The invention discloses a self-insulation autoclaved aerated concrete block production device, comprising an agitator tank. A rotary gland is connected with one side of the agitator tank, a delivery pipe is fixed to the top end of the agitator tank, a connecting rod is connected with the inner wall of the agitator tank, an arc scraper plate is arranged at the position, below the connecting rod, close to the inner wall of the agitator tank, a heater is mounted at the position, close to the outer side of the arc scraper plate, of the inner side of the agitator tank, a sealing plate is arranged at the top end of the rotary gland, an electromagnetic valve is arranged on the outer surface of the delivery pipe, a fixing plate is mounted at the bottom end of the deliver pipe, and the inner wall of the fixing plate is connected with a conveyor belt. With the arrangement of the conveyor belt and a shaping groove, the conveyor belt drives the shaping groove to enter the next process after the shaping groove is filled with products, so that manual carrying process is omitted, and work efficiency is improved effectively; with the arrangement of the sealing plate, the contact area between the rotary gland and the inner wall of the agitator tank is expanded, and thus air-tightness of the device is improved greatly.
