[0032] like Figures 1 to 5 A molten metal storage device includes: a receiving component 1, a conveying pipe 2, a storage component 3, a connecting frame assembly 4, and a driving component 5;
[0033] The receiving assembly 1 includes a receiving bucket 11 and a transition cylinder 12. The transition cylinder 12 rotates relative to the receiving bucket 11 to receive molten metal.
[0034] The storage component 3 includes an annular body 31 and a sealing ring 32. The annular body 31 has a storage slot with a top opening inside. Two guide edges 311 are symmetrically arranged on the top of the annular body 31. The sealing ring 32 is located between the two guide edges 311 and can rotate on the two guide edges 311.
[0035] One end of the conveying pipe 2 is connected to the transition cylinder 12, and the other end is connected to the sealing ring 32;
[0036] The connecting frame assembly 4 includes a ring body 41 and a connecting rod 43. The ring body 41 is located on the outside of the transition cylinder 12. The ring body 41 is an annular groove with a side opening. A retaining ring 42 is provided on the inner side of the ring body 41. The retaining ring 42 blocks the annular groove on the ring body 41 and moves within the ring body 41. One end of the connecting rod 43 is connected to the ring body 41, and the other end is connected to the annular body 31.
[0037] The driving component 5 is located on the outer wall of the annular body 31. The output end of the driving component 5 is provided with a transmission wheel 51. The side wall of the sealing ring 32 is provided with a driven wheel. The transmission wheel 51 is connected to the driven wheel, thereby driving the sealing ring 32 to rotate, and in turn driving the conveying pipe 2 and the transition cylinder 12 to rotate.
[0038] Specifically, such as Figure 1As shown, the molten metal received in the receiving component 1 can be introduced into the annular groove formed by the annular body 31 and the sealing ring 32 through the conveying pipe 2. The two guide edges 311 are used to restrict and guide the sealing ring 32. When the driving component 5 drives the sealing ring 32 to rotate through the transmission wheel 51, the molten metal can be evenly introduced into the annular storage groove, thereby making the molten metal in the storage component 3 evenly distributed. The arrangement of the annular body 31 and the sealing ring 32 can store the molten metal in a closed space, preventing it from contacting the outside air. The connecting rod 43 can support the ring body 41, and thus support the receiving bucket 11. When the sealing ring 32 rotates, it will drive the conveying pipe 2 and the transition cylinder 12 to rotate synchronously.
[0039] By driving the sealing ring 32 to rotate via the driving component 5, the molten metal can be evenly introduced into the annular storage tank of the storage component 3, avoiding the unevenness of molten metal concentration and temperature caused by unidirectional flow in traditional devices, thereby improving the quality stability of the molten metal.
[0040] The storage component 3 includes an annular body 31 and a sealing ring 32, forming a closed storage space, which effectively prevents the molten metal from contacting the outside air, thereby reducing the risk of oxidation and impurity contamination and improving the purity of the molten metal.
[0041] As a preferred embodiment of the above, refer to Figure 2 The receiving component 1 also includes an air inlet pipe 13, which is connected to the ring body 41 and the baffle ring 42 is connected to the transition cylinder 12. It is used to introduce inert gas into the annular groove of the ring body 41 and the transition cylinder 12, so as to mix with the molten metal in the transition cylinder 12. The introduction of inert gas can effectively remove impurities and oxides in the molten metal, thereby purifying the molten metal and improving its purity.
[0042] The intake pipe 13 is equipped with a regulating valve 131, which is used to adjust the flow rate of inert gas. This allows for precise matching of actual needs, thereby reducing waste of inert gas, lowering operating costs, and improving the economic efficiency of the equipment.
[0043] During casting, air bubbles will float in the molten metal within the annular body 31. To further improve the effect of air bubbles in adsorbing impurities, the following methods can be used: Figure 3 , Figure 4 The structure shown:
[0044] In this embodiment, a push plate 33 is provided at the bottom of the sealing ring 32. Along the rotation direction of the sealing ring 32, the working surface of the push plate 33 is inclined away from the axis of the annular body 31. Multiple stirring rods 34 are provided at the bottom of the push plate 33. A collection chamber 312 for collecting scum is provided on the outer wall of the annular body 31. When the sealing ring 32 rotates, the push plate 33 and the stirring rods 34 rotate synchronously. The bottom of the push plate 33 and the stirring rods 34 are both located in the molten metal. The stirring rods 34 agitate the molten metal, increasing the range of bubble movement and improving its adsorption effect. The push plate 33 moves the scum on the surface of the liquid. The working surface of 3 is inclined, so the pusher plate 33 will push the scum towards the inner wall of the storage tank, and the pusher plate 33 will push the scum to move in a circular motion. When the scum moves to the position of the collection chamber 312, the scum will overflow into the collection chamber 312, thereby realizing the collection of scum. It should be noted that, due to the poor fluidity of the molten metal, the molten metal will only accumulate near the pusher plate 33, and its height will be higher than the liquid level of the static molten metal. This makes it easy for the scum to overflow into the collection chamber 312. When there is a lot of scum collected in the collection chamber 312, the collection chamber 312 can be opened to discharge the scum.
[0045] Meanwhile, the stirring rod 34 further enhances the stirring effect of the molten metal by rotating, eliminating the temperature gradient on the liquid surface. This flow can improve the concentration and temperature distribution of the molten metal, making it more uniform, thereby improving the quality stability of the molten metal.
[0046] As a preferred embodiment of the above, the bottom of the annular body 31 is provided with a plurality of curved tubes 313 for the molten metal inside the annular body 31 to be discharged into the crystallizer. Specifically, the structural design of the curved tubes 313 can appropriately buffer the flow rate of the molten metal, reduce the impact of high flow rate on the inner wall of the crystallizer, and extend the service life of the crystallizer.
[0047] In this embodiment, reference Figure 5 The inner wall of the conveying pipe 2 is provided with a spiral blade 21 for turning the molten metal over. When the sealing ring 32 rotates, it will drive the conveying pipe 2 to rotate synchronously. The input end of the conveying pipe 2 remains stationary, so that the receiving component 1 can receive the molten metal in a fixed position. The spiral blade 21 in the conveying pipe 2 can turn and agitate the molten metal flowing through the conveying pipe 2, so that the inert gas in the molten metal can adsorb impurities more efficiently and comprehensively, thereby enhancing the purification effect and improving the quality of the molten metal.
[0048] The inner wall of the annular body 31 is provided with a high-temperature resistant coating (not shown) to prevent the molten metal from corroding and adhering to the inner wall of the annular body 31, making it easier to clean and maintain, and extending the service life of the device.
[0049] As a preferred embodiment of the above, the bottom of the sealing ring 32 is also provided with a heat-insulating cover plate (not shown) to reduce the heat loss inside the ring body 31, save energy, and reduce costs.
[0050] In this embodiment, the driving component 5 is a servo motor. The servo motor is connected to the sealing ring 32 through a variable speed gear. The servo motor, in conjunction with the variable speed gear, can achieve precise adjustment of the rotation speed of the sealing ring 32 to adapt to the storage and mixing requirements of different molten metals. The driving component 5 can be the motor in this embodiment or other transmission components, all of which are within the protection scope of this application.
[0051] The outer side of the annular body 31 is equipped with a temperature monitoring device and a concentration detection device (not shown) to monitor the temperature and concentration changes of the molten metal in real time and output monitoring data. Through data output, abnormal temperature or concentration can be detected in a timely manner, which makes it convenient for operators to adjust process parameters and ensure the quality of molten metal. The detection device is linked with the automatic control system to realize intelligent adjustment and improve the operating efficiency and reliability of the equipment.
[0052] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
