[0029] A rod groove 17 is provided on the inner wall of the filter kettle 1, and a motor groove 171 is provided on one side of the rod groove 17.

[0030] Working principle: When filtering coking wastewater, the coking wastewater is added into the filter kettle 1 through the water inlet pipe 2. At this time, the coking wastewater will fall on the surface of the filter plate 42. As the coking wastewater falls on the surface of the filter plate 42, it passes through the leakage groove 424, and the impurities inside the coking wastewater are isolated from the outside. The initially filtered coking wastewater will continue to flow to the surface of the next group of filter plates 42. With the three groups of filter plates 42, the coking wastewater can be thoroughly filtered. When the filtration is completed, the coking wastewater will fall into the discharge pipe 18 and finally discharged from the drain port 181. As the coking wastewater is discharged, the impurities remaining on the surface of the filter plate 42 will slowly solidify, and then the heating plate 423 can be started to slowly dry the impurities on the surface of the filter plate 42 to form a filter cake. When the filter cake is dried, the motor 41 can be started to allow the driving rod 411 to flip the filter plate 42 so that the filter plate 42 is in a vertical state. Then the motor 4272 can be started to allow the roller 4274 to move the scraper 427. At this time, the scraper 427 will scrape the filter cake on the surface of the filter plate 42. Because the filter plate 42 is in a vertical state, the scraped filter cake will directly fall into the discharge pipe 18, and then the discharge port 182 can be opened. Finally, if the filter plate 42 needs to be removed, the filter plate 42 is still kept in a vertical state, and then the isolation plate 415 is pulled into the plate slot 419, and then it can be pulled out, thereby achieving the effect of automatically removing the filter cake from the surface of the filter plate 42 at the end of filtration.
