[0029] In this embodiment, four sets of stop blocks 7 are symmetrically arranged about the center of the mounting ring 1. All four sets of stop blocks 7 are tightly fitted with the upper retaining ring 5. When the groove 6 does not coincide with the stop block 7, the upper retaining ring 5 can be fixed by the stop block 7.

[0030] In this embodiment, the groove 6 and the stop block 7 are adapted to each other. By rotating the upper stop ring 5, the groove 6 on the upper stop ring 5 is aligned with the stop block 7. Then, the upper stop ring 5 is pulled up, and the filter element 3 can be pulled up and taken out from the inside of the mounting ring 1.

[0031] Example 2

[0032] Based on Example 1, the present invention provides a preferred embodiment for an environmentally friendly exhaust outlet in a power plant, for example... Figures 1 to 5 As shown: A connecting ring 9 is fixedly connected to the surface of the mounting ring 1. A slide rod 10 is slidably connected inside the connecting ring 9. Two sets of nuts 11 that fit with the top and bottom of the connecting ring 9 are threadedly connected to the surface of the slide rod 10.

Then, tighten the two sets of nuts 11 to fix the sliding rod 10, thereby fixing the clamping ring 15 and realizing the installation and fixation of the device.

[0036] The working principle and usage process of this utility model are as follows: First, install the exhaust port by placing the mounting ring 1 at the smoke outlet position. Then, rotate the control ring 12 along the inner slide of the connecting ring 9. Because the slide groove 13 is inclined, when the slide groove 13 rotates clockwise with the control ring 12, it will apply a pushing force to the mounting ring 1 on the control rod 14. At this time, the control rod 14 will move closer to the mounting ring 1 along the limit rod 16 and finally fit tightly against the surface of the smoke outlet. Then, tighten the two sets of nuts 11 to fix the slide rod 10, thereby fixing the clamping ring 15 and realizing the installation and fixation of the device.

[0037] Next, by setting the upper baffle ring 5 and the lower baffle ring 2, the filter element 3 and the dust removal cloth 4 can be fixed inside the mounting ring 1. The filter element 3 and the dust removal cloth 4 are used to filter the flue gas. When the filter element 3 needs to be replaced, the screw 8 can be unscrewed, and then the upper baffle ring 5 can be rotated to align the groove 6 on the upper baffle ring 5 with the baffle block 7. Then, the upper baffle ring 5 can be pulled up and the filter element 3 can be pulled up and taken out from inside the mounting ring 1. The filter element 3 can be replaced without disassembling the entire equipment.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
