[0031] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] Please see Figures 1 to 12 The present invention preferably provides the following technical solution: a large induction furnace, comprising: a frame structure, and a drive assembly disposed on the upper part of the frame structure and rotatable, wherein a furnace body structure is disposed on the opposite side of the drive assembly, and the frame structure and the drive assembly are respectively used to drive the two ends of the furnace body structure to rotate slightly up and down and rotate slightly forward and backward; it also includes an induction body assembly disposed at an incline on the lower part of the furnace body structure and detachable, and the induction body assembly is symmetrically distributed on both sides of the furnace body structure to form a double melt channel jet.

[0034] like Figure 1 , 3 As shown in Figures 4 and 7, the furnace body structure is positioned opposite the drive assembly, which in turn is mounted on the frame structure. The frame structure and drive assembly are used to drive the furnace body structure to rotate alternately up and down and flip back and forth. This design, on the one hand, accelerates the smelting process of the zinc blocks, and the slight flipping of the furnace body structure can impact the inner wall of the furnace body structure to clean the slag. On the other hand, the forward and backward flipping of the furnace body structure further facilitates the replacement of the induction element assembly tilted at the bottom of the furnace body structure. The tilting of the induction element assembly ensures that the normally operating induction element assembly still has the heat of zinc melting and continuous flow when disassembling the induction element assembly. It also prevents blasting during feeding and impact on the induction element.

[0035] Furthermore, the furnace structure includes a support column 55 and a furnace body 16 fixed to the opposite side of the support column 55, and also includes a refractory lining disposed on the inner wall of the furnace body 16. The refractory lining is composed of an outer layer of calcium silicate board 41, a middle layer of clay bricks 40 and an inner layer of low-cement castable 39.

[0036] The refractory lining installed on the inner wall of the furnace body 16 consists of an outer layer of calcium silicate board 41, a middle layer of clay bricks 40, and an inner layer of low-cement castable 39. Figure 7 As shown, calcium silicate board 41, as a new type of green and environmentally friendly building material, not only has the functions of traditional gypsum board, but also has the advantages of superior fire resistance, moisture resistance, and ultra-long service life.

[0037] Clay brick 40 is made from clay powder, including shale and coal gangue, as the main raw materials. It is produced by mud processing, molding, drying and firing. Qualified clay brick 40 is a phosphate-impregnated product that is vacuum phosphate impregnated and fired at low temperature twice after drying. It is widely used for blast furnace lining.

[0038] Low-cement castable 39 refers to a new type of castable with very low binder content. The key feature is the use of ultrafine particles of no more than 1μm, which significantly improves its thermal shock resistance, slag resistance, and erosion resistance, surpassing similar refractory bricks.

[0039] Example 2

[0040] In another embodiment of the present invention, the induction assembly includes a housing 18, which is detachably installed in a slot at the lower part of the furnace body 16, and suction assemblies disposed inside the housing 18 and symmetrically distributed therein. Each suction assembly contains a first induction structure. Each suction assembly includes a mounting sleeve 42 fixed to the inner wall of the housing 18, which is composed of a straight section and a circular section, and the straight section and the circular section are connected. It also includes an outlet 44 and an inlet 43 opened in the circular section of the mounting sleeve 42, which are located on both sides of the straight section of the mounting sleeve 42 and are used for drawing in and spraying out molten zinc, respectively. It further includes a first furnace lining sleeve eccentrically disposed inside the mounting sleeve 42. 48. When the first furnace lining sleeve 48 rotates inside the mounting sleeve 42, the first furnace lining sleeve 48 can be tightly attached to the inner wall of the mounting sleeve 42, and the first sensing element structure is placed inside the first furnace lining sleeve 48; and a limiting block 47 is slidably installed inside the straight section of the mounting sleeve 42, a connecting plate 45 is connected between the limiting block 47 and the first furnace lining sleeve 48, and one end of the connecting plate 45 is rotatably connected to the limiting block 47, and the other end is fixedly connected to the first furnace lining sleeve 48; it also includes two micro motors 54 disposed on the outer wall of the housing 18, and the output end of each micro motor 54 passes through the housing 18 and the mounting sleeve 42 in sequence and is fixedly connected to the protrusion where the first furnace lining sleeve 48 is located, such as Figure 11 As shown.

[0041] Because the shell 18 and the slot at the bottom of the furnace body 16 are detachably installed, such as Figure 2 , 7 As shown, this facilitates the disassembly of the housing 18;

[0042] The housing 18 contains two sets of suction components arranged symmetrically. Each set of suction components contains a first sensor structure, such as... Figure 8 , 9 As shown in Figure 10, the first induction structure is disposed inside the first furnace lining sleeve 48, and the first furnace lining sleeve 48 is eccentrically disposed inside the mounting sleeve 42, as shown in Figure 10. Figure 10 As shown, the mounting sleeve 42 is composed of a straight section and a circular section, which are connected. An outlet 44 and an inlet 43 are provided on the circular section of the mounting sleeve 42. The outlet 44 and inlet 43 are located on both sides of the straight section of the mounting sleeve 42, and are used for drawing in and spraying out molten zinc, respectively. A connecting plate 45 connects the first furnace lining sleeve 48 and the limiting block 47 inside the straight section of the mounting sleeve 42. Therefore, when the first furnace lining sleeve 48 rotates eccentrically inside the mounting sleeve 42, a connecting plate 45 is provided between them. Figure 10 Taking the right-side suction assembly as an example, when the first furnace liner 48 deflects clockwise and moves clockwise against the inner wall of the right side of the mounting sleeve 42, the space on the right side of the connecting plate 45 gradually increases, thereby drawing the molten zinc inside the furnace body 16 to the right side of the connecting plate 45. At the same time, the left side of the connecting plate 45 decreases, thereby spraying out the molten zinc drawn into the mounting sleeve 42 to complete the unidirectional melting and spraying process of the molten zinc. Since the two sets of suction assemblies are not symmetrically distributed, a double melting groove is formed under the action of electromagnetic compression force, thereby drawing the molten zinc from the outside and spraying it out to the center to achieve rapid unidirectional circulation of the molten zinc, reducing the temperature difference between the shell 18 and the inside of the furnace body 16, thereby improving the service life of the first induction structure.

[0043] Furthermore, the first induction structure includes a plurality of coils 49 disposed inside the first furnace liner 48, and an iron core 50 disposed inside the plurality of coils 49; it also includes a second furnace liner 51 disposed between the two sets of suction components, and the second furnace liner 51 is provided with a second induction structure inside, further accelerating the smelting and casting efficiency of the zinc melt; the second induction structure is the same as the first induction structure, and only the first induction structure will be explained here.

[0044] By using several wound coils 49 arranged inside the first furnace liner 48 and an iron core 50 arranged inside the coils 49, in conjunction with the first furnace liner 48, under the action of electromagnetic force, this part of the structure can form a heating induction body, thereby melting and forging the molten zinc.

[0045] Example 3

[0046] In another embodiment of the present invention, the frame structure includes a support frame 1 and two sets of connecting components disposed on opposite upper surfaces of the support frame 1. Each set of connecting components includes two plug-in blocks 8 fixed to the end of the support frame 1 and a movable column 9 vertically disposed between the two plug-in blocks 8. The plug-in blocks 8 can slide within a long groove 10 opened on the side wall of the movable column 9. The drive component is disposed on the opposite surface of the two movable columns 9. The frame structure also includes mounting blocks disposed at both ends of the lower part of the support frame 1. The opposite surface of the mounting blocks is provided with a rotatable screw 4 and two threaded sleeves 2 threadedly connected to the screw 4. A transmission component 5 is fixed on the upper part of the two threaded sleeves 2. The transmission component 5 is symmetrically provided with transmission grooves 6. The transmission column 7 fixed at the bottom of each movable column 9 can slide within the corresponding transmission groove 6. When the transmission component 5 moves left and right, it is used to drive the two ends of the drive structure to deflect slightly up and down in an alternating manner. The frame structure also includes a drive motor 3 disposed on the side wall of one of the mounting blocks. The output end of the drive motor 3 passes through the mounting block and is fixedly connected to the screw 4.

[0047] like Figure 1As shown, since the plug-in block 8 can slide within the long slot 10 opened on the side wall of the movable column 9, and the mounting blocks at the lower part of the support frame 1 are rotatably connected by a screw 4, with two threaded sleeves 2 threaded onto the screw 4, and also includes a transmission component 5 set on the two threaded sleeves 2, and the transmission column 7 fixed at the bottom of the two movable columns 9 can move within the transmission slots 6 symmetrically opened on the transmission component 5, therefore, by rotating the screw 4, the transmission component 5 can move left and right, and the transmission slots 6 opened on the transmission component 5 are symmetrically distributed, such as... Figure 3 As shown, this causes the two movable columns 9 to move up and down alternately, and further causes the two ends of the drive component to deflect slightly when they move up and down alternately.

[0048] Furthermore, the drive assembly is provided in two sets, which are respectively placed on the top of the two movable columns 9. The two sets of drive assemblies include two mounting parts 11, with a first mounting plate 59 and a second mounting plate 60 fixed to opposite ends of the two mounting parts 11 respectively. The first mounting plate 59 is rotatably connected to one of the movable columns 9 by a pin. It also includes a second limiting groove opened laterally on the transmission groove 6, and a limiting post fixed to the top of the other movable column 9 can move inside the second limiting groove. It also includes a mounting plate 23 fixed on each mounting part 11, and a transmission plate 12 rotatably connected to the side wall of the mounting plate 23. The support column 55 and the support rod 58 are respectively fixed in the middle and lower part of the transmission plate 12. When the transmission plate 12 rotates, it is used to drive the furnace body 16 to rotate. It also includes a third motor 14 fixed on the mounting plate 23, a third transmission gear 13 fixed to the output end of the third motor 14, and a third external gear ring 15 fixed to the outer wall of the transmission plate 12, and the third external gear ring 15 meshes with the third transmission gear 13.

[0049] Since one of the movable columns 9 is rotatably connected to the first mounting plate 59 where the mounting component 11 is located via a pin, and the limiting column fixed by the other movable column 9 can move inside the second limiting groove where the second mounting plate 60 fixed by the other mounting component 11 is located, when the two movable columns 9 move up and down alternately, the two drive components deflect alternately accordingly.

[0050] like Figure 12 As shown, the two mounting parts 11 are fixed with mounting disks 23 on their opposite sides, and a transmission disk 12 is rotatably connected to the opposite sides of the two mounting disks 23. The support column 55 and the support rod 58 are fixed in the middle and lower part of the transmission disk 12, respectively. A third motor 14 is provided on the mounting disk 23, and a third transmission gear 13 is fixed at the output end of the third motor 14. A third external gear ring 15 is fixed on the outer wall of the transmission disk 12, and the third external gear ring 15 meshes with the third transmission gear 13. Therefore, by driving the third motor 14, the transmission disk 12 can be rotated to achieve the front and rear deflection of the furnace body structure.

[0051] Example 4

[0052] In other embodiments of the present invention, a preheating and stirring assembly is also included inside the furnace body 16 for preheating and pre-stirring the zinc blocks. The preheating and stirring assembly includes a support rod 58 fixed to the side wall of the transmission disk 12, one end of which passes through the furnace body 16 and is fixed to a connecting disk 31. A first limiting groove 32 is provided on the connecting disk 31. The assembly also includes a movable ring 30 rotatably connected to the outer wall of the connecting disk 31, one end of which extends through the furnace body 16 to the outside and is provided with a first meshing drive structure between it and the furnace body 16 to provide power for the rotation of the movable ring 30. Furthermore, a transmission assembly is provided between the movable ring 30 and the connecting disk 31. The furnace body 16 is equipped with several components arranged in a ring. Each transmission component includes a mounting shaft 33 disposed on the side wall of the movable ring 30, and a transmission rod 34 rotatably connected to the mounting shaft 33. It also includes a limiting post disposed on the end of the transmission rod 34 away from the mounting shaft 33, and one end of the limiting post can move inside the first limiting groove 32. The other end of the limiting post is also fixed with a heating tube 35. When the movable ring 30 rotates, the heating tube 35 is used to preheat the zinc blocks inside the furnace body 16. The furnace body 16 also includes a mounting rod 36 fixed on the end of the transmission rod 34 near the mounting shaft 33, and a stirring bar 37 fixed on the end of the mounting rod 36 away from the mounting shaft 33 for stirring the zinc blocks inside the furnace body 16.

[0053] Because the support rod 58 fixed to the side wall of the transmission disc 12 passes through the furnace body 16 and is fixed to the connecting disc 31, and the outer wall of the connecting disc 31 is rotatably connected to a movable ring 30, and one end of the movable ring 30 passes through the furnace body 16 and is provided with a first meshing drive assembly, it can provide power for the rotation of the movable ring 30, such as Figure 12 As shown, a ring-shaped transmission assembly is provided between the connecting disc 31 and the movable ring 30, such as... Figure 4 , 5 As shown, the transmission assembly includes a transmission rod 34, one end of which is rotatably connected to the movable ring 30 via a mounting shaft 33. The other end of the rod is provided with a limiting post that can be limited to move within the first limiting groove 32 opened on the connecting plate 31. At this time, the heating tube 35 on the limiting post can preheat the stacked zinc blocks inside the furnace body 16, so that they are melted and become molten zinc. The transmission rod 34 is also fixed with a mounting rod 36 near the mounting shaft 33, which can stir the stacked zinc blocks to accelerate the melting of the stacked zinc blocks. The movable ring 30 can rotate relative to the connecting plate 31, so that several transmission components can be deflected to realize the stirring and circulating heating process of the stacked zinc blocks.

[0054] This design achieves preheating and pre-stirring of the zinc ingots through the preheating and stirring components. Combined with the structural characteristics of the inductor components, it realizes a multi-stage smelting and casting process for the zinc ingots, thereby greatly improving the smelting quality of the zinc ingots.

[0055] Furthermore, the first meshing drive structure includes a first external toothed ring 57 fixed to the outer end of the movable ring 30; and a first motor 56 disposed on the outer wall of the furnace body 16, and also includes a first transmission tooth 25 fixed to the output end of the first motor 56, and the first transmission tooth 25 meshes with the first external toothed ring 57.

[0056] Since the first transmission tooth 25 meshes with the first external toothed ring 57, and the first transmission tooth 25 is fixed to the output end of the first motor 56, and the first external toothed ring 57 is fixed to the outer end of the movable ring 30, as... Figure 12 As shown, the operation of the transmission components can be achieved.

[0057] Furthermore, the connecting disc 31 is shaped like a teardrop with its tip pointing downwards.

[0058] like Figure 4 As shown, due to the shape characteristics of the connecting plate 31 and the fixed connection between the transmission rod 34 and the mounting rod 36, when the limiting post at one end of the transmission rod 34 runs to the tip of the first limiting groove 32, it can drive the mounting rod 36 to deflect outward.
