Description

Technical Field

[0001] The invention relates to the technical field of cooling equipment, in particular to cooling equipment for pretreatment of casting blanks. Background Art

[0002] Casting blanks, also known as casting blanks, are unprocessed raw materials or semi-finished products produced during the casting process. During the casting process, casting auxiliary equipment is needed to process the casting blanks, among which cooling treatment of the casting blanks is an indispensable step. The more commonly used cooling equipment in the cooling treatment is the spray cooling equipment. Compared with traditional water cooling equipment, it saves more water resources, and the cooling efficiency of spray cooling is much higher than that of traditional water cooling methods, which can significantly shorten the cooling time of castings. Moreover, it helps to reduce the thermal stress inside the castings and reduce the risk of cracks and deformation. However, it still has certain shortcomings. On the one hand, a large amount of water vapor is generated during the spray cooling process. Failure to limit it will increase the humidity in the workshop and have an adverse effect on the workshop environment and equipment. On the other hand, spray cooling has high requirements for water quality to avoid nozzle clogging or stains on the surface of the casting. Therefore, a filter needs to be set to ensure the water quality. The installation and removal of the filter is very inconvenient, and it is not convenient for the staff to clean or replace it regularly, which makes the staff's work intensity greater.
