Abstract
The utility model discloses a rotary kiln, in particular to a lime rotary kiln used in production of aluminum oxide or cement, which is structurally characterized in that a kiln head is connected with an inclined rotary kiln body, a transmission device driving the kiln body in anticlockwise rotation is arranged outside the rotary kiln body, the rear end of the rotary kiln body is connected with a kiln tail, a reducing section is arranged on the rotary kiln body close to the kiln tail, and a lifting plate is disposed on the inner wall of the reducing section. The lime rotary kiln has the advantages of simple structure, energy conservation, saved cost, increased production efficiency and fine preheating effect.
Description
Technical field
The utility model relates to a kind of rotary kiln, particularly relates to the lime rotary kiln that uses in a kind of aluminum oxide or the manufacture of cement.
Background technology
In aluminum oxide and manufacture of cement, need produce lime with rotary kiln, Wingdale rotary kiln that can be present all is the outer preheater of kiln that adopts to the preheating of Wingdale, this structure exists following some shortcoming: on the one hand, the preheater cost of investment in limestone kiln is higher, particularly hydraulic efficiency system and hydraulic push rod are somewhat expensive, need again often to safeguard; On the other hand, because the preheater structure variety of issue occurs easily than complexity, such as: hydraulic push rod often breaks down, and the refractory brick of preheater inside often comes off or the like, and particularly coming off of preheater internal refractory brick often taken place.Simultaneously, because fault cause causes that maintenance can influence production again, above various reasons can reduce the operation factor in limestone kiln greatly, increases production cost.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of lime rotary kiln, and purpose is for save energy, saves cost, boosts productivity, and improves pre-heat effect.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of lime rotary kiln, its structure is as follows: kiln hood is connected with the rotary kiln body of inclination, external being provided with of rotary kiln drives the transmission mechanism that the kiln body is rotated counterclockwise, the rear end of rotary kiln body connects the kiln tail, the rotary kiln body is provided with one section reducer near kiln tail place, and material delivering plate is arranged on the inwall of reducer.
Described reducer is a 0.5-3 rice apart from the distance of kiln tail.
Described rotary kiln body is provided with a plurality of resting supports.
Described resting support is 2-8.
The angle of inclination of described rotary kiln body is horizontal by 5-30 degree angle.
Described kiln hood is equipped with sealing-ring.
Described kiln tail is equipped with sealing-ring.
The utlity model has following advantage and effect owing to adopt The above results to make: the utility model is simple in structure, save energy, saves cost, has improved productivity, and pre-heat effect is good.The utility model is to replace the outer preheater of kiln by reducer, and hydraulic efficiency system and hydraulic push rod are the parts of the outer preheater of kiln, and reducer just can play the effect of preheating.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, kiln hood; 2, rotary kiln body; 3, transmission mechanism; 4, material delivering plate; 5, material; 6, reducer; 7, resting support; 8, kiln tail.
Embodiment
Below embodiment of the present utility model 1 is described in detail in conjunction with the accompanying drawings, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1, a kind of lime rotary kiln of the utility model, its structure is as follows: kiln hood 1 is connected with the rotary kiln body 2 that tilts, rotary kiln body 2 outer being provided with drive the transmission mechanism 3 that the kiln body is rotated counterclockwise, the rear end of rotary kiln body 2 connects kiln tail 8, rotary kiln body 2 is provided with one section reducer 6 near kiln tail 8 places, and material delivering plate 4 is arranged on the inwall of reducer 6.Reducer 6 is a 0.5-3 rice apart from the distance of kiln tail.Rotary kiln body 2 is provided with a plurality of resting supports 7.Resting support 7 is 2-8.Resting support 7 is to be used for bearing and turning kiln kiln body 2 and inner kliner coating thereof, material 5, straight section material 8 etc., to guarantee that rotary kiln body 2 can rotate between the inverse time, the quantity of resting support 7 can be decided according to the length of rotary kiln body 2, and this does not do detailed description for routine techniques.The angle of inclination of rotary kiln body 2 is horizontal by 5-30 degree angle.Kiln hood 1 is equipped with sealing-ring, enters to prevent cold wind.Kiln tail 8 is equipped with sealing-ring, enters to prevent cold wind.
The principle of work of the utility model lime rotary kiln is as follows: Wingdale is sent the back here and is entered rotary kiln body 2 from kiln tail 8, and Wingdale is a normal temperature, so that guarantee to calcine the quality of back lime, just Wingdale can be calcined after must being preheating to certain temperature.Because kiln tail 8 is shorter to the distance of reducer 6, when material 5 was sent to reducer 6, the Wingdale temperature failed to reach the required temperature of calcining, must carry out preheating.At reducer 6 places, material 5 is taken up along with the rotation of reducer 6, material 5 is taken to the top of reducer 6 simultaneously by material delivering plate 4, material 5 will constantly be raised, fall repeatedly fully and hot gas flow carries out heat exchange like this, after reaching required preheating temperature, the material 5 that flows out reducer 6 continues to move, continue preheating forward, and when material 5 ran to calcining zone, material temperature has also just reached calcined required temperature.Material 5 is just calcined like this, and the lime after calcining is finished is discharged from kiln hood.
