Detailed Implementation

[0019] This application discloses a ventilation and deodorization device for a wastewater treatment plant. The extension and retraction of the electric push rod 52 drives the first slider 51 to slide and the swing rod 543 to swing, so that the nozzle 60 can slide along the slide groove 40 and swing with the swing rod 543. In conjunction with the sliding of the protrusion 546 in the spiral guide groove, the nozzle 60 is driven to rotate. The spray range of the nozzle 60 can be flexibly adjusted, which can effectively expand the spray range, improve the cleaning effect of odor and effectively regulate the humidity of the biological filter 10.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3This embodiment provides a wastewater treatment plant ventilation and deodorization device, including a biological filter 10. A support 20 is provided on the top of the biological filter 10. The biological filter 10 includes a tank body 11, a support plate 12, ventilation holes 13, and air inlets 14. The tank body 11 is located at the bottom of the support 20, and the support plate 12 is located inside the tank body 11, forming a receiving cavity between the support plate 12 and the bottom of the tank body 11. Multiple ventilation holes 13 are formed on the support plate 12, and air inlets 14 are formed at the bottom of the biological filter 10. The bottom of the support 20 is movable. The system is connected to a nozzle 60, which has multiple water outlets arranged in a circular array on its circumferential side. A support plate 12 is used to place packing material, which is made of mussel shells. Microorganisms attach and grow on it. Odors enter the containment cavity through the air inlet 14 and diffuse outwards, facilitating rapid purification of odors. The gas rises through the vent 13 and is purified by contacting the biofilm attached to the surface of the packing material in the biological filter 10 during its ascent. The multiple water outlets arranged in a circular array allow the sprayed water to be scattered 360 degrees into the tank body 11.

[0022] Please refer to Figures 1-4The bracket 20 has a first through hole 30, and both sides of the inner wall of the first through hole 30 have sliding grooves 40. The bracket 20 is equipped with an adjustment mechanism 50, which includes a first slider 51, an electric push rod 52, a transmission assembly 53, and a swing assembly 54. The first slider 51 is slidably connected to the two sliding grooves 40. The electric push rod 52 is mounted on the bracket 20, and one end of the electric push rod 52 is fixedly connected to the first slider 51. The swing assembly 54 is mounted on the first slider 51 and is used to drive the nozzle 60 to swing. The system includes a rotating plate 541, a second slider 542, a rocker arm 543, a fixing block 544, a connecting block 545, a protrusion 546, a second rotating shaft 547, a collar 548, and a third rotating shaft 549. The rotating plate 541 is rotatably connected to the inside of the first slider 51, the second slider 542 is rotatably connected to one end of the rotating plate 541, the rocker arm 543 is movably connected to the inside of the second slider 542, and the nozzle 60 is disposed at the bottom of the rocker arm 543. The fixing block 544 is fixedly disposed at the top of the first slider 51, and the connecting block 545 is rotatably connected to the fixing block 544. On one side, the top of the rocker arm 543 is movably connected to the inside of the connecting block 545. The third rotating shaft 549 is located at one end of the rotating plate 541, and the second slider 542 is sleeved on and rotatably connected to the third rotating shaft 549. The bracket 20 is provided with a transmission assembly 53 for driving the rotating plate 541 to rotate. When the rotating plate 541 rotates and drives the second slider 542 to make a circular motion, the second slider 542 rotates around the third rotating shaft 549, thereby changing the angle of the second slider 542. This allows the angle of the rocker arm 543 to change with the rotation of the second slider 542, thus enabling... The second slider 542 always moves on the swing rod 543. The extension and retraction of the electric push rod 52 drives the first slider 51 to slide on the slide groove 40 in the bracket 20, thereby driving the nozzle 60 at the bottom of the first slider 51 to slide along the first through hole 30. The rotation of the rotating plate 541 drives the second slider 542 to make a circular motion. The second slider 542 drives the swing rod 543 to swing around the fixed block 544 as the axis, which flexibly adjusts the spray range of the nozzle 60, effectively expanding the spray range, improving the odor cleaning effect and effectively regulating the humidity of the biological filter.

[0023] Please refer to Figures 1-4The transmission assembly 53 includes a rack 531, a first bevel gear 533, a second bevel gear 534, and a first rotating shaft 535. The rack 531 is fixedly disposed inside the slide groove 40. A spur gear 532 is meshed with the top of the rack 531. The first bevel gear 533 is rotatably mounted on a connecting plate on one side of the first slider 51, and the first bevel gear 533 is fixedly connected to the spur gear 532. The spur gear 532 is disposed on the side of the first bevel gear 533 near the middle of the first slider 51. The second bevel gear 534 is rotatably disposed on the side of the first slider 51 away from the electric push rod 52, and the second bevel gear 534 is meshed with the first bevel gear 533. The first rotating shaft 535 is fixed. The first bevel gear 533 is fixedly connected to the rotating plate 541 at one end of the first rotating shaft 535. During the reciprocating horizontal sliding of the first slider 51 driven by the electric push rod 52, the spur gear 532 meshes with the rack 531, and the spur gear 532 drives the first bevel gear 533 to rotate. During the rotation of the first bevel gear 533, the second bevel gear 534 meshing with it is driven to rotate. The second bevel gear 534 is fixed to the rotating plate 541 through the first rotating shaft 535, thereby realizing that the rotation of the rotating plate 541 drives the second slider 542 to make a circular motion around the first rotating shaft 535. This allows the extension and retraction of the electric push rod 52 to drive the swing rod 543 to swing, increasing the spray range of the nozzle 60 and improving the cleaning effect on odors.

[0024] Please refer to Figures 1-4 The second slider 542 has a sliding hole, and the rocker arm 543 is movably connected to the inside of the sliding hole. A protrusion 546 is provided on the inner wall of the sliding hole, and a spiral guide groove is provided on the peripheral side of the rocker arm 543. The protrusion 546 is slidably connected to the spiral guide groove. The second slider 542 slides back and forth along the length direction of the rocker arm 543. Through the sliding cooperation between the protrusion 546 and the spiral guide groove, the rocker arm 543 slides back and forth in the second slider 542 while rotating, thereby realizing the rotation of the nozzle 60. The spray range is further expanded by the rotational inertia.

[0025] Please refer to Figures 1-4 A second rotating shaft 547 is rotatably connected to one side of the fixed block 544. A connecting block 545 is fixedly connected to the end of the second rotating shaft 547 away from the fixed block 544. A second through hole is provided on the connecting block 545. A collar 548 is sleeved on the swing rod 543. An annular groove communicating with the second through hole is provided in the connecting block 545. The cooperation between the collar 548 and the annular groove allows the swing rod 543 to swing only around the axis of the second rotating shaft 547, thereby expanding the spray range and restricting the sliding of the swing rod 543 in the second through hole.

[0026] The functional principle of this application can be explained through the following methods:

[0027] In use, when the electric push rod 52 is activated, it drives the first slider 51 to reciprocate horizontally. Because the spur gear 532 meshes with the rack 531, the spur gear 532, which slides on the rack 531, rotates. The spur gear 532 drives the first bevel gear 533, which is fixedly connected to it, to rotate. During the rotation of the first bevel gear 533, it drives the second bevel gear 534, which meshes with it, to rotate. The second bevel gear 534 is fixed to the rotating plate 541 via the first rotating shaft 535, thus enabling the rotating plate 541 to rotate, causing the second slider 542 to perform circular motion around the first rotating shaft 535. The second slider 542 rotates around the third rotating shaft 549. The second slider 542 adjusts its angle as it rotates, always moving on the swing rod 543. This causes the second slider 542 to drive the swing rod 543 to swing around the connecting block 545 as the axis. The second slider 542 and the swing rod 543 slide relative to each other, allowing the protrusion 546 to slide and engage with the spiral guide groove. This allows the swing rod 543 to slide back and forth within the second slider 542 while also rotating, enabling flexible adjustment of the spray range of the nozzle 60. This effectively expands the spray range, improves the cleaning effect of odor, and effectively regulates the humidity of the biological filter 10. It has the effects of effective deodorization, flexible adjustment, expanded cleaning range, and simple and practical use.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.

[0029] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto.
