Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal technology, and in particular to a novel spheroidizing station. Background Technology
[0002] A spheroidizing station (also known as a spheroidizing treatment station) is a key equipment system in the foundry industry used to produce ductile iron. Its core function is to precisely add spheroidizing agents (such as magnesium, rare earth alloys, etc.) to molten iron at high temperatures, causing the flake graphite in the cast iron to transform into spheroidal graphite, thereby significantly improving the material's strength, toughness, and wear resistance. The spheroidizing treatment process uses a wire feeding method, as shown in patent 202222734121.1. This spheroidizing station includes a spheroidizing ladle, a ladle cover, and a wire feeding mechanism. The spheroidizing ladle has an inlet, and the ladle cover can close at the inlet. The ladle cover is equipped with a guide tube that matches the cored wire. After the cored wire passes through the guide tube, it can extend into the spheroidizing ladle. The ladle cover is also equipped with a smoke outlet pipe. The wire feeding mechanism is used to feed the cored wire into the guide tube. By setting up the wire feeding mechanism, after the ladle cover is closed at the inlet of the spheroidizing ladle, the cored wire is moved towards the guide tube so that the cored wire can enter the spheroidizing ladle. However, the molten iron ladle of the spheroidizing station was fixed outside the frame without being enclosed, causing a large amount of magnesium vapor generated during the spheroidizing process to escape into the air, seriously polluting the air. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of spheroidizing station to solve the problem of serious pollution in the spheroidizing process in the prior art.
[0004] The objective of this utility model is achieved through the following technical solution: A novel spheroidizing station includes a frame, which is a sealed cavity with an opening on one side. A roller conveyor is installed inside the frame, passing through the opening and extending into the interior of the frame. A wire feeder, a guide tube, an electric lifting door device, a dust hood, and an electric lifting device for a cover are installed at the top of the frame. The outlet of the wire feeder is vertically connected to the guide tube. A lifting door is installed at the opening, and the electric lifting door device drives the lifting door to slide up and down along the frame. The dust hood is connected to the interior of the frame. A cover is installed inside the frame, and the electric lifting device for the cover drives the cover to move up and down. The lower part of the guide tube passes through the cover and is slidably connected to the cover.
[0005] Furthermore, the frame is provided with a partition, which is horizontally fixed inside the frame, and there is a gap between the partition and the inner wall of the frame.
[0006] Furthermore, the gap distance is 10-15mm.
[0007] Furthermore, an air inlet is provided above the conduit.
[0008] Furthermore, both the electric lifting device for the lifting door and the electric lifting device for the cover are electric winch structures.
[0009] Furthermore, a motor is fixedly installed inside the dust collector hood, and a rotating drum is located below the motor. The rotating drum is fixedly connected to the output shaft of the motor. A brush is provided on the rotating drum, and an inner ring plate is provided outside the rotating drum. The inner ring plate is sealed to the inner wall of the dust collector hood to form an arc-shaped dust storage bin. A dust inlet is provided at one end of the dust storage bin, and dust filter teeth are provided at the dust inlet. The dust filter teeth extend and are tangential to the rotating drum.
[0010] This utility model has the following advantages: 1. By rationally configuring the roller conveyor, wire feeder, lifting door, and dust removal hood, the molten iron ladle that generates fumes is placed in a closed space, which not only prevents the fumes from directly leaking into the air, but also enables the fumes to be collected quickly and centrally treated, thus solving the environmental pollution problem of the open spheroidizing station. 2. By using pre-set baffles with gaps, the flue gas is prevented from rapidly dispersing into the air, allowing it to be captured by high-speed airflow and accelerating the dust removal effect; 3. By installing brushes and filter teeth inside the dust collector hood, rare components in the dust can be quickly recovered, achieving effective recycling of resources. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] like Figure 1As shown, a novel spherical forming station has a frame 1 that is a closed cavity structure with an opening at the lower right side. A roller conveyor 3 is installed inside the frame 1. The roller conveyor 3 is commercially available and is existing technology. The roller conveyor 3 passes through the opening and extends into the frame 1. A ladle 2 is placed on the roller conveyor 3 for transporting molten iron. A ladle cover 7 matching the ladle 2 is installed above the ladle 2. A wire guide frame 4, a wire feeder 5, a wire guide tube 6, an electric lifting device 10, a dust hood 11, and an electric lifting device 8 for the ladle cover are installed on the top of the frame 1. The wire guide frame 4 is arc-shaped and installed to the left of the wire feeder 5. The wire feeder 5 is existing technology. The outlet of the wire feeder 5 is vertically connected to the wire guide tube 6, allowing the wire feeder 5 to transmit material vertically downwards. The ladle cover 7 has a round hole through which the wire guide tube 6 slides. The frame is equipped with an air inlet 21, which facilitates the discharge of smoke and dust, prevents material accumulation, and facilitates the smooth descent of the wire. The electric lifting device 10 for the lifting door and the electric lifting device 8 for the cover are both electric winch structures, which are existing technologies. A lifting door 9 is provided at the opening. The steel wire rope of the electric lifting device 10 is fixedly connected to the lifting door 9, which drives the lifting door 9 to slide up and down along the frame 1. The lifting door 9 is used to reduce the opening of the frame 1 and prevent smoke and dust from escaping directly from the opening. The electric lifting device 8 for the cover is used to drive the cover 7 to move up and down. Of course, the electric lifting device 10 for the lifting door and the electric lifting device 8 for the cover can also be replaced by other structures such as cylinders, oil cylinders, and electric screws. The dust removal hood 11 is a tubular structure. One end of the dust removal hood 11 is connected to the inside of the frame 1, and the other end of the dust removal hood 11 is equipped with a valve 12, which is connected to an external exhaust fan.
[0017] The dust removal is achieved by directly using an exhaust fan to drive the airflow. However, due to the large space inside the frame 1, the dust from the molten iron ladle is difficult to be carried away by the airflow during actual use. A partition 20 is installed inside the frame 1, which is installed close to the top of the ladle cover 7. The partition 20 is horizontally fixed inside the frame 1, and there is a gap between the partition 20 and the inner wall of the frame 1. The gap distance is 10-15mm. This gap distance reduces the cross-sectional area of the airflow channel, accelerates the gas flow speed, and can quickly carry away the dust.
[0018] Furthermore, the flue gas contains a large amount of magnesium and rare earth elements. Treating it directly as ordinary flue gas would be wasteful. Therefore, a recovery device is installed in the dust collector hood 11 for their collection. Figure 2 , Figure 3As shown, a motor 13 is fixedly installed inside the upper part of the dust collector hood 11. The motor 13 is axially mounted. A rotating drum 14 is provided below the motor 13. The rotating drum 14 is fixedly connected to the output shaft of the motor 13. The motor 13 drives the rotating drum 14 to rotate. A dust-collecting brush 15 is provided on the circumferential surface of the rotating drum 14. An inner ring plate 16 is provided outside the rotating drum 14. The inner ring plate 16 is sealed to the inner wall of the dust collector hood 11 to form an arc-shaped dust storage bin 17. A dust inlet 19 is provided at one end of the dust storage bin 17. A dust filter tooth 18 is provided at the dust inlet 19. The dust filter tooth 18 has a comb structure. The dust filter tooth 18 extends from the dust inlet 19 and is tangential to the rotating drum 14. The dust on the brush is filtered by the dust filter tooth 18 and is thrown into the dust storage bin 17 due to inertia.
[0019] The working principle of this utility model is as follows: The molten iron ladle 2 is placed on the roller conveyor 3 and transported to the frame 1, located below the ladle cover 7. The electric lifting device 10 of the lifting door and the electric lifting device 8 of the ladle cover are activated, so that the lifting door closes the opening of the frame 1 and the ladle cover 7 is fastened to the molten iron ladle 2. Then, the wire feeder 5 is started. The wire is guided by the wire guide frame 4 and then enters the molten iron ladle 2 through the wire guide pipe 6 and the ladle cover 7 under the action of the wire feeder 5. The generated dust is drawn into the dust removal hood 11 through the gap between the partition 20 and the frame 1 for treatment. The motor 13 of the dust removal hood 11 is started, driving the rotating drum 14 and the brush 15 to rotate. The dust is blocked and adsorbed by the brush 15. During the rotation of the brush 15, the dust passes through the dust filter teeth 18. A large amount of dust is scraped off and centrifuged into the dust storage bin 17 for storage. It can be cleaned periodically in the future.
[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
