The invention discloses a production device for an aerated concrete sandwich SPF hard bubble block self-insulation wall. The production device structurally comprises a numerical control cabinet, a stirrer, a speed reducer, a feed inlet, a screening unit, a producer body, a bottom plate, a motor and a driver, wherein the bottom plate is of a cuboid structure with the two side surfaces being the same and parallel to each other, the top surface of the bottom plate is arranged on the surface of the bottom of the producer body and perpendicular to the surface of the bottom of the producer body, andthe width of the bottom plate is 60 cm; and the driver is hexagonal, the interior and the exterior of the driver are solid, the side surfaces of the driver are movably connected with the side surfaces of the producer body in a welding fit mode, and the width of the driver is 6-10 cm. The production device has the beneficial effects that the screening unit is arranged, after a screening unit bodyis powered on, materials are filtered at the feed inlet through a filtering net and fed onto a screening net, raw material impurities on the screening net are screened by the screening unit body, thecompactness of the block wall is prevented from being poor, and the production quality is effectively improved.
