Description

Technical Field

[0001] This utility model relates to the field of aeration equipment technology, specifically to an aerator unblocking device. Background Technology

[0002] Aerators are key equipment in wastewater treatment systems, mainly used to deliver air into wastewater, thereby promoting the degradation of organic pollutants in the wastewater.

[0003] Based on their usage, aerators can be classified into surface aerators and underwater aerators. Surface aerators are installed on the water surface and use mechanical rotation to introduce air into the water. Underwater aerators are devices installed underwater for aeration. Examples include tubular aerators and disc aerators.

[0004] Wastewater contains a large amount of suspended solids, colloids, grease and other impurities. These impurities tend to accumulate on the surface of underwater aerators, causing blockage of the micropores on the surface of the underwater aerators and affecting aeration operations.

[0005] Currently, cleaning and unclogging methods include chemical cleaning and physical cleaning. Physical cleaning includes high-pressure water gun cleaning and manual cleaning. High-pressure water gun cleaning wastes cleaning water resources. Manual cleaning requires manual use of brushes or fine cloths to wipe the surface of the underwater aerator to remove deposited impurities, unclog the aerator, and restore its aeration performance. This manual cleaning operation increases labor intensity and reduces unclogging efficiency.

[0006] Therefore, how to avoid wasting clean water resources, reduce the intensity of manual labor, and improve dredging efficiency are the technical problems that need to be solved. Utility Model Content

[0007] To address the aforementioned shortcomings of existing technologies, this invention proposes an aerator unblocking device that can avoid wasting clean water resources, reduce manual labor intensity, and improve unblocking efficiency.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An aerator unblocking device includes a transverse beam, a first wave groove on one side of the beam and a second wave groove on the other side of the beam, the waveforms of the first wave groove and the second wave groove being parallel to each other, a movable seat being fitted on the beam, the movable seat being slidably engaged with the first wave groove and the second wave groove, a drive seat being slidably connected to the movable seat along the longitudinal direction, a power mechanism for driving the drive seat to move laterally on the beam, a vertical beam being provided at the bottom of the movable seat, and a brush being provided at the bottom of the vertical beam.

[0010] Furthermore, the bottom of the drive seat is provided with a dovetail groove, and the top of the movable seat is provided with a slide rail, which extends longitudinally and slides in cooperation with the dovetail groove.

[0011] Furthermore, the power mechanism includes a drive device, a driving pulley, a driven pulley, and a transmission belt. The first end of the crossbeam is rotatably connected to the driving pulley, and the first end of the crossbeam is also provided with a drive device for driving the driving pulley to rotate. The second end of the crossbeam is rotatably connected to the driven pulley. The driving pulley is driven by the driven pulley through the transmission belt, and the transmission belt is connected to the drive seat.

[0012] Furthermore, the drive base includes a drive base plate and a drive top plate. The bottom surface of the drive base plate is provided with the dovetail groove, and the top surface of the drive base plate is provided with a drive screw. The drive screw passes upward through the drive top plate, and a drive nut is threaded onto the drive screw. The drive nut and the drive base plate clamp the drive top plate, and the drive top plate and the drive base plate clamp the transmission belt.

[0013] Furthermore, the movable seat includes a movable base plate, a movable top plate, a first cylinder and a second cylinder. The bottom of the movable base plate is provided with the vertical beam, and the top surface of the movable base plate is provided with the first cylinder and the second cylinder. The top of the first cylinder and the top of the second cylinder are both connected to the movable top plate. The first cylinder is slidably engaged with the first wave groove, and the second cylinder is slidably engaged with the second wave groove. The movable top plate is provided with the slide rail.

[0014] Furthermore, the vertical beam includes a first vertical rod and a second vertical rod, the top of the first vertical rod is connected to the bottom of the movable seat, the bottom of the first vertical rod is detachably connected to the top of the second vertical rod, and the bottom of the second vertical rod is connected to the brush.

[0015] Furthermore, the bottom of the first vertical rod is provided with a first mounting plate, the top of the second vertical rod is provided with a second mounting plate, the second mounting plate is provided with a mounting screw, the mounting screw passes upward through the first mounting plate, and a mounting nut is threaded onto the mounting screw, the mounting nut and the second mounting plate clamp the first mounting plate.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this invention, the power mechanism drives the brush to move laterally, while the first and second wave grooves guide the brush to reciprocate longitudinally. This allows the brush to brush the surface of the disc aerator both laterally and longitudinally, cleaning the dirt covering the surface and unblocking the pores. This eliminates the need for manual cleaning, reducing labor intensity and improving cleaning efficiency. Furthermore, this invention eliminates the need for high-pressure rinsing with clean water, reducing water waste.

[0018] 2. When cleaning the surface of the disc aerator, this utility model does not require emptying the sewage in the sewage tank, which will not delay sewage treatment and improves the convenience of use.

[0019] 3. Because the brush is located at the bottom of the second vertical rod, the brush will not be blocked by the air supply pipe when it brushes over the surface of the disc aerator, and will not hinder the brush's cleaning action on the disc aerator, further improving the ease of use.

[0020] 4. Because the first vertical rod and the second vertical rod are detachably connected, the brushes at the bottom of the second vertical rod can be replaced, making it convenient to maintain the unblocking device of this utility model.

[0021] 5. Because the brush is lifted out of the sewage tank by raising the second vertical rod, there is no need to empty the sewage tank, which will not delay sewage treatment and improves maintenance convenience. Attached Figure Description

[0042] Example:

[0043] See Figures 1 to 10 An aerator unblocking device includes a crossbeam 1, a movable seat, a drive seat, a power mechanism, a vertical beam, and a brush 7.

[0044] The crossbeam 1 extends laterally. When using the unblocking device of this embodiment, see [reference needed]. Figure 9 Both ends of the crossbeam 1 (the first end and the second end, respectively) need to be fixedly installed on the top of the sewage tank wall 2. See [link / reference]. Figure 7 and Figure 8 A first wave groove 11 is provided on one side of the crossbeam 1, and a second wave groove 12 is provided on the other side of the crossbeam 1.

[0045] See Figure 8The waveform of the first wave groove 11 is set parallel to the waveform of the second wave groove 12. That is, the convex position of the first wave groove 11 corresponds to the concave position of the second wave groove 12, and the concave position of the first wave groove 11 corresponds to the convex position of the second wave groove 12, so that the longitudinal distance L1 of the first wave groove 11 and the second wave groove 12 is the same.

[0046] See Figure 5 and Figure 6 The movable seat includes a movable base plate 31, a movable top plate 32, a first cylinder 33, and a second cylinder 34. The first cylinder 33 and the second cylinder 34 are welded and fixed to the top surface of the movable base plate 31. The tops of both the first cylinder 33 and the second cylinder 34 are welded and fixed to the movable top plate 32. When the movable seat is fitted onto the crossbeam 1, the top surface of the movable base plate 31 slides into the bottom surface of the crossbeam 1, the bottom surface of the movable top plate 32 slides into the top surface of the crossbeam 1, the first cylinder 33 slides into the first wave groove 11, and the second cylinder 34 slides into the second wave groove 12.

[0047] See Figure 5 and Figure 6 The drive base is located above the movable base. The drive base includes a drive base plate 41, a drive top plate 42, a drive screw 43, and a drive nut 44. The drive screw 43 is welded to the top surface of the drive base plate 41. The drive top plate 42 has a drive through hole, through which the drive screw 43 extends upwards. The drive nut 44 is threaded onto the drive screw 43. Tightening the drive nut 44 downwards clamps the drive nut 44 and the drive base plate 41 together with the drive top plate 42.

[0048] The bottom surface of the drive base plate 41 is provided with a dovetail groove 411, and the top surface of the movable top plate 32 is welded and fixed with a slide rail 321. The slide rail 321 extends longitudinally and slides in cooperation with the dovetail groove 411 longitudinally.

[0049] The power mechanism drives the drive unit to move laterally. The power mechanism includes a drive unit, a driving pulley 52, a driven pulley 53, and a transmission belt 54. See also... Figure 7 The drive device uses a servo motor 51, which is fixedly mounted at the first end of the crossbeam 1. The axle of the drive pulley 52 is rotatably mounted at the first end of the crossbeam 1 via bearings. The output end of the servo motor 51 is fixedly connected to the axle of the drive pulley 52. ​​The axle of the driven pulley 53 is rotatably mounted at the second end of the crossbeam 1 via bearings. See also... Figures 1 to 4 The drive belt 54 is wound around the outer circumference of the driving pulley 52 and the driven pulley 53, and the driving pulley 52 is driven by the drive belt 54 to drive the driven pulley 53. (See also...) Figure 5 and Figure 6 The transmission belt 54 is sandwiched between the drive top plate 42 and the drive bottom plate 41 of the drive seat. When the transmission belt 54 rotates, it drives the drive seat to move together.

[0050] See Figure 5 and Figure 6 The vertical beam includes a first vertical rod 61 and a second vertical rod 62. The top of the first vertical rod 61 is welded and fixed to the bottom of the movable base plate 31, and a first mounting plate 611 is welded and fixed to the bottom of the first vertical rod 61. The first mounting plate 611 has a mounting through hole. The top of the second vertical rod 62 is welded and fixed to a second mounting plate 621, and a mounting screw 622 is welded and fixed to the second mounting plate 621. The mounting screw 622 extends upward through the mounting through hole, and a mounting nut 623 is threaded onto the mounting screw 622. The mounting nut 623 and the second mounting plate 621 clamp the first mounting plate 611.

[0051] See Figure 5 and Figure 6 The brush 7 is welded and fixed to the bottom of the second vertical rod 62.

[0052] The working principle of the aerator unblocking device in this embodiment is as follows:

[0053] (1) See Figure 9 and Figure 10 The principle is as follows when cleaning the multiple disc aerators 9 on the gas transmission pipeline 8:

[0054] The servo motor 51 is started, which drives the drive pulley 52 to rotate. The drive pulley 52 drives the driven pulley 53 to rotate via the transmission belt 54. During this process, the transmission belt 54 drives the drive seat to move laterally, the drive seat drives the movable seat to move laterally, the movable seat drives the vertical beam to move laterally, the vertical beam drives the brush 7 to move laterally, and the brush 7 brushes laterally across the surface of the disc aerator 9.

[0055] Because the first wave groove 11 and the second wave groove 12 on the crossbeam 1 are arranged in parallel, and the movable seat slides in conjunction with the first wave groove 11 and the second wave groove 12, the movable seat moves longitudinally and reciprocally under the guidance of the first wave groove 11 and the second wave groove 12 during the lateral movement. The movable seat drives the vertical beam, and the vertical beam drives the brush 7 to longitudinally and reciprocally brush the surface of the disc aerator 9. During the longitudinal reciprocating movement of the movable seat, the movable seat slides relative to the drive seat in the longitudinal direction.

[0056] In summary, the brush 7 moves both laterally and longitudinally, allowing it to brush the surface of the disc aerator 9 both horizontally and vertically. This cleans the dirt covering the surface of the disc aerator 9 and unclogs the air pores, eliminating the need for manual cleaning, thus reducing labor intensity and improving cleaning efficiency. Furthermore, the cleaning device in this embodiment does not require high-pressure washing with clean water, reducing waste of clean water resources.

[0057] In this embodiment, when cleaning the surface of the disc aerator 9, there is no need to empty the sewage in the sewage tank 2, which will not delay sewage treatment and improves the convenience of use.

[0058] Because the brush 7 is located at the bottom of the second vertical rod 62, when the brush 7 brushes over the surface of the disc aerator 9, the brush 7 will not be blocked by the air supply pipe 8, and will not hinder the cleaning action of the brush 7 on the disc aerator 9, further improving the ease of use.

[0059] (2) When it is necessary to replace brush 7, the principle is as follows:

[0060] First, the worker unscrews the mounting nut 623 from the mounting screw 622; then, the worker lowers the second mounting plate 621, causing the mounting screw 622 on the top surface of the second mounting plate 621 to be removed from the mounting through hole on the first mounting plate 611; next, the worker lifts the first mounting plate 611 out of the sewage tank 2, which in turn lifts the second vertical rod 62 out of the sewage tank 2, and the second vertical rod 62 lifts the brush 7 out of the sewage tank 2; finally, the new second vertical rod 62 is assembled with the first vertical rod 61, and the new brush 7 at the bottom of the new second vertical rod 62 re-enters the sewage tank 2, thus completing the replacement of the brush 7.

[0061] Through the above process, the brush 7 can be replaced, which facilitates the maintenance of the unblocking device in this embodiment.

[0062] Furthermore, since the brush 7 is lifted out of the sewage tank 2 by raising the second vertical rod 62, there is no need to empty the sewage tank 2, which will not delay sewage treatment and improves maintenance convenience.

[0063] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
