Description

Dust conveyor and dust generating device

Technical Field

The utility model relates to a dust conveyor especially relates to a dust conveyer and dust generating device.

Background

Dust particles are typically less than 500 microns in diameter, with suspended particles less than 10 microns in diameter, i.e., Fine Particulate Matter (PM 2.5) less than 2.5 microns in diameter, being considered harmful to the human body, penetrating the alveoli through to the blood. The dust tester measures the concentration of Inhalable Particles (PM 10), the concentration of PM2.5 and the concentration of respiratory dust, total dust concentration, dust mass concentration in the air.

The service life detection of the dust tester needs to keep the dust tester in a constant dust concentration and constant humidity environment, and the dust tester needs to measure in the constant dust concentration and constant humidity environment for a long time. The dust is required to be kept in a dry state before being conveyed to the detection environment, so that the humidity of the dust in the detection environment can be conveniently controlled in the subsequent dust mixing process. When simulating the detection environment of the dust tester, dust or dust conveyed by the dust conveying device is generally blown into the detection environment by the dust generating device in a manner of blowing the dust or dust through an air flow. Wind speed and dust delivery may control the dust concentration of the test environment, but may not control the humidity of the dust in the test environment. In general, the variation of humidity is also an important factor affecting the detection of the service life of the dust tester. If the humidity of the dust cannot be controlled at the time of dust conveyance, the humidity of the dust blown to the detection environment by the wind is also difficult to control.

Both the dust generating apparatus and the dust transporting apparatus of the prior art cannot maintain the humidity of the dust constant during the transportation of the dust. In particular, in the case of long-term detection, the humidity of dust may change with the passage of time. The humidity of the dust conveyed initially and the humidity of the dust conveyed after a long time of standing are generally greatly different, which results in that the humidity of the dust in the detection environment is difficult to control.
