Description

Technical Field

[0001] This utility model relates to the field of in-flow incubation funnel technology, and in particular to an in-flow incubation funnel. Background Technology

[0002] During the pouring of molten iron, an inoculant is added to the molten iron in the ladle through a flow funnel device. As the molten iron flows, it plays an inoculating role. This method can effectively control the uniformity of the inoculant distribution in the molten iron, thereby promoting graphitization, reducing the tendency of white iron, improving the morphology and distribution of graphite, increasing the number of eutectic clusters, and refining the matrix structure.

[0003] However, in the existing technology, the in-flow funnel lacks a control device for the amount of inoculated agent added, which makes it unsuitable for different products. The unsuitability of the in-flow funnel makes it impossible to accurately determine the amount of in-flow inoculant added, which can easily lead to problems of adding too much or too little in actual use. Furthermore, the lack of control over the amount added also makes it impossible to control the rate at which the inoculant is added during the pouring of molten iron. If the rate of addition is too fast or too slow, the in-flow inoculation of the molten iron will not be satisfied. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, and therefore the present application is not limited to the specific embodiments disclosed in the following description.

[0023] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides a stream following inoculation funnel, which comprises a stream following funnel 4, and a discharge opening adjusting assembly 5 is fixedly installed at the bottom of the stream following funnel 4.

[0024] The discharge opening adjusting assembly 5 comprises a connecting block 52, a rotating disc 56 and a blocking piece 58, the connecting block 52 is fixedly connected at the bottom of the stream following funnel 4, the rotating disc 56 is rotatably installed in the connecting block 52, the blocking piece 58 is located at the lower surface of the rotating disc 56, the upper surface of the blocking piece 58 is fixedly installed with a butt joint block 59, the butt joint block 59 is slidingly connected in the rotating disc 56, an arc-shaped hole 510 is formed at the joint of the rotating disc 56 and the butt joint block 59, the discharge opening adjusting assembly 5 is installed at the discharge opening of the stream following funnel 4 at the bottom, for adjusting the size of the discharge opening, the discharge opening adjusting assembly 5 is connected with a remote control device through a signal, and the specific adjusting size comprises In use, the stream following inoculant is in the stream following funnel 4, when pouring, the stream following inoculation is started by pressing the switch of the remote control device to open the funnel, and the discharge opening adjusting assembly 5 is controlled through the remote control device, the rotation of the rotating disc 56 will push the butt joint block 59 through the arc-shaped hole 510, so as to change the position of the blocking piece 58, when the blocking piece 58 moves outward, the diameter of the discharge opening will become larger, and when the blocking piece 58 moves inward, the diameter of the discharge opening will become smaller.

[0025] According to Figure 1 and Figure 2As shown, a support plate 2 is movably connected to one side of the flow funnel 4. A limit ring 6 is fixedly installed at the junction of the support plate 2 and the flow funnel 4. The support plate 2 determines the position of the flow funnel 4 through the limit ring 6. The connecting block 52 in the outlet adjustment assembly 5 is fixedly installed at the bottom of the flow funnel 4.

[0026] according to Figure 1 and Figure 2 As shown, the bottom of the support plate 2 is fixedly connected to the cavity 1, and the top of the cavity 1 is movably connected to the pouring cup 3. The pouring cup 3 is located at the bottom of the flow funnel 4. When the sealing plate 58 moves outward, the flow inoculant will pass through the connecting block 52 and flow into the pouring cup 3, and then enter the cavity 1. During this process, the corresponding gear can be selected using a remote control according to the weight of the casting and the approximate pouring time.

[0027] like Figure 3 and Figure 4 As shown, a protrusion 57 is fixedly installed on the edge of the turntable 56, and a notch 511 is opened on the edge of the connecting block 52. The protrusion 57 is located inside the notch 511. The protrusion 57 is used to connect the turntable 56 and the electric cylinder 55. The notch 511 at the edge of the protrusion 57 provides sufficient space for the movement of the protrusion 57, thereby ensuring that the sealing plate 58 can move normally.

[0028] like Figure 3 As shown, an electric cylinder 55 is rotatably connected to the bottom of the protrusion 57, and a positioning block 54 is fixedly connected to the bottom of the electric cylinder 55. The positioning block 54 determines the rotation center of the electric cylinder 55.

[0029] like Figure 3 As shown, a limiting block 53 is fixedly installed on the upper surface of the support plate 2, and a positioning block 54 is rotatably installed on the top of the limiting block 53. When the piston rod of the electric cylinder 55 extends, it will push the turntable 56 to change the position of the sealing plate 58. At the same time, the electric cylinder 55 itself will rotate around the connection point between the positioning block 54 and the limiting block 53 as the center.

[0030] like Figure 3 and Figure 4 As shown, a fixing block 51 is fixedly installed on the upper surface of the support plate 2, and the sealing piece 58 overlaps the upper surface of the fixing block 51. The fixing block 51 is used to determine the position of the entire sealing piece 58. When used in conjunction with the connecting block 52, it can restrict the position and movement path of the turntable 56 and the sealing piece 58.

[0031] The method of use and working principle of this device: The in-flow inoculant is in the in-flow funnel 4. When pouring, press the switch of the remote control device to open the funnel for in-flow inoculant at the beginning of pouring, and control the electric cylinder 55 in the funnel adjustment component 5 through the remote control device.

[0032] When the piston rod of the electric cylinder 55 extends, it pushes the rotating disc 56, which pushes the butt block 59 through the arc-shaped hole 510 to change the position of the blocking piece 58. When the blocking piece 58 moves outward, the diameter of the leakage hole becomes larger; when the blocking piece 58 moves inward, the diameter of the leakage hole becomes smaller, thereby changing the position of the blocking piece 58;

[0033] When the blocking piece 58 moves outward, the stream inoculant flows into the pouring cup 3 through the connecting block 52 and then into the cavity 1. In this process, the corresponding gear is selected according to the weight of the casting and the approximate pouring time by using the remote controller, and the specific size is adjusted, including After pouring, the blocking piece 58 is completely spliced to prevent the inoculant from continuing to be injected.

[0034] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields. However, any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application still fall within the protection scope of the present application.
