Thermal stripping regenerative furnace discharged sand further heat preservation and rebaking gradual cooling device

Abstract

Relating to casting machinery equipment, the invention provides a thermal stripping regenerative furnace discharged sand further heat preservation and rebaking gradual cooling device. The device is equipped with a heat preservation box, which is composed of a shell plate, a middle rock wool layer, and an inner heat preservation brick layer. One side of the heat preservation box wall is equipped with a sand inlet, the bottom is equipped with sand discharge ports, and the top is equipped with a charge level indicator and an exhaust gas discharge pipe. The box is internally equipped with temperature measurement components. A water cooling waste heat utilization unit and an electric control are disposed at the bottom inside the box. The device provided by the invention has the beneficial effects that: the sand discharged from a thermal boiling stripping regenerative furnace has a temperature up to 600DEG C or above, the sand discharged into the heat preservation box can further undergo rebaking, i.e. a smoldering process, a residual resin membrane especially the residual resin membrane in a surface pit of sand can be thoroughly removed by ablation, thus forming clean and ideal strippedregenerated sand. The thermal stripping regenerative furnace discharged sand further heat preservation and rebaking gradual cooling device provided by the invention is especially for matching the existing thermal stripping regenerative furnace, can make up for the defect of incomplete stripping in existing thermal stripping regenerative furnaces, and has low investment and good effect.

Description

Technical field: [0001] The invention relates to casting machinery and equipment, and mainly relates to a gradual cooling device for discharging sand from a thermal stripping regenerating furnace for heat preservation and then roasting. Background technique: [0002] The used resin sand can be reused after stripping. The used resin sand stripping is generally done by thermal ablation stripping and regeneration in a fluidized furnace. The problem with existing fluidized furnace thermal stripping and regeneration is that the stripping is not enough Completely and thoroughly, the film removal is not clean, especially the resin film in the pits on the surface of the sand often cannot be removed, which will affect the regeneration quality of the reclaimed sand, and further affect the production of the regenerated sand. The quality of the casting. Invention content: [0003] The purpose of the present invention is to provide a thermal method stripping and regenerating furnace t...
