To the outside of exhaust pipe 18, the outside of the second shaft 27 is angularly equipped with multiple flabellums 272, and one end of the second shaft 27 is fixedly connected with
Terminal pad 271, one end of first rotating shaft 6 are fixedly connected with gear 273, and gear 273 is rotated by planetary gear 274 and terminal pad 271
Connection.First rotating shaft 6 rotates, and band moving gear 273 rotates, and gear 273 is by driving the rotation of planetary gear 274 to drive terminal pad
271 rotations to drive the rotation of the second shaft 27, and then drive flabellum 272 to be rotated, and the revolving speed of flabellum 272 and row
Tracheae 18 is asynchronous with the revolving speed of first rotating shaft 6 so that flabellum 272 rotation near generate negative pressure, be conducive to exhaust gas from
Exhaust pipe 18 imports the inside of the second cavity 22, accelerates rate derived from exhaust gas, to reduce heat of the exhaust gas in export process
Amount loss.
Concrete operations process is as follows:
When work, rubbish is imported to the inside of incinerator 1 by feed inlet 33, close feed inlet 33, heat coil 3 is sent out
Heat burns rubbish, and controller control drive module driving incinerator 1 is rotated, and drives rubbish to be rotated, simultaneously
Under the action of helical blade 2, rubbish is stirred, is conducive to rubbish and sufficiently burns, exhaust gas by the first air inlet 19 into
Enter exhaust pipe 18, the exhaust gas into exhaust pipe 18 passes through the second air inlet 8 into the inside of the first cavity 7, and exhaust gas is to elastic plate
11 apply pressure, so that elastic plate 11 deforms and squeezes fixture block 12 to the movement of the direction of card slot 13, until fixture block 12 is sticked in card
The inside of slot 13, spring 10 is stretched in the process, so that first rotating shaft 6 is fixed with 18 phase of exhaust pipe, when smog sense
After answering device to sense flue gas, signal is passed to controller by smoke inductor, and controller controls motor 5 and works, at this time motor 5
First rotating shaft 6 is driven to rotate, the rotation of first rotating shaft 6 drives exhaust pipe 18 to rotate, so that the rotation of the first auger 20 is driven, to burning
The rubbish of center position is stirred in furnace 1, when drive module control incinerator 1 rotates, helical blade 2 and the first auger
20 rotate simultaneously, can stir simultaneously to the rubbish of 1 inward flange of incinerator and center position, when drive module controls incinerator 1
When not rotating, helical blade 2 is not rotated, and the rotation of the first auger 20 can stir the rubbish of center position in incinerator 1
It mixes, so as to select the position of stirring according to the actual situation, is conducive to the burning of rubbish, while being generated in Refuse Incineration Process useless
Gas, exhaust gas enters the inside of exhaust pipe 18 by the first air inlet 19, and enters gas-guide tube 24 by gas outlet 21, finally enters
Waste heat boiler 25 is brought extra power into play into the exhaust gas in waste heat boiler 25, is converted heat under the action of Turbo-generator Set
Electric energy realizes power generation, and after waste incineration, exhaust gas passes through gas-guide tube 24 completely and leads into after 25 inside of waste heat boiler, opens
Slag notch 28 exports the rubbish inside incinerator 1, the inside of compression box 30 is imported by residue outlet 29, while when exhaust gas is complete
After full discharge, elastic plate 11 is no longer pressurized, and under the elastic force effect of spring 10, elastic plate 11 is pulled to restore to reset condition, from
And fixture block 12 is driven to be detached from card slot 13, due to being set as screw pair connection, first rotating shaft between exhaust pipe 18 and first rotating shaft 6
6 rotations, under the axial restriction effect of pressing plate 31, so that exhaust pipe 18 moves right, band dynamic pressure plate 31 moves right, to compression
Rubbish inside case 30 is squeezed, and is realized pressure slag, is reduced the space that occupies of rubbish waste residue, facilitate the later period to rubbish at
Reason.
Although the present invention be illustrated by specific embodiment, it will be appreciated by those skilled in the art that, do not departing from
In the case where the scope of the invention, various transformation and equivalent substitute can also be carried out to the present invention.In addition, being directed to particular condition or material
Material, can do various modifications to the present invention, without departing from the scope of the present invention.Therefore, the present invention is not limited to disclosed tool
Body embodiment, and should include the whole embodiments fallen within the scope of the appended claims.
