Feeding cart of magnesium smelting operation unit

Abstract

The invention belongs to the technical field of magnesium smelting reduction process operation equipment, and particularly relates to a feeding cart of a magnesium smelting operation unit used for vertical-type tank thermal storage reduction furnaces. The feeding cart of the magnesium smelting operation unit is convenient to use, capable of performing feeding quantitatively, large in capacity, capable of ensuring that spherical magnesium ore is complete, low in offcut rate and high in product quality, and the feeding cart of the magnesium smelting operation unit is used for the vertical-type tank thermal storage reduction furnaces. The feeding cart of the magnesium smelting operation unit comprises a walking mechanism, wherein a rack is arranged on the walking mechanism, and a barrel-shaped feeding bin is arranged on the rack. The feeding cart of the magnesium smelting operation unit is structurally characterized in that a discharging bin with the top being an opening and the bottom being a discharging opening is arranged in the feeding bin, the discharging bin is arranged on the rack through a lifting mechanism, a lower frame is arranged at the bottom of the rack, a quantitative stock bin is arranged on the lower frame, and a vibrating material screening box is arranged between the quantitative stock bin and the discharging opening of the discharging bin through flexible connection. .

Description

technical field [0001] The invention belongs to the technical field of magnesium smelting reduction process operating equipment, and more specifically, the invention relates to a charging vehicle for a special operating unit of a magnesium smelting vertical tank heat storage reduction furnace. Background technique [0002] Magnesium has become the most concerned and most promising lightweight green structural material and functional material due to its excellent performance and abundant resources. It has extremely important application value and It has broad application prospects and is known as "the green engineering material of the 21st century". my country is extremely rich in magnesium ore resources. After decades of development, my country's primary magnesium output ranks first in the world, and has become a major producer and exporter of magnesium, forming a competitive and sustainable development advantage industry. Magnesium plays an extremely important role and inf...

Problems solved by technology

[0008] The opening of the vertical tank regenerative reduction furnace is upward; when working, there needs to be a gap between the magnesium ore materials so that the magnesium vapor can flow upward smoothly, which requires the magnesium ore materials to be in a relatively complete spherical shape; however, for one-time charging It can meet the use of multiple reduction tanks, and the required silo has a large capacity and a deep depth; in this way, the magnesium ore falling from a high place is easy to break; if there are too many broken materials, when the magnesium is reduced to magnesium vapor, the magnesium ore The gap between them is reduced, and the magnesium vapor cannot effectively crystallize in the crystallizer, which seriously affects the production of magnesium

[0009] There are generally two types of existing silos with buffer devices. One is to set staggered slanting plates in the silo, and the granular materials will drop layer by layer along the slanting plates during the descent process to play a buffering role; the other is to The spiral plate is set in the silo, and the spiral plate guides the granular materials to the bottom of the silo; although these two types of silos can also play a certain buffering role, their main application Smaller particles, or buffering of powdery materials; while the vertical tank regenerative reduction furnace needs larger particles of spherical magnesium ore; therefore, there will be a large number of gaps under the inclined plate or spiral plate , wasting a lot of storage space; in this way, in order to increase the storage capacity, a larger silo is required, which makes the silo heavy and occupies a large area

Moreover, the spherical material is easy to roll, and does not necessarily move along the guide of the inclined plate or the spiral plate; therefore, the above-mentioned two existing silos with buffer devices are not suitable for large-particle spherical magnesium ore, and it is easy to cause local Blockage, reducing the reliability and availability of blanking
