Description

Technical Field

[0001] The present invention belongs to the field of aquaculture, and particularly relates to a water circulation purification and oxygen supply device for aquaculture water. Background Art

[0002] At present, the aquaculture industry is growing day by day. While generating economic benefits, it also produces a large amount of wastewater. Most aquaculture manufacturers directly discharge the wastewater generated from aquaculture. The large amount of discharged water not only causes great waste but also pollutes the environment. Therefore, it is necessary to purify the aquaculture wastewater and then recycle it.

[0003] US20220312747A1 discloses a recirculating aquaculture system using a bioflocculant fermenter and aquatic organisms, which can stably manage the water quality of organic matter generated in a recirculating aquaculture system using bioflocculation technology, improve the productivity of aquaculture and hydroponic plants through nutrients generated by the decomposition of organic matter, and minimize the discharge of discharged water. WO8804524A1 discloses an aquaculture aeration and filtration system, a unique aeration and filtration system that can effectively supply a large amount of oxygen to the liquid to support aquatic organisms while removing waste in the aquarium. The pumping system can directly suck the liquid through the filter bed while sucking oxygen from the surrounding atmosphere to mix with the oxygen-deficient liquid or water. However, its application range still has great limitations. Summary of the Invention

[0004] The purpose of the present invention is to provide a water circulation purification and oxygen supply device for aquaculture water with an oxygen supply function, a water quality circulation purification function, which can increase the oxygen content in the water body, avoid water turbidity, control the suspension range of sediments, prevent sediments from depositing in the sewage discharge pool, make the sediments have good dispersibility, increase the filtration volume, reduce the filtration burden, concentrate the dirt, and facilitate sewage discharge.

[0005] The technical solution adopted by the present invention to achieve the above purpose is as follows:

[0006] An aquaculture pond with oxygen supply and water quality circulation purification functions, comprising: a breeding water pond and a sewage draining pond separated by a partition board, and an aeration component arranged in the breeding water pond, characterized in that: the aeration component includes an aeration base, a first aeration pipe is arranged around the aeration base, aeration holes are arranged on the side of the first aeration pipe, a second aeration pipe is connected above the aeration base, a marking float is arranged on the second aeration pipe, a third aeration pipe is connected above the marking float, and the third aeration pipe is connected to an air pump; a sliding component is sleeved outside the second aeration pipe, and the sliding component includes an inner ring and an outer ring, and the inner ring and the outer ring are connected by blade plates. The aeration component is fixedly arranged in the breeding water pond, and aeration of the breeding water pond is realized through the air pump to increase the oxygen content in the water body; through the arrangement of the first aeration pipe, the second aeration pipe and the third aeration pipe, aeration holes are arranged on the side of the first aeration pipe, and the circulation flow of the water body in the breeding pond can be realized during the aeration process; the marking float can make the second aeration pipe stable and vertical in the water, and mark the position range of the first aeration pipe and the aeration base in the water. During the aeration process, it can also drive the sediment at the bottom of the breeding water pond to move. Driven by the moving water body, the sediment can be discharged into the sewage draining pond through the partition board; by sleeving a sliding component outside the second aeration pipe, the sliding component can limit the upward moving speed of the air flow coming out of the bottom first aeration pipe, improve the dissolution of oxygen in the air flow in the water body, and increase the oxygen content in the water body. After the air flow hits the blade plates on the sliding component, the sliding component can rotate and push the water flow to the surrounding, which can reduce the upward movement of the suspended sediment at the bottom of the breeding pond and avoid the turbidity of the water body in the breeding water pond, and relatively control the resuspension range of the sediment; the outer ring of the sliding component can contact the partition board used to separate the breeding pond to ensure the arc structure of the partition board, which is helpful for the formation of the circulating water flow in the breeding pond. The blade plates can be inclined, and the shape of the blade plates can be set as a special shape, that is, the cross section of the blade plate is in the shape of a wedge, a trapezoid, a curve, etc. The blade plates can not only be straight, but also be streamline, curved, wavy, etc. A bearing can also be arranged in the inner ring of the sliding component, which fits outside the second aeration pipe to make it move on a plane.

[0007] Preferably, the partition board is provided with a diversion hole, and a diversion cover is arranged outside the diversion hole. The diversion holes are arranged on one side of the partition board in a concentrated manner. During use, the side with the diversion holes can be placed along the bottom of the pond. The diversion cover is arranged outside the diversion hole, which can make the sediment flow in a direction non-perpendicular to the partition board, so as to avoid accumulation at the diversion holes. When the water containing sediment passes through the diversion holes, the interaction makes the sediment disperse, and when the sewage discharge component discharges sewage and the water circulation device operates, it can further enhance the fluidity of the sewage flow passing through the diversion holes. And under the action of the aeration component, the sewage passing through the diversion holes will have higher fluidity, which is more conducive to the sewage in the breeding water pond flowing into the sewage draining pond and being discharged.

[0008] Preferably, the partition board and the pool wall of the aquaculture pond are connected by a flexible board. One side of the flexible board is fixed to the pool wall of the aquaculture pond through a first fastener, and the other side of the flexible board is connected to the partition board; the edge of the partition board is connected to the pool wall of the aquaculture pond through a second fastener. The partition board is an arc-shaped structure, and its two ends are hinged at the connection with the aquaculture pond. Then, a flexible board connection is also provided to control the bending degree of the partition board. The purpose is to avoid the unstable impact force of the water flow in the aquaculture pond on the partition board, resulting in deformation of the partition board during long-term use. By setting the hinge connection and the flexible board, a certain adjustment range for the deformation of the partition board can be achieved, which helps the partition board to return to its original state when the impact force is small.

[0009] Preferably, a sewage discharge component is arranged in the sewage discharge pool.

[0010] More preferably, the sewage discharge component includes a sewage discharge device. The sewage discharge device includes a sewage pump. The sewage pump is arranged on a floating board on the water surface. A floating body is arranged below the floating board. There is a sewage suction pipe passing through the floating board below the sewage pump. An extension rod is arranged outside the end of the sewage suction pipe, and a separation net is arranged below the extension rod.

[0011] Even more preferably, the extension rod and the separation net are connected by a rotating rod.

[0012] More preferably, the sewage discharge component includes a water circulation device. The water circulation device includes a water pump. The water pump is arranged on a floating board on the water surface. One side of the water pump is connected to a water suction pipe, and a filtering component is arranged at the end of the water suction pipe; the other side of the water pump is connected to a water outlet pipe, and the water outlet pipe leads to the aquaculture pond. The setting of the water pump is used to suck the water body below the filter screen. The water body is filtered through the filtering component, and part of the water body is pumped back into the aquaculture pond to avoid excessive use of water resources.

[0013] Even more preferably, the filtering component includes an auxiliary floating body. A flexible outer sleeve is arranged below the auxiliary floating body. The flexible outer sleeve is connected to a conical filter plate, and a hollow bottom plate is connected below the conical filter plate. During the suction process of the filtering component, it can drive components such as the auxiliary floating body to move up and down, which can play a role in shaking the filter screen and avoid clogging of the pores on the filter screen; due to the suction force of the water pump, it can cause the flexible outer sleeve to deform, and then the bottom plate and the conical filter plate also deform synchronously. In this way, the size of the openings on the bottom plate has a change range, and the relative shape of the bottom plate also changes. For the water body entering the flexible outer sleeve, the change in the shape of the bottom plate can play a guiding effect on the entering water body, increasing the filtration volume. And the shaking displacement of the auxiliary floating body in the water can change the suction direction at the bottom, avoiding always vertically sucking the water body at the bottom and reducing the filtration burden.

[0014] More preferably, the sewage discharge assembly further includes a filter screen. A filter screen is provided outside the sewage suction pipe. The diversion holes are provided on the partition plate below the filter screen, and no diversion holes are provided on the partition plate above the filter screen. The purpose is to ensure the water quality of the water body above the filter screen and concentrate the dirt below the filter screen for suction by the sewage discharge assembly. The size of the filter screen covers the entire sewage discharge pool.

[0015] Even more preferably, the filter screen is sleeved outside the sewage suction pipe; or, the filter screen is sleeved outside the water suction pipe; or, the filter screen is sleeved outside the water suction pipe and supported by the filter assembly at the end of the water suction pipe.

[0016] Since the present invention provides an aeration assembly and a sewage discharge assembly in the aquaculture pond, the aeration pipe is fixedly in contact with the pond bottom in the aeration assembly, the aeration holes are provided on the side of the bottom aeration pipe, the sliding assembly with vane plates is provided outside the vertical aeration pipe, the aeration assembly and the sewage discharge assembly are separated by the partition plate provided in the aquaculture pond, and the diversion holes with diversion covers are provided on the partition plate; the sewage discharge assembly includes a sewage discharge device, a water circulation device and a filter screen, so it has the following beneficial effects: it has an oxygen supply function and a water quality circulation purification function; it can increase the oxygen content in the water body, avoid water turbidity, control the suspension range of sediments, and prevent sediments from depositing in the sewage discharge pool; it can also make the sediments have good dispersibility, increase the filtration volume, reduce the filtration burden; and concentrate the dirt and facilitate sewage discharge. Therefore, the present invention is an aquaculture water circulation purification and oxygen supply device with an oxygen supply function, a water quality circulation purification function, increasing the oxygen content in the water body, avoiding water turbidity, controlling the suspension range of sediments, preventing sediments from depositing in the sewage discharge pool, making the sediments have good dispersibility, increasing the filtration volume, reducing the filtration burden, concentrating the dirt and facilitating sewage discharge.
