Abstract
The utility model relates to a kind of laser dust sensor adopting micro-effluent fan, and laser dust sensor comprises laser emission element, laser pick-off unit, micro-effluent fan, air chamber and reflector.Laser emission element is connected with air chamber, for Emission Lasers signal; Described laser pick-off unit is connected with air chamber, for receiving laser signal; Described micro-effluent fan is installed on air chamber, for extracting the gas with dust; Described air chamber is the shaping air chamber of time processing and is provided with air intake opening; Described reflector is arranged on air chamber, for being reflected in reacted laser signal in air cavity.The micro-effluent fan adopted in the utility model solves the air pump long-play heating that traditional air pump air suction mode brings, the problem of air pump easy burn-out after heating, thus improves the serviceable life of laser dust sensor.
Description
Technical field
The utility model relates to a kind of laser dust sensor, particularly relates to a kind of laser dust sensor adopting micro-effluent fan.
Background technology
Laser dust monitor to be widely used in the industry fields such as thermoelectricity, chemical industry, waste incineration in fume emission solid particulate matter as the detection of dust.And along with the deterioration of environment, the weather phenomena such as haze are also more and more common, the detection of dust concentration become increasingly to the needs of daily life, and demand will be increasing.And laser dust sensor is the kernel component of laser dust monitor, the quality of its performance on laser dust monitor product has conclusive impact.And traditional laser dust sensor suction element employing is that air pump is bled, and adopt air pump to bleed, due to the type selecting of air pump and the operation characteristic of laser dust monitor, need long-play, long operation can cause air pump to generate heat, and very easily burns out, thus cause the serviceable life of laser dust sensor very short after air pump heating, as adopted air pump to bleed, the serviceable life of this sensor is continuous working 300 hours.As in 201020209294.6 1 kinds of laser dust particulate matter measuring apparatus and measuring system thereof being exactly the mode that this traditional air pump of employing is bled.And the utility model adopts a kind of laser dust sensor of micro-effluent fan, this kind of micro-effluent fan rate of air sucked in required not only can meet laser dust monitor detect needed for gas flow, and can be 20000 hours the long playing time, and then substantially increase the serviceable life of laser dust sensor.
Utility model content
The utility model mainly solves the technical matters existing for prior art; Provide a kind of air pump long-play heating solving traditional air pump air suction mode and bring, the problem of air pump easy burn-out after heating, thus the laser dust sensor of the micro-effluent fan of the employing that improve the serviceable life of laser dust sensor.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
Adopt a laser dust sensor for micro-effluent fan, comprise laser emission element, laser pick-off unit, air chamber and reflector; Laser emission element is installed on air chamber by seal, for Emission Lasers signal; Laser pick-off unit is installed on air chamber by seal, for receiving laser signal; Air chamber is the shaping air chamber of time processing and is provided with air intake opening; Reflector is arranged on air chamber by seal, for being reflected in reacted laser signal in air cavity; It is characterized in that, one end of two axle head air inlet face of micro-effluent fan closed by micro-effluent fan by pressing plate and O-ring seal, be arranged on air chamber by O-ring seal again, this end air inlet face of micro-effluent fan is communicated with the air intake opening of air chamber, passes through detection air cavity for the gas extracted with dust; The lateral flow orifices of micro-effluent fan is vented as whole air chamber gas outlet.
Central inventive structure of the present utility model is: 1. by a face closure of 2 axle head air inlet face of micro-effluent fan; 2. the another side of 2 axle head air inlet face of micro-effluent fan is installed on air chamber, and is communicated with the air intake opening of air chamber by air chamber cavity; 3. the lateral flow orifices of micro-effluent fan is vented as whole air chamber gas outlet.
Therefore, the utility model tool has the following advantages: micro-effluent fan solves the air pump long-play heating that traditional air pump air suction mode brings, the problem of air pump easy burn-out after heating, thus improves the serviceable life of laser dust sensor.
