Energy-saving salt core salt recovery equipment

Abstract

The invention discloses energy-saving salt-core salt recovery equipment. The energy-saving salt-core salt recovery equipment comprises a core washing mechanism, a dehydration mechanism, an evaporation mechanism and a circulating mechanism, wherein the core washing mechanism is provided with a water tank, a product, a sand collecting plate and a concentrated liquid valve; the dehydration mechanism is provided with a dehydration barrel, a stirrer, a salt water separation drier, a furnace gas drying valve, a liquid outlet valve and a salt outlet valve; the evaporation mechanism is provided with an air compressor waste heat evaporator, a condenser and a solvent tank; the circulating mechanism is provided with a circulating valve, a circulating pump and the like. A salt core in the product is dissolved and removed through a core washing nozzle; by switching the circulating valve and a recycling valve on a liquid inlet pipe of the circulating pump, washing feeding is ensured; saturated salt liquid is put into the dehydration mechanism through the concentrated liquid valve, a solvent is put into the saturated salt liquid, and the saturated salt liquid is stirred and dehydrated through the stirrer, so that salt in the salt liquid is crystallized and precipitated; the tail gas of an aluminum melting furnace is fed through the furnace gas drying valve, and the separated crystallized salt is dried and is put into a salt storage barrel; separation liquid is distilled through the air compressor waste heat evaporator, so that the solvent and low-salt water are separated and reused. The energy-saving salt-core salt recovery equipment is water-saving, energy-saving and low in cost.

Description

technical field [0001] The invention relates to the field of aluminum alloy casting, in particular to recovery equipment for energy-saving salt core salt. Background technique [0002] Automobile turbocharger is an energy-saving and emission-reducing product to improve the power performance of automobiles. The market demand is constantly increasing. The cooling flow passage of its aluminum alloy compressor casing product needs to use salt core, but the recovery of salt core salt is energy-intensive by volatilization method. Water is expensive to recycle. Contents of the invention [0003] In view of the above problems, the present invention provides an energy-saving salt core salt recovery equipment, which uses low boiling point solvents to separate salt liquids, uses waste heat to recover solvents, and dries to recover salt, effectively reducing recovery costs. [0004] According to the present invention, an energy-saving salt core recovery equipment includes a core wash...
