Description
Technical field
The utility model belongs to magnesium smelting reducing technological operation equipment technical field, and in particular, the utility model relates to the filling feed bin that a kind of magnesium is smelted vertical tank heat accumulation reducing furnace dedicated operations unit.
Background technology
Magnesium becomes green structural material of of greatest concern and the most potential lightweight and functional material with its good performance and rich in natural resources; Have extremely important using value and wide application prospect at automobile, electronics, electrical equipment, space flight and aviation and national defense and military industrial circle, be described as " the green engineering material of 21 century ".China's magnesium ore resources is very abundant, and through the development of decades, the former magnesium output of China occupies first place in the world, and has become the production and the big export country of magnesium, has formed competitive sustainable development strong industry.Magnesium metal has very important role and influence for Human's production life, so the improvement of magnesium metal smelting technology also has profound significance to the development of society, need constantly explore.
At present, the production of magnesium generally has dual mode: 1, electrolysis; 2, thermal reduction.
Electrolysis is because of its initial stage drops into bigger; And, comparatively harsh to specification requirement; Therefore, do not meet China's national situation, at home not by a large amount of uses.
And thermal reduction (also claiming ferrosilicon process) is through ferrosilicon the magnesia that from carbonate ore, produces through calcining to be carried out thermal reduction.Because this method has technological process and equipment is simpler, the small investment of founding the factory, production scale is flexible, the purity height of finished product magnesium, advantage such as technical difficulty is little, construction is easy; So it becomes the magnesium refining method that China generally adopts.
At present, the furnace binding of the magnesium-smelting silicothermic process of domestic use is: a plurality of reduction jars of horizontally set in body of heater.The reduction furnace of this horizontal type structure can't adopt plant equipment to operate on it after using; Must by manual work carry out the unloading lid, get crystallization magnesium of reduction furnace, jar in residue cleaning, add operations such as new magnesium ore deposit ball material, inefficiency; And, in the operating process, the workman all need bear give out in the reduction jar reach 1000 ℃ high temperature and a large amount of flue gases and dust; Operating environment is abominable, and labour intensity is big; In addition, owing to the body of heater volume is bigger, reduction jar quantity is more, therefore, needs a large amount of labours (body of heater with 48 reduction jars for producing 10,000 tons of crystallization magnesium, changes jar need of work workman 100 people, can accomplish in 1～2 hour), and production efficiency is also low.
For this reason, domestic factory has carried out the pilot production of vertical tank heat accumulation reducing furnace in Shanxi, and successful Application has also obtained considerable effect.The employing of vertical heat accumulation reducing furnace has reduced the energy consumption in the refining magnesium process, and topmost effect is to make refining magnesium process mechanismization become possibility with automated job.
The opening of vertical tank heat accumulation reducing furnace upwards; During work, needing has the space between the magnesium mineral aggregate, so that magnesium steam can make progress smoothly and flow, this just needs the magnesium mineral aggregate to be more complete spherical; But, can satisfy the use of a plurality of reduction jars in order once to feed, the bunker capacity that needs is big, and the degree of depth is dark; Like this, the magnesium mineral aggregate that is fallen by eminence is prone to break into pieces; If particle is too much, when magnesium-reduced became magnesium steam, reduced in the slit between the magnesium mineral aggregate, and magnesium steam can't have a strong impact on the production of magnesium effectively at the crystallizer intercrystalline.
Existing feed bin with buffer unit generally has two kinds, and a kind of is that staggered oblique cutting plate is set in feed bin, and granule materials successively descends along the oblique cutting plate in the decline process, plays cushioning effect; Another kind is that spiral plate is set in feed bin, and spiral plate plays the effect of guiding to granule materials, and granule materials is caused the feed bin bottom; Though the feed bin of these two kinds of forms also can play certain cushioning effect,, it is less that it is mainly used in particle, perhaps the buffering of powder material; And the vertical tank heat accumulation reducing furnace required be the bigger spherical magnesium mineral aggregate of particle; Therefore, below oblique cutting plate or spiral plate, can there be a large amount of spaces, have wasted a large amount of storing spaces; Like this,, then need bigger feed bin to realize, make feed bin heavy, take up an area of bigger in order to increase the storing amount.And spherical material is prone to roll, and might not move along the guiding of oblique cutting plate or spiral plate; Therefore, above-mentioned existing two kinds of feed bins with buffer unit are not suitable for the spherical magnesium mineral aggregate of bulky grain, and are prone to cause local the obstruction, reduce the reliability and the practicality of blanking.
