Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum technology, specifically a novel rotatable shell-breaking mechanism. Background Technology

[0002] The shell-breaking device for electrolytic aluminum cells is a key piece of equipment in the electrolytic aluminum production process. During production, a hard shell layer forms on the surface of the molten electrolyte at approximately 910-970℃ in the electrolytic cell. This shell layer needs to be broken through by the shell-breaking device to allow the addition of alumina raw materials for continued electrolytic production. The shell-breaking device uses a cylinder to control the downward movement of the hammer head, breaking through the hard shell on the electrolyte surface and forming a feeding channel.

[0003] Most existing technologies use hammers and shovels for shell breaking. Hammers have a small striking area, so they are less efficient. Shovels have a large striking area, but they are prone to interference when striking corners. Therefore, whether the rotation of the shovel can be reasonably controlled during the shell breaking process is a problem that needs to be solved. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] like Figures 1 to 8As shown, this utility model discloses a novel rotatable shell-breaking mechanism. The technical solution includes a main body 1, with a reset mechanism 2 and a cylinder 4 on both sides of the main body 1. The reset mechanism 2 includes a cavity 201, with a sliding rod 202 slidably connected inside the cavity 201. A spring 203 is located between the sliding rod 202 and the cavity 201, with both ends of the spring 203 fixed to the sliding rod 202 and the cavity 201 respectively. The output shaft of the cylinder 4 is connected to the sliding rod 202 via a first connecting rod 8. A clamp 5 is located below the main body 1, and the clamp 5 is detachably connected to... The shovel assembly 3 has an intermittent rotation mechanism 6, and a sliding shaft 302 is slidably connected inside the intermittent rotation mechanism 6. The intermittent rotation mechanism 6 includes a housing 601, and a handle 301 is fixedly connected to the top of the housing 601. The handle 301 is detachably connected to the chuck 5. Inside the housing 601 are an upper rotating gear disk 605 and a lower rotating gear disk 604. The upper rotating gear disk 605 has an upper tooth groove 602, and the lower rotating gear disk 604 has a lower tooth groove 603. The upper rotating gear disk 605 and the lower rotating gear disk 604 are mirror images of each other. The sliding shaft 302 is equipped with... A retaining shaft 3021 is provided. When the retaining shaft 3021 moves up and down, it rotates according to the contours of the upper tooth groove 602 and the lower tooth groove 603, thereby intermittently adjusting the angle of the cutter head 303. The retaining shaft 3021 cooperates with the intermittent rotation mechanism 6. A rotating mechanism 7 is located on the sliding shaft 302. The rotating mechanism 7 is fixed to the reset mechanism 2 and the cylinder 4. The rotating mechanism 7 includes an annular groove 701, which is fixedly connected to the sliding shaft 302. Below the annular groove 701 is a lower annular plate 702. A limiting plate 7021 is provided on the upper part, which is located inside the annular groove 701. The annular groove 701 and the limiting plate 7021 contain a pressure bearing 705, which is used to assist the rotation and support of the sliding shaft 302. Above the annular groove 701 is an upper annular plate 703, which is connected to the lower annular plate 702 by a limiting bolt 704. The upper annular plate 703 is not in contact with the annular groove 701. The two sliding rods 202 are connected by a second connecting rod 9, and the second connecting rod 9 is welded to the lower annular plate 702. A cutter head 303 is provided at the bottom of the sliding shaft 302.

[0024] The working principle of this utility model is as follows: In use, this device is installed on a shell-breaking machine. The shell-breaking machine provides reciprocating motion for this device, used for shell breaking and crushing. When the angle of the cutter head 303 needs to be adjusted, the cylinder 4 is activated. The output shaft of the cylinder 4 moves downward, driving the slide rod 202 downward. The second connecting rod 9 on the slide rod 202 drives the sliding shaft 302 downward. The retaining pin 3021 on the sliding shaft 302 moves along the contours of the upper rotating gear plate 605 and the lower rotating gear plate 604 until the retaining pin 3021 falls into the lower tooth groove 603, thus completing the angle adjustment of the cutter head 303. Figure 7As shown, when adjusting the angle again, cylinder 4 moves upward, and the retaining shaft 3021 moves along the contours of the lower rotating gear 604 and the upper rotating gear 605 until the retaining shaft 3021 falls into the upper gear groove 602, thus completing the angle adjustment of the cutter head 303. Figure 8 As shown.
