Abstract

The invention relates to a pond aerator. A main consists of a plurality of sections, which are connected together through tees, the head end of the first section is connected with the blowing nozzle of a fan through a pipeline, the lower orifice of the tee between each two sections of the main is connected with the top end of a branch pipe, the bottom ends of the branch pipes are connected with a return water pipeline, valves are respectively arranged on both ends of the return water pipeline, the branch pipes are made of elastic material, and a plurality of exhaust holes are equidistantly arranged on the surface of each branch pipe. The pond aerator has the advantages that: the weed pest can be prevented, the production efficiency is high, the cost is low, and the pond aerator h is convenient to operate.

Description

A kind of pool oxygenation device

Technical field the present invention relates to a kind of pool oxygenation device.

The background technology pool oxygenation is that aquaculture field is to guarantee that aquatic products safety such as fish, sea cucumber increase, and prevents crop smothering, improves the important breed means of output; Especially in the winter time, because the fishpond water level is low, the dissolved oxygen amount in the water of the freeze-up back of ice and snow exhausts easily ahead of time; When water oxygen gas content was lower than 3 mg/litre, fish were with regard to easy anoxic and death. so will there be sufficient oxygen in the fishpond of surviving the winter, this is the key that guarantees the fingerling safe overwintering; At present, some aquaculture enterprises adopt the method for spraying chemicals that oxygenation is carried out in the pond basically, though chemical enhancement is a kind of oxygenation way fast and effectively; But in use, still exist deficiency:

1, input is inhomogeneous, causes the local anoxic in pond easily.

2, throw in medicine and too much can endanger the fish body.

3, the cost of chemicals is higher, generally when rescuing the fingerling floating head, just uses.

4, oxygenation time weak point can not continue, effectively guarantee the pond amount of oxygen.

Summary of the invention the object of the present invention is to provide a kind ofly improve the aquatic products production environment, prevent crop smothering, production efficiency is high, with low cost, the pool oxygenation device being convenient to operate.

The present invention mainly comprises blower fan and oxygen increasing equipment, and wherein oxygen increasing equipment is by the person in charge, and arm and water return pipeline are formed; The said person in charge is processed by sun-proof material, and for example pvc pipe preferably is responsible for and is made up of plurality of sections; And link to each other through three-way pipe between every section person in charge; Link to each other with the blowing mouth of blower fan through pipeline at first section head end, and be provided with valve, also be provided with valve at the end of the final stage of above-mentioned arm in the junction of above-mentioned pipeline and first section; Smooth and easy for jet and exhaust, the diameter of each of the above-mentioned person in charge section is different, promptly by be responsible for head end to every section terminal diameter by greatly extremely little laying; Three-way pipe bottom bore between every section of the said person in charge links to each other with the top of arm; The end of said arm links to each other with water return pipeline; Promptly be provided with the through hole corresponding with above-mentioned three-way pipe on the surface of water return pipeline; This through hole links to each other through straight-through tube connector with the end of arm, is respectively equipped with valve at the two ends of above-mentioned water return pipeline; Above-mentioned arm by elastomeric material for example rubber process, offer several pin holes, i.e. air vent at the surperficial equidistance of arm.

The present invention is work like this:

The person in charge is placed the long pool side in pond, and lay at the bottom of pasting the pond, bye-pass and water return pipeline be drawout in the pond successively, and blower fan places pool side to get final product.During use, open all valves earlier, restart blower fan; After treating the interior water emptying of pipeline, close the valve of being responsible for end and water return pipeline successively, this moment, gas was discharged by the air vent on the arm; Because adopt the micropore oxygenation way, during inflation, the air vent on the arm opens under the pressure of pressure; Close voluntarily owing to elastic force during shutdown, anti-sealing pours in down a chimney.

The present invention has following advantage:

1, adopt bottom oxygenation, gas sheds at the bottom of by the pond, avoids the local anoxic in pond.

2, full pond is passed through in exhaust, and full pond running water does not have the dead angle, effectively suppresses crop smothering and takes place.

3, the oxygenation time long, continue, effectively guarantee the pond amount of oxygen.

4, little to the harm of fish body, enhance productivity, shorten culturing time.

5, with low cost, long service life can be used in the many ponds of a machine.

Description of drawings Fig. 1 is a structural representation of the present invention.

Embodiment is as shown in Figure 1, and being of a size of 100x 500m with the pond is example:

Being responsible for 1 is pvc pipe, and total length is 500m, and the person in charge forms by three sections; Every section diameter is respectively 75mm, 63m and 50m; And every segment length is 4m, and links to each other through three-way pipe 2 between every section person in charge, links to each other with the blowing mouth of the fan blower 3 of 5.5kw driven by motor through pipeline at first section head end; And be provided with valve 4 in the junction of above-mentioned pipeline and first section, also be provided with valve 5 at the end of the final stage of above-mentioned arm; The bottom bore of the three-way pipe between every section of the said person in charge links to each other with the top of arm 6, and said arm is a rubber tube, and every is 100m, and every at a distance from the 5cm pin hole that to offer a diameter be 1mm on the surface of arm, promptly air vent 7.The end of arm links to each other with water return pipeline 8, and the length of said water return pipeline is 500m, and diameter is 6mm, is respectively equipped with valve 9 at the two ends of water return pipeline; Every separated 4m offers the through hole corresponding with three-way pipe 10 on the surface of water return pipeline, and this through hole links to each other through straight-through tube connector 11 with the end of arm.

Claims
