The outer side of the flue is provided with a sealing cover which is convenient for cleaning smoke dust. The heat supply device for a drying box can be used for heating the air of the drying box for woods, agricultural products, yarns, etc. The utility model has the advantages that heat is radiated fully, the heat is dispersedly and evenly conveyed, the article drying capacity is increased, the utility model slowly dries, the utility model does not cause dried articles to be broken and be fragile, etc.

Description

The drying baker heating plant

The utility model relates to a kind of air heater, is particularly suitable for the heating plant of the drying baker (kiln) of oven dry usefulness such as timber, agricultural product, yarn.

The applicant had once proposed " box drying unit " and " drying baker heat radiation flue " two patent applications respectively in CN97206378.1 and 97213581.2, attain the results expected in application practice.But it is not enough that the radiating effect of the flue of above-mentioned two technology is still disliked, the flow range of hot-air in case (kiln) body is extensive inadequately, concentrated relatively, the drying rate of hot-air are accelerated, and easily cause bad sex change such as oven dry thing cracking, embrittlement, and therefore the effect and the quantity of oven dry are subjected to certain limitation.

The purpose of this utility model is at the deficiency of above-mentioned technology and design a kind of good heat dissipation effect, wide, heating and continuous, even, the slow oven dry of the flow range of hot-air in casing of flue, bad sex change such as the oven dry thing is difficult for ftractureing, embrittlement, the drying baker heating plant that the stacking quantity of oven dry thing increases.

The purpose of this utility model can realize by following measure; It includes the chimney of top, middle sheep-intestines type flue, the body of heater three parts of below, body of heater is made up of grate between the deashing air inlet of the charge door on shell, liner plate and the burner hearth that surrounds thereof, top, bottom and these two mouthfuls etc., be distributed with the tubular louvre vertical with this flue tendency, that open at two ends in the sheep-intestines type flue, there is the capping of being convenient to clear up flue dust and opening and closing as required in the flue outside.

Of the present utility model employing all means available is: burner hearth is bucket shape, and the body of heater shell is square; Grate is double-deck, upper strata high outside and low outside inclination 10-20 degree, and lower floor's level is shelved.

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A cutaway view (amplification) of Fig. 1.

Fig. 3 is the utility model installation site figure in drying baker.

The utility model is described in detail below in conjunction with embodiment: for the square plate of 8-10mm is welded into, liner plate 6 and grate 8 are become by iron casting the shell 10 of body of heater 5 by thick.Be sufficient combustion, grate 8 bilayers, the outer end, upper strata is high inner low, and about 15 degree that tilt are shelved, and lower floor's level is shelved, and is convenient to burn the carbon fire that bavin takes off and burns.Can connect air blast outside the deashing air inlet 9.Firewood drops into from charge door 11, and burner hearth 7 is bucket shape.For easy to make, sheep-intestines type flue 4 is optional thickly to be welded into square tube shape for the 3-5mm steel plate.Horizontal Da Yuan hole, the pipe that open at the two ends that section external diameter equates with this garden bore dia, its length equals the width of flue, with the two ends and the tubular louvre 3 of flue outer wall weldering tightly promptly becoming of this pipe.Certainly, not necessarily to break into the hole, garden, strip, square, streamlined all can, as long as the pipe weldering that is equipped with respective shapes is sternly.But the easy making of garden shape, the purpose in horizontal Da Yuan hole are to make the aperture aligning of tubular louvre 3 to send Hot-air fan 12, so that hot-air is far sent.Chimney 2 optional garden pipes are welded on the flue just can.This heating plant and had one deck can make the wind direction adjusting plate of 180 ° of adjustings between the thing, the outer wind direction regulating handle 13 of casing by baking can regulate as required this plate with give on the hot-air, flat give and under give.There is capping 1 in sheep-intestines type flue 43 outsides, with thick be that the die nut fit sealing of 3-5mm gets final product, open capping 1; Can remove the flue dust in the sheep-intestines type flue.

The densely covered tubular louvre of level in the sheep-intestines type flue of the present utility model, area of dissipation increases greatly, and the Hot-air fan that send that level blows to is arranged, hot-air can be delivered in the more wide casing, good heat dissipation, heat supply dispersion, even have been increased by the accumulating amount of baking thing, realize slowly oven dry, avoid being dried by the fire the explosion embrittlement of thing.

Claims (3)
