[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 This embodiment provides a device for removing aniline pollution from water, comprising a reaction tank 100. A connecting valve 102 is connected to one side of the reaction tank 100. A feed inlet 101 is provided at the top of the reaction tank 100.

[0025] The cleaning component includes an electric push rod 400 fixedly mounted on the surface of the filter box 300, the telescopic end of the electric push rod 400 is fixedly connected to a 7-shaped plate 401, the other end of the 7-shaped plate 401 extends into the inner cavity of the filter box 300 and is fixedly connected to a fixed shell 402, and the inner cavity of the fixed shell 402 is provided with a scraper 407, one end of the scraper 407 contacts the surface of the filter plate 301, through the setting of the cleaning component and the filter box 300, the electric push rod 400, the telescopic end of the electric push rod 400 extends upward, pushing the 7-shaped plate upward, and the scraper 407 connected to the bottom of the 7-shaped plate pushes the impurities attached to the surface of the filter plate 301 upward, so that the impurities are separated from the surface of the filter plate 301, thereby automatically cleaning the surface of the filter plate 301, preventing the filter plate 301 from being blocked, and ensuring the stability of the filtering effect, and the filter plate 301 and the activated carbon plate 302 in the filter box 300 can effectively remove solid impurities and aniline in the sewage, thereby improving the quality of the treated water.

[0026] Furthermore, the mixing assembly includes a driving motor 200 fixedly mounted on the top of the reaction tank 100, the output shaft of the driving motor 200 extends to the inner cavity of the reaction tank 100 and is fixedly connected to a connecting shaft 202, and the surface of the connecting shaft 202 is fixedly sleeved with a plurality of groups of connecting rings 203 arranged at equal distances, and the two sides of the connecting rings 203 are fixedly connected with stirring rods 201. Through the setting of the mixing assembly, the reaction reagents and the sewage are fully mixed, and the setting of the connecting rings 203 and the stirring rods 201 increases the area and intensity of stirring, making the reaction more sufficient and rapid.

[0027] Preferably, two groups of T-tubes 403 are slidably inserted into the surface of the fixed shell 402, and one end of the two groups of T-tubes 403 respectively passes through the fixed shell 402 and is connected to the corresponding side surface of the scraper 407. The surface of the fixed shell 402 is provided with a pushing member for pushing the scraper 407. Through the setting of the T-tube 403, the two sides of the scraper 407 are guided to prevent the scraper 407 from flipping or deflecting when cleaning the surface of the filter plate 301.

[0028] It is worth noting that the pushing member includes a first bolt 404 threadedly connected to the middle surface of one side of the fixed shell 402.

[0031] Working principle;

[0032] First, the wastewater containing aniline is injected into the reaction tank 100, and then according to the amount of the injected wastewater. The corresponding measured reaction reagent is injected into the reaction tank 100, and the driving motor 200 is started at this time. The driving motor 200 drives the connecting shaft 202 to rotate, thereby driving the stirring rods 201 on both sides of the connecting ring 203 to rotate, so that the sewage and the reaction reagent are fully mixed, and then the connecting valve 102 is opened, and the sewage after the reaction is completed flows into the filter box 300, and then passes through the filter plate 301 for filtration and passes through the activated carbon plate 302 for adsorption and filtration of the sewage, and then is discharged to the outside through the outlet pipe 303. When the device is used for a long time, more impurities are attached to the surface of the filter plate 301. The electric push rod 400 is started, and the telescopic end of the electric push rod 400 is extended upward to push the 7-shaped plate upward. The scraper 407 connected to the bottom of the 7-shaped plate 401 pushes the impurities attached to the surface of the filter plate 301 upward to separate the impurities from the surface of the filter plate 301. Then the staff removes the scraped impurities. When it is found that the scraper 407 has a great impact on the filter plate 301 When the contact force decreases, resulting in a decrease in the cleaning force on the surface of the filter plate 301, it is only necessary to tighten the first bolt 404. The screw 406 of the first bolt 404 pushes the scraper 407 outward, thereby increasing the contact force between the scraper 407 and the filter plate 301. When the scraper 407 is severely worn, the staff removes the screw 406 to separate the 7-shaped plate from the fixed shell 402, and then removes the fixed shell 402 from the inner cavity of the filter box 300. Then, the second bolt 408 is removed to release the fixing restriction on the scraper 407, and then the scraper 407 is removed from the inner cavity of the fixed shell 402 and replaced with a new scraper 407. Then, the two sets of T-tubes 403 respectively penetrate the fixed shell 402 and contact the surface of the scraper 407, so that the second bolt 408 penetrates the T-tube 403 and is threadedly connected to the surface of the scraper 407, fixing the scraper 407 to the T-tube 403. At this time, the replacement of the scraper 407 is completed.
