Abstract

The invention discloses a sand processing cooling system for lost foam casting. The system comprises a processing tank, an isolation baffle plate, linkage shafts and fixed convex bars, wherein an airblower is mounted on the left side of the processing tank; a feeding hopper is mounted on the upper surface of the processing tank; a discharging hole is formed in the surface of the feeding pipe; a water inlet pipe is arranged on the upper surface of the processing tank; the outer side of the isolation baffle plate is mutually connected with an inner wall of the processing tank; an air exhaust pipe and a driving motor are mounted on the right surface of the processing tank; a driving shaft connected with the left side of the driving motor penetrates through a right wall of the processing tank; the two sides of the linkage shafts are both connected with fixed discs; a discharging hopper is mounted under the processing tank. By adopting a sand temperature cooling system for sand processing,air transmission and air transmission treatment on an inner part of the processing tank can be carried out through the air blower and a water inlet pipe, so that air current in the processing tank isincreased, a temperature from the sand surface is conveniently taken away, and a dust raising plate conveniently raises up sand so as to increase contact area of the air and sand grains, and therefore, a heat dissipation effect is improved.

Description

technical field [0001] The invention relates to the technical field of lost foam casting, in particular to a sand treatment cooling system for lost foam casting. Background technique [0002] Lost foam casting is to bond and combine paraffin or foam models similar in size and shape to castings to form model clusters. After brushing refractory paint and drying, they are buried in dry quartz sand for vibration modeling, and poured under negative pressure to make the model gas It is a new casting method in which liquid metal occupies the position of the model, solidifies and cools to form a casting. During casting, the temperature of the sand is as high as hundreds of degrees Celsius, and it needs to be cooled before it can be used again. The existing cooling system has the problem of low cooling efficiency, and during cooling, due to the problem of uneven air outlet, resulting in After feeding, the temperature of some local sand surfaces is too high.
