Description

Cage type multi-stage self-purification circulating water fish pond

technical field

The utility model relates to a cage type multi-stage self-purifying circulating water fish pond in the technical field of aquaculture.

Background technique

At present, many indoor circulating water fish ponds are built. The general structure is rectangular or oval, and the size depends on the scale of breeding. Most of these fish ponds use reinforced concrete or brick fish ponds. The cement pool is equipped with inlet and outlet facilities, and the ports in the pool are equipped with plastic nets or barbed wire to prevent escape. The water flow in the fish pond is required to be uniform and circulated to the corners. In order to increase the dissolved oxygen in the water body, several air pumps are generally turned on for oxygenation. However, this kind of indoor circulating water culture pond usually has many dead corners in the pond and is easy to accumulate pollution, which seriously affects the growth of fish. Moreover, most of these ponds have a flat bottom structure. It needs to be flushed repeatedly during sewage discharge, which wastes a lot of manpower and material resources. Moreover, the feces and residual bait of the fish stay in the culture pond and slowly dissolve in the water body, which easily leads to poor water quality and makes the cultured fish sick.

Therefore, aiming at the deficiencies in the sewage discharge and purification aspects of the existing indoor circulating water fish ponds, it is necessary to design a device for efficient sewage discharge and water purification in indoor fish ponds, which is very necessary.

Utility model content

The technical problem to be solved by the utility model is to provide an aquarium with high-efficiency sewage discharge and water purification, which can reduce water discharge, improve water purification efficiency, and save time and effort.

The technical scheme of the utility model is composed of a purification pond, a fish pond, a water pump, a water pipe, filter cotton, fine stones, valves, and a nylon net. It is characterized in that a layer of nylon net is hung horizontally near the bottom of the fish pond, so that the fish The feces and residual bait will gradually sink through the nylon net, but the cultured fish can only stay in the upper layer with better water quality due to the barrier of the nylon net; Sewage pipe, the bottom of the sewage collection pipe is equipped with a valve, so that the feces and residual bait of the fish will gradually sink into the sewage collection pipe, and these dirt can be discharged as long as the valve is opened regularly; the purification tank is installed near the bottom There is a bottom plate, drill fine holes on the bottom plate, spread fine stones on the bottom plate, and spread a layer of filter cotton on the fine stones, and breed sucker fish, basket fish and other fish with scavenger function that can eat residual bait and dirt in the upper water body of the purification tank so that the water in the purification pool can be purified efficiently; the bottom surface of the purification pool is conical with a downward angle of 45 degrees, and the sewage collection pipe is connected in the middle, and the bottom of the sewage collection pipe is equipped with a valve, so that the fish feces and residual bait It will gradually sink into the sewage collection pipe, and the sewage can be discharged as long as the valve is opened regularly; the purification tank is adjacent to the fish pond, and there is a culvert at the bottom of the two. A water pump is installed on the upper part of the purification tank. The water inlet pipe is positioned in the water body of the purification pond, and the water outlet pipe is positioned at the top of the fish pond, so that the water pump in the fish pond and the purification pond can form circulating water when the water pump is started.

The utility model has the advantage that the bottom surface of the fish pond and the purification pond form a conical shape with a downward angle of 45 degrees, and the sewage collection pipe is connected in the middle, and the bottom of the sewage collection pipe is equipped with a valve, so that the feces and residual bait of the fish will gradually fall down. It sinks into the sewage collection pipe, and the sewage can be discharged as long as the valve is opened regularly, which saves time and effort, and can save water resources; the middle and lower parts of the fish pond are equipped with nylon nets, so that the fish pond forms a cage type structure, the feces and residual bait of the fish will gradually sink through the nylon net, but the cultured fish can only stay in the upper layer with better water quality due to the barrier of the nylon net, which provides a good growth environment for the fish; There are physical purification facilities with fine stones and filter cotton, and sucker fish, basket fish and other fish are cultivated in the upper part of the purification tank to play a role in biological purification. The water in the purification tank is efficiently purified through physical and biological double layers; the whole device structure is simple, The utility model has the advantages of high efficiency, low cost and easy popularization.

Detailed ways

The cage-type multi-stage self-purifying circulating water fish pond (see attached picture) is composed of purification pond 1, fish pond 9, water pump 2, water pipe 3, filter cotton 4, fine stone 5, valve 8, and nylon net 10. Pond 9 becomes square, and side length is 2.0 meters, and depth is 1.8 meters, hangs one deck nylon net 10 horizontally at 0.4 meters from the bottom of fish pond 9, and nylon net 10 is nailed on the fish pond 9 inner walls with cement nails, The mesh of nylon net 10 is 1.5 centimetres, and the feces of fish and residual bait can sink gradually by nylon net 10 like this, but cultured fish can only stay in the better upper layer of water quality because of the barrier of nylon net 10. The bottom surface of the fish pond 9 is conical with a downward angle of 45 degrees, and the circular sewage collection pipe 7 is connected in the middle. The diameter of the sewage collection pipe 7 is 10 centimeters, and the length is 0.5 meters. 8. In this way, the feces and residual bait of the fish will gradually sink into the sewage collection pipe 7, as long as the valve 8 is opened regularly, these dirt can be discharged. The purification pool 1 is square, with a side length of 1.0 meters and a depth of 1.8 meters. A base plate 11 is installed near the bottom. The base plate 11 is drilled with 60 circular pores with a diameter of 0.5 cm. The base plate 11 is covered with fine stones 5, fine Lay a layer of filter cotton 4 on the stone 5, breed sucker fish, basket fish and other fish with scavenger effect that can ingest residual bait and dirt on the upper part of the purification tank 1, so that the water in the purification tank 1 can be efficiently purified . The bottom surface of the purification pool 1 is conical with a downward angle of 45 degrees, and the circular sewage collection pipe 7 is connected in the middle. The diameter of the sewage collection pipe 7 is 10 cm, and the length is 0.5 meters. The bottom of the sewage collection pipe 7 is equipped with a valve 8 , the excrement and residual bait of fish can sink gradually in the sewage collecting pipe 7 like this, as long as valve 8 is opened regularly these dirt can be discharged.
