Abstract

The invention relates to the technical field of calcium carbide submerged arc furnaces, and discloses a calcium carbide submerged arc furnace hole punching and plugging device and method. The device comprises a frame, an inclination angle adjusting mechanism, a hole punching mechanism and a hole plugging mechanism, wherein the inclination angle adjusting mechanism is mounted on the frame; the hole plugging mechanism and the hole punching mechanism are mounted on the inclination angle adjusting mechanism respectively; the inclination angle adjusting mechanism is used for adjusting the inclination angle of the hole punching mechanism and the hole plugging mechanism; the hole punching mechanism is used for punching the furnace hole of the calcium carbide submerged arc furnace; and the hole plugging mechanism is used for plugging the furnace hole. According to the invention, the mechanization of the calcium carbide submerged arc furnace hole punching and plugging device is realized by the hole punching mechanism and the hole plugging mechanism, the hurt to an operator caused by manual operation is avoided, the working efficiency is improved, the auxiliary working time of the submerged arc furnace is shortened, and the energy is saved; and moreover, the hole is plugged by calcium carbide particles, the service life of the furnace mouth is long, and the output is increased.

Description

technical field [0001] The invention relates to the technical field of calcium carbide submerged arc furnaces, in particular to a device and method for unblocking holes of calcium carbide submerged arc furnaces. Background technique [0002] Calcium carbide (calcium carbide) is an inorganic compound, generally a colorless crystal, and the industrial product is a gray-black block with a purple or gray cross-section. When it meets water, it reacts violently immediately to form acetylene and release heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas, and also used in organic synthesis, oxyacetylene welding, etc. [0003] Enterprises that produce calcium carbide all use calcium carbide submerged arc furnaces to produce the required calcium carbide through high-temperature smelting and catalysis processes. At present, the piercing of most calcium carbide submerged arc furnaces is done manually before being released from the fu...

AI Technical Summary

Problems solved by technology

This method brings the following hazards: 1. Manual operation is unsafe, and employees may be burned from time to time, and the manual blocking time is long and the efficiency is low, which leads to long auxiliary working hours of the submerged arc furnace and waste of energy; 2. Calcium carbide submerged arc furnace The temperature of the furnace mouth is high, and it is blocked by mud balls with water, which will cause premature damage to the furnace mouth, resulting in frequent replacement and maintenance of the furnace mouth, affecting production and output
