Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum electrolysis, and more specifically, to a device for preventing anodic oxidation at the material feeding point in aluminum electrolysis production. Background Art
[0002] The 500KA series electrolytic cells are large electrolytic cells with relatively advanced production technology and stable production at present. In aluminum electrolysis production, the anode is an essential raw material and belongs to consumables. When the operator seals the anode, the anode must be completely covered with the face shell block. If part of the anode is exposed, it will accelerate the consumption of the anode, greatly reduce the service life of the anode, increase the production cost, and at the same time, if the replacement is not timely, it may also cause an increase in the iron content in the primary aluminum, affecting the production and the quality of the aluminum liquid.
[0003] The 500KA series electrolytic cells involve seven-point or six-point material feeding. Each material feeding point is adjacent to four anodes. When replacing each group of anodes, the anodes adjacent to the material feeding point will be exposed, including the newly installed anodes. At this time, the front four anodes and the middle seam need to be blocked to seal the anode. At present, the manual sealing of the anode takes a long time, has a large labor intensity, and is not tightly sealed, resulting in anodic oxidation. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a device for preventing anodic oxidation at the material feeding point in aluminum electrolysis production, which can prevent anodic oxidation, extend the service life of the anode, ensure the quality of the primary aluminum, reduce the production cost, and reduce the labor intensity.
[0005] The embodiments of the utility model are realized through the following technical solutions:
[0006] A device for preventing anodic oxidation at the material feeding point in aluminum electrolysis production includes a main body. One end of the main body is connected with a handle, the other end of the main body is connected with a baffle, and a support is also connected to the main body. The support and the baffle are located on the same side of the main body. The baffle includes a support plate I and a support plate II, and the included angle between the support plate I and the support plate II is 120°.
[0007] Furthermore, the support plate I and the support plate II have the same shape, both being right-angled trapezoids. The lower base of the support plate I is connected to the main body, the right-angled side of the support plate II is connected to the right-angled side of the support plate I, and the lower base of the support plate II and the lower base of the support plate I are located on the same horizontal plane.
[0008] Furthermore, the support includes a support rod I and a support rod II, and the support rod I and the support rod II are connected to form an inverted V shape.
[0009] Furthermore, the distance between the bottoms of the support rod I and the support rod II is 0.3 - 0.5m.
[0010] Further, the bracket further includes a sliding sleeve sleeved on the main body, and the first support rod and the second support rod are respectively connected to the sliding sleeve.
[0011] Further, the handle is an oval ring.
[0012] Further, the main body, the handle, the baffle and the bracket are all made of stainless steel.
[0013] The technical solution of the embodiment of the present utility model has at least the following advantages and beneficial effects:
[0014] In the present utility model, the main body connects the baffle, the bracket and the handle into a whole. When in use, the baffle selects the entering direction according to the direction of the blanking point, and adjusts the baffle to the best position suitable for the blanking point according to the distance between the blanking pipe and the hammer head and the size of the blanking tuyere. The design of the first support plate and the second support plate to form the baffle is because a single baffle cannot well block the electrolyte from leaking to the tuyere to block the blanking point during the casting of the anode (middle seam and front and rear poles). The connection of the two support plates can completely seal the anode, well protect the anode from oxidation and will not cause the blanking point to be blocked. And at the same time, two directions are blocked, saving time for the operator and reducing labor intensity. The first support plate and the second support plate are at 120°, mainly to prevent the blanking point from being too small and causing blockage. The handle can keep the whole device stable and easy to take out, and will not affect the operation due to the weight of the baffle. The bracket can play a fulcrum role and facilitate the taking and placing of the baffle. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment
[0026] Such as Figures 1-3As shown in the figure, this embodiment provides a device for preventing anode oxidation at the material feeding point in aluminum electrolysis production, including a main body 1. One end of the main body 1 is connected with a handle 2, and the other end of the main body 1 is connected with a baffle 3. A bracket 4 is also connected to the main body 1. The bracket 4 and the baffle 3 are located on the same side of the main body 1. The baffle 3 includes a support plate I 31 and a support plate II 32, and the included angle between the support plate I 31 and the support plate II 32 is 120°.
[0027] The main body 1 connects the baffle 3, the bracket 4 and the handle 2 into a whole. When using the baffle 3, select the entry direction of the baffle 3 according to the direction of the material feeding point. According to the distance between the material feeding pipe and the hammer head and the size of the material feeding fire hole, adjust the baffle 3 to the best position suitable for the material feeding point and then it can be used. The design of the support plate I 31 and the support plate II 32 to form the baffle 3 is because a single baffle 3 cannot well block the electrolyte from leaking to the fire hole when casting the anode (the middle seam and the front and rear poles), which will easily block the material feeding point. However, the connection of two support plates can completely seal the anode, well protect the anode from oxidation and will not cause the material feeding point to be blocked. And it seals two directions at the same time, saving time for the operator and reducing labor intensity. The included angle between the support plate I 31 and the support plate II 32 is 120°, mainly to prevent blockage of materials due to too small a material feeding point. The handle 2 can keep the whole device stable and easy to take out, and will not affect the operation due to the weight of the baffle 3. The bracket 4 can play a role of a fulcrum, facilitating the taking and placing of the baffle 3. Preferably, the total length of the main body 1 is 2.8 m. The total length design is based on the distance from the material feeding point of the 500 KA electrolytic cell type to the cell shell, and also refers to the distance from the column busbar to the cell. It should not be too long, otherwise it will be difficult to take out at the column busbar, and if it is too short, there will be no safe distance between the operator and the cell.
[0028] In this embodiment, the support plate I 31 and the support plate II 32 have the same shape, both are right trapezoids. The lower bottom of the support plate I 31 is connected to the main body 1, the right-angle side of the support plate II 32 is connected to the right-angle side of the support plate I 31, and the lower bottom of the support plate II 32 and the lower bottom of the support plate I 31 are on the same horizontal plane. At this time, the support plate I 31 and the support plate II 32 form a shape with a large upper opening and a small lower opening, which is easy to take out after casting and is convenient for inserting the baffle 3 into the material feeding point. Preferably, the lengths of the right-angle sides are 0.3 m in length and 0.15 m in short width, and the height is 0.4 m.
[0029] In this embodiment, the bracket 4 includes a support rod I 41 and a support rod II 42, and the support rod I 41 and the support rod II 42 form an inverted V shape after connection. It can form a triangular structure when in use, improving the stability of the bracket 4. It plays a role of a fulcrum when in use. Holding the handle 2, the distance between the baffle 3 and the hammer head can be adjusted, and the baffle 3 can be adjusted to the best position suitable for the material feeding point. The baffle 3 has a fulcrum and is easy to place and take out.
[0030] In this embodiment, the distance between the bottom of the first support rod 41 and the bottom of the second support rod 42 is 0.3 - 0.5 m. Preferably, the lengths of both the first support rod 41 and the second support rod 42 are 0.3 m. In this way, the first support rod 41 and the second support rod 42 can form a triangular structure during support, improving the stability of the bracket 4.
[0031] In this embodiment, the bracket 4 further includes a sliding sleeve 43. The sliding sleeve 43 is sleeved on the main rod 1, and the first support rod 41 and the second support rod 42 are respectively connected to the sliding sleeve 43. By means of the sliding sleeve 43, the fulcrum position of the bracket 4 can be adjusted, improving the supporting effect on the main rod 1 and the baffle 3.
[0032] In this embodiment, the handle 2 is an oval ring. Preferably, the diameter of the oval ring is 0.1 - 0.2 m. The oval design is for facilitating the stable direction. When not in use, it can be hung on the tool rack. The handle 2 controls the direction, facilitating the adjustment of the position of the baffle 3. When the baffle 3 is inserted into the feeding point or taken out during use, the whole device can be kept stable and easy to take, without being affected by the weight of the baffle 3 during operation. The arc design is convenient for hanging on the tool rack to maintain the 6S management of the site after use. The size of the handle 2 can be changed according to the size of the actual user's hand.
[0033] In this embodiment, the main rod 1, the handle 2, the baffle 3 and the bracket 4 are all made of stainless steel. The selected material is stainless steel, which is light in weight and convenient for handling, and can eliminate the influence of the magnetic field, improving the safety guarantee.
[0034] The working principle of a device for preventing the anodic oxidation at the feeding point in aluminum electrolysis production is as follows: After the anode is replaced, according to the orientation between the feeding point and the anode, hold the handle 2 with one hand, and adjust the distance between the baffle 3 and the anode to be about 2 cm according to the size of the feeding point. Pour the broken materials and electrolyte, and after cooling for two or three minutes, pull the handle 2 outwards to take it out.
[0035] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, various modifications and changes can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
