Abstract
The utility model relates to a double-layer casing structure which is additional provided with a layer of thin steel plate or aluminium plate outside a furnace casing to form a closed air layer.
Description
The utility model relates to a kind of industrial furnace double-deck furnace shell structure, belong to metallurgical class industrial furnace design field.
Industrial furnace is widely used in metallurgy, casting, industries such as heat treatment and forging.Its energy consumption accounts for more than 80% of hot-working special manufacturer.Improve the thermal efficiency of industrial furnace, reduce energy resource consumption, the life-span that prolongs stove is one of industrial furnace problem of wanting the emphasis solution.For saving the energy, the protection environment effectively utilizes existing resource, is necessary industrial furnace is carried out reducing energy consumption.The general industry stove only wraps one deck steel plate outside furnace lining, this layer steel plate also has sealing to reduce the effect of stove heat loss except playing the effect of protection furnace lining.But the furnace surface temperature of one deck furnace shell is still higher, and heat loss is bigger, causes work under bad environment simultaneously.If only reduce the method for radiation loss by the thickening furnace lining, can increase the accumulation of heat loss of furnace lining again, can not reduce fire box temperature for the stove of the cooling that requires to heat up repeatedly rapidly because of furnace lining is too thick, reduce operating efficiency.Increase one deck shell outside industrial furnace an air-gap is set, this structure does not increase lining thickness but can reduce radiation loss, can solve the contradiction of rapid cooling again simultaneously, enhances productivity.Analyze by prior art documents, do not find the relevant report of this theme as yet.
The purpose of this utility model is to overcome deficiency of the prior art, proposes a kind of industrial furnace double-deck furnace shell structure, has obtained energy-saving effect preferably.
The technical solution of the utility model is as follows: the furnace lining of existing industrial furnace has only one deck steel plate outward, and the utility model structure is for installing one deck sheet metal or aluminium sheet additional outside furnace shell, links to each other with bolt or other modes between two-layer, has formed the double-deck furnace shell structure.The surface temperature of stove further reduces, and reduces heat loss.In double-deck furnace shell inboard or the outside paste one deck refractory fibre, better effects if.Also can the bottom of double-deck furnace shell and above be installed as movable cover plate, when heating and insulation, close loam cake and lower cover, the double-deck furnace hull shape becomes the occluded air layer, reduce heat loss, and when cooling off, open by needs upper and lower covers, quicken cross-ventilation and accelerate cooling, the utility model is applicable to the industrial furnace of the cooling that need heat up repeatedly.As gas carbruizing furance, temperature higher (about 930 ℃) requires high insulating effect during carburizing, and carburizing finishes the interior temperature of back stove will drop to hardening heat (about 860 ℃), requires to accelerate heat radiation in this stage.Adopt the utility model can better solve heat tracing stage and the different requirements of temperature-fall period, greatly enhance productivity the furnace wall heat radiation.Also can be on body of heater with plate sheet welding, make double-deck furnace shell become the watertight cavity of sealing, two ends are installed into water pipe and outlet pipe up and down, the external cooling water in upper end, the lower end draining, water valve is installed at two ends respectively up and down, and heating process drains the water in the cavity, close the two ends valve, the occluded air layer in the chamber plays the effect of heat-insulation and heat-preservation.When needing cooling, open water valve up and down, inject cooling water, the water leg of cavity below band gradient compiles water, discharges by the drainpipe of bottom.Water can recycle use after cooling, if cooling velocity is not too fast or no-cooling-water, can two ends be installed by breather valve respectively up and down at stove, and external air blast is blown into the cold air cooling without cooling water with the air blast brute force during cooling.
The utlity model has very high practical value, improved energy-saving effect significantly, reduce radiation loss 10%.Especially the industrial furnace that heats up repeatedly for need and lower the temperature repeatedly can reduce heat loss when heating up, can lower the temperature rapidly again when cooling, obviously improves the work efficiency of heating furnace, adopts the utility model also can obtain similar effect to other kinds discontinuous running stove.
Further describe below in conjunction with accompanying drawing:
The double-deck furnace shell schematic diagram of Fig. 1 splint fixation formula.
The board-like double-deck furnace shell of Fig. 2 removable cover schematic diagram.
The double-deck furnace shell schematic diagram of Fig. 3 water cooling.
Fig. 4 air cools off double-deck furnace shell schematic diagram
Shown in Fig. 1,2,3 and 4, the utility model structure is for installing one deck sheet metal or aluminium sheet 2 additional existing furnace shell 1 outside, two-layer between usefulness bolt 3 or other modes continuous, formed the double-deck furnace shell structure of occluded air layer.In double-deck furnace shell inboard or the outside paste one deck refractory fibre 4 better effects if.Lower cover 8 is installed in the bottom 5 of double-deck furnace shell and cover plate 7 is installed in top 6, upper cover plate 7 and lower cover 8 are movable cover plate, close upper cover plate 7 and lower cover 8 when heating and insulation, the double-deck furnace hull shape becomes the occluded air layer, and this form is applicable to the industrial furnace of the cooling that need heat up repeatedly.Sheet metal or aluminium sheet 2 are welded on the body of heater, and double-deck furnace shell becomes the watertight cavity of sealing, and two ends are installed into water pipe 9 and outlet pipe 10 up and down, the external cooling water in upper end, and the lower end draining, water valve 11 is installed at two ends up and down.Also can two ends be installed by breather valve 12, external air blast up and down at stove.
