The invention belongs to the technical field of microwave drying, particularly relates to a device for microwave drying germanium dioxide. The invention improves a household microwave oven which is used as the main body; the top plate of the microwave oven is changed into a metal mesh structure, and an exhaust fan is arranged at the top of the microwave oven; a temperature control system is arranged in the microwave oven; a high-temperature automatic alarm system is arranged on the circuit connected with a transformer; the rotating shaft of a rotating disk is composed of a plurality of blades;and both cover plates of internal and external baffles of the microwave oven are coated with nanometer protective paints. When the device is used for drying germanium dioxide, the overall drying timeis short, the water content of the dried germanium dioxide achieves the national standard, and the crystalline form of the germanium dioxide does not change. The invention has the advantage of low energy consumption, avoids high environment temperature, reduces working labor intensity and can be used in other dehydration and drying fields for reference.
Description
Technical field
The invention belongs to technical field of microwave drying, particularly a kind of equipment of microwave drying germanium dioxide.
Background technology
Germanium dioxide is a kind of germanium compound that important use is arranged in fields such as chemical metallurgy, generally gets by the high-purity germanium tetrachloride preparation of hydrolysis.But because hydrolysis GeCl
4Prepared GeO
2Still certain water and crystal water can be contained through behind the centrifuge dripping, therefore these water and crystal water must be removed earlier.Traditions of the past process using baking oven is dried it, but has the energy consumption height with baking oven, and baking cycle is long, and GeO
2Easy shortcoming such as caking in bake process.Therefore our company adopts the method for microwave drying to dry now, microwave drying is under the high frequency electromagnetic field effect, the material absorption of electromagnetic energy, the impellent that is converted into the heat mass transfer in material inside is the inner pressure gradient that produces rapidly of material, liquid can pressure gradient effect under from material, discharge rapidly.Therefore, contrast traditional drying means, microwave drying has that rate of heating is fast, homogeneous heating, effectively utilize advantage such as energy.But it is excessive to buy the special-purpose fund that microwave oven spent, and, industrial microwave oven and household microwave oven on some key element (as magnetron) model substantially, consider the production problems of the germanium dioxide of maintenance issues and our company, can use household microwave oven to realize drying effect.
Household microwave oven microwave output power 700w, the microwave transmitting frequency is 2450MHZ, comprise equipment such as magnetron, waveguide mouth, the time relay, rotating disk, consider the inventory of every batch of germanium dioxide, adopt household microwave oven can finish the microwave drying task of germanium dioxide substantially.But have the following disadvantages when being to use household microwave oven: the inner no exhaust fan of cavity of household microwave oven is unfavorable for the water vapour evaporation; Anhydrous minute means of detection of domestic microwave furnace interior, can't know whether inner germanium dioxide dries, and when the germanium dioxide internal moisture was dried, dry material-germanium dioxide became main energy absorption person, under the effect of frequency electromagnetic waves, make germanium dioxide produce other chemical transformation easily; Supply transformer can burn transformer easily because of self power consumption heating when household microwave oven used for a long time; The household microwave oven supporting capacity is limited, and the rotating shaft position of rotating disk is fragile; When producing germanium dioxide, because the hydrolysis germanium tetrachloride can produce hydrochloric acid, so household microwave oven easily is corroded when using in the production scene.
Summary of the invention
The present invention is directed to the deficiency of household microwave oven when dry germanium dioxide, a kind of equipment of microwave drying germanium dioxide is provided,, has made the top board 5 of microwave oven 1 into wire netting poroid structure based on microwave oven 1, play the effect of electromagnetic shielding, avoid microwave leakage; And the vent fan system 2 of taking out is set at the top of microwave oven 1, to improve the volatilization of water vapour; Temperature control system 3 is installed in microwave oven 1; On the circuit that connects transformer, the high temperature automatic alarm system is set; The rotating shaft 7 of rotating disk 6 is made of 4～10 flabellums.
The metal mesh opening of described top board 5 adopts copper mesh as shielding material, and thickness is 0.5～3mm, and mesh diameter is 1.5～4.5mm.
Described temperature control system 3 adopts long-range inductive probe that the microwave oven internal temperature is surveyed.
All scribble the nanometer protective paint on the cover plate of the interior outer baffle of described microwave oven 1 and the blower fan, play erosion-resisting effect.
Beneficial effect of the present invention is: adopt equipment of the present invention that germanium dioxide is carried out drying, overall drying time is about 2 hours, shortened drying time, and oven dry back germanium dioxide water content is up to state standards discovery germanium dioxide crystalline form no change behind the process electron-microscope scanning; Can cut down the consumption of energy behind the equipment after the improvement, avoid high ambient temperature, reduce labor intensity, and can use for reference other dewatered drying field.

Embodiment
The invention provides a kind of equipment of microwave drying germanium dioxide, the invention will be further described below in conjunction with description of drawings and embodiment:
Fig. 1 is a microwave oven synoptic diagram of the present invention; Fig. 2 is a microwave oven schematic perspective view of the present invention.Use household microwave oven, and make improvements:
(1) Fig. 3 is the vertical view of microwave oven cavity upper plate wire netting; Make the top board 5 of microwave oven 1 into wire netting poroid structure, adopt copper mesh as shielding material, thickness is 1mm, and the aperture is 3mm, and the poroid structure of wire netting can play the effect of electromagnetic shielding, avoid microwave leakage, the vent fan system of taking out is installed at microwave oven 1 top,, takes out the FZ560B0000 type interchange aerofoil fan that vent fan system 2 adopts FANS-TECH company to produce to improve the volatilization of water vapour, power 420W, rotating speed 880RPM;
(2) add temperature control system 3 in microwave oven 1, temperature control system 3 adopts the Luxtron Luxtron FOTLab Kit of company type optical fiber temperature-measurement meters as temperature measuring equipment (adopt the long-range inductive probe of STR type, range-25～330 ℃); Temp controlled meter adopts the Japanese SHIMAX MAC50A of company type temperature control instrument; When washiness, microwave energy is mainly absorbed by water, temperature can remain on a general constant temp in the stove, when moisture in the few or material substantially anhydrous the time, dry material-germanium dioxide becomes main energy absorption person, and this is that temperature will raise, when temperature is elevated to a certain degree, can make microwave oven 1 stop heating automatically by temperature control system 3;
