Dust deposition detecting and sensing unit, system and method

Abstract

The invention discloses a dust deposition detecting and sensing unit, system and method. The dust deposition detecting and sensing unit comprises a detecting hole, a dust accumulating hopper and a weighing sensor assembly, wherein the detecting hole is formed in the bottom of a dust collection pipeline; the dust accumulating hopper is used for accumulating the dust depositing at the bottom of thedust collection pipeline; the bottom of the dust accumulating hopper is in contact connection with a weighing surface of the weighing sensor assembly; the sensing unit can realize online continuous monitoring and does not require separate weight test after dust collection, so as to monitor the dust thickness on the dust collection pipeline in real time. Signals output by a weighing sensor are processed by filtering, analog-digital conversion, moving average, singular value removal, vibration interference removal and the like, thus the influence on the test result caused by the vibration interference from the complicated test environment and the creep property of the weighing sensor is reduced, average dust thickness of unit area in the dust collection pipeline can be tested accurately, andthe prediction of dust explosion can be realized.

Description

technical field [0001] The invention relates to the field of dust detection, in particular to a dust deposition detection sensing unit, system and method. Background technique [0002] In production dust workplaces such as polishing and grinding workshops, large grain processing plants, stone and wood processing plants, in order to avoid dust occupational hazards and dust explosion accidents, the production dust must be dedusted. Dust collectors are generally used to remove dust Carry out dust removal treatment; but it brings safety hazards: the dust deposition in the dust removal pipeline will produce a violent explosion when there is an ignition source (such as static electricity, friction sparks, etc.), which will bring very serious hazards. [0003] At present, there is no effective method for the detection of dust deposited in pipelines. The State Administration of Work Safety's "Five Regulations on Strictly Preventing Dust Explosions in Enterprises" stipulates that "th...
