Description
Technical field
The utility model relates to the tunnel-kiln type drying machine structure that a kind of preheating heats, and is specifically related to a kind of tunnel drier, and this machine can be widely used in the large grain of agricultural product nut dries (for example: the larger materials of the gradation of moisture such as walnut, chestnut, peanut).The utility model belongs to Drying Technology of Agriculture Products field.
Background technology
In tunnel cave drying system, current common way is one end air intake, other end air-out, or following current, or adverse current, and above way is fine to the drying effect of general vegetables, edible mushroom, but this mode is but very low to drying nut efficiency.If adopt two ends air intake mode, higher to heat source system configuration requirement, should not realize, and increase larger cost.The dry feature of large grain nut is that the preheat temperature of nut inside just starts from inner hydrofuge while rising to 45～52 DEG C, and excess Temperature will affect materials quality, and it's the end is past temperature will make prolongation drying time.The drying efficiency of drying nut if improve must be promoted to 45～52 DEG C by material internal temperature as early as possible, carries out afterwards heated-air drying again.
Summary of the invention
The utility model for overcoming the above problems adopted technical scheme is:
A kind of tunnel drier that heats structure with preheating comprises hot-blast stove 1, the drying kiln body 11 being connected with described hot-blast stove 1 by warm-air pipe 3, in the arrival end of described drying kiln body 11, be provided with one section of heat exchanger 8, the exhaust opening of described hot-blast stove 1 is connected with described heat exchanger 8 by drawing cigarette blower fan 4.
Above-mentioned heats in the tunnel drier of structure with preheating, and described heat exchanger 8 is for being located at the heat exchanger of both sides band heat exchange fin in 5～7 meters of length of drying kiln body 11 entrance.
Above-mentioned heats in the tunnel drier of structure with preheating, the described cigarette blower fan 4 that draws is connected with a sootfall case 6 by airduct I 5, the outlet of this sootfall case 6 is connected with described heat exchanger 8 by airduct II 7, connected in series or in parallel by airduct III 9 between heat exchanger 8, heat exchanger 8 is communicated with chimney 10.
Above-mentioned heats in the tunnel drier of structure with preheating, and described hot-blast stove 1 is provided with air blast 2 and warm-air pipe 3, and the other end of this warm-air pipe 3 is connected with the air intake of drying kiln body 11, and described drying kiln body 11 is provided with side door 12.
Above-mentioned heats in the tunnel drier of structure with preheating, described warm-air pipe 3, and airduct I 5, sootfall case 6 and airduct II 7 are all incubated, and they are all with lagging facility, to reduce heat loss.
The beneficial effects of the utility model are: meet bulky grain nut drying materials characteristic, improved the drying efficiency of bulky grain nut material, take full advantage of fume afterheat, saved the energy.

In above accompanying drawing: 1. hot-blast stove, 2. air blast, 3. warm-air pipe, 4. draw cigarette blower fan, 5. airduct I, 6. sootfall case, 7. airduct 2,8. heat exchanger, 9. airduct III, 10. chimney, 11. drying kiln bodies, 12. side doors.
Detailed description of the invention
As shown in Figure 1, this tunnel drier that heats structure with preheating by hot-blast stove 1, air blast 2, warm-air pipe 3, draw cigarette blower fan 4, airduct I 5, sootfall case 6, airduct II 7, heat exchanger 8, airduct III 9, chimney 10, drying kiln body 11, side door 12 and form.In the present embodiment, hot-blast stove 1 is indirect coal-fired hot-blast stove, and the thermal source that it is this dryer provides uniform temperature a certain amount of hot-air, and hot-air is sent into drying kiln body one end through warm-air pipe 3 under the effect of air blast 2.The flue gas of indirect coal-fired hot-blast stove blasts sootfall case 6 through the effect of drawing cigarette blower fan 4 by airduct I 5, flue gas after sootfall enters heat exchanger 8 by airduct II 7, the heat exchanger 8 of multi-group heat exchange fin is realized serial or parallel connection by airduct III 9, and flue gas goes out heat exchanger 8 and enters chimney 10 and discharge.
Heat exchanger 8 with heat exchange fin is installed entering length drying kiln body 11 interior both sides, 5～7 meters of car one end, in heat exchanger 8, pass into flue gas, through heat exchange, make the space of 5～7 meters long of feed ends form the preheating section of 50～70 DEG C of temperature environments, material, this section heated intensification rapidly, was warming up to 45～52 DEG C at 5～6 hours by material.Temperature of charge rises to 45～52 DEG C of heels and pushes the heated-air drying section of drying kiln body 11 with drying car.
Air enters from the air intake of drying kiln body 11 through the air blast 2, the burner hearth of indirect coal-fired hot-blast stove, the warm-air pipe 3 that are positioned at indirect coal-fired hot-blast stove top, the B direction from drying kiln body 11 side door 12(Fig. 2) discharge.
Dry car and enter from A mouth, go out from C mouth.Drying car normally moves according to material situation.
The utility model adopts mounting heat exchanger on 5～7 meters of inner side walls of feed end drying kiln body, passes into flue gas in heat exchanger, through heat exchange, makes the space of 5～7 meters long of feed ends form the temperature field of 50～70 DEG C, by rapid material heat temperature raising.Material was warming up to 45～52 DEG C at preheating section through 5～6 hours, and now material starts a large amount of hydrofuges.Afterwards, material is followed baking car and is continued to push ahead, and enters the ventilation drying section of drying kiln body, dries, until by drying materials under 40～60 DEG C of wind-warm syndrome states.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
