[0031] The following will be combined with the 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.

[0032] Reference Figure 1 - Figure 5 The utility model provides an embodiment: an anaerobic device for a biological pool in a sewage treatment plant, comprising a box body 1 and a stirring rod 4. A support plate 27 is fixedly connected to the bottom of the box body 1. Both ends of the stirring rod 4 are fixedly connected to square rods 5. A connecting shaft 6 is provided at one end of the square rod 5 away from the stirring rod 4. An inclined plate 9 is fixedly connected to the top of the outer side of the stirring rod 4. A connecting plate 8 is fixedly connected to the top wall of the box body 1. Two round blocks 7 are fixedly connected to one side of the connecting plate 8. The outer edge of the inclined plate 9 is set between the two round blocks 7. A motor 10 is fixedly connected to the middle side of the top of the box body 1. The output end of the motor 10 is fixedly connected to the inside of the upper connecting shaft 6. The right side of the box body 1 A water inlet pipe 13 is fixedly connected to the upper side, a sewage pump 15 is provided on the outside of the water inlet pipe 13, a water outlet pipe 14 is fixedly connected to the lower right side of the box body 1, an air outlet pipe 16 is fixedly connected to the left top of the box body 1, one end of the air outlet pipe 16 is fixedly connected to a purification box 17, an activated carbon filter 18 is slidingly connected to the inside of the purification box 17, a fan 19 is fixedly connected to the bottom of the purification box 17, a base 3 is fixedly connected to the bottom of the purification box 17, an air outlet pipe 2 20 is fixedly connected to one side of the fan 19, and two fixed components are fixedly connected to the outside of the purification box 17, and the fixed components are used for installing and disassembling the activated carbon filter 18.

[0033] Specifically, after starting the sewage pump 15, the sewage will flow into the box body 1 along the water inlet pipe 13. Subsequently, the motor 10 is turned on, and its power is transmitted to the connecting shaft 6, causing the square rod 5 and the stirring rod 4 to operate accordingly. Under the action of the two round blocks 7, the inclined plate 9 installed on the stirring rod 4 enables the stirring rod 4 and the square rod 5 to move up and down while rotating, which can increase the contact area between the sewage and the anaerobic bacteria, ensure the uniformity of the sewage during the reaction process, reduce precipitation, thereby accelerating the reaction process, and improving the reaction efficiency and thoroughness. After the reaction is completed, the system will start the fan 19, and use the outlet pipe 16 to introduce the generated gas into the purification box 17, filter it through the activated carbon filter 18, and the filtered gas is discharged through the outlet pipe 2 20.

[0034] Reference Figure 4 and Figure 5 The fixed component includes a thin shell 23, one side of the thin shell 23 is fixedly connected to one side of the purification box 17, the top of the thin shell 23 is fixedly connected to the thin shell 1 22, the inside of the thin shell 23 is slidably connected to the plug rod 21, the outside of the plug rod 21 is fixedly connected to the baffle 25, the other side of the outside of the plug rod 21 is provided with a spring 26, and the top of the baffle 25 is provided with a blocking block 24.

[0035] Specifically, when performing the disassembly operation of the activated carbon filter 18, the plug-in rod 21 is pulled, and this action causes the baffle 25 to move outward. At the same time, the spring 26 will be compressed due to the movement of the baffle 25. With the help of this mechanism, the blocking block 24 will slide from the inside of the thin shell 1 22 into the thin shell 2 23. The key to this design is that it prevents the plug-in rod 21 from automatically resetting and reinserting the activated carbon filter 18 under the elastic force of the spring 26 after disassembly. To install the filter, just lift the blocking block 24, and under the push of the spring 26, the baffle 25 and the plug-in rod 21 will automatically return to their original position and be firmly embedded between the purification box 17 and the filter activated carbon filter 18, thereby completing the installation of the filter.

[0036] Reference Figure 1 - Figure 5 , a reagent port 11 is fixedly connected to the right side of the top of the box body 1, and a plurality of support columns 2 are fixedly connected around the bottom of the box body 1, one of the connecting shafts 6 is rotatably connected to the upper side of the inside of the box body 1, and the bottom of the other connecting shaft 6 is rotatably connected to the inside of the support plate 27, and a sewage outlet 12 is fixedly connected to the bottom of the box body 1, the upper side of the blocking block 24 is slidably connected to the inside of the thin shell 1 22, and the lower side of the blocking block 24 is slidably connected to the inside of the thin shell 23, one end of the spring 26 is fixedly connected to the middle of the baffle 25, and the other end of the spring 26 is fixedly connected to the inner wall of the thin shell 23, the plug-in rod 21 passes through the purification box 17 and is inserted into the inside of the activated carbon filter 18, one side of the thin shell 1 22 is fixedly connected to the outside of the purification box 17, and the outside of the baffle 25 is slidably connected to the inside of the thin shell 23.

[0037] Specifically, a reagent port 11 is provided on the right side of the top of the box body 1 for anaerobic bacteria and reagents. A plurality of support columns 2 are fixed around the bottom of the box body 1 to provide a stable foundation. There are two connecting shafts 6, one is located on the upper side of the interior of the box body 1 and drives the connecting parts to rotate, and the other is fixed under the support plate 27. A sewage outlet 12 is provided at the bottom to facilitate cleaning of internal dirt. The blocking block 24 is cleverly designed, with the upper part embedded in the thin shell 1 22 and the lower part sliding in the thin shell 2 23 to ensure smooth installation and disassembly of the filter. One end of the spring 26 is fixed to the center of the baffle 25, and the other end is fixed to the inner wall of the thin shell 23, which plays a role in buffering and maintaining balance. The plug-in rod 21 runs through the entire purification box 17 and is tightly connected to the activated carbon filter 18 to ensure the stability of gas filtration. The thin shell 1 22 is fixed to one side of the purification box 17, providing a stable working platform. The baffle 25 is designed to be slidable to facilitate the operation of the filter.

[0038] Working principle: open the valve outside the reagent port 11, add anaerobic bacteria, turn on the sewage pump 15 switch, the sewage enters the box 1 through the water inlet pipe 13, turn on the switch of the motor 10, the output end of the motor 10 drives the connecting shaft 6 to rotate, and then the square rod 5 and the stirring rod 4 rotate, the inclined plate 9 on the stirring rod 4 is in an inclined state, and because the inclined plate 9 is between the two round blocks 7, it drives the stirring rod 4 and the square rod 5 to move up and down while rotating, increasing the contact area between the sewage and the anaerobic bacteria, making the sewage more uniform during the reaction, and not easy to produce excessive precipitation, which is conducive to accelerating the reaction, making the reaction effect better and the reaction more complete. After the reaction is completed, the fan 19 is driven to pass the generated gas through the outlet pipe 16 into the activated carbon of the purification box 17. The filter 18 filters and the air is discharged through the air outlet pipe 20 after the filtration is completed. When the activated carbon filter 18 needs to be removed, the plug-in rod 21 is pulled. This action will drive the baffle 25 to move outward. At the same time, the spring 26 will be compressed, and the blocking block 24 will slide from the inside of the thin shell 1 22 into the thin shell 2 23. This design prevents the plug-in rod 21 from re-entering the activated carbon filter 18 under the elastic force of the spring 26 after the hand is released. At this time, the activated carbon filter 18 is taken away. When the activated carbon filter 18 needs to be installed, only the blocking block 24 needs to be pulled upward. At this time, under the elastic force of the spring 26, the baffle 25 and the plug-in rod 21 will move inward until they are firmly inserted into the purification box 17 and plugged into the inside of the activated carbon filter 18. At this time, the installation is completed.
