Description
Technical field
The utility model relates to a kind of reclaiming machine for waste sand, especially relates to a kind of compound reclaiming machine for waste sand.
Background technology
When sand casting, 1 ton of foundry goods of every production will produce 1～7 ton of old sand by mistake. The utilization of old sand has two kinds of modes substantially, i.e. reuse after reclamation of return sand and regenerating used. Casting mold is after cast, if there is not irreversible variation in the binding agent in most of molding sand, as long as remove impurity, through suction ash cooling and again mixed system just can recover the original performance of molding sand, this processing mode is called reclamation of return sand, generally only has the molding sand ability reuse of clay bonding. With sand mold and the core (as sand mold and the core made with oil-sand, water-glass sand and various resin sand) of chemical mode sclerosis, the sclerous reaction of its binding agent is irreversible, the reuse simply of old sand in this case, failed sand grain surface adhensive membrane need to be removed, make its performance of substantially recovering roughing sand, this processing mode is called regenerating used. In clay sand mold, press close to the molding sand of cast(ing) surface, after high temperature action, clay has become dead clay, can not recover cementitiousness again. Such clay-bonded sand also must be processed through regeneration could reuse.
Regenerating used has wet method, Re Fa and 3 kinds of methods of dry method. Wet reclamation is more effective for the water-soluble old sand of adhensive membrane energy, is generally used for water-glass sand. Thermal reclamation must be heated to old sand more than 800 DEG C, and the binding agent of inefficacy is burnt, and for inorganic binder poor effect, is applicable to resin sand. Dry reclamation is applicable to the old sand that adhensive membrane is more crisp, is used for regenerating resin sand old sand.
The application relates to a kind of dry reclamation equipment. In prior art, the equipment that dry reclamation adopts is simple, and the scope of application is little, and regeneration effect is undesirable.
