Description

Sewage discharge circulating water device of culture system

Technical Field

The utility model belongs to the technical field of aquaculture, in particular to a sewage and circulating water device of a culture system.

Background

The large-scale indoor culture of aquatic animals is generally carried out in a culture tank or a culture pond, certain bait is required to be fed every day in the culture process, excrement and residual bait for culturing the aquatic animals are remained in the culture pond and gradually dissolved in a water body along with the time lapse, so that the water quality is deteriorated, and the cultured aquatic animals are diseased. The fishing of the residual baits or the changing of the water after the baits are fed each time wastes time and labor.

Because of the great breed scale, trade water and generally can not draw water through the drain pump and trade water, efficiency is very slow. Therefore, a hole is reserved at the bottom of the culture tank or the culture pond for sewage discharge and water change. Normally, the hole is closed, and the hole is opened only when the sewage is drained and the water is changed. However, the aquatic organisms cultured at the moment are easy to move to the opening along with the water flow or actively, so that the aquatic organisms are easy to escape and easily block the opening.

Therefore, a sewage discharge and circulation device of a culture system is needed to be designed aiming at the problems of sewage discharge and water change in the process of culturing aquatic animals by adopting a bottom drainage culture tank or a culture pond.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a sewage circulating water device of farming systems is provided, when producing hydrologic cycle, avoid opening the aquatic livestock animal escape and the outlet blockage that trades water and lead to because of the outlet.

The utility model provides a technical scheme that its technical problem adopted is: provides a sewage-discharging circulating water device of a culture system, which is arranged in a culture tank or a culture pond with a water outlet at the bottom. The blowdown circulating water device comprises a filtering device and an oxygenation pump which are positioned at the top of the culture tank, and a silent water pump which is positioned at the bottom of the culture tank, wherein the silent water pump is connected with the filtering device through a water pipe, a groove is formed in the outer edge of the water outlet, a hollow pipe which can be freely inserted and pulled is arranged in the groove, and a water drainage hole is formed in the lower half section of the hollow pipe.

Further, the hollow pipe is a PVC pipe.

Further, the drain hole is located within 10cm of the length of the hollow tube from the end.

Furthermore, the filtering device comprises a net basket, and a piece of filter cotton is arranged in the net basket.

Furthermore, the tail end of an output air pipe of the oxygenation pump is provided with a gas stone.

Advantageous effects

Through the drain pipe of direction about but plug change, separate aquatic animals and outlet physics when the drainage, avoid because of the outlet opens the aquatic animals escape that leads to of trading water and the jam of outlet.

When the water is not changed, the section without holes of the hollow tube is arranged below, so that the excrement and the residual bait can be prevented from being accumulated at the water drainage port along with the opening of the hollow tube.

The water circulation system adopting the silent water pump and the filter screen frame ensures fresh water in the tank, and the filter cotton is only required to be cleaned and replaced at ordinary times without frequent water replacement.

The utility model discloses simple structure, it is easy and simple to handle, ability fast assembly can regard as the standard test device of complete set to use, is favorable to saving a large amount of manpower and materials.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The utility model provides a sewage discharging and circulating water device of a culture system, which is arranged in a culture tank 1 with a water outlet 3 at the bottom or a culture pond. The following description will be made by taking the sewage circulating water apparatus installed in the culture tank 1 as an example.

As shown in figure 1, the sewage circulating device comprises a filtering device and an oxygenation pump 10 which are positioned at the top of the culture tank 1 or the culture pond.

The filter device comprises a mesh basket 8 and a silent water pump 4. The net basket 8 is fixedly hung on the side wall of the top of the culture tank 1, a piece of filter cotton 7 is arranged in the net basket 8, and the area of the filter cotton 7 is larger than that of the net basket 8. The mute water pump 4 is positioned at the bottom of the culture tank 1 or the culture pond and is connected with the filtering device through a water pipe 5. The mute water pump 4 pumps water from the bottom of the culture tank 1 to send the water body, the aquatic animal manure and the residual bait upwards into the net basket 8, and the water body, the aquatic animal manure and the residual bait are discharged back into the culture tank 1 after being filtered by the filter cotton 7. The filter cotton 7 is not required to be replaced every day, and can be reused after being taken out once every two days or so for cleaning.

The oxygenation pump 10 is located breed 1 outside of jar, let in through the trachea and breed 1 the aquatic in the jar, the output trachea end of oxygenation pump 10 is equipped with air stone 2, the oxygen diffusion of being convenient for.

The outer edge of the water outlet 3 at the bottom of the culture tank 1 is provided with a groove, a hollow pipe 9 which can be freely inserted and pulled is arranged in the groove, and a water drain hole is formed in the lower half section of the hollow pipe 9. The hollow pipe 9 is a PVC pipe. The drain hole is positioned in the length of 10cm from the tail end of the hollow tube 9, and the aperture of the drain hole is smaller than that of the cultured aquatic animals.

When the water is drained, one side with the water drainage hole is inserted into the groove of the water drainage hole 3, the water flow naturally flows out from the water drainage hole by opening the water drainage hole 3, and the cultured aquatic animals are blocked by the hollow pipe 9, so that the escape of the aquatic animals and the blockage of the water drainage hole 3 caused by the open water change of the water drainage hole 3 are avoided. After the drainage outlet 3 is closed after the drainage is finished, the hollow pipe 9 can be taken out, the up-down direction is turned, the section without holes of the hollow pipe 9 is placed in the groove, and the excrement and the residual bait can be prevented from being accumulated at the drainage outlet 3 along with the opening of the hollow pipe 9 when the drainage is not carried out.
