Specific implementation mode
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 be best understood from the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The range opened completely is communicated to those skilled in the art.
As shown in Figs. 1-2, disk desiccation machine according to the preferred embodiment of the present invention includes：It is desiccation machine shell, hollow
Axis 1, disc, sludge inlet 11, sludge outlet 12, steam inlet 13 and water delivery spiral 8.Wherein, hollow shaft 1 runs through desiccation 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 located at desiccation machine
In shell.Sludge inlet 11 is opened in desiccation machine shell upper, and sludge outlet 12 is opened in desiccation machine outer casing underpart.Steam inlet
13 are set to desiccation machine shell side.Water delivery spiral 8 is set to the other side of the desiccation machine shell opposite with steam inlet 13.
In said program, disc 2 is formed by two panels disk butt welding, and the inside of disc 2 has a cavity, cavity be partitioned every
Plate 5 is divided into a plurality of cavities region.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 board 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 board 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 to from the gap of water delivery spiral 8 and water delivery screw outer cylinder 9 in hollow shaft 1.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
It is back to steam inlet 13 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 operation principle of the present invention is introduced referring to Fig. 3.
Fig. 3's（1）In, 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 also can 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 in Fig. 3（1）-（2）-（3）-（4））, this point
Partition board area continues into water vapour, and reservoir storage gradually increases, when positioned at Fig. 3's（4）When position, disc inner product water reaches most
Greatly, then start to drain；By 180 ° -360 °（In order referring in Fig. 3（4）-（5）-（6）-（1））, condensed water is by being located at
The short tube of sector bottom is expelled directly out, until being changed into Fig. 3's（6）In state when, 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 generates
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 on 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 a pipe carries out phase-change heat-exchange into vapour, 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 so that and it exports and maintains full state, and the condensation aqueous in hollow shaft
Position is then less 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 foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention answers the protection model with claim
Subject to enclosing.
