Description

Technical Field

[0001] This utility model belongs to the field of aluminum electrolysis cell outlet casting technology, specifically relating to a device for casting aluminum at the outlet of an aluminum electrolysis cell. Background Technology

[0002] In the daily production and maintenance of aluminum electrolytic cells, the casting and maintenance of the aluminum outlet is a crucial task. The traditional method involves using tools such as shovels, small and large ladles for casting, shaping the outlet with the shovel, and then pouring electrolyte to complete the shaping. This traditional approach has many drawbacks: firstly, it requires multiple tools; secondly, the cast aluminum outlet is prone to detachment; thirdly, the resulting outlets are inconsistent in shape and size; and fourthly, the outlet is easily damaged during electrolyte transfer and aluminum extraction. Due to these shortcomings, the constructed aluminum outlets are of inconsistent specifications, unstable, and easily damaged. The anode at the outlet is also prone to oxidation, resulting in high heat dissipation at the outlet location, causing numerous adverse effects on the electrolytic cell. Therefore, improvements through technological innovation and innovative tools are necessary. Utility Model Content

[0003] The purpose of this invention is to provide a device for casting aluminum at the outlet of an aluminum electrolysis cell, so as to solve the problem that the lack of molds affects the casting process in traditional aluminum outlet casting.

[0004] The technical solution of this utility model is: a device for casting aluminum at the outlet of an aluminum electrolysis cell, including a mold, the mold including two side plates, an arc plate connected between one end of the two side plates, the two side plates and the arc plate forming a U-shaped opening structure in the plane, a crossbar connected to the other end of the two side plates respectively, the two crossbars being connected by a first fixing rod, a wheel frame provided below the connection between the first fixing rod and the crossbar, and a wheel provided on the wheel frame.

[0005] As a further improvement of this utility model, a second fixed rod is connected between the two crossbars, and a sleeve is movably sleeved on the second fixed rod, with a support frame connected to the sleeve.

[0006] As a further improvement of this utility model, a handle is connected to the end of the crossbar that is opposite to the mold, and the horizontal connection angle α between the handle and the crossbar is 130°-140°.

[0007] As a further improvement of this utility model, the side plate has a right-angled trapezoidal cross section, the height of the trapezoid is horizontally connected to the crossbar, and the angle β between the hypotenuse of the trapezoid and the crossbar is 160°-170°.

[0008] The beneficial effects of this utility model are as follows: The device is easy to install, requiring only one person to complete the shaping of the aluminum outlet of the aluminum electrolysis cell. Wheels facilitate movement, and handles help correct direction and assist movement. Lowering the support frame ensures stability during operation. The first and second fixed frames maintain the device's stability. The mold's cross-section is a right-angled trapezoidal shape at a certain angle, facilitating adjustment to lock the mold into place at the aluminum outlet. Aluminum outlet construction can be performed without special assistance, significantly improving the efficiency of aluminum outlet casting, reducing labor intensity, and making demolding after casting easier, further increasing work efficiency.

[0009] This utility model has a long service life and can ensure the uniformity of the shape of the aluminum outlet casting. It provides a simple and easy-to-use mold for the standardized construction of the aluminum outlet of the electrolytic cell in the electrolytic aluminum production process. It can effectively solve the problems of labor-intensive, labor-intensive and unstable construction in the aluminum outlet construction process, ensure the uniformity of the aluminum outlet specifications of the entire electrolytic series, and reduce the labor intensity of workers.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1-3As shown, an apparatus for casting aluminum at the outlet of an aluminum electrolysis cell includes a mold 1. The mold 1 includes two side plates 11. An arc plate 12 is connected between one end of the two side plates 11. The two side plates 11 and the arc plate 12 form a U-shaped opening structure in the plane. The other ends of the two side plates 11 are respectively connected to crossbars 2. The two crossbars 2 are connected by a first fixing rod 51. A wheel frame 4 is provided below the connection between the first fixing rod 51 and the crossbar 2. A wheel 6 is provided on the wheel frame 4.

[0015] A second fixed rod 52 is connected between the two crossbars 2. A sleeve 53 is movably fitted on the second fixed rod 52, and a support frame 3 is connected to the sleeve 53. A handle 7 is connected to the end of the crossbar 2 that is opposite to the mold 1. The horizontal connection angle α between the handle 7 and the crossbar 2 is 130°-140°. The side plate 11 has a right trapezoidal cross section. The height of the trapezoid is horizontally connected to the crossbar 2, and the angle β between the hypotenuse of the trapezoid and the crossbar 2 is 160°-170°.

[0016] Example 1 Mold 1 is made of 8mm iron plate or other materials with good heat resistance. Mold 1 consists of two side plates 11 and an arc plate 12, forming a U-shaped structure with a large opening and a small closing end. The outer circumference of mold 1 is adapted to the shape of the aluminum outlet 9 to be poured. The arc plate 12 at the front end of mold 1 has a diameter of φ=90mm, and mold 1 is U-shaped and gradually widens from the inside to the outside, with a width of ≤350mm. The cross-sectional shape of the side plate 11 of mold 1 is a right trapezoid. The height of the trapezoid is connected horizontally to the cross bar 2 in a straight line. The angle β between the hypotenuse of the trapezoid and the cross bar 2 is 165°. The angle α between the handle 7 and the cross bar 2 is 135°. If the pouring position is lower than the worker's standing position, the placement angle of mold 1 can be adjusted to lock it with the aluminum outlet 9, thereby ensuring coordination during use.

[0017] The mold 1 is welded to the crossbar 2, making it easy to replace. The welded parts can be cut off and the mold 1 replaced by oxy-acetylene welding, ensuring the lowest cost. The first fixed frame 51 and the second fixed frame 52 are welded from ordinary welded pipes, which can prevent the mold 1 body from deforming when heated, and enhance its heat creep resistance and strength. When the support frame 3 is not in use, the sleeve 53 is rotated to allow the support frame 3 to be placed on the first fixed frame 51, which will not affect the normal movement of the device, nor will it occupy space, making it convenient to use. Wheels 6 are respectively set on both sides of the bottom of the wheel frame 4, which facilitates the movement of the device and also improves stability.

[0018] like Figure 4As shown, when using the device, open the electrolytic cell door and push the device to insert the mold 1 into the aluminum outlet 9. The bottom of the mold 1 rests on the electrolyte crust 8, which is 10-15cm away from the pressure iron. Adjust the angle of the mold 1 to lock it in place with the aluminum outlet 9. Rotate the sleeve 53 to drive the support frame 3 to support it on the concrete floor 10, ensuring that the device and the mold 1 do not fall over or tilt. Then, use a shovel to fill the gap between the mold 1 and the aluminum outlet 9 with the prepared broken pieces. Then, use an oxide scoop or a large ladle to scoop several spoonfuls of electrolyte solution through the mold 1 and pour them onto the broken pieces. Finally, cover the broken pieces with about 3cm of alumina powder. Slightly shake the crossbar 2 until the mold 1 separates from the solidified electrolyte. Then, lift the mold 1 and remove the device for future use.
