Description

A sewage system for shrimp culture ponds

technical field

The utility model belongs to the technical field of aquaculture equipment, and in particular relates to a sewage discharge system for prawn breeding ponds after the transformation of original sea cucumber and shellfish breeding ponds.

Background technique

With the promotion of Penaeus vannamei aquaculture, the industrialized aquaculture model is less affected by the environment, has strong controllability, and is favored for its high aquaculture output. Many sea cucumber nursery ponds and shellfish nursery ponds have been transferred to the Penaeus vannamei aquaculture industry.

The sewage system is an important part of the shrimp culture pond, and a good sewage effect is the key to the culture. The sewage system should not only be convenient to operate, but also completely remove impurities such as residual bait and feces in the water. The traditional sea cucumber and shellfish nursery ponds are rectangular or nearly rectangular. The sewage outlets are generally set at the cultivation end, close to the sewer sewage channel. The sewage system is short to facilitate the collection of sea cucumber and shellfish seedlings when pouring the pond. However, for the culture of Penaeus vannamei, this type of sewage system is no longer suitable. During the prawn breeding process, there is often a strong aeration, so that the dissolved oxygen in the water is sufficient, so that the water body forms a flowing water flow, which is conducive to the high yield of prawns, and also concentrates the feces, residual bait and shells in the middle of the culture pond. The traditional sewage system close to one end cannot play a good role in sewage discharge. If the sewage system of the breeding pond is redesigned, it will not only bring a lot of troubles to the operation, but also increase labor and increase the cost of cultivation, and the transformed breeding pond will no longer be suitable for cultivating seedlings such as sea cucumbers and shellfish.

Contents of the invention

The technical problem to be solved by the utility model is to provide a sewage system for prawn breeding ponds. The sewage system can discharge the residual bait and feces in the middle of the culture ponds without spending too much cost, and can also be used in the culture ponds for sea cucumbers, Shellfish are not affected in any way.

The utility model is achieved through the following technical solutions:

A sewage discharge system for a prawn breeding pond, characterized in that it includes a sewage suction pipe, an exhaust pipe, a three-way pipe and a falling object;

The sewage suction pipe and the exhaust pipe are respectively glued and inserted in the two ports of the tee pipe, wherein the sewage suction pipe is laid in parallel on the bottom surface of the culture pond and extends to the middle part of the culture pond; the exhaust pipe is perpendicular to the bottom surface of the culture pond and higher than the water surface of the breeding pond;

In addition to the port connected to the sewage suction pipe and the exhaust pipe, the remaining one port of the three-way pipe is inserted into the original sewage hole of the culture pond;

The falling object is connected to the sewage suction pipe, and the sewage suction pipe is fixed on the bottom surface of the culture pond.

Further, 15 to 20 rectangular sewage suction holes are arranged at the free end of the sewage suction pipe, and the long sides of the rectangular sewage suction holes are perpendicular to the bottom surface of the culture pond.

The utility model has the beneficial effects compared with the prior art:

The utility model starts from the fact that the sewage system of the original culture pond is not convenient to discharge the middle dirt in the culture pond in the culture of prawns. Through research, it is found that in order to completely discharge the residual bait and feces in the water, the original sewage system is too close to one end of the pond. It is impossible to discharge the dirt washed into the middle of the pool by oxygen; if the oxygenation method is changed, the residual bait and feces can only be sucked out manually, which greatly increases the labor load; Adapt to the original sea cucumber and shellfish farming. The sewage discharge system of the utility model is designed on the basis of the original sewage discharge system. The sewage suction pipe and the exhaust pipe are connected by a three-way connection. The exhaust pipe is vertical to the pool surface and protrudes from the water surface to prevent the water from returning to the sewage when the sewage outlet is closed. The huge impact force pushes the pipe away; the sewage suction pipe is laid parallel to the pond floor and extends to the place where the feces and bait are concentrated in the center of the breeding pond. The pipe is fixed with falling objects to prevent rotation, and the pipe body is cut into 15-20 rectangular holes It not only increases the sewage discharge area, but also prevents shrimp from escaping; the third end is tightly inserted into the sewage discharge hole of the original culture pond, and is connected with the entire sewage discharge system; at the same time, the utility model can be disassembled at any time according to actual production needs, and the operation is simple and time-saving The utility model has the advantages of labor saving, convenient cleaning and strong practicability, and is convenient for popularization and use.

detailed description

The technical solutions of the present invention will be described in detail below through examples in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited in any form by the examples.

A kind of blowdown system of prawn culture pond, as shown in Figure 1, it mainly comprises sewage suction pipe 1, exhaust pipe 2, three-way pipe 5 and drop object 3,

The sewage suction pipe 1 and the exhaust pipe 2 are respectively glued and inserted in the two ports of the tee pipe 5, wherein the sewage suction pipe is laid in parallel on the bottom surface of the culture pond and extends to the middle part; the exhaust pipe 2 is perpendicular to the culture pond The bottom surface is higher than the water surface of the breeding pond;

Described three-way pipe, except the port that is connected with sewage suction pipe, exhaust pipe, remaining another port is inserted in the former blowdown hole 6 of culture pond;

The falling object is connected to the middle part of the sewage suction pipe, and the sewage suction pipe 1 is fixed on the bottom surface of the culture pond to avoid rotation.

The free end of sewage suction pipe is provided with 18 rectangular sewage suction holes 4, and any number of rectangular sewage suction holes in 10-20 can also be set, and the long side of described rectangular sewage suction holes is perpendicular to the culture pond bottom surface.

Example: In July 2016, Shandong Binzhou Haiyuan Nursery Farm cultivated Penaeus vannamei in the original sea cucumber nursery pond. Using this design method, PVC pipes with a caliber of 10cm were glued and inserted on the three-way pipes to serve as sewage suction pipes respectively. Pipe and exhaust pipe, the remaining one port of the tee pipe is tightly inserted in the sewage hole 6 of the original culture pond. After opening the sewage valve, within 1 minute, the dirt in the middle of the culture pond can be discharged cleanly. Bottom suction detection after sewage discharge, 100% of the feces concentrated in the middle of the breeding pond are discharged, saving time, effort and cost.
