Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for cleaning and collecting scum from the surface of oxidation ditch ponds. Background Technology
[0002] An oxidation ditch is an activated sludge treatment system, named for its closed, ring-shaped structure. The oxidation ditch process belongs to the extended aeration activated sludge method, and there are various types of oxidation ditches, including the three-ditch oxidation ditch and the Orbal oxidation ditch.
[0003] Currently, oxidation ditches mostly use baffles that are lower than the surface of the pool to block scum, while the water in the pool is discharged through drainage holes located below the scum. In order to avoid scum accumulation and blockage, it needs to be cleaned. However, the cleaning of scum on the surface of existing oxidation ditches is very cumbersome and costly, which brings inconvenience to manufacturers. Therefore, we propose an oxidation ditch scum cleaning and collection device. Utility Model Content

[0013] 1. This utility model, through the arrangement of guide vanes, a slag collection and discharge seat guide float, a fixed sleeve, a rotating rod, and a floating sleeve, allows the wastewater to enter the main body of the oxidation ditch through the liquid guide pipe. The water impacts the guide vanes, which in turn drive the floating sleeve, the guide float, and the rotating rod to rotate. When the limiting slider slides inside the guide groove, and with the assistance of the floating sleeve, the guide float can always float on the surface of the pool. The guide float, which floats on the surface of the pool and rotates in a uniform direction, can guide the floating slag on the surface of the pool toward the slag collection and discharge seat. When the drive motor of the slag collection and discharge seat is working, and with the assistance of the slag discharge hopper, the slag can be quickly cleaned.

[0025] Example 1
[0026] Please see Figures 1-4 As shown, this utility model provides a technical solution: a device for cleaning and collecting scum on the surface of an oxidation ditch, comprising an oxidation ditch body 1 with a liquid guide pipe 2 installed at the bottom center. Multiple equidistantly distributed support sleeves 3 are fixedly connected to the left end of the bottom inner side of the oxidation ditch body 1. A rotating rod 18 is movably connected to the center of the top of each support sleeve 3 via a bearing. Guide grooves 16 are provided on both the left and right sides of the upper end of the rotating rod 18. A fixed sleeve 14 is slidably connected to the upper end of the outer surface of the rotating rod 18. Sliding elements within the guide grooves 16 are fixedly connected to both the left and right sides of the lower end of the inner cavity of the fixed sleeve 14. The limiting slider 15, the top of the fixed sleeve 14 is fixedly connected to the guide float 6, the bottom middle of the guide float 6 is fixedly connected to the float sleeve 13 which is sleeved on the outside of the fixed sleeve 14, the bottom of the guide float 6 and the outer surface of the float sleeve 13 are fixedly connected to the guide vanes 9, the number of guide vanes 9 is multiple, and the included angle between two adjacent guide vanes 9 is equal, the top left end of the oxidation ditch tank body 1 is fixedly installed with a slag collection and discharge seat 5, the front of the slag collection and discharge seat 5 is fixedly installed with a drive motor 12, and the upper left end of the slag collection and discharge seat 5 is provided with a slag discharge hopper 11.
[0027] This technical solution, through the arrangement of guide vanes 9, slag collection seat 5, guide float 6, fixed sleeve 14, rotating rod 18, and float sleeve 13, allows the wastewater to be treated to enter the main body 1 of the oxidation ditch tank via the liquid guide pipe 2. The water can impact the guide vanes 9, which in turn drive the float sleeve 13, guide float 6, and rotating rod 18 to rotate. When the limiting slider 15 slides inside the guide groove 16, and with the assistance of the float sleeve 13, the guide float 6 can always float on the surface of the tank. The guide float 6, which floats on the surface of the tank and can rotate in a uniform direction, can guide the floating slag on the surface of the tank toward the slag collection seat 5. When the drive motor 12 of the slag collection seat 5 is working, and with the assistance of the slag discharge hopper 11, the slag can be cleaned quickly. This solution is convenient to use and has low energy consumption.
[0028] Example 2
[0029] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a drive impeller 17 is fixedly connected to the outer surface of the rotating rod 18 located inside the support sleeve 3. A liquid passage hole 20 is opened at the upper end of the right side of the support sleeve 3. A nozzle 10 is connected to the lower end of the front side of the support sleeve 3. A nozzle 8 is fixedly installed at the end of the nozzle 10 away from the support sleeve 3.
[0030] This technical solution, through the arrangement of the drive impeller 17, support sleeve 3, liquid passage hole 20, nozzle 10 and nozzle 8, enables the drive impeller 17 to rotate within the support sleeve 3 when the rotating rod 18 rotates. With the assistance of the liquid passage hole 20, the rotating drive impeller 17 can draw water without scum from the main body 1 of the oxidation ditch into the support sleeve 3 through the liquid passage hole 20, and after pressurization, spray it outward through the nozzle 10 and nozzle 8, thereby washing away the activated sludge adsorbed on the surface of floating matter such as scum, facilitating the collection of scum.
[0031] Example 3
[0032] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a fixing plate 4 is fixedly connected to the left end of the top of the oxidation ditch tank body 1. Multiple generators 19 corresponding to the support sleeve 3 are fixedly installed on the top of the fixing plate 4. The output end of the generator 19 is fixedly connected to the middle end of the top of the guide float 6 through the floating sleeve. A protective cover 7 is fixedly connected between the outer side of the generator 19 and the top of the fixing plate 4. Multiple inclined heat dissipation holes are provided on the outer surface of the protective cover 7.
[0033] This technical solution: By setting up the generator 19, the fixed plate 4, and the protective cover 7, the generator 19 can be driven to rotate via the floating sleeve when the guide float 6 rotates, enabling the device to generate electricity. With the assistance of an external battery and transformer, it provides power support for the operation of the drive motor 12, thereby avoiding the use of additional power and further reducing the operating cost of the device. (It should be noted that the floating sleeve is an existing product, which is a cylindrical tube with a guide groove on the inner side. The guide groove can cooperate with the output end of the generator 19 to prevent the generator 19 from affecting the movement of the guide float 6 when it floats up and down on the pool surface.)
