Description

Technical Field

[0001] This invention relates to a feeding mechanism for a smelting furnace, belonging to the technical field of smelting furnace equipment. Background Technology

[0002] Currently, in aluminum alloy smelting production, gas-fired heating furnaces are generally used. In actual production, aluminum ingots need to be fed into the melting chamber of the furnace, heated, and melted. The molten aluminum flows into the holding chamber, and after refining and passing quality inspection, it is discharged and transferred to the next process. A chain drive transfers a material cart to the feeding tower, where the cart tilts, and the aluminum ingots fall into the melting chamber. A search revealed that Chinese patent CN220911984U discloses a feeding device for a furnace. In this patent, workers add the material to be melted to the feeding frame through the feeding port. Two lifting cylinders are activated to move the support rod, raising the feeding frame above the furnace body. Then, a moving cylinder pushes the mounting frame to move the feeding frame horizontally above the furnace body. A motor rotates the feeding frame, allowing the material to be poured into the furnace body through the feeding port. However, this patent requires manual handling of the material in the feeding frame, resulting in high labor intensity, long handling time, and low production efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a smelting furnace feeding mechanism that can reduce the need for manual handling, reduce labor intensity, shorten handling time, and thus improve production efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] A charging mechanism for a smelting furnace, comprising:

[0006] Mounting base;

[0007] Two inclined brackets are mounted on the mounting base, and the inclined brackets form a certain angle with the mounting base. The inclined brackets are provided with a first sliding channel.

[0008] A conveying hopper is provided with a placement slot, and at least one clamping assembly is installed in the placement slot. The clamping assembly includes a spring hinge and a movable clamping plate. The movable clamping plate is installed on the inner wall of the placement slot through the spring hinge. When subjected to external pressure, the movable clamping plate is adapted to flip downward at a certain angle.

[0009] The inclined support is also provided with a material-turning support, and the material-turning support is provided with a material-turning channel.

[0010] The conveying hopper is adapted to slide on the first sliding channel and / or the turning channel;

[0011] The lifting device includes a lifting drive motor, a first lifting wheel, a second lifting wheel, and a lifting rope. The lifting drive motor is mounted on the mounting base. The first lifting wheel is rotatably mounted on the top of the first sliding channel. The first lifting wheel and the second lifting wheel are coaxially arranged. The lifting rope is adapted to be wound around the first lifting wheel and connected to the conveying hopper. The movable end of the lifting drive motor is connected to the second lifting wheel via a synchronous belt.

[0012] The lifting drive is adapted to drive the first lifting wheel to rotate so as to move the conveying hopper upward along the first sliding channel to a specific position, and cooperate with the tipping channel to make the conveying hopper flip so as to put the material in the placement trough into the smelting furnace.

[0013] Furthermore, the conveying hopper is also provided with two first sliding wheel sets. Each first sliding wheel set includes a first support, a first connecting shaft, and a first sliding wheel. The first support is installed on the conveying hopper, the first connecting shaft is installed on the first support, and the first sliding wheel is connected to the first connecting shaft. The first sliding wheel is slidably fitted in the corresponding first sliding channel. The lifting rope is adapted to connect the first lifting wheel and the first sliding wheel. The top of the first sliding channel is also provided with a baffle. When the first sliding wheel slides to a predetermined position, it is blocked by the baffle.

[0014] Furthermore, the conveying hopper is also provided with two second sliding wheel sets. The second sliding wheel set includes a second support, a second connecting shaft, and a second sliding wheel. The second support is installed on the conveying hopper, the second connecting shaft is installed on the second support, and the second sliding wheel is connected to the second connecting shaft. The second sliding wheel is slidably fitted in the first sliding channel and / or the turning channel.

[0015] Furthermore, in order to allow the aluminum ingots to slide smoothly from the placement trough into the smelting furnace, the top of the conveying hopper is provided with a slope, and the slope forms a certain angle with the placement trough to facilitate the material to slide from the placement trough into the smelting furnace.

[0016] Furthermore, in order to prevent the material in the placement trough from falling during the conveying process, the conveying hopper is also equipped with a sliding door, which has a handle for easy gripping and is adapted to be opened to fill the placement trough with material.

[0017] Furthermore, in order to facilitate the tilting of the conveying hopper, a third support is provided on the conveying hopper. The third support is installed at the bottom of the conveying hopper and has a pushing hole.

[0018] Furthermore, in order to accurately detect the position of the conveying hopper and ensure that the flipping action is performed in the appropriate position, an infrared sensor is provided in the first sliding channel. The infrared sensor is adapted to sense the second sliding wheel and is adapted to be connected to an external controller.

[0019] Furthermore, in order to automatically realize the flipping action of the conveying hopper, an mounting plate is also installed on the inclined support. An electric push rod is hinged on the mounting plate. When the conveying hopper slides to a predetermined position, the infrared sensor senses the second sliding wheel and sends a signal to the external controller. The external controller controls the electric push rod to extend towards the push hole on the third support, pushing the third support to move so that the second sliding wheel slides into the flipping channel.

[0020] After adopting the above technical solution, the present invention has the following beneficial effects:

[0021] In this invention, when the equipment is in its initial state, the conveying hopper is located at the lowest point of the inclined support. The operator opens the sliding door and uses a forklift to lift the pallet containing aluminum ingots and place it into the placement slot of the conveying hopper. The forklift places the pallet containing aluminum ingots from top to bottom. The pallet presses down the movable plate so that the pallet can be placed at the bottom of the placement slot. After the pallet passes the movable plate, the movable plate bounces back to the initial position due to the force of the spring hinge, restricting the pallet at the bottom of the placement slot.

[0022] After the sliding door is closed, the lifting device starts to work. The lifting drive motor drives the first lifting wheel and the second lifting wheel to rotate through the synchronous belt, thereby driving the lifting rope wound on the first lifting wheel, so that the conveying hopper moves upward along the first sliding channel.

[0023] The upward movement of the conveying hopper causes the first and second sliding wheels to move upward as well. When the first sliding wheel slides to the top of the first sliding channel, it is blocked by a baffle. At this time, the infrared sensor in the first sliding channel senses the second sliding wheel and sends a signal to the external controller. The external controller controls the electric push rod to move. The electric push rod extends into the push hole on the third support. Due to the force of the electric push rod, the third support is pushed, causing the second sliding wheel to slide into the tipping channel, so that the conveying hopper flips with the first sliding wheel as the fulcrum. When the conveying hopper flips to a certain extent, the opening of the placement trough faces the external smelting furnace, and the material slides from the placement trough into the smelting furnace.

[0024] After the material is fed, the electric push rod retracts, and the conveying hopper returns to its upright position due to its own gravity. The second sliding wheel slides from the tipping channel to the first sliding channel, thus completing one feeding cycle. Attached Figure Description

[0030] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0031] like Figure 1-5 As shown, a charging mechanism for a smelting furnace includes:

[0032] Mounting base 1;

[0033] Two inclined brackets 2 are mounted on the mounting base 1. The inclined brackets 2 and the mounting base 1 form a certain angle. The inclined brackets 2 are provided with a first sliding channel 21.

[0034] The conveying hopper 3 is provided with a placement groove 31. Two clamping components are also installed in the placement groove 31. The clamping components include a spring hinge 32 and a movable clamping plate 33. The movable clamping plate 33 is installed on the inner wall of the placement groove 31 through the spring hinge 32. When subjected to external pressure, the movable clamping plate 33 is suitable for flipping downward at a certain angle.

[0035] The inclined support 2 is also provided with a material turning support 22, and the material turning support is provided with a material turning channel 221;

[0036] The conveying hopper 3 is adapted to slide on the first sliding channel 21 and / or the tipping channel 221;

[0037] The lifting device includes a lifting drive motor 41, a first lifting wheel 42, a second lifting wheel 43, and a lifting rope. The lifting drive motor 41 is mounted on the mounting base 1. The first lifting wheel 42 is rotatably mounted on the top of the first sliding channel 21. The first lifting wheel 42 and the second lifting wheel 43 are coaxially arranged. The lifting rope is adapted to be wound around the first lifting wheel 42 and connected to the conveying hopper 3. The movable end of the lifting drive motor 41 is connected to the second lifting wheel 43 through a synchronous belt.

[0038] The lifting drive is adapted to drive the first lifting wheel 42 to rotate so as to move the conveying hopper 3 upward along the first sliding channel 21 to a specific position. When it is in conjunction with the tipping channel 221, the conveying hopper 2 flips over so as to put the material in the placement trough 31 into the smelting furnace.

[0039] Specifically, such as Figure 1-5 As shown, the conveying hopper 3 is also provided with two first sliding wheel sets. The first sliding wheel set includes a first support 51, a first connecting shaft 52 and a first sliding wheel 53. The first support 51 is installed on the conveying hopper 3, the first connecting shaft 52 is installed on the first support 51, and the first sliding wheel 53 is connected to the first connecting shaft 52. The first sliding wheel 53 is slidably fitted in the corresponding first sliding channel 21. The lifting rope is suitable for connecting the first lifting wheel 42 and the first sliding wheel 53. The top of the first sliding channel 21 is also provided with a baffle 211. When the first sliding wheel 53 slides to the predetermined position, it is blocked by the baffle 211.

[0040] Specifically, such as Figure 1-5 As shown, the conveying hopper 3 is also provided with two second sliding wheel sets. The second sliding wheel set includes a second support 61, a second connecting shaft 62 and a second sliding wheel 63. The second support 61 is installed on the conveying hopper 3, the second connecting shaft 62 is installed on the second support 61, and the second sliding wheel 63 is connected to the second connecting shaft 62. The second sliding wheel 63 is suitable for sliding in the first sliding channel 21 and / or the turning channel 221.

[0041] In this embodiment, the first support 51 is a bearing seat, and the second support 61 is a fixed seat.

[0042] Specifically, such as Figure 1-5 As shown, the top of the conveying hopper 3 is provided with an inclined surface 34, and the inclined surface 34 and the placement groove 31 form a certain inclination angle to facilitate the material to slide from the placement groove 31 into the smelting furnace.

[0043] In this embodiment, the inclined surface 34 ensures that the aluminum ingot can smoothly slide from the placement groove 31 onto the inclined surface 34 and roll into the smelting furnace when the conveying hopper 3 tilts and flips, thus accelerating the material conveying process.

[0044] Specifically, such as Figure 1-3 As shown, the conveying hopper 3 is also provided with a sliding door 35, which has a handle 351 for easy gripping. The sliding door 35 is suitable for opening to fill materials into the placement slot 31.

[0045] Specifically, such as Figure 1-3 As shown, the conveying hopper 3 is also provided with a third support 71, which is installed at the bottom of the conveying hopper 3 and has a pushing hole.

[0046] Specifically, such as Figure 5As shown, an infrared sensor is provided in the first sliding channel 21. The infrared sensor is adapted to sense the second sliding wheel 63 and is adapted to be connected to an external controller.

[0047] Specifically, such as Figure 1-5 As shown, an mounting plate 23 is also installed on the inclined bracket 2. An electric push rod 231 is hinged on the mounting plate 23. When the conveying hopper 3 slides to the predetermined position, the infrared sensor senses the second sliding wheel 63 and sends a signal to the external controller. The external controller controls the electric push rod 231 to extend to the push hole 711 on the third support 7, pushing the third support 71 to move so that the second sliding wheel 63 slides into the material turning channel 221.

[0048] In this embodiment, the infrared sensor can be an infrared sensor, which is existing technology. Its structure and implementation principle will not be described in detail in this embodiment. The electric push rod 231 is mounted on the mounting plate 23 through the hinge seat. When the lifting device pulls the conveying hopper 3 to rise, the second sliding wheel 63 also rises with the conveying hopper 3. When the second sliding wheel 63 rises to the predetermined position, it is sensed by the infrared sensor.

[0049] In this invention, when the equipment is in its initial state, the conveying hopper 3 is located at the lowest point of the inclined support 2. The operator opens the sliding door 35 and uses a forklift to lift the pallet containing aluminum ingots and place it into the placement slot 31 of the conveying hopper 3. The forklift places the pallet containing aluminum ingots from top to bottom. The pallet presses down the movable clamp 33 so that the pallet can be placed at the bottom of the placement slot 31. After the pallet passes the movable clamp 33, the movable clamp 33 bounces back to the initial position due to the force of the spring hinge 32, restricting the pallet at the bottom of the placement slot 31. The forklift is then pulled out from the bottom of the placement slot 31.

[0050] After the sliding door 35 is closed, the lifting device starts to work. The lifting drive motor 41 drives the first lifting wheel 42 and the second lifting wheel 43 to rotate through the synchronous belt, thereby driving the lifting rope wrapped on the first lifting wheel 42, so that the conveying hopper 3 moves upward along the first sliding channel 21.

[0051] When the conveying hopper 3 moves upward, it drives the first sliding wheel 53 and the second sliding wheel 63 to move upward. When the first sliding wheel 53 slides to the top of the first sliding channel 21, it is blocked by the baffle 211. At this time, the infrared sensor in the first sliding channel 21 senses the second sliding wheel 63 and sends a signal to the external controller. The external controller controls the electric push rod 231 to move. The electric push rod 231 extends into the push hole 711 on the third support 71. Due to the force of the electric push rod 231, the third support 71 is pushed, which drives the second sliding wheel 63 to slide into the tipping channel 221, so that the conveying hopper 3 flips with the first sliding wheel 53 as the fulcrum. When the conveying hopper 3 flips to a certain extent, the opening of the placement trough 31 faces the external smelting furnace, and the material slides from the placement trough 31 into the smelting furnace.

[0052] After the material feeding is completed, the electric push rod 231 retracts, and the conveying hopper 3 returns to its upright position due to its own gravity. The second sliding wheel 63 slides from the material turning channel 221 to the first sliding channel 21, thus completing one feeding cycle.

[0053] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
