As further improvement, described current distributing trough top is open, is located on the inwall of aggregate bin; Establish totally enclosed ring-type guiding gutter in the outer wall pressed on ring of the aggregate bin corresponding with current distributing trough, the wall of the aggregate bin between ring-type guiding gutter and current distributing trough is provided with the ring-type pod apertures of perforation; Ring-type guiding gutter is provided with the common water inlet that connects water inlet pipe.
As further improvement, on the inwall of described aggregate bin, be provided with the deflector that at least a slice tilts to install; Deflector has low early and high after angle of inclination in jet water inlet direction, and the installation site of deflector is higher than the position of jet water inlet.
As further improvement, described jet water inlet is more than 2 or 2, and its installation site is evenly arranged in the same level of aggregate bin inwall.
As further improvement, on the water inlet pipe of described jet water inlet and common water inlet, be respectively equipped with ball valve.
As further improvement, described 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 part is taper type.
Compared with prior art, the invention has the beneficial effects as follows:
1, polyacrylamide pulvis enters in NaOH solution tank NaOH and stirs again after the abundant mixing of moisture film, vortex current, has thoroughly eliminated and has cohered phenomenon.
2, the anti-stick knot blender of jet moisture film charging aperture 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.

Fig. 2 is that the anti-stick knot blender of jet moisture film of the present invention is implemented illustration.
Reference numeral in 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.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
In Fig. 1, the anti-stick knot blender of jet moisture film comprises the aggregate bin mixing for powder liquid, the charging aperture 1 that the upper end of this aggregate bin is powder, and 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 part is taper type, inclined design makes the discharging of mixed solution smooth, and discharging opening 9 is less than charging aperture 1, can ensure enough incorporation times.
The inwall of described aggregate bin upper end is provided with the current distributing trough 5 that is used to form ring-type water curtain, current distributing trough 5 tops are open, be located on the inwall of aggregate bin, establish totally enclosed ring-type guiding gutter 3 in the outer wall pressed on ring of the aggregate bin corresponding with current distributing trough 5, the wall of the aggregate bin between ring-type guiding gutter 3 and current distributing trough 5 is provided with the ring-type pod apertures 6 of perforation, and ring-type guiding gutter 3 is provided with the common water inlet 2 that connects water inlet pipe.So just can make water flow into ring-type guiding gutter 3 by common water inlet 2, in ring-type pod apertures 6 flows into current distributing trough 5 equably, in the time of 5 spill-over of current distributing trough, form waterfall moisture film.
The wall at described aggregate bin middle part is provided with at least one and is connected with the jet water inlet 8 of 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 when more than 2 or 2, its installation site is evenly arranged in the same level of aggregate bin inwall.On the inwall of described aggregate bin, be provided with the deflector 7 that at least a slice tilts to install; Deflector 7 has low early and high after angle of inclination in 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, intercept after guiding through deflector 7, form vortex fluid in eddy flow mixed zone 10, 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-stick knot blender of jet moisture film top, ensures that powder does not escape.
