Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically, it relates to an integrated aerobic three-phase separation sedimentation device. Background Technology

[0002] Aerobic three-phase separation is a wastewater treatment technology that utilizes aerobic microorganisms to decompose organic matter in an oxygen-rich environment and then efficiently separates the gas, solid, and liquid phases generated during the treatment process using a specific device. This technology improves wastewater treatment efficiency, enables effective resource recovery and reuse, and reduces pollutant emissions.

[0003] Patent CN218755242U discloses an aerobic three-phase separator that allows for convenient cleaning of the overflow weir without requiring the separation chamber to be moved. While this device can clean the overflow weir, the moving column is not fixed because it is movably fitted into the moving groove. Consequently, the overflow weir is also not fixed. During and after the sewage is added to the separation chamber, the sewage exerts impact and buoyancy on the overflow weir. Under the influence of these forces, gaps appear between the second support hole of the overflow weir and the upper end of the connecting pipe. Unfiltered sewage can then enter the connecting pipe through these gaps and be discharged, thus affecting the quality of the discharged water. Utility Model Content

[0004] To address the technical problem of gaps between the second support hole and the upper end of the connecting pipe affecting the quality of discharged water, this utility model provides an integrated aerobic three-phase separation sedimentation device.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An integrated aerobic three-phase separation sedimentation device includes: an aerobic tank; a sedimentation tank located inside and above the aerobic tank; a sealing plate located at the lower opening of the sedimentation tank; an overflow weir located inside and above the sedimentation tank; an outlet located in the middle of the overflow weir; an outlet pipe connected to the lower part of the sedimentation tank, with its upper end corresponding to the outlet and its lower end penetrating the aerobic tank; a filter plate installed above the overflow weir; and symmetrically arranged sleeves connected inside the aerobic tank below the overflow weir, with symmetrically arranged sliding rods connected to the lower surface of the overflow weir at positions corresponding to the sleeves, the sliding rods being slidably connected to the sleeves. Inside the sleeve: A pressing block is installed at the bottom inside the sleeve. A first spring connects the pressing block and the sleeve. A symmetrically arranged L-shaped positioning arm is installed above the pressing block. A connecting rod is connected to the lower end of the sliding rod at the position above the positioning arm. A fixing block is connected to the lower end of the connecting rod at the position below the positioning arm. The fixing block is located between the positioning arms. A rotating plate is rotatably connected to the top of one side of the pressing block. A protrusion is connected to the bottom of the rotating plate on the side away from the pressing block. A locking block is obliquely connected to the bottom of the sleeve at the position above the protrusion. A locking groove is opened in the middle of the bottom of the locking block at the position corresponding to the protrusion. The protrusion is located in the locking groove.

[0007] Preferably, a shrinkage space is provided inside the sleeve corresponding to the position of the extrusion block, and the extrusion block is slidably connected in the shrinkage space. An expansion space is provided inside the sleeve corresponding to the position above the positioning arm, and the positioning arm moves intermittently in the expansion space.

[0008] Preferably, a rotating rod is connected to the lower end of the positioning arm, and a positioning groove is opened on the extrusion block corresponding to the position of the rotating rod. The rotating rod is rotatably connected in the positioning groove. A symmetrically arranged through groove is opened in the middle of the rotating rod, and a torsion spring is installed in the through groove. The two ends of the torsion spring are respectively connected to the extrusion block and the rotating rod.

[0009] Preferably, a reset block is connected to the lower part of the sleeve corresponding to the position below the protrusion. The reset block has a first tilt angle at the position below the locking block, a second tilt angle at the middle part of the upper part of the reset block corresponding to the position of the locking groove, and a third tilt angle at the upper part of the reset block away from the position below the locking block.

[0010] Preferably, the first tilt angle is the same as the tilt angle of the card block, the second tilt angle is in the opposite direction to the first tilt angle, and the third tilt angle is the same as the first tilt angle.

[0011] Preferably, a support ring is connected to the outer side of the upper end of the outlet pipe, a telescopic sleeve is connected to the upper surface of the support ring, a third spring is connected inside the telescopic sleeve, an adsorption sealing sticker is connected to the upper surface of the telescopic sleeve, and the upper surface of the adsorption sealing sticker is in contact with the lower surface of the overflow weir.

[0012] Preferably, a symmetrically arranged outer shell is connected to the upper middle part of the outer side of the overflow weir, corresponding to the position of the filter plate. A wedge block is slidably connected inside the outer shell. The lower surface of the wedge block is in contact with the upper surface of the filter plate. A second spring is connected between the wedge block and the outer shell. A lever is connected to the upper surface of the wedge block. A movable groove is opened in the outer shell corresponding to the position of the lever. The lever is slidably connected in the movable groove.

[0013] Preferably, a first chamfer is symmetrically arranged below the fixing block, and a second chamfer is symmetrically arranged at the opening above the sleeve corresponding to the position of the first chamfer. The first chamfer and the second chamfer are used in conjunction.

[0014] The beneficial effects of this utility model are:

[0015] When fixing the overflow weir, the sliding rod is inserted into the sleeve. After the sliding rod enters the sleeve, the fixing block will contact the upper surface of the extrusion block. By pressing down the overflow weir, the sliding rod and the fixing block move downwards. After the fixing block moves downwards, it will compress the extrusion block. The extrusion block, under compression, will compress the first spring. After being compressed, the first spring will contract and store its restoring force. At the same time as the extrusion block moves downwards, the inclined locking block will cause the rotating plate to rotate and move downwards below the locking block. The positioning arm will then enter the contraction space. Under the action of the contraction space, the two positioning arms will move closer together, so that the fixing block is located between the two positioning arms. During the process of pressing down the overflow weir and then releasing it, the squeezing block will be reset under the action of the first spring's restoring force. During the reset process, the squeezing block, in conjunction with the inclined locking block and the first tilt angle, will send the protrusion into the locking groove below the locking block. At this time, the squeezing block is fixed, and the positioning arm is in the contraction space, thereby fixing the fixing block. After the fixing block is fixed, the position of the sliding rod and the overflow weir is fixed, thus completing the installation of the overflow weir. The overflow weir will not be affected by the impact force and buoyancy of sewage, and there will be no gap between the outlet below the overflow weir and the outlet pipe, which can ensure the quality of the discharged water.

[0016] When the overflow weir needs to be removed for cleaning, press down on the overflow weir again. The overflow weir moves down, causing the fixing block to squeeze the squeezing block. After being squeezed, the squeezing block will drive the rotating plate to move down. After the rotating plate moves down, with the cooperation of the second tilt angle, the lower end of the rotating plate will rotate to a position away from the slot. After pressing down on the overflow weir and then releasing the overflow weir, the squeezing block will be reset under the action of the first spring's restoring force. During the reset process of the squeezing block, it will drive the rotating plate and the positioning arm to move up. With the cooperation of the third tilt angle and the tilted locking block, the rotating plate will be guided above the locking block. After the rotating plate moves to the position above the locking block, the squeezing block loses its fixation. After the positioning arm moves up, it will enter the unfolding space, allowing the positioning arm to unfold. After the positioning arm unfolds, the fixing block loses its fixation, thus causing the overflow weir to lose its fixation. At this time, the sliding rod can be removed from the sleeve to clean the overflow weir. The operation is simple and convenient.

[0017] During the installation of the overflow weir, the overflow weir compresses the third spring. The third spring, under compression, contracts and stores restoring force. After the overflow weir is installed, the protrusion will be in the slot, and the third spring will always be in a contracted state. Under the action of the restoring force, the third spring will compress the overflow weir upward. After the overflow weir receives the upward compressive force, it will transfer the force to the protrusion, giving the protrusion an upward force. Thus, with the cooperation of the third spring and the first spring, the protrusion will be more stably positioned in the slot, preventing the overflow weir from being affected by the impact force or buoyancy of sewage.

[0018] When the filter plate is placed into the overflow weir, its lower surface contacts and presses against the wedge block. The wedge block, under pressure, slides into the housing. During this process, it compresses the second spring, causing it to contract and store restoring force. After the filter plate is placed in the overflow weir and contacts the placement plate, it stops pressing against the wedge block, which then resets under the restoring force of the second spring. Once reset, the filter plate is positioned between the wedge block and the placement plate, thus securing it. To remove the filter plate, the two levers are moved, causing the two wedge blocks to slide into the housing. Once inside, the filter plate is no longer obstructed by the wedge blocks. The filter plate can then be lifted using the pull rod and removed from the overflow weir. This process is convenient, requiring no tools and improving efficiency. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1 - Figure 8 As shown, an integrated aerobic three-phase separation sedimentation device includes an aerobic tank 1 for treating sludge impurities.

[0039] A sedimentation tank 11 is installed above the aerobic tank 1 to settle sludge and impurities in the sewage.

[0040] The sedimentation tank 11 is connected to symmetrically arranged wing plates 12 on both sides. The aerobic tank 1 is connected to symmetrically arranged positioning rods 13 at the corresponding positions of the wing plates 12. The wing plates 12 overlap the positioning rods 13. Through the cooperation of the wing plates 12 and the positioning rods 13, the sedimentation tank 11 can be supported and its position can be defined.

[0041] The sedimentation tank 11 has openings at both the top and bottom. The top of the sedimentation tank 11 is used to add sewage, and the bottom of the sedimentation tank 11 is used to discharge sludge and impurities.

[0042] The upper part of the sedimentation tank 11 is rectangular, and the lower part of the sedimentation tank 11 is inverted trapezoidal. This arrangement facilitates the complete discharge of sludge and impurities from the sedimentation tank 11 and prevents sludge and impurities from remaining in the sedimentation tank 11.

[0043] A sealing plate 18 is installed at the lower opening of the sedimentation tank 11, and a connecting plate 19 is connected below the sealing plate 18. The sealing plate 18 can block the lower opening of the sedimentation tank 11 to prevent sewage from overflowing from the lower opening of the sedimentation tank 11 during sedimentation. The connecting plate 19 is used to assist in sending the sealing plate 18 into the lower opening of the sedimentation tank 11.

[0044] An overflow weir 14 is provided above the interior of the sedimentation tank 11 to collect the filtered wastewater.

[0045] A filter plate 17 is installed above the overflow weir 14 for filtering sewage.

[0046] Inside the overflow weir 14, above the position corresponding to the filter plate 17, a placement plate 171 is connected. The filter plate 17 is located above the placement plate 171, and the placement plate 171 is used to support the filter plate 17.

[0047] A pull rod 172 is connected to the middle of the upper surface of the filter plate 17, which facilitates the insertion of the filter plate 17 into or removal from the overflow weir 14.

[0048] A symmetrically arranged outer shell 7 is connected to the upper middle part of the outer side of the overflow weir 14, corresponding to the position of the filter plate 17. A wedge block 71 is slidably connected inside the outer shell 7. The lower surface of the wedge block 71 is in contact with the upper surface of the filter plate 17. The wedge block 71 is used to fix the position of the filter plate 17.

[0049] A second spring 72 is connected between the wedge block 71 and the outer casing 7. The second spring 72 is used to reset the wedge block 71.

[0050] A lever 73 is connected to the upper surface of the wedge block 71. The outer casing 7 has a movable groove 74 corresponding to the position of the lever 73. The lever 73 is slidably connected in the movable groove 74. The lever 73 is used to move the wedge block 71 and change its position.

[0051] In practical use, when the filter plate 17 is placed into the overflow weir 14, the lower surface of the filter plate 17 will contact the wedge block 71 and squeeze the wedge block 71. The wedge block 71 will slide into the outer shell 7 when squeezed. During the process of entering the outer shell 7, the wedge block 71 will squeeze the second spring 72. The second spring 72 will contract and store the restoring force when squeezed. After the filter plate 17 is placed into the overflow weir 14 and contacts the placement plate 171, the filter plate 17 will no longer squeeze the wedge block 71. The wedge block 71 will reset under the action of the restoring force of the second spring 72. After the wedge block 71 resets, the filter plate 17 will be between the wedge block 71 and the placement plate 171, thereby fixing the filter plate 17.

[0052] When it is necessary to remove the filter plate 17, by moving the two levers 73, the two wedge blocks 71 slide into the housing 7. After the two wedge blocks 71 are inside the housing 7, the filter plate 17 is no longer blocked by the wedge blocks 71. At this time, the filter plate 17 can be lifted by the pull rod 172 and removed from the overflow weir 14, thereby removing the filter plate 17. It is convenient to install and remove the filter plate 17 without the need for tools. The operation is simple and convenient, improving the efficiency of installation and removal.

[0053] The overflow weir 14 has symmetrically arranged inclined plates 2 integrated inside the lower part, which are used to concentrate the filtered sewage in the middle of the overflow weir 14.

[0054] An outlet 15 is provided in the middle of the overflow weir 14 for discharging filtered sewage.

[0055] A water outlet pipe 16 is connected to the bottom of the sedimentation tank 11. The upper end of the water outlet pipe 16 corresponds to the water outlet 15, and the lower end of the water outlet pipe 16 passes through the aerobic tank 1. With the cooperation of the water outlet pipe 16, the filtered sewage can be discharged from the sedimentation tank 11 through the water outlet pipe 16.

[0056] A support ring 8 is connected to the outer side of the upper end of the water outlet pipe 16. A telescopic sleeve 81 is connected to the upper surface of the support ring 8. A third spring 82 is connected inside the telescopic sleeve 81. The third spring 82 is used to squeeze the telescopic sleeve 81 so that the adsorption sealing patch 83 can be tightly attached to the lower surface of the overflow weir 14.

[0057] An adsorption sealing sticker 83 is connected to the upper surface of the telescopic sleeve 81. The upper surface of the adsorption sealing sticker 83 is attached to the lower surface of the overflow weir 14. The adsorption sealing sticker 83 is used to improve the sealing between the overflow weir 14 and the telescopic sleeve 81 to prevent the filtered sewage from overflowing.

[0058] In practical use, when installing the overflow weir 14, the overflow weir 14 will compress the third spring 82. The third spring 82 will contract and store restoring force when compressed. After the overflow weir 14 is installed, the protrusion 51 will be in the slot 53, and the third spring 82 will always be in a contracted state. Under the action of the restoring force, the third spring 82 will compress the overflow weir 14 upward. After the overflow weir 14 is subjected to the upward compressive force, it will transfer the force to the protrusion 51, so that the protrusion 51 will receive an upward force. Thus, with the cooperation of the third spring 82 and the first spring 41, the protrusion 51 will be more stably in the slot 53, so that the overflow weir 14 will not be affected by the impact force or buoyancy of sewage.

[0059] Inside the aerobic tank 1, below the overflow weir 14, there are symmetrically arranged sleeves 3. On the lower surface of the overflow weir 14, corresponding to the position of the sleeves 3, there are symmetrically arranged sliding rods 31. The sliding rods 31 are slidably connected inside the sleeves 3. Through the cooperation of the sleeves 3 and the sliding rods 31, the position of the overflow weir 14 can be initially defined.

[0060] A compression block 4 is provided at the lower part of the sleeve 3. A shrinkage space 491 is provided inside the sleeve 3 corresponding to the position of the compression block 4. The compression block 4 is slidably connected in the shrinkage space 491. A first spring 41 is connected between the compression block 4 and the sleeve 3. The first spring 41 is used to reset the compression block 4. The shrinkage space 491 is used to bring the two positioning arms 42 together.

[0061] A symmetrically arranged L-shaped positioning arm 42 is provided above the extrusion block 4 to fix the position of the fixing block 46.

[0062] An unfolding space 49 is provided inside the sleeve 3 at the position above the positioning arm 42. The positioning arm 42 moves intermittently within the unfolding space 49, which is used to unfold the two positioning arms 42.

[0063] The lower end of the positioning arm 42 is connected to a rotating rod 43. The pressing block 4 has a positioning groove 44 corresponding to the position of the rotating rod 43. The rotating rod 43 is rotatably connected in the positioning groove 44. Through the cooperation of the rotating rod 43 and the positioning groove 44, the position of the positioning arm 42 can be limited.

[0064] The rotating rod 43 has symmetrically arranged through slots 47 in the middle. A torsion spring 48 is installed in the through slot 47. The two ends of the torsion spring 48 are connected to the extrusion block 4 and the rotating rod 43 respectively. The torsion spring 48 is used to reset the extrusion arm.

[0065] A connecting rod 45 is connected to the lower end of the slide rod 31 at the position above the positioning arm 42. A fixing block 46 is connected to the lower end of the connecting rod 45 at the position below the positioning arm 42. The fixing block 46 is located between the positioning arms 42. The two positioning arms 42 can fix the position of the fixing block 46, thereby fixing the position of the slide rod 31 and the overflow weir 14.

[0066] A rotating plate 5 is rotatably connected to the upper side of one side of the extrusion block 4. A protrusion 51 is connected to the lower side of the rotating plate 5 away from the extrusion block 4. The protrusion 51 is used to assist in fixing the position of the positioning arm 42.

[0067] Inside the sleeve 3, at the lower position corresponding to the position above the protrusion 51, there is an inclined connection of a locking block 52. The lower middle part of the locking block 52 is provided with a locking groove 53 corresponding to the position of the protrusion 51. The protrusion 51 is located in the locking groove 53. Through the cooperation of the locking block 52 and the locking groove 53, the position of the protrusion 51 can be fixed.

[0068] A reset block 54 is connected to the lower part of the sleeve 3, corresponding to the position below the protrusion 51. The reset block 54 is provided with a first tilt angle 55 at the position below the locking block 52. The first tilt angle 55 is the same as the tilt angle of the locking block 52. The first tilt angle 55 is used to guide the protrusion 51 into the locking groove 53.

[0069] A second tilt angle 56 is provided at the upper center of the reset block 54 corresponding to the position of the slot 53. The tilt direction of the second tilt angle 56 is opposite to that of the first tilt angle 55. The second tilt angle 56 is used to guide the protrusion 51 out of the slot 53.

[0070] A third tilt angle 57 is provided above the reset block 54 at a position away from the lower part of the locking block 52. The tilt angle of the third tilt angle 57 is the same as that of the first tilt angle 55. The third tilt angle 57 is used to guide the protrusion 51 above the locking block 52.

[0071] A first chamfer 6 is symmetrically arranged below the fixing block 46, and a second chamfer 61 is symmetrically arranged at the opening above the sleeve 3 corresponding to the position of the first chamfer 6. The first chamfer 6 and the second chamfer 61 are used together. Through the cooperation of the first chamfer 6 and the second chamfer 61, the slide rod 31 can be sent into the sleeve 3 more accurately.

[0072] In practical use, when fixing the overflow weir 14, the sliding rod 31 is inserted into the sleeve 3. After the sliding rod 31 enters the sleeve 3, the fixing block 46 will contact the upper surface of the pressing block 4. By pressing down the overflow weir 14, the sliding rod 31 and the fixing block 46 move downward. After the fixing block 46 moves downward, it will press the pressing block 4. The pressing block 4 will press the first spring 41. After being pressed, the first spring 41 will contract and store the restoring force. At the same time as the pressing block 4 moves downward, in conjunction with the inclined locking block 52, the rotating piece 5 will rotate and move downward to below the locking block 52, and the positioning arm 42 will enter the contraction space 491. Under the action of the contraction space 491, the two positioning arms 42 will move closer, so that the fixing block 46 is located in the two fixed positions. Between the positioning arms 42, after pressing down the overflow weir 14 and then releasing the overflow weir 14, the squeezing block 4 will be reset under the action of the restoring force of the first spring 41. During the reset process, the squeezing block 4, in conjunction with the inclined locking block 52 and the first tilt angle 55, will send the protrusion 51 into the locking groove 53 below the locking block 52. At this time, the squeezing block 4 is fixed, and the positioning arm 42 is in the contraction space 491, thereby fixing the fixing block 46. After the fixing block 46 is fixed, the position of the sliding rod 31 and the overflow weir 14 is fixed, thus completing the installation of the overflow weir 14. The overflow weir 14 will not be affected by the impact force and buoyancy of sewage. There will be no gap between the outlet 15 below the overflow weir 14 and the outlet pipe 16, which can ensure the quality of the discharged water.

[0073] When the overflow weir 14 needs to be removed for cleaning, press down on the overflow weir 14 again. The overflow weir 14 moves down, causing the fixing block 46 to press against the pressing block 4. After being pressed, the pressing block 4 will drive the rotating plate 5 to move down. After the rotating plate 5 moves down, with the cooperation of the second tilt angle 56, the lower end of the rotating plate 5 will rotate to a position away from the slot 53. After pressing down on the overflow weir 14 and then releasing the overflow weir 14, the pressing block 4 will be reset under the action of the restoring force of the first spring 41. During the reset process of the pressing block 4, the rotating plate 5 and the positioning arm will be driven to reset. 42 moves upward, and the rotating plate 5, in cooperation with the inclined locking block 52 at the third tilt angle 57, will guide the rotating plate 5 to the top of the locking block 52. After the rotating plate 5 moves to the position above the locking block 52, the squeezing block 4 loses its fixation, and the positioning arm 42 moves upward and enters the unfolding space 49, so that the positioning arm 42 is unfolded. After the positioning arm 42 is unfolded, the fixing block 46 loses its fixation, so that the overflow weir 14 loses its fixation. At this time, the sliding rod 31 can be removed from the sleeve 3 to clean the overflow weir 14. The operation is simple and convenient.
