Abstract

The invention discloses a spark detection device and method of a material conveying pipe. The device comprises a filtering lens and a light guide fiber arranged in a detection area in the material conveying pipe, photoelectric sensors arranged at the two ends of the detection area in the material conveying pipe respectively and a controller connected with the photoelectric sensors. The filtering lens and light guide fiber cooperate with each other to transmit light information in the detection area to the photoelectric sensors, and the photoelectric sensors are arranged in the opposite detection direction to complete blind detection areas mutually.

Description

technical field [0001] The invention belongs to the technical field of material delivery pipelines, and in particular relates to a material delivery pipeline spark detection device and a method thereof. Background technique [0002] In recent years, sparks generated during pipeline material transportation have caused frequent combustion and explosion accidents in ventilation and dust removal systems including dust collectors, dust separators and dust collectors, and connected pipelines, and the situation continues to be severe. Especially in the process of pipeline transportation of wood, metal, tobacco and other materials, tiny electric sparks are likely to be generated due to static electricity, friction, collision and other factors and thus cause fires. When the dust reaches a certain concentration, it will cause an explosion. Due to the smallness and accidentality of the spark, it is difficult to detect and extinguish it, and there is a blind spot in the spark detection....
