottom of the front middle position of the filter box 1 in the water purification area. A first water outlet 13 is set at the front middle position of the filter box 1 in the water purification area, 30cm from the bottom, and a second water outlet 14 is set at the bottom 50cm from the bottom.

[0052] The working principle of this utility model is as follows:

[0053] like Figure 1 As shown in the diagram, during daily use, the filter box 1 is installed on one side of the breeding pond, with its lower edge mounted on a fixed frame above the pond's edge. The top of the filter box 1 is covered with a waterproof, opaque tarpaulin. A high-flow-rate bottom-suction pump 8 within the filter box 1 draws water from the pond's drainage pipe. The start-up time can be remotely set via mobile phone or computer, automatically activating the bottom-suction pump 8 and the fully submersible UV lamp 15 after a certain delay from the usual feeding time. This effectively removes uneaten feed, mucus, and excrement from the *Bambusa multiplex* breeding pond, reducing most of the pollution sources in the pond's bottom sediment. After the water is drawn into the filter box 1, it undergoes a period of water storage. During this time, the mucus and attached substances, along with large particles of dirt, gradually settle due to gravity. Once the water level exceeds the height of the filter plate's still water plate 5, the water is filtered through a filter screen fixed between the filter plate's perforations 32 and the filter pressure plate's perforations 42. The filtered water then flows into the left-side clean water area.

[0054] The method of fixing the filter screen using a filter plate 3 and a filter pressure plate 4 is more effective than fixing it with pressure strips, as it can withstand greater flow pressure and provides a better fixation. This prevents localized contaminants from escaping into the clean water area and avoids damage to the filter screen due to insufficient pressure under high flow rates. When water enters the clean water area, the fully submersible UV lamp 15 performs large-scale sterilization. After the water level in the clean water area reaches the outlet height, the clean water undergoes sterilization by the fully submersible UV lamp 15 for a certain period of time before flowing into the clean water inlet pipe of the aquaculture pond area.

[0055] When the filtration time reaches 2.5 hours, or when the water level controller reaches the upper water level, the bottom suction water pump 8 will automatically shut off and the drain electric valve will automatically open. When the water level drops to the lower water level controller, the intelligent water pump of the multi-functional flushing device 6 will automatically turn on to clean the filter screen. After 2 minutes of self-cleaning, the intelligent water pump of the multi-functional flushing device 6 will automatically shut off, then the drain electric valve will automatically close, and the bottom suction water pump 8 will automatically turn on again to start filtering the aquaculture water.

[0056] When the Dongfeng snail pond needs oxygen replenishment, the adjustable fan-shaped nozzle 7 connected to the lower end of the multi-functional flushing device 6 via the threaded port can be replaced with an aeration head, and the intelligent water pump at the upper end can be replaced with an air pump. This can achieve water filtration, ultraviolet sterilization, and oxygen replenishment at the same time, thereby increasing the dissolved oxygen content in the snail pond.
