[0002] In the industrialized production process of magnesium and its alloy, the molten magnesium liquid needs to be accurately transferred from the smelting furnace to other containers such as crucible, crystallizer, etc. Due to the strong chemical affinity between magnesium metal and air, water and organic matter, magnesium and its alloy are prone to oxidation, combustion and even explosion. Therefore, in the magnesium alloy smelting and casting process, it is necessary to ensure that the molten magnesium alloy cannot be in contact with a large amount of air.

[0003] The traditional method is to realize the transfer through the magnesium liquid transfer pipe, but this method has the risk of magnesium liquid leakage due to the complex connection structure of the transfer pipe. In addition, the magnesium liquid is easy to oxidize and form slag, which may cause the transfer pipe to be blocked, hinder the flow of magnesium liquid, and the blocked magnesium slag is not only difficult to clean, but also increases the maintenance difficulty. These factors jointly affect the final quality of the magnesium product. Therefore, the technical personnel in the field urgently need to develop a device for transferring magnesium alloy.

[0019] The utility model can be explained in detail through the following examples, the purpose of the utility model is to protect all technical improvements in the range of the utility model, and it should be understood in the description of the utility model that the orientation or position relation indicated by terms such as ''up'', ''down'', ''front'', ''back'', ''left'' and ''right'' only corresponds to the drawing of the application, and is for the convenience of describing the utility model, and does not indicate or imply that the indicated device or element must have a particular orientation.

[0020] Example 1, in combination with the attached Figs. 1-3A magnesium alloy pipetting device comprises a handle 2, a crucible 3, a pyramid column 6 and an inlet and outlet pipe 9. The top of the crucible 3 is sealed, and the bottom is provided with the inlet and outlet pipe 9. The molten magnesium alloy can enter and exit the crucible 3 through the inlet and outlet pipe 9, that is, first enters the crucible 3 and then is transferred to a designated position and discharged.

[0021] The top of the crucible 3 is movably inserted with the pyramid column 6.

[0022] It should be noted that the pyramid column 6 is gap-fitted with the top of the crucible 3. When the molten magnesium alloy is contained, the air in the crucible 3 can be discharged from the gap between the two; when the molten magnesium alloy is discharged, air can enter the crucible 3 from the gap.

[0023] In order to smoothly enter and exit the crucible 3, the top of the crucible 3 is provided with air vents 8, which can be multiple and spaced. If the air vent 8 is single, its opening area is not greater than 5% of the area of the top of the crucible 3; if it is multiple, the total opening area is not greater than 5% of the area of the top of the crucible 3, so as to prevent the molten magnesium alloy from contacting with a large amount of air.

[0024] The bottom of the pyramid column 6 is a sharp cone structure, and the diameter of the shaft is greater than the inner diameter of the inlet and outlet pipe 9. The sharp cone structure at the bottom of the pyramid column 6 cooperates with the top of the inlet and outlet pipe 9 to effectively block the inlet and outlet pipe 9, and the molten magnesium alloy can be transferred. After being transferred to a designated position, the inlet and outlet pipe 9 can be opened by pulling up the pyramid column 6 to discharge the molten magnesium alloy.

[0025] The top of the crucible 3 is provided with a handle 2 corresponding to one side of the pyramid column 6, and the crucible 3 can be operated through the handle 2. The device has simple structure, convenient and fast use and high safety.

[0026] Example 2, combined with the attached Figs. 1-2 A magnesium alloy pipetting device, which is different from example 1 in that on the basis of example 1, a positioning pipe 7 is arranged at the position corresponding to the pyramid column 6 at the top of the crucible 3. The pyramid column 6 is movably inserted with the positioning pipe 7. The positioning pipe 7 can guide the pyramid column 6 and prevent the pyramid column 6 from being randomly deflected when it is pulled out. When it is necessary to block the inlet and outlet pipe 9, the pyramid column 6 cannot be quickly aligned with the inlet and outlet pipe 9.

[0027] Example 3, combined with the attached Figs. 1-3 A magnesium alloy pipetting device, which is based on example 1 or 2. The top of the pyramid column 6 is connected with a push-pull rod 1. The push-pull rod 1 has the function of effectively extending the length of the pyramid column 6. In this way, the operator can maintain a certain distance from the molten magnesium alloy, thereby avoiding accidental scalding accidents.

[0028] The push-pull rod 1 is provided with a positioning rod 4. The handle 2 is in inverted U-shaped structure, and two end heads thereof are fastened to the top of the crucible 3, which means that the operator can hold the closed end of the handle 2 when in use, thereby preventing the crucible 3 from being accidentally dropped. One of the rod bodies of the handle 2 is provided with a supporting rod 5 capable of limiting the positioning rod 4, that is, when it is required to keep the feeding and discharging pipe 9 open, the positioning rod 4 can be placed on the top of the supporting rod 5, at this time, the cornered column 6 and the top of the feeding and discharging pipe 9 are in separated state, and the feeding and discharging pipe 9 is in open state, so that the operator does not need to hold and pull the push-pull rod 1 for a long time.

[0029] Further, the supporting rod 5 can be provided with two not shown in the figure, the upper supporting rod 5 can make the cornered column 6 and the top of the feeding and discharging pipe 9 in the separated state, and the lower supporting rod 5 can make the cornered column 6 and the top of the feeding and discharging pipe 9 in the cooperating state, that is, when the positioning rod 4 is located at the bottom of the lower supporting rod 5, the upward movement of the push-pull rod 1 is limited, so that the feeding and discharging pipe 9 is kept closed, the feeding and discharging pipe 9 is prevented from being accidentally opened, the molten magnesium alloy is prevented from being accidentally leaked, and the phenomenon that the operator is accidentally scalded is prevented.

[0030] The part not described in the utility model is the prior art, and for those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, and all changes falling within the meaning and scope of equivalent elements are intended to be included in the utility model.
