Description
Technical field
The utility model is related to air detection equipment, and in particular to low discharge air sampler.
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
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, what pre- trap trapped
Dust easily drops when being measured after the completion of trapping, causes dust sampling result inaccurate.
Utility model content
The utility model aim is to solve the above problems, and the utility model provides low discharge air sampler, should
Used time can prevent trapped dust to be not easy to drop, and dust sampling result is more objective and accurate.
The purpose of this utility model is achieved through the following technical solutions：
Low discharge air sampler, including cylinder, the cylinder is the empty cylinder of upper and lower opening, and cylinder interior is equipped with partition plate,
Cylinder interior is divided into superjacent air space and underlying space by the partition plate, is sampled on the side wall of the superjacent air space of cylinder with one layer
Cotton；Multiple apertures are offered on the partition plate, the upper face of partition plate has one layer of strainer；Further include motor and pedestal, the electricity
Machine is fixed on pedestal, and the output shaft of motor is stretched into below cylinder and is fixed on partition plate bottom surface, fixed on the output shaft
Have a multi-disc blade, the blade for both superjacent air space and underlying space of cylinder to be made to generate pressure difference, the shaft of motor with
The axis collinear of cylinder.
The utility model is in use, open motor, the wind direction of wind is downward caused by blade, due to setting for aperture
Put, can make cylinder underlying space pressure be less than cylinder superjacent air space pressure, make extraneous air from cylinder upper opening into
Enter cylinder, the dust in air will be trapped by sampling cotton afterwards, and strainer can prevent the dust in air from entering below cylinder
Space and then fan is damaged, the shaft of cylinder is conllinear with the shaft of motor in rotation process；Rotary drum can lead to after starting motor
Crossing centrifugal force makes the dust being located in cylinder tightly adsorb in sampling cotton surface and inside.Eventually by the weight for calculating sampling cotton
Amount variation draws the dust situation in air.
Further, the filter opening diameter of the strainer is less than the filter opening diameter of sampling cotton, can be better protected from dust entrance
Cylinder underlying space where fan.
Further, the partition plate is parallel to cylinder bottom surface.
By using the utility model, following advantageous effect can be generated：The utility model includes cylinder, sampling cotton, filter
Net, partition plate, fan, motor and pedestal, cylinder are divided into superjacent air space and underlying space by partition plate, and the output shaft of motor is under cylinder
Side stretches into and is connected on partition plate bottom surface, and sampling cotton is located above space；On the one hand motor is used to drive rotary drum to generate
Centrifugal force makes dust tightly adsorb on sampling cotton surface and inside, under on the other hand being made by the blade being fixed on output shaft
The pressure of side space is less than the pressure of superjacent air space, and in the utility model, motor realizes two effects simultaneously, saves into
This simultaneously simplifies structure.
Description of the drawings
Attached drawing described herein is used for providing further understanding the utility model embodiment, forms the one of the application
Part does not form the restriction to the utility model embodiment.In the accompanying drawings：
Fig. 1 is the structure diagram of the utility model.
Mark and corresponding parts title in attached drawing：1- cylinders, 2- sampling cottons, 4- partition plates, 5- apertures, 6- blades, 8-

Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, with reference to embodiment and attached drawing,
The utility model is described in further detail, and the exemplary embodiment and its explanation of the utility model are only used for explaining this
Utility model is not intended to limit the scope of the present invention.
As shown in Figure 1, low discharge air sampler, including cylinder 1, cylinder 1 is the empty cylinder of upper and lower opening, inside cylinder 1
Equipped with partition plate 4, partition plate 4 will be divided into superjacent air space and underlying space inside cylinder 1, have on the side wall of the superjacent air space of cylinder 1
One layer of sampling cotton 2；Multiple apertures 5 are offered on partition plate 4, the upper face of partition plate 4 has one layer of strainer 11；Further include 8 He of motor
Pedestal 9, motor 8 are fixed on pedestal 9, and the output shaft 10 of motor 8 is stretched into from 1 lower section of cylinder and is fixed on 4 bottom surface of partition plate, defeated
Multi-disc blade 6 is fixed on shaft 10, blade 6 is electric for both superjacent air space and underlying space of cylinder 1 to be made to generate pressure difference
The shaft of machine 8 and the axis collinear of cylinder 1；The filter opening diameter of strainer 11 be less than sampling cotton 2 filter opening diameter, partition plate 4 parallel to
1 bottom surface of cylinder.
Above-described specific embodiment, the purpose of this utility model, technical solution and advantageous effect have been carried out into
One step is described in detail, it should be understood that the foregoing is merely specific embodiment of the present utility model, is not used to limit
Determine the scope of protection of the utility model, within the spirit and principle of the utility model, any modification for being made equally is replaced
It changes, improve, should be included within the scope of protection of this utility model.
