The super micro bubble water body oxygen increasing device is suitable for the occasions, such as the culture of live fish, integrated culture of fish, green agricultures, and the like.

Description

The soaked body oxygen-increasing device of a kind of ultra micro

Technical field:

The utility model relates to a kind of water body oxygen-increasing device, particularly relates to the soaked body oxygen-increasing device of a kind of ultra micro.

Background technology:

In the hotel, restaurant, supermarket, food market live fish support and occasion such as intensive feeding temporarily, all is that to adopt the blowing aeration mode be water oxygenation basically.At present the blowing aeration mode has various ways, and the gas that is produced as air pump, Cyclone wind motor etc. directly enters diffuser in the water by pipeline, as gas stone, membranous disc etc., produces bubble and reaches the purpose that water body is increased dissolved oxygen.But all bigger than normal because of bubble diameter, cause water very low to the absorption ratio of oxygen, the absorption ratio of general oxygen has only 3%～5%, therefore, reduces bubble diameter, improves the absorption ratio of oxygen in water body, just becomes a research topic.For a long time, progressively take to have realized microbubble by research and development by technology such as ultrasonic, infrasonic sound, machinery, jets, the bubble size level that produces differs, be generally 0.5 μ m～10 μ m, though, the bubble that produces can reach the purpose that water body is increased dissolved oxygen, but these technical costs height are not suitable for using in aquaculture.In addition, at above-mentioned situation, there is the designer once to propose a kind of ultra micro bubble oxygen-increasing device, this ultra micro bubble bubble diameter that oxygen-increasing device produced is about 80 μ m, and oxygen absorption rate is 15%, and is respond well,, supplementary structure is many, cost is high, Installation and Debugging inconvenience.

Summary of the invention:

The purpose of this utility model is to provide a kind of improved ultra micro soaked body oxygen-increasing device, and it not only can make the bubble that is produced that water body is reached the purpose that increases dissolved oxygen effectively, and, simple for structure, with low cost, easy to operate.

In order to realize that above-mentioned purpose the utility model proposes following design: the soaked body oxygen-increasing device of a kind of ultra micro of the present utility model comprises a self priming pump, the delivery port pipe, outlet pipe, outlet water control valve, manometer, the energy release, water sucking mouth pipe and pond, be serially connected with a described outlet water control valve between delivery port pipe on the described self priming pump and the described outlet pipe, also be serially connected with a described manometer on the described outlet pipe, the place, other end end of described outlet pipe is connected with a described energy release, the other end of the water sucking mouth pipe on the described self priming pump is placed in the described pond, also be provided with an air inlet pipe on the relative pump case in impeller input port in the described self priming pump, the place, other end end of the described air inlet pipe intake valve that has been connected and fixed successively, spinner flowmeter.

Because the utility model has improved existing a kind of ultra micro bubble oxygen-increasing device, and by one air inlet pipe, intake valve and spinner flowmeter being installed in the pump case processing relative with described self priming pump impeller input port, utilize impeller in drainage procedure, the negative pressure that its place, impeller input port produces is air-breathing automatically, continues suction and air like this, has formed air-water mixture, by improving, structure compared with the existing, and is more simple, and cost also reduces about 50%.After the enforcement, show that the diameter range of bubble is 10～120 μ m, average diameter is 40 μ m, and the standard oxygen transfer rate is 1.908kg (O ₂)/h, the absorption ratio of oxygen is 36%, increases by 21% than before improving, dynamic efficiency is 3.469kgO ₂/ kwh, oxygenation effect is remarkable, and it is loaded down with trivial details to have remedied the aerator structure that exists on the current market, price height, the low phenomenon that waits deficiency of oxygenation efficient.

Description of drawings:

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation of the soaked body oxygen-increasing device of a kind of ultra micro of the present utility model.

Embodiment:

Below with reference to accompanying drawing the soaked body oxygen-increasing device of a kind of ultra micro of the present utility model is described in further detail.

With reference to Fig. 1, the soaked body oxygen-increasing device of a kind of ultra micro of this utility model is made up of a described self priming pump 1, described delivery port pipe 2, described outlet pipe 3, described outlet water control valve 4, described manometer 5, described energy release 6, described water sucking mouth pipe 7, described pond 8, described air inlet pipe 9, described intake valve 10 and described spinner flowmeter 11.

Described outlet water control valve 4 is serially connected between the delivery port pipe 2 and described outlet pipe 3 on the described self priming pump 1, described manometer 5 is serially connected on the described outlet pipe 3, described energy release 6 is connected in the place, other end end of described outlet pipe 3, the other end of the water sucking mouth pipe 7 on the described self priming pump 1 is placed in the described pond 8, described air inlet pipe 9 is fixed on the relative pump case in impeller input port in the described self priming pump 1, described intake valve 10, described spinner flowmeter 11 is connected and fixed successively at the place, other end end of described air inlet pipe 9.

When the soaked body oxygen-increasing device of a kind of ultra micro of the present utility model uses, start described self priming pump 1, described self priming pump 1 wheel rotation is carried out draining, simultaneously, utilize the described self priming pump 1 impeller negative pressure that its impeller center produces in drainage procedure by described spinner flowmeter 11, described intake valve 10 and described air inlet pipe 9 are air-breathing automatically, make described self priming pump 1 in the course of the work, continue suction and air, under the high-speed stirred of impeller, increase oxygen contacts with water, and fully mix, form air-water mixture, when the described delivery port pipe 2 of air-water mixture process, described outlet water control valve 4, behind described outlet pipe 3 and the described energy release 6, formed countless micro-bubble directly enters in the water body of required oxygenation, bubble diameter has increased the contact area of oxygen and water greatly at micron order, and, the time of staying in water body is longer relatively, so the absorption ratio to oxygen improves greatly, to the abundant oxygenation of water body, and respond well.

Simple in structure, cheap, peace that a kind of ultra-microbubble water-body oxygen-increasing device of the present utility model has Debug that examination is simple and easy, control air inflow convenience, oxygenation efficient height, characteristics that power consumption is low, be applicable to The occasions such as live fish is supported temporarily, intensive feeding, green agriculture.
