Description

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The dryer heats the material to vaporize the moisture (generally water or other volatile liquid components) in order to obtain solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. According to the operating pressure;

[0003] The drying barrel of the traditional dryer needs to be connected to a fan, and an electric heating device is set between the fan and the drying barrel, so that the fan inputs hot air into the drying barrel to achieve the purpose of drying the plastic raw materials. Since the fan continuously inputs gas into the drying barrel, an exhaust port is generally set on the drying barrel to maintain the air pressure balance in the drying barrel. Therefore, the heat in the drying barrel will be continuously lost. This design cannot make good use of the heat in the drying barrel;

[0029] The activated carbon 5 is fixedly connected to the slider 10, and the number of the slide grooves 9 and the slider 10 are both two groups and are symmetrically distributed.

[0030] The outer surface of the upper end of the chassis 1 is rotatably connected with a reciprocating screw rod 6 , the upper end of the reciprocating screw rod 6 penetrates into the inner side of the guide tube 8 , and the slider 10 is connected to the reciprocating screw rod 6 in a spiral transmission manner.

[0032] By adopting the above technical scheme, when the machine body is working, the hot air inside the chassis 1 will move upward inside the chassis 1 and enter the drying cylinder 3 through the air guide holes 4 on the upper side of the chassis 1. Then the activated carbon 5 in the drying cylinder 3 will filter and dry the hot air. The activated carbon 5 can fully absorb the moisture and impurities in the air, thereby ensuring the purity of the hot air. When the hot air passes through the air guide holes 4 upward, it will drive the blades 7 to rotate. During the rotation of the blades 7, the reciprocating screw 6 will be driven to rotate.

Then the activated carbon 5 in the drying cylinder 3 will filter and dry the hot air. The activated carbon 5 can fully absorb the moisture and impurities in the air, so as to ensure the purity of the hot air. When the hot air passes through the air guide hole 4 upward, it will drive the blade 7 to rotate. During the rotation of the blade 7, the reciprocating screw 6 will be driven to rotate. The slider 10 is connected with the reciprocating screw 6 through the spiral transmission and slides along the slide groove 9 as the reciprocating screw 6 rotates. During the movement of the slider 10, it will drive the activated carbon 5 to reciprocate up and down. Through the up and down vibration of the activated carbon 5, it can The dust and impurities adsorbed on the surface of the activated carbon 5 are shaken off, and the hot air filtered and adsorbed by the activated carbon 5 will enter the guide tube 11 from the drying cylinder 3, and the hot air will be guided to the fixed tube 13 by the guiding effect of the guide tube 11. The partition 14 in the fixed tube 13 will have a certain blocking effect on the hot air, so that the hot air is discharged from the notch 15 on the surface of the fixed tube 13 to the outer sleeve 12.
