It is very remote.Dust is done great harm to human beings, and especially the measurement of small size particle therefore dust concentration is in field of environment protection
It has a very important significance, is problem in the urgent need to address.
The utility model is while to need the item according to testing location to as this larger particles of chalk dust detect
Part, being designed to dust receiving port keeps it adjustable.This particle being relatively large in diameter of chalk dust, the process landed in the sky
In have certain track, need to carry out dust collection through the place of falling to the dust of different location.
Utility model content
The purpose of this utility model is that it is regarding to the issue above and insufficient, propose that one kind can carry out range to a certain region
Interior fixed point acquires dust, band drawing and pulling type dust collecting box, the device of acquisition dust simple for structure.
To solve the above-mentioned problems, the following technical solution is provided：
A kind of device acquiring dust, it is characterised in that：The powder being centrosymmetrically arranged including four around center column (2)
Dirt mouth (1) setting is led at the top of dust passage (11) in dirt channel (11)；Each dust passage (11) bottom is all connected with a ventilation
Road (6), each dust passage (11) are connected with center column (2) lower part by respective ventilating duct (6) respectively, ventilating duct (6) and
The gas vent (8) of center column (2) bottom is connected；Two connecting rods (3) extend through center column (2) top for center pair
Claim four dust passages (11) connection of arrangement, aspiration column (12) is connected by air inlet (10) with gas vent (8).
Further, dust collecting box (5) can dismantle setting in dust passage (11) middle part or bottom.
Further, the sealing telescopic band (7) of four PVC materials surround center column (2) lower part for central symmetry respectively
Four ventilating ducts (6) of arrangement are connected.
Further, in connecting rod slideway (4) centrally disposed cylinder, connecting rod (3) runs through the part of center column (2)
It is arranged on connecting rod slideway (4).
The beneficial effect of the utility model：
(1) present apparatus can be in neutrality the dust for being arranged symmetrically acquisition different location.
(2) aspiration column provides quantitative gas sucking effect, can play the wind direction guiding function for leading dirt mouth at work, make
Dust swimmingly enters dust and receives in dust collecting box.
(3) angle, multi-faceted acquisition dust are determined by four 90 ° of dust passage, multiregion multisample carries out the flat of data
Equal evaluation, can reduce detection error.
(4) dust collecting box for facilitating taking-up is set in dust passage, and the gas outlet of aspiration column connects closed bag.
