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 gather dust and the dust by being collected 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 easily deposited on strainer, will cause filter net jam, when calculating dust catching amount also needs that place is dried
Reason, drying process process can then increase whole man-hour.
Utility model content
The utility model aim is to solve the above problems, and the utility model provides dust catching device, when applying
Dust can be prevented to be blocked in the bottom of pre- trap, and drying process process is just completed during dust catching.
The purpose of this utility model is achieved through the following technical solutions：
Dust catching device, including shell, cylinder and motor, the enclosure is equipped with cavity and is 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 terminal 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 further opened on the side wall of the cylinder multiple parallel to the output terminal axis of motor
Side opening, the enclosure are equipped with multiple heating plates.
In the utility model, during 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 draws 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 fallen 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, so that dust sampling result is more objective and accurate.Start heating plate simultaneously, 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, and the utility model is in dust sampling process
In just complete dust drying process, eliminate convention dust sampling in dust drying process.
Further, the opening of the upper opening of the shell and the cylinder is equipped with a pair of tracks to match each other,
Perpendicular to shaft, track is used to rock when limiting rotary drum plane where the track.Track can prevent sky first
Gas is flowed between the upper opening of shell and the opening of cylinder in shell, and Post Orbit can go out during 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 is overlapped 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 terminal 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
Cylinder is controlled to be rotated by axis of shaft, shaft is parallel to the output terminal axis of motor；Starting motor causes cylinder to turn around the shaft
Dynamic, centrifugal force gets rid of the dust fallen 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 so that dust sampling result is more objective and accurate, at the same start plus
Hot plate heats the space of enclosure, 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, and the utility model is in powder
Just dust drying process is completed in dirt sampling process, eliminates dust drying process in convention dust sampling.
