Specific embodiment
The present invention is specifically described with reference to the accompanying drawing, as shown in figures 1 to 6, in the present embodiment:
It in the present apparatus, is powered by the way that device to be connect with external power supply, by control mechanism 2 and extraction fan 5, miniature
Electric telescopic rod 16, spiral electric heating wire 23 and air humidity sensor 29 are attached, so that control device is run；
It is divided into drying regime mode and desiccant drying mode in the present apparatus:
When desiccant is in drying regime mode, at this time when external air currents, air passes through the circle on round thermovent 3
Shape dust cover 4 carries out preliminary dedusting, enters back into drying box 6, passes through the montmorillonite desiccant bag in two fixed network boards 7
8 be interspersed, so that the gap bypassed air through between montmorillonite desiccant bag 8 is passed through into drying box 6, passes through in air
During drying box 6, the moisture in air by being in contact with montmorillonite desiccant bag 8, thus by the moisture in air into
Row absorbs, and then dry air is entered in electric power cabinet ontology 1 by the gap between the blade 11 in shutter frame 10
Portion enters the other side to pass through the gap between the blade 11 in the shutter frame 10 on the drying box 6 of the other side
In drying box 6, then by the round thermovent 3 of the other side air is discharged, to carry out the heat dissipation inside electric power cabinet ontology 1；
Montmorillonite desiccant bag 8 absorbs the moisture in air, when montmorillonite desiccant bag 8 is inhaled by contacting for a long time with air
After the moisture of receipts is at saturation state, the moisture in air is initially entered in electric power cabinet ontology 1, passes through air humidity sensor 29
Detect the air humidity in electric power cabinet ontology 1, when the air humidity inside electric power cabinet ontology 1 reaches setting value, device at this time
Enter desiccant drying mode；
When device enters desiccant drying mode, control miniature electric telescopic rod 16 first starts to stretch out, and miniature electric is stretched
Contracting bar 16 adjusts rope 15 and is started by the effect of extension spring 14 by stretching out to make to adjust rope 15 in relaxed state
It moves up, with moving up for rope 15 is adjusted, makes 11 1 side contacts of blade, so that shutter frame 10 is blocked,
It is sealed by waterproof sealing gasket 13, so that it is minimum to guarantee that the gas permeability of shutter frame 10 is reduced to；
First control spiral electric heating wire 23 is begun to warm up at this time, while the extraction fan 5 for controlling side is started to work, extraction fan
5 by the connections of drying square tube 17, two perpendicular drying pipes 18 and dehumidification pipe 19, to start to 1 inside of electric power cabinet ontology and another
The round thermovent 3 of side is evacuated, and air is entered in drying square tube 17 by perpendicular drying pipe 18 and dehumidification pipe 19, is passed through
Spiral electric heating wire 23 heats, and increases the temperature of air, while the moisture in air being evaporated, and the moisture of evaporation is with air
Flow into the drying box 6 of side, montmorillonite desiccant bag 8 is persistently blowed to by high temperature air, thus de- by covering
Moisture in stone desiccant bag 8 is evaporated, as the flowing of air is discharged from extraction fan 5；
When the extraction fan 5 of side works after a certain period of time, the extraction fan 5 for controlling the other side at this time works, to pass through phase
Same structure dries the montmorillonite desiccant bag 8 in the drying box 6 of the other side, controls the contraction of miniature electric telescopic rod again at this time
Blade 11 is opened the dehumidifying that can be carried out again in electric power cabinet ontology 1 by 16；
In the present apparatus, square tube 17 is dried by being arranged to big V-type, and the moisture in air can effectively be facilitated to evaporate heel row
Out, it prevents inside residual moisture to device；Spiral electric heating wire can effectively be guaranteed by thermal insulation material and cooling fin simultaneously
When 23 heating, 26 upper surface of quad seal baffle will not generate any condensation, to guarantee dry inside electric power cabinet ontology 1
It is dry；And conical shrinking plate 20 and taper cover plate 22 are set in dehumidification pipe 19, vapor can be effectively reduced along removing
Wet pipe 19 rises and flows back into inside electric power cabinet ontology 1.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
