Description
Technical field
The present invention relates to the rotary kiln field producing lime, particularly relate to frictional drive lime rotary kiln in a kind of self-regulated.
Background technology
Rotary kiln lime calcining has had the history of more than 300 years, and in China from since the technology and equipment of 20 century 70 equipment Imported From German EMH Companies and the U.S., shaft preheater, shaft cooler are promoted widely.At present, on-stream and newly-built lime rotary kiln many employings shaft preheater and cooler technology, the preheating of lime stone and the decomposition reaction of a part are all carried out in preheater, and the length of rotary kiln is shortened further.The draw ratio of modern lime rotary kiln is all within 1:15.Therefore newly-designed lime rotary kiln is all the two groups of support roller supportings adopted, and this makes to adopt friction mode to carry out transmitting torque between support roller and rolling ring becomes possibility.
The quality evaluating the design of rotary kiln mainly contain easy to operate, maintenance cost is low, also has cost of use (mainly consuming energy low) these three.Modern lime rotary kiln output is increasing, and diameter is also increasing.Such as, the lime rotary kiln diameter of 1200 tons/day reaches 5.2m.Due to above factor, the contact stress between the support roller of lime rotary kiln and rolling ring is also increasing.The drawback of fixed like this support roller technology is also just more and more obvious.The axis corresponding to two groups of support rollers in fixed wheel holding mechanism and the axis between cylinder of rotary kiln be by supporting-roller shaft bearing after jackscrew adjust, one is only had in theory to heart position.Be difficult to accomplish that two axis are completely parallel in practical operation, even if it is parallel that two axis are adjusted when cold conditions, but the temperature of the position when hot corresponding to two groups of support roller supportings is different, and Temperature Difference Ratio is larger, the diameter of kiln is also very large simultaneously, there is larger thermal expansion amount poor, this just cause the drive current of now a lot of kiln kiln when cold conditions and theoretical value very close, drive current aborning and theoretical value far short of what is expected, mainly because hot time two axis no longer parallel.
Some design now, artificial suitably reduces the height of high temperature section supporting arrangement according to calculating, and when making hot, two axial lines is tending towards theoretical value, does like this and can play a role.But when the damage of refractory material in kiln, in kiln, the change of each several part temperature directly can have influence on this theoretical value calculated, and then has influence on the effect of artificial adjustment.The axis of the determined axis of support roller group and kiln cylinder body misaligns the impact caused and mainly contains: one is that kiln operates and needs larger power, causes driving power to consume excessive, and the operating cost of kiln increases; Two is be no longer linear contact between support roller with rolling ring, and the service life of support roller and rolling ring reduces, once need maintenance, kiln cooling is very large to the damage of refractory material in kiln, each of which increases the maintenance cost of kiln.
Summary of the invention
The object of this invention is to provide frictional drive lime rotary kiln in a kind of self-regulated, with self-aligning function, driving torque is transmitted by the frictional force between support roller and rolling ring, reduce because of rotary kiln axis and the not parallel and contact stress that produces of the determined axis of support roller group, extend the service life of kiln body rolling ring, reduce maintenance cost and the operating cost of rotary kiln.
For achieving the above object, the present invention is achieved through the following technical solutions:
Frictional drive lime rotary kiln in self-regulated, comprise active roller station group, driven support roller group, kiln body and rolling ring, active roller station group and driven support roller group is respectively equipped with under kiln body, wherein active roller station group matches with the rolling ring being positioned at kiln body feed side, it is identical that described driven support roller group comprises structure, two riding wheel apparatus be arranged symmetrically with, the opposite side of two riding wheel apparatus is hinged with the two ends of central substrate respectively, the opposite side bottom part down of two riding wheel apparatus is respectively equipped with hinge beam, resilient rubbber cushion is provided with between riding wheel apparatus and hinge beam, when driven support roller group contacts with rolling ring, central substrate is in quick condition.
Described resilient rubbber cushion is two pieces of two ends being separately positioned on a hinge beam.
The bottom of described hinge beam and the base of kiln body hinged.
The bottom of described riding wheel apparatus is provided with the positive stop of restriction hinge beam amplitude of fluctuation.
Also two riding wheel apparatus identical with driven support roller group are provided with in described active roller station group, direct-connected on one group of riding wheel apparatus wherein have a planet cycloid speed reducer, described planet cycloid speed reducer is furnished with self adaptation base and is fixed on fixing basis, the primary input end of planet cycloid speed reducer is connected with mair motor through Hooks coupling universal coupling, being connected with dish kiln motor through freewheel clutch from input of planet cycloid speed reducer.
Compared with prior art, the invention has the beneficial effects as follows:
1) make the determined axis of support roller group and the automatic centering of kiln body rolling ring axis, avoid the excessive wear of support roller and rolling ring, improve the service life of support roller and rolling ring.2) improve rotary kiln quantity-produced ability, greatly reduce the maintenance cost of kiln body.3) decrease driving power during rotary kiln running, thus reduce the operating cost of rotary kiln.4) eliminate the parts such as bull gear, pinion, the parts of rotary kiln are reduced further, makes transmission mechanism compacter, decrease maintenance workload, decrease the construction volume of concrete foundation simultaneously, thus be minimized cost of investment.
