Description

Technical Field

[0001] The present invention relates to the technical field of sewage separation, and more particularly to a device for separating and treating river sewage sludge. Background Art

[0002] The separation and treatment of river sewage sludge refers to the separation and treatment of the sewage sludge mixture in the river through processes such as sewage pretreatment, filtration, and separate treatment of sludge separation, purifying the water resources and recycling the sludge in the water.

[0003] In the prior art, sewage treatment usually uses a filter screen to filter the silt in the sewage. However, during use, the silt will gradually fall due to gravity, and the flowing sewage has a certain traction on the silt, causing the silt to gradually accumulate on the filter screen. As the use time increases, a large amount of silt will connect to one side of the filter screen in the form of a slope, thus affecting the normal use of the filter screen. And in the field of water treatment, filter plates, as a common solid-liquid separation device, are widely used in the water purification processes of rivers, lakes, and sewage treatment plants, etc. However, due to the presence of various microorganisms in the water body, these tiny organisms will inevitably adhere to the micropores or surfaces of the filter plates during the filtration process, forming a biofilm, which affects the filtration effect of the filter plates, and the long-term accumulation of microorganisms will also affect the water quality.

Specific embodiments

[0036] To make the objectives, 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 with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0037] Example 1, referring to Figures 1-11 , a river sewage and sludge separation and treatment device, including a reservoir 1, a diversion pool 2, and a purification pool 3. A filtering component 9 is provided inside the purification pool 3. The filtering component 9 includes a filter cylinder 92, and further includes:

[0038] A sewage discharge component 4, the sewage discharge component 4 is located inside the filter cylinder 92, and the sewage discharge component 4 discharges the sludge on the inner wall of the filter cylinder 92 by using the flushing of water flow;

[0039] A storage component 5, the storage component 5 is located above the filter cylinder 92, and the storage component 5 uses the stored bleaching powder and cooperates with the flushing liquid to clean the biofilm on the inner wall of the filter cylinder 92;

[0040] A cleaning component 7, the cleaning component 7 is fixedly connected to the purification pool 3, and the cleaning component 7 cleans the filter cylinder 92 by spraying water;

[0041] The flapping component 8 is located below the cleaning component 7. The flapping component 8 utilizes the vibration generated by flapping to clean the sludge on the inner wall of the filter cartridge 92;

[0042] The floating component 10 is located on one side of the filter cartridge 92. The floating component 10 controls the discharge of bleaching powder according to the water level height.

[0043] Furthermore, the reservoir 1 is fixedly connected to the diversion pool 2, the diversion pool 2 is fixedly connected to the purification pool 3. One end of the purification pool 3 close to the diversion pool 2 is rotatably connected to the filter cartridge 92. A spiral impact plate 93 is circumferentially and arrayedly distributed on the inner wall of one end of the filter cartridge 92. A plurality of circumferentially and arrayedly distributed top blocks 91 are fixedly connected to the other end of the filter cartridge 92. One end side wall of the top block 91 is arc-shaped;

[0044] It should be noted that after the reservoir 1, the diversion pool 2 and the purification pool 3 are installed at the corresponding locations, when the river water passes through the reservoir 1, it starts to converge through the diversion pool 2, thereby increasing the flow rate and flow volume 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 pool 3. While filtering the river water, the centrifugal force generated by the rotation can also improve the filtering efficiency. And within the normal use range, the height of the water level is lower than the height of a single spiral impact plate 93 at the lower end of the filter cartridge 92, so as to ensure the impact effect, reduce the use of external driving resources. Finally, the filtered river water is discharged from the filter cartridge 92 into the purification pool 3 for further utilization.

[0045] The flapping component 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 pool 3. The support plate 81 is sleeved on the outer wall of the sewage discharge pipe 41. One end of the support rod 82 is fixedly connected to the support plate 81. The other end of the support rod 82 is rotatably connected to the flapping plate 83. An extension plate 821 is fixedly connected to the side wall of the support rod 82. An extrusion spring 84 is fixedly connected to the upper end of the extension plate 821. The upper end of the extrusion spring 84 is fixedly connected to the side wall of the flapping plate 83. A convex block 85 that cooperates with the top block 91 is fixedly connected to one side of the flapping plate 83;

[0046] It should be noted that while the filter cartridge 92 rotates for filtration, sludge and impurity ash in the river water will gradually adhere to the inner wall of the filter cartridge 92, which will affect the filtration 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 relative to the convex block 85. Through the interaction between the two, one end of the flapping plate 83 will be lifted, and the other end of the flapping plate 83 will compress the compression spring 84. During the gradual lifting of the flapping plate 83, the bottom end of the cleaning box 72 will be knocked. When the top block 91 separates from the convex block 85, due to the self-weight of the flapping plate 83 and the elastic recovery of the compression spring 84, the flapping plate 83 will be driven to flap the outer wall of the filter cartridge 92. Thus, through the vibration generated by the flapping, part of the sludge adhering to the inner wall of the filter cartridge 92 will be shaken off into the inside of the receiving frame 42 and finally slide into the inside of the sewage pipe 41, so as to reduce the adhesion of sludge on the inner wall of the filter cartridge 92, improve the filtration effect, and at the same time reduce the accumulation of sludge inside the filter cartridge 92 and ensure the rotation effect of the filter cartridge 92.

[0047] The cleaning assembly 7 includes a piston cylinder 71, a cleaning box 72 and a water suction pipe 73. Positioning rods 74 are fixedly connected to both sides of the cleaning box 72. The positioning rods 74 are arranged in an "L" shape. One end of the positioning rod 74 is fixedly connected to the purification tank 3. A spray head 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 suction pipe 73 respectively. A push plate 75 is connected to the inner wall of the cleaning box 72. The push plate 75 is made of rubber material. A support seat 522 is fixedly connected to one side of the cleaning box 72; The piston cylinder 71 is arranged in an "L" shape. One end of the piston cylinder 71 is provided with a first piston rod 711 and a first return spring 712. The other end of the piston cylinder 71 is provided with a second piston rod 713 and a second return spring 714. Both the first piston rod 711 and the second piston rod 713 are arranged in a "T" shape. The first return spring 712 and the second return spring 714 are respectively sleeved on the outer walls of the first piston rod 711 and the second piston rod 713. Two ends of the first return spring 712 are respectively fixedly connected to the inner wall of the piston cylinder 71 and the side wall of the first piston rod 711. Two ends of the second return spring 714 are respectively fixedly connected to the inner wall of the piston cylinder 71 and the side wall of the second piston rod 713. One end of the second piston rod 713 penetrates through the side wall of the cleaning box 72 and is fixedly connected to the push plate 75; One end of the water suction pipe 73 far away from the cleaning box 72 is fixedly connected with an expansion cylinder 731. An expansion spring 732 and a plugging block 733 are arranged inside the expansion cylinder 731. Two ends of the expansion spring 732 are respectively fixedly connected to the inner wall of the expansion cylinder 731 and the side wall of the plugging block 733.

[0048] It should be noted that during the lifting process of the above-mentioned flapping plate 83, its side wall will squeeze the piston rod 711, so that the first return spring 712 is compressed. Also, since the piston rod 711 and the piston rod 713 are in sealed sliding connection with the piston cylinder 71, the air inside the piston cylinder 71 is constant. When the air at one end is compressed, it will drive the piston rod 713 at the other end to be squeezed, so that the piston rod 713 drives the push plate 75 to move towards the gear 5211 side. At the same time, the filtered water inside the cleaning tank 72 is squeezed, and the local flushing of the filter cartridge 92 is realized through the nozzle 721. At the same time, it cooperates with the flapping of the flapping plate 83 to further improve the cleaning of the filter cartridge 92. And the sewage generated by the flushing falls into the inside of the receiving frame 42, and at the same time, it cooperates with the impact of the water flow to drive the sludge to flow inside the sewage discharge pipe 41, so as to realize the discharge of the sludge, reduce the burden of the rotation of the filter cartridge 92, and avoid the accumulation and blockage of the sludge in the sewage discharge pipe 41. In addition, the height of the filtered water inside the cleaning tank 72 is higher than the connection part of the water extraction pipe 73 and the cleaning tank 72, and the filtered water does not fill the entire cleaning tank 72. During the movement of the push plate 75, due to the extrusion of the internal space of the cleaning tank 72, the blocking block 733 will block the end of the water extraction 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;

[0049] In addition, when the flapping plate 83 resets, the piston rod 711 is no longer squeezed, and the first return spring 712 and the second return spring 714 drive the piston rod 711 and the piston rod 713 to return to their original positions respectively. At this time, due to the movement of the push plate 75, the internal capacity of the cleaning tank 72 expands and the pressure decreases. At this time, the filtered water on the inner wall of the water extraction pipe 73 will automatically supplement the inside of the cleaning tank 72. At the same time, due to the pressure effect, the blocking block 733 will move upward and compress the telescopic spring 732. During this process, the filtered water inside the purification tank 3 will be automatically sucked into the water extraction pipe 73 for supplementation, waiting for the next flushing of the cleaning tank 72. The advantage of doing this is not only to avoid the use of external driving equipment, but also to utilize the filtered river water, thereby saving resources and reducing costs.

[0050] Refer to Figures 2-5 As shown in the figure, 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 with a fixing plate 43. The other end of the sewage discharge pipe 41 penetrates the side walls of the filter cartridge 92 and 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 is fixedly connected to the purification tank 3.

[0051] 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.

[0052] Example 2, refer to Figure 5 , Figure 6 and Figure 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;

[0053] 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;

[0054] 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.

[0055] 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 cylindrically arranged, 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 penetrates 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 cylinder 92. A protective cover 6 is arranged outside the rack 104, and the protective cover 6 is fixedly connected to the cleaning tank 722.

[0056] It should be noted that when too much microbial film adheres to the inner wall of the filter cylinder 92, the filtration speed and efficiency of the filter cylinder 92 will decrease. At this time, due to the constant river water flow rate, the water level position at the opening of the filter cylinder 92 will gradually rise. In addition, the floating ball 101 can be made of polyurethane, polyurea material, wood or rubber, etc. In this device, the floating ball 101 uses polyurea material as the outer protective layer, and polyurethane foam material or plastic foam body is used as the buffer medium inside. Compared with the traditional plastic floating ball, it has greater buoyancy and longer service life. Therefore, during the rising process of the water level, the floating ball 101 drives the movable rod 103 to move upward synchronously through buoyancy, and then drives the rack 104 to move upward. During the upward movement of the rack 104, due to its meshing connection with the gear 5211, it can drive the rotating rod 521 to rotate, and the support seat 522 ensures the stable effect 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 limiting ring 102 to prevent the movable rod 103 from contacting the filter cylinder 92 and affecting the filtration effect, so as to eliminate the microorganisms on the inner wall of the filter cylinder 92 according to the normal water level height, and avoid the changes in the color, taste and smell of the water body caused by the long-term accumulation of microorganisms.

[0057] It should be noted that the specific model and specification of the motor need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0058] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
