[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0031] In order to facilitate understanding of the technical solution of the present application, the shortcomings of the existing melting furnace are explained here: during the melting process of the existing melting furnace, the raw materials inside may be heated unevenly, so that the raw materials at the bottom of the melting furnace are in a molten state, while the raw materials at the top have not yet begun to melt, resulting in a long melting time for the raw materials. At present, in order to make the raw materials in the melting furnace heated more evenly, a stirring mechanism is usually set in the melting furnace, but the setting of the stirring mechanism makes it difficult to clean the inside of the melting furnace.

[0032] like Figures 1 to 3 As shown, an embodiment of the present application provides an ingot casting system 10, including a feeding device 100, a melting furnace 200, a stirring device 300 and an ingot casting machine 400. The melting furnace 200 is arranged downstream of the feeding device 100, so as to obtain the raw materials conveyed by the feeding device 100, and the stirring device 300 includes a stirring mechanism 310 that can reciprocate along a first direction. The stirring mechanism 310 can enter and exit the melting furnace 200 during the reciprocating movement along the first direction to stir the raw materials in the melting furnace 200. The ingot casting machine 400 is arranged downstream of the melting furnace 200 to cast the product after smelting.

[0033] The loading device 100 conveys the raw materials into the melting furnace 200, and the melting furnace 200 melts the raw materials. During the melting process, the stirring mechanism 310 can enter the melting furnace 200 for stirring to shorten the melting time and improve the melting and production efficiency. After the melting is completed, the smelted product is conveyed to the ingot casting machine 400 for ingot casting.

[0034] Furthermore, the ingot casting system includes at least two feeding devices 100, at least two melting furnaces 200 and at least two stirring devices 300, and at least the feeding devices 100, at least two melting furnaces 200 and at least two stirring devices 300 are arranged in a one-to-one correspondence. Figure 1 In the illustrated embodiment, there are two loading devices 100 , two melting furnaces 200 and two stirring devices 300 .

[0035] With the above-mentioned ingot casting system, the stirring mechanism 310 can enter the melting furnace 200 to stir during the smelting process, so that the raw materials in the melting furnace 200 are heated more evenly, the smelting time is shortened, and the smelting efficiency is improved. At the same time, the stirring mechanism 310 can be moved out of the melting furnace 200, so as to facilitate the cleaning of the melting furnace 200 and the stirring mechanism 310, shorten the maintenance time, and further improve the production efficiency. In addition, the ingot casting system includes at least two feeding devices 100, at least two melting furnaces 200 and at least two stirring devices 300, which can further improve the smelting efficiency and thus improve the production efficiency.

[0036] It should be noted that, in this embodiment, the raw material is crude selenium. In other embodiments, the raw material may also be other substances, which are not limited here.

[0037] In one embodiment, the loading device 100 includes a loading machine 110 , which is reciprocatably disposed on one side of the melting furnace 200 , and the loading machine 110 can pass through a loading position and a staggered position during the reciprocating movement.

[0038] When the loader 110 is located at the loading position, the discharge end of the loader 110 is connected to the feed port 210 of the melting furnace 200, so that raw materials are input into the melting furnace 200; when the loader 110 is located at the staggered position, the discharge end of the loader 110 is staggered with the feed port 210 of the melting furnace 200, so as to facilitate the stirring mechanism 310 to enter the melting furnace 200 through the feed port 210.

[0039] Optionally, the loader 110 adopts spiral loading or conveyor belt loading.

[0040] In one embodiment, the feeding device 100 also includes a collecting hopper 120, which is arranged upstream of the melting furnace 200 and is used to receive and temporarily store raw materials. When the loader 110 moves to the feeding position, the feed end of the loader 110 is connected to the discharge port of the collecting hopper 120, thereby transporting the raw materials in the collecting hopper 120 to the melting furnace 200.

[0041] It should be noted that the collecting hopper 120 can be fixed on one side of the melting furnace 200, or can move synchronously with the loader 110. When the collecting hopper 120 is fixed, the loader 110 can be separated from the collecting hopper 120 during its movement, and can be connected to the discharge port of the collecting hopper 120 when in the loading position, or the feed end of the loader 110 can always be connected to the discharge port of the collecting hopper 120. When the collecting hopper 120 moves synchronously with the loader 110, the feed end of the loader 110 can always be connected to the discharge port of the collecting hopper 120, and the collecting hopper 120 can be moved to a convenient position for loading to obtain raw materials.

[0042] Furthermore, the feeding device 100 further includes a hoisting mechanism, which is used to hoist the raw materials into the collecting hopper 120. Optionally, the hoisting mechanism includes a hanging rail and an electric hoist arranged on the hanging rail, and the hanging rail and the electric hoist are relatively conventional and will not be described in detail here.

[0043] In one embodiment, the feeding device 100 further comprises a moving frame 130 , and the feeding machine 110 is disposed on the moving frame 130 so as to be reciprocatingly movable. Preferably, the collecting hopper 120 is also disposed on the moving frame 130 .

[0044] In one embodiment, the stirring device 300 further includes a lifting mechanism 320 , which is connected to the stirring mechanism 310 to drive the stirring mechanism 310 to reciprocate along a first direction, so that the stirring mechanism 310 moves in and out of the melting furnace 200 during the reciprocating movement.

[0045] Furthermore, the stirring device 300 further includes a rotating mechanism 330, which is connected to the lifting mechanism 320 to drive the lifting mechanism 320 to rotate around an axis parallel to the first direction. The lifting mechanism 320 can pass through the stirring position during its rotation, and when the lifting mechanism 320 rotates to the stirring position, the stirring mechanism 310 corresponds to the feed port 210 of the melting furnace 200 in the first direction, so that the stirring mechanism 310 can enter and exit the melting furnace 200 during its movement along the first direction, and enter and exit the melting furnace 200 through the feed port 210. In this way, when loading or cleaning is required, the stirring mechanism 310 can be driven to move out of the melting furnace 200 by the lifting mechanism 320, and then the rotating mechanism 330 drives the lifting mechanism 320 to rotate, so as to drive the stirring mechanism 310 to leave the top of the melting furnace 200.

[0046] Optionally, the rotating mechanism 330 uses a motor to drive the lifting mechanism 320 to rotate, and the lifting mechanism 320 uses a motor and a transmission belt to drive the stirring mechanism 310 to rise and fall.

[0047] In one embodiment, the stirring device 300 further includes a base 340, a rotating rod 350 and a lifting rod 360. The rotating rod 350 is rotatably connected to the base 340 around the above-mentioned axis, and the rotating mechanism 330 is connected to the rotating rod 350 to drive the rotating rod 350 to rotate. The lifting rod 360 is arranged at an angle with the rotating rod 350, and one end of the lifting rod 360 is reciprocally connected to the rotating rod 350 along a first direction. The lifting mechanism 320 is arranged on the rotating rod 350 to rotate with the rotating rod 350, and the lifting mechanism 320 is connected to the lifting rod 360 to drive the lifting rod 360 to reciprocate along the first direction. The stirring mechanism 310 is connected to one end of the lifting rod 360 away from the rotating rod 350 so that it can leave the top of the melting furnace 200 during the rotation around the axis.

[0048] In one embodiment, the stirring mechanism 310 includes a stirring driving member 311 and a stirring blade 312. The stirring driving member 311 and the stirring blade 312 are both disposed on the lifting mechanism 320. The stirring blade 312 is rotatably disposed. The stirring driving member 311 is connected to the stirring blade 312 to drive the stirring blade 312 to rotate. The lifting mechanism 320 can drive the stirring driving member 311 and the stirring blade 312 to reciprocate along a first direction. The stirring blade 312 can enter and exit the melting furnace 200 during the movement along the first direction, so as to stir the raw materials after entering the melting furnace 200, so that the raw materials are heated evenly, the melting time is shortened, and the production efficiency is improved.

[0049] Furthermore, the stirring driving member 311 and the stirring blade 312 are both disposed on the lifting rod 360 , and the stirring driving member 311 is a motor, and the stirring driving member 311 is connected to the stirring blade 312 via a transmission belt.

[0050] In one embodiment, the stirring mechanism 310 also includes a connecting rod 313 and a heat insulation plate 314. The connecting rod 313 is rotatably disposed on the lifting rod 360. The stirring drive 311 is connected to the connecting rod 313 to drive the connecting rod 313 to rotate. The heat insulation plate 314 and the stirring blade 312 are both disposed on the connecting rod 313, and the heat insulation plate 314 is located between the stirring blade 312 and the lifting rod 360 to provide insulation during the stirring process to prevent high temperature from affecting the stirring drive 311.

[0051] In one embodiment, the melting furnace 200 uses electromagnetic induction heating to further shorten the time of melting the raw materials. It should be noted that in this embodiment, there are two melting furnaces 200 (two feeding devices 100 and two stirring devices 300), and a slag cleaning platform 500 is provided between the two melting furnaces 200. The operator can stand on the slag cleaning platform 500 to perform slag cleaning on the two melting furnaces 200.

[0052] In one embodiment, the ingot casting system also includes a dust removal hood 600, which is arranged on the melting furnace 200, and is provided with a loading port, a discharging port and a dust removal port 610. The loading port is used for the feeding device 100 to pass through, the discharging port is used for the guide member to pass through, and the dust removal port 610 is connected to the dust removal device for extracting the gas and smoke generated by the melting furnace 200 and treating them.

[0053] In one embodiment, the ingot casting machine 400 includes a conveyor belt and a plurality of molds, and the conveyor belt is used to transport the molds to the next process for demolding.

[0054] Furthermore, the ingot casting system also includes a guide member and a diverter, one end of the guide member is connected to the discharge port of the melting furnace 200, the diverter includes a collecting port and multiple diverter ports that are interconnected, the collecting port is connected to one end of the guide member away from the melting furnace 200, the multiple diverter ports are arranged at intervals corresponding to the ingot casting machine 400, and each diverter port corresponds to a mold to transport the smelting product into the mold for ingot casting.

[0055] It should be noted that, in order to prevent the smelting product from solidifying during the flow on the guide member, a heat preservation and heating device may be added to the guide member.

[0056] In one embodiment, the ingot casting system also includes a demolding device and a packaging device 700. The demolding device is arranged corresponding to the ingot casting machine 400 and is located at one end of the conveyor belt. It is used to receive the mold to demold it and convey the demolded finished product to the packaging device 700 located downstream. The packaging device 700 automatically packages and stores the finished product after it is cooled.

[0057] Furthermore, the packaging device 700 includes a palletizer and a baler, wherein the palletizer is arranged downstream of the demoulding device and is used to palletize uncooled finished products, and the baler can baling the cooled finished products. It is understandable that the palletizer has the property of being resistant to high temperatures.

[0058] In order to facilitate understanding of the technical solution of this application, Figure 1 The working process of the ingot casting system in the above embodiment is described as follows:

[0059] Initially, the stirring mechanism 310 is located outside the melting furnace 200 , and the lifting mechanism 320 is not in the stirring position.

[0060] First, the hoist hoists the raw materials into the collecting hopper 120, and then moves the collecting hopper 120 and the loader 110 until the loader 110 moves to the loading position, and starts the loader 110 to transport the raw materials into the melting furnace 200. After the loading is completed, the collecting hopper 120 and the loader 110 are removed. Next, the melting furnace 200 is started, and at the same time, the rotating mechanism 330 drives the lifting mechanism 320 to rotate to the stirring position, and then the lifting mechanism 320 drives the stirring mechanism 310 to descend, so that the stirring blade 312 enters the melting furnace 200, and then the stirring drive 311 is activated to drive the stirring blade 312 to stir the raw materials.

[0061] After smelting is completed, the discharge port of the melting furnace 200 is opened, and the smelted product flows into multiple molds through the guide piece and the diverter. During the process of the mold being transported by the conveyor belt, the smelted product is initially formed into a high-temperature finished product in the mold. Then the demoulding device demoulds the finished product and conveys the finished product to the palletizer. After the finished product is completely cooled, the packaging machine packages the finished product.

[0062] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
