Air guiding and moisture exhausting roller drier

Abstract

The invention discloses an air guiding and moisture exhausting roller drier. The roller drier comprises a bearing base rack, a rotary roller, a drying box and hot air blowers, wherein the drying box is fixedly installed on the bearing base rack, the rotary roller is arranged in the drying box, an air guiding groove is formed in the inner side wall of the drying box, the hot air blowers are arranged at the upper end of the drying box, the two hot air blowers are the first hot air blower and the second hot air blower, the first hot air blower is arranged towards the left side, the second hot air blower is arranged towards the right side, one end of each hot air blower is arranged on the drying box in a sealed mode, an air outlet is formed in the other end of each hot air blower, the air outlets are communicated with the air guiding groove, the hot air blowers exhaust air to the air guiding grove through the air outlets, hot air guiding holes are further formed in the air guiding groove and protrude out of the air guiding groove to be arranged towards the interior of the drying box, and a plurality of moisture exhausting and heat dissipating holes are further formed in the top of the drying box and are respectively in the shape of an inverted horn. Due to the mode, directional hot air guiding and moisture exhausting can be performed, and influences caused when hot moisture flows back into the drying box are avoided.

Description

technical field [0001] The invention relates to the field of dryers, in particular to an air-guiding and dehumidifying tumble dryer. Background technique [0002] Drum dryer is one of the traditional drying equipment, which is reliable in operation, flexible in operation, strong in adaptability, and large in processing capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, chemical fertilizer, ore, sand, clay, kaolin, sugar, etc. field. The wet material entering the drying cylinder is picked up and thrown down repeatedly by the drum wall, and is broken into fine particles by the dispersing device during the falling process. The heating area is greatly increased, and it is more likely to be dried when it is in full contact with the hot air. However, the heat conduction and moisture dissipation of traditional dryers are not designed in a directional way, and it is difficult to fully dissipate the moisture in the dryer, so that part of ...

AI Technical Summary

Problems solved by technology

However, the heat conduction and moisture dissipation of traditional dryers are not designed in a directional way. It is difficult to fully dissipate the moisture in the dryer, so that part of the moisture will flow back into the drying box and cause the objects to get wet again, which will affect the drying work.
