Although the device can effectively filter out fixed particles and dust from large to small in the flue gas transported into the rotary air preheater in sequence, it prevents solid particles and dust in the flue gas from being supported in the rotary air preheater, avoids the phenomenon of blockage inside the device, and at the same time reduces the harm of flue gas emission and can reduce pollution;

[0003] In order to prevent large particles from accumulating on the upper side of the filter plate, this patent opens a corresponding leak on the side wall of the filter plate. However, the leak will cause the flue gas to flow directly from the leak during the normal filtration process, without filtering the flue gas, thereby reducing the filtration quality. Therefore, a rotary air preheater anti-blocking component is provided. Utility Model Content

A cleaning component for cleaning dust on the upper side of the filter plates 7 is provided in the connecting pipe 2.

[0023] The cleaning assembly includes a plurality of fixed plates 10 symmetrically fixedly connected to the outside of the rotating shaft 6, the plurality of fixed plates 10 and the filter plate 7 are matched and arranged relatively, a through groove 12 is provided on the upper side of the plurality of fixed plates 10, a slider 19 is slidably connected in the through groove 12, a moving rod 20 is slidably sleeved in the slider 19, the moving rod 20 runs through the slider 19, a brush plate 21 is fixedly connected to the lower side of the moving rod 20, and the brush plate 21 is located on the upper side of the filter plate 7 and abuts against the filter plate 7;

[0024] A sealing assembly for the leak 8 is also provided in the connecting pipe 2, and the sealing assembly includes a plurality of fixed arc plates 9 fixedly connected to the inner side of the connecting pipe 2, the plurality of fixed arc plates 9 and the filter plate 7 are matched and arranged relatively, a fixed rod 11 is fixedly connected to the lower side of the plurality of fixed arc plates 9, a moving cylinder 14 is slidingly sleeved on the outer side of the fixed rod 11, a baffle 16 is fixedly connected to the lower side of the moving cylinder 14, and the baffle 16 and the leak 8 are arranged relatively;

[0025] The moving cylinder 14 is fixedly connected to the fixed arc plate 9 via the first spring 13, so that the baffle 16 is always located in the leak 8 under normal circumstances;

[0026] The side wall of the moving cylinder 14 is fixedly connected with a moving arc plate 15, and the lower side of the moving arc plate 15 is fixedly connected with an arc baffle 17. The arc baffle 17 and the fixed plate 10 are arranged opposite to each other, and the corners of the arc baffle 17 are rounded. When the fixed plate 10 is driven to rotate by the rotating shaft 6, when the fixed plate 10 and the arc baffle 17 are against each other, the arc baffle 17 is driven to move upward, and then the baffle 16 is driven to move upward, so that the baffle 16 is moved out from the leakage port 8 on the upper side of the filter plate 7, and the leakage port 8 is opened, so that large particles can be leaked from the leakage port 8 and finally fall into the stretching box 4;

[0027] The inner side of the movable arc plate 15 is evenly fixedly connected with a plurality of protrusions 18, and the upper side of the movable rod 20 is fixedly connected with a movable plate 23.

The above-mentioned prior art will not be redundantly described here. During the process, when the fixed plate 10 and the arc-shaped baffle 17 are against each other, the arc-shaped baffle 17 will be driven to move upward, and then the baffle 16 will be driven to move upward, so that the baffle 16 is moved out from the leakage port 8 on the upper side of the filter plate 7. The leakage port 8 is opened, and then large particles can leak out from the leakage port 8 and finally fall into the stretching box 4. At the same time, when the movable plate 23 and the protrusion 18 are against each other, under the action of the protrusion 18 and the second spring 22, the movable plate 23 is shaken, and then the brush plate 21 is driven to slide, thereby reducing the possibility of dust particles sticking to the brush plate 21 and affecting the normal operation of the brush plate 21.
