Description
Technical field
The utility model relates to a kind of airborne particle counter transmitter.
Background technology
The toilet is one, and the first step of control particulate is the quantitative analysis to particulate for airborne particulate in the space being done the special closure building that control is built, and just the particle diameter of particulate and quantity are carried out quantitative analysis.At present, no matter be domestic or external, institute's foundation all be airborne particle counter, its principle all is to use a kind of sampling pump, extracts air in certain amount, by specific transmitter, obtain the size of particulate and the quantity of corresponding particle, the sampling pump that above-mentioned airborne particle counter is mentioned has many manufacturers that meet the demands both at home and abroad, the reason that Here it is extensively adopts.But on the other hand, its consumed power, noise pollution is serious, and serviceable life is short.Because volume is bigger, cause corpuscular counter comparatively heavy again, use inconvenient.
The utility model content
The purpose of this utility model is: a kind of airborne particle counter transmitter is provided, and it is simple in structure, long service life, energy consumption are low, and cost is low, Control Flow accurate and flexible, safe and reliable.
The technical solution of the utility model is: a kind of airborne particle counter transmitter, it comprises sensor, signal processing controller, described sensor comprises semiconductor laser, adjustment seat, cavity, outlet nozzle, admission piece, light trapping, photoelectric commutator, photoelectric commutator connects signal processing controller, and described admission piece is provided with well heater.
Described well heater is equipped with temperature sensor, and described temperature sensor connects signal processing controller.
Described signal processing controller connects well heater.
The utlity model has following advantage:
1. airborne particle counter transmitter of the present utility model, because the internal heater that adopts substitutes the sample mode of air pump and flowmeter, therefore need not sampling pump and flowmeter, have quiet, energy-conservation, long service life, low cost, Control Flow accurately and flexibly, low fault, characteristics such as safe and reliable, be convenient to miniaturization, integrated processing, easy to carry and energy-conserving and environment-protective, the Long-distance Control simple and flexible.
2. airborne particle counter transmitter of the present utility model, the employing well heater replaces air pump and the flowmeter in the original airborne particle counter, is installed in the airborne particle counter transmitter, reduce fault, improve integrated level, cut down the consumption of energy, Long-distance Control is simple and convenient.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an air flow rate control synoptic diagram of the present utility model;
Fig. 3 is the structural representation of sensor of the present utility model.
Wherein: 1 semiconductor laser; 2 adjustment seats; 3 cavitys; 4 outlet nozzles; 5 light trappings; 6 photoelectric commutators; 7 admission pieces; 8 well heaters; 9 temperature sensors; 10 sensors; 20 signal processing controllers; 30 air ducts.
Embodiment
Embodiment: as shown in Figure 1, a kind of airborne particle counter transmitter, it comprises sensor 10, signal processing controller 20.
As Fig. 1, shown in Figure 3, sensor 10 comprises semiconductor laser 1, adjustment seat 2, cavity 3, outlet nozzle 4, admission piece 7, light trapping 5, photoelectric commutator 6.Photoelectric commutator 6 connects signal processing controller 20.Admission piece 4 is provided with well heater 8, and well heater 8 is equipped with temperature sensor 9.
As shown in Figure 2, temperature sensor 9 connects signal processing controller 20, and signal processing controller 20 connects control heater 8.
The principle design that this transmitter up flows according to hot-air, internal heater 8 in sensor 10.During test, well heater 8 work are flowed air in pipeline 30, and the dust that flows sends scattered light by laser beam irradiation the time, and this scattered light just can detect particle after being responded to by photo detector, can identify grain size and amounts of particles through handling.Simultaneously, the temperature of control heater 8 can directly be controlled the flow velocity of air-flow, and well heater 8 thermostatically controlled gas streams are also constant, so flow can accurately be controlled automatically.
Should be pointed out that for the utility model also to have the embodiment of multiple conversion and remodeling, be not limited to above-mentioned specific embodiment through proving absolutely.In a word, protection domain of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
