Description
(1) technical field
The present invention relates to a kind of rotary kiln device, in particular to a kind of air-cooled revolution kiln hood device.
(2) background technique
Currently, most of rotary kiln feed inlet kiln hoods are cooled down using collet water-cooling pattern, there is leakiness during operation
The disadvantages of water, recirculated water perishable to equipment body recycle unsmooth easy boiling, and cooling effect is unobvious, runs whole system
It makes troubles.
(3) summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides the significantly air-cooled revolutions of a kind of efficient stable, cooling effect
Kiln hood device.
The present invention is achieved through the following technical solutions:
A kind of air-cooled revolution kiln hood device, including kiln body and kiln hood cover board, it is characterised in that: close on the kiln hood cover board
Soldering and sealing is connected to the outer housing of arc plate and the two composition closing kiln body end, is welded with internal layer partition in outer housing, internal layer every
Plate and arc board group are at interlayer cavity, and outer housing lower end is welded with the air inlet of connection interlayer cavity, and outer housing top is welded with company
The gas outlet of logical interlayer cavity；Air inlet connects high pressure blower by air supply duct.
The present invention realizes the encirclement to kiln body end by outer housing, and forms interlayer by the setting of internal layer partition
Cavity, and hot stage is in kiln operation process, it needs to enter new material at this time, to make newly to be unlikely to unlikely into material
In into thawing is burnt before kiln, air cooling equipment through the invention carries out cooling isolation, and cold air enters interlayer by air inlet
In cavity, wind speed becomes faster, and constantly takes away the high temperature that kiln body passes to kiln hood, plays protection kiln hood and newly into the work of material
With since air passage rates are fast, heat absorption capacity is strong, cooling effect is obvious.
More excellent technical solution of the invention are as follows:
The air inlet is welded on outer housing lower end and in the taper being inclined outwardly, and taper air inlet makes the wind into interlayer cavity
Speed is accelerated, and the mobility of cold wind is improved.
Its internal feed inlet of connection is provided on the end of the kiln body, the feed pipe for connecting feed inlet is pierced by
The installation of internal layer partition and arc plate, internal layer partition and arc plate has no effect on the original structure and feed operation of kiln hood.
The seam crossing of the internal layer partition and arc plate and feed pipe is filled with sealing cotton and sealant, by seam crossing
Sealing, realize the integral sealing guarantee of interlayer cavity.
The configuration of the present invention is simple, practical, cooling effect is obvious, maintenance easy to install, effectively solves existing water cooling side
Formula is inefficient, leakproofness is poor, easy leak, the shortcomings that easily damaging to apparatus body, is suitable for wide popularization and application.
(4) Detailed description of the invention
The present invention will be further described below with reference to the drawings.
Fig. 1 is schematic view of the front view of the invention；
Fig. 2 is left view structural representation of the invention.
In figure, 1 kiln hood cover board, 2 arc plates, 3 internal layer partitions, 4 interlayer cavitys, 5 air inlets, 6 gas outlets, 7 high pressure blowers, 8
Air supply duct, 9 kiln bodies.
(5) specific embodiment
Attached drawing is a kind of specific embodiment of the invention.The embodiment includes kiln body 9 and kiln hood cover board 1, the kiln hood lid
Sealing welding is connected to the outer housing of arc plate 2 and the two composition closing 9 end of kiln body on plate 1, be welded in outer housing internal layer every
Plate 3, internal layer partition 3 and arc plate 2 form interlayer cavity 4, and outer housing lower end is welded with the air inlet 5 of connection interlayer cavity 4, shell
Body top is welded with the gas outlet 6 of connection interlayer cavity 4；Air inlet 5 connects high pressure blower 7 by air supply duct 8；The air inlet
Mouth 5 is welded on outer housing lower end and in the taper being inclined outwardly；Its inside of connection is provided on the end of the kiln body 9
Feed inlet, the feed pipe for connecting feed inlet are pierced by internal layer partition 3 and arc plate 2；The internal layer partition 3 and arc plate 2 and feed pipe
The seam crossing in road is filled with sealing cotton and sealant.
High temperature is generated in the present invention, in 9 turning course of kiln body and passes to kiln hood, and high pressure blower 7 provides high pressure cold wind
It is rapidly entered in interlayer cavity 4 through air supply duct 8, air inlet 5, since interlayer cavity 4 is narrow wide cone under irregular cycle is in
Shape, air moment high speed can be whirled up flowing after entering, come into contact in a large area inner layer steel plate and sufficiently take away heat, cooling effect is bright
It is aobvious, and damage will not be brought to kiln hood itself.
The present invention is under the continuous air feed of high pressure blower 7, and gas is constantly updated in interlayer cavity 4, and internal-external temperature difference begins
It keeping maximizing eventually, thermal heat transfer capability remains maximum value, and cooling effect is significant, and the air cooling mode is simple and practical in structure,
It not will cause air pollution and the wasting of resources, save operating cost.
Key technology point of the present invention can also consolidate rotating plate and pin shaft by increasing on traditional maintenance door installation form at two,
To realize this function.
