Description
Technical field
The utility model relates to a kind of static mixer, relates in particular to a kind of helical static mixer for the high-viscosity material mixing.
Background technology
Static mixer is that all kinds of fixing elements are installed in a kind of utilization in pipeline, thereby the flow regime of utilizing these elements to change the flowing pipe inner fluid reaches a kind of blender that liquid mixes purpose, and the static mixer of this no-rotary part and channelization characteristics is used obtaining aspect commercial Application more and more widely with its novel, efficient and energy-conservation superiority.
At present on the domestic and international market successful release multiple static mixer, be widely applied industrial, wherein representative static mixer mainly contains following several: Suhl scholar (Sulzer) SMV type, toray Hi type and the Ross-ISG type of the Kai Nisi of the U.S. (Kenics) type, Switzerland.Due to the internal mixer architectural difference of these kinds, the mixing principle of all kinds static mixer is different, and the mixed characteristic difference is larger, and then mixed effect is also different.Aspect mixed effect in reasonable static mixer take the Suhl scholar's of Switzerland S-X type static mixer as representative, the primary structure of the static mixer of this brand is with the mutual electric welding of blade and linear array, 45 degree that oppositely intersect are rear in linear array, interlaced one-tenth 90 degree in two groups of blades, after high-viscosity material enters the S-X static mixer, and after the cutting repeatedly of blade, reach the effect of mixing.But the S-X static mixer causes the PVAc pump discharge pressure of blender leading portion to increase because flow resistance is excessive, damages the situation of PVAc pump, also easily result in blockage simultaneously, because S-X static mixer internal structure is too complicated, in use, cleaning frequency is short, troublesome poeration.
The utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, and a kind of helical static mixer is provided, and when solving present technology medium-high viscosity mixing of materials, flow resistance Da Yi stops up, the problem that mixing efficiency is low.

Further, the draw ratio of described left-handed blade and dextrorotation blade be 1:1 to 2.1:1, formulate according to the windup-degree of helical blade, guarantee the structural strength of monomer helical blade, adjust the size of flow resistance.
Further, described left-handed blade is 30 ° ~ 90 ° at the circumferential stagger angle with dextrorotation blade junction.The staggered certain angle of adjacent left-handed blade and dextrorotation blade can further be cut apart and converge by convection cell, promotes the mixing of fluid.Different stagger angles is fit to the mixing of inhomogeneity material, and stagger angle is decided with the working condition requirement of reality.
Further, alignment pin is adopted in the junction of described left-handed blade and dextrorotation blade, is fixed with spot welding or the mode that is threaded, has increased greatly the bonding strength between helical blade, guarantee not fracture under the impact of fluid again of junction, increase the service life of blender.
Further, one end of the vane group that described left-handed blade and dextrorotation blade form is connected with the cleaning suspension ring, vane group integral body can be pulled out from the blender shell, clean, assembly and disassembly is convenient, and can clean up any dead angle of vane group, prevent residual flow-induced corrosion helical blade.
Further, an end of described shell is equipped with in order to the installation locating slot that the blade string is fixed, and facilitates the installation of helical blade set, prevents that helical blade set from forwarding living frictional dissipation in the housing inward turning.
Compared with prior art, the utility model advantage is:
Helical static mixer described in the utility model overcomes the deficiencies in the prior art, greatly reduced flow resistance, be difficult for stopping up when mixing high-viscosity material, guaranteed simultaneously the effect of mixing, one independently blade unit material is repeatedly cut, adopted the form of multistage blade unit in the blender sleeve pipe, cutting apart and converging of material is effective, mixing efficiency is high, and energy efficient greatly; The fluid treatment amount is large, and dependable performance in the situation that mass flow is larger, all can realizes continuously, mix fast and efficiently, adopts different helical blade structures for the requirement of different material self-characteristics and degree of mixing, and applicability is strong; And simple in structure, easily assembling, easily manufactured, save production cost, move simple and reliablely, be convenient to clean.
