[0002] Inoculation treatment refers to a method of adding a small amount of material (i.e., inoculant) to molten metal during the casting stage of a casting to improve the structure and physical and mechanical properties of the metal. For ductile iron, inoculation treatment plays a decisive role, which can eliminate the tendency of crystallization supercooling, promote graphite spheroidization, reduce intercrystalline segregation, and thus improve the strength, strength and toughness of the casting.

However, when different devices need to be fed, due to the different heights of the devices, and the inclination angle of the conveying pipe cannot be adjusted, it is impossible to meet the optimal feeding position, resulting in easy splashing and loss of the inoculant during the feeding process, thus increasing the production cost, and the conveying pipe is not convenient to store after use, resulting in a large occupied area. Content of the Utility Model

[0004] The utility model provides a device for automatically adding inoculant during pouring, aiming to solve the problem that when different devices need to be fed, due to the different heights of the devices, the inclination angle of the conveying pipe cannot be adjusted.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a ladle flux automatic adding device, including a base 1, support columns 2 are fixedly connected to the four corners of the top of the base 1, a support plate 5 is fixedly connected to the top of the support columns 2, the support plate 5 is U-shaped, a screw feeder 9 is rotatably arranged between the front two support columns 2, the screw feeder 9 can be placed in the support plate 5 when rotated to a vertical state, a storage hopper 4 is arranged in the support plate 5, a plurality of rotating rollers 11 for dispersing the ladle flux are arranged in the storage hopper 4, and a driving assembly for driving the rotating rollers 11 to rotate is arranged on the support plate 5.

[0020] In this embodiment, a pressure weighing device and an electromagnetic valve are arranged in the storage hopper 4. When it is necessary to feed the screw feeder 9 quantitatively, first, an appropriate proportional weight is weighed by the pressure weighing device, and then the valve can be opened through the electromagnetic valve to convey the ladle flux into the screw conveyor 9.

[0021] By rotating the screw feeder 9, the ladle flux can be conveyed into devices at different heights. When the screw feeder 9 is not needed, the screw feeder 9 is rotated to a vertical state for storage, avoiding inconvenience during the movement of the feeding equipment and making the movement more convenient.

[0022] A third motor is arranged at the bottom of the screw feeder 9. By rotating the angle of the screw feeder 9 to adapt to the height of the device, and then the screw feeder 9 rotates under the drive of the motor to evenly convey the ladle flux in the storage hopper 4 into the molten iron.

[0023] Put the ladle flux into the storage hopper 4, and ensure that the rotating rollers 11 and the screw feeder 9 are in normal working conditions. Turn on the driving assembly and the motor of the screw feeder 9 to make the rotating rollers 11 start to rotate to disperse the ladle flux. At the same time, the screw feeder 9 starts to convey the ladle flux into the molten iron. During the pouring process of the molten iron, the ladle flux is evenly added with the iron flow through the screw feeder 9 to achieve the purpose of in-stream inoculation.

[0024] Further, the driving assembly includes a support frame 3, the bottom of the support frame 3 is arranged on the top of the support plate 5, a first motor 12 is arranged on the support frame 3, a first rotating shaft 10 is fixedly connected to the output shaft of the first motor 12, and a plurality of rotating rollers 11 are fixedly connected to the surface of the first rotating shaft 10.

[0025] In this embodiment, the first motor 12 is turned on, and its output shaft starts to rotate, driving the first rotating shaft 10 and the rotating roller 11 fixedly connected to its surface to rotate synchronously. As the rotating roller 11 rotates, they physically disperse the inoculant in the storage hopper 4 to prevent caking or blockage. The dispersed inoculant enters the screw feeder 9 through the outlet at the bottom of the storage hopper 4 via the first hose 7 and is conveyed by the screw feeder 9 into the molten iron pouring system for in-stream inoculation.

During the connection process, it should be ensured that the hose is free of twists, bends, etc. to ensure the smoothness of material transportation.

[0028] Further, a second rotating shaft 14 is rotatably provided between the two front support columns 2. A fixed plate 16 is provided on one side of the support column 2, and a second motor 15 is fixedly connected to the top of the fixed plate 16. One end of the output shaft of the second motor 15 is provided with a speed reducer, and the output shaft of the speed reducer is fixedly connected to one end of the second rotating shaft 14.

[0029] In this embodiment, when it is necessary to drive the second rotating shaft 14 to rotate, the second motor 15 is started. The output shaft of the second motor 15 will drive the speed reducer to rotate, and the speed reducer will reduce the speed and increase the torque through internal mechanisms such as gears or worm gears and then transmit it to the second rotating shaft 14 to make it start to rotate, thereby adjusting the angle of the screw feeder 9 to be applicable to devices of different heights and conveying the inoculant inward.

[0030] Further, universal wheels 17 are fixedly connected to the bottom of the base 1, and a handle 6 is provided on the front side of the base 1.

After moving to the appropriate position, the universal wheels 17 can be locked to add materials.

[0032] Further, an observation mirror 18 is provided on the front side of the storage hopper 4.

[0033] In this embodiment, in order to facilitate the operator to directly observe the material situation inside the storage hopper 4, such as the material stock, flow state, and whether there is caking or blockage, without opening the storage hopper 4 or interrupting the work process.

[0034] Working principle and usage process of the utility model: After the utility model is installed, first, manually push the device to a suitable position. First, start the second motor 15 to drive the screw feeder 9 to rotate to an inclined state to be suitable for conveying into devices at different heights.
