[0002] A large amount of fly ash is generated during the incineration of garbage. The fly ash collected in the fly ash bin is evenly transported to the ash conveyor by the ash unloading valve, and then the fly ash is transported to the mixer by the ash conveyor. The fly ash is fully mixed with the chelating agent and water in proportion in the mixer to achieve a stabilization treatment effect. After the stabilized fly ash meets the specified requirements, the stabilized fly ash of the mixer is bagged through the ash outlet and then transported to the fly ash temporary storage room. The fly ash ton bags are stacked in the fly ash temporary storage room for storage for 3 to 7 days. After passing the test, they are loaded and sent to the domestic waste landfill for safe landfill. Some fly ash in the fly ash temporary storage room will enter the air with the circulation of air, which not only affects the health of people entering the fly ash temporary storage room, but also easily pollutes the environment when discharged outdoors.

After filtering for a period of time, a certain amount of dust will be attached to the filter screen 3. When the filtering effect becomes poor, the first motor 6 can be used to make the rotating shaft 12 rotate synchronously, so that the rotating shaft 12 on one side of the box shell 1 can reel in the filter screen 3, and the rotating shaft 12 on the other side can stretch the filter screen 3 to adjust the use area of ​​the filter screen 3. At the same time, during the movement of the filter screen 3, the sponge strip 13 can clean and maintain the surface of the filter screen 3, and the sponge strip 13 can be moistened through the water injection pipe 5 to wipe off the fly ash attached to the surface of the filter screen 3, so that the fly ash can form sewage along the water stains and flow into the dirt collecting box 2 below the box shell 1, thereby cleaning the area of ​​the filter screen 3 after use.
