Description

Titanium sponge lifting appliance

Technical Field

The utility model relates to an anchor clamps that is used for cylindrical titanium top of titanium sponge workshop handling belongs to titanium sponge processing technology field.

Background

Titanium is an important rare metal, has the characteristics of light weight, corrosion resistance and wear resistance, and is widely applied to the industrial departments of aviation, navigation, chemical industry, petroleum and the like.

When the titanium sponge is produced by a magnesiothermic reduction vacuum distillation method, refined magnesium and refined titanium tetrachloride are placed in a reactor and react at 850 ℃ to generate titanium sponge, and the obtained titanium sponge is subjected to vacuum distillation at the temperature of 1000 ℃ to obtain pure titanium sponge. In the titanium sponge production process, the titanium lump needs to be taken out from the tank body in the titanium sponge processing workshop to carry out operations such as slicing, crushing and grading packaging on the titanium lump.

The invention patent (publication number 104099472A) applied by Panzhihua iron and steel research institute Limited company of Panzhihua steel of Panzhihua group discloses a titanium lump ejection system and two titanium lump ejection methods, wherein the titanium lump ejection system comprises a travelling crane, a tank body and a hydraulic mechanism, the travelling crane is arranged above the tank body and is connected with the tank body through a steel cable, the hydraulic mechanism is arranged below the tank body, an upward convex top pillar is arranged on the hydraulic mechanism, the top pillar is vertically arranged in the axial direction, a movable bottom plate is arranged at the bottom of the tank body, a bottom hole is formed in the bottom of the tank body below the movable bottom plate, and the top pillar is arranged in the bottom hole. The titanium lump ejection method comprises the steps of hoisting a tank body filled with the titanium lump and conveying the tank body to the upper part of an ejection column; slowly putting down the tank body, and using the gravity of the tank body to enable the ejection column to eject the titanium lump, or clamping the tank body by a clamping mechanism, and driving the ejection column by a hydraulic mechanism to eject the titanium lump. By using the titanium lump ejection system and the titanium lump ejection method, the opening of the tank body can be kept upward, the titanium lump can be ejected upward, and the problem that the tank body is excessively abraded when the titanium lump is ejected horizontally in the traditional method is solved.

However, in the titanium sponge processing workshop of the titanium smeltery, after the titanium sponge lumps are ejected out of the reduction tank, the titanium sponge lumps need to be lifted to a titanium lump processing platform and a titanium sponge slicing machine for subsequent processing. Because the titanium top temperature is still higher at this moment, adopt traditional wire rope to bind the reuse overhead traveling crane handling mode, easily take place high temperature and scald the incident, and this kind of mode needs several operation workman auxiliary operation, and operating time is longer, and efficiency is also lower.

Therefore, how to hoist the titanium lump after being ejected becomes a technical problem which needs to be solved urgently.

Disclosure of Invention

The utility model provides a titanium sponge lifting appliance that sticks together, this lifting appliance can lift by crane cylindrical titanium sponge top, during the use, only need a workman supplementary can to overcome the many people auxiliary operation that prior art exists, easily take place high temperature and scald the risk, production efficiency is lower wait not enough.
