Description

Technical Field

[0001] The utility model belongs to the technical field of recycled aluminum production, and particularly relates to a slag skimming device for separating impurities in aluminum liquid. Background Art

[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and aluminum alloy materials, or aluminum-containing waste. During the manufacturing process, aluminum ingots or scrap aluminum blocks are melted into molten aluminum. This molten aluminum is melted under high-temperature conditions in a large, box-type melting furnace. Because unmelted aluminum ingots or scrap aluminum blocks are typically of lower purity and contain more impurities, some scum will float on the surface of the molten aluminum after it is melted. This scum needs to be skimmed off to prevent the quality of the recycled aluminum. Currently, workers typically use a simple, slender scraper with a scraping plate at the front end to salvage the impurities from the side of the melting furnace. The worker grips the scraper's handle and pushes and pulls it back and forth through the molten aluminum to scrape the impurities to the side of the melting furnace. However, the high temperature inside the melting furnace makes it difficult to manually push and pull the scraper for long periods of time, and the reciprocating push and pull is labor-intensive. Therefore, the existing technology suffers from high labor intensity and low work efficiency. Utility Model Content

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Combined here Figures 1 to 3An embodiment of a slag removal device for separating impurities from molten aluminum will be described below. Specifically, the slag removal device for separating impurities from molten aluminum is constructed as a split structure, comprising a fixed base 100, a first slider 102, a first drive unit, a slide shaft 300, a second slider 302, a first slag removal plate 400, a second drive unit, and a second slag removal plate 600. The first drive unit and the second drive unit cooperate to drive the two first slag removal plates 400 to remove slag from the entire furnace liquid surface and remove the waste slag to the side wall of the furnace near the fixed base 100, thereby improving the efficiency of the slag removal process and reducing labor intensity. In addition, while the first drive unit drives the two first sliders 102 toward each other, the second connecting rod 601 is set, so that the two first sliders 102 simultaneously drive the two second slag removal plates 600 toward each other. The two second slag removal plates 600 further gather the waste slag near the fixed base 100 of the furnace to facilitate subsequent manual discharge of the waste slag.

[0029] Please refer to Figures 1 to 3 , a slag removal device for separating impurities in molten aluminum, comprising a fixing seat 100;

[0030] The fixing base 100 is provided with a first sliding groove 101, in which a pair of symmetrically placed first sliding blocks 102 are slidably engaged. The fixing base 100 is provided with a first driving unit for driving the two first sliding blocks 102 to move closer to or away from each other.

[0031] A horizontally placed sliding shaft 300 is fixed on each of the first sliding blocks 102. A second sliding groove 301 perpendicular to the first sliding groove 101 is formed on each of the sliding shafts 300. A second sliding block 302 is slidably engaged in the second sliding groove 301. A first skiving plate 400 is fixed to the lower end of each of the second sliding blocks 302 via a first connecting rod 401. The first skiving plate 400 is placed parallel to the central axis of the first sliding groove 101. A second driving unit for driving the second sliding block 302 to move along the second sliding groove 301 is provided on each of the sliding shafts 300.

[0032] The lower end of each of the first sliding blocks 102 is fixed with a second scraping plate 600 via a second connecting rod 601. The second scraping plates 600 are located directly below the fixing seat 100. The second scraping plates 600 are placed perpendicular to the central axis of the first chute 101, and the two first scraping plates 400 are located inside the plane where the two second scraping plates 600 are located.

[0033] The fixing base 100 is preferably made of a high-strength, wear-resistant metal alloy or stainless steel. The surface of the fixing base 100 may be sprayed, chrome-plated, etc. to increase corrosion resistance and aesthetics.

[0034] When manufacturing the sliding shaft 300, its straightness and surface finish must be considered to ensure that the second slider 302 moves smoothly thereon. The surface of the sliding shaft 300 may be polished, ground, etc. to reduce friction resistance and improve wear resistance.

[0035] The first slag removal plate 400 and the second slag removal plate are usually made of a special alloy with good high temperature resistance and corrosion resistance to adapt to the working environment in high temperature aluminum liquid.

[0036] Fix the fixing base 100 to the side wall of the furnace opening so that the lower ends of the first and second slag plates 400 and 600 extend below the surface of the molten aluminum. In the initial state, keep the two first slag plates 400 at the end away from the fixing base 100.

[0037] Then, the two second drive units are simultaneously turned on, so that the second drive units drive the second slide block 302, the first connecting rod 401 and the first scraping plate 400 toward the end of the fixed seat 100. The first scraping plate 400 scrapes the waste slag on the liquid surface toward the edge of the furnace near the end of the fixed seat 100. When the first scraping plate 400 approaches the fixed seat 100, the second drive unit drives the second slide block 302 to move in the opposite direction, driving the first scraping plate 400 to return to its original position.

[0038] Then, the first driving unit intermittently drives the two first sliders 102 to move closer to each other, and the first sliders 102 drive the sliding shaft 300, the second driving unit, the second sliders 302, the first connecting rod 401 and the first skimmer plate 400 to adjust their positions.

[0039] The first driving unit cooperates with the second driving unit to drive the two first slag scraping plates 400 to scrape the liquid surface of the entire furnace and scrape the waste slag to the side wall of the furnace near the fixed seat 100, thereby improving the efficiency of the slag scraping and reducing the labor intensity. At the same time, the first driving unit drives the two first sliders 102 to move closer to each other, and the second connecting rod 601 is set, so that the two first sliders 102 synchronously drive the two second slag scraping plates 600 to move closer to each other, and the waste slag near the fixed seat 100 end of the furnace is further gathered by the two second slag scraping plates 600, so as to facilitate the subsequent manual discharge of the waste slag.

[0040] The specific steps for coordinating the first drive unit and the second drive unit are as follows:

[0041] Step 1: After the second driving unit drives the first scraping plate 400 to approach the fixing seat 100, the second driving unit drives the first scraping plate 400 in the reverse direction until it returns to its original position;

[0042] Step 2: After the first skimmer plate 400 moves to the end away from the fixed base 100, the first driving unit drives the two first sliders 102 to move a certain distance toward each other. After moving a certain distance, the first driving unit is turned off and step 1 is repeated.

[0043] The above steps are repeated until the two first scraping plates 400 come into contact with each other, thus completing the scraping work on the entire liquid surface.

[0044] In order to facilitate driving the two first sliders 102 to approach each other, the first driving unit includes a first screw 201 rotatably connected to the first slide groove 101, the first screw 201 and the first slide groove 101 are placed coaxially, the first sliders 102 are threadedly sleeved on the first screw 201, and the screw threads of the first screw 201 on both sides of the symmetry plane of the two first sliders 102 are in opposite directions; by rotating the first screw 201, the two first sliders 102 can be driven to move synchronously, and controlling the rotation direction of the first screw 201 can control the two first sliders 102 to move away from or approach each other.

[0045] The first driving unit also includes a first gear 202 fixedly mounted on either end of the first screw 201, a first rotating motor 203 is mounted on the fixing seat 100, and the output end of the first rotating motor 203 is connected to a second gear 204, and the second gear 204 is engaged with the first gear 202; preferably, the diameter of the second gear 204 is larger than the diameter of the first gear 202, and when the first rotating motor 203 drives the second gear 204 to rotate, the second gear 204 drives the first gear 202 and the first screw 201 to rotate.

[0046] In order to facilitate intermittent control of the rotation of the first screw 201, a toothless groove 2041 is provided on the second gear 204. When the toothless groove 2041 rotates toward the first gear 202, the first gear 202 is separated from the second gear 204; when the toothless groove 2041 rotates toward the first gear 202, the first rotating motor 203 is immediately turned off, and then the second driving unit is turned on to work.

[0047] When the second gear 204 rotates one circle, the moving distance of the first slider 102 is less than or equal to the length of the first slag skimming plate 400 along the axis of the first chute 101, so as to achieve sufficient slag skimming of the furnace liquid surface.

[0048] The second driving unit includes a second screw 501 rotatably connected to the second slide groove 301, the second screw 501 and the second slide groove 301 are placed coaxially, and the second slider 302 is sleeved on the second screw 501 and threadedly connected to the second screw 501; by rotating the second screw 501, the second screw 501 drives the second slider 302 to perform thread transmission, thereby driving the first connecting rod 401 and the first scraper plate 400 to move.

[0049] The second driving unit further includes a second rotary motor 502 fixedly connected to the sliding shaft 300 , and an output end of the second rotary motor 502 is connected to either end of the second screw 501 ; the second rotary motor 502 is turned on to drive the second screw 501 to rotate.
