Abstract
The invention discloses a vacuum rotary drying process which is applicable to drying granular powder materials under vacuum conditions and mixing the granular powder materials with one another. The vacuum rotary drying process includes feeding the materials; drying the materials, to be more specific, enabling steam to flow into a steam pipeline, heating a vacuum dryer, and draining cooling water out of a cold water pipeline; enabling a driving motor to drive a vacuum pump to rotate and pumping out air in the vacuum dryer; enabling waste gas in the vacuum dryer to flow into a condenser via a vacuum pipeline, condensing the waste gas, separating the gas from liquid, collecting the liquid into a solvent recycling tank and exhausting the gas; discharging materials, and to be more specific, discharging finished products from an opening after the materials are dried. The vacuum rotary drying process has the advantages that designs are reasonable, the vacuum rotary drying process can be used for drying the materials with low water contents, an internal structure is simple and smooth, is free of dead spaces, easy to clean and high in heat transfer coefficient, is short in drying time as compared with a tank type drying mode and is low in material abrasion as compared with a stirring drying mode, the high-quality products can be obtained by the aid of the vacuum rotary drying process, and the like.
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 when work are many, and internal structure is complicated, be difficult to cleaning, be 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 1, a kind of vacuum rotary drying process, has following steps:
A. charging, the material mouth of opening vacuum drier top packs material into;
B. dry, steam pipework passes into steam, and to vacuum drier heating, heating-up temperature is set as 60～130 ℃, 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 ℃, be set as-0.5MPa of vacuum.
Further, in described step c, be 60min drying time.
Further, described vacuum line is provided with the vacuum meter of monitoring vacuum drier internal pressure, and steam pipework is provided with Pressure gauge.
Further, described vacuum drier two ends are fixed in frame by swivel coupling.
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.For the dry material solvent that contains solvent or toxic gas, easily reclaim this function 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 that heat transfer coefficient is high, to compare drying time short with box-type drying, compare with agitating type material wearing and tearing less, can obtain the advantages such as quality product.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Wherein: 1. vacuum drier, 2. condenser, 3. vavuum pump, 4. vacuum line, 5. vacuum meter, 6. frame, 7. swivel coupling, 8. steam pipework, 9. cold water pipeline, 10. Pressure gauge, 11. drive motors, 12. material mouths, 13. solvent recovery tanks.
The specific embodiment
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, so it only shows the formation relevant with the present invention.
Vacuum rotary drying process as shown in Figure 1, has following steps:
A. charging, the material mouth 12 of opening vacuum drier 1 top packs material into;
B. dry, steam pipework 8 passes into steam, and to vacuum drier 1 heating, heating-up temperature is set as 120 ℃, and cooling water is discharged from cold water pipeline 9; Drive motors 11 drives vavuum pump 3 to rotate, and the interior air of vacuum drier 1 is extracted out, sets vacuum and is-0.5MPa; The interior waste gas of vacuum drier 1 enters condenser (2) condensation from vacuum line 4, gas-liquid separation, and liquid collection is to solvent recovery tank 13, and gas is discharged;
C. discharging, setting drying time is 60min, after dry end, finished product draws off from material mouthfuls 12.
Vacuum line 4 is provided with the vacuum meter 5 of monitoring vacuum drier 1 internal pressure, and steam pipework 8 is provided with Pressure gauge 10; Vacuum drier 1 two ends are fixed in frame 6 by swivel coupling 7.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
