Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a cascading aeration device. Background Technology

[0002] Aeration is a crucial step in wastewater treatment, aiming to introduce oxygen into the wastewater to meet the metabolic needs of aerobic microorganisms and promote the decomposition and transformation of organic matter. Traditional aeration methods mainly include using rotating discs, surface aerators, and blowers for aeration and reoxygenation, all of which consume significant amounts of energy.

[0003] Existing technology CN204848417U discloses a cascading aeration and reoxygenation device, including a support member, a collection tank, a baffle plate, and at least two cascading plates with cascading holes. The support member is located on one side of the cascading aeration and reoxygenation device, and all cascading plates are arranged on the same side of the support member. All cascading plates are stacked vertically, and water falling from the cascading holes of the upper cascading plate falls onto the surface of the adjacent lower cascading plate. The collection tank is located at the bottom of the cascading aeration and reoxygenation device, and a baffle plate is provided in the collection tank, dividing the collection tank into an inlet area and an outlet area that are interconnected at the bottom. The outlet area has an outlet. This utility model utilizes the water level rise for aeration and reoxygenation, achieving zero energy consumption. By opening holes in the cascading plates and using a multi-layered cascading plate arrangement to stagger the cascading holes, the surface area of ​​the water during the falling process is increased, improving the contact area with air, thereby enhancing the aeration and reoxygenation effect.

[0004] Regarding the aforementioned cascading aeration and reoxygenation device, since different water qualities have different requirements for aeration and reoxygenation, and the spacing between the two cascading plates in the existing technology is fixed and cannot be adjusted, it is difficult to make corresponding adjustments according to different water qualities, resulting in poor applicability. Utility Model Content

[0021] In this embodiment, the collection pool 101, the support plate 102, the first drop plate 103, and the second drop plate 104 are all existing technologies. Through the control component, the problem of poor applicability is solved because different water qualities have different aeration and reoxygenation requirements, while the spacing between the two drop plates in the existing technology is fixed and cannot be adjusted according to different water qualities.

[0022] The first adjusting seat 105 and the second adjusting seat 106 are both connected to the support plate 102 via the guide member.

The first drop plate 103 is detachably mounted on the first adjusting seat 105, and the second drop plate 104 is detachably mounted on the second adjusting seat 106. The scale mark 110 is disposed on the support plate 102 and located on the side of the support plate 102 closest to the first adjusting seat 105. The control member controls the movement of the first adjusting seat 105 and the second adjusting seat 106. Both the first adjusting seat 105 and the second adjusting seat 106 are elongated rectangular bodies. Both the first adjusting seat 105 and the second adjusting seat 106 are connected to the support plate 102 via the guide member. Under the action of the guide member, both the first adjusting seat 105 and the second adjusting seat 106 can move on the support plate 102. The first adjusting seat 105 is located above the second adjusting seat 106. The first drop plate 103 and the second drop plate 104 are respectively bolted to the first adjusting seat 105 and the second adjusting seat 106. The drop holes on the second drop plate 104 are misaligned with the drop holes on the first drop plate 103. The scale mark 110 is engraved on the support plate 102 along the length direction of the support plate 102. The highest point of the first drop plate 103 is aligned with the zero mark of the scale mark 110. The control component can control the first adjusting seat 105 and the second adjusting seat 106 to move synchronously in opposite directions. Through the control component, the distance between the first drop plate 103 and the second drop plate 104 can be flexibly adjusted, which solves the problem that the distance between the two drop plates in the prior art is fixed and cannot be adjusted according to different water qualities, resulting in poor applicability.

The guide rail 107 is arranged on the support plate 102 along the length direction of the support plate 102, and there are two of them, which are parallel to each other. The first adjusting seat 105 is slidably connected to the guide rail 107 through the first sliding sleeve 108, and the second adjusting seat 106 is slidably connected to the guide rail 107 through the second sliding sleeve 109. Through the guide member, the movement of the first adjusting seat 105 and the second adjusting seat 106 is guided.

[0024] Meanwhile, the first threaded sleeve 111 is fixedly connected to the first adjusting seat 105 and is located on the side of the first adjusting seat 105 away from the first drop plate 103; the second threaded sleeve 112 is fixedly connected to the second adjusting seat 106 and is located on the side of the second adjusting seat 106 away from the second drop plate 104; the adjusting member drives the first threaded sleeve 111 and the second threaded sleeve 112 to move. The first threaded sleeve 111 has a threaded through hole, and the second threaded sleeve 112 has a threaded through hole. The adjusting member is mounted on the support plate 102 and is used to drive the first threaded sleeve 111 and the second threaded sleeve 112 to move synchronously. Through the movement of the first threaded sleeve 111 and the second threaded sleeve 112, the first adjusting seat 105 and the second adjusting seat 106 are moved.

[0025] In addition, the bidirectional screw 113 is rotatably connected to the support plate 102 and threadedly connected to the first threaded sleeve 111 and the second threaded sleeve 112 respectively; the control knob 114 is fixedly connected to the bidirectional screw 113 and is located at one end of the bidirectional screw 113. The bidirectional screw 113 is vertically mounted on the support plate 102 through a bearing bracket. The thread directions at both ends of the bidirectional screw 113 are opposite. The first threaded sleeve 111 and the second threaded sleeve 112 are respectively sleeved on both ends of the bidirectional screw 113. The control knob 114 facilitates the rotation of the bidirectional screw 113. By turning the control knob 114, the first threaded sleeve 111 and the second threaded sleeve 112 can be driven to move synchronously in opposite directions.

[0026] Finally, the first corner plate 115 is detachably connected to the first adjusting seat 105 and detachably connected to the first drop plate 103; the second corner plate 116 is detachably connected to the second adjusting seat 106 and detachably connected to the second drop plate 104.

Through the first corner plate 115 and the second corner plate 116, the first drop plate 103 and the second drop plate 104 are provided with auxiliary support, thereby improving stability.

[0027] In this embodiment, when it is necessary to adjust the distance between the first drop plate 103 and the second drop plate 104, the control knob 114 is turned, the bidirectional screw 113 rotates, and drives the first threaded sleeve 111 and the second threaded sleeve 112 to move synchronously in opposite directions. The first adjusting seat 105 and the second adjusting seat 106 then drive the first drop plate 103 and the second drop plate 104 to move, thereby realizing the adjustment of the distance between the first drop plate 103 and the second drop plate 104. This solves the problem that the distance between the two drop plates in the prior art is fixed and cannot be adjusted due to the different aeration and reoxygenation requirements of different water qualities, making it difficult to adjust according to different water qualities and resulting in poor applicability.
