Description

Technical Field

[0001] This invention relates to the field of wastewater and sludge treatment equipment, and more specifically, to an environmentally friendly and energy-saving integrated system for simultaneous treatment of wastewater and sludge. Background Technology

[0002] With the acceleration of urbanization and the expansion of industrial production, wastewater discharge continues to rise, and the sludge generated simultaneously has become a prominent problem in the field of environmental protection. In traditional treatment models, wastewater treatment and sludge disposal are mostly independent processes. Wastewater treatment focuses on removing organic pollutants, nitrogen, phosphorus and other indicators, while sludge needs to undergo subsequent treatments such as concentration, dewatering and stabilization. This not only has the problems of dispersed equipment, large land area and high energy consumption, but also easily leads to secondary pollution due to poor connection between intermediate links. Against this background, the environmental protection and energy-saving integrated system for simultaneous treatment of wastewater and sludge has become a research hotspot. By integrating functional modules such as pretreatment, biological reaction, solid-liquid separation and sludge reduction, it achieves the synergy of "wastewater purification-sludge reduction-energy recovery", significantly reducing system energy consumption and meeting the green treatment needs under the goal of "carbon peaking and carbon neutrality".

[0003] In existing technologies, bar screens, as the core equipment for intercepting suspended impurities in sewage, are prone to a sharp drop in treatment efficiency due to impurity blockage. Specifically, impurity blockage causes bar clogging. Traditional bar screens have fixed bar spacing. When larger particles of impurities become stuck between the bars, or when large amounts of long fibrous impurities, such as hair in domestic sewage or fiber bundles in textile wastewater, become stuck, the cross-sectional area of ​​the water flow is reduced, the head loss increases, and in severe cases, the sewage flow is even blocked, forcing the system to shut down for cleaning. To solve the blockage problem, existing technologies require frequent manual cleaning or auxiliary methods such as high-pressure water washing and mechanical rake cleaning, which increases energy consumption and labor costs, affecting the overall sewage and sludge treatment efficiency. How to invent an environmentally friendly and energy-saving integrated system for simultaneous sewage and sludge treatment to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

[0018] The beneficial effects of this invention are:

[0019] The anti-clogging component continuously adjusts the spacing between the bars during operation, maintaining a pattern of increasing distance and decreasing distance between adjacent bars. When large impurities become stuck between two bars, widening the distance between the bars quickly loosens the impurities, allowing them to pass through more smoothly and reducing their accumulation. This reduces the frequency of manual cleaning, extends the service life of the screen and related equipment, and lowers maintenance costs and downtime. Furthermore, the adaptive adjustment mechanism within the anti-clogging component cleans the stuck impurities sequentially without damaging the structure when they simultaneously become stuck in the gaps between adjacent bars. This provides a quick and effective solution for various types of impurity blockages, further improving the overall anti-clogging effect and increasing the efficiency of subsequent wastewater and sludge treatment.

This ensures the bars can filter impurities continuously and stably, maintains the smooth flow of wastewater, and allows wastewater to continuously and stably enter subsequent treatment units. This ensures that each stage of wastewater treatment proceeds in an orderly manner and improves overall treatment efficiency. Attached Figure Description

A disinfection generator 162 is installed on the outer wall of the disinfection tank 16. The upper side wall of the outer casing 21 is fixedly connected to the outer wall of the collection tank 22. The unloading trough 221 is an inclined trough located on the side of the collection tank 22 near the outer casing 21. The two sprockets 23 are fixed together by a main shaft 231. One end of each sprocket 23 is rotatably connected to the inner wall of the outer casing 21. A drive motor 28 is installed on the outer wall of the outer casing 21 near the sprocket 23. The output end of the drive motor 28 is connected to one of the sprockets 23. The end is fixedly connected, and a fixed rod 241 is fixedly connected between the two chains 24. The outer wall of the fixed rod 241 is rotatably connected to the inner wall of the rotating sleeve 25. A horizontal push plate 251 is fixedly connected to the side wall of the rotating sleeve 25. The two ends of the rotating sleeve 25 have grooves 252. A torsion spring 26 is installed on the inner wall of the groove 252 and sleeved on the outer wall of the fixed rod 241. The two end side walls of the torsion spring 26 are fixedly connected to the groove 252 and the side wall of the chain 24, respectively. A fixed shaft 211 is fixedly connected to the inner wall of the outer shell 21 near the collection tank 22 and is rotatably connected to the inner wall of the rotating shaft 27. A scraper 271 inclined towards the side of the collection tank 22 is fixedly connected to the outer wall of the rotating shaft 27. The two ends of the 11 are provided with through limiting grooves 272. The inner wall of the limiting groove 272 is slidably connected with limiting rods 212 that are fixedly connected to the inner side wall of the outer shell 21 at both ends. The two side walls of the side plate 31 are fixedly connected with ear plates 311. The two ear plates 311 are fixedly connected with sliding rods 33. Several grid bars 32 are initially equidistantly arranged between the two side plates 31. The two side walls of the grid bars 32 are fixedly connected with fixing plates 321. The inner wall of the fixing plate 321 and the outer wall of the sliding rod 33 are slidably connected. Several symmetrical limiting rings 331 are fixedly connected to the outer walls of the sliding rod 33 near both sides of the fixing plate 321. The two outer walls of the fixing plate 321 are fixedly connected with arc bars 322.

[0041] It should be noted that: Wastewater first enters wastewater tank 11 where larger suspended solids are intercepted by the bar screen assembly 2, preventing these larger impurities from entering subsequent treatment units and clogging pipes and equipment. After preliminary filtration by the bar screen assembly 2, the wastewater flows into the equalization tank 12 through wastewater outlet 111. Since wastewater discharge is not uniform and stable, its water quality and quantity fluctuate significantly at different times. The equalization tank 12 stores and mixes the wastewater, regulating its quality and quantity to ensure relative stability of the wastewater entering subsequent treatment stages, guaranteeing the stability of the treatment effect. Then, the wastewater is pumped into the anaerobic tank 13 by submersible pump 121. Anaerobic microorganisms convert large and complex organic molecules in the wastewater into smaller organic molecules, while removing some pollutants and improving the biodegradability of the wastewater. Finally, the wastewater flows into the aerobic tank 14 through the first drain hole 131, where a blower 142 continuously aerates the aerobic tank 14, providing sufficient oxygen for the aerobic microorganisms. The biological system decomposes the remaining organic pollutants in the wastewater, completely converting them into inorganic substances such as carbon dioxide and water, further reducing the content of organic pollutants in the wastewater and achieving the purpose of purifying the wastewater. Afterwards, the wastewater flows into the sedimentation tank 15 through the second drainage hole 141. Under the action of gravity, the suspended matter containing some microbial sludge and other substances is settled, separating the water and sludge. Part of the settled sludge will be returned to the anaerobic tank 13 and aerobic tank 14 through the submersible pump 152 to continuously replenish the microorganisms in the treatment process, ensuring the quantity and activity of the microorganisms to maintain a good treatment effect. The remaining sludge will be discharged from the system for specialized sludge treatment. The supernatant separated from the sedimentation tank 15 will flow into the disinfection tank 16 through the third drainage hole 151. The disinfection generator 162 will produce chlorine dioxide to kill bacteria, viruses, parasites and other pathogenic microorganisms in the water, ensuring that the treated water meets the relevant water quality standards. Afterwards, it will be recycled and reused through the purification pipe 161.

[0042] When wastewater is pretreated by the bar screen assembly 2, large particles of impurities are blocked on one side of the multi-bar screen 32 by the filter assembly 3. The sprocket 23 and chain 24 move under the action of the drive motor 28. During the movement, the rotating sleeve 25 between the chains 24 moves along with it. The push plate 251 at one end contacts the side wall of the bar screen 32 and moves upward, thereby pushing the blocked impurities upward for scraping. When the push plate 251 contacts the end of the scraper 271, the scraper 271 is squeezed and drives the rotating shaft 27 to rotate. During this process, the scraper 271 always sticks to the upper side wall of the push plate 251 and moves continuously towards the end of the push plate 251, causing the push plate 251 to accumulate. Impurities are quickly pushed and lifted into the collection tank 22 on one side by the tilting and rotating action of the scraper 271, so that the impurities are quickly cleaned into the collection tank 22 for collection. Then, the push plate 251 continues to move upward until it contacts the rotating shaft 27. Under the pressure of the rotating shaft 27, the push plate 251 and the rotating sleeve 25 are squeezed and rotated, so that the torsion spring 26 is compressed until the push plate 251 rotates to a vertical state and passes smoothly through the rotating shaft 27 above. At this time, under the action of the torsion spring 26, the push plate 251 returns to the initial parallel state for subsequent cleaning of impurities, thereby continuously cleaning the impurities adhering to the filter assembly 3, avoiding long-term filtration causing blockage and affecting the overall sewage treatment effect;

[0043] Furthermore, four connecting plates 44 are fixed to the side wall of the cylindrical block 41, and two adjacent connecting plates 44 are respectively close to the two ends of the cylindrical block 41. The outer wall of the connecting plate 44 is fixedly connected to the arc block 45. The side of the arc block 45 near the arc strip 322 is provided with an inclined surface 451. Several cylindrical blocks 41 are fixedly connected to each other as a whole by connecting shafts 46. One end of the two outermost cylindrical blocks 41 is fixedly connected to a drive shaft 47. One end of one drive shaft 47 is fixedly connected to a first toothed pulley 48. The anti-blocking motor 49 is installed on one side of the outer wall of the housing 21. The output end of the anti-blocking motor 49 is fixedly connected to one end of the drive shaft 47.

[0044] It should be noted that: while the grille assembly 2 is working, the anti-blocking motor 49 drives the drive shaft 47 to rotate multiple cylindrical blocks 41. During the rotation of the cylindrical blocks 41, the connecting plate 44 on one side drives the arc block 45 to rotate. When the arc block 45 contacts the arc strip 322, the inclined surface 451 of the arc block 45 continues to rotate, squeezing the arc strip 322 and forcing the grille strip 32 to slide to one side until the arc block 45 disengages from the arc strip 322. At this time, the grille strip 32 moves to the very end in one direction, thereby increasing the distance between it and the grille strip 32 on one side. Then, the subsequent arc block 45 re-contacts the arc strip 322, squeezing the grille strip 32 from the other side and pushing it to slide to the other side until it disengages and the grille strip 32 moves to the maximum distance on the other side. During this process... The system expands and contracts the distance between the bar 32, while mirroring the structural components on the multiple cylindrical blocks 41. This allows two bars 32 to either move further apart to increase the distance or move closer together to decrease the distance. Furthermore, when two adjacent bars 32 move closer together, the other two adjacent bars 32 move further apart, creating a pattern of increasing distance and decreasing distance between adjacent bars 32. When large impurities are stuck between two bars 32, increasing the distance between them quickly loosens the impurities, allowing them to pass through more smoothly and reducing their accumulation. This reduces the frequency of manual cleaning, extends the service life of the screen and related equipment, and reduces equipment maintenance costs and downtime.

[0045] Example 2, please refer to Figure 11 and 12 Based on Embodiment 1, in order to prevent impurities from getting stuck in two adjacent gaps at the same time, which would prevent the grid bars 32 from moving, the impurities are cleaned.

[0046] Furthermore, the cylindrical block 41 has four equidistant buffer grooves 411 on its side wall. The inner wall of the buffer groove 411 is fixedly connected to a sliding shaft 42. The outer wall of the sliding shaft 42 is slidably connected to the inner wall of the connecting plate 44. A spring 43 is provided between the outer wall of the connecting plate 44 away from the arc block 45 and the buffer groove 411. The spring 43 is sleeved on the outer wall of the sliding shaft 42. The two end side walls of the spring 43 are fixedly connected to the buffer groove 411 and the outer wall of the connecting plate 44, respectively.

[0047] It should be noted that when impurities are simultaneously trapped in the gaps between adjacent grid bars 32, the grid bar 32 located between the two gaps is squeezed by the impurities on both sides and cannot slide. When the outer arc bar 322 of the grid bar 32 comes into contact with the rotating multiple arc blocks 45, the arc blocks 45 are squeezed under pressure, pushing the spring 43 on one side of the connecting plate 44 to move, causing it to slide towards the inner wall of the buffer groove 411. During this process, the grid bar 32 remains stationary while the position of the arc blocks 45 is adaptively adjusted, avoiding hard contact between the arc blocks 45 and the arc bars 322 that could cause damage and affect subsequent use. At the same time, the grid bar 32 with smaller impurities trapped on one side will move further away under the action of the subsequent arc blocks 45 and arc bars 322. When the distance between the middle and intermediate grid bars 32 increases beyond the diameter of the impurity, the impurity is flushed out by the water flow. Simultaneously, one side of the grid bar 32 closest to the middle is unrestricted, allowing it to move and expand. Subsequently, under the action of the anti-blocking component 4, the distance between it and the other side grid bar 32 is further increased until the impurity is completely removed. This process cleans the impurities in adjacent gaps from one side to the other without damaging the structure. During its operation, it can adapt to different working scenarios and quickly and effectively solve different types of impurity blockages, thereby further improving the overall anti-blocking effect of the structure and improving the overall sewage treatment efficiency.

[0048] Example 3, please refer to Figure 9 and Figure 10 Based on Embodiment 2, in order to prevent soft impurities such as hair from getting tangled and stuck between the grid bars 32;

[0049] Furthermore, multiple cutting components 5 are installed between the two sets of anti-blocking components 4. Each cutting component 5 includes an adjusting shaft 51 and a blade 52. Multiple blades 52 are fixedly connected to the outer wall of the adjusting shaft 51. Each blade 52 is located at the midpoint between the two side plates 31. The two end side walls of the adjusting shaft 51 are rotatably connected to the outer wall of the outer shell 21. The two end ends of the adjusting shaft 51 are fixedly connected to second toothed pulleys 53. A toothed belt 6 is provided between the second toothed pulley 53 and the first toothed pulley 48, as well as between the two second toothed pulleys 53.

[0050] It should be noted that the cutting component 5 rotates in cooperation with the toothed belt 6 and multiple toothed pulleys. During the rotation, the blades 52 on its outer wall continuously extend into the gaps between the grid bars 32 and rotate. During the rotation, it cuts off impurities such as hair that are wrapped around and hanging between the two grid bars 32, preventing the impurities from entangled and accumulating, thus reducing the cross-sectional area between the grid bars 32. By cutting the impurities in a timely manner, it prevents them from entangled and accumulating in large quantities, ensuring the continuous and stable operation of the grid bars 32 in filtering impurities, maintaining the smooth passage of sewage, and allowing sewage to continuously and stably enter the subsequent treatment units. This ensures that each stage of sewage treatment proceeds in an orderly manner, improving the overall treatment efficiency. At the same time, if the impurities are not cut off, they may become entangled on the pump impeller as the sewage enters the subsequent treatment equipment, causing the impeller to operate unbalancedly, accelerating impeller wear, and possibly clogging pipes and affecting the normal aeration of the aerator. Cutting the hair can reduce the adverse effects of hair on these devices and extend the service life of the equipment.

[0051] 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. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
