Description
Technical field
The utility model is related to air detection equipment, and in particular to a kind of pre- trap.
Background technology
Dust sampler refers to the portable tools that dust sample is acquired 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
It surveys and evaluates, be exclusively used in measuring dust in air mean concentration in production team workplace.It is pre- to trap in dust sampler
Device is the separator of dust sampler, for acquire dust and by the collected dust of institute in pre- trap internal screen into
Row Correlative data analysis.But the pre- trap in current dust sampler is during the work time, the strainer in pre- trap
The dust trapped is easy to be deposited on strainer, will cause filter net jam, so that the hollow air flux of pre- trap is insufficient, most
Whole dust sampling result is not objective and accurate enough.
Utility model content
The utility model aim is to solve the above problems, and the utility model provides a kind of pre- trap, when applying
Dust can be prevented to be blocked in the bottom of pre- trap, do not interfere with the air flux in pre- trap, dust sampling result also can
It is more objective and accurate.
The purpose of this utility model is achieved through the following technical solutions：
A kind of pre- trap, including shell, cylinder and motor, the enclosure are equipped with cavity and are only opened there are one top
Mouthful, outer casing bottom offers multiple air holes, and the cylinder is placed in cavity described in shell and only there are one opening, the institutes of shell
It states upper opening to overlap with the opening of cylinder, the bottom of the cylinder is equipped with multiple apertures, and cylinder inner wall is furnished with strainer；Institute
It states motor to be fixed in shell internal cavity, master gear is connected on the output end of motor, pinion is cased on cylinder, cylinder is by turning
Axis is mounted on outer casing inner wall, and the master gear and pinion are mutually twisted, and motor controls cylinder by master gear and pinion
It is rotated by axis of shaft, the shaft is parallel to the output end axis of motor.
In the utility model, when the bottom part down exhausting of pre- trap, the air in shell hollow cavity is flowed to by air holes
Lower section, after the pressure between shell and cylinder reduces, the air in cylinder will flow out cylinder by aperture, and finally realizing will be outer
Air outside shell is evacuated in cylinder, and the strainer of cylinder inner wall is by the adsorbing powder dust in air, eventually by the weight for calculating strainer
Variation obtains the dust situation in air.The utility model in use, start motor cylinder is rotated around the axis, at this time from
Mental and physical efforts get rid of the dust for falling in bottom of cylinder to cylinder side wall so that the strainer of bottom of cylinder is not easy to plug, the air in cylinder
Flux will not become smaller after working long hours, to keep dust sampling result more objective and accurate.
Further, the opening of the upper opening of the shell and the cylinder is equipped with a pair of tracks to match each other,
Plane where the track is perpendicular to shaft, and track when limiting rotary drum for that will not shake.Track can prevent sky first
Gas is flowed between the upper opening and the opening of cylinder of shell in shell, and Post Orbit can go out when rotary drum
Existing bias.
By using the utility model, following advantageous effect can be generated：The utility model includes shell, cylinder and electricity
Machine, enclosure is equipped with cavity and only there are one upper opening, outer casing bottom offers multiple air holes, and it is hollow that cylinder is placed in shell
Intracavitary and only there are one opening, the upper opening of shell overlaps with the opening of cylinder, and the bottom of cylinder is equipped with multiple apertures, cylinder
Inner wall is furnished with strainer；Motor is fixed in shell internal cavity, and master gear is connected on the output end of motor, secondary tooth is cased on cylinder
Wheel, cylinder are mounted on by shaft on outer casing inner wall, and master gear and pinion are mutually twisted, and motor passes through master gear and pinion
It controls cylinder to rotate by axis of shaft, shaft is parallel to the output end axis of motor；Start motor and so that cylinder rotates shaft rotation
Dynamic, centrifugal force gets rid of the dust for falling in bottom of cylinder to cylinder side wall at this time so that the strainer of bottom of cylinder is not easy to plug, cylinder
In air flux will not become smaller after working long hours, to keep dust sampling result more objective and accurate.
