Description
Technical field
The present invention relates to air detection equipment, and in particular to has the atmospheric sampling equipment of self-cleaning function.
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；And near can only be to pre- trap
Air sampled, the dust in air Density inhomogeneity of most places, therefore the dust of current dust sampler is adopted
Sample result is not accurate enough.
The content of the invention
Present invention aims at solving the above problems, the invention provides the atmospheric sampling equipment with self-cleaning function,
It can prevent trapped dust to be not easy to drop when applying, and can increase air sampling scope so that dust sampling knot
Fruit is more objective and accurate.
The purpose of the present invention is achieved through the following technical solutions：
Atmospheric sampling equipment with self-cleaning function, including pre- trap, the pre- trap is by cylinder and group of motors
Into the empty cylinder that, the cylinder is opening upwards, cylinder interior is provided with dividing plate, the dividing plate by cylinder interior be divided into superjacent air space with
Underlying space, with one layer of sampling cotton in the side wall of the superjacent air space of cylinder；Multiple apertures are offered on the dividing plate, dividing plate
Upper face has one layer of filter screen；Fan is provided with the underlying space of the cylinder, the fan is used for the superjacent air space for making cylinder
Pressure difference is produced with both underlying spaces；Bottom of cylinder in cylinder underlying space offers multiple air vents；Also include
Motor, main frame, fixed arm and roller, the motor are fixed on main frame, and the output shaft of motor is fixed on bottom of cylinder, motor
Rotating shaft and cylinder axis collinear；A circle groove is offered on the outer surface of the cylinder, track is housed in groove, it is described solid
One end of fixed arm is fixed on main frame, and the other end of fixed arm is provided with roller, and the roller is embedded in track；Also include auxiliary-motor
And base, main frame bottom are fixed with main engine bed, the auxiliary-motor is fixed on base top, and the output end of auxiliary-motor is fixed on main frame
Seat bottom, the base bottom are hinged with multiple supporting legs；The rotating shaft of the motor and the shaft parallel of auxiliary-motor and at a distance of 0.8~
1m。
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.After starting motor, main frame, main engine bed and pre- trap are just with the output of auxiliary-motor
End rotates, so as to increase air acquisition scope so that gathered data is more accurate.This can be made by being hinged on the supporting leg of base bottom
Invention is stably placed on ground, and the angle of supporting leg is adjustable at any time.When auxiliary-motor rotating speed is smaller, the angle of supporting leg can
Set smaller；When auxiliary-motor rotating speed is larger, rotates angular momentum and increase therewith, the angle of supporting leg just needs to be arranged to bigger numerical.
Further, it is hinged with support plate on the free end of the supporting leg, the bottom of the support plate is provided with slipmat, support plate and anti-
Skidding can prevent the present invention from sliding on the ground, and the angle that also prevent the supporting leg when motor rotates changes.

Coating can in the environment of dark normal use the present invention.
Further, water tank is additionally provided with the main frame, water tank is connected to water pipe, and being additionally provided with the bottom of cylinder to open
The cover plate closed, the cover plate are used to blocking or opening air vent, and the water proof and dust proof grade of the fan is IP68 levels, the main frame
Water proof and dust proof grade be IP68 levels.After dust, which gathers, terminates and take out sampling cotton and filter screen, the water in water tank is passed through into water
Pipe injects cylinder, and water enters after cylinder blocks air vent using cover plate, opens waterproof fan, and water will be cleaned in cylinder,
It is achieved thereby that self-cleaning function.Cover plate is opened after having cleaned makes water be discharged from air vent.
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, and plane residing for track and machine shaft are mutual
It is perpendicular.
Further, the rotating speed of the auxiliary-motor output end is arranged to 1~5r/min.
By using the present invention, following beneficial effect can be produced：The present invention include cylinder, sampling cotton, filter screen, dividing plate,
Fan, motor, auxiliary-motor, fixed arm, track, roller, main frame, main engine bed and base, cylinder by dividing plate be divided into superjacent air space and
Underlying space, fan are located at underlying space and reduce the pressure of underlying space, and sampling cotton space above, motor is used to drive
Rotary drum with produce centrifugal force make dust tightly adsorb sampling cotton surface and inside, one end of fixed arm be fixed on base
On, other end installation roller, for track on cylinder outer surface, the entirety of fixed arm, roller and track composition can limit cylinder
Rocked in radial directions in rotation process, auxiliary-motor can control main frame rotate and drive cylinder using auxiliary-motor output shaft as
Rotating shaft and rotate, so as to increase air sampling scope, make sampled data more objective and accurate.
