Description
Technical field
The utility model relates to a kind of rotary kiln feed arrangement of Production By Sulfuric Acid Process titanium dioxide.
Background technology
In the sulfate process titanium dioxide production technology, metatitanic acid passes through the titanium dioxide product that calcined by rotary kiln just can obtain needs.The common feed arrangement of rotary kiln directly adopts feeding screw to realize.
The rotary kiln feed arrangement of current Production By Sulfuric Acid Process titanium dioxide is seen Fig. 1, comprise guide rail 11, described guide rail 11 is provided with bearing 1 by pulley, one end of described bearing 1 is provided with motor 14 and decelerator 2, the output of described decelerator 2 is provided with spiral shaft 10, described spiral shaft 10 is located on the bearing 1 by bearing bracket stand, one end of described spiral shaft 10 is provided with helical blade 7, described helical blade 7 arranged outside sleeves 6, also comprise a kiln hood 5, the below of described kiln hood 5 is provided with ash bin 9, described sleeve 6 passes from the sidewall of kiln hood 5, one end of described helical blade 7 is provided with material feeding box 4, and an end of this helical blade 7 stretches in the rotary kiln 8.
During work, motor drives helical blade by decelerator and spiral shaft and rotates, and will import to from the metatitanic acid that material feeding box is come in the rotary kiln, and along with the rotation and the calcining of rotary kiln, material " is walked about " forward and made the titanium dioxide finished product.When feeding screw driving, when stopping, utilizing pulley slippage on guide rail, feeding screw is put or is pulled out into rotary kiln.
There is following defective in existing feed arrangement: first, because the weight of helical blade and sleeve is heavier, in order to prevent that helical blade and sleeve from tilting to this end of rotary kiln, need make the spiral shaft long enough, like this, when maintenance feeding screw or parking feeding screw being pulled out rotary kiln will have sufficiently long guide rail, takes up an area of big, plant area will strengthen, and civil engineering cost increases.
Second, under the rotary kiln duty, kiln hood temperature has 400-500 ℃, the part sleeve of feeding screw in kiln and the influence of helical blade expanded by heating and material gravity, sleeve can saggingly contact with helical blade, causes helical blade wearing and tearing sleeve, cause the worn out damage of sleeve or come off, therefore, part is unsuitable long in the feeding screw kiln, and the feeding screw after the distortion is pulled out relatively difficulty of rotary kiln simultaneously.
The 3rd, as noted earlier, because the weight of helical blade and sleeve is heavier, in order to prevent that helical blade and sleeve from tilting to this end of rotary kiln, partial-length generally all can not be long in the feeding screw kiln, yet, feeding screw imports to the material in the rotary kiln, the kiln hood is static, rotary kiln rotates, along with the rotation meeting " batch turning " of rotary kiln is fallen in the kiln hood, there is the part material to leak out by sealing place between rotary kiln and the kiln hood, cause the waste of site environment pollution and material; Meanwhile, " batch turning " in the kiln hood falls into ash bin and forms " ash box material ", and part has increased the load of dust remove of exhaust treatment system along with calcining tail gas enters exhaust treatment system; In addition " ash box material " under 400-500 ℃ of condition, material physics and chemical property change for a long time, if reuse " ash box material " can influence the quality of titanium dioxide product.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, maintenance convenience, the rotary kiln feed arrangement of the Production By Sulfuric Acid Process titanium dioxide of long service life.
For realizing this purpose, the utility model is solved by following technical proposals: a kind of rotary kiln feed arrangement of Production By Sulfuric Acid Process titanium dioxide, comprise guide rail, described guide rail is provided with bearing by pulley, one end of described bearing is provided with motor and decelerator, the output of described decelerator is provided with spiral shaft, described spiral shaft is located on the bearing by bearing bracket stand, one end of described spiral shaft is provided with helical blade, described helical blade arranged outside sleeve, also comprise a kiln hood, the below of described kiln hood is provided with ash bin, described sleeve passes from the sidewall of kiln hood, and an end of described helical blade is provided with material feeding box, and an end of this helical blade stretches in the rotary kiln, it is characterized in that, the lateral wall of described sleeve is provided with stationary magazine creel, and the madial wall of this stationary magazine creel and the lateral wall of sleeve are gapped, and described stationary magazine creel is fixed on the kiln hood.
In the technique scheme, the lateral wall of described sleeve is provided with support post, and this support post is fixed in the upper end of ash bin.
The utility model compared with prior art, have following beneficial effect: 1) the utility model is because stationary pipes, eliminated the sleeve sagging that feeding screw part expanded by heating and material gravity effect in rotary kiln produce, so improve feeding screw service life greatly, and made maintenance workload reduce significantly.
2) the utility model increases support post on the basis of stationary pipes, so just can prevent that helical blade and sleeve from tilting to this end of rotary kiln, so just can reduce the worm drive shaft length, thereby the utility model floor space reduces, convenient in the feeding screw turnover kiln.
3) helical blade of the utility model in rotary kiln is longer, can prevent effectively that batch turning from falling in the kiln hood, thereby on-the-spot looks environment is thoroughly improved, and the exhaust system load of dust remove reduces greatly.Guaranteed that feeding screw moves continuously, this operation steady and continuous is produced, steady quality.
