Aluminum alloy smelting and impurity removing device

Abstract

This utility model provides an aluminum alloy smelting and impurity removal device, belonging to the field of aluminum alloy smelting, including a smelting furnace; a support, on which a lifting mechanism is provided, and on which an impurity removal mechanism is provided; a support shell, which is fixed to the bottom of the lifting mechanism; and a gear ring, which is rotatably connected inside the support shell. This utility model, through the cooperation of a sliding seat, a driving component, and a cleaning component, can automatically clean impurities adhering to the inclined section of the smelting furnace. When the driving component drives the cleaning spoon into the smelting furnace, due to the structural design, the cleaning spoon rotates away from the inclined section, avoiding direct contact between the cleaning spoon and the inclined section, which would cause the impurities on it to detach and fall off. When the cleaning spoon is retrieved, it rotates towards the inclined section, causing the cleaning spoon to contact the inclined section and push the impurities adhering to the inclined section away, allowing them to fall into the cleaning spoon for collection, thus completing the impurity removal operation.

Description

Technical Field

[0001] This utility model relates to aluminum alloy smelting technology, specifically an aluminum alloy smelting and impurity removal device. Background Technology

[0002] During the smelting process of aluminum alloys, due to the excessively high temperature, the molten aluminum often contains hydrogen gas produced by the high-temperature decomposition of water vapor, as well as a large number of non-metallic inclusions generated by the interaction between the aluminum alloy solution and the furnace wall refractory materials, refining agents, smelting tools, etc. Therefore, it is necessary to remove impurities during the smelting of aluminum alloys.

[0003] In existing smelting furnaces with inclined sections, the impurity removal process is complex and often requires manual labor. Impurities adhering to the inclined section are separated by the pushing force and fall into the spoon. Afterward, the handle containing the impurities is removed, and the remaining impurities are dumped out. This manual method is slow, and errors can easily lead to impurities falling into the molten aluminum, affecting its quality. Therefore, we propose an impurity removal device for aluminum alloy smelting to address these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an aluminum alloy smelting and impurity removal device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: including a smelting furnace;

[0006] A support, wherein a lifting mechanism is provided on the support, and a debris removal mechanism is provided on the lifting mechanism;

[0007] A support shell, which is fixed to the bottom of the lifting mechanism;

[0008] A gear ring, which is rotatably connected within the support housing;

[0009] A rotating assembly, which is connected to a gear ring and a support shell;

[0010] A sliding seat, which is fixed to the bottom of the gear ring;

[0011] A driving component, which is fixedly mounted on one side of the sliding seat;

[0012] The cleaning assembly includes a cleaning spoon rotatably connected to the output end of the drive component. Push-pull brackets are fixed on the front and rear sides of the cleaning spoon, and guide rods are fixed on the opposite sides of the push-pull brackets. Damping rods are provided on the front and rear sides of the sliding seat, and curved brackets are fixed on the opposite sides of the damping rods. Adjacent guide rods are movably connected within the curved brackets.

[0013] Preferably, it also includes a collection component, the collection component including a support integrally formed with the cleaning spoon, the support being externally threaded with a collar.

[0014] Preferably, the rotating assembly includes a motor fixed to one side of the top of the support shell, and the output end of the motor is connected to a gear via a rotating shaft, the gear meshing with a gear ring.

[0015] Preferably, the sliding seat has sliding grooves on its front and rear sides, and the damping rod is slidably connected to the adjacent sliding grooves through damping blocks.

[0016] Preferably, the bending frame is arc-shaped, with the center of the arc on the straight line where the cleaning spoon and the drive component rotate.

[0017] Preferably, the smelting furnace is fixedly provided with an inclined section, and the inner edge of the cross section of the inclined section is parallel to one side edge of the sliding seat.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Through the cooperation of the sliding seat, driving component and cleaning component, the impurities attached to the inclined part of the smelting furnace can be automatically cleaned. When the driving component drives the cleaning spoon into the smelting furnace, due to the structural design, the cleaning spoon will rotate away from the inclined part to avoid the cleaning spoon directly contacting the inclined part and causing the impurities on it to fall off directly. When the cleaning spoon is retrieved, the cleaning spoon will rotate towards the inclined part, so that the cleaning spoon comes into contact with the inclined part and pushes the impurities attached to the inclined part to detach from the inclined part and fall into the cleaning spoon for collection, thereby completing the impurity removal operation.

[0020] 2. By cooperating with the set rotating component and toothed ring, after the impurities at one angle are cleaned, the cleaning spoon can be rotated to another angle in the inclined section to continue cleaning, so as to achieve a complete cleaning operation around the inclined section and a thorough cleaning.

[0021] 3. By using the collection components, the capacity of the cleaning spoon can be increased. Impurities falling into the cleaning spoon will be temporarily stored in the cylindrical area with a bottom formed by the support and the collar. When it is necessary to empty the impurities in the cleaning spoon, the collar can be rotated with a tool to separate it from the support, so that the impurities stored inside will fall off naturally under the action of gravity, thus avoiding the problem of short cleaning time per session due to the small capacity of the cleaning spoon.

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Please see Figures 1-5 As shown, an aluminum alloy smelting and impurity removal device includes a smelting furnace 1;

[0031] Support 2, lifting mechanism 3 is provided on support 2, impurity removal mechanism is provided on lifting mechanism 3, support 2 is used to fix lifting mechanism 3, lifting mechanism 3 is used to drive impurity removal mechanism to lift, impurity removal mechanism is used to introduce inert gas and refining agent into aluminum liquid to remove hydrogen and oxide inclusions in the melt. This part is an existing mature structure.

[0032] Support shell 5 is fixed at the bottom of lifting mechanism 3 and is used to fix and support gear ring 6.

[0033] The gear ring 6 is rotatably connected inside the support shell 5. The gear ring 6 and the rotating component work together to drive the cleaning spoon 9 to rotate and clean the inclined part 4 on the melting furnace 1.

[0034] The sliding seat 7 is fixed to the bottom of the gear ring 6 and is used to install the drive component 8 and the cleaning assembly;

[0035] The driving component 8 is fixed on one side of the sliding seat 7. The driving component 8 can be any linear movement mechanism, such as a cylinder or an electric cylinder, which can drive the cleaning spoon 9 to move linearly along the tilt direction of the sliding seat 7. It is used to enable the cleaning spoon 9 to remove impurities and retract.

[0036] The cleaning assembly includes a cleaning spoon 9 rotatably connected to the output end of the drive unit 8. Push-pull brackets 10 are fixed on the front and rear sides of the cleaning spoon 9, and guide rods 11 are fixed on the opposite sides of the push-pull brackets 10. Damping rods 12 are provided on the front and rear sides of the sliding seat 7, and bending brackets 13 are fixed on the opposite sides of the damping rods 12. Adjacent guide rods 11 are movably connected within the bending brackets 13.

[0037] It should be noted that the guide rod 11 is used to cooperate with the inner groove of the bending frame 13 to further restrict the rotation of the cleaning spoon 9 at the output end of the drive member 8 through the bending frame 13. This facilitates different bending angles of the cleaning spoon 9 when it extends and retracts with the drive member 8, so that when the cleaning spoon 9 is extended, it rotates away from the inclined part 4, and when it is retracted, it abuts against the inclined part 4 to scrape off the impurities attached to it. The damping rod 12 is used to allow the bending frame 13 to be driven linearly by the cleaning spoon 9, so that it moves synchronously with the cleaning spoon 9. This is achieved through the provided sliding seat 7 and drive member 8. The cooperation between the actuator 8 and the cleaning assembly enables automated cleaning of impurities attached to the inclined section 4 of the smelting furnace 1. When the actuator 8 drives the cleaning spoon 9 into the smelting furnace 1, due to the structural design, the cleaning spoon 9 will rotate away from the inclined section 4 to avoid direct contact between the cleaning spoon 9 and the inclined section 4, causing the impurities on it to fall off directly. When the cleaning spoon 9 is retrieved, it will rotate towards the inclined section 4, causing the cleaning spoon 9 to come into contact with the inclined section 4, pushing the impurities attached to the inclined section 4 to detach from the inclined section 4 and fall into the cleaning spoon 9 for collection, thus completing the impurity removal operation.

[0038] In this embodiment, a collection component is also included. The collection component includes a support 14 integrally formed with the cleaning spoon 9. A collar 15 is threaded onto the support 14. The collar 15 closes the bottom end of the support 14, thus forming a single-opening sealed chamber within the support 14. Impurities pushed into the cleaning spoon 9 will slide down into the chamber and be temporarily stored. When it is necessary to clean the impurities in the chamber, the outer wall of the collar 15 can be pinched and rotated with a tool such as pliers to separate it from the support 14, thereby opening the bottom end of the support 14 and allowing the impurities inside the support 14 to fall downwards.

[0039] In this embodiment, the rotating assembly includes a motor 16 fixed on one side of the top of the support shell 5. The output end of the motor 16 is connected to a gear 17 via a rotating shaft. The gear 17 meshes with the gear ring 6. The motor 16 drives the gear 17 to rotate and mesh with the gear ring 6, thereby driving the sliding seat 7 and the cleaning spoon 9 to rotate at a certain angle. Then, the driving component 8 continues to control the cleaning spoon 9 to remove the impurities attached to the inclined section 4 at this angle, so as to achieve a complete cleaning operation of the inclined section 4 around the perimeter, and the cleaning is thorough.

[0040] In this embodiment, sliding grooves are provided on the front and rear sides of the sliding seat 7. The damping rod 12 is slidably connected to the adjacent sliding groove through the damping block. The damping block can increase the friction force of the damping rod 12 when sliding by cooperating with the sliding groove, so that after the cleaning spoon 9 is extended, it will not immediately drive the damping rod 12 to slide out. Instead, the guide rod 11 will be driven to rotate in the bending frame 13 through the push-pull bracket 10 to change the angle of the cleaning spoon 9. At the same time, when the cleaning spoon 9 is pushed to the farthest point and then retracted, the cleaning spoon 9 will also first reset the angle and then pull the damping rod 12 to push it back, so as to realize the angle control of the cleaning spoon 9.

[0041] In this embodiment, the bending frame 13 is arc-shaped, and the center of the arc is on the straight line where the cleaning spoon 9 and the drive component 8 rotate.

[0042] In this embodiment, an inclined section 4 is fixedly provided on the smelting furnace 1. The inner edge of the cross section of the inclined section 4 is parallel to one side edge of the sliding seat 7. The parallelism restricts the direction of the cleaning spoon 9 to be pushed out and retracted, ensuring that the cleaning spoon 9 can continue to contact the inner wall of the inclined section 4 when it is retracted, so as to fully clean the impurities on the inner wall of the inclined section 4.

[0043] In practical implementation, when it is necessary to remove impurities attached to the inclined section 4 inside the smelting furnace 1, the drive component 8 in the device can be controlled by the controller to operate, which drives the cleaning spoon 9 to extend. The cleaning spoon 9 will rotate around the part in contact with the drive component 8, and the guide rod 11 will slide inside the bent frame 13 through the push-pull frame 10 until one end of the bent frame 13 abuts against the outer wall of the cleaning spoon 9. After that, the cleaning spoon 9 can no longer rotate. Then, the extended cleaning spoon 9 will pull the damping rod 12 through the connecting structure to move the bent frame 13 out synchronously. At this time, the end face of the cleaning spoon 9 forms a certain angle with the inner wall of the inclined section 4, but does not contact it. After the cleaning spoon 9 moves to the farthest end with the output end of the drive unit 8, the drive unit 8 drives the cleaning spoon 9 to retract. At this time, the cleaning spoon 9 immediately rotates in the opposite direction until one end contacts and squeezes the inclined part 4. Then, the cleaning spoon 9 is pushed back to its original position by the damping rod 12 through the push-pull bracket 10. At the same time, the cleaning spoon 9 in contact with the inclined part 4 will continuously rub and push the impurities attached to the inclined part 4 to fall off and fall into the support 14 inside the cleaning spoon 9 for storage until the cleaning spoon 9 is completely reset. Then, the controller controls the motor 16 to drive the gear 17 to rotate, and the gear 17 drives the gear ring 6 to rotate, so that the sliding seat 7 drives the cleaning spoon 9 to rotate a certain angle. Then, the above steps are repeated.
