Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a metal connecting pipe for high-temperature furnaces and kilns with high efficiency in heat dissipation. Background Technology

[0002] In the metallurgical, ceramics, and building materials industries, high-temperature furnaces and kilns are core production equipment that operate under extreme high-temperature conditions for extended periods. Their associated metal connecting pipes must simultaneously fulfill the core functions of high-temperature medium transmission and system sealing. Traditional metal connecting pipes have several drawbacks. Under high-temperature conditions, the pipe body and interface are prone to severe thermal stress due to differences in thermal expansion coefficients, leading to interface cracking and medium leakage. This not only affects the normal operation of the furnace and kiln but may also cause safety hazards. Furthermore, the pipe body often adopts a solid, thick-walled structure, which has a large heat storage capacity but low heat dissipation efficiency. Heat accumulation can accelerate the creep and oxidation aging of the pipe material, shortening its service life.

[0003] Currently, the drawbacks of traditional metal connecting pipes are becoming increasingly apparent in the operation of high-temperature furnaces. At the connection points, the installation pipe and the connecting pipe often crack due to thermal stress impact. The main reason is that the thickness at the connection point is not specifically increased, which cannot effectively resist thermal stress, leading to sealing failure and a significant increase in the risk of media leakage. At the same time, most connecting pipes adopt an integral thick-wall design to ensure strength, making it difficult for heat to be quickly conducted to the heat dissipation components, resulting in low heat dissipation efficiency. Heat accumulation accelerates material aging and shortens service life. The outer ring at the top of the connecting pipe is mostly a rigid connection, which cannot adapt to deformation when facing thermal expansion and contraction, and is prone to structural loosening or even falling off. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency heat dissipation metal connecting pipe for high-temperature furnaces, aiming to improve the problem of poor pipe wall stability during installation in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency heat dissipation metal connecting pipe for high-temperature furnaces, including an installation pipe, an installation mechanism at the bottom of the installation pipe for connection, and a heat-conducting mechanism on the outer wall of the installation pipe for heat dissipation.

[0006] The installation mechanism includes a connecting pipe, the outer wall of which is located at the bottom of the installation pipe, a flange at the top of which is provided, a thin-walled section on the outer wall of the installation pipe, an outer ring at the top of the installation pipe, a stabilizing component fixedly connected to the outer wall of the outer ring, a buffer component fixedly connected to the inner wall of the outer ring, and a thermal insulation component fixedly connected to the bottom outer wall of the installation pipe.

[0007] As a further description of the above technical solution:

[0008] The heat conduction mechanism includes a clamping ring, the outer wall of which is disposed on a thin-walled outer wall, a heat exchange layer is fixedly connected to the bottom of the outer wall of the clamping ring, a fixing ring is fixedly connected to the bottom of the outer wall of the heat exchange layer, a stabilizing component is fixedly connected to the outer wall of the fixing ring, an exchange component is fixedly connected to the outer wall of the heat exchange layer, and a fixing component is fixedly connected to the top of the clamping ring.

[0009] As a further description of the above technical solution:

[0010] The insulation component includes an insulation board, the outer wall of which is disposed at the bottom of the outer wall of the installation pipe, and a fixing column is fixedly connected to the outer wall of the insulation board.

[0011] As a further description of the above technical solution:

[0012] The stabilizing component includes a connecting plate, the outer wall of which is fixedly connected to the outer wall of the outer ring, and a fixing post 2 is fixedly connected to the outer wall of the connecting plate.

[0013] As a further description of the above technical solution:

[0014] The buffer assembly includes a connecting block, the outer wall of which is fixedly connected to the outer wall of the mounting tube, and a shrink plate is slidably connected to the outer wall of the connecting block.

[0015] As a further description of the above technical solution:

[0016] The stabilizing component includes a base, the outer wall of which is fixed to the bottom of a fixing ring, and a compression column is fixedly connected to the inner wall of the base.

[0017] As a further description of the above technical solution:

[0018] The heat exchange assembly includes heat exchange fins, the outer wall of which is fixed to the outer wall of the heat exchange layer, and an L-shaped plate is fixedly connected to the outer wall of the heat exchange fins.

[0019] As a further description of the above technical solution:

[0020] The fixing component includes a positioning block, the outer wall of which is fixed to a clamping ring, and a layer is fixedly connected to the top outer wall of the positioning block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by increasing the thickness at the connection between the installation pipe and the connecting pipe, the strength of the interface structure can be improved, effectively resisting the impact of thermal stress on the interface under high temperature environment and avoiding interface cracking; at the same time, the shrinkage plate on the inner wall of the outer ring at the top of the installation pipe cooperates with the sliding connecting block to form a flexible connection structure, which can adapt to the deformation of the installation pipe during thermal expansion and contraction, ensuring the stability of the installation and avoiding structural damage caused by deformation of the rigid connection, and adapting to the working conditions of frequent temperature fluctuations in high-temperature furnaces and kilns.

[0023] 2. In this utility model, the heat exchange layer is snapped onto the thin wall, and the outer wall is connected to the heat exchange fins, which greatly increases the heat dissipation area and enhances the efficiency of convection and radiation heat dissipation. The heat conduction mechanism is fixed by the base of the fixing ring and the pressing column, and the clamping ring layer is snapped onto the positioning block of the installation tube. This not only ensures the tight assembly of the heat conduction mechanism and the installation tube, avoiding structural loosening at high temperatures and affecting heat dissipation, but also simplifies the installation process and improves the assembly stability and maintenance convenience.
