[0002] Aeration is a commonly used technology in sewage treatment. It specifically refers to the process of forcibly transferring oxygen from the air into the liquid. Its purpose is to obtain sufficient dissolved oxygen and simultaneously achieve the effects of increasing oxygen, preventing sedimentation, and accelerating the degradation of organic matter.

[0019] like Figure 1-2 and Figure 9-10 As shown:

[0020] It includes a fixed rod 106, which is slidably connected to a connecting frame 105, and a connecting plate 101 is slidably connected to the connecting frame 105. A plurality of air inlets 102 are provided on the connecting plate 101, and a plurality of aeration tubes 103 are fixedly connected to the lower side of the connecting plate 101, each aeration tube 103 is provided with a plurality of air holes, and each aeration tube 103 is fixedly connected to a knocking plate 104, and the plurality of knocking plates 104 can all contact the connecting frame 105. A plurality of hoses for letting in air are respectively connected to the plurality of air inlets 102, a first motor is fixedly connected to the fixed rod 106, and a first screw is fixedly connected to the output shaft of the first motor, and the first screw is threadedly connected to the connecting plate 101, and the interior of the connecting plate 101 is a hollow structure.

[0021] The connecting plate 101 is placed in the sewage treatment tank. When sewage treatment is required and sewage is added to the sewage treatment tank, multiple hoses can be used to continuously introduce air into the multiple air inlets 102. After the air enters the interior of the connecting plate 101 through the multiple air inlets 102, it will naturally be discharged through the air holes on the multiple aeration pipes 103 and then quickly enter the sewage, thereby achieving the effects of increasing oxygen, preventing sedimentation, and accelerating the degradation of organic matter, thereby completing the aeration work;

[0022] In the process of introducing air into the sewage through the air holes on the multiple aeration pipes 103, the connecting frame 105 can be operated to slide back and forth on the fixed rod 106, thereby completing a full aeration operation in the sewage treatment tank and improving the aeration treatment effect. At the same time, in the process of operating the connecting frame 105 to slide on the fixed rod 106, the connecting plate 101 can be operated to slide back and forth up and down on the connecting frame 105, so that the multiple knocking pieces 104 on the connecting plate 101 collide with the connecting frame 105 multiple times, thereby enabling the connecting plate 101 to slide up and down during the aeration process and to vibrate slightly due to the collision, so that impurities in the sewage are less likely to adhere to the multiple air holes, thereby ensuring that the multiple air holes are always unobstructed and maintaining a full aeration effect for a long time.

[0023] The provision of multiple air inlets 102 enables multiple hoses to simultaneously undertake the task of introducing air during the process of introducing air into the connecting plate 101, thereby avoiding the situation where only a single air input structure fails, thereby affecting the correct performance of subsequent aeration operations. At the same time, it can also avoid the situation where the connecting plate 101 is suddenly unable to discharge air to the outside, thereby causing a large amount of impurities in the sewage to adhere to the air holes, thereby causing inconvenience to subsequent operation and maintenance operations.

[0024] like Figure 1 、 Figure 4 and Figure 9-10 As shown:

[0025] It also includes a fixed ring 304, on which a rotating rod 301 is rotatably connected, and a plurality of transmission arc blocks 302 are fixedly connected to the rotating rod 301, a cylindrical rod 107 is fixedly connected to the connecting plate 101, a first compression spring is fixedly connected between the connecting frame 105 and the connecting plate 101, and a second motor that can drive the rotating rod 301 to rotate is fixedly connected to the fixed ring 304.

[0026] When the connecting frame 105 is operated to slide on the fixed rod 106, the multiple sliding seats 201 on the connecting plate 101 will always contact the rotating rod 301. When the sliding seat 201 moves to contact one of the multiple transmission arc blocks 302, as the connecting frame 105 continues to slide, the transmission arc block 302 gradually pushes the sliding seat 201, thereby causing the connecting plate 101 to slide upward on the connecting frame 105, overcoming the elastic force of the first compression spring. When the sliding seat 201 is separated from the transmission arc block 302, the connecting plate 101 is quickly reset downward by the elastic force of the first compression spring, thereby causing the multiple knocking pieces 104 to perform a force-accumulating knocking operation with the lower side of the connecting frame 105, thereby causing the connecting plate 101 to vibrate slightly as a whole, shaking off impurities that may have been stuck to the multiple air holes. As the connecting frame 105 continues to slide, the connecting plate 101 will slide back and forth on the connecting frame 105, thereby completing the effect of avoiding clogging and adhesion of impurities in the sewage.

[0027] When the connecting frame 105 slides to the right to the farthest distance and needs to be slid back and reset, the rotating rod 301 can be operated to rotate, thereby staggering the transmission arc block 302 and the sliding seat 201, providing convenience for the reverse sliding reset operation of the connecting frame 105.

[0028] like Figure 4 As shown:

[0029] The heights of the transmission arc blocks 302 gradually increase from left to right.

[0030] The different height settings of the multiple transmission arc blocks 302 can enable different degrees of force-accumulating collision operations to occur between the connecting plate 101 and the connecting frame 105, so that the knocking force can be changed, and further facilitate the shaking off of impurities that may be adhered to multiple air holes, thereby improving the effect of avoiding blockage.

[0031] like Figure 4-10 As shown:

[0032] It also includes a vertical rod 401, which is fixed with a sliding rail 402, and a moving part 501 is slidably connected to the sliding rail 402, and a marking groove 504 is fixed to the moving part 501, and a rotating plate 602 is connected to the vertical rod 401, and the rotating plate 602 can rotate about a virtual axis, and a marking plate 603 is fixed to the rotating plate 602, and a marking protrusion 604 is fixed to the marking plate 603, and the rotating plate 602 can contact the marking groove 504, and a second compression spring is fixed between the sliding rail 402 and the moving part 501, and an arc panel 503 is fixed to the moving part 501, and a toggle rod 303 is connected to the rotating rod 301, and the toggle rod 303 can contact the arc panel 503.

[0033] Whenever the operating lever 301 rotates on the fixed ring 304, thereby causing the multiple transmission arc blocks 302 to stagger with the sliding seat 201, the toggle lever 303 will rotate synchronously with the rotating lever 301. During the rotation of the toggle lever 303, the toggle lever 303 can naturally contact the arc plate 503, thereby applying a thrust to the arc plate 503, so that the moving part 501 overcomes the elastic force of the second compression spring and slides on the slide rail 402. During this process, the marking groove 504 can contact the rotating plate 602, thereby driving the rotating plate 602 to rotate, so that the marking plate 603 on the rotating plate 602 follows The rotating plate 602 rotates synchronously, thereby changing the position of the marking protrusion 604, and then recording the number of rotations of the toggle rod 303, thereby recording the number of reciprocating slides of the connecting frame 105, that is, it can reliably assist in displaying the processing time without the participation of the electronic program. Even if the processing time display structure of the electronic program fails, the staff can still quickly and roughly know the aeration operation time according to the position of the marking protrusion 604 after arriving at the equipment, which brings convenience to the staff's actual operation.

[0034] like Figure 5-6 and Figure 9 As shown:

[0035] It also includes a matching rod 502 rotatably connected to the moving part 501, a slider 601 is slidably connected to the vertical rod 401, a third compression spring is fixed between the slider 601 and the vertical rod 401, a torsion spring is fixed between the matching rod 502 and the moving part 501, an electromagnetic block capable of adsorbing the matching rod 502 is fixed to the moving part 501, a cylinder is fixed to the slider 601, and the rotating plate 602 is rotatably connected inside the cylinder.

[0036] When the cam 303 is in the process of being rotated, the lever 303 is pressed against the lower side of the cylinder on the slider 601 by the torsion force of the torsion spring. When the cam 303 is in the process of being rotated, the lever 303 is pressed against the lower side of the cylinder on the slider 601 by the torsion force of the torsion spring. When the cam 303 is in the process of being rotated, the lever 303 is pressed against the lower side of the cylinder on the slider 601 by the torsion force of the torsion spring. When the cam 303 is in the process of being rotated, the lever 303 is pressed against the lower side of the cylinder on the slider 601.

[0037] After the moving part 501 is completely reset, the adsorption force of the electromagnetic block is removed to reset the matching rod 502 and the slider 601, so as to facilitate subsequent transmission work.

[0038] like Figure 6 As shown:

[0039] The device further comprises a reference plate 403 fixedly connected to the vertical rod 401 , and a plurality of reference slots 404 are formed on the reference plate 403 .

[0040] The provision of the reference plate 403 and the plurality of reference slots 404 can facilitate the staff to make an auxiliary reference to the processing time represented by the position of the marking protrusion 604, thereby further facilitating a reliable display of the processing time.

[0041] like Figure 4 、 Figure 6 and Figure 8-9 As shown:

[0042] It also includes a plurality of 505 opened on the arc panel 503, the toggle rod 303 is slidably connected to the rotating rod 301, and the rotating rod 301 is fixed with a first electric push rod that can push the toggle rod 303 to slide.

[0043] During the process of displaying the processing time, if the processing time is long and the processing time cannot be fully displayed by rotating the rotating plate 602 one circle, the toggle rod 303 can be operated to slide on the rotating rod 301 after the reference plate 403 rotates one circle, thereby moving the toggle rod 303 to face different 505 positions, so that the staff can further judge the processing time according to the position of the toggle rod 303 and expand the processing time display range.

[0044] like Figure 1 、 Figure 3 and Figure 9 As shown:

[0045] It also includes a sliding seat 201 slidably connected to the cylindrical rod 107, a sealing portion 202 is fixed to the sliding seat 201, and a second electric push rod is fixed to the cylindrical rod 107 to drive the sliding seat 201 to slide. The cylindrical rod 107 is a hollow structure.

[0046] The staff can regularly operate the sliding seat 201 to slide, so that the blocking part 202 on the sliding seat 201 is moved away from the original blocking position of the cylindrical rod 107, so that the air inside the connecting plate 101 can be partially discharged from the cylindrical rod 107, so that the staff can detect whether the air is normally entering the connecting plate 101 through the cylindrical rod 107, and thus can perform a more intuitive detection of the aeration situation, which brings convenience to actual use.

[0047] like Figure 3 As shown:

[0048] It also includes a wind wheel 203 rotatably connected to the blocking portion 202 .

[0049] After the sliding seat 201 is moved away and part of the gas is discharged from the cylindrical rod 107, the discharged gas can blow the wind wheel 203 to rotate on the blocking portion 202, thereby further facilitating the detection of the aeration condition.

[0050] like Figure 9-10 As shown:

[0051] The fixing rod 106 and the fixing ring 304 are both provided with a plurality of threaded holes.

[0052] Bolts are screwed into the multiple fixing threaded holes to fix the fixing rods 106 and 306 in appropriate positions, thereby completing the fixing effect of the device.
