The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 1 to Fig. 3, pump type heat grain drying machine, comprise heat pump drying unit 1 and the drying tower 2 being connected with described heat pump drying unit 1, at described heat pump drying unit, comprise air inlet 10, described heat pump drying unit 1 comprises at least one refrigerant circulation loop, described refrigerant circulation loop comprises compressor 11, cross valve 12, condenser 13, device for drying and filtering 14, heating power expansion valve 15, evaporimeter 16, described compressor 11, cross valve 12, condenser 13, device for drying and filtering 14, heating power expansion valve 15, evaporimeter 16 is connected to form closed circuit successively, described heat pump drying unit 1 also comprises air circulation duct, described air circulation duct comprises the pipeline being communicated with described air inlet 10, described device for cleaning pipeline is crossed condenser 13 and and described drying tower 2 connections of each refrigerant circulation loop.
In described heat pump drying unit 1 bottom, be provided with roller 17, unit can be moved freely.
At described heat pump drying unit 1, be positioned at described air inlet 10 places and be provided with the first blower fan (accompanying drawing does not show), utilize described the first blower fan better surrounding air to be imported to heat exchange in dryer.
At described heat pump drying unit 1 top, be provided with air-ducting ring 18 and the second blower fan (accompanying drawing does not show), in refrigerant circulation loop, cold, by the second blower fan, is discharged to air and goes from air-ducting ring.
