s7, when the two moving plates (8) are close to each other, the slag which is not pushed can fall into the second collecting tank (12) from the opening;
s8, as the limit plate (18) is arranged, slag can accurately fall into the first collecting tank (11);
s9, after the slag is discharged, closing the electric telescopic rod (13), and then pulling the first collecting tank (11) upwards to separate the two positioning columns (16) from the clamping of the two positioning grooves respectively;
and S10, sliding the two fixing rods (17) to move the two fixing rods (17) in the direction away from each other, so that the two fixing rods (17) are respectively separated from the clamping of the two fixing grooves.
7. The slagging method of a water seal tank of a rotary hearth furnace according to claim 6, wherein in S4, the inner walls of both sides of the water seal tank main body (2) are brushed, so that the slag adhered to the inner walls can be removed and the slagging is more complete.
8. The slagging method of the water seal tank of the rotary hearth furnace according to claim 6, wherein in S10, the two first collecting tanks (11) and the second collecting tank (12) are taken down, the slag is intensively treated, and the slag in the water seal tank main body (2) can be discharged in time through the steps, and the slagging is thorough without affecting the operation of the rotary hearth furnace main body (1).
