Abstract

The invention discloses an aluminum oxide breaking and unloading device and an aluminum oxide breaking and unloading integrated method for an aluminum electrolysis cell. The aluminum oxide breaking and unloading device comprises a gas cylinder, a drive piston, a material tank, a charge piston, a discharge piston, a constant volume chamber, a solenoid valve, a material collecting cavity, a hammer head rod, an outer steel sleeve, an unloading tube, a steel barrel, a hammer head, a beam and a bracket. The aluminum oxide breaking and unloading device is characterized in that the hammer head rod and the hammer head which is connected with the hammer head rod are mounted inside the material collecting cavity and the unloading tube, uniform unloading of aluminum oxide is realized, the aluminum oxide is prevented from being unloaded in a stacked manner, and the aluminum oxide is uniformly dispersed into an electrolyte, so that the dissolving capacity of the electrolyte to the aluminum oxide is improved, the anode effects are reduced and the furnace-bottom precipitates are reduced. Meanwhile, the breaking and unloading devices are combined into a whole, so that the equipment cost is reduced and the equipment mounting and maintaining are convenient. The device can scrape off housing package heads which are adhered on the hammer head and the outer steel barrel, so that the labor intensity of a worker is relieved and the service life of the device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of aluminum electrolysis, and in particular relates to an integrated device and method for shelling and unloading of aluminum oxide in an aluminum electrolytic cell. Background technique [0002] Point-type blanking technology is a major breakthrough in modern aluminum electrolysis technology. At present, the point-type feeding device is composed of two parts: a shelling device and a feeding device. The shelling device realizes opening a hole on the crust surface of the electrolytic cell, and the feeding device realizes passing the alumina in the constant volume chamber. The opened pores discharge into the electrolyte. The shelling device is composed of a shelling cylinder and a hammer head. The hammer head is connected with the cylinder piston through the hammer head rod. When the cylinder piston moves, it drives the hammer head to move up and down to strike the crust on the surface of the electrolyte; the...
