Structure for reducing melt wrappage adhesion of crust breaking chips

Abstract

The invention discloses a structure for reducing melt wrappage adhesion of crust breaking chips. The structure comprises the crust breaking chips body, a hammer rod, a scraper, a sleeving, a cross-shaped notch, hammer rod holes, scraper holes and sleeving holes, wherein the crust breaking chips body and the hammer rod are connected into a whole, the crust breaking chips body is sleeved with the scraper, the hammer rod is sleeved with the sleeving, the scraper and the sleeving are arranged into a whole, and specifically, the cross-shaped notch is formed in the end part, close to the hammer rod,of the crust breaking chips body, the hammer rod holes are formed in the hammer rod in the axial direction at equal intervals, the hammer rod holes are formed in the circumferential direction of thehammer rod in a circumferential array mode, the scraper holes are further formed in the scraper, and the sleeving holes are formed in the sleeving. The structure for reducing the melt wrappage adhesion of the crust breaking chips has the advantages that flowing airflow can be fully utilized to cool the hammer rod of the chips body, the probability of the melt wrappage adhesion of the crust breaking chips body is effectively reduced, and stable operation of an electrolytic cell crust breaking and discharging system can be favorably maintained.

Description

technical field [0001] The invention relates to the technical field of electrolytic aluminum production and processing, in particular to a shelling hammer for an aluminum electrolytic cell. Background technique [0002] The shelling and cutting system of the electrolytic cell includes 4 to 7 shelling hammers, which are driven by compressed air to quickly strike the shell surface at intervals of about one minute. Start feeding after a few seconds. However, in actual production, due to factors such as changes in compressed air pressure, fluctuations in the total height of the melt, adjustment of tank temperature and molecular ratio, etc., the shelling hammer is very easy to stick to the bag, even if a scraper is installed, it cannot solve the problem. The problem. [0003] If the hammer head dipping bag is not treated in time, it will continue to grow larger, which not only hinders the alumina feeding, easily leads to the lack of material in the electrolytic cell and the ano...

Problems solved by technology

However, in actual production, due to factors such as changes in compressed air pressure, fluctuations in the total height of the melt, adjustment of tank temperature and molecular ratio, etc., the shelling hammer is very easy to stick to the bag, even if a scraper is installed, it cannot solve the problem. The problem

[0003] If the hammer head dipping bag is not treated in time, it will continue to grow larger, which not only hinders the alumina feeding, easily leads to the lack of material in the electrolytic cell and the anode effect, but also causes the shell surface to continue to expand and lead to anodic oxidation, which affects the anode current density. and the anode current distribution

The labor intensity of workers handling hammerhead bags is high, which often leads to a variety of orthopedic occupational diseases
