Description

Technical Field

[0001] This utility model relates to the field of drying oven sealing technology, and specifically to a top sealing device for a drying oven. Background Technology

[0002] In the production process of engineering machinery parts, the overflow of hot air during drying has always been a common problem faced by accumulating chain conveyor drying ovens and hoist-type conveyor drying ovens. To effectively address this challenge, an innovative solution was adopted: adding a double-layer rubber plate seal at the top of the drying oven and at the gap where the conveyor boom passes through. This sealing structure is securely connected by C-shaped steel and bolts, forming a two-layer protective system.

[0003] However, in practical applications, we have discovered several problems with this sealing structure: First, if the rubber sheet is too thin, it will be too soft, which will seriously affect the sealing effect; second, if the rubber sheet is exposed to high temperature for a long time, it is very easy to solidify and flake off, which will not only reduce the sealing performance, but may also have an adverse effect on the product quality; finally, the service life of the rubber sheet is relatively short, and it needs to be replaced every 3 to 4 months, which is both time-consuming and laborious. Utility Model Content

[0004] The main objective of this invention is to provide a top sealing device for a drying oven, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A top sealing device for a drying oven includes a first sealing element and a second sealing element. The first sealing element and the second sealing element have the same structure and are symmetrically designed.

[0007] The first sealing element includes a C-shaped steel structure. The side wall of the C-shaped steel structure has a cavity, and the inner wall of the C-shaped steel structure is provided with an aluminum silicate cotton layer. The end face of the C-shaped steel structure has multiple insertion holes, and an L-shaped fastening rod is inserted and connected into the insertion holes. The lower end of the L-shaped fastening rod has a threaded part, and a first fastening head and a second fastening head are installed at the threaded part. The C-shaped steel structure is sealed to the top of the drying oven through the L-shaped fastening rod, the threaded part, and the fastening head.

[0008] In an optional embodiment of this application, multiple insertion holes are equidistantly distributed on a C-shaped steel structure, and the insertion holes are designed as waist holes with arc-shaped edges.

[0009] In an optional embodiment of this application, the cross-section of the C-shaped steel structure is designed in the shape of a "C", and the shape of the C-shaped steel structure is consistent with that of the aluminum silicate cotton layer. The aluminum silicate cotton layer is attached to the inner wall of the cavity of the C-shaped steel structure, and the end face of the aluminum silicate cotton layer is provided with holes aligned with the insertion holes. The base layer of the aluminum silicate cotton layer is an aluminum silicate cotton core.

[0010] In an optional embodiment of this application, the cross-section of the L-shaped fastening rod is designed in the shape of an "L" and both ends of the L-shaped fastening rod are designed in a spherical shape. The threaded part is located on the lower end of the L-shaped fastening rod and extends to the upper end of the L-shaped fastening rod. The upper end of the L-shaped fastening rod is provided with a lateral hole, which is a through hole. The edge of the lateral hole is designed in an arc shape, and the surface of the lateral hole and its surrounding area is roughened.

[0011] In an optional embodiment of this application, both the first fastening head and the second fastening head consist of an anti-slip washer and a fastening nut. The cross-section of the fastening nut is designed in a "T" shape, and the end of the fastening nut is connected to the anti-slip washer by an adhesive.

[0012] In an optional embodiment of this application, the first fastening head and the second fastening head are sleeved on the threaded portion and their positions are adjusted along the threaded portion to fix the C-shaped steel structure to the top of the drying oven.

[0013] In an optional embodiment of this application, the C-shaped steel structure, L-shaped fastening rod, and fastening head are all made of spring steel.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The aluminum silicate cotton layer has excellent high temperature resistance and heat insulation properties. When laid on the inner wall of the C-shaped steel structure, it can fit tightly and effectively insulate heat, further reducing heat loss and improving the safety and stability of the device.

[0016] The ingenious design of the L-shaped fastening rod, the first fastening head, and the second fastening head achieves a secure and sealed connection between the C-shaped steel structure and the top of the drying oven. The even distribution and balanced force of the fastening rods, along with the anti-slip washers and fastening nuts on the fastening heads, enhance the anti-slip effect, improve the reliability of the fastening, and ensure the stability and durability of the device during long-term operation.

[0017] The spring steel plate replaces the traditional rubber plate, reducing subsequent maintenance costs. For structures such as accumulating chain conveyors and hoist-type conveyors, this sealing method effectively improves the sealing effect and enhances product quality. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 4 As shown, a top sealing device for a drying oven is disclosed. The device consists of a first sealing element 1 and a second sealing element 2, both of which have identical structures and are symmetrically designed. This design ensures the uniformity and balance of the device, thereby effectively improving sealing performance.

[0025] The core structure of the first sealing element 1 is a C-shaped steel structure 11, with cavities 12 on its side walls for easy installation and fixing. A layer of aluminum silicate cotton 18 is laid on the inner wall of the C-shaped steel structure 11. This material has excellent high-temperature resistance and thermal insulation properties, effectively preventing heat loss. Furthermore, the end face of the C-shaped steel structure 11 is designed with multiple equidistant insertion holes 19. These insertion holes adopt a waist-shaped design with arc-shaped edges to reduce stress concentration and improve the stability and durability of the structure.

[0026] A structure with an L-shaped fastening rod 13 connected to it is inserted into the socket 19. The lower end of the L-shaped fastening rod 13 has a threaded part 15, through which the first fastening head 16 and the second fastening head 17 can be installed. This design achieves a reliable sealed connection between the C-shaped steel structure 11 and the top of the drying oven, ensuring the robustness and sealing of the device.

[0027] To further enhance the sealing effect, multiple insertion holes 19 are equidistantly distributed on the C-shaped steel structure 11, ensuring uniform distribution and balanced force of the fastening rods. The cross-section of the C-shaped steel structure 11 is "C"-shaped, perfectly matching the shape of the aluminum silicate cotton layer 18, allowing the aluminum silicate cotton layer 18 to fit tightly against the inner wall of the cavity 12 of the C-shaped steel structure 11. The end face of the aluminum silicate cotton layer 18 also has holes aligned with the insertion holes 19, facilitating the installation of the fastening rods.

[0028] The L-shaped fastening rod 13 has an "L"-shaped cross-section with spherical ends to reduce stress concentration and extend its service life. The threaded portion 15 is located on the lower end of the L-shaped fastening rod 13 and extends to the upper end, making fastening easier and more secure. The upper end of the L-shaped fastening rod 13 has a lateral hole 14, which is a through hole with an arc-shaped edge to reduce stress concentration. The hole and its surrounding surface are roughened to increase friction, thereby improving the fastening effect.

[0029] The first fastening head 16 and the second fastening head 17 are ingeniously designed. They consist of anti-slip washers and fastening nuts. The fastening nuts have a "T"-shaped cross-section, and the ends are connected to the anti-slip washers with adhesive. This design not only enhances the anti-slip effect but also improves the reliability of the fastening. The fastening heads are fitted onto the threaded portion 15 and can be adjusted along the threaded portion 15 to fix the C-shaped steel structure 11 to the top of the drying oven.

[0030] To ensure the strength and durability of the device, the C-shaped steel structure 11, the L-shaped fastening rod 13, and the fastening head are all made of spring steel. This material has good elasticity and strength, and can withstand the high temperature and pressure generated during the operation of the drying oven, ensuring the long-term stable operation of the device.

[0031] The aluminum silicate cotton layer 18 is tightly laid on the inner wall of the C-shaped steel structure 11, so that it fits the inner wall of the cavity 12. The L-shaped fastening rod 13 is inserted into the end face insertion hole 19 of the C-shaped steel structure 11, ensuring that its cross-section is "L"-shaped and both ends are spherical to reduce stress concentration. The first fastening head 16 and the second fastening head 17 are fitted onto the threaded portion 15 of the L-shaped fastening rod 13, and the position of the fastening head is adjusted to ensure that it can move along the threaded portion 15 for easy fixing.

[0032] Tighten the fastening head by threading the threaded portion 15 to ensure a sealed connection between the C-shaped steel structure 11 and the top of the drying oven. Ensure that the multiple insertion holes 19 are evenly distributed to achieve uniform distribution and force balance of the fastening rods. Check that all fasteners are secure and that there is no loosening or stress concentration. Ensure that the end holes of the aluminum silicate cotton layer 18 are aligned with the insertion holes 19 to facilitate the installation of the fastening rods. Conduct a preliminary test to ensure that the sealing effect of the top sealing device of the drying oven is good. Check for heat loss or air leakage, and adjust promptly if any problems are found. After confirming that the sealing effect is good, start the drying oven for normal operation. Regularly check the operating status and sealing effect of the equipment to ensure long-term stable operation.
