Description

Technical Field

[0001] This utility model relates to the field of mechanical design technology, specifically to a transfer and flipping structure device for electrolytic aluminum water. Background Technology

[0002] Electrolytic aluminum production is the process of producing metallic aluminum by electrolyzing molten alumina. It is the core production method of the modern aluminum industry. Bauxite is the main raw material for producing alumina, and its main components are alumina hydrates (such as gibbsite and boehmite). Bauxite reacts with sodium hydroxide solution under high temperature and pressure to produce sodium aluminate solution. Impurities (such as silicon dioxide and iron oxide) form red mud precipitate. After filtering to remove the red mud, carbon dioxide is introduced into the sodium aluminate solution to precipitate aluminum hydroxide. After calcination, alumina with a purity of over 99% is obtained.

[0003] A ladle filled with molten aluminum at high temperature is placed on the platform of the ladle-turning structure, and the molten aluminum is poured into a mixing furnace for mixing. The ladle-turning mechanism has two lifting hydraulic cylinders on both sides of the support platform that receives the ladle. The difference in the lifting angle of the lifting hydraulic cylinders makes the steel plate connected to the hydraulic cylinders easy to tear and be damaged, and also affects the stability of the ladle. At the same time, there is a risk of the molten aluminum ladle tipping over. Therefore, this application is made. Summary of the Invention

[0004] The purpose of this invention is to provide a bag-folding structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The flip-bag structure includes a base, two support frames, two rotating arms, a rotating seat, an aluminum molten ladle, and a hydraulic cylinder. Support frames are provided on both sides of the base. The support frames are rotatably connected to the rotating arms through bearings. The rotating seat is fixed on the rotating arms. The aluminum molten ladle is installed on the rotating seat. The support frames are installed with the rotating arms through a lifting assembly and a balancing assembly.

[0007] The lifting assembly includes universal joint a, hydraulic rod and universal joint b. There are two lifting assemblies, which are respectively set on two support frames. Universal joint a and universal joint b are respectively installed at both ends of the hydraulic rod.

[0008] The balancing assembly includes a balancing frame, support arms, connecting seats, and a balancing plate. The universal joints b of the two sets of lifting assemblies are connected to the balancing frame. The support arm is located at the middle point of the balancing frame. The balancing plate is fixed to the bottom of the two rotating arms. The support arm is rotatably connected to the middle point of the balancing plate through the connecting seats.

[0009] As a further improvement of this utility model, U-shaped bracket a and U-shaped bracket b are respectively installed at both ends of the hydraulic rod.

[0010] As a further embodiment of this utility model: both universal joint a and universal joint b are in the shape of a cross and have four connecting ends. The two symmetrical connecting ends of universal joint a are rotatably connected to the support frame through bearings, and the other two connecting ends of universal joint a are rotatably connected to the U-shaped bracket a through bearings.

[0011] As a further embodiment of this utility model: the two symmetrical connecting ends of the U-shaped bracket b are rotatably connected to the universal joint b through bearings, and the other two connecting ends of the universal joint b are fixedly installed with the U-shaped bracket c, which is fixed to the bottom of the balance frame.

[0012] As a further improvement of this utility model: the balance frame, balance plate and universal joint b are on the same plane, and the rotatable directions of the balance frame, balance plate and universal joint b are the same.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This bag-flipping structure increases the angular flexibility between the hydraulic rod and the support frame through universal joint a, and universal joint b provides angular function between the hydraulic rod and the balance frame. The balance frame adapts to the difference in the lifting angle of the hydraulic rod by tilting, and then transmits the signal to the balance plate through the support arm and connecting seat. The balance plate lifts the rotating arm to realize the bag-flipping action, which solves the problem of unstable bag-flipping and deformation and damage at the connection due to the difference in lifting angle.

Detailed Implementation

[0020] Please see Figures 1-4In this embodiment of the utility model, the flipping structure includes a base 1, two support frames 2, two rotating arms 3, a rotating seat 4, an aluminum molten ladle 5, and a hydraulic cylinder. Support frames 2 are respectively provided on both sides of the base 1. The support frames 2 are rotatably connected to the rotating arms 3 through bearings. The rotating seat 4 is fixed on the rotating arms 3. The aluminum molten ladle 5 is installed on the rotating seat 4. The support frames 2 are installed with the rotating arms 3 through a lifting component 6 and a balancing component 7. In the prior art, the lifting mechanism is directly connected to the hydraulic cylinder. There is a certain difference in the lifting of the hydraulic cylinder. During the lifting process, the difference in the lifting angle makes the steel plate connected to the hydraulic cylinder easy to tear and be damaged. Therefore, this application solves the problem of the difference in lifting angle through the technical improvement of the lifting component 6 and the balancing component 7. The left and right sides of the rotating arms 3 bear the load, maintain the rotation accuracy of the shaft, maintain the flipping action of the aluminum molten ladle 5, and limit its rotation direction.

[0021] The lifting assembly 6 includes a universal joint a605, a hydraulic rod 602, and a universal joint b606. There are two sets of lifting assemblies 6, which are respectively set on two support frames 2. Universal joints a605 and b606 are respectively installed at both ends of the hydraulic rod 602. Universal joints are existing technology, and their core feature is that they can still reliably transmit torque when the included angle of the two shafts changes. In this application, their function is to adapt to the angle changes of the rotating seat 4 and the support frame 2 during the advancement of the hydraulic rod 602.

[0022] The balancing assembly 7 includes a balancing frame 701, a support arm 702, a connecting seat 703, and a balancing plate 704. The universal joints b606 of the two lifting assemblies 6 are connected to the balancing frame 701. The support arm 702 is located at the midpoint of the balancing frame 701. The balancing plate 704 is fixed to the bottom of the two rotating arms 3. The support arm 702 is rotatably connected to the midpoint of the balancing plate 704 via the connecting seat 703. During the pushing process of the hydraulic rods 602, when a lifting angle occurs, the force points of the two hydraulic rods 602 and the balancing frame 701 are at two points, left and right, resulting in a lifting angle deviation. This deviation occurs at the universal joint b606. Under the action of the balance frame 701 and the hydraulic rod 602, the balance frame 701 rotates and tilts. The parallel relationship between the balance frame 701 and the balance plate 704 is broken. However, under the connection between the rotating arm 3 and the support frame 2, the aluminum ladle 5 will not tilt, thus offsetting the lifting angle deviation. The balance frame 701 continues to transmit the upward lifting force to the balance plate 704 through the support arm 702 at the midpoint and the connecting seat 703, so that it still maintains the stable ladle-turning action of the aluminum ladle 5. This solves the problem of unstable ladle-turning and deformation and damage at the connection caused by the difference in lifting angle.

[0023] In a preferred embodiment, the hydraulic rod 602 is equipped with U-shaped brackets a601 and b604 at both ends, and universal joints a605 and b606 are both cross-shaped with four connecting ends. The two symmetrical connecting ends of universal joint a605 are rotatably connected to the support frame 2 through bearings, and the other two connecting ends of universal joint a605 are rotatably connected to the U-shaped bracket a601 through bearings. During the bag-flipping and lifting process, the hydraulic rod 602 needs to adapt not only to the angle change of the bag-flipping action, but also to the tilt angle of the balance frame 701. For this reason, the structure of universal joint a605 is set, which has greater flexibility and adaptability.

[0024] In a preferred embodiment, the two symmetrical connecting ends of the U-shaped bracket b604 are rotatably connected to the universal joint b606 via bearings. The other two connecting ends of the universal joint b606 are fixedly installed to the U-shaped bracket c603, which is fixed to the bottom of the balance frame 701. The universal joint b606 only needs to adapt to the angle change when the balance frame 701 is tilted. Therefore, the other two ends of the universal joint b606 are fixed to the balance frame 701 via the U-shaped bracket c603. The balance frame 701, the balance plate 704, and the universal joint b606 are on the same plane. The rotatable directions of the balance frame 701, the balance plate 704, and the universal joint b606 are consistent. When the balance frame 701 is tilted relative to the balance plate 704 to adapt to the lifting angle difference, the support arm 702 and the connecting seat 703 are required to provide a rotatable connection.
