Description

Technical Field

[0001] This invention belongs to the technical field of sewage collection and treatment, and specifically relates to a sewage collection and treatment system. Background Technology

[0002] In recent years, after collecting sewage, sewage treatment systems typically employ a three-stage separation process in conjunction with sewage tanks. This process is mostly divided into three modules: preliminary interception, sedimentation and degradation, and deep purification. Sewage is connected to the sewage tank from the outside through pipes. At this point, it enters the preliminary interception stage, where large impurities are blocked and filtered. Then, it flows to the deep purification stage and is discharged through pipes, completing the purification process.

[0003] Currently, the sedimentation tank inside the sewage treatment plant is used to biodegrade sewage and remove organic pollutants during use. Impurities will settle at the bottom or adhere to the inner wall of the sedimentation tank. After a long period of sewage filtration, operators need to drain the water from the sewage treatment plant and clean the inside of the sedimentation tank. In the existing technology, operators usually need to use tools to shovel out the sediment from the bottom and sides, which is time-consuming and labor-intensive and cannot quickly clean the sedimentation tank. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater collection and treatment system that addresses the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A wastewater collection and treatment system includes a lifting component, comprising a wastewater tank, with two connecting rods fixedly connected to the middle section of the wastewater tank. An upward-moving plate for lifting sediment is slidably connected to the surfaces of the two connecting rods. A series assembly for assisting the movement of the upward-moving plate is provided between the connecting rods and the upward-moving plate. A power component for driving the series assembly is provided between the upward-moving plate and the series assembly. A scraping component includes scrapers slidably connected to both sides of the upward-moving plate. A pushing component for pushing out dirt is provided on the surface of the scrapers. A reset component for assisting the scrapers in reciprocating movement is provided between the scrapers and the upward-moving plate.

[0006] In a preferred embodiment of the present invention, the series assembly includes two connecting plates fixedly connected to the upper side of the upper moving plate. Both connecting plates are slidably connected to the connecting rod. A pull rope is fixedly connected to the upper side of each of the two connecting plates. Two support plates are fixedly connected to the inner walls of each of the two connecting rods. The pull rope abuts against the surface of the support plate. An inclined block is fixedly connected to the end of the pull rope away from the connecting plate. The inclined block is slidably connected to the lower side of the sewage tank. A series rope is fixedly connected to the inclined surface of the inclined block.

[0007] In a preferred embodiment of the present invention, the power assembly includes a mounting frame fixedly connected to the lower side of the sewage tank, a motor fixedly connected to the inner wall of the mounting frame, a turntable rotatably connected to the surface of the mounting frame, the turntable being in the shape of an "I", the output end of the motor being fixedly connected to the turntable, and the end of the connecting rope away from the inclined block being fixedly connected to the middle section of the turntable.

[0008] In a preferred embodiment of the present invention, the tail ends of the two connecting plates are both in contact with the inner wall of the sewage tank, and the height of the two connecting plates is lower than the height of the inclined surface of the scraper.

[0009] In a preferred embodiment of the present invention, the pallet is semi-circular, and an arc-shaped groove is formed on the outer surface of the pallet. The pull rope is located on the inner wall of the arc-shaped groove, and the size of the arc-shaped groove is larger than the size of the pull rope.

[0010] In a preferred embodiment of the present invention, a circular groove is provided on the lower side of the sewage tank, and the tail end of the motor is embedded in the interior of the circular groove, the size of the circular groove being adapted to the size of the motor.

[0011] In a preferred embodiment of the present invention, the gap of the turntable is adapted to the diameter of the connecting rope, and the side of the turntable near the connecting rope has a rounded corner.

[0012] In a preferred embodiment of the present invention, the pushing assembly includes two extension plates fixedly connected to the surface of the scraper, each extension plate having a top plate fixedly connected to its surface. The top plate is in contact with the inclined surface of the scraper, and each extension plate has a push plate rotatably connected to its surface. The arc surface of the push plate is in contact with the top plate.

[0013] In a preferred embodiment of the present invention, the reset assembly includes two telescopic rods fixedly connected to the inner wall of the scraper, the lower ends of the two telescopic rods being fixedly connected to the upper moving plate, and springs being sleeved on the surface of the two telescopic rods, with the two ends of the springs being fixedly connected to the upper moving plate and the scraper, respectively.

[0014] As a preferred embodiment of the present invention, the scraper has a side plate protruding on the side near the upper moving plate, and the side plate is slidably connected to the upper moving plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By using the lifting component and the power unit, the pull rope inside the series component can be driven to pull the connecting block, which in turn drives the upper plate to slide on the surface of the connecting rod. This helps the upper plate to move to the surface of the sewage tank, at which point the bottom sediment is lifted up. Operators can then easily clean the sediment, greatly increasing the convenience of cleaning the sediment and making it easier to remove the sediment from the inside of the sewage tank. The scraping component, along with the reset assembly and scraper, allows for multiple up-and-down movements as the upper plate moves upward. When dirt adheres tightly, the scraper is compressed and then springs back to its original position after scraping. This helps clean dirt from the sides as the upper plate moves upward, improving the smoothness of lifting dirt and reducing the burden on the motor to pull the upper plate via the connecting ropes and pull cords. This increases the speed of dirt removal while reducing damage caused by the mating of parts. Attached Figure Description

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0019] Reference Figures 1-6This is the first embodiment of the present invention. This embodiment provides a sewage collection and treatment system, including a lifting component and a sewage tank 10. Two connecting rods 11 are fixedly connected to the middle section of the sewage tank 10. An upper moving plate 12 for lifting sediment is slidably connected to the surface of the two connecting rods 11. A series assembly 13 for assisting the movement of the upper moving plate 12 is provided between the connecting rods 11 and the upper moving plate 12. A power assembly 14 for driving the series assembly 13 is provided between the upper moving plate 12 and the series assembly 13.

[0020] The sewage tank 10 is divided into three sections to treat sewage at different stages. The middle section is a sedimentation tank, where impurities inside the sewage can settle to the bottom or adhere to the side wall. At this time, the power component 14, in conjunction with the series component 13, drives the upper moving plate 12 to slide vertically upward, which can bring the upper moving plate 12 to the surface. At this time, the operator can easily and quickly clean the sediment on the surface of the upper moving plate 12 and facilitate the purification of sewage. The lifting component automatically lifts the sediment to the tank opening, replacing manual cleaning.

[0021] Furthermore, the series assembly 13 includes two connecting plates 131 fixedly connected to the upper side of the upper moving plate 12. Both connecting plates 131 are slidably connected to the connecting rod 11. Pull ropes 132 are fixedly connected to the upper side of both connecting plates 131. Two support plates 133 are fixedly connected to the inner wall of both connecting rods 11. The pull ropes 132 abut against the surface of the support plates 133. An inclined block 134 is fixedly connected to the end of the pull ropes 132 away from the connecting plate 131. The inclined block 134 is slidably connected to the lower side of the sewage tank 10. A series rope 135 is fixedly connected to the inclined surface of the inclined block 134. The power assembly 14 includes a mounting bracket 141 fixedly connected to the lower side of the sewage tank 10. A motor 142 is fixedly connected to the inner wall of the mounting bracket 141. A turntable 143 is rotatably connected to the surface of the mounting bracket 141. The turntable 143 is in the shape of an "I". The output end of the motor 142 is fixedly connected to the turntable 143. The end of the connecting rope 135 away from the inclined block 134 is fixedly connected to the middle section of the turntable 143.

[0022] The motor 142 efficiently drives the turntable 143 to rotate. During this process, the rotation of the turntable 143 not only achieves its own motion function but also causes the connecting rope 135 to gradually wind up into its internal space. The winding process of the connecting rope 135 is not independent but works in close coordination with the inclined block 134, further pulling the pull rope 132. Specifically, when the pull rope 132 is subjected to force from the inclined block 134, it works in conjunction with the support plate 133. This ingenious coordination allows the connecting plate 131 to be stably pulled upwards. As the connecting plate 131 moves upwards, the connected upward-moving plate 12 also moves upwards synchronously. This linkage mechanism greatly facilitates the cleaning of dirt, as it gradually lifts dirt from hard-to-reach locations to the surface. This eliminates the need for operators to laboriously venture into narrow or hidden spaces when cleaning dirt, significantly improving the efficiency and operability of the cleaning work. The entire system operates with a clear and efficient logic, fully demonstrating the precision and practicality of mechanical design, while also making cleaning work easier and more convenient.

[0023] Preferably, the tail ends of both connecting plates 131 are in contact with the inner wall of the sewage tank 10, and the height of both connecting plates 131 is lower than the height of the inclined surface of the scraper 20. The support plate 133 is semi-circular, and an arc-shaped groove is formed on the outer surface of the support plate 133. The pull rope 132 is located on the inner wall of the arc-shaped groove, and the size of the arc-shaped groove is larger than the size of the pull rope 132. A circular groove is formed on the lower side of the sewage tank 10, and the tail end of the motor 142 is embedded in the interior of the circular groove. The size of the circular groove is adapted to the size of the motor 142. The gap of the turntable 143 is adapted to the diameter of the connecting rope 135, and the side of the turntable 143 near the connecting rope 135 is rounded.

[0024] It should be noted that, since the connecting plate 131 is in close contact with the sewage tank 10, dirt will not enter the tail end of the connecting plate 131, thus affecting the smoothness of the upward sliding of the connecting plate 131. When the pull rope 132 is pulled by the motor 142, it is located in the arc-shaped groove of the support plate 133. The arc surface can reduce the friction damage to the pull rope 132 and improve the service life of the pull rope 132. Furthermore, since part of the motor 142 is embedded inside the sewage tank 10, the stability of the motor 142 operation can be further improved, and there will be no shaking. When the turntable 143 rotates, the rounded corners can guide the connecting rope 135 to enter the middle position of the turntable 143, reducing the friction damage from contact with the side and facilitating the winding operation of the connecting rope 135.

[0025] During use, after prolonged use of the sewage tank 10 for sewage collection and purification, a large amount of sediment will accumulate at the bottom of the tank. Regular cleaning of the sediment is necessary. At this time, the operator completely drains the sewage from the tank 10, ensuring the liquid level drops below the sediment surface to prevent residual sewage from interfering with subsequent operations and to prepare for sediment cleaning. This allows the motor 142 to be started, and its output drives the turntable 143 to rotate. The rotation of the turntable 143 causes the connecting rope 135 to wind around the central rod surface, achieving a winding effect. Simultaneously, it pulls the inclined block 134 towards the motor 142, which in turn pulls the pull rope 132. The pull rope 132, in conjunction with the support plates 133 at the upper and lower positions of the connecting rod 11, aligns with the connecting plate 131. Pulling the connecting plates 131 on both sides causes the upper plate 12 to move upward, which in turn moves the sediment on the surface of the upper plate 12 upward. After the connecting rope 135 is completely wound into the turntable 143, the upper plate 12 moves to the upper position of the sewage tank 10. At this time, the operator can easily clean the sediment on the surface, and the dirt will not fall back into the sewage tank 10. After the sediment is cleaned, the motor 142 can be operated to drive the turntable 143 to rotate in the opposite direction. At this time, the upper plate 12 is released from the limit and slides downward under the effect of gravity. Then, in conjunction with the pull rope 132 and the connecting inclined plate, the connecting rope 135 is pulled, which helps to remove the connecting rope 135 from the inside of the turntable 143, thereby realizing the resetting operation of the parts. The sediment can then be cleaned quickly again. Example 2

[0026] Reference Figures 1-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a scraping component, including a scraper 20 slidably connected to both sides of the upper moving plate 12. The surface of the scraper 20 is provided with a pushing component 21 for pushing out dirt. A reset component 22 is provided between the scraper 20 and the upper moving plate 12 to help the scraper 20 move back and forth. The pushing component 21 includes two extension plates 211 fixedly connected to the surface of the scraper 20. A top plate 212 is fixedly connected to the surface of each of the two extension plates 211. The top plate 212 is in contact with the inclined surface of the scraper 20. A push plate 213 is rotatably connected to the surface of each of the two extension plates 211. The arc surface of the push plate 213 is in contact with the top plate 212. The reset assembly 22 includes two telescopic rods 221 fixedly connected to the inner wall of the scraper 20. The lower ends of the two telescopic rods 221 are fixedly connected to the upper moving plate 12. Springs 222 are sleeved on the surface of the two telescopic rods 221, and the two ends of the springs 222 are fixedly connected to the upper moving plate 12 and the scraper 20, respectively.

[0027] Specifically, when the upper plate 12 moves upward, it will simultaneously drive the scraper 20 to move upward. The scraper 20 can help to scrape and clean the dirt on the side wall of the sewage tank 10. When encountering tightly attached dirt, the scraper 20 can be compressed in conjunction with the reset component 22. After the tightly attached dirt is scraped off, the spring 222 will drive the scraper 20 to reset and move upward. At this time, an impact can be generated, which can improve the scraping effect of the scraper 20, while reducing the resistance encountered by the scraper 20 and improving the smoothness of the scraping operation.

[0028] Preferably, the scraper 20 has a side plate protruding on the side near the upper moving plate 12, and the side plate is slidably connected to the upper moving plate 12.

[0029] It should be noted that the side plate has the function of limiting the scraper 20, which effectively prevents the scraper 20 from detaching from the upper moving plate 12. In addition, the side plate can further enhance the sealing performance between the scraper 20 and the upper moving plate 12 to a certain extent, thereby preventing sewage from penetrating into the internal structure of the parts, thus ensuring the normal operation of the entire device and the cleanliness of the internal parts.

[0030] During operation, as the upper moving plate 12 moves upward, it simultaneously drives the scraper 20 to rise as a whole. The scraper 20 is designed with a specific angled slope structure, which can effectively scrape away dirt and grime adhering to the side wall of the sewage tank 10 during the upward movement. If it encounters tightly adhered dirt, the scraper 20 will experience reverse resistance, which will compress the spring 222 at its rear, allowing the scraper 20 to slide backward relative to the upper moving plate 12 for cushioning. This cushioning design prevents the equipment from jamming and provides protection. When the scraper 20 slides to its limit position, its relative movement with the upper moving plate 12 stops, and the two form a rigid connection, working together with strong mechanical force to scrape away stubborn impurities. After the dirt is removed, the scraper 20 quickly rebounds and slides back towards the upper moving plate 12 under the restoring force of the spring 222. This rapid rebound action generates an impact force that strikes the surface of any remaining or incompletely removed impurities. This high-frequency impact greatly enhances the cleaning effect on the pool wall. Simultaneously, this intermittent impact scraping method, compared to continuous hard scraping, significantly reduces the continuous traction force required by the motor 142 via the pull rope 132, thus effectively reducing the operating load on the motor 142. Furthermore, a side plate is provided on the side of the scraper 20 near the upper moving plate 12. This design effectively prevents sewage and sludge particles from entering the internal space of the equipment when the scraper 20 slides up and down, protecting internal mechanical components (such as the spring 222) from contamination and corrosion, ensuring its long-term stable operation. When the scraper 20 slides downwards, it pushes the push plate 213 below it, causing it to rotate around the hinge point to a state nearly parallel to the direction of movement. At this time, the front of the push plate 213 effectively pushes the scraped impurities towards the center of the sewage pool, acting as a collection agent. When the scraper 20 slides upwards to reset, it drives the push plate 213 to rotate back to an inclined state. The dirt pushed to the center then falls and deposits on the surface of the upper moving plate 12 due to loss of support. Through the repeated up-and-down sliding cycles of the scraper 20, the pusher 213 also rotates repeatedly, continuously pushing and accumulating the dirt in the central area of ​​the pool bottom, forming a concentrated pile of sludge. This design allows operators to quickly and thoroughly clean the highly concentrated dirt after the upper plate 12 is raised to the top of the pool, greatly improving work efficiency.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
