Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to material compaction technical field, and specifically relates to a material compaction device for crucible aluminothermic reaction. BACKGROUND
[0002] Aluminothermic method is commonly used in industry to produce intermediate alloy such as ferrotitanium, ferromolybdenum, ferro niobium, ferroboron, ferrovanadium, ferrotungsten, metallic chromium, metallic manganese, nickel-based, titanium-based and aluminum-based intermediate alloy. In the production of intermediate alloy, aluminum powder and other ingredients are mixed uniformly and compacted after being proportioned according to a certain ratio, so that the material is loaded into the crucible at a suitable and uniform density, and the aluminothermic reaction is carried out smoothly at a suitable reaction speed, thereby improving the uniformity of chemical composition and the metal yield of the intermediate alloy.
[0003] In the prior art, the compaction of the material is carried out by manual ramming or mechanical vibration. Manual ramming needs to be carried out for multiple times to complete the compaction, which is time-consuming, labor-intensive and low in efficiency, and makes it difficult to expand the production scale of the intermediate alloy. Moreover, the manual ramming process is accompanied by serious dust pollution.
[0004] The mechanical vibration has instability, which causes the material density to be uneven, and requires high quality and structure of the crucible and the crucible frame. The mechanical vibration requires that the specific gravity difference of various raw materials in the material should not be too large, and is suitable for a small number of products. The mechanical vibration is accompanied by serious dust pollution and noise pollution due to large noise and dust. The mechanical vibration process is time-consuming, and the time from loading the material to the end of the vibration treatment is usually more than 8 minutes, which is low in efficiency.

[0007] A lead screw is provided on the platform of the base, and the bottom of the hydraulic lifting platform is connected to the lead screw by a nut. The lead screw is driven by a motor to move the hydraulic lifting platform back and forth along the linear guide rail.
[0008] One of the pair of support shafts is connected to the second motor via a pulley pair, and the second motor drives the female mold to rotate around the pair of support shafts.
[0009] The inner diameter of the sleeve is smaller than the inner diameter of the crucible, and the inner diameter of the sleeve at the end away from the base is slightly larger than the inner diameter of the other end, so that the inner wall of the sleeve forms a demolding slope.
