Device has three state:
1. air circulation dehumidified state；
2. silica gel heating drying regime；
3. standby mode.
Device realizes sealing by multiple solenoid valves, prevents outside moisture from entering silica gel case.
Air circulation dehumidified state (schematic illustration is as schemed): three solenoid valves two and solenoid valve one are opened, while three
Air exhauster is opened, and solenoid valve three and heating air exhauster are closed, and system is in circulating dehumidification state at this time.Pass through blower exhausting
Equipment to be dehumidified is re-fed into after forcing the air over silica dehydrator；In addition, three solenoid valves two of air valve and solenoid valve one are connected to control
It is opened after system order, is then delayed after 5S, is then turned on three air exhausters, since solenoid valve unlatching needs certain time, sometimes
Prolong, open air-valve while if opening blower, is easily damaged air-valve, therefore need to be then turned on wind by delay after air-valve unlatching
Machine.Air inlet of the air through airstrainer → solenoid valve one → silica gel particle layer → two → air exhauster of solenoid valve → arrives at this time
In cabinet to be dehumidified, complete to be air-dried in equipment to be dehumidified.
Silica gel heating drying regime: when four humidity sensors, any one detects that humidity is greater than the set value, pass through
Controller controls three air exhausters and closes, while three solenoid valves two are closed；While solenoid valve three is opened, opened after the 5S that is delayed
Heating air exhauster is opened, and at the same time opening eight groups of heaters (using electrothermal tube), heating air exhauster enters silica gel and adds at this time
Heated drying state.At this time silica gel case outside air through one → silica gel of solenoid valve (heated condition) → exhaust pipe → solenoid valve three → plus
Outside thermal exhaust blower → discharge silica gel cabinet, that is, by blower forced circulation while heating, takes away after silica gel is heated and shed
Steam, it is dry to complete silica gel heating.
Standby mode: when device to be dehumidified is without dehumidifying, and silica gel case humidity is not up to setting value, device was both not at
Circulating dehumidification state, not also in heat drying state, three air exhausters and heating air exhauster are turned off, then device at this time
