Abstract
The utility model discloses a kind of lime stone automatic stirring materials rotary kiln, including kiln hood, kiln body and the kiln tail being sequentially connected, kiln body inwall are uniformly fixed with some switch-plates；Switch-plate Spiral distribution is in kiln body inwall.The utility model sets the switch-plate of spiral in kiln body inwall, powder is in the case where the rotation of kiln body drives and stirred, make behavior of the material in stove change into rolling+pulsation by traditional rolling+slip to roll, solve the problems, such as solid accumulation irregular, that granularity is small and influence heat exchange；And the firing time of material is shortened, the production capacity of rotary kiln is added, reduces energy consumption.
Description
Technical field：
A kind of lime stone automatic stirring materials rotary kiln is the utility model is related to, belongs to field of metallurgical equipment.
Background technology：
Lime is one of primary raw material of calcium carbide production.Lime calcining mainly uses shaft furnace (sleeve kiln, Maers Kiln) at present
And calcined by rotary kiln, it is very strict to raw material limestone granularity requirements, and wherein shaft furnace requires that raw material granularity is more than 40-80mm, returns
Rotary kiln requires that raw material granularity is more than 30-50mm, and granularity is less than 25mm lime stone due to its poor air permeability, and shaft furnace and revolution
The inner wall smooth of kiln, therefore rollover effect is poor in the shaft furnace and rotary kiln of routine, causes raw limestone curing irregular, limitation
Its use in shaft furnace and rotary kiln.
But below 25mm building stones are inevitably generated less than in limestone mining process, it is existing broken
System can not just ensure the shape of small powder on the premise of aniseed shape is ensured, cause TV manufacturing enterprise limestone powder not
It is disconnected to overstock, cause occupancy and the wasting of resources in a large amount of places.
Utility model content：
In order to solve the above problems, the purpose of this utility model is to provide a kind of lime that can handle limestone powder
Stone automatic stirring materials rotary kiln.
The purpose of this utility model is implemented by following technical scheme, a kind of lime stone automatic stirring materials rotary kiln, it include according to
Kiln hood, kiln body and the kiln tail of secondary connection, the kiln body inwall are uniformly fixed with some switch-plates；The switch-plate Spiral distribution
In the kiln body inwall.
Further, the pitch of the switch-plate is identical with the length of the kiln body.
The advantages of the utility model：The utility model sets the switch-plate of spiral, rotation of the powder in kiln body in kiln body inwall
Turn to drive and stir down, behavior of the material in stove is changed into rolling+pulsation by traditional rolling+slip and roll, solve
Irregularly, the small solid accumulation of granularity and influence heat exchange the problem of；And the firing time of material is shortened, add rotary kiln
Production capacity, reduce energy consumption.
Brief description of the drawings：
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of lime stone automatic stirring materials rotary structure schematic diagram of embodiment 1；
Fig. 2 is Fig. 1 A-A views.
In figure：Kiln hood 1, kiln body 2, kiln tail 3, switch-plate 4.
Embodiment：
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment 1：
A kind of lime stone automatic stirring materials rotary kiln, it includes the kiln hood 1, kiln body 2 and kiln tail 3 being sequentially connected, the inwall of kiln body 2
Uniformly it is fixed with some switch-plates 4, switch-plate 4 preferably 8；The Spiral distribution of switch-plate 4 is in the inwall of kiln body 2.The spiral shell of switch-plate 4
Away from identical with the length of kiln body 2.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
Claims (2)
