Abstract

The invention discloses an aluminum alloy continuous melting furnace utilizing waste heat to regenerate resin sand, and relates to a melting furnace. The aluminum alloy continuous melting furnace specifically comprises a furnace body and a feeding tower installed at the top of the furnace body, a furnace cover is fixed at the top of the feeding tower, and the side face of the top end of the feeding tower is fixedly connected with one end of an L-shaped discharge flue. A sleeve fixedly sleeves the vertical part of the discharge flue, a sand inlet is formed in the side face of the top end of the sleeve, a discharge port is formed in the bottom of the sleeve, reclaimed sand is discharged through the discharge port, and an extraction opening is formed in the top of the sleeve. According to the aluminum alloy continuous melting furnace utilizing the waste heat to regenerate the resin sand, the waste heat of the melting furnace is utilized, so that the heat utilization rate of the melting furnace is effectively increased, additional resin sand heating equipment is not needed, the purpose of recycling the resin sand is achieved, and the production cost of an enterprise is reduced.

Description

technical field [0001] The invention relates to a melting furnace, in particular to an aluminum alloy continuous melting furnace which utilizes waste heat to regenerate resin sand. Background technique [0002] Resin sand refers to molding sand or core sand that uses synthetic resin as a binder for sand grains. After the mold or core is made of resin sand, the resin undergoes an irreversible crosslinking reaction and solidifies through the action of the curing (hardening) agent, thus giving the mold or core the necessary strength. [0003] In the prior art, resin sand is used as the molding material for low-pressure casting, and the aluminum alloy is melted in a continuous melting furnace, and then the melted aluminum alloy is injected into the resin sand mold. Part of the sand needs thermal regeneration before it can be used, otherwise it can only be treated as waste sand. The traditional thermal regeneration of resin sand is to heat and burn off the residual resin on the...
