An infrared spectrum dryer

Abstract

The invention discloses an infrared spectrum drier. The infrared spectrum drier comprises a rack, an infrared heating device and a workpiece conveying mechanism, wherein a drying cavity is formed in the rack, the workpiece conveying mechanism is arranged at the bottom of the rack, and the two ends of the workpiece conveying mechanism extend out of the rack; one side of the rack is sequentially provided with a first heating ventilating opening, a first exhaust inlet and a second exhaust inlet from the end where a workpiece is conveyed in to the end where the workpiece is conveyed out, and a first draught fan is arranged on the rack; an exhaust ventilating opening opposite to the first heating ventilating opening, a second heating ventilating opening opposite to the first exhaust inlet, and a third exhaust inlet opposite to the second exhaust inlet are formed in the side face, opposite to the first heating ventilating opening, of the rack; an infrared heating cavity is further formed between an inlet of a second draught fan and the third exhaust inlet, and the exhaust ventilating opening is communicated with a chimney. The infrared spectrum drier is provided with only one drying cavity and thus is small in size, the heat efficiency of the drier is high because of the infrared heating cavity, heating speed is high, heat efficiency is high, running cost is low, the drying effect is good, the size of the drying cavity can be changed, and the heat energy utilization rate can be improved.

Description

technical field [0001] The invention relates to a drying device, in particular to an infrared spectrum drying machine. Background technique [0002] In existing mechanical processing, coolant is usually used to prevent overheating damage to the machining tool. After the machining is completed, a layer of coolant will adhere to the surface of the workpiece. The adhesion of coolant to the surface of the workpiece will not only make the workpiece unclean but also easily cause corrosion on the surface of the workpiece. In order to solve the above problems in the existing production, it is necessary to dry the workpiece after processing. The traditional drying treatment equipment is a gas drying furnace. The traditional gas drying furnace has a large volume and requires a long production line, with low thermal efficiency and high operating costs. Due to the use of gas combustion to provide heat energy, the carbon dioxide emissions are high, the heating speed is slow, and the util...

Problems solved by technology

The traditional gas drying furnace has a large volume and requires a long production line, which has low thermal efficiency and high operating costs. Due to the use of gas combustion to provide heat energy, the carbon dioxide emissions are high, the heating speed is slow, and the heat energy utilization rate is low.

Traditional gas heating has low wind speed and poor drying effect
