Embodiment Construction

[0028] In various aluminum melting furnaces, holding furnaces or hybrid furnaces, as long as gas or liquid fuel is used as the heat supply source required by the furnace, no matter what kind of combustion method is used, all or part of the high-temperature flue gas will be emitted. In order to effectively control To reduce the emission of flue gas and improve the thermal efficiency of the furnace, it is necessary to use a smoke lock and effectively control the opening of the smoke lock in real time during the production process to adjust the internal pressure of the furnace. The invention provides a set of high-temperature-resistant air-cooled smoke gate device with complete structure and reasonable structure, which is installed on the flue and effectively participates in the control of the pressure in the furnace.

[0029] Such as Figure 1 to Figure 5 As shown, the high temperature resistant air-cooled smoke gate device of the present invention includes: driving cylinder 1, ...

Abstract

The invention provides a high-temperature resistant air cooling smoke gate device which comprises an air cooling gate plate, a gate plate seat, a blowing mechanism and a drive mechanism, wherein the gate plate is made of unformed refractory materials, and the inner part of the gate plate adopts a plurality of hollow steel pipes connected in parallel as a cooling air passage of the gate plate and an anchoring and supporting skeleton of the gate plate; outlets of the steel pipes are exposed outside the gate plate and connected with the blowing mechanism and the drive mechanism; and two bush roller chains drive the gate plate to participate in the pressure control of a furnace cavity by taking a drive cylinder as a power source. The high-temperature resistant air cooling smoke gate device hasthe advantages of novel design, reliable operation, convenient installation, low operation cost, easy maintenance and high operability and practicability and can be widely applied to various flame furnaces including an aluminum melting furnace, a heat preserving furnace or a mixing furnace in the electrolytic aluminum or aluminum processing industry.

Description

technical field [0001] The invention relates to a novel smoke gate device, in particular to a high-temperature-resistant air-cooled smoke gate device used on high-temperature exhaust pipes of aluminum smelting furnaces, holding furnaces and mixing furnaces. Background technique [0002] The smelting furnaces, holding furnaces and mixing furnaces used in the aluminum industry all have some high-temperature flue gases that are directly discharged. This requires the use of smoke gates. The smoke gates are installed on the exhaust flue, and the flue gas is discharged through the flue. The opening degree can adjust the smoke emission. [0003] The current general practice is that the gate is made of heat-resistant castings, the installation direction is perpendicular to the smoke exhaust direction of the flue, and the gate is driven by a motor, electric actuator or cylinder. In the production process of aluminum, refining agent and slagging agent need to be added, so a large amo...
