Description
Technical field
The utility model relates to a kind of small-sized rotary kilns.
Background technique
The explosive growth of new energy battery material drives the demand in power battery material powder market to continue vigorous, phase
The demand also sustainable growth for closing equipment, in this development process, to product quality, the equipment of production efficiency of equipment, equipment production
The requirements such as energy consumption can propose more and more to require.Liner material is single in the relevant device that battery material is smelted in the market,
Use occasion limitation is big, such as the use of metal liner, has corrosiveness to metal using rear powder (magnetisable material), to environment
Pollution also has an impact.The conductive performance of metal liner is also not optimal, can give a discount production efficiency in this way.At present I
The small-sized rotary kiln of company's research and development uses material replaceability inner-tube structure, and liner is more flexible using selecting, and range is bigger, production
More efficient, performance is more perfect.
Summary of the invention
The utility model aim is to provide a kind of small-sized rotary kiln in view of the defects existing in the prior art.
The utility model to achieve the above object, adopts the following technical scheme that a kind of small-sized rotary kiln, including rotary kiln bottom
Seat, the upper end of the rotary kiln pedestal is connected with left end cap insulation portion, the upper end of the rotary kiln pedestal by first connecting rod
Right end cap insulation portion is connected with by the second connecting rod；It is provided between the left end cap insulation portion and right end cap insulation portion built-in
The heater of heating wire is provided with liner portion in the heater；It is arranged outside the left end cap insulation portion and right end cap insulation portion
There is cap；The liner portion is made using graphite material or carbofrax material.
The utility model has the beneficial effects that the utility model clever structure, material are innovated, original stent is broken
Formula, so that the replacement of small-sized rotary kiln core liner is more convenient, liner material can also be used multiple material and realize diversification material
Processing, market plane tropism has more advantage, and liner has extremely strong corrosion resistance, for the volatilization etchant gas in sintering process
With very strong patience, the service life of equipment can be greatly prolonged.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Shown in Fig. 1, it is related to a kind of small-sized rotary kiln, including rotary kiln pedestal 6, the upper end of the rotary kiln pedestal 6 passes through
First connecting rod is connected with left end cap insulation portion 3, and the upper end of the rotary kiln pedestal 6 is connected with right end cap by the second connecting rod
Insulation portion 5；The heater 2 of in-built electrical heated filament, the hair are provided between the left end cap insulation portion 3 and right end cap insulation portion 5
Liner portion 4 is provided in hot body 2；Cap 1 is provided with outside the left end cap insulation portion 3 and right end cap insulation portion 5；The liner 4
Portion is made using graphite material or carbofrax material.
In material layer by the production with different materials, different materials is applicable in the small-sized rotary kiln liner of the utility model
In different working conditions, and liner material provides the effect of perfect heat transmitting, required for maximizing during transfer reaction
Energy；And robustness intensity is very considerable, reduces loss of the external factor for liner, and ensured entire liner uses the longevity
Life.
The small-sized rotary kiln liner material of this research and development has been done corresponding for the metal liner problem in the market
It improves and invents.The first material uses high temperature resistant, the small high-quality graphite material production of the good thermal expansion coefficient of thermal conductivity.Graphite tool
There is good chemical stability, by the graphite of special processing, there is the features such as corrosion-resistant, thermal conductivity is good, and permeability is low, it can be big
Amount is satisfied with industrial demand.Second liner material uses carbofrax material, high rigidity that silicon carbide ceramics has, height
The features such as corrosion resistance and higher elevated temperature strength, the chemical corrosion resistance of silicon carbide is good, intensity is high, hardness is high, wearability
Energy is good, coefficient of friction is small, and high temperature resistant, thus is the ideal material for manufacturing liner.It is combined with graphite material with clock synchronization, is rubbed
It wipes coefficient ratio aluminium oxide ceramics and hard alloy is small, thus can be used for high PV value, especially make in the operating condition of conveying strong acid, highly basic
With.It is used suitable for high performance sealing, the operating condition of especially high PV value and resistance to strong acid, highly basic, service life and work
Reliability improve.Multifarious several materials, such as aluminium oxide, composite ceramics etc., for liner material can also be provided in my company
The selection of material replaceability can be accomplished to facilitate and fast.
The present invention tests production and processing field towards entire lithium battery powder, which replaces rotary kiln,
Be characterized in that the Simple removable formula liner researched and developed using my company, make its process in for parts replacement convenience and
Liner diversity has diversity for meeting the liner under different working conditions, and liner material also includes to prolong the service life
Design concept.Structure of the invention is ingenious, and material innovation is realized using versatile, and working efficiency greatly improves, later period consumption
Cost significantly drops, and the feature of environmental protection also greatly improves, applied widely.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
