Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgical industry, and more particularly to an automatic furnace tamping device with a half-tooth gear as a driving mechanism. Background Art
[0002] During the aluminothermic reduction reaction in the metallurgical industry's one-step vanadium-aluminum alloy preparation process, aluminum and vanadium must be mixed beforehand and then loaded into a reactor for the aluminothermic reduction reaction. The intensity of the aluminothermic reduction reaction can affect the level of gaseous impurities in the vanadium-aluminum alloy. Excessive reaction intensity can also cause material to splash out of the reactor, reducing the vanadium content of the finished alloy.
[0003] Because the quality of vanadium-aluminum alloys significantly impacts the purity of related titanium alloy products using them, a tamping process is added after the vanadium and aluminum are mixed and charged into the furnace. This process compacts the mixed materials, ensuring a relatively smooth and slow combustion during the thermite reduction reaction. Currently, tamping is performed manually, which is inconvenient and inefficient.
[0004] Therefore, it is an urgent problem for those skilled in the art to develop an automatic tamping furnace device that is easy to operate, has high efficiency, and can mix materials with a solid and fastened half-toothed gear as a driving mechanism. Utility Model Content
[0005] In view of this, the utility model provides an automatic furnace tamping device which is easy to operate, high in efficiency and can mix materials and uses a solid and fastened half-tooth gear as a driving mechanism.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] An automatic furnace tamping device using a half-toothed gear as a driving mechanism comprises:
[0008] Support platform,
[0009] A reaction furnace, the reaction furnace being arranged at the bottom of the supporting platform;
[0010] A lifting drive mechanism, the lifting drive mechanism includes: a sliding rod hammer handle, a sliding sleeve, a half-toothed gear and a driving motor; the support platform is provided with a through hole at a position above the reactor; the sliding sleeve is passed through the through hole and is connected to the support platform; the sliding rod hammer handle is placed in the sliding sleeve and is slidingly connected to the sliding sleeve; the driving motor is arranged on the top of the supporting platform, and the output end of the driving motor is connected to the half-toothed gear; the surface of the sliding rod hammer handle is provided with teeth that mesh with the teeth of the half-toothed gear.
[0011] The beneficial effect of adopting the above technical solution is that the rotation of the half-toothed gear in the utility model drives the sliding hammer handle to move upward, and then falls to compact the material in the reactor, which can realize the automatic compaction process, reduce manual operation, and improve work efficiency.
[0012] Preferably, the side of the sliding hammer handle that contacts the half-toothed gear is provided with an insertion slot, into which a rack is inserted, and the rack meshes with the half-toothed gear. The rack is provided only on a section of the surface of the sliding hammer handle. This arrangement ensures that after the half-toothed gear rotates half a turn, the sliding hammer handle and the half-toothed gear can be disengaged, allowing the sliding hammer handle to automatically fall to compact the material.
[0013] Preferably, a hoist is provided on the top of the support platform, and a steel wire rope of the hoist is connected to the top of the slide bar hammer handle. When the drive motor stops, the hoist can lift the slide bar hammer handle to the top, making it convenient for the reactor to exit and enter the combustion chamber for the next process.
[0014] Preferably, a lifting bracket is provided on the top of the support platform, the lifting bracket is placed between the hoist and the slide bar hammer handle, and a steel wire rope is placed on the top of the lifting bracket. The lifting bracket supports the steel wire rope, making it convenient to lift the slide bar hammer handle.
[0015] Preferably, the top height of the lifting bracket is higher than the top height of the sliding bar hammer handle.
[0016] Preferably, the shape of the hammer handle at the bottom of the sliding rod hammer handle is the same as the shape of the inner cavity of the reactor, so that the sliding rod hammer handle can compact the material in the reactor more firmly.
[0017] Preferably, the slide bar hammer handle is made of stainless steel.
[0018] It can be seen from the above technical solution that, compared with the prior art, the present invention discloses an automatic furnace tamping device using a half-toothed gear as a driving mechanism, which has the following beneficial effects:
[0019] (1) The automatic furnace tamping device of the utility model uses a half-toothed gear as a driving mechanism to drive the sliding rod hammer handle to rise, and then relies on the gravity of the sliding rod hammer handle to fall, thereby tamping the material in the furnace;
[0020] (2) The automatic furnace tamping device has a simple structure and is easy to operate. It makes the loose materials in the furnace more solid and firm through the tamping action of the sliding rod hammer handle, and is suitable for promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Support platform 1,
[0036] A reaction furnace 2, the reaction furnace 2 is arranged at the bottom of the support platform 1;
[0037] The lifting drive mechanism 3 includes: a slide bar hammer handle 31, a sleeve 32, a half-toothed gear 33 and a drive motor 34; the support platform 1 is provided with a through hole 11 at a position above the reactor 2; the sleeve 32 is passed through the through hole 11 and is connected to the support platform 1; the slide bar hammer handle 31 is placed in the sleeve 32 and is slidably connected to the sleeve 32; the drive motor 34 is arranged on the top of the support platform 1, and the output end of the drive motor 34 is connected to the half-toothed gear 44; the surface of the slide bar hammer handle 31 is provided with teeth that mesh with the teeth of the half-toothed gear 33.
[0038] To further optimize the above technical solution, a slot 35 is formed on the side of the slide hammer handle 31 that contacts the half-toothed gear 33. A rack 36 is inserted into the slot 35, and the rack 36 meshes with the half-toothed gear 33. Both the rack 36 and the half-toothed gear 33 are heat-treated to increase their hardness and lifespan.
[0039] In order to further optimize the above technical solution, a hoist 4 is provided on the top of the support platform 1, and the wire rope of the hoist 4 is connected to the top of the slide bar hammer handle 31. A lifting ring is provided on the top of the slide bar hammer handle 31, and the wire rope is connected to the lifting ring.
[0040] In order to further optimize the above technical solution, a lifting bracket 5 is provided on the top of the support platform 1 , the lifting bracket 5 is placed between the hoist 4 and the slide bar hammer handle 31 , and a steel wire rope is placed on the top of the lifting bracket 5 .
[0041] In order to further optimize the above technical solution, the top height of the lifting bracket 5 is higher than the top height of the slide bar hammer handle 31 .
[0042] In order to further optimize the above technical solution, the shape of the hammer handle at the bottom of the sliding rod hammer handle 31 is the same as the shape of the inner cavity of the reactor 2 .
[0043] In order to further optimize the above technical solution, the slide bar hammer handle 31 is made of stainless steel, 4, namely 304 stainless steel, which can prevent the tamping device from contaminating the materials in the reactor 2.

[0044] The use process of the automatic tamping furnace device:
[0045] Mixed vanadium, aluminum, and other materials are placed into reactor 2. Reactor 2 is then pushed below support platform 2, directly opposite slide hammer handle 31.

When the first tooth of half-toothed gear 33 engages with rack 36 embedded in slide hammer handle 31, slide hammer handle 31 and rack 36 begin to rise. When the last tooth of half-toothed gear 33 disengages from rack 36 embedded in slide hammer handle 31, slide hammer handle 31 falls under its own weight, impacting the materials in reactor 2. This process is repeated until the materials in reactor 2 are firm. The repeated tamping is stopped, drive motor 34 is shut down, and hoist 4 is restarted to raise slide hammer handle 31 to the top. Finally, reactor 2 is withdrawn and placed into the combustion chamber for the next step.
