To achieve these goals, the scheme of the utility model employing is as follows:
Multistage combined drying device, comprise master control oven dry cylinder, dry cylinder by the master control moisture trap with the secondary that master control oven dry cylinder is connected, dry three grades of oven dry cylinders that cylinder is connected by secondary moisture trap and this secondary, this drying equipment also is provided with one by three grades of moisture traps and described three grades of jugs that the oven dry cylinder is connected, and described master control oven dry cylinder group is comprised of two master control oven dry cylinders that are in parallel, and between secondary moisture trap and three grades of moisture traps, be provided with three condensate pumps that are communicated with it by pipeline, and described condensate pump all is communicated with jug by conduit, and in master control oven dry cylinder group, be equipped with temperature sensor in secondary oven dry cylinder and three grades of oven dry cylinders, this temperature sensor is connected with outside central controlling chamber, top at described three grades of moisture traps also is provided with the steam accumulator that is communicated with it by conduit, this steam accumulator is communicated with master control oven dry cylinder by conduit equally, and it is circumscribed with one in order to the heating facility of heating steam.
Further, on described three grades of moisture traps, also be provided with a conduit that is communicated with it, and the external vavuum pump of an end of this conduit.
Further, described jug is uncovered shape.
Further, also be provided with the condensate pump that is communicated with it in described jug bottom.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and with low cost, realization convenience;
(2) the utility model and be provided with three condensate pumps that are communicated with it by pipeline between secondary moisture trap and the three grades of moisture traps, and described condensate pump all is communicated with jug by conduit.Condensate pump can be cooled to rapidly liquid state with steam, again in the jug by the pipeline inflow, has effectively avoided being difficult to steam and has been difficult to condense and is retained in the pipeline of drying equipment, affects the defective of drying efficiency;
(3) master control oven dry cylinder group is made of two equal master control oven dry cylinders in the utility model, it is reduced to the two-stage oven dry with traditional multistage oven dry, when guaranteeing drying effect, has reduced widely the shared area of oven dry cylinder, not only simplify operation, and reduced production cost;
(4) the utility model also is provided with a jug that is connected with three grades of oven dry cylinders by three grades of moisture traps, jug is in order to receive condensed steam, by the condensate pump that is arranged on its bottom it is cooled off again, steam after being cooled can be recycled again, saving water resource.
