Description

Technical Field

[0001] This utility model relates to the field of water pollution control technology, and in particular to a MABR filtration mechanism for controlling blue-green algae in water pollution. Background Technology

[0002] MABR, or membrane aerated biofilm reactor, is an innovative wastewater treatment technology. Its application in cyanobacterial control and water pollution prevention primarily benefits from its highly efficient biofilm attachment and growth, as well as its membrane filtration capabilities. The MABR filtration system directly supplies oxygen to the biofilm attached to its surface via a hollow fiber membrane. As wastewater flows around the oxygen-permeable membrane, pollutants (including cyanobacteria) enter the biofilm under the influence of concentration gradient and microbial adsorption. Through biological metabolism and proliferation, these pollutants are utilized by microorganisms, assimilated into microbial cells that are fixed on the biofilm, or decomposed into inorganic metabolic products, thereby purifying the water and removing cyanobacteria.

[0003] MABR wastewater treatment plants can effectively filter cyanobacteria in wastewater, but wastewater contains other larger impurities besides cyanobacteria. MABR wastewater treatment plants not only cannot filter these impurities, but are also prone to clogging due to these impurities, affecting their normal operation. Therefore, a MABR filtration mechanism for preventing cyanobacteria in water pollution is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing MABR wastewater treatment systems, which not only cannot filter larger impurities but are also prone to clogging due to these impurities, thus affecting their normal operation. Therefore, this invention proposes a MABR filtration mechanism for preventing blue-green algae in water pollution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A MABR filtration mechanism for controlling blue-green algae in water pollution includes a housing, a first rectangular opening on one side of the housing, a U-shaped plate fixedly connected to one side of the housing, a filtration mechanism inside the housing, a collection mechanism on the U-shaped plate, a water inlet pipe fixedly connected to the top of the housing, and a water outlet pipe fixedly connected to one side of the housing.

[0007] The filtration mechanism includes a first drive motor, a first rotating rod, a second rotating rod, a third rotating rod, a first gear, a second gear, a first pulley, a second pulley, a transmission belt, and a filter screen. The output end of the first drive motor is connected to the first rotating rod. One end of the first rotating rod is fixedly connected to the first gear. One end of the second rotating rod is fixedly connected to the second gear. The second rotating rod is fixedly connected to the first pulley. The third rotating rod is fixedly connected to the second pulley. The transmission belt is sleeved on the first pulley and the second pulley. The first rotating rod and the second rotating rod are fixedly connected to the filter screen.

[0008] Preferably, the box body has a second rectangular opening on both sides, and a rectangular shell is fixedly connected to both sides of the box body. The first rotating rod and the third rotating rod are rotatably connected to the rectangular shell, one end of the second rotating rod is rotatably connected to one side of the box body, and the first drive motor is installed on one side of the rectangular shell.

[0009] Preferably, the collection mechanism includes a second drive motor, a threaded rod, a sliding rod, a moving block, and a collection box. The output end of the second drive motor is connected to the threaded rod, the threaded rod is threadedly connected to the moving block near the second drive motor, the sliding rod is slidably connected to the moving block away from the second drive motor, and the moving block is fixedly connected to both sides of the collection box.

[0010] Preferably, rectangular grooves are provided on both inner walls of the box and the collection box, one end of the sliding rod is fixedly connected to the rectangular groove, the moving block is slidably connected to the rectangular groove, and the second drive motor is installed on one side of the U-shaped plate.

[0011] Preferably, a sliding door is hinged to one side of the collection box, and a handle is fixedly connected to the sliding door. A MABR wastewater treatment unit is installed inside the box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When in use, this equipment filters impurities in wastewater through a filtration mechanism and filter screens. When a large amount of impurities accumulate on the filter screens, the wastewater intake is stopped, and the collection mechanism moves the collection box directly below the filter screens. The filtration mechanism then changes the angle of the two filter screens, causing the impurities on the filter screens to fall off and into the collection box. This prevents impurities from clogging the MABR wastewater processor and ensures its normal operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-4 A MABR filtration mechanism for preventing blue-green algae in water pollution includes a housing 1, a first rectangular opening on one side of the housing 1, a U-shaped plate 2 fixedly connected to one side of the housing 1, a filtration mechanism inside the housing 1, a collection mechanism on the U-shaped plate 2, an inlet pipe fixedly connected to the top of the housing 1, and an outlet pipe 3 fixedly connected to one side of the housing 1.

[0021] Furthermore, the filtration mechanism includes a first drive motor 4, a first rotating rod 5, a second rotating rod 6, a third rotating rod 7, a first gear 8, a second gear 9, a first pulley 10, a second pulley 11, a transmission belt 12, and a filter screen 13. The output end of the first drive motor 4 is connected to the first rotating rod 5. One end of the first rotating rod 5 is fixedly connected to the first gear 8. One end of the second rotating rod 6 is fixedly connected to the second gear 9. The second rotating rod 6 is fixedly connected to the first pulley 10. The third rotating rod 7 is fixedly connected to the second pulley 11. The transmission belt 12 is sleeved on the first pulley 10 and the second pulley 11. The first rotating rod 5 and the second rotating rod 6 are fixedly connected to the filter screen 13.

[0022] The system provides power to the first drive motor 4 via an external device and controls its opening and closing. The first drive motor 4 drives the first rotating rod 5 to rotate, which in turn drives the first gear 8 to rotate. The first gear 8 drives the second gear 9 to rotate, which in turn drives the second rotating rod 6 to rotate. The second rotating rod 6 drives the first pulley 10 to rotate, which in turn drives the second pulley 11 to rotate via the transmission belt 12. The second pulley 11 drives the third rotating rod 7 to rotate. When a lot of impurities accumulate on the filter screen 13, the first rotating rod 5 and the third rotating rod 7, which rotate in opposite directions, drive the filter screen 13 to rotate, changing the angle between the two filter screens 13. As a result, the impurities on the filter screen 13 fall off the two filter screens 13.

[0023] Furthermore, a second rectangular opening is provided on both sides of the box body 1, and a rectangular shell 14 is fixedly connected to both sides of the box body 1. The first rotating rod 5 and the third rotating rod 7 are rotatably connected to the rectangular shell 14, one end of the second rotating rod 6 is rotatably connected to one side of the box body 1, and the first drive motor 4 is installed on one side of the rectangular shell 14.

[0024] The function of the second rotating rod 6 is to make the first rotating rod 5 and the third rotating rod 7 rotate in opposite directions through two gears and two pulleys, so as to smoothly control the two filter screens 13 to rotate upward or downward simultaneously on the side that is close to each other.

[0025] Furthermore, the collection mechanism includes a second drive motor 15, a threaded rod 16, a sliding rod 17, a moving block, and a collection box 18. The output end of the second drive motor 15 is connected to the threaded rod 16. The threaded rod 16 is threadedly connected to the moving block near the second drive motor 15. The sliding rod 17 is slidably connected to the moving block away from the second drive motor 15. The moving block is fixedly connected to both sides of the collection box 18.

[0026] Rectangular grooves are provided on both inner walls of the box 1 and the collection box 18. One end of the sliding rod 17 is fixedly connected to the rectangular groove, and the moving block is slidably connected to the rectangular groove. The second drive motor 15 is installed on one side of the U-shaped plate 2.

[0027] The sliding rod 17 allows the side of the collection box 18 away from the second drive motor 15 to move smoothly together;

[0028] The second drive motor 15 is powered by an external device and its opening and closing are controlled. When a lot of impurities accumulate on the filter screen 13, the second drive motor 15 drives the threaded rod 16 to rotate. The threaded rod 16 drives the moving block to move along the rectangular groove. The moving block drives the collection box 18 to move through the first rectangular opening into the box 1 until the collection box 18 is directly below the filter screen 13. The filter screen 13 then rotates downwards, causing the impurities to fall into the collection box 18.

[0029] Meanwhile, the specific model and specifications of the first drive motor 4 and the second drive motor 15 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0030] Furthermore, a sliding door 19 is hinged to one side of the collection box 18, and a handle is fixedly connected to the sliding door 19. A MABR wastewater treatment unit 20 is installed inside the box 1.

[0031] After the impurities on the filter screen 13 are collected in the collection box 18, the filter screen 13 is moved to the outside of the box 1. The sliding door 19 is opened by the handle so that the sliding door 19 is parallel to the inner bottom surface of the collection box 18, which makes it convenient to take out the impurities in the collection box 18 for cleaning.

[0032] The wastewater, after filtering out impurities, passes through two MABR wastewater processors 20, where the blue-green algae in the wastewater are filtered twice, and finally discharged through the outlet pipe 3.

[0033] The working principle of this utility model:

[0034] First, wastewater enters the device through the inlet pipe. The filter screen 13 filters the impurities in the wastewater. The filtered wastewater passes through two MABR wastewater processors 20, which filter the blue-green algae in the wastewater twice. Finally, it is discharged through the outlet pipe 3.

[0035] Subsequently, when a lot of impurities accumulate on the filter screen 13, the entry of sewage is stopped. The second drive motor 15 drives the threaded rod 16 to rotate. The threaded rod 16 drives the moving block to move along the rectangular groove. The moving block drives the collection box 18 to move through the first rectangular opening into the box 1 until the collection box 18 is located directly below the filter screen 13.

[0036] The first drive motor 4 drives the first rotating rod 5 to rotate, the first rotating rod 5 drives the first gear 8 to rotate, the first gear 8 drives the second gear 9 to rotate, the second gear 9 drives the second rotating rod 6 to rotate, the second rotating rod 6 drives the first pulley 10 to rotate, the first pulley 10 drives the second pulley 11 to rotate through the transmission belt 12, the second pulley 11 drives the third rotating rod 7 to rotate, so that the angle of the two filter screens 13 changes, and the impurities on the filter screens 13 fall off the two filter screens 13 and fall into the collection box 18;

[0037] Finally, the collection box 18 is moved onto the U-shaped plate 2, and the sliding door 19 is opened by the handle to remove the impurities in the collection box 18 for cleaning.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
