Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] figure 1 It is a schematic diagram of a tape casting machine drying box with heat energy recovery function in the present invention, including a drying tunnel 3, an air supply fan 1, a heating box 2, an exhaust fan 5, a return air fan 4, and a hot air recovery heat exchanger 6. The drying tunnel 3 is provided with an air inlet, an exhaust outlet and a return air outlet. The air outlet of the air supply fan 1 is connected to the air inlet of the drying tunnel 3 through the heating box 2, and the return air outlet on the drying tunnel 3 is connected to the return air through the return air channel. The air inlet of fan 4 is connected, and the air outlet of return air fan 4 is connected with the air inlet of drying tunnel 3 . The air outlet of the drying tunnel 3 is connected with the air inlet of the exhaust fan 5 through the air exhaus...

Abstract

The invention discloses a tape casting machine drying oven with a heat recovery function and a drying method. According to the invention, heat of damp-hot air in the tape casting machine drying oven can be recycled, energy consumption can be reduced and the effect of energy saving is further achieved. An air outlet of an air supply fan is connected with an air inlet of a drying tunnel through a heating box, a return air port of the drying tunnel is connected with an air inlet of a return air fan through a return air channel, an air outlet of the return air fan is connected with the air inlet of the drying tunnel; an air exhaust port of the drying tunnel is connected with an air inlet of an air exhaust fan through an air exhaust channel, one path of an air outlet of the air exhaust fan is connected with the air inlet of the air supply fan through a first air valve, the other path of an air outlet of the air exhaust fan is connected with an air exhaust inlet of a hot air recovery heat exchanger through a second air valve, and a fresh air outlet of the hot air recovery heat exchanger is connected with the air inlet of the air supply fan through a third air valve. The drying oven can send the damp-hot air to the air supply fan through the air exhaust fan and directly send the exhausted damp-hot air to the drying tunnel, thus reaching the purposes of hot air heat recovery and energy saving.

Description

technical field [0001] The invention relates to a drying box of a tape casting machine and a drying method with the function of recovering heat energy. Background technique [0002] The cast film cast by the cast machine enters the drying oven for drying. At present, the drying tunnel of the drying box of the tape casting machine is provided with an air inlet, an exhaust outlet and a return air outlet. The air supply fan is connected to the air inlet on the drying tunnel through the heating box, and the fresh air is heated and sent to the drying tunnel. The hot air flows in the drying tunnel, and a part of the hot and humid air is sent to the air inlet of the drying tunnel through the return air fan to realize the hot air circulation, which is beneficial to the drying of the cast film; the other part of the hot and humid air is discharged through the exhaust outlet. The hot and humid air discharged through the air outlet has a high temperature and has a certain amount of he...
