Description
Technical field
The present invention relates to air detection equipment, and in particular to a kind of air quality inspection acquisition system.
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, what pre- trap trapped
Dust easily drops when being measured after the completion of trapping, causes dust sampling result inaccurate.
The content of the invention
Present invention aims at solving the above problems, the invention provides a kind of air quality inspection acquisition system, when it is applied
Trapped dust can be prevented to be not easy to drop, dust sampling result is more objective and accurate.
The purpose of the present invention is achieved through the following technical solutions：
A kind of air quality inspection acquisition system, including cylinder, the cylinder be opening upwards empty cylinder, cylinder interior be provided with every
Cylinder interior is divided into superjacent air space and underlying space, adopted in the side wall of the superjacent air space of cylinder with one layer by plate, the dividing plate
Sample cotton；Multiple apertures are offered on the dividing plate, the upper face of dividing plate has one layer of filter screen；Set in the underlying space of the cylinder
There is fan, the fan is used to make both superjacent air space and underlying space of cylinder produce pressure difference；Positioned at cylinder underlying space
In bottom of cylinder offer multiple air vents；Also include motor, base, fixed arm and roller, the motor is fixed on base
On, the output shaft of motor is fixed on bottom of cylinder, the rotating shaft of motor and the axis collinear of cylinder；On the outer surface of the cylinder
A circle groove is offered, track is housed in groove, one end of the fixed arm is fixed on base, is set on the other end of fixed arm
There is roller, the roller is embedded in track.
For the present invention in use, open fan, the wind direction of fan is downward, due to the setting of aperture and air vent,
The pressure of cylinder underlying space is less than the pressure of cylinder superjacent air space, extraneous air is entered cylinder from cylinder upper opening,
The dust in air will be sampled cotton and be trapped afterwards, filter screen can prevent dust in air enter cylinder underlying space and then
Damage fan；Rotary drum can be such that the dust in cylinder tightly adsorbs in sampling cotton table by centrifugal force after starting motor
Face and inside, fixed arm, roller and being used cooperatively for track are to be in limit cylinder in rotation process in radial directions
Rock so that cylinder can keep the rotating shaft of cylinder not deviate by machine shaft when rotating.Eventually through the weight for calculating sampling cotton
Amount change draws the dust situation in air.
Further, the filter opening diameter of the filter screen is less than the filter opening diameter of sampling cotton, can be better protected from dust entrance
Cylinder underlying space where fan.
Further, the dividing plate is parallel to cylinder bottom surface.
Further, plane is parallel with plane where dividing plate where the track.
By using the present invention, following beneficial effect can be produced：The present invention include cylinder, sampling cotton, filter screen, dividing plate,
Fan, motor, base, fixed arm, track and roller, cylinder is divided into superjacent air space and underlying space by dividing plate, under fan is located at
Side space and the pressure for reducing underlying space, sampling cotton space above, motor are used to drive rotary drum to produce centrifugation
Power make dust tightly adsorb sampling cotton surface and inside, one end of fixed arm be fixed on base, the other end installation roller, rail
On cylinder outer surface, the entirety of fixed arm, roller and track composition can limit cylinder and be in rotation process radially in road
Rocked on direction.
