Description

A kind of aeration device for aquaculture tank bottom pipeline

technical field

The utility model relates to a water body oxygenation device, in particular to a pool bottom pipeline oxygenation device in the process of aquaculture.

Background technique

At present, in the process of aquaculture in ponds, due to the high breeding density, the oxygen content in the water is reduced, especially in high temperature and sweltering weather, and aquatic animals such as fish and shrimp will surface without sufficient oxygen. Oxygen. At this time, if the oxygenation in the pool is not increased, the growth of fish and shrimp will be affected. The traditional method is to use a point-type centralized oxygenation device. In actual use, the oxygenation uniformity of this point-type centralized oxygenation device is poor. Oxygenation is not effective. There are also waterwheel type aerators and low-spray aerators, but during the breeding process, the dissolved oxygen at the bottom is below 4mg/L, the water quality at the bottom deteriorates, and it is easy to breed bacteria, which cannot meet the growth of fish and shrimp. Toxic substances such as ammonia nitrogen, nitrous nitrogen, and hydrogen sulfide cannot undergo normal degradation reactions, resulting in the deposition of these substances at the bottom of the pool, causing the death of fish and shrimp.

Chinese Patent No. 200620062400.6, titled "Culture Pond Oxygenation Device", discloses an oxygenation device composed of a blower, a main air pipe, some buried branch air pipes and some stomata pipes, and the buried branch air pipes are evenly distributed. Distributed under the mulch film at the bottom of the pool, a stomata pipe is installed on the branch air pipe, and at least one vent hole is formed on the stomata pipe, through which aeration is made into the pool to increase oxygen. Although the patent solves the problem of uniform aeration, in the process of actual use, it will be found that the diameter of the vent hole on the stomata tube is fixed. If it is poured into the stomata pipe, it will cause blockage and sludge deposition in the pipe. If it is not cleaned for a long time, it will affect the normal use.

Utility model content

The technical problem to be solved by the utility model is to provide a pool bottom pipeline oxygenation device which has a simple structure, does not cause back-absorption of vent holes, and ensures sufficient oxygenation of the cultured water body.

The technical problem solved by the utility model adopts the following technical solutions to realize:

A tank bottom pipeline aeration device in the process of aquaculture, mainly including an aerator, characterized in that: the aerator is connected to a main pipeline for gas transmission through a connecting pipe, and several circular tube-shaped pipes are connected to the main pipeline. Oxygenation pipe, the aeration pipe extends into the culture water body, and one end of the aeration pipe extending into the pond is closed, and at least one row is opened on the pipe wall, and some micro-slit exhaust holes consistent with the axis direction of the circular pipe.

The distance between each adjacent aeration pipe is between 1-1.5m, which is used to maintain sufficient circulation of the aquaculture water body and facilitate feeding and growth of fish and shrimp.

The distance between the adjacent exhaust holes on the aeration pipe on the axis is between 25-40 mm, which is used to uniformly maintain sufficient dissolved oxygen in the aquaculture water body.

The diameter of the oxygen increasing pipe is between 8-30mm.

Described aerator can adopt blower fan, blower, air compressor to replace.

In the technical solution of the utility model, micro-slits are provided on the circular tube wall, that is, long linear gaps consistent with the axis of the circular tube are opened. When the gas in the tube reaches a certain pressure, it can expand and blow open the gaps to fill the pool. When the pressure air source of the aerator is turned off, the pressure inside the tube loses pressure, and the outer wall of the round tube receives the pressure of water and the force of the tube wall itself shrinking toward the axis to close the gap. At this time, the water outside the round tube cannot return. Irrigation will not bring in silt and cause blockage of the aeration pipe.

The further technical solution of the utility model is that when the main pipeline is arranged, it is extended to the adjacent aquaculture water body, and the aeration pipe is connected in the adjacent aquaculture water body, and the aeration pipe is connected to the bottom of the pool, which greatly improves the working efficiency. Reduced the cost of purchasing aerator equipment.

The beneficial effect of the utility model is that the aeration pipe extends from the water surface to the bottom of the water, and through the micro-slit oxygenation, not only can the aquaculture water body be uniformly and three-dimensionally increased and dissolved oxygen, and the silt impurities are prevented from flowing backward from the vent hole, but also The installation is simple and the operation is convenient, which greatly improves the work efficiency.
