Flow restriction coating device for insulating hydrophobic dustproof coating film of double-layer explosion-proof lamp

The invention relates to the field of explosion-proof lamps, in particular to a flow restriction coating device for an insulating hydrophobic dustproof coating film of a double-layer explosion-proof lamp. The technical problem to be solved is to provide the flow restriction coating device for the insulating hydrophobic dustproof coating film of the double-layer explosion-proof lamp. The flow restriction coating device for an insulating hydrophobic dustproof coating film of the double-layer explosion-proof lamp comprises a bottom plate assembly, a cleaning unit and the like, wherein the bottom plate assembly is connected to the cleaning unit. According to the device, the surface of the double-layer explosion-proof lamp is cleaned, then the upper layer of the double-layer explosion-proof lamp is coated with an insulating dustproof film, the insulating dustproof film on the surface of the upper layer is evenly scraped, then the scraped insulating dustproof film coats the outer ring face of the upper layer, then
