Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum production, in particular to a tipping structure for vacuum ladle lifting. Background Art

[0002] In recent years, the electrolytic aluminum industry has developed rapidly. Large prebaked electrolytic cells with a current intensity of 500KA have become the main cell type in the current electrolytic aluminum industry. In order to adapt to this cell type and improve the efficiency of aluminum tapping, the matching vacuum ladle for aluminum tapping has become increasingly large-scale, and higher requirements have been placed on the efficiency and quality of vacuum ladle cleaning.

[0003] The traditional method of manually cleaning the vacuum bag is to first open the lid of the vacuum bag, and after it cools to room temperature, the worker enters the vacuum bag and uses a pneumatic pick to scrape off the aluminum slag and electrolyte on the inner wall. The entire operation process is labor-intensive and inefficient, and the actual work quality is also poor. Utility Model Content

Two of the four triangular brackets form a group, and each group of two triangular brackets are inclined toward the central axis direction of the blocking plate. When the vacuum ladle is tipped over, the edge of the vacuum ladle in the inclined direction contacts the rollers, and the vacuum ladle is stuck, thereby improving stability.

[0007] Preferably, two retaining plates are provided at the top of the load-bearing base, and two long grooves are formed through the top of the load-bearing base at the bottom of the retaining plates. A Y-shaped bracket is provided at the top of the heavy base at the front end of the long grooves. The two retaining plates are limited by the long grooves for linear movement, which is convenient for fixing the bottom of vacuum bags of different sizes, and the Y-shaped bracket supports the output pipe of the vacuum bag.

[0008] Preferably, the bottom ends of the two positioning plates pass through long grooves through columns, and the columns arranged at the bottom ends of the positioning plates extend from top to bottom to form a load-bearing base. An adjustment plate is arranged at the extended end of the column, and a screw is arranged through one side of the two adjustment plates. The two screws are arranged opposite to each other and connected at the ends. When the screw rotates, the two adjustment plates are driven to perform relative linear motion, so that the distance between the positioning plates increases or decreases, which is convenient for fixing the bottom of vacuum lifting bags of different sizes.

[0009] Preferably, the outer surfaces of the two screws on the outer side of the adjustment plate are provided with support bearings, and the top ends of the support bearings are jointly installed on the bottom end of the base.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The vacuum ladle has a tilting structure with two hydraulic rods. When the two hydraulic rods are running, the telescopic ends of the hydraulic rods extend to push the outer expansion block to flip upward, so that the load-bearing base flips and drives the vacuum ladle to tilt. The structure is stable and the vacuum ladle can be tilted to a certain angle, which is convenient for the automated tool to reach into the interior of the ladle to clean the vacuum ladle and improve production efficiency.

[0013] 2. The vacuum ladle has a tilting structure. The two adjustment plates are driven by the screw to perform relative linear motion, so that the distance between the positioning plates is increased. Then the vacuum ladle is moved to the top of the load-bearing base, and the turntable is rotated in the opposite direction to reduce the distance between the positioning plates, and the bottom of the vacuum ladle is clamped. Then the turntable is rotated in the opposite direction to reduce the distance between the positioning plates, and the bottom of the vacuum ladle is clamped, so that the vacuum ladle is more stable when it is tilted, and it is convenient to fix vacuum ladle of different sizes, and it has a wide range of applications.
