Description
Technical field
The utility model provides a kind of quality of air environment monitoring device, belongs to metallic dust monitoring technical field.
Background technology
During the Carving Machining of the metal handicrafts such as tungsten, tin, molybdenum, bismuth is carried out, substantial amounts of metallic dust can be produced, this
Kind metallic dust causes the harm to environment, and especially when metallic dust is spread in atmosphere, harm to the human body is very big.Although at present
Processing site be designed with dust arrester, but whether the operating efficiency of dust arrester reaches dust removal requirement, the air matter after dedusting
Whether amount still exists to human body is endangered, and there is no the equipment that air quality monitoring is carried out for metallic dust at present.
The content of the invention
To solve the above problems, the utility model provides a kind of quality of air environment monitoring device, concrete scheme is：
A kind of quality of air environment monitoring device, including housing, the housing are insulation shell, and housing forward end is provided with air intake
Mouthful, housing rear end is provided with air-vent, and air-vent is used to be connected with air-introduced machine, and enclosure interior is provided with and connected with air inlet and air-vent
Accommodating cavity；Vertically disposed polylith dust-filtering plate is provided with the accommodating cavity, the filtering accuracy of dust-filtering plate is increased by airflow direction；
The upper and lower ends of every piece of dust-filtering plate are connected with independent monitoring electrode, and monitoring electrode is used to be connected with electrical resistance monitoring circuit.
Further, the rear end of the housing is provided with blowback air port, and the bottom of the dust filtration plate is provided with cinder-discharging port；It is described anti-
Blowing mouth is used to connect back blowing machine, and the back blowing machine and air-introduced machine are provided with time-delay relay.
Further, the lateral surface of the dust filtration plate gathers groove provided with vertically disposed dust, and dust gathers groove insertion filter
The upper and lower ends of dirt plate, and connected with the monitoring electrode of dust-filtering plate upper and lower ends.
Further, it is V-shaped groove that the dust, which gathers groove,.
Further, the height of the dust filtration plate is 20~50mm, and width is 80~120mm.
Further, the dust filtration plate is polyester fiber board.
Further, the air intake epistome is provided with cone expansion mouth.
Beneficial point of the present utility model is：Operation principle in this programme is to be deposited according to metallic dust on dust-filtering plate
Afterwards, the resistance change of dust-filtering plate is monitored, when metallic dust concentration is high in air, sunk in the unit interval on dust-filtering plate
Long-pending metallic dust thickness is bigger, and the resistance value that dust-filtering plate both ends monitoring electrode monitors is smaller.
Electrical resistance monitoring circuit in this programme can be designed to continuously monitor on-line, with reference to cleaning of the back-blowing to dust-filtering plate
Frequency, can be with the curve of cyclical fluctuations of real-time monitored resistance value signal, so as to intuitively reflect the concentration of metallic dust in air.
