Description
Technical field
The utility model relates to the (sand) reclaimer of the regenerating used that produces for Foundry Production.
Background technology
In the Foundry Production industry, no matter be to adopt the clay-bonded sand casting or adopt the water-glass sand casting, the capital produces a large amount of antiquated sands, also claims old sand, and nearly all resin self-setting sand manufacturing enterprise all is used for phenolic sand molding and coremaking with the resin self-setting sand old sand after the mechanical friction mode is regenerated; Some Enterprises is removed the dead clay mambrane of part sand grain surface by impacting and rubbing clay old sand, and all or part of replacement fresh sand is used for clay-bonded sand; These processing modes are difficult to remove dead clay and the inert coating that sand grain surface coats, and the regeneration effect that reaches is limited, cause casting quality reduction, hydraulic performance decline.Most enterprises just abandon old sand later through several times reuse, again change fresh sand, cause environmental pollution and cost to improve.Along with the raising that casting quality is required, from the angle of economy and environmental protection, regenerating used has become indispensable part in the Foundry Production.
At present, the commonly used reclamation technique method of factory mainly is divided into three major types according to the difference of its equipment operation principle: dry reclamation, wet reclamation, thermal reclamation.Thermal reclamation is by roaster old sand to be heated to 850-900 ℃, to remove the renovation process of flammable residue on the old sand grain, thermal reclamation is good especially to the regeneration effect of organic binder bond sand, residual binding agent removes totally, the Heat stability is good of reclaimed sand can recover former size distribution, but cost is higher, energy consumption is larger, and its use is subject to certain restrictions.Wet reclamation is dissolving, scrubbing action and the mechanical agitation of utilizing water, makes the false breakage of particles in the old sand, and the residual adhensive membrane of sand grain surface dissolves, comes off or removes.The major advantage of wet reclamation is to some water-soluble old sand, good regeneration effect to be arranged, the reclaimed sand quality is good, can make facing sand and use, and the regeneration rate of old sand is high, its major defect is that complex process, floor space are larger, and cost is high, and the problem such as sewage disposal is arranged.But for fear of this difficult problem of regenerating used sewage disposal, the regenerating used multi-steering adopts dry reclamation at present.
That dry reclamation is divided into again is centrifugal, air-flowing type, oscillatory type, reverse-flow etc., the regeneration of centrifugal and air-flowing type is to utilize mechanical centrifugal power and compressed air stream that the old sand grain is accelerated to certain speed, relies between sand grains and hardware or rubbing action regeneration old sand that sand grains is mutual; Oscillatory type regeneration is under the effect of vibration force, the body of filling the old sand piece ceaselessly vibrates, thereby cause impact, friction between the sand lump, and impact, the friction of sand lump and vibrating body inwall, make sand lump breaking, old sand grain obtain regeneration, reverse-flow regeneration be by between the sand grains and the strong friction between sand grains and the member be used for the old sand of regenerating.Above-mentioned these are centrifugal, the operation principle of air-flowing type, oscillatory type and reverse-flow dry reclamation is by making the old sand capsomere produce higher speed, then between old sand particle and old sand particle and between old sand particle and relevant device severe impact, collision occur, thereby make the old sand grain obtain regeneration, so the larger speed of old sand particle is a necessary condition of regenerating used.The demoulding power that these process of regenerating provide is limited, can not remove the residual film on the old sand grain fully, and the quality of reclaimed sand is not too high; Owing to need to provide higher speed for the old sand housing; this just needs equipment that higher intensity is arranged; increased the cost of equipment; high-speed little old sand is quite serious to the wearing and tearing of equipment; the replacement frequency of equipment is higher; also increased the cost of equipment; simultaneously; because the old sand particle is frangible; old sand particle at a high speed mutually impacts, collides, and old sand Particle Breakage phenomenon often can occur, along with the raising of old sand particle demolding rate; required speed, impulsive force and the frictional force of old sand particle is larger, and the Fragmentation Phenomena of the wearing and tearing of element of installation and old sand particle is more serious.
