Technical Field

The invention belongs to the technical field of float glass production, and particularly relates to a reversing connection mechanism for a flue damper of a glass melting furnace.

Background

A float glass cross flame melting furnace for continuous production is characterized in that a regenerator structure is adopted to heat checker bricks in a regenerator by utilizing heat brought away by flue gas generated by combustion, combustion-supporting air for combustion is preheated before combustion by regularly absorbing and releasing heat of the checker bricks, the regenerators are distributed at two sides of the melting furnace, when air enters the regenerator at one side to absorb heat of the checker bricks, the regenerator at the other side discharges the flue gas to the outside of the furnace to heat the checker bricks, and in order to ensure continuous and stable production, when the checker bricks at one side release heat to heat the combustion-supporting air, the temperature is reduced, the requirement for heating the air can not be met, and when the temperature of the heat-accumulating checker bricks at the other side rises to a certain degree due to the absorption of the flue gas heat, the air and the flow direction of the flue. In order to realize timing reversing, the glass melting furnace generally uses flue reversing flashboards which are two types: a main flue reversing gate and a branch flue reversing gate mainly solve the problem of connection of the main flue reversing gates. The original reversing of the main flue is in signal connection with two independent control systems and two independent flashboard lifting mechanical transmission structures.

The structure form of the original reversing system flashboard is shown in figure 1, wherein a side flashboard A and a side flashboard B are two independent structure systems, the flashboard A and the flashboard B are both composed of a flashboard, a flashboard frame, an external steel shell, a transmission station (comprising a motor, a speed reducer, a master controller and the like), a counterweight trolley (a gear or a pulley, a chain or a steel wire rope) and the like, and the flashboard A and the flashboard B are respectively independent and symmetrically manufactured; and the gate plate A and the gate plate B realize reversing control through signal transmission instructions.

The original two flashboards are not connected with each other and are independent from each other, and the reversing is difficult to be synchronous.
