The invention relates to a waste gas filter with an M-shaped filtering medium. The waste gas filter is applied to treatment or recycling of organic waste gases or inorganic waste gases generated in spraying and painting processes of industrial manufacturing of furniture, automobiles, containers, shipbuilding and the like. The waste gas filter comprises a base and filters, wherein a waste gas inlet and a waste gas outlet are formed in the base. The waste gas filter is characterized by further comprising an M-shaped bracket; the M-shaped bracket is mounted on a channel through which a waste gas flows to the waste gas outlet from the waste gas inlet inside the base; the filters are adhered to working surfaces on two inner sides of each V-shaped hole of the M-shaped bracket. The waste gas filter has the advantages that the baffling area of unit volume of each filter is large, the filtering efficiency is improved, the size of a filter in the prior art is reduced, meanwhile, as the filters are arranged in the flowing direction of the waste gas, the energy loss of the flowing waste gas is reduced, the power of a fan is reduced, the filtration effect is stable, and the like.

The logistics conveying device comprises a supporting plate, supporting wheels are arranged on the lower side of the supporting plate, a mounting frame is arranged above the supporting plate and comprises two round rollers, the distances between the two round rollers and the supporting plate are different, positioning plates are arranged on the two sides of each round roller, and the positioning plates are arranged on the two sides of each round roller.
