Production technique and apparatus of insulating brick

Abstract

The invention discloses a production technique and apparatus of an insulating brick. The production technique comprises the following steps: (1) putting a porous brick in a container, and filling polystyrene foaming particles into brick holes or grooves which need filling an insulating material in the porous brick, wherein the position of the porous brick put in the container satisfies the following conditions: A. the position filled with the polystyrene foaming particles in the porous brick is aligned with a first steam inlet in the container; B. a first steam outlet and the first steam inlet in the container are respectively arranged on both sides of the porous brick; (2) introducing steam to the first steam inlet, so that the steam is gradually transited from one side to the other side of the porous brick and discharged from the first steam outlet under the push action of gas pressure; and (3) stopping introducing the steam when the polystyrene foaming particles are connected and cured with the brick holes or grooves, and taking the formed insulating brick out of the container. The invention can prevent the porous brick from cracking and the like, and ensure the structural strength of the whole insulating brick.

Description

technical field [0001] The invention relates to the field of manufacturing composite thermal insulation building materials, and more specifically relates to a production process and equipment for thermal insulation bricks. Background technique [0002] Sintered bricks are being widely used due to their low cost, high strength and stable performance; however, they still have the disadvantage of poor thermal insulation performance. Therefore, how to enhance the thermal insulation performance of sintered bricks has become an urgent problem to be solved in the building materials industry. Such as Chinese patent announcement number CN2364110U, CN1821522A and CN1558055A all disclose the early solution respectively, and it basically all is to directly fill the thermal insulation material block or fill in the hole of the porous brick with adhesive glue and carry out compounding, promptly all exists Complicated structure and limited bonding strength and other defects. [0003] For t...
