Description

Technical Field

[0001] This utility model belongs to the field of aluminum processing technology, specifically relating to a slag removal and slag collection device. Background Technology

[0002] When recycling and reusing scrap aluminum and aluminum alloys or aluminum-containing waste, aluminum ingots or scrap aluminum blocks need to be melted into molten aluminum. The melting of molten aluminum takes place under high-temperature conditions in a smelting furnace, which is mostly a cylindrical furnace. During the smelting of aluminum and aluminum alloys, in addition to its own inclusions, aluminum readily reacts with oxygen to form alumina or alumina, resulting in a layer of slag on the surface of the molten aluminum. This slag floats on the surface of the molten aluminum and requires manual slag rakes to continuously collect the slag on the surface of the molten aluminum at the outlet of the smelting furnace. However, the temperature inside the smelting furnace is high, making it difficult for workers to push and pull the rakes for a long time. After the slag has collected, it still needs to be removed from the outlet of the smelting furnace. During this process, workers are prone to accidentally touching the smelting furnace and getting injured. Therefore, the existing technology has the problem of inconvenience in collecting and draining the slag from the surface of the molten aluminum in a cylindrical smelting furnace. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a slag collection device, which solves the problem that it is inconvenient to collect and discharge waste slag from the liquid surface in the cylindrical melting furnace.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A slag collection device, including a fixed frame fixed to the upper part of the smelting furnace;

[0006] The lower end of the fixed frame is equipped with a rotating block located inside the smelting furnace and placed coaxially with the smelting furnace;

[0007] Multiple vertically placed first strips are fixed on the peripheral wall of the rotating block. The multiple first strips are evenly distributed in a ring around the central axis of the rotating block. A second strip is fixed to the lower end of one side of each first strip. The second strip is placed at an angle upward from the side closer to the first strip to the side farther away from the first strip. The uppermost height of the second strip is lower than the uppermost height of the first strip. One end of both the first and second strips is in contact with the peripheral wall of the rotating block. The ends of the first and second strips away from the rotating block are in contact with the inner peripheral wall of the smelting furnace. Multiple filter holes are evenly distributed on both the first and second strips.

[0008] A first telescopic cylinder is mounted on the fixed frame and placed vertically downward. The lower end of the first telescopic cylinder is fixed with a drive unit that is connected to the rotating block. The drive unit is used to drive the rotating block to rotate.

[0009] The principle and effect of the above technical solution are as follows:

[0010] The first telescopic cylinder drives the drive unit and rotating block to adjust the height, so as to adjust the first strip and the second strip to a suitable position according to the height of the aluminum liquid in the melting furnace, so that the upper end of the first strip is above the liquid surface and the second strip is below the liquid surface;

[0011] Then, the drive unit is activated, which drives the rotating block, the first plate, and the second plate to rotate around the central axis of the rotating block. During the rotation, the waste slag floating on the liquid surface is continuously collected on the side of each first plate near the second plate. Then, during the rotation of the first plate, the first telescopic cylinder slowly drives the first plate and the second plate to move upward. When the first plate and the second plate move out of the liquid surface, the aluminum liquid flows out from the filter hole, while the waste slag remains between the first plate and the second plate. This achieves rapid collection of the waste slag floating on the liquid surface and automatically discharges the collected waste slag from the liquid surface for collection, improving the efficiency of slag removal and collection.

[0012] The smelting furnace has an outlet near the upper part of its peripheral wall;

[0013] A second telescopic cylinder is fixed horizontally at the upper end of the circumferential wall of the smelting furnace. Any of the first plates can be rotated to be placed coaxially with the second telescopic cylinder. A vertically downward-placed push plate is fixed to the output end of the second telescopic cylinder through a connector. The push plate is located on the side of the rotating block near the discharge port. One side of the push plate is in contact with the circumferential wall of the rotating block. The lower end of the push plate is parallel to the upper end face of the second plate. The lowest end of the push plate is higher than the lower end face of the discharge hole. The second telescopic cylinder is used to drive the push plate to move closer to or away from the discharge port.

[0014] The drive unit includes a fixed plate fixedly connected to the lower end of the first telescopic cylinder. The lower end of the fixed plate is rotatably connected to a rotating shaft placed coaxially with the rotating block. A first gear is fixedly sleeved on the rotating shaft. A rotating motor is fixedly mounted on the upper end of the fixed plate. The output shaft of the rotating motor passes vertically through the fixed plate and is rotatably connected to the fixed plate. A second gear is fixedly sleeved on the output end of the rotating motor. The second gear meshes with the first gear.

[0015] The number of first slats is N, and the second gear has a missing tooth groove. When the second gear rotates once, the second gear drives the first gear to rotate 1 / N circumference.

[0016] When the second gear separates from the first gear, either of the first slats faces horizontally toward the discharge port;

[0017] A collection box is detachably connected to the outer wall of the smelting furnace near the outlet end. The upper end of the collection box is open, and the upper surface of the collection box is lower than the lower surface of the outlet.

[0018] The lower end of the rotating block has a convex spherical shape.

[0019] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0020] Fixed connection: refers to the process of connecting two separate profiles or parts into a complex part or component using fasteners such as screws, bolts and rivets.

[0021] Detachable connection: Used to connect two or more components or parts, and can be easily disassembled and reconnected.

[0022] The beneficial effects of this utility model are:

[0023] 1. The first telescopic cylinder drives the drive unit and rotating block to adjust the height so as to adjust the first and second plates to the appropriate positions according to the height of the aluminum liquid in the melting furnace, so that the upper end of the first plate is above the liquid surface and the second plate is below the liquid surface;

[0024] The drive unit drives the rotating block, the first plate and the second plate to rotate around the central axis of the rotating block, and in conjunction with the first telescopic cylinder to drive the rotating block to move up and down, so as to quickly collect the floating waste residue on the liquid surface and automatically discharge the collected waste residue from the liquid surface for collection, thereby improving the efficiency of slag removal and slag collection.

[0025] Furthermore, since the second strip is placed at an upward angle, the end of the second strip furthest from the first strip will extend out of the liquid surface first, preventing waste residue from flowing out with the liquid from the end of the second strip furthest from the first strip when the second strip is removed from the liquid surface;

[0026] 2. The coordinated design of the discharge port, the second telescopic cylinder, and the push plate facilitates the timely discharge of waste residue between the first and second slats;

[0027] By using the coordinated arrangement of the first gear, the second gear, the rotating motor, and the missing tooth groove, the rotation angle of the first plate can be precisely controlled each time when discharging the waste residue between the first and second plates, thereby cleaning the corresponding waste residue at each first plate in sequence.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] This combination Figures 1 to 4 This describes an embodiment of a slag removal and slag collection device. Specifically, the slag removal and slag collection device is constructed as a split structure, which includes a fixed frame 100, a rotating block 200, a first slat 201, a second slat 202, a filter hole 203, a first telescopic cylinder 300, and a drive unit. The first telescopic cylinder 300 drives the drive unit and the rotating block 200 to adjust their height, so as to adjust the first slat 201 and the second slat 202 to a suitable position according to the height of the molten aluminum in the melting furnace 700, so that the upper end of the first slat 201 is above the liquid surface and the second slat 202 is below the liquid surface.

[0035] Then, the drive unit is activated, which drives the rotating block 200, the first slat 201, and the second slat 202 to rotate around the central axis of the rotating block 200. During the rotation, the waste slag floating on the liquid surface is continuously collected on the side of each first slat 201 near the second slat 202. Then, during the rotation of the first slat 201, the first telescopic cylinder 300 slowly drives the first slat 201 and the second slat 202 to move upward. When the first slat 201 and the second slat 202 move out of the liquid surface, the aluminum liquid flows out from the filter hole 203, while the waste slag remains between the first slat 201 and the second slat 202. This achieves rapid collection of the waste slag floating on the liquid surface and automatically discharges the collected waste slag from the liquid surface for collection, improving the efficiency of slag removal and collection.

[0036] Please refer to Figures 1 to 4 A slag collection device includes a fixed frame 100 fixed to the upper end of a smelting furnace 700.

[0037] The lower end of the fixed frame 100 is provided with a rotating block 200 located inside the melting furnace 700 and placed on the same axis as the melting furnace 700;

[0038] Multiple vertically placed first strips 201 are fixed on the peripheral wall of the rotating block 200. The multiple first strips 201 are evenly distributed in a ring around the central axis of the rotating block 200. A second strip 202 is fixed to the lower end of one side of each first strip 201. The second strip 202 is placed at an angle upward from the side closer to the first strip 201 to the side away from the first strip 201. The uppermost height of the second strip 202 is lower than the uppermost height of the first strip 201. One end of each first strip 201 and second strip 202 is in contact with the peripheral wall of the rotating block 200. The ends of the first strip 201 and second strip 202 away from the rotating block 200 are in contact with the inner peripheral wall of the smelting furnace 700. Multiple evenly distributed filter holes 203 are opened on each of the first strip 201 and second strip 202.

[0039] A vertically downward-placed first telescopic cylinder 300 is installed on the fixed frame 100. The lower end of the first telescopic cylinder 300 is fixed with a drive unit connected to the rotating block 200. The drive unit is used to drive the rotating block 200 to rotate.

[0040] The first telescopic cylinder 300 drives the drive unit and rotating block 200 to adjust the height so that the first strip 201 and the second strip 202 can be adjusted to a suitable position according to the height of the aluminum liquid in the melting furnace 700, so that the upper end of the first strip 201 is above the liquid surface and the second strip 202 is below the liquid surface.

[0041] Then, the drive unit is activated, which drives the rotating block 200, the first slat 201, and the second slat 202 to rotate around the central axis of the rotating block 200. During the rotation, the waste slag floating on the liquid surface is continuously collected on the side of each first slat 201 near the second slat 202. Then, during the rotation of the first slat 201, the first telescopic cylinder 300 slowly drives the first slat 201 and the second slat 202 to move upward. When the first slat 201 and the second slat 202 move out of the liquid surface, the aluminum liquid flows out from the filter hole 203, while the waste slag remains between the first slat 201 and the second slat 202. This achieves rapid collection of the waste slag floating on the liquid surface and automatically discharges the collected waste slag from the liquid surface for collection, improving the efficiency of slag removal and collection.

[0042] As the first strip 201 is slowly lifted during rotation, the waste residue is still tightly attached to and collected at the second strip 202. Since the second strip 202 is placed at an upward angle, the end of the second strip 202 away from the first strip 201 will extend out of the liquid surface first, preventing the waste residue from flowing out of the end of the second strip 202 away from the first strip 201 along with the liquid when the second strip 202 is removed from the liquid surface.

[0043] When there is a large amount of waste residue, it needs to be collected and processed in multiple stages. In order to facilitate the timely discharge of the waste residue between the first strip 201 and the second strip 202, a discharge port 701 is provided on the periphery of the smelting furnace 700 near the upper end. This facilitates the cleaning and discharge of the waste residue between each first strip 201 and the second strip 202 through the discharge port 701.

[0044] A horizontally placed second telescopic cylinder 400 is fixed to the upper end of the peripheral wall of the smelting furnace 700. Any first plate 201 can be rotated to be placed coaxially with the second telescopic cylinder 400. A vertically downward-placed push plate 401 is fixed to the output end of the second telescopic cylinder 400 through a connector. The push plate 401 is located on the side of the rotating block 200 near the discharge port 701. One side of the push plate 401 is in contact with the peripheral wall of the rotating block 200. The lower end of the push plate 401 is parallel to the upper end face of the second plate 202. The lowermost end of the push plate 401 is higher than the lower end face of the discharge hole. The second telescopic cylinder 400 is used to drive the push plate 401 to move closer to or away from the discharge port 701.

[0045] When a large amount of waste residue accumulates at any of the first slats 201, the first telescopic cylinder 300 is activated to lift the first slat 201 and the second slat 202. The first slat 201 is then rotated to be placed coaxially with the first telescopic cylinder 300 and horizontally facing the discharge outlet 701. The first slat 201 and the second slat 202 are then lifted again by the first telescopic cylinder 300 until the lower end of the push plate 401 is in contact with the lower end of the second slat 202. Finally, the second telescopic cylinder 400 is activated to drive the push plate 401, automatically discharging the waste residue between the first slat 201 and the second slat 202 from the discharge outlet 701.

[0046] The drive unit includes a fixed plate 501 fixed to the lower end of the first telescopic cylinder 300. The lower end of the fixed plate 501 is rotatably connected to a rotating shaft 502 placed coaxially with the rotating block 200. A first gear 503 is fixedly sleeved on the rotating shaft 502. A rotating motor 504 is fixedly fixed to the upper end of the fixed plate 501. The output shaft of the rotating motor 504 passes vertically through the fixed plate 501 and is rotatably connected to the fixed plate 501. A second gear 505 is fixedly sleeved at the output end of the rotating motor 504. The second gear 505 meshes with the first gear 503. When the rotating motor 504 is turned on, it drives the second gear 505, which in turn drives the first gear 503, the rotating shaft 502, and the rotating block 200 to rotate.

[0047] The number of first slats 201 is N. The second gear 505 has a toothed groove. When the second gear 505 rotates once, the second gear 505 drives the first gear 503 to rotate 1 / N circumference.

[0048] When the second gear 505 separates from the first gear 503, either of the first strips 201 is horizontally oriented toward the outlet 701;

[0049] When it is necessary to discharge the waste residue on each of the first slats 201 in sequence, after the waste residue between any first slat 201 and the corresponding second slat 202 is discharged, the first telescopic cylinder 300 is activated to drive the first slat 201 and the second slat 202 to move downwards. Then, the drive unit is activated to drive the rotating block 200 to rotate, so that the other first slat 201 moves horizontally toward the discharge outlet 701. Through the opening of the missing tooth groove on the second gear 505, when the second gear 505 separates from the first gear 503, the rotating motor 504 is immediately turned off, so as to accurately control the rotation angle of the first slat 201, and then clean the corresponding waste residue at each of the first slats 201 in sequence.

[0050] A collection box 600 is detachably connected to the outer wall of the smelting furnace 700 near the discharge port 701. The upper end of the collection box 600 is open, and the upper surface of the collection box 600 is lower than the lower surface of the discharge port 701. This is to collect and treat the waste slag discharged from the discharge port 701. Preferably, the detachable connection between the two can be achieved by bolt connection.

[0051] The lower end of the rotating block 200 is a raised spherical shape to prevent waste residue from remaining at the lower end of the rotating block 200.
