The present invention adopts following technical scheme: a kind of cereal residual heat pump dryer, comprise casing, and the flabellum be arranged in casing left end, and the evaporimeter be arranged on the right side of flabellum, and the first electric control valve be arranged on the right side of evaporimeter, and the condenser be arranged on the right side of the first electric control valve, and connect the cold coal carrier pipe of evaporimeter and condenser, and the throttling arrangement be arranged on cold coal carrier pipe, receiver and compressor, and the second electric control valve be arranged on the right side of condenser, and be arranged on the air outlet at casing top, and the return air inlet be arranged on the right side of air outlet.
Further, be provided with blower fan in described air outlet, described blower fan is for regulating air supply velocity.
Further, described first electric control valve arranges equal with the width of the second electric control valve, the described first electric control valve both sides that are arranged on condenser corresponding with the setting height(from bottom) of the second electric control valve; Described first electric control valve is for the exhaust air rate that dehumidifies, and described second electric control valve is for regulating new wind intake.
Further, described air outlet and return air inlet form circulation air path.
A kind of cereal residual heat pump dryer of the present invention, comprise casing, and the flabellum be arranged in casing left end, and the evaporimeter be arranged on the right side of flabellum, and the first electric control valve be arranged on the right side of evaporimeter, and the condenser be arranged on the right side of the first electric control valve, and connect the cold coal carrier pipe of evaporimeter and condenser, and the throttling arrangement, receiver and the compressor that are arranged on cold coal carrier pipe, and the second electric control valve be arranged on the right side of condenser, and be arranged on the air outlet at casing top, and be arranged on the return air inlet on the right side of air outlet.The present invention is by the adjustable dehumidifying exhaust air rate of the first electric control valve, the adjustable new wind intake of second electric control valve, the adjustable air supply velocity of blower fan, three combines the efficiency of heating surface of adjustable condenser to wind, reach steady temperature air-out, air outlet and return air inlet form circulation air path, reclaim the waste heat of discharging, improve the effect that condenser heats wind, reach energy-conservation effect, improve the task performance ratio of main frame, achieve remaining recovery utilization rate high, reduce outer row, can Quick for the heat energy of temperature constant, firing rate is fast, environmental protection and energy saving, structure is simple, easy to operate, production cost is low.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of cereal residual heat pump of the present invention dryer.
Detailed description of the invention
In the present embodiment, with reference to shown in Fig. 1, a kind of cereal residual heat pump dryer, comprise casing 1, and the flabellum 2 be arranged in casing 1 left end, and the evaporimeter 3 be arranged on the right side of flabellum 2, and the first electric control valve 4 be arranged on the right side of evaporimeter 3, and the condenser 5 be arranged on the right side of the first electric control valve 4, and connect the cold coal carrier pipe 6 of evaporimeter 3 and condenser 5, and the throttling arrangement 7 be arranged on cold coal carrier pipe 6, receiver 8 and compressor 9, and the second electric control valve 10 be arranged on the right side of condenser 5, and be arranged on the air outlet 11 at casing 1 top, and the return air inlet 12 be arranged on the right side of air outlet 11.
