Description
Technical field
The present invention relates to stove, and in particular to a kind of sintering furnace.
Background technology
Sintering furnace is widely used in the preparation and research of the new materials such as nanocatalyst, glass, ceramics, steel, cement.
In sintering process, heating rod typically all is set with lower section above product, such heated partses can cause workpiece heat not
Uniform result, influences sintering effect.However, greatly and needing isolating oxygen in sintering process for some poor thermal conductivities, bulk density
The material of gas, calcination time needed for traditional sintering furnace is long, product heating is uneven, influences sintering effect.
The content of the invention
It is an object of the invention to:A kind of sintering furnace is provided, sintering effect is preferable, simple to operate, efficiently solves
The problems such as sintering furnace calcination time length, heated inequality.
The present invention technical solution be：The sintering furnace includes body of heater, furnace lining is provided with body of heater inner surface, in furnace lining
On resistance wire is installed, it is characterized in that：Stove inner cylinder is installed, stove inner cylinder is trapped among centre by resistance wire in body of heater；Described stove inner cylinder
It is made up of communicating pipe, inside drum cover, thermometric sleeve, steam vent, inner sleeve, inner barrel and heat generating member, inner sleeve is installed in inner barrel,
Heat generating member is installed at the center of inner sleeve, is connected between inner barrel and inner sleeve several communicating pipes, inner cylinder is arranged at inner barrel top
Thermometric sleeve and steam vent are welded with lid, inside drum cover.
Wherein, described heat generating member includes electrothermal tube, fixed mount and support column, and many ultrared electrothermal tubes are arranged on solid
Determine on frame, fixed mount and electrothermal tube are fixed on body of heater by support column.
Wherein, protection network is installed on fixed mount.
Wherein, the material of the furnace lining is alumina silicate.
Compared with traditional sintering furnace, sintering furnace of the invention has advantages below：
1）Sintering furnace is heated simultaneously on the electrothermal tube and furnace lining in the middle part of inner cylinder inside and outside resistance wire, using heating simultaneously inside and outside cylinder
Mode, there are a many pipes connection combustion chambers inside of heating cylinder, and heat can make cylinder and product well into inner barrel
Heat exchange is more abundant, and temperature is uniform, and within 18 DEG C of burner hearth upper and lower temperature difference, calcination time reduces 1/3 compared with conventional sintering stove
More than.
2）Burner hearth uses high temperature resistant alumina silicate fibre module, and heating, cooling speed is fast, energy-conserving and environment-protective.
3）Combustion chamber heating uses infrared ray black body radiation electrothermal tube, and radiance is stable, no harmful radiation, non-environmental-pollution,
High temperature resistant, thermal inertia are small, thermal response speed is fast, thermal conversion efficiency is high.
4）Using said structure, workpiece is put into after sintering furnace, and by the way of heating simultaneously inside and outside cylinder, and heat can
Inner barrel is entered by communicating pipe, makes the heat exchange of cylinder and product more abundant, is uniformly heated, sintering effect is lifted,
Sintering effect of the present invention is good, simple to operate.
