Abstract
A device for adding a gas to a liquid, comprising an elongated housing that is submersible in the liquid. The housing has inlet openings for gas and liquid, respectively. An axle situated in the housing is, at its first end, connected to a motor, and at its second end is provided with a pump vane, wherein a mixture of gas and liquid is discharged in the vicinity of the pump vane. A gas tube in the housing communicates with the first inlet opening for gas,a nd is provided with a nozzle with openings. The nozzles is situated in a venturi, and the gas tube is controllable in the longitudinal direction, so that the position of the nozzle in relation to the venturi can be changed.
Description
The present invention relates to a kind of gas be added the device of liquid, especially for a kind of device of fish culture box and cleaning technique aspect, preface part as claimed in claim 1 is described.Device of the present invention is specially adapted to box for breeding.
In liquid, fill and add gas multiple reason is arranged,, float,, or carry out oxidation etc. to the water of box for breeding (a plurality of casees and big pond) to the biofilter oxygenation for making the tank between cleaning Vehicle as in case water, adding anesthetic gases for the fish that kills in the box for breeding.These tasks can be finished with different equipment at present, inflate and master the ventilating shaft system as sprayer, jet pump, oxygen adsorption tower, pond.
Particularly the various devices of the consumption of many minimizing water have appearred in continental rise fish farm recently, as the bridge filter of sprayer is housed.In order to keep the correct hydraulic pressure relation in the box for breeding, adopt the method (Xiang Shuizhong blows with agitate water) of huge pump to need a large amount of energy.Coming to create best hydraulic pressure for large water tank in this way is practically impossible.
United States Patent (USP) 4,844, disclose for No. 843 a kind of in liquid the device of filling gas, both have just mixed in filling.This device has an elongated tubular of carrying liquids and gases and one to be contained in the agitator of the propeller type that is driven by motor in this pipe exit, so that liquids and gases are mixed well, and in the mist propelling liquid memory.Carry more gases to liquid memory if desired, then can improve the speed of screw.But the gas flow that this device is increased in the filling liquid will produce the side effect that changes discharge relation.Improve the speed of screw and carry more gas, the liquid flow in the holder is accelerated to liquid.
Therefore, the objective of the invention is to provide a kind of like this device that adds gas that fills in liquid, promptly the hydraulic pressure of gas flow and tank (flow velocity) can be distinguished control individually.Spray amount, pressure and the direction of gas should be controlled, so that obtain best case hydraulic pressure under various working condition.
Purpose of the present invention is achieved by described each feature of claim 1.Further feature is clearly described in other claim.
Below by embodiment and accompanying drawing the present invention is explained in detail.
Fig. 1 is the longitudinal section of first most preferred embodiment of the present invention.
Fig. 2 is the venturi tube of the embodiment among Fig. 1 and the longitudinal section of blast tube.
Fig. 3 is the longitudinal section of second most preferred embodiment of the present invention.
Device of the present invention shown in Fig. 1 is denoted as 1.This device 1 has the pump 2 of a band motor 3, and motor and a working shaft 4 join.The outer end of working shaft 4 joins with pump blade 5.Working shaft 4 is contained in 6 li on a columnar shell, and the part of axle is under water during work, shown in the waterline of describing among the figure.In shell 6, one first air intake 8 is arranged on the waterline, one second water inlet 9 is arranged under the waterline.
A tracheae 7 is equipped with around working shaft 4 in middle part at shell 6, and Fig. 2 is the clear schematic diagram of this pipe.There is an air intake upper end of tracheae 4 (annotation of translation: seemingly should be tracheae 7), and the lower end of tracheae and nozzle 11 join, and is distributed with many holes 12 around the nozzle.The nozzle 11 that has many holes 12 by a venturi tube 13 around, venturi tube is connected with a pump box 14.Can control by a controller 15 on the longitudinal direction of tracheae 7 in shell 6.Controller 15 has the bracket 16 and the installation bracket 18 that join with shell 6.A square platform 20 in bracket 18 and the shell 6 links to each other.Side's platform 20 is contained on the upper mounted plate 21 that joins with glass tube 7, and can move with respect to shell 6.Unclamp hold-down screw 19 and rotate adjustment screw 17, when hold-down screw 19 slided in the groove (not shown) on shell 6 walls, this upper mounted plate 21 can movable glass pipe 7.Like this, when glass tube 7 slided into the bottom plate 22 that is contained on shell 6 inwalls, glass tube just can be up and down in shell 6.
Around pump blade a jet pipe 23 is housed, 90 ° of (see figure 1)s of this canal curvature, stretching out makes it parallel with shell 6.Jet pipe 23 also can otherwise be installed, for example, when raising flatfish, jet pipe 23 should with parallel installation at the bottom of the rearing-box.Longitudinal direction along jet pipe 23 is provided with many spray orifices 24.These spray orifices are preferably with closing type control device (not shown), and they just can be closed individually respectively or be controlled like this.Be on the end of the above jet pipe 23 of the water surface pressure controller 25 is housed, it plays the function of pressure indicator and alarm.
During work,, motor 3 makes pump blade 5 rotations thereby driving working shaft 4.Water is sucked pump box from second inlet 9, and water is sprayed by the spray orifice of jet pipe 23.In addition, air sucks from first inlet, and sucks by the hole on the nozzle 11 of blast tube 7 12.
Infiltrate the water with the form of bubble from the air of nozzle bore 12 inspirations.These bubbles are extended under the negative pressure that venturi tube 13 is created.When water when the venturi tube 13, the whipping of pump blade becomes many minute bubbles with bubble splitting, and it can be distributed in the water from jet pipe 23 preferably.
If jet pipe 7 (annotation of translation: seemingly should be jet pipe 23) has changed with respect to the position of venturi tube 13, then the amount of water/gas of mixing in the pump blade 14 (annotation of translation: seemingly should be pump box 14) of inspiration also can increase thereupon or reduce.This effect is that the effect because of venturi tube obtains, and the variation of the cross section of water inlet makes the water speed in the venturi tube and the water yield in the pump box 14 reduce.Change the water flow velocity in the case if desired, then can realize, also can realize by the cross section of the water inlet of the nozzle in the venturi tube 13 11 with change by the speed that changes pump blade 5.Can improve or reduce the effect and/or the stream of mist with the method for the cross section of number that changes the spray orifice 24 on the jet pipe 23 and spray orifice.The speed sample use same pump just can be within a large range for the fish culture boxes of different sizes provide turbulent flow preferably, and make different big or small particulates floating.
Fig. 3 is second embodiment of the present invention.In this embodiment, be not only to suck from inlet 8 air by pump blade 5, also can suck by multistage pump 27.In addition, is furnished with a buoy 26 for installing 1, to guarantee the correct working level in liquid.
Nozzle 11 is with respect to the position of venturi tube 13, and the speed of pump blade 5 also can be controlled automatically.Can adopt electronic and/or hydraulic means is realized automatic control according to the concentration of desired flow rates/flowing relation and oxygen.
Those skilled in the art will be clear that also have other scheme within the scope of the invention.For example, motor can flatly be contained in below the water surface, adopts minor axis to connect pump blade.The heat energy of motor is fed to the water in the case in such an embodiment.
