Structure of drill rod for calcium carbide furnace discharge conveyer

Abstract

The invention provides a structure of a drill rod for a calcium carbide furnace discharge conveyer. By the adoption of the structure, the drill rod can not be bent or is bent slightly during pulling, so that the feasibility of mechanical operation is improved, the service life of the drill rod is prolonged, and drill rod consumption is reduced. The structure mainly comprises a clamping head, a hollow steel tube and filler arranged in the hollow steel tube, wherein the clamping head is a clamping handle for mechanical operation, the hollow steel tube is connected with the clamping head, the whole hollow steel tube is filled with the filler which is in a solidified state, and the filler is a heat-insulating and heat-resisting material, can be solidified in the hollow steel tube and is high in rigidity and not prone to deformation. Due to the fact that the filler is not prone to deformation, the drill rod can not be bent or is bent slightly even if fusion loss occurs outside the drill rod.

Description

technical field [0001] The invention relates to tapping equipment for a metallurgical submerged arc furnace, in particular to a structural mode of a drill rod for a tapping machine of a calcium carbide furnace. Background technique [0002] Submerged arc furnace equipment technology has now entered the era of large-scale, airtight, highly automated, environmentally friendly and energy-saving. The development of new structures and new processes has been strengthened in the field of submerged arc furnace equipment at home and abroad, and new technologies have been continuously invested However, as a traditional high-energy-consuming and heavy-pollution industry, the technology of calcium carbide furnaces is still one of the most backward industries in China. At present, although some newly-built and renovated airtight calcium carbide furnaces in China are equipped with many advanced technologies, However, the process of firing the furnace is almost completely manual.

[0002] Submerged arc furnace equipment technology has now entered the era of large-scale, airtight, highly automated, environmentally friendly and energy-saving. The development of new structures and new processes has been strengthened in the field of submerged arc furnace equipment at home and abroad, and new technologies have been continuously invested However, as a traditional high-energy-consuming and heavy-pollution industry, the technology of calcium carbide furnaces is still one of the most backward industries in China. At present, although some newly-built and renovated airtight calcium carbide furnaces in China are equipped with many advanced technologies, However, the process of firing the furnace is almost completely manual. For the small non-airtight production in the past, the abnormality of the furnace door caused by manual operation has little impact on production. However, it is different for the production of large-scale closed calcium carbide furnaces. There will be difficulties, and even accidents will affect the production. Due to the non-standard operation of the furnace front workers such as burning through, piercing, plugging, and furnace eye maintenance, the furnace eye will continue to be on the stage, causing the bottom of the furnace to continue to rise, and the power consumption will be reduced. increase, there will still be furnace door, furnace wall, furnace lining burning phenomenon and eye-running accidents. In the production process of calcium carbide, the furnace is the most arduous process and the hardest work, especially when opening and blocking the operation. It is a dangerous link in production, so it is a trend to adopt mechanized operation. As a tool for poking holes and drawing fibers, the drill rod has to withstand high temperatures of about 2000C°, and it is often bent because of this, which brings difficulties to mechanized operations. Therefore, it is necessary to Develop a drill rod structure with no or less bending during fiber drawing to improve the feasibility of mechanized operations
