Description

A kind of unpacking bucket device for ferrosilicon clump and using method thereof

technical field

The invention belongs to the technical field of metallurgical equipment, and in particular relates to an unpacking hopper device for ferrosilicon clumps and a use method thereof.

Background technique

Ferrosilicon lumps are lumps of ferrosilicon wrapped in woven bags. Bulk ferrosilicon is a commonly used alloy charge for steelmaking in the metallurgical industry. From the production site of bulk ferrosilicon to the ferrosilicon warehouse, it is transported in the form of ferrosilicon clumps. When ferrosilicon clumps are used for steelmaking, Then you need to open the ferrosilicon block to load the bucket. Due to the dangerous properties of ferrosilicon, it emits hydrogen when it comes in contact with water, alkalis or acids, can form explosive mixtures with air, and can react violently with oxidants. The highly toxic gases of arsenic and phosphine are emitted. Therefore, the storage, transportation and unpacking of ferrosilicon have strict requirements. There are also various ways to open the bale. The current working method of our company is to manually cut the bale. This operation method is very primitive and dangerous, and is prone to safety accidents.

The existing working method is to manually open the woven bag to wrap, and then load it into a hopper (that is, into a hopper). There are generally two methods for manual opening. One is to place the ferrosilicon package on the ground for unpacking or manual cutting and then loading into the bucket; The operator extends the cutting rod 9 into the bottom of the bale, and after breaking the bale from the bottom, the massive ferrosilicon falls into the hopper. At present, people use a cutting stick (metal) to put it into the fire to burn red, and then extend it into the bottom of the ferrosilicon block to iron the bag, and the woven bag is broken open by the high temperature. The former method has long time and low work efficiency; although the latter method is fast and efficient, it brings at least two problems:

1. The operation method is dangerous. The manual method is broken from the bottom of the bag, and the ferrosilicon block spilled from the bag may splash out and hurt the operator.

2. Pollute the environment. Because the bag block is suspended in the air, a large amount of dust is generated after the bag is broken, which causes environmental pollution and seriously affects the health of operators.
