Space-adjustable back suction type high-efficiency hot air drying box equipment

Abstract

The invention discloses space-adjustable back suction type high-efficiency hot air drying box equipment which comprises a box body, wherein a drying cylinder is arranged at the bottom of the box body; a bottom ventilation clearance is formed between the drying cylinder and the bottom surface of the box body, and an annular side ventilation clearance is formed between the drying cylinder and the inner wall of the box body; a lift circulation air suction device is arranged at the upper end of the drying cylinder; a moisture elimination cylinder is arranged at the upper end of the lift circulation air suction device; the lift circulation air suction device is controlled to go up and down by a lift cylinder; an electrical heating wire board is arranged at the bottom of the drying cylinder; a placing board is arranged in the drying cylinder; the lift circulation air suction device comprises a lift air suction cylinder at the bottom of the lift circulation air suction device and an air suction impeller in the lift circulation air suction device, and the upper end of the lift air suction cylinder is connected with a moisture absorption cylinder through an air duct; a separation disk is arranged on the cylinder wall of the moisture absorption cylinder; the moisture absorption cylinder is filled with aluminum silicate fibers; ventilation holes are uniformly formed in the air duct; the moisture elimination cylinder is arranged at the top end of the moisture absorption cylinder; an exhaust fan is arranged in the moisture elimination cylinder. According to the space-adjustable back suction type high-efficiency hot air drying box equipment disclosed by the invention, multi-direction wind power circulation drying can be realized, the drying efficiency is high, the exhaust speed of vapor is high, a drying space is adjustable, and the use is flexible and convenient.

Description

technical field [0001] The invention belongs to the technical field of hot air boxes, in particular to space-adjustable back-suction type high-efficiency hot air drying box equipment. Background technique [0002] The space of the hot air circulation cavity inside the traditional hot air circulation oven is fixed, which is suitable for heating and drying ordinary batch materials. Due to the fixed space, the efficiency of heating and drying will be greatly reduced when there are fewer materials put in, and the traditional The air direction of the hot air circulation oven is generally vertical circulation or horizontal circulation, which cannot realize the all-round enveloping and flowing drying of the materials by the wind force, which reduces the drying speed of the materials. At the same time, the moisture taken away by the drying of the materials cannot be effectively removed, making the water in the oven There is a lot of steam, the discharge speed is slow, and the hot ai...

[0002] The space of the hot air circulation cavity inside the traditional hot air circulation oven is fixed, which is suitable for heating and drying ordinary batch materials. Due to the fixed space, the efficiency of heating and drying will be greatly reduced when there are fewer materials put in, and the traditional The air direction of the hot air circulation oven is generally vertical circulation or horizontal circulation, which cannot realize the all-round enveloping and flowing drying of the materials by the wind force, which reduces the drying speed of the materials. At the same time, the moisture taken away by the drying of the materials cannot be effectively removed, making the water in the oven There is more steam, the discharge speed is slower, and the hot air chamber is in direct contact with the outside world, which cannot effectively isolate bacteria
