Description
Technical field
The present invention relates to air testing equipment field, in particular to a kind of atmosphere particulate matter sampler.
Background technology
Atmosphere particulate matter sampler, which can be realized, carries out the suspended particulate substance in air (including TSP, PM10, PM2.5 etc.)
Continuous automatic sampling.The suspended particulate substance sample collected is collected on filter membrane, to be analyzed using various means, from
And obtain various chemical analysis information included in suspended particulate matter concentration and suspended particulate substance.
As depicted in figs. 1 and 2, atmosphere particulate matter sampler mainly realizes automatic loading filter membrane 1, acquisition sample, recycling filter
1 three functions of film.Under normal conditions, filter membrane 1 is installed in the filter membrane casket 1 of standard, by manually filling a certain number of filter membrane caskets 2
Enter in a special storage diaphragm 4 and be fitted into the storage diaphragm 4 in the storage diaphragm seat 3 taken at film location A, the effect of storage diaphragm seat 3 is
Fixed storage diaphragm 4 and make storage diaphragm 4 card bead 6 be in retraction release conditions (at this time filter membrane casket 2 be in can free-falling shape
State)；Another empty diaphragm 4 of storing is fitted into the storage diaphragm seat 5 at the C of winder position, the effect of storage diaphragm seat 5 is fixed storage diaphragm 4
And make storage diaphragm 4 card bead 6 keep pop-up envelope card-like state (the filter membrane casket 2 recycled at this time be in it is non-can free-falling shape
State)；After starting sampler, sampler is automatically performed loading filter membrane casket 2, acquisition sample, then the filter membrane casket 2 for having gathered sample is returned
Receive the course of work in empty storage diaphragm 4.
In the prior art, the mode of atmosphere particulate matter sampler transmission filter membrane casket 2 is typically using Linear transmission mode.
It is a kind of 2 transmission mechanism application examples of filter membrane casket of the prior art as shown in Figure 3 and Figure 4.
In this mechanism, 23 forward and reverse rotation of driving motor is dragged by synchronizing wheel 14, synchronous belt 15, connector 37
Driver plate 21 is moved between film location A, sampling location B, winder position C taking, to realize filter membrane casket 2 from film location A is taken to move
To sampling location B, winder position C is then moved to after sampling.31 forward and reverse rotation of motor is jacked, driving quadric chain realization will adopt
Sample cylinder 28, winder jacking body 24 jack up simultaneously, the filter membrane casket 2 (being shown in Fig. 2) at the B of sampling location jacked by sampling cylinder 28 after and
The air intake sealing ring 8 (being shown in Fig. 2) of its upper part compresses to realize that sealing is evacuated (sampling), the filter membrane casket 2 at the C of winder position
It is pushed by winder jacking body 24 in the special storage diaphragm 4 of its upper part.The effect of bearing plate 16 is to fill up driver plate 21 immediately to remove
Space when taking film location A below filter membrane casket 2 makes filter membrane casket 2 fall on bearing plate 16 and keep being slightly above on driver plate 21
The position on surface so takes film location A and when pushing bearing plate 16 open when driver plate 21 is moved back to, and filter membrane casket 2 can be in driver plate 21
It is opposite above to slide and fall into the slotted hole of driver plate 21.
The main problem of this mechanism is：
First, structure is more complicated.1st, because motor output is flywheel moment, just must if it is desired to be performed component and obtain linear motion
Corresponding transmission mechanism must be increased, as in this example synchronizing wheel 14, synchronous belt 15 and swelling device 11, the installation of synchronous pulley tensioner
Plate 33, directive wheel 38 etc.；2nd, corresponding guider must independently be increased by obtaining linear motion, such as driver plate/undertaking in this example
Panel guide 36；3rd, catching device must be increased, with fill up immediately driver plate 21 remove take film location A when filter membrane casket 2 below space,
Bearing plate 16, bearing plate guide rod 12, bearing plate resetting spring 13 in such as this example；4th, quadric chain part is more, manufacture
It is larger with installation difficulty；
2nd, it is laid out unreasonable.Take film location A, sampling location B, winder position C is arranged in a linear inevitably to increase
The width of sampler causes sampler volume and weight to increase；
3rd, poor fault tolerance.4 optoelectronic switches 35 are used in this example altogether, position letter is moved back and forth to driver plate 21 to realize
The feedback of breath has used 2 travel switches 18 and travel switch 20 to realize the control for jacking up and resetting to quadric chain.If
Wherein a certain switching signal or electric machine control system break down, it would be possible to motor one direction be caused can not stall, due to the machine
It is difficult to set disengagable formula connecting link in structure, therefore easily causes motor and be in overcurrent condition and damage；
4th, manufacture and maintenance cost are higher.Since there are structure is more complicated, volume and weight is larger, mechanism poor fault tolerance
The problems such as, it will inevitably increase sampler manufacture and maintenance cost.
