Technical field
The utility model can accurately produce dust quantity, controls the granularity of dust composition, regulate the different-grain diameter dust concentration, can realize automatic control simultaneously; The utility model can be dust concentration testing research, regularity of dust and migration rule research, different-grain diameter dust settling rule and miner's pneumoconiosis pathological study quantitatively continuous dust source is provided, and belongs to the scientific experiment apparatus.
Background technology
The working faces such as the coal mining under coal mine, explosion tend to produce a large amount of dust, these dust have a strong impact on mine safety in production, harm the workman healthy.Therefore for reducing dust concentration, reduce the impact of various dust on mine production, necessary research regularity of dust, migration rule and settlement law.Dust size is less, endangers larger.So must understand the distribution situation of different-grain diameter dust, according to distribution characteristics and the character thereof of different-grain diameter dust, selecting properly dedusting and dust-removing method, to reduce the harm of dust, carry out Labor Protection.The China's coal-mine dust size mainly is divided into 4 kinds of grades:<2 μ m; >=2～5 μ m;>5～10 μ m;>10 μ m, wherein the dust of particle diameter<5 μ m is called respirable dust, larger to the healthy harm of miner.
In the prior art, test full dirt or respirable dust concentration, during the various rule of research dust, lack the dust source that Special Equipment provides continuously, quantity is controlled, dust size is variable.While analyzing mine dust concentration and rule thereof, can only arrive mining face under mine and carry out dust sampling, to dust test and research work, bring inconvenience.And can not study the dust distribution lasting at lane space and motion conditions by dust sampling, and also just can not obtain reasonably controlling dust collecting method, meet the needs of pneumoconiosis pathological study but more can not produce respirable dust continuous, high concentration.
Summary of the invention
For overcoming above-mentioned technical deficiency, the utility model provide a kind of simple in structure, be easy to carry, applied range, easy to operate, control flexible, safe, be applicable to the funnel suction nozzle type dust generator that the laboratory clean environment is used.
The scheme that the utility model technical solution problem adopts is: a kind of funnel suction nozzle type dust generator is comprised of stirring motor, cabinet, puddler, dust batch meter, suction nozzle, rotating disk, negative tube, dust outlet, stepper motor, depression generator, microcomputer, remote controller, fault sensor, magnetic valve, stepper motor driver, monitoring sensor.It is characterized in that, stirring motor, dust batch meter are fixedly mounted on cabinet internal upper part dividing plate, and puddler is fixedly connected with the stirring motor output shaft; Rotating disk is fixedly connected on the stepper motor output shaft; Monitoring sensor is positioned at the suction nozzle oblique upper, and is fixed on cabinet; Suction nozzle is positioned at rotating disk top and is fixed on the cabinet intermediate membrane, suction nozzle by negative tube be fixed on cabinet in depression generator on lower partition be communicated with; Stepper motor is controlled and is fixed on by stepper motor driver in cabinet on intermediate membrane; Microcomputer and stepper motor driver are by connection, and the two is fixed on the cabinet bottom simultaneously, and the cabinet bottom in microcomputer left side is equipped with fault sensor; Magnetic valve is arranged in source of the gas and depression generator connecting line; Microcomputer can carry out controlled in wireless by remote controller.Be characterized in providing the multiple quantity dust source that accurately controlled, continuous, dust size changes.This generator comprises four groups of dust feeding devices by microcomputer control work, and every group of device all is comprised of a stirring motor, a puddler, a dust batch meter and a rotating disk.The dust that puddler stirs in funnel makes its Uniform Flow, and when rotating disk rotates under stepper motor drives, dust is wire from the funnel bottom outlet and flow into rotating disk.The suction nozzle that microcomputer-controlled depression generator connects by negative tube is drawn into depression generator die cavity inside to dust, fully mix rear ejection with air, for research contents such as dust concentration test analysis and regularity of dust, migration rule and settlement laws.
Put into four kinds of dust that particle diameter is different in four funnels of dust feeding device, the rotating disk of dust feeding device is respectively by four stepper motor drive.Four groups of feeding devices can be worked simultaneously, and also can every group work independently, thereby realize that the dust of four kinds of particle diameters can exist simultaneously, but also individualism, for four kinds of regularity of dust of research.
The stepper motor speed difference that microcomputer is controlled by stepper motor driver, rotary speed will be different, and the dust quantity sucked by suction nozzle is just different, just different in the airborne dust concentration in generator exports place.Therefore, select different rotating disk stepper motor speeds and nozzle structure parameter, will obtain different dust concentrations, thereby realize that dust supplies with continuously, for research different dusts concentration provides quantity controlled dust source to mine production and personnel's harm.
the beneficial effects of the utility model are
This funnel suction nozzle type dust generator can realize four kinds of particle diameter dust simultaneously or form separately continuously dust source, and four kinds of particle diameter dust quantity can accurately control, and easily realize four kinds of particle diameter dust concentrations are accurately controlled; Be convenient to study the regularity of distribution and the settlement law of four kinds of dust simultaneously.
