Bottom device of electric calcining furnace

Abstract

The invention discloses a bottom device of an electric calcining furnace, and in particular relates to a furnace bottom fixing device and a material cooling device in a high-temperature electric calcining furnace. The bottom device of an electric calcining furnace comprises the following structure that a round main body structure is formed by a plurality of independent hollow fan-shaped cylinders; each hollow fan-shaped cylinder is divided into a plurality of cooling water cavities by longitudinal support plates; adjacent support plates are staggered; the lower part of each hollow fan-shaped cylinder is respectively provided with a water inlet tube and a water outlet tube; the lower ends of the adjacent hollow fan-shaped cylinders are connected by connecting plates; and a steel tube longitudinally penetrates through the hollow fan-shaped cylinder to be fixedly connected with the connecting plates by a fastening piece. The accident phenomenon that bottom electrodes collapse can be avoided by the bottom device, a fixed electrode holder and a cooled and calcined material become a whole, the height of the furnace body is lowered, production cost is lowered, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to a bottom device of an electric calciner, in particular to a bottom device for a high-temperature electric calciner. Background technique [0002] Calcining petroleum coke in a high-temperature electric calciner is a simple and effective method for desulfurization and reducing the resistivity of anthracite. At present, the widely used cathode is self-baked with electrode paste on a water-cooled support. Large air, poor operating environment, poor tamping effect, and the paste has a large porosity and low volume density. After a period of use, the bottom electrode is prone to collapse accidents, which seriously affects production. Moreover, the water-cooled bracket and The electrode paste has a large volume, occupying the effective height in the furnace and causing waste. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a bottom device of an electric calciner, th...
