Description

Technical Field

[0001] The utility model relates to the technical field of smoke channel control devices, in particular to a novel main smoke channel reversing mechanism. Background Art

[0002] In order to keep the melting furnace temperature constant, different heat storage chambers are switched to connect with the melting furnace during production. One side stores heat, and the other side is connected to the melting furnace to dissipate heat, so as to achieve stable and continuous production. In the flue, the smoke gate controls the flow of smoke and air to the heat storage chamber. The utility model patent with application number CN201921820277.3 proposes a glass melting furnace flue gate reversing connection mechanism to achieve synchronous reversing of the two gates. It connects the wire rope through two counter-rotating driven gears to switch the flue gas circulation duct. However, in this scheme, the gears are driven by a motor to rotate, and the flue switching response speed is slow. In addition, in actual applications, failures such as wire rope entanglement may occur, and the robustness is low. Utility Model Content
