DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0018] Reference Figure 1-Figure 3A quicklime spiral dosing device with a purging function comprises a conveying pipeline 1, a conditioning tank 3, and a quicklime silo 4. The conveying pipeline 1 is erected above the conditioning tank 3. A material port is opened on the conveying pipeline 1. A quicklime silo 4 is fixed in the material port by bolts to facilitate feeding into the conveying pipeline 1. Quicklime is put into the quicklime silo 4, and the quicklime enters the conveying pipeline 1 through the quicklime silo 4. A material guiding device is provided inside the conveying pipeline 1. An annular purging device 8 is installed inside the conveying pipeline 1 near both ends to purge the quicklime powder attached to the conveying pipeline 1. A plurality of annular purging device air outlets 9 are opened at the bottom of the annular purging device 8, and the annular purging device air outlets 9 are evenly distributed.

[0019] In the utility model, the material guiding device is a conveying screw 6, and the internal rotation of the conveying pipe 1 is connected to the transmission shaft 7, and the conveying screw 6 is installed on the transmission shaft 7. The outer wall of one end of the conveying pipe 1 is fixed with a motor 5 by bolts, and one end of the output shaft of the motor 5 passes through the conveying pipe 1 and is fixed with the transmission shaft 7. Two discharge holes are provided at the bottom of the conveying pipe 1, and discharge pipes 2 are fixed in the discharge holes by bolts. The rotation of the motor 5 causes the transmission shaft 7 to drive the conveying screw 6 to rotate, and the rotation of the conveying screw 6 causes the quicklime entering the conveying pipe 1 to be discharged into the conditioning tank 3 from the discharge pipes 2 at both ends.

[0020] In the utility model, the top of the annular purging device 8 passes through the conveying pipeline 1 and is fixedly connected with a quick connector 10. The inside of the quick connector 10 is fixedly connected with a gas source pipeline 11 to facilitate the external airflow to be transmitted to the annular purging device 8 through the gas source pipeline 11. A valve 12 is installed on the top of the gas source pipeline 11 to control the gas flow output by the gas source pipeline 11. After the quicklime is added, the gas source pipeline 11 is connected with the external airflow generator, and the valve 12 is opened. The airflow flows through the gas source pipeline 11 to the annular purging device 8, and then is discharged through multiple annular purging device outlets 9 to completely blow away the quicklime powder adhering to the inner wall of the conveying pipeline 1.

[0021] Working principle: When in use, quicklime is added through the quicklime silo 4, and the quicklime enters the conveying pipeline 1 through the quicklime silo 4, and the motor 5 is started. The motor 5 rotates to make the transmission shaft 7 drive the conveying screw 6 to rotate, and the conveying screw 6 rotates to make the quicklime entering the conveying pipeline 1 be discharged into the conditioning tank 3 from the discharge pipes 2 at both ends. After the quicklime is added, the air source pipeline 11 is connected with the external air flow generator, and the valve 12 is opened. The air flow flows through the air source pipeline 11 to the annular purge device 8, and then is discharged through multiple annular purge device outlets 9, and the quicklime powder adhering to the inner wall of the conveying pipeline 1 is completely purged to avoid the quicklime powder clogging the inner wall of the conveying pipeline 1 and the discharge port, thereby affecting the discharge.
