An upper air chamber (15) is arranged at the upper part of a drying cabinet (1), and a lower air chamber (14) is arranged at the lower part. The upper air chamber (15) is provided with an upper air inlet opening (19) and an upper air outlet opening (13). The lower air chamber (14) is provided with a lower air inlet opening (18) and a lower air outlet opening (12). A multi-layered orifice plate flat bed (16) is arranged at the middle part of the drying cabinet (1). An upper air gate (3), feeding and discharge gates (2), a lower air gate (4) are arranged at the front of the drying cabinet (1) and behind the drying cabinet (1). An air collecting chamber (11) is arranged between the hot blast stove (5) and the drying cabinet (1). A vertical smoke tube bank heat exchanger (9) is arranged above a combustion chamber (7) of the hot blast stove (5). The upper end of a heat exchange air chamber (10) is connected with a centrifugal air blower (6). The lower end of the heat exchange air chamber (10) is connected with the air collecting chamber (11), and is also connected with the drying cabinet (1), the lower end of the tube bank of the vertical smoke tube bank heat exchanger (9) and the upper end of a fire box wall calandria tube (8) are respectively fixed at the upper part and the lower part of the top part orifice plate of the combustion chamber (7). The upper end of the vertical smoke tube bank heat exchanger (9) is connected with a chimney (20).

Description

The symmetry drying cabinet inserts and puts the integrated dryer of hot-blast stove

Technical field

The utility model belongs to agricultural byproducts processing, particularly agricultural byproducts oven dry mechanical field

Background technology

Traditional flat bed dryer is that baking oven and hot-blast stove are arranged apart, must be connected by air pipe line, smoke pipe road to assemble, and occupation of land is big, cost is high, heat loss is many.

When intermittently drying wet stock, hot blast if folk prescription to wet stock heat exchange precipitation, the material after the oven dry is inhomogeneous, if adopt the wet stock flow circuit, though can improve the uniformity, increases the fragmentation of material.

Summary of the invention

The utility model mainly solves hot-air flow commutation and carries wet precipitation with the wet stock heat exchange, reach material static, not broken, dry uniform purpose.Also to solve because of pipeline between baking oven and the hot-blast stove and connect problems many, that heat loss is many, occupation of land is big, cost is also high.

The technical scheme of dealing with problems is:

Insert and put hot-blast stove 5 in the middle of the drying cabinet 1 of two symmetries.Ipper air chamber 15 is arranged at oven dry torch 1 top, and lower air chamber 14 is arranged at the bottom.There are last air inlet 19 and last air outlet 13 in ipper air chamber 15.There are following air inlet 18 and following air outlet 12 in lower air chamber 14.There is multilayer orifice plate level bed 16 at drying cabinet 1 middle part.There is upper wind door 3 front and back of drying cabinet 1, and turnover bin gate 2 is arranged, and lower wind door 4 is arranged.

Between hot-blast stove 5 and the drying cabinet 1 wind assembling set 11 is arranged.There is perpendicular smoke pipe bundle heat exchanger 97 tops, combustion chamber of hot-blast stove 5.10 upper ends, heat exchange wind chamber and centrifugal blower 6 link.10 lower ends, heat exchange wind chamber lead to wind assembling set 11, also logical drying cabinet 1.Erect the tube bank lower end of smoke pipe bundle heat exchanger 9 and the upper end of fire box wall comb 8, be separately fixed at the above and below of combustion chamber 7 top orifice plates.The upper end UNICOM chimney 20 of perpendicular smoke pipe bundle heat exchanger 9.

This symmetrical drying cabinet inserts and puts the hot-blast stove 5 of the integrated dryer of hot-blast stove, the perpendicular smoke pipe bundle heat exchanger 9 and the fire box wall comb 8 of full counter heat convection have been used, after adding hot-air with the higher thermal efficiency, to being still in the wet stock 17 in the drying cabinet 1, after wet precipitation is carried in the enforcement heat exchange, utilize the Push And Release of upper wind door 3 and the Guan Yukai of lower wind door 4 again, transposing hot blast direction.Dry material 17 moisture content that reach after the oven dry are even, and chip-proof purpose.Because hot-blast stove 5 is integrated with drying cabinet 1, no pipeline connects, and reaches compact conformation, takes up an area of for a short time, and heat loss is few, and SR is little, and equipment manufacturing cost is low, and it is low to dry cost, Operation and Maintenance and good result.

Description of drawings

Embodiment further specifies the utility model below in conjunction with accompanying drawing.

Figure of description is a three-plane projection of the present utility model schematic diagram.Front view has adopted partly and has cutd open, side view broken section hot-blast stove 5 and drying cabinet 1, and vertical view has adopted partly and has cutd open.

Specific implementation method

Open turnover bin gate 2, will the multilayer orifice plate level bed 16 of wet stock 17 be housed, the drying cabinet 1 of all packing into is closed turnover bin gate 2 tight.

The bavin coal is added combustion chamber 7, light stove fire, heat heating fire box wall comb 8 and perpendicular smoke pipe bundle heat exchanger 9 that combustion bavin coal produces, useless flue gas is discharged from chimney 20.The centrifugal blower 6 malleations into heat exchange wind thorax 10 of blowing a cold wind over and has improved temperature after perpendicular smoke pipe bundle heat exchanger 9 heat exchange, continues heat exchange with fire box wall comb 8 again, improves to enter wind assembling set 11 after reaching temperature.When upper wind door 3 was set up on opening air inlet 19 positions, last air outlet 13 was also closed.Lower wind door 4 is set up when closing air inlet 18 positions, and following air outlet 12 is also open-minded.At this moment, the hot blast through hot-blast stove 5 heating enters wind assembling set 11, advances uptake 19, advance after the ipper air chamber 15 can only be from top to bottom with multilayer orifice plate level bed 16 on wet stock 17 carry out heat exchange and carry wet precipitation after, enter lower air chamber 14, discharge from air outlet 12 down.

Hot blast commutation: when upper wind door 3 was set up on closing air inlet 19 positions, last air outlet 13 was also open-minded.Lower wind door 4 is set up when opening air inlet 18 positions, and following air outlet 12 is also closed.At this moment, after hot blast enters wind assembling set 11, advance air inlet 18 down, enter lower air chamber 14, can only be from bottom to top with multilayer orifice plate level bed 16 on wet stock 17 carry out heat exchange again and carry wet precipitation after, enter ipper air chamber 15 and discharge from last air outlet 13.The dry material 17 that oven dry is good takes out from turnover bin gate 2.
