The invention relates to a continuous-working
defrosting device for a quick-freeze storage. The continuous-working
defrosting device comprises a compressed-air
defrosting component, a thermal-insulation storage body, an air injection tank component, an air injection tank component reversing transmission mechanism, a water defrosting
system and an automatic water retaining device and is characterized in that the compressed-air defrosting component comprises an air
storage tank, the lower end of the air
storage tank is provided with an automatic
water discharge valve, and the upper end of the air
storage tank is provided with a pressure gauge, a
safety valve and a pressure
transmitter. The continuous-working defrosting device has the advantages that the device is especially suitable for a super-long
evaporator, low-pressure
compressed air is used for performing blow
drying after defrosting, nozzles are close to the
evaporator, fast blow
drying is achieved, the large-flow rotary nozzles are mounted on the guide rail of the air injection tank component, structure compactness is achieved, air injection tank reversing uses a special double-proximity-switch
control manner, work reliability and maintenance convenience are achieved, and the automatic-control water retaining device is used during
evaporator water defrosting to prevent low-temperature
discharge water from splashing aroundto cause mesh belt
icing.
