Description
Technical field
The present invention relates to stoves, and in particular to a kind of sintering furnace.
Background technique
Sintering furnace is widely used in the preparation and research of the new materials such as nanocatalyst, glass, ceramics, steel, cement.
During the sintering process, heating rod is set with lower section typically above product, heating workpiece will cause workpiece heating not in this way
Uniformly as a result, influencing sintering effect.However, for needing isolating oxygen in some poor thermal conductivities, large bulk density and sintering process
The material of gas, calcination time needed for traditional sintering furnace is too long, product heating is uneven, influences sintering effect.
Summary of the invention
It is an object of the invention to: a kind of sintering furnace is provided, sintering effect is ideal, and it is simple to operate, it efficiently solves
The problems such as sintering furnace calcination time length, uneven heating.
The technical solution of the invention is as follows: the sintering furnace includes furnace body, furnace lining is equipped in furnace body inner surface, in furnace lining
On resistance wire is installed, it is characterized in that: installing furnace inner cylinder in furnace body, furnace inner cylinder is trapped among centre by resistance wire；The furnace inner cylinder
It is made of communicating pipe, inside drum cover, thermometric sleeve, gas vent, inner sleeve, inner cylinder and heat generating member, inner sleeve is installed in inner cylinder,
Heat generating member is installed at the center of inner sleeve, is connected between inner cylinder and inner sleeve several communicating pipes, inner cylinder is arranged at inner cylinder top
It covers, is welded with thermometric sleeve and gas vent on inside drum cover.
Wherein, the heat generating member includes electrothermal tube, fixed frame and support column, and the electrothermal tube of more infrared rays is mounted on solid
Determine on frame, fixed frame and electrothermal tube are fixed on furnace body by support column.
Wherein, protective net is installed on fixed frame.
Wherein, the material of the furnace lining is alumina silicate.
Compared with traditional sintering furnace, sintering furnace of the invention is had the advantage that
1) sintering furnace is by heating simultaneously inside and outside resistance wire on the electrothermal tube and furnace lining in the middle part of inner cylinder, using inside and outside cylinder simultaneously
There are more root canal connection furnace cores in the mode of heating, the inside of heating cylinder, and heat can make cylinder and produce well into inner barrel
The heat exchange of product is more abundant, and temperature is uniform, and within 18 DEG C of burner hearth upper and lower temperature difference, calcination time is reduced compared with conventional sintering furnace
1/3 or more.
2) burner hearth uses high temperature resistant alumina silicate fibre module, and heating, cooling speed is fast, energy conservation and environmental protection.
3) furnace core heating use infrared ray black body radiation electrothermal tube, radiance stablize, no harmful radiation, non-environmental-pollution,
High temperature resistant, thermal inertia are small, thermal response speed is fast, thermal conversion efficiency is high.
4) after using the above structure, workpiece is put into sintering furnace, by the way of being heated inside and outside the cylinder simultaneously, and heat can
Enter inner barrel by communicating pipe, keep the heat exchange of cylinder and product more abundant, be uniformly heated, promotes sintering effect,
Sintering effect of the present invention is good, simple to operate.
