Embodiment 2:
Figure slightly, only changes the quantity of one group of peripheral concentrated cylinder 3 into six, and the quantity of corresponding the first knifing mechanism 4 is also six; Change the quantity of the concentrated cylinder 5 in center into one, the quantity of corresponding the second knifing mechanism 6 is also one.All the other are all with the description to embodiment 1.
The applicant is in conjunction with Fig. 1 and Fig. 2 and describe the course of work of the present invention according to the explanation of embodiment 1.The high-temperature steam produced as boiler by vapour source is introduced interface 15a from steam by the road and is incorporated in the steam heating cavity 112 in tank chamber 11, simultaneously, awaits concentrated material by the road in charging interface 14a introduces distribution cavity 111.Because a concentrated chamber 31, the periphery of one group of peripheral concentrated cylinder 3 communicates with distribution cavity 111 by the first blowdown slotted eye 32, therefore the material in distribution cavity 111 enters peripheral concentrated cylinder chamber 31 from the first blowdown slotted eye 32, and the inwall trickling in concentrated cylinder chamber 31 along periphery, simultaneously, because a concentrated chamber 51, the center of the concentrated cylinder 5 in center communicates with distribution cavity 111 by the second blowdown slotted eye 52, therefore the material in distribution cavity 111 enters concentrated cylinder chamber 51, center from the second blowdown slotted eye 52, and concentrates the inwall trickling in cylinder chamber 51 along center.Now, under the work of power drive mechanism 2, by motor 21, drive reduction box 22, by reduction box 22, slowed down, and drive main shafts 23 through reduction gearbox output shaft 221, because gear wheel 26 and pinion 27 all are fixed on main shaft 23, therefore by main shaft 23, drive large and small gear 26,27 motions simultaneously.Because gear wheel 26 is meshed with the first scraper shaft gear 44 of the first knifing mechanism 4, because pinion 27 is meshed with the second scraper shaft gear 64 of the second knifing mechanism 6, therefore by large and small gear 26,27, drive respectively first, second scraper shaft gear 44,64 rotations again.And then drive the first scraper shaft 42 rotations by the first scraper shaft gear 44, and drive the second scraper shaft 62 rotations by the second scraper shaft gear 64.Drive the first scraper plate 43 again and then by the first scraper shaft 42, by the first scraper plate 43, by the concentrate on the wall of concentrated cylinder 31 chamber, chamber, periphery, be that liquid film scrapes, drive the second scraper plate 63 by the second scraper shaft 62, be that liquid film scrapes by the concentrate on the wall of concentrated cylinder 51 chamber, chamber, the second scraper plate 63Jiang center simultaneously.The concentrate scraped enters 113(discharging chamber, discharging chamber and also can be described as storage cavity) in, finally by concentrate fairlead 16, drawn, open the baiting valve 161 be provided on concentrate fairlead 16 while drawing, otherwise close baiting valve 161.In said process, the self cooling lime set outlet of the condensate liquid be transformed by steam-condensation 15b in steam heating cavity 112 draws, and the boil-off gas (steaming residual air) of in material, steaming all solvents and so on as the aforementioned that remove in evaporation process enters distribution cavity 111 by first, second evaporation fairlead 412,612 respectively, and draw interface 14b by indirect steam and draw.
In sum, technical scheme provided by the invention has made up the shortcoming in the prior art objectively, has successfully completed the invention task, has cashed strictly according to the facts the technique effect described in the superincumbent technique effect of the applicant hurdle.
