Abstract
Description
Technical Field
[0001] The present invention relates to the field of titanium sponge production, and particularly to a device and method for removing titanium lumps in the titanium sponge industry. Background Art
[0002] Currently, the work of removing titanium lumps on the No. 1 production line of Gansu Guotai is carried out manually. During the process of removing the lumps, first, the workers use a pneumatic pick to strip the climbing titanium manually, and then clean the adhered part between the reactor and the titanium lump, so that the steel wire rope can be inserted into the gap between the titanium lump and the reactor. After buckling the titanium lump, a crane is used to lift it, and the reactor and the titanium lump are separated by the self-weight of the reactor to complete the process of removing the lump. When removing the titanium lump and hoisting the reactor, a crane is required for cooperation. Considering the current location of the titanium lump removal area, the crane is too busy, making the entire process take an average of 7 - 10 hours, and it takes 2 - 3 days for difficult-to-remove lumps.
[0003] The defects of this solution are as follows: First: Time-consuming and laborious; Second: It must rely on the steel wire rope being able to be inserted into the gap between the titanium lump and the reactor; without a gap, it cannot be pulled out; Third: The shape of the titanium lump will not be a standard shape and will not be formed according to people's preferences. In many cases, there are no suitable pulling process conditions; Fourth: It requires the cooperation of a crane; the crane is too busy; Fifth: A large amount of steel wire is used, resulting in losses.
