Description
Technical field
The invention belongs to magnesium smelting reducing technological operation equipment technical field, in particular, the present invention relates to the charging vehicle that a kind of magnesium is smelted vertical tank heat accumulation reducing furnace dedicated operations unit.
Background technology
The performance that magnesium is good with it and rich in natural resources become the green structural material of of greatest concern and the most potential lightweight and functional material, there is 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 " 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 production and the big export country of magnesium, has formed competitive sustainable development strong industry.Magnesium metal has very important role and influence for the mankind's productive life, so the improvement of magnesium metal smelting technique also has profound significance to social development, need to constantly explore.
At present, the production of magnesium generally has two kinds of modes: 1, electrolysis; 2, thermal reduction.
Electrolysis, because its initial stage drops into larger; And, comparatively harsh to specification requirement; Therefore, do not meet China's national situation, do not used in a large number at home.
And thermal reduction (also claiming ferrosilicon process) is, by ferrosilicon, the magnesia produced through calcining from carbonate ore is carried out to thermal reduction.Because this method has technological process and equipment is simpler, the small investment of founding the factory, production scale is flexible, and the purity of finished product magnesium is high, technical difficulty is little, build the advantages such as 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 tanks 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 be by manually carrying out unloading lid, get in Crystalline Magnesium, tank the residue cleaning, adding the operation such as new magnesium ore deposit ball material, inefficiency of reduction furnace; And, in operating process, the workman all needs to bear the high temperature of 1000 ℃ of reaching given out in the reduction tank, and a large amount of flue gases and dust; Operating environment is severe, and labour intensity is large; In addition, because the body of heater volume is larger, reduction tank quantity is more, therefore, needs a large amount of labours (body of heater with 48 reduction tanks, for producing 10,000 tons of Crystalline Magnesiums, change tank need of work workman 100 people, can complete in 1～2 hour), and production efficiency is also low.
For this reason, domestic pilot production of having carried out the vertical tank heat accumulation reducing furnace in Shanxi factory, successful Application has also obtained considerable effect.The employing of vertical heat accumulation reducing furnace, reduced the energy consumption in refining magnesium process, and topmost effect is to make to refine the magnesium process mechanism and automated job becomes possibility.
The opening upwards of vertical tank heat accumulation reducing furnace; During work, needing has space between the magnesium mineral aggregate, so that magnesium steam can make progress smoothly, flows, and this just needs the magnesium mineral aggregate to be more completely spherical; But, in order once to feed and can to meet the use of a plurality of reduction tanks, the bunker capacity needed is large, the degree of depth is dark; Like this, the magnesium mineral aggregate fallen by eminence is easily broken into pieces; If particle is too much, when magnesium-reduced becomes magnesium steam, reduce in the gap between the magnesium mineral aggregate, and magnesium steam can't, effectively at the crystallizer intercrystalline, have a strong impact on the production of magnesium.
The 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, granule materials is caused to bin bottom; Although 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, or the buffering of powder material; And the vertical tank heat accumulation reducing furnace required be the spherical magnesium mineral aggregate that particle is larger; 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, in order to increase the storing amount, need larger feed bin to realize, make the feed bin heaviness, take up an area larger.And spherical material easily rolls, might not be along the guiding movement 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 easily cause local the obstruction, reduce the dependable with function of blanking.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of easy to use, the energy dosing; Capacity is large, can guarantee that spherical magnesium mineral aggregate is complete, and the particle rate is low, the magnesium smelting operation unit charging vehicle of the vertical tank heat accumulation reducing furnace special use that product quality is high.
For realizing above-mentioned purpose of the present invention, the present invention adopts following technical scheme, the present invention includes walking mechanism, is provided with frame on walking mechanism, be provided with the feeding bin of tubular on frame, being provided with top in its structural feature feeding bin is the blanking bin that opening, bottom are discharging opening; Blanking bin is arranged on frame by elevating mechanism; The frame bottom is provided with underframe, is provided with quantitative feed bin on underframe; Quantitatively between the discharging opening of feed bin and blanking bin, be provided with the vibratory sieve hopper by being flexible coupling.
As a preferred embodiment of the present invention, the top of described vibratory sieve hopper one end is upper connector, and vibratory sieve hopper bottom is provided with screen cloth corresponding to an end of upper connector; The other end bottom of vibratory sieve hopper is provided with the lower connector that quantitatively feed bin is connected, and quantitatively the feed opening place of bin bottom is provided with open and close valve, and quantitatively the both sides of feed bin are provided with hangers.
