Casting equipment capable of recycling used sand

Abstract

The invention discloses casting equipment capable of recycling used sand, and relates to the technical field of casting equipment capable of recycling used sand. The casting equipment comprises a grinding cylinder, a first motor is fixedly connected to the top of the grinding cylinder, a rotating shaft is fixedly connected to the output end of the first motor, a first grinding roller is fixedly incup joint to the rotating shaft, the first grinding roller is located in the grinding cylinder, a supporting part is arranged on the grinding cylinder, a screening part is arranged at the bottom of the grinding cylinder, a feeding box is fixedly connected to the side wall of the grinding cylinder, and a magnet plate is arranged in the feeding box. The casting equipment is reasonable in structure,the used sand is evenly smashed through the first grinding roller and a second grinding roller, the needed precisely-cast molding sand particle requirement is met, iron slag in the used sand is removed through the magnet plate, on one hand, the purity of the used sand is improved, and on the other hand, damage to the second grinding roller and the grinding cylinder during grinding due to existence of hard iron slag is prevented.

Description

technical field [0001] The invention relates to the technical field of casting equipment with recyclable old sand, in particular to a casting equipment with recyclable old sand. Background technique [0002] Strictly speaking, casting machinery and equipment is the use of this technology to smelt metals into liquids that meet certain requirements and pour them into molds. After cooling, solidification and cleaning, castings with predetermined shapes, sizes and properties are obtained. Some foundry equipment needs to use foundry sand when casting. [0003] Old sand is relative to new sand. It is produced after at least one casting. In the past, old sand was discarded directly. With the continuous shortage of resources, especially the high specification requirements of precision casting for molding sand, the existing The recovery and treatment effect of used sand is not ideal, and the treatment of used sand is difficult to meet the requirements of precision casting for moldin...

Problems solved by technology

[0003] Old sand is relative to new sand. It is produced after at least one casting. In the past, old sand was discarded directly. With the continuous shortage of resources, especially the high specification requirements of precision casting for molding sand, the existing The recovery and treatment effect of used sand is not ideal, and it is difficult to meet the requirements of precision casting for molding sand particles in the treatment of used sand. Therefore, this application provides a casting equipment with recyclable used sand to meet the demand
