Negative pressure of vacuum table (35) and refrigerator pipes (34) and liquid crystal temperature control display instrument (36) are housed on drain sump (25) outer wall.

The schematic diagram of Fig. 1 microwave sublimating dewatering device.

Now in conjunction with the accompanying drawings the structure of vacuum condensation unit microwave sublimating dewatering device is described in detail:

By Fig. 1, lobe pump (3) and mechanical pump (4) are housed in the vacuum unit frame (1), a lobe pump (2) is also adorned on frame (1) top, lobe pump (2) (3) and mechanical pump (3) be serial connection mutually, form a vacuum unit, electromagnetism pressure reduction venting vaccum stop valve (5) joins with flange and lobe pump (2), again with flange bridge piece (6) and horizontal vacuum pipe (7), again successively with high vacuum butterfly valve (8) bend pipe (9), after joining, vertical vacuum tube (10) is connected to condenser (11) above the right-hand member, condenser (11) left end also connects vertical vacuum tube (19) and bend pipe (20) with flange, connect horizontal vacuum pipe (21) high vacuum butterfly valve (22) and bend pipe (23) successively again, threeway vacuum tube (24), the two ends of threeway vacuum tube (24) are connected to again above the microwave distillation drain sump (25), microwave distillation drain sump (25) is that a horizontal direction is arranged, and long cylinder, respectively there is the end cap (30) and the end cap crane (33) of automatic open close at two ends, the left and right sides, locate all to have a microwave waveguide device (29) at two ends near end cap (30), be used for joining with microwave generator, microwave dehydration jar (25) outer wall installs temperature control evaporimeter (27) additional, its skin is heat-insulation layer (28), heat-insulation layer adds stainless sheet steel, outer decorate (32), establish the stainless steel square chamber in jar, all there is defeated material guide rail (figure slightly) both sides in the square chamber.

On the outer wall of microwave distillation drain sump (25) bottom support (31) is housed, negative pressure of vacuum table (35) and refrigerator pipes (34) are housed on the external wall of upper portion, liquid crystal temperature control display instrument (36), condenser (11) also is long cylinder, outer wall is heat-insulation layer (13), its skin is the outer decoration (14) of stainless sheet steel system, inner chamber has a refrigerating evaporator (12), one end end cap band loose-leaf, other end end welds, and the operating pressure of condenser (11) is-0.01-0.2Kpa that operating temperature is below-60 ℃, support (15) is equipped with in condenser (11) bottom, and two coolant tubes (16) and negative pressure of vacuum table (17) and liquid crystal temperature display instrument (18) are equipped with in top.
