 Metal structure shell drying kiln

Modern metal shell wood drying rooms are almost all made of aluminum alloy materials. They have a beautiful appearance and can be used to build various large drying rooms in the open air.

The common method of metal shell is to make the boat-shaped foundation and ground with concrete first, and then install the frame prefabricated with aluminum alloy profiles on the foundation. Then install the siding and equipment. At present, there are two methods of making domestic siding. One is to use high temperature resistant polyurethane foam to prefabricate the wall panels according to standard specifications. The inner wall is made of flat aluminum plate, the outer wall is made of corrugated aluminum plate or color-plastic steel plate, the middle is made of high-temperature-resistant polyurethane foam, and there are mosaic grooves on both sides. When installing, you only need to cut the length properly with a saw, and the wall board or roof board is connected with aluminum alloy beams or pressure strips with screws or added to the frame. Prefabricated siding can also be used directly to assemble gates.Another method is to directly fill and assemble on site. The inner and outer wall panels used are basically the same as the prefabricated wall panels. First, the inner wall panels are loaded on the frame, then the rock wool board insulation layer is installed, and finally the corrugated panels are installed. The inner wall panels cannot be connected by rivets, and aluminum alloy beams or pressure strips should also be clamped to the frame with screws to reduce rivet holes. After the wall panels are installed, all seams on the inner surface of the shell are sealed with high temperature resistant silicone rubber, which has good elasticity, aging resistance and strong adhesion at -50-150 °C. Among the two wallboard manufacturing methods, the prefabricated wallboard is easy to install, is conducive to the sealing of the shell, and has a good thermal insulation effect, but the cost is high. This method first originated from abroad, and most of the shells of imported drying chambers have this structure. The on-site filling structure is actually a reform measure adopted by domestic enterprises to reduce the cost of the shell, but the construction is more complicated and the construction period is long. If the inner wall can be welded as a whole, the sealing effect is more ideal.

All components and connectors of the metal shell are made of aluminum alloy or stainless steel. Therefore, it has good corrosion resistance and long service life, but it is more expensive. It is suitable for large-capacity, multi-chamber conjoined use, and can be constructed in a large-scale production with three conjoined left, right and rear sides.
