Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot processing technology, and in particular to an aluminum ingot melting furnace. Background Technology

[0002] Aluminum is a silvery-white metal, the third most abundant metal in the Earth's crust after oxygen and silicon. Because of its low density, aluminum is also known as a light metal. Aluminum is the world's second most produced and consumed non-ferrous metal after steel. Due to its light weight, aluminum is often used in the manufacture of land, sea and air transportation vehicles such as automobiles, trains, subways, ships, airplanes, rockets and spacecraft to reduce weight and increase load capacity.

[0003] Existing technologies, such as the aluminum ingot melting furnace disclosed in CN219869078U, include a melting furnace with a protective cover fixedly installed on its exterior. A cover plate is also installed at the top of the melting furnace. A heating plate for heating the aluminum ingot is embedded in the inner wall of the melting furnace. A filter plate for filtering the molten aluminum is also located inside the protective cover, below the melting furnace. This technology, through the use of a stirring rod and a cooperating fixing rod, facilitates rapid melting of the aluminum ingot during processing by utilizing the interlacing and rotation of the crossbar and fixing rod. It also uses the filter plate to filter the molten aluminum, removing impurities and improving the quality of the molten aluminum. However, the following problems exist in its use:

[0004] The above technology collects molten aluminum through a feeding platform. During the collection process, the molten aluminum will cool down when it leaves the reactor and flows out of the outlet. This can cause the molten aluminum to cool down and solidify too quickly, which can easily lead to blockage of the outlet in severe cases. Utility Model Content

[0005] The purpose of this invention is to solve the problem of excessive cooling and clogging of the outlet when molten aluminum flows out of the reactor in the prior art. Therefore, an aluminum ingot melting furnace is proposed.

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

[0007] An aluminum ingot melting furnace includes a base plate, two side plates fixedly installed on the upper part of the base plate, and a rotating shaft rotatably connected to the inner wall of each side plate. A furnace body disposed between the two side plates is fixedly connected to the end of the rotating shaft. An arc-shaped heat-conducting plate is fixedly installed inside the furnace body. A melting chamber for stirring the aluminum ingot is opened in the upper part of the furnace body relative to the heat-conducting plate, and a heating chamber for heating the heat-conducting plate is opened in the lower part of the furnace body relative to the heat-conducting plate. A stirring mechanism for stirring the aluminum ingot is provided in the melting chamber.

[0008] Preferably, the stirring mechanism includes an electric telescopic rod, a mounting plate is fixedly installed on the top of the electric telescopic rod, a drive motor is fixedly installed on the upper part of the mounting plate, a stirring rod is fixedly installed at the output end of the drive motor, and stirring blades for stirring aluminum ingots are fixedly installed on the outer wall of the stirring rod.

[0009] Preferably, the electric telescopic rod is located on the upper part of the side plate, the drive motor is fixedly installed on the upper part of the mounting plate, and the stirring rod is located directly above the furnace body.

[0010] Preferably, a high-torque motor for driving the rotating shaft to rotate is fixedly installed on the outer wall of the side plate, a heating groove for transmitting the temperature inside the heating chamber is opened in the heat-conducting plate, and a heat-conducting block for transferring the temperature inside the heating chamber to the melting chamber is fixedly installed at the center of the bottom of the heat-conducting plate.

[0011] Preferably, a heating plate for heating the melting chamber is fixedly installed in the heating cavity located below the heat-conducting plate in the furnace body, and the upper part of the heating plate is fixedly connected to the bottom of the heat-conducting block.

[0012] Preferably, the upper part of the furnace body is provided with an outlet for pouring out the molten aluminum inside the furnace, and four chains are fixedly installed on the lower part of the mounting plate, with a cover plate for sealing the furnace body fixedly installed on the lower part of the chains.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model uses stirring blades to fully stir the furnace body, and then turns on a high-torque motor to drive the rotating shaft to rotate, so that the furnace body rotates with the rotating shaft as the center, so that the molten aluminum in the furnace body flows out from the outlet. This avoids the molten aluminum from cooling down when it leaves the reaction furnace and flows out of the outlet, and avoids the molten aluminum cooling down and forming, which would cause the outlet to be blocked.

[0015] 2. This utility model uses an electric telescopic rod to drive the mounting plate downwards, causing the chain set at the bottom of the mounting plate to move synchronously. This prevents the cover plate from continuing to descend when it moves to the top of the furnace body, thus preventing the cover plate from opening and causing the temperature inside the furnace body to drop when the stirring mechanism is performing vertical stirring, achieving a good heat preservation effect.

Detailed Implementation

[0021] 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.

[0022] Reference Figures 1-4 An aluminum ingot melting furnace includes a base plate 1, two side plates 2 are fixedly installed on the upper part of the base plate 1, and a rotating shaft 8 is rotatably connected to the inner wall of each of the two side plates 2. A furnace body 10 disposed between the two side plates 2 is fixedly connected to the end of the rotating shaft 8. An arc-shaped heat-conducting plate 11 is fixedly installed inside the furnace body 10. A melting chamber 13 for stirring aluminum ingots is opened in the furnace body 10 relative to the upper part of the heat-conducting plate 11. A heating chamber 14 for heating the heat-conducting plate 11 is opened in the furnace body 10 relative to the lower part of the heat-conducting plate 11. A stirring mechanism for stirring aluminum ingots is provided in the melting chamber 13.

[0023] The stirring mechanism includes an electric telescopic rod 3, an installation plate 4 is fixedly installed on the top of the electric telescopic rod 3, a drive motor 5 is fixedly installed on the upper part of the installation plate 4, a stirring rod 6 is fixedly installed at the output end of the drive motor 5, and a stirring blade 7 for stirring aluminum ingots is fixedly installed on the outer wall of the stirring rod 6.

[0024] The electric telescopic rod 3 is set on the upper part of the side plate 2, the drive motor 5 is fixedly installed on the upper part of the mounting plate 4, and the stirring rod 6 is set directly above the furnace body 10 to avoid uneven stirring when the stirring rod 6 stirs the aluminum ingots;

[0025] A high-torque motor 9 for driving the rotating shaft 8 to rotate is fixedly installed on the outer wall of the side plate 2. A heating groove 12 for transferring the temperature inside the heating chamber 14 is opened in the heat-conducting plate 11, and a heat-conducting block 16 for transferring the temperature inside the heating chamber 14 to the melting chamber 13 is fixedly installed at the center of the bottom of the heat-conducting plate 11.

[0026] A heating plate 15 for heating the melting chamber 13 is fixedly installed in the heating chamber 14 located below the heat-conducting plate 11 in the furnace body 10. The upper part of the heating plate 15 is fixedly connected to the bottom of the heat-conducting block 16. Heat is transferred to the heat-conducting block 16 through the heating plate 15, so that the heat-conducting block 16 melts the aluminum ingot on the heat-conducting plate 11. Then, through the two heating grooves 12, the temperature on the heat-conducting plate 11 is made uniform and heat preservation effect is achieved.

[0027] The upper part of the furnace body 10 is provided with an outlet 17 for pouring out the molten aluminum inside the furnace body 10. Four chains 18 are fixedly installed on the lower part of the mounting plate 4. A cover plate 19 for sealing the furnace body 10 is fixedly installed on the lower part of the chains 18. By extending and retracting the chains 18, the movement of the mounting plate 4 in a certain vertical direction will not affect the movement of the cover plate 19, thus preventing the cover plate 19 from falling off the top of the furnace body 10 and causing the temperature inside the furnace body 10 to drop.

[0028] The functional principle of this utility model can be explained through the following operation methods:

[0029] By placing aluminum ingots into the furnace body 10 and then turning on the heating plate 15, the heating plate 15 raises the temperature inside the heating chamber 14. Then, through the heat-conducting block 16 set on the upper part of the heating plate 15, the aluminum ingots on the upper part of the heat-conducting plate 11 are quickly melted. In addition, the temperature of the heat-conducting plate 11 is transferred to the two heating tanks 12, so that the aluminum ingots are melted efficiently and the molten aluminum is prevented from cooling down rapidly when the heating plate 15 is stopped.

[0030] When the aluminum ingot is melted, the drive motor 5 is turned on to drive the stirring rod 6 to rotate, and the stirring rod 6 drives the stirring blade 7 to stir the aluminum ingot horizontally. Then, the electric telescopic rod 3 is turned on to drive the mounting plate 4 to move up and down, so that the stirring blade 7 stirs the aluminum ingot vertically, making the stirring more thorough.

[0031] After stirring is completed, the electric telescopic rod 3 is activated, which pushes the mounting plate 4 to its highest position. The stirring rod 6 will then disengage from the furnace body 10 and move upward along with the cover plate 19 via the chain 18 fixedly connected to the lower part of the mounting plate 4. The cover plate 19 will then move to the upper part of the furnace body 10. Then, the high-torque motor 9 is activated, which drives the rotating shaft 8 to rotate. This causes the furnace body 10 to rotate with the rotating shaft 8 as the center, allowing the molten aluminum in the furnace body 10 to flow out from the outlet 17.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
