[0001] The utility model relates to the technical field of high-temperature vertical furnaces, in particular to a lining structure for high-temperature vertical furnaces. Background Art

[0002] With the continuous development of industrial technology, high-temperature vertical furnaces, as important industrial equipment, are widely used in metallurgy, chemical industry and other fields. During the use of high-temperature vertical furnaces, the lining structure, as a key component in the furnace, is subjected to multiple factors such as high temperature and corrosion. Therefore, the performance and ease of disassembly and assembly of the lining structure directly affect the operating efficiency and service life of the high-temperature vertical furnace.

[0003] However, there are some common problems with the lining structure of high-temperature vertical furnaces on the market. In particular, the disassembly and assembly process of a single lining plate during assembly or maintenance is often cumbersome and difficult. Traditional lining structures are mostly cast or welded as a whole. Once damaged or in need of maintenance, the entire structure needs to be disassembled, which not only increases the difficulty and cost of maintenance, but also prolongs the maintenance cycle, affecting the normal operation of the high-temperature vertical furnace.

[0004] In addition, during the disassembly and assembly process of the traditional lining structure, the connection method between the lining plates is not flexible enough, and large mechanical equipment is often needed for assistance, which not only increases the operation risk, but also may cause damage to the lining structure. At the same time, for high-temperature vertical furnaces of certain special shapes or sizes, the traditional lining structure is even more difficult to meet their special needs.

[0005] Therefore, how to design a lining structure for a high-temperature vertical furnace that is easy to disassemble and assemble, solve the problem of the inconvenience of disassembling and assembling a single lining plate during assembly or maintenance, improve maintenance efficiency, and reduce maintenance costs has become an important issue that needs to be urgently solved in the current field of high-temperature vertical furnace technology.

[0008] A lining structure for a high-temperature vertical furnace, comprising a lining plate, a plurality of connecting seats are arranged on the right side wall of the lining plate, a disassembly mechanism is movably connected between the connecting seats, a plurality of sockets are arranged on the left side wall of the lining plate through a connecting block, one end of a spring is arranged on the inner side wall of the socket, a spring seat is arranged at the other end of the spring, a clamping ball is arranged on the outer side wall of the spring seat, and the outer end of the clamping ball extends out of the socket;

[0009] The utility model also comprises a keel, wherein a plug hole is provided on the right wall surface of the keel, and a slot is provided on the inner wall of the outer end of the plug hole.

[0010] Furthermore, the disassembly mechanism includes a connecting rod, a handle is welded on the outer wall of the connecting rod, screws are threadedly connected at both upper and lower ends of the connecting rod, a cylinder is interference fit connected to the outer wall of the screw, and the outer wall of the screw is threadedly connected to the connecting seat.

[0011] Furthermore, the inner end of the screw rod is located inside the connecting rod and is provided with a limit block.

[0012] Furthermore, four connecting seats are provided on the outer wall of each lining plate and are distributed at the four corners of the right side wall of the lining plate.

[0013] Furthermore, the jack and the socket are matched.

[0014] The beneficial effects of the utility model are:

[0015] Since a single liner can be disassembled, when a liner is damaged or worn, it can be replaced individually without disassembling the entire liner structure, which greatly reduces the difficulty and cost of maintenance and improves maintenance efficiency;

[0016] The detachable single liner design makes the installation and disassembly process easier, reduces the workload of the staff and improves work efficiency;

[0017] By replacing worn linings in time, further erosion and damage to the furnace body can be avoided, thus extending the service life of the furnace body;

[0018] The design of a single lining plate can be flexibly adjusted according to the temperature distribution and heating requirements in the furnace, optimizing the heating effect and ensuring the uniformity and stability of the temperature distribution in the furnace;

[0019] Since the maintenance and replacement process is simplified, the downtime caused by maintenance can be reduced and the overall operating efficiency of the high-temperature vertical furnace can be improved;

[0020] The utility model adopts a lining structure composed of a detachable single lining plate, which is not only convenient for maintenance and replacement and reduces labor, but also can extend the life of the furnace, improve the heating effect and stability, and reduce downtime, thereby improving the overall operating efficiency and economic benefits.
