Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Mariculture is a production activity that utilizes coastal shallow seashores to cultivate marine aquatic economic plants and animals, including shallow sea aquaculture, beach aquaculture, harbor aquaculture, etc. In the technical field of mariculture, for mariculture that is separated from the ocean, such as indoor viewing and live product transportation, it is necessary to filter the aquaculture seawater.

In the related art, aquaculture seawater is usually filtered by adsorption filtration, adsorption filtration or biochemical filtration. However, in actual use, the inventor found that the traditional filtration method uses many device parts, which makes the filtration device larger in size and weight, and is not suitable for indoor viewing occasions, and is not convenient to use during transportation.

In view of this, the embodiment of the present application provides a modular filter barrel for seawater aquaculture. In the modular filter barrel for seawater aquaculture provided in the embodiment of the present application, the barrel body is used as a filtering container for aquaculture seawater, and a cover plate, a diverter cover, an adsorption filter layer, a biochemical filter layer and a screen are sequentially installed in the barrel body from top to bottom. The above structural design can enable the aquaculture seawater to achieve a filtering function through the filter module installed inside the barrel body. In addition, the entire design is small in size and light in weight. While ensuring that the filtering function can be achieved, it can also be used in viewing occasions and during transportation, so it has extremely strong practicality.

As shown in Figures 1 to 12, the modular filter barrel for seawater aquaculture provided in the embodiment of the present application includes a barrel body, a cover plate, a diversion cover, an adsorption filter layer, a biochemical filter layer and a screen, wherein the barrel body is a container for filtering the aquaculture seawater to be treated, and an opening is provided at the top of the barrel body, and a water outlet connected to the outside is also provided on the barrel body. In this embodiment, the material of the barrel body can be PE plastic. The actual size of the barrel body can be selected and designed according to the usage scenario.

A cover plate is provided at the top opening of the barrel body, and the cover plate mainly serves to close the opening. A water inlet may be provided on the cover plate, and the water inlet is connected to the inside of the barrel body, and the water inlet is used in conjunction with the water outlet to achieve the function of filtering and treating the aquaculture seawater through the filter barrel. In actual use, the aquaculture seawater to be treated can be poured into the barrel body through the water inlet on the cover plate to facilitate subsequent filtering treatment.

As shown in Figure 1, the barrel body is sequentially installed with a diverter hood, an adsorption filter layer, a biochemical filter layer and a screen from top to bottom. Among them, the diverter hood is provided with filter cotton inside, and the diverter hood mainly plays the role of mechanical filtration. The diverter hood can preliminarily remove impurities such as suspended matter and solid particles mixed in the aquaculture seawater. The adsorption filter layer is arranged below the diverter hood, and the adsorption filter layer includes activated carbon, and the adsorption filter layer can adsorb heavy metals and other harmful substances in the aquaculture seawater.

The biochemical filtration layer is located below the adsorption filtration layer. The biochemical filtration layer includes one or more biochemical filter materials. In this embodiment, shellfish can be used as the biochemical filter material for the biochemical filtration. For example, scallops cultured in seawater can be selected as the biochemical filter material, and shellfish from other sources can also be selected as the biochemical filter material. In actual use, the selected shellfish can be simply crushed into fragments of about 3cm to 6cm, and then washed and soaked in seawater and used directly as the biochemical filter material. The biochemical filter material using shellfish as the biochemical filter layer has the advantages of low carbon, environmental protection and low price. In addition, the biochemical filter material is suitable for the reproduction and survival of aerobic nitrifying bacteria and can be used as a high-efficiency seawater nitrification filter material.

The filter is arranged at the bottom of the barrel body, and the filter can be a plastic hot-melt mesh. The filter is connected to the water outlet of the barrel body, which can ensure that the aquaculture seawater can be discharged smoothly after multiple filtration treatments. In addition, the filter can also be used to precipitate the residue in the biochemical filter material. Since there is a part of the residue on the filter, the flow rate of the aquaculture seawater at the filter is relatively low, which allows a certain number of anaerobic bacteria to survive in this part of the space. When the filter barrel is used during transportation, the residue of the biochemical filter material will produce nitrification reaction in mutual collision, so that the aquaculture seawater can be efficiently biochemically filtered.

In the modular filter barrel for seawater aquaculture provided in the embodiment of the present application, the barrel body is used as a filtering container for aquaculture seawater, and a cover plate, a diverter cover, an adsorption filter layer, a biochemical filter layer and a screen are sequentially installed in the barrel body from top to bottom. The above structural design can enable the aquaculture seawater to achieve the filtering function through the filter module installed inside the barrel body. In addition, the entire design is small in size and light in weight. While ensuring the filtering function, it can also be used in viewing occasions and during transportation, so it has strong practicality.

In some embodiments, the cover plate includes a side plate, a plurality of diverter plates arranged in a direction, and a plurality of baffle plates. As shown in FIG6 , the shape formed by the side plate is consistent with the shape of the opening at the top of the barrel body, and the inner wall of the side plate is provided with a plurality of diverter plates arranged in a direction, and a ventilated gap is provided between adjacent diverter plates. The inner wall of the side plate is also provided with a plurality of baffle plates, which are located above the ventilated gap, and a water inlet gap is formed between the baffle plate and the diverter plate below.

As shown in Figure 6, the air-permeable gaps between adjacent diverter plates allow external air to flow into the interior of the barrel, and the baffle is located above the air-permeable gap to prevent the aquaculture seawater from splashing outwards during the process of entering the barrel. In some possible implementations, the cross-sectional shape of the diverter plate can be triangular, and the tip of the diverter plate faces the top of the barrel. By adopting the diverter plate with this structural design, the flow rate of the aquaculture seawater entering the barrel can be increased, and the aquaculture seawater can be prevented from remaining on the diverter plate.

In some embodiments, a flow control cap may be further provided on the cover plate, as shown in FIG. 10 and FIG. 11 , the flow control cap is designed to be larger at the top and smaller at the bottom, that is, the outer diameter of the top opening is larger than the outer diameter of the bottom opening, and the flow control cap is designed to be a stepped structure from the top to the bottom. In addition, the top of the flow control cap is provided with a plurality of flow control holes, which are connected to the interior of the barrel body through the cover plate. In actual use, the flow control cap can be used as the water inlet of the barrel body, thereby realizing the function of adjusting the flow rate of the incoming water.

In some embodiments, the diverter cover is provided with water-conducting grooves and air holes, as shown in Figures 8 and 9, the diverter cover can be designed as a quadrangular pyramid structure, and a plurality of water-conducting grooves are provided on the four sides of the diverter cover, and air holes are evenly distributed inside each water-conducting groove. Under the action of the plurality of water-conducting grooves and the plurality of air holes, the diverter cover can evenly spread the aquaculture seawater with air into various places in the barrel.

In some embodiments, the filter screen can be a three-dimensional mesh, as shown in FIG3 , a nine-square grid is provided at the bottom of the barrel body, and a filter screen is installed in each grid in the nine-square grid. The barrel body is composed of an outer shell and an inner shell, and a cavity is provided between the outer shell and the inner shell. The upper end of the filter screen is in contact with the biochemical filtration layer, the lower end of the filter screen is in contact with the cavity, and the cavity is also connected to the water outlet of the barrel body, and the water outlet is located at the top of the barrel body. In a specific implementation, the water outlet can be connected to an external water pump to achieve filtering and collection of aquaculture seawater.

In some embodiments, as shown in FIG. 2 , FIG. 4 and FIG. 5 , the outside of the barrel body may be provided with a groove and a protrusion, the inside of the protrusion is provided with a water guide cavity, the water guide cavity is connected with the cavity, and a water outlet is provided at the end of the water guide cavity, and the water outlet is located at the bottom of the barrel body. In this embodiment, the water outlet can be used as an overflow outlet, and the aquaculture seawater can be discharged outward through the overflow outlet after being filtered. When the aquaculture seawater is in the filtering process, the water outlet can be blocked with a sealing cap; when the aquaculture seawater needs to be discharged outward, the water outlet can be connected with the outlet pipe so that the aquaculture seawater after filtering can be discharged to a designated location in a direction.

In some embodiments, the filter barrels can be used alone or in combination. As shown in FIG. 2 and FIG. 12 , the outside of the barrel body is provided with grooves and protrusions, and the barrel body can be designed as a rectangular parallelepiped structure, wherein the grooves and protrusions are distributed on adjacent sides of the barrel body. In actual use, the filter barrels can be arranged and combined as shown in FIG. 12 , so as to adapt to different filtering scenarios and filtering intensity requirements.
