Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary devices for aluminum melting furnaces, and more specifically, to a waste aluminum adaptive feeding control device. Background Art

[0002] Under the general trend of recycling metal resources, the recycling of waste aluminum has become an important way to save resources and reduce energy consumption. And in the process of waste aluminum regeneration, a key link is to efficiently and accurately feed and melt waste aluminum, and currently, waste aluminum feeding control devices are mostly used.

[0003] Regarding forging processing devices, there are many existing technologies, for example:

[0004] Chinese Patent Publication No. CN209820146U discloses an aluminum melting furnace feeding device, including a furnace body, a protective cover, a conveying device, and a control module. The furnace body is a hollow cylinder, and there is a feeding port on the furnace body. There is a chute on the feeding port, and there is also a top cover on the furnace body. The top cover is slidably matched with the chute. There is a cylindrical protrusion on the top cover. A first servo motor is fixedly installed on the right side of the furnace body. There is a crank on the first output shaft of the first servo motor. The crank is rotatably connected to the first output shaft. There is a connecting rod on the crank. The crank is rotatably connected to the connecting rod. The connecting rod is rotatably connected to the cylindrical protrusion of the top cover. The protective cover is fixedly installed above the furnace body. There is a feeding port on the left side of the top of the protective cover. The conveying device is fixedly installed inside the protective cover, below the feeding port and above the furnace body. The control module is fixedly installed inside the top of the protective cover, above the end of the transmission device.

[0005] However, in the actual use process, there are still some problems:

[0006] 1. At present, during the use of traditional feeding control devices, the weight of waste aluminum cannot be accurately measured. Once too much waste aluminum is put into the melting furnace, exceeding the effective accommodation and melting load of the melting furnace, it is very easy to cause the overflow of molten aluminum. The overflow of molten aluminum will not only cause serious damage to surrounding equipment, trigger equipment failures, increase maintenance costs, but also may lead to production interruptions, greatly affecting production efficiency;

[0007] 2. During the intermediate feeding process of the melting furnace operation, due to the lack of an effective feeding guiding and buffering mechanism, when waste aluminum is put into the melting furnace, it often directly drops onto the molten aluminum surface in the melting furnace with a large impact force. Such a violent impact is very likely to cause the splashing of molten aluminum. The high-temperature molten aluminum splashes out, posing a great threat to the personal safety of on-site operators, there are serious safety risks such as scalding. At the same time, the splashed molten aluminum cannot be fully utilized, resulting in waste of raw materials and increasing production costs invisibly.

[0008] In view of this, we propose an adaptive feeding control device for waste aluminum. Summary of the Invention

[0009] The purpose of the present invention is to provide an adaptive feeding control device for waste aluminum to solve the problems raised in the above-mentioned background technology.

[0010] To achieve the above object, the present invention aims to provide an adaptive feeding control device for waste aluminum, including a heat preservation box and a conveying component. A melting furnace is arranged inside the heat preservation box. The melting furnace is cylindrical, and its upper and lower diameters are in a contracting shape from the bottom upwards. The conveying component includes a waste material box and a conveyor belt. A waste material inlet is arranged at the top of the heat preservation box. An electric slide rail is arranged below the waste material inlet. A quantitative component is arranged on the surface of the electric slide rail. The waste aluminum conveyed by the conveyor belt enters the quantitative component through the waste material inlet for quantitative feeding. A sealing component is arranged at the top of the melting furnace. In the natural state, the sealing component is used to seal the top of the melting furnace so that the melting furnace is in a sealed state during melting. When feeding the inside of the melting furnace is required, the quantitative component approaches the melting furnace to automatically open the sealing component. A stirring component is arranged at the bottom of the sealing component, and the stirring component is used to stir and mix the molten aluminum.

[0011] As a further improvement of this technical solution, the quantitative component includes a box body arranged on the surface of the electric slide rail. A partition is arranged inside the box body. A pressure sensor is arranged between the box body and the partition, and the weight of the waste aluminum falling on the surface of the partition is measured in real time.

[0012] As a further improvement of this technical solution, a support rod is arranged at the end of the box body. A baffle is rotatably arranged on the surface of the support rod. A torsion spring is arranged on the surface of the support rod, and both ends of the torsion spring are respectively fixed on the side walls of the box body and the baffle.

[0013] As a further improvement of this technical solution, a cylinder is arranged on the side wall of the box body. The piston rod at the end of the cylinder penetrates through the box body and a push plate is arranged at the end. When the push plate moves horizontally, it pushes the waste aluminum on the surface of the partition to squeeze the baffle to make it rotate.

[0014] As a further improvement of this technical solution, the sealing component includes a sealing plate arranged at the top of the melting furnace. A pull rope is arranged at the top of the sealing plate, and the free end of the pull rope is fixed at the end of the box body.

[0015] As a further improvement of this technical solution, a fixed pulley is arranged above the sealing plate, and the pull rope fits with the top of the fixed pulley when moving.

[0016] As a further improvement of this technical solution, cylindrical columns are arranged on the surface of the sealing plate. The cylindrical columns are arranged in an annular array on the surface of the sealing plate. A sliding rod is slidably arranged inside the cylindrical column. A compression spring is arranged between the cylindrical column and the sliding rod. An arc-shaped plate is arranged at the top of the sliding rod, and the surface of the arc-shaped plate is in a slope shape.

[0017] As a further improvement of the technical solution, the diameter of the arc plate is adapted to the top of the furnace, and the diameter of the sealing plate is smaller than that of the arc plate.

[0018] As a further improvement of the technical solution, the stirring assembly includes a circular guide rail provided at the bottom of the sealing plate. A moving block is provided on the surface of the circular guide rail. A servo motor is provided on the side wall of the moving block. The servo motor penetrates through the moving block and a friction wheel is provided at the end. The friction wheel is in contact with the bottom of the circular guide rail. The output shaft of the servo motor drives the friction wheel to rotate so that the moving block moves on the surface of the circular guide rail. A stirring rod is provided below the moving block.

[0019] As a further improvement of the technical solution, a bearing is provided between the moving block and the stirring rod. Auxiliary rods are provided on the surface of the stirring rod, and the auxiliary rods are claw-shaped.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In the waste aluminum adaptive feeding control device, when the waste aluminum is input above the waste material inlet through the conveyor belt and falls into the interior of the box body, since a pressure sensor is provided at the bottom of the partition board, the weight of the waste aluminum is measured by the pressure sensor, and the electric slide rail is controlled to drive the box body to move to the opening at the top of the furnace and input the waste aluminum, so as to accurately calculate the feeding of the molten material.

[0022] 2. In the waste aluminum adaptive feeding control device, when the sealing plate moves downward in the vertical direction, the sealing plate drives the arc plate to move downward. When the waste aluminum is discharged, an impact force is applied to the surface of the arc plate. The sliding rod provided at the bottom of the arc plate slides on the inner wall of the cylinder and squeezes the compression spring, thereby buffering the impact force of the falling waste aluminum. The waste aluminum slowly moves downward along the slope surface of the arc plate, thereby reducing the splashing of molten aluminum when the waste aluminum falls into the furnace, improving the safety of the molten aluminum operation, and at the same time avoiding the waste caused by the splashing of molten aluminum.

[0023] 3. In the waste aluminum adaptive feeding control device, by controlling the output shaft of the servo motor to drive the friction wheel provided at the end to rotate, the friction between the friction wheel and the bottom of the circular guide rail drives the moving block to move on the surface of the circular guide rail. The moving block moves in a circular motion. The stirring rod provided below the moving block drives the auxiliary rod to move. The stirring area is increased by the auxiliary rod, enhancing the heat convection in the furnace and improving the thermal efficiency of the furnace. At the same time, in order to avoid direct collision with the unmelted waste aluminum during the stirring process, a bearing is provided between the moving block and the stirring rod. When the auxiliary rod is collided, it rotates at the bottom of the bearing, reducing the external impact force, thereby increasing the service life of the auxiliary rod. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0038] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0039] The purpose of this embodiment is to provide a waste aluminum adaptive feeding control device. Refer to Figures 1 - 7 As shown in the figure, it includes a heat preservation box 100 and a conveying assembly 200. Inside the heat preservation box 100, there is a melting furnace 101. The melting furnace 101 is a cylinder, and its upper and lower diameters are in a contracted shape from the bottom upwards. The conveying assembly 200 includes a waste material box 201 and a conveyor belt 202. There is a waste material inlet 102 at the top of the heat preservation box 100. Below the waste material inlet 102, there is an electric slide rail 103. The surface of the electric slide rail 103 is provided with a quantitative assembly 300. The waste aluminum conveyed by the conveyor belt 202 enters the quantitative assembly 300 through the waste material inlet 102 for quantitative feeding. There is a sealing assembly 400 at the top of the melting furnace 101. In the natural state, the sealing assembly 400 is used to seal the top of the melting furnace 101, so that the melting furnace 101 is in a sealed state when melting materials. When it is necessary to add materials to the inside of the melting furnace 101, the quantitative assembly 300 approaches the melting furnace 101 to automatically open the sealing assembly 400. There is a stirring assembly 500 at the bottom of the sealing assembly 400. The stirring assembly 500 is used to stir and mix the molten aluminum.

[0040] During the process of waste aluminum recycling and remelting, due to the different sizes of waste aluminum and the limited volume of the melting furnace 101, it is necessary to calculate the weight of the waste aluminum to be melted, so as to avoid the overflow of waste aluminum when it is heated and melted due to excessive waste aluminum. Therefore, the quantitative assembly 300 includes a box body 301 provided on the surface of the electric slide rail 103. Inside the box body 301, there is a partition plate 302. A pressure sensor 303 is provided between the box body 301 and the partition plate 302. The weight of the waste aluminum falling on the surface of the partition plate 302 is measured in real time. When the waste aluminum is input above the waste material inlet 102 through the conveyor belt 202 and falls into the box body 301, since there is a pressure sensor 303 at the bottom of the partition plate 302, the weight of the waste aluminum is measured by the pressure sensor 303, and the electric slide rail 103 is controlled to drive the box body 301 to move to the opening at the top of the melting furnace 101 and input the waste aluminum, so as to accurately calculate the feeding of the melting materials, avoid excessive melting materials from overflowing, and improve the safety of the operation.

[0041] Considering that when cutting waste aluminum, it is necessary for operators to carry it, resulting in increased labor intensity of the operators. Therefore, a support rod 304 is provided at the end of the box body 301. A baffle 305 is rotatably provided on the surface of the support rod 304. A torsion spring 306 is provided on the surface of the support rod 304. The two ends of the torsion spring 306 are respectively fixed on the side walls of the box body 301 and the baffle 305. A cylinder 307 is provided on the side wall of the box body 301. The piston rod at the end of the cylinder 307 penetrates through the box body 301 and a push plate 308 is provided at the end. When the push plate 308 moves horizontally, it pushes the waste aluminum on the surface of the partition plate 302 to squeeze the baffle 305 to make it rotate. When the box body 301 moves to the opening at the top of the melting furnace 101, by controlling the piston rod at the end of the cylinder 307 to drive the push plate 308 to move horizontally, the push plate 308 pushes the waste aluminum falling on the surface of the partition plate 302 during the moving process. The waste aluminum squeezes the side wall of the baffle 305 during the moving process, and the baffle 305 rotates to form an opening on the surface of the support rod 304. The waste aluminum falls into the interior of the melting furnace 101 from the opening, thus realizing automatic blanking and reducing the labor intensity of the operators.

[0042] Considering that during the melting process of waste aluminum in the melting furnace, in order to facilitate the addition of waste aluminum midway. Therefore, the sealing assembly 400 includes a sealing plate 401 provided on the top of the melting furnace 101. A pull rope 402 is provided on the top of the sealing plate 401. The free end of the pull rope 402 is fixed at the end of the box body 301. A fixed pulley 104 is provided above the sealing plate 401. When the pull rope 402 moves, it fits on the top of the fixed pulley 104. By providing the sealing plate 401 on the top of the melting furnace 101, when the interior of the melting furnace 101 is heated to heat the waste aluminum, the heat is sealed by the sealing plate 401 to ensure the temperature inside the melting furnace 101, thereby improving the melting efficiency of the waste aluminum. When it is necessary to add waste aluminum midway, by controlling the electric slide rail 103 to drive the box body 301 close to the top of the melting furnace 101. When the box body 301 moves, it drives the pull rope 402 to move on the top of the fixed pulley 104. The sealing plate 401 provided at the end of the pull rope 402 moves downward in the vertical direction, so that an opening is formed between the sealing plate 401 and the melting furnace 101 to facilitate the waste aluminum to be added to the interior of the melting furnace 101. When the addition is completed, control the electric slide rail 103 to drive the box body 301 away from the top of the melting furnace 101, so that the sealing plate 401 moves upward in the vertical direction under the tension of the pull rope 402 to automatically seal the top of the melting furnace 101, thereby improving the practicability of the device.

[0043] Considering that when adding scrap aluminum into the furnace, due to the heavy weight of the scrap aluminum, the molten aluminum splashes outside the furnace 101 during the feeding process of the scrap aluminum, causing potential safety hazards and waste of molten aluminum. Therefore, a cylinder 403 is provided on the surface of the sealing plate 401. The cylinders 403 are arranged in a circular array on the surface of the sealing plate 401. A sliding rod 404 is slidably arranged on the inner wall of the cylinder 403. A compression spring 405 is arranged between the cylinder 403 and the sliding rod 404. An arc-shaped plate 406 is provided at the top of the sliding rod 404. The surface of the arc-shaped plate 406 is sloped. The diameter of the arc-shaped plate 406 is adapted to the top of the furnace 101. The diameter of the sealing plate 401 is smaller than that of the arc-shaped plate 406. When the sealing plate 401 moves downward in the vertical direction, the sealing plate 401 drives the arc-shaped plate 406 to move downward. When the scrap aluminum is fed, an impact force is applied to the surface of the arc-shaped plate 406. The sliding rod 404 provided at the bottom of the arc-shaped plate 406 slides on the inner wall of the cylinder 403 and compresses the compression spring 405, thereby buffering the impact force of the falling scrap aluminum. The scrap aluminum slowly moves downward along the sloped surface of the arc-shaped plate 406, thereby reducing the splashing of molten aluminum when the scrap aluminum falls into the furnace 101, improving the safety of the molten aluminum operation, and at the same time avoiding the waste caused by the splashing of molten aluminum.

[0044] During the melting process of the scrap aluminum, in order to accelerate the melting of the scrap aluminum, therefore, the stirring assembly 500 includes a circular guide rail 501 provided at the bottom of the sealing plate 401. A moving block 502 is provided on the surface of the circular guide rail 501. A servo motor 503 is provided on the side wall of the moving block 502. The servo motor 503 penetrates through the moving block 502 and a friction wheel is provided at the end. The friction wheel is in contact with the bottom of the circular guide rail 501. The output shaft of the servo motor 503 drives the friction wheel to rotate, causing the moving block 502 to move on the surface of the circular guide rail 501. A stirring rod 505 is provided below the moving block 502. A bearing 504 is provided between the moving block 502 and the stirring rod 505. An auxiliary rod 506 is provided on the surface of the stirring rod 505. The auxiliary rod 506 is claw-shaped. During the heating process of the furnace 101, when the scrap aluminum is in a molten state, control the output shaft of the servo motor 503 to drive the friction wheel provided at the end to rotate. The friction between the friction wheel and the bottom of the circular guide rail 501 drives the moving block 502 to move on the surface of the circular guide rail 501. The moving block 502 moves in a circular motion. The stirring rod 505 provided below the moving block 502 stirs the molten aluminum to make it fully melt. The stirring rod 505 drives the auxiliary rod 506 to move during the movement, increasing the stirring area through the auxiliary rod 506, enhancing the heat convection in the furnace 101, making the heat transfer faster and more uniform in the molten aluminum, reducing the accumulation of heat in local areas, improving the thermal efficiency of the furnace 101, reducing energy consumption. At the same time, in order to avoid direct collision with the un-melted scrap aluminum during the stirring process, a bearing 504 is provided between the moving block 502 and the stirring rod 505. When the auxiliary rod 506 is impacted, it rotates at the bottom of the bearing 504, reducing the external impact force, thereby increasing the service life of the auxiliary rod 506.

[0045] During specific use, when scrap aluminum is input above the waste material inlet 102 through the conveyor belt 202 and falls into the interior of the box body 301, since a pressure sensor 303 is provided at the bottom of the partition plate 302, the weight of the scrap aluminum is measured by the pressure sensor 303, and the electric slide rail 103 is controlled to drive the box body 301 to move to the opening at the top of the melting furnace 101 and input the scrap aluminum, so as to accurately calculate the feeding of the molten material;

[0046] By controlling the piston rod at the end of the air cylinder 307 to drive the push plate 308 to move horizontally, the push plate 308 pushes the scrap aluminum falling on the surface of the partition plate 302 during the movement. The scrap aluminum squeezes the side wall of the baffle 305 during the movement, and the baffle 305 rotates to form an opening on the surface of the support rod 304, and the scrap aluminum falls into the interior of the melting furnace 101 from the opening, thus realizing automatic feeding and reducing the labor intensity of the operators;

[0047] When the interior of the melting furnace 101 is heated to heat the scrap aluminum, the heat is sealed by the sealing plate 401 to ensure the temperature inside the melting furnace 101, thereby improving the melting efficiency of the scrap aluminum. When it is necessary to add scrap aluminum midway, the electric slide rail 103 is controlled to drive the box body 301 close to the top of the melting furnace 101. When the box body 301 moves, it drives the pull rope 402 to move on the top of the fixed pulley 104, and the sealing plate 401 provided at the end of the pull rope 402 moves downward in the vertical direction, so that an opening is formed between the sealing plate 401 and the melting furnace 101 to facilitate the scrap aluminum to be added inside the melting furnace 101. When the addition is completed, the electric slide rail 103 is controlled to drive the box body 301 away from the top of the melting furnace 101, so that the sealing plate 401 moves upward in the vertical direction under the tension of the pull rope 402 to automatically seal the top of the melting furnace 101, thereby improving the practicability of the device.

[0048] When the sealing plate 401 moves downward in the vertical direction, the sealing plate 401 drives the arc plate 406 to move downward. When the scrap aluminum is fed, an impact force is applied to the surface of the arc plate 406. The slide rod 404 provided at the bottom of the arc plate 406 slides on the inner wall of the cylinder 403 and squeezes the compression spring 405, thereby buffering the impact force of the falling scrap aluminum. The scrap aluminum slowly moves downward along the slope surface of the arc plate 406, so as to reduce the splashing of molten aluminum when the scrap aluminum falls into the interior of the melting furnace 101, improve the safety of the molten aluminum operation, and avoid the waste caused by the splashing of molten aluminum at the same time;

[0049] Control the output shaft of the servo motor 503 to drive the friction wheel provided at the end to rotate. The friction wheel drives the moving block 502 to move on the surface of the circular guide rail 501 by friction with the bottom of the circular guide rail 501. The moving block 502 moves in a circular motion. The stirring rod 505 provided below the moving block 502 stirs the molten aluminum to make it fully melt. During the movement of the stirring rod 505, the auxiliary rod 506 is driven to move, and the stirring area is increased through the auxiliary rod 506, enhancing the heat convection in the furnace 101, making the heat transfer faster and more uniform in the molten aluminum, reducing the accumulation of heat in local areas, improving the thermal efficiency of the furnace 101, and reducing energy consumption. At the same time, in order to avoid direct collision with the unmelted waste aluminum during the stirring process, a bearing 504 is provided between the moving block 502 and the stirring rod 505. When the auxiliary rod 506 is impacted, it rotates at the bottom of the bearing 504 to reduce the external impact force, thereby increasing the service life of the auxiliary rod 506.
