Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

Referring to Fig. 1, a kind of heat pump dryer, including the drying baker 7 on the right side of source pump and source pump, described heat pump Unit includes compressor 1, the sender property outlet of described compressor 1 11 by heat pump circuits 2 be sequentially connected with condenser 3, economizer 5, The working medium import 12 of vaporizer 6 and compressor 1 also forms loop；Described condenser 3 there is also an arm, institute with economizer 5 State and on arm, be provided with expansion valve 4；Described economizer 5 upper end is connected with the sender property outlet 11 of compressor 1 by heat pump circuits 2； Being provided with the dividing plate 71 of vertically layout in described drying baker 7, all there is gap, institute with drying baker about 7 two ends in described dividing plate 71 Stating dividing plate 71 and will be separated into main drying 72 chamber and secondary drying cavity 73 in drying baker 7, described condenser 3 is arranged in secondary drying cavity 73 Portion；It is provided with circulating fan 74 in the secondary drying cavity 73 of described condenser 3 upper end, is provided with bottom the described main right wall of drying cavity 72 Exhaust blower 8, is provided with exhaust duct 82 at described exhaust blower 8, it is outer and right along drying baker 6 that described exhaust duct 82 extends to drying baker 6 Wall and end face are laid, and described exhaust duct 72 is provided with exhaust valve 81；Described drying baker 7 upper end is provided with horizontally disposed air intake Pipe 9, in described blast pipe 9 is arranged at exhaust duct 82 and extend to main drying cavity 72 top, described blast pipe 9 is provided with air intake Valve 91.

Operation principle of the present utility model is: the cold-producing medium working medium of low-pressure low-temperature is done work by compressor 1, is compressed to height The gas of temperature high pressure enters condenser 3, and in condenser 3, wet stock is done to cold dry air by the substantial amounts of heat of working medium releasing Dry, and the reduction of working medium own temperature becomes high pressure middle temperature saturated solution, a part is directly entered economizer 5, a part of expanded valve 4 Entering economizer 5 after throttling cooling further, go to reduce the temperature of another part, the subcooled liquid settled out is through vaporizer 6 Become the saturated air of low-temp low-pressure, then pass to the working medium import 12 of compressor 1, and the uncooled gaseous refrigerant of another part It is directly connected to the sender property outlet 11 of compressor 1 by economizer 5, reenters compressor 1 circulation compression.

During work, circulating fan 74 action in secondary drying cavity 73, under the driving effect of circulating fan 74, main drying cavity 72 realize circulating with the air in secondary drying cavity 73, the cold-producing medium circulated heat release to pair when flowing through condenser 3 Circulation air in drying cavity 73 carries out continuous heating, and finally makes the temperature in drying baker reach the requirement of material drying； When main drying cavity 72 internal temperature reaches design temperature, close compressor 1, and keep circulating fan 74 to continue to run with；Wait to lead When the interior humidity of drying cavity 72 is higher, open exhaust valve 81 and air inlet valve 91, start moist empty by drying baker 7 of exhaust blower 8 Gas is discharged, and in negative pressure in drying baker 7, and is introduced by extraneous cold dry air by blast pipe 9, reaches the effect of dehumidifying；Air intake The cold dry air of pipe 9 is heated by the damp-heat air of exhaust duct 82 during entering drying baker 7, arrives the effect of preheating, has Effect utilizes waste heat, energy-conserving and environment-protective；Described drying baker 7 is made up of complex heat-preservation styrofoam, and composite polyphenylene plate enhances drying baker 7 Heat insulation effect, further reduce the loss of heat energy.

This new structural design is reasonable, easy to use, pollution-free, and efficiency is high, it is achieved desiccant dehumidification, reclaims in air simultaneously Waste heat be circulated utilization, energy-conserving and environment-protective；By the setting of economizer, improve power system capacity and efficiency.
