Mouthful enter in the darkroom, the laser generator by the light inlet towards directional light is launched in the darkroom, it is described whole
Plate is flowed in the darkroom, and the optical-electrical converter is at the light-emitting window in the darkroom, and the steel shell is provided with shape
State indicator lamp, digital display screen and set keyboard, the optical-electrical converter, the status indicator lamp, the digital display screen and
The setting keyboard connects the master control borad respectively.
Above-mentioned dust concentration monitor, wherein, the top of the steel shell is provided with installation suspension ring.
Compared with the prior art, the beneficial effects of the utility model are：
Compact conformation, carries convenient for installation and maintenance, can continuously detect the ring that there is inflammable and explosive combustible gas mixture
Swum in border the concentration of dust, with measurement quick and precisely, the features such as sensitivity is high, performance is stable, can be with various monitoring systems
Support the use, to the total dust of Work places in the working environment for being widely used in having inflammable and explosive combustible gas mixture
Continuous monitoring, while being also applied for the environmental monitoring of other public places.
Brief description of the drawings
Constitute a part of accompanying drawing of the present utility model to be used for providing further understanding to of the present utility model, this practicality is new
The schematic description and description of type is used to explain the utility model, does not constitute to improper restriction of the present utility model.
In accompanying drawing：
Fig. 1 shows the internal structure schematic diagram of the utility model dust concentration monitor；
Fig. 2 shows the external structure schematic diagram of the utility model dust concentration monitor.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
With reference to shown in Fig. 1, Fig. 2, the utility model dust concentration monitor includes steel shell 1 and located at steel shell
Optical-electrical converter 2, laser generator 3, darkroom 4, cowling panel 5, air exhauster 6 and master control borad 7 in body 1, steel shell 1 are provided with
Interface socket 8, air inlet 9 and exhaust outlet 10, darkroom 4 are provided with light inlet 11 and light-emitting window 12, and extraneous air is in air exhauster 6
Entered under suction by air inlet 9 in darkroom 4, laser generator 3 by light inlet 11 towards directional light is launched in darkroom 4, it is whole
Plate 5 is flowed in darkroom 4, and optical-electrical converter 2 is at the light-emitting window 12 in darkroom 4, and steel shell 1 is provided with status indicator lamp
13rd, digital display screen 14 and setting keyboard 15, optical-electrical converter 2, status indicator lamp 13, digital display screen 14 and setting keyboard 15
Master control borad 7 is connected respectively.In the technical program, the top of steel shell 1 is provided with the convenient installation suspension ring 16 installed.
Extraneous air is entered behind the darkroom 4 of monitor under the suction of air exhauster 6 by air inlet 9, swimming in air
During the parallel light irradiation that dust is sent by laser generator 3 in the darkroom 4, it is dense that the scattered light intensity of dust is proportional to quality
Degree, the scattered light is converted into photoelectric current by optical-electrical converter 2, and the photoelectric current integrating circuit through master control borad 7 is converted into and scattered
The photoimpact number that light intensity is directly proportional.The relative mass concentration of dust can be measured by calculating umber of pulse, by demarcating in set key
K values are preset on disk 15, the bug dust concentration (mg/m in air just can be directly shown during work on digital display screen 143)。
From above-described embodiment as can be seen that advantage of the present utility model is：
Compact conformation, carries convenient for installation and maintenance, can continuously detect the ring that there is inflammable and explosive combustible gas mixture
Swum in border the concentration of dust, with measurement quick and precisely, the features such as sensitivity is high, performance is stable, can be with various monitoring systems
Support the use, to the total dust of Work places in the working environment for being widely used in having inflammable and explosive combustible gas mixture
Continuous monitoring, while being also applied for the environmental monitoring of other public places.
Specific embodiment of the utility model is described in detail above, but the utility model is not restricted to the above
