Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy grain silo insulation technology, specifically a special insulation and sealing structure for doors and windows of sealed aluminum alloy grain silos. Background Technology
[0002] Grain warehouses are core facilities for storing food, existing throughout the history of agricultural development. Modern grain warehouses mostly use reinforced concrete or steel plate structures, equipped with temperature and humidity control, insect and mold prevention systems, and intelligent grain condition monitoring systems that can adjust the storage environment in real time. Current technologies focus on green and ecological grain storage, reducing the use of chemical agents through methods such as low-temperature controlled atmosphere and biological control, promoting sustainable development of warehousing. With the application of Internet of Things (IoT) technology, grain warehouses are evolving towards digitalization and intelligence, continuously safeguarding the lifeline of global food security.
[0003] Insulated doors and windows for grain warehouses are crucial components of grain depot construction. They not only provide insulation but also contribute significantly to rodent and insect control. Furthermore, effective ventilation through these doors and windows is a key characteristic. While airtight insulated doors and windows must possess reliable sealing, insulation, and flexible opening and closing, gaps often exist between the window and the mounting frame, allowing outside air to enter and resulting in poor sealing. Additionally, the sliding mechanism leads to dust accumulation between the window and the mounting frame over time, causing significant obstruction and reducing flexibility. Therefore, we propose a sealed aluminum alloy insulated door and window structure specifically designed for grain warehouses. Utility Model Content

[0012] Furthermore, connecting blocks 2 are fixedly connected between the two sliding columns located on the same connecting seat. The connecting blocks 2 are slidably connected to the inner side of the adjacent base, making the frame movement more stable.
