Description
Technical field
The utility model relates to a kind of rotary kiln, particularly a kind of preheater of 600 tons of rotary kilns.
Background technology
It is 12 that the general general preheater of 600 tons of rotary kilns of metallurgy industry is cut somebody's hair, the life-time service process is circulating for singly pushing away, if the time of setting is 30 seconds/bar, added up stroke 12 seconds, push away a defective material and needed for 42 seconds, after waiting for other 11 push rod operation one circles (462 seconds), if preheater temperature height, the probability that forms fluffy material becomes bigger.Using the result is owing to the cycle is long, the easy fluffy material of preheater.And because of the inequality of being heated, the preheater effect worse and worse.
The utility model content
The utility model proposes a kind of preheater of rotary kiln, solved deficiency of the prior art, by increasing cutting somebody's hair of preheater, and carry out pusher simultaneously by many covers material-pulling device, under the situation of pusher time decreased, just can reach design output like this, simultaneously the well-ventilated of preheater pusher, pre-heat effect is better, reduce fluffy material probability, and can control the thermally equivalent of material to greatest extent, improved the benefit of production efficiency and sale; Simultaneously, stablize thermal regulation, reduced staff's labour intensity.
The technical solution of the utility model is achieved in that a kind of preheater of rotary kiln, comprise former feed bin and the heat exchange chamber below it of being located at the top, the bottom of described heat exchange chamber is provided with many cover material-pulling devices, comprise that also the control material-pulling device carries out the pusher controller of pusher, described pusher controller can be controlled two cover material-pulling devices at least and carry out pusher simultaneously, the bottom of described former feed bin is connected with a plurality of filling tubes, heat exchange chamber is all inserted in the bottom of each filling tube, the top of described heat exchange chamber is provided with flue dust outlet pipe corresponding with the filling tube position and that quantity is identical, and be equipped with the venting variable valve at each flue dust outlet pipe, the quantity of described material-pulling device is 14-18, and the bottom of described heat exchange chamber has discharge port.
Further, described former feed bin is three stage structure, comprises epimere, stage casing and hypomere, and its epimere is taper, and the stage casing is cylindricality, and hypomere is back taper.
Further, the quantity of described filling tube, flue dust outlet, venting variable valve and material-pulling device is identical, and is even numbers.
Further, the quantity of described filling tube, flue dust outlet, venting variable valve and material-pulling device is 16.
Further, the bottom outside of described heat exchange chamber also is provided with bracing or strutting arrangement.
Further, described bracing or strutting arrangement is steelframe or the concrete column that is uniformly distributed in the heat exchange chamber bottom outside.
Compared with prior art, the beneficial effects of the utility model are: after adopting said structure, the material-pulling device of preheater is increased to 14-18 by original 12, and overlap material-pulling devices by at least two and carry out pusher simultaneously, under the situation of pusher time decreased, just can reach design output like this, the well-ventilated of while preheater pusher, pre-heat effect is better, reduced fluffy material probability, She Ji many venting variable valve free adjustment as required simultaneously can be controlled the thermally equivalent of material to greatest extent.When finding that preheater has fluffy material phenomenon, the venting variable valve that fluffy material level can be put cuts out, and the time has been grown, and just can make fluffy material collapse voluntarily.Prolong the time of maintenance at interval, improved the benefit of production efficiency and sale; Simultaneously, stablize thermal regulation, reduced staff's labour intensity.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is one of them embodiment of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, former feed bin; 11, epimere; 12, stage casing; 13, hypomere; 2, heat exchange chamber; 3, material-pulling device; 4, filling tube; 5, flue dust outlet pipe; 6, venting variable valve; 7, bracing or strutting arrangement; 8, discharge port.
Embodiment
Below the technical scheme in the utility model is clearly and completely described, obviously, described embodiment only is several embodiment wherein of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of preheater of rotary kiln comprises former feed bin 1 and the heat exchange chamber 2 below it of being located at the top, described former feed bin 1 is three stage structure, comprises epimere 11, stage casing 12 and hypomere 13, and its epimere 11 is taper, stage casing 12 is cylindricality, and hypomere 13 is back taper.The bottom of described heat exchange chamber 2 is provided with many cover material-pulling devices 3, comprise that also control material-pulling device 3 carries out the pusher controller of pusher, described pusher controller can be controlled two cover material-pulling devices 3 at least and carry out pusher simultaneously, the bottom of described former feed bin 1 is connected with a plurality of filling tubes 4, heat exchange chamber 2 is all inserted in the bottom of each filling tube 4, the top of described heat exchange chamber 2 is provided with flue dust outlet pipe 5 corresponding with filling tube 4 positions and that quantity is identical, and be equipped with venting variable valve 6 at each flue dust outlet pipe 5, the quantity of described material-pulling device 3 is 14-18, the bottom of described heat exchange chamber 2 has discharge port 8, and the bottom outside of described heat exchange chamber 2 also is provided with bracing or strutting arrangement 7.In the present embodiment, the quantity of described filling tube 4, flue dust outlet, venting variable valve 6 and material-pulling device 3 is 16, and described bracing or strutting arrangement 7 is for being uniformly distributed in the concrete column of heat exchange chamber 2 bottom outside.
