Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure steam curing, and more specifically to high-pressure steam curing equipment for self-insulating building blocks. Background Art

[0002] Self-insulating blocks refer to wall structures that can meet the current national and local energy-saving building standards without the use of internal and external wall insulation technology, and whose thermal indicators can meet the requirements of the national and local energy-saving building standards. Blocks need to be processed by high-pressure steam curing during the production process. The high-temperature and high-pressure steam treatment can evaporate the moisture in the blocks and promote the cement hydration reaction, thereby increasing the strength of the blocks, improving the insulation and sound insulation, fire resistance, water permeability resistance and frost resistance of the blocks, making them more in line with construction requirements.

[0003] In order to improve the curing efficiency, the existing high-pressure steaming equipment will distribute the blocks in layers to achieve batch steaming. However, the steam in the existing high-pressure steaming equipment is unevenly distributed, and the heating degree of each layer of blocks is different, which may cause some parts to be overheated while other parts are underheated. The blocks are deformed and cracked due to uneven expansion, and the product quality is unstable. Utility Model Content

[0004] The utility model aims to provide a high-pressure steam curing device for self-insulating building blocks, so that each layer of building blocks can be heated evenly, thus avoiding the problem of quality degradation caused by uneven heating of the building blocks.

[0007] Furthermore, the multi-layer placement rack includes multi-layer placement boards, and the placement boards are connected by support rods.

[0008] Furthermore, it also includes a steam central pipe, which is located in the autoclave body, passes through multiple layers of the placement plates, and is connected to the steam distribution plate, and a plurality of second steam nozzles are longitudinally installed on the steam central pipe.
