Description

A variable amplitude slag scavenging device for aluminum electrolysis multifunctional unit

technical field

The invention relates to an aluminum electrolysis slag scavenging device, in particular to a variable amplitude slag scavenging device for an aluminum electrolysis multifunctional unit.

Background technique

The slag removal device is an indispensable device for the electrolytic aluminum multifunctional unit. It is installed on the multifunctional crane.

In the traditional slag fishing device (as shown in Figure 1), the grab is hinged and fixed, and is opened and closed by a link mechanism. The grab only moves in an arc, and the slag cannot be collected in the blind areas on both sides of the bottom of the tank. Unless the slag removal device is lowered to a certain height, although the slag removal can be completed, the grab bucket will damage the cathode at the bottom of the ring tank, causing a furnace leakage accident.

Therefore, there is a special need for a variable amplitude slag scavenging device for an aluminum electrolysis multifunctional unit to solve the above-mentioned existing problems.

Detailed ways

In order to make the technical means, creation features, achievement goals and effects of the present invention easy to understand and understand, the present invention will be further described below with reference to the specific drawings.

Example

As shown in Figure 2, the luffing slag scavenging device of the aluminum electrolysis multifunctional unit of the present invention includes a grab bucket 1, a slider 5, a lever 7 and a cylinder 10. The top of the cylinder 10 is fixed by the cylinder seat 11, and the bottom of the cylinder 10 is fixed A piston rod 9 is connected, the piston rod 9 is connected with the slider 5 through the lever 7, the slider 5 is fixed by the sliding seat 6, the slider 5 is connected with the grab bucket 1 through the first connecting rod 3, and the piston rod 9 is connected through the second The connecting rod 4 is connected with the grab bucket 1 .

In this embodiment, one end of the first link 3 and the slider 5 are hinged to each other, and the other end of the first link 3 and the grab bucket 1 are hinged to each other.

In this embodiment, one end of the second connecting rod 4 is hinged with the piston rod 9, and the other end of the second connecting rod 4 is hinged with the grab bucket 1. When the cylinder 10 moves, it drives the grab bucket 1 to move left and right.

In this embodiment, the middle of the lever 7 is provided with a support base 8 as a lever support. When the cylinder 10 is actuated, the slider 5 is actuated by the lever 7 .

The sliding seat 6 is fixed, the sliding block 5 moves up and down in the sliding seat 6, the connecting rod 3 is respectively connected with the sliding block 5 and the grab bucket 1, and the up and down movement of the sliding block 5 drives the grab bucket 1 to move up and down.

The first connecting rod 3, the second connecting rod 4, the slider 5, the sliding seat 6, the lever 7 and the support seat 8 adopt the connecting rod slider mechanism and the lever principle, so that the grab bucket 1 increases a degree of freedom in the vertical direction, so that the grab The bucket 1 also moves up and down while making the arc movement, and finally the grab bucket 1 moves horizontally to prevent damage to the cathode at the bottom of the tank and avoid the leakage of the furnace.

The working process of the variable amplitude slag scavenging device of the aluminum electrolysis multifunctional unit of the present invention is as follows:

A support base 8 is fixed under the lever 7, the slide block 5 is placed in the slide base 6, one end of the first connecting rod 3 is connected with the slide block 5, and the other end is connected with the grab bucket 1;

When the piston rod 9 moves downward, the lever 7 pushes the slider 5 upward, the first connecting rod 3 lifts the grab bucket 1, and the grab bucket 1 opens;

When the piston rod 9 moves upward, the lever 7 pushes the slider 5 down, and the grab bucket 1 is slowly closed, which not only grabs the electrolytic slag;

Repeat the above actions until the slag removal is completed.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.
