Evanescent mode foundry sand treatment device

Abstract

The invention discloses an evanescent mode foundry sand treatment device, which comprises a platform, wherein a left baffle plate is arranged at one end of the platform, and a right baffle plate is arranged at the other end of the platform; a transmission belt is arranged on the platform; a material feeding box is arranged above the transmission belt; the inner wall of the material feeding box isof a hollow structure; an electric heater is arranged inside the inner wall of the material feeding box; a material outlet is formed in the bottom of the material feeding box; the end face of the platform is provided with a connecting frame; the bottom of the connecting frame in a transverse direction is fixedly connected with a connecting plate; an electromagnet is arranged below the connecting plate; a rotating shaft is arranged on the outer side of the platform; the bottom of the rotating shaft is connected with a rotary motor through a shaft coupler; the end face of the rotating shaft is fixedly connected with a material collection box; a left electric heater is arranged on the left baffle plate; a right electric heater is arranged on the right baffle plate. The evanescent mode foundrysand treatment device can fully automatically treat foundry sand and effectively solves the problems that the existing foundry sand treatment work is low in treatment efficiency and poor in treatmenteffect.

Description

technical field [0001] The invention relates to a sand treatment device for lost foam casting, which belongs to the field of lost foam casting Background technique [0002] Lost foam casting, also known as full mold casting, is a full mold casting in which foam plastic molds use binder-free dry sand combined with vacuum pumping technology. It is to bond and combine foam models similar in size and shape to castings to form model clusters, brush refractory paint and After drying, it is buried in dry quartz sand for vibration molding, pouring under negative pressure to vaporize the model, liquid metal occupies the position of the model, and solidifies and cools to form a new casting method; after the lost foam casting is completed, the mold sand is cast The process is affected by the vaporization of the model and the metal liquid, which causes the molding sand to be wetted by water vapor after casting and contains metal particles inside. If the molding sand after casting is use...
