Description

Technical Field

[0001] This utility model relates to the field of heat pump drying equipment technology, and in particular to a drying equipment capable of efficient dehumidification. Background Technology

[0002] A heat pump dryer is a heat-lifting device that uses the reverse Carnot principle to extract heat from the surrounding environment and transfer it to the object being heated (an object with a higher temperature). Its working principle is the opposite of that of a refrigeration machine.

[0003] A search revealed a Chinese patent (application number "202221382475.8") disclosing "a heat pump drying device." This heat pump drying device includes a shell with a first chamber and a second chamber; the second chamber has a dehumidifying air inlet; the first chamber has an air outlet with an internal fan installed at the outlet; a heat pump system including a compressor, a condenser, a throttling device, and an evaporator connected in sequence; the condenser is located in the first chamber, and the evaporator is located in the second chamber; the first chamber has a bypass vent with an adjustable airflow guide; and a heat exchanger with a hot air channel and a cold air channel. The hot air channel connects the dehumidifying air inlet and the air inlet side of the evaporator, while the cold air channel connects the air outlet side of the evaporator and the air inlet side of the condenser. However, during use, this heat pump drying device does not pre-dehumidify the humid hot air discharged from the drying chamber, causing moisture to accumulate on the evaporator. This prevents the evaporator from fully absorbing heat from the outside air, resulting in low practicality. Utility Model Content

[0004] This utility model provides a drying device that can efficiently dehumidify, solving the problem proposed in the prior art that the heat pump drying device does not pre-dehumidify the humid hot air discharged from the drying chamber when drying materials, causing moisture to accumulate on the evaporator and preventing the evaporator from fully absorbing heat from the outside air, resulting in low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency dehumidifying drying device includes a casing. A partition is welded to the inner wall of the middle section of the casing, and a compressor is bolted to the inner wall of the bottom of the casing. An evaporator, a condenser, and a heat exchanger are bolted to the outer wall of the top of the partition. A hot air duct is fixed to the upper inner wall of one side of the casing, and a return air duct is fixed to the lower inner wall of one side of the casing. A dehumidification mechanism is provided at the bottom of the partition, and the dehumidification mechanism includes several corrugated dehumidification plates. A collection box is welded to the outer wall of the bottom of the partition. A filtration mechanism is provided at the top of the partition, and the filtration mechanism includes a mounting frame and a filter frame embedded in the mounting frame. A blower mechanism is provided at the top of the partition, and the blower mechanism includes a duct fan.

[0007] Preferably, two doors are hinged to one outer wall of the chassis, and several channel steels are welded to the bottom outer wall of the chassis.

[0008] Preferably, the compressor is connected to the evaporator via copper pipes, and the compressor is connected to the condenser via copper pipes. The condenser is connected to the heat exchanger via copper pipes, and the heat exchanger is connected to the evaporator via an expansion valve.

[0009] The above scheme involves the evaporator absorbing heat from the air inside the casing, followed by the heat exchange medium being transported to the compressor. The compressor compresses the heat exchange medium, further increasing its heat content. The heat exchange medium then enters the condenser to release heat, and the released heat exchange medium exchanges heat with the heat exchanger again. Hot air is then transported to the drying chamber through a hot air duct, and the cooled heat exchange medium is returned to the evaporator through an expansion valve.

[0010] Preferably, an installation plate is bolted to the bottom outer wall of the partition, and several dehumidification plates are respectively fixed to the bottom outer wall of the installation plate. An air supply pipe is fixed to the inner wall of one end of the bottom of the collection box, and the top end of the air supply pipe is fixed to the top outer wall of the partition. A drain pipe is fixed to the inner wall of the bottom of the collection box, and the drain pipe is connected to a drain pump.

[0011] The above method involves drawing humid, hot air from the drying chamber into the collection box via a return air duct. The humid, hot air impacts the dehumidification plate, which traps the moisture due to inertia. The moisture drips down the dehumidification plate into the collection box, where a drain pump discharges the water.

[0012] Preferably, a connecting block is slidably fitted through the upper outer wall of the chassis, and the mounting frame is bolted to the bottom outer wall of the connecting block. A fixing plate is bolted to the top outer wall of the connecting block, and the fixing plate is bolted to the top outer wall of the chassis. A handle is bolted to the top outer wall of the fixing plate.

[0013] Preferably, a mounting base is bolted to the top outer wall of the partition, and the mounting base is bolted to one inner wall of the chassis, and the duct fan is bolted to the outer wall of one side of the mounting base.

[0014] The above method filters the hot air discharged from the air duct through a filter frame to remove impurities from the hot air in the drying room, and then the duct fan delivers the hot air back to the evaporator.

[0015] The beneficial effects of this utility model are as follows:

[0016] The return air duct draws humid, hot air from the drying chamber into the collection box. The humid, hot air impacts the dehumidification plate, which traps moisture due to inertia. The moisture drips down the dehumidification plate into the collection box, where a drain pump discharges the water. This process dehumidifies the hot air returning from the drying chamber, preventing large amounts of water vapor from condensing on the evaporator and hindering its ability to fully absorb heat from the outside air, thus improving practicality.
