Lifting type filling bin

Abstract

The invention belongs to the technical field of magnesium smelting reduction technological operation equipment, and relates to a lifting type filling bin, in particular to a filling bin of an operating unit special for a vertical tank thermal storage reduction furnace for magnesium smelting. The filling bin comprises a cylindrical upper bin arranged on a rack, and is structurally characterized in that a lower bin is arranged in the upper bin, wherein an opening is formed in the top of the lower bin, and a discharge port is formed in the bottom of the lower bin; the lower bin is arranged on the rack through a lifting mechanism.

Description

technical field [0001] The invention belongs to the technical field of magnesium smelting reduction process operating equipment, more specifically, the invention relates to a filling bin of a special operating unit for 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 influence on...

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
