[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0027] Embodiment 1: As attached Figure 1-8 As shown, a furnace dismantling machine includes a main plate 1, which is connected to a positioning system for fixing the whole and an impact system for dismantling the furnace. The main plate 1 is the main body of the whole equipment, and a lifting chain 2 is installed above the main plate 1 to suspend the equipment; an electric hoist 3 is arranged on the upper end of the lifting chain 2 to lift the equipment; four sets of bracket assemblies are connected to the main plate 1, which are evenly distributed around the main plate 1 and used when the equipment is placed.

[0028] like Figure 1 , 2 As shown in FIG. 8 , the bracket assembly includes a bracket rod 4 and a bracket seat 5. The bracket seat 5 is welded on the main plate 1 as a supporting point. The bracket rod 4 and the bracket seat 5 are hinged with a supporting shaft. The bracket rod 4 can rotate up and down around the shaft. When working, the bracket rod 4 rotates to the upper dead center. When placed, the bracket rod 4 rotates to the lower dead center. The tension spring is tightened when rotating to the upper and lower dead centers.

[0029] like Figure 3 As shown, the positioning system includes a support rail 6 fixedly connected to the main tray 1, a positioning pin 7 located in the support rail 6 and capable of telescopically sliding along the support rail 6, and a positioning motor 8 for driving the positioning pin 7 to move.

[0030] The positioning motor 8 is located at the center of the main disk 1. The positioning motor 8 is installed in the positioning motor cover and fixed to the main disk 1. The motor shaft passes downward through the main disk 1, and the active bevel gear 9 is installed at the end of the shaft. There are multiple groups of positioning pins 7, which are symmetrically arranged. In this embodiment, two groups are arranged, and other numbers of groups can also be arranged according to specific circumstances. Each positioning pin 7 is arranged radially along the main disk 1. The positioning pin 7 is assembled in the support rail 6 and can slide freely. A nut 11 is fixedly installed at one end of the positioning pin 7 close to the center of the main disk 1. The nut 11 is connected to a matching screw 12. The screw 12 is arranged parallel to the positioning pin 7. A driven bevel gear 10 is fixedly installed at one end of the screw 12 close to the center of the main disk 1. The active bevel gear 9 on the positioning motor 8 is engaged with the driven bevel gear 10. The telescopic function of the positioning pin 7 is achieved by the forward and reverse rotation of the positioning motor 8.

[0031] like Figure 4-5As shown, the impact system includes an impact disk 13 arranged parallel to the main disk 1 and an impact assembly 14 installed on the impact disk 13. The impact disk 13 is located below the main disk 1 and is connected to the main disk 1 through a tube shaft 15. The tube shaft 15 is located at the center of the main disk 1 and the impact disk 13. The tube shaft 15 is fixedly connected to the main disk 1. In this embodiment, the tube shaft 15 and the main disk 1 are welded as one. The impact disk 13 is installed at the middle end of the tube shaft 15 through a thrust bearing, and is tightened at the lower end of the tube shaft 15 with a spare cap. A rotating motor 16 is also fixed on the impact disk 13. The motor shaft of the rotating motor 16 passes through the impact disk 13. A driving gear 17 is fixed on the impact disk 13, and a driven gear 18 is fixed on the upper end of the tube shaft 15. The driving gear 17 is meshed with the driven gear 18. Through the forward and reverse rotation of the rotating motor 16, the function of driving the rotating disk as a whole to rotate forward and reverse is achieved.

[0032] like Figure 5-7 As shown, the impact assembly 14 is fixed on the impact disk 13, and the impact assembly 14 includes a main shell 19 fixed to the impact disk 13, an impact cylinder 20 in the main shell 19, and an impact piston 21 in the impact cylinder 20. The end of the impact piston 21 away from the center of the impact disk 13 is connected to the impact head 22. The end of the main shell 19 close to the center of the impact disk 13 is provided with a pneumatic chamber 27, and the pneumatic chamber 27 is connected to the external air source through the impact air inlet 28. The impact cylinder 20 is provided with an air inlet channel connected to the interior. In this embodiment, as shown in FIG. Figure 6 As shown, two air intake channels are provided, namely a first air intake channel 29 connected to the end of the impact piston 21 close to the impact head 22 and a second air intake channel 30 connected to the end of the impact piston 21 away from the impact head 22. A gas distribution valve 31 is provided at the second air intake channel 30. The gas distribution valve 31 controls the air to alternately enter the first air intake channel 29 and the second air intake channel 30, so that the impact piston reciprocates in the impact cylinder to realize the impact movement of the impact head.

[0033] When the external air source switch is turned on, air enters the air pressure chamber 27 through the impact air inlet 28, pushing the impact cylinder 20 forward as a whole. At the same time, air also enters the impact cylinder 20, pushing the impact piston 21 forward again. At this time, the cylinder exerts force forward, and the impact piston 21 drives the impact head 22 to perform impact movement, thereby completing the destruction of the sintered layer.

[0034] like Figure 6 As shown, a depth gauge 23 is also fixedly connected to the impact cylinder 20, and the depth gauge 23 is connected to a side close to the impact head 22 and is arranged parallel to the impact head 22. When the impact head 22 impacts the sintered layer, in order to prevent excessive impact and damage to the induction coil, the depth gauge 23 can be used to limit it.

[0035] When dismantling the furnace, the sintered layer is broken from bottom to top in sequence, air enters the air pressure chamber, and the impact cylinder 20 drives the impact head to move toward the sintered layer as a whole. At the same time, the air enters the first air inlet channel and the second air inlet channel in turn to drive the impact head to do impact movement to destroy the sintered layer. Since the depth gauge 23 is located above the impact head, when the impact head 22 penetrates the sintered layer to the set depth, the depth gauge 23 will contact the sintered layer at the same level above, thereby preventing the impact head 22 from impacting the sintered layer without limit and preventing damage to the induction coil. Therefore, in this application, the impact depth of the impact head can be preset in advance to control the damage to the sintered layer.

[0036] like Figure 5 and Figure 7 As shown, the main housing 19 is also connected with a pneumatic rod 24, and a housing 25 is sleeved on the outside of the pneumatic rod 24. The pneumatic rod 24 can slide along the housing 25 under the push of gas, one end of the housing 25 is fixed to the main housing 19, and the pneumatic rod 24 at the other end is fixed to the impact cylinder 20. The end of the housing 25 close to the impact cylinder 20 is provided with a pneumatic rod air inlet 26 connected to an external air source. When an impact point is completed, the air source of the pneumatic rod 24 is turned on, and the pneumatic rod 24 pulls the impact cylinder 20 back to its original position. This cycle is repeated.

[0037] Embodiment 2: A method for dismantling a furnace, wherein the equipment is lifted by an electric hoist 3, and the support rod 4 is folded upward to avoid hindering the rotation of the impact assembly. The equipment is suspended vertically into the crucible, and is dismantled layer by layer from the bottom. After the equipment is started, the positioning assembly is driven to extend outward by the positioning motor 8, and the positioning pin 7 is embedded in the sintered layer of the crucible. The two sets of positioning assemblies are symmetrically installed to keep the equipment in a centered state. After the positioning is completed, the impact assembly extends outward by air pressure and starts to impact. After the first impact point is completed, the impact assembly retracts, and is driven by the rotating motor 16 to make a small angle rotation, and then impacts the second point, and so on to complete the first circle of impact. After the first circle of impact is completed, the positioning assembly retracts, and the electric hoist 3 drives the equipment to lift slightly upward to start the second circle of dismantling. By analogy, after dismantling from the bottom to the top, the equipment is removed, the broken residues are cleaned up, and the dismantling is completed.
