[0035] In summary, the overall device in use:

[0036] When the filter plate 3 needs to be cleaned automatically, the air inlet pipe 14 and the air outlet pipe 11 are connected to the external pipeline through the flange 15, the fan 16 is started, so that the waste gas generated by the coke oven enters the shell 1 through the air inlet pipe 14 and is filtered through the filter plate 3, so that the filter plate 3 intercepts the impurities in the waste gas, and the filtered waste gas is discharged from the air outlet pipe 11 and enters the subsequent treatment process. When the filter plate 3 needs to be cleaned, the first motor 9 is started, the first motor 9 drives the convex column 10 to rotate, and when the convex column 10 rotates to contact the push plate 7, the convex column 10 pushes the push plate 7 to move as the convex column 10 rotates. The push plate 7 drives the two moving rods 5 to move, the first spring 8 is compressed, the moving rod 5 drives the knocking block 6 to move, so that the knocking block 6 knocks the mounting bracket 2, and the mounting bracket 2 drives the filter plate 3 to vibrate. When the convex column 10 rotates to separate from the push plate 7, the moving rod 5, the knocking block 6 and the push plate 7 move back to the original position under the push of the first spring 8. Thus, the filter plate 3 is repeatedly vibrated, and the dust adhered to the filter plate 3 is vibrated and falls off, thereby cleaning the filter plate 3.

[0037] When the inside of the shell 1 needs to be cleaned, the second motor 18 is started, the second motor 18 drives the gear 19 to rotate, and since the gear 19 is connected with the gear ring 17, the gear ring 17 drives the rotating cover 12 to rotate, the rotating cover 12 drives the two scrapers 13 to rotate, the scrapers 13 contact the inside of the shell 1, thereby scraping and cleaning the inside of the shell 1. Since the shell 1 on one side of the filter plate 3 is inclinedly arranged, the impurities scraped and cleaned fall into the collecting chamber 20 under the action of gravity. The impurities vibrated during cleaning of the filter plate 3 also fall into the collecting chamber 20. The collecting chamber 20 contains water through the water inlet pipe 21. The impurities contact the water to avoid being raised again. When the sewage inside needs to be cleaned, the sewage pipe 22 is opened, so that the sewage flows out.

[0038] When the filter plate 3 needs to be replaced, pull the handle 29, the handle 29 drives the plurality of insertion rods 26 to move, the insertion rods 26 drive the limiting ring 28 to move, and the second spring 27 is compressed. At the same time, the insertion rod 26 is separated from the mounting plate 24 at one end, the mounting plate 24 is pulled, the mounting plate 24 drives the mounting bracket 2 to move out of the mounting slot 23, the mounting bracket 2 drives the filter plate 3 to move out, thereby disassembling the filter plate 3. The mounting bracket 2, the mounting plate 24 and the filter plate 3 are installed in the opposite way.
