Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment from waste incinerator slag, and in particular to a wastewater treatment pond for treating waste incinerator slag. Background Technology

[0002] Waste incineration ash is an inorganic residue produced after the incineration of municipal solid waste. Its treatment and resource utilization involve multiple fields such as environmental protection, materials science, and engineering management. Wastewater is generated during the processing of waste incineration ash. During wastewater purification, the wastewater is discharged into a wastewater treatment pond for sedimentation, filtration, and flotation. In wastewater treatment, flotation is a technology that uses air bubbles to adsorb pollutants and float them to the surface to achieve solid-liquid or liquid-liquid separation. Its core principle is to utilize microbubbles to combine with suspended particles or oil droplets in the wastewater to form a "bubble-particle" complex. Because its density is less than that of water, it floats and is ultimately removed by a scraper.

[0003] Chinese patent CN220393464U discloses an aeration device for a wastewater treatment tank, including a treatment tank, a storage compartment at the bottom of the treatment tank, and an aeration pipe fixedly installed on the bottom inner side of the treatment tank. By setting up filter plates, sediment generated in wastewater can be blocked above the aeration pipes and exhaust ports, preventing impurities from clogging the exhaust ports and eliminating the need for cleaning the aeration pipes and exhaust ports. The filter plates, servo motors, and stirring paddles ensure sufficient contact between air and wastewater. Adjustable mechanisms such as the servo motor, pulleys, and screws allow for the upward adjustment of the filter plates, facilitating the cleaning of sediment and improving wastewater treatment efficiency. However, the aforementioned technologies have the following drawbacks: after bubbles form during flotation and combine with suspended particles in the wastewater, they float to the surface. Existing technologies cannot completely clean and collect all floating debris from these bubbles. Furthermore, during transport, bubbles often break due to collisions, causing impurities to adhere to the conveying device, leading to blockages over time. Therefore, a wastewater treatment pond for treating waste incinerator slag is proposed. Summary of the Invention

[0004] To prevent impurities from adhering to the surface of the conveying structure and causing blockage after air bubbles break during transportation, this invention provides a wastewater treatment pond for treating waste incinerator slag.

[0005] The present invention provides a wastewater treatment tank for treating waste incinerator slag, which adopts the following technical solution: it includes a tank body and an air bubble plate. The air bubble plate is installed on the bottom wall of the tank body. A connecting frame is provided above the tank body. A material collection and feeding structure is installed at both ends of the connecting frame. A linkage frame is slidably connected to the connecting frame.

[0015] Optionally, a damping structure is installed on the upper surface of the pool body to apply resistance to the movement of the two intermediate cylinders.

[0016] The damping structure includes two grooved plates, which are installed on the upper surface of the pool body. The upper surface of the grooved plates has multiple groove-shaped structures. The middle cylinder is located on the outer side of the outer cylinder, and both ends are fixedly sleeved with sleeve blocks. An elastic baffle is fixed on the bottom surface of the sleeve block. The lower end of the elastic baffle is located in a groove-shaped structure of an adjacent grooved plate.

[0017] Optionally, a permeable plate is provided on the lower side of the opening of the outer cylinder.

[0019] The two output ends of the dual-head motor are each fixed with a variable diameter wheel, which is divided into a large diameter end and a small diameter end, and the variable diameter wheel is located on the lower side of the bar.

[0020] Optionally, a long shaft is installed through the upper end of the partition plate, and rigid baffles are elastically rotatable on both sides of the long shaft. The rigid baffles are located on the upper side of the groove-shaped structure of the adjacent groove plate.

[0023] Two inclined blocks are fixed at both ends of the upper surface of the pool body, and the upper side of the inclined block near the connecting frame is inclined.

[0024] In summary, the present invention has the following beneficial technical effects:

[0025] This invention utilizes components such as an inner column, an outer cylinder, a middle cylinder, and a permeable deflector. A transverse power structure, via a linkage frame, drives the outer cylinder to move back and forth relative to the water surface. Floating debris on the water surface enters the outer cylinder through its opening. As the permeable deflector rotates, it pushes the floating debris into the outer cylinder upwards to the upper part of the outer cylinder. Then, the floating debris falls through the opening of the middle cylinder into a storage tank on the inner surface of the inner column. When the inner column causes the storage tank containing dirt to disengage from the opening of the middle cylinder, and then the storage tank containing dirt rotates to connect with the inflation and discharge structures, the inflation structure injects high-pressure airflow into the storage tank. The airflow carries the dirt in the storage tank out through the discharge structure. The high-pressure airflow effectively prevents dirt from adhering to and remaining in the storage tank. This invention incorporates components such as an elastic baffle, a grooved plate, and a sleeve block. The elastic baffle engages with the grooved structure of the grooved plate, which in turn resists the movement of the sleeve block and the outer cylinder. When the linkage frame reciprocates, it first approaches the outer cylinder on one side of the movement direction, causing the corresponding driving gears A and B to mesh with driven gears A and B respectively. This drives the corresponding torsion cylinder and inner column to rotate, ensuring that only the permeable baffle on one side of the movement rotates. This prevents the permeable baffle on the other side from breaking up newly generated air bubbles and suspended matter on that side when it rotates. As the linkage frame reciprocates left and right, it can repeatedly collect floating matter on the water surface. This invention utilizes a permeable plate. When the outer cylinder moves, the permeable plate on the moving side first moves to the underside of the floating objects. As the structure moves across the water surface, the resulting ripples cause air bubbles to break before entering the outer cylinder. The dirt trapped inside the bubbles falls onto the permeable plate. When the outer cylinder moves to one end of the pool, the permeable plate continues to move after contacting the inner wall of the pool. As it continues to move, the permeable plate gradually compresses the pressure elastic telescopic rod, causing the dirt on the upper side of the permeable plate to gradually enter the rotation range of the permeable plate from the opening of the outer cylinder. This effectively prevents impurities from falling back into the pool after the air bubbles break. This invention incorporates components such as a variable-diameter wheel, a partition plate, a bar, and a rigid baffle. The variable-diameter wheel on one side of the moving direction moves to the lower side of the corresponding bar. A vertical elastic telescopic rod pulls the bar into contact with the variable-diameter wheel. When the smaller diameter portion of the variable-diameter wheel contacts the bar, the bar causes the rigid baffle to insert into a groove in the grooved plate. At this point, the lower end of the partition plate contacts the upper surface of the permeable plate. The partition plate remains stationary as the outer cylinder moves, effectively blocking water flow fluctuations caused by the outer cylinder's movement and reducing bubble breakage during structural movement. When the larger diameter end of the variable-diameter wheel contacts the bar, it pushes the bar, causing the rigid baffle to detach from the grooved plate. The rigid baffle, pushed by the horizontal elastic telescopic rod, returns to its initial distance from the outer cylinder. Then, when the smaller diameter end of the variable-diameter wheel contacts the bar again, the rigid baffle re-inserts into the groove of the grooved plate. As the variable-diameter wheel rotates, the rigid baffle inserts downwards into the water surface, blocking water surface fluctuations and effectively reducing bubble breakage.

[0035] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0036] This invention discloses a wastewater treatment pond for treating waste incinerator slag. For example... Figures 1-8As shown, the system includes a tank body 1 and a bubble plate 2. The bubble plate 2 is installed on the inner bottom wall of the tank body 1 and is connected to a bubble generator. The upper surface of the bubble plate 2 is perforated. Gas is ejected through the bubble plate 2 at the bottom of the tank body 1. The upward bubbles combine with suspended particles in the wastewater. A connecting frame 3 is provided above the tank body 1. A collection and feeding structure 5 is installed at both ends of the connecting frame 3. The connecting frame 3 is slidably connected to a linkage frame 4, which can slide left and right relative to the connecting frame 3.

[0037] The upper surface of the pool body 1 is equipped with a transverse power structure 6 that controls the transverse movement of the linkage frame 4.

[0038] The transverse power structure 6 includes a threaded rod 61 and a reciprocating motor 62. The reciprocating motor 62 is fixed to the pool body 1. The output end of the reciprocating motor 62 is coaxially fixed to the threaded rod 61. The linkage frame 4 is threadedly sleeved on the outer surface of the threaded rod 61. The reciprocating motor 62 drives the threaded rod 61 to rotate. The linkage frame 4 moves back and forth left and right by meshing with the reciprocating rotating threaded rod 61.

[0039] The material collection and feeding structure 5 includes an outer cylinder 51, an intermediate cylinder 52, and an inner column 53. The outer cylinder 51 is fixed to the connecting frame 3. The inner column 53 is rotatably inserted into the inner side of the intermediate cylinder 52. The intermediate cylinder 52 is coaxially installed inside the outer cylinder 51. The upper surface of the intermediate cylinder 52 is open at one end inside the outer cylinder 51. A torsion cylinder 54 is rotatably sleeved at the front end of the intermediate cylinder 52. A water-permeable baffle 55 is fixed to the torsion cylinder 54. The water-permeable baffle 55 slides in contact with the inner wall of the outer cylinder 51. When the water-permeable baffle 55 rotates, it can move the dirt at the bottom of the outer cylinder 51 to the upper side of the intermediate cylinder 52, so that the dirt falls into the inner side of the intermediate cylinder 52 under gravity through the opening of the intermediate cylinder 52. The front end of the torsion cylinder 54 rotates through the inner wall of the outer cylinder 51. The side of the outer cylinder 51 away from the linkage frame 4 is open. The water level is controlled at the notch position of the outer cylinder 51, so that half of the notch of the outer cylinder 51 is below the water surface and the other half is above the water surface.

[0040] The inner column 53 is rotatably inserted into the middle cylinder 52. Multiple storage slots 56 are provided on the circumferential side of the inner column 53. Dirt that falls into the middle cylinder 52 falls into the storage slots 56 on the surface of the inner column 53 and the opening of the middle cylinder 52 under gravity.

[0041] The linkage frame 4 is equipped with a power torsion structure 57 that drives the inner column 53 and the torsion cylinder 54 to rotate at different speeds. The power torsion structure 57 drives the inner column 53 and the torsion cylinder 54 to rotate at different speeds.

[0042] The power torsion structure 57 includes a dual-head motor 571, a drive gear A572 and a drive gear B573. The dual-head motor 571 is fixed to the linkage frame 4. The drive gear A572 is located behind the drive gear B573. The drive gear A572 and the drive gear B573 are coaxially mounted on the output end of one side of the dual-head motor 571.

[0043] The driven gear A574 is coaxially mounted on one end of the torsion cylinder 54 in front of the outer cylinder 51, and the driven gear B575 is coaxially fixed on one end of the inner column 53 in front of the outer side of the intermediate cylinder 52.

[0044] The driving gear A572 and the driven gear A574 are on the same plane, and the driving gear B573 and the driven gear B575 are on the same plane. When the linkage frame 4 moves, the linkage frame 4 first approaches the outer cylinder 51 on the side of the moving direction, so that the driving gear A572 and the driven gear A574 mesh, and at the same time the driving gear B573 and the driven gear B575 mesh. Then the linkage frame 4 pushes the outer cylinder 51 to move synchronously.

[0045] A damping structure 7 is installed on the upper surface of the pool body 1 to resist the movement of the two intermediate cylinders 52.

[0046] The damping structure 7 includes two grooved plates 71, which are installed on the upper surface of the pool body 1. The upper surface of the grooved plates 71 has multiple groove-shaped structures. The middle cylinder 52 is located outside the outer cylinder 51, and both ends are fixedly sleeved with sleeve blocks 72. The bottom surface of the sleeve blocks 72 is fixed with an elastic baffle plate 73. The lower end of the elastic baffle plate 73 is located in a groove-shaped structure of an adjacent grooved plate 71. The groove-shaped structure of the grooved plate 71 applies resistance to the elastic baffle plate 73, ensuring that when the linkage frame 4 moves, it first approaches the outer cylinder 51 that moves in the direction of movement, so that the driving gear A572 and driving gear B573 are stably meshed with the driven gear A574 and driven gear B575 on the corresponding side, respectively.

[0047] A permeable plate 511 is provided on the lower side of the opening of the outer cylinder 51. A partition plate 513 is provided on the upper side of the end of the permeable plate 511 away from the linkage frame 4. A transverse elastic telescopic rod 514 is fixed on the upper surface of the partition plate 513. Two bars 515 are provided on the upper side of the connecting frame 3. A variable diameter wheel 517 is fixed on both output ends of the double-headed motor 571. The variable diameter wheel 517 is divided into a large diameter end and a small diameter end. The variable diameter wheel 517 is located on the lower side of the bar 515. The bar 515 and the adjacent transverse elastic telescopic rod 514 are connected. 4. Fixed, the horizontal elastic telescopic rod 514 tends to drive the partition plate 513 away from the bar 515. The bottom surface of the bar 515 is fixed with a vertical elastic telescopic rod 516. The lower end of the vertical elastic telescopic rod 516 is fixed to the connecting frame 3. The vertical elastic telescopic rod 516 has the tendency to pull the bar 515 closer to the connecting frame 3. The two ends of the bar 515 are round rods. When the driving gear A572 meshes with the driven gear B575 on the corresponding side, the bar 515 is located above the corresponding strain diameter wheel 517.

[0048] A pressure elastic telescopic rod 512 is fixed to one end of the permeable plate 511 near the linkage frame 4. The other end of the pressure elastic telescopic rod 512 is fixed to the connecting frame 3. The pressure elastic telescopic rod 512 has the tendency to push the permeable plate 511 away from the connecting frame 3. The upper surface of the permeable plate 511 is tangent to the lower side of the inner ring surface of the outer cylinder 51. When the connecting frame 3 and the outer cylinder 51 are moving, the permeable plate 511 is located below the floating objects on the water surface. When the bubbles caused by the water surface stirring when the outer cylinder 51 moves burst, the dirt falls onto the upper side of the permeable plate 511, preventing the dirt from falling back into the pool body 1. When the permeable plate 511 continues to move after one end of the pool body 1 contacts one side of the pool body 1, the permeable plate 511 gradually compresses the pressure elastic telescopic rod 512, so that the dirt on the upper side of the permeable plate 511 gradually moves into the opening range of the outer cylinder 51.

[0049] A long shaft 518 is installed through the upper end of the partition plate 513. Rigid baffles 519 are elastically rotatable on both sides of the long shaft 518. The rigid baffles 519 are connected to the long shaft 518 via torsion springs, tending to keep the rigid baffles 519 in a vertical position. The rigid baffles 519 are located on the upper side of the grooved structure of the adjacent grooved plate 71. The lower end of the rigid baffle 519 is inclined on the side away from the connecting frame 3. The inner walls on both sides of the upper side of the grooved structure of the grooved plate 71 are outwardly flared and inclined, facilitating the insertion of the rigid baffles 519 into the grooved structure of the adjacent grooved plate 71 when it moves downward. When the bar 515 is located in the small diameter portion of the variable diameter wheel 517, the corresponding rigid baffle 519 is located within the grooved structure of the grooved plate 71, simultaneously separating... The lower end of plate 513 contacts the upper surface of permeable plate 511. At this time, when the outer cylinder 51 moves, the partition plate 513 cannot move due to the obstruction of the groove structure of grooved plate 71 by the hard baffle 519. This causes the outer cylinder 51 to gradually approach the partition plate 513, thereby blocking the water surface ripples generated by the movement of the outer cylinder 51. This effectively reduces the water surface ripples that cause bubble bursts. When the large diameter end of the variable diameter wheel 517 contacts the bar 515, it pushes the bar 515 to drive the hard baffle 519 to separate from the grooved plate 71. At the same time, the partition plate 513 separates from the water surface. The hard baffle 519 returns to the initial distance between itself and the outer cylinder 51 under the push of the transverse elastic telescopic rod 514, ensuring that the partition plate 513 will not push the water surface when it moves laterally.

[0050] A stop bar 5110 is provided on the side of the rigid baffle 519 near the connecting frame 3. The stop bar 5110 is fixed to the adjacent long shaft 518. The width of the rigid baffle 519 is smaller than the width of the groove structure of the groove plate 71. The stop bar 5110 makes the rigid baffle 519 only rotate away from the connecting frame 3. When the outer cylinder 51 moves, the rigid baffle 519 on the side opposite to the direction of movement of the outer cylinder 51 rotates relative to the long shaft 518 when it moves with the partition plate 513. This can drive the rigid baffle 519 to continuously detach from the different groove structures of the groove plate 71.

[0051] Two inclined blocks 5111 are fixed at both ends of the upper surface of the pool body 1. The upper side of the inclined block 5111 near the connecting frame 3 is inclined. When the hard baffle 519 drives the long shaft 518 to move to both ends of the pool body 1, the long shaft 518 moves upward through the inclined surface of the inclined block 5111, driving the partition plate 513 to move to the upper side of the pool body 1. At the same time, the hard baffle 519 disengages from the groove plate 71.

[0052] An inflation structure 58, which communicates with the interior of the intermediate cylinder 52, is installed at the front end of the linkage frame 4. The inflation structure 58 includes an inner blocking plate 581 and a sleeve 582. The sleeve 582 is slidably fitted onto the outer surface of the inner blocking plate 581. An air pump 583 is connected to the side of the sleeve 582 away from the linkage frame 4. The linkage frame 4 is fixed to the sleeve 582. A connecting pipe 584 is connected to the front end of the intermediate cylinder 52. The inner blocking plate 581 is fixedly fitted onto the outer surface of the connecting pipe 584. When the linkage frame 4 moves relative to the connecting frame 3, the sleeve 582 is connected to the two connecting pipes 584 respectively. The air pump 583 injects high-pressure airflow into the connected intermediate cylinder 52 through the sleeve 582 and the connecting pipes 584.

[0053] The other end of the linkage frame 4 is equipped with a discharge structure 59 that is connected to the rear end of the intermediate cylinder 52. The discharge structure 59 includes a longitudinal plate 591 and a feed box 592. The feed box 592 is slidably sleeved on the outer surface of the longitudinal plate 591, and the longitudinal plate 591 is fixedly sleeved on the outer surface of the intermediate cylinder 52. A discharge pipe 593 is installed through the end of the feed box 592 away from the linkage frame 4. The linkage frame 4 is fixed to the feed box 592. When the linkage frame 4 moves, it drives the feed box 592 to connect with the intermediate cylinder 52 on one side of the moving direction. At the same time, it is connected to the connecting pipe 584 through the corresponding storage tank 56. After the air pump 583 fills the connected storage tank 56 with high-pressure airflow through the connecting pipe 584, the airflow carries dirt from the storage tank 56 into the feed box 592, and then sprays it out from the discharge pipe 593 connected to the feed box 592. The airflow effectively prevents dirt from remaining in the storage tank 56.

[0054] The working principle is as follows: Gas is ejected from the bubble plate 2 at the bottom of the tank 1. The upward-moving bubbles combine with suspended particles in the wastewater, causing the particles to float to the surface. The water surface is controlled at the opening of the outer cylinder 51, so that half of the opening of the outer cylinder 51 is below the water surface and the other half is above the water surface. When the transverse power structure 6 drives the outer cylinder 51 to move horizontally across the water surface via the linkage frame 4, the floating objects on the water surface enter the interior of the outer cylinder 51 through the opening. Then, the torsion cylinder 54 rotates, causing the permeable baffle 55 to rotate. As the permeable baffle 55 rotates, it causes the floating objects inside the outer cylinder 51 to move upward within the outer cylinder 51. When the floating object moves to the opening of the intermediate cylinder 52, it falls into the intermediate cylinder 52 under gravity. When the inner column 53 rotates, the dirt that falls into the intermediate cylinder 52 falls into the storage tank 56 connected to it. When the inner column 53 causes the storage tank 56 containing dirt to be misaligned with the opening of the intermediate cylinder 52, and then the storage tank 56 containing dirt rotates to connect with the inflation structure 58 and the discharge structure 59, the inflation structure 58 sprays high-pressure air into the storage tank 56. The airflow carries the dirt in the storage tank 56 out of the discharge structure 59, and the airflow reduces the dirt residue in the storage tank 56.

[0055] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
