Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a tuyer structure for a tempering furnace. Background Technology

[0002] In the glass processing industry, tempering furnaces are the core equipment for glass strengthening. By heating the glass to its softening point and then rapidly and uniformly cooling it, compressive stress is formed on the glass surface and tensile stress is formed inside, thereby significantly improving the mechanical strength, impact resistance and thermal stability of the glass, meeting the demand for high-strength glass in multiple industries such as construction, automobiles, and electronics.

[0003] In the tempering furnace process, the efficiency and effectiveness of the cooling stage directly determine the quality of tempered glass. The duct structure, as a core component for conveying and distributing cooling airflow, has a crucial impact on cooling efficiency, energy consumption, and the quality of the finished glass product. Currently, most tempering furnace ducts adopt a square structure, which reveals significant limitations in practical applications: Firstly, the square duct's airflow channel has corners and right-angle transitions, leading to turbulence and energy loss during airflow, making it difficult to form a stable, high-speed airflow stream. This reduces the contact efficiency between the cooling airflow and the high-temperature glass, prolonging the cooling time and making it difficult to ensure uniform cooling across different areas of the glass, affecting the stress distribution of the tempered glass. Secondly, due to the significant energy loss in the airflow, more energy is required to drive the cooling fan to achieve the desired cooling effect, resulting in low energy utilization, which is inconsistent with the current trend of energy conservation and emission reduction in industrial production.

[0004] Therefore, in response to the shortcomings of existing square air vent structures in terms of cooling efficiency and energy saving, a new type of air vent structure has been developed that can optimize airflow, reduce energy loss, and improve cooling effect. This has become a key direction for the improvement and upgrading of tempering furnace equipment and is of great significance for promoting efficient and energy-saving production in the glass processing industry.

[0027] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0028] Example 1

[0029] See Figures 1 to 5 A tuyer structure for a tempering furnace includes an air inlet 1, an acceleration zone 3, and an air outlet 5. The acceleration zone 3 is connected to the output end of the air inlet 1, and the input end of the air outlet 5 is connected to the acceleration zone 3. Both the air inlet 1 and the air outlet 5 are reducing pipes. The output port diameter of the air inlet 1 is smaller than the input port diameter, and the output port diameter of the air outlet 5 is larger than the input port diameter. The maximum diameter of the air inlet 1 is larger than the maximum diameter of the air outlet 5, and the acceleration zone 3 is spherical.

[0030] A first transition air duct 2 is provided at the connection between the air inlet 1 and the acceleration zone 3.

[0031] The longitudinal section of the first transition duct 2 is arc-shaped on both sides, and the radius of curvature of the arc is 1 / 5 to 1 / 3 of the maximum diameter of the air inlet 1.

[0032] A second transition air duct 4 is provided at the connection between the air outlet 5 and the acceleration zone 3.

[0033] The longitudinal section of the second transition duct 4 is arc-shaped on both sides, and the radius of curvature of the arc is 1 / 5 to 1 / 3 of the maximum diameter of the air inlet 1.

[0034] The inner surfaces of the air inlet 1, the acceleration zone 3, and the air outlet 5 are provided with a heat insulation layer 6.

[0035] The outer surfaces of the air inlet 1, acceleration zone 3 and air outlet 5 are provided with sound insulation layers 7.

[0036] The maximum diameter of the air inlet 1 is not less than twice the maximum diameter of the air outlet 5.

[0037] A flange 101 is provided at the end of the air inlet 1 that is away from the acceleration zone 3.

[0038] Working principle

[0039] The overall structure follows a "wide → narrow → wide" variable diameter logic, precisely utilizing Bernoulli's principle (when fluid velocity increases, pressure decreases; when velocity decreases, pressure increases) to accelerate airflow. Inlet 1 is a reducer with a large (wide) inlet and a small (narrow) outlet. After entering inlet 1, the airflow narrows due to channel contraction, reducing the cross-sectional area. At the same flow rate, the cross-sectional area is inversely proportional to the velocity, significantly increasing the velocity. This results in increased kinetic energy and decreased pressure. Entering the spherical acceleration zone 3, the spherical space provides a buffer area for uniform diffusion and secondary acceleration, allowing the high-speed airflow to form a stable turbulent field and preventing sudden changes in local velocity. The airflow then enters outlet 5, which is a reducer with a narrow inlet and a wide outlet (narrow → wide). Channel expansion further regulates velocity and pressure, utilizing the kinetic energy conversion generated by velocity changes to reduce the energy consumption of the power unit.

[0040] Meanwhile, the maximum diameter of the air inlet 1 is not less than twice the maximum diameter of the air outlet 5. By increasing the size difference between the air inlet 1 and the air outlet 5, the "wide → narrow → wide" diameter change effect is enhanced, making the velocity change of the airflow during the contraction and expansion process more significant, further improving acceleration efficiency, reducing the power demand of the power unit, and achieving energy saving.

[0041] The first transition duct 2 at the connection between the air inlet 1 and the acceleration zone 3, and the second transition duct 4 at the connection between the air outlet 5 and the acceleration zone 3, both adopt a design with arc-shaped sides on both sides of the longitudinal section, and the radius of curvature of the arc is 1 / 5 to 1 / 3 of the corresponding maximum diameter (maximum diameter of air inlet 1 and maximum diameter of air outlet 5). This arc-shaped transition structure can avoid airflow impact and vortex caused by right-angle or acute-angle transitions, and reduce wind resistance loss: when the airflow enters the acceleration zone 3 from the air inlet 1 or enters the air outlet 5 from the acceleration zone 3, the arc-shaped surface can guide the airflow to smoothly turn, reduce the frictional resistance between the airflow and the channel wall, keep the airflow in a laminar state, ensure stable increase in flow velocity, avoid energy loss caused by turbulence, and further improve acceleration efficiency.

[0042] The heat insulation layer 6 on the inner surface of the air inlet 1, acceleration zone 3, and air outlet 5 can reduce the heat exchange between the external environment and the inside of the air duct. When the tempering furnace is working, the airflow delivered by the air outlet needs to have a stable cooling capacity. The heat insulation layer 6 can prevent the high temperature inside the furnace from being conducted into the air duct, avoid the airflow from absorbing heat and causing the temperature to rise, ensure that the cooling airflow is kept at a low temperature, and improve the cooling effect of the tempered glass.

[0043] When airflow moves at high speed within the duct, it rubs and impacts against the duct walls, generating turbulent noise. Simultaneously, mechanical noise is transmitted when the air inlet 1 is connected to power devices such as air pumps. The sound insulation layer 7 (usually sound-absorbing cotton, damping materials, etc.) on the outer surface of the air outlet 5 can absorb sound wave vibrations and block noise transmission, reducing noise pollution during operation and improving the working environment.

[0044] A flange 101 is installed at the end of the air inlet 1 away from the acceleration zone 3. It can be precisely connected to the flange interface of power devices such as air pumps and fans through bolts to ensure the connection is sealed and prevent air leakage. At the same time, the detachable flange connection facilitates the later equipment maintenance and component replacement, improving installation and operation and maintenance efficiency.

[0045] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Based on the technical solution of the present utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the present utility model.
