However, during use, the sludge will gradually fall due to gravity, and the flowing sewage has a certain traction on the sludge, so that the sludge will gradually accumulate on the filter. As the use time increases, a large amount of sludge will dock on one side of the filter in a sloped manner, thereby affecting the normal use of the filter. In the field of water treatment, filter plates, as a common solid-liquid separation equipment, are widely used in water purification processes in rivers, lakes, and sewage treatment plants. However, due to the presence of various microorganisms in the water body, these tiny life forms will inevitably adhere to the micropores or surface of the filter plate during the filtration process to form a biofilm, thereby affecting the filtration effect of the filter plate, and the long-term accumulation of microorganisms will also affect the water quality.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1, refer to Figure 1-Figure 11 A river sewage sludge separation and treatment device comprises a water storage tank 1, a drainage tank 2 and a purification tank 3. A filter assembly 9 is arranged inside the purification tank 3. The filter assembly 9 comprises a filter cartridge 92 and further comprises: The sewage discharge component 4 is located inside the filter cartridge 92, and the sewage discharge component 4 uses water flow to flush the sludge on the inner wall of the filter cartridge 92; The material storage component 5 is located above the filter cartridge 92. The material storage component 5 uses the stored bleaching powder and the flushing liquid to clean the biofilm on the inner wall of the filter cartridge 92; A cleaning component 7, which is fixedly connected to the purification tank 3, and the cleaning component 7 cleans the filter cartridge 92 by spraying water; The beating assembly 8 is located below the cleaning assembly 7, and the beating assembly 8 uses the vibration generated by beating to clean the sludge on the inner wall of the filter cartridge 92; The floating assembly 10 is located on one side of the filter cartridge 92 and controls the discharge of the bleaching powder according to the water level.

[0021] Furthermore, the water storage tank 1 is fixedly connected to the drainage tank 2, the drainage tank 2 is fixedly connected to the purification tank 3, one end of the purification tank 3 close to the drainage tank 2 is rotatably connected to the filter cartridge 92, a spiral impact plate 93 is distributed in a circumferential array on the inner wall of one end of the filter cartridge 92, and the other end of the filter cartridge 92 is fixedly connected to a plurality of top blocks 91 distributed in a circumferential array, and one end side wall of the top block 91 is arranged in an arc shape; It should be noted that after the water storage tank 1, the drainage tank 2 and the purification tank 3 are installed at the corresponding locations, when the river water passes through the water storage tank 1, it begins to converge through the drainage tank 2, thereby increasing the flow rate and flow of the river water. Subsequently, the impact force of the water flow on the spiral impact plate 93 is used to realize the rotation of the filter cartridge 92 inside the purification tank 3. While completing the filtration of the river water, the filtration efficiency can also be improved by the centrifugal force generated by the rotation. In addition, within the normal use range, the water level is lower than the height of the single spiral impact plate 93 at the lower end of the filter cartridge 92, thereby ensuring the impact effect and reducing the use of external driving resources. Finally, the filtered river water is discharged from the filter cartridge 92 to the inside of the purification tank 3 for the next step of utilization.

[0022] The flapping assembly 8 includes a support plate 81, a support rod 82 and a flapping plate 83. Both ends of the support plate 81 are fixedly connected to the inner wall of the purification tank 3. The support plate 81 is sleeved on the outer wall of the sewage pipe 41. One end of the support rod 82 is fixedly connected to the support plate 81, and the other end of the support rod 82 is rotatably connected to the flapping plate 83. The side wall of the support rod 82 is fixedly connected with an extension plate 821. The upper end of the extension plate 821 is fixedly connected with an extrusion spring 84. The upper end of the extrusion spring 84 is fixedly connected to the side wall of the flapping plate 83. One side of the flapping plate 83 is fixedly connected with a protrusion 85 that matches the top block 91. It should be noted that: while the filter cartridge 92 is rotating and filtering, the sludge and impurity ash in the river water will gradually adhere to the inner wall of the filter cartridge 92, thereby affecting the filtering effect. However, during the rotation of the filter cartridge 92, the top block 91 will be driven to rotate together. During the movement of the top block 91, it will slide against the protrusion 85. Through the interaction between the two, one end of the flapping plate 83 is driven to rise, and the other end of the flapping plate 83 will compress the extrusion spring 84. During the gradual lifting of the flapping plate 83, the bottom of the cleaning box 72 will be pressed. The top block 91 is knocked on the protrusion 85 when it is separated from the projection 85. The flapping plate 83 is driven by its own weight and the elastic recovery of the extrusion spring 84 to flap the outer wall of the filter cartridge 92. As a result, the vibration generated by the flapping can shake off part of the sludge attached to the inner wall of the filter cartridge 92 into the interior of the receiving frame 42, and finally slide into the interior of the sewage pipe 41, thereby reducing the adhesion of sludge on the inner wall of the filter cartridge 92 and improving the filtering effect. At the same time, it can reduce the accumulation of sludge inside the filter cartridge 92 and ensure the rotation effect of the filter cartridge 92.

[0023] The cleaning assembly 7 includes a piston cylinder 71, a cleaning box 72 and a water pumping pipe 73. Positioning rods 74 are fixedly connected to both sides of the cleaning box 72. The positioning rods 74 are set in an "L" shape. One end of the positioning rod 74 is fixedly connected to the purification tank 3. A nozzle 721 is provided at the lower end of the cleaning box 72. A limiting plate 722 is fixedly connected to one side of the cleaning box 72. The cleaning box 72 is fixedly connected to the piston cylinder 71 and the water pumping pipe 73 respectively. The inner wall of the cleaning box 72 is connected to a push plate 75. The push plate 75 is made of rubber. A support seat 522 is fixedly connected to one side of the cleaning box 72. The piston cylinder 71 is set in an "L" shape. A piston rod 711 and a return spring 712 are provided at one end of the piston cylinder 71. A piston rod 713 and a return spring 714 are provided at the other end of the piston cylinder 71. 1 and piston rod 2 713 are both arranged in a "T" shape, and the return spring 1 712 and the return spring 2 714 are respectively sleeved on the outer walls of the piston rod 1 711 and the piston rod 2 713, and the two ends of the return spring 1 712 are respectively fixedly connected to the inner wall of the piston cylinder 71 and the side wall of the piston rod 1 711, and the two ends of the return spring 2 714 are respectively fixedly connected to the inner wall of the piston cylinder 71 and the side wall of the piston rod 2 713, and one end of the piston rod 2 713 passes through the side wall of the cleaning box 72 and is fixedly connected to the push plate 75; the end of the water suction pipe 73 away from the cleaning box 72 is fixedly connected to the expansion cylinder 731, and the expansion cylinder 731 is provided with a telescopic spring 732 and a blocking block 733, and the two ends of the telescopic spring 732 are respectively fixedly connected to the inner wall of the expansion cylinder 731 and the side wall of the blocking block 733.

[0024] It should be noted that: during the lifting process of the above-mentioned flapping plate 83, its side wall will squeeze the piston rod 1 711, thereby compressing the return spring 1 712. Since the piston rod 1 711 and the piston rod 2 713 are sealed and slidably connected with the piston cylinder 71, the air inside the piston cylinder 71 is constant. When the air at one end is compressed, the piston rod 2 713 at the other end will be squeezed, so that one end of the piston rod 2 713 drives the push plate 75 to move toward the side of the gear 5211, squeezing the filtered water inside the cleaning box 72, and realizing local flushing of the filter cartridge 92 through the nozzle 721. At the same time, the slapping of the flapping plate 83 further improves the filter cartridge. 92 is cleaned, and the sewage generated by flushing falls into the inside of the receiving frame 42. At the same time, the impact of the water flow drives the sludge to flow inside the sewage pipe 41, thereby realizing the discharge of the sludge, reducing the burden of the filter cartridge 92 on rotating, and avoiding the accumulation and blockage of the sludge in the sewage pipe 41. In addition, the height of the filtered water inside the cleaning box 72 is higher than the connection between the suction pipe 73 and the cleaning box 72, and the filtered water does not fill the entire cleaning box 72. During the movement of the push plate 75, the internal space of the cleaning box 72 is squeezed. At this time, the blocking block 733 will block the end of the suction pipe 73 to avoid the discharge of water flow and ensure the effective flushing of the nozzle 721, and the nozzle 721 is a one-way nozzle; In addition, when the flapping plate 83 is reset, the piston rod 1 711 is no longer squeezed, and the reset spring 1 712 and the reset spring 2 714 respectively drive the piston rod 1 711 and the piston rod 2 713 to return to their original positions. At this time, the movement of the push plate 75 causes the internal capacity of the cleaning box 72 to expand and the pressure to decrease. At this time, the filtered water on the inner wall of the suction pipe 73 will be automatically replenished into the cleaning box 72. At the same time, due to the pressure, the blocking block 733 will move up and compress the telescopic spring 732. In this process, the filtered water inside the purification tank 3 will be automatically sucked into the suction pipe 73 for replenishment, waiting for the next spraying of the cleaning box 72. The advantage of this is that it not only avoids the use of external driving equipment, but also utilizes the filtered river water, thereby saving resources and reducing costs.

[0025] Reference Figure 2-Figure 5 , further; the sewage discharge assembly 4 includes a sewage discharge pipe 41 and a receiving frame 42, one end of the sewage discharge pipe 41 is fixedly connected to the receiving frame 42, the sewage discharge pipe 41 is arranged in an "L" shape, one end of the sewage discharge pipe 41 located inside the filter cartridge 92 is fixedly connected to a fixing plate 43, the other end of the sewage discharge pipe 41 passes through the filter cartridge 92 and the side wall of the purification tank 3, the outer wall of the sewage discharge pipe 41 is rotatably connected to the side wall of the filter cartridge 92, and the sewage discharge pipe 41 and the purification tank 3 are fixedly connected.

[0026] It should be noted that the receiving frame 42 can effectively prevent the splashing of sludge during the cleaning process of the filter cartridge 92, and can collect the cleaned sludge in a centralized manner to improve the cleaning effect. The inclined surface of the receiving frame 42 can effectively cooperate with the impact of the water flow to quickly realize the sliding of the sludge. In addition, the receiving frame 42 and the sewage pipe 41 are both made of stainless steel, which can effectively alleviate the corrosion rate of the sludge, and at the same time reduce the adhesion and aggregation of microorganisms in the river water, while ensuring the discharge efficiency of the sludge.

[0027] Example 2, refer to Figure 5 , Figure 6 and Fig.11 , further; the storage assembly 5 includes a storage box 51, a blanking frame 52 and a gear 5211, the side wall of the blanking frame 52 is rotatably connected to a rotating rod 521, the outer wall of the rotating rod 521 is fixedly connected to a plurality of scrapers 5212 distributed in a circumferential array, the scraper 5212 and one end of the rotating rod 521 are located inside the blanking frame 52, one end of the rotating rod 521 passes through the blanking frame 52 and the support seat 522 and is fixedly connected to the gear 5211, and the inner wall of the blanking frame 52 is rotatably connected to a one-way discharge plate 523 through a torsion spring; It should be noted that: in the process of gear 5211 driving rotating rod 521 to rotate, multiple scrapers 5212 will rotate, and then scrapers 5212 will scrape the bleaching powder inside storage box 51 and transport the bleaching powder between two adjacent scrapers 5212 to the upper surface of two one-way discharge plates 523 as they rotate. At this time, gravity will separate the two one-way discharge plates 523, and finally discharge the bleaching powder through discharge frame 52 into the cleaning box 72 to mix with filtered water. In this process, the bleaching powder accumulated inside storage box 51 can be effectively loosened by the beating vibration of cleaning box 72 by beating plate 83 to ensure smooth discharge. , and because bleaching powder has good solubility and can be quickly dissolved in water, and the sodium hypochlorite in the bleaching powder can release effective chlorine components, which have strong oxidizing properties and can destroy the cell structure of microorganisms to achieve a killing effect. Therefore, in the next spraying process, the mixed liquid will remove the microbial film on the inner wall of the filter cartridge 92, thereby eliminating the microbial film on the inner wall of the filter cartridge 92, thereby ensuring the filtering effect of the filter cartridge 92. In addition, the one-way discharge plate 523 can only be rotated downward by the torsion spring, and when the bleaching powder falls, it will automatically restore the closed state through the torsion spring, thereby effectively reducing the influence of the water vapor inside the cleaning box 72 on the bleaching powder inside the storage box 51; In addition, a detachably connected cover is provided at the upper end of the storage box 51, and the bleaching powder can be conveniently added and supplemented by opening the cover, and an observation window can be provided on the side wall of the storage box 51, so that the capacity of the material inside the storage box 51 can be understood in time, so that relevant personnel can add materials in time.

[0028] The floating assembly 10 includes a floating ball 101, a limiting ring 102, a movable rod 103 and a rack 104. One end of the movable rod 103 is cylindrical, and the other end of the movable rod 103 is plate-shaped. The limiting ring 102 is fixedly sleeved on the outer wall of one end of the movable rod 103. One end of the movable rod 103 is slidably connected to the fixed plate 43, and the limiting ring 102 is located above the fixed plate 43; one end of the rack 104 passes through the side wall of the limiting plate 722 and is fixedly connected to the side wall of the movable rod 103. The rack 104 is meshed with the gear 5211. One end of the movable rod 103 is located above the filter cartridge 92. A protective cover 6 is provided on the outer side of the rack 104, and the protective cover 6 is fixedly connected to the cleaning box 72. It should be noted that: when too much microbial film is attached to the inner wall of the filter cartridge 92, the filtering speed and efficiency of the filter cartridge 92 will be reduced. At this time, due to the constant flow rate of the river water, the river water level at the opening of the filter cartridge 92 will gradually rise. In addition, the floating ball 101 can be made of polyurethane, polyurea material, wood or rubber. In this device, the floating ball 101 uses polyurea material as the outer protective layer, and polyurethane foam material or plastic foam is used as the buffer medium inside. Compared with the traditional plastic floating ball, it has greater buoyancy and longer life. Therefore, during the rising water level, the floating ball 101 drives the movable rod 1 through the buoyancy. 03 rises synchronously, thereby driving the rack 104 to move upward. During the upward movement of the rack 104, the meshing connection between itself and the gear 5211 can drive the rotating rod 521 to rotate, and the support seat 522 is used to ensure the stability of the rotating rod 521 during operation. The function of the fixed plate 43 is, on the one hand, to ensure the movement of the movable rod 103, and on the other hand, to cooperate with the limit ring 102 to prevent the movable rod 103 from contacting the filter cartridge 92 and affecting the filtering effect, thereby achieving the elimination of microorganisms on the inner wall of the filter cartridge 92 according to the water level under normal circumstances, and avoiding the long-term accumulation of microorganisms that lead to changes in water color, taste and odor.

[0029] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
