The ring plate 52 can block the upper part of the water box 51, so that the water enters the water box 51 and reaches the spray holes of the rotating rod 34 and the scraper 4 for spraying. The sprayed water is mixed and stirred with the sludge, thereby reducing the sludge residue on the filter net. Finally, the sewage generated by cleaning the sludge falls to the bottom of the tower body 1 for storage reaction. After the sewage reacts, the No. 2 solenoid valve is opened at the No. 2 discharge pipe 54 to discharge it.

[0034] A fixing seat 6 is fixedly connected to the support frame 32; a plurality of plug rods 61 are fixedly connected to the end of the fixing seat 6, and the plurality of plug rods 61 are arranged corresponding to the holes of the filter screen; when a large amount of solid impurities remain in the filter holes 16, causing the holes of the filter screen to be blocked, the blocked filter screen rotates to the top of the fixing seat 6, and the electric slider 31 is used to drive the support frame 32 to slide up, and the support frame 32 simultaneously drives the plurality of plug rods 61 fixed on the fixing seat 6 to be inserted into the holes of the filter screen, so as to push out the impurities in the holes of the filter screen, and then clean the solid impurities that cannot be filtered in the filter holes 16, thereby improving the effect of sewage treatment.

[0035] like Figure 1 , Figure 2 and Figure 4As shown, the inner wall of the tower body 1 is rotatably connected to a rotating shaft 7; a plurality of spiral blades 71 are fixedly connected to the outer wall of the rotating shaft 7; a transmission assembly is provided at the bottom of the electric slider 31, and the transmission assembly is used to drive the plurality of spiral blades 71 to stir; after cleaning the filter screens at the plurality of filter holes 16, the sewage generated by the cleaning falls to the bottom of the tower body 1 for storage, and the sewage at the bottom of the tower body 1 can be discharged after a simple catalyst reaction, and the rotating shaft 7 No. 1 is fixed to the bottom position of the tower body 1, and as the electric slider 31 slides, the transmission assembly is driven to operate, and the transmission assembly drives the rotating shaft 7 No. 1 to rotate, and the plurality of spiral blades 71 stir the sewage at the bottom of the tower body 1, thereby improving the reaction treatment effect of the sewage and the catalyst.

[0036] The transmission assembly includes a rack plate 8, a second rotating shaft 81, a gear 82 and a belt 83; the rack plate 8 is fixedly connected to the bottom end of the electric slider 31; the second rotating shaft 81 is rotatably connected to the inside of the tower body 1, and the second rotating shaft 81 is located directly above the first rotating shaft 7; the gear 82 is fixedly connected to the outside of the second rotating shaft 81, and the teeth of the gear 82 and the rack plate 8 can mesh with each other; the belt 83 is sleeved between the second rotating shaft 81 and the first rotating shaft 7; when the electric slider 31 slides up and down, the electric slider 31 can drive the rack plate 8 and the gear 82 to mesh with each other and rotate, and the gear 82 drives the second rotating shaft 81 to rotate during the rotation, so that the belt 83 connected to the second rotating shaft 81 drives the first rotating shaft 7 to rotate synchronously, and finally the multiple spiral blades 71 stir the sewage at the bottom of the tower body 1 to improve the mixing effect of the sewage and the catalyst.

[0037] like Figures 1 to 3 , Figure 6 As shown, the interior of the No. 1 connecting pipe 12 is fixedly connected to a limit plate 9; the inner wall of the No. 1 connecting pipe 12 is slidably connected to a filter frame 91; the bottom end of the filter frame 91 is fixedly connected to a No. 1 filter plate 92 and a No. 2 filter plate 93, and the No. 1 filter plate 92 is located above the No. 2 filter plate 93; before the sewage is subjected to wet oxidation reaction, the sewage is pretreated first, and the sewage is discharged into the No. 1 connecting pipe 12 from the feed port 11, and the filter frame 91 is limited on the limit plate 9 to filter large impurities in the sewage, and the large impurities are filtered on the filter frame 91, and the No. 1 filter plate 92 cooperates with the No. 2 filter plate 93 to continue to perform multi-stage filtration on the sewage that has filtered out the large impurities, thereby improving the pretreatment effect of the sewage.

[0038] A fixing column 94 is fixedly connected to the central end of the filter frame 91; a hook 95 is fixedly connected to the end of the fixing column 94; when large impurities are filtered on the filter frame 91, a hook is used to extend from the feed port 11 into the interior of the No. 1 connecting pipe 12. As the hook hooks the hook 95 and pulls it up, the filter frame 91 connected to the fixing column 94 can be pulled out. After cleaning off the large impurities on the filter frame 91, the filter frame 91 is restored to its original position to continue filtering large impurities, thereby improving the effect of the wet oxidation reaction of sewage.

[0039] Working process: When treating sewage, the tower body 1 is used as the main container for sewage treatment, and the sewage pipe is connected to the two feed ports 11. The sewage is discharged from the two feed ports 11, and the sewage reaches the No. 1 connecting pipe 12 along the inner wall of the tower body 1. Then the sewage enters the two filter holes 16 on the filter plate 15, and the solid impurities in the sewage are filtered through the filter net. The sewage with solid impurities filtered out by the filter net can be sent to the wet oxidation component located below the filter plate 15 for reaction after treatment, thereby improving the effect of sewage reaction treatment. At the same time, when the filter net of the filter hole 16 is clogged by filtering solid impurities for a long time, the output end of the No. 1 servo motor 13 is used to drive the fixed rod 14 to rotate, and the fixed rod 14 drives the filter plate 15 to rotate synchronously, so that multiple filter holes 16 are rotated and switched to ensure that the solid impurities in the sewage are not blocked. The clogged filter hole 16 is taken as the center, and is switched to be connected with the No. 1 connecting pipe 12 above the filter hole 16 and the wet oxidation assembly below the filter hole 16. Multiple filter holes 16 can be switched at any time to filter sewage, and the filter nets in the multiple filter holes 16 can use different filter materials, thereby improving the reaction treatment effect on sewage; when the sewage is reacted and treated, the sewage enters the multiple filter holes 16 for filtration, and the filtered liquid sewage flows down to the inside of the multiple guide pipes 2, and then the sewage reaches the inside of the wet oxidation box 21 for wet oxidation treatment, and the organic matter in the sewage is oxidized into small molecular organic matter or inorganic matter, etc. During the wet oxidation reaction, the No. 1 solenoid valve is closed, and after the wet oxidation reaction is completed, the No. 1 solenoid valve is opened, and finally it can be discharged from the external pipeline at the No. 1 discharge pipe 22;

[0040] When the sewage with sludge is treated, the filter screens at the multiple filter holes 16 filter the solid impurities in the sewage. A large amount of sludge accumulates in the filter holes 16, affecting the filtering effect of the filter screen. The two electric sliders 31 are respectively slid on the inner walls of the two slide grooves 3. The electric sliders 31 drive the support frame 32 to slide down, so that the rotating rod 34 cooperates with the stirring blades 35 to penetrate into the interior of the filter hole 16. The output end of the second servo motor 33 drives the rotating rod 34 to rotate, and the rotating rod 34 drives the multiple stirring blades 35 to stir the sludge in the filter hole 16, thereby ensuring the filtering flow effect of the sewage; when a large amount of solid impurities accumulate on the filter screen in the filter hole 16, the scraper 4 is fixed to the bottom end of the rotating rod 34. As the electric slider 31 drives the scraper 4 to slide down and fit to the filter screen, the output end of the second servo motor 33 drives the scraper 4 connected to the rotating rod 34 to rotate rapidly, and the multiple scrapers outside the scraper 4 The surface scraper can reduce the clogging of the filter screen; when a large amount of sludge is accumulated in the filter hole 16, the excessive sludge will cause clogging of the filter screen. At this time, the introduction of sewage is stopped, and the sludge in the filter hole 16 is stirred by multiple stirring blades 35. Then, the external water pipe is connected to the two flexible water pipes 5. The flexible water pipe 5 is a flexible pipe. Water enters the support frame 32 through the flexible water pipe 5 and passes into the water box 51 through multiple No. 2 connecting pipes 53. Multiple No. 2 connecting pipes 53 fix the ring plate 52 on the water box 51. The ring plate 52 can block the upper part of the water box 51, so that the water enters the water box 51 and reaches the spray holes of the rotating rod 34 and the scraper 4 for spraying. The sprayed water is mixed and stirred with the sludge, thereby reducing the sludge residue on the filter screen. Finally, the sewage generated by cleaning the sludge falls to the bottom of the tower body 1 for storage reaction. After the sewage reacts, the No. 2 electromagnetic valve is opened at the No. 2 discharge pipe 54 to discharge it.

[0041] When a large amount of solid impurities remain in the filter holes 16, causing the holes of the filter to be blocked, the blocked filter rotates to the top of the fixed seat 6, and the electric slider 31 drives the support frame 32 to slide upward, and the support frame 32 simultaneously drives the multiple plug rods 61 fixed on the fixed seat 6 to be inserted into the holes of the filter, so as to push out the impurities in the holes of the filter, and then clean the solid impurities that cannot be filtered in the filter holes 16, thereby improving the effect of sewage treatment;

[0042] After cleaning the filter screens at the multiple filter holes 16, the sewage generated by the cleaning falls to the bottom of the tower body 1 for storage. The sewage at the bottom of the tower body 1 can be discharged after a simple catalyst reaction. The No. 1 rotating shaft 7 is fixed at the bottom position of the tower body 1. As the electric slider 31 slides, the transmission component is driven to operate. The transmission component drives the No. 1 rotating shaft 7 to rotate, and the multiple spiral blades 71 stir the sewage at the bottom of the tower body 1 to improve the reaction treatment effect of the sewage and the catalyst; when the electric slider 31 slides up and down, the electric slider 31 can drive the rack plate 8 and the gear 82 to engage and rotate with each other. During the rotation of the gear 82, the No. 2 rotating shaft 81 is driven to rotate, so that the belt 83 connected to the No. 2 rotating shaft 81 drives the No. 1 rotating shaft 7 to rotate synchronously. Finally, the multiple spiral blades 71 stir the sewage at the bottom of the tower body 1 to improve the mixing effect of the sewage and the catalyst;

[0043] Before the wet oxidation reaction of sewage, the sewage is pretreated first, and the sewage is discharged into the No. 1 connecting pipe 12 from the feed port 11. The filter frame 91 is limited on the limit plate 9 to filter large impurities in the sewage. The large impurities are filtered on the filter frame 91, and the No. 1 filter plate 92 cooperates with the No. 2 filter plate 93 to continue multi-stage filtration of the sewage that has filtered out the large impurities, thereby improving the pretreatment effect of the sewage; when the large impurities are filtered on the filter frame 91, a hook is used to extend from the feed port 11 into the No. 1 connecting pipe 12. As the hook hooks the hook 95 and pulls it up, the filter frame 91 connected to the fixed column 94 can be pulled out. After cleaning the large impurities on the filter frame 91, the filter frame 91 is restored to its original position to continue filtering the large impurities, thereby improving the effect of the wet oxidation reaction of sewage.
