Abstract
The utility model discloses a vertical air heating furnace by ribbed tube heat-exchange which provides hot air to a grain drying machine. A finned heat exchanger is formed by heat exchange tubes which are staggered, an upper grid and a bottom grid. Compared with the similar products, the utility model has the advantages of small volume, light weight, low cost, long service life, easy replacement, high thermal efficiency, large heat exchange area, high hot air temperature, etc. The utility model is matched with the grain drying machine.
Description
The utility model belongs to the grain drying technical field, is a kind of supporting finned tube heat exchange vertical hot furnace of foodstuff drying device that is used for.
At present, used hot-blast stove, no matter be horizontal or vertical, its heat exchanger all is to adopt to weld rectangular lath on the steel plate or make promptly so-called transverse tube type hot-blast stove with the light steel pipe bundle.In order to satisfy needed heat exchange area, required sheet material and tubing quantity are all very big, seem heavy, and hot blast temperature is not high or burn out hot-blast stove.About about 120 ℃ of general hot-blast stove output hot blast temperature, can not satisfy the needs of foodstuff drying device far away, and service life is about 1 year, that have even must repair weldering once in one, two month, it is low to be sought after a kind of cost, life-span is long, can satisfy the hot-blast stove of stoving process requirement, and is supporting with grain drier.
The purpose of this utility model provides that a kind of cost is low, the life-span is long, change conveniently, can satisfy the finned tube heat exchange vertical hot furnace of stoving process requirement.
The utility model is achieved in that hot-blast stove is made up of body of heater, finned heat exchanger, furnace top cover.Bottom of furnace body has the stove seat, fire bars, burner hearth, its inner block has refractory brick, furnace body outer wall has insulation material, the hot blast chamber is between inboard wall of furnace body and furnace body outer wall, flange is connected between body of heater and the finned heat exchanger, staggered aliform radiating tube is arranged in the finned heat exchanger, its two ends and upper face plate and lower face plate welding, the finned heat exchanger interposition is equipped with deflection plate, deflection plate top one side has cold air inlet, deflection plate bottom one side has air outlet, and lower face plate bottom outer wall has air inlet, and burner hearth passes through lower face plate, the finned heat exchanger endoporus, upper face plate is communicated with the furnace top cover outlet flue.
The utility model has the advantages that, reasonable in design, thermal efficiency height, heat exchange area is big, the hot blast temperature height, body of heater can change, and is easy to maintenance, long service life, the consumption steel material is few, and cost is low.
Below in conjunction with accompanying drawing structure of the present utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model finned heat exchanger sectional drawing.
Label is described as follows among Fig. 1 and Fig. 2:
1, fire bars; 2, fire door; 3, insulation material; 4, refractory brick; 5, flange; 6, fin heat exchange pipe; 7, deflection plate; 8, cold air inlet; 9, heat exchanger; 10, furnace top cover; 11, outlet flue; 12, hot-blast outlet; 13, stove seat; 14, outer wall; 15, inwall; 16, hot blast chamber; 17, body of heater; 18, lower face plate; 19, upper face plate; 20, air outlet; 21, air inlet.
Hot-blast stove shown in Figure 1 is made up of body of heater, finned heat exchanger and furnace top cover, can change between them.Bottom of furnace body has stove seat 13, fire bars 1, build in the burner hearth refractory brick 4 is arranged, furnace body outer wall 14 has insulation material 3, hot blast chamber 16 is between inboard wall of furnace body 15 and furnace body outer wall 14, flange 5 is connected between body of heater 17 and the finned heat exchanger 9, there is staggered aliform radiating tube 6(to see Fig. 2 in the finned heat exchanger 9), its two ends and upper face plate 19 and lower face plate 18 welding, finned heat exchanger 9 interpositions are equipped with deflection plate 7, and deflection plate 7 tops one side has cold air inlet 8, and deflection plate 7 bottoms one side has air outlet 20, lower face plate 7 bottom outer walls have air inlet 21, burner hearth is by lower face plate 19, finned heat exchanger endoporus, upper face plate 18 and furnace top cover 10, outlet flue 11 is communicated with.
The utility model can make the blower fan air blast enter cold air inlet, through the coal-fired heat that produces of fast Absorption, be heated to temperature required, the hot blast flow direction is to enter cold wind by cold air inlet 8, through finned heat exchanger 9 heat absorptions, flow to air outlet 20 by deflection plate 7 one ends, enter air inlet 21, and enter hot blast chamber 16, enter the foodstuff drying device inlet by hot-blast outlet 12.The high-temperature flue gas that coal combustion produces in the burner hearth after the fin heat exchange pipe endoporus flows into, passes heat exchanger tube, is discharged by outlet flue.
Heat exchanger employing seamless steel pipe outer wall of the present utility model is loaded onto with the Round fin of punch press punching out or is adopted certain processing technology that slim steel strip winding is formed fin at the seamless steel pipe outer wall. This fin heat exchange pipe has increased heat exchange area greatly, and does not increase the hot-blast stove volume, compare its all technical with domestic like product all to take the lead, and be very good hot-blast stove.
The utility model is applicable to provides hot blast for foodstuff drying device is supporting.
