Description

Technical Field

[0001] The utility model relates to the technical field of a drum sand-falling machine, in particular to an energy-saving structure of a sand-falling cooling drum. Background Art

[0002] The drum sand-falling machine is composed of a front drum body, an initial sand-falling section, a rear drum body, and a final sand-falling section. Due to the addition of the initial sand-falling section, the old sand fed into the drum together with the casting can be separated in the initial sand-falling section, so the collision chance of the casting in the subsequent process can be increased, which is conducive to shaking off the old sand from the surface of the casting and breaking up the large sand group, thereby improving the sand-falling effect. When forming the drum sand-falling machine, a sand-falling cooling drum is required;

[0003] When the current sand-falling cooling drum is used, the worker puts the casting into the drum, then turns on the external power supply of the drum, and then uses air cooling or internal water mist spraying to cool the casting, thereby completing the processing of the casting.

[0004] When the traditional falling sand cooling drum is in use, it mostly adopts air cooling or direct internal water mist spraying for processing operations, and does not have a water recovery and recycling structure. In order to prevent the water source from flowing out of the drum, the amount of water mist sprayed is small, which makes the cooling efficiency low. In order to complete the processing requirements, a long time of operation is required, which leads to low overall processing efficiency and a large waste of energy such as electricity, which brings inconvenience to people's use.
