Manual cleaning is not only labor-intensive and inefficient, but also requires stopping the sedimentation tank during cleaning, severely impacting the continuity of wastewater treatment.

[0003] To address the aforementioned problems, a utility model application with application number CN202321849694.7 discloses an automated sewage tank that is easy to clean. The tank includes a base and is characterized by: a pretreatment tank, a biological treatment tank, and a sedimentation tank mounted on the base; the pretreatment tank being connected to the biological treatment tank via a first pipe, with a filter track installed at the junction of the first pipe and the pretreatment tank; the biological treatment tank being connected to the sedimentation tank via a second pipe, with a filter track installed at the junction of the second pipe, the first pipe, and the biological treatment tank; water pipes and high-pressure nozzles installed in the pretreatment tank, biological treatment tank, and sedimentation tank; and level gauges installed in both the pretreatment tank and the biological treatment tank. This utility model, by installing high-pressure nozzles, improves sewage treatment efficiency and enhances the safety of the working environment; the level gauges monitor the sewage level, providing timely alarms and fault diagnosis; and the two types of tracks facilitate maintenance, efficient cleaning, reduced downtime, and lower maintenance costs.

[0004] In the aforementioned existing technologies, simple spraying devices can only flush away sludge to a certain extent, lacking further collaborative cleaning mechanisms, making it difficult to achieve efficient centralized treatment of sludge. Utility Model Content

[0033] Reference Figure 1 and Figure 2This utility model discloses a high-efficiency cleaning structure for sedimentation tanks in wastewater treatment plants, comprising a tank body 100, a moving component 200, a cleaning component 300, a spray pipe 400, and a sludge scraping component 500. One end of the tank body 100 is equipped with an outlet 121, and the other end with an inlet 111. The tank body 100 is provided with a first sedimentation chamber 110 and a second sedimentation chamber 120. The bottom of the first sedimentation chamber 110 and the bottom of the second sedimentation chamber 120 are connected to the outlet 121 and the second sedimentation chamber 120, respectively. The inlet 111 is connected to the first sedimentation chamber 110. The second sedimentation chamber 120 is provided with an inclined tube settling layer 122. A settling trough 130 is provided at the end of the first sedimentation chamber 110 away from the second sedimentation chamber 120. The moving component 200 is installed in the tank body. At the upper end of the body 100, the moving component 200 can reciprocate along the length direction of the body 100; the cleaning component 300 is fixedly connected to the moving component 200, and the cleaning component 300 fits against the inner walls of both sides of the body 100; the spray pipe 400 is fixedly connected to the moving component 200, and the spray pipe 400 extends along the width direction of the body 100. The spray pipe 400 is provided with multiple high-pressure nozzles 410, and the multiple high-pressure nozzles 410 are arranged along the length direction of the spray pipe 400; the sludge scraping component 500 is fixedly connected to the moving component 200, and the sludge scraping component 500 abuts against the bottom of the body 100; wherein, the moving component 200 can drive the cleaning component 300, the spray pipe 400 and the sludge scraping component 500 to reciprocate at both ends of the first sedimentation chamber 110.

[0034] An embodiment of this utility model provides a high-efficiency cleaning structure for sedimentation tanks in wastewater treatment plants, which has the following two working states:

[0035] Operating State 1: Wastewater enters the first sedimentation chamber 110 from the inlet 111. After initial sedimentation, it flows from the bottom of the first sedimentation chamber 110 into the second sedimentation chamber 120. In the second sedimentation chamber 120, it undergoes further sedimentation through the inclined tube settling layer 122, and the clear water is discharged from the outlet 121. At the same time, the moving component 200 moves back and forth along the length of the tank body 100 at both ends of the first sedimentation chamber 110, synchronously driving the cleaning component 300, the spray pipe 400, and the sludge scraping component 500 to move. At this time, the cleaning component 300 is activated, the sludge scraping component 500 is activated, and the spray pipe 400 is not activated, so as to realize the graded sedimentation of wastewater and the centralized treatment of sludge.

[0036] In the first working state, the "dual sedimentation chamber design" enables graded sedimentation of sewage, improves sedimentation efficiency, and allows sewage treatment and sludge cleaning to be carried out simultaneously without affecting the normal operation of the sedimentation tank. Graded sedimentation improves the degree of sewage purification, while simultaneous cleaning avoids excessive sludge accumulation that affects the sedimentation effect, achieving the effect of treating and maintaining simultaneously.

[0037] Working state two: When the inlet 111 of the sedimentation tank is closed and the moving component 200 moves, the cleaning component 300 first contacts the inner walls on both sides of the tank body 100 to scrape off the attached sludge; then the high-pressure nozzle 410 of the spray pipe 400 sprays high-pressure water jets onto the bottom surface of the tank body 100 to flush away the solidified sludge; finally, the sludge scraping component 500 pushes the dispersed sludge towards the settling trough 130 at the end of the first sedimentation chamber 110 to achieve centralized collection of sludge.

[0038] In the second working state, the sludge inside the pool 100 is thoroughly removed through the step-by-step operation of "scraping-rinsing-pushing", especially the solidified stubborn sludge; the centralized collection in the settling tank 130 facilitates the unified treatment of sludge in the future, reduces sludge residue, and improves the cleanliness of the settling tank.

[0039] In summary, during the movement of the moving component 200, the cleaning component 300 sweeps the sludge on the inner wall, the high-pressure nozzle 410 flushes the sludge on the bottom surface, and finally the sludge scraping component 500 sweeps the dispersed sludge into the settling trough 130 at the bottom end of the first settling chamber 110 for centralized treatment, thus efficiently treating the sludge accumulated in the settling tank.

[0040] In some embodiments, refer to Figure 1 The pool body 100 has a partition wall 140 inside, which divides the interior of the pool body 100 into a first sedimentation chamber 110 and a second sedimentation chamber 120. The outlet 121 is connected to the second sedimentation chamber 120, and the inlet 111 is connected to the first sedimentation chamber 110. The lower end of the partition wall 140 is spaced apart from the bottom of the pool body 100 so that the first sedimentation chamber 110 and the second sedimentation chamber 120 are connected. The inclined tube sedimentation layer 122 is fixed above the second sedimentation chamber 120. Specifically, the partition wall 140 forms a physical barrier within the tank 100, spatially dividing the sewage into two treatment areas. When sewage flows from the first sedimentation chamber 110 into the second sedimentation chamber 120, it must pass through the gap between the lower end of the partition wall 140 and the bottom of the tank 100. This gap creates a certain resistance to the water flow, prolonging the residence time of the sewage in the first sedimentation chamber 110, allowing most of the sludge and floating matter to settle in the first sedimentation chamber 110. After entering the second sedimentation chamber 120, the sewage flows upward through the inclined tube settling layer 122. Inside the inclined tube, the sewage flow rate decreases, and the fine particles settle and adhere to the inner wall of the inclined tube under the action of gravity. After accumulating to a certain extent, they slide down the surface of the inclined tube to the lower guide slope 124, and then flow along the guide slope 124 towards the first sedimentation chamber 110. The clean water continues to rise to the outlet space 123 and is finally discharged from the outlet 121.

[0041] As a further optimization of the above embodiments, refer to Figure 1A guide slope 124 is provided below the inclined tube settling layer 122, and an outlet space 123 is provided above the inclined tube settling layer 122. The outlet 121 is located on one side of the outlet space 123. The guide slope 124 is inclined downward from the end of the second sedimentation chamber 120 away from the first sedimentation chamber 110 towards the end closer to the first sedimentation chamber 110. The inclined guide slope 124 allows the sediment from the inclined tube settling layer 122 to slide down into the first sedimentation chamber 110 for accumulation, facilitating subsequent processing.

[0042] In some embodiments, refer to Figure 1 The moving component 200 includes a guide rail 210, a slider 220, and a first connecting rod 230. Two guide rails 210 are provided, fixedly connected to the upper ends of both sides of the pool body 100, and extending along the length of the pool body 100. The slider 220 is slidably connected to the guide rails 210. Both ends of the first connecting rod 230 are fixedly connected to the two sliders 220 respectively. The structural design of the double guide rails 210 and double sliders 220 ensures the stability of the first connecting rod 230 during movement, preventing tilting or offset. Precise movement along the length of the pool body 100 allows each functional component to cover the entire length range of the first sedimentation chamber 110.

[0043] It is worth mentioning that, referring to Figure 1 The sliding connection between slider 220 and guide rail 210 can be achieved by connecting a drive mechanism such as a gearbox to realize the reciprocating sliding of slider 220 on guide rail 210. Since "how to drive slider 220 to slide on guide rail 210" is a conventional technical means in this field, it will not be described in detail in this technical solution.

[0044] Based on the above embodiments, referring to Figure 1 and Figure 5 The cleaning assembly 300 includes a base 310, a rotating motor 320, and a brush 330. The base 310 is fixed to the end of the first connecting rod 230. The rotating motor 320 is fixed on the base 310, and the output shaft of the rotating motor 320 is fixedly connected to a rotating shaft 321 via a coupling. The brush 330 is arranged vertically, and its upper end is fixedly connected to the rotating shaft 321. The brush 330 abuts against the inner wall of the first sedimentation chamber 110. Two cleaning assemblies 300 are provided, located at opposite ends of the first connecting rod 230. The two cleaning assemblies 300, located at opposite ends of the first connecting rod 230, can simultaneously clean the inner walls of both sides of the tank 100, improving cleaning efficiency. The rotating brush 330 can penetrate deep into the fine irregularities of the inner wall, removing stubborn sludge and keeping the inner wall clean.

[0045] Furthermore, referring to Figure 1The spray pipe 400 and the first connecting rod 230 are arranged in parallel. Multiple first connecting rods 420 are fixedly connected between the spray pipe 400 and the first connecting rod 230. One end of the spray pipe 400 is closed, and the other end is connected to a water inlet hose. The water inlet hose connects the high-pressure water source to the spray pipe 400. The high-pressure water is delivered to each high-pressure nozzle 410 through the internal channel of the spray pipe 400. Since the multiple high-pressure nozzles 410 are arranged along the length of the spray pipe 400, the sprayed high-pressure water flow can cover the entire bottom surface of the pool 100 in the width direction. Driven by the moving component 200, the spray pipe 400 moves to achieve a comprehensive flushing of the bottom surface of the pool 100.

[0046] Preferably, refer to Figure 1 and Figure 2 The high-pressure nozzles 410 located at both ends of the spray pipe 400 are inclined towards the inner wall of the first sedimentation chamber 110, while the remaining high-pressure nozzles 410 are inclined towards the bottom surface of the first sedimentation chamber 110. This allows the two sections of high-pressure nozzles 410 to spray high-pressure water onto the inner walls of both sides of the tank 100, flushing the inner walls of both sides of the tank 100, and working in conjunction with the brush 330 to clean the inner walls of both sides.

[0047] The high-pressure water source mentioned above can be a water tank with a built-in high-pressure water pump. The high-pressure water pump is connected to the inlet hose to deliver high-pressure water through the inlet hose.

[0048] In some embodiments, refer to Figure 3 The sludge scraping assembly 500 includes a second connecting rod 510, a fixed rod 520, a sleeve 530, and a scraper blade 540. The second connecting rod 510 and the first connecting rod 230 are arranged in parallel, and multiple second connecting rods are fixedly connected between the second connecting rod 510 and the first connecting rod 230. The upper end of the fixed rod 520 is fixedly connected to the second connecting rod 510. The upper end of the sleeve 530 is sleeved on the lower end of the fixed rod 520, and the lower end is closed. The sleeve 530 and the fixed rod 520 are slidably fitted together. The tube 530 has a built-in spring 531. One end of the spring 531 is fixedly connected to the lower end of the fixing rod 520, and the other end is fixedly connected to the inner end face of the sleeve 530. The scraper 540 is long and narrow. The scraper 540 and the second connecting rod 510 are arranged in parallel. The upper end of the scraper 540 is fixedly connected to the lower end of the sleeve 530. The lower end of the scraper 540 abuts against the bottom of the first sedimentation chamber 110. The side of the scraper 540 facing the sedimentation tank 130 has a concave arc surface.

[0049] In actual use, the second connecting rod 510 moves under the drive of the first connecting rod 230, and transmits power to the fixed rod 520 through the second connecting rod. The sleeve 530 is fitted on the lower end of the fixed rod 520 and can slide relative to it. The built-in spring 531 generates elastic deformation when the scraper 540 contacts the bottom of the pool, and applies downward pressure to the scraper 540 so that it always keeps in close contact with the bottom of the pool. During the movement, the concave arc surface of the scraper 540 facing the settling tank 130 pushes the sludge into the settling tank 130.

[0050] Specifically, the structure composed of the sleeve 530 and the fixing rod 520 has multiple sets, and the multiple sets of this structure work together to make the elongated scraper 540 bear force evenly.

[0051] Furthermore, referring to Figure 1 The bottom surface of the first sedimentation chamber 110 is inclined. The bottom surface of the first sedimentation chamber 110 is inclined downward from the end near the second sedimentation chamber 120 toward the end away from the second sedimentation chamber 120, that is, inclined toward the end where the sedimentation tank 130 is located. The built-in spring 531 can generate elastic deformation when the scraper 540 contacts the bottom of the pool, and always apply downward pressure to the scraper 540, so that it is always in close contact with the bottom of the first sedimentation chamber 110 and pushes the sludge.

[0052] It is worth mentioning that, referring to Figure 1 Based on the aforementioned structures of the moving component 200, spray pipe 400, cleaning component 300, and sludge scraping component 500, the moving component 200 is located on the rear side of the second sedimentation chamber 120 and the front side of the other side. The spray pipe 400 is located on the front side of the moving component 200, and the sludge scraping component 500 is located on the rear side of the moving component 200. The cleaning component 300 is located between the spray pipe 400 and the sludge scraping component 500. When the moving component 200 moves, the spray pipe 400 on the front side first performs high-pressure flushing on the bottom surface of the tank 100 to disperse the solidified sludge; then the cleaning component 300 in the middle scrapes the inner walls on both sides, causing the attached sludge to fall into the flushed bottom surface; finally, the sludge scraping component 500 on the rear side pushes all the loose sludge (including the flushed and scraped sludge) towards the sedimentation tank 130, forming an orderly cleaning process.

[0053] In some embodiments, refer to Figure 1 and Figure 4 The settling tank 130 has a built-in sludge discharge pipe 131, the end of which is connected to an external pipe. Multiple sludge discharge holes 1311 are provided on the pipe body of the sludge discharge pipe 131. The sludge collected in the settling tank 130 accumulates to the bottom under gravity, enters the pipe through the multiple sludge discharge holes 1311 on the sludge discharge pipe 131, and is then transported to the external pipe through the end of the sludge discharge pipe 131, and finally discharged into the sedimentation tank for further treatment.

[0054] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
