Abstract
The utility model discloses a kind of rotary kiln, including rotary kiln body and the kiln head box for being located at turn around at kiln body kiln hood rising sealing process, main burner has been fastened on kiln head box, the combustion head of main burner is located at turn around in kiln body, concurrent heating burner has also been fastened on the lateral wall of kiln head box, concurrent heating burner is not higher by kiln head box lateral wall inner surface, the rotary kiln, the concurrent heating burner for not being higher by its inner surface is installed on the lateral wall of kiln head box, to ensure that the molten iron being calcined in rotary kiln body is dropped out by kiln hood, while not damaging concurrent heating burner, realize to the heating at rotary kiln body kiln hood, its simple structure, effectively prevent because temperature is too low at rotary kiln body kiln hood, and cause molten iron ring formation, the phenomenon that yield is reduced.
Description
Technical field
The utility model is related to Thermal Equipment technical field, particularly relates to a kind of rotary kiln.
Background technology
The nucleus equipment that rotary kiln is produced as ferronickel, is a revolving body being obliquely installed for high-temperature heating, revolution
Body high order end is kiln tail, and low order end is kiln hood, and the kiln head box of sealing process has been provided with kiln hood, is fixed with by kiln hood on kiln head box
To the main burner stretched into rotary kiln, during work, material is entered by rotary kiln, from kiln after reduction roasting in rotary kiln
Head exit drops out, and carries out next technique.Ferronickel production technology is upgraded to back by traditional rotary kiln-mineral hot furnace-converter smelting process
After rotary kiln direct-reduction process, technological requirement is answered, ignition temperature is greatly improved in rotary kiln, then, kiln hood is near kiln head box part
Dorsad main burner flame direction, temperature is all compared to relatively low, it is impossible to ensure the temperature that production needs, and easily causes roasting in rotary kiln
Molten iron ring formation, yield reduction, and utilization rate of equipment and installations, the waste of labour.
The content of the invention
The purpose of this utility model is to provide a kind of rotary kiln.
Realizing the technical scheme of the utility model purpose is, a kind of rotary kiln, including rotary kiln body and is located at turn around
The kiln head box of sealing process is played at kiln body kiln hood, main burner has been fastened on kiln head box, the combustion head of main burner is located at back
In rotary kiln body, concurrent heating burner is also fastened on the lateral wall of kiln head box, concurrent heating burner is not higher by kiln head box lateral wall inner surface.
Further, concurrent heating burner is located at kiln head box just on the lateral wall of kiln hood.In this way, the flame of concurrent heating burner spray combustion
It is just even sprayable to kiln hood in reduction roasting in rotary kiln body, is sufficiently used for, fire heat utilization efficiency high.
Further, concurrent heating burner medial end surface flushes with kiln head box lateral wall inner surface.To ensure rotary kiln sheet
The molten iron of roasting is dropped out by kiln hood in vivo, and while will not causing to damage to concurrent heating burner, concurrent heating burner can be closer to rotary kiln
Body kiln hood, improves combustion heat utilization efficiency.
The utility model rotary kiln, installs the concurrent heating burner for not being higher by its inner surface, with true on the lateral wall of kiln head box
The molten iron for protecting roasting in rotary kiln body is dropped out by kiln hood, while concurrent heating burner is not damaged, is realized to rotary kiln body kiln hood
The heating at place, its simple structure effectively prevent because temperature is too low at rotary kiln body kiln hood, and cause molten iron ring formation, yield
The phenomenon of reduction.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model rotary kiln.
Specific embodiment
As shown in figure 1, a kind of rotary kiln, including rotary kiln body 1 and it is located at turn around playing closing at kiln body kiln hood 11
The kiln head box 2 of effect, has fastened main burner 3 on kiln head box 2, the fire end 31 of main burner 3 is located at turn around in kiln body 1,
Concurrent heating burner 4 is also fastened on the lateral wall of kiln head box 2, concurrent heating burner 4 is not higher by the lateral wall inner surface of kiln head box 2.Concurrent heating is burnt
Mouth 4 is located at kiln head box 2 just on the lateral wall of kiln hood 11.The medial end surface of concurrent heating burner 4 and the lateral wall inner surface of kiln head box 2
Flush.
The utility model rotary kiln, concurrent heating burner 4 is used to being heated at rotary kiln body kiln hood 11；Concurrent heating burner 4
Inside end is not higher by the lateral wall inner surface of kiln head box 2, to prevent the molten iron dropped out by kiln hood 11 in rotary kiln body 1 from smashing,
And greatly shortening the service life of concurrent heating burner 4, i.e., the structure can use with ensuring concurrent heating burner 4.
The utility model rotary kiln, installs the concurrent heating burner 4 for not being higher by its inner surface on the lateral wall of kiln head box 2, with
Ensure that the molten iron of roasting in rotary kiln body 1 is dropped out by kiln hood 11, while concurrent heating burner 4 is not damaged, realize to rotary kiln sheet
Heating at body kiln hood 11, its simple structure effectively prevent because temperature is too low at rotary kiln body kiln hood 11, and cause molten iron
Ring formation, the phenomenon that yield is reduced.
The utility model rotary kiln, for the flame for making concurrent heating burner 4 spray combustion is sufficiently used for reduction roasting, improves combustion heat utilization
Rate, it is preferred that concurrent heating burner 4 is located at kiln head box 2 just on the lateral wall of kiln hood 11；To ensure roasting in rotary kiln body 1
Molten iron is dropped out by kiln hood 11, and while will not causing to damage to concurrent heating burner 4, concurrent heating burner 4 can be closer to rotary kiln body kiln
First 11, combustion heat utilization efficiency is improved, it is preferred that the medial end surface of concurrent heating burner 4 flushes with the lateral wall inner surface of kiln head box 2.
The utility model rotary kiln, the air hose of connection, Gas Pipe are essential needed for the burning that concurrent heating burner 4 is completed,
But category prior art, the utility model is no longer illustrated.
