AI Technical Summary
Technical Problem
During the production of calcium carbide, the electrode ribs are prone to slide off the contact element, resulting in unstable electric furnace current.
Method used
A contact element for calcium carbide production is designed, using a wedge-shaped block as a contact head, and a plurality of step through holes are provided on the contact block to place the disc spring, locking the left and right elements by bolts, thereby providing a stable locking force.
Benefits of technology
By reducing the area of the contact electrode ribs and utilizing the elasticity of the disc spring, the electrode ribs are ensured not easily slide off the contact element, maintaining the stability of the current, and being able to transmit large currents.

Abstract
The utility model belongs to the technical field of contact elements for calcium carbide production, and mainly relates to a contact element for calcium carbide production, which comprises a left element and a right element, the left element and the right element are symmetrically arranged on two sides of an electrode rib sheet so as to clamp the electrode rib sheet, and the left element and the right element respectively comprise a contact block. The contact block is provided with a contact projection, and the contact projection is provided with a contact head used for clamping an electrode rib sheet. A wedge-shaped block is arranged on a contact bulge and is provided with a wedge-shaped surface, and the wedge-shaped surface is inclined, so that the wedge-shaped block is provided with a bulge part which is in contact with an electrode rib sheet, that is, after a left element and a right element are locked on the electrode rib sheet under the condition that the contact area of the electrode rib sheet is reduced and a locking force is kept unchanged, the left element and the right element are locked on the electrode rib sheet; and the electrode rib sheet is not easy to slide off from the contact element.
