Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A sealing shell 21 is fixedly assembled on the top of the slide seat 20. A round tube 22 penetrates the top of the inner wall of the sealing shell 21. Rubber plugs 23 are fixedly assembled on the inner walls of both sides of the sealing shell 21. A cleaning rod 24 is provided on the outer wall of the rubber plug 23. Limiting grooves 25 are provided on both sides of the cleaning rod 24. A rubber hose 26 penetrates the bottom of the sealing shell 21. A motor 28 is also fixedly assembled on the outer wall of the slide seat 20. A gear 27 is fixedly assembled on the output shaft of the motor 28. An air inlet 29 is provided on the top of the hollow plate 9, and an air outlet 30 is also provided on the outer wall of the hollow plate 9. Strong magnets 31 are provided on the outer walls of both sides of the slide seat 20, and an electromagnet 32 ​​is fixedly assembled on the inner wall of the movable groove 18.

[0030] In the above structure, through the arrangement of the base 1, the support plate 2, the mold 3, the electromagnetic guide rail 4, the mobile frame 5, the hook 6, the boiler 7, the receiving platform 8, the hollow plate 9, the annular tube 10, the air inlet pipe 14, the air supply pipe 15, the water outlet pipe 16, the sealing shell 21, the round tube 22, the rubber plug 23, the cleaning rod 24, and the limit groove 25 structure, the user can receive the molten iron through the boiler 7 during use of the device. After receiving the molten iron, the molten iron remaining on the top of the boiler 7 can be scraped off by energizing the electromagnet 32 ​​and extending the cleaning rod 24, so as to avoid the residual molten iron from affecting the subsequent casting operation after solidification, and improve the casting quality. When the molten iron is cast into the mold 3, the boiler 7 needs to be hoisted. At this time, the user can fill the annular tube 10 with hot water, so as to ensure that the user reduces the speed of heat loss of the molten iron inside the boiler 7 when hoisting the boiler 7 with the hook 6, and ensure that the molten iron is in liquid state for the user to perform casting operations, thereby improving the user's operating efficiency.

[0031] See also Figure 1 and Figure 2: A controller is fixedly mounted on the top of the hollow plate 9, and the controller is electrically connected to the electromagnet 32. The number of the electromagnets 32 is several, and the several electromagnets 32 are evenly distributed along the inner wall of the movable groove 18. A tooth groove is opened at the bottom of the cleaning rod 24, and the inner wall of the tooth groove is meshed with the outer wall of the gear 27.

[0032] In the above structure, through the set electromagnet 32 ​​and movable groove 18 structure, when a certain electromagnet 32 ​​is energized and adsorbed with the strong magnet 31, the user can control the electromagnet 32 ​​adsorbed with the strong magnet 31 through the controller to cut off the power, and then energize the next electromagnet 32, so that the strong magnet 31 can be adsorbed, thereby achieving the effect of allowing the slide 20 to gradually move along the inner wall of the movable groove 18 to clean the residual molten iron on the top of the boiler 7, thereby ensuring the normal use of the device, and the boiler 7 can also reduce wear and erosion, thereby extending the service life of the boiler 7 and improving the practicality of the device.

[0033] See also Figure 3-Figure 5 The air inlet pipe 14 is connected to the interior of the air outlet hole 30 through the air supply pipe 15, and the air inlet pipe 14 is connected to the interior of the sealed shell 21 through the air inlet hole 29 and the air outlet hole 30.

[0034] In the above structure, by setting the air inlet pipe 14, the air supply pipe 15, and the air outlet hole 30 structure, the cleaning rod 24 can squeeze the gas discharged from the circular tube 22 during the contraction process, so that the air inside the sealing shell 21 enters the air inlet pipe 14 through the hose 26, thereby pressurizing the hot water inside the annular tube 10, thereby accelerating the flow rate of the hot water inside the annular tube 10, making it convenient for the user to replace the hot water that has lost heat inside the annular tube 10, thereby improving the insulation effect of the annular tube 10 on the molten iron inside the boiler 7.

[0035] See also Figure 6 and Figure 7 : After the electromagnet 32 ​​is energized, it attracts the strong magnet 31 with opposite polarities, and the suction force is greater than the elasticity 1N of the tension spring 19, and the outer wall of the slide seat 20 is slidably connected to the inner wall of the movable groove 18.

[0036] In the above structure, the characteristic that the suction force is greater than the elasticity of the tension spring 19 is utilized, so that the electromagnet 32 ​​can absorb the strong magnet 31 when generating magnetism to drive the slide 20 to move, thereby ensuring that the slide 20 moves to allow the cleaning rod 24 to clean the boiler 7, thereby improving the precision matching of the internal components of the device.

[0037] See also Figure 4 : The inner wall of the limiting groove 25 is slidably connected to the outer wall of the rubber plug 23, and after the cleaning rod 24 is moved out, the bottom of the cleaning rod 24 overlaps the top of the boiler 7.

[0038] In the above structure, by setting the cleaning rod 24 structure, the device can not only clean the boiler 7 by extending and moving the cleaning rod 24 during operation, but also allow air to be discharged into the sealed shell 21 by extending the cleaning rod 24. After the cleaning rod 24 is contracted, the extracted air is discharged into the annular tube 10, thereby accelerating the user's hot water replacement efficiency and further improving the practicality of the device.

[0039] See also Figure 1 and Figure 2 An electromagnetic guide rail 4 is disposed on the top of the base 1, a movable frame 5 is disposed on the outer wall of the electromagnetic guide rail 4, and a hook 6 is fixedly mounted on the outer wall of the movable frame 5.

[0040] In the above structure, by setting up the electromagnetic guide rail 4, the movable frame 5, and the hook 6 structure, the user can hoist the boiler 7 through the hook 6 during the use of the device, so as to cooperate with the electromagnetic guide rail 4 and the movable frame 5 to move the hook 6 with the boiler 7 hoisted, so as to achieve the effect of transferring the molten iron to the mold 3 for casting, thereby improving the automation of the device.

[0041] See also Figure 1 The inner wall of the boiler 7 is provided with a temperature sensor, and the outer wall of the boiler 7 is provided with a circular hole, the number of the circular holes is two, and the two circular holes are symmetrically distributed along the outer wall of the boiler 7.

[0042] In the above structure, the circular hole structure is provided so that the hook 6 can pass through the circular hole to complete the lifting operation, thereby ensuring that the user can transfer the boiler 7 to the mold 3 for casting through the hook 6, thereby ensuring the normal progress of the casting operation.

[0043] See also Figure 4 : Both ends of the hose 26 are provided with a one-way air outlet valve, and the connection between the round tube 22 and the sealing shell 21 is provided with a one-way air inlet valve.

[0044] In the above structure, by setting the one-way air outlet valve and the air inlet valve structure, when the cleaning rod 24 is extended, the negative pressure generated inside the sealing shell 21 will not absorb the hot water inside the annular tube 10, and the excess air inside the annular tube 10 can be discharged to the outside of the annular tube 10 through the pressure reducing valve 13, so that the gas circulation and pressure reduction operation can be completed, and the inside of the sealing shell 21 can only extract the outside air through the circular tube 22, thereby ensuring the normal progress of the subsequent pressurization operation.

[0045] See also Figure 4 and Figure 7 The inner wall of the sealing shell 21 and the outer wall of the cleaning rod 24 are both provided with a rubber sealing layer, and the outer wall of the cleaning rod 24 is slidably connected to the inner wall of the sealing shell 21.

[0046] In the above structure, the rubber sealing layer is provided to prevent the air inside the sealing shell 21 from leaking during the operation of the sealing shell 21 and the cleaning rod 24, thereby ensuring the airtightness of the device during the operation, and further ensuring that the hot water inside the annular tube 10 can be fully pushed and quickly discharged to the outside of the annular tube 10.

[0047] A method for using a ferroalloy casting device comprises the following steps:

[0048] S1: First, after the user assembles the device, the molten iron can be transferred to the boiler 7, and then the boiler 7 can be received by the receiving platform 8, and then the molten iron remaining on the top of the boiler 7 can be cleaned by moving the slide 20 and extending the cleaning rod 24, so as to ensure that the subsequent casting operation will not be affected and improve the casting quality. The user can also use the method of filling the inside of the annular tube 10 with hot water to keep the molten iron inside the boiler 7 warm, so as to slow down the speed at which the molten iron loses heat, thereby improving the practicality of the device. When the molten iron needs to be transferred for casting, the user can move the hook 6 by moving the movable frame 5, and at the same time cooperate with the extension of the output shaft of the hydraulic cylinder 12 to make the hook 6 hoist the boiler 7, so as to achieve the effect of facilitating the user to perform casting operations;

[0049] S2: After the casting is completed, the user can retract the cleaning rod 24 to squeeze the air inside the sealing shell 21 and enter the annular tube 10, so that the hot water after use is pressurized by the air after losing heat and is discharged to the outside of the annular tube 10 at a faster flow rate, thereby facilitating the user to replace the hot water, thereby improving the user's working efficiency and the insulation effect of the device on the molten iron.
