Technical field
The utility model relates to a kind of tubular type high temperature rotating stove, more particularly, relates to a kind of high-temperature calcination stove of the boiler tube structure of having improved.Be mainly used in the technical process such as drying, high-temperature calcination, High Temperature Gas solid phase reaction, high temperature refining, purification of powder material.
Background technology
Powder materials such as glass sand, carbide alloy, various pottery, soft magnetic ferrite, battery and energy and material, inorganic pigment, inorganic filler generally all will be through technical process such as super-dry, high-temperature calcination, refining, purifications in the middle of manufacturing process.Because simple in structure, easy to make, maintenance cost is low, can work continuously, rotary furnace is applied extensively at many industrial circles.At present, all be through type generally to the high-temperature heat treatment rotary furnace of powder material, in the operating process, superfine material is along with the rotation of spherical hearth is slided toward low side gradually from high-end, can not well be scatter, material is heated inhomogeneous, dry and calcining weak effect; Participating in reaction as gas is, gas-solid contact insufficient; When several materials mix, can not mix.Cause thermal effectiveness undesirable thus, constant product quality is poor, and performance indications are low.
US4052149 and US4101630 disclose a kind of rotary furnace, are made up of two coaxial circles tubular boiler tubes, and interior pipe leads to hot-air and heats, and can increase the heat transfer uniformity, accelerates heat treatment efficiency.
US5997289 discloses a kind of finned rotary furnace, and fin is inverted v-shaped, is in staggered distribution at inboard wall of burner hearth, is conducive to material and is evenly mixed in boiler tube.
US4288217 then discloses a kind of spirality charging rotary furnace, and a whole circle and the 3/4 circle spirality fin of the band tapering of some level altitudes is installed in burner hearth, the refluence of material when preventing from feeding in raw material.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of rotary furnace that can improve the thermal effectiveness of powder material under the equal volume equal temperature is provided.
The technical scheme of technical solution problem is that tubular type high-temperature calcination reaction rotary furnace comprises the hollow cylindrical burner hearth that is driven by drive unit, the groups of group spoke more than inboard wall of burner hearth is provided with, have between the spoke group at interval, establish dividing plate in the burner hearth, be provided with the hole in the middle of the dividing plate, dividing plate is divided into I chamber and II chamber to burner hearth; The spoke group is made up of at least three spokes, and spoke is circumferential and is evenly distributed on the inboard wall of burner hearth, and is gapped between the spoke.
All right, powder material high-temperature calcination reaction tubular type rotary furnace also comprises the travel(l)ing rest that supports described hearth outer wall.
All right, spoked shape is sheet or column or tubulose.
All right, travel(l)ing rest can be adjusted burner hearth and be 0 degree to 30 degree inclinations.
All right, the spoke group is made up of six roots of sensation spoke.
All right, burner hearth rotates under the driving of drive unit, and the rotating speed of burner hearth can be regulated.
Advantage of the present utility model is, use above structure, drive unit drives the burner hearth rotation, after powder material enters the I chamber of burner hearth, slowly rotation along with burner hearth, progressively move to the II chamber, and kick up and scatter at the spoke that the process that moves to the II chamber constantly is distributed on spoke group on the inboard wall of burner hearth, thereby disperseed fully; When gas fed, the powder material that is fully disperseed fully contacted with atmosphere; When several powder materials need mix, spoke played stirring action, made mixing of materials even; Have between the spoke group at interval, make the powder thing polymerization in the interval again of being loose by last one group of spoke component, the powder material that regroups is disperseed again in next group spoke group, through dispersion, polymerization, dispersion repeatedly, make when the powder thing disperse more even; Begin to flow to the II chamber during point at the bottom of powder material moves to the dividing plate place and reaches the edge in hole, can guarantee that like this powder material stays for some time in advance in the I chamber, guarantee the effect of heating.
Powder material high-temperature calcination reaction tubular type rotary furnace also comprises the travel(l)ing rest that supports described hearth outer wall, travel(l)ing rest can be adjusted burner hearth and be 0 degree to 30 degree inclinations, burner hearth has certain inclination, adds the control to the burner hearth rotary speed, can control the speed of the powder material that enters burner hearth.
