9 be bent to form it is snakelike.
In the inventive solutions：
1) fire grate uses particular design, and fire grate movement conveying realizes the collection of high-temperature material 7, transports integrated treatment, needs
Emphasis is wanted to solve three key issues：
1 heat-transfer surface 5 has larger collection area, it is sufficient to which receiving space trickles down the area of material；
2 heat-transfer surfaces 5 are resistant to the high temperature of material；
Stress is separated with heated element in the structure of 3 heat-transfer surface 5, i.e., stress not by high-temperature heating (be not directly contacted with height
Warm material), it is heated not by too high active force.
2) heat-transfer surface within the specific limits can by width, Design of length it is larger, width is up to 20 meters, and length is up to 50
Collect rice, the whereabouts after entirely appropriate high-temperature particle is shed.
3) in order to solve heat-transfer surface tolerance material high temperature (more than 900 DEG C), using solution below：
1 high temperature resistant heat insulation layer is made using the lightweight alumina silicate castable refractory for being resistant to 900 DEG C, castable refractory tool
There is certain thermal insulation, it is to avoid the heated overtemperature of the frame of resistance to heat channel of carrying lightweight alumina silicate castable refractory.
3) stress is separated with heated element in the grate-type of resistance to material movement conveying surface (heat-transfer surface) structure：Drive chain exists
Under, the upper surface of fire grate upper, the upper surface of fire grate separates high-temperature material with drive chain.Drive chain is not by high-temperature material
Directly heat, but drive chain drives fire grate and its material movement above under motor and reductor effect, therefore is
Force-summing element, fire grate is fixed between drive chain and moved, and it receives the heating of high-temperature material but stress very little.
4) cooling water pipe with row is provided below in drive chain, reduces drive chain temperature to return simultaneously by radiation heat transfer
Receiving drive chain low temperature exhaust heat is used for heating.
The present invention the course of work be：
Obtain slag drop after blast furnace cinder air quenching to be sprayed into housing 4 by melting powder entrance 3, slag drop coagulates in the air
Gu after form high-temperature material 7, air quenching waste gas discharges housings 4 by high-temp waste gas outlet 8, and high-temperature material 7 is transported on heat-transfer surface 5
Discharging opening.
The frame of resistance to heat channel 17 is penetrated in the hole on closed chain by the axle 18 at its two ends, then closed chain is hidden in the frame of resistance to heat channel
Below 17.High temperature resistant heat insulation layer 11 is embedded in the groove for the frame of resistance to heat channel, reduces the temperature of the frame of resistance to heat channel 17, improves resistance to heat channel
The intensity of frame 17, and reduce the radiation loss for collecting transport device lower surface.Due to the frame of resistance to heat channel 17 by high-temperature material 7 with closing
Chain is separated, and closed chain stress is not heated directly, so as to ensure that the intensity of closed chain, and the frame of resistance to heat channel 17 then only by
Heat does not stress.Heat-transfer surface 5 is when travelling forward into housing 4, and water cooling tube 9 is arranged in closed chain bottom, passes through radiation heat transfer
Closed chain temperature is reduced, and absorbed closed chain waste heat is used for plant area's heating.Fire grate directive slide track 6 is that chain row is oriented to cunning
Rail, mainly supports lower chain row, it is to avoid be broken because chain row's deadweight is overweight.
Exemplary description is done to the present invention above, it should explanation, in the situation for the core for not departing from the present invention
Under, any simple deformation, modification or other skilled in the art can not spend the equivalent substitution of creative work equal
Fall into protection scope of the present invention.
