Description

Technical Field

[0001] The invention relates to the technical field of melting furnaces, in particular to a material pushing mechanism for feeding materials into a melting furnace. Background Art

[0002] A melting furnace is an industrial equipment specially used for recycling waste materials and melting metal materials such as aluminum ingots. Its core function is to transform solid metal into liquid by heating, so as to facilitate subsequent processing or reuse. This process not only involves the change of the physical state of the metal itself, but also includes the effective use of thermal energy and the improvement of production efficiency. The main components of a melting furnace include the furnace body and heat transfer equipment, among which the furnace body is used to contain the metal raw materials to be melted, while the heat transfer equipment ensures that the heat can be evenly distributed and promotes the rapid melting of the metal.

[0003] The melting furnaces currently on the market face some challenges in practical application, especially in the feeding method. Most traditional feeding methods adopt a tower structure, the so-called "feeding tower". This structure mainly includes several key parts such as a feeding trolley, a feeding frame, a conveying mechanism, a flipping mechanism, and an electrical control system. The specific operation process is to first load the metal raw materials to be melted, such as aluminum ingots, onto the feeding trolley, then lift the trolley to the top of the feeding tower through the conveying mechanism, and finally pour the metal raw materials into the dissolving chamber with the help of the flipping mechanism.

[0004] However, in the traditional tower charging, the metal raw materials fall directly from a high place when they are put into the dissolving chamber. Such impact force can easily damage the furnace material. In particular, long-term repeated impact may cause increased wear of the furnace refractory materials and shorten their service life. And when the metal raw materials fall into the dissolving chamber, they are directly exposed to the high-temperature flame generated by the burner, which will lead to a high burnout rate. Burnout not only means a waste of raw materials, but also increases production costs and may affect the quality of the final product. Summary of the invention

[0016] The present invention has at least the following beneficial effects: (1) This solution preheats the aluminum ingots by setting up a pushing mechanism, especially by using the first pushing assembly to transport the aluminum ingots to the preheating platform. The preheating process can significantly reduce the temperature difference of the aluminum ingots when they enter the melting furnace body, so that the aluminum ingots can be dissolved under more stable conditions. In this way, the aluminum ingots have reached a higher temperature before entering the molten pool, thereby reducing the thermal shock when they directly contact the high-temperature molten pool and effectively reducing damage to the furnace material. In addition, the preheated aluminum ingots are immersed in the molten pool for melting, which not only improves the melting efficiency, but also significantly reduces the burning loss of the aluminum ingots during the melting process, saving raw materials and reducing production costs; (2) This scheme realizes efficient material transportation and preheating by setting up a first pushing assembly and a second pushing assembly. Specifically, the aluminum ingots to be melted are loaded onto a trolley, and the trolley is pulled by a steel wire rope to be transported to the top of the outer frame with the insulation cover opened. At this time, the first oil cylinder is actuated to push the aluminum ingots on the trolley onto the preheating platform for preheating. After the preheating is completed, the trolley returns to its original position and the insulation cover is closed to maintain the temperature of the preheating platform. After a period of time, a new cart of materials is pushed in. At this time, the previous batch of materials has been pushed to the edge of the molten pool, waiting for the second preheating. Subsequently, the preheated materials are pushed into the molten pool and immersed in the molten pool for melting. This series of cyclic operations not only speeds up the dissolution efficiency of the aluminum ingots, but also makes the entire process more continuous and stable, thereby improving production efficiency; (3) This solution sets up a complete electronic control system, using the PLC controller as the main controller and the servo controller to coordinate the operation of each cylinder and motor. In addition, by setting the operation time through the time relay, each component can be accurately controlled to perform corresponding operations according to the predetermined program. This automated control system ensures the continuous and stable operation of the pusher mechanism, greatly improves the automation level of the equipment, reduces the need for manual intervention, reduces labor costs, and also improves the safety and efficiency of production; (4) This solution effectively enhances the safety performance of the equipment by setting up a buffer component. When the trolley suddenly drops, the acceleration sensor will immediately sense the rapid acceleration of the trolley and transmit the signal to the electronic control system. At this time, the electronic control system will control the fourth cylinder to work, apply pressure to the support spring, so that the connecting sleeve lifts one end of the lever, so that the bead engages with the buffer groove, acts as a brake, and reduces the descent speed of the trolley. This can effectively prevent collision accidents caused by the sudden drop of the trolley, protect the equipment from damage, and prevent surrounding workers from being injured, greatly improving the safety of equipment operation.

The electric control system is arranged between the first pushing assembly and the second pushing assembly. The electric control system is provided with an electric box 701, and a PLC controller 702, a servo controller 703 and a time relay 705 are installed inside the electric box 701, which is used for precise automatic control of the pushing mechanism; In some embodiments, see Figure 1 , Figure 7The electric control system includes a temperature sensor 704 and a time relay 705.

[0021] It should be noted that, by setting up a PLC controller 702, a servo controller 703 and a time relay 705 inside the electric box 701, the PLC controller 702 is used as the main controller during use, and then the servo controller 703 is used to control the operation of each oil cylinder and motor, and the time is set in the time relay 705, and each component is accurately controlled to perform corresponding operations, so as to ensure the continuous and stable operation of the pusher mechanism, improve the automation degree of the equipment, and save labor. In actual operation, the time relay 705 is used to set the start and stop time, and the aluminum ingot to be melted is loaded onto the trolley 405. The trolley 405 is pulled by the steel wire rope 410 to the top of the outer frame 501 with the insulation cover 502 opened, and the trolley 405 is lifted by the first oil cylinder 412 to pour the material onto the preheating platform 2 for preheating, and then the trolley 405 is returned and the insulation cover 502 is closed; 20 to 30 minutes later, another car of material is pushed in. At this time, the first car of material has reached the edge of the molten pool and is preheated for the second time. After 20 to 30 minutes, the trolley 405 pushes the material. At this time, the material with a preheating temperature of 500 to 550 degrees is pushed into the molten pool. The temperature of the aluminum liquid in the molten pool is 730 to 750 degrees, and the material is melted by immersion in the molten pool.

[0022] Further explanation, the fixing frame 1 is the basic structure of the whole device, fixing all other components. The preheating platform 2 is used to perform preliminary heating treatment on the aluminum ingot to reduce the thermal shock after it enters the molten pool. The melting furnace body 3 is the furnace that finally melts the preheated aluminum ingot completely.

[0023] The pusher mechanism is responsible for transporting the aluminum ingot from the loading position to the preheating platform and finally pushing it into the melting furnace. The first pusher assembly includes a guide frame 401, a sliding frame 402, a winding roller 406, a guide wheel 409, etc., which realizes the transportation of the aluminum ingot through mechanical movement. The second pusher assembly includes an outer frame 501, a heat preservation cover 502, a second oil cylinder 503, etc., to ensure that the heat loss of the aluminum ingot is minimized during the preheating process.

[0024] The buffer component is designed to reduce the impact force during the pushing process and improve the safety and stability of the system.

[0025] The electronic control system is used to accurately control the actions of the above components and realize automated operation.

[0026] The workflow is as follows: Preparation stage: The aluminum ingot to be melted is placed on the trolley 405 , which is installed at one end of the sliding frame 402 .

[0027] Transport stage: start the drive motor 408 to drive the reducer 407 to work, thereby rotating the winding roller 406. The winding roller 406 pulls the sliding frame 402 and the trolley 405 thereon to move upward along the guide frame 401 through the winding wire rope 410 until reaching the position of the preheating platform 2.

[0028] Preheating stage: The second oil cylinder 503 is used to push the heat preservation cover 502 to open it and expose the preheating platform 2. Then, the first oil cylinder 412 is activated to turn the trolley 405 over and pour the aluminum ingots onto the preheating platform. After unloading, the trolley 405 returns to the initial position and the heat preservation cover 502 is closed to maintain heat.

[0029] Pushing stage: After preheating for a certain period of time, about 20-30 minutes, the third oil cylinder 507 pushes the preheated aluminum ingot into the melting furnace body 3 through the pushing block 505, and the immersion melting process begins.

[0030] Furthermore, in order to ensure the safe operation of the equipment, a buffer component is designed to deal with possible emergencies. The component includes a support frame 601, a fourth oil cylinder 604, a connecting sleeve 605, a support spring 606, etc. When the acceleration sensor 608 detects that the trolley 405 suddenly accelerates, the fourth oil cylinder 604 responds immediately, and through the action of the lever 602 and the card bead 603, it cooperates with the buffer groove 607 to slow down the speed of the trolley 405 to avoid accidents caused by loss of control. The electric control system consists of an electric box 701, a PLC controller 702, a servo controller 703, a time relay 705, etc. The temperature on the preheating platform is monitored by a temperature sensor 704, and the pushing process is accurately controlled according to the set time interval to ensure the automation and efficiency of the entire process.

[0031] The working process and principle of the present invention are as follows: when in use, the aluminum ingot is loaded into the trolley 405, and then the drive motor 408 is used to drive the reducer 407 to work, and then the reducer 407 can drive the winding roller 406 to rotate, and the winding roller 406 is used to wind the wire rope 410, and the wire rope 410 is guided by the guide wheel 409 to pull the fixed head 411 installed at one end of the sliding frame 402, so that the sliding frame 402 is moved toward the top of the guide frame 401 by the pulley 403, and then the trolley 405 carrying the aluminum ingot is driven to move toward the preheating platform 2, and the heat preservation cover 502 installed on the outer frame 501 is pushed by the second oil cylinder 503, so that the heat preservation cover 502 is unfolded, and then the bottom of the trolley 405 is pushed by the first oil cylinder 412, so that the trolley 405 is turned over, and the aluminum ingot is poured onto the preheating platform 2 for preheating, and then the trolley 405 is withdrawn and the heat preservation cover 502 is closed; 20 ~30 minutes later, another car of materials is pushed in. At this time, the first car of materials has been pushed to the edge of the molten pool by the cooperation of the third oil cylinder 507 and the push block 505, and is preheated for the second time. After 20~30 minutes, the trolley 405 pushes the materials. At this time, the materials with a preheating temperature of 500~550 degrees are pushed into the molten pool. The temperature of the aluminum liquid in the molten pool is 730~750 degrees, and the materials are melted by immersion in the molten pool. In the process of pushing the materials up and down by the trolley 405, when the trolley 405 suddenly drops, the acceleration sensor 608 will sense that the trolley 405 accelerates rapidly. At this time, the fourth oil cylinder 604 will work immediately, pressurize the support spring 606, so that the connecting sleeve 605 lifts one end of the lever 602, so that the card bead 603 is engaged with the buffer groove 607, and the trolley 405 that drops sharply is decelerated to prevent the trolley 405 from suddenly colliding and damaging the equipment and accidentally injuring the surrounding staff when it drops sharply.
