Mechanical transmission submerged arc furnace distributing device

Abstract

The invention discloses a mechanical transmission submerged arc furnace distributing device. The mechanical transmission submerged arc furnace distributing device comprises a planetary gear motor arranged on a water-cooling center throat pipe, a rotation support arranged on the water-cooling center throat pipe, a rotary sleeve connected with the outer ring of the rotation support, and a water-cooling chute, wherein an output shaft of the planetary gear motor is provided with a pinion, and the planetary gear motor drives the pinion to rotate; the inner ring of the rotation support is close to the water-cooling center throat pipe, a gear on the outer ring of the rotation support is engaged with the pinion, and the pinion can drive the rotation support to rotate through the outer ring; the rotary sleeve is connected with the outer ring of the rotation support, and the pinion of the planetary gear motor rotates the rotation support to drive the rotary sleeve to rotate; and the water-cooling chute is connected with the planetary gear motor through a connection rod of a lead screw elevator, and the planetary gear motor drives the water-cooling chute to swing through the connection rod ofthe lead screw elevator. The mechanical transmission submerged arc furnace distributing device can distribute materials onto different ring faces, automatic feeding of any point in a submerged arc furnace is achieved, materials are distributed more evenly, enlargement of the submerged arc furnace is facilitated, and inner consumption of the submerged arc furnace is reduced.

Description

technical field [0001] The invention relates to a submerged arc furnace charging device, in particular to a mechanically driven submerged arc furnace distributor. Background technique [0002] At present, most of the domestic submerged arc furnace feeding equipment is tube type and rocker type (manually operated rocker), such as figure 1 with figure 2 shown. The tube-type feeding method can only be fed at fixed points, and the covering surface is uneven. In addition, the space of the hood is limited, and the number of tubes to be laid is also limited. The discharge port of the feed pipe is mostly water-cooled, and it is also very easy to burst and leak water, causing accident hazards and affecting the operation rate of the equipment; burn out. [0003] Although the rocker type feeding can distribute the material to different positions of the submerged arc furnace, the positions of the α angle and β angle of the chute are judged and positioned by the workers based on exp...

The tube-type feeding method can only be fed at fixed points, and the covering material surface is uneven. In addition, the space of the hood is limited, and the number of tubes to be laid is also limited.

[0003] Although the rocker type feeding can distribute the material to different positions of the submerged arc furnace, the positions of the α angle and β angle of the chute are judged and positioned by the workers based on their experience. The workers first open the material distribution door, visually check the material surface, and manually control the chute by feeling. The α angle (the inclination angle of the distribution chute) and the β angle (the circumferential angle of the distribution chute) are used to realize the distribution. The experience of each worker is different, and the uniformity of the distribution cannot be guaranteed.
