Abstract
The utility model discloses one kind having the anti-alkali corrosion stove roof plate of heat exchange function large scale, it include the cuboid plate body in interlayer structure, it is silicon carbide layer inside plate body, the compound alkali resistant layer of silicon carbide layer outer cladding, the plate body is by growing with the high side formed equipped with several through-holes.The utility model, by changing the structure of kiln top plate, facilitates kiln construction and repair, extends the service life of furnace roof, improve the utilization rate of kiln compared with traditional technology.
Description
Technical field
The utility model belongs to fire resisting material field, and in particular to one kind having the anti-alkali corrosion stove of heat exchange function large scale
Top plate.
Background technology
Lithium battery is the new generation of green high-energy battery of performance brilliance, is now widely used for consumer electronics, new energy
The fields such as automobile and aerospace industry.Positive electrode occupies core status in lithium battery, mainly include cobalt acid lithium, LiMn2O4,
LiFePO4 etc., anode material of lithium battery most domestic is roasted using high temperature kiln, since anode material of lithium battery is used
Raw material can decompose generate penetrating power and the strong lithia of reactivity erodes kiln body in the synthesis process, kiln top is easy
The problems such as peeling, dusting occurs.In order to improve the heat utilization efficiency of kiln, energy consumption is reduced, in the lower region of kiln temperature
It generally requires and exchanges heat, general kiln top uses stainless heat exchanger, seriously corroded shadow of the highly basic to stainless heat exchanger at present
The service life to kiln is rung, research and development corrosion resistance is good, and the stove roof plate with heat exchange function is for extending high temperature kiln
Service life has ten important roles.
Invention content
Goal of the invention：The purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of with heat exchange function
The anti-alkali corrosion stove roof plate of large scale.
Technical solution：In order to reach foregoing invention purpose, what the utility model was specifically performed by：One kind, which has, changes
The anti-alkali corrosion stove roof plate of hot function large scale includes the cuboid plate body in interlayer structure, is silicon carbide layer, institute inside plate body
The compound alkali resistant layer of silicon carbide layer outer cladding is stated, the plate body is equipped with several through-holes by the side grown and height forms.
Wherein, the composite layer that the compound alkali resistant layer is made of zirconium oxide, aluminium oxide, calcium oxide arbitrary proportion.
Further, the center of the through-hole is located on the center line in lateral length direction.
Wherein, the number of the through-hole is 5 ~ 20, preferably 8.
Wherein, the spacing between the adjacent through-holes is equal.
Further, a diameter of 15 ~ 150mm of the through-hole, preferably 70mm.
Further, the length of the plate body is 1000 ~ 2000mm, and width is 300 ~ 800mm, is highly 30 ~ 200mm,
Preferably, length 1800mm, width 620mm are highly 90mm.
The utility model main innovation is at three aspects：The first, the corrosion of anti-highly basic, plate body surface layer are answering for layer
Alkali resistant material is closed, there is good resistance to corrosion in heat-exchange temperature region；The second, plate body internal layer is the carbon for having high heat conductance
Silicon nitride material forms, and has preferable heat transfer effect, and several through-holes is arranged further according to heat transfer requirements, improves ventilation rate；Third, plate
Body is an integral structure, and is convenient for the replacement and construction of kiln top, is improved production efficiency.
Advantageous effect：The utility model, by changing the structure of kiln top plate, facilitates kiln compared with traditional technology
Construction and repair, extend the service life of furnace roof, improve the utilization rate of kiln.
