[0024] See also Figure 1-5 As shown, the utility model relates to a multi-stage cylindrical inclined bucket sedimentation tank, including a mixing tank, a water passage 13, two inclined bucket sedimentation tank components, a sewage inlet pipe 10, and a sewage drainage pipe 102, wherein the sewage inlet pipe 10 is connected to the mixing tank, and the sewage drainage pipe 102 is connected to the first inclined bucket sedimentation tank component; each inclined bucket sedimentation tank group includes an inclined bucket sedimentation tank 42, a working platform bracket is arranged above the inclined bucket sedimentation tank 42, and a cylinder mounting bracket 27 is arranged at the bottom of the working platform bracket, and the cylinder 3 can be detachably mounted inside the cylinder mounting bracket 27, wherein The mixing tank is connected with the cylinder 3 through the water passage 13 (a gap connected with the water passage 13 is provided on one side of the cylinder 3), and is connected with the inclined bucket sedimentation tank 42 through the cylinder 3; a scraper spindle 28 is also movably mounted in the cylinder mounting bracket 27, and the scraper spindle 28 extends into the inclined bucket sedimentation tank 42 and is installed with a scraper assembly; a scraper drive assembly is also provided on the working platform bracket, wherein the scraper drive assembly and the scraper spindle 28 are detachably driven, and when the scraper drive assembly is separated from the scraper spindle 28, it no longer hinders the removal of the cylinder 3.

[0025] At the same time, the rapidly flowing sewage enters from the top of the cylinder 3 in the center area of ​​the inclined bucket sedimentation tank 42, and after the buffer pressure is released, the pressure is released again from the bottom of the cylinder 3 to the outside and dissipated to the surroundings, so that the sludge is precipitated downward from the sewage by its own gravity.

[0026] Furthermore, the scraper assembly includes a transverse scraper blade 29 connected to the scraper main shaft 28, and the two ends of the transverse scraper blade 29 are soft rubber plates 210. The design of the transverse scraper blade 29 can increase the contact area with the bottom of the inclined bucket sedimentation tank 42, so as to scrape the sludge more effectively. The soft rubber plate 210 has a certain flexibility and can better adapt to the unevenness or slight deformation that may exist at the bottom of the inclined bucket sedimentation tank 42, ensuring the consistency of the scraping effect. Compared with a hard scraper blade, the soft rubber plate 210 can reduce the friction with the bottom of the inclined bucket sedimentation tank 42 during the scraping process, reduce wear and extend the service life. The soft rubber plate 210 will not scratch or damage the bottom of the inclined bucket sedimentation tank 42 when scraping mud, which helps to protect the equipment.

[0027] Furthermore, in this specific embodiment, the mixing tank includes a primary mixing tank 11 and a secondary mixing tank 12. The primary mixing tank 11 is connected to a sewage inlet pipe 10, and the sewage enters the secondary mixing tank 12 from an opening on one side of the bottom of the primary mixing tank 11. The secondary mixing tank 12 is connected to the cylinder 3 through a water passage 13. At the same time, stirring components are provided in both the primary mixing tank 11 and the secondary mixing tank 12.

[0028] By setting up the primary stirring tank 11 and the secondary stirring tank 12, it can be ensured that the sewage is fully mixed and pre-treated before entering the sedimentation tank. This helps to remove large particles of impurities in the sewage and provide better conditions for the subsequent sedimentation process. The sewage enters the secondary stirring tank 12 from the opening on one side of the bottom of the primary stirring tank 11. This design can ensure that the sewage is further stirred and mixed during the flow process, thereby improving the pretreatment effect. Stirring components are provided in the primary stirring tank 11 and the secondary stirring tank 12. These components can effectively stir the sewage, promote the uniform distribution of impurities in the sewage, and help the subsequent sedimentation and filtration process.

[0029] Further, the stirring assembly includes a stirring bracket 111, a stirring motor 112, and a stirring rod 113, wherein the stirring motor 112 is arranged on the primary stirring tank 11 or the secondary stirring tank 12 through the stirring bracket 111, and the output end of the stirring motor 112 drives the stirring rod 113 and extends into the primary stirring tank 11 or the secondary stirring tank 12. The stirring bracket 111 serves as a supporting structure to ensure the stable installation of the stirring motor 112 and the stirring rod 113. This stability is essential for the long-term operation and efficient operation of the stirring assembly. The stirring motor 112 serves as a power source, and its output end drives the stirring rod 113 to rotate. Selecting a suitable stirring motor 112 can ensure that the stirring rod 113 has sufficient stirring force, thereby achieving effective mixing of the sewage. The stirring rod 113 extends into the primary stirring tank 11 or the secondary stirring tank 12, and through its rotational motion, the sewage can be effectively stirred, the impurities in the sewage are promoted to be evenly distributed, and the pretreatment effect is improved.

[0030] Furthermore, a first-level mud discharge pipe 101 is also provided at the bottom of one side of the first-level stirring tank 11. In the process of sewage stirring and pretreatment in the first-level stirring tank 11, some sediment or sludge will be generated. By providing the first-level mud discharge pipe 101, these sediments can be discharged in time to prevent them from accumulating in the stirring tank and affecting the stirring effect and subsequent sedimentation process. Timely mud discharge helps to maintain the cleanliness of the sewage in the stirring tank, making the subsequent stirring and pretreatment more effective. This helps to improve the treatment efficiency of the entire sedimentation system and ensure that the sewage is better treated.

[0031] Furthermore, the working platform support includes a ground support 21 and working fences 22 mounted on both sides of the ground support 21, and the bottom of the center of the ground support 21 is mounted with a cylindrical mounting bracket 27. The ground support 21 is the main load-bearing structure of the working platform support, and its design should ensure sufficient stability and load-bearing capacity. By being assembled with the cylindrical mounting bracket 27, the entire working platform support can stably support the workers and their operating equipment to reduce accidental risks. The working fences 22 on both sides not only provide protection for the workers to prevent them from accidentally falling, but also limit the working area to ensure the safety of the operation process. The height and strength of the fence should be designed according to actual needs to meet safety standards.

[0032] The design of the work platform support should take into account the convenience of the staff. For example, the height and area of ​​the platform should be moderate, which is convenient for the staff to inspect, maintain and operate the equipment. At the same time, the surface of the platform can be made of non-slip material to improve work safety.

[0033] Furthermore, the scraper drive assembly includes a scraper motor 26 and a motor separation bracket 25. The motor separation bracket 25 is movably mounted on the working fence 22. The scraper motor 26 is mounted on the motor separation bracket 25, and the output end of the scraper motor 26 is detachably driven by the scraper main shaft 28 through the connecting sleeve 1121. The motor separation bracket 25 rotates around the working fence 22 and separates the connecting sleeve 1121 of the scraper motor 26 from the scraper main shaft 28.

[0034] The output end of the scraper motor 26 is detachably driven by the scraper main shaft 28 through the connecting sleeve 1121. This design makes the connection and separation between the scraper motor 26 and the scraper main shaft 28 simple and quick. When the scraper motor 26 or the scraper main shaft 28 needs to be maintained or replaced, it is only necessary to unfasten the connecting sleeve 1121, which greatly improves the work efficiency.

[0035] The motor separation bracket 25 is movably mounted on the working fence 22 and can rotate around the working fence 22. This allows the scraper motor 26 to be easily moved to a suitable position, which is convenient for operators to install, debug and maintain. Through the combination of the motor separation bracket 25 and the working fence 22, the scraper motor 26 is firmly supported, reducing safety risks during operation. At the same time, this design also helps to keep the working area clean and orderly, further improving the safety of operation.

[0036] Furthermore, the scraper drive assembly also includes a rotating drive bracket 23, which is fixed on one side of the working fence 22, and the rotating drive bracket 23 is provided with a fixed plate 24, wherein the upper end of the fixed plate 24 is provided with a first winding wheel 213, wherein the lower end of the fixed plate 24 is provided with a second winding wheel 212, and one side of the second winding wheel 212 is also provided with a crank 211, wherein a pulling wire 214 is wound on the second winding wheel 212, and the pulling wire 214 bypasses the second winding wheel 212 and is connected to the motor separation bracket 25, that is, by hand-cranking the crank 211, the motor separation bracket 25 can be rotated and pulled upward, thereby realizing the separation of the output end of the scraper motor 26 from the scraper main shaft 28, and at the same time, when the scraper drive assembly is separated from the scraper main shaft 28, it no longer hinders the removal of the cylinder 3.

[0037] By hand-cranking the crank handle 211, the retraction and extension of the pulling wire 214 can be easily controlled, thereby realizing the up and down rotation of the motor separation bracket 25. This design avoids the use of complex mechanical or electric devices, making the operation simpler and more intuitive. By pulling the motor separation bracket 25 upward with the pulling wire 214, the output end of the scraper motor 26 can be quickly separated from the scraper main shaft 28. This greatly improves the efficiency of maintenance and replacement of parts and reduces downtime. When the scraper drive assembly is separated from the scraper main shaft 28, it no longer hinders the removal of the cylinder 3. This optimizes the spatial layout of the equipment, making the entire sedimentation system more compact and efficient. Through the design of the rotating drive bracket 23 and the pulling wire 214, the operator can operate at a safe distance, reducing the safety risks that may be caused by direct contact with the equipment.

[0038] Furthermore, there are two inclined bucket sedimentation tank assemblies, including a first inclined bucket sedimentation tank assembly and a second inclined bucket sedimentation tank assembly. The first inclined bucket sedimentation tank assembly is connected to the second inclined bucket sedimentation tank assembly through a first sewage overflow channel 141, and the second inclined bucket sedimentation tank assembly is connected to the sewage drain pipe 102 through a second sewage overflow channel 15.

[0039] By setting up two inclined bucket sedimentation tank assemblies, the overall processing capacity of the system is improved. Each inclined bucket sedimentation tank assembly can independently perform sewage sedimentation treatment, thereby speeding up the processing speed and reducing the residence time of sewage in the treatment system. The first inclined bucket sedimentation tank assembly is connected to the second inclined bucket sedimentation tank assembly through the first sewage overflow channel 141, which means that when one inclined bucket sedimentation tank assembly is close to full load, the excess sewage can automatically flow into the other inclined bucket sedimentation tank assembly, ensuring the continuity of sewage treatment. The second inclined bucket sedimentation tank assembly is connected to the sewage drain pipe 102 through the second sewage overflow channel 15, ensuring the quality of sewage after two sedimentation treatments. This design helps to remove more suspended matter and pollutants and improve the quality of effluent.

[0040] Furthermore, the first sewage overflow channel 141 is a T-shaped structure, and the first sewage overflow channel 141 includes a horizontal overflow channel 141 and a sewage water passage channel 142 placed vertically relative to the overflow channel 141, wherein the top edge of the overflow channel 141 is a toothed structure 1412, and the overflow channel 141 is connected to the cylinder 3 in the second inclined bucket sedimentation tank assembly through the sewage water passage 142; the second sewage overflow channel 15 is arranged on the other side of the second inclined bucket sedimentation tank assembly, and the top edge of the second sewage overflow channel 15 is also a toothed structure 1412.

[0041] The design of the horizontal overflow channel 141 allows sewage to accumulate here and reach a certain water level, and then overflow through the edge of the toothed structure 1412. This design helps to control the flow rate and flow of sewage, ensuring that the sewage has enough time to settle in the sedimentation tank. The sewage water passage 142 is placed vertically, connecting the overflow channel 141 and the cylinder 3 in the second inclined bucket sedimentation tank assembly. This design ensures that sewage can flow smoothly from the first inclined bucket sedimentation tank assembly to the second inclined bucket sedimentation tank assembly, while avoiding splashing and leakage of sewage during the flow process.

[0042] The tooth-shaped structure 1412 at the top edge of the overflow channel 141 increases the surface area of ​​the sewage, making it easier for the sewage to settle there. At the same time, the tooth-shaped structure 1412 can also effectively prevent the sewage from forming a large water flow when overflowing, which helps to reduce the scouring and disturbance of the sediment by the water flow.

[0043] In addition, a motor separation bracket 25 is provided on the working platform bracket, wherein the scraper motor 26 is installed on the motor separation bracket 25. The motor separation bracket 25 is dug up and lifted by means of a manual crank 211 (not limited, other driving methods can also be used), so that the scraper motor 26 is separated from the scraper main shaft 28. Then, the scraper motor 26 no longer blocks the cylinder 3, and the staff can stand on the working platform bracket, and then take out and replace the PP material cylinder 3 by appropriate means.

[0044] In this specific embodiment, the cylinder 3 is made of PP material. First, the PP material itself has excellent processing properties. Its melt viscosity decreases significantly with the increase of shear speed, which makes it possible to improve its fluidity by increasing the injection pressure and injection speed, thereby optimizing the shrinkage deformation and depression problems of the product. In addition, the processing temperature range of PP is relatively wide, usually between 200 and 300°C, and its thermal stability is good, and the decomposition temperature is as high as 310°C. Secondly, the cylinder 3 made of PP material is light, which means that even if heavy objects are placed in the cylinder, it will not increase its own weight. In addition, the PP material is easy to shape, so cylinders 3 of various shapes and specifications can be manufactured to meet different usage requirements. This cylinder 3 is not only beautiful in appearance, but also strong and durable, with good mechanical properties and not easy to break. Furthermore, the cylinder 3 made of PP material is a green and environmentally friendly material, non-toxic and tasteless, and environmentally friendly. Its chemical resistance is also quite excellent, and it is inert to most acids, alkalis, salts, and oxidants.

[0045] Furthermore, an inclined bucket mud discharge pipe 41 is provided at the bottom of the inclined bucket sedimentation tank to facilitate mud discharge.

[0046] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention.
