The utility model provides an anti-paint mist sealing device, a corresponding double-chain conveyor and a corresponding painting chamber. The anti-paint mist sealing device comprises an open bracket and a plurality of sealing protection plates similar in structure. The sealing protection plates vertically overplay the horizontal plane at the upper end of a conveyor outer casing and fixedly connected with one another through fasteners vertically extending. The sealing protection plates are linearly arranged. Free ends of the sealing protection plates obliquely bend upwards. The lower sealing protection plate overlaps the sealing protection above the same in the front-and-back direction and forwardly protrudes the above one. The free end of the uppermost sealing protection plate is arranged outside a slide vertical column. The sealing protection plates cover clearances of the conveyor outer casing and a conveyor inner casing. The anti-paint mist sealing device is applicable to double-chain conveyors and further applicable to automatic painting systems.
