DETAILED DESCRIPTION

[0032] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] The embodiment of the present invention provides a filler interception grid device with aeration, flushing and phosphorus removal functions, such as Figure 1-14 As shown, the filler intercepting grid device with aeration, flushing and phosphorus removal function includes: a partition wall 1 and a grid 2 installed in the partition wall 1 for intercepting fillers; a bracket 3 arranged on the drainage side of the grid 2; an aeration pipe 4 installed on the bracket 3 for aeration and flushing the grid 2; a U-shaped frame 5 arranged on the water inlet side of the grid 2, and a cleaning brush 6 rotatably installed in the U-shaped frame 5 for cleaning the fillers adhered to the surface of the grid 2; and a moving mechanism arranged on the partition wall 1 for driving the U-shaped frame 5 to move.

[0034] In this embodiment, when sewage flows through the grid 2, the grid 2 intercepts the filler therein, and the aeration pipe 4 is connected to the air pump, and the discharged gas flushes the grid 2, so that the filler adhering to the water inlet side of the grid 2 is pushed away from the grid 2 by the airflow, which helps to prevent the filler from accumulating and clogging. After aeration and flushing, the filler is loosened, and then the filler is sucked out of the sewage pool by the suction device, further reducing the accumulation of filler on the grid 2. When it is necessary to clean the water inlet side of the grid 2 more deeply, the moving mechanism is started, and the mechanism drives the U-shaped frame 5 to move smoothly. At the same time, the cleaning brush 6 installed in the U-shaped frame 5 rotates at a high speed to comprehensively and efficiently clean the filler adhering to the surface of the grid 2.

[0035] Through the dual functions of aeration flushing and the cleaning brush 6, the accumulation of fillers on the grille 2 is effectively reduced, the drainage of the grille 2 is ensured to be smooth, and the operating efficiency of the grille 2 is improved. Through the automatic operation of the moving mechanism and the cleaning brush 6, the reliance on manual cleaning is reduced and the degree of automation of the equipment is improved. Aeration flushing can not only remove debris on the grille 2, but also promote the renewal of the biofilm on the surface of the grille 2. The microorganisms on the biofilm play an important role in the phosphorus removal process, and their renewal helps to maintain and improve the phosphorus removal efficiency.

[0036] In a further preferred embodiment of the present invention, the moving mechanism includes: a support frame 7 fixedly mounted on the top of the partition wall 1; a group of sliding openings are opened on the top of the partition wall 1; a group of one-way screws 8 are rotatably mounted on the support frame 7, a group of the one-way screws 8 are threadedly sleeved with sliders 9, and a group of the sliders 9 respectively pass through a group of the sliding openings, and any one of the sliders 9 is fixedly connected to the U-shaped frame 5; a motor 10 fixedly mounted on the top of the partition wall 1 for driving the one-way screw 8 to rotate, and the output shaft of the motor 10 is fixedly connected to any one of the one-way screws 8; a gear transmission mechanism is arranged on the U-shaped frame 5 and the partition wall 1 for driving the cleaning brush 6 to rotate.

[0037] In this embodiment, the motor 10 drives the one-way screw 8 to rotate, so that the slider 9 drives the U-shaped frame 5 to reciprocate along the slide. While the U-shaped frame 5 moves, the gear transmission mechanism operates synchronously, so that the cleaning brush 6 rotates in the U-shaped frame 5 to clean the water inlet side of the grille 2. At the same time, the aeration pipe 4 continues to aerate and flush the grille 2 to further loosen and remove the filler. The combination of the one-way screw 8 and the slider 9 driven by the motor 10 realizes the smooth reciprocating movement of the U-shaped frame 5. Combined with the rotation of the cleaning brush 6 driven by the gear transmission mechanism, the water inlet side of the grille 2 is comprehensively and efficiently cleaned.

[0038] In a further preferred embodiment of the present invention, the gear transmission mechanism includes: a connecting cover 11 fixedly installed in the U-shaped frame 5, and the connecting cover 11 is rotatably connected to the rotating shaft of the cleaning brush 6; a rack 12 fixedly installed on the top of the mounting opening of the partition wall 1; a driven gear 13 rotatably installed on one side of the connecting cover 11, and the driven gear 13 and the rack 12 are meshed with each other; a group of differential gears 14 are respectively arranged on the rotating shaft of the cleaning brush 6 and in the connecting cover 11, and a group of the differential gears 14 are meshed with each other; a group of bevel gears 15 are fixedly sleeved on the rotating shaft of the driven gear 13 and the rotating shaft of the differential gear 14 away from the cleaning brush 6, and a group of bevel gears 15 are meshed with each other.

[0039] In this embodiment, when the motor 10 drives the one-way screw 8 to rotate and drives the slider 9 and the U-shaped frame 5 to move along the slide, the driven gear 13 rolls and rotates along the rack 12, and the rotational force of the driven gear 13 is transmitted to the differential gear 14 away from the cleaning brush 6 through a group of bevel gears 15. The differential gear 14 utilizes the differential characteristics of the gears to transmit the rotational force to the rotating shaft of the cleaning brush 6 and make it rotate at high speed. Through the design of the gear transmission mechanism, the high-speed rotation of the cleaning brush 6 is achieved, and the cleaning efficiency is improved. The introduction of the differential gear set allows the rotation speed of the cleaning brush 6 to be adjusted independently of the moving speed of the U-shaped frame 5, thereby optimizing the cleaning effect.

[0040] In a further preferred embodiment of the present invention, a partition net 16 for protecting the rack 12 is fixedly installed on the top of the installation opening, and the partition net 16 is located on one side of the rack 12 and the driven gear 13.

[0041] In this embodiment, the introduction of the partition net 16 effectively prevents direct contact between the filler and the rack 12, reduces the risk of malfunction of the gear transmission mechanism due to interference from impurities, and ensures the stable operation of the equipment. Through the protection of the partition net, the working environment of the gear transmission mechanism is significantly improved, and the reliability and durability of the equipment are further improved. Due to the protective effect of the partition net 16, the situation in which the gear transmission mechanism needs frequent maintenance due to interference from impurities is effectively alleviated, thereby reducing maintenance costs.

[0042] In a further preferred embodiment of the present invention, an L-shaped block 17 is fixedly installed on the right side of the partition wall 1 , a connecting spring 18 is fixedly installed on the L-shaped block 17 , and one end of the connecting spring 18 is fixedly connected to the bracket 3 .

[0043] In this embodiment, when the bracket 3 is subjected to external force (the roller 56 moves left and right, thereby pushing the bracket 3 to move backward), it can be buffered and adjusted to a certain extent through the elasticity of the connecting spring 18, thereby maintaining the stability and position accuracy of the bracket 3 and the aeration pipe 4 it carries.

[0044] In a further preferred embodiment of the present invention, a connecting plate 30 is fixedly installed on the top of the grille 2, and the connecting plate 30 passes through the top of the support frame 7 and the partition wall 1. The connecting plate 30 is fixed to the support frame 7 by bolts, and a hanging ring 31 is fixedly installed on the top of the connecting plate 30.

[0045] In this embodiment, when the grille 2 needs to be replaced, the operator can first loosen and remove the bolts between the connecting plate 30 and the support frame 7 to release the fixing of the grille 2, and then use the hook of the lifting equipment (such as a crane or a hoist) to hang on the hanging ring 31, and lift the grille 2 and the attached connecting plate 30 together through the lifting force of the lifting equipment. In this way, the operator can replace or repair the grille 2 under safe and convenient conditions. The design of the connecting plate 30 and the hanging ring 31 greatly simplifies the replacement process of the grille 2, reduces the difficulty of operation and time cost. The operator does not need to perform complicated disassembly work, but only needs to simply loosen the bolts and use the lifting equipment to complete the replacement of the grille 2, thereby improving work efficiency.

[0046] In a further preferred embodiment of the present invention, a group of limiting mechanisms for assisting the installation of the grille 2 is provided at the top of the support frame 7, and the limiting mechanisms include: a connecting block 19 provided on the top of the support frame 7; a sliding rod 20 slidably installed on the connecting block 19; a limiting block 21 fixedly installed at one end of the sliding rod 20 for limiting the grille 2; a reset spring 22 mounted on the sliding rod 20 for resetting the limiting block 21; and a driving mechanism provided on the partition wall 1 and the connecting plate 30 for driving the connecting block 30 to move.

[0047] In this embodiment, when the connecting plate 30 is away from the support frame 7, a group of limit blocks 21 contact and clamp both sides of the grille 2, thereby limiting its position. When removing the old grille 2 and installing the new grille 2, it is only necessary to place the new grille 2 between the two limit blocks 21 so that the two limit blocks 21 limit its position and ensure that it is aligned with the through opening on the support frame 7. Then, the operator can easily fix the grille 2 to the support frame 7 through the connecting plate 30 and bolts. Through the limiting effect of the limiting mechanism, the operator can more easily place the grille 2 in the correct position without complicated alignment and adjustment work, thereby simplifying the installation process.

[0048] In a further preferred embodiment of the present invention, the driving mechanism includes: a connection box 23 fixedly mounted on the top of the mounting port; a threaded rod 24 rotatably mounted in the connection box 23; a threaded barrel 25 threadedly sleeved on the threaded rod 24, a Z-shaped block 26 fixedly mounted on the top of the threaded barrel 25, the Z-shaped block 26 passes through the top of the support frame 7 and is fixedly connected to the connecting block 19; a driven gear 27 rotatably mounted on one side of the connection box 23; a rack 28 fixedly mounted in the groove of the connecting plate 30, the rack 28 meshing with the driven gear 27; a bevel gear 29 fixedly sleeved on the rotating shafts of the threaded rod 24 and the driven gear 27, respectively, and the two bevel gears 29 meshing with each other.

[0049] In this embodiment, when the connecting plate 30 moves upward, it will drive the rack 28 to move synchronously, and then drive the driven gear 27 to rotate. When the driven gear 27 rotates, its rotational force will be transmitted to the threaded rod 24 through the bevel gear 29, causing the threaded rod 24 to rotate. The rotation of the threaded rod 24 will drive the threaded cylinder 25 to move left and right in the horizontal direction, and then drive the connecting block 19 and the limit block 21 to move synchronously through the Z-shaped block 26. When the connecting plate 30 is away from the support frame 7, the limit block 21 will contact and clamp the two sides of the grille 2 to achieve the limiting effect on the grille 2. Through the design of the driving mechanism, the automatic limiting function of the grille 2 during the installation process is realized. The operator does not need to manually adjust the position of the limit block 21, but only needs to place the grille 2 in the correct position and fix the connecting plate 30.

[0050] In a further preferred embodiment of the present invention, the limit block 21 is composed of a vertical portion and an arc portion, the arc portion is located at the top of the vertical portion, and the threaded barrel 25 is arranged in a rectangular shape.

[0051] In this embodiment, by setting the arc portion, the grille 2 can be inserted between the two limit blocks 21 more smoothly, reducing the friction and resistance during the installation process and improving the convenience of installation. The rectangular threaded barrel 25 can more effectively resist torsion and displacement, ensuring the accuracy and stability of the limit block 21 during the movement, and improving the reliability and safety of the entire device.

[0052] In a further preferred embodiment of the present invention, baffles 54 are installed on both sides of the U-shaped frame 5, and a plurality of connecting pipes 50 for removing fillers are installed on one side of the U-shaped frame 5.

[0053] In this embodiment, the presence of the baffle 54 effectively prevents the filler from scattering during the cleaning process, ensuring the neatness and efficiency of the cleaning work. The U-shaped frame 5 is connected to the water pump through the connecting pipe 50, so that the filler can be quickly and thoroughly cleaned. By using the connecting pipe 50 in conjunction with the water pump, the filler on the U-shaped frame 5 and the grille 2 can be quickly sucked out, greatly improving the cleaning efficiency. Through the strong suction force of the water pump, it can be ensured that the filler on the U-shaped frame 5 and the grille 2 is thoroughly cleaned, avoiding the problem of residue.

[0054] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0055] In another embodiment of the present invention, a mounting plate 32 is fixedly mounted on the U-shaped frame 5 and the other slider 9, and a surface detection mechanism 33 for detecting protrusions on the surface of the grille 2 is provided on both mounting plates 32, and a driving sprocket 39 is fixedly sleeved on one group of the one-way screws 8, and a chain 40 is sleeved on one group of the driving sprockets 39.

[0056] In this embodiment, when the one-way screw 8 rotates, it will drive the active sprocket 39 thereon to rotate synchronously. Since a group of active sprockets 39 are connected by a chain 40, when one active sprocket 39 rotates, it will drive other active sprockets 39 to rotate synchronously through chain transmission. In this way, a group of one-way screws 8 can achieve synchronous operation. At the same time, since the cleaning brush 6 and the surface detection mechanism 33 are respectively mounted on the slider 9 and the mounting plate 32, and the movement of the slider 9 is driven by the one-way screw 8, when a group of one-way screws 8 operate synchronously, the cleaning brush 6 and the surface detection mechanism 33 will also move synchronously. This design ensures that while the cleaning brush 6 is cleaning the surface of the grille 2, the surface detection mechanism 33 can detect the protrusions on the surface of the grille 2 in real time.

[0057] In another embodiment of the present invention, the surface detection mechanism 33 includes: a mounting box 34 fixedly mounted on one side of the mounting plate 32; a detection wheel 35 slidably mounted on one side of the mounting box 34, the detection wheel 35 being in contact with the surface of the grille 2; a fixing plate 36 fixedly mounted on a connecting rod of the detection wheel 35, the fixing plate 36 being located in the mounting box 34, and a compression spring 37 being sleeved on the connecting rod, the two ends of the compression spring 37 being fixedly connected to the fixing plate 36 and one side of the inner wall of the mounting box 34, respectively; and a displacement sensor 38 fixedly mounted on one side of the fixing plate 36 for detecting surface defects of the grille 2.

[0058] In this embodiment, when the detection wheel 35 moves on the surface of the grille 2, if fillers adhere to the surface of the grille 2 and the cleaning brush 6 cannot clean it out, the surface of the grille 2 will be uneven. At this time, the detection wheel 35 will be affected by the uneven surface and displaced, thereby driving the fixing plate 36 and the displacement sensor 38 to move together. The displacement sensor 38 can detect this displacement change in real time and transmit the signal to the control system, thereby realizing accurate detection of surface defects of the grille 2. Through the setting of the compression spring 37, the detection wheel 35 can always move close to the grille 2, even if there is an uneven surface of the grille 2, it can still be accurately detected. The displacement change of the detection wheel 35 can be detected in real time through the displacement sensor 38, and the signal is transmitted to the control system, thereby realizing accurate detection of surface defects of the grille 2.

[0059] In another embodiment of the present invention, a flow rate monitoring mechanism for monitoring the flow rate of water on the drainage side of the grille 2 is fixedly installed on one side of the partition wall 1, and the flow rate monitoring mechanism includes: a fixing box 41 fixedly installed on one side of the partition wall 1; a support rod 42 rotatably installed on the fixing box 41; a fixing piece 43 provided at one end of the support rod 42; a flow meter probe rod 44 installed on the fixing piece 43 for monitoring the flow rate; and a linkage mechanism provided on the fixing box 41 and the one-way screw 8 for synchronously driving the one-way screw 8 and the support rod 42 to rotate.

[0060] In this embodiment, when the U-shaped frame 5 moves toward the surface of the grille 2 (achieved by the drive of the one-way screw 8), the linkage mechanism will synchronously drive the support rod 42 to rotate, so that the support rod 42 will drive the fixing part 43 and the flow meter probe rod 44 to rotate together, until the flow meter probe rod 44 extends into the sewage pool, and the water flow velocity at the drainage end of the grille 2 is monitored in real time. The real-time monitoring of the water flow velocity at the drainage end of the grille 2 by the flow meter probe rod 44 can accurately obtain water flow information, providing a strong basis for the subsequent cleaning or replacement of the grille 2. Through the introduction of the flow velocity monitoring mechanism, the grille device not only has a cleaning function, but also has the function of real-time monitoring of the water flow velocity, thereby enhancing the practicability and functionality of the equipment.

[0061] In another embodiment of the present invention, the fixing member 43 is composed of a U-shaped block 431, a pull rod 432, a group of arc blocks 433 and a connecting spring 434. The U-shaped block 431 is fixedly installed on the support rod 42, the pull rod 432 is slidably arranged on the U-shaped block 431, a group of arc blocks 433 are respectively installed in the pull rod 432 and the U-shaped block 431 for fixing the flow meter probe 44 in the U-shaped block 431, and the connecting spring 434 is sleeved on the pull rod 432, and the two ends of the connecting spring 434 are respectively in contact with the U-shaped block 431 and the arc block 433.

[0062] In this embodiment, when the pull rod 432 is pulled, the two arc blocks 433 move away from each other, and then the flow meter probe rod 44 can be removed. Through the coordinated use of the arc block 433 and the connecting spring 434, the flow meter probe rod 44 can be firmly clamped, avoiding the loosening or falling off caused by water flow impact during the monitoring process. The adjustable design of the fixing part 43 makes it possible to adapt to flow meter probe rods 44 of different diameters, thereby improving the applicability and flexibility of the equipment.

[0063] In another embodiment of the present invention, the linkage mechanism includes: a group of differential gears 45 respectively installed on the rotating shafts of the fixed box 41 and the support rod 42, a group of differential gears 45 are meshed with each other, and two differential sprockets 46 are respectively fixedly mounted on the one-way screw 8 and the rotating shafts of the differential gears 45 located on the fixed box 41; and a chain 47 mounted on the two differential sprockets 46.

[0064] In this embodiment, when the one-way screw 8 starts to rotate under the action of the driving mechanism, its rotational force is first transmitted to the differential sprocket 46 fixedly connected thereto, and then, through the transmission of the chain 2 47, this rotational force is transmitted to the differential sprocket 46 located on the fixed box 41, thereby driving the differential gear 2 45 connected thereto to rotate. Since the differential gear 2 45 and the gears on the rotating shaft of the support rod 42 are meshed with each other, the support rod 42 will also rotate accordingly.

[0065] When the one-way screw 8 drives the slider 9 to slide to the extreme position, due to the differential effect of the gears, the rotation angle of the support rod 42 will be limited to between 90 and 115 degrees. This design not only ensures that the flow meter probe 44 can be smoothly extended into the sewage pool for monitoring, but also avoids the problem of damage to the mechanism or inaccurate monitoring caused by excessive rotation. Through the design of the linkage mechanism, the synchronous rotation drive between the one-way screw 8 and the support rod 42 is ensured, so that the flow meter probe 44 can be synchronously extended into the sewage pool for monitoring as the U-shaped frame 5 moves.

[0066] In another embodiment of the present invention, a filtering mechanism for filtering fillers is installed on one side of the partition wall 1, and the filtering mechanism includes: a filter box 48 fixedly installed on the left side of the partition wall 1, and the filter box 48 is fixedly connected to the connecting pipe 50; a filter cartridge 49 for filtering fillers is arranged in the filter box 48; and an inclined plate 51 fixedly installed on the top of the filter cartridge 49 for guiding sewage, and the inclined plate 51 is located below the pipe mouth of the connecting pipe 50.

[0067] In this embodiment, when the water pump sucks out sewage through the connecting pipe 50, the sewage first enters the filter cartridge 49 in the filter box 48 for filtering. The design of the inclined plate 51 allows the sewage entering the filter box 48 to be guided to the filter cartridge 49 along its surface, thereby ensuring that the sewage can fully contact the filter cartridge 49 and be effectively filtered. The filtered sewage is discharged into the next-level sewage pool. By introducing the filtering mechanism and the filtering function of the filter cartridge 49, the filtering effect in the sewage treatment process can be significantly improved. The design of the inclined plate 51 optimizes the flow direction of the sewage, so that the sewage can fully contact the filter filler and be effectively filtered, thereby improving the filtering efficiency.

[0068] In another embodiment of the present invention, a limit plate 52 is fixedly installed in the filter box 48 , a magnet bar 53 is fixedly installed on the top of the limit plate 52 , and the magnet bar 53 is adsorbed to the filter cartridge 49 .

[0069] In this embodiment, when the filter cartridge 49 needs to be installed in the filter box 48, the filter cartridge 49 only needs to be moved close to the magnet bar 53, and the filter cartridge 49 can be easily positioned on the limit plate 52 by utilizing the adsorption force of the magnet, without the need for additional fixing devices or operating steps. Similarly, when the filter cartridge 49 needs to be removed or replaced, the filter cartridge 49 can be easily removed from the filter box 48 by simply overcoming the adsorption force of the magnet.

[0070] In another embodiment of the present invention, a connecting plate 55 is fixedly installed on one side of the bracket 3, and the connecting plate 55 consists of multiple flat parts and two inclined parts. The two inclined parts are respectively located between the multiple flat parts. A roller 56 is fixedly installed on one side of the mounting plate 32.

[0071] In this embodiment, when the one-way screw 8 starts to drive the mounting plate 32 to move, the roller 56 will roll along the connecting plate 55. During the rolling process of the roller 56, when it contacts the inclined portion of the connecting plate 55, due to the guiding effect of the inclined portion, the connecting plate 55 will move to the rear side (the "rear side" here is relative to the moving direction of the mounting plate 32). At the same time, the connecting spring 18 will be deformed. This deformation is caused by the movement of the connecting plate 55, which plays a buffering and regulating role. This design ensures that when the roller 56 rolls on the connecting plate 55, especially when it contacts the inclined portion, it can transition smoothly without sudden impact or jamming. Through the special design of the connecting plate 55 and the rolling of the roller 56, as well as the deformation of the connecting spring 18, it can be ensured that the mounting plate 32 will not directly collide with the aeration pipe 4 during the movement, which protects the aeration pipe 4 and prevents it from being damaged by collision.

[0072] In summary, compared with the related art, the device effectively solves the problem of packing accumulation and blockage during the operation of the existing grille device through the coordinated use of aeration flushing, U-shaped frame and cleaning brush.
