Description

Insulation structure of electrolyzer shelling and aluminum cylinder

technical field

The utility model relates to an insulating structure of a cylinder, in particular to an insulating structure of an electrolytic cell for shelling and aluminum-extracting cylinder.

technical background

The existing cylinder insulation structure on the aluminum electrolytic cell has been widely used in the prebaked anode electrolytic cell for more than 20 years. With the continuous development of the aluminum industry, large-capacity prebaked anode electrolytic cells are continuously developed and applied in production. The existing cylinder insulation method is shown in Figure 1. It has the following technical problems:

1. Inconvenient installation. Existing cylinder 1 is connected with pendulum support 7 earlier when installing, and the positioning holes on the pendulum support 7 and the positioning holes on the insulating backing plate 4 are not easy to align. At the same time, the cumulative manufacturing errors between the positioning holes also exacerbate the occurrence of this situation.

2. Since the insulation of the cylinder 1 is realized by adding an insulating backing plate 4, an insulating washer 6 and an insulating sleeve 5 between the swing shaft support 7 and the supporting angle steel 3, there are many processing parts, time-consuming assembly and high cost.

Utility model content

The technical problem to be solved by the utility model is to provide an insulating structure for the shelling of the electrolytic tank and the aluminum outlet cylinder. The purpose is to effectively solve the installation and insulation performance of the cylinder through structural changes, and reduce the assembly cost and cost.

In order to solve the above-mentioned technical problems, the utility model is realized in the following way: the insulation structure of the electrolytic tank shelling and aluminum outlet cylinder includes a cylinder and a swing shaft bracket. Locate and connect with the pendulum bracket.

The swing shaft of the cylinder is slidingly connected with the insulating bushing.

Advantage and effect of the present utility model are as follows:

The utility model cancels the insulation between the pendulum shaft support and the supporting angle steel structurally, and changes the installation mode of insulation between the pendulum shaft support and the supporting angle steel. The insulating shaft sleeve is installed on the swing shaft bracket, and the purpose of insulating the cylinder is achieved by directly arranging the insulating shaft sleeve on the swing shaft bracket. The insulating structure of the utility model makes it easy to cooperate and install the swing shaft bracket and the supporting angle steel, avoids the phenomenon that the cylinder insulation is easily damaged, and brings convenience to the installation of the cylinder; there are few parts to be manufactured and processed, and the assembly is convenient , Reduce costs and improve installation quality.

Description of drawings

Fig. 1 is a structural schematic diagram of an existing cylinder insulation method.

Fig. 2 is a structural schematic diagram of the cylinder insulation method of the utility model.

In the figure, 1. cylinder; 2. insulating shaft sleeve; 3. supporting angle steel; 4. insulating backing plate; 5. insulating sleeve; 6. insulating washer; 7. pendulum shaft support.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings, and the protection scope of the utility model is not limited by the embodiments.

As shown in FIG. 2 , the insulation structure of the electrolytic tank shelling and aluminum outlet cylinder is provided with an insulating bushing 2 on the swing shaft support 7 , and the cylinder 1 is positioned through the insulating bushing 2 and connected with the swing shaft support 7 . The insulating shaft sleeve 2 is connected on the swing shaft support 7, and the swing shaft of the cylinder 1 slides inside the insulating shaft sleeve 2.

The installation of the present utility model cancels the insulating backing plate 4 between the pendulum bracket 7 and the supporting angle steel 3, cancels the insulation installed between the pendulum bracket 7 and the supporting angle steel 3, cancels the insulating sleeve 5, the insulating Gasket 6.
