Wherein, the rotating cylinder left end preferably is provided with the grooved support roller, and the rotating cylinder right-hand member preferably is provided with the flat pattern support roller, and two support rollers support the rolling ring corresponding with it respectively.Under the effect of expanding with heat and contract with cold, feed end is spacing by the grooved support roller, guarantees the correct engagement of big pinion, and rotating cylinder can only expand to discharge end, and the flat pattern support roller can absorb the expansion and the contraction of rotating cylinder.
Can be provided with screw(-type) feeder between inner core and the feed hopper, can better material be advanced in the inner core.
Discharging seal box top preferably is provided with exhaust emission tube, can the waste gas that heating produces be discharged.
Heater can be resistance wire heating, fuel burner nozzle heating or coal heating, when using fuel burner nozzle heating or coal heating to lead at the body of heater top fume extractor is set.
The operation principle of the utility model is following:
(1) screw(-type) feeder of feed end layout falls into inner core with the mass transport in the loading hopper.
(2) fall into the material of inner core, under the promotion of spiral pusher groove, according to fixing pitch, to port of export pusher, in the process of pusher, material rotating plate guarantees the material thermally equivalent with material turning.
(3) material movement in the inner core falls into tube to the port of export, and the spiral pusher groove in the quilt in the tube promotes to advance to the port of export.
(4) material movement in the tube falls into urceolus to the port of export of middle tube, is promoted by the spiral pusher groove in the urceolus, to port of export motion, until the feed opening that falls into the discharging seal box, accomplishes motion process.
(5) in above motion process; The heat that heater (can be resistance wire heating, fuel burner nozzle heating or coal heating) produces passes through outer tube wall; With the material in the heat transferred urceolus; Middle tube and inner core are under the conduction of urceolus internal heat, and the material of barrel in tube that passes through respectively separately conducts heat.
The utility model applicable scope is: (1) temperature: the material baking heat below 1000 ℃; (2) material: powder or particulate material.
The beneficial effect that the utility model had is: to heat relatively having of rotary furnace outward following different with single channel:
(1) energy consumption difference: the heating furnace that single channel heats rotary furnace outward is twice than the furnace volume of the outer heating rotary furnace of triple channel; Heating power (no matter being electrical heating or combustion gas heating) also is the multiple relation; Same specific yield is saved 50% energy consumption than the outer heating rotary furnace of single channel.
(2) warm area difference: single channel heats rotary furnace outward, and the temperature subregion is fuzzy, needing to be unfavorable for the roasting of thermograde; Triple channel heat outward rotary furnace from inner core to the tube at last to urceolus, temperature is progressively to improve, the stove subregion is obvious, helps temperature by the roasting of technology gradient.
