Abstract

The utility model provides a drying tower, which mainly comprises an air inlet, a rectifier, a drying chamber, etc., wherein, the rectifier is arranged below the air inlet and above the drying chamber, and is composed of a plurality of blocks of rectifying plates perpendicular to a horizontal plane; the rectifying plates can be plane plates or curved plates, and the projection of each rectifying plate on the horizontal plane is a straight line or a curved line; the flat plate and the curved plate or the curved plate and another curved plate are welded together on a contact line to form a plurality of vertical through holes which have small cross-section area and are isolated from each other. The utility model has the advantages of little rectifying resistance and little energy consumption.

Description

Drying tower

The utility model relates to a kind of drying tower that is used on the drying equipment.

The drying tower that generally uses mainly comprises air inlet at present, rectifier, drying chamber, rectifier is located at below the air inlet, above the drying chamber, the hot blast of coming in from air inlet steadily and equably flows in drying chamber from top to bottom through the axis that makes hot blast can be parallel to drying tower with rectification of dividing equally of rectifier, rectifier wherein is the sieve-board type structure, promptly horizontal with interval from top to bottom by some corrosion resistant plates, be drilled with many vertical through hole on the every corrosion resistant plate, hot blast is divided equally and rectification by promptly having realized from the vertical through hole of a piece corrosion resistant plate, the drying tower of this structure makes resistance bigger because the percent opening of rectifier is low, and energy loss is relatively gone through evil.

The purpose of this utility model provides the drying tower that a kind of rectification resistance is little, energy loss is little.

To achieve these goals, technical solution of the present utility model is such: drying tower mainly comprises air inlet, rectifier, drying chamber etc., rectifier is located at below the air inlet, above the drying chamber, wherein, rectifier is made of the many cowling panels vertical with horizontal plane, cowling panel can be surface plate or curved slab, the every projection of cowling panel on horizontal plane is straight line or curve, and surface plate and curved slab or curved slab and another curved slab are welded together to form the vertical through hole of the less mutual isolation of many cross-sectional areas each other on contact wire.

Because in the above-mentioned technical solution, rectifier is made of the many cowling panels vertical with horizontal plane, cowling panel is welded together to form many vertical through hole, the percent opening of this rectifier is than higher, and the drying tower that therefore this technical solution provided has the effect that the rectification resistance is little, energy loss is little.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is the structural representation of drying tower.

Fig. 2 overlooks the structure for amplifying schematic diagram for rectifier.

Fig. 3 is that the A of Fig. 2 is to view.

Wherein: 1. air inlet; 2. rectifier; 3. drying chamber; 4. surface plate; 5. curved slab; 6. contact wire; 7. vertical through hole.

As shown in the figure, drying tower mainly comprises air inlet 1, rectifier 2, drying chamber 3 etc., rectifier 2 is located at below the air inlet 1, above the drying chamber 3, wherein rectifier 2 is made of the many cowling panels vertical with horizontal plane, cowling panel comprises 5 two kinds of surface plate 4 and curved slabs, the every projection of cowling panel on horizontal plane is straight line or curve, curved slab 5 is at the curve that is projected as a zigzag of horizontal plane, a jagged curved slab 5 is close in the both sides of every surface plate 4, a surface plate 4 is close in the both sides of every jagged curved slab 5, surface plate 4 and jagged curved slab 5 weld together on contact wire 6, surface plate 4 and jagged curved slab 5 form the vertical through hole 7 that many cross-sectional area small cross section are shaped as equilateral triangle, the vertical through hole 7 that hot blast is sent to through rectifier 2 from air inlet 1 in the drying tower use arrives drying chamber 3, hot blast from many vertical through hole 7 of rectifier 2 by the time divided equally and rectification, because the percent opening of the rectifier 2 that is made of cowling panel is obviously than in the past rectifier height, thereby has tangible rectification resistance force diminishes, the effect that energy loss reduces.

In the embodiment previously described; if the shape of cowling panel is done some changes; as long as it is vertical with horizontal plane that cowling panel keeps; the projection of cowling panel on horizontal plane is straight line or a curve; by surface plate 4 and curved slab 5 or on contact wire 6, be welded together to form the vertical through hole 7 of the less mutual isolation of many cross-sectional areas each other by curved slab 5 and another curved slab 5; then the embodiment that is constituted after the change still comprises the essential features of the utility model independent claims; and can realize the utility model purpose, also belong to the desired protection domain of the utility model.
