Description

Technical Field

[0001] This utility model relates to the field of tunnel furnace connection technology, specifically to an elastic sealing connection structure for tunnel furnace equipment. Background Technology

[0002] A tunnel furnace is a continuous heating device with a tunnel-like shape. It is mainly used for heat treatment processes such as heating, drying, and curing in industrial production. The working process involves the product entering from one end of the tunnel furnace under the drive of a conveyor device, passing through the heating zone, and then exiting from the other end. The product completes the heat treatment while passing through the tunnel. The furnace body of a tunnel furnace is generally long and narrow, and the length of the furnace body can be customized according to production needs, ranging from a few meters to tens of meters. The width and height will also vary depending on the size of the products being processed and the required output.

[0003] However, the length of existing tunnel ovens is fixed. If the tunnel oven is too short, the product stays in the oven for a short time. For some products that require uniform heating, the heat may not be able to be fully conducted to all parts of the product, affecting the heating effect. When the tunnel oven is long, it occupies a lot of space and is not convenient to move. Summary of the Invention

[0004] The purpose of this utility model is to provide an elastic sealing connection structure for tunnel furnace equipment, which solves the problems of fixed length of existing tunnel furnaces, which affect the heating effect of products if the length of the tunnel furnace is too short, and the large space occupied by the tunnel furnace when it is too long, making it inconvenient to transport.

[0005] To achieve the above objectives, a flexible sealing connection structure for tunnel oven equipment is provided, comprising: an outer frame, with a support leg fixedly connected to the bottom of the outer frame, an inner frame fixedly connected to the inside of the outer frame, an inner liner fixedly connected to the inner side of the inner frame, and a sealing frame movably connected to the outer side of the inner frame. This facilitates the connection of multiple adjacent tunnel ovens, facilitates the heating of products, and, due to the small size of a single tunnel oven, facilitates the handling and transportation of the tunnel oven.

[0006] According to the elastic sealing connection structure of the tunnel furnace equipment, bolt fixing holes are provided on the side of the inner frame, and bolt connection holes are provided on both sides of the sealing frame. The position and number of the bolt fixing holes correspond to the position and number of the bolt connection holes, which facilitates the connection between the sealing frame and the outer frames of two adjacent tunnel furnaces, thereby facilitating the connection between two adjacent tunnel furnaces.

[0007] According to the elastic sealing connection structure of the tunnel furnace equipment, the bolt connection hole is provided with threads inside, and the bolt connection hole cooperates with the fixing bolt through the threads, which improves the stability of the connection between the sealing frame and the inner frame.

[0008] According to the elastic sealing connection structure of the tunnel furnace equipment, the sealing frame is welded from multiple layers of elastically deformable metal plates, which facilitates the expansion and contraction of the sealing frame.

[0009] According to the elastic sealing connection structure of the tunnel furnace equipment, both the inner liner and the inner frame are made of high-temperature resistant metal materials, which improves the service life of the inner liner and the inner frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The elastic sealing connection structure of this tunnel furnace equipment, by pre-reserving bolt fixing holes on the inner frame of the tunnel furnace and setting bolt connection holes on the sealing frame, can connect the sealing frame to the inner frame of two adjacent tunnel furnaces by inserting fixing bolts into the corresponding bolt fixing holes and bolt connection holes and tightening them, thereby facilitating the connection of two adjacent tunnel furnaces. Similarly, multiple tunnel furnaces can be connected into a longer tunnel furnace, which is convenient for product heating. At the same time, the connection method is simple and convenient, and easy to transport.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Bolt fixing holes 6 are provided on the side of the inner frame 3, and bolt connection holes 7 are provided on both sides of the sealing frame 5. The position and number of bolt fixing holes 6 correspond to the position and number of bolt connection holes 7. The sealing frame 5 can be installed on the inner frame 3 through the bolt connection holes 7 and the bolt fixing holes 6, which facilitates the connection of two adjacent inner frames 3. The bolt connection holes 7 are threaded inside, and the bolt connection holes 7 are engaged with the fixing bolts through the threads, which facilitates the tightening of the fixing bolts and strengthens the tightness of the connection between the sealing frame 5 and the inner frame 3. The sealing frame 5 is welded from multiple layers of elastically deformable metal plates. When the temperature of the inner liner 4 is high, the sealing frame 5 can freely expand and contract along the length of the tunnel furnace along with the inner frame 3. Both the inner liner 4 and the inner frame 3 are made of high-temperature resistant metal materials. The inner liner 4 and the inner frame 3 are usually subjected to high temperatures. Therefore, the high-temperature resistant materials can indirectly improve the service life of the inner liner 4 and the inner frame 3.

[0022] Working principle: When connecting two adjacent tunnel furnaces, align the bolt connection holes 7 on the sealing frame 5 with the bolt fixing holes 6 on the inner frame 3 of one of the tunnel furnaces, and insert the fixing bolts from one side of the inner frame 3 into the corresponding bolt fixing holes 6 and bolt connection holes 7, and tighten the fixing bolts to complete the connection between the sealing frame 5 and the inner frame 3. Similarly, align the bolt fixing holes 6 on the inner frame 3 of the other tunnel furnace with the bolt connection holes 7 on the other side of the sealing frame 5, and similarly insert the fixing bolts from one side of the inner frame 3 into the corresponding bolt fixing holes 6 and bolt connection holes 7, and tighten them to complete the connection between the two adjacent tunnel furnaces. Similarly, multiple tunnel furnaces can be connected according to the heating requirements of the product.
