Description
Technical field
The present invention relates to send out dirt device, a kind of ultrasonic vibratory string micronic dust adding set.
Background technology
Air pollution problems inherent has become the main cities problem of harm human health, dedusting is then to control the effective ways of particle contamination in air, research dust arrester has directiveness to act on for improving urban air-quality, and what the quality of efficiency of dust collection was mainly determined by the dustiness of gas in system inlets.
Therefore, it is possible to solid particle, dust are dissipated in air by device effect according to dissipating requirement, allow it constitute the quantification dust generating device of dispersion in additional space has the effect of key for study of various dust pelletizing system.
All there is at present both at home and abroad a different dirt device (such as disc type, spiral, piston type and mechanical-vibration type) of sending out, but the restriction of all suffered use occasion of this kind of device, and the uniformity coefficient of the powder amount size of unit interval is difficult to meet requirement of experiment.
Summary of the invention
The present invention is to solve that existing dirt device exists the problem that powder amount uniformity coefficient is difficult to meet requirement of experiment, it is provided that a kind of ultrasonic vibratory string micronic dust adding set.
nullThe present invention adopts the following technical scheme that realization: a kind of ultrasonic vibratory string micronic dust adding set，Including dispersion cylinder，It is provided with in dispersion tube body and is connected and horizontally disposed playpipe with its right wall，And the left side of playpipe is cone structure，The right side of playpipe is provided with nozzle，The compressor communicated therewith it is provided with on nozzle，It is provided with primary air air inlet pipe in the dispersion cylinder left wall of playpipe left，It is provided with between primary air air inlet pipe and playpipe and the baffle plate disperseing cylinder upper wall to be connected and move left and right，Dispersion cylinder is provided above the dirt cup body connected with playpipe，It is provided with, in sending out dirt cup body, the vibrating diaphragm having centre bore，And connection has the centre bore cleansing pin moved up and down on a dirt cup body，The ash discharging pipe being positioned at below centre bore it is provided with on vibrating diaphragm，It is disposed with from bottom to up on the upside of vibrating diaphragm and is positioned at the amplitude rod sending out dirt cup body、Transducer、Supersonic generator.
During operation, start supersonic generator, transducer supersonic vibration is converted to the mechanical vibration of amplitude rod, and then drives the mechanical vibration of vibrating diaphragm to make dust vibrate, and disperseed by the ash discharging pipe whereabouts entrance playpipe below centre bore；Meanwhile, the high pressure draught provided by compressor, the dust in entrance playpipe is made to spray, impinge upon the enterprising step of baffle plate to disperse, finally along with primary air air inlet pipe enter together experimental system or contain dust container in, overcome existing dirt device and there is the problem that powder amount uniformity coefficient is difficult to meet requirement of experiment.
Present configuration is reasonable in design reliably, can the dust that fully dissipates of continuous and quantitative transmission, it is particularly suitable for laboratory to use, and be more easy to reach the homodisperse requirement of fine solid particle, the good dispersion of dust, particularly when flow is less than 200L/min, powder amount is smaller than 1g/min, dust granules is less than 1.5 microns, has simple in construction, advantage easily fabricated and easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1-disperses cylinder, 2-playpipe, 3-nozzle, 4-compressor, 5-primary air air inlet pipe, 6-baffle plate, and 7-sends out dirt cup body, 8-vibrating diaphragm, 9-centre bore cleansing pin, 10-ash discharging pipe, 11-amplitude rod, 12-transducer, 13-supersonic generator.
Detailed description of the invention
nullA kind of ultrasonic vibratory string micronic dust adding set，Including dispersion cylinder 1，It is provided with in dispersion cylinder 1 and is connected and horizontally disposed playpipe 2 with its right wall，And the left side of playpipe 2 is cone structure，The right side of playpipe 2 is provided with nozzle 3，The compressor 4 communicated therewith it is provided with on nozzle 3，It is provided with primary air air inlet pipe 5 in dispersion cylinder 1 left wall of playpipe 2 left，The baffle plate 6 being provided with between primary air air inlet pipe 5 with playpipe 2 and disperse cylinder 1 upper wall to be connected and move left and right，Dispersion cylinder 1 is provided above the dirt cup body 7 connected with playpipe 2，It is provided with, in sending out dirt cup body 7, the vibrating diaphragm 8 having centre bore，And connection has the centre bore cleansing pin 9 moved up and down on a dirt cup body 7，The ash discharging pipe 10 being positioned at below centre bore it is provided with on vibrating diaphragm 8，It is disposed with from bottom to up on the upside of vibrating diaphragm 8 and is positioned at the amplitude rod 11 sending out dirt cup body 7、Transducer 12、Supersonic generator 13.
In specific implementation process, 36V alternating current can be changed into unidirectional current and carry out voltage stabilizing and be output as 12V, recycling multivibrator, frequency change is controlled by changing the discharge and recharge time, last by power amplifier, pulse signal inputed to supersonic generator and compressor the most again, supersonic generator realizes the control to powder amount, and compressor realizes sending out dirt degree of scatter and the control of air humidity；Baffle plate 6 is 5-10mm with the distance of playpipe 2 front end face, dispersion effect is preferable, grain graininess is respectively less than 1.5 microns, when apart from excessive, then gas shock is too small, and dust cannot be disperseed, when apart from too small, easily causing partial reflux, turn back flow forward with primary air the most again, the energy loss caused is bigger；Centre bore cleansing pin is for regulate center hole size.
