Industrialized circulating-water culture pond water-level control and sewage discharging integrated device

Abstract

The invention discloses an industrialized circulating-water culture pond water-level control and sewage discharging integrated device. The industrialized circulating-water culture pond water-level control and sewage discharging integrated device includes a water tank main body arranged on the side wall of a culture pond; a water inlet and a water outlet are formed in the bottom of the interior ofthe water tank main body; the bottom of the water outlet is communicated with a main water return pipe of the culture pond through a pipeline; a three-way joint is connected to the bottom of the waterinlet through a vertical pipe, and two other connection ends of the three-way joint are communicated with a sewage discharging pipe and a main water discharging pipe respectively, wherein the main water discharging pipe is arranged at the bottom of the culture pond; a plug mechanism is arranged inside the water inlet and is located between the water inlet and the three-way joint. The industrialized circulating-water culture pond water-level control and sewage discharging integrated device is reasonable in structural design and convenient to operate and can completely replace a current ball valve or a butterfly valve or an electromagnetic valve or a pneumatic valve or a lifting valve, the material cost is greatly reduced, the manual operation cost and the pipe and trench building cost aregreatly reduced, and pipe pre-embedded sewage discharging can be achieved.

Description

technical field [0001] The invention relates to the technical field of industrial circulating aquaculture pools, in particular to an integrated water level control and sewage discharge device for industrial circulating aquaculture pools. Background technique [0002] In recent years, due to environmental pressure, closed factory recirculating aquaculture has become the only way for the development of aquaculture industry, and it is an inevitable choice for the future aquaculture industry. In the process of recirculating aquaculture, the structural design of the aquaculture pond will affect how to quickly discharge sewage, exchange water, clean the fish pond and its manual operating costs, etc. [0003] At present, when domestic and foreign farm enterprises are building breeding plants and breeding ponds with a diameter ≥ 2m, the water level control of the breeding pond is often done at the side of the pond, which is convenient for manual operation, and often adopts PVC casin...

Problems solved by technology

[0003] At present, when domestic and foreign farm enterprises are building breeding plants and breeding ponds with a diameter ≥ 2m, the water level control of the breeding pond is often done at the side of the pond, which is convenient for manual operation, and often adopts PVC casing. First, it takes up space. Large, but manual operation is more laborious; in order to drain, empty, and clean fish ponds during the breeding process, the construction of the breeding pond is accompanied by the construction of breeding pipes and ditches. It is necessary to install a ball valve or a butterfly valve at the outlet pipe at the bottom of the fish pond for regular emptying of the fish pond First, the cost of ball valve or butterfly valve is expensive and easy to break, but it will increase the operating cost of artificial ditches. Third, the cost of supporting the construction of breeding pipelines and ditches is huge. To achieve a complete emptying effect, it is easy to breed bacteria; some breeding companies choose to use lift valves instead of ball valves or butterfly valves. Although this is convenient to operate, its structure is slightly complicated and easily deformed under the impact of water; Realized in the ditch, if the farmers adopt the pre-buried pipeline drainage method, it will be difficult to play a role; some farmers choose to use solenoid valves or pneumatic valves to discharge sewage regularly, one needs energy consumption, but the poor stability is easy to break, which will greatly affect the use efficiency
