During the replacement process, workers usually need to use auxiliary tools such as ladders or lifting platforms to climb to a higher position to disassemble the equipment casing, manually remove the old filter element, and then install a new filter element to restore the sealing state of the equipment. This method is not only time-consuming and labor-intensive, but also has low work efficiency. In the process of removing the old filter element from the equipment, it may cause pollutants to spread, thereby polluting the air in the clean room and destroying the dust-free environment that has been established.

[0030] Sealing pads are provided at the top and bottom of the filter element (existing technology). Initially, a filter element is placed in the placement frame 2, and the two sealing pads on the filter element will fit with the inner wall of the placement frame 2 to form a sealing structure to ensure the normal operation of the filter element in the placement frame 2; a filter element is also placed on the right side of the top of the bottom plate 3, and the filter element is located between the two positioning plates 36. The sealing pad at the top of the filter element will fit with the bottom of the pressure plate 5, and the sealing pad at the bottom of the filter element will fit with the top of the bottom plate 3 to form a sealing structure to ensure that the filter element placed on the top of the bottom plate 3 is not polluted by the external environment. A plastic packaging bag is sleeved on the outside of the fixed frame 10. Since the length of the plastic packaging bag is greater than the width of the fixed frame 10, the plastic packaging bag is in a wrinkled and stacked state on the outside of the fixed frame 10, and the roller 35 is affected by the plastic packaging bag. The extrusion will slightly deviate in the direction away from the fixed frame 10, and the reset torsion spring 34 is in a deformed state. Under the elastic force of the reset torsion spring 34, the roller 35 can press the plastic packaging bag, so that the plastic packaging bag can be fixed on the outside of the fixed frame 10; when the outside air enters the placement frame 2 through the air inlet pipe 001, the filter element in the placement frame 2 can filter the air, and the filtered air can enter the clean room to ensure a dust-free environment in the clean room; when the filter element needs to be replaced, the push plate 8 can be driven to move to the left by the first electric push rod 9, and the push plate 8 can move the filter element placed on the top of the bottom plate 3 to the left. Under the limiting and guiding action of the positioning plate 36, the filter element placed on the top of the bottom plate 3 can accurately pass through the feed port 201 and enter the placement frame 2, and can The old filter element in the placement frame 2 is pushed to move to the left, so that the old filter element can pass through the discharge port 202 and enter the fixed frame 10, until the new filter element is completely aligned with the placement frame 2. At this time, the old filter element will be completely separated from the placement frame 2, and the left end of the old filter element will protrude from the left side of the fixed frame 10, so as to push the left end of the plastic packaging bag on the outside of the fixed frame 10 to move to the left. Since the roller 35 always presses the plastic packaging bag, the plastic packaging bag separated from the fixed frame 10 will be wrapped flatly on the outside of the old filter element. Then, the push plate 8 is driven to move to the right and reset by the first electric push rod 9. The new filter element can take over the filtering work of the old filter element. At the same time, the sliding clamps 26 on the front and rear sides can be driven by the third electric push rod 27 to move to the side close to each other, so that the two sliding clamps 26 clamp the old filter element, and then The guide plate 25, the sliding clamp plate 26 and the third electric push rod 27 are driven to move to the left by the electric slide rail 24. The sliding clamp plate 26 can pull the old filter element and the plastic packaging bag to move to the left, so that the old filter element is completely separated from the fixed frame 10. At this time, the old filter element is completely wrapped by the plastic packaging bag. Then, the second electric push rod 22 drives the upper and lower mounting plates 21 to move toward the side close to each other. The mounting plates 21 can drive the upper and lower hot melt sealers 23 to move toward the side close to each other. When the upper and lower hot melt sealers 23 are attached, the hot melt sealers 23 can perform hot melt sealing on the plastic packaging bag. Then, the fourth electric push rod 29 drives the connecting rod 30 and the second cutter 31 to move downward, so that the second cutter 31 can pass through the two straight holes 2101.The first cutter 28 cooperates with the first cutter 28 to cut the middle of the hot-melt seal of the plastic packaging bag, so that the left and right ends of the plastic packaging bag wrapped around the old filter element are both sealed, and the left end of the plastic packaging bag remaining outside the fixed frame 10 is also sealed, which is convenient for the plastic packaging bag to package the next old filter element. Then, the fourth electric push rod 29 drives the connecting rod 30 and the second cutter 31 to move upward and reset, and then the second electric push rod 22 drives the upper and lower mounting plates 21 to move away from each other and reset. The mounting plates 21 can drive the upper and lower hot-melt sealers 23 to move away from each other and reset, so that the hot-melt sealers 23 are separated from the plastic packaging bag. Then, the sliding clamps 26 on the front and rear sides are driven by the third electric push rod 27 to move to the side away from each other to reset, so that the sliding clamps 26 can loosen the packaged old filter element, so that the packaged old filter element is placed on the top left side of the bottom plate 3, and finally the driving motor 13 drives the rotating rod 12 to rotate, and the rotating rod 12 can drive the winding wheel 14 to rotate to release the wire rope 15, so that the bottom plate 3 can move downward due to gravity and separate from the shell 1. At this time, the shell 1 and the placement frame 2 remain stationary, and the new filter element can continue to filter the air entering the clean room in the placement frame 2 without affecting the dust-free environment in the clean room. The bottom plate 3 can drive the packaged old filter element, the fixed frame 10, the vertical rod 17 and the positioning The plate 36 moves downward to separate the vertical rod 17 from the conical sleeve 16. At this time, the wire rope 15 can slide through the inside of the conical sleeve 16. Then the packaged old filter element is taken away manually, and a new filter element is placed between the two positioning plates 36. The positioning plates 36 play a positioning role to ensure that when the filter element is replaced, the new filter element can move to the left and accurately pass through the feed port 201 into the placement frame 2. At this time, if the plastic packaging bag on the outside of the fixed frame 10 has been used up, a new plastic packaging bag can be manually put on the outside of the fixed frame 10. Each plastic packaging bag can be used at least three times. Finally, the driving motor 13 drives the rotating rod 12 to reverse, and the rotating rod 12 can drive the winding wheel 14 to reverse the wire rope. The rope 15 is wound up, and the steel wire rope 15 can drive the vertical rod 17 to move upward and reset, so as to drive the bottom plate 3 to move upward and reset. The bottom plate 3 can drive the fixed frame 10, the positioning plate 36 and the new filter element to move upward, and then the vertical rod 17 can be inserted into the conical sleeve 16. Under the cooperation of the conical sleeve 16 and the vertical rod 17, the bottom plate 3 can be accurately aligned with the bottom of the housing 1, and the top of the new filter element can contact the top of the pressing plate 5 to form a sealing structure to seal and store the new filter element. In this way, the filter element can be automatically replaced, and the old filter element can be automatically sealed and packaged to prevent the pollutants on the old filter element from spreading and destroying the dust-free environment in the clean room. There is no need for workers to perform high-altitude operations, and the safety is relatively high.
