Pressurization pre-wetting equipment of light aggregate

The utility model relates to pressure pre-wetting equipment for light-weight aggregate, which is a can-shaped, closed pressure vessel. A can body of the closed pressure vessel thereof is supported on a chassis of a concrete mixing haulage vehicle; an annular plate is welded around a discharge hole at the rear end of the can body; a pressure sealing cover covers the annular plate; the pressure sealing cover is provided with a bleed hole and a water injection hole; the bleed hole is connected with a deflation valve. A rubber packing is arranged on the contact face between the annular plate and the pressure sealing cover; corresponding screws are evenly distributed on the edges of the pressure sealing cover and the annular plate; the pressure sealing cover and the annular plate are fixedly connected with each other through a screw and a nut. The utility model has the advantages of simple structure, low manufacturing cost, rapid light-weight aggregate pre-wetting speed and high pre-wetting efficiency. The light-w
