That installs adds liquid bath, is provided with agitator in sedimentation reaction groove, and described agitator includes being located at stirring in described sedimentation reaction groove
Mixing bar, the upper end of puddler is flexibly connected with sedimentation reaction groove and is connected with driving motor by belt, the lower end peace of puddler
Equipped with multiple stirring vanes；
Described puddler is the hollow-core construction with central shaft hole, and its upper end is connected by conduit and the outlet at bottom adding liquid bath
Logical, the bar wall of puddler is provided with multiple liquid outlet；Connect on described conduit and have booster pump.
Further improvement as technique scheme:
The top peripheral of described sedimentation reaction groove is fixed with an annular fixing frame, and the side of described annular fixing frame is by the
Adding liquid bath described in one support fixed installation, opposite side fixedly mounts described driving motor by the second support.
Described stirring vane is symmetrically positioned in the both sides, lower end of puddler, the stirring vane of both sides and the junction of puddler it
Between stagger setting.
The outer end of the stirring vane of puddler both sides is equipped with the stirring end of downward bending, the stirring end of both sides stirring vane
Bottom surface flush.
Of the present utility model have the technical effect that
In this utility model, sedimentation reaction groove is together with adding liquid bath packaging, compact conformation, easy for installation；Add liquid bath direct
Add to agitator, and by booster pump supercharging, in the way of high-pressure injection, potassium nitrate solution is penetrated to waste liquid, carry out
It is sufficiently mixed, improves mixed effect, accelerate response speed, final quickening fluorine and the recovery speed of nitric acid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, sedimentation reaction groove；2, liquid bath is added；3, agitator；31, puddler；32, stirring vane；33, central shaft
Hole；34, liquid outlet；35, stirring end；4, belt；5, motor is driven；6, conduit；7, annular fixing frame；8, the first support；9,

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.
As it is shown in figure 1, the booster-type liquid feeding reaction unit of the fluorine-containing nitric acid recovery and processing system of the present embodiment, including sedimentation
The installation fixed above of reactive tank 1 add liquid bath 2, the bottom liquid inlet mouth of sedimentation reaction groove 1 flows into waste liquid, adds in liquid bath 2 and stores
Potassium nitrate solution；Being provided with agitator 3 in sedimentation reaction groove 1, agitator 3 includes the puddler 31 being located in sedimentation reaction groove 1,
The upper end of puddler 31 is flexibly connected with sedimentation reaction groove 1 and passes through belt 4 and is connected with driving motor 5, the lower end of puddler 31
Multiple stirring vane 32 is installed；Puddler 31 is the hollow-core construction with central shaft hole 33, and conduit 6 and liquid feeding are passed through in its upper end
The outlet at bottom connection of groove 2, the bar wall of puddler 31 is provided with multiple liquid outlet 34.
As it is shown in figure 1, the top peripheral of sedimentation reaction groove 1 is fixed with an annular fixing frame 7, the side of annular fixing frame 7
Adding liquid bath 2 by the first support 8 fixed installation, opposite side drives motor 5 by the second support 9 fixed installation.Annular fixing frame 7
By sedimentation reaction groove 1, add liquid bath 2 and drive motor 5 packaging together, its compact conformation, connection and reasonable arrangement, it is simple to install.
As it is shown in figure 1, for improving mixing effect, stirring vane 32 is symmetrically positioned in the both sides, lower end of puddler 31, both sides
