FIELD: metallurgy.SUBSTANCE: device includes a manifold pipe having many holes made in its wall at a certain distance from each other, a suction pump, a suction pipe, one end of which is connected to the suction pump and an assembly of a suction head. The suction head assembly is connected to the other end of the suction pipe and is capable of moving in a sliding manner along the manifold pipe from one of its ends to the other. The suction head assembly includes a head section of the housing, which is spatially remote and connected to a rear section of the housing, which has a through axial hole interconnected with the suction pipe. Head and rear sections of the housing fill a considerable part of the manifold pipe during operation and form a suction zone between themselves of such length that at least one hole can be open at location of the suction head assembly at certain positions along the manifold pipe. The method is implemented by means of a device for removal of slurry and consists in installation at the bottom of a sediment tank or a pond of a manifold pipe, connection of the suction pump to one end of the suction pipe, connection of the suction head assembly to the other end of the suction pipe by means of a through axial hole in the rear section of the housing. After that, the suction head assembly is introduced into an open end of the manifold pipe. Besides, front and rear sections of the housing considerably fill the manifold pipe and form a suction zone between them of such length that at least one hole can be open in any position along the manifold pipe. The suction head assembly is moved through the through holes of the manifold pipe at subsequent passage of the working suction pump above holes in the manifold pipe wall.EFFECT: improving slurry removal efficiency.21 cl, 6 dwg |
