In the technical scheme of the invention, the following steps are provided:
1) The fire grate adopts special design, and the fire grate removes the material of transporting, realizes the collection of high temperature material and transports integration processing, needs to focus to solve three key problems:
1 the heat exchange surface 8 has a larger collection area, which is enough to accept the area of the space scattered materials;
2 the heat exchange surface 8 can resist the high temperature of the materials;
the heat exchange surface 8 structurally separates the stress and the heated element, namely the stress is not heated by high temperature (is not directly contacted with high temperature materials), and the heated element is not subjected to excessive high acting force.
2) The heat exchange surface can be designed to be larger in width and length within a certain range, the width can reach 20 meters, the length can reach 50 meters, and the heat exchange surface is completely suitable for falling collection after high-temperature particles are thrown.
3) In order to solve the problem that the heat exchange surface tolerates the high temperature of materials (more than 900 ℃), the following solution is adopted:
the 1 high-temperature resistant heat insulation layer is made of a lightweight aluminum silicate refractory castable capable of tolerating 900 ℃, and the refractory castable has certain heat insulation and avoids the heat-resistant groove frame carrying the lightweight aluminum silicate refractory castable from being heated to be over-temperature.
2 before collecting the high-temperature material, paving a semi-wet material with a certain thickness on the heat exchange surface, wherein the semi-wet material is formed by adding water into the cooled high-temperature material (the same material as the molten powder), and the water content of the semi-wet material is determined according to production requirements.
Semi-wet material function:
(1) the high-temperature materials are scattered on the semi-wet materials, so that the high-temperature materials are prevented from directly contacting the movable conveying surface.
(2) The high-temperature materials are scattered on the semi-wet base material layer, the moisture of the semi-wet base material layer is evaporated, the temperature rising speed of the heat exchange surface is delayed, and the heat exchange surface is protected.
The moisture content of the semi-moist primer layer ensures that the temperature at which the transfer surface is delayed from leaving the spray chamber does not exceed the service temperature of the heat-resistant cast iron.
3) The refractory grate type movable material conveying surface (heat exchange surface) structurally separates stress and heated elements: the driving chain is arranged below the fire grate, and the upper surface of the fire grate is arranged on the upper surface of the fire grate and separates the high-temperature material from the driving chain. The driving chain is not directly heated by high-temperature materials, but the driving chain drives the fire grate and the materials on the fire grate to move under the action of the driving motor and the speed reducer, so that the fire grate is fixed between the driving chains and moves along with the driving chains, and receives the heating of the high-temperature materials but has small stress.
4) And a cooling water pipe accompanied is arranged below the driving chain, and the temperature of the driving chain is reduced through radiation heat exchange so as to recover low-temperature waste heat of the driving chain for heating.
The working process of the invention is as follows:
slag droplets obtained after gas quenching of blast furnace slag are sprayed into the shell 7 through the molten powder spraying inlet 6, the slag droplets are solidified in the air to form a high-temperature material 10, gas quenching waste gas is discharged out of the shell 7 through the high-temperature waste gas outlet 11, and the high-temperature material 10 is conveyed to a discharge hole on the heat exchange surface 8.
The heat-resistant slot frame 17 is penetrated into the holes on the closed chain by the shafts 18 at the two ends of the heat-resistant slot frame, and the closed chain is hidden under the heat-resistant slot frame 17. The high-temperature-resistant heat insulation layer 15 is inlaid in the groove of the heat-resistant groove frame, so that the temperature of the heat-resistant groove frame 17 is reduced, the strength of the heat-resistant groove frame 17 is improved, and the heat dissipation loss of the lower surface of the collecting and transporting device is reduced. Because the heat-resistant groove frame 17 separates the high-temperature material 10 from the closed chain, the closed chain is only stressed and not directly heated, so that the strength of the closed chain is ensured, and the heat-resistant groove frame 17 is only heated and not stressed. When the heat exchange surface 8 moves forwards and enters the shell 7, a semi-wet bottom material layer is paved on the surface of the heat exchange surface 8, and the semi-wet bottom material layer has the effects of separating high-temperature powder from the high-temperature resistant heat insulation layer 16 and the heat-resistant groove frame 17, reducing the working temperature of the high-temperature powder and the heat-resistant heat insulation layer, improving the strength of the high-temperature powder and the heat-resistant heat insulation layer and reducing the heat dissipation loss of the high-temperature powder and the heat-resistant heat insulation layer. The semi-wet base material layer is prepared by adding water after cooling high-temperature powder, and the water adding amount is determined according to production requirements. The thickness of the semi-wet bottom material is regulated by a flashboard positioning height regulating structure 4 and a flashboard 3, and the semi-wet bottom material layer is contained in a hopper 5. The water-cooled tube 12 is arranged at the lower part of the closed chain, reduces the temperature of the closed chain through radiation heat exchange, and uses the absorbed residual heat of the closed chain for heating in a factory. The grate guide rail 14 is a chain guide rail, and mainly supports the lower chain to avoid breakage due to the excessive weight of the chain.
The foregoing has described exemplary embodiments of the invention, it being understood that any simple variations, modifications, or other equivalent arrangements which would not unduly obscure the invention may be made by those skilled in the art without departing from the spirit of the invention.
