Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy liquid conveying technology, and in particular to an aluminum alloy liquid conveying device. Background Technology

[0002] Aluminum alloys, which are aluminum-based materials with the addition of certain amounts of other alloying elements, are a type of lightweight metal material. In addition to the general properties of aluminum, aluminum alloys also possess specific alloy characteristics due to the different types and amounts of alloying elements added. They have good casting and plastic processing properties, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials. They are widely used in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily consumer goods industries.

[0003] During the transportation of molten aluminum alloy or molten aluminum through pipelines, significant heat loss occurs due to the large temperature difference between the molten aluminum and the surrounding environment. This heat loss not only causes the temperature of the molten aluminum to drop, affecting the solidification rate and crystal structure of the casting, but also causes molten aluminum alloy to adhere to the inner wall of the pipeline. Therefore, an molten aluminum alloy transportation device is proposed to solve this problem. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] An aluminum alloy liquid conveying device includes:

[0006] Fixture;

[0007] An insulated box is movably mounted above the fixed frame. An open-bottomed insulated pipe is fixedly installed at the bottom of the insulated box. A partition is installed inside the insulated pipe, which divides the cavity of the insulated pipe into a heating area and an insertion area from top to bottom. Multiple air inlets are provided at the bottom of the insulated box to connect the heating area with the interior of the insulated box. Multiple air outlets are provided on the partition to connect the heating area with the insertion area. A movable part is provided between the air inlets and the air outlets.

[0008] A storage bucket is installed inside the insulated box by a support member. An insulated area is formed between the inner wall of the insulated box and the storage bucket. A discharge pipe is connected to the bottom of the storage bucket. The bottom of the discharge pipe passes through the bottom of the insulated box and the partition and extends into the insertion area.

[0009] The mold is located below the insulation box. The mold has a feed pipe at its inlet. An external force drives the insulation box to move downward until the feed pipe enters the insertion area and pushes the moving part upward. The air inlet opens, and the hot air in the insulation area enters the heating area through the air inlet to heat and keep the feed pipe warm.

[0010] As an improvement to the above technical solution, the moving component includes multiple sets of moving rods disposed between the air inlet and the air outlet. Each set of moving rods has a sealing plate at its top and bottom. When the moving rod moves upward, the air inlet opens and the sealing plate at the bottom of the moving rod seals the air outlet. When the moving rod moves downward under the action of gravity, the air outlet opens and the sealing plate at the top of the moving rod seals the air inlet.

[0011] As an improvement to the above technical solution, the diameters of the air inlet and air outlet are the same, and the diameters of both the air inlet and air outlet are larger than the diameter of the moving rod.

[0012] As an improvement to the above technical solution, an electric push rod is provided between the fixing frame and the insulation box.

[0013] As an improvement to the above technical solution, a valve is provided on the feeding pipe.

[0014] As an improvement to the above technical solution, the fixing frame is provided with a through hole for the insulation pipe to move up and down.

[0015] The beneficial effects of this utility model are:

[0016] When the molten aluminum alloy is delivered into the mold, the feed pipe on the mold comes into contact with the moving part and pushes it upward, which opens the air inlet. This allows the high-temperature gas stored in the heat preservation area to flow into the heating area through the air inlet. As the high-temperature gas in the heating area tightly wraps the feed pipe, it provides efficient heating and heat preservation, effectively preventing problems such as temperature drop, poor fluidity, and adhesion to the inner wall of the molten aluminum alloy due to heat loss when it flows through the feed pipe.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] An aluminum alloy liquid conveying device includes: a fixed frame 31;

[0024] The heat preservation box 10 is movably mounted above the fixed frame 31. A heat preservation pipe 11 with an open bottom is fixedly mounted on the bottom of the heat preservation box 10. A partition 12 is provided inside the heat preservation pipe 11. The partition 12 divides the cavity of the heat preservation pipe 11 into a heating area and an insertion area from top to bottom. The bottom of the heat preservation box 10 has multiple sets of air inlets 101 that communicate with the heating area and the interior of the heat preservation box 10. The partition 12 has multiple sets of air outlets 121 that communicate with the heating area and the insertion area. A movable part is provided between the air inlets 101 and the air outlets 121.

[0025] The storage bucket 20 is set inside the insulated box 10 by a support member. An insulated area is formed between the inner wall of the insulated box 10 and the storage bucket 20. A discharge pipe 21 is connected to the bottom of the storage bucket 20. The bottom of the discharge pipe 21 passes through the bottom of the insulated box 10 and the partition 12 and extends into the insertion area.

[0026] The mold 40 is located below the heat preservation box 10. The mold 40 has a feed pipe 41 at its inlet. When the heat preservation box 10 is moved down by external force, the feed pipe 41 enters the insertion area and pushes the moving part up. The air inlet 101 is opened, and the hot air in the heat preservation area enters the heating area through the air inlet 101 to heat and keep the feed pipe 21 warm.

[0027] The movable component includes multiple sets of movable rods 14 disposed between the air inlet 101 and the air outlet 121. Each set of movable rods 14 has a sealing plate 13 at its top and bottom. When the movable rod 14 moves upward, the air inlet 101 opens and the sealing plate 13 at the bottom of the movable rod 14 seals the air outlet 121. When the movable rod 14 moves downward under the action of gravity, the air outlet 121 opens and the sealing plate 13 at the top of the movable rod 14 seals the air inlet 101.

[0028] In the initial state, the storage bucket 20 is stably placed inside the insulation box 10 by the support members. At this time, there is high-temperature gas in the insulation area between the insulation box 10 and the storage bucket 20. The feed pipe 21 is in its natural state, with its bottom extending into the insertion area. The moving rod 14 is at its lowest position under the action of gravity, so that the sealing plate 13 at the top of the moving rod 14 blocks the air inlet 101 to prevent the high-temperature gas in the insulation area from leaking out. At the same time, the sealing plate 13 at the bottom of the moving rod 14 is a certain distance from the air outlet 121, so the air outlet 121 is open. In this state, the hot air inside the insulation box 10 can flow in the insulation area to keep the molten aluminum alloy inside the storage tank warm. When it is necessary to transfer the molten aluminum alloy into the mold 40, external force begins to drive the insulation box 10 to move downward. As the insulation box 10 moves downward, the feed pipe 41 of the mold 40 below it gradually approaches and eventually enters the insertion area. During this process, the feed pipe 41 will contact the moving rod 14 and push it upward. Once the moving rod 14 moves upward, the sealing plate 13 at its top moves upward. As the moving rod moves upward, the air inlet 101 is opened, allowing the high-temperature gas stored in the insulation area to flow into the heating area through the air inlet 101. Simultaneously, the sealing plate 13 at the bottom of the moving rod 14 moves upward to block the air outlet 121, obstructing the path of the high-temperature gas in the heating area from the air outlet 121. Because the high-temperature gas in the heating area tightly wraps around the feeding pipe 21, it efficiently heats and insulates the feeding pipe 21, effectively preventing problems such as temperature drop and decreased fluidity caused by heat loss when the aluminum alloy liquid flows through the feeding pipe 21. Furthermore, when the insulation box 10 moves upward, the moving rod 14 moves downward under the action of gravity, returning to the initial state. The vent 121 opens, allowing the high-temperature gas in the heating area to flow into the insertion area. This hot gas can continuously heat the aluminum alloy liquid that may remain in the feeding pipe 21 in the insertion area, keeping it at a certain fluidity. This effectively avoids the problem of aluminum alloy liquid adhering to the feeding pipe 21 and solidifying as the temperature decreases, ultimately causing blockage. This prepares the ground for the next aluminum alloy liquid transportation operation and maintains the good operating condition of the device.

[0029] In one embodiment, the diameters of the air inlet 101 and the air outlet 121 are the same, and the diameters of both the air inlet 101 and the air outlet 121 are larger than the diameter of the moving rod 14. The same aperture of the air inlet 101 and the air outlet 121 ensures that the sealing plate 13 can block both of them. The fact that the apertures of the air inlet 101 and the air outlet 121 are larger than the diameter of the moving rod 14 is to allow gas to flow through the gap between the moving rod and the air inlet 101 and the air outlet 121.

[0030] In one embodiment, an electric push rod 30 is provided between the fixing frame 31 and the insulation box 10, and the electric push rod 30 is used to push the insulation box 10 up and down.

[0031] In one embodiment, a valve is provided on the feed pipe 21, and the aluminum alloy liquid can be conveyed by opening or closing the valve.

[0032] In one embodiment, the fixing frame 31 has a through hole 311 for the insulation pipe 11 to move up and down, providing a guiding function for the insulation box 10 to move down.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
