Description

Technical Field

[0001] The utility model belongs to the technical field of waste sand screening and recovery devices for casting processing, and specifically relates to a waste sand screening and recovery device for casting processing. Background Art

[0002] Waste sand usually refers to the sand mold or sand core that is formed by the high-temperature metal liquid during the casting process. Since such waste sand contains a lot of impurities and is in large quantities, most factories usually find it difficult to process the waste sand. They often need to choose to pay high processing fees to recycle the waste sand, or to pile up and bury the waste sand in a selected place. Therefore, the existing factories not only waste financial and material resources when processing waste sand, but also greatly affect the sustainable development of the environment.

[0003] In order to facilitate the recycling of waste sand in factories and reduce the cost of waste sand recycling, a variety of waste sand recycling devices have appeared on the market. The waste sand recycling technology adopted by existing wastewater recycling devices generally crushes the waste sand from blocks into particles, then removes impurities through scrubbing and other means, and finally mixes an appropriate amount of new sand to make it meet the standards for secondary use, thereby achieving the purpose of waste sand recycling. For example, a Chinese utility model patent with publication number CN208696223U has disclosed a mixed type foundry waste sand scrubbing and recycling equipment, which includes a base, a box body is provided on the upper end of the base, a feed hopper is installed on the upper end of the box body, and a water inlet pipe is also installed on the side wall of the box body. Two friction rollers are rotatably connected inside the box body, and two first motors are fixedly installed on the outer wall of the box body. The rotating shafts of the two friction rollers both pass through the box body and are fixedly connected to the output rods of the two first motors respectively. An opening is provided on the right side of the box body, and the inner bottom and the opening of the box body both adopt an inclined structure. The upper end of the base is also fixedly connected to a mounting seat and a support seat, and the upper end of the mounting seat is rotatably connected to a transmission rod, and the end of the transmission rod away from the mounting seat is connected to a shovel body, and the shovel body is located inside the inclined structure of the box opening.

[0004] However, the existing waste sand recovery equipment still has certain defects: 1. The above-mentioned mixed casting waste sand scrubbing recovery equipment and some other traditional waste sand recovery equipment do not recycle the sewage during the material recovery process, which easily causes a waste of water resources; 2. It is unable to separate impurities well during the material recovery process, especially the metal impurities contained in most materials, which need to be further removed by other equipment, thereby greatly increasing the equipment investment cost of waste sand recovery; 3. For the washed materials, it is also necessary to use other equipment for secondary treatment and drying, which greatly affects the secondary utilization efficiency of the materials; 4. It is difficult to achieve the purpose of recycling large pieces of materials only by scrubbing; 5. Traditional waste sand recovery equipment also requires manual processing and packaging of the processed finished materials, which is very inconvenient. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a waste sand screening and recovery device for casting processing which can not only crush, clean, transport, dry, separate metal materials and the like on waste sand in sequence, but also treat and reuse the wastewater from cleaning the materials, so as to overcome the above-mentioned defects of the existing waste sand screening and recovery devices for casting processing.
