Description
Technical field
The present invention relates to can effectively reduce liquid medicine melting concn fluctuation online medicament-mixing device field, specifically one
Kind is applied to the medicine mixer of the weak flowed fluctuation of sandwich-type of pesticide on-line mixing spraying system.
Background technique
In order to guarantee the accuracy of the required pesticide residue prediction model of essence amount application, in the on-line mixing for improving pesticide and water
It also needs to reduce the mixed liquid concentration unstability as brought by injection flowed fluctuation to the greatest extent while uniformity.Efficiently exist
Line medicine mixer wants carry out liquid medicine that can be instant uniformly to blend, while being also avoided that more current-carrying energy loss.
For the pesticide on-line mixing spraying system pouring-in for direct spray head, single nozzle needs to be equipped with corresponding mixing
Device is to improve liquid medicine uniformity.Under normal circumstances, the proportion of pesticide and water is very low, therefore for solvent (water), molten
The amount of matter (pesticide) is a small amount of.Pesticide on-line mixing spraying system generally uses positive-displacement metering pump directly for medicine or electromagnetism
Valve is indirectly for medicine.For metering pump, small flow is for having that revolving speed is lower when medicine；For solenoid valve indirectly for medicine, in list
It is equally discontinuous for medicine since duty ratio acts in a pulse output period；Therefore in the feed system of pesticide, flowed fluctuation
It is difficult to avoid.Existing liquid medicine on-line mixing device also fails to solve to fluctuate bring mixed liquid concentration unstability for medical abortion amount
Problem.In addition, existing pesticide on-line mixing device is applied to the biggish occasion of current-carrying (water) flow more, often use is such as round
Pipe jet, and the mode for promoting spiral flow to generate promote to mix, however in the practical application of medicine mixer, especially in direct spray head
In pouring-in pesticide on-line mixing spraying system, single nozzle flow very little sometimes, turbulent flow development is not filled under the conditions of small Reynolds number
Point, the effect is unsatisfactory by the way of spiral flow mixing and random wave ambient mixing.
Such as Chinese patent, application number 200910101373.7, denomination of invention: synchronous injection-type medicine mixer for spraying machine,
There is autonomous system supply pesticide to mix with water for the device and similar device, is all made of jet stream and realizes that negative pressure inhales medicine and helical blade
Promote mixing, mixed effect declines with current-carrying (water) flow-reduction, therefore system not can guarantee current-carrying flow it is smaller under the conditions of
On-line mixing uniformity, and medicine mixer do not consider completely pesticide flowed fluctuation to mixing bring negative effect.For another example Chinese
Patent, application number 201610220373.9, denomination of invention: a kind of composite static mixer, the device is by liquid inlet conduit and leaf
Piece welds together, and radially adds auxiliary agent by conduit, promotes to mix by blade scrolling fluid, although radially distributed
Solute injection hole is conducive to improve mixing uniformity, but the device mainly or by helical blade promotes to blend, therefore
A variety of solutes, which carry out mixed uniformly efficiency with solvent, under lower current-carrying (solvent) amount to reduce, which does not consider solute flow
Fluctuation problem.Other static mixing devices, such as Chinese patent 201610918892.2, denomination of invention: static mixer, Yi Jizhong
State's patent 201710832962.7, denomination of invention: static spray mixer, use is all by special static mixing device knot
Structure is arranged in entrance rear, Multiple components substance is realized to mixed mode by force, therefore it is (molten inevitably to will cause biggish current-carrying
Agent) energy loss, which does not consider injection flowed fluctuation problem equally.For another example Chinese patent 201080010750.7, invention
Title: coaxial compact static mixer and its purposes carry out assembling using multiple coaxial mixed class and form tandem type
Static mixing device, divide whole runner to form small flow channels, be mixed by fluid flow separation and converging again, should
Device equally exists that structure is complicated, the larger disadvantage of energy loss, and it is dense to mitigate mixing brought by solute flow fluctuation
Spend instability problem.
Although negative-pressure suction medicine and compressed gas can eliminate flow pulsation for medicine, related invention application is still deposited
It is much limiting, such as it is difficult to ensure that the stabilization of pressure and the accuracy for medicine rate.Such as Chinese patent, application number:
201510079179.9, denomination of invention: medicine bag is concentrated on realizing on medicament-mixing device in the invention and is supplied by a kind of movable medicine mixer
Medicine and conglomerate integration draw medical fluid by negative pressure, although drug delivery device can guarantee that pesticide becomes a mandarin substantially steady, deposit
The efficiency of helical flow generating device also can be with current-carrying (water) flow velocity in the defect that melting concn can not be precisely controlled, the invention
Decline and reduce, mixed effect is insufficient.For another example Chinese patent, application number: 201510083070.2, title: a kind of fixed mixed
Medicine device, the device equally exist it is similar can not overcome injection flowed fluctuation and can not solve current-carrying (water) flow it is lower under the conditions of
Mixing uniformity problem.
Commonly pulse in some fluid damping systems decay technique, as small deflection deformable plates perhaps porous plate or
Cavity type damper, the Fluid pressure being often suitable under medium-high frequency inhibits, not obvious enough to the weakening effect of flowed fluctuation, and
And volume is mostly more huge.Such as Chinese patent, application number 201610115344.6, a kind of patent name: stream of adjustable frequency
Pulsation dampening is measured, the structure is by spring mass system decaying pressure and flow pulsation, and structure is complicated, operating difficulties, it is difficult to
Miniaturization.For another example Chinese patent, application number 201610311919.1, a kind of patent name: full frequency band Research of Pressure Ripple for Hydraulic Systems
Suppressing method, the device cut down high frequency pressure pulsations using elastic wall, cut down low frequency vibration using the series-parallel H-type filter of plug-in type
Dynamic, on the one hand structure is complicated for the system, and still further aspect can not eliminate the biggish flowed fluctuation under low frequency.For another example China is special
Benefit, application number: 201410026386.3, patent name: Broad-frequency pressure-variable pressure pulsation attenuator, the device using accumulator and
Orifice plate avoids pressure fluctuation, when use need to use high pressure gas to accumulator fill can, therefore the system be dfficult to apply to it is small
The fluctuation of injection flow inhibits in the on-line mixing system of flow.
In short, at present online mixed medicine field still lack it is a kind of can efficiently promote pesticide and water it is online it is uniform mix, cut
Medicine flowed fluctuation is reduced, improving liquid medicine mixed liquor, stream concentration is stablized out, is not only suitable under the conditions of current-carrying big flow, and be suitable for carrying
Flow the on-line mixing device under small flow rate.
Summary of the invention
Of the existing technology in order to overcome the problems, such as, the object of the invention provides that a kind of to significantly improve liquid medicine on-line mixing equal
Even property, and injection flowed fluctuation can be weakened and then reduce the medicine mixer of liquid medicine melting concn fluctuation, which can be used for current-carrying
Online mixed medicine under conditions of turbulent flow is underdeveloped, has the advantages that mixed effect is preferable and applicability is wide.
Technical scheme is as follows: a kind of medicine mixer for the weak flowed fluctuation on-line mixing device of sandwich-type,
It is characterized in that: seeping medicine device and circulating type medicine injecting device including medicine mixer outer cylinder, the diffusion-type being arranged in medicine mixer outer cylinder, it is described
