As further improvement, said current distributing trough top is open, is located on the inwall of aggregate bin; With the outer wall of the corresponding aggregate bin of current distributing trough on ring establish totally enclosed ring-type guiding gutter, the wall of the aggregate bin between ring-type guiding gutter and the current distributing trough is provided with the ring-type pod apertures of perforation; The ring-type guiding gutter is provided with the common water inlet that connects water inlet pipe.
As further improvement, on the inwall of said aggregate bin, be provided with the deflector that a slice inclination is at least installed; Deflector has low early and high after angle of inclination on jet water inlet direction, and the installation site of deflector is higher than the position of jet water inlet.
As further improvement, said jet water inlet is more than 2 or 2, and its installation site evenly is arranged on the same horizontal plane of aggregate bin inwall.
As further improvement, be respectively equipped with ball valve on the water inlet pipe of said jet water inlet and common water inlet.
As further improvement, said aggregate bin has three stage structure, and its two ends are cylindrical tube, and the cylindrical tube internal diameter of upper end is greater than the cylindrical tube internal diameter of lower end, and middle transition partly is taper type.
Compared with prior art, the invention has the beneficial effects as follows:
1, gets into stirring in the NaOH solution tank NaOH again after the abundant mixing of polyacrylamide pulvis through moisture film, vortex current, thoroughly eliminated and cohered phenomenon.
2, the anti-blender charging aperture that coheres of jet moisture film produces negative pressure, and powder does not escape, and has improved the utilization rate of polyacrylamide, reduces material consumption.
3, improved the stability of water treatment technology.

Reference numeral among the figure is: 1 charging aperture; 2 common water inlets; 3 ring-type guiding gutters; 4 ball valves; 5 current distributing troughs; 6 ring-type pod apertures; 7 deflectors; 8 jet water inlets; 9 discharging openings; 10 eddy flow mixed zones; 11 conveying worms; 12 NaOH solution tank NaOHs.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
Among Fig. 1, the anti-blender that coheres of jet moisture film comprises the aggregate bin that is used for the mixing of powder liquid, and the upper end of this aggregate bin is the charging aperture 1 of powder, and the lower end is the discharging opening 9 of powder liquid mixture.Aggregate bin has three stage structure, and its two ends are cylindrical tube, and the cylindrical tube internal diameter of upper end is greater than the cylindrical tube internal diameter of lower end; Middle transition partly is taper type; Inclined design makes the discharging of mixed solution smooth, and discharging opening 9 can guarantee enough incorporation times less than charging aperture 1.
The inwall of said aggregate bin upper end is provided with the current distributing trough 5 that is used to form the ring-type water curtain; Current distributing trough 5 tops are open; Be located on the inwall of aggregate bin; With the outer wall of current distributing trough 5 corresponding aggregate bins on ring establish totally enclosed ring-type guiding gutter 3, the wall of the aggregate bin between ring-type guiding gutter 3 and the current distributing trough 5 is provided with the ring-type pod apertures 6 of perforation, ring-type guiding gutter 3 is provided with the common water inlet 2 of connection water inlet pipe.So just can make water flow into ring-type guiding gutter 3, in ring-type pod apertures 6 flows into current distributing trough 5 equably, when 5 spill-overs of current distributing trough, form the waterfall moisture film by common water inlet 2.
The wall at said aggregate bin middle part is provided with the jet water inlet 8 that at least one is connected with water inlet pipe; The direction of jet water inlet 8 is consistent with the tangential direction of aggregate bin inwall; When jet water inlet 8 is 2 or 2 when above, its installation site evenly is arranged on the same horizontal plane of aggregate bin inwall.On the inwall of said aggregate bin, be provided with the deflector 7 that a slice inclination is at least installed; Deflector 7 has low early and high after angle of inclination on jet water inlet 8 directions, and the installation site of deflector 7 is higher than the position of jet water inlet 8.Flow into when a large amount of water is tangent line by jet water inlet 8, after deflector 7 intercepted guiding, 10 formed the vortex fluid in the eddy flow mixed zone, and the vortex fluid covers discharging opening 9, and current are pressed to discharging opening 9.Under the drive of current, negative pressuren zone is formed at the anti-blender top of cohering of jet moisture film, guarantees that powder does not escape.
Be respectively equipped with ball valve 4 on the water inlet pipe of said jet water inlet 8 and common water inlet 2, be used for controlling the discharge that gets into jet water inlet 8 and common water inlet 2.
During use, an amount of water by common water inlet 2 flow into ring-type guiding gutter 3, in ring-type pod apertures 6 flows into current distributing trough 5 equably, when current distributing trough 5 in during the water spill-over, formation waterfall moisture film.
A large amount of water is the anti-mixer inner walls tangential direction of cohering of jet moisture film by jet water inlet 8 and flows into, and forms the vortex fluid, and after deflector 7 intercepted guiding, the vortex fluid covered discharging opening 9, and current are pressed to discharging opening 9.Under the drive of current; Negative pressuren zone is formed at the anti-blender top of cohering of jet moisture film; This moment is after the polyacrylamide pulvis gets into charging aperture 1 via conveying worm 11; Promptly brought into and mix fully in the vortex and stir, taken out of the NaOH solution tank NaOH 12 that gets into next step by current from discharging opening 9 at last, do further slaking dissolving by following sluicing film.
Certainly, this jet moisture film prevents that cohering blender is not limited in polypropylene acid amides pulvis, also can mix the flocculant in other water treatments, even can also be applied to other solvents of required mixing in the productive life.In addition, the jet moisture film is anti-to be cohered blender and is not limited in top and is cylindrical tube, and lower middle portion is a taper type, and lower end discharging opening 9 is the such shape of small cylindrical, and each several part can be designed to the shape of various rules and non-rule.Such conversion all drops within protection scope of the present invention.
