Embodiment Construction

[0021] The present invention is described with reference to the drawings and embodiments.

[0022] As shown in the figure, the composition of this device includes a stirring motor (2) controlled by a computer (1) to drive the comb brush (3) in the flow bin (12) to rotate at a constant speed, and the dust in the bin is conveyed into the powder collection tank (11), and transported to the conveyor belt (9) through the leak hole (13) at the bottom. The motor (12) controlled by the computer (1) drives the driving wheel (10) to rotate at a constant speed, so that the conveyor belt (9) also keeps moving at a constant speed. The computer (1) controls the rotating speed of the conveyor belt (9) so as to realize the control of the concentration of the dust aerosol.

[0023] The negative pressure generator (8) controlled by the computer (1) can make the negative pressure powder inlet pipe (4) attract the dust on the conveyor belt (9) to flow into the special powder spraying and dissolv...

Abstract

The invention provides a generating device of a dust aerosol, which is characterized in that a stirring motor controlled by a computer drives a comb type brush in a flowing barn to uniformly rotate, dust materials in the barn are delivered into a dust collecting groove and are delivered onto a conveyer belt through a leaking hole at a bottom part, and the computer controls a driving wheel to drive the conveyer belt for working so as to control the generated concentration of dust. A negative pressure generator controlled by the computer makes a negative pressure dust entering pipe attract the dust on the conveyer belt to flow into a special dusting dissolving and separating cavity to form the dust aerosol which is delivered into an aerosol detecting experiment cabin. The generating device of the dust aerosol has the function for continually and quantificationally generating the dust aerosol.

Description

technical field [0001] The present invention is applied to fine particles such as nanomaterials and dust aerosols in the detection and calibration of powder science, industrial production, quality control, or inhalation toxicity experimental research in the fields of medical science, labor hygiene, and environmental protection. prospect. Background technique [0002] In the existing technology, there is no special equipment to meet the demand for continuous and quantitative output of dust aerosols when detecting and calibrating fine particles such as nanomaterials and dust aerosols, or conducting inhalation toxicity experiments. Dust can only be input in the test chamber at one time and the air is blown by a fan at the same time. It cannot simulate the continuous distribution of tiny particles such as nanomaterials and dust aerosols in the actual production and life, and scientific testing and calibration cannot be carried out. , nor can it meet the requirements of continuo...
