Detailed Description
The invention is further described with reference to the figures and the specific embodiments.
A traditional aluminum electrolysis multifunctional crown block is shown in fig. 2 and comprises a crown block body 6, a tool trolley 9 (or called a main trolley), an aluminum discharging trolley 8, a crust breaking device 11, a blanking device 10, an electrode changing device 12, a slag fishing device and the like. Wherein, the crust breaking device 11, the blanking device 10, the pole changing device 12, the slag dragging device and the like are all hung on the tool and move along with the tool trolley.
Meanwhile, the upper arm of the crust breaking device 11 is also provided with an air cylinder (for realizing extension) and can operate a lower arm connecting rod to do extension movement. At the end of the lower arm linkage, a cylinder driven metal striker is conventionally mounted to break the shell surface of the alumina (electrolyte) crust prior to pole change.
Example 1: as shown in figure 1, a novel aluminum cell pole-changing non-contact crust breaking device comprises a support 1, a telescopic device 2, a connecting rod 3, a cutting head support 4 and a non-contact cutting head 5, wherein the lower end of the support 1 is hinged with one end of the connecting rod 3, the upper end of the support is fixedly connected to a crown block trolley, the other end of the connecting rod 3 is fixedly connected with the non-contact cutting head 5 and the non-contact cutting head 5 faces, one end of the telescopic device 2 is hinged to the connecting rod 3, and the other end of the telescopic device is hinged. The crust around the anode scrap is cut in a high-temperature cutting mode, so that the anode scrap can be pulled out conveniently, fragments and material slag can not be generated, and the slag fishing process is avoided to the maximum extent.
When the anode of the aluminum electrolytic cell is replaced, the crust around the anode scrap is cut by adopting a non-contact high-temperature cutting mode instead of the traditional direct contact modes such as beating, crushing, sawing and the like. The non-contact cutting head adopts a non-contact working cutting device such as laser, plasma or flame cutting. The non-contact cutting device can be arranged on a crown block to replace the existing crust breaking and slotting device.
