Description

Technical Field

[0001] The utility model relates to the technical field of steel shot recovery, in particular to a steel shot recovery device for a casting production line. Background Art

[0002] In the steel shot sandbox casting process, steel shot is one of the important materials. Steel shot can be reused, but it will be mixed with mold residues during use. The mold residues need to be removed before the steel shot can be used again.

[0003] After searching: A steel shot recovery device for continuous casting with the authorization publication number CN207806595U includes a sand box turning device for turning over the sand box and restoring it to its original position. A grid plate is provided on one side of the sand box. After the sand box is turned over, the steel shots and the mold shell fall onto the grid plate, and the steel shots pass through the grid holes on the grid plate. The sand box turning device includes a running rail connected to the track for transporting the sand box, the running rail is connected to a turning frame vertically arranged on one side of it, and the turning frame is connected to a box turning machine.

[0004] However, the above-mentioned steel shot recovery device for the casting production line still has some shortcomings. First, the broken mold shell blocks are of different sizes. The mold shell blocks smaller than the steel shots can fall from the gaps in the steel chain plate conveyor belt, but the mold shell blocks larger than the steel shots cannot be screened out, so that the steel shots still contain debris and are not conducive to recycling and reuse. At the same time, dust is easily generated when screening and recovering the steel shots, which will pollute the working environment. Therefore, we propose a steel shot recovery device for a casting production line to solve the above problems. Utility Model Content
