Using above-mentioned technical proposal, the utility model has the following beneficial effects:
Since the industry firing rotary kiln with kiln structure in kiln includes cylinder of rotary kiln, cylinder of rotary kiln includes heat preservation
Layer, it is provided with the hook abnormity flame retardant coating being made of hook quarl on the inside of insulating layer, is provided in cylinder of rotary kiln
The inner wall of interior kiln round tube of the inner wall equipped with interior kiln hook, cylinder of rotary kiln and interior kiln round tube is hook shape, and hook abnormity is resistance to
Firebrick and interior kiln hook can enable material to take up from the bottom of cylinder of rotary kiln and interior kiln round tube is orderly, along revolution
The direction of rotation of kiln cylinder body is constantly to Gao Yunhang, so that the material in interior kiln and outer kiln can be obtained by sufficient burning in the sky
Or sintering, this process greatly accelerate the rate of drying of material, shorten drying time, avoid material ring formation wall built-up,
To achieve the effect that energy-saving and emission-reduction；If it is the support column wall that ship's head splits unrestrained formula, phase that equalization setting, which has arterial highway both ends, in outer kiln
Heating space is formed between adjacent two support column walls, by taking five support column walls as an example, in the fixation of five support column wall uniform supports
Kiln round tube allows interior kiln round tube to fix and cylinder of rotary kiln is followed to be rotated, and the kiln on adjacent two support columns wall
Hole be it is staggered, be not on the same cross section of cylinder of rotary kiln, the setting of support column wall so that high thermal current return
Helical coil wind-heat stream can be formed in rotary kiln cylinder rotary course, in outer kiln, made heat diffusion distributing equilibrium in outer kiln, can also be made
Interior kiln round tube integrally absorbs heat equilibrium, to make dry materials and burning sufficiently, avoids material ring formation wall built-up, and then shorten revolution
The firing time of kiln reduces the energy consumption of fuel；In this way, just constituting kiln and interior kiln round tube outside five holes inside cylinder of rotary kiln and depositing
Pattern, all materials in inside and outside kiln can obtain constantly stir-frying, it is aerial throw the phenomenon that dissipating, material ring formation is reduced or avoided,
So that material is able to full combustion, meanwhile, in the case where inclination angle is constant, revolving speed is constant, the utility model can achieve height and fill out
Rate is filled, can arrange in pairs or groups simultaneously and handle two different materials, production efficiency is greatly improved, save a large amount of fuel.
Since the end of cylinder of rotary kiln one end is provided with kiln hood, shape between kiln hood and the end of support column wall one end
At outer kiln centralization feed bin, the spacing of outer kiln centralization feed bin can be carried out according to the long inlet amount with outer kiln of section of interior kiln round tube
Adjustment, slightly at horn-like, rotates through rotary kiln moreover, support column wall is that ship's head splits unrestrained formula close to the side of kiln hood side
Material can be easier to enter in outer kiln and be heated in journey, to keep material burning and drying more abundant, improve this reality
With novel Material Filling Ratio, and then the energy consumption of fuel is saved；The other end of cylinder of rotary kiln is provided with kiln head cover and transition
Cover, forms cooling zone, length is depending on outer kiln drop temperature between transition cover and kiln head cover.Cooling zone cylinder inboard wall construction
It is unsuitable blocked up for hook shape high temperature resistant castable, to improve cooling effect, while suitable cooling wind is blasted outside discharge port, contracted
Short cooling time.Smooth internal walls are then changed to closing on kiln head cover discharge outlet, are conducive to concentrate accumulation discharging；Cooling zone inside center
Position is provided with kiln material receiving tube and two burners in one, the length of cooling zone can according to the intensity of cooling of outer kiln discharge port into
Row adjustment, support column wall are that ship's head splits unrestrained formula close to the side of kiln hood side, slightly at horn-like, are conducive to the flame of burner
Spray feed enters in heating space, and interior kiln round tube is accessed in transition cover by interior kiln material receiving tube, discharges with kiln outside transition cover lower part is located at
The outer kiln discharging synchronization of mouth is cooled down in cooling zone, kiln head cover is then exhausted from, since one end of interior kiln material receiving tube is in transition cover
Interior, the other end passes through kiln head cover, is arranged with a transmission gear ring on interior kiln discharge port, and interior kiln material receiving tube rotation can be driven cooling simultaneously
Discharging is completed, so that cooling is more abundant.
Since interior kiln round tube is segmented manufacture, one end of the interior each segment of kiln round tube is horn-like interface, interior kiln circle
The outer surface of each interface of pipe is coated with silicon carbide castable or high temperature resistant clay, and the surface of interior kiln circular tube external wall is equipped with
Anti-skidding muscle slot, high temperature cotton are filled gap, can be guaranteed the leakproofness of interior kiln round tube using silicon carbide castable or high temperature resistant clay,
Equipped with anti-skidding muscle slot to ensure not generating displacement between pipe wall in rotary kiln rotation, cylinder of rotary kiln inner wall is built according to industrial rotary kiln
Build regulation construction.
Since one end of interior kiln round tube is accessed in the interior kiln material receiving tube, insertion depth is to ensure not material leakage, two pipes
Between transposition section should reserve gap appropriate as air duct, transition cover is equipped with a ventilation window close to the side of cooling zone, outside kiln
The room temperature cooling wind for blasting cooling material, enters in transition cover after heat absorption through window, then enters interior kiln wife through reserved air duct
Combustion.Since the heat source of interior kiln comes from outer kiln, temperature is close with outer kiln, therefore does not need the individually inwardly interior conveying combustion of kiln again
Material, as long as and input combustion air (kiln hood combustion fan is in charge of feedings, synchronous also cooling in kiln discharging), while will drying rotary kiln
Or outer kiln burning conveys the thermal cracking flue gas for needing high temperature to flash back of coming not to the utmost, is sent into together in interior kiln by transition cover.
Cooling zone is passed through due to one end of burner and extendes back out kiln head cover for fuel conveying, the other end of burner is set
It is placed in the burner holding chamber, there are safe spacings appropriate for the front end of burner and interior kiln support column wall, guarantee burning
Device will not collide with support column wall and damage, and also ensure that the flame in burner uniformly can enter heating sky by spray feed
Between.
Since interior kiln round tube, interior kiln hook and support column wall can be by silicon carbide, corundum class nonmetallic materials or high temperature resistants
Material is made, and is not limited to carbofrax material, under the conditions of meeting temperature, can also use other metals or non-metallic material
Material manufacture, reduces the requirement and cost to manufacture material.
