Dust monitoring device

Abstract

The invention discloses a dust monitoring device. The device comprises a dust monitoring main body, an air inlet is formed in the middle of the top of the dust monitoring main body, an air outlet is formed in the middle of the bottom of the dust monitoring main body, an integral arch protrusion and two supporting main frames are arranged at the bottom of the dust monitoring main body, the two supporting main frames are located behind the air outlet, a support sub-frame is arranged at the bottom of the arch protrusion, a dust monitoring system is arranged in the dust monitoring main body and the arch protrusion, an air inlet end of the dust monitoring system is in butt joint with the air inlet, an air outlet end of the dust monitoring system is in butt joint with the air outlet, and a display screen is connected with the dust monitoring system and used for displaying monitoring data of the dust monitoring system. In application, dust monitoring can be conducted in the complex environment under a mine, and meanwhile the measurement accuracy of dust under the mine can be effectively improved.

Description

Technical field [0001] The invention relates to the technical field of dust monitoring, in particular to a dust monitoring device. Background technique [0002] General underground mine operations are usually accompanied by the generation of a large amount of dust. If too many dust particles in the air are inhaled into the body, it will pose a great threat to the health of the operators. Therefore, it is best to monitor the air in real time for underground operations. The dust concentration. [0003] For the measurement of dust concentration, there are mainly the following methods: One is filter membrane dust measurement. The specific operation is to pass a certain volume of dust-laden air through the sampling head, and all dust particles of different sizes are trapped in the sampling head. The inner surface of the filter membrane, according to the weight gain of the filter membrane and the volume of air passing through the sampling head, calculate the dust concentration in the ai...

Problems solved by technology

This method is not only inconvenient to operate, but also cannot measure continuously; the other is a direct-reading dust meter, which mainly uses indirect methods such as incandescent lamp transmission, infrared light transmission, light scattering, laser scattering, β-ray absorption and other principles , use the sampler to calibrate, and the measured dust concentration value can be displayed immediately

[0004] The existing air dust detection device mainly has the following problems when it is used in the mine: 1. The operating environment in the mine is complicated, and the existing air dust detection device is too large in size, which is not easy to carry and directly placed and used in the mine; 2. When the existing air dust detection device is used in mines with complex environments, its measurement accuracy is not high and needs to be improved; 3. The resources that can be carried in underground operations are limited. If the dust detection device is only used for dust measurement, play a very limited role
