Description

Technical Field

[0001] This utility model relates to the field of flame heating equipment technology, and in particular to a crossbeam system for furnace tube support of a flame heating furnace. Background Technology

[0002] Currently, in existing flame-heated furnaces, the furnace tube support beams are typically directly exposed to high-temperature environments, requiring the use of high-temperature resistant alloy materials to ensure structural stability and safety. However, these high-temperature resistant materials are often expensive, and under prolonged exposure to high temperatures, the load-bearing capacity and service life of the beams may be affected. Furthermore, due to prolonged exposure to high temperatures, even with the use of high-temperature resistant materials, the load-bearing capacity and service life of the furnace tube support beams will gradually decrease, leading to frequent replacements and repairs. The high cost of high-temperature resistant materials and the complex maintenance work also impose a significant economic burden on enterprises.

[0003] Some companies also adopt external cooling measures, such as water spray cooling or forced air cooling. Although these methods solve some problems to a certain extent, they still have obvious drawbacks. Therefore, how to reduce material costs and maintenance difficulty while ensuring the thermal stability and load-bearing capacity of the furnace tube support beams has become an urgent technical problem to be solved. Utility Model Content

[0004] This application provides a crossbeam system for furnace tube support in a flame-heated furnace, which facilitates the improvement of the thermal stability of the crossbeam.

[0005] This application provides a crossbeam system for furnace tube support in a flame-heated furnace, which adopts the following technical solution:

[0006] A flame-heated furnace tube support beam system includes a furnace body, a furnace chamber inside the furnace body, a support beam arranged on the top of the furnace chamber, a furnace tube support suspended below the support beam, multiple furnace tubes installed on the furnace tube support, a ventilation duct arranged above the support beam, and an air supply system arranged inside the ventilation duct for supplying cooling air into the support beam.

[0007] By adopting the above technical solution, the flame-heated furnace tube support beam system designed in this utility model significantly improves the safety of the flame-heated furnace tube support beam system during use. Specifically, by setting ventilation ducts and air supply systems above the support beam, cooling air can be directly delivered into the interior of the support beam, thereby effectively reducing the working temperature of the beam and improving its thermal stability and load-bearing capacity. In addition, this design reduces reliance on expensive high-temperature resistant materials, lowers material costs, simplifies maintenance, and extends the service life of the beam.

[0008] Preferably, the support beam has an internal channel, the cross-section of which can be circular or rectangular to allow cooling air to circulate.

[0009] By adopting the above technical solution, the internal channel design of the support beam allows cooling air to effectively enter the beam, achieving uniform distribution and efficient heat dissipation. This not only improves the thermal stability of the beam and extends its service life, but also enhances the overall structural strength and load-bearing capacity of the beam, thereby ensuring the safe operation of the flame heating furnace.

[0010] Preferably, a blower is provided on one side of the ventilation duct, and the air outlet of the blower is connected to the ventilation duct for blowing cold air into the ventilation duct.

[0011] By adopting the above technical solution, the blower can effectively deliver cold air into the ventilation duct during use, ensuring a continuous supply of cooling air.

[0012] Preferably, the blower is equipped with a speed controller, which can adjust the flow rate of cooling air as needed.

[0013] By adopting the above technical solution, the blower is equipped with a speed controller, which can flexibly adjust the flow rate of cooling air according to actual needs. This design ensures that the cooling effect within the support beam is always optimal under different operating conditions, thereby improving the system's thermal stability and load-bearing capacity, and extending the service life of the support beam.

[0014] Preferably, the support beam is connected to the furnace chimney through a ventilation duct, and cold air is introduced by utilizing the negative pressure generated by the chimney.

[0015] By adopting the above technical solution, the support beam is connected to the furnace chimney during use. The negative pressure generated by the chimney introduces cold air, which not only effectively reduces the temperature of the beam and extends its service life, but also reduces the energy consumption of external power equipment and further saves operating costs.

[0016] Preferably, the ventilation duct is further provided with an air preheater system, which is used to provide cold air into the ventilation duct.

[0017] By adopting the above technical solution, the air preheater system can further improve cooling efficiency during use, ensuring that the temperature of the cold air entering the ventilation duct is lower and more uniform, thereby better protecting the support beam from high temperature.

[0018] Preferably, the internal channel of the support beam is provided with multiple guide plates to optimize the flow path of cooling air.

[0019] By adopting the above technical solution, multiple guide vanes can optimize the flow path of cooling air during use, ensuring that the cooling air is evenly distributed inside the entire support beam, improving cooling efficiency, and further enhancing the thermal stability and load-bearing capacity of the beam.

[0020] Preferably, the support beam is fixed to the top of the furnace chamber by a detachable connection and its surface is coated with a heat-insulating coating.

[0021] By adopting the above technical solution, the support beam is fixed by a detachable connection during use, which facilitates maintenance and replacement. At the same time, the heat insulation coating on its surface can further improve the high temperature resistance and thermal stability of the support beam and extend its service life.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0031] This utility model discloses a crossbeam system for furnace tube support in a flame-heated furnace, such as... Figures 1 to 3 As shown, the furnace includes a furnace body 1, within which a heating furnace chamber 2 is installed. A support beam 3 is arranged on top of the heating furnace chamber 2, and a furnace tube support 4 is suspended below the support beam 3. Multiple furnace tubes are installed on the furnace tube support 4. A ventilation duct 5 is arranged above the support beam 3, and an air supply system 6 is installed inside the ventilation duct 5 to deliver cooling air into the support beam 3. The support beam 3 has an internal channel. The cross-section of the internal channel can be circular to facilitate smoother airflow and reduce resistance, or it can be rectangular for easier processing and manufacturing. A circular cross-section makes it easier to achieve a uniform airflow distribution, while a rectangular cross-section is more suitable for complex structural layouts. The internal channels of the support beam 3 are equipped with multiple guide plates 10 to optimize the flow path of cooling air. The design of the guide plates 10 can guide the airflow along a specific direction, ensuring that the cooling air can evenly cover the entire support beam 3. The guide plates 10 can be made of thin metal sheets or other lightweight materials and are fixed to the internal wall of the support beam 3. The number and spacing of the guide plates 10 can be adjusted according to the actual cooling effect to achieve the best cooling effect. The support beam 3 is fixed to the top of the furnace chamber 2 of the heating furnace by a detachable connection. This installation method facilitates the replacement of support beams 3 that have been in use for a long time and also facilitates the maintenance of support beams 3. At the same time, the surface of the support beam 3 is coated with a heat-insulating coating to further improve its high-temperature resistance.

[0032] Cool air can be introduced into the ventilation duct 5 in three ways. First, a blower 7 installed on one side of the ventilation duct 5, with its outlet connected to the duct, can be used to blow cool air into it. The type of blower 7 can be adjusted according to actual needs; for example, a centrifugal blower 7 or an axial flow blower 7 can be selected. The centrifugal blower 7 is suitable for applications with high flow rates and low pressure, while the axial flow blower 7 is suitable for applications with low flow rates and high pressure. Both types of blowers 7 can effectively deliver cool air into the ventilation duct 5. The blower 7 is equipped with a speed controller to adjust the flow rate of cooling air as needed. Second, the support beam 3 can be connected to the furnace chimney 8 through the ventilation duct 5, utilizing the negative pressure generated by the chimney to introduce cool air. This method not only saves energy but also makes full use of existing factory facilities, reducing additional investment. The negative pressure generated by the chimney can be adjusted by controlling the height and diameter of the chimney to meet different cooling requirements. The third method is to use the air preheater system 9 installed inside the ventilation duct 5. The air preheater system 9 can store some cold air and send the cold air into the ventilation duct 5 when needed.

[0033] Working Principle: This utility model designs a furnace tube support beam system for a flame-heated furnace. By incorporating ventilation ducts 5 and an air supply system 6 within the support beam 3, cooling air is directly introduced into the beam, achieving a highly efficient cooling effect. This design not only improves the thermal stability and load-bearing capacity of the support beam 3 but also significantly reduces reliance on expensive high-temperature resistant materials, resulting in substantial economic and social benefits. Furthermore, through various optimization measures (such as the guide vane 10, speed controller, and air preheater), the system's reliability and energy efficiency ratio are further enhanced, comprehensively improving the overall working efficiency and safety of the flame-heated furnace.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
