A rotating ball 17 is arranged above the exhaust window 16, and the rotating ball 17 is positioned inside the exhaust pipe 10 and is rotationally connected with the exhaust pipe 10.
The rotating ball 17 comprises a sealing part 17 and a hollow part 18, and the sealing part 19 and the hollow part 18 are fan-shaped and are arranged at intervals.
In the present invention, exhaust gas to be treated enters into a gap between the filter bag 3 and the annular seal cover 5 through the filter bag 3, wherein dust contained in the exhaust gas is accumulated on the outer side of the filter bag 3, and filtered gas flows between the filter bag 3 and the annular seal cover 5 and enters into the exhaust pipe 10 through the air outlet 1 provided on the seal cover 9; the rotating ball 17 arranged in the exhaust pipeline 10 is used for controlling the opening and closing of the exhaust pipeline 10, and the filtered gas is normally discharged by controlling the rotating ball 17 to rotate when the hollow part 18 rotates to a certain position, as shown in fig. 1, the exhaust pipeline 10 is unobstructed in front and back; when the sealing part 19 rotates to a certain position, the exhaust pipeline 10 is blocked, air in the pipe is gathered, so that the exhaust window 16 is pushed to rotate, the air enters a gap between the annular sealing cover 5 and the exhaust pipeline 10, and as the air entering amount in the gap increases, the air pressure increases, the swinging window 6 is pushed to open, the air enters the gap between the filter bag 3 and the annular sealing cover 5 from the gap between the annular sealing cover 5 and the exhaust pipeline 10, and the swinging window 6 can hit the filter bag 3 when being opened, so that the filter bag 3 is vibrated, and the ash cake on the filter bag 3 is enabled to fall off.
Also, it is noted that when the exhaust duct 10 is opened, air does not flow between the annular sealing cover 5 and the exhaust duct 10, and thus the internal pressure is greater than that of the exhaust duct 105, so the exhaust window 16 is closed by the internal-external pressure difference and the self gravity, and when the exhaust duct 10 is closed, the internal pressure of the exhaust duct 10 rises, thereby pushing the exhaust window 16 open.
In another preferred embodiment of the present invention, an end cap 22 is fixedly connected to the side of the annular sealing cover 5 away from the sealing cover 9, a connecting portion 21 is disposed on the inner side of the sealing frame 20, and the end cap 22 is in threaded connection with the sealing frame 20 through the connecting portion 21.
In this embodiment, the cage for installing the filter bag 3 is divided into two parts, and the annular sealing cover 5 and the exhaust pipe 10 fixedly connected with the cage can be separated from the outside of the cage through the middle hole of the annular plate 1 by rotating the end cover 22, so that the disassembly and the assembly are more convenient, and the filtration of the filter bag 3 can not be influenced after the annular sealing cover 5 and the exhaust pipe 10 are disassembled.
In a preferred embodiment of the present invention, the free ends of the swing window 6 and the exhaust window 16 are fixedly provided with a stopper 7, and the rotation directions of the swing window 6 and the exhaust window 16 are limited by the stopper 7.
In a preferred embodiment of the present invention, the installation cavity 15 is provided in the exhaust pipe 10, the impeller 14 rotationally connected with the exhaust pipe 10 is provided in the installation cavity 15, the impeller 14 and the rotating ball 17 are respectively and fixedly connected with the driving wheel 23, the driving wheel 23 is located at the outer side of the exhaust pipe 10 and rotationally connected with the exhaust pipe, the two driving wheels 23 are connected by the conveying belt 24, the impeller 14 is driven to rotate in the process of flowing gas in the exhaust pipe 10, so that the driving wheel 23 and the conveying belt 24 drive the rotating wheel 17 to rotate, thereby periodically opening and closing the exhaust pipe 10, no additional power driving is required, and the swinging frequency of the swinging window 6 can be determined along with the treatment capacity of the exhaust gas, the exhaust gas quantity is large, the airflow velocity is accelerated, and the opening and closing frequency of the exhaust pipe 10 is accelerated.
In a preferred embodiment of the present invention, a return spring 13 is fixedly connected to the inner side of the swing window 6, a mounting ring 12 is fixedly connected to a side of the return spring 13 away from the swing window 6, and the mounting ring 12 is fixedly connected to the exhaust pipe 10.
The main function of the return spring 13 is to prevent the swing window 6 from opening when the exhaust duct 10 is open, since the air between the filter bag 3 and the annular seal housing 5 is flowing while the annular seal housing 5 and the exhaust duct 10 are stationary while the exhaust duct 10 is open, the pressure inside the swing window 6 is greater than outside, and thus an inward pulling force is applied by the return spring 13 to overcome the pressure difference.
The foregoing describes one embodiment of the present invention in detail, but the description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
