Including turning round boiler tube, shell, gas-guide tube, rotary joint；Wherein, revolution boiler tube includes inner layer sleeve and outer layer sleeve, internal layer set
Pipe is nested together with passing through stainless steel leaf spring between outer layer sleeve and contact fixing, detachably；In shell include burner hearth,
Control cabinet, motor control burner hearth and motor by control cabinet；Inner layer sleeve is fully located in burner hearth, outer layer sleeve both ends part
Outside burner hearth；Shell two sides are provided with rotation support and are connected with outer layer sleeve；By leading between inner layer sleeve and rotary joint
Tracheae connection.
Be connected and sealed between the outer layer sleeve both ends and gas-guide tube by thimble connector, to fixed gas-guide tube with
Boiler tube；On the outside of inner layer sleeve both ends, support construction is additionally provided between outer layer sleeve and gas-guide tube, which can be bracket
Deng to further fix the connection of boiler tube and gas-guide tube.
Inner layer sleeve both ends are internally provided with chamfering end socket, and specifically making inner layer sleeve import and export is in certain gradient,
The chamfering end socket makes inner layer sleeve both ends not have dead angle, and the material after can making reaction is easy to pour out from inner layer sleeve；Air guide
Between pipe and inner layer sleeve plus Graphite pad is sealed.
Outer layer sleeve is stainless steel material, and heat-transfer effect is good, and can bear biggish stress at high temperature；Inner layer sleeve and
Gas-guide tube is high temperature resistant non-metallic material, is chosen in particular from quartz, corundum, ceramics, silicon carbide, graphite, when rotary furnace works, instead
It should be carried out in inner layer sleeve, avoid material to material deterioration caused by the corrosion of metal boiler tube and high-temperature metal boiler tube.
Heating device is provided in burner hearth, control cabinet can control burner hearth and motor is heated and rotated, which can
To realize that details are not described herein using this field routine techniques.
Caused by the deformation effect of stainless steel leaf spring can reduce inner layer sleeve and outer layer sleeve because of coefficient of expansion difference
Nonmetallic inner layer sleeve is squeezed the risk of rupture under high temperature.
The rotation support can be in the structures such as bearing, such as Yixing Shang Nenglu industry Co., Ltd RZ series rotary furnace
Rotation support, which can play further supporting role to boiler tube.
When working condition, material is placed in nonmetallic inner layer sleeve, and Gaseous materials are connect by air inlet through inlet end rotation
Head and nonmetallic gas-guide tube enter the inner layer sleeve in high-temperature region, then enter outlet side rotation through nonmetallic gas-guide tube again and connect
Head, then revolution boiler tube is flowed out by gas outlet.Whole process can automatically control the heating and rotation of rotary furnace by control cabinet.
In conclusion material does not contact high-temperature metal material in the entire rotary furnace course of work, material is avoided to metal
Material deterioration caused by the corrosion of boiler tube and high-temperature metal boiler tube, while reducing the risk of nonmetallic boiler tube rupture, Ke Yishi
The high-temperature calcination or reaction of material in existing particular atmosphere.
