Description

Technical Field

[0001] This application relates to the field of wetland filler treatment technology, and in particular to a cleaning device for agricultural waste wetland filler. Background Technology

[0002] Constructed wetland wastewater treatment systems are generally divided into surface flow wetlands and subsurface flow wetlands. They are facilities that purify wastewater through the combined action of packing materials, plants, and microorganisms. Compared with traditional wastewater treatment plants, constructed wetlands have significant advantages such as lower investment and lower operating costs. In rural areas, where the population density is relatively low, the investment in constructed wetlands can generally be reduced by 1 / 3 to 1 / 2 compared to traditional wastewater treatment plants. During the treatment process, constructed wetlands mainly use gravity flow, resulting in virtually no energy consumption and low operating costs. The price of treating one ton of wastewater at a wastewater treatment plant is about 1 yuan, while the average cost of constructing a constructed wetland is less than 0.2 yuan. Therefore, in rural areas with low population density, constructing constructed wetlands is more economical than traditional wastewater treatment plants.

[0003] Before use and after reaching their service life, the packing material of constructed wetland wastewater treatment systems needs to be cleaned to remove various debris adhering to the surface of the packing material, thereby reducing the chance of blockage and ensuring the smooth flow of water in the constructed wetland.

[0004] A search revealed that patent CN112827871A discloses a cleaning device for filler material in artificial wetlands and its usage method. The device uses a double rotating rod to stir and clean the filler material, replacing the traditional manual washing method. This method offers high cleaning efficiency and excellent cleaning results. The drive shaft and cam work in conjunction with the double rotating rod to stir the filler material, ensuring uniform cleaning and guaranteeing that every side of the filler material can contact the cleaning brush, resulting in more even cleaning and further improving the cleaning effect.

[0005] While the above solution can effectively clean the packing material, its structure is too complex, and the cleaning operation is carried out inside the cleaning tank. Before the packing material in the cleaning tank is completely cleaned and discharged, packing material cannot be introduced into the cleaning tank, making continuous cleaning impossible and resulting in low efficiency, which needs to be improved.

[0025] To address the aforementioned issues, this application provides a cleaning device for agricultural wastewater wetland filler, which can perform continuous cleaning, has high cleaning efficiency for filler, and exhibits good performance.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] See Figure 1-2The aforementioned agricultural waste wetland filler cleaning device includes a support frame 2 and a cleaning tank 1 fixedly installed on the support frame 2. A sewage pipe 3 is installed through the bottom of the cleaning tank 1. A rotating drum 4 is rotatably installed inside the cleaning tank 1. A reduction motor 10 for driving the rotating drum 4 is fixedly installed on the outer wall of the cleaning tank 1. Through holes 5 are evenly opened on the outer peripheral wall of the rotating drum 4. A spiral brush 6 is fixedly connected inside the rotating drum 4, and bristles 7 are provided on the inner peripheral wall and both outer walls of the spiral brush 6. A feeding hopper 11 is installed through one end of the cleaning tank 1, and the feeding hopper 11 is connected to the feed end of the rotating drum 4. A discharge trough 12 is fixedly installed through the other end of the cleaning tank 1. The feed end of the discharge trough 12 is semi-enclosed on the outside of the discharge end of the rotating drum 4. A spray pipe 13 is installed inside the rotating drum 4, and spray nozzles 14 are evenly installed on the outer wall of the spray pipe 13 inside the rotating drum 4.

[0028] During operation, after connecting the spray pipe 13 to the water supply pipeline, the geared motor 10 is started to drive the rotating drum 4 to rotate in the cleaning tank 1. Then, the packing is fed into the rotating drum 4 from the feeding hopper 11. During the rotation of the rotating drum 4, the packing will tumble inside the rotating drum 4, and under the action of the spiral brush strip 6, the discharge end of the packing box rotating drum 4 will move. At the same time, the brush bristles 7 can brush the outer wall of the packing, while the water sprayed from the nozzle 14 can rinse the packing to ensure the cleaning effect of the packing. The packing discharged from the rotating drum 4 will be discharged out of the cleaning tank 1 through the discharge trough 12. The sewage generated during the cleaning process will be discharged from the drain pipe 3 at the bottom of the cleaning tank 1 for easy collection of sewage.

[0029] In some embodiments, a connecting seat 8 is provided on the inner side of the discharge end of the rotating drum 4. Support rods 9 are uniformly fixedly connected to the outer peripheral wall of the connecting seat 8. The outer end of the support rods 9 is fixedly connected to the inner wall of the rotating drum 4. The output shaft of the reduction motor 10 passes into the cleaning tank 1 and is fixedly connected to the connecting seat 8 through a coupling. The water inlet end of the spray pipe 13 passes out of the cleaning tank 1 and is fixedly connected to the cleaning tank 1 through a fixed seat 15. One end of the spray pipe 13 located inside the rotating drum 4 is blocked, and the other end of the spray pipe 13 located inside the rotating drum 4 is rotatably connected to the connecting seat 8 through a bearing seat.

[0030] When in operation, starting the geared motor 10 will drive the rotating drum 4 to rotate in the cleaning tank 1 through the connecting seat 8 and the support rod 9. The connecting seat 8 can support the spray pipe 13 through the bearing seat. The water inlet end of the spray pipe 13 is supported by the fixed seat 15 to ensure the stability of the spray pipe 13.

[0031] In some embodiments, the rotating drum 4 is inclined in the cleaning tank 1, and the feed end of the rotating drum 4 is higher than the discharge end of the rotating drum 4.

[0032] During operation, the feed end of the rotating drum 4 is slightly higher than the discharge end of the rotating drum 4, so that the packing material inside the rotating drum 4 can move towards the discharge end of the rotating drum 4.

[0033] In some implementations, see Figure 3 Both ends of the outer wall of the rotating drum 4 are fixedly fitted with collars 20. Two retainers 16 are fixedly installed in the cleaning tank 1. The collars 20 and the corresponding retainers 16 are rolled together. The retainer 16 includes a frame 17 fixedly installed in the cleaning tank 1. The inner side of the frame 17 is rotatably arranged with guide wheels 18 through a wheel frame. The guide wheels 18 are circumferentially distributed on the outer side of the corresponding collars 20. The outer peripheral wall of the guide wheels 18 is provided with an annular groove 19. The groove width of the annular groove 19 is adapted to the width of the collar 20. The outer edge of the collar 20 is located in the annular groove 19.

[0034] During operation, the two retainers 16 cooperate with the collar 20 to support and limit the rotating drum 4 in the cleaning tank 1 using the annular groove 19 on the guide wheel 18, thus preventing the rotating drum 4 from moving around in the cleaning tank 1.
