Description
Technical Field
The utility model relates to the technical field of aluminum electrolysis, in particular to an aluminum electrolysis cell crust breaking device.
Background
The blanking system of the aluminum electrolytic cell generally adopts a timing constant-volume blanking device to carry out interval blanking, but the interval blanking has obvious defects. Because the blanking process of the blanking points is a centralized feeding type, alumina is easy to gather near the blanking points, the fluctuation of alumina concentration is large before and after blanking, meanwhile, the existing aluminum electrolytic cell generally adopts a low superheat process route, and a point type blanking system adds a large amount of alumina once, so that the alumina dissolving process is more difficult. Above-mentioned problem can lead to the electrolysis trough heat balance undulant big, and the current efficiency reduces, and the bottom of the furnace pressure drop that can make rise is precipitated to a large amount of aluminium oxide accumulations in the aluminium liquid layer under the feed opening, and the energy consumption increases, and serious person can lead to the furnace deformity to shorten aluminium cell life.
In order to solve the problem of blanking, a domestic prebaked anode electrolytic cell mostly adopts intermediate point type crust breaking blanking, but most of the existing crust breaking hammers do not have a hammer self-cleaning function, so electrolytes can be adhered to the hammers, and a thick 'crust-head bag' is formed on the hammers after cooling. If the treatment is not timely, the blanking at the point is abnormal, and the abnormal effect of the electrolytic cell is caused; in the process of treating the 'shell head bag', the hammer head, the crust breaking cylinder and even the anode inner claw are easily damaged.
The Chinese patent with the publication number of CN2623704Y discloses a crust breaking hammer head, which consists of a hammer head connecting rod (1), a hammer head (5), a sleeve (4) and a sealing and insulating sleeve (2), wherein the sleeve (4) is made of a thick-wall steel pipe, the lower end of the sleeve forms an included angle of 20-60 degrees with the horizontal direction of the hammer head to form a scraping edge, when the hammer head (5) goes upwards and returns to the original position, electrolyte adhered to the hammer head is cleaned by an inclined surface scraping edge of the sleeve (4) fixed on a horizontal cover plate (3) of an electrolytic cell, and the cleaned electrolyte falls into a blanking hole; a sealing and insulating sleeve (2) is arranged between the upper part of the sleeve (4) and the hole of the horizontal cover plate (3), so that the electrolytic flue gas is prevented from overflowing from a gap between the connecting rod (1) and the hole of the horizontal cover plate (3), and the pollution is reduced.
Chinese patent publication No. CN201501933U discloses a crust breaking and blanking processing device for a pre-baked aluminum electrolytic cell, which comprises an outer frame, wherein the outer frame is matched with a blanking gap of the electrolytic cell, and the upper end of the outer frame is fixed with a blanking port at the upper part of the electrolytic cell; the cross section of the outer frame is in a trapezoid shape with a wide upper part and a narrow lower part; the scraping steel nails are uniformly distributed on the inner side of each side wall of the outer frame in a star shape, and the shape of the shell head bag is similar to the shape of the track formed by the end parts of all the scraping steel nails on the two side walls. The device has the advantages of simple structure, simple and convenient operation, easy processing and manufacturing, lower cost, good protection effect and the like, and can protect the anode inner claws close to the left side and the right side of the crust breaking hammer head, reduce the possibility of anodizing iron and prevent the oxidization consumption of the anode inner claws.
Therefore, the raw materials at the blanking point of the blanking system of the aluminum electrolytic cell are easy to gather and slowly dissolve; most of the crust breaking hammers do not have a self-cleaning function and are easy to form a 'crust head bag'. Therefore, there is a need to develop a blanking device which can accelerate the dissolution of the aluminum-silicon solid wastes in the electrolyte and has the shell head self-cleaning function.
