Background technology
In the production technology of aluminium foil, annealing is one of important step in its Technology for Heating Processing, lehr attendantSkill comprises intensification, is incubated, lowers the temperature several stages. In prior art, the annealing device of aluminium foil mainly adoptsTraditional box-annealing furnace, box-annealing furnace only has a furnace cavity, by all aluminium foils be deposited in interior afterSlowly be warming up to assigned temperature, slow cooling after insulation a period of time; After being down to normal temperature, all aluminium foils are pushed awayGo out, and after furnace chamber is completely cooling, carry out again the intensification of next stove; The whole cycle needs 3-5 days time.
In temperature-rise period, there is following shortcoming in box-annealing furnace:
1, the intensification of box-annealing furnace, insulation, temperature reduction technology carry out in a burner hearth, and the annealing cycle is long;
2, box-annealing furnace capacity is large, and in temperature-rise period, heat demand amount is large, serious heat loss;
3, box-annealing furnace capacity is large, and in temperature-rise period, Diffusion of gas stream is inhomogeneous, and aluminium foil is heated inhomogeneous,The efficiency of heating surface is low, and ROLLING OIL volatilization is not thorough.
4, box-annealing furnace capacity is large, and airduct is arranged in structure in the stove complexity, body of heater high material consumption.
Summary of the invention
The object of the invention is in order to overcome above shortcoming, provide one effectively to utilize thermal source, raising addsThe body of heater of the continuous annealing furnace of the thermal efficiency.
Technical scheme of the present invention is:
A body of heater for continuous annealing furnace, described body of heater is connected to form by several independent bodies of heater, and adjacent twoBetween individual independent body of heater, disconnected by fire door, described each independent body of heater comprises furnace body skeleton and is arranged on skeletonThe seal closure in outside, described seal closure is hollow, the two ends of described body of heater are provided with seal closure and are connectedDescribed fire door, on the seal closure of described each independent body of heater, be provided with blast pipe and exhaust duct, described in enterAirduct is connected with air-heater exhaust outlet and air inlet respectively with exhaust duct, and described blast pipe and exhaust duct are respectivelyBe communicated with discharge pipe in stove and backwind tube, described discharge pipe and backwind tube are respectively described furnace body skeleton extremelyA few support column, described discharge pipe is not connected with described backwind tube, and described discharge pipe and backwind tube areOn surface, be provided with the hollow tube in several wind holes, the bottom of described furnace body skeleton is provided with guide rail briquetting.
Further, described each independent body of heater is communicated with an air-heater.
Further, the lower horizontal support post that described discharge pipe is furnace body skeleton, described backwind tube is stoveThe upper level support column of body skeleton.
Further, the length direction of described discharge pipe and the length direction of described backwind tube are vertical.
Further, described wind hole is arranged on the both sides of described discharge pipe and backwind tube horizontal direction, processThe air-flow of described wind hole direction is vertical with vertical direction.
Further, the bottom of described each independent body of heater is provided with negative-pressure air duct, described negative-pressure air duct withNegative-pressure air fan connects.
Further, described negative-pressure air duct is rectangular tube, and the upper surface of described negative-pressure air duct is provided with someIndividual wind hole.
Further, the diameter in described wind hole is 5-15mm.
Further, between described furnace body skeleton and seal closure, heat-insulation layer is set.
Further, the top of the seal closure of described each independent body of heater and the bottom of described seal closure are for livingBe dynamically connected, described joint face arrives between the heat-insulation layer of top at 3/4 of furnace body skeleton height.
The body of heater of continuous annealing furnace provided by the invention, has the following advantages:
1, aluminium foil is heated evenly, and heating efficiency is high. Body of heater in continuous annealing furnace is independent by severalBody of heater composition, is separated by fire door between each independent body of heater, and the hot blast that air-heater provides enters respectively eachIndependent body of heater heats up gradually aluminium foil in body of heater, and in stove, aluminium foil is heated evenly, and ROLLING OIL volatilization completely;The scope relative decrease of Hot-blast Heating in single body of heater, heat is more concentrated, thereby has improved the utilization of hot blastEfficiency.
2, shorten annealing furnace heating cycle. Btu utilization in single body of heater is abundant, and the efficiency of heating surface improves,Thereby shorten the heat time to aluminium foil in each independent body of heater, body of heater is heated to be continuity operation, therebyShorten whole heating cycle.
3, in body of heater, hot-air flow is stable, even, and aluminium foil is heated evenly. Discharge pipe is arranged on the end of body of heaterPortion, backwind tube is arranged on the top of body of heater, and the interior thermal cycle forming in body of heater, makes hot-air at body of heaterInterior air-flow is more stable;
Discharge pipe length direction is vertical with backwind tube length direction, makes the air-flow flowing out from the wind hole of discharge pipeDirection is vertical with the airflow direction in wind hole that enters backwind tube, in body of heater, increased inner air circulationPath, the time of staying of air-flow in body of heater increases, thereby reduced the heat time of aluminium foil; Meanwhile,Increase the flow path of air-flow, made Diffusion of gas stream to whole body of heater, gas stream in the stove good uniformity;
The wind hole of discharge pipe and backwind tube is arranged on the both sides of airduct, and hot blast spreads in body of heater, has avoidedAir-flow directly impacts aluminium foil, affects the performance of aluminium foil, and meanwhile, air-flow in the horizontal direction and verticallyDirection flows, and in body of heater, air-flow is even, temperature stabilization, thus aluminium foil is heated evenly, stable performance.
4, the ROLLING OIL that in body of heater, aluminium foil volatilizes is got rid of thoroughly. The bottom of body of heater is provided with negative tube, negativePressure pipe is connected with negative-pressure air fan, and in body of heater, aluminium foil is heated to after uniform temperature, volatilizes ROLLING OIL, negativeUnder the effect of pressing, ROLLING OIL is discharged body of heater, ensures the cleanliness factor of air in body of heater, avoids aluminium foil to causeSecondary pollution.
5, body of heater inner structure is simple, reduces the consumable quantity of body of heater. Because furnace body skeleton uses as airduct, stoveIn body, independently add warm-air pipe without installing, reduced the consumable quantity of body of heater, furnace body skeleton is meeting structureUnder the prerequisite of intensity, hot blast is incorporated in body of heater, heating aluminium foil is to uniform temperature.
