Detailed description of the invention
Frame mode of the present utility model is illustrated below in conjunction with accompanying drawing.
A kind of heat pump drying system, comprise the multiple drying chambers 10 be connected in series successively, be equipped with the transmission guipure 6 for convey materials in each drying chamber, transmission guipure 6 is provided with mesh that can be ventilative, and the size of mesh should not be less than material.In previous drying chamber, the discharge end of transmission guipure is connected to the feed end of the transmission guipure in next drying chamber by pay-off 13.The independent warm-air supply mechanism controlled is equipped with in each drying chamber 10.The air outlet of warm-air supply mechanism is positioned at the below of drying chamber 10, is also provided with the air draft mechanism for discharging humid air above drying chamber.
Described warm-air supply mechanism is provided with pressure fan 5, hot-air channel 8 and heat pump 4.Described hot-air channel connects with the condenser 11 of heat pump 4, forms the heat exchanger being used for the heat of condenser medium being passed to air-flow in hot-air channel.Air-flow crosses hot-air channel carry out heat exchange with the condenser 11 of heat pump 4 the driving of pressure fan 5 is dirty, and air-flow is blown in drying chamber by the hot blast heating rear formation from the air outlet of hot-air channel 8, to complete the oven dry to material.In order to make air flow method even, the air outlet of hot-air channel be provided with for by hot blast along the scattered air-distribution device of transmission guipure width.
Described air draft mechanism is provided with wet-emitting blower 3 and air exhaust passage 9, and the moisture in material is taken out of rapidly by the hot blast of warm-air supply mechanism blowout in the process of moist material, forms damp-heat air.Damp-heat air is driven by wet-emitting blower 3 and enters dehumidifier 2 through air exhaust passage 9.This dehumidifier 2 can be made up of with air exhaust passage 9 evaporimeter 12 of heat pump 4 as shown in Figure 3.Also can be the heat exchanger that as shown in Figure 5 one has hot and humid gas passage and heat exchanging medium passage, air exhaust passage 9 be connected to hot and humid gas passage, and heat exchanging medium passage and evaporimeter 12 form a heat exchanger again.By heat, the heat transferring medium be passed in heat exchanging medium passage realizes the condensation of moisture to damp-heat air, and heat transferring medium is heated up.Dewatered air enters hot-air channel from hot and humid gas passage again, thus realizes circulating of dry gas.Heat exchanging medium passage connects with the evaporimeter 12 of heat pump again, and the heat of heat transferring medium is passed to evaporimeter medium.Heat is passed to the medium in evaporimeter by heat transferring medium, after the compressor compresses of heat pump, again enter condenser 11, forming hot blast, achieving again the circulation of heat thus for adding hot-air.
Multi-layer transmission guipure 6 is provided with from top to bottom in drying chamber.The hot blast of warm-air supply mechanism blowout from the bottom to top successively through transmission guipure, and is discharged by air draft mechanism.The transmission guipure of the superiors docks with this drying chamber feeding mouth 1, undermost transmission guipure docks with the discharging opening of this drying chamber, the throughput direction of adjacent two layers transmission guipure is contrary, and the feed end of lower floor's transmission guipure protrudes from the discharge end of upper strata transmission guipure in the horizontal direction.The material that upper strata transmission guipure discharge end is fallen drops down onto on lower floor's transmission guipure, and is oppositely carried by lower floor's transmission guipure, forms the reciprocating motion of material in drying chamber thus, to extend material transport path, thus makes full use of limited land resource.
Consider that material its volume after thermal dehydration can reduce in various degree, for the harmony guaranteed to be heated material on guipure hot blast penetrates, the guipure speed of service of different warm areas and different dryer section should control in the different speeds of service, to guarantee the harmony that material stone is harmonious and dry, thus in each drying chamber 10, the speed of service of transmission guipure 6 also controls separately.The harmony penetrated to keep hot blast, on the throughput direction of material, the transporting velocity of different transmission guipure increases and decreases little gradually, enable the transmission guipure of throughput direction upstream faster by the transmission guipure of material fed downstream, thus material is piled up on downstream drive guipure, to compensate the volume-diminished of material further.
In order to make up the deficiency of heat pump temperature, auxiliary heater 7 can also be set in hot-air channel, adopt Electric heating auxiliary heating, according to required bake out temperature, heat pump and auxiliary heating dual system auto-changeover control.Described wet-emitting blower 3 can be arranged on the uptake of dehumidifier, also can be arranged on lower air port.
Described warm-air supply mechanism is also provided with the heat pump assembly extracting thermal source from air or water, and the evaporimeter of this heat pump assembly and air or water carry out heat exchange.
Removably connect between described multiple drying chambers, thus arbitrarily can move this cover drying production line, reduce user because of Various Seasonal, Different sources and build the cost of multiple production line, reduce the idleness of equipment cost that the Seasonal Production feature because of crops causes.
