Description

Technical Field

[0001] This utility model relates to the field of heat preservation furnace technology, specifically to an aluminum liquid heat preservation furnace. Background Technology

[0002] An aluminum molten metal holding furnace is primarily used to maintain the temperature of molten aluminum in its molten state, preventing it from cooling to temperatures unsuitable for casting or processing. During the transfer of molten aluminum from the melting furnace to casting or processing equipment, the holding furnace ensures safe and efficient transport. At high temperatures, molten aluminum readily reacts with oxygen in the air to form aluminum oxide. The furnace's sealed design helps reduce oxidation and maintain its purity. By maintaining the temperature of the molten aluminum, the holding furnace reduces waiting time during casting or processing, improving production efficiency. Stable temperatures help ensure the dimensional accuracy and quality of castings or processed products. The aluminum molten metal holding furnace is a crucial piece of equipment in the aluminum processing industry; it ensures the smooth operation of the aluminum processing process through heat preservation and transport of molten aluminum.

[0003] Chinese patent authorization announcement number CN219797892U, entitled "An Aluminum Liquid Holding Furnace," includes a furnace body and a pumping component. The furnace body has a furnace cavity, and a mounting portion is located on one side of the furnace body. The mounting portion has a mounting surface lower than the top surface of the furnace body, and the pumping component is mounted on the furnace body. The aluminum liquid holding furnace is internally equipped with an aluminum liquid pumping structure, allowing for external liquid supply without long-distance transport. It also utilizes the convection environment within the furnace cavity to maintain the temperature of the aluminum liquid during transport, thus enabling the entire aluminum liquid holding furnace to have a highly efficient liquid supply function.

[0004] The shortcomings of the above solution are as follows: Although the above solution can keep the furnace warm, it cannot guarantee the insulation effect during use. Over time, the insulation material of the furnace (such as ceramic fiber, asbestos, etc.) may age due to high temperature, humidity or chemical corrosion, resulting in a decrease in insulation performance. It also cannot seal the internal molten aluminum. Poor sealing will cause heat to be lost from the inside of the furnace to the external environment, reducing the insulation effect and increasing energy consumption. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum liquid heat preservation furnace to solve the technical problems in the prior art that cannot guarantee the heat preservation effect during use. Over time, the heat preservation materials (such as ceramic fiber, asbestos, etc.) of the heat preservation furnace may age due to high temperature, humidity or chemical corrosion, resulting in a decrease in heat preservation performance. Furthermore, the furnace cannot seal the internal aluminum liquid, and poor sealing will cause heat to be lost from the inside of the heat preservation furnace to the external environment, reducing the heat preservation effect and increasing energy consumption.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] An aluminum liquid holding furnace, comprising a holding shell;

[0008] The bottom of the insulation shell is connected to a base frame;

[0009] An inner furnace is connected to the base frame, and an installation groove is provided on the top of the inner furnace. A plug-in plate is connected to the insulation shell, and a top cover is detachably connected to the installation groove.

[0012] As a further embodiment of this utility model: a stabilizing plate is connected to the end of the foot support away from the base frame.

[0013] As a further embodiment of this utility model, the top cover is a transparent cover.

[0014] As a further embodiment of this utility model: a plug ring is connected to the top cover, and the plug ring is connected to the mounting groove.

[0015] As a further embodiment of this utility model: plug-in blocks are connected to both sides of the top cover, and plug-in plates are connected to the heat insulation shell, with the plug-in plates and plug-in blocks being configured to cooperate with each other.

[0016] As a further embodiment of this utility model, a partition is provided between the inner furnace and the insulation shell.

[0017] As a further embodiment of this utility model, the height of the flow guide plate is consistent with the height of the inner furnace.

[0018] As a further embodiment of this utility model: a sealing plate is provided on the top of the flow guide plate, and the sealing plate is disposed between the inner furnace and the heat preservation shell.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model's insulation shell is used for heat preservation and to prevent heat loss. The base frame supports the entire insulation furnace and has a drain port connected to the bottom. The feet are fixed to the end of the base frame away from the insulation shell to provide stability. The inner furnace serves as a container for molten aluminum and has an installation groove on the top. The top cover covers the top of the inner furnace and is connected to the insulation shell via a plug-in ring. The plug-in plate and plug-in block are used to connect the top cover and the insulation shell to ensure a seal. The partition is located between the inner furnace and the insulation shell. The liquid adding mechanism is used to add insulation liquid. The sealing plate is located between the inner furnace and the insulation shell to prevent heat and molten aluminum leakage. The insulation furnace can effectively maintain the temperature of the molten aluminum, reduce heat loss and leakage, and improve the energy efficiency and production efficiency of the insulation furnace.

[0021] 2. The insulation shell and the insulation material inside the partition work together to reduce heat loss to the outside and maintain the temperature of the molten aluminum in the inner furnace. The molten aluminum is added through the molten aluminum adding mechanism inside the partition, allowing the insulation liquid to flow into the partition from the outside through the guide plate and the outlet. When the molten aluminum in the inner furnace needs to be discharged, it is discharged through the flow channel and the outlet. The molten aluminum adding mechanism inside the partition can precisely control the amount of insulation liquid added, thereby more accurately controlling the temperature of the molten aluminum. The insulation liquid can flow into the partition from the outside through the guide plate and the outlet without opening the insulation furnace, reducing operational risks and complexity.
