[0040] Working principle: Embodiment 1: The industrial waste gas is transmitted to the inside of the adjustment component 9 through the intake pipe 1. The motor 11 is started to drive the gear 12 to rotate, thereby driving the overall rotation of the gear ring 10 and the rotating disk 902. During this period, through the setting of the rotating disk 902, the industrial waste gas can be alternately transmitted to the two equalizing holes 904 during the rotation process, and finally transmitted to the telescopic filter components 6 inside the two partitioned housings 14 for filtering work, realizing the alternate operation of the two telescopic filter components 6. When one of the telescopic filter components 6 is working, the inner filter housing 604 is continuously pushed upward by the air pressure to increase the filtering effect. At the same time, when the other telescopic filter component 6 is in the non-working stage, the inner filter housing 604 will drop due to its own gravity, and during the dropping process, the inner filter housing 604 is cleaned of holes by the metal brush 6062 on the cleaning component 606 to facilitate repeated filtering work;

[0041] Embodiment 2: On the basis of Embodiment 1, through the setting of the trigger member 903, the two trigger members 903 are symmetrically distributed on the perpendicular line of the central connection line of the two connection holes 13 respectively. Then, during the rotation of one of the trigger members 903, one of the touch switches 207 is triggered to connect the solenoid valve 206 on the connection pipe 208 where this touch switch 207 is installed. At the same time, the other trigger member 903 triggers the other touch switch 207 to close the connection of the other solenoid valve 206 in the same way. The two solenoid valves 206 work alternately, realizing that during the operation of one telescopic filter assembly 6, the other telescopic filter assembly 6 is in a non-operating state. The connection pipe 208 at the bottom of the non-operating telescopic filter assembly 6 is connected to the housing 203, and is connected to 101 through the housing 203 and the siphon pipe 202. During this period, due to the diameter difference between 102 and 101, a siphon effect is formed on the siphon pipe 202 during the flow of 101, realizing the formation of suction force inside the siphon pipe 202, and sucking the inside of the non-operating telescopic filter assembly 6 along the housing 203, the connection pipe 208, and the connection hole 13. The dust scraped off by the cleaning component 606 is sucked into the housing 203 and filtered and collected by the collection bin 204. During this period, the solenoid valve 201 is used as a timing switch, so that the siphon effect here is for a fixed time and automatically closes after this time, and the timing start time is less than when the turntable 902 rotates half. The whole process realizes the automatic filtering purpose, and can clean the filter screen on the premise of ensuring the filtering efficiency by using the alternating filtering scheme. The whole process only requires the staff to pour the sundries in the collection bin 204 irregularly, and there is no need to clean the internal telescopic filter assembly 6. It has a high degree of automation, is convenient and easy to operate, and does not require disassembly and cleaning;

[0042] Embodiment 3: On the basis of Embodiment 2, through the setting of the telescopic filter assembly 6, a certain amount of air can be provided inside the partition housing 14 during the siphon negative pressure to prevent the internal space of the housing 7 from being fixed and forming an excessive load of the siphon negative pressure. During this period, the one-way valve 4 is used to prevent the filtered gas from flowing back.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
