Description

Technical Field

[0001] This utility model relates to an integrated water storage tank. Background Technology

[0002] The adoption of facility-based aquaculture has become a current trend because it does not rely on natural ponds, is easy to promote and implement, and can support high-density farming. Existing common aquaculture equipment is generally based on cylindrical containers (canvas containers, galvanized steel containers, and PP containers, etc.), and equipped with dedicated water treatment devices (nitrification devices and disinfection devices, etc.), occupying a large area. For example, Chinese Patent Publication No. CN207639476U discloses a recirculating aquaculture system, including a culture tank and a water conditioning tank. The culture tank has at least one culture water chamber for aquaculture. The water conditioning tank has a filter device, a sterilizer, a protein separator, a biofilter tower, and the water conditioning chamber connected in sequence by pipes. A water quality monitoring device is installed in the water conditioning chamber. The culture water chamber is connected to the inlet of the filter device through an outlet pipe and to the water conditioning chamber through a return pipe. It also includes a first water pump that drives the water in the culture water chamber through the filter device, sterilizer, protein separator, and biofilter tower into the water conditioning chamber, and a second water pump that drives the water in the water conditioning chamber back to the culture water chamber through the return pipe. This utility model of a recirculating aquaculture system has a high degree of integration and features high efficiency, energy saving, low cost, and wide regional adaptability. Although the device is feature-rich and involves many components, it is not highly integrated and occupies a large area, making it more suitable for large-scale aquaculture.

[0003] In addition, some current devices focus on miniaturization and integration, but their functionality still needs further improvement. For example, Chinese patent CN105594650 A discloses a high-efficiency recirculating aquaculture tank for aquaponics, which uses a conical bottom for waste collection and discharge, but this device has limited functionality. Chinese patent CN219894312U discloses a fully automatic ecological recirculating aquaculture tank, including a tank body with an aeration device and a water transfer device inside. The aeration device includes an aeration pipe and an aeration air pipe, with an air outlet on the aeration pipe. The water transfer device includes a water transfer air pipe and a water transfer plate, with the bottom of the water transfer plate connected to the water transfer aeration pipe. The water transfer plate is angled to the bottom of the tank body and arranged along the axial direction of the tank body. It also includes a sludge removal device. Although this device integrates an aeration device, it lacks a disinfection function.

[0004] Therefore, it is necessary to design a new integrated water storage device for aquaculture that can significantly improve water quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an integrated water storage tank with a compact structure and rich functions.

[0006] The technical solution of the utility model is as follows:

[0007] An integrated water storage tank, the tank body is divided into 3 areas by a first partition and a second partition: a nitrification zone, a water storage zone and a disinfection zone, with the water storage zone located between the nitrification zone and the disinfection zone;

[0008] The bottom of the first partition is provided with a first water inlet for connecting the bottom of the nitrification zone and the bottom of the water storage zone;

[0009] The bottom of the second partition is provided with a second water inlet for connecting the bottom of the water storage area and the bottom of the disinfection area;

[0010] The bottom of the water storage area is equipped with a first conical bottom; the bottommost end of the first conical bottom is connected to the bottom drainage pipe;

[0011] The nitrification zone is equipped with a grid plate and multiple nitrification balls installed on the grid plate; the bottom of the nitrification zone is a second cone bottom; the bottom of the second cone bottom is connected to a drain pipe with a drain valve; the nitrification zone is equipped with an aeration disc and an aeration pipe connected to the aeration disc;

[0012] The bottom of the disinfection zone is equipped with a ceramic disc for aeration connected to an ozone pipe; a submersible pump is also installed in the disinfection zone; the submersible pump and the water pumping pipe connected to the submersible pump are used to pump the water in the disinfection zone into the external aquaculture pond.

[0013] Both the first and second conical bottoms are used for collecting sludge. The bottom drain pipe is equipped with a bottom drain valve, which is not shown in the figure.

[0014] Ultraviolet tubes are also installed in the disinfection area.

[0015] The third partition within the disinfection zone divides it into two independent areas: an ozone disinfection zone and a water pumping zone. A water channel is installed within the disinfection zone, with one end connecting to the second water inlet and the other end connecting to the bottom of the zone. Water disinfected by ozone flows through the wall (i.e., over the third partition) into the water pumping zone.

[0016] Ultraviolet (UV) tubes are also installed in the pumping area. The UV tubes are fixed to the side of the pumping area.

[0017] The grating is made up of two grating panels joined together at an angle, which can be 45-60 degrees, thereby increasing the permeable area.

[0018] A spray pipe is fixed at the top of the nitration zone.

[0019] The proper application of ozone technology can improve the aquaculture environment, increase farming efficiency, and enhance the health of aquatic organisms. However, high concentrations of residual ozone are toxic to fish, shrimp, and other aquatic life, affecting their survival. Therefore, ozone disinfection is not always necessary. It is generally activated during the initial water intake to thoroughly disinfect the entire water circulation system. After disinfection, allowing the water to stand or be aerated for 2-3 hours before introducing fish and shrimp can prevent any adverse effects. Beneficial effects

[0020] This utility model discloses an integrated water storage tank that integrates a nitrification module and a disinfection module (ozone disinfection and ultraviolet disinfection), and also includes a water storage tank within the storage zone. The nitrification zone is further enhanced with packing materials (nitrification balls, porous balls, etc.) and an aeration device to achieve further biochemical treatment of the water, thereby improving water quality. Both the nitrification zone and the storage zone are equipped with conical bottoms for easy collection and discharge of wastewater.

[0021] This device effectively extends the nitrification time of circulating water and can effectively reduce ammonia nitrogen and nitrite in aquaculture water. The ozone disinfection zone adopts a negative pressure design, that is, the top is closed, which can improve the ozone utilization rate and disinfection effect, and the decomposed oxygen can also be fully dissolved into the aquaculture water.

[0022] In summary, the integrated water storage tank of this utility model has a high degree of integration and rich functions, making it suitable for widespread implementation. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example

[0027] like Figure 1An integrated water storage tank, the tank body is divided into 3 areas by a first partition 22 and a second partition 23: a nitrification zone 7, a water storage zone 8 and a disinfection zone 12, the water storage zone being located between the nitrification zone and the disinfection zone;

[0028] The bottom of the first partition is provided with a first water inlet 19 for connecting the bottom of the nitrification zone and the bottom of the water storage zone;

[0029] The bottom of the second partition is provided with a second water inlet 10 for connecting the bottom of the water storage area and the bottom of the disinfection area;

[0030] The bottom of the water storage area is provided with a first conical bottom (18); the bottom end of the first conical bottom is connected to the bottom drain pipe 17;

[0031] The nitrification zone is equipped with a grid plate 3 and multiple nitrifying balls 4 mounted on the grid plate. The bottom of the nitrification zone is a second cone bottom 20. The bottom of the second cone bottom is connected to a drain pipe 1 with a drain valve 2. The nitrifying balls are generally higher than the liquid level to achieve better filtration. Nitrifying balls can be replaced with packing materials such as K3. Multiple nitrifying balls are placed in the water body above the grid plate. An aeration disc 25 and an aeration pipe 26 connected to the aeration disc are located in the area between the grid plate and the second cone bottom. The aeration pipe and aeration disc can also be placed above the grid plate. The nitrifying balls provide a carrier for nitrifying bacteria, while the aeration pipe and aeration disc provide sufficient oxygen. During the reproduction of nitrifying bacteria, ammonia nitrogen, COD, and nitrite levels in the water body can be significantly reduced.

[0032] The bottom of the disinfection zone is equipped with a ceramic disc 15 for aeration connected to an ozone pipe; a submersible pump 14 is also installed in the disinfection zone; the submersible pump and the water pumping pipe connected to the submersible pump are used to pump water from the disinfection zone into an external aquaculture pond. A spray pipe 5 is fixed at the top of the nitrification zone.

[0033] Both the first and second conical bottoms are used for collecting sludge. The bottom drain pipe is equipped with a bottom drain valve, which is not shown in the figure.

[0034] The third partition 24 within the disinfection zone divides the zone into two independent areas: an ozone disinfection zone and a water pumping zone. A water guiding channel 21 is installed within the disinfection zone, with one end connecting to the second water inlet and the other end connecting to the bottom of the disinfection zone. Water disinfected by ozone enters the water pumping zone by passing over the wall (i.e., over the third partition).

[0035] An ultraviolet tube 16 is also installed in the pumping area. The ultraviolet tube is fixed on the side of the pumping area.

[0036] The grating can be an inclined plate (or a flat plate, i.e., a horizontally placed plate).

[0037] The proper application of ozone technology can improve the aquaculture environment, increase farming efficiency, and enhance the health of aquatic organisms. However, high concentrations of residual ozone are toxic to fish, shrimp, and other aquatic life, affecting their survival. Therefore, ozone disinfection is not always necessary. It is generally activated during the initial water intake to thoroughly disinfect the entire water circulation system. After disinfection, allowing the water to stand or be aerated for 2-3 hours before introducing fish and shrimp can prevent any adverse effects.

[0038] Description of the working process of this device:

[0039] First, water is injected into the nitrification zone through the water source, inlet pipe, and spray pipe. After nitrification treatment, the water in the nitrification zone enters the storage area through the first permeable inlet 19, and then enters the ozone disinfection zone in the disinfection area through the second permeable inlet 10 and the water guiding channel. After the ozone disinfection zone has water, the ozone generator is turned on to aerate the ceramic disc. The water in the ozone disinfection zone flows over the wall and enters the pumping area. After the pumping area has water, the submersible pump and ultraviolet tube are turned on to thoroughly disinfect the water.

[0040] Then turn off the ozone generator and let it stand for 2 hours before pumping the water from the disinfection area to an external aquaculture pond or tank for aquaculture.

[0041] During the use of this equipment, the ozone generator can be turned off while all other equipment is turned on, in which case the ultraviolet tube is responsible for disinfection of the water.

[0042] If there are contaminants (such as uneaten bait) at the bottom of the nitrification zone during the use of this equipment, the drain valve can be opened to discharge the contaminants. The bottom drain valve in the water storage zone can also be opened to discharge the contaminants as needed.

[0043] If this device is used as a water storage tank, the ozone generator can be kept on continuously, as long as it is turned off 2-3 hours before using the water in the device.

[0044] The first permeable inlet has 19 mesh grids to prevent nitrification balls from entering the water storage area.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
