Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot casting technology, and in particular to an aluminum liquid distribution device for aluminum ingot casting. Background Technology

[0002] In an aluminum ingot casting production line, molten aluminum flows from the mixing furnace through chutes and boat-shaped ladles into an aluminum liquid distribution device. The aluminum liquid distribution device precisely controls the flow rate and distribution rhythm of the molten aluminum, evenly injecting it into each mold to form aluminum ingots.

[0003] A casting apparatus for producing aluminum ingots, disclosed in publication number "CN220659204U", includes an aluminum liquid distributor with a guide nozzle. The aluminum liquid distributor is placed inside a support frame. Rollers for rolling support of the aluminum liquid distributor are symmetrically arranged at the bottom of the support frame. A rotating shaft is coaxially arranged at the end of the aluminum liquid distributor and is rotatably connected to the support frame. A gear driven by a servo motor is arranged at the top of the support frame. An end face gear ring that meshes with the gear is coaxially arranged on the aluminum liquid distributor. The servo motor is fixed to the top of the support frame. A control display for controlling the servo motor is arranged on one side of the support frame.

[0004] The aforementioned device enables the aluminum liquid distributor to rotate stably. However, before the aluminum liquid is delivered to the distributor, aluminum dross is easily generated due to oxidation and other reasons. The device lacks a centralized treatment design for aluminum dross filtration and easy disassembly, which causes the aluminum liquid containing aluminum dross to directly enter the mold through the guide nozzle. This not only causes a large number of aluminum dross defects on the surface of the aluminum ingot, reducing product quality, but also requires manual scraping, which increases the labor intensity of manual scraping operations, leads to aluminum loss, and ultimately increases production costs. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing technologies being unable to effectively filter and centrally treat aluminum dross in molten aluminum, which leads to aluminum dross defects on the surface of aluminum ingots, reduced product quality, and the need for manual scraping of aluminum dross, resulting in high labor intensity and increased production costs. Therefore, this invention proposes an aluminum molten aluminum distribution device for aluminum ingot casting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Each of the two protruding plates has a limit groove inside. Each of the two limit grooves is equipped with a limit mechanism. Two mounting platforms are installed on the upper surface of the support plate. Each of the two mounting platforms has a placement groove on its upper surface. The outer surfaces of the two protruding plates are in contact with the placement groove. A stabilizing mechanism is provided on the outside of the aluminum liquid distributor. A driving mechanism is provided on the left side of the aluminum liquid distributor.

[0008] Preferably, the driving mechanism includes a driving carrier plate, which is fixedly connected to the casting frame.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4 An aluminum liquid distribution device for aluminum ingot casting includes a casting frame 1 and an aluminum liquid distributor 4. A support plate 5 is bolted to the upper surface of the casting frame 1. The bolt connection facilitates the disassembly and maintenance of the support plate 5 and makes it easier to replace components later.

[0026] The support plate 5 is equipped with an aluminum liquid conveying pipe 6. One end of the aluminum liquid conveying pipe 6 extends into the aluminum liquid distributor 4. The aluminum liquid conveying pipe 6 realizes the directional transmission of aluminum liquid and ensures that the aluminum liquid smoothly enters the aluminum liquid distributor 4.

[0027] A filter cylinder 7 is placed inside the aluminum liquid conveying pipe 6. A set of filter holes 8 are opened on the inner bottom wall of the filter cylinder 7. The filter holes 8 can filter out aluminum dross and improve the purity of the finished aluminum ingot.

[0028] A ring lug plate 9 is fixedly connected to the upper surface of the filter cylinder 7. Two protruding plates 10 are installed on the outer surface of the ring lug plate 9. The bottom surface of the ring lug plate 9 is in contact with the upper surface of the aluminum liquid conveying pipe 6. The ring lug plate 9 limits the filter cylinder 7 to prevent it from falling into the aluminum liquid conveying pipe 6.

[0029] Both protruding plates 10 have a limiting groove 13 inside, and both limiting grooves 13 are equipped with a limiting mechanism inside. The limiting mechanism can fix the protruding plate 10 and enhance the installation stability of the filter cartridge 7.

[0030] The limiting mechanism includes a pull plate 14, the outer surface of which is slidably connected to a limiting groove 13, which provides guidance for the pull plate 14.

[0031] A pull rod 15 is fixedly connected to the outer surface of the pull plate 14. The pull rod 15 passes through the limiting groove 13 and extends into the interior of the mounting platform 11. The pull rod 15 is slidably connected to the protruding plate 10 and the mounting platform 11 respectively. The pull rod 15 is inserted into the mounting platform 11 to firmly fix the protruding plate 10.

[0032] A spring 16 is fitted onto the outer surface of the pull rod 15. The two ends of the spring 16 are fixedly connected to the inner walls of the pull plate 14 and the limiting groove 13, respectively. The spring 16... Figure 4 In its natural state, the pull rod 15 cannot detach from the mounting platform 11 without external force, thus preventing the filter cartridge 7 from shifting under the impact of molten aluminum.

[0033] A handle 17 is fixedly connected to the upper surface of the pull plate 14. The handle 17 facilitates manual operation of the pull plate 14, improving the ease of operation of the limit mechanism.

[0034] Two mounting platforms 11 are installed on the upper surface of the support plate 5. Each mounting platform 11 has a placement groove 12 on its upper surface. The outer surfaces of the two protruding plates 10 are in contact with the placement groove 12. The protruding plates 10 cooperate with the placement groove 12 to achieve quick positioning of the filter cartridge 7 during installation.

[0035] A drive mechanism is provided on the left side of the aluminum liquid distributor 4. The drive mechanism includes a drive carrier plate 2, which is fixedly connected to the casting frame 1. The drive carrier plate 2 provides stable support for the first motor 3 to ensure drive stability. The first motor 3 is installed on the left side of the drive carrier plate 2. The output end of the first motor 3 is connected to the aluminum liquid distributor 4 through a connecting plate. The first motor 3 drives the aluminum liquid distributor 4 to rotate, and can continuously use each distribution nozzle to perform uninterrupted and uniform casting. This is an existing mature technology.

[0036] The aluminum liquid distributor 4 is equipped with a stabilizing mechanism, which includes a bottom support plate 21. The bottom support plate 21 is fixedly connected to the casting frame 1. Two brackets 22 are fixedly connected to the upper surface of the bottom support plate 21. Rollers 23 are installed inside the two brackets 22. The bottom support plate 21 cooperates with the brackets 22 to provide a support base for the rollers 23. The rollers 23 can reduce contact friction and reduce the resistance when the aluminum liquid distributor 4 rotates.

[0037] A stabilizing ring 19 is fixedly connected to the outer surface of the aluminum liquid distributor 4. A mating groove 20 is provided inside the stabilizing ring 19. The outer surfaces of the two rollers 23 abut against the mating groove 20. The mating groove 20 fits against the rollers 23 and can support the aluminum liquid distributor 4 to prevent excessive shaking during rotation, thereby enhancing the operational stability of the aluminum liquid distributor 4.

[0038] A set of distributing nozzles 18 are installed on the inner wall of the aluminum liquid distributor 4. A conveying device 24 is set below the casting frame 1. A set of aluminum ingot molds 25 are conveyed on the conveying device 24. The distributing nozzles 18 can accurately discharge the aluminum liquid, and the conveying device 24 realizes continuous conveying of the aluminum ingot molds 25.

[0039] Working principle: In the aluminum ingot casting production line, the molten aluminum flowing out of the mixing furnace is transported to the filter cylinder 7 through the chute and the boat-shaped ladle to filter the molten aluminum. The molten aluminum flows into the molten aluminum conveying pipe 6 through the filter holes 8 opened in the bottom wall of the filter cylinder 7 and is then transported into the molten aluminum distributor 4. The aluminum slag is intercepted in the filter cylinder 7.

[0040] The filter cartridge 7 is placed on the aluminum liquid conveying pipe 6 via the ring lug plate 9. The protruding plate 10 on the outer surface of the ring lug plate 9 is embedded in the placement groove 12 of the mounting platform 11, so that the limiting mechanism fixes the filter cartridge 7. The pull rod 15 connected to the pull plate 14 in the limiting groove 13 extends into the mounting platform 11. Since the spring 16 is in a natural state, it will not stretch on its own, which can prevent the pull rod 15 from falling off. The position of the protruding plate 10 in the placement groove 12 can be limited to prevent the filter cartridge 7 from being displaced under the impact of the aluminum liquid.

[0041] The first motor 3 on the drive plate 2 starts, and its output end drives the aluminum liquid distributor 4 to rotate through the connecting plate. During the rotation of the aluminum liquid distributor 4, the bracket 22 on the bottom support plate 21 in the stabilizing mechanism supports the roller 23. The roller 23 abuts against the mating groove 20 on the outer surface stabilizing ring 19 of the aluminum liquid distributor 4. Through the rolling support of the roller 23, the shaking of the aluminum liquid distributor 4 during rotation is reduced. During its rotation, the aluminum liquid in the aluminum liquid distributor 4 is evenly injected into the aluminum ingot mold 25 conveyed on the conveying equipment 24 below through the distribution nozzle 18 installed on the inner wall, thus completing the casting of the aluminum ingot.

[0042] When it is necessary to clean the aluminum slag inside the filter cylinder 7, the operator pulls the pull plate 14 by holding the lever 17. The pull plate 14 stretches the spring 16 and drives the pull rod 15 to be pulled out from the mounting platform 11, releasing the fixation of the convex plate 10. The filter cylinder 7 can then be removed from the aluminum liquid conveying pipe 6 for cleaning or replacement.
