An on-line automatic dryer for cuttings, including a channel-shaped bin body 2 arranged on the top of a conveyor 1. A hot air supply assembly is arranged on one side of the top of the bin body 2 close to the discharge end of the conveyor 1. The air outlet end of the hot air supply assembly is located on the inner side wall surface of the bin body 2 and faces directly above the conveyor 1. An air extraction and dehumidification assembly is arranged at a position on the top of the bin body 2 close to the feeding end of the conveyor 1. Rubber dust-proof curtains 3 are provided at both open ends of the bin body 2. A material raking assembly is arranged on the frame of the conveyor 1. During use, the cuttings samples after being washed and cleaned enter the bin body 2 through the conveyor 1. The hot air supply assembly blows hot air towards the position of the cuttings samples. Under the action of the hot air, the moisture attached to the surface of the cuttings evaporates. At the same time, the air extraction and dehumidification assembly is started. The wet air carrying a large amount of moisture further enters the air extraction and dehumidification assembly to remove the moisture, and then the dry gas containing a certain amount of heat flows back into the hot air supply assembly, which can effectively improve the drying efficiency and at the same time increase the initial temperature of the air in the heating bin 4, and can effectively reduce the energy consumption during the drying process. In addition, rubber dust-proof curtains 3 are provided at both ends of the bin body 2, which can effectively reduce heat loss and further improve the thermal energy utilization rate during the drying operation. At the same time, in cooperation with the material raking assembly to turn and rake the cuttings on the conveyor 1, the drying efficiency can be further improved; after testing and inspection, by making adaptive adjustments to the cloth thickness, the feeding speed of the conveyor 1, the operating power of the hot air supply assembly and the air extraction and dehumidification assembly, continuous one-time drying operations for a large number of cuttings can be achieved.

[0016] In the specific implementation process, as a preferred setting, the above-mentioned hot air supply component includes a heating chamber 4, a blower 5, a distribution air duct 6, and an injection air duct 7.

The injection air duct 7 is arranged on the inner wall of the bin body 2 and is communicated with the distribution air duct 6. The side wall of the injection air duct 7 is provided with an air injection pipe 8 inclinedly. A temperature sensor is arranged in the heating chamber 4. Among them, the air extraction and dehumidification component includes an air collecting hood 9, a negative pressure axial flow fan 10, a steam-water separator 11, and a return air duct 12. The air collecting hood 9 is arranged in the bin body 2. The air inlet end of the negative pressure axial flow fan 10 is connected to the air collecting hood 9. The inlet of the steam-water separator 11 is connected to the air outlet end of the negative pressure axial flow fan 10. One end of the return air duct 12 is connected to the outlet of the steam-water separator 11 and the other end is communicated with the hot air supply component. During use, start the electric heating wires on the inner side wall surface of the heating chamber 4, use the electric heating wires to heat the air inside the heating chamber 4, then start the blower 5, use the blower 5 to inject the high-temperature air into the injection air duct 7 through the distribution air duct 6 respectively, and make the high-temperature air further blow to the cuttings on the conveyor 1 through the air injection pipe 8. Then use the high-temperature gas to evaporate the moisture. While the blower 5 is operating, start the negative pressure axial flow fan 10, use the air pressure to suck out the high-temperature and humid gas inside the bin body 2 and inject it into the steam-water separator 11. The dried gas flows back to the heating chamber 4 through the return air duct 12, which can increase the initial temperature of the air in the heating chamber 4 and further effectively reduce the energy consumption during the drying process.

[0017] In the specific implementation process, the above-mentioned material raking component includes a support 13, a cross beam 14, and a material raking member.

Among them, the material raking member includes a rake claw 15 and a spring 16. The upper end of the rake claw 15 is hinged to the cross beam 14 and the lower end is in contact with the moving surface of the conveyor 1. The spring 16 is arranged obliquely and the upper and lower ends are respectively connected to the cross beam 14 and the side wall of the rake claw 15. During use, the moving surface of the conveyor 1 drives the cuttings into the bin body 2. During the movement of the cuttings, while drying with the high-temperature air, the cuttings come into contact with the rake claws, and the rake claws are used to turn and rake the cuttings, continuously plowing the cuttings into different thin strips, increasing the evaporation area while avoiding the accumulation of cuttings, which can further improve the drying operation efficiency.
