Described dividing plate is respectively equipped with multiple air intake through hole along cloth throughput direction and the horizontal direction perpendicular to cloth throughput direction;
It is characterized in that: the cross sectional shape of described dividing plate and described enter the broken line shape of cloth rewinder roll, draw-out roller, fabric guide roll height line match, described air intake through hole is axially perpendicular to place place septum plane.
Preferably, the dryer that described cloth flatness is high also comprises to be located at outside described housing, connects the subsidiary conduit of described housing bottom and air outlet.
Preferably, the dryer that described cloth flatness is high comprises two described dividing plates, and two dividing plates are located between described distribution conveyor structure and housing bottom respectively, and between described distribution conveyor structure and case top.
Preferably, air dry-set is provided with in described subsidiary conduit.
Preferably, the dryer that described cloth flatness is high comprises two symmetrically arranged described subsidiary conduits.
Preferably, the sectional area of described subsidiary conduit is the 1/5-1/3 of described air inlet sectional area.
Preferably, described air outlet is only communicated with described two subsidiary conduits respectively, and the sectional area of each subsidiary conduit is the half of air outlet sectional area.
Preferably, air blast is provided with in described subsidiary conduit one end close to described air outlet.
The invention solves the defect existed in background technology, the dryer that cloth flatness of the present invention is high arranges in cross sectional shape and dryer the dividing plate carrying dry cloth cross sectional shape to coincide in housing cavity, directional stream-guidance is carried out to the hot blast entering housing cavity, make cloth hot blast direction everywhere perpendicular to place place cloth plane, not only keep cloth in dry run and dried flatness, and improve drying efficiency.Can also arrange subsidiary conduit, be recycled by the air trapping of complete for drying cloth with moisture, be reintroduced back to housing cavity, auxiliary fresh hot blast together carries out drying work, saves the energy, raises the efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 2 is the top view of the preferred embodiments of the present invention median septum.
Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1-2, the dryer that cloth flatness of the present invention is high, comprises box-type shell 2, and housing 2 two ends are respectively equipped with into cloth mouth 21 and exit slot 22, and be provided with one end into cloth mouth 21 for entering cloth end, the one end being provided with exit slot 22 is cloth outlet.The bottom of housing 2 is provided with air inlet 4, top is provided with air outlet 6, the air blast 12 that air inlet 4 is provided with heating tube 8 and is positioned at outside heating tube 8, is provided with distribution conveyor structure in housing 2 inner chamber, and laterally extending dividing plate 28.Distribution conveyor structure comprise be positioned at that housing 2 enters cloth end enter cloth rewinder roll 14, be positioned at the draw-out roller 18 of cloth outlet, and be located at into the fabric guide roll 16 between cloth rewinder roll 14 and draw-out roller 18.Enter cloth rewinder roll 14, fabric guide roll 16, draw-out roller 18 laterally to be arranged in parallel, fabric guide roll 16 is positioned at the below into cloth rewinder roll 14 and draw-out roller 18 height and position line, enter cloth rewinder roll 14, draw-out roller 18, fabric guide roll 16 height and position line be broken line.Heating tube 8 is axially parallel to into cloth rewinder roll 14 axially, and air blast 12 just to heating tube 8 upwards.Be provided with between two dividing plates, 28, two dividing plates 28 are located at bottom distribution conveyor structure and housing 2 respectively in housing 2 inner chamber altogether, and between distribution conveyor structure and housing 2 top.The cross sectional shape of every block dividing plate 28 with enter cloth rewinder roll 14, draw-out roller 18, fabric guide roll 16 height and position line broken line shape match.Every block dividing plate 28 is respectively equipped with multiple air intake through hole 24 along cloth throughput direction 1 and the horizontal direction perpendicular to cloth throughput direction 1, and the shape of air intake through hole 24 is circular but is not limited to circle; Air intake through hole 24 is axially perpendicular to place place dividing plate 28 plane.The dryer of the present embodiment also comprises to be located at outside housing 2, connects bottom housing 2 and the subsidiary conduit 26 of air outlet 6.Subsidiary conduit 26 has two, arranges about the plane symmetry perpendicular to cloth throughput direction 1.In subsidiary conduit 26, can air dry-set be set, and auxiliary blower, wherein auxiliary blower is arranged on the one end close to air outlet 6.The sectional area of subsidiary conduit 26 is the 1/5-1/3 of air inlet 4 sectional area, ozone is entered based on air inlet 4, the air that circulation introduced by subsidiary conduit 26 is auxiliary, when the sectional area of subsidiary conduit 26 and air inlet 4 sectional area take above-mentioned proper proportion, the saving of the energy and dry quality can be taken into account preferably.Air outlet 6 is only communicated with two subsidiary conduits 26 respectively, and the sectional area of each subsidiary conduit 26 is the half of air outlet 6 sectional area, makes the flow in two subsidiary conduits 26 equal.
During work, cloth 3 to be dried being entered cloth mouth 21 by the dryer of the present embodiment and enters, laterally successively through entering cloth rewinder roll 14, fabric guide roll 16, draw-out roller 18, stretching out from exit slot 22.Start dryer, cloth 3 is by entering cloth mouth 21 to exit slot 22 transverse movement, while cloth 3 is carried, fresh air outside is pressed into by housing 2 bottom air inlet mouth 4 by air blast 12, heat through heating tube 8, form the dividing plate 28 that hot blast blows to lower floor, undertaken uniform by the air intake through hole 24 on the dividing plate 28 of lower floor, and move upward perpendicular to place place dividing plate 28 plane respectively, penetrate cloth 3 and carry out heat drying, the dividing plate 28 of the hot blast with moisture through upper strata through cloth 3 enters subsidiary conduit 26 respectively by air outlet 6 points of two-way.The guide functions of dividing plate 28, makes cloth 3 hot blast everywhere keep vertical, reduces the loss in other direction, and ensure that cloth 3 is smooth, dryness finalization after avoiding the cloth 3 containing moisture to produce fold and cause end product quality not good.After circulated air enters subsidiary conduit 26, the work of air blast 12 can be utilized to push circulated air downwards, and circulated air sloughs the moisture taken away from cloth 3 in previous drying through air dry-set, reenters housing 2 inner chamber, the drying work of auxiliary fresh air.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to right.
