PRODUCT INTRODUCTION

The resin sand reclamation production line uses the processes of crushing, magnetic separation, secondary regeneration, wind selection, and sieving to regenerate the old sand. According to experience, the resin sand has good collapsibility after pouring, so the line uses manual falling through the grid. The fallen old sand is sent to the vibration regeneration machine by a belt conveyor. The head of the belt conveyor uses a permanent magnet head wheel to separate the iron and iron beans from the sand and sand. The sand is regenerated by vibration. The vibration of the machine is broken, and the rubbing between the sand block and the sand block crushes the sand block into sand particles, and then enters the secondary centrifugal regeneration machine through the bucket elevator, and the sand is rotated and rubbed in the centrifugal regeneration machine at a speed of 28 meters per second. Wipe to remove the film, remove the fine powder, and then remove the impurities in the sand through the vibrating sieve, and then lift it to the sand bin for temporary storage by the bucket elevator. The above set of regeneration treatment is compact in structure and reasonable in design, so that the regenerated sand is qualified. It is required that a continuous resin sand mixing machine be set below the sand silo for the mixing of new sand and small castings. The sand is evenly entered into the sand mixer through the proportional regulator, and then it can be entered through the automatic mixing of the sand mixer. Modeling, which not only enlarges the molding area but also saves the conveying volume of the molding sand. In order to fully remove the ash powder in the old sand, the sand processing system is equipped with a dust removal port at each dust raising point to centrally capture the dust into the dust collector for unification. deal with. A top suction dedusting hood is adopted above the grid, and a mechanical rotary back-blown bag type dust removal is set for the main dust source to ensure dust emission standards and JB9078-96 dust emission concentration standards. At the same time, the working environment is improved. Advanced Japanese original PLC programmable controller, automatic control, reliable interlocking protection system for each operating equipment, making the whole line easy to operate, monitor, restrict and fully protect.
