Be configured in the feed end place of cylinder, structure be disposed to supply wet stock or liquid material is interior with the conveying device making it evaporate to steam dryer.
Background technology
In the prior art, the known dissimilar multiple drying drum by utilizing based on steam, except other type, uses cylinder to be used for dry different wet stock.In the steam dryer of described type, dry material to be introduced in drying, and be intended to flow being installed in the pipe in cylinder for dry steam.Therefore, dry material directly not contact steam.Drying drum is divided into two kinds of main types, that is, batch-type drier, and on the other hand, continuous dryer.In batch-type drier, wherein, as an example, the drier described by Deutsche Bundespatent No.2724639 can be mentioned, drying drum is filled into required inventory, starts to supply steam to the Guan Zuzhong be placed in drying drum, and drying drum starts to rotate simultaneously.After the abundant drying of material wanting drying, stop cylinder rotating, turn off steam supply, empties cylinder.Therefore, a shortcoming of batch-type drier, just because of its method of operation, drier can not be used for dry a large amount of material reposefully.
In continuous dryer, arrange and usually make drying drum rotate continuously, and want dry material to be fed to drums inside through cylinder one end.Between dry period, steam continues to enter the pipe-line system being placed in drums inside.Cylinder has ad hoc device, by this device, cylinder is during drying rotated, and further, make during drying to put into the wet stock in cylinder and move towards the opposite end of cylinder, material is discharged from this end.Usually, cylinder has adjustable spilling weir or has adjustable discharge port, and further, the position of usual drum-inclined can adjust within the specific limits, to regulate in cylinder by the time of staying of mummification material.Can mention that the steam dryer described by WO98/02700 can be used as an example of this continuous drying cylinder.
The structure of prior art intermediate roll formula steam dryer as above, the use of this drier illustrated by way of example is quite general, and in such drier, the axis that steam pipe is arranged essentially parallel to cylinder is installed.In this arrangement, sometimes, the problem found is that dried material forms the thermal insulation layer of material on the surface at steam pipe.In the drier of this prior art using longitudinal pipe, the packing density in machine is relatively low, that is, the degree of the 10%-15% of drums inside capacity, and this cylinder is not generally used for drier mineral materials because drier size large and efficiency is low.
Further to be it define heating surface with an independent rotor and have the static holddown groove of horizontal positioned at peritrochanteric the drying device of prior art.Usual rotor is made up of many parallel tube banks, and they are arranged along center conduit, and each tube bank generally includes many concentric pipe rings, and the heat transfer medium used can be steam or liquid.In the scheme of this prior art, what end installed that bearing and steam pipe system will rotate in dried wet stock limits its size, and especially when the amount of wet stock increases, the size of equipment can not increase economically.The sizable shortcoming of this kind of drier is that steam pipe consumes rapidly, this causes very large problem when drying and grinding mineral, because rotor rotates in static material bed, to be applied to the pressure of steam pipe high and cause more serious wearing and tearing as above for concentrate in this case.
Further the dryer configuration of prior art describes in U.S. Patent No. 6415527.Describing in this patent is especially Concentrate Drying and the steam dryer that designs, and wherein drier wearing and tearing reduce to some extent relative to prior art described above, and thus wearing and tearing can not cause similar problem.In the dryer drum of US6415527, the pipe group being placed in cylinder is made up of multiple elements, and this pipe group can remove from cylinder separately and replace.So the service life of drier and availability fairly good because duct element can be replaced quickly and easily if desired, which reduce the downtime of drier.Steam pipe group in the drier of this prior art is rotated together with cylinder, in this case, only have between dried material and steam pipe low material pressure and the little rate of wear poor, the problem that the wearing and tearing of steam pipe produce than aforementioned drier is few.But, still have some problems to exist, and therefore still need to improve this kind of drier.
Even if the structure of US6415527 patent is developed, drying efficiency and the packing density of the cylinder at that time this United States Patent (USP) are considered to suitable satisfaction, but have nowadays proposed to produce more high efficiency requirement.The cylinder of US6415527 steam dryer has uniform cylindrical chamber.Now, in such cylinder, when wanting dry wet stock to be fed in cylinder, it falls the bottom of cylinder, so that only have sub-fraction steam pipe to contact with described wet stock.Therefore the heating surface (area) (HS of steam pipe is not effectively utilised as right.Another problem about US6415527 cylinder comes from the combining structure of steam distribution concetrated pipe and discharge end room.In US6415527 cylinder, described steam pipe distributes concetrated pipe and radial tube connector, flexible hose etc. and is all positioned at described discharge end indoor.There, in the environment that they are exposed to containing airborne dust, humidity and corrosive gas.
