Description
Technical field
The present invention relates to air detection equipment, and in particular to a kind of device for trapping dust.
Background technology
Dust sampler refers to the portable tools that dust sample is gathered in dust laden air, and it is pre- that it is widely used in disease
The health prison of the departments such as anti-, environmental monitoring, labour protection, safety supervision, military affairs, research and teaching, metallurgy, petrochemical industry, railway, building materials
Survey and evaluate, be exclusively used in determining dust in air mean concentration in production team workplace.In dust sampler, pre- trapping
Device is the separator of dust sampler, for gathering dust and the dust by being collected in pre- trap internal screen enters
Row Correlative data analysis.But the pre- trap in current dust sampler is in the course of the work, the filter screen in pre- trap
The dust trapped is easily deposited on filter screen, will cause filter net jam, when calculating dust catching amount also needs that place is dried
Reason, drying process process can then increase overall man-hour.
The content of the invention
Present invention aims at solving the above problems, the invention provides a kind of device for trapping dust, and it can when applying
Prevent dust to be blocked in the bottom of pre- trap, and drying process process is just completed during dust catching.
The purpose of the present invention is achieved through the following technical solutions：
A kind of device for trapping dust, including shell, cylinder and motor, the enclosure are provided with cavity and only one
Upper opening, outer casing bottom offer multiple air holes, and the cylinder is placed in cavity described in shell and only one opening, outside
The upper opening of shell overlaps with the opening of cylinder, and the bottom of the cylinder is provided with multiple apertures, and cylinder inner wall is furnished with
Filter screen；The motor is fixed in shell internal cavity, and master gear is connected in the output end of motor, and pinion is cased with cylinder, circle
Cylinder is arranged on outer casing inner wall by rotating shaft, and the master gear and pinion are mutually twisted, and motor passes through master gear and pinion
Cylinder is controlled to be rotated by axis of rotating shaft, the shaft parallel is also opened on the output end axis of motor, the side wall of the cylinder
Provided with multiple side openings, the enclosure is provided with multiple heating plates.
In the present invention, during the bottom part down exhausting of pre- trap, the air of the hollow intracavitary of shell flows to lower section by air holes,
After pressure between shell and cylinder reduces, the air in cylinder will flow out cylinder by aperture, finally realize outside shell
Air be evacuated in cylinder, the filter screen of cylinder inner wall is by the adsorbing powder dust in air, eventually through the weight change for calculating filter screen
Draw the dust situation in air.The present invention causes cylinder to rotate around the axis in use, starting motor, and now centrifugal force will fall
Got rid of in the dust of bottom of cylinder to cylinder side wall so that the filter screen of bottom of cylinder is not easily blocked, and the air flux in cylinder will not
Diminish after working long hours, so that dust sampling result is more objective and accurate.Start heating plate simultaneously, to enclosure
Space is heated, and in rotary drum, will be heated into the air in cylinder and dust, air and dust contained humidity
Steam will be evaporated to, steam is then thrown out of cylinder at side opening, and the present invention just completes powder during dust sampling
Dirt drying process, eliminate dust drying process in convention dust sampling.
Further, the opening of the upper opening of the shell and the cylinder is provided with a pair of tracks to match each other,
Perpendicular to rotating shaft, track is used to rock when limiting rotary drum plane where the track.Track can prevent sky first
Gas is flowed into shell between the upper opening of shell and the opening of cylinder, and its Post Orbit can go out during rotary drum
Existing bias.
By using the present invention, following beneficial effect can be produced：The present invention includes shell, cylinder and motor, in shell
Portion is provided with cavity and an only upper opening, and outer casing bottom offers multiple air holes, and cylinder is placed in the hollow intracavitary of shell and only
There is an opening, the upper opening of shell overlaps with the opening of cylinder, and the bottom of cylinder is provided with multiple apertures, and cylinder inner wall is furnished with
Filter screen；Motor is fixed in shell internal cavity, and master gear is connected in the output end of motor, pinion is cased with cylinder, cylinder leads to
Rotating shaft is crossed on outer casing inner wall, master gear and pinion are mutually twisted, and motor controls cylinder by master gear and pinion
Rotated by axis of rotating shaft, shaft parallel is in the output end axis of motor；Start motor cylinder is rotated around the axis, now from
Mental and physical efforts get rid of the dust fallen in bottom of cylinder to cylinder side wall so that the filter screen of bottom of cylinder is not easily blocked, the air in cylinder
Flux will not diminish after working long hours, so that dust sampling result is more objective and accurate, while start heating plate, externally
Space inside shell is heated, and in rotary drum, will be heated into the air in cylinder and dust, air and dust
Contained humidity will be evaporated to steam, and steam is then thrown out of cylinder at side opening, the present invention during dust sampling just
Dust drying process is completed, eliminates dust drying process in convention dust sampling.
