Description
Technical field
The present invention relates to a kind of multicomponent on-line mixing devices applied to on-line mixing occasion of screw sandwich, specifically
It is that a variety of a small amount of liquid solutes and liquid solvent disposably can be carried out on-line mixing by one kind that ground, which is said, solid simultaneously with mixing
The on-line mixing device of body soluble solute function.
Background technique
There is on-line mixing solute separately to store with solvent, be independently supplied, and blends immediately, concentrates out the feature flowed.In agriculture
Under numerous application scenarios such as the on-line mixing of medicine sprays, the instant blending of lubricating fluid, on-line mixing device is all essential.
Mixing uniformity is the important factor of evaluation of on-line mixing device.In spraying in field online for pesticide, pesticide is (molten
Matter) with online uniform mix of water (solvent) it can preferably meet the effect of spraying prevention and treatment.Under normal conditions, pesticide and water
Proportion is very low, therefore for solvent (water), the amount of pesticide (solute) is a small amount of, therefore is many times difficult to ensure agriculture
Medicine is fully dispersed in water.Meanwhile in order to which the concentration of all promising policy Multiple Pesticides sprays, the collection of various crop pest and disease damage is realized
Middle prevention and treatment needs online medicament-mixing device that can meet the on-line mixing of a variety of a small amount of pesticides and water simultaneously；The dosage form of common pesticides
Including liquid dosage form and pulvis, the online of plurality of liquid pesticide and solid pesticide and water how is realized in a medicament-mixing device
Mixed problem is not yet completed solution.The quality in industrial lubrication field for another example, lubricating oil has a very big impact lubricant effect,
Lubricating oil mainly includes base oil (solvent) and various additives (solute): such as viscosity index improver, pour-point depressant, being resisted
Oxidant, oiliness improver, foam reducing composition etc., some in lube oil additive are liquid components, some are solid components.If can
To change the additive component of lubricating oil immediately according to required lubrication property before lubrication, it can change lubricant parameter, from
And provide preferably lubricant effect.Due to being a small amount of, required mixing dress for various additives ingredient comparative basis oil
It sets and needs higher mixing efficiency, uniform mixing of a variety of solutes in base oil can be met.
The mode that currently used online liquid liquid mixing arrangement mostly uses jet stream and spiral flow to generate realizes that liquid medicine blends.Example
Such as Chinese patent, application number 201010132393.3, denomination of invention: a kind of automatic medicine-mixing device, the device and similar device tool
There is autonomous system supply working solution to mix with water, mixing is promoted using jet stream and the helical static mixing arrangement of postposition, works as current-carrying
When flow is smaller, jet stream inhales medicine and mixing efficiency, the mixing efficiency of screw decline seriously, and system not can guarantee small stream
On-line mixing uniformity under amount, and can only mostly mix single pesticide.Other mixing arrangements, such as Chinese patent, application number
201610220373.9, denomination of invention: liquid inlet conduit and blade are welded on one by a kind of composite static mixer, the device
It rises, radially adds auxiliary agent by conduit, promote to mix by blade scrolling fluid, the device is compared with solutes a variety of under low discharge
It is lower that mixed uniformly efficiency is carried out with solvent, although structure is bad compared with simple mixed effect.For another example Chinese patent
201610918892.2, denomination of invention: static mixer and Chinese patent 201710832962.7, denomination of invention: static state spray
Mixer is penetrated, use is all that special static mixing device structure is arranged in entrance rear, is realized using the mutation of flowing
Mixed mode, therefore inevitably will cause biggish energy loss.For another example Chinese patent 201080010750.7, denomination of invention:
Coaxial compact static mixer and its purposes carry out the static state that assembling forms tandem type using multiple coaxial mixed class
Mixing arrangement divides whole runner to form small flow channels, by fluid flow separation and converges realization again and mixes, the device is same
Sample is in the presence of structure is complicated, the larger disadvantage of energy loss.
Current existing solid-liquid static mixing device mostly uses jet flow negative pressure structure to realize that drawing solid solute enters current-carrying
In, such as Chinese patent, application number 201110261607.1, denomination of invention: a kind of Dust-free solid and liquid static mixing system, the device
Attract solid powder ball to realize blending into current-carrying by jet flow negative pressure mechanism, can be realized solid-liquid mixing in the game theory, but
It is to rely solely on negative pressure to cause solid injection, it is easy to solid be caused to inject the obstruction of point.For another example Chinese patent, application number
201010269703.6, denomination of invention: a kind of more material online injection water plugging and profile controlling method and apparatus of two-phase, it is same in the invention
Attract solid material to be mixed with liquid using jet flow negative pressure mechanism, equally exist obstruction and matches inaccurate problem.
For another example Chinese patent, application number: 201410231851.7, denomination of invention: solid-liquid two-phase proportion mixing arrangement, the device is using negative
Press mechanism carries out the mode that material absorption and motor supply combine and works, which adds motor device, although having
Help avoid blocking and improve precision, but increase the complexity of system, it is difficult to be applied to a small amount of solid of on-line mixing
Solute occasion.
