An oily sewage treatment device according to claim 8, wherein a side limiting component (4) is rotatably mounted on one side outer wall of the casing (5), the side limiting component (4) is used for stabilizing and limiting one side of the filtering component (8), the side limiting component (4) comprises a rotating shaft (43), the rotating shaft (43) is rotatably mounted on one side outer wall of the casing (5), one end of the rotating shaft (43) is fixedly provided with a side limiting piece (42), one side outer wall of the side limiting piece (42) is fixedly provided with a rotating head (41), and the other side outer wall of the side limiting piece (42) is tightly contacted with and extruded from the side wall of the sealing side plate (83).

10. The method of using an oily wastewater treatment device according to any one of claims 1-9, comprising the steps of:

s1, when sewage is treated, the sewage is led into the equipment through the water inlet (3), the sewage can be subjected to preliminary filtration through the filter component (8), the adsorption material in the filter component (8) can adsorb oil stains in the sewage, meanwhile, the impurity of the sewage can be filtered and left on the filter component (8), the stirring component (2) is started at the moment, the stirring component (2) can drive the installation main shaft (24) to rotate, the installation main shaft (24) can drive the driving worm disk (22) and the stirring main plate (25) to rotate, the stirring main plate (25) can stir water, and at the moment, the sewage treatment agent is added into the equipment through the treatment agent pipe (1) to treat the water;

s2, when the driving worm disk (22) rotates, the driving worm disk can drive the reciprocating screw (71) with the driven worm sleeve (73) to rotate, when the reciprocating screw (71) rotates, the two cleaning assemblies (72) on the driving screw can be driven to reciprocate, when the cleaning assemblies (72) move, the cleaning scraping plate (724) can effectively scrape dirt remained on the upper surface of the filter plate (81) to two sides, the filter plate (81) is prevented from being blocked due to dirt accumulation, meanwhile, when the cleaning scraping plate (724) moves, the cleaning scraping plate (724) can automatically deviate by a certain angle through the mounting shaft (726), so that the flexibility of the cleaning scraping plate (724) is improved, and the cleaning effect of the cleaning scraping plate (724) is improved;

s3, when the stirring main board (25) rotates, sewage can generate certain pressure on the outer surface of the stirring blade (27), the stirring blade (27) after being pressed can automatically rotate, so that the stirring effect of the stirring main board (25) on a water body can be effectively improved, the using effect of equipment is further improved, meanwhile, the cleaning side piece (23) can be synchronously driven to rotate when the main shaft (24) is installed to rotate, the upper surface of the cleaning side piece (23) can realize the mutual combination of the synchronous cleaning effect on the lower surface of the filter plate (81) and the work of the circulating cleaning mechanism (7), and the cleaning effect on the filter plate (81) is further improved;

s4, when the filter component (8) needs to be disassembled, the side limiting piece (42) can be directly rotated through the rotary head (41), the side wall of the side limiting piece (42) and the side wall of the sealing side plate (83) lose contact, at the moment, the side top spring (82) loses limitation, the filter plate (81) can be effectively lifted by one distance, the filter component (8) can be directly pulled out through the side handle to be replaced, the filter component (8) is reinserted into the equipment slot during subsequent installation, and the rotary side limiting component (4) can be positioned for the filter component (8).
