Description
Technical field
The present invention relates to a kind of vacuum rotary drying device and drying process thereof of vacuum drying and mixing of applied powder granular material.
Background technology
In production equipment, the drying equipment appliance arrangement that is absolutely necessary.Traditional drying equipment comprises box drier and PADDLE DRYERS, and still, for the low temperature drying of heat sensitive material, the drying time of box-type drying is long, PADDLE DRYERS material wearing and tearing in the time of work are many, and internal structure complexity, is difficult to cleaning, is not easy to whole discharges of material.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of simple in structure, vacuum rotary drying device and drying process thereof that drying time is short, drying effect is good.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vacuum rotary drying device, comprise vacuum drier, on described vacuum drier, be connected with condenser and vavuum pump in turn by pipeline, the pipeline between condenser and vavuum pump is vacuum line; Described vacuum drier two ends are fixed in frame by swivel coupling, and described swivel coupling is provided with steam pipework and cold water pipeline, and vacuum drying machine drum body is hollow sandwich, and steam pipework and cold water pipeline are connected to interlayer; Described steam pipework is provided with Pressure gauge.
Further, described vavuum pump is provided with drive motors.
Further, described condenser is shell and tube condenser, and condenser bottom is connected with solvent recovery tank.
Further, described vacuum line is provided with the vacuum meter of monitoring vacuum drier internal pressure.
Further, described vacuum drier top is provided with the material mouth of handling material.
A kind of vacuum rotary drying process, has following steps:
A. charging, opens material mouth and packs material into;
B. dry, steam pipework passes into steam, and to vacuum drier heating, heating-up temperature is set as 60～130 DEG C, and cooling water is discharged from cold water pipeline; Drive motors drives vavuum pump to rotate, and air in vacuum drier is extracted out, and setting vacuum is-0.5～-0.1MPa; In vacuum drier, waste gas enters condenser condenses from vacuum line, gas-liquid separation, and liquid collection is to solvent recovery tank, and gas is discharged;
C. discharging, setting drying time is 45～65min, after dry end, finished product draws off from material mouthful.
Further, in described step b, heating-up temperature is set as 120 DEG C, be set as-0.5MPa of vacuum.
Further, in described step c, be 60min drying time.
The invention has the beneficial effects as follows: the present invention is reasonable in design, can be by dry materials to very low moisture content, therefore it is further dry to can be used for the material that moisture content is low.Easily reclaim this function for the dry material solvent that contains solvent or toxic gas and reach condition of high vacuum degree, its internal structure is simple, smooth without dead angle, and easily, material can all be got rid of in cleaning.In addition, also have heat transfer coefficient high, compared with box-type drying drying time short, compared with agitating type material wearing and tearing less, can obtain the advantages such as quality product.
