Compared with prior art, a kind of energy saving heat pump dryer that the utility model is provided has the advantages that:
The energy saving heat pump dryer makes air formation closed cycle in baking room, and the fresh air for preventing high humility halfway enters, And the air in baking room continues removal moisture drying, it will so accelerate drying rate;And because the air in baking room is by one Become more and more drier after secondary removal again, therefore without very high temperature dried material moisture can be allowed to dry, so dried Dry material will not because temperature is too high and change colour, it is rotten or even become ripe and influence to be oven-dried the quality of thing, by the material of drying The effect dried of the quality infinite approach sun.The energy saving heat pump dryer application heat pump is heated with process of refrigerastion while depositing Natural quality, take full advantage of its cold and hot energy so that the system energy consumption is relatively low, and efficiency is higher.
The energy saving heat pump dryer scheme that the utility model is provided overcomes the deficiencies in the prior art, applies heat pump in work Heated in work simultaneously while the self attributes freezed, make full use of its heat energy and cold energy energy to realize dehumidifying drying.Mainly Feature is power consumption is low, drying is fast, drying temperature is low, device manufacturing process is simple etc..
Brief description of the drawings
Fig. 1 is a kind of schematic diagram just of the energy saving heat pump dryer of embodiment of the utility model,
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 schematically shows a kind of energy saving heat pump dryer according to a kind of embodiment of the present utility model, should Dryer is applicable various material drying.As illustrated, the device includes baking room 1 and a heat pump main frame.
Wherein, heat pump main frame includes main frame evaporator 2 and compressor 3.
Baking room 1 dries the parking space 1a of material provided with air handling space 1b and for depositing.
Parking space 1a and air handling space 1b are mutually isolated.
Air-supply passage 14 is provided with above parking space 1a.
Air-supply passage 14 is connected with air handling space 1b.
Air handling space 1b and parking space 1a interconnected return air channels 15 formed below.
The inside of air-supply passage 14 is provided with least one set of heat pump condenser 12.
Return air channel 15 is provided with least one set of evaporator with heat pump 13.
Blower fan 11 is additionally provided between evaporator with heat pump 13 and heat pump condenser 12.
When blower fan 11 works, air is blowed into heat pump condenser 12, heat pump condenser 12 is used to heat air-flow, entered Cross the air after heating to send into parking space 1a by air-supply passage 14, air is passed through by return air channel 15 in parking space 1a Space 1b is handled by the air inlet of evaporator with heat pump 13, then heat pump condenser 12 will be blowed to by blower fan 11, thus air is in air Circulated between processing space 1b and parking space 1a.
Damp-heat air temperature reduction, hydrogenesis therein when by evaporator with heat pump 13 after parking space 1a On evaporator with heat pump 13.
Heat pump condenser 12 by refrigerant pipe 4 with evaporator with heat pump 13 be connected.
Refrigerant pipe 4 is by way of being in series with throttling arrangement, liquid-sighting glass and device for drying and filtering.
Evaporator with heat pump 13 is connected with main frame evaporator 2, and heat pump condenser 12 is connected with compressor 3.
The lower section of evaporator with heat pump 13 is additionally provided with water-collecting tray 131, and water-collecting tray is by a drainpipe 132 by collection therein Condensed water is discharged into outside baking room 1.
Heat pump condenser 12 in air-supply passage 14 is connected with the exhaust end of compressor 3, optionally may dress in the middle of it Provided with other auxiliary accessories such as oil eliminator, valve, compressor 3 will form the refrigerant of HTHP after gaseous coolant media collapse Gas, is carrying out heat exchange with blowing toward the air in baking room 1 by heat pump condenser 12, is releasing heat and be heated to air to set Constant temperature degree, while HTHP coolant media is cooled to condense into liquid refrigerants.Liquid refrigerants flows down in the driving of its high pressure Vaporific gas-liquid mixed coolant injection is formed after the throttling arrangement of refrigerant pipe 4 to evaporator with heat pump 13 with described baking room 1 Interior damp-heat air carries out heat exchange, and damp-heat air is cooled to condensation and condenses out water droplet by absorption heat, while vaporific gaseous state is cold Matchmaker's heat absorption starts evaporation.Now evaporator with heat pump 13 is designed as incomplete evaporation because of only exsiccation is played, and multiple heat pumps steam Hair device 13 can be connected with main frame evaporator 2 in parallel or serial fashion, and the mixed state refrigerant of non-evaporating completely delivers to main frame Evaporator 2 continues to flash to the gaseous coolant of certain degree of superheat, and compressor 3 is sent to after necessary auxiliary accessories and is pressed again Contracting.
The moisture of dried material evaporation in the parking space 1a of baking room 1 is mixed into wet with the hot-air in its space Air passes through evaporator with heat pump 13, heat pump in the presence of the blower fan 11 being installed in air handling space 1b from return air channel 15 The heat exchange amount of evaporator 13 is to be calculated by design and surface temperature can be made to be less than humid air dew point, and humid air stream is through described Evaporator with heat pump 13 when vapor condense into water droplet to the cold and be collected into the water-collecting tray (131) of the lower section of evaporator with heat pump 13, Condensed water is discharged through the drainpipe 132 installed in the lower of water-collecting tray 131 again.
Meanwhile, humid air is changed into dry air after isolating moisture and described heat pump condensation is sent in the presence of blower fan 11 Device 12 is heated, and the dry air after heating is assigned to parking space 1a by air-supply passage 14, and is blowed to and dried with rational orientation Dry, makes moisture in dried material evaporate again.So circulation reaches the purpose of material drying.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art, On the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this practicality New protection domain.
