Problems solved by technology

[0003] 1. In the operation of manual eye opening, since the diameter of the steel bar used to poke the hole is only about 20mm, the hole that is poked out is small, it is difficult for the molten calcium carbide to pass through, and the furnace mouth is easy to block;
[0004] 2. When manually plugging furnace holes, the depth of the plugging is difficult to control
If the blockage is too deep, it will lead to eye-running accidents;
[0005] 3. The labor intensity of workers is high during manual operation, the working environment is harsh, and the manual participation time in the whole process is very long, there are great potential safety hazards, and various personal injuries are prone to occur
[0006] Although domestic submerged arc furnaces have also appeared in the furnace, most of them have unreasonable structures, inconvenient operation, and poor stability. They can only be used for general submerged arc furnaces, and cannot meet the requirements of calcium carbide furnaces

Abstract

The invention discloses an automatic discharge device of a calcium carbide furnace. The automatic discharge device comprises a cart mechanism, a tool rod locking mechanism, a working arm mechanism, a working arm pitching mechanism, a heat insulation protection system, a tool trolley, a trolley hydraulic station used for controlling a hydraulic device in the automatic discharge device of the calcium carbide furnace, and an automatic control system used to work together with all parts of the automatic discharge system of the calcium carbide furnace, wherein the tool rod locking mechanism and the working arm mechanism are connected together through a bolt, the working arm mechanism is fixed on the upper part of the cart mechanism through a bolt, two ends of the working arm pitching mechanism are respectively combined with the cart mechanism and the working arm mechanism through bolts, the heat insulation protection system is fixed on the front end of the cart mechanism, and the trolley hydraulic station is fixed on the back of the upper part of the cart mechanism. According to the automatic discharge device adopting the scheme, the whole automatic discharge device adopts hydraulic transmission and can be operated in a long distance, thus the manual operation of a hearth attendant is greatly reduced, the hearth attendant is prevented from being in a high-temperature environment for a long time, and the potential safety hazard is reduced.

Description

Technical field [0001] The invention belongs to smelting equipment, which is used to automatically discharge a calcium carbide furnace. Background technique [0002] The firing operation of the calcium carbide furnace (mainly opening, poke, and plugging) has always been manual operation. In the production of small calcium carbide furnaces in the past, the abnormality of the furnace door during manual operation has little effect on the production, but for large calcium carbide furnaces Furnace production is different. Manual operation often causes difficulties, and even accidents affect production. There are also the following shortcomings for manual production of large calcium carbide furnaces: [0003] 1. In the operation of artificial eye opening, since the diameter of the steel bar used to poke the eye is only about 20mm, the hole of the poke is small, it is difficult for the molten carbide to pass, and the furnace mouth is easy to block; [0004] 2. When manually plugging the f...
