Description

Technical Field

[0001] The utility model belongs to the technical field of waste aluminum recovery and relates to a foam scraping device for aluminum ingot casting. Background Art

[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and scrap aluminum alloy materials or aluminum-containing waste. It is an important source of metallic aluminum. Recycled aluminum mainly appears in the form of aluminum alloy. Because recycled aluminum has many advantages such as short process and low energy consumption, it has good ecological and social benefits.

[0003] After the recycled aluminum waste is screened, crushed and melted, a part of it needs to be poured into a mold to form aluminum ingots for easy transportation and reproduction. After pouring, foam will appear above the molten aluminum. At this time, the operator needs to use a scraper to scrape off the foam on the top. However, after repeated use, the scraped foam and molten aluminum will stick to the scraper, making it inconvenient to recycle the mixture of foam and molten aluminum.

[0004] Based on this, we designed a foam scraping device for aluminum ingot casting. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a foam scraping device for aluminum ingot casting. The technical problem to be solved by the utility model is: how to centrally collect the foam mixture scraped off during aluminum ingot casting for convenient recycling.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A foam scraping device for casting aluminum ingots comprises a base plate and a scraper, wheels are arranged on both sides of the base plate, a truck bed is arranged above the base plate, a connecting rod is arranged below the truck bed, two symmetrically distributed bearing seats are fixed on the base plate, and the two ends of the connecting rod are rotatably arranged in the bearing seats at corresponding positions respectively, grooves are opened on both sides above the truck bed, the scraper comprises a thin plate, a surrounding plate is arranged at the edge of the thin plate, two symmetrically distributed hand-held rods are fixed on the surrounding plate, and the hand-held rods are placed in the grooves, and the outer sides of the hand-held rods are provided with heat insulation sleeves.

[0008] A first graphite heating plate is fixed to the lower surface of the truck bed, a first switch is installed at the rear of the truck bed, a connecting block is fixed to the bottom of the truck bed, and two elastic electric contacts are fixed to the lower surface of the connecting block, the elastic electric contact, the first switch and the first graphite heating plate are connected in series, a battery box for storing batteries is arranged on the bottom plate, and a connector is arranged at the side end of the battery box, and two electric contacts are arranged on the connector.

[0009] With the above structure, when the truck bed is flattened, the elastic electric contact piece contacts the electric contact block at the corresponding position during use, and transmits electricity to the series circuit of the elastic electric contact piece, the first switch and the first graphite heating plate. When a large amount of scum and molten aluminum mixture accumulates in the truck bed, it needs to be dumped. At this time, the first switch can be turned on to heat the first graphite heating plate to melt the solidified molten aluminum at the bottom of the truck bed again, thereby preventing the scum and aluminum mixture from sticking to the truck bed.

[0010] A first pad is fixed to the front end of the bottom of the bucket, and two symmetrically distributed second pads are fixed to the rear end of the bottom of the bucket.

[0011] With the above structure, the first pad can prevent the first graphite heating plate from colliding with the bottom plate when the truck bed tilts forward and dumps, thereby protecting the first graphite heating plate. Similarly, the second pad can protect the first graphite heating plate when the truck bed is laid flat.

[0012] A second graphite heating plate is fixed inside the truck bed and is in contact with the thin plate. A second switch is fixed behind the truck bed and is connected in series with the second graphite heating plate, and the second graphite heating plate is connected in parallel with the first graphite heating plate.

[0013] With the above structure, when in use, when foam and aluminum water solidify and adhere to the thin plate, the operator can turn on the second switch to make the second graphite heating plate heat up. After the scraper has scraped once or several times, it can be placed in the groove, and the thin plate is heated by the second graphite heating plate, so that the solidified aluminum water and foam melt and fall into the truck bucket, which is convenient for the subsequent use of the scraper.

[0014] Fixed rods are fixed on both sides of the bucket, two symmetrically distributed mounting seats are fixed on the bottom plate, and electric push rods are hinged on the mounting seats, and the other end of the electric push rod is hinged to the fixed rod at the corresponding position.

[0015] With the above structure, when the bucket needs to be tilted, the electric push rod can be extended to drive the bucket to rotate along the connecting rod to pour out the mixture of floating foam and molten aluminum inside, without manual dumping, to prevent operators from being scalded.

[0016] Compared with the prior art, the foam scraping device for aluminum ingot casting has the following advantages:

[0017] 1. Through the truck bucket, connecting rod, groove and scraper, the scraped foam and aluminum water can be collected in the truck bucket for centralized treatment. The scraper can be placed in two grooves, which is more convenient to use.

[0018] 2. Through the first graphite heating plate, when the bucket is dumped, the solidified aluminum water at the bottom of the bucket is melted again to prevent the mixture of foam and aluminum from sticking to the bucket. Through the second graphite heating plate, when the foam and aluminum water solidify and stick to the thin plate, the thin plate is heated to make the solidified aluminum water and foam melt and fall into the bucket, which is convenient for the subsequent use of the scraper.

[0019] 3. When the truck bed needs to be tilted, the electric push rod can be extended to drive the truck bed to rotate along the connecting rod to pour out the mixture of floating foam and molten aluminum inside. Manual dumping is not required to prevent operators from being scalded. BRIEF DESCRIPTION OF THE DRAWINGS
