Detailed Description

The invention will be described in more detail with reference to the following embodiments:

the sintering machine head ash stirrer shown in fig. 1 comprises a barrel body 1, a rotating shaft 2 and a stirring paddle 3, wherein the upper end of the barrel body 1 is opened, a discharge pipe 1-1 is arranged at the lower end of the barrel body 1, and a valve 1-2 is arranged on the discharge pipe; the upper end of the barrel body 1 is provided with a motor support 4, a motor 5 is positioned on the motor support 4, an output shaft of the motor 5 extends downwards to be connected with one end of a rotating shaft 2, the motor 5 is controlled by frequency conversion, a stirring paddle 3 is arranged in the barrel body 1, and the other end of the rotating shaft 2 is connected with the stirring paddle 3; the inner wall of the barrel body 1 is connected with a stirring barrel 7 for isolating sintering machine head ash through a stirring barrel support 6, one end of the stirring barrel support 6 is fixedly connected with the inner wall of the barrel body 1, the other end of the stirring barrel support 6 is fixedly connected with the outer wall of the stirring barrel 7, the stirring barrel 7 is sleeved outside the rotating shaft 2 and the stirring paddle 3, and the central axis of the stirring barrel 7 is coincided with the central axes of the barrel body 1 and the stirring paddle 3; the mixing drum 7 has good selectivity on the sintering machine head ash which is not soaked, so that the sintering machine head ash is easy to soak, and the shearing force of mixing is enhanced; a flow guide disc 8 for guiding the sintering machine head ash to move upwards along the inner wall of the barrel body 1 is arranged below the mixing barrel 1, the flow guide disc 8 is a circular flow guide disc, the flow guide disc 8 enhances the separation of the sintering machine head ash which is not soaked, and the concentrated treatment of the sintering machine head which is not soaked after being selected is ensured; the inner wall of the barrel body 1 is provided with the flow stabilizing plate 9, the length direction of which is the same as the axial direction of the barrel body 1, and the flow stabilizing plate 9 is used for eliminating rotational flow when sintering machine head ash moves upwards, so that the rotational flow is weakened by the flow stabilizing plate 9, the flow path of mortar and the time for enabling non-soaked sintering machine head ash to enter the inner mixing drum again for mixing are shortened, and the mixing efficiency is improved.

When the stirring device works, the motor output shaft rotates to drive the stirring paddle to rotate to stir the sintering machine head ash, the vertical central axis of the stirring cylinder is coincided with the central axis of the stirring paddle, the stirring paddle pushes mortar to flow downwards when rotating, most of non-infiltrated sintering machine head ash (containing bubbles with low specific gravity) moves upwards along the inner wall of the barrel body under the isolation action of the stirring cylinder and the guide action of the guide disc, and the infiltrated sintering machine head ash moves downwards along the inner wall of the barrel body due to high specific gravity and is discharged through the discharging pipe and the valve; and the non-infiltrated sintering machine head ash moves upwards under the isolation of the mixing drum and the guidance of the flow guide disc, and after the rotational flow is eliminated through the flow stabilizing plate, overflows from the upper edge of the mixing drum, the newly added sintering machine head ash is driven to enter the mixing drum together, so that the mixing paddle stirs the sintering machine head ash violently, the non-infiltrated sintering machine head ash is infiltrated into mortar, and then the mortar is discharged to the next process through a discharge pipe and a valve, and the process is repeated.

The utility model discloses under the combined action of the isolation of churn and churn, guiding disk and stabilizer, not only reduced the re-stirring to the sintering machine head ash that has soaked, eliminated the invalid short path of mortar upper and lower circulation flow, and force the sintering machine head ash that the hydrophobicity is strong and not soaked to concentrate and get into the churn by the churn top edge in, the selective violently stirs to the sintering machine head ash that does not soak, strengthened the infiltration process to the sintering machine head ash that does not soak, the effectual infiltration time that shortens, the stirring efficiency is improved, the electric energy loss is reduced, manufacturing cost is reduced; simultaneously, the stirring rake is rotatory at a high speed in the churn, makes to form certain negative pressure in the churn, inhales the churn with the raise dust in the barrel, gets into solution under the high-speed stirring effect of stirring rake, has effectively eliminated the raise dust, has avoided the pollution of environment and the worsening of air.
