Description
Technical field
The utility model relates to a kind of antiquated sand retracting device.
Background technology
China is a big country in foundry, along with the high speed development of national economy, to China's foundry goods annual production in 2009, has reached 3,530 ten thousand tons, occupies the umber one of World Casting output.China is again the consumption big country of a Modeling Material, because 80% above foundry goods is from sand casting, during due to China's moulding, placer iron is larger, in general, 1 ton of castings of every production can produce approximately 1.2～1.4 tons of antiquated sands, and the cast waste sand of annual discharge can reach more than 3,000 ten thousand tons.So a large amount of discharge cast waste sands, will occupy a lot of antiquated sands place.Extensive use along with the various organic and inorganic binding agents of China, cause the harmful components that contain in antiquated sand more and more, residual aldehyde, phenol, benzene, potassium, isocyanide, sulfide etc. in antiquated sand such as the organic resin binding agent, harmful composition such as residual alkali, phenol in the inorganic binder antiquated sand.The antiquated sand that contains these class harmful components, after discharge, through the rainwater etch, its harmful components will be polluted rivers and lakes, even pollute life water source.The compositions such as the isocyanide especially contained in the strong basicity of water-glass sand and resin sand, phenols, the public hazards that cause are even more serious.In recent years, along with the continuous enhancing of people's environmental consciousness, the increasing of country to the environmental protection law enforcement dynamics, the increase that charges for disposing pollutants are used, all force Foundry Works to carry out regeneration to old sand.
The utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of antiquated sand retracting device.
The utility model solves the technical scheme that its technical problem adopts: a kind of antiquated sand retracting device is characterized in that: comprise connected successively vibrating crushing screening machine, old sand elevator, magnetic separator, hot-method regeneration device, cooling bed, vibratory sieve and fresh sand elevator.
Further, be provided with successively the middle bucket of old sand, screw(-type) feeder between magnetic separator, hot-method regeneration device.
Further, hot-method regeneration device comprises sand preheater, air preheater and roaster, and sand preheater, air preheater are connected with roaster respectively, and the sand preheater is connected with screw(-type) feeder, roaster is connected with cooling bed, and roaster also is connected with gas generator.
The beneficial effects of the utility model are: simple to operate, the old sand recovery utilization rate is high, is easy to promote.
