As disclosed in the background art, the existing core shooter is generally composed of a catalyst quantifying device, an air preheater and a catalyst heater, and is integrated and then placed on a shell platform, and when in actual blowing, a blowing pipe needs to be extended to the blowing cover by the shell platform due to the fact that the shell platform is far away from a mounting frame and a blowing cover, and the tube pass is long, so that heat loss is easy to cause.
Further, since the air-blowing hood generally needs to be moved back and forth under the mounting frame, in order to accommodate the air-blowing hood, it is generally necessary to additionally provide a hose section for the air-blowing hood to be moved in and out, and the hose section is connected with the air-blowing hood after bypassing the edge of the mounting frame, which definitely further causes an increase in the tube side, so that heat loss is aggravated.
