Sewage is conveniently collected as the bottom of the aquaculture pond body is pot-shaped, the sewage is discharged by the blow-down pipe column arranged at the blow-down outlet at the center of the bottom of the aquaculture pond body through the blow-down holes formed in the blow-down pipe column, and cultured aquatic products are prevented from entering the blow-down holes as the screen mesh is arranged at each blow-down hole. By the aid of the columnar structure with the multiple blow-down holes, the sewage can be effectively prevented from blocking the blow-down holes, and sewage discharge is facilitated.

Description

A fish fry breeding pond sewage system

technical field

The utility model relates to equipment for aquaculture, in particular to a sewage discharge system for fry culture ponds.

Background technique

Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming and fence farming. High-density intensive farming uses methods such as running water, temperature control, oxygenation, and feeding high-quality bait to carry out high-density farming in small water bodies to obtain high yields, such as high-density fish and shrimp farming in running water.

In the high-density intensive fish fry culture, it is necessary to discharge the backwater with sewage in the culture pond and inject new water into the culture pond, which has achieved the purpose of saving water and maintaining the breeding environment. The sewage discharger of the existing aquaculture pond is easy for sewage Blocking the sewage outlet is not conducive to sewage discharge.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a fish fry culture pond sewage discharge system which is convenient for sewage discharge.

The utility model is realized through the following technical solutions:

A fish fry breeding pond sewage discharge system, comprising a pot-shaped aquaculture pond body, a sewage discharge outlet arranged in the center of the bottom of the aquaculture pond body, a sewage discharge pipe column with multiple sewage discharge holes and a return water set on the sewage discharge outlet The overflow pipe, the sewage discharge hole of the sewage discharge pipe column is provided with a screen, and the return water overflow pipe includes a cylindrical pipe body, a discharge port arranged in the center of the cylindrical pipe body and a plug provided on the discharge port, the plug It is a columnar hollow long plug inserted in the discharge port, the long plug is lower than the height of the return water overflow pipe, a sewage discharge pool is arranged under the discharge port, and a sewage discharge pipe is provided between the sewage discharge port and the return water overflow pipe.

The drain holes are arranged in a 30-degree helical line on the return water overflow pipe.

The beneficial effects of the utility model are:

Since the bottom of the aquaculture pool is pot-shaped to facilitate the collection of sewage, the sewage pipe column set on the sewage outlet in the center of the bottom discharges the sewage through the sewage discharge hole, and the sewage discharge hole is equipped with a screen to prevent the aquaculture from entering. Sewage hole, this kind of column type multi-drainage hole structure can effectively prevent sewage from clogging the sewage hole and facilitate the discharge of sewage. the

Description of drawings

Fig. 1 is a front structural schematic view of the utility model.

In the figure: 1. Aquaculture pond body, 2. Sewage pipe column, 3. Sewage hole, 4. Sewage pipe, 5. Backwater overflow pipe, 6. Sewage pond, 7. Water surface, 8. Long plug.

Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model includes a pot-shaped aquaculture pond body 1, a sewage discharge outlet located at the center of the bottom of the aquaculture pond body, a sewage discharge column 2 with a plurality of sewage discharge holes on the sewage discharge outlet, and The backwater overflow pipe 5, the sewage discharge hole 3 of the sewage discharge pipe column is provided with a screen, and the return water overflow pipe includes a cylindrical pipe body, a discharge port located in the center of the cylindrical pipe body and a plug provided on the discharge port. , the blockage is a columnar hollow long plug inserted in the discharge port, the long plug 8 is lower than the height of the backwater overflow pipe, a sewage discharge pool 6 is arranged under the discharge port, and the gap between the sewage discharge port and the return water overflow pipe A sewage pipe 4 is provided.

The drain holes are arranged in a 30-degree helical line on the return water overflow pipe.

Since the bottom of the aquaculture pool is pot-shaped to facilitate the collection of sewage, the sewage pipe column set on the sewage outlet in the center of the bottom discharges the sewage through the sewage discharge hole, and the sewage discharge hole is equipped with a screen to prevent the aquaculture from entering. Sewage hole, this kind of column type multi-drainage hole structure can effectively prevent sewage from clogging the sewage hole and facilitate the discharge of sewage.

During work, sewage enters the backwater overflow pipe from the blowdown hole, and the backwater overflow pipe forms a connector with the body of the aquaculture pool. Overflow from the inside of the hollow long plug and fall into the sewage tank.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. Retouching should also be regarded as the scope of protection of the present utility model.
