Description
Technical field
The utility model is related to sample devices field more particularly to a kind of dust sampling meters.
Background technology
With the propulsion of process of industrialization, dust pollution is more serious.Dust pollution directly threatens the life of people, especially
It, which is in the environment of dust pollution, can cause the diseases such as a variety of angiocarpy, respiratory tract.Influence of the dust pollution for old man, child
Maximum, and easily to grow germ virus totally unfavorable to health for excessive dust, is also had for skin health greatly
Harm.Dust sampling meter is widely used in disease prevention, environmental monitoring, labour protection, safety supervision, military affairs, research and teaching, smelting
The monitoring of hygiene and evaluation of the departments such as gold, petrochemical industry, railway, building materials are exclusively used in measuring air in production team workplace
Middle mean dust concentration.
Existing dust sampling meter extracts the air in filter core using diaphragm pump, dust is rested on the film of outside, taken
Sampling head is removed after sample, filter membrane is taken away detection.When needing to be sampled at times, then constantly dismounting sampling is needed
Head carries out replacement filter membrane.Existing filter membrane clip is spiral mouth, and the more slow of filter membrane progress is dismantled in installation, influences sampling efficiency.
After using abrasion throughout the year, screw socket is difficult that complete correspond to is coincide, and makes troubles to filter membrane is replaced when sampling, while also virtually increases
The time of filter membrane exposure in detect environment, influence sampling precision.
Utility model content
The utility model discloses a kind of dust sampling meter, changes kuppe in the prior art and filter membrane clamping device spiral shell
The connection mode of connection is revolved, one end is reached convenient for separated purpose, solved by retention mechanism by rotation axis, the other end
The prior art replaces the problem of filter membrane is cumbersome.
A kind of dust sampling meter, including shell and sequentially connected motor, aspiration pump, flowmeter and sampling head, wherein,
Motor, aspiration pump and flowmeter are fixed on enclosure, and sampling head is fixed on the shell with horizontal boom state, the sampling head
For cylindrical shape, including pedestal, web plate, filter membrane clamping device, retention mechanism and kuppe, the pedestal is fixed on the shell, institute
It states kuppe, filter membrane clamping device and pedestal and passes through horizontal and eccentric setting rotation axis connection, the filter membrane clamping device position
Between kuppe and pedestal, for the kuppe with rotation axis to be slidably connected, the filter membrane clamping device is to turn with rotation axis
Dynamic connection makes it that can be rotated around the rotation axis opposite flow cover and pedestal, web plate be arranged on filter membrane clamping device and pedestal it
Between, retention mechanism is connected between kuppe and pedestal to slide along rotation axis and then by filter membrane clamping machine for control kuppe
Structure clamps.
Compared with the prior art, the utility model has the advantages that：
1st, it is convenient to change film, it is only necessary to unclamp retention mechanism and then screw out filter membrane clamping device.
2nd, filter membrane takes out simpler from clamping device, and dust thereon is avoided to trickle down, influences sampling precision.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the rotation axis, pedestal and kuppe connection relationship diagram.
Specific embodiment
It is described in detail the particular content of the utility model with reference to the accompanying drawings and examples.
As shown in Figures 1 and 2, the utility model provides a kind of dust sampling meter, including shell 1 and is sequentially connected
Motor, aspiration pump, flowmeter and sampling head, wherein, motor, aspiration pump and flowmeter are fixed on inside shell 1, sampling head
It is fixed on horizontal boom state on shell 1, shell 1 is equipped with handle 6.
The sampling head is cylindrical shape, including pedestal 2, web plate 92, filter membrane clamping device, retention mechanism and kuppe 4, institute
It states pedestal 2 to be fixed on shell 1, the kuppe 4, filter membrane clamping device and pedestal 2 pass through horizontal and eccentric setting rotation
Axis 8 connects, and for the filter membrane clamping device between kuppe 4 and pedestal 2, the kuppe 4 is the company of slip with rotation axis 8
It connects, the filter membrane clamping device makes it that can be revolved around the 8 opposite flow cover 4 of rotation axis and pedestal 2 with rotation axis 8 for rotation connection
Turning, web plate is arranged between filter membrane clamping device and pedestal 2, and retention mechanism is connected between kuppe 4 and pedestal 2, for
Control kuppe 4 slides along rotation axis 8 and then filter membrane is clamped gear grips.The retention mechanism is lock 5.The web plate 92
For expanded sheet metal, the pedestal 2 is equipped with the web plate slot 91 of installation web plate 92.
The filter membrane clamping device includes the first clamping piece 31 and the second clamping piece 32, the first clamping piece 31 and the second clamping
Piece 32 is the cirque structure of elastic material, and its one end is equipped with hand and dials portion 7, and one end that portion 7 is dialled away from hand is equipped with for rotating
Axis 8 by rotation hole.
During actual samples, filter membrane is placed between the first clamping piece 31 and the second clamping piece 32, hand is then rotated and dials portion 7,
The first clamping piece 31 and the second clamping piece 32 is made extremely to align around the rotation of rotation axis 8 with the outer surface of pedestal 2 and kuppe 4, button
Upper lock 5, start work repeat the above steps once, it is necessary to then be upsided down when taking out filter membrane.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover among the right of the utility model.
