Abstract

The utility model discloses a heat pump drier which relates to a device for drying materials and objects, which is characterized in that a drying chamber, an evaporator chamber, a blower and a condenser chamber are connected in series end to end through air tubes; a compressor, a condenser, a throttling gear and an evaporator are connected in series end to end through refrigerant conduit tubes; a heater is arranged in the drying chamber; and an air inlet of the blower is connected with the evaporator chamber. The utility model uses the heat pump principle for forming the low temperature in the evaporator chamber for promoting the separation of moisture in the air, and simultaneously, the heat produced by the condenser is recovered into the drying chamber for promoting the evaporation of moisture in the dried objects. In the process for drying the dried objects, no heat is discharged out, and no external air enters the heat pump drier. Thereby, compared with the prior art, the utility model saves a large amount of energy sources, and avoids the pollution on the dried objects.

Description

The heat-pump-type drying device

Technical field

The utility model relates to and a kind of the material article is carried out dry device, especially can play energy-saving and cost-reducing a kind of heat-pump-type drying device.

Background technology

At present, be applied to the traditional drying device of every profession and trades such as industrial and mineral and service, no matter be to be made of hothouse, heater, exhaust system, be to adopt which kind of mode such as electricity, steam, far infrared to heat, in order to reduce the humidity in the hothouse, to accelerate rate of drying, have to discharge in a large number air and steam after being heated in the hothouse, thereby wasted a large amount of energy, strengthened production cost, simultaneously, replenish the pollution that a large amount of surrounding airs that enter also cause the article that are dried easily.

Summary of the invention

In order to overcome the deficiency that existing drying device wastes energy and easily the article that are dried polluted, the utility model provides a kind of heat-pump-type drying device, and this heat-pump-type drying device not only can be saved energy and reduce the cost, and can prevent the pollution to the article that are dried.

The technical scheme that its technical problem that solves the utility model adopts is: hothouse, evaporator room, blower fan, the condenser chamber is by the end to end closed circuit that is cascaded and forms air of airduct, compressor, condenser, throttling arrangement, evaporimeter constitutes heat pump simultaneously by the end to end closed circuit that is cascaded and forms cold-producing medium of coolant conduits, evaporimeter is installed in the evaporator room, it is indoor that condenser is installed on condenser, discharge outlet is installed on the bottom of evaporator room, heater is installed on the bottom of hothouse, the installation direction of blower fan enters the condenser chamber after should making the interior wind of airduct be introduced into evaporator room again, the outlet of compressor links to each other with an end of condenser, the import of compressor links to each other compressor with an end of evaporimeter, condenser, throttling arrangement, evaporimeter, be marked with cold-producing medium in the refrigerant circulation loop that coolant conduits forms.After adding material in the hothouse, at first carry out preheating by heater, after reaching preset temperature, stop heating, unlatching is by compressor, condenser, throttling arrangement, heat pump and blower fan that evaporimeter constitutes, air in the hothouse just begins via evaporator room, blower fan, the condenser chamber is got back to hothouse and is moved in circles, because compressor, condenser, throttling arrangement, the heat pump that evaporimeter constitutes can make the evaporimeter indoor temperature reduce in running, simultaneously, the condenser indoor temperature raises, therefore, the air of process evaporator room will be lowered the temperature and be separated out most of contained humidity, the water of separating out is discharged from discharge outlet, air after the quilt cooling is got back in the hothouse after heating up via the condenser chamber again, continuous circulation along with dry room air, the moisture that is dried in the article will constantly be taken away by air and separate out in evaporator room, therefore reached the dry goods purpose, in dry run, leak owing to noenergy, realized energy-saving and cost-reducing, whole dry run is carried out under an airtight environment, has avoided the pollution to the article that are dried.

The beneficial effects of the utility model are, when reaching dry goods, have realized energy-saving and cost-reducingly, have avoided the pollution of environment to the article that are dried, and meet the fundamental policy of current country and worldwide energy-saving and emission-reduction.
