End face fitting, assay balance is additionally provided between two pieces of support plates, the assay balance is equipped with weighing plate, the filtering
The bottom of plate is located on weighing plate.
Working principle of the utility model is:
Airborne suspended particulate detection device in the utility model, in use, being first moved to whole device to be measured
Reading (the i.e. filter plate of assay balance is first recorded before detection because the bottom of filter plate is located on weighing plate in position
Weight), the then exhaust fan on start-up operation platform, air just enters from air inlet pipe, passes through because the upper surface of station is equipped with
The through-hole of dress operation platform, filter plate are slidably connected with through-hole, and through-hole is between air inlet pipe and snorkel, snorkel and exhaust fan
Connection, the end face of the other end of the side and snorkel of filter plate are bonded, the other side of filter plate and the end face of air inlet pipe one end
Fitting after air enters from air inlet pipe, is led to so filter plate just plays the role of blocking between snorkel and air inlet pipe
It crosses filter plate just to intercept the suspended particulate substance in air, when taken out air reaches a certain amount of, closes exhaust fan, then
In the reading checked on assay balance, the reading recorded twice is compared and then can be obtained by a difference, it can be right
The airborne suspended particulate of position to be measured is detected, when needing to detect the suspended particulate substance in other positions air again,
It only needs to remove filter plate and carries out clean or replacement filter plate, then repeatedly aforesaid operations.
The utility model has the beneficial effects that
When being detected using this programme to the suspended particulate substance in air, it is only necessary to pass through the analysis day below station
It is flat first to record the weight for detecting preceding filter plate, then start exhaust fan, air just enters from air inlet pipe, then passes through filter plate
It enters back into snorkel, the suspended particulate substance in air can be intercepted by filter plate, be then shut off exhaust fan, then
Secondary to be read by assay balance, difference between the two is exactly the weight of suspended particulate substance in air.Compared with prior art
For, this programme is used as driving using exhaust fan, and only needs to have reached operation by the measurement to filter plate weight
Simply, long service life and the low effect of maintenance cost.
Further, the weighing plate is equipped with placing groove, and the low side of the filter plate is slidably socketed in placing groove.In this way
It is more stable to allow for filter plate.
Further, the filter plate is equipped with handle.Filter plate is needed replacing or is cleaned after, by mistake
With regard to more convenient when handle, replacement or cleaning being arranged on filter plate.
Further, the side wall of the filter plate is bonded with the cell wall of through-hole.Thus effectively prevent filter plate
Offset, so that air-tightness is more preferable.
Further, the bottom of two pieces of support plates is equipped with the universal wheel of strap brake.Detect suspended particulate substance in air
When, it inevitably needs to detect different places, by the way that the universal wheel of strap brake, mobile support are arranged in the bottom of support plate
Plate is with regard to more convenient laborsaving.
