The impeller assembly 4 supported by central axis 3,3 one end of central axis connect transmission mechanism 1 by shaft coupling, and transmission mechanism 1 is by electricity
Machine, belt and speed reducer are constituted, and 2 outer surface of shell is provided with collet 21, and the first steam inlet 23 and the are offered on collet 21
One condensation-water drain 24, in order to which regulating effect can be improved, in 2 outer surface of shell according to outlet moisture percentage in sewage sludge adjusted stepwise
Provided with three mutually independent collets 21, it is provided with dome 22 at the top of shell 2, exhaust outlet 25, sludge are offered on dome 22
The vapor that moisture is formed is gathered in dome, is taken out of by the pumping exhaust mouth 25 of exhaust fan, and 4 inside of impeller assembly is in
Hollow and internal interconnected inside mandrel 3,3 other end of central axis is provided with the second steam inlet 81 by rotary joint 8
With the second condensation-water drain 82.
Distribution pipe 42 corresponding with the impeller disk piece quantity of impeller assembly 3 is provided in central axis 2, each distribution pipe 42 is right
An impeller disc is answered, 42 bosom of distribution pipe is provided with partition 43, offers on 42 side wall of distribution pipe of 43 side of partition
Third steam inlet 44 offers third condensation-water drain 45 on 42 side wall of distribution pipe of 43 other side of partition, and third steam enters
Mouth 44 is connected to the 4th steam inlet 46 of impeller discs, and third condensation-water drain 45 is connected to the 4th condensation-water drain of impeller disc
47；Condensation water collection bucket is provided at 4th condensation-water drain 47, condensation water collection bucket is by impeller disc inner wall and two block baffles
41 surround, and one piece of long baffle is connect with impeller disc inner wall and 3 outer wall of central axis, another piece short baffle one end and central axis
The connection of 3 outer walls, the other end are not connect with impeller disc inner wall, so that there is an import at this.
Scraper plate 5 is provided between two adjacent impeller discs, scraper plate 5 is fixed on 2 inner wall of shell, due to dryer inner
Sludge is the very high wet mud of moisture content, to prevent sludge to be bonded on impeller assembly 3, by the way that scraper plate 5 is arranged, reaches the impeller disk
Gap between piece plays the role of stirring sludge, cleaning disk.
It being almost arranged in a mutually vertical manner between impeller disk and central axis 3, the rotation of itself has no effect on the flow direction of sludge, and
And impeller disk revolving speed is 4-8r/min, wears very little；Impeller disk piece end outer is provided with paddle 6, paddle 6 and sludge
Arrangement at an acute angle between conveying direction tilts towards the sludge direction of motion, had not only helped sludge to make directed flow, but also play stirring
The effect of sludge.
First steam inlet 23 and the second steam inlet 81 are passed through low-pressure steam, so that the sludge on impeller assembly 4 is stopping
It will not be overheated when vehicle, safety is good.
