Abstract

The invention discloses a bell-type movable full fiber resistance furnace, which comprises a furnace cover, a lift mechanism for moving the furnace cover, a furnace base for supporting the furnace cover, a furnace frame for installing the lift mechanism and a transmission mechanism connected with the furnace frame; the furnace cover comprises an internal furnace cover and an external furnace cover; the internal furnace cover is in a hollow structure; heating elements are arranged between the internal furnace cover and the external furnace cover; and heating bricks are arranged on the furnace base and spliced to form a plurality of spaced concentric rings. By adopting a furnace body with a particular structure, the heating area can be increased, the heating space can be reduced, the uniformity of the furnace temperature is improved, the speed of temperature rise is increased, and the electric energy is saved; by adopting the arc heating bricks, the bearing can be ensured, the number of the heating elements on the furnace bottom can be increased, and the comprehensive uniformity of a heated workpiece is improved; and by adopting the lift mechanism to move the furnace cover, the working intensity of operators can be reduced, the production rate is greatly improved, and the personnel safety is simultaneously ensured.

Description

technical field [0001] The invention relates to a heating device, in particular to a movable bell-jar type all-fiber resistance furnace. Background technique [0002] In recent years, with the state's support for wind power and other industries, it is conducive to the accelerated development of the wind power equipment industry. In this way, the requirements for the heat treatment equipment required for the ring parts of the wind power equipment are also getting higher and higher. Traditional trolley furnaces or pit furnaces have disadvantages such as many heating dark areas, high energy consumption, and troublesome hoisting during heat treatment, resulting in low production efficiency and low quality of workpieces. In addition, the furnace is like a chimney, and the hot air flow rises up, causing the temperature at the bottom of the furnace to be low. The upper opening of the furnace is often low due to poor sealing and insulation, and the temperature in the middle is high...
