Description

Crust breaking hammer head of aluminum electrolytic cell

Technical Field

The utility model relates to the field of electrolytic aluminum, in particular to a hammer head used for striking and breaking electrolyte crusting in the industrial production of aluminum electrolysis so as to discharge aluminum or feed materials.

Background

During the electrolytic aluminium production process, a relatively hard electrolyte crust forms inside the cell. The electrolyte crust is very hard and needs to be punched with holes on the crust surface by hammering through a crust breaking device. The part of the crust breaking device which is directly contacted and crusts is a crust breaking hammer, and the shape and the structure of the crust breaking hammer directly influence the crust breaking effect.

The existing crust breaking hammer head is generally made of solid steel, and can be divided into the following cases according to different shapes. The first is that the crust breaking hammer is cylindrical. For example, publication No. CN205688037U discloses an adjustable crust breaking device, including crust breaking cylinder, crust breaking cylinder's piston rod is fixed with the articulated joint, and the articulated joint is articulated with the nut, and crust breaking head hammer stem upper portion is provided with the threaded rod with nut complex, and the crust breaking tup is cylindrical. The patent with publication number CN205635807U discloses a tool for cleaning an aluminum outlet and a crust-breaking hammer head of an aluminum cell, which is used for manually cleaning incrustation on the aluminum outlet and scale on the crust-breaking hammer head, and the crust-breaking hammer head is cylindrical. The second type is that the crust breaking hammer is in a round table shape. For example, patent No. CN210560802U discloses an intelligent crust breaking device for an electrolytic cell, wherein the crust breaking hammer head is in a circular truncated cone shape, a bottom surface with a relatively large area of the circular truncated cone is connected with a hammer rod, and a bottom surface with a relatively small area of the circular truncated cone is a hammering surface. And the third is that the crust breaking hammer is conical. For example, the patent with publication number CN 201574198U discloses a novel electrolytic cell crust breaking hammer head, which is divided into a cylindrical hammer body and a cross-shaped conical impact head, the two parts are of an integrated structure, and the cross-shaped conical impact head is used for directly hammering and crusting.

To above-mentioned current crust-breaking tup, the hole size of beating is unanimous with the diameter of tup, and the single can't beat the hole bigger than the tup diameter. In order to punch a large hole on the surface of the crust, a hammer with a larger diameter is generally used, but after the diameter of the hammer is increased, the contact area is increased during hammering, and the hammering crust is not easy to break through.
