Description

Split type rotary calciner

Technical field

The utility model relates to a kind of kiln, is specially a kind of split type rotary calciner.

Background technology

The a large amount of uses of calcining mineral is rotary kiln at present; the calcining of tradition rotary kiln has stable, a firm kliner coating; because it can protect refractory lining; reduce heat loss by the kiln body; the stable kliner coating of several cm thicks can not only make the wadding life-span prolong nearly 100%; and can also make kiln body temperature degree reduce several Baidu, this means and reduce heat loss up to 25%.But owing to many reasons, relatively poor such as ature of coal, ash and fugitive constituent are more, often cause the blocked up kliner coating of the local appearance of burning zone, people are referred to as it " ring formation ", it can hinder the operation of kiln considerably, the possibility that the existence of kiln body is burnt, the most serious is the cross section that it has strengthened the kiln body, thereby hindered the steady flow of going into kiln material and fuel gas, in case the kliner coating ring formation it just can not come off voluntarily, in order to handle their kilns of just having to periodically stop, rely on and manually repair, kiln body utilization rate is reduced greatly, and the production of this discontinuity has also greatly restricted the lifting of output, and wastes time and energy.For this reason, people prevent or handle always the method for the kliner coating ring formation that hinders operation in investigation, but effect is not very desirable.

Summary of the invention

The utility model need regularly stop kiln and carry out manual amendment in order to solve the existing easy ring formation of calcined by rotary kiln band liner, has problems such as kiln body utilization rate reduces greatly, output is reduced and waste time and energy, and a kind of split type rotary calciner is provided.

The utility model is to adopt following technical scheme to realize: split type rotary calciner, comprise by the preheating zone, burning zone and go out the kiln body that strip constitutes and be used to support the kiln body, and before being arranged on the kiln body, in, the kiln hood base at rear portion, base and kiln tail base in the kiln, be separately installed with bearing block on three bases, before the external wall of kiln, in, the rear portion is fixed with the roller strap that is supported on the bearing block, the external wall postmedian of kiln is provided with the master gear band by driving device controls, innovative point of the present utility model is to constitute the preheating zone of kiln body, burning zone is a split-type structural with going out strip, the burning zone two ends respectively with the preheating zone, go out to adopt between the strip movable sealing to connect, additional base is set up at two ends, burning zone below, on the additional base additional shaft bearing is installed, burning zone two ends outer wall is fixed with the additional roller strap that is supported on the additional shaft bearing.Above-mentioned burning zone and preheating zone, the movable sealing type of attachment that goes out between the strip are that those of ordinary skill in the art is easy to realize.The length of described burning zone can be determined according to the kind of calcining mineral and the factors such as entire length of kiln body.

In order further to optimize the structure of this rotary kiln, described at kiln hood one end additional base and the kiln hood base between set up the balance base, the trunnion shaft bearing is installed on the balance base, the external wall of the kiln corresponding with the trunnion shaft bearing is fixed with the balance roller strap, like this, after burning zone is removed, can guarantee to be positioned at kiln hood to go out strip firm; Balance gear band by driving device controls is set on the described balance base, this balance gear band is all consistent with the rotating speed and the direction of master gear band, can alleviate the load of master gear band and drive unit thereof, also alleviate the load of junctions, burning zone two ends greatly, guarantee the burning zone stability of rotation.

Compared with prior art, the utility model will very easily produce the burning zone and the preheating zone of blocked up kliner coating, going out strip makes split type, when the burning zone liner produces blocked up kliner coating, can be after stopping kiln, burning zone is pulled down, change one section standby burning zone then in a short period of time, and burning zone and preheating zone, go out to connect between the strip reliably, simple to operate, can shorten greatly and stop the kiln time, the basic nothing that realizes is intermittently produced, improve production efficiency greatly, guaranteed the optimal operational condition of rotary kiln " efficient; high-quality; low consumption ", had certain popularization value and use value.

Among the figure: the 1-preheating zone; The 2-burning zone; 3-goes out strip; 4-kiln hood base; Base in the 5-kiln; 6-kiln tail base; The 7-bearing block; The 8-roller strap; 9-master gear band; 10-adds base; 11-additional shaft bearing; 12-adds roller strap; 13-balance base; 14-trunnion shaft bearing; 15-balance roller strap; 16-balance gear band; The 17-connector.

The specific embodiment

Split type rotary calciner, as shown in Figure 1, comprise by preheating zone 1, burning zone 2 and go out the kiln body that strip 3 constitutes and be used to support the kiln body, and before being arranged on the kiln body, in, the kiln hood base 4 at rear portion, base 5 and kiln tail base 6 in the kiln, be separately installed with bearing block 7 on three bases, before the external wall of kiln, in, the rear portion is fixed with the roller strap 8 that is supported on the bearing block 7, the external wall postmedian of kiln is provided with the master gear band 9 by driving device controls, constitute the preheating zone 1 of kiln body, burning zone 2 is a split-type structural with going out strip 3, burning zone 2 two ends respectively with preheating zone 1, go out to adopt between the strip 3 movable sealing to connect, the connector 17 that is adopted can utilize existing multiple mechanical structure form to realize, additional base 10 is set up at two ends, burning zone 2 below, on the additional base 10 additional shaft bearing 11 is installed, burning zone 2 two ends outer walls are fixed with the additional roller strap 12 that is supported on the additional shaft bearing 11.Set up balance base 13 between the additional base 10 of kiln hood one end and kiln hood base 4, trunnion shaft bearing 14 is installed on the balance base 13, the kiln external wall corresponding with trunnion shaft bearing 14 is fixed with balance roller strap 15.Balance gear band 16 by driving device controls is set on the balance base 13.Above-mentioned drive unit can be made of buncher, reduction box etc. at least, rotates to drive master gear band or balance gear band, realizes the stable revolution of whole kiln body then.

This rotary kiln is in actual production, two the additional bases and the balance pony sill that rely on base, kiln tail base in kiln hood base, the kiln, are positioned at the burning zone below are located on the ground, rely on master gear band and balance gear band to drive whole kiln body rotation simultaneously by driving device controls, material is packed into by the kiln tail, successively through preheating zone, burning zone with after going out strip, by the kiln hood discharging.When rotary kiln running a period of time, after the burning zone liner forms blocked up kliner coating, open the connector at burning zone two ends, utilize equipment such as crane to remove burning zone, then that preheating is good standby burning zone (with consistent, the length unanimity of former kiln body burning zone structure) is erected on the additional base, close connector again, finished the rapid replacing of burning zone, guaranteed running without interruption of kiln body.
