Abstract
The invention provides a rotating disc type dust aerosol generating device characterized in that an agitating motor is controlled by a computer to drive an agitating blade in a flowing chamber to rotate, and dust in the flowing chamber is uniformly agitated and conveyed to a pit which is arranged on a rotating disc below a drain hole on the bottom of the flowing chamber and specially used for carrying dust; and dust stored in the pit on the rotating disc is absorbed into a dust spray dissolution cavity by a negative pressure generator which is controlled by the computer through a negative pressure dust suction pipe, and dust aerosol is formed and then conveyed into an aerosol detection laboratory chamber to be detected and experimented. When the agitating motor controlled by the computer rotates at different rotating speeds and uses rotating discs of different pit widths, the quantity of dust conveyed to the negative pressure dust suction pipe is different, and the concentration of dust aerosol formed by dust flowing in the dust spray dissolution cavity is also different. Therefore, dust aerosol of stable concentration can be continuously, accurately and quantitatively generated by selecting a rotating disc of proper pit width and proper rotating disc rotating speed and remaining unchanged.
Description
Technical field
The sustainable accurate control of the present invention produces quantitative dust aerosol and is used to provide to scientific research field uses such as the detection of superfine dust size, Atmospheric particulates research and human breathing disease poison.Can be applied to also that fine particulates such as nano material detect in powder science, industrial production, quality control, field such as demarcation or medical science, labour health, environmental protection carries out aspects such as toxicity on inhalation experimental study and has a wide range of applications.
Background technology
In the prior art, fine particulates such as nano material and dust aerosol are detected, demarcate or do not have when carrying out the toxicity on inhalation experimental study special equipment to satisfy to continue the quantitatively aerocolloidal demand of output dust.Can only in the test experience cabin, import dust once and use the blower fan blow air simultaneously, can not simulate in the actual production life finely ground particles such as nano material and dust aerosol in the lasting distribution situation in space, also just can not carry out the detection and the demarcation of science, more can not produce requirement when continuing high concentration fine particle dust aerosol and satisfying the toxicity on inhalation experimental study.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide a kind of rotating disc type dust aerosol generating device.This device comprises that the stirring piece that is driven in the storehouse of flowing by stirring motor of computer control rotates, and inner dust is stirred and is transported in the hole groove of special carrying dust on the rotating disc of bottom small opening bottom in the storehouse of flowing.Computer-controlled negative pressure generator is drawn into the dust that carries in the hole groove on the rotating disc by the negative pressure powder absorbing pipe and dusts moltenly in the chamber and form the dust aerosol, is transported in the aerosol test experience cabin again and detects and test.When computer-controlled rotary tray motor by different rotating speeds rotation and when selecting the rotating disc of different holes well width for use, its Dust Capacity that is transported to the negative pressure powder absorbing pipe is just different, flows to dust that molten to form the aerocolloidal concentration of dust in the chamber also just different.So select the rotating disc and the suitable rotating disc rotating speed of suitable hole well width and the dust aerosol of the generation steady concentration that just can continue accurate quantification of remaining unchanged.
Rotating disc type dust aerosol generating device has satisfied and has existingly carried out fine particulates such as nano material and dust aerosol are detected, demarcate or do not have when carrying out the toxicity on inhalation experimental study special equipment to satisfy to continue the aerocolloidal demand of a large amount of high concentrations output dust.Solved in the simulation actual production life finely ground particles such as nano material and dust aerosol in the lasting distribution situation in space, carry out the detection and the demarcation of science whenever and wherever possible, also can produce the technical barrier that requires when lasting high concentration fine particle dust aerosol satisfies the toxicity on inhalation experimental study.
For achieving the above object, technical scheme of the present invention provides this device and comprises that the stirring piece that is driven in the storehouse of flowing by stirring motor of computer control rotates, and inner dust is stirred and is transported in the hole groove of special carrying dust on the rotating disc of bottom small opening bottom in the storehouse of flowing.Computer-controlled negative pressure generator is drawn into the dust that carries in the hole groove on the rotating disc by the negative pressure powder absorbing pipe and dusts moltenly in the chamber and form the dust aerosol, is transported in the aerosol test experience cabin again and detects and test.When computer-controlled rotary tray motor by different rotating speeds rotation and when selecting the rotating disc of different holes well width for use, its Dust Capacity that is transported to the negative pressure powder absorbing pipe is just different, flows to dust that molten to form the aerocolloidal concentration of dust in the chamber also just different.So select the rotating disc and the suitable rotating disc rotating speed of suitable hole well width and the dust aerosol of the generation steady concentration that just can continue accurate quantification of remaining unchanged.
Effect of the present invention is: have the dust aerosol that can continue, stablize, accurately control generation height variable concentrations.
