Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge dewatering module for wastewater treatment. Background Technology
[0002] In the wastewater treatment industry, sludge dewatering is a crucial step in achieving sludge reduction and harmless treatment. Its core objective is to remove free and interstitial water from the sludge, reducing its volume and moisture content, thus laying the foundation for subsequent sludge transportation, landfilling, or resource utilization. With increasingly stringent environmental regulations on wastewater treatment discharge standards and the trend towards large-scale and intensive development of wastewater treatment plants, traditional decentralized sludge treatment equipment, due to its complex installation, large footprint, and poor adaptability, can no longer meet the needs of modern wastewater treatment scenarios. Sludge dewatering equipment with integrated design, convenient installation, and high space utilization has gradually become the mainstream application in the industry. Among them, the diaphragm filter press, with its stable filtration effect, has become the main form of equipment for sludge dewatering.
[0003] Currently, diaphragm filter presses commonly used for sludge dewatering can achieve basic sludge dewatering functions, but they lack necessary environmental control mechanisms and have obvious technical limitations: these devices do not have dedicated temperature and humidity control devices. During the sludge dewatering process, natural fluctuations in ambient temperature and humidity can cause changes in sludge viscosity, which can easily lead to problems such as filter cloth clogging and sludge adhering to the filter chamber walls. This not only reduces the filtration efficiency and sludge dewatering effect, but also increases the difficulty of equipment cleaning, shortens the service life of filter cloth and filter press components, and cannot adapt to different practical application needs.

[0036] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0037] Example 1:
[0038] like Figures 1-3 As shown, this embodiment provides a sludge dewatering module for wastewater treatment, including a housing 1, a sludge filter press assembly, a monitoring component, a temperature and humidity control system, and an electrical control box 2. The housing 1 includes a module frame 11, a module support 12, and multiple module baffles 13. The module frame 11 is mounted on the module support 12, and the multiple module baffles 13 are correspondingly arranged on the top and multiple sides of the module frame 11. The sludge filter press assembly is located in the middle of the module support 12, and the electrical control box 2 is located on the edge of the module support 12. The monitoring component and the temperature and humidity control system are located inside the module frame 11. The sludge filter press assembly, the monitoring component, and the temperature and humidity control system are connected to the electrical control box 2.
[0039] Specifically, the modular integrated design of the housing 1 provides a stable and unified installation platform for the sludge filter press assembly, monitoring components, temperature and humidity control system, and electrical control box 2, significantly improving the overall structural integrity and space utilization of the equipment. This facilitates rapid installation and flexible adaptation to wastewater treatment scenarios of different scales, solving the problems of dispersed structure and cumbersome installation in traditional diaphragm filter presses. Simultaneously, by integrating the temperature and humidity control system within the modular frame 11, the ambient temperature and humidity during sludge dewatering can be kept constant, effectively avoiding changes in sludge viscosity, filter cloth clogging, and sludge adhesion to the filter chamber caused by temperature and humidity fluctuations in existing technologies. Addressing issues such as filter wall defects significantly improves the stability of filtration efficiency and sludge dewatering, reduces equipment cleaning frequency, and extends the service life of filter cloth and filter press components. Furthermore, the integrated monitoring components allow real-time monitoring of the sludge filter press assembly's structural status during dewatering. Combined with centralized control of the sludge filter press assembly, monitoring components, and temperature and humidity control system via the electrical control box 2, this achieves organic synergy among various functional components, simplifies operation, reduces manual intervention and maintenance costs, and comprehensively promotes the upgrade of sludge dewatering equipment from a single filtration function to an integrated system, meeting the modern wastewater treatment industry's demand for efficient, stable, and convenient treatment equipment. Compared to existing technologies, by integrating the core filtration function with temperature and humidity control, status monitoring, and centralized electrical control, it solves the technical pain points of existing technologies, such as significant environmental influence and insufficient operational stability. It achieves significant improvements in structural compactness, ease of operation, and treatment effect stability, making it more suitable for the large-scale and intensive application needs of modern wastewater treatment scenarios.
[0040] Furthermore, such as Figure 3 and Figure 4As shown, the module support 12 includes a base 14, at least two baffles 15 and multiple height-adjustable support rods 16; the two baffles 15 are arranged in parallel on the base 14, and the sludge filter press assembly is located between the two baffles 15; the multiple support rods 16 are supported below the base 14. The base 14 provides a flat and stable installation foundation for core components such as the sludge filter press assembly and the electrical control box 2. The two parallel baffles 15 can provide lateral restraint and protection for the sludge filter press assembly, effectively preventing displacement or tilting of the assembly due to equipment vibration or load changes during the filtration process, ensuring the sealing performance of the filter chamber and the accuracy of the filtration action. The multiple support rods 16 under the base 14 not only significantly enhance the overall load-bearing capacity and structural stability of the support frame, but also allow for adjustment of the height of the support rods 16 to adapt to different flatness levels of the installation ground, facilitating quick leveling and installation of the equipment. At the same time, this layered support and restraint design makes the installation and maintenance of the sludge filter press assembly more convenient. Combined with the modular integration of the housing 1, it further improves the overall structural compactness and operational reliability of the equipment, and provides a good structural guarantee for the stable operation of the temperature and humidity constant system and monitoring components.
[0041] Furthermore, such as Figure 4 As shown, the baffle 15 includes a connecting rod 17, multiple support rods 18, and two diagonal braces 19. The connecting rod 17 is horizontally arranged and supported on the base 14 by multiple support rods 18. The two ends of the connecting rod 17 are connected to the base 14 by two diagonal braces 19, which not only provides stable multi-point support for the connecting rod 17, effectively dispersing the lateral pressure on the connecting rod 17 and preventing bending deformation after long-term use, but also reserves reasonable maintenance space to facilitate maintenance of the side components of the sludge filter press assembly. The two diagonal braces 19 connecting the two ends of the connecting rod 17 to the base 14 form a stable triangular force-bearing structure, which greatly improves the overall performance of the baffle 15. Its anti-overturning and anti-vibration performance can effectively offset the lateral impact force generated during sludge dewatering, preventing the baffle 15 from shifting or tilting due to uneven force. This multi-component collaborative structural design not only strengthens the structural strength and stability of the baffle 15 itself, but also complements the base 14 and support rod 16 of the modular bracket 12, further ensuring the installation accuracy and operational stability of the sludge dewatering assembly. It creates a good mechanical environment for the stable operation of the temperature and humidity constant system and monitoring components, while simplifying the assembly process of the baffle 15, adapting to the overall modular design concept, and improving the overall reliability and service life of the equipment.
[0042] Furthermore, such as Figure 1As shown, the sludge filter press assembly includes a frame 31, a diaphragm filter assembly 32, a feed plunger pump 33, a press pump assembly 34, and a transport mechanism 35. The frame 31 is mounted on the module bracket 12, providing a stable integrated mounting foundation for each functional component. The diaphragm filter assembly 32 is mounted on the frame 31, and its outlet pipe is connected to the drain pipe on the frame 31 to ensure rapid and leak-free filtrate discharge. The press pump assembly 34 is mounted at one end of the frame 31, and its drive end can withstand... A diaphragm filter assembly 32 is connected to the frame 31 to compress the diaphragm filter assembly 32. A transport mechanism 35 is installed on the frame 31 and located below the diaphragm filter assembly 32. In this embodiment, the transport mechanism 35 has a filter cake transport channel, which is a tubular structure lined with a wear-resistant coating and extends through the module baffle 13 on one side of the module frame 11. A feed plunger pump 33 is installed on the frame 31. The outlet of the feed plunger pump 33 is connected to the diaphragm filter assembly 32, and the inlet of the feed plunger pump 33 is connected to the sludge tank. The frame 31, as the core load-bearing structure, organically integrates all components into the module support 12, ensuring a compact overall structure and balanced stress distribution, thus avoiding the poor coordination problem caused by the dispersed components of traditional equipment. The feeding plunger pump 33 is directly connected to the sludge tank and the diaphragm filter assembly 32, which can stably transport sludge to the filter chamber of the diaphragm filter assembly 32. In conjunction with the pressing pump group 34, the diaphragm filter assembly 32 is squeezed by the driving end. The "feeding-pressing" coordinated action ensures the sludge dewatering efficiency. The filtrate separated by the diaphragm filter assembly 32 is quickly discharged through the water outlet pipe and the drain pipe of the frame 31, realizing efficient solid-liquid separation. The transport mechanism 35 located below the diaphragm filter assembly 32 can directly receive the dewatered filter cake and transport it to the subsequent processing stage.
[0043] Furthermore, such as Figure 1As shown, the constant temperature and humidity system includes a temperature and humidity sensor 51, a heating element 52, and a dehumidification component 53. The temperature and humidity sensor 51 is mounted on the module support 12, while the heating element 52 and the dehumidification component 53 are mounted on the module frame 11. The temperature and humidity sensor 51 mounted on the module support 12 can monitor the real-time temperature and humidity data around the sludge filter press assembly at close range, ensuring that the sensed environmental parameters are highly consistent with the core area of the filter press, providing a basis for regulation. The heating element 52 and the dehumidification component 53 installed on the module frame 11 can act evenly on the entire module through the installation space formed by the module baffle 13. Based on the parameters fed back by the temperature and humidity sensor 51, the heating element 52 or the dehumidification component 53 is activated through the electrical control box 2. When the ambient humidity is high, the dehumidification component 53 quickly reduces the water vapor content in the air to prevent the sludge from becoming more sticky and adhering to the filter cloth due to moisture absorption. When the temperature is low, the heating element 52 maintains a suitable temperature to prevent the sludge from solidifying at low temperatures and affecting the filtration permeability. It effectively solves the problems of unstable dewatering efficiency and easy clogging of filter cloth caused by the fluctuation of ambient temperature and humidity in traditional diaphragm filter presses. It ensures that the diaphragm filter component 32 is always in the optimal working environment, which not only improves the consistency of sludge dewatering effect, but also reduces the frequency of equipment downtime for cleaning due to environmental factors. Combined with the integrated operation of the sludge filter press assembly, it further extends the service life of the filter cloth and filter press component, providing key environmental protection for the efficient and stable operation of the entire module.
[0044] Furthermore, such as Figure 1 As shown, the camera assembly includes at least two cameras 61; the shooting range of the two cameras 61 covers the installation position of the sludge dewatering assembly. In this embodiment, both cameras 61 are high-definition cameras, which can clearly capture key operational details such as the sealing status of the diaphragm filter assembly 32, the permeability of the filter cloth, and the squeezing accuracy of the pressing pump group 34. They can also promptly detect abnormal problems such as sludge leakage, loose or displaced components, avoiding the blind spots and lags of traditional manual inspections. The real-time images captured by the cameras 61 can be synchronously fed back to the remote operation interface of the electrical control box 2, allowing operators to remotely view the equipment's operating status. This comprehensive and visualized monitoring design, in conjunction with the environmental control of the constant temperature and humidity system and the entire process operation of the sludge dewatering assembly, helps operators quickly locate faults and control the operation process, reducing equipment downtime or substandard dewatering effects caused by untimely handling of abnormalities, further ensuring the reliability and stability of the entire sludge dewatering module.
[0045] The sludge dewatering module for wastewater treatment provided in this embodiment is used as follows: Before use, the height of the support rod 16 under the module bracket 12 is adjusted to adapt the equipment to the flatness of the installation site, completing quick leveling and fixing. Then, the feed inlet of the feed plunger pump 33 is connected to the sludge tank of the wastewater treatment plant, and the electrical control box 2 is connected to the power supply system to complete the linkage debugging of each component. After starting the equipment, the feed plunger pump 33 is started through the electrical control box 2 to stably transport the sludge into the filter chamber of the diaphragm filter assembly 32. At the same time, the temperature and humidity sensor 51 collects the temperature and humidity data inside the module in real time and synchronously feeds the data back to the remote operation interface of the electrical control box 2 for the operator to view and monitor in real time. The operator determines whether the environment needs to be adjusted according to the temperature and humidity parameters displayed on the interface. If the temperature is lower than the set threshold, the heating element 52 can be started through the electrical control box 2 through the remote operation interface to increase the temperature. If the humidity is higher than the set value, the dehumidification assembly 53 is started through the remote operation interface to reduce the water vapor content in the module and ensure that the sludge is always in a physical state conducive to filtration. Once the sludge is filled to the preset volume, the electrical control box 2 controls the drive end of the pressing pump group 34 to apply pressure to the diaphragm filter assembly 32, achieving deep pressing and dewatering of the sludge. The separated filtrate flows through the outlet pipe of the diaphragm filter assembly 32 into the drain pipe on the frame 31, and is directly discharged into the sewage treatment network. During this process, two high-definition cameras capture the sealing status of the diaphragm filter assembly 32, the permeability of the filter cloth, and the operation of the pressing pump group 34 throughout the process. The real-time images are simultaneously fed back to the remote operation interface, allowing operators to remotely monitor the equipment's operating status in real time. If any abnormalities such as sludge leakage or loose parts are detected, the operator can report them. After pressing is completed, the diaphragm filter assembly 32 opens to unload, and the dewatered filter cake falls directly to the conveying mechanism 35 below. The filter cake is then smoothly transported to the outside of the module through the filter cake transport channel of the conveying mechanism 35, ready to enter the next work cycle or to be shut down. This significantly reduces the intensity of manual operation and environmental interference, adapting to the continuous operation needs of sewage treatment plants of different sizes.
[0046] Example 2:
[0047] This embodiment provides a sludge dewatering module for wastewater treatment, which includes all the structures of the sludge dewatering module for wastewater treatment described in Embodiment 1.
[0048] like Figure 5As shown, in this embodiment, the sludge dewatering module also includes a fresh air system. The fresh air system is located at the top of the module frame 11, and its supply duct 42 and exhaust duct 43 connect to the interior of the module frame 11. The newly added fresh air system in this embodiment, through its installation layout at the top of the module frame 11 and the connection design between the supply duct 42, exhaust duct 43, and the inner cavity, complements the existing temperature and humidity control system. This allows for controlled airflow and replacement without compromising the airtightness of the inner cavity of the housing 1, promptly removing odorous gases, locally accumulated moisture, and heat generated during sludge dewatering, thus preventing problems such as filter cloth mold and component corrosion caused by air pollution. Furthermore, the fresh air supply provides a more balanced control basis for the temperature and humidity control system, reducing localized temperature and humidity imbalances. This further enhances the stability of the sludge dewatering environment. At the same time, the fresh air system can work with the data feedback from the temperature and humidity sensor 51 to achieve linkage and adaptation between the fresh air volume and temperature and humidity control. This not only ensures the suitable environment required for sludge filtration but also effectively improves the air quality inside the module, prevents secondary pollution caused by odor leakage, and extends the service life of electronic components such as monitoring components and electrical control box 2. It forms an organic whole with the original sealed structure and integrated functions, allowing the sludge dewatering module to operate efficiently and stably while also being environmentally friendly and durable, making it more suitable for long-term continuous wastewater treatment operations.
[0049] Furthermore, such as Figure 5 and Figure 6As shown, the fresh air system also includes a fresh air unit 41; the fresh air unit 41 is installed on the top of the module frame 11; the air outlet of the fresh air unit 41 is connected to the air supply pipe 42, and the air outlet of the fresh air unit 41 is connected to the exhaust pipe 43. As the core power source for fresh air circulation, the connection between the air outlet and the air supply pipe 42, and the air outlet and the exhaust pipe 43 of the fresh air unit 41, can provide stable and controllable air volume and air pressure, realizing active replacement and circulation of air inside the module frame 11. It can quickly introduce fresh air from the outside into the inner cavity through the air supply pipe 42, while efficiently expelling odor gases generated during sludge dewatering, locally accumulated high humidity air, and heat dissipation from equipment operation through the exhaust pipe 43, avoiding the problems of incomplete ventilation and air stagnation that exist in passive ventilation; it can also form a linkage with the temperature and humidity constant system and temperature and humidity sensor 51 through the air volume adjustment function of the fresh air unit 41, and adjust the air volume according to the temperature and humidity data and odor concentration in the inner cavity. The active ventilation rate is adjusted to ensure effective air exchange while avoiding drastic temperature and humidity fluctuations caused by a large influx of fresh air, thus ensuring that the suitable environment required for sludge dewatering remains unaffected. Simultaneously, the active fresh air circulation not only effectively improves the air quality inside the module, preventing mold growth on the filter cloth and corrosion and aging of electronic components (monitoring components, electrical control box 2) due to high humidity, thus extending the overall service life of the equipment, but also prevents secondary pollution caused by odor leakage through directional exhaust. Together with the original sealed structure, integrated functions, and temperature and humidity control system, it forms a more complete synergistic system, further enhancing the environmental friendliness, stability, and long-term operational reliability of the sludge dewatering module, adapting to the needs of high-load, continuous wastewater treatment operations.
[0050] In this embodiment, a rectangular mounting base (not shown) is provided at the top of the module frame 11 corresponding to the position of the fresh air system. The mounting base is made of 3mm thick galvanized steel plate welded to the top crossbeam of the module frame 11. The four edges of the mounting base protrude upward to form a 10mm high limiting stop, which is used to laterally position the fresh air unit 41. Four waist-shaped mounting holes (15mm long axis and 10mm short axis) are pre-drilled on the mounting base, and the hole positions correspond one-to-one with the mounting feet at the bottom of the fresh air unit 41. The fresh air unit 41 is fixed to the mounting base by four sets of stainless steel bolts. After the bolts pass through the mounting feet of the fresh air unit 41 and the oblong holes of the mounting base, they are locked with anti-loosening nuts. The oblong hole design allows the fresh air unit 41 to be finely adjusted in horizontal position within ±5mm, which facilitates the connection of the air supply pipe 42, the exhaust pipe 3 and the reserved interface of the module baffle 13 on the top of the module frame 44. A 5mm thick nitrile rubber shock-absorbing pad is also placed between the fresh air unit 41 and the mounting base. The shock-absorbing pad has corresponding through holes that match the bolts, which can effectively reduce the vibration of the fresh air unit 41 during operation to the module frame 11 and reduce noise.
[0051] Furthermore, such as Figure 6As shown, in this embodiment, the fresh air unit 41 is equipped with a supply fan 44 and an exhaust fan 45; the airflow ratio of the supply fan 44 to the exhaust fan 45 is 4:5. This creates a slight negative pressure environment within the module frame 11, preventing leakage of sludge and odors from the internal air due to positive pressure. Furthermore, the exhaust fan 45, with its slightly greater pulling force than the supply fan 44, drives rapid airflow and thorough replacement, ensuring efficient removal of high-humidity gases, odors, and heat generated during sludge dehydration, while preventing the disorderly infiltration of untreated external air. This airflow ratio prevents drastic fluctuations in internal temperature and humidity due to excessive exhaust volume, and also avoids incomplete air replacement due to insufficient supply volume. It achieves precise coordination with the temperature and humidity control system, ensuring air quality. While allowing airflow, sufficient buffer space is reserved for temperature and humidity control to maintain the stable environment required for sludge dewatering. In addition, slight negative pressure can also help improve the permeability of the filter cloth of the diaphragm filter component 32, reduce the risk of filter cloth blockage caused by local moisture accumulation, and reduce the probability of corrosion and aging of electronic components such as monitoring components and electrical control box 2 due to high humidity air. It works organically with the active circulation function of the fresh air host 41 and the sealed structure of the module to further enhance the environmental protection, operational stability and long-term durability of the sludge dewatering module, making it more suitable for high-load and continuous sewage treatment operation scenarios.
[0052] In this embodiment, the dehumidification component 53 includes a dehumidification box and a humidity sensor switch. The dehumidification box is installed inside the module frame 11, or it can be detachably installed inside the exhaust pipe 43 of the fresh air system by means of a snap-fit. The humidity sensor switch is linked with the exhaust fan 45. When the humidity in the chamber is greater than 85%, the humidity sensor switch triggers the exhaust fan 45 to increase its speed, thereby accelerating the discharge of humid air through the dehumidification box.
[0053] Example 3:
[0054] This embodiment provides a sludge dewatering module for wastewater treatment, which includes all the structures of the sludge dewatering module for wastewater treatment described in Embodiment 1.
[0055] like Figure 7 and Figure 8 As shown, in this embodiment, the housing 1 is provided with a gas-liquid co-purification channel, which includes a filtrate guide channel 111 and a gas baffle chamber 112. The filtrate guide channel 111 is set on the base 14 of the module bracket 12. One end of the filtrate guide channel 111 is connected to the filtrate outlet of the membrane filter assembly 32, and the other end of the filtrate guide channel 111 is connected to an external filtrate treatment unit. The bottom of the channel is inclined towards the filtrate outlet end with a slope of 3°~5°. The gas baffle chamber 112 is located above the filtrate guide channel 111 and is connected to the exhaust pipe 43 of the fresh air system. The gas baffle chamber 112 is provided with 3~5 sets of baffles (not shown). The outlet end of the gas baffle chamber 112 is provided with an activated carbon filter layer with a thickness of 50~80mm.
[0056] Specifically, the filtrate guide channel's 3°~5° incline ensures that the filtrate discharged from the diaphragm filter assembly flows rapidly to the outlet, preventing secondary pollution caused by stagnation within the housing and improving filtrate discharge efficiency. The gas baffle chamber guides the odorous gas discharged from the fresh air system to fully contact the filtrate in the guide channel through 3~5 sets of baffles. The residual flocculants and alkaline substances in the filtrate preliminarily neutralize acidic odorous components such as hydrogen sulfide and ammonia. Combined with the 50~80mm thick activated carbon filter layer at the outlet, deep purification is achieved, significantly improving deodorization efficiency without the need for additional deodorizing agents, making it more economical and environmentally friendly. At the same time, this channel integrates filtrate guidance and gas purification functions within the housing, reducing external pipe connections and equipment space occupation, further enhancing the integrated and compact design advantages of the sludge dewatering module, and improving the space utilization and operational stability of the wastewater treatment site.
