[0029] Example

[0030] Reference Figure 1-Figure 3The utility model discloses a pouring bag feeding wire balling system, which includes: a water receiving platform and a balling platform, the water receiving platform includes a water receiving track 100, the balling platform includes a transfer track 200, the water receiving track 100 is perpendicular to the transfer track 200, a water receiving transfer vehicle 700 reciprocates on the water receiving track 100, and a bag transfer vehicle 800 reciprocates on the transfer track 200; the water receiving platform also includes an electric furnace 300, the electric furnace 300 and the water receiving track 100 are connected to each other. A furnace front roller 310 is arranged in between, and the direction of the furnace front roller 310 is perpendicular to the water receiving track 100. Multiple electric furnaces 300 can be arranged on the side of the water receiving track 100, and a furnace front roller 310 is arranged in front of each electric furnace 300; the spheroidizing platform includes a spheroidizing device 400, a slag removal platform 500 and a residual liquid pouring device 600, and the spheroidizing device 400, the slag removal platform 500 and the residual liquid pouring device 600 are all connected to the transfer track 200 through rollers, and the rollers are perpendicular to the transfer track 200.

[0031] Specifically, the pouring ladle 900 receives molten iron on the furnace front roller 310, and after receiving the molten iron, it is transported to the transition roller 410 by the furnace front transfer vehicle. Through the transition roller 410, the pouring ladle 900 directly enters the spheroidizing device 400, automatically covers the ladle cover and closes the spheroidizing door, and performs spheroidizing wire feeding. After completing spheroidizing wire feeding, the pouring ladle 900 enters the rear-tilting slag removal device 520, and the operator stands on the platform to remove slag. After slag removal, the pouring ladle 900 is transported to the ladle transfer vehicle 800, and the ladle transfer vehicle 800 is lifted and transported to the casting machine turntable, and the ladle transfer vehicle 800 is lowered to complete the ladle action of the pouring ladle 900, and the ladle transfer vehicle 800 exits. The casting machine turntable sends the pouring ladle after slag removal to the casting site for casting, and then transports the empty pouring ladle 900 back to the ladle transfer vehicle 800, and the ladle transfer vehicle 800 sends the empty ladle to the residual liquid pouring device 600 to pour the residual liquid. When the pouring machine turntable receives the pouring ladle 900 after slagging, the empty pouring ladle 900 is also hung on the ladle transfer vehicle 800.

[0032] This process uses the pouring ladle 900 to directly enter the spheroidizing device 400 for wire feeding and spheroidizing. It no longer needs a transfer ladle to convert molten iron, which reduces the equipment execution actions, makes the process simpler, and increases the efficiency of transferring molten iron. It also reduces the temperature drop caused by pouring molten iron from the transfer ladle to the pouring ladle 900, reduces the outlet water temperature of the electric furnace 300, saves the electricity cost of the electric furnace 300, and brings great economic benefits to the foundry.

[0033] In an optional embodiment, an emergency pit 320 is arranged below the furnace front roller conveyor 310 ; a first weighing sensor is also arranged at the bottom of the furnace front roller conveyor 310 .

[0034] Specifically, the emergency pit 320 can be used to receive the leaked molten iron as an emergency safety measure. This design can reduce the danger caused by the leakage of molten iron and provide a safer working environment for the staff. The setting of the emergency pit 320 can prevent the molten iron from flowing directly to the surrounding environment, which helps to avoid possible pollution or damage to the surrounding area. The first weighing sensor at the bottom can accurately weigh the molten iron, thereby achieving accurate control and management of the production process. This helps to ensure the quality and consistency of production. The data provided by the first weighing sensor can be used to monitor the weight and quality of the molten iron. These data can be used to optimize the production process, improve production efficiency and product quality. By accurately weighing the molten iron, the usage and cost of raw materials can be better controlled, which helps to manage the cost and budget in the production process. By monitoring the weight of the molten iron and the data provided by the sensor, any molten iron leakage or abnormal situation can be identified and resolved in time, which helps to avoid production interruptions and possible losses.

[0035] In an optional embodiment, the slag removal platform 500 is provided with a backward tilting slag removal device 520. A slag removal fume hood 510 is fixedly connected to the top of the slag removal platform 500. Wire feeding spheroidization is to roll the ladle with molten iron into the spheroidization station by the transfer roller. The gate of the spheroidization station is closed, and the spheroidization wire feeding device above inserts the pipe containing spheroidizing agent granules vertically and quickly into the molten iron ladle. The spheroidizing agent reacts violently with the high-temperature molten iron, which is equivalent to adding a reinforcing agent to the molten iron. The spheroidized material that does not react fully will float to the surface, which is the so-called slag, and must be manually removed by slag removal.

[0036] Specifically, the backward-tilted slag removal device 520 allows workers to perform slag removal operations in a safe position, and at the same time, the slag removal fume hood 510 helps to remove harmful gases and smoke, thereby improving the safety of the working environment. The backward-tilted slag removal device 520 simplifies the slag removal process and makes it more efficient. Workers can perform slag removal operations more easily and improve production efficiency. The provision of the slag removal fume hood 510 helps to control the diffusion of smoke and harmful gases. This is very important for maintaining good air quality and working environment. The design of the slag removal platform 500 takes into account the comfort and safety of workers. A relatively safe and relatively comfortable working platform is provided, which helps employees to better complete their tasks. The use of the backward-tilted slag removal device 520 may reduce the wear and tear of the equipment because it can more easily handle the slag removal task, reduce the load on the equipment, and extend the life of the equipment. The slag removal fume hood 510 helps to prevent harmful substances from entering the surrounding environment, thereby reducing the impact on the environment and meeting environmental protection standards. The design of the backward-tilted slag removal device 520 may make the slag removal operation easier, reduce the difficulty of operation, and help reduce the training cost and time of operators.

[0037] In an optional embodiment, a cover plate is provided on the water receiving transfer vehicle 700 and the bag transfer vehicle 800 , and the cover plate covers the opening of the pouring bag 900 .

[0038] Specifically, by reducing the heat loss of molten iron, energy consumption can be effectively reduced and the amount of fuel used can be reduced. This helps to improve the energy efficiency of the production process and reduce the burden on the environment. The covering of the cover plate can help maintain the temperature of the molten iron in the casting ladle 900, ensuring that it is kept in a suitable molten state when needed. This helps to ensure the quality and consistency of the molten iron during the production process. By reducing heat loss, the cooling and solidification of the molten iron can be reduced, thereby reducing waste and losses. This helps to improve the utilization rate of raw materials and reduce resource waste.

[0039] In an optional embodiment, a transition roller 410 is arranged between the spheroidizing device 400 and the transfer track 200; a transfer roller is arranged at the bottom of the transition roller 410, wherein the transfer roller has a lifting function, and the transfer roller has a function of changing the transport direction of the transition roller 410.

[0040] Specifically, the provision of the transition roller 410 helps to achieve a smooth transition between the material transfer device and the transfer track 200. This is very important for preventing vibration and damage to materials during the transfer process. The transfer roller has the function of lifting and lowering and changing the direction of transportation, which increases the flexibility of the system. This means that it can adapt to the needs of transportation at different heights, as well as scenarios where the direction needs to be changed, which improves the applicability of the system. The design of the transition roller 410 and the transfer roller helps to achieve an efficient transfer process. The lifting function can adapt to the requirements of transportation at different heights, while the function of changing the direction of transportation can optimize the flow path of the material. The smooth transition and flexible design help to reduce the loss and wear of the material during the transfer process, extend the life of the equipment, and reduce maintenance costs. Smooth transition and system flexibility help to improve the stability and safety of the equipment. This is crucial to prevent accidents and protect the safety of staff.

[0041] Reference Figure 4 A gray iron device 1000 is arranged above the transfer track 200, and the gray iron device 1000 is located between the slag removal platform 500 and the transition roller 410. The gray iron device 1000 and the spheroidizing device 400 do not operate at the same time, but the system can complete the spheroidizing and gray iron processes.

[0042] In an optional embodiment, the gray iron device 1000 includes a feeding platform 1010, to which a vibrating feeder 1030 is fixedly connected; a temporary storage hopper 1020 is fixedly connected to the top of the vibrating feeder 1030. A material storage box is provided below the material outlet of the temporary storage hopper 1020, and a second weighing sensor 1050 is provided at the bottom of the material storage box. A pneumatic gate 1040 is provided at the material outlet of the material storage box, and a chute 1060 is provided below the pneumatic gate 1040, wherein the chute 1060 is used to receive the material in the material storage box.

[0043] Specifically, this series of devices is used for the "gray iron" process. The "gray iron" process requires the addition of granular materials such as catalysts. The above devices are used to achieve quantitative feeding into the ladle. First, a large amount of granular material is added to the temporary storage bucket 1020, and the vibrating feeder and the second weighing sensor 1050 are used to accurately control the material to the material storage box below. When the "gray iron" process is produced, the cylinder gate is opened, and the quantitative material is slid to the casting ladle 900 through the chute 1060. The raw materials are first added to the temporary storage bucket 1020, and the granular materials are orderly transferred to the material box below through the vibrating feeder. The vibrating feeder can accurately control the flow of materials to ensure accurate batching. The second weighing sensor 1050 is used to accurately measure and monitor the weight of the granular material in the temporary storage bucket 1020. This helps to ensure that the amount of material can be accurately controlled in subsequent steps.

[0044] The working principle and beneficial effects of the utility model are:

[0045] By using the pouring ladle 900 to directly feed the wire for spheroidization, the transfer of molten iron is reduced, the heat loss of the molten iron in the pouring ladle 900 is reduced, the energy consumption of the electric furnace 300 is saved, and economic benefits are brought. In addition, the transfer ladle is not used for molten iron transfer, which reduces the execution actions of the equipment, makes the operation process simpler, and makes the transfer of molten iron more efficient. A cover plate is provided on the water transfer vehicle 700 and the hanging ladle transfer vehicle 800. When the pouring ladle 900 is transferred on the vehicle, the cover plate will cover the opening of the pouring ladle 900 to reduce the heat loss of the molten iron in the pouring ladle 900 during the transfer process.
