The working principle is as follows:
when the device needs to be used, firstly, a worker connects the cement inlet pipe 47 and the cement outlet pipe 49 with an external pipeline respectively, and then the device is connected with an external power supply;
at the moment, the pipe inlet valve 48 is manually opened by a worker, cement enters the box body 1 through the cement inlet pipe 47, after the cement is injected, the pipe inlet valve 48 is manually closed by the worker, and the worker controls the driving motor 11 to start working through the control switch;
along with the work of the driving motor 11, the driving motor 11 drives the worm gear reducer 13 to rotate, so that the rotating speed of an output shaft is reduced, the output end of the worm gear reducer 13 drives the driving stirring gear 14 to start rotating, the driven stirring gear 10 drives the air injection inlet pipe 9 to rotate through the engagement of the driving stirring gear 14 and the driven stirring gear 10, the air injection sleeve shaft 3 rotates through the connection of the air injection inlet pipe 9 and the air injection sleeve shaft 3, so that the air injection sleeve shaft 3 drives the inclined stirring air injection shaft 7 to rotate, the inclined stirring air injection shaft 7 is driven to rotate along with the air injection sleeve shaft 3, so that cement in the box body 1 is stirred, and cement oxygen is stirred through the stirring of the cement;
the rotation of the driving motor 11 drives the driving pulley 12 to start rotating, and the driving pulley 12 drives the driven pulley 30 to rotate through the transmission of the driving belt 31, while the rotation of the driven pulley 30 drives the transmission shaft 28 to rotate, the rotation of the transmission shaft 28 drives the driving bevel gear 29 to start rotating, and the driven bevel gear 25 drives the rotating shaft 23 to rotate through the engagement of the driving bevel gear 29 and the driven bevel gear 25, so that the rotating shaft 23 drives the rotating end of the supercharging worm wheel 16 to start rotating, and the impeller inside the supercharging worm wheel 16 starts rotating at high speed along with the rotation of the rotating end of the supercharging worm wheel 16, so that the supercharging worm wheel 16 starts to extract air to the outside through the supercharging air inlet pipe 17, and the mesh drying box 19 and the renewable drying agent 20 inside the square-cone-shaped containing box seat 18 arranged at one end of the supercharging air inlet pipe 17 dry the outside air, after being dried, outside air enters a pressurizing air outlet pipe 21 through the work of a pressurizing worm wheel 16, then enters an air injection inlet pipe 9 through the pressurizing air outlet pipe 21, then enters an air injection sleeve shaft 3 through the air injection inlet pipe 9, then enters a conical air injection seat 5 and an inclined stirring air injection shaft 7, the dried air is injected through an air injection nozzle I6 on the conical air injection seat 5, so that the air is blown towards cement below the center of the box body 1, and meanwhile, the dried air is injected through an air injection nozzle II 8 on the inclined stirring air injection shaft 7, so that the air is blown towards the cement inside the box body 1;
through the work of the driving motor 11, the air injection sleeve shaft 3 drives the inclined stirring air injection shaft 7 to rotate to stir the cement, and the air injection nozzle I6 and the air injection nozzle II 8 simultaneously inject dry normal-temperature air, so that the dry normal-temperature air can blow the cement dust and lift the cement dust, the contact area of the dry normal-temperature air and the cement dust is increased, and the cooling efficiency of the cement is ensured;
with the continuous injection of the dry normal temperature air, the dry normal temperature air absorbs the heat in the cement dust through the contact with the cement dust, so as to reduce the temperature of the cement dust, so that the cement dust is cooled, then the dry hot air enters the discharge casing 32 through the continuous injection of the air, the cement dust in the hot air is primarily filtered through the multi-layer fan-shaped filter screen 36 arranged in the discharge casing 32, so as to reduce the content of the cement dust in the hot air, then the hot air is filtered again through the filter element 39, so as to reduce the content of the cement dust in the hot air again, so that the content of the dust in the discharged hot air reaches the emission standard requirement, and then the filtered hot air enters the discharge pipe 46 through the discharge casing 32 and is discharged to the outside through the discharge pipe 46;

in the process, the annular piston baffle 33 is still positioned in the discharge casing 32, so that hot air can still be filtered through the filter element 39 in the discharge process, thereby avoiding leakage of cement dust and ensuring normal discharge of the hot air, after the cement dust is cleaned, the electric telescopic rod 45 is controlled to work again through the control switch, the electric telescopic rod 45 drives the annular piston baffle 33 to start to ascend, all the piston baffles 34 are retracted into the discharge casing 32, and the device is recovered to the original shape;
at this moment, the worker controls the driving motor 11 to stop working through the control switch, at this moment, the worker can open the outlet pipe valve 50 manually, and at this moment, the worker can discharge the cooled cement through the outlet pipe valve 50.
