Description
Technical Field
[0001] The utility model relates to the technical field of metal melting furnaces, and particularly relates to a heat preservation system for a metal melting furnace. Background Art
[0002] After recycling waste metals, since the waste metals still have certain uses, usually the waste metals will be first melted into a liquid state and then subjected to a casting and molding operation. When performing the melting operation, it is usually completed in a corresponding metal melting furnace device. The metal melting furnace device includes two parts. One part is a container for holding waste metals, and the other part is a furnace body. The container is sent into the furnace body for heating to complete the melting operation.
[0003] Since a heat preservation door is provided on the melting furnace, after closing the heat preservation door, the heat dissipation during the melting process can be reduced, achieving a heat preservation effect. However, when a conventional melting furnace is in use, it lacks components that can automatically close or open the heat preservation door. When manually opening the heat preservation door, after opening, a large amount of heat in the furnace body will escape outward. At this time, the temperature of the door body and the escaping heat will rush towards the human body side, easily causing the human body to be burned, posing a certain safety hazard and bringing inconvenience to users. Therefore, we propose a heat preservation system for a metal melting furnace. Summary of the Utility Model

The transportation assembly 3 includes a placement plate 5. The heat preservation door 2 is fixed to one side of the top of the placement plate 5. The placement plate 5 is slidably arranged in the furnace body 1. A driving member 6 for driving the movement of the placement plate 5 is arranged outside the furnace body 1. The locking assembly 4 includes a locking head 7. A plurality of fixing plates 8 are uniformly fixed outside the furnace body 1. One end of the fixing plate 8 extends out of the furnace body 1 and is fixed with a mounting frame 9. The locking head 7 penetrates through the fixing plate 8 and is slidably connected with the fixing plate 8. Limiting openings 10 are uniformly arranged outside the heat preservation door 2. The inside of the limiting opening 10 is an inclined surface. An auxiliary member 11 for driving the movement of the fixing plate 8 is arranged in the mounting frame 9. Support bars 18 are symmetrically fixed in the furnace body 1. The support bars 18 are located below the placement plate 5 and are used to support the placement plate 5. The placement plate 5 is fitted with the inner plane of the furnace body 1, and the melting furnace tank on the placement plate 5 is sealed between the placement plate 5, the furnace body 1 and the heat preservation door 2, and the heat preservation effect is better.
[0024] Next, some embodiments of the present application will be described in detail with reference to the accompanying drawings:
[0025] Please refer toFigures 1-4 , drive the placement plate 5 and the heat preservation door 2 to move together through the driving member 6, place the smelting furnace tank into the furnace body 1, and then drive the locking head 7 to slowly insert into the limiting port 10 through the auxiliary member 11. Since the inner part of the limiting port 10 is a slope, during the insertion process of the locking head 7, the end of the locking head 7 is always pressed against the inside of the limiting port 10, gradually pressing the heat preservation door 2 tightly against the furnace body 1 to complete the heat preservation and sealing operation.
[0026] Among them, the driving member 6 includes a driving motor 12. A fixing frame 13 is fixedly arranged outside the furnace body 1. A first screw rod 14 is rotatably arranged inside the fixing frame 13. The driving motor 12 is fixed to the outer end of the fixing frame 13. One end of the first screw rod 14 penetrates through the fixing frame 13 and is fixedly connected to the output end of the driving motor 12. A slider 15 is fixedly arranged at the bottom of the heat preservation door 2. The first screw rod 14 is in threaded connection with the slider 15. By operating the driving motor 12, the heat preservation door 2 is opened, and the placement plate 5 and the smelting furnace tank are removed, without the need to manually open the heat preservation door 2.
[0027] Furthermore, as Figure 1 and Figure 2 shown, sliding rails 16 are symmetrically fixed to the inner bottom of the furnace body 1 and on the fixing frame 13. Multiple groups of rollers 17 are symmetrically fixed to the bottom of the placement plate 5. The rollers 17 are respectively rolling and embedded on the two sliding rails 16, facilitating the movement of the placement plate 5.
[0028] It should be noted that the auxiliary member 11 includes an auxiliary motor 19. The auxiliary motor 19 is fixed to the outside of the mounting frame 9. A second screw rod 20 is rotatably arranged inside the mounting frame 9. One end of the second screw rod 20 is located inside the locking head 7. The second screw rod 20 is in threaded connection with the locking head 7. The end of the second screw rod 20 away from the locking head 7 penetrates through the mounting frame 9 and is fixedly connected to the output end of the auxiliary motor 19, used to drive the locking head 7 to be locked in the limiting port 10. A limiting rod 21 is fixed inside the mounting frame 9. The end of the limiting rod 21 away from the auxiliary motor 19 is located inside the locking head 7, further restricting the movement direction of the locking head 7. A guiding surface 22 is provided at the end of the locking head 7 close to the heat preservation door 2, facilitating the insertion of the locking head 7 into the limiting port 10.

After the heat preservation door 2 is attached to the furnace body 1, by operating the auxiliary motor 19, the second screw rod 20 is driven to rotate, and then the locking head 7 is pushed forward towards the heat preservation door 2 through the threaded action between the second screw rod 20 and the locking head 7. The locking head 7 slowly inserts into the limiting port 10. Since the inner part of the limiting port 10 is a slope, during the insertion process of the locking head 7, the end of the locking head 7 is always pressed against the inside of the limiting port 10, slowly pressing the heat preservation door 2 tightly against the furnace body 1 bit by bit to complete the heat preservation and sealing operation, as Figure 1As shown, the heat preservation door 2 is pressed by the locking heads 7 evenly distributed on the outer side of the furnace body 1, so that the heat preservation door 2 fits more closely with the furnace body 1, which can effectively prevent the heat in the furnace body 1 from leaking out and achieve a better heat preservation effect.
[0030] As Figure 1 shown, by arranging rollers 17 at the bottom of the placement plate 5, the rollers 17 roll under the limitation of the slide rail 16, which can reduce the resistance of the placement plate 5 carrying the smelting furnace tank during movement and realize the rapid placement and removal of the smelting furnace tank.
