Description
Technical field
The utility model belongs to electronic applications, refers in particular to a kind of droplet group apparatus for measuring quality.
Background technology
High-pressure electrostatic auxiliary liquid atomization technique is the process that liquid crushing becomes charged drop under high-pressure electrostatic participates in.This atomization process that is participated in by high-pressure electrostatic is compared many characteristics that are better than conventional atomizing with other spray patterns.High-pressure electrostatic can reduce surface tension of liquid and atomizing resistance on the one hand, and droplet has same sex electric charge, can be broken into littler droplet under the electric field force effect, and it is even that the diameter Distribution of droplet more becomes.Static has increased the controlled variable in atomizing flow field on the other hand, promptly under the certain situation of parameters such as flow, pressure, nozzle diameter, can play certain regulating and controlling effect to atomizing flow field (as droplet size, atomizing angle, range, droplet running orbit etc.) by changing electric pulse field parameter.Electrostatic atomization has been applied to many aspects such as pesticide spraying, industrial spraying, material preparation, oil inflame, industrial dedusting and desulfurization, particle coalescence and separation at present.Particularly the application aspect industrial dedusting is particularly important.
When research and utilization high-pressure electrostatic atomized liquid, specific charge is unusual important parameters.Specific charge is a carrying capacity and the ratio of material mass.Being the important indicator of weighing the charged effect of droplet, is the principal element that influences atomization of liquid effect.Measuring method commonly used is now measured for the target mesh method.That is: charged droplets forms the loop after touching the wire netting of ground connection, electric charge produces little electric current on wire netting, after this electric current is connected to accurate microampere meter, can measure this current value, measure droplet group's quality and corresponding Measuring Time simultaneously, utilize following formula just can obtain specific charge, A=q/m=It/m; A is a specific charge in the formula, and q is a carrying capacity; M is a droplet group quality; I is a strength of current; T is a Measuring Time.Measure droplet group quality and adopt the graduated cylinder manual operations.Because manual measurement causes error bigger, poor repeatability.In order to overcome this shortcoming, the utility model proposes a kind of droplet group apparatus for measuring quality, head it off.
Summary of the invention
Need manual operations in order to overcome existing measurement droplet group quality, the deficiency that error is big, the utility model provides a kind of droplet group apparatus for measuring quality, and this device can be measured droplet group quality automatically automatically.
The technical scheme that its technical matters that solves the utility model adopts is: the utility model device is made up of the metal utmost point, atomizer, droplet gatherer, wire netting, measuring cup, the resistance utmost point, single-chip microcomputer, it is characterized in that: the resistance utmost point is in measuring cup.
Principle of work of the present utility model is: in nozzle, be subjected to the effect of high-voltage electrostatic field by the droplet of atomizer ejection, thus electric charge on the lotus.When the droplet that has electric charge sprays in the droplet gatherer, run into the wire netting that is installed in the droplet gatherer.Because wire netting is by reometer ground connection, thereby charged droplet forms ground loop by wire netting and reometer.Electric current can be measured.The droplet of being caught by wire netting relies on the effect of gravity to flow down along wire netting, flows in the measuring cup along the droplet collector wall then.
Be fixed with the metal utmost point on the wall of cup of measuring cup, this metal utmost point is made of metal, and resistance is minimum can ignore.Opposite side at the wall of measuring cup is fixed with the resistance utmost point.It is made by uniform resistance wire.After droplet flows into measuring cup, because the aqueous solution that droplet forms is non-pure water, so have good electrical conductivity.The metal utmost point forms the loop by solution.The resistance of solution can be ignored, and then the resistance of the high resistance utmost point is more little more for liquid level.Formed the loop of the resistance utmost point on a metal utmost point, liquid level, the liquid level.Because the volume of measuring cup is fixed, the volume of solution can reflect by the height of liquid level.The high more volume of liquid level is big more.That is to say that the volume of the more little solution of resistance electrode resistance is big more on the liquid level.Because the proportion of solution is known.Thereby its quality as can be known.
With metal utmost point ground connection.The resistance utmost point links to each other by the same power supply of divider resistance, draws a lead-in wire from the resistance utmost point simultaneously and links to each other with the analog to digital conversion integrated package.The voltage signal that is about to the resistance utmost point is transformed to digital quantity through analog to digital conversion with analog quantity.Be sent to single-chip microcomputer through the signal after the analog to digital conversion.Single-chip microcomputer can calculate droplet group quality according to the calibration information that prestores.
The beneficial effects of the utility model are, can carry out droplet group mass measurement automatically, reduce because the error that manually-operated brings.It is mainly used in high-pressure electrostatic auxiliary liquid atomizing field.
