Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in drawings：A kind of drying system of crops heat pump 11, including drying chamber 1, drying unit and controller 10,
The temperature sensor 17 being connected with controller 10 is provided with the drying chamber 1；The drying unit includes being arranged on drying chamber 1
Side and circulating fan 9, condenser 12 and two heat pumps 11 being connected with controller 10, the circulating fan 9, heat pump 11 and cold
The air inlet 6 and air outlet 13 of condenser 12 and drying chamber 1 are sequentially connected；The drying chamber 1 is provided with for connecting exhaust fan 8
Outer row's mouth 5, the exhaust fan 8 is connected with controller 10, and check valve 7 is provided with the discharge pipe of the exhaust fan 8；Institute
State in drying chamber 1 and be additionally provided with carbon dioxide extinguisher installation.
Be provided with deflector in the drying chamber 1, the deflector include being separately mounted to the front side of drying chamber 1, upside with
And front flow guiding plate 15, baffle upper plate 3 and the rear deflector 18 of rear side.
Drying chamber 1 is divided into air intake passage 2 and baking zone 18 by the baffle upper plate 3 and rear deflector 15, described leading
Baking zone 18 is separated out air-out passage 14 by flowing plate 18；On the baffle upper plate 3, rear deflector 15 and front flow guiding plate 18 respectively
Begin with bleeder port, conduction hole and exhaust vent.
The front flow guiding plate 15 is provided with several rows of exhaust vents 16, and often the quantity of row exhaust vent 16 is sequentially reduced from top to bottom, by
The downside of air-out passage 14 is arranged in air outlet 13, therefore the thermal current in drying baker easily concentrates on bottom, and from up to
Under the gross area of every row exhaust vent 16 be sequentially reduced, can be very good to ensure that the material of drying baker the upper side and lower side can be uniform
Drying.
Number is set to arrange uniform bleeder port 4 on the baffle upper plate 3, the gross area of the bleeder port 4 is the face of baffle upper plate 3
Long-pending 5%, such design not only can effectively prevent that the air pressure of this section of air intake passage 2 is too high, and can avoid from bleeder port
The hot gas flowed out in 4 is excessive, and causes the hot gas deficiency flowed out from rear deflector 18, and then influences the uniformity of drying.
Gap is left between the rear end of baffle upper plate 3 and drying baker squab panel；Uniformly opened on deflector 18 after described
Conduction hole 20 is arranged provided with number；The downside of deflector 18 is placed in the 3rd mounting groove after described, and the rear upside of deflector 18 is arranged on upper
The rear end of deflector 3；Angle after described between the upside of deflector 18 and squab panel is 10 °.

Residing for 18 during air intake passage 2, conduction hole 20 that can be preferentially from the upside of deflector rearward 18 flow out, when after deflector 18 be obliquely installed
When, side opening increases on rear deflector 18 and drying baker rear wall, so that more hot blasts can be from being arranged on rear deflector 18
The conduction hole 20 of downside flows out.
Operation principle and using method of the present utility model：
1st, when starting drying, after opening heat pump 11 and circulating fan 9, hot blast enters air intake passage 2, hot blast from air inlet
When flowing through 3 sections of air intake passages 2 of baffle upper plate, because blast is higher, part hot blast can flow from the bleeder port 4 of baffle upper plate 3
Enter baking zone 18；After hot blast enters after 18 sections of air intake passages 2 of deflector, it can be flowed into from the conduction hole 20 on rear deflector 18
Baking zone 18；Hot blast after being dried to the material in baking zone 18 flows into air-out passage from the venthole on front flow guiding plate 15
After 14, then vapor liquid in the presence of condenser 12 from the inflow condenser 12 of air outlet 13 on air-out passage 14, hot blast
Change and discharge, condensed 12 dried hot blast of device is again introduced into heat pump 11 and heated, and is sent into by circulating fan 9 in drying baker；
2nd, the specific control method of the drying system is as follows：
（1）, when starting working, controller 10 controls two heat pumps 11 and circulating fan 9 to open work, makes drying chamber 1
Interior temperature is lifted rapidly；When temperature is close to preset value, controller 10 controls a heat pump 11 to keep it turned on, another heat pump 11
Close, make in drying chamber 1 temperature stabilization near preset value；
（2）, when the temperature that this is detected is less than preset value, controller 10 control heat pump 11 improve heating power, so as to
Lift drying the temperature inside the box；When temperature is less than default low temperature warning value, controller 10 controls two heat pumps 11 to open simultaneously
Beginning work so that misreading in drying baker can go up rapidly；
（3）, when detect drying the temperature inside the box it is too high when, temperature controller 10 control heat pump 11 reduce heating power, and
The rotating speed of circulating fan 9 is improved, reduces the temperature in drying baker；When detecting that drying the temperature inside the box exceedes warning value, control
Device 10 processed controls air exhauster to start working, and high temperature air is discharged from check valve 7, so as to prevent drying the temperature inside the box mistake
It is high.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and be carried out, the scope of protection of the utility model can not be limited with this,
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover the scope of protection of the utility model it
