Description

Technical Field

[0001] This invention relates to the field of phosphorus recovery technology, specifically to a phosphorus recovery reactor. Background Technology

[0002] In wastewater treatment, common phosphorus removal methods include chemical phosphorus removal and biological phosphorus removal. Chemical phosphorus removal involves adding metal ions to precipitate dissolved phosphorus under specific conditions, transforming it into a solid phosphorus compound, such as magnesium ammonium phosphate (commonly known as "struvite"). This method can effectively recover phosphorus from wastewater. The recovered phosphorus usually exists in the form of solid precipitate. Biological phosphorus removal utilizes the action of microorganisms to allow phosphorus to be taken up by the microorganisms in a dissolved state and separated from the wastewater along with the microorganisms. For example, Chinese invention patent CN115010325B discloses a phosphorus recovery reactor, which relates to the field of wastewater phosphorus removal and recovery technology. It includes a reaction tank, which is equipped with a denitrification and phosphorus removal packing layer and a stirring device located at the bottom of the reaction tank to support the denitrification and phosphorus removal packing layer. The stirring device includes four vertically arranged stirring shafts with stirring blades. The bottom ends of the stirring shafts extend to the bottom of the reaction tank, and each stirring shaft is rotatably connected to the bottom of the reaction tank through a sealed bearing. A belt pulley drive mechanism is connected to each stirring shaft. A first bearing seat is fixedly installed at the top of each stirring shaft. The rotating inner ring of the first bearing seat is sleeved and fixedly connected to the top of the stirring shaft. A support structure is provided at the top of each first bearing seat, and the denitrification and phosphorus removal packing layer is located on the top of each support structure. The stirring device of the present invention can realize the support and fixation of the packing layer and the automatic release of drugs;

[0003] I. While existing biological phosphorus removal methods can meet the needs of use, chemical phosphorus removal methods are still used in daily life. Existing devices mostly involve pouring wastewater into a wastewater tank, adding chemical reagents, stirring, and then pumping out the water to collect the phosphorus-containing compounds after the reaction, which are then processed for phosphorus recovery. However, the chemical reagents need to be fully mixed with the wastewater to achieve maximum efficiency and improve the efficiency of phosphorus removal from wastewater.

[0004] Second, after the reagent is added to the wastewater, most of the particles produced by the mixing reaction sink to the bottom of the water. However, some particles adhere to the wastewater pool after drainage, which not only affects the treatment of the next batch of wastewater, but also makes it difficult to clean the reaction pool, which puts a great burden on manual cleaning.

[0005] Third, after the phosphorus-containing particles are extracted, it is not possible to quickly replace the filter device, resulting in slow wastewater treatment and long replacement time, which affects efficiency. Summary of the Invention

However, chemical reagents need to be fully mixed with wastewater to achieve maximum efficiency and improve phosphorus removal efficiency from wastewater; 2.

Through linkage, it can be accurately positioned for easy installation and disassembly.

[0044] Working Principle: During operation, when wastewater needs to be decomposed, the wastewater is first poured into the semi-circular notch 512 of the fixed circular plate 511 at the top of the separation tank 51. Then, chemical reagents are poured into the wastewater, and the second motor 62 is turned on to drive the stirring rod 63 at the bottom to rotate. The rotation of the stirring rod 63 drives the three sets of stirring blades 64 inside to fully stir the wastewater in the separation tank 51, thereby improving the mixing efficiency. After mixing is completed, the drain outlet 21 is opened by activating the solenoid valve 22 to discharge the phosphorus-removed wastewater. When the mixed phosphorus-containing particles fall through the internal flow limiting plate 513 into the filter membrane 522 at the bottom for filtration, the next filtration can be performed to improve efficiency. When removal or replacement is needed, starting the first motor 334 will drive the bottom main threaded rod 332 to rotate. The rotation of the main threaded rod 332 allows it to rotate in place under the limitation of the limiting sleeve 333. This rotation of the main threaded rod 332 will then drive the centrally mounted main threaded sleeve 331 to rise. As the main threaded rod 332 rises, it will cause the front U-shaped frame 32 and the T-shaped sliders 312 connected at both ends to rise within the T-shaped slide rail 311. The rise of the T-shaped sliders 312 will then drive the inner rotating mechanism 4 and the separation barrel 51 to rise. The separation barrel 51 will rise under the connection of the top connecting block 53. When the C-shaped frame 41 rises to its highest position, the center of the limiting rotating shaft 42 inserted on the left side will be fixed. The second gear 43 contacts the bottom end of the first gear 123. Then, starting the drive box 121 drives the drive shaft 122 to rotate. The rotation of the drive shaft 122 drives the centrally fixed first gear 123 to rotate. The rotation of the first gear 123 engages the second gear 43, causing it to rotate. The rotation of the second gear 43 drives the limiting shaft 42, causing the centrally fixed C-shaped frame 41 to flip backward. The flipping of the C-shaped frame 41, connected by the connecting blocks 53 on both sides of the bottom, flips the separation tank 51, causing the phosphorus-containing particles in the sidewall flow-limiting plate 513 to fall to the bottom. Simultaneously with the flipping of the separation tank 51, the transmission rod 411 inserted in the center of the right-side limiting shaft 43 rotates. The rotation of the transmission rod 411 drives the left... The lateral bevel gear 412 rotates, engaging the vertical bevel gear 413 at the top of the fixed shaft 743. The rotation of the fixed shaft 743 drives the central chain assembly 742 to rotate, which in turn drives the outer side of the secondary threaded sleeve 713 at the top of the rear main limiting assembly 71 to rotate. The rotation of the secondary threaded sleeve 713 causes the secondary threaded rod 711 at the bottom to rise under the limiting bearing 712. Simultaneously, the rotation of the secondary threaded sleeve 713 in the main limiting assembly 71, connected by two sets of conveyor belts 73 at the bottom, raises the two sets of secondary threaded rods 711, separating them from the threaded opening 524 in the internal limiting block 523 of the bottom connecting ring 521.Then, simply unscrew the limiting pin 526 in the bottom connection port 515 of the separator 51 to remove the connecting bottom ring 521 and the filter membrane 522, thus removing the phosphorus-containing particles. The process can then be repeated in reverse.
