Iron chisel supply unit and blast furnace taphole drilling device

Abstract

The invention relates to an iron chisel supply unit. The iron chisel supply unit comprises chisel storage hoppers and iron chisel taking mechanisms, wherein the chisel storage hoppers comprises material bearing grooves with the wide upper portions and the narrow lower portions and discharging sections connected to the bottom ends of the material bearing grooves, discharging channels are formed in the discharging sections, and the width of the discharging channels is smaller than twice of the diameter of iron chisels; the iron chisel taking mechanisms are arranged at the outlet ends of the discharging channels. In addition, the invention further relates to a blast furnace taphole drilling device. The blast furnace taphole drilling device comprises a taphole drilling machine, the iron chisel supply unit and a chisel replacing unit used for installing the supplied iron chisels on the taphole drilling machine. According to the iron chisel supply unit and the blast furnace taphole drilling device, chisel storage hoppers are adopted for storing the iron chisels used for blast furnace production, the chisel storage hoppers are designed to comprise the material bearing grooves and the discharging sections, and the material bearing grooves are of the structure with the wide upper portion and the narrow lower portion, so that the storage amount of the iron chisels can be effectively increased; the width of the discharging channels is designed to be smaller than the twice of the diameter of the iron chisels, so that one-by-one discharging of the iron chisels can be ensured, and the chisel replacement operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of blast furnace production equipment, and in particular relates to a brazing supply unit and a blast furnace tapping device using the brazing supply unit. Background technique [0002] The tapping machine is used for tapping the blast furnace, and the brazing used is a vulnerable part. The used brazing needs to be replaced every time the tapping is opened, so the brazing is used in a large amount. At present, most iron and steel production enterprises use manual operation to replace the brazing. Since the brazing is changed manually, the storage and management of the brazing is also relatively chaotic, and they are often directly piled up on the open space next to the tapping machine. With the continuous advancement of the intelligent system in front of the furnace, some enterprises have adopted automatic brazing device to replace the braze; The location of the brazing needs to be fixed to facilitate the a...

Problems solved by technology

At present, most iron and steel production enterprises use manual operation to replace the brazing. Since the brazing is changed manually, the storage and management of the brazing is also relatively chaotic, and they are often stacked directly on the open space next to the tapping machine.

With the continuous advancement of the intelligent system in front of the furnace, some enterprises have adopted automatic brazing device to replace the braze; The location of the brazing needs to be fixed to facilitate the automatic brazing clamp to pick up the brazing; at present, the brazing storage frame is generally used for positioning and storing the brazing brazing, but on the existing brazing storage frame, in order to facilitate the automatic brazing changing clamp to pick up the brazing , the storage frame usually has only one layer, the capacity of the brazing is limited, the brazing is frequently replenished, and labor is time-consuming and labor-intensive. At the same time, the position of each brazing is different, and it is necessary to input the position of each brazing into the automatic changer brazing device, equipment operation complexity
