Dust explosion-proof system for medium-density fiberboard paving section

Abstract

The invention discloses a dust explosion-proof system for a medium-density fiberboard paving section. The dust explosion-proof system comprises an unloading rear door on a paving bin, rupture disks, aflameless explosion venting device and an explosion isolation device, the unloading rear door is close to an outdoor waste stacking field, and a plurality of rupture disks are mounted on the unloading rear door; the flameless explosion venting device is integrated by two parts, namely the rupture disk and a flame filter, the explosion isolation device is composed of an explosion suppression device and a spark detection probe, and the explosion suppression device is filled with powdery inhibitors. The invention provides a novel system which can be configured in the current paving section, cantimely release explosion when explosion occurs and can prevent explosion from spreading to the whole production line.

Description

technical field [0001] The invention relates to a medium-density fiberboard paving machine, in particular to a dust explosion-proof system for a medium-density fiberboard paving section capable of venting and explosion-proof protection equipment and operators. Background technique [0002] A large amount of dried wood fibers are stored in the equipment of the MDF pavement section, and are scattered under the action of mechanical parts. The length is between 0.12mm and 2mm, and the moisture content is within 3% to 10%. Fiber occupies a large proportion. Therefore, these light and dry wood fibers are easily lifted and suspended in the equipment in the paving section, creating a dust-hazardous environment in the confined space. If a sufficiently high energy source, such as a spark, is generated due to mechanical or electronic component failure of the equipment, a dust explosion will be caused in the dust environment. The shock wave generated by the explosion will not only cau...

Problems solved by technology

[0005] One of the technical problems to be solved by the present invention is that the existing paving machine equipment configuration cannot completely eliminate the hidden dangers of dust explosion inside the equipment, and once an explosion occurs, the life of the operator and the explosion-proof safety of the upstream and downstream related equipment cannot be completely protected. problem, but to provide a dust explosion-proof system that can be configured in the current pavement section, which can vent the explosion in time and prevent the explosion from spreading to the entire production line of the factory.
