[0023] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0025] like Figures 1 to 5 As shown, a preferred embodiment of a metal centrifugal flaking machine with multiple liquid outlets of the present invention includes a frame 5, a centrifugal disk 1 arranged at the lower part of the frame 5, and a smelting device 3 arranged at the upper part of the frame 5. The smelting device 3 has a smelting chamber 31, and a plurality of liquid outlets 41 are provided at the bottom of the smelting device 3. The upper end of each liquid outlet hole 41 is connected to the smelting chamber 31, and the lower end of each liquid outlet hole 41 is opposite to the centrifugal disk 1 up and down, and the distance between the lower end of each liquid outlet hole 41 and the axis of the centrifugal disk 1 is different.

[0026] Specifically, the molten metal in the smelting chamber 31 flows into each outlet hole 41. The molten metal flowing out of each outlet hole 41 can smoothly fall onto the centrifugal disk 1. The rotating centrifugal disk 1 causes the molten metal to form strip-shaped thin sheets around the centrifugal disk 1. Because the distance between the lower end of each outlet hole 41 and the axis of the centrifugal disk 1 is different, the molten metal flowing from each outlet hole 41 onto the centrifugal disk 1 is at different radial positions on the centrifugal disk 1, thereby preventing adhesion between the multiple metal sheets processed by the centrifugal tableting machine and ensuring the quality of the metal sheets. Therefore, the metal centrifugal tableting machine with multiple outlet holes of the present invention not only improves tableting efficiency but also ensures tableting quality.

[0027] To facilitate the processing of the smelting device 3, the metal centrifugal flaking machine with multiple liquid outlets in this embodiment also includes a plug 4. The bottom of the smelting device 3 is provided with a mounting hole 32 connected to the smelting chamber 31. The plug 4 is detachably connected to the bottom of the smelting device 3. Each liquid outlet 41 is arranged in the plug 4, and the upper end of each liquid outlet 41 is connected to the mounting hole 32.

[0028] Furthermore, to ensure that the molten metal in the smelting chamber 31 can completely flow to the centrifugal disc 1, a liquid collecting groove 42 is provided in the middle of the upper end of the plug 4 in this embodiment. The cross-sectional profile of the liquid collecting groove 42 gradually decreases from top to bottom. One of the multiple liquid outlet holes 41 is arranged at the lowest point of the liquid collecting groove 42, and the remaining liquid outlet holes 41 are arranged on both sides of the liquid collecting groove 42. In this embodiment, the liquid collecting groove 42 is a tapered groove with the tip facing downward. In other embodiments of the present invention, the liquid collecting groove 42 may be a hemispherical groove.

[0029] There are various ways to implement the detachable connection of the plug 4 to the bottom of the smelting device 3. In this embodiment, the plug 4 is cylindrical and has external threads. The wall of the mounting hole 32 has internal threads, and the plug 4 is threadedly assembled into the mounting hole 32. In other embodiments of the present invention, a flange can be provided at the lower end of the plug 4 and connected to the bottom of the smelting device 3 using screws.

[0030] Furthermore, to facilitate the rotation of the plug 4, in this embodiment, a wrench hole 43 is provided at the lower end of the plug 4. Specifically, the wrench hole 43 is a blind hole with the opening facing downward, and there are two wrench holes 43, which are symmetrically arranged on both sides of the plug 4. When the plug 4 needs to be disassembled, a cylindrical tool such as a screwdriver is inserted into the wrench hole 43 to rotate the plug 4.

[0031] In this embodiment, multiple mounting holes 32 and plugs 4 are provided. Each mounting hole 32 is spaced apart axially around the centrifugal disk 1, and each plug 4 is arranged in a one-to-one correspondence with each mounting hole 32. Providing multiple mounting holes 32 and plugs 4 at the lower end of the smelting device 3 further increases the number of liquid outlets 41 provided by the smelting device 3, thereby further improving the slab production efficiency of the metal centrifugal slab making machine.

[0032] In this embodiment, three plugs 4 are provided, and the three plugs 4 are evenly spaced around the axis of the centrifugal disk 1. In other embodiments of the present invention, the plugs 4 can be provided as two, four or five. The maximum number of plugs 4 provided is determined by the metal sheet formed on the centrifugal disk 1 by two adjacent liquid outlet holes 41 along the circumference of the centrifugal disk 1 does not stick to each other.

[0033] Among them, setting the distance between two adjacent liquid outlet holes 41 to be larger is beneficial to avoiding the adhesion of multiple metal sheets processed by the metal centrifugal flaking machine, but the increase in the distance between two adjacent liquid outlet holes 41 will lead to a reduction in the number of liquid outlet holes 41. Therefore, it is necessary to reasonably set the spacing between adjacent liquid outlet holes 41 according to the characteristics of different metals. In this embodiment, the plug 4 has various specifications. The melting point of silver is 962°C, the melting point of gold is 1063°C, and the melting point of platinum is 1772°C. For metals with lower melting points, the distance between two adjacent liquid outlet holes 41 can be set closer. For metals with higher melting points, the distance between two adjacent liquid outlet holes 41 needs to be set farther. In this embodiment, the plug 4 matching the smelting gold is defined as the first plug 4, and each liquid outlet hole 41 of the first plug 4 is defined. The radius is R1mm, and the distance between the center axes of two adjacent liquid outlet holes 41 is defined as L1, then: L1 ≥ 5mm-2*R1mm, where R1 is set to 0.8mm to 1mm; the plug 4 matching the smelting platinum is defined as the second plug 4, and the radius of each liquid outlet hole 41 of the second plug 4 is defined as R2mm, and the distance between the center axes of two adjacent liquid outlet holes 41 is defined as L2mm, then: L2 ≥ 8mm-2*R2mm, where R2 is set to 0.8mm to 1mm; the plug 4 matching the smelting copper is defined as the third plug 4, and the radius of each liquid outlet hole 41 of the third plug 4 is defined as R3mm, and the distance between the center axes of two adjacent liquid outlet holes 41 is defined as L3, then: L3 ≥ 4mm-2*R3mm, where R3 is set to 0.8mm to 1mm.

[0034] In this embodiment, three liquid outlet holes 41 are provided on the first plug 4 . The three liquid outlet holes 41 are evenly spaced apart, and the distance between two adjacent liquid outlet holes 41 is 9 mm.

[0035] In this embodiment, the centrifugal disc 1 is made of a metal material. Preferably, the centrifugal disc 1 is made of copper or a copper alloy. Existing centrifugal discs 1 are often made of graphite, which is easily worn and requires frequent replacement. Furthermore, multiple metal sheets tend to adhere to the graphite disc. In this embodiment, the centrifugal disc 1 is made of copper or a copper alloy. Copper and copper alloys have better wear resistance, better heat dissipation, and a better cooling effect, which can prevent the adhesion of metal sheets. Furthermore, the copper disc does not need to be frequently replaced, thereby reducing the maintenance and operating costs of the centrifugal device and the processing costs of the metal sheets.

[0036] In this embodiment, in order to facilitate the collection of metal flakes formed by the centrifugal disk 1, the metal centrifugal flaking machine with multiple liquid outlets in this embodiment also includes a flake chamber 2. The centrifugal disk 1 is arranged in the flake chamber 2. The metal flakes thrown off the centrifugal disk 1 fall to the bottom of the flake chamber 2 after colliding with the flake chamber 2, which facilitates the collection of the processed metal flakes.

[0037] In summary, the metal centrifugal flaking machine with multiple liquid outlets of the present invention includes a frame 5, a centrifugal disk 1 arranged at the lower part of the frame 5 and a smelting device 3 arranged at the upper part of the frame 5. The smelting device 3 has a smelting chamber 31, and a plurality of liquid outlets 41 are provided at the bottom of the smelting device 3. The upper end of each liquid outlet 41 is connected to the smelting chamber 31, and the lower end of each liquid outlet 41 is opposite to the centrifugal disk 1 up and down, thereby ensuring that the molten metal flowing out of each liquid outlet 41 can fall smoothly on the centrifugal disk 1. The rotating centrifugal disk 1 will cause the molten metal to form strip-shaped flakes in the circumferential direction of the centrifugal disk 1. Since the distances between the lower ends of each liquid outlet 41 and the axis of the centrifugal disk 1 are different, the radial positions of the molten metal flowing from each liquid outlet 41 to the centrifugal disk 1 are different on the centrifugal disk 1, thereby avoiding adhesion between the multiple metal flakes processed by the centrifugal flaking machine and ensuring the forming quality of the metal flakes.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
