Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment devices, and specifically relates to an air flotation sewage treatment device. Background Technology

[0002] Air flotation wastewater treatment devices are highly efficient equipment that achieves wastewater purification based on the core principle of air flotation separation. They are widely applicable to wastewater treatment scenarios containing impurities such as oil, suspended solids, and colloids.

[0003] For example, Chinese patent CN222064180U discloses an air flotation wastewater treatment device, which includes a base, casters, a treatment box, and an air pump. The casters are symmetrically and rotatably connected to the lower left and right sides of the base. The treatment box is connected to the upper side of the base, and the air pump is connected to the upper left side of the base.

[0004] While the aforementioned patents have solved the problem that existing devices struggle to clean impurities from the skimmer plate during the skimming process, and that repeated use of the skimmer plate can cause some impurities to fall back to the water surface, affecting skimming efficiency, existing flotation wastewater treatment equipment still has some shortcomings that need improvement. During long-term operation, the skimmer plate is prone to edge wear and surface damage due to continuous friction with scum and contact with corrosive substances in the wastewater. Once the skimmer plate is worn to the point that it affects the skimming effect, the machine must be stopped immediately for disassembly and replacement, which is very troublesome.

[0012] In summary, the present invention has the following main advantages:

[0013] First, this utility model effectively solves the problem of having to stop immediately to replace worn scrapers in traditional devices by setting a sliding first scraper and a second scraper in the movable seat and using a second power component to switch between the two scrapers. When one scraper is worn at the edge or damaged on the surface due to long-term friction with scum or contact with corrosive substances in sewage, affecting the scraping effect, there is no need to interrupt the sewage treatment process. The second power component can drive the transmission gear and transmission rack to move the unworn scraper to the working position to continue the scraping operation. The other worn scraper can be disassembled and replaced during the standby period of the device, which extends the service life of the scraping structure and ensures the continuity of sewage purification.

[0014] Secondly, this utility model, by setting a guide component, through the cooperation of guide groove, guide block and guide rod, ensures that the first scraper and the second scraper move smoothly during switching and operation, and avoids the scraping effect being affected by the scraper offset.

[0020] Example

[0021] refer to Figures 1 to 4 In this embodiment of the air flotation wastewater treatment device, when it is necessary to switch scrapers, the second motor 72 inside the frame 71 is started. The output end of the second motor 72 drives the transmission gear 73 to rotate. The two sides of the transmission gear 73 respectively mesh with two transmission racks 74, thereby driving the two transmission racks 74 to move in opposite directions. One side of the transmission rack 74 is fixedly connected to the linkage rod 75. The linkage rod 75 is connected to the first scraper 5 and the second scraper 6 by bolts. Therefore, when the transmission rack 74 moves, it will drive the corresponding scraper to slide in the through hole 9 of the moving seat 3. The two racks correspond to the first scraper 5 and the second scraper 6 respectively, which can realize the independent control of the scrapers. The switching response speed is fast, ensuring that the spare scraper can be used immediately when the scraper is worn, without affecting the continuity of the sludge scraping work.

[0022] refer to Figure 4The guide assembly 8 includes a support plate 81, which is fixedly connected to the movable seat 3 on both sides of the transmission gear 73. A guide groove 82 is formed inside the support plate 81, and a guide block 84 is slidably connected inside the guide groove 82. One side of the guide block 84 is fixedly connected to one side of the transmission rack 74. A guide rod 83 is fixedly connected inside the guide groove 82, and the guide block 84 is slidably connected to the guide rod 83. By setting the guide assembly 8, during the movement of the transmission rack 74 driven by the second power assembly 7, the guide block 84 on one side of the transmission rack 74 slides synchronously in the guide groove 82 inside the support plate 81. Simultaneously, the guide block 84 is fitted onto the guide rod 83 within the guide groove 82 and moves axially along the guide rod 83. When the transmission rack 74 drives the scraper to extend or retract, the guide block 84 always slides along the trajectory of the guide groove 82 and the guide rod 83, thus limiting the movement direction of the transmission rack 74 and effectively preventing the transmission rack 74 from deviating or wobbling during movement.

[0023] refer to Figure 1 A collection box 11 is placed on one side of the processing box 1, and the collection box 11 is located below the discharge hole 10. When the scraper pushes the scum in the processing box 1 toward the discharge hole 10, the scum is discharged from the discharge hole 10 under the pushing force of the scraper. Since the collection box 11 is placed on one side of the processing box 1 and located below the discharge hole 10, the discharged scum will fall directly into the collection box 11.

[0024] Operating principle and advantages: Wastewater is introduced into treatment tank 1, and the air pump 12 on the base 2 is started. The air pump 12 draws dissolved gas from the dissolved gas bottle 13 through the pipeline and sends it into treatment tank 1, causing impurities in the wastewater to combine with the dissolved gas to form scum that floats to the surface. Then, the first motor 42 drives the small gear 43 to rotate, which in turn drives the lead screw 45 to rotate through meshing with the large gear 44. The screw block 46 slides along the lead screw 45 under the limit of the fixed seat 41, thereby driving the moving seat 3 and the extended first scraper 5 to move along treatment tank 1, pushing the scum towards the discharge. When the first scraper 5 wears out, the second motor 72 drives the transmission gear 73 to rotate. Through the reverse movement of the double rack, the first scraper 5 is retracted and the second scraper 6 is extended, so that scraping can continue without stopping the machine. During this process, the guide assembly 8 slides along the guide groove 82 and the guide rod 83 through the guide block 84, which limits the offset of the transmission rack 74, ensures the stability of scraper switching and movement, avoids scraper collision and wear, and extends service life. Finally, the scum is discharged through the discharge hole 10 and falls into the collection box 11 below.
