Detailed Description

The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.

As shown in fig. 1 to 4, the environment-friendly concrete drying device of the embodiment includes a feeding chamber 1 and a drying chamber 2, a feeding channel 3 is arranged in the feeding chamber 1, and a spiral conveying device 4 is arranged below the feeding channel 3. The screw conveyor 4 is horizontally arranged, the discharge port 41 of the screw conveyor 4 is positioned in the drying chamber 2, the screw conveyor 4 comprises a conveying channel 42 and a screw 43, and the screw 43 is arranged in the conveying channel 42. An air inlet 5 and a filtering system 6 are arranged in the drying chamber 2, the filtering system 6 is arranged at the top of the drying chamber 2, and the air inlet 5 is arranged at the bottom of the drying chamber 2. The filtering system 6 comprises a plurality of filters 61, an air pipe 62 and an air source 63, wherein the filters 61 are communicated with the air outlet 21, the air source 63 is communicated with the air pipe 62, and the air pipe 62 extends into the filters 61. In the above technical scheme, when the material is dried, the material enters the conveying channel 42 through the feeding channel 3, and the material is conveyed to the drying chamber 2 through the screw 43. The air inlet 5 in the drying chamber 2 inputs air flow with a certain temperature, and the air flow enables the temperature of the conveying channel to rise and enables the temperature of the drying chamber to rise simultaneously, so that drying is achieved. The air inlet can provide hot air flow by arranging a fan and an electric heating device, and can also directly convey the hot air flow through an external heat source.
