For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of stone with preheating function
Ash rotary kiln, has pre-heat effect good, simple in construction, the feature that production cost is low.
For achieving the above object, this utility model is achieved through the following technical solutions: one has pre-
The lime rotary kiln of hot merit energy, is connected with the rotary kiln kiln body of inclination by kiln hood, and described rotary kiln is external
Being provided with the actuating device driving rotary kiln kiln body to rotate counterclockwise, the rear end of described rotary kiln kiln body connects kiln
Tail, described rotary kiln kiln body is provided with two sections of reducers at kiln tail, and lifting blade is arranged at bottom reducer
Inwall on, the revolution kiln body top inwall between described two sections of reducers is provided with the baffle plate downwardly extended,
The length of described baffle plate is more than or equal to 1/4th of rotary kiln kiln body diameter, less than or equal to rotary kiln
3/4ths of kiln body diameter.
Further illustrating, the described close reducer of kiln tail is 0.5-3 rice with the distance of kiln tail, described two
Distance between reducer is 1-3 rice.
Further illustrating, described rotary kiln kiln body is provided with multiple bearing support.
Further illustrating, described bearing support is 2-8.
Further illustrating, the angle of inclination of described rotary kiln kiln body is horizontal by 5-30 degree angle.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail, but does not limits
Make protection domain of the present utility model and range of application:
As it is shown in figure 1, a kind of lime rotary kiln with preheating function, by kiln hood 1 and the revolution tilted
Kiln kiln body 2 connects, and rotary kiln kiln body 2 is externally provided with the transmission dress driving rotary kiln kiln body 2 to rotate counterclockwise
Putting 3, the rear end of rotary kiln kiln body 2 connects kiln tail 8, and rotary kiln kiln body 2 is provided with two at kiln tail 8
Section reducer 6, is 0.5-3 rice near the reducer 6 of kiln tail 8 and the distance of kiln tail 8, two reducers
Distance between 6 is 1-3 rice.Lifting blade 4 is arranged on the inwall bottom reducer 6, two sections of reducings
Revolution kiln body 2 top inwall between section 6 is provided with the baffle plate 9 downwardly extended, baffle plate 9 and revolution kiln body
2 acute angle are 30 °-75 °, it is preferred that its angle be 45 ° optimal.The length of baffle plate 9 is more than
Or equal to 1/4th of rotary kiln kiln body 2 diameter, less than or equal to four points of rotary kiln kiln body 2 diameter
Three, such as, 1/4th of diameter of a length of kiln body of baffle plate 9,1/2nd, 3/4ths,
Preferably, the diameter of a length of kiln body of baffle plate 9 1/2nd and optimal.
The lime rotary kiln with preheating function of the present embodiment, refer to Fig. 1, in previous technique scheme
On the basis of concrete it may be that rotary kiln kiln body 2 is provided with multiple bearing support 7.Bearing support 7 can be
2,4,6,8.Bearing support 7 be for bearing and turning kiln kiln body 2 and the kliner coating of inside thereof, material 5,
Straight section material 8 etc., to ensure that rotary kiln kiln body 2 can rotate between the inverse time, the quantity of bearing support 7 can root
Depending on length according to rotary kiln kiln body 2.The angle of inclination of rotary kiln kiln body 2 is horizontal by 5-30
Degree angle.Kiln hood 1 is equipped with sealing ring, to prevent cold wind from entering.Kiln tail 8 is equipped with sealing ring, in case
Only cold wind enters.
This utility model has the operation principle of the lime rotary kiln of preheating function: limestone send here after from
Kiln tail 8 enters rotary kiln kiln body 2, and limestone is room temperature, in order to ensure the quality of Calx after calcining,
Limestone just can be calcined after must being preheating to uniform temperature.Distance due to kiln tail 8 to reducer 6
Comparatively short, when material 5 is sent to reducer 6, limestone temperature could not reach to calcine required temperature,
Must preheat.At reducer 6, material 5 is taken up along with the rotation of reducer 6, material
5 tops simultaneously being taken to reducer 6 by lifting blade 4, material 5 will constantly be raised, material 5
Sufficient and thermal current carries out heat exchange, acts at baffle plate 9, and second reducer 6 fallen by material 5
Bottom.Now material 5 is constantly taken up by lifting blade 4, the most sufficiently carries out heat hand over thermal current
Changing, when material 5 runs to burning zone, the temperature of material 5 has the most just reached the temperature needed for calcining.
So material 5 is just calcined, and the Calx after having calcined is discharged from kiln hood 1.Originally there is preheating function
Lime rotary kiln is simple, cost-effective, improve productivity ratio, and pre-heat effect is good.
Above content be combine that this utility model made by concrete preferred implementation the most in detail
Explanation, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model
For person of an ordinary skill in the technical field, make without departing from the concept of the premise utility
Some equivalents substitute or obvious modification, and performance or purposes are identical, all should be considered as belonging to this practicality new
The scope of patent protection that type is determined by the claims submitted to.
