Specific implementation mode
For that can further appreciate that the utility model content, feature and effect of the utility model, the following examples are hereby given, and
It is described in detail with the accompanying drawings as follows：
It please refers to Fig.1 to Fig. 2, a kind of offshore platform microorganism transfer drive medicament feeding device, including agitator tank 1 and dry powder can
2；The agitator tank 1 is externally provided with venturi mixer 3；The venturi mixer 3 includes entrance 3-1, contraction section 3-2, larynx
Road 3-3, diffuser 3-4 and the feed pipe 3-5 for being located at contraction section 3-2 and the joints venturi 3-3.
It is equipped with high service device 4 in the entrance 3-1；The dry powder can 2 is connect with the feed pipe 3-5, so that
Medicament in dry powder can 2 enters venturi mixer 3；The diffuser 3-4 is connect with the agitator tank 1；Entrance 3-1 enters
High pressure water mixed in the venturi 3-3 with the medicament that feed pipe 3-5 enters, and flow into agitator tank 1 through diffuser 3-4.Dry
Between powder tank 2 and venturi mixer 3, it is equipped with the manually-operated gate 5 of control medicament addition；In the lateral surface subscript of dry powder can 2
There is scale to show, cooperation manually-operated gate 5 can control the addition of medicament, it is ensured that drug concentration configuration is accurate.
In order to improve the mixed effect of water and medicament, the spiral shell isometric with venturi 3-3 is equipped in the inner surface of the venturi 3-3
Line groove 3-3a.Preferably, it is 4 for the outer diameter ratio of the entrance 3-1 outer diameters of the venturi mixer 3 and venturi 3-3:3；
Venturi 3-3 internal diameters and the ratio of venturi 3-3 length are 1:5, the ratio of venturi 3-3 outer diameters and venturi 3-3 length is 1:3.
Preferably, the entrance 3-1 outer diameters of venturi mixer 3 are 67mm, and venturi 3-3 outer diameters are 50mm, in venturi 3-3
Diameter is 30mm, and venturi 3-3 length is 150mm, and the depth of thread of the corresponding thread groove 3-3a is 0.5mm, the width of thread
For 2mm, screw pitch 75mm.
Operation principle：High pressure water enters the entrance 3-1 of venturi mixer 3, because of the contraction section 3- of venturi mixer 3
2 be cone, and water sprays to venturi 3-3 from contraction section 3-2 high speeds, and under pressure, the jet velocity of water is very fast, in contraction section
3-2 generates negative pressure with the joints feed pipe 3-5, to which medicament to be drawn into.And the setting of venturi 3-3 internal thread grooves 3-3a
So that flow by thread groove 3-3a when, generate cyclonic action, can be sufficiently mixed with medicament, moreover, even if the flow velocity of water compared with
Low, thread groove 3-3a also can make water reach turbulence state in venturi 3-3, not will produce the phenomenon that medicament lumps.
It is compared under the same conditions to being threaded the feeding device before and after groove, obtains data shown in table 1：
Table 1 is threaded the feeding device correction data before and after groove
By table 1 as it can be seen that under identical upper water condition, often there is the phenomenon that medicament caking in pervious feeding device, needs
It clears up 2-3 times；, there is not caking phenomenon in the feeding device of the utility model, it was demonstrated that medicament mixes fully with water, and discharging is suitable
Freely, it ensure that the effect of microorganism transfer drive.
The embodiments of the present invention are described in detail above, but the content is only the preferable of the utility model
Embodiment should not be considered as limiting the scope of the present invention.It is made according to the scope of application of this utility model equal
Deng variation and improvement etc., should all still belong within the patent covering scope of the utility model.
