Description
Technical field
The utility model relates to a kind of dust arrester, relates in particular to a kind of separator that carries out the particle surface dust of dedusting separation for slag molding sand finished product.
Background technology
The at present domestic spraying coating process that extensively adopts in industries such as structure steel fabrication, Ship's Repair eliminates rust, and materials such as the shot that uses, quartz sand, copper ore, steel sand are as the spraying derusting abrasive medium mostly.
Along with to the comprehensive utilization of steel slag resource exploitation, the slag molding sand that utilizes the discarded object that produces in the steelmaking process to develop, its properties of product and processing cost all are better than copper ore, use in a large number in spraying rust cleaning industry at present, and be respond well.
But in the process of actual production slag molding sand, also have the dust content problem of higher, mainly be by analysis by the particle surface dust content higher due to.
1., the molding sand finished product grain size is thin partially
At present mainly adopt double-deck screen shale shaker to divide device to produce the slag molding sand, its production technology is used＜granule content of 0.5mm is bigger as shown in Figure 1, and thin partially particle diameter is distributed with the quality and the cyclic utilization rate (shown in table 1-1) that may influence rust cleaning.
