In the present invention, implement, the compressor 1 is preferably the compressor of frequency conversion type.
In the present invention, it should be noted that the compressor 1 is used for absorbing the low-temperature low-pressure refrigerant in evaporimeter 4
Steam, and after compressing it into the overheated gas of HTHP, it is drained into condenser 2；
The condenser 2, is mainly used in providing the heat exchange place of high temperature refrigerant and circulation air, in condenser 2
Cold-producing medium is by the heat transfer of itself to outside circulation air, and causes the temperature drop of itself and condense, and circulation air
Temperature raise and relative humidity decline；
The choke valve 3, it is low pressure two-phase fluid to be mainly used in the high-pressure refrigerant expansion throttling of liquid；
The evaporimeter 4, in which, the liquid refrigerant of low-temp low-pressure is realized by absorbing the heat of outer loop air
Evaporation, then in compressor 1, and after the circulation air of outside rejects heat to the cold-producing medium in evaporimeter 4, circulation
The temperature drop of air and precipitation moisture.
For the present invention, in order to more understand that ground understands technical scheme, the work to the present invention is former below
Reason is illustrated.
When running for the first time, the first material inlet valve 9 and the second material inlet valve 11 is opened, material to be dried is passed through feed hopper
10 send in the second conveyer 12 in drying box 8.Second conveyer 12 is run, and material to be dried is passed through first
Air deflector 13 is imported in second conveyer 14.At this time, by adjusting charging rate and second conveyer 12 and second
The running speed of conveyer 14, can adjust spreading depth of the material on conveyer.When material to be dried is first
After being evenly distributed on conveyer 12 and second conveyer 14, stop charging, and close second conveyer 12 and second passing
Send device 14.Then, the first material inlet valve 9 is closed, it is closed mode to keep the second discharge valve 18, opens vavuum pump 22, beats
The first discharging opening 16, the first vacuum valve 20 and the second vacuum valve 21 is driven, the air in drying box 8 is discharged so that in drying box 8
In vacuum state；Then, the second material inlet valve 11, the first discharge valve 16, vavuum pump 22, the first vacuum valve 20 and the are closed
Two vacuum valves 21.Start compressor 1, after the refrigerant heat in compressor 1, formed HTHP cold-producing medium be delivered to cold
In condenser 2, and heat exchange is carried out with the outer loop air flowed through at the condenser 2 in condenser 2 so that cold-producing medium becomes
Become liquid, subsequently, the cold-producing medium of liquid carries out throttling cooling at choke valve 3, continues through refrigerant tubing 5 and flow to evaporimeter
In 4, the cold-producing medium of low temperature liquid will evaporate and absorb the heat of the air for flowing through this in the evaporimeter 4, so as to complete refrigeration
Agent is circulated, that is, realize recycle stream of the cold-producing medium in compressor 1, condenser 2, choke valve 3, evaporimeter 4 and refrigerant tubing 5
Dynamic.
It should be noted that cold-producing medium is occurred mainly at condenser 2 and evaporimeter 4 with the heat exchange of circulation air,
At condenser 2, the heat that circulation air is discharged when condensing the cold-producing medium in absorptive condenser 2, pass through after temperature is raised
Air channel 7 enters in drying box 8, for drying material to be dried, subsequently, circulation air after evaporimeter 4 is flowed through, and by heat
The cold-producing medium of the low temperature liquid in evaporimeter 4 is passed to, the temperature drop of circulation air, while the moisture inside circulation air
Condense and separate out.
After the completion of first dry materials, in order to material is changed, need the first discharging opening 16 is opened, start first and transmit
Device 12 and second conveyer 14, the material for having dry are concentrated in discharging by the first air deflector 13 and the second air deflector 15
Bucket 17, is then shut off the first discharging opening 16, opens the second discharging opening 18 and take out material, can avoid outside air entrance again dry
In dry case 8, after taking out the material for drying, the second discharging opening 18 is closed.At the same time, first charging aperture 9 is opened by next group
Material to be dried add feed hopper 10, be then shut off first charging aperture 9.Vavuum pump 22 is opened, opens 20 He of the first vacuum valve
Second vacuum valve 21, the air in feed hopper 10 and discharge bucket 17 is discharged, and is maintained and the vacuum state in drying box 8, it is to avoid
The oxygen that in the air has in feed hopper 10 and discharge bucket 17 flows into and drying box 8 is had undesirable effect.Open the second charging
Mouth 11, material are sent in the second conveyer 12 in drying box 8.Second conveyer 12 is run, and material to be dried is led to
Cross the first air deflector 13 to import in second conveyer 14, hence into the dried process process of next group.
After the moisture content that the dry materials of last batch are needed to default, the first discharging opening 16 is opened, starts first
Conveyer 12 and second conveyer 14, the material for having dry are concentrated in by the first air deflector 13 and the second air deflector 15
Discharge bucket 17, is then shut off the first discharging opening 16, opens the second discharging opening 18 and takes out material, is then turned off the second discharging opening
18.Therefore, the drying process operation of the material to whole batches is realized.
It should be noted that for the present invention, terminating until the material of all batches all dries, Analysis of Heat Pump Drying System is all the time
Work, to maintain its inside to have higher drying air temperature and relatively low humidity, and vacuum system is then simply dry in heat pump
Start during vacuum degree deficiency in drying system.
In sum, compared with prior art, a kind of continuous type heat pump vacuum drier that the present invention is provided,
Which can be while realizing carrying out continuous drying process to multiple batches of material, it is ensured that during material is changed, it is to avoid
Cause unnecessary energy resource consumption and thermal loss, at the same avoid the oxygen being rich in extraneous air directly with drying box in treat
Dry material comes in contact, and reduces the oxidation reaction for occurring, and so as to ensure the nutrient composition content inside material, is conducive to wide
The popularization and application of general ground, are of great practical significance.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
