Description
Technical field
The utility model is related to a kind of recirculated water oxygenation fields, and in particular to fish bowl circulating water oxygen-increasing device.
Background technology
In recent years, with rapid economic development and the improvement of people's living standards, ornamental fish tank aquarium is set in family
Ratio it is more and more.It, can be the excrement of fish, swill and rotten due to the presence of bacterial digestion in nature
Plant etc. decomposes, and nitrobacteria can only survive in the filter material of lautertuns in family's fish jar aquarium, it is therefore desirable to use
Water pump gets up the Static Water cycle in aquarium, is brought into what nitrobacteria continued in aquarium when passing through filter material, to reach
The ecological balance, and to have enough dissolved oxygen amounts in water is the key element of nitrobacteria existence, it is ensured that aquarium water quality is steady
It is fixed.
Water body dissolved oxygen is mainly realized using oxygen increasing pump in aquarium at present, basic functional principle is exactly using external energy
On the basis of source (power supply or compressed gas), air is pressed into water body, so that water body is contacted with air and realizes oxygenation.Existing increasing
Oxygen pump technology oxygenation efficiency is low, and operating cost is high, and oxygenation pump structure is complicated, and the leather plug proportion of goods damageds are high, service life and reliable
Property it is poor, it is most important that the noise of oxygen increasing pump is very big, since its operation principle is reciprocating extruding leather plug, vibration sense very
By force, and family's fish jar aquarium is usually all placed on quiet interior, and being compatible with the environment property of oxygen increasing pump is excessively poor.
Utility model content
The purpose of this utility model is to overcome the deficiencies of existing bleeding technique, provide a kind of simple in structure, reliability
It is high, cheap, small and efficient, mute family's aquarium aeration device completely may be implemented.
The utility model adopts the following technical solution realizes：
A kind of passive type venturi automatic aerator, including automatic aerator main body, stud valve rod, spanner, connection plug and air
Conduit, fish bowl circulating water pipeline are connected with the Venturi tube structure of automatic aerator ontology, and the automatic aerator body exit side can connect
One section of short piece is inserted under aquarium liquid level, to reach muting function, is adopted between the automatic aerator main body and front and rear pipes
Coordinated with transition.
Further, it is solid that the automatic aerator body interior, which has the Venturi tube structure of cross-sectional constriction, inlet and outlet direction,
Fixed, it can not exchange.
Further, it is laterally equipped with the air admission hole entered for moving air among the automatic aerator main body, this air admission hole
It is highly desirable on fish jar liquid level, if the height of this air admission hole under fish jar liquid level, need using the connection insert
Head connection air conduit, the top of the air conduit need on fish jar liquid level.
Further, the automatic aerator main body center top is equipped with regulating valve seat, the regulating valve seat middle part and air admission hole
Connection.
Further, by the stud valve rod screw in valve seat in, adjust oxygenation amount number.
Further, guiding beveling pipe, the guiding beveling are connected at the regulating valve seat of the automatic aerator body interior
For the notch of pipe horizontal by 55~60 degree of angles, the export direction for being oriented to beveling pipe need to be along recirculated water flow direction.
Compared with prior art, the utility model has the advantages that：
The utility model uses venturi principle, the caliber in automatic aerator body midsection position end face to reduce suddenly, cause
Cross-sectional flow increases and pressure reduces suddenly, and when it is less than atmospheric pressure, air enters from air admission hole and mixes in water, forms gas
Bubble, since tail portion caliber increases back full size, gassiness water volume flow rate reduces, and pressure is restored to arrival end hydraulic pressure, by the water of gassiness
Body is spurted into water body.
The utility model has both the function of importing air and fragmentation bubble, after sucking air, due to violent with tube wall
Collision forms a large amount of small bubbles and has submitted oxygenation efficiency significantly to increase the contact surface area of gas and water body.By
In the presence of stud valve rod and valve seat, effective, the quick control of oxygenation amount may be implemented in the utility model.
The utility model uses passive design, only by the circulating water flow of fish jar, does not need the additional external energy.
The utility model is simple in structure, reliability is high, it is cheap, small and efficient, can be achieved on completely it is quiet
Family's aquarium aeration device of sound, therefore there is prodigious promotion prospect and social demand.

Specific implementation mode
The utility model is described in further detail with specific implementation below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of passive type venturi automatic aerator includes automatic aerator main body 1, stud valve rod 2, spanner
3, connection plug 4 and air conduit 5, fish jar aquarium recirculated water are approaching at cylinder, pass through automatic aerator main body in pipeline and Fig. 6
1 inlet side is connected, and by the present apparatus, there is automatic aerator main body 1 throat of Venturi tube structure to design, according to Bernoulli equation,
The flow velocity of throat increases and pressure reduces, and air is entered by the air inlet 7 being connected with 1 main pipeline of automatic aerator main body in recirculated water
And it is mixed, since the inside extending tube road of air inlet 7 and valve seat 6 is rectangular, the air being brought into can be sent out with recirculated water and tube wall
Big air bubble fragmentation can be very tiny bubble, significantly improve oxygenation effect by raw sharp impacts.The water body of gassiness from
The outlet side of automatic aerator main body 1 is flowed out into cylinder in Fig. 6.
Further, in order to reach complete muting function, need the outlet side connection of automatic aerator main body 1 in figure 6 a bit of
The outlet end of pipeline, pipeline should go deep under the liquid level of fish jar aquarium, and the vertical height of the outlet end ensured is less than
Aquarium liquid level.
Further, the depth of the different precession valve seats 6 of the stud valve rod 2 in Fig. 6 can be used, control air admission hole 7 is opened
Close specification, including shut and open completely, can adjust according to demand air inflow number, for certain water plant culturing jars logical
The present apparatus can be used when entering carbon dioxide and close oxygen-supplying function.
Further, Fig. 2 shown devices are the configuration without air conduit 5, need to be installed on liquid level, are ensured
Air inlet 7 is directly connected to air.When the present apparatus is located in water body, the configuration shown in FIG. 1 with air conduit 5 need to be used,
Air conduit 5 is connected on air admission hole by connection plug 4, the vertical height of the upper port of the air conduit 5 needs
Higher than fish jar liquid level, guarantee and air communication.
In the air inlet 7 and air conduit 5 of the present apparatus must there are one component be placed on liquid level with atmosphere, work as cycle
Water driving force disappear when, can anti-water-stop body suck-back, due to negative pressure generate cycle aqueous reflux when, can pass through supplement air balance pressure
Power.
The examples detailed above of the utility model, the only preferred implementation method of the utility model, and not the utility model
The restriction of occupation mode.
