Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater air flotation and scum defoaming machine. Background Technology

[0002] In wastewater treatment processes, air flotation or chemical coagulation air flotation is a commonly used technology. However, these technologies often face a problem in practical applications: a layer of scum containing a large number of tiny air bubbles forms above the water layer. These air bubbles make it difficult for the scum to sink, thus affecting the subsequent treatment process. In order to improve this phenomenon, it is particularly important to design a wastewater air flotation scum defoamer.

[0003] A wastewater flotation and scum defoamer, as described in reference announcement number CN203229400U, includes a motor connected to a rotating rod via a reducer and coupling. The rotating rod is inverted "T" shape, with multiple fixed vertical shafts distributed on its horizontal bar. Each fixed vertical shaft has blades that can rotate around it. These blades can release air bubbles from the scum in both horizontal and vertical directions, significantly accelerating the breaking and settling of the scum and shortening the solid-liquid separation time. Generally, depending on the thickness of the scum layer, breaking bubbles can be achieved within 2-10 seconds, while simultaneously achieving full coverage of the scum layer. This can meet the defoaming requirements of large volumes of water. However, while this defoamer can be widely used, it is generally difficult to adjust the height of the defoaming components, making it challenging to defoam scum at a specific liquid surface, thus presenting certain limitations. Utility Model Content

[0004] The purpose of this utility model is to provide a wastewater flotation and scum defoaming machine to solve the problem mentioned in the background art that although the defoaming machine can be applied well, it is usually inconvenient to adjust the height of the defoaming components, which makes it difficult to perform defoaming operations on bubbles and scum on a specified liquid surface, thus having certain limitations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewage flotation and scum defoaming machine, comprising a base, a push handle on one side of the top of the base, a stand on the other side of the top of the base, a transmission box at the top of the stand, a first belt drive mechanism inside the transmission box, a first motor mounted on one side of the bottom of the transmission box, the top of the first motor connected to one side of the bottom of the first belt drive mechanism, a threaded rod on the other side of the bottom of the first belt drive mechanism, the bottom end of the threaded rod extending to the outside of the transmission box, and two guides on the outer wall of the stand on one side of the threaded rod via a bracket. The rod has a nut seat threaded onto its outer wall. The nut seat is movably connected to the guide rod. A transmission frame is provided at the top of the nut seat. A drive gear is rotatably mounted on one side of the bottom of the transmission frame. A driven gear is rotatably mounted on the bottom of the transmission frame on the side of the drive gear. The driven gear meshes with the drive gear. A second belt drive mechanism is provided at the top of the driven gear. A second linkage shaft is provided at the bottom of the second belt drive mechanism. A control frame is provided on the inner wall of the upper end of the push handle. A control box is installed on the outer wall of the control frame. The output terminal of the microcontroller inside the control box is electrically connected to the input terminal of the first motor.

[0006] Preferably, two rear rollers are installed on one side of the bottom end of the base, and two front rollers are installed on the other side of the bottom end of the base. The arrangement of the front and rear rollers is to facilitate the conveying and transfer of the defoaming machine.

[0007] Preferably, a dual-axis motor is provided at the bottom of the base between the front rollers. The input end of the dual-axis motor is electrically connected to the output end of the microcontroller inside the control box. Both ends of the dual-axis motor are connected to the inner wall of the front rollers. The dual-axis motor is provided to drive the front rollers to rotate.

[0008] Preferably, a second motor is installed at the top of the transmission frame. The input end of the second motor is electrically connected to the output end of the microcontroller inside the control box, and the bottom end of the second motor is connected to the top of the drive gear. The second motor is configured to drive the drive gear to rotate.

[0009] Preferably, the bottom end of the drive gear is provided with a first linkage shaft, and the bottom ends of both the first linkage shaft and the second linkage shaft extend to the outside of the transmission frame and are provided with a stirring shaft. The stirring shaft is provided to facilitate the placement of the defoaming plate.

[0010] Preferably, the bottom end of the stirring shaft is provided with a defoaming plate, and the bottom end of the defoaming plate is provided with equally spaced defoaming pipes. The defoaming pipes are provided to defoam the bubbles and scum on the surface of the sewage in the sewage treatment equipment.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the sewage flotation and scum defoaming machine can not only defoam the bubbles and scum on different liquid surfaces to improve the applicability of the defoaming machine, but also improve the defoaming efficiency of the defoaming machine when using it, and achieve the purpose of easy and quick transportation of the defoaming machine.

[0012] (1) The first belt drive mechanism is driven by the first motor to rotate the first belt drive mechanism, so that the nut seat slides on the outer wall of the threaded rod and the guide rod, thereby adjusting the height of the defoaming tube to defoam bubbles and scum on different liquid surfaces, thus improving the applicability of the defoaming machine.

[0013] (2) The second motor drives the active gear to rotate, so that the active gear drives the first linkage shaft to rotate synchronously. Because the active gear and the driven gear mesh with each other, the driven gear drives the driven gear to rotate in opposite directions, and the driven gear drives the second linkage shaft to rotate through the second belt transmission mechanism, so that the first linkage shaft and the second linkage shaft drive the two stirring shafts to rotate in opposite directions. Thus, the defoaming tubes set at the bottom of the two sets of defoaming plates can perform double-blade stirring and defoaming of the bubbles and scum on the liquid surface, thereby improving the defoaming efficiency of the defoaming machine when it is used.

[0014] (3) The front roller is driven by a dual-axis motor to rotate, so that the front roller and the rear roller drive the base to slide on the ground. The personnel hold the push handle to push and turn the defoaming machine as a whole, so as to transport the defoaming machine and achieve the purpose of easy and quick transfer of the defoaming machine.

The input end of the dual-axis motor 4 is electrically connected to the output end of the microcontroller inside the control box 7. Both ends of the dual-axis motor 4 are connected to the inner wall of the front rollers 3.

[0024] In use, the dual-axis motor 4 is used to drive the front roller 3 to rotate;

[0025] A push handle 5 is provided on one side of the top of the base 1, and a stand 8 is provided on the other side of the top of the base 1. A transmission box 9 is provided at the top of the stand 8. A first belt drive mechanism 19 is provided inside the transmission box 9. A first motor 10 is installed on one side of the bottom of the transmission box 9. The top of the first motor 10 is connected to one side of the bottom of the first belt drive mechanism 19.

[0026] A threaded rod 11 is provided on the other side of the bottom end of the first belt drive mechanism 19. The bottom end of the threaded rod 11 extends to the outside of the transmission box 9. Two guide rods 12 are provided on the outer wall of the support frame 8 on one side of the threaded rod 11 via a bracket. A nut seat 13 is threaded on the outer wall of the threaded rod 11. The nut seat 13 is movably connected to the guide rod 12. A transmission frame 14 is provided at the top of the nut seat 13. A second motor 15 is installed at the top of the transmission frame 14. The input end of the second motor 15 is electrically connected to the output end of the microcontroller inside the control box 7. The bottom end of the second motor 15 is connected to the top end of the drive gear 20.

[0027] In use, the second motor 15 is configured to drive the drive gear 20 to rotate;

[0028] A drive gear 20 is rotatably mounted on one side of the bottom of the transmission frame 14. The bottom end of the drive gear 20 is provided with a first linkage shaft 23. The bottom ends of the first linkage shaft 23 and the second linkage shaft 24 both extend to the outside of the transmission frame 14 and are provided with a stirring shaft 16.

[0029] In use, the stirring shaft 16 is set up to accommodate the defoaming plate 17; the bottom end of the stirring shaft 16 is provided with the defoaming plate 17, and the bottom end of the defoaming plate 17 is provided with equally spaced defoaming tubes 18.

[0030] When in use, the defoaming pipe 18 is installed to defoam the bubbles and scum on the surface of the sewage in the sewage treatment equipment.

[0031] A driven gear 21 is rotatably mounted on the bottom of the transmission frame 14 on one side of the driving gear 20. The driven gear 21 meshes with the driving gear 20. A second belt drive mechanism 22 is provided at the top of the driven gear 21. A second linkage shaft 24 is provided at the bottom of the second belt drive mechanism 22.

The output terminal of the microcontroller inside the control box 7 is electrically connected to the input terminal of the first motor 10.

[0032] In this embodiment, the front roller 3 is first driven to rotate by the dual-axis motor 4, causing the front roller 3 to cooperate with the rear roller 2 to drive the base 1 to slide on the ground. A person then holds the push handle 5 to push and steer the entire defoamer for transport and transfer. This allows the defoaming pipe 18 to be moved to the area above the wastewater treatment equipment. Then, the first belt drive mechanism 19 is driven by the first motor 10, causing the first belt drive mechanism 19 to rotate the threaded rod 11. This allows the nut seat 13 to slide between the threaded rod 11 and the outer wall of the guide rod 12, thus adjusting the height of the defoaming pipe 18 to accommodate bubbles at different liquid levels. The scum undergoes defoaming, and finally, the second motor 15 drives the drive gear 20 to rotate, causing the drive gear 20 to drive the first linkage shaft 23 to rotate synchronously. Because the drive gear 20 and the driven gear 21 mesh with each other, the driven gear 21 drives the driven gear 21 to rotate in opposite directions, and the driven gear 21 drives the second linkage shaft 24 to rotate via the second belt transmission mechanism 22. This causes the first linkage shaft 23 and the second linkage shaft 24 to drive the two stirring shafts 16 to rotate in opposite directions. Thus, the defoaming pipes 18 set at the bottom of the two sets of defoaming plates 17 can perform double-blade stirring and defoaming on the surface of the sewage treatment equipment, thereby completing the use of the defoaming machine.
