Description

Technical Field

[0001] This utility model relates to the technical field of sludge scraping and suction devices, and in particular to a peripheral drive sludge scraping and suction machine. Background Technology

[0002] Peripheral drive sludge scraper is a key sludge treatment device used in wastewater treatment projects for radial flow sedimentation tanks (circular or square). Water enters from the center or periphery and flows radially. Its main function is to scrape the sludge settled at the bottom of the tank to the central sludge hopper, and at the same time, discharge the sludge out of the tank through a sludge suction device to ensure the continuous and stable operation of the sedimentation tank.

[0003] Conventional sludge scrapers typically operate in only one direction, such as clockwise, pushing sludge towards the central sludge hopper as the machine rotates with the frame. When the equipment needs to rotate counter-clockwise for maintenance or adjustment, the scraper angle conflicts with the rotation direction. This not only fails to scrape sludge but may also push already accumulated sludge towards the edge of the tank, leading to sludge residue in certain areas at the bottom, reducing the risk of blockage, and lowering the efficiency and stability of the entire wastewater treatment system. Lightweight substances in wastewater, due to their density being close to water or in a suspended state, are difficult for the scraping system to remove. These substances, removed by conventional sedimentation processes or targeting bottom sludge, will flow out of the treatment tank with the effluent. Some of these lightweight suspended substances may mix with the bottom sludge due to water flow disturbance, increasing the sludge's moisture content and viscosity, thus reducing scraping efficiency and leaving some sludge residue. This affects the cleanliness of the sedimentation tank, impacting sedimentation effectiveness and reducing wastewater treatment quality. Utility Model Content

[0004] The main purpose of this utility model is to provide a peripheral drive sludge scraper, which can effectively solve the problems of sludge residue in local areas at the bottom of the tank, reduce the risk of blockage, reduce the efficiency and stability of the entire sewage treatment system, reduce sludge scraping efficiency, and cause some sludge residue to remain, affecting the cleanliness of the sedimentation tank, affecting the sedimentation effect of the sedimentation tank, and reducing the quality of sewage treatment.

[0008] Furthermore, the bottom ends of the two transition pipes are connected to the top of the first connecting pipe, the rear side wall of the bridge is fixedly connected to the first support plate, the output end of the double suction pump is fixedly connected to the second connecting pipe, the bottom of the second connecting pipe is fixedly connected to the upper side wall of the first support plate, the left end of the second connecting pipe is connected to the sewage pipe, and the bottom end of the sewage pipe is located inside the sewage collection tank.

[0009] Furthermore, a second fixing ring is fixedly connected to the outer side of the top of the support column, and a push plate is fixedly connected to the outer side of each of the second fixing rings.

The two sliders are slidably connected inside the groove, and a scraper is fixedly connected inside each of the two connecting blocks. The outer walls of the two scrapers are correspondingly arranged to the interior of the treatment pool.

[0010] Furthermore, each of the bottom walls of the treatment pool is provided with a placement groove, and an anti-slip cover is provided at the top of each placement groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1.

The guide plate, located at the bottom of the device box and in front of the middle of the inlet pipe, directs the sludge towards the inlet pipe. At this time, the double-suction pump at the top of the cable tray starts, creating negative pressure in the first connecting pipe through the first transfer pipe and transition pipe, drawing the sludge collected in the inlet pipe into the device box. This effectively reduces sludge residue at the bottom of the tank, keeps the sedimentation tank clean, improves wastewater treatment efficiency, and ensures thorough sludge removal.

[0013] 2.

Each branch pipe connects to a nozzle at its top, and the nozzle is positioned in a placement trough on the bottom wall of the treatment tank. The anti-slip cover at the top of the placement trough not only protects the nozzle from direct sludge coverage that could affect the spraying effect, but also guides the airflow direction, effectively improving sludge scraping efficiency, reducing sludge residue, ensuring a clean tank bottom, and ensuring timely sludge removal, thus reducing the risk of clogging the suction port.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1 - Figure 6As shown: The peripheral drive sludge scraper includes a treatment tank 1. A sludge collection trough 2 is fixedly connected to the top outer side of the treatment tank 1. Impurities are collected through the sludge collection trough 2. A sliding groove 3 is opened on the top outer side of the treatment tank 1. A fixing plate 4 is fixedly connected to the outer side of the sludge collection trough 2. A guide rail 5 is fixedly connected to the top of the fixing plate 4. The treatment tank 1 is installed in the excavated hole through the fixing plate 4, which is like a tank plate on the outside of the treatment tank 1. The guide rail 5 on the top is connected through the fixing plate 4.

[0019] A cable tray 6 is installed on the top of the treatment pool 1. Guardrails 7 are fixedly connected to both the front and rear sides of the cable tray 6 to prevent workers from falling while standing on it. First connecting plates 8 are fixedly connected to the bottom left and right sides of each guardrail 7. Two casters 9 are rotatably connected to the bottom of each first connecting plate 8. The four casters 9 are internally slidably connected to the outside of guide rails 5. When the equipment is started, the casters 9 first obtain power through an external motor and drive device, and move in a circular motion along the upper guide rail 5 on the top of the fixed plate 4. Since the casters 9 are fixed to the first connecting plates 8 at the bottom of the guardrails 7 on both sides of the cable tray 6, their movement directly drives the cable tray 6 to rotate about the support column 12 at the center of the treatment pool 1.

[0020] Each cable tray 6 has a fixed support bracket 10 at its bottom. Each of the four support brackets 10 has a fixed device box 11 at its bottom. The support brackets 10 at the bottom of the cable tray 6 connect to and support the device box 11. When the cable tray 6 is rotated, the device box 11 at the bottom also rotates synchronously inside the treatment tank 1. A support column 12 is fixedly connected to the bottom of the cable tray 6. The bottom end of the support column 12 penetrates into the interior of the treatment tank 1. A first fixing ring 13 is fixedly connected to the outer side of the bottom end of the support column 12. The support column 12 supports the top of the cable tray 6 and, by penetrating into the interior of the treatment tank 1, also drives the support column 12 and the outer first fixing ring 13 to rotate.

[0021] like Figure 1 - Figure 6As shown, the middle part of the device box 11 is fixedly connected to the outer wall of the first fixing ring 13. The top of the device box 11 is fixedly connected to the first connecting pipe 14. The bottoms of the two first connecting pipes 14 are connected to the inlet pipe 15. The left and right side walls inside the device box 11 are fixedly connected to the inclined plates 16. The bottom of the device box 11 is fixedly connected to the guide plate 17. Each guide plate 17 is located on the front side between every two inlet pipes 15. The top of the cable tray 6 is equipped with a double suction pump 20. The rear side walls of the two first connecting pipes 14 are connected. A conveyor box 18 is connected to the device box 11. A shovel plate 19 is fixedly connected to the rear interior of the device box 11. The bottom of the conveyor box 18 is connected to the top of the device box 18. The left and right input ends of the double suction pump 20 are fixedly connected to the first transfer pipes 21. The bottom ends of the two first transfer pipes 21 are connected to the transition pipes 22 through the interior of the bridge frame 6. As the device box 11 rotates with the bridge frame 6, the sludge is guided towards the center by the inclined plate 16 inside the device box 11. The guide plate 17 further guides the sludge into the inlet pipe 15. The sludge entering the inlet pipe 15 enters the interior of the first connecting pipe 14.

[0022] In addition, when the device is driven in the reverse direction, the shovel plate 19 on the rear side wall of the device box 11 shovels up the impurities that have not been sucked up by the sewage inlet pipe 15. After the impurities are shoveled up by the shovel plate 19, they are sucked into the interior of the first connecting pipe 14 by the conveying box 18 on the rear side wall that runs through the top.

[0023] like Figure 1 - Figure 6 As shown, the bottom ends of the two transition pipes 22 are connected to the top of the first connecting pipe 14. The rear side wall of the bridge 6 is fixedly connected to the first support plate 23. The output end of the double suction pump 20 is fixedly connected to the second connecting pipe 24. The bottom of the second connecting pipe 24 is fixedly connected to the upper side wall of the first support plate 23. The left end of the second connecting pipe 24 is connected to the drain pipe 25. The bottom end of the drain pipe 25 is located inside the sludge collection tank 2. Before being sucked into the first connecting pipe 14 through the inlet pipe 15 and the conveying box 18, the double suction pump 20 is started. The suction force generated by the double suction pump 20 will be transported into the first connecting pipe 14 through the first transfer pipe 21 and the transition pipe 22. The impurities in the inlet pipe 15 and the conveying box 18 will be sucked in through the first connecting pipe 14 and then sucked into the double suction pump 20 through the top transition pipe 22 and the first transfer pipe 21. The sludge is then pressurized by the double suction pump 20 and transported to the sewage pipe 25 through the second connecting pipe 24, and finally discharged into the sludge collection tank 2 to complete the collection.

[0024] like Figure 1 - Figure 4As shown, a second fixing ring 26 is fixedly connected to the outer side of the top of the support column 12. Push plates 27 are fixedly connected to the outer side of the second fixing ring 26. Connecting blocks 28 are fixedly connected to the other side of the two push plates 27. Slider blocks 29 are fixedly connected inside the two connecting blocks 28. The two sliders 29 are slidably connected inside the slide groove 3. The push plates 27 connected by the second fixing ring 26 at the top of the support column 12 rotate synchronously with the bridge frame. The sliders 29 inside the push plates 27 slide in the slide groove 3 at the top of the treatment tank 1, forming a double guide with the universal wheels on the guide rail, ensuring the stability of the equipment rotation process and avoiding deviation.

[0025] Scrapers 30 are fixedly connected inside both connecting blocks 28. The outer walls of the two scrapers 30 are correspondingly set to the inside of the treatment tank 1. By setting the scrapers 30 to correspond to the inside of the treatment tank 1, the scrapers 30 scrape off the impurities sticking to the inner wall of the treatment tank 1 when the device rotates.

[0026] like Figure 1 - Figure 10 As shown, each of the bottom walls of the treatment tank 1 has a placement slot 31, and each placement slot 31 has an anti-slip cover 32 at its top. A second connecting plate 33 is fixedly connected to the rear side wall of the treatment tank 1, and a gas storage tank 34 is fixedly connected to the rear side wall of the second connecting plate 33. The gas storage tank 34 is fixed to the rear side wall of the treatment tank 1 by the second connecting plate 33. A second support plate 35 is fixedly connected to the rear side wall of the treatment tank 1, and an air pump 36 is installed at the top of the second support plate 35. The air pump 36 is supported by the second support plate 35. The output end of the air pump 36 is fixedly connected to a 37, and the top end of the 37 is connected to the right side wall of the gas storage tank 34. After the air pump 36 is started, the compressed air generated by the air pump 36 is delivered to the gas storage tank 34 fixed by the second connecting plate 33 through the air delivery pipe 37 at the output end. The gas storage tank 34 can stabilize the air pressure and ensure a continuous and uniform gas supply.

[0027] A second transfer pipe 38 is connected to the left side wall of the air storage tank 34. The other end of the second transfer pipe 38 is connected to a conveying pipe 39. Branch pipes 40 are connected to the left side wall of each conveying pipe 39. A nozzle 41 is connected to the top of each branch pipe 40. The outer side of each nozzle 41 is located inside the placement groove 31. Compressed air stored in the air storage tank 34 enters the conveying pipe 39 through the second transfer pipe 38 on the left side wall, and is then distributed to multiple branch pipes 40. The nozzle 41 connected to the top of each branch pipe 40 is placed in the placement groove 31 on the bottom wall of the treatment tank 1. The placement groove 31 provides installation space for the nozzles 41. The anti-slip cover 32 at the top prevents sludge and debris from directly spraying onto the nozzles 41, avoiding blockage and reducing direct friction between the nozzles 41 and the sludge at the bottom of the tank. Compressed air is ejected at high speed through nozzle 41, which disturbs the sediment sludge at the bottom of treatment tank 1. Oil and impurities that float on the wastewater surface by air flotation are guided into the interior of sludge collection tank 2 by the driven push plate 27.

[0028] It should be noted that this utility model is a peripheral drive scraper and suction sludge machine. First, the double suction pump 20 and the air pump 36 are connected to the external power supply and control terminal to supply power and control the device.

[0029] The peripheral drive sludge scraper operates with the universal wheel 9 connected to an external motor and drive unit as its core power source. The drive unit drives the universal wheel to move in a circle along the guide rail 5, thereby pulling the entire equipment, including the bridge, device box, support column and other components, to rotate around the center of the treatment tank 1, so as to realize the continuous scraping and transportation of sludge in the tank. During the equipment rotation, the scraper 30 plays a crucial role in scraping sludge. Because the outer wall of the scraper is aligned with the interior of the treatment tank, it rotates synchronously with the connecting block 28, pushing the sludge deposited on the tank bottom and walls towards the center of the tank. The connecting block and the support column 12 are connected via the second fixing ring 26 and the push plate 27. The rotation of the support column drives the scraper to operate stably, while the slider 29 slides within the groove 3, providing guidance and support for the scraper and ensuring the stability of the sludge scraping process. The sludge pushed to the center of the pool by the scraper will converge under the guidance of the guide plate 17. The guide plate is located at the bottom of the device box 11 and in front of the middle of the inlet pipe 15, which can guide the sludge to the inlet of the inlet pipe. At this time, the double suction pump 20 at the top of the bridge 6 starts, and a negative pressure is formed in the first connecting pipe 14 through the first adapter pipe 21 and the transition pipe 22, which sucks the sludge collected in the inlet pipe into the device box 11. The sludge entering the device box is further aggregated by the inclined plate 16. At the same time, the shovel plate 19 on the rear side of the device box can help clean up the surrounding residual sludge and prevent sludge from accumulating inside the box. The aggregated sludge enters the conveying path of the double suction pump through the conveying box 18. After being pressurized by the double suction pump, it is conveyed to the sewage discharge pipe 25 through the second connecting pipe 24 at the output end, and finally discharged into the sludge collection tank 2 on the outer side of the top of the treatment tank, completing the collection and temporary storage of sludge.

[0030] The core power is provided by the air pump 36 on the second support plate 35. After the air pump is started, compressed air is delivered to the air storage tank 34 fixed on the second connecting plate 33 through the air supply pipe 37 at the output end. The air storage tank stores and stabilizes the gas to ensure the stability and continuity of the subsequent gas supply and provide sufficient power for the subsequent pneumatic cleaning operation. In the gas diversion and injection process, compressed air in the gas storage tank 34 enters the delivery pipe 39 through the second transfer pipe 38 on the left side wall. The delivery pipe diverts the gas to multiple branch pipes 40. The top of each branch pipe is connected to a nozzle 41, and the outside of the nozzle is set in the placement groove 31 on the bottom wall of the treatment tank. The anti-slip cover 32 at the top of the placement groove not only protects the nozzle and prevents sludge from directly covering it and affecting the injection effect, but also guides the airflow direction through its structure. When the equipment performs sludge scraping and suction operations, nozzle 41 simultaneously sprays compressed air, creating airflow disturbance. This disturbance loosens stubborn sludge adhering to the bottom wall of the treatment tank, especially hardened or adhered sludge that is difficult to scrape off directly by scraper 30, making it easier for the scraper to push it to the central area. At the same time, the stirring effect of the airflow in the water reduces secondary sedimentation of sludge during the scraping process, improving the sludge collection efficiency of inlet pipe 15. In conjunction with the existing scraping and suction system, this further enhances the thoroughness of the equipment in cleaning the sludge at the bottom of the treatment tank.
