Specific embodiment
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.It is to be able to thoroughly understand the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The range opened is fully disclosed to those skilled in the art.
As shown in Figs. 1-2, the disk desiccation machine of preferred embodiment according to the present utility model include: desiccation machine shell,
Hollow shaft 1, disc, sludge inlet 11, sludge outlet 12, steam inlet 13 and water delivery spiral 8.Wherein, hollow shaft 1 is through dry
Change machine shell, hollow shaft are supported by preceding end bearing 6 and rear end bearing 7.Disc is distributed in hollow shaft, and disc is positioned at dry
In change machine shell.Sludge inlet 11 is opened in desiccation machine shell upper, and sludge outlet 12 is opened in desiccation machine outer casing underpart.Steam
Entrance 13 is set to desiccation machine shell side.Water delivery spiral 8 is set to the another of the desiccation machine shell opposite with steam inlet 13
Side.
In above scheme, disc 2 is formed by two panels disk butt welding, inside disc 2 have cavity, cavity be partitioned every
Plate 5 is divided into a plurality of cavities region.It include a long tube 4 and a short tube 3 in each cavity area, long tube 4 and short tube 3 lean on
The nearly partition is arranged, and the long tube in each cavity area is tightly against each other arranged with short tube, the length of short tube and the length of long tube
The ratio of degree is 1:3-1:2.Long tube 3 and short tube 4 both pass through the center line of hollow shaft 1, and the corresponding all pipes of each disk are in axis
To being staggeredly arranged.Preferably, 3 one end of short tube is concordant with 1 outer wall of hollow shaft, and all long tubes 4 are close to subregion partition 5, long tube 4 and short
Pipe 3 is in whole circumference direction interlaced arrangement.Water delivery spiral 8 is welded in water delivery screw outer cylinder 9, and water delivery spiral 8 follows hollow shaft
Rotation.Water vapour is back in hollow shaft 1 from the gap of water delivery spiral 8 and water delivery screw outer cylinder 9.When being limited to disc width
When, partial tube is arranged in same circumferential plane, partial tube avoid being located along the same line to pipe.
Preferably, disk desiccation machine further includes condensation water out 14, and the water vapour for being carried into condensation water out passes through list
Steam inlet 13 is back to valve 10.Long tube and short tube are axially offsetting arrangement, during preventing disk rotational, top circle
The water of disk subregion returns in bottom disc.
The working principle of the utility model is introduced referring to Fig. 3.
In (1) of Fig. 3, when short tube is located at 0 °, short tube and long tube are all more than the liquid level of hollow shaft, and condensed water is not
It can flow backward in disc, short tube continues into vapour, and long tube can also be into vapour before being not yet submerged in disc liquid level or less；When disc gradually turns
When dynamic, long tube is initially as water vapor channel.By 0 ° -180 ° (in order referring to (1)-(2)-(3)-(4) in Fig. 3), this point
Partition board area continues in water inlet steam, and reservoir storage gradually increases, and when being located at (4) position of Fig. 3, disc inner product water reaches most
Greatly, then start to drain；By 180 ° -360 ° (in order referring to (4)-(5)-(6)-(1) in Fig. 3), condensed water is by being located at
The short tube of sector bottom is expelled directly out, and when state in (6) for being changed into Fig. 3, long tube has certain drainage.0 ° extremely
360 ° of overall processes, there are condensed water in all separating sectors all the time, but when sector is located above hollow shaft, condensed water is generated
Speed be much smaller than the velocity of discharge, water can be discharged in time.
Make condensed water under gravity by disc cavity bottom it should be noted that short tube is concordant with hollow shaft outer diameter
Portion is discharged into hollow shaft, and sustainable into vapour when not draining.Short tube is in whole cycle alternately into vapour and draining.Long tube is deep
Enter inside disc, when sector is at hollow shaft top, is still able to through long tube into steam.In entire rotation period, long tube
With short tube always more than hollow shaft liquid level.It is always ensured that at least one pipe into vapour, carries out phase-change heat-exchange, simultaneously because
It is alternately drained in long and short Guan Yi swing circle, can keep that too many condensed water will not be accumulated in lower half circle sector always, maintained
The phase-change heat-exchange of entire disc, to improve heat exchange efficiency.
Water delivery spiral welded is driven in water delivery screw outer cylinder by variable-frequency motor, with water delivery helical rotation, spiral outlet
Liquid level gradually rises, and can be processed by the setting of screw pitch, maintains full state so that exporting, and the condensation aqueous in hollow shaft
Position is then lower than the 1/3 or lower of internal diameter.Volume carries the water vapour into water delivery spiral can be by water delivery helical blade and outer tube inner wall
Between gap be back to hollow shaft, or can suitably increase hole on helical blade major diameter periphery, due to the table of condensed water
Face tension is much larger than water vapour, and water vapour will preferentially return to the top half of hollow shaft by hole.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model answers institute
It states and is subject to the protection scope in claims.
