Environment-friendly recovering device for used foundry sand

Abstract

The invention discloses an environment-friendly recovering device for used foundry sand. The environment-friendly recovering device comprises a fixed base, an inclined conveying belt support, a sintered layer removing box, a motor, polishing gears, a used sand deploying tower, a water pump, crushing and extruding rollers, a used sand mill, a rubbing roller and a rubbing rotation shaft, wherein the inclined conveying belt support is arranged on the fixed base and is connected to a conveying belt through a conveying belt roller, and the right end of the inclined conveying belt support is connected to the sintered layer removing box; the motor is arranged in the slant angle formed by the fixed base and the inclined conveying belt support, and a motor rotation shaft is arranged in front of the motor and is connected to the conveying belt roller through a belt; a bearing plate is arranged on the lower side of the sintered layer removing box, and the lower side of the bearing plate is connected to the fixed base through bearing supporting rods. The environment-friendly recovering device for the used foundry sand is high in automation degree, sanitary and friendly to environment and saves a lot of manpower and material resources, the utilization rate of the used sand is high, and the treatment efficiency of the used sand can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to an environment-friendly casting old sand renovation device. Background technique [0002] Today, with the vigorous development of various chemically bonded sands, clay green sand is still the most important molding material. Its wide application range and large consumption are unmatched by any other molding materials. In casting, most of the foundry sand used is refurbished from old sand and reused. By removing part of the used old sand that cannot be reused, the old sand is then reused. [0003] At the present stage, when treating old sand, most of them remove the high-temperature condensed part of the surface of the old sand and then reuse it. However, when the old sand is treated in this way, too much old sand is removed, resulting in raw materials waste, and will produce smoke when removing the unusable part in the old sand, which will pollute the environment, so there are s...

[0003] At the present stage, when treating old sand, most of them remove the high-temperature condensed part of the surface of the old sand and then reuse it. However, when the old sand is treated in this way, too much old sand is removed, resulting in raw materials waste, and when removing the unusable part of the old sand, it will produce smoke and pollute the environment, so there are serious deficiencies in the existing technology, and we need to innovate the existing technology
