Description

Technical Field

[0001] The utility model relates to the technical field of air valve regulation, in particular to an annealing furnace air valve regulation device. Background Art

[0002] An annealing furnace is a device widely used in the field of metal processing, mainly used to remove the heat treatment hardening layer on metal workpieces. This device can change the physical and chemical properties of metals through heating and cooling processes. In the metal processing process, such as forging, welding, and heat treatment, metals usually go through a series of heat treatment steps, which will cause the metals to harden. The hardened metals have higher strength and hardness, but in some application scenarios, it is necessary to anneal the metals to eliminate or reduce their hardness and improve their plasticity.

[0003] The annealing furnace air valve is a device used to control the gas flow in a high-temperature furnace, which plays a key role in the industrial production process. It helps to increase the furnace temperature, shorten the heating time, and reduce energy consumption.

[0004] Chinese Patent Publication No.: CN215172305U published "An Improved Air Valve Regulation Device", which relates to an improved air valve regulation device. In the existing air valve regulation device, due to the existence of convex, concave, or hollow structures, the air resistance increases, and it is necessary to increase the corresponding exhaust power. An improved air valve regulation device includes a wind blade. The wind blade includes a main body and connecting parts at both ends. The main body is a smooth and flat structure, and the main body and the connecting parts are an integral structure; detachable first and second knobs are provided at both ends of the wind blade, a first sealing ring is provided on the first knob, and a second sealing ring is provided on the second knob. The structure of the present utility model is reasonable. The main body of the wind blade is a smooth and flat structure, which greatly reduces the air resistance, the overall weight is reduced, and the service life is long.

[0005] When the existing technology is in use, although the air resistance is greatly reduced and the overall weight is lighter, the stability of the existing device is poor. When in use, the wind blade is easily blown by the exhausted gas, resulting in the deflection of its angle, which in turn affects the accuracy of controlling the exhausted air volume. At the same time, when annealing in an annealing furnace, flue gas will be generated in the furnace, and the existing device lacks a filtering device for flue gas, resulting in the easy dispersion of dust and other impurities in the flue gas into the air, causing environmental pollution. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide an annealing furnace air valve regulating device, which solves the problems in the background technology that the stability of the existing device is poor, the air blades are easily blown by the discharged gas during use, resulting in the deflection of their angles, and then affecting the accuracy of the control of the discharged air volume.
