Description
Technical field:
The utility model relates to the sensor of dust concentration field, is specifically related to a kind of novel sensor of dust concentration.
Background technology:
Sensor of dust concentration is mainly used in the continuous monitoring of the dust work place total dust concentrations such as mine, cement mill.It is the high-tech sensor that utilizes the light scattering principle exploitation in order to satisfy existing mine monitoring downhole powder dust concentration, can be under the natural airflow state real-time, on the spot, continuous continual monitoring shows the dust concentration in operation place, simultaneously output and the switching value signal of sprinkle water and spray device for reducing dust has realized the optimum efficiency of dust measuring depositing dust.
The light source of existing sensor of dust concentration and photomultiplier in the same horizontal line, light source all subjects to the pollution of dust with photomultiplier in the process that detects, and reduces serviceable life, and later maintenance is difficult.
The photomultiplier of present sensor of dust concentration on the market is arranged in the darkroom more, places for a long time dust can affect the accuracy of detection of sensor of dust concentration.
The utility model content:
The purpose of this utility model provides a kind of novel sensor of dust concentration, and it is simple in structure, and is easy to operate, avoids light source and photomultiplier to be subject to the pollution of dust, can improve sensor serviceable life and accuracy of detection.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises darkroom 1, blower fan 2, fair water fin 3, photohole 4, light source 5, shell 6, air intake opening 7, hermetically-sealed construction 8, photomultiplier 9 and testing window 10; Darkroom 1, blower fan 2 and hermetically-sealed construction 8 all are arranged in the shell 6, fair water fin 3 is arranged in the darkroom 1, the lower end in darkroom 1 is connected with blower fan 2, photohole 4 is arranged on a side of 1 upper end, darkroom, the opposite side of 1 upper end, darkroom is provided with air intake opening 7, is provided with light source 5 in the air intake opening 7, and the top in darkroom 1 is provided with testing window 10, testing window 10 is connected with hermetically-sealed construction 8, is provided with photomultiplier 9 in the hermetically-sealed construction 8.
Described fair water fin 3 is placed in the darkroom 1 at an angle, is convenient to the dust water conservancy diversion that will suck.
Described photomultiplier 9 is a kind of light-detecting devices with high sensitivity and ultrafast time response.
During the utility model operation, by blower fan dust is sucked in the darkroom 1, under the effect of fair water fin 3, dust is taken advantage of a situation through testing window 10, in through testing window 10 processes, light source 5 is radiated on the dust, dust is more, and scattered light intensity is larger, and photomultiplier 9 detects the index of dust concentration in the testing window 10, during detection, photomultiplier 9 can not be subject to the pollution of dust.
The utility model is simple in structure, and is easy to operate, avoids light source and photomultiplier to be subject to the pollution of dust, can improve sensor serviceable life and accuracy of detection.
