Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0018] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0019] To improve the efficiency of maintenance and replacement of resistance wires in a titanium sponge reduction distillation furnace, in one embodiment, the present invention proposes a device for maintaining the resistance wires in a titanium sponge reduction distillation furnace, such as... Figure 1 As shown, it includes: an annular hanger 10, the outer diameter of which is larger than the furnace opening diameter of the sponge titanium reduction distillation furnace, and the inner diameter of which is smaller than the furnace opening diameter; multiple vertical telescopic supports 20, each vertical telescopic support 20 including multiple telescopic sections, the end of which is connected to the inner diameter edge of the annular hanger, and the multiple vertical telescopic supports are distributed in a ring; and multiple annular pedals 30, each annular pedal 30 being fixedly connected to the corresponding telescopic section.

[0020] Specifically, the sponge titanium reduction distillation furnace resistance wire maintenance device in this embodiment is designed as a retractable structure, which can be retracted when not in use to reduce space occupation and facilitate movement. When in use, it can be unfolded to extend into the furnace bottom and form maintenance platforms of multiple heights to facilitate the maintenance and replacement of the sponge titanium reduction distillation furnace resistance wire.

[0021] In one embodiment, such as Figure 2 As shown, the annular hanger 10 includes an inner ring frame 11 and an outer ring frame 12, and the inner ring frame 11 and the outer ring frame 12 are connected by steel bars 13 to ensure structural stability.

[0022] Optionally, the inner ring frame 11 and the outer ring frame 12 are made of steel pipes, and the steel bars 13 are made of steel bars or angle iron.

[0023] Optionally, steel bars 13 are connected by triangular welding between the inner and outer ring frames to ensure structural strength. The advantage of using a ring-shaped hanger is that it does not block natural light, facilitating construction under natural light.

[0024] In one embodiment, the annular hanger 10 further includes an annular slide rail 14 disposed near the inner diameter. The slide rail 14, and the corresponding device of the present invention, also includes a ladder 40. One end of the ladder 40 is provided with a sliding connector 41 and is suspended on the annular slide rail 14 through the sliding connector 41. The ladder body is close to the edge of the annular step 30 and extends into the furnace, so as to facilitate the workers to go down the ladder 40 into the furnace to perform maintenance and replacement operations on the various layers of the annular step 30.

[0025] Optional, such as Figure 3As shown, the slide rail 14 is also made of steel pipe and is fixedly connected to the annular hanger 10 via the elevated support 15; the corresponding sliding connector 41 is an inwardly bent hook, used to hook the slide rail 14 from below, allowing the escalator to move freely between the elevated supports 15, and facilitating the separation of the sliding connector from the slide rail 14 to cross the elevated supports 15. In this embodiment, the sliding connector 41 can utilize the weight of the escalator 40 itself to maintain the stability of reverse hoisting, and is easy to disassemble and move.

[0026] In one embodiment, the escalator 40 further includes lateral supports disposed on both sides of the escalator body and slidably abutting against the edges of the annular steps. Optionally, the lateral supports include grooves.

[0027] In one embodiment, such as Figure 4 As shown, each vertical telescopic bracket 20 includes: multiple sliding connecting plates 21, each sliding connecting plate having a sliding groove opening 22 at its center and pin holes 23 at the upper and lower ends of the sliding groove; and sliding pins, which pass through the pin holes of the current sliding connecting plate and the sliding groove opening 22 of the previous sliding connecting plate to achieve a sliding connection between the two.

[0028] Optionally, the sliding pin is a capped bolt, which can be fixed by engaging the nut with the sliding pin after the vertical telescopic bracket 20 is extended or retracted.

[0029] Optionally, the sliding connecting plate 21 can be a flat plate or a curved plate. The curved plate can better connect with the ring pedal 30.

[0030] Optionally, the sliding connecting plate 21 is welded to the annular pedal 30; or the sliding connecting plate 21 and the annular pedal 30 are detachably connected by bolts.

[0031] In one embodiment, the sponge titanium reduction distillation furnace resistance wire maintenance device of the present invention further includes a first lifting chain and a second lifting chain, wherein the first lifting chain spans across the inner diameter of the annular hanger 10, and the second lifting chain spans across the inner diameter of the annular pedal 30 furthest from the annular hanger 10. The first lifting chain is used when the device is lowered into and out of the furnace. After the device is removed, the device is reversed by lifting it with the second lifting chain, causing the device to retract under its own weight, and then the device is transferred to a storage location via the second lifting chain.

[0032] In one embodiment, the sponge titanium reduction distillation furnace resistance wire maintenance device of the present invention further includes a movable cover plate for sealing the central opening of the annular pedal.

[0033] like Figure 5As shown, when in use, the device is hoisted into the distillation furnace, with the annular hanger 10 supporting the top of the distillation furnace. Personnel can then access each platform 30 via the device's ladder 40 to inspect and repair the resistance wires of the distillation furnace. If the resistance wires of different layers need to be repaired simultaneously, after personnel enter each platform inside the device, they only need to cover the center opening of each layer with a movable cover plate to form a protective canopy, allowing simultaneous work on multiple platforms. Once the repair is complete, the entire device can be hoisted out and placed in its designated location.

[0034] In one embodiment, to accommodate the shape of the distillation furnace, the diameter of the annular footplate 30 decreases layer by layer, making the opening of the device tower-shaped.

[0035] To improve the efficiency of maintenance and replacement of resistance wires in a titanium sponge reduction distillation furnace, in another embodiment, the present invention proposes a maintenance device for resistance wires in a titanium sponge reduction distillation furnace, comprising: a rectangular hanger, the length of which is greater than the furnace opening diameter of the titanium sponge reduction distillation furnace; multiple vertical telescopic supports, each vertical telescopic support comprising multiple telescopic sections, the end of which is connected to the inner diameter edge of the rectangular hanger, the multiple vertical telescopic supports being rectangularly distributed; and multiple rectangular pedals, each rectangular pedal being fixedly connected to a corresponding telescopic section.

[0036] Specifically, the sponge titanium reduction distillation furnace resistance wire maintenance device in this embodiment is designed as a telescopic structure, which can be retracted when not in use to reduce space occupation and facilitate movement. When in use, it can be unfolded to extend into the furnace bottom and form maintenance platforms of multiple heights to facilitate the maintenance and replacement of the sponge titanium reduction distillation furnace resistance wire.

[0037] In one embodiment, the rectangular hanger includes left and right crossbeams connected by steel bars to ensure structural stability. Optionally, the left and right crossbeams are made of steel pipes, and the steel bars are made of reinforcing bars or angle iron.

[0038] Optionally, the steel bars are welded together in a triangular pattern between the left and right crossbeams to ensure structural strength. The advantage of using rectangular hangers is that they do not obstruct natural light, facilitating construction under natural light.

[0039] In one embodiment, the device of the present invention further includes a ladder, which is hung near the furnace opening of the reduction furnace for maintenance personnel to descend onto the corresponding rectangular footboard.

[0040] In one embodiment, each vertical telescopic bracket includes: multiple sliding connecting plates, each sliding connecting plate having a groove opening at its center and pin holes at the upper and lower ends of the groove; and sliding pins, which pass sequentially through the pin holes of the current sliding connecting plate and the groove opening of the previous sliding connecting plate to achieve a sliding connection between the two.

[0041] Optionally, the sliding pin is a capped bolt, which can be fixed by engaging the nut with the sliding pin after the vertical telescopic bracket 20 is extended or retracted.

[0042] Optionally, the sliding connecting plate can be a flat plate or a curved plate. The curved plate can better connect with the rectangular pedal.

[0043] Optionally, the sliding connecting plate is welded to the rectangular pedal; or the sliding connecting plate and the rectangular pedal are detachably connected by bolts.

[0044] In one embodiment, the sponge titanium reduction distillation furnace resistance wire maintenance device of the present invention further includes a first lifting chain and a second lifting chain, wherein the first lifting chain spans across the inner diameter of the rectangular hanger, and the second lifting chain spans across the inner diameter of the rectangular pedal furthest from the rectangular hanger. The first lifting chain is used when the device is lowered and removed from the furnace. After the device is removed, the device is reversed by lifting it with the second lifting chain, causing the device to retract under its own weight, and then the device is transferred to a storage location via the second lifting chain.

[0045] In one embodiment, the sponge titanium reduction distillation furnace resistance wire maintenance device of the present invention further includes a movable cover plate for sealing the center opening of the rectangular pedal.

[0046] When in use, the device is hoisted into the distillation furnace, with the rectangular hanger placed at the top of the furnace. Personnel can then access each platform via the device's ladder to inspect and repair the resistance wires of the distillation furnace. If the resistance wires of different layers need to be repaired simultaneously, after personnel enter each platform, they only need to cover the center opening of each layer with a movable cover plate to form a protective canopy, allowing for simultaneous work on multiple platforms. Once the repair is complete, the device can be hoisted out and placed in its designated location.

[0047] In one embodiment, to accommodate the shape of the distillation furnace, the length of the rectangular pedal decreases layer by layer, making the opening of the device tower-shaped.
