Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sludge reduction treatment device for sedimentation tanks in wastewater treatment plants. Background Technology

[0002] With the acceleration of urbanization and rapid industrial development, wastewater discharge is increasing daily, making wastewater treatment a crucial link in protecting the environment and achieving sustainable water resource utilization. Wastewater treatment equipment, as the core carrier of wastewater treatment, directly affects the effectiveness and cost of wastewater treatment.

[0003] Currently, there are many types of wastewater treatment equipment on the market, covering various methods such as physical treatment, chemical treatment, and biological treatment. Among them, solid-liquid separation equipment plays an important role in wastewater treatment, effectively separating solid impurities from liquids in wastewater and providing favorable conditions for subsequent advanced treatment.

[0004] Dewatering is a crucial step in sludge treatment. However, existing wastewater treatment equipment has limited dewatering capacity, making it difficult to reduce the sludge's moisture content to an ideal level. Even after initial filtration, the sludge still contains a large amount of water and is bulky, posing significant challenges to subsequent transportation and disposal. High-moisture sludge not only increases transportation costs but also consumes more energy and resources during landfill or incineration, potentially causing secondary pollution. Furthermore, the flowability and uniformity of the sludge are critical to treatment effectiveness. However, existing wastewater treatment equipment has design flaws in its sludge flow channels, making it prone to sludge blockage. Sludge easily accumulates at filter pipe connections, leading to blockages and affecting normal sludge flow and treatment efficiency. Once blockage occurs, manual cleaning is required, increasing workload and potentially causing equipment downtime, disrupting the entire wastewater treatment system. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sludge reduction treatment device for sedimentation tanks in wastewater treatment plants, which solves the problems mentioned in the background art.

[0006] The solution to the above-mentioned technical problems provided by this utility model is as follows: A sludge reduction treatment device for sedimentation tanks in wastewater treatment plants, comprising: A separation tube has an inner tube inside, and a liquid collection chamber is formed between the separation tube and the inner tube; The horizontally laid filter tubes are nested inside the inner tube and are used to filter sewage and discharge the filtrate to the collection chamber. The grate at the bottom of the inner tube is used to guide the filtrate seeping from the filter tube into the collection chamber; At least one shrink tube connected to the end of the filter tube is used to squeeze the sludge to improve dewatering efficiency; The discharge tube is connected to the filter tube via the contraction tube; A drain pipe located at the end of the separation tube is connected to the collection chamber to discharge the filtrate.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the separation tube is laid horizontally, and the inner tube is fixed to the top of the inner wall of the separation tube.

[0009] The beneficial effects of adopting the above-mentioned further solutions are: This layout provides a stable and rational framework for the entire equipment. The horizontal laying of the separation pipes makes the equipment easier to install and arrange in space, allowing it to better adapt to different site environments. The inner pipes are fixed to the top of the inner wall of the separation pipes, providing a solid installation foundation for the filter pipes and other related components. This ensures the stability of the entire internal filtration and separation system, facilitating solid-liquid separation of wastewater within the equipment according to the predetermined process. It reduces problems such as decreased treatment efficiency or equipment failure caused by structural instability, thus improving the reliability and stability of equipment operation.

[0010] Furthermore, the shrink tube is located between the filter tube and the drain tube, or at the connection point of adjacent filter tubes.

[0011] The beneficial effects of adopting the above-mentioned further solutions are: When the shrinkage pipe is located between the filter pipe and the discharge pipe, it can further compress and dewater the sludge after preliminary filtration, minimizing its moisture content and volume before it is discharged from the equipment, thus facilitating subsequent transportation and disposal. When located at the connection point of adjacent filter pipes, the shrinkage pipe serves as a connector and transition, while also compressing the sludge at the connection point. This ensures the continuity of the entire sludge flow channel and the consistency of the treatment effect, preventing sludge blockage or uneven treatment, and improving the overall sludge processing capacity and efficiency of the equipment.

[0012] Furthermore, a pressure tube is threadedly connected to the end of the separation tube for axially pressing the filter tube system.

[0013] The beneficial effects of adopting the above-mentioned further solutions are: The threaded connection of the pressure pipe allows for convenient adjustment of the compression level of the filter tube system. During equipment operation, axial compression of the filter tube system enhances the tightness of the connection between the filter tube and components such as the inner tube and contraction tube, preventing leakage of sewage and sludge during treatment and ensuring effective solid-liquid separation. Simultaneously, this compression action reduces vibration and noise during equipment operation, improving equipment stability and service life. Furthermore, the threaded connection facilitates the installation and disassembly of the pressure pipe, enabling quick operation during equipment maintenance and repair, reducing maintenance costs and time.

[0014] Furthermore, the gap between the drain tube, the shrink tube and the inner tube is filled with pads, and is fixed by clamping the pressure tube and the filter tube.

[0015] The beneficial effects of adopting the above-mentioned further solutions are: The spacers, filling the gaps between the drain pipe, contraction pipe, and inner pipe, serve a sealing and securing function. On one hand, they prevent sewage and sludge from leaking out of these gaps, ensuring the cleanliness of the equipment's interior and the stability of the treatment environment, thus avoiding pollution of the surrounding environment. On the other hand, by clamping and fixing the spacers to the pressure pipe and filter pipe, the stability of the entire equipment structure is enhanced, making the connections between components more secure. This reduces the risk of loosening or displacement of components due to vibration and impact during equipment operation, improving the reliability and safety of the equipment.

[0016] Furthermore, it also includes at least one connecting pipe, the two ends of which are connected to the filter pipe and the drain pipe respectively through shrink tubes, for extending the length of the equipment.

[0017] The beneficial effects of adopting the above-mentioned further solutions are: The connecting pipes enhance the equipment's flexibility and adaptability. Depending on the scale of wastewater treatment and site conditions, the length of the equipment can be flexibly adjusted by increasing or decreasing the number of connecting pipes to meet various practical needs. This eliminates the need to redesign and manufacture the entire equipment based on changes in treatment capacity, significantly reducing costs and manufacturing cycles. Furthermore, this modular design facilitates transportation and installation, improving the equipment's versatility and market competitiveness.

[0018] Furthermore, the pad is made of an elastic material and is adapted to the outer contour of the drain pipe and the shrink pipe.

[0019] The beneficial effects of adopting the above-mentioned further solutions are: The pads, made of elastic materials, possess excellent cushioning and shock absorption properties. During equipment operation, they absorb and disperse stress generated by vibration and impact between components, reducing wear and damage and extending equipment lifespan. Furthermore, because the pads conform to the outer contours of drain and contraction pipes, they better fill gaps, providing a tighter seal and preventing sewage and sludge leakage. Simultaneously, the elastic pads can accommodate thermal expansion and contraction of components and installation errors to a certain extent, ensuring normal operation of the equipment under various working conditions and improving its stability and reliability.

[0020] This utility model provides a sludge reduction treatment device for sedimentation tanks in wastewater treatment plants. It has the following beneficial effects: The equipment features a filter tube nested within an inner tube. After wastewater enters the filter tube, it performs filtration, quickly separating solid sludge and liquid from the wastewater. A grate at the bottom of the inner tube allows filtrate seeping from the filter tube to be promptly channeled into a collection chamber, ensuring a continuous and efficient solid-liquid separation process. This significantly reduces sludge treatment time and improves overall treatment efficiency.

[0021] At least one shrinkage tube is connected to the end of the filter tube. As the sludge flows through the filter tube and enters the shrinkage tube, the space in the shrinkage tube gradually narrows, creating a squeezing effect on the sludge. This squeezing force can disrupt the cellular structure of the sludge, converting the bound water in the sludge into free water, thereby further improving the dewatering efficiency of the sludge and reducing its moisture content.

[0022] The equipment includes at least one connecting pipe section, with its two ends connected to the filter pipe and the waste discharge pipe respectively via shrink tubes, or located at the connection point of adjacent filter pipes. By increasing or decreasing the number of connecting pipes, the length of the equipment can be flexibly expanded according to actual treatment needs and site conditions. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows: Example 1 A sludge reduction treatment device for sedimentation tanks in wastewater treatment plants, comprising: The separation tube 1 has an inner tube 103 inside, and a liquid collection chamber 102 is formed between the separation tube 1 and the inner tube 103. The horizontally laid filter tube 2 is nested inside the inner tube 103 and is used to filter sewage and discharge the filtrate to the collection chamber 102. The grate 106 located at the bottom of the inner tube 103 is used to guide the filtrate seeping from the filter tube 2 into the collection chamber 102. At least one section of shrink tube 203 connected to the end of filter tube 2 is used to squeeze sludge to improve dewatering efficiency; The drain pipe 201 is connected to the filter pipe 2 via the shrink pipe 203; The drain pipe 101 located at the end of the separation pipe 1 is connected to the collection chamber 102 to discharge the filtrate.

[0028] Example 2 To further improve the stability, sealing performance, operational reliability, and ease of use of the equipment structure, for example, such as Figures 1 to 4 As shown, this utility model also includes: The separation pipe 1 is laid horizontally, with the inner pipe 103 fixed to the top of its inner wall. This layout provides a stable and reasonable framework for the entire equipment. The horizontal laying of the separation pipe 1 makes the equipment easier to install and arrange in space, better adapting to different site environments. The inner pipe 103, fixed to the top of the inner wall of the separation pipe 1, provides a stable installation foundation for the filter pipe 2 and other related components, ensuring the stability of the entire internal filtration and separation system. This facilitates solid-liquid separation of wastewater within the equipment according to a predetermined process, reducing problems such as decreased treatment efficiency or equipment failure due to structural instability, and improving the reliability and stability of equipment operation. A pressure pipe 104 is threadedly connected to the end of the separation pipe 1 for axially compressing the filter pipe 2 system. The pressure of the filter pipe 2 system can be easily adjusted through the threaded connection of the pressure pipe 104. During equipment operation, the axial compression of the filter pipe 2 system enhances the tightness of the connection between the filter pipe 2 and components such as the inner pipe 103 and the contraction pipe 203, preventing leakage of wastewater and sludge during treatment and ensuring the effectiveness of solid-liquid separation. Meanwhile, this clamping action can also reduce vibration and noise during equipment operation, improving equipment stability and service life. Furthermore, the threaded connection facilitates the installation and disassembly of the pressure pipe 104, enabling quick operation during equipment maintenance and repair, reducing maintenance costs and time. The gaps between the drain pipe 201, the contraction pipe 203, and the inner pipe 103 are filled with gaskets 105, which are clamped and fixed to the filter pipe 2 by the pressure pipe 104. The gaskets 105, filling the gaps between the drain pipe 201, the contraction pipe 203, and the inner pipe 103, serve a sealing and fixing function. On one hand, it prevents sewage and sludge from leaking out of these gaps, ensuring the cleanliness of the equipment's interior and the stability of the treatment environment, avoiding pollution to the surrounding environment. On the other hand, clamping and fixing the gaskets 105 to the filter pipe 2 by the pressure pipe 104 enhances the stability of the entire equipment structure, making the connections between components more secure, reducing loosening or displacement of components due to vibration and impact during equipment operation, and improving the reliability and safety of the equipment. The pad 105 is made of elastic material and conforms to the outer contours of the drain pipe 201 and the contraction pipe 203. Made of elastic material, the pad 105 provides excellent cushioning and shock absorption. During equipment operation, it absorbs and disperses stress generated by vibration and impact between components, reducing wear and damage and extending the equipment's service life. Furthermore, because the pad 105 conforms to the outer contours of the drain pipe 201 and the contraction pipe 203, it better fills gaps, providing a tighter seal and preventing sewage and sludge leakage. Simultaneously, the elastic pad 105 can also accommodate thermal expansion and contraction of components and installation errors to a certain extent, ensuring normal operation of the equipment under various working conditions and improving its stability and reliability.

[0029] Example 3 To enhance the flexibility, adaptability, and sludge treatment capacity of the equipment, and to meet diverse wastewater treatment needs, for example, such as Figures 1 to 4 As shown, this utility model also includes: The system also includes at least one connecting pipe 202, whose two ends are connected to the filter pipe 2 and the solid waste discharge pipe 201 respectively via shrink pipes 203, for extending the equipment length. The connecting pipe 202 makes the equipment more flexible and adaptable. Depending on different wastewater treatment scales and site conditions, the length of the equipment can be flexibly adjusted by increasing or decreasing the number of connecting pipes 202 to meet various practical needs. There is no need to redesign and manufacture the entire equipment due to changes in treatment capacity, greatly reducing equipment costs and manufacturing cycles. At the same time, this modular design facilitates equipment transportation and installation, improving the equipment's versatility and market competitiveness. The shrink pipe 203 is located between the filter pipe 2 and the solid waste discharge pipe 201, or at the connection point of adjacent filter pipes 2. When the shrink pipe 203 is located between the filter pipe 2 and the solid waste discharge pipe 201, it can further squeeze and dewater the sludge after preliminary filtration by the filter pipe 2, minimizing its moisture content and volume before the sludge is discharged from the equipment, facilitating subsequent transportation and disposal. When located at the connection point of adjacent filter tubes 2, the contraction tube 203 can serve as a connection and transition, while also squeezing the sludge at the connection point to ensure the continuity of the entire sludge flow channel and the consistency of the treatment effect, avoiding sludge blockage or uneven treatment, and improving the overall sludge treatment capacity and efficiency of the equipment.

[0030] Working principle: The device is installed at the front end of the sedimentation tank. Wastewater enters filter pipe 2. Due to the filtration function of filter pipe 2, water in the wastewater will seep out through filter pipe 2. The seeping filtrate enters the collection chamber 102 formed between separation pipe 1 and inner pipe 103 through the grate 106 at the bottom of inner pipe 103. This process utilizes the filtration characteristics of filter pipe 2 to initially separate solid sludge and liquid in wastewater, allowing the liquid to enter the collection chamber 102 while the sludge remains in filter pipe 2.

[0031] At least one shrink tube 203 is connected to the end of the filter tube 2. When the sludge flows through the filter tube 2 with the sewage and reaches the shrink tube 203, the shrink tube 203 will squeeze the sludge. This squeezing action can improve the dewatering efficiency of the sludge, squeeze out more water from the sludge, and further reduce the water content in the sludge.

[0032] The dewatered sludge is discharged from the equipment through the solids discharge pipe 201, achieving the separation and discharge of solid sludge. At the same time, the filtrate in the liquid collection chamber 102 is discharged to the sedimentation tank through the liquid discharge pipe 101 located at the end of the separation pipe 1, achieving the purpose of sludge reduction and filtrate separation.

[0033] In addition, the separation pipe 1 is laid horizontally and the inner pipe 103 is fixed to the top of the inner wall of the separation pipe 1. The pressure pipe 104 threaded at the end of the separation pipe 1 can axially press the filter pipe 2 system to ensure the stability and sealing of the entire filter pipe 2 system. The gap between the discharge pipe 201, the shrink pipe 203 and the inner pipe 103 is filled with a pad 105 made of elastic material, which is clamped and fixed to the filter pipe 2 by the pressure pipe 104. The pad 105 is adapted to the outer contour of the discharge pipe 201 and the shrink pipe 203, and plays a role in buffering and fixing to prevent the components from loosening. The length of the equipment can also be extended by at least one connecting pipe 202, which uses the shrink pipes 203 at both ends to connect the filter pipe 2 and the discharge pipe 201 respectively, or is set at the connection of adjacent filter pipes 2 to adapt to different processing needs and site conditions.
