[0002] In the existing technology, there are some inconveniences in the operation of the pretreatment equipment for oil-containing waste gas used in foundry enterprises. First of all, it is usually not convenient to replace the filter layer in the existing equipment. Since the filter layer is a key component in the pretreatment equipment and is responsible for capturing and filtering oil particles in the waste gas, it needs to be replaced regularly to maintain the filtering efficiency of the equipment. However, the existing equipment often lacks an effective quick replacement mechanism, resulting in a cumbersome and time-consuming replacement process, which affects the production efficiency and the continuous operation of the equipment.

[0003] Secondly, there are also problems with the existing pretreatment equipment for oil-containing waste gas in discharging oil. During the casting process, the oil in the waste gas accumulates on the filter layer and needs to be discharged regularly to prevent blockage and affect the normal operation of the equipment. However, the existing equipment is often not efficient enough in discharging oil, and may require manual intervention or the use of additional equipment to assist in discharging oil, which not only increases the operation difficulty but also may cause secondary pollution of the oil.
