Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method and its structure for preventing the bottom of the aluminum electrolytic cell from arching. This method applies a downward force to the bottom of the electrolytic cell to offset the upward arching force of the cell bottom, preventing the electrolytic cell from The upper arch of the bottom not only solves the problem of cathode cracks, but also solves the problem of difficult production and operation, which can prolong the life of the electrolytic cell

Embodiment 1

[0036] Embodiment one: if figure 1 , figure 2 , image 3 and Figure 4 As shown, an anti-arching structure at the bottom of the aluminum electrolytic cell uses a connecting mechanism 14 to connect the cradle 1 of the electrolytic cell with the buttress 13 of the electrolytic cell to prevent the cradle 1 from bending deformation forcibly. This connecting mechanism 14 mainly contains: upper link 4, lower link 9, fork joint 7, steel plate 2, steel plate 3, bolt nut 5, bolt nut 6, bolt nut 8, bolt nut 10, bolt 11 and nut 12.

specific Embodiment approach

[0037] The specific embodiment: weld steel plate 2 on the cradle frame 1 of electrolyzer, open three bolt holes on steel plate 2, connect with another steel plate 3 by bolt nut 5, steel plate 3 is connected with upper link 4 by bolt nut 6, The upper link 4 and the lower link 9 are connected by a fork joint 7. The advantage of using the fork joint 7 is that the upper link 4 and the lower link 9 can not only rotate back and forth, but also can rotate left and right, so that it is convenient for the cradle frame 1 to connect with the electrolytic The connection between the groove buttresses 13 does not produce rigid constraints, and the fork joint 7 and the lower link 9 are connected by bolts and nuts 8 . The lower link 9 is connected with the electrolytic cell support pier 13 through bolts and nuts 10, such as Figure 4 As shown, the bolt nut 10 is composed of a bolt 11 and a nut 12 . The advantage of using bolt connection is that it is convenient for construction and easy to o...

Embodiment 2

[0043] Embodiment two: if Figure 5 , Figure 6 , image 3 and Figure 4 Shown, the connecting mechanism 14 that adopts is identical with embodiment one, and the embodiment of connecting mechanism 14 is also identical, and difference is: this embodiment has adopted two this connecting mechanism 14 on the cradle frame 1 at the bottom of the electrolyzer, Distributed on the cradle frame 1 near the symmetrical center line of the electrolyzer. The steel plate 2 and another steel plate 3 can also be welded; the steel plate 3 and the upper link 4 are welded; the lower link 9 and the electrolytic cell pier 13 are welded; the fork joint 7 and the lower link 9 The connection is welded.

[0044] In this embodiment, an insulating structure is provided at the bolt joints to insulate the cradle frame 1 of the electrolytic cell from the supporting pier 13 of the electrolytic cell. The insulating structure can adopt any structure that can realize insulation, such as insulating gasket or...

Abstract

The invention discloses a method for preventing the bottom of an aluminum electrobath from upwarpping and a structure thereof and in particular relates to a method for preventing the bottom of the aluminum electrobath from upwarpping in the roasting startup process and a structure thereof. The structure comprises: the bottom of the aluminum electrobath is connected with a connecting mechanism (14); one end of the connecting mechanism (14) is connected with a cradle rack (1) on the underside of the aluminum electrobath; and the other end of the connecting mechanism (14) is fixed on a supporting pillar (13) of the electrobath. The method can solve the problem that the bottom of the aluminum electrobath is upwarpped and deformed in the roasting startup process, can prevent producing the crack of cathode and is convenient to produce and operate. The structure has a simple structure, easy realization in operation, obvious effect and wide market prospect.

Description

technical field [0001] The invention relates to a method and structure for preventing the bottom of the aluminum electrolytic cell from arching, in particular to a method and structure for preventing the bottom of the aluminum electrolytic cell from arching during the roasting start-up process. Background technique [0002] With the rapid development of the aluminum electrolysis industry, a series of achievements have been made in the development of large-capacity aluminum electrolysis cells in my country. Large-capacity aluminum electrolysis cells have become the main cell type of the aluminum electrolysis industry. At present, the largest cell type in China is 400kA, and the maximum capacity of series production The electrolytic cell is a 350kA prebaked anode electrolytic cell, and the length of the cell shell is about 18 meters. With the development of large-capacity electrolytic cells, the service life of electrolytic cells has attracted the attention of the aluminum indu...
