Vacuum drying system as shown in Figure 1 and Figure 2 includes vacuum pump 17, and vacuum pump 17 uses water-ring vacuum pump, vacuum
Pump 17 is connected by vacuum pipe with cabinet 13, the list that vacuum solenoid 19 is equipped on vacuum pipe and prevents cooling water from flowing back
To check-valves 18, the pressure release electromagnetic valve 20 for venting drying chamber pressure is installed on cabinet 13, is equipped with below cabinet 13
The manual ball valve 21 of draining is being equipped with sealing ring 11 and pressure knob close to 9 side of chamber door, to guarantee drying box operating room
Air-tightness.Drying box chamber door 9 is unilateral enabling, and the vacuum meter 8 and observation object of measurement drying chamber vacuum degree are provided on chamber door
Expect the observation window 10 of drying regime.It is placed with material frame 14 inside cabinet 13, is fixed on material frame 14 and gives material heat supply
Electric boiling plate 15, be placed with material disc 16 on electric boiling plate 15.
As shown in Figure 1 and Figure 2, air inlet solenoid valve 1, tonifying Qi solenoid valve 2, warm and humid wherein the hot wind auxiliary heater 4
It is electric with controller to spend sensor 3, centrifugal blower 5, wet-emitting blower 6, vacuum pump 17, vacuum solenoid 19, pressure release electromagnetic valve 20
It is connected, controller can control the open and close of each valve, blower, hot wind auxiliary heater 4, vacuum pump 17.
As shown in Figure 3: electric boiling plate 15 is cast aluminium electric boiling plate, is fixed on material frame 14 by being implanted into 4 screws,
There are temperature sensor fixing hole and two insulator binding posts, the temperature sensor fixing hole among 15 side of electric boiling plate
On temperature sensor has been installed, wherein two insulator binding posts and temperature sensor pass through high temperature resistant line and intelligent temperature control
Instrument is connected.
As shown in Figure 4: 16 bottom plate of material disc is made using rectangular metal space aluminum, and bottom plate surrounding is provided with 10 mesh 304 not
Steel sieve become rusty so that hot wind is uniformly through material disc 16.
Working principle of the utility model is:
The material to be dried is put into material disc 16 first, the material disc 16 equipped with material is then put into drying box material
On frame 14, chamber door 9 is closed, and locked with pressure knob.
The heated-air drying stage: opening air inlet solenoid valve 1, and return air solenoid valve 7 opens centrifugal blower 5, sets hot blast temperature,
Hot wind auxiliary heater 4 is opened, at this point, hot wind enters gas distribution chamber 12 by air inlet solenoid valve 1, enters the right side across drying chamber
Sidewind distributor chamber starts hot air circulation drying into hot air circulating pipe through return air solenoid valve 7, when Temperature Humidity Sensor 3 is felt
Should arrive drying box hot wind humidity it is too big when, open tonifying Qi solenoid valve 2, open wet-emitting blower 6, the too big hot wind of humidity is discharged,
It is then turned off tonifying Qi solenoid valve 2, wet-emitting blower 6, then proceedes to start hot air circulation drying, the closing of hot-air drying process approximation follows
Ring is dry, when only hot wind humidity is excessive, just opens hydrofuge, i.e., intermittent hydrofuge reduces energy consumption.It simultaneously can in heated-air drying
To open the auxiliary heating of electric boiling plate 15, drying efficiency is improved.
Drying phase under vacuum: when starting vacuum drying, air inlet solenoid valve 1, return air solenoid valve 7, pressure release electromagnetic valve are closed
20, vacuum solenoid 19 is opened in manual ball valve 21, and vacuum degree is arranged, and opens vacuum pump 17, then vacuum pump is by 13 drying chamber of cabinet
Room is evacuated to setting vacuum degree, is then turned off vacuum solenoid 19, turns off vacuum pump 17, sets vacuum drying temperature, opens temperature
Control instrument control electric boiling plate 15 heats material, and under negative pressure state, water boiling point is lower, thus accelerate moisture evaporation, it is real
Now it is dried in vacuo.According to different material humidity degree, drying time is different, and if drying time is longer, vacuum degree decline is needed again
Pumping restores vacuum degree and is then turned on vacuum solenoid 19 at this point, vacuum pump 17 should be opened first.When completing vacuum drying, open
Pressure release electromagnetic valve 20 lets out 13 drying chamber of cabinet to normal pressure, then opens chamber door and take out material.
