DETAILED DESCRIPTION

[0032] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all directed to the same embodiment, or to a common embodiment. It is expressly understood that any of the embodiments described herein can be incorporated into any other embodiment.

[0033] The embodiment of the present application provides a filler interception grid device with aeration flushing dephosphorization function, as shown inFigures 1-14 As shown, the filler interception grid device with aeration flushing dephosphorization function comprises a partition wall 1, a grid 2 installed in the partition wall 1 for intercepting fillers, a support 3 arranged on the water drainage side of the grid 2, an aeration pipe 4 installed on the support 3 for aeration flushing treatment of the grid 2, a U-shaped frame 5 arranged on the water inlet side of the grid 2, a cleaning brush 6 rotatably installed in the U-shaped frame 5 for cleaning 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 the embodiment, when sewage flows through the grid 2, the grid 2 intercepts fillers therein, the aeration pipe 4 is connected with a gas pump and flushes the grid 2 through discharged gas, so that fillers adhered to the water inlet side of the grid 2 are pushed away from the grid 2 by the gas flow, which helps to prevent the fillers from accumulating and blocking. After aeration flushing, the fillers are loosened, and then the fillers are sucked out of the sewage pool through a suction device, further reducing the accumulation of fillers 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, which drives the U-shaped frame 5 to move stably, and at the same time, the cleaning brush 6 installed in the U-shaped frame 5 rotates at high speed, so that the fillers adhered to the surface of the grid 2 are cleaned comprehensively and efficiently.

Through the automatic operation of the moving mechanism and the cleaning brush 6, the dependence on manual cleaning is reduced, and the automation degree of the equipment is improved. Aeration flushing not only can remove sundries on the grid 2, but also can promote the renewal of the biofilm on the surface of the grid 2.

[0039] In the embodiment, when the motor 10 drives the unidirectional screw 8 to rotate and drives the slider 9 and the U-shaped frame 5 to move along the sliding channel, the driven gear one 13 rolls and rotates along the rack one 12, the rotating force of the driven gear one 13 is transmitted to the differential gear one 14 away from the cleaning brush 6 through the group of bevel gears one 15, the differential gear one 14 utilizes the differential characteristics of the gear to transmit the rotating force to the rotating shaft of the cleaning brush 6 and makes it rotate at high speed, through the design of the gear transmission mechanism, the high-speed rotation of the cleaning brush 6 is realized, the cleaning efficiency is improved, and the introduction of the differential gear set makes the rotating speed of the cleaning brush 6 adjustable independently of the moving speed of the U-shaped frame 5, so that the cleaning effect is optimized.

[0045] In the embodiment, when the grid 2 needs to be replaced, the operator can first loosen and remove the bolts between the connecting plate 30 and the support frame 7, release the fixation of the grid 2, then use the hook of the hoisting equipment (such as a crane or a hoist) to hang on the hanging ring 31, and lift the grid 2 and the connecting plate 30 together by the lifting force of the hoisting equipment, so that the operator can replace or maintain the grid 2 in a safe and convenient condition, and the replacement process of the grid 2 is greatly simplified by the design of the connecting plate 30 and the hanging ring 31, and the operation difficulty and time cost are reduced. The operator does not need to perform complex disassembly work, but only needs to simply loosen the bolts and use the hoisting equipment to complete the replacement of the grid 2, thereby improving the work efficiency.

[0046] In the further preferred embodiment of the present application, the top of the support frame 7 is provided with a set of limiting mechanisms for assisting the installation of the grid 2, the limiting mechanisms comprise: a connecting block 19 arranged at the top of the support frame 7; a sliding rod 20 slidingly installed on the connecting block 19; a limiting block 21 fixedly installed on one end of the sliding rod 20 for limiting the grid 2; a reset spring 22 sleeved on the sliding rod 20 for resetting the limiting block 21; and a driving mechanism arranged on the partition wall 1 and the connecting plate 30 for driving the connecting block 30 to move.

[0047] In the embodiment, when the connecting plate 30 moves away from the support frame 7, the set of limiting blocks 21 contact and clamp the two sides of the grid 2, thereby limiting the position of the grid 2; when the old grid 2 is removed and the new grid 2 is installed, the new grid 2 is only needed to be placed between the two limiting blocks 21, the two limiting blocks 21 limit the position of the new grid 2, ensure that the new grid 2 is aligned with the through hole on the support frame 7, then the operator can conveniently fix the grid 2 on the support frame 7 through the connecting plate 30 and the bolts, and the operator can more easily place the grid 2 in the correct position through the limiting effect of the limiting mechanism, without complex alignment and adjustment work, thereby simplifying the installation process.

[0048] In the further preferred embodiment of the application, the driving mechanism comprises: a connecting box 23 fixedly installed on the top of the installation opening; a threaded rod 24 rotatably installed in the connecting box 23; a threaded cylinder 25 threadedly sleeved on the threaded rod 24, the top of the threaded cylinder 25 being fixedly installed with a Z-shaped block 26, the Z-shaped block 26 penetrating through the top of the support frame 7 and being fixedly connected with the connecting block 19; a driven gear two 27 rotatably installed on one side of the connecting box 23; a rack two 28 fixedly installed in the slot of the connecting plate 30, the rack two 28 being engaged with the driven gear two 27; two conical gears two 29 fixedly sleeved on the rotating shafts of the threaded rod 24 and the driven gear two 27, respectively, the two conical gears two 29 being engaged with each other.

[0049] In the embodiment, when the connecting plate 30 moves upward, the rack two 28 is synchronously moved, thereby driving the driven gear two 27 to rotate, when the driven gear two 27 rotates, the rotating force of the driven gear two 27 is transmitted to the threaded rod 24 through the conical gears two 29, so that the threaded rod 24 rotates, the rotation of the threaded rod 24 drives the threaded cylinder 25 to move left and right in the horizontal direction, thereby synchronously moving the connecting block 19 and the limiting block 21 through the Z-shaped block 26, when the connecting plate 30 moves away from the support frame 7, the limiting block 21 contacts and clamps the two sides of the grid 2, thereby limiting the grid 2, through the design of the driving mechanism, the automatic limiting function in the installation process of the grid 2 is realized, the operator does not need to manually adjust the position of the limiting block 21, only needs to place the grid 2 in the correct position and fix the connecting plate 30.

[0051] In this embodiment, the setting of the arc-shaped part makes the grid 2 more smooth when inserted between the two limiting blocks 21, reduces friction and resistance during installation, improves the convenience of installation, and the rectangular threaded cylinder 25 can more effectively resist torsion and deviation, ensuring the accuracy and stability of the limiting block 21 during movement, improving the reliability and safety of the entire device.

[0052] In further preferred embodiments of the present application, the U-shaped frame 5 is installed with a baffle 54 on both sides, and a plurality of connecting pipes 50 for removing filler 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 cleaning, ensuring the cleanliness and efficiency of the cleaning work, and connecting the U-shaped frame 5 to the water pump through the connecting pipe 50 realizes fast and thorough cleaning of the filler, and the use of the connecting pipe 50 with the water pump can quickly suck out the filler on the U-shaped frame 5 and the grid 2, greatly improving the cleaning efficiency, and the strong suction of the water pump can ensure that the filler on the U-shaped frame 5 and the grid 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-mentioned scheme, the present scheme also has the following embodiments:

[0056] In this embodiment, when the one-way screw 8 rotates, the driving sprocket 39 on it rotates synchronously, and since a group of driving sprockets 39 are connected by the chain 40, when one driving sprocket 39 rotates, it will drive other driving sprockets 39 to rotate synchronously through the chain transmission, so that a group of one-way screws 8 can realize synchronous operation, and since the cleaning brush 6 and the surface detection mechanism 33 are respectively installed on the sliding block 9 and the mounting plate 32, and the movement of the sliding block 9 is driven by the one-way screw 8, when a group of one-way screws 8 synchronously operate, the cleaning brush 6 and the surface detection mechanism 33 will also move synchronously, and this design ensures that the cleaning brush 6 can clean the surface of the grid 2 while the surface detection mechanism 33 can detect the protrusions on the surface of the grid 2 in real time.

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

[0058] In the present embodiment, when the detection wheel 35 moves on the surface of the grid 2, if the filler adheres to the surface of the grid 2 and cannot be cleaned by the cleaning brush 6, the surface of the grid 2 will be uneven, at this time, the detection wheel 35 will be affected by the uneven surface and displace, thereby driving the fixed plate 36 and the displacement sensor 38 to move together, the displacement sensor 38 can detect the displacement change in real time and transmit the signal to the control system, so as to realize accurate detection of the surface defects of the grid 2. Through the setting of the compression spring 37, the detection wheel 35 can always move along the grid 2, and accurate detection can be realized even if the surface of the grid 2 is uneven. Through the displacement sensor 38, the displacement change of the detection wheel 35 can be detected in real time, and the signal can be transmitted to the control system, so as to realize accurate detection of the surface defects of the grid 2.

[0060] In the present embodiment, when the U-shaped frame 5 moves towards the surface of the grid 2 (realized by driving of the unidirectional screw rod 8), the linkage mechanism synchronously drives the support rod 42 to rotate, so that the support rod 42 drives the fixed part 43 and the flow velocity probe 44 to rotate together until the flow velocity probe 44 extends into the sewage pool to monitor the flow velocity of the water flow on the drainage side of the grid 2 in real time. Through real-time monitoring of the flow velocity of the water flow on the drainage side of the grid 2 by the flow velocity probe 44, the flow information can be accurately obtained, which provides a strong basis for subsequent cleaning or replacement of the grid 2. Through the introduction of the flow velocity monitoring mechanism, the present grid device not only has the cleaning function, but also has the function of monitoring the flow velocity in real time, thereby enhancing the practicability and functionality of the equipment.

[0061] In another embodiment of the present application, the fixing member 43 is composed of a U-shaped block 431, a pull rod 432, a set of arc-shaped 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 slidingly arranged on the U-shaped block 431, the set of arc-shaped blocks 433 are respectively installed in the pull rod 432 and the U-shaped block 431 for fixing the flowmeter probe 44 in the U-shaped block 431, 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-shaped block 433.

[0062] In the embodiment, when the pull rod 432 is pulled, the two arc-shaped blocks 433 are away from each other, and then the flowmeter probe 44 can be removed, the cooperation of the arc-shaped blocks 433 and the connecting spring 434 can realize the stable clamping of the flowmeter probe 44, and the problems of loosening or falling off caused by water flow impact during monitoring are avoided, and the adjustable design of the fixing member 43 can adapt to flowmeter probes 44 with different diameters, thereby improving the applicability and flexibility of the equipment.

[0063] In another embodiment of the present application, the linkage mechanism comprises a set of differential gears two 45 respectively installed on the rotating shafts of the fixing box 41 and the support rod 42, a set of the differential gears two 45 are in meshing connection, two differential chain wheels 46 are respectively fixedly sleeved on the single-way screw rod 8 and the rotating shafts of the differential gears two 45 located on the fixing box 41, and a chain two 47 is sleeved on the two differential chain wheels 46.

[0064] In the embodiment, when the single-way screw rod 8 starts to rotate under the action of the driving mechanism, the rotating force is first transmitted to the differential chain wheel 46 fixedly connected with the single-way screw rod 8, and then the rotating force is transmitted to the differential gear two 45 located on the fixing box 41 through the chain two 47, and the differential gear two 45 is further driven to rotate, and since the differential gears two 45 and the gear on the rotating shaft of the support rod 42 are in meshing connection, the support rod 42 also rotates.

[0065] When the single-way screw rod 8 drives the sliding block 9 to slide to the limit position, the rotating angle of the support rod 42 is limited between 90-115 degrees due to the differential action of the gear, which not only ensures that the flowmeter probe 44 can smoothly extend into the sewage pool for monitoring, but also avoids the problems of mechanism damage or inaccurate monitoring caused by excessive rotation, and through the design of the linkage mechanism, the synchronous rotating drive between the single-way screw rod 8 and the support rod 42 is ensured, so that the flowmeter probe 44 can extend into the sewage pool for monitoring synchronously with the movement of the U-shaped frame 5.

[0066] In another embodiment of the present invention, a filtering mechanism for filtering the filler 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 the filler is provided 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 filtration. 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 filtration 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 filtration efficiency.

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

[0069] In this embodiment, when the filter cartridge 49 needs to be installed in the filter box 48, it is only necessary to move the filter cartridge 49 close to the magnet bar 53 and use the adsorption force of the magnet to easily position the filter cartridge 49 on the limit plate 52 without the need for additional fixing devices or operating steps. Similarly, when the filter cartridge 49 needs to be removed or replaced, it is only necessary to overcome the adsorption force of the magnet to easily remove the filter cartridge 49 from the filter box 48.

[0070] In another embodiment of the present invention, a connecting plate 55 is fixedly installed on one side of the bracket 3. 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 the embodiment, when the one-way screw 8 starts to drive the installation plate 32 to move, the roller 56 will roll along the adapter plate 55, and when the roller 56 rolls and contacts the inclined part of the adapter plate 55, the adapter plate 55 will move to the rear side (here, the "rear side" is relative to the moving direction of the installation plate 32) due to the guiding effect of the inclined part, and at the same time, the connecting spring 18 will be deformed due to the movement of the adapter plate 55, which plays a buffering and adjusting role, which ensures that when the roller 56 rolls on the adapter plate 55, especially when it contacts the inclined part, it can smoothly transition and will not produce sudden impact or jam. Through the special design of the adapter plate 55 and the rolling of the roller 56, and the deformation of the connecting spring 18, it can be ensured that the installation plate 32 will not directly collide with the aeration pipe 4 during movement, which protects the aeration pipe 4 from being damaged due to collision.

[0072] In summary, compared with the related art, the device effectively solves the problems of filler accumulation and blockage during the operation of the existing grid device through the cooperation of aeration flushing, a U-shaped frame and a cleaning brush.
