Description

Alloy mechanical crushing packaging system

Technical Field

The utility model relates to the technical field of alloy production, in particular to an alloy mechanized crushing and packaging system.

Background

The alloy is widely applied to the industrial fields of materials, metallurgy, construction and the like, but when the alloy is used, the alloy material is firstly required to be crushed so that the granularity of the alloy material reaches the use requirement. The crushed alloy material also needs to be screened according to the industrial requirement, and the alloy material with qualified granularity obtained through screening is packaged and transported to enter the next working procedure. In crushing and screening operations, there are often problems of low efficiency of manual crushing, screening and packaging operations and poor working environment. Taking a silicon-manganese alloy product as an example, the silicon-manganese alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements, and is an iron alloy with wider application and larger yield. The Si-Mn alloy product is a common composite desulfurizing agent, deoxidizing agent and alloy additive for steel smelting, and has the characteristics of hard strength and broken structure. Typically, when used in the steelmaking industry, the silicon-manganese alloy product is processed to the grain size required by the steelworks (typically 10-50mm or 30-100 mm), and the grain size of the cast silicon-manganese alloy product is mostly 50-200mm. Therefore, in order to meet the subsequent use requirements, the silicomanganese alloy product needs to be crushed, a small amount of slag and powder are finished, the part with too small granularity is removed, and finally the silicomanganese alloy product with qualified granularity is packaged in a bag.

At present, most production enterprises have higher production capacity, however, the crushing, finishing and packaging of the cast silicon-manganese alloy products basically adopt manual operation, the manual efficiency is low, the time cost is high, the labor intensity is high, in addition, in the process of carrying out the manual operation, the produced powder, dust and the like are easy to influence the surrounding environment, the labor operation environment is poor, and the labor cost of the part also can cause the increase of the production cost. If the existing crushing equipment is used for crushing the silicon-manganese alloy, the crushing effect is not ideal, the crushed silicon-manganese alloy has different particle sizes, fragments, slag, powder and the like caused by crushing still need to be manually sorted and finished, and unqualified products need to be manually removed before packaging, and then bagging and packaging are carried out. Therefore, the mechanical crushing packaging production line for alloy products is of great importance to the production enterprises to improve the production efficiency and reduce the production cost.
