Energy-saving airflow drying box

Abstract

The invention discloses an energy-saving airflow drying box, which comprises a box body, elastic supports, a placement screen plate, drying air pipes, an air pump, a heating box, a drying and cleaningbox, a water tank and a heat exchange pipe. The elastic supports are arranged on two sides in the box body; the placement screen plate is arranged on the elastic supports; the drying air pipes are arranged in the box body; the air pump, the heating box and the drying and cleaning box are arranged on the box body; an air inlet is formed in the left end of the heating box; heating rods are connected into the heating box; a vent hole is formed between the heating box and drying and cleaning box; the water tank is arranged on the right side of the box body; the heat exchange pipe is arranged in the water tank; an air inlet pipeline is connected between the upper end of the heat exchange pipe and a right wall of the box body; an air outlet pipeline is connected to the right side of the lower end of the heat exchange pipe; and an upper cover is connected to the upper end of the water tank. According to the energy-saving airflow drying box provided by the invention, a material can be uniformly dried through a clean air flow, and the efficiency is improved through telescopic shaking of the elastic supports; and the waste heat of a high-temperature tail gas is fully utilized by utilizing the heat exchange pipe, so that the energy-saving airflow drying box is energy-saving and environmentally-friendly on the basis of ensuring favorable drying.

Description

technical field [0001] The invention relates to an energy-saving drying device, in particular to an energy-saving airflow drying box. Background technique [0002] Drying ovens are divided into two categories: electric blast drying ovens and vacuum drying ovens according to different drying materials. They have been widely used in chemical industry, electronic communications, plastics, cables, electroplating, hardware, automobiles, optoelectronics, rubber products, Mold, spraying, printing, medical, aerospace and colleges and universities and other industries. The huge market demand makes the varieties of drying ovens diversified, and the construction quality of the products is also not the same. [0003] When the existing drying device is drying the material, the purification of the drying gas is insufficient, and it is difficult to avoid the entry of impurities in the air during the drying process, which may affect the processing quality of the material; when the existing...
