Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating brick production, in particular to a core-injecting device for cement foamed exterior wall heat-insulating bricks. Background Art

[0002] Cement foam insulation brick is a commonly used building material with good thermal insulation and heat insulation properties. In the process of manufacturing cement foam insulation brick, the staff mixes cement, water and an appropriate amount of foaming agent in a mixing tank. The stirring of the stirring blade makes the foaming agent fully dispersed and generates bubbles, so that foaming is generated in the cement mixture. Then, the mixed cement mixture is injected into a rectangular hollow mold through a discharge pipe at the bottom of the mixing tank due to gravity. After a certain period of curing, the solidified body in the hollow mold is cut into insulation bricks of required specifications. During the mixing process of the cement mixture, the cement slurry will be contaminated on the surface of the tank wall of the mixing tank. Since it does not move with the mixing of the cement mixture, it will agglomerate on the inner surface of the tank wall of the mixing tank. The agglomerate will fall into the cement mixture due to the increase of its own weight, affecting the quality of the final core injection molding of the cement mixture. In order to avoid the generation of tank wall agglomerations, a new type of core injection device for cement foam exterior wall insulation bricks is needed. Utility Model Content
