Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot casting, and in particular to a slag removal device for an aluminum molten furnace. Background Technology

[0002] Aluminum ingot casting companies use molten aluminum as raw material and process it with casting machines to obtain large-sized aluminum ingots.

[0003] The company uses a furnace to obtain molten aluminum. Various recycled materials are fed into the furnace and melted by heating. The molten aluminum obtained in the furnace needs to be manually stirred to ensure that the composition of the molten aluminum is uniform. In addition, the slag that forms on the surface of the molten aluminum also needs to be separated.

[0004] Currently, molten aluminum is stirred manually using a slag-skimming rod with a slag-skimming plate at the head. The slag is skimmed from the plate to the furnace threshold, where it is carried away by the inclined surface. The mixed molten aluminum flows back into the furnace via the inclined surface. Due to the high temperature around the furnace door, the slag-skimming rod is designed to be quite long, requiring several people to work together to perform the slag-skimming operation. This results in high labor intensity and low efficiency.

[0005] Therefore, designing a convenient, labor-saving, and highly efficient slag removal device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a slag removal device for an aluminum molten furnace. This device has a simple structure, low processing cost, can significantly reduce manual labor intensity, and improve slag removal and stirring efficiency.

[0007] The technical solution of this utility model is: a slag removal device for an aluminum molten furnace, including a forklift and a slag removal rod. The head end of the slag removal rod is provided with a slag removal plate, and the tail end of the slag removal rod is provided with an insertion part. The height of the insertion part is higher than the height of the slag removal plate. The slag removal rod is detachably mounted on the fork arm of the forklift through the insertion part, and the combination constitutes the slag removal device for the aluminum molten furnace.

[0008] The insertion part includes a base plate and insertion cylinders fixed on both sides of the base plate. Multiple insertion plates are arranged at intervals along the length direction of the insertion cylinders on the base plate between the two insertion cylinders. The tail end of the slag scraper passes through the multiple insertion plates and is locked in position.

[0009] The insert has a rectangular cross-section and is welded to both sides of the bottom surface of the substrate.

[0010] The slag-removing rod is provided with a limiting block, and the tail end of the slag-removing rod is provided with a limiting hole that runs vertically through the radial direction. The tail end of the slag-removing rod passes through multiple insert plates. The limiting block cooperates with the insert plate located at the head to form an axial limit. The tail end of the slag-removing rod passes through the insert plate located at the tail end and passes through the limiting hole through the limiting pin to form an axial limit.

[0011] The number of insert plates is three, which are fixed to the top of the base plate by welding. Each end of the three insert plates is provided with a reinforcing plate, and the reinforcing plate is welded to the base plate and the insert plates.

[0012] The slag removal plate is composed of an upper trapezoidal plate and a lower rectangular block.

[0013] The head of the slag-scraping rod is welded to the trapezoidal plate, and a reinforcing rib is provided between the slag-scraping rod and the trapezoidal plate.

[0014] The above technical solution has the following beneficial effects: 1. The slag removal device for the aluminum molten furnace includes a forklift and a slag removal rod. The slag removal rod is used to stir the aluminum molten furnace and remove floating slag. The forklift is used to drive the slag removal rod to achieve the purpose of stirring and removing slag, which significantly reduces the intensity of manual labor. The slag-removing rod has a slag-removing plate at its head and an insertion part at its tail, with the insertion part being higher than the slag-removing plate. The slag-removing rod is detachably mounted on the forklift's fork arm via the insertion part, forming a slag-removing device for an aluminum molten furnace. The slag-removing rod is usually placed on the factory ground. When the forklift moves, the fork arm is controlled to insert into the insertion part at the tail end of the slag-removing rod, and the fork arm is raised, making the height of the slag-removing rod adjustable. Because the slag-removing plate at the head of the slag-removing rod is suspended, it creates a large torque on the insertion part at the tail end, resulting in greater friction between the insertion part and the fork arm. No specific limiting mechanism is needed to maintain the position of the insertion part on the fork arm. When the slag-removing rod is supported on the factory ground, the torque and friction disappear simultaneously, and the forklift can be separated from the slag-removing rod, improving the utilization rate of the forklift. Forklift operators control the forklift and fork arm movements, allowing the slag-scraping plate of the slag-scraping rod to enter the furnace through the furnace door. By controlling the forklift's forward and backward movements, and adjusting the height of the fork arm, the slag-scraping plate is controlled to scrape the floating slag to the furnace threshold. With manual assistance or continued control of the forklift and fork arm movements, the slag can be scraped out of the furnace along the inclined surface of the furnace threshold. The entrained molten aluminum, under the influence of gravity, flows back into the furnace along the inclined surface of the furnace threshold, reducing aluminum loss and ensuring on-site safety. Because the height of the slag-scraping plate is lower than the height of the insertion part, controlling the height of the fork arm allows the lower part of the slag-scraping plate to be submerged in the molten aluminum. Controlling the forklift's forward and backward movement, and coordinating with the rotation direction, changes the orientation of the fork arm, causing the slag-scraping plate at the head of the slag-scraping rod to swing with a greater amplitude, thus agitating the molten aluminum. Since both slag scraping and agitation can be achieved by operating the fork arm, the intensity of manual labor is greatly reduced, and work efficiency is improved.

[0015] 2. A limiting block is provided on the slag removal rod, and a limiting hole is provided at the tail end of the slag removal rod that runs vertically through the radial direction. The tail end of the slag removal rod passes through multiple insert plates. The limiting block cooperates with the insert plate located at the head to form an axial limit. The tail end of the slag removal rod passes through the insert plate located at the tail end and passes through the limiting hole through the limiting pin to form an axial limit. The axial position of the slag removal rod is limited by the limiting block and the limiting pin to prevent the slag removal rod from the insert part. It can also quickly lock or release the connection between the slag removal rod and the insert part.

[0016] 3. The slag removal plate is composed of an upper trapezoidal plate and a lower rectangular block, which makes the effective slag removal and mixing area of ​​the slag removal plate larger, and also reduces the overall weight of the slag removal plate.

[0017] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

Detailed Implementation

[0020] See Figures 1 to 5, which is a specific embodiment of a slag skimming device for an aluminum liquid melting furnace. The slag skimming device for the aluminum liquid melting furnace includes a forklift 1 and a slag skimming rod 2. Among them, an enterprise-supplied forklift can be used. A slag skimming plate 3 is provided at the head end of the slag skimming rod 2, and an insertion part 4 is provided at the tail end of the slag skimming rod 3, and the height of the insertion part 4 is higher than the height of the slag skimming plate 3. In this embodiment, the slag skimming rod is made of a steel pipe. Generally, the length of the steel pipe corresponds to the diameter of the melting furnace. The slag skimming plate 3 is composed of a trapezoidal plate 31 on the upper part and a rectangular block 32 on the lower part as a whole. Generally, in order to ensure the structural strength, the slag skimming plate is made of a rectangular steel plate. The two corners of the upper part of the rectangular steel plate are cut to form the trapezoidal plate on the upper part and the rectangular plate on the lower part. The head of the slag skimming rod 2 is welded to the trapezoidal plate 31, and a reinforcing rib is provided between the slag skimming rod 2 and the trapezoidal plate 31. Obviously, the slag skimming rod and the trapezoidal plate are vertically distributed. Generally, the head of the steel pipe is compressed into a flat pipe and bent at an angle so that the front side of the flat pipe is welded to the trapezoidal plate. The insertion part 4 includes a base plate 41 and insertion cylinders 42 welded and fixed on both sides of the bottom surface of the base plate 41. The cross-section of the insertion cylinder 42 is rectangular. Three insertion plates 43 are arranged at intervals along the length direction of the insertion cylinder on the top surface of the base plate between the two insertion cylinders 42. In order to ensure the strength, reinforcing plates 44 are provided at both ends of the three insertion plates 43. The reinforcing plates 44 are welded to both the base plate 41 and the insertion plates 43 to form a "day" character structure. Obviously, a through hole for the slag skimming rod to pass through is provided in the middle of the bottom of the insertion plate. The tail end of the slag skimming rod 2 passes through multiple insertion plates 43 and is locked in position. Specifically, a limiting block 5 is provided on the slag skimming rod 2, and a limiting hole 6 vertically penetrating in the radial direction is provided at the tail end of the slag skimming rod 2. The tail end of the slag skimming rod 2 passes through three insertion plates 43. The limiting block 5 cooperates with the insertion plate at the head to form axial limitation. The tail end of the slag skimming rod 2 passes through the insertion plate at the tail, and an axial limitation is formed by passing a limiting pin 7 through the limiting hole 6. The slag skimming rod 2 is detachably assembled on the fork arm of the forklift 1 through the insertion part 4 to form a slag skimming device for the aluminum liquid melting furnace.

[0021] The working principle of the present invention is as follows: The slag skimming rod is usually placed on the factory floor. The forklift moves and controls the movement of the fork arm, inserts it into the insertion cylinder of the insertion part at the tail end of the slag skimming rod, and raises the fork arm so that the height of the slag skimming rod can be adjusted. The forklift operator controls the forklift and the fork arm to make the slag skimming plate of the slag skimming rod enter the furnace through the furnace door. By controlling the forward and backward movement of the forklift and coordinating the adjustment of the height of the fork arm, the slag skimming plate is controlled to skim the floating slag to the furnace threshold. With the help of manual use of tools or continuing to control the forklift and the fork arm, the slag can be skimmed out of the melting furnace along the inclined surface of the furnace threshold. The entrained aluminum liquid flows back into the furnace along the inclined surface of the furnace threshold under the action of gravity. After the slag separation is completed, the height of the fork arm is controlled so that the lower part of the slag skimming plate is immersed in the aluminum liquid. The forklift is controlled to move back and forth and the orientation of the fork arm is changed by coordinating the rotation direction to achieve the purpose of stirring the aluminum liquid.
