Heat pump heat supply type drying device

Abstract

The invention discloses a heat pump heat supply type drying device. The heat pump heat supply type drying device comprises a base. Side seats are arranged on the two sides of the base, lifting clamping seats are arranged at the inward face positions of the side seats, top seats are arranged on the tops of the side seats, and a clamping cavity is formed between the top seats and the lifting clamping seats. Hydraulic cylinders are arranged at the inward face positions of the side seats, piston rods are arranged on the upper portions of the hydraulic cylinders, and the ends of the piston rods aremounted at the bottoms of the lifting clamping seats. A drying shell is arranged above the base, the drying shell is mounted between the side seats, a cavity structure is arranged in the drying shell, multiple hot air holes are formed in the top face of the drying shell, and multiple heat pumps are mounted in the drying shell. A guide pipe is arranged on the base, an internal thread pipe is is sleeved with the guide pipe, and the upper end of the internal thread pipe is mounted at the bottom of the drying shell. The drying shell can be conveniently controlled to achieve vertical lifting adjusting, and the relative distance between the drying shell and a to-be-treated plate is conveniently adjusted; and the intensity of hot air drying treatment on the plate by the drying shell is conveniently adjusted.

Description

technical field [0001] The invention relates to a drying device, in particular to a heat pump heating drying device. Background technique [0002] The heat pump is essentially a heat raising device. The high-temperature heat pump dryer unit uses the reverse Carnot principle to absorb heat from the surrounding environment and transfer it to the heated object. Traditional heat pump dryers are basically open-loop drying. At present, with everyone's attention to drying quality, closed-loop dehumidification heat pump dryers have become a new trend and hot spot because of their low energy consumption and high quality. Replacing the traditional open-loop heat pump dry high-temperature heat pump drying unit, it mainly consists of four parts: finned evaporator, compressor, finned condenser and expansion valve. The thermodynamic cycle process of evaporation transfers the heat from the external low-temperature environment to the drying room, and the refrigerant circulates in the syste...

AI Technical Summary

Problems solved by technology

The existing heat pump dryer is inconvenient for positioning and installation of the panels, and does not have the vertical lifting adjustment mechanism of the hot air dryer, so the efficiency of thermal drying of the panels is low
