Abstract

The utility model relates to equipment for aquaculture, particularly to a drainage system for an adult fish culture pond. The drainage system for the adult fish culture pond comprises an aquaculture pond body, a rotary drainage device and a residual feed excrement collector. According to the drainage system for the adult fish culture pond, the sewage is convenient to discharge when water spirally flows in the culture pond, water productions are prevented from entering into the drainage outlet due to the fact that a discharge device cover is arranged on the upper end of a return water opening, discharged sewage is collected and precipitated in the residual feed excrement collector, and upper layer clean liquid enters into the overflow pipe which is provided with the steering elbow to perform a step of secondary water purification and filtering step to save the water source, so that effects of purification and filtering are good and backflow of overflow water is prevented. A stopper is a column-shaped hollow long plug which is inserted into a discharge outlet, a plurality of draining openings are formed in a lateral wall of the upper end of the long plug, and a pipe opening of an overflow pipe is lower than the draining openings to prevent excessive drainage from spilling from a residual feed excrement device when drainage flow is overmuch.

Description

A sewage system for adult fish breeding ponds

technical field

The utility model relates to equipment for aquaculture, in particular to a sewage discharge system for adult fish breeding 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 high-density intensive breeding, it is necessary to recycle, filter, purify, oxygenate, and sterilize the backwater and sewage in the aquaculture pond for secondary use, which has achieved the purpose of saving water and maintaining the breeding environment. The sewage of the existing aquaculture pond The device is an ordinary floor drain with a filter screen. This kind of floor drain cannot separate the backwater and sewage, and when the water swirls in the breeding pond, it is not conducive to the discharge of sewage. the

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 sewage system for adult fish breeding ponds that can separate backwater and sewage, and facilitate the discharge of sewage when the water in the breeding pond is swirling.

The utility model is realized through the following technical solutions:

A sewage discharge system for adult fish breeding ponds, comprising a pot-shaped aquaculture pond body, a rotary sewage discharger and a residual bait and feces collector arranged in the center of the bottom of the aquaculture pond body, the rotary sewage discharger includes a pot-shaped sewage discharger Bottom, the backwater outlet at the center of the bottom of the sewage discharger and the sewage discharge outlet spirally downward at the bottom side of the sewage discharger. The discharge port in the center of the cylindrical pipe body and the plug provided on the discharge port, the plug is a cylindrical hollow long plug inserted in the discharge port, and a plurality of drain ports are arranged on the side wall of the upper end of the long plug, the long plug Higher than the residual bait feces collector, a sewage pipe is provided between the middle section of the residual bait feces collector and the sewage outlet, and an overflow pipe is provided on the upper section of the residual bait feces collector, and the mouth of the overflow pipe is lower than the drain port, The overflow pipe is connected to a turning elbow connected with the secondary water purification and filtering device with its opening downward, and a sewage discharge pool is arranged under the discharge port.

The water outlets are arranged vertically and become larger successively from bottom to top. the

The beneficial effects of the utility model are:

Since the bottom of the aquaculture pond body is pot-shaped to facilitate the accumulation of dirt, the bottom of the pot-shaped sewage discharger of the rotary sewage discharger in the center of the bottom is equipped with a central return port and a spiral downward sewage discharge port on the side, which can effectively Separation of backwater and sewage. When the water swirls and flows in the breeding pond, it is conducive to the discharge of sewage. The upper end of the return port is equipped with a sewage discharge device cover to prevent the aquaculture products from entering the sewage discharge port. After the sewage is discharged, the sediment is collected in the residual bait and feces collector. Qingye enters the overflow pipe with a turning elbow, enters the secondary water purification and filtration link, saves water sources, makes the purification and filtration effect better, and prevents the overflow from flowing back. The plug is a cylindrical hollow long plug inserted in the discharge port, and The long plug upper end side wall is provided with a plurality of drain outlets, and the mouth of the overflow pipe is lower than the drain outlets, so as to prevent excessive sewage flow from overflowing in the self-mutilation bait feces collector.

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 7, a rotary sewage discharger 11 and a residual bait and feces collector 9 arranged in the center of the bottom of the aquaculture pond body, and the rotary sewage discharger includes a pot-type The bottom 6 of the sewage discharger, the return port 5 located at the center of the bottom of the sewage discharger and the sewage discharge outlet 4 spirally downward on the bottom side of the sewage discharger, the upper end of the return water outlet is provided with a sewage discharger cover 1, and the residual bait and feces collector includes Cylindrical pipe body, a discharge port located in the center of the cylindrical pipe body and a plug provided on the discharge port, the plug is a columnar hollow long plug 8 inserted in the discharge port, and a plurality of Drain outlet 16, described long plug is higher than residual bait feces collector, is provided with blowdown pipe 10 between the middle section of described residual bait fecal collector and sewage outlet, and described residual bait fecal collector upper section is provided with overflow pipe 13, so The mouth of the overflow pipe is lower than the water discharge port, and the overflow pipe is connected to the turning elbow 15 with the opening downward connected with the secondary water purification and filtering device, and a sewage discharge pool 12 is arranged under the discharge port.

A water return pipe 2 connected to the water return port is inserted in the center of the drainer cover, and a water return hole 3 is arranged on the upper circumference of the water return pipe.
