The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] The following describes a novel UBF anaerobic reactor according to an embodiment of the present invention, with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown in the figure, a novel UBF anaerobic reactor according to an embodiment of the present invention may include a wastewater treatment tank 1, a separation component 2, and an auxiliary filtration component 3.

[0026] Multiple separation components 2 are respectively installed on the sewage treatment tank 1, and auxiliary filtration components 3 are installed on the sewage treatment tank 1, with the filtration end of the auxiliary filtration components 3 located inside the transmission end of the multiple separation components 2.

[0027] It should be noted that an isolation layer 11 is provided on the inner wall of the sewage treatment tank 1 and is located at the bottom of the transmission pipe 211. Furthermore, an outlet pipe 12 and an inlet pipe 13 connected to the interior are provided on the outer wall of the sewage treatment tank 1 and are located above and below the isolation layer 11, respectively. On the one hand, by setting the isolation layer 11, impurities in the wastewater can be filtered. On the other hand, by setting the outlet pipe 12 and the inlet pipe 13, drainage and water supply can be facilitated.

[0028] The separation component 2 includes: a conveying device 21, a separation tank 22, and a wall scraping device 23.

[0029] The transmission end of the transmission device 21 is connected to the sewage treatment tank 1 and the separation tank 22 respectively, and the wall scraping device 23 is installed on the separation tank 22, with the wall scraping end of the wall scraping device 23 located inside the separation tank 22.

[0030] The transmission device 21 includes a transmission pipe 211 and a valve 212.

[0031] The transmission pipe 211 is mounted on the top of the sewage treatment tank 1 via a mounting bracket, with one end of the transmission pipe 211 extending into the sewage treatment tank 1 and the other end connected to the bottom of the separation tank 22. A valve 212 is mounted on the transmission pipe 211.

[0032] The separation tank 22 includes: a tank body 221, a mounting plate 222, a tank cover 223, a limiting rod 224, and a limiting block 225.

[0033] The mounting plate 222 is set on the outer wall of the barrel body 221, and multiple limiting holes are opened on the mounting plate 222. Multiple limiting rods 224 are respectively set at the bottom of the barrel cover 223, and multiple limiting blocks 225 are respectively set at the bottom of the multiple limiting rods 224. The barrel cover 223 is installed on the top of the barrel body 221 through the multiple limiting rods 224 and the multiple limiting holes.

[0034] In another possible embodiment of the present invention, a return pipe (not shown in the figure) is provided at the bottom of the inner side of the tank body 221, and one end of the return pipe passes through the tank body 221, the sewage treatment tank 1 and the isolation layer 11 in sequence and extends thereto facilitate multiple filtration operations.

[0035] It should be noted that a support rod is provided at the bottom of the tank body 221 and extends to the top of the sewage treatment tank 1 to facilitate support of the tank body 221.

[0036] It should be noted that the top of the bucket lid 223 is equipped with a gas outlet pipe 2231 that is connected to its interior, which facilitates the discharge of biogas.

[0037] The wall scraping device 23 includes: a first drive motor 231, a guide rod 232, a semi-circular retaining ring 233, a threaded knob 234, a stirring rod 235, and a scraper 236.

[0038] The first drive motor 231 is mounted on the separation tank 22 via a mounting bracket. The guide rod 232 is rotatably mounted inside the separation tank 22 and has a threaded groove. The top end of the guide rod 232 passes through the separation tank 22 and is connected to the drive end of the first drive motor 231. Multiple semi-circular retaining rings 233, multiple stirring rods 235, and multiple scrapers 236 are sequentially connected and are respectively engaged with the guide rod 232 by multiple semi-circular retaining rings 233. Multiple scrapers 236 are respectively in contact with the inner wall of the separation tank 22. Multiple threaded knobs 234 are respectively threaded onto the threaded groove, and multiple semi-circular retaining rings 233 abut against each pair of threaded knobs 234.

[0039] Preferably, rubber pads (not shown in the figure) are provided on the top and bottom of the multiple semi-circular retaining rings 233 respectively, which effectively increases the friction between the threaded knob 234 and the semi-circular retaining rings 233, thereby preventing them from falling off.

[0040] The auxiliary filter assembly 3 includes: a curved rod 31, a sleeve 32, a connecting rod 33, a filter plate 34, a telescopic rod 35, a first bevel gear 36, a second drive motor 37, and a second bevel gear 38.

[0041] Each separation tank 22 has a curved rod 31 axially mounted on its inner wall, located below each guide rod 232. One end of each curved rod 31 extends outward from the separation tank 22. A sleeve 32 rotates on the curved rod 31. One end of a connecting rod 33 is connected to the sleeve 32, and the other end is hinged to the filter plate 34. The filter plate 34 slides inside the transmission pipe 211. Multiple telescopic rods 35 are respectively mounted on the extended ends of the multiple curved rods 31. Multiple first bevel gears 36 are respectively mounted on the telescopic ends of the multiple telescopic rods 35. A second drive motor 37 is mounted on the top of the sewage treatment tank 1 via a mounting bracket. A second bevel gear 38 is mounted on the drive end of the second drive motor 37 and meshes with the multiple first bevel gears 36.

[0042] It should be noted that the telescopic rod 35 is a damped telescopic rod 35, which prevents it from extending or retracting during operation.

[0043] Specifically, during use, wastewater can be added to the sewage treatment tank 1 through the inlet pipe 13. The wastewater reacts with the sludge bed to produce biogas. The agitation of the biogas forms a sludge with a relatively low concentration. The sludge and water then enter the separation tank 22 through the transmission pipe 211. Then, the first drive motor 231 is turned on, which drives the guide rod 232 to rotate. The guide rod 232 sequentially drives multiple semi-circular retaining rings 233, the stirring rod 235, and the scraper 236 to rotate. In this way, the multiple scrapers 236 can prevent sludge from adhering to the inner wall of the separation tank 22, and the biogas passes through... The air is discharged through the vent pipe 2231, and at the same time the second drive motor 37 is turned on. The second drive motor 37 drives the second bevel gear 38 to rotate, which in turn drives the first bevel gear 36 meshing with it to rotate, which in turn drives the telescopic rod 35 and the curved rod 31 to rotate in sequence, thereby driving the sleeve 32 and the connecting rod 33 to perform circular motion, which in turn drives the filter plate 34 to perform vertical reciprocating motion, so that the filter plate 34 can fully filter the sludge, thereby preventing excessive sludge loss and reducing reaction efficiency. Meanwhile, the wastewater is discharged through the outlet pipe 12 after being filtered through the isolation layer 11.

[0044] It should be noted that when the scraper 236 needs to be disassembled and replaced, by moving one of the telescopic rods 35, the first bevel gear 36 is gradually moved away from the second bevel gear 38. At this time, the corresponding bucket cover 223 is removed. Then, the threaded knob 234 is turned. At this time, the semi-circular retaining ring 233, along with the stirring rod 235 and the scraper 236, can be removed.

[0045] It should be noted that when one of the first bevel gears 36 is not engaged with the second bevel gear 38, the other first bevel gears 36 are engaged with the second bevel gear 38 respectively.

[0046] In summary, the novel UBF anaerobic reactor according to the embodiments of this utility model, on the one hand, facilitates disassembly and replacement by setting a detachable semi-circular retaining ring 233, stirring rod 235 and scraper 236, and on the other hand, with the cooperation of the auxiliary filtration component 3, can perform sewage filtration without stopping the equipment, thereby effectively improving working efficiency, and is simple to operate and highly practical.
