Description

Technical Field

[0001] This utility model relates to the field of water ecological restoration technology, specifically a biological filter for water ecological restoration. Background Technology

[0002] A biological filter for water ecological restoration is a water environment treatment device based on the principle of biofilm method. It fills the filter with porous filter media such as gravel, ceramsite, activated carbon, and biological sponge to provide a carrier for microorganisms to attach and grow. When polluted water flows over the surface of the filter media, the microbial community on the filter media will decompose and remove pollutants such as organic matter, nitrogen and phosphorus nutrients, and suspended solids in the water through adsorption, degradation, and transformation. At the same time, the physical interception of the filter media can further purify the water quality, ultimately achieving water clarification and ecological function restoration. This device is widely used in the treatment of natural water bodies such as rivers, lakes, and wetlands, as well as the deep purification of wastewater treatment plant effluent. It has the characteristics of low operating cost, no secondary pollution, and the ability to promote the restoration of aquatic ecosystems.

[0003] Furthermore, biological filters are the core facilities for water purification in the field of aquatic ecological restoration. However, biological filters have obvious shortcomings in operation and maintenance in practical applications, making it difficult to balance purification efficiency and ease of cleaning. Traditional biological filters lack dedicated automatic cleaning structures for their filter components. After long-term use, the filter pores are easily clogged by deposits, requiring manual disassembly and cleaning, which is not only time-consuming and labor-intensive but also interrupts water purification operations. In addition, some filters equipped with cleaning structures cannot flexibly adjust the contact force of the cleaning components, making it difficult to adapt to the cleaning needs of different levels of deposits. Incomplete cleaning or over-cleaning that damages the filter plates often occurs, and the deposits after cleaning cannot be quickly collected and discharged, further reducing cleaning efficiency.

[0020] Combination Figures 1 to 11A biological filter for water ecological restoration includes a treatment tank 1, a filtration mechanism 2 fixedly connected inside the treatment tank 1, and a drive mechanism 3 fixedly connected to the top of the treatment tank 1. The filtration mechanism 2 includes a filter plate 21, which is fixedly connected to the inside of the treatment tank 1. A rack 212 is provided at the top of the treatment tank 1, and a gear 211 is meshed with the surface of the rack 212. A vertical rod 22 is fixedly connected inside the gear 211, and a sliding sleeve 221 is rotatably connected to the surface of the vertical rod 22. A gate-shaped strip 222 is slidably connected to one end of the sliding sleeve 221. I-shaped rings 23 are rotatably connected to the upper and lower ends of the surface of the vertical rod 22, and a first... A T-shaped ring rod 231 is rotatably connected to a second T-shaped ring rod 232. A vertical shaft 233 is fixedly connected to the top of an I-shaped ring 23.

A bottom ring 28 is rotatably connected to the bottom end of the vertical rod 22. A long... Rod 29, with both ends of the long rod 29 fixedly connected to the inside of the treatment pool 1. Positioning holes are opened on the surface of the first T-shaped ring rod 231 and the surface of the second T-shaped ring rod 232. The surface of the insertion rod 24 matches the inside of the positioning hole. A guide groove is opened inside the slide block 25. The surface of the slider 252 is slidably connected to the inside of the guide groove. There are two support rings 236. The surface of the top support ring 236 is fixedly connected to the top of the gate strip 222, and the surface of the bottom support ring 236 is fixedly connected to the bottom of the gate strip 222.

[0021] Furthermore, a perforation is made on the surface of the I-shaped ring 23, and the surface of the insert rod 24 passes through the perforation on the surface of the I-shaped ring 23. A circular hole is made on the surface of the supporting ring 236, and the surface of the vertical shaft 233 is slidably connected to the inside of the circular hole. There are two sets of slide blocks 25 and sliders 252. The front slider 252 is rotatably connected to the second T-shaped ring rod 232, and the back slider 252 is rotatably connected to the first T-shaped ring rod 231. Moving the slide block 25 allows the cleaning strip 27 to adjust its contact force with the surface of the filter plate 21. After the adjustment is completed, the insert rod 24 is re-engaged into the first T-shaped ring rod 231 and the second T-shaped ring rod 232 to complete the operation and adjust the cleaning force of the cleaning strip 27. Example

[0022] See Figures 1 to 11 Furthermore, based on Embodiment 1, the drive mechanism 3 further includes a portal frame 31, which is fixedly connected to the top of the treatment tank 1. A motor lead screw 32 is fixedly connected inside the portal frame 31, and a threaded block 33 is threadedly connected to the surface of the motor lead screw 32. The bottom of the threaded block 33 is rotatably connected to the top of the vertical rod 22. Vertical frames 34 are fixedly connected to the front and rear ends of the top of the treatment tank 1, and an electric push rod 35 is fixedly connected inside the vertical frame 34. A movable rod 36 is fixedly connected to the bottom end of the electric push rod 35, and a stop bar 37 is fixedly connected to the bottom end of the movable rod 36. A sliding groove is opened inside the portal frame 31, and the surface of the threaded block 33 is slidably connected to the inside of the sliding groove.

[0023] Furthermore, a support hole is opened inside the bottom end of the vertical frame 34, and the surface of the movable rod 36 is slidably connected to the support hole. The baffle 37 moves upward, so that the cleaned attachments inside the treatment pool 1 can be cleaned from the left end inside the treatment pool 1 to the right end inside the treatment pool 1 and then cleaned out of the treatment pool 1 through the opening, thus completing the corresponding cleaning operation.

[0024] In actual operation, when this device is used for aquatic ecological restoration in a biological filter, inlet and outlet ports are opened on the left and right sides of the treatment tank 1, respectively. A rectangular opening is also opened at the bottom right side of the treatment tank 1 to facilitate the discharge of debris. During water treatment, multi-stage filtration is required. Water flows in from the left side of the treatment tank 1 and is filtered by multiple filter plates 21 before being discharged from the right side. After a period of treatment, the surface of the filter plates 21 needs to be cleaned. The cleaning strips 27 can penetrate the filter holes on the surface of the filter plates 21. When cleaning the deposits on the filter plates 21, the motor screw 32 drives the threaded block 33 to move inside the portal seat 31, which in turn drives the vertical rod 22 to rotate and move under the meshing of the gear 211 on the surface of the rack 212. This allows the vertical rod to move. When the I-shaped ring 23 and the slide 25 move, the cleaning strip 27 cleans the deposits on the surface of the filter plate 21. When it is necessary to adjust the cleaning force of the cleaning strip 27, the support ring 236 is pulled upward to drive the gate strip 222 to slide upward, thereby driving the two support rings 236 to move upward and thus driving the insert rod 24 to disengage from the locking position inside the second T-shaped ring rod 232 and the first T-shaped ring rod 231. This releases the limiting effect of the first T-shaped ring rod 231 and the second T-shaped ring rod 232. Then the slide 25 can be moved to adjust the adhesion force of the cleaning strip 27 to the surface of the filter plate 21. After the adjustment is completed, the insert rod 24 is re-locked into the first T-shaped ring rod 231 and the second T-shaped ring rod 232 to complete the operation and adjust the cleaning force of the cleaning strip 27. In addition, after the cleaning is completed, when it is necessary to clean the attached objects, simply let the electric push rod 35 drive the movable rod 36 to move upward under the limit of the vertical frame 34, thereby driving the baffle 37 to move upward. In this way, the attached objects that have been cleaned inside the treatment pool 1 can be cleaned from the left end inside the treatment pool 1 to the right end inside the treatment pool 1 and then cleaned out of the treatment pool 1 through the opening, thus completing the corresponding cleaning operation.
