[0019] It also includes a controller; sensors are connected to the controller; the fan, inlet valve and drain valve are all controlled by the controller.

[0020] An all-weather tidal canvas aquaculture system includes an aquaculture tank and a vertical flow sand filter device;

[0021] The aquaculture tank is the aforementioned all-weather tidal canvas aquaculture tank;

[0022] The vertical flow sand filter device is an aquaculture wastewater treatment device based on vertical flow sand filter barrels, including an outer barrel, an inlet pipe, a central pipe, and multiple sand filter barrels; the inlet pipe, the central pipe, and the multiple sand filter barrels are all located in the outer barrel.

[0023] Inside; the sand filter barrel is equipped with sand filter bags;

[0024] The inner cavity of the outer tub is divided into an upper overflow area, a middle filtration area, and a bottom dirt collection area;

[0025] The central tube is coaxially arranged with the outer tub and is fixed inside the outer tub, located in the filtration zone; the water inlet pipe is composed of a horizontal section and a vertical section connected together; the outer end of the horizontal section of the water inlet pipe extends from the side wall of the outer tub as the water inlet end; the vertical section of the water inlet pipe is located inside the central tube and the water inlet pipe and the central tube are coaxial.

[0026] The bottom of the outer tub has a drain outlet;

[0027] Multiple sand filter barrels are supported by a frame and installed inside the outer barrel; the sand filter barrels are located in the filtration zone; the walls of the sand filter barrels are provided with water permeable holes; the bottom of the sand filter barrels is higher than the bottom of the central pipe;

[0028] The outer barrel is equipped with horizontally arranged baffles; multiple sand filter barrels are vertically inserted into the through holes on the baffles; the outer barrel is equipped with an overflow pipe on its wall; the overflow pipe is positioned below the top of the sand filter barrels and is located above the baffles.

[0029] The aquaculture tank is equipped with a stacked shrimp and crab farming device. The stacked shrimp and crab farming device includes a sleeve-type feeding mechanism and multiple farming units for raising shrimp and crabs;

[0030] The sleeve-type feeding mechanism consists of a sleeve and an inner tube fitted together.

[0031] The breeding unit is an open, square box-shaped container, with the sides and bottom of the breeding unit being mesh or grid surfaces;

[0032] Each breeding unit has a through hole on its bottom surface for inserting a sleeve;

[0033] Multiple aquaculture units are stacked on a casing;

[0034] The outer sleeve has multiple windows spaced evenly along its axial direction, and the inner tube has multiple feed troughs corresponding to these windows along its axial direction. Both the outer sleeve and the inner tube are vertically oriented. Under external force, the inner tube can rotate within the outer sleeve. When rotated until the window aligns with the feed trough, the feed trough is exposed within the rearing unit, allowing shrimp and crabs to access the feed and complete the feeding process.

[0035] It also includes a base, a cover plate, and vertical supports. The supports are used to support one side of multiple breeding units, increasing the stability of the breeding units.

[0036] Both the sleeve and the support rod are fixed to the base;

[0037] The cover plate is set on top of the support rod and above the breeding unit (to cover and press down the breeding unit to stabilize the entire device).

[0038] The support rod is equipped with pin holes and matching pins. After the cover plate presses down on multiple breeding units, it is then locked with the pins, making the entire device more stable.

[0041] A control method for an all-weather tidal canvas aquaculture tank is provided, which adopts an all-weather tidal canvas aquaculture tank and uses a tidal water level control method. The controller monitors the water level in the tank, and once the water level drops to h, the water filling valve is activated to replenish water until the water level reaches the preset height.

[0042] Beneficial effects:

[0043] The tidal canvas aquaculture tank of the present invention has the following technical advantages:

[0044] (1) It has heat preservation function and is suitable for all-weather breeding;

[0045] The color steel insulation board has an insulation layer, and the bottom of the canvas breeding box is equipped with an insulation film. In winter, it can be heated by ground source heat pumps and heaters, and in summer, it can be cooled by adding groundwater. This effectively ensures a constant water temperature, saves energy, and ensures that fish can grow rapidly at the most suitable water temperature all year round.

[0046] (2) The sludge collection mechanism based on the inclined groove plate is adopted, and the sludge collection effect is good.

[0047] The inclined trough strainer plate functions similarly to an inclined tube sedimentation tank. Once residue enters the collection area, it is not easily stirred up. Moreover, the aeration pipe is located above the inclined trough strainer plate, which can also effectively prevent impurities from being stirred up. Thus, the adoption of this new mechanism can effectively improve the collection effect.

[0048] (3) The system adopts tidal drainage and water replenishment, which is highly automated, increases the water exchange volume, realizes timely sewage discharge, keeps the water in the breeding tank clean, and promotes the rapid growth of fish.

[0049] (4) Adopting a partitioned breeding method, which separates the breeding of multiple varieties by using partition boards, can also carry out comparative experiments on the breeding of the same or multiple varieties.

[0050] (5) It has a simple structure, low cost, and is easy to promote and implement.

[0051] These aquaculture boxes are easy to transport, install, and disassemble. They have excellent heat preservation and waste collection capabilities, and can be divided into different aquaculture areas. Through tidal automatic water inlet and outlet, they can increase water exchange and effectively remove uneaten feed and feces, enabling separable, all-weather, high-density aquaculture.

[0052] In summary, this all-weather tidal canvas aquaculture tank is feature-rich, easy to promote and implement, suitable for high-density aquaculture, and has significant economic benefits.

[0053] Furthermore, this aquaculture system integrates a wastewater treatment device based on a sand filter, which facilitates recirculating aquaculture or ensures that wastewater meets discharge standards. Due to its low cost, this type of aquaculture tank allows for high-density cultivation of high-value aquatic species such as shrimp and crabs, generating more significant economic benefits.

[0100] A wastewater treatment method employs the aforementioned wastewater treatment device based on a vertical flow sand filter.

[0101] The processing procedure is as follows:

[0102] Wastewater enters the central pipe through the inlet pipe and then enters the filtration zone, where it is filtered by sand filters. The clear liquid is discharged through the overflow pipe, while impurities settle in the collection zone.

[0103] like Figure 9 Detailed steps explained:

[0104] S1: Wastewater enters the main tank through the inlet of the inlet pipe;

[0105] S2: Sewage flows upward through the vertical section of the inlet pipe;

Rotate the inner tube until the window is aligned with the feed trough, exposing the feed trough within the rearing unit, making it easy for shrimp and crabs to access the feed. To feed again, remove the inner tube and repeat the above steps.

[0126] Specifically, the support rod is equipped with pin holes and matching pins 7. After the cover plate presses down on multiple breeding units, it is then locked with the pins, making the entire device more stable.

[0127] The sleeve-type feeding mechanism and the breeding unit are in two sets, and are arranged symmetrically with respect to the support rods. This ensures good balance and saves space, thereby improving the productivity per unit space.

[0128] like Figure 5 The inner tube has multiple inner tube openings 62 at equal intervals along the axial direction of the inner tube, and multiple partitions 63 at equal intervals along the axial direction of the inner tube. Each inner tube opening and partition forms a feed trough.

[0132] The method of using a combination of outer and inner tubes for baiting ensures precise baiting and high bait utilization.

[0133] (3) Layered combined breeding saves space, has a high breeding density, and has considerable economic benefits.

[0134] (4) With the casing as the axis, each breeding unit can be rotated or lifted to open, which facilitates the release and collection of crabs, reduces labor intensity, can be operated by a single person, and is suitable for different scales of breeding.

[0135] In summary, this single-room stacked shrimp and crab farming device adopts a completely new structure and concept, with precise and convenient feeding, simple operation, and can achieve high density and high survival rate in shrimp and crab farming, resulting in good economic benefits and making it suitable for widespread implementation.
