Description

Technical Field

[0001] The utility model relates to the technical field of Fenton reactors, in particular to an automatic intermittent Fenton reactor. Background Art

[0002] The Fenton reactor is a chemical reactor used for wastewater treatment, mainly used to degrade wastewater containing biodegradable organic matter. The main components of the Fenton reactor include the reactor body, feed port, discharge port, agitator, external control system, etc. The Fenton reactor has the advantages of high wastewater degradation efficiency, fast reaction rate, and simple operation. Since a large amount of hydrogen peroxide and iron ions need to be added to the reactor, it consumes more energy. In addition, iron mud and sediment will be produced during the reaction process, which needs to be treated and cleaned.

[0003] After searching, the patent document with publication number: CN219429801U discloses an automatic intermittent Fenton reactor, which is used in conjunction with a stirrer and multiple dosing devices. The stirring rod sequentially stirs and mixes the liquid after dosing, and finally the material in the reactor is lifted by the discharge pump to the filter press for filtration treatment. In actual use, when the stirrer is stirring, the liquid is prone to form a laminar flow phenomenon, resulting in poor mixing efficiency of the reagents, and increasing the difficulty of stirring the bottom liquid of the reactor. The precipitation in the reactor is prone to form dirt and adhere to the inner wall of the reactor. When it needs to be processed and cleaned, the above device needs to be opened for manual cleaning, which is time-consuming and laborious. Therefore, we propose an automatic intermittent Fenton reactor to solve the above problems. Utility Model Content

A limiting ring 7 is rotatably connected to the inner wall of the annular groove. A plurality of balls are arranged on the outer wall of the limiting ring 7. The balls reduce the friction between the limiting ring 7 and the annular groove. The limiting ring 7 assists the turntable 8 to rotate.

The equipment frame 19 assists the shaft body 21 and the driving rod 23 to rotate.

[0026] A cleaning mechanism is arranged on the outer wall of the turntable 8. The cleaning mechanism includes two vertical rods 12. Two vertical holes are opened on the outer wall of the turntable 8. The outer walls of the two vertical rods 12 are respectively slidably connected to the inner walls of the two vertical holes. The tops of the two vertical rods 12 are both fixedly connected with adjusting disks 10. Rotating the adjusting disks 10 makes the vertical rods 12 rotate.

[0027] Two threaded holes 9 are opened on the top of the turntable 8. Assembly holes are opened on the outer walls of the two adjusting disks 10. A bolt 11 is threadedly connected to the inner wall of the assembly hole. One end of the bolt 11 is located in one of the threaded holes 9. The bolt 11 fixes the adjusting disk 10 on the turntable 8.

[0028] Scrapers 13 are fixedly connected to the outer walls of both vertical rods 12. Crossbars 14 are fixedly connected to the bottoms of both vertical rods 12.

[0030] A stirring mechanism is provided inside the reactor housing 1. The stirring mechanism includes a vertical shaft 17. The bottom of the turntable 8 is fixedly connected to the top of the vertical shaft 17. The bottom of the vertical shaft 17 penetrates through the top of the equipment frame 19 and is fixedly connected to a main gear 18.

[0031] A shaft body 21 is rotatably connected inside the equipment frame 19. Two bearings are fixedly sleeved on the outer wall of the shaft body 21.

A plurality of stirring blades 24 are fixedly connected to the outer wall of the driving rod 23. The rotation of the driving rod 23 causes the plurality of stirring blades 24 to stir the liquid.

[0032] Working principle: During use, the sewage pump pumps the wastewater into the reactor housing 1. The chemical agent is transported into the multiple T-shaped chemical feeding pipes 25 through an existing pump body, and enters the reactor housing 1 through the multiple T-shaped chemical feeding pipes 25. The motor 3 operates to drive the turntable 8 to rotate. The rotation of the turntable 8 drives the two vertical rods 12 and the vertical shaft 17 to rotate. The rotation of the two vertical rods 12 causes the two scraping plates 13 to stir the liquid, and the rotation of the vertical shaft 17 causes the main gear 18 to drive the first driven gear 20 and the shaft body 21 to rotate. The rotation of the first driven gear 20 drives the second driven gear 22 to rotate. The rotation of the second driven gear 22 drives the driving rod 23 and the multiple stirring blades 24 to rotate. Due to the meshing relationship, the rotation direction of the second driven gear 22 is opposite to that of the turntable 8, avoiding always rotating in one direction when stirring the liquid, thereby avoiding the generation of laminar flow phenomenon and uniformly mixing the liquid. At the same time, the rotation of the vertical rod 12 drives the cross bar 14 to rotate, mixing the liquid at the bottom and reducing sediment generation. When cleaning the inside of the reactor housing 1, rotate the bolt 11 to release the position fixation of the adjustment plate 10, rotate the adjustment plate 10 to rotate the vertical rod 12 by 180 degrees. The rotation of the vertical rod 12 causes the scraping plate 13 to fit onto the inner wall of the reactor housing 1. Then, screw the bolt 11 into another threaded hole 9 through the assembly hole to fix the vertical rod 12 on the adjustment plate 10. The scraping plate 13 rotates to clean the inner wall of the reactor housing 1, and the two cross bars 14 partially clean the bottom inner wall of the reactor housing. And the water pump operates to transport water into the reactor housing 1 through the flushing pipe. Finally, the sewage is discharged from the sewage discharge pipe 5.
