The invention relates to the technical field of aerated concrete production, in particular to a steam injection device and an aerated concrete production line. The steam spraying device comprises a steam pipeline suitable for being arranged outside the stirring machine, and the first end of the steam pipeline is suitable for being connected with a steam generating device; the injector head is connected with the second end of the steam pipeline, the injector head is provided with a surface matched with the outer wall of the stirrer, and a plurality of injection holes correspondingly communicated with a plurality of openings in the stirrer are formed in the surface, so that steam is injected into the stirrer through the openings. The steam pipeline is arranged outside the stirring machine, steam in the steam pipeline is sprayed into the stirring machine through the spraying holes and the opening in the spraying head, the steam pipeline cannot make contact with slurry in the stirring machine, then the situation that the steam pipeline is abraded is effectively avoided, and the service life of the steam pipeline is prolonged.
Description
technical field [0001] The invention relates to the technical field of aerated concrete production, in particular to a steam injection device and an aerated concrete production line. Background technique [0002] In the process of preparing autoclaved aerated concrete, various liquid and solid raw materials need to be mixed evenly in a mixing drum according to a certain ratio, and then poured. During the stirring process, it is often necessary to heat the raw materials to achieve a more suitable reaction temperature and conditions. Generally, steam is used as a heat source for heating. [0003] At present, the steam pipe is usually inserted directly into the mixing drum and inserted into the raw material to heat the raw material. Due to the fast flow rate of the raw material in the mixing drum, this heating method is easy to wear the steam pipe, damage the block of the steam pipe, and the steam pipe is easy to be blocked. cause poor heating.
