Dryer provided with uniform air distributing system

Abstract

The invention relates to a dryer, in particular to a dryer provided with a uniform air distributing system. The dryer comprises a rack, wherein a drying box is continuously arranged on the rack in thelongitudinal direction, and a conveying belt penetrating through the inner cavity of the drying box is arranged on the rack. A hot air device is connected to one side of the drying box, and an air outlet and an air return port are formed between the hot air device and the drying box and are located on the upper side and the lower side of the conveying belt. The dryer is characterized in that an air distributing plate is arranged in the drying box portion between the air outlet and the conveying belt and is uniformly provided with through holes. The distance between the air distributing plateand the conveying belt is gradually increased from one side to the other side of the air outlet, so that the air distributing plate is obliquely arranged, and the periphery of the air distributing plate is in sealed connection with the inner wall of the drying box. The dryer can conduct uniform air distribution on hot air introduced into the drying box, uniform material drying is achieved, and theoperating efficiency is improved.

Description

technical field [0001] The invention relates to a dryer, in particular to a dryer with a uniform air distribution system. Background technique [0002] As we all know, the dryer is a very common industrial material drying equipment. When it works, the material is located above the bed board in the body and moves along the longitudinal direction of the dryer with the bed board. At this time, the drying device is used to introduce hot air to the material to achieve the purpose of drying the material. [0003] Traditional drying devices for dryers include a burner and an induced draft fan installed outside the drying box and connected in series through pipes. The induced draft fan introduces the hot air heated by the burner into the drying box to dry the material, and then The relatively low temperature cold air in the drying box is guided back to the burner through the return air duct for heating. This cycle realizes the continuous drying operation of the materials in the dr...

AI Technical Summary

Problems solved by technology

However, due to the large space in the drying box, the hot air introduced by the induced draft fan is often not evenly distributed to every corner of the drying box, which causes the materials in the area near the air outlet to be fully or even excessively Drying, but the insufficient drying of materials in the area far from the air outlet makes local materials dry unevenly, requiring secondary operations, which affects work efficiency

At the same time, the structure in which the heater directly heats the return air absorbed through the pipe and then discharges the air makes the temperature of the hot air entering the drying box from the air outlet too high, which often causes excessive drying of the material and even damages the quality of the material. The composition of the tissue reduces the amount of finished products in a single drying operation of the material, which not only wastes resources, but also reduces the efficiency of the drying operation
