Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a continuous wastewater treatment device. Background Technology

[0002] In the process of modern industry and urbanization, wastewater treatment has become a major challenge for cities and industrial enterprises. Wastewater contains a large number of harmful substances and pollutants, and direct discharge without treatment will cause serious harm to the environment and public health. Therefore, efficient and reliable wastewater treatment equipment has extremely important application value in the field of environmental protection, especially in industries such as aquaculture, chemical industry, pharmaceutical industry and food processing, where the demand for wastewater treatment is more urgent. In order to meet increasingly stringent environmental standards and regulations, continuous innovation and optimization of wastewater treatment technology is particularly crucial.

[0003] Currently, traditional wastewater treatment plants typically employ fixed filtration systems, where filter elements are fixed inside the treatment unit to remove pollutants by filtering wastewater. However, fixed filtration systems have a significant drawback: as usage time increases, the surface of the filter elements gradually becomes clogged with pollutants, leading to a significant decrease in filtration efficiency. To maintain filtration performance, periodic shutdowns are required for cleaning and filter element replacement. Current wastewater treatment plants may extend the lifespan of filter elements by increasing the number or area of ​​filter elements, but periodic shutdowns for maintenance are still necessary. Furthermore, fixed filter elements cannot dynamically adjust for pollutant accumulation during wastewater treatment, resulting in a gradual decrease in filtration efficiency. This fails to meet the demands for efficient and continuous treatment, increasing maintenance costs and time, and impacting the continuity and efficiency of wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to provide a continuous wastewater treatment device that saves a significant amount of time and cost in maintaining filter components, and effectively improves the continuity and efficiency of wastewater treatment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a continuous wastewater treatment device, including a support component and a filter component;

[0007] The supporting component has a sewage treatment chamber;

[0008] The filtration assembly includes a drain element and a filter element, wherein the drain element is at least partially located within the wastewater treatment chamber, and the filter element is rotatably connected to the outer surface of the drain element located within the wastewater treatment chamber.

[0009] It also includes a cleaning component, the output end of which faces the outer surface of the filter element.

[0010] Optionally, the filter element includes a filter frame and a filter screen. The filter frame is sleeved on the outer surface of the drain component located inside the sewage treatment chamber, and a filtration space is formed between the edge of the filter frame and the outer surface of the drain component. The filter screen is disposed on the filter frame to close the filtration space.

[0011] Optionally, the drainage component includes a drainage box and a drainage pipe. The filter element is rotatably connected to the outer surface of the drainage pipe. One end of the drainage pipe penetrates the inner wall of the sewage treatment chamber to discharge the filtered water. The drainage box is fixedly connected to the end of the drainage pipe located inside the filter element, and the drainage pipe communicates with the drainage box.

[0012] Optionally, the filter frame has a polygonal or circular cross-section.

[0013] Optionally, the cleaning assembly includes a cleaning pipe and a nozzle. The cleaning pipe is at least partially located inside the wastewater treatment chamber, and the cleaning pipe located inside the wastewater treatment chamber at least partially overlaps with the projection of the filter element. The nozzle is correspondingly opened on the surface of the cleaning pipe that overlaps with the projection of the filter element, and the output end of the nozzle faces the outer surface of the filter element and is inclined relative to the outer surface of the filter element.

[0014] Optionally, the supporting component includes a supporting shell, the sewage treatment chamber is opened inside the supporting shell, a sewage inlet pipe is fixedly connected to the side of the supporting shell, the output end of the sewage inlet pipe is located inside the sewage treatment chamber, and the sewage inlet pipe is located above or below the filter element, and a drain pipe is opened on the side of the supporting shell.

[0015] Optionally, it may also include a drive component for driving the filter element to rotate.

[0016] This utility model provides a continuous wastewater treatment device, which has the following beneficial effects:

[0017] This continuous wastewater treatment device collects wastewater through a wastewater treatment chamber. Wastewater enters the chamber above the filter element and is filtered. The filtered water is then discharged through a drain. After a period of time, the filter element accumulates pollutants, affecting its filtration efficiency. To address this, a cleaning component is installed to clean the filter element. Water sprayed from the cleaning component's output flushes and cleans the filter element. Because the cleaning component's output faces the outer surface of the filter element, the flushing water generates a certain thrust to rotate the filter element, or it can be manually rotated. As the filter element rotates on the drain, the filtered portion comes into contact with the water surface after being flushed and rotated by the cleaning component. Water surface vibration causes pollutants to fall into the wastewater cleaning chamber. Simultaneously, the unfiltered parts of the filter element are replaced by the continuously filtering parts, allowing each part of the filter element to take turns performing the filtration task. This greatly extends the service life of the filter element. The replaced parts of the filter element are cleaned to ensure that the filter element is always in optimal working condition. During operation, the filtration area for filtering wastewater is rotated periodically to achieve a three-stage cycle operation of "filtration-cleaning-rotation". This facilitates cleaning while allowing for continuous filtration without the need to stop the machine to replace the filter element, saving a lot of maintenance time and costs. Cleaning prevents the filtration effect from decreasing due to the accumulation of pollutants, greatly improving the efficiency of wastewater treatment and forming a highly efficient and continuous circulating filtration system.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 3 The present invention provides a technical solution: a continuous sewage treatment device, comprising a support component 1 and a filter component 2;

[0024] The supporting component 1 has a sewage treatment chamber 11;

[0025] The filter assembly 2 includes a drain element 21 and a filter element 22. The drain element 21 is at least partially located inside the wastewater treatment chamber 11, and the filter element 22 is rotatably connected to the outer surface of the drain element 21 located inside the wastewater treatment chamber 11.

[0026] It also includes a cleaning component 3, the output end of which faces the outer surface of the filter element 22;

[0027] The continuous wastewater treatment device consists of two parts: a support component 1 and a filter component 2. The support component 1 has a wastewater treatment chamber 11 for collecting and storing wastewater. The filter component 2 includes a drain component 21 and a filter component 22. The drain component 21 is at least partially located inside the wastewater treatment chamber 11 and serves to discharge the filtered wastewater. The filter component 22 is rotatably connected to the outer surface of the drain component 21 located inside the wastewater treatment chamber 11. The filter component 22 can rotate so that different parts of it take turns contacting the wastewater for filtration. The purpose of this is that the filter component 22 can be continuously replaced with new filter surfaces after a period of use, avoiding the frequent shutdown and cleaning problems caused by filter component 22 clogging in traditional fixed filtration systems. This not only ensures that the filter component 22 is always in the best working condition and improves filtration efficiency, but also significantly extends the service life of the filter component 22 and reduces maintenance costs and time.

[0028] In this embodiment, the filter element 22 can also be configured as a modular structure, allowing for quick replacement of the module instead of the entire filter element 22 when it becomes clogged. This enables rapid disassembly and assembly through standardized interfaces, improving maintenance efficiency. Furthermore, a self-cleaning auxiliary function can be added to the surface of the filter element 22. By setting a vibration device on the surface of the filter element 22 or using ultrasonic technology, contaminants attached to the surface of the filter element 22 can be automatically removed, thereby further reducing the frequency and difficulty of manual cleaning.

[0029] In this embodiment, as a preferred solution, the filter element 22 includes a filter frame 221 and a filter screen 222. The filter frame 221 is sleeved on the outer surface of the drain element 21 located inside the sewage treatment chamber 11, and a filtration space is formed between the edge of the filter frame 221 and the outer surface of the drain element 21. The filter screen 222 is disposed on the filter frame 221 to seal the filtration space. The filter frame 221, by being sleeved on the outer surface of the drain element 21 located inside the sewage treatment chamber 11, forms a stable support structure and can rotate relative to it. A sealing element is provided at the connection between the filter frame 221 and the drain element 21. The sealing element is a common knowledge technology known to those skilled in the art and will not be described in detail here. Its purpose is to ensure that sewage enters the drain element 21 after passing through the filter frame 221. A filtration space is formed between the edge of the filter frame 221 and the outer surface of the drain component 21. When sewage flows through the filter component 22, it needs to enter the filtration space first. The filter screen 222 is set on the filter frame 221 to close the filtration space, so that sewage must pass through the filter screen 222 to enter the filtration space, and then enter the drain component 21. The filter frame 221 provides a solid support, while the filter screen 222 performs the actual filtration operation. The pollutants in the sewage are effectively trapped outside the filter screen 222, ensuring that the discharged sewage meets the treatment requirements. Due to the combined structure of the filter frame 221 and the filter screen 222, the filter screen 222 can be replaced or cleaned more easily, which extends the service life of the filter component 22 and maintains a high efficiency in sewage treatment.

[0030] Multiple layers of filter screens 222 can also be installed in the filtration space to form a multi-stage filtration system, thereby further improving the filtration effect and wastewater treatment efficiency.

[0031] In this embodiment, as a preferred solution, the drainage component 21 includes a drainage box 211 and a drainage pipe 212. A filter element 22 is rotatably connected to the outer surface of the drainage pipe 212. One end of the drainage pipe 212 penetrates the inner wall of the sewage treatment chamber 11 to discharge filtered water. The drainage box 211 is fixedly connected to the end of the drainage pipe 212 located inside the filter element 22, and the drainage pipe 212 communicates with the drainage box 211. That is, clean water entering the drainage box 211 can enter the drainage pipe 212 and be discharged. The rotatable connection between the filter element 22 and the drainage pipe 212 enables the filter element 22 to rotate flexibly. One end of the drainage pipe 212 penetrates the inner wall of the sewage treatment chamber 11, effectively discharging filtered water from the sewage treatment chamber 11, ensuring smooth sewage flow and timely discharge of treated water. The drainage box 211 is fixedly connected to the end of the drainage pipe 212 located inside the filter element 212. Water entering the filtration space first falls into the drain box 211 and then flows into the drain pipe 212 for discharge. The drain box 211 helps collect the filtered water, ensuring a stable connection between the drain pipe 212 and the filter element 22. After entering the drain box 211, the filtered water flows evenly into the drain pipe 212. One end of the filter element 22 is rotatably connected to the outer surface of the drain pipe 212, allowing it to rotate. The other end of the filter element 22 is rotatably connected to the drain box 211, making the rotation of the filter element 22 more stable. This ensures that each part of the filter element 22 can take turns contacting the sewage for filtration, improving the uniformity and continuity of sewage treatment. At the same time, it effectively prevents sewage blockage or poor flow during the filtration process, ensuring the efficient operation of the entire sewage treatment system.

[0032] In this embodiment, as a preferred option, the cross-section of the filter frame 221 is polygonal or circular.

[0033] Specifically, the polygon can be hexagonal. Compared with a circle, the hexagonal shape can more efficiently receive the thrust of the cleaning component 3 during rinsing, allowing the filter frame 221 to rotate. The hexagonal cross-section provides a stable polygonal support structure, which can evenly distribute the water flow pressure during filtration, reduce stress concentration in one direction, and thus improve the overall strength and durability of the filter frame 221. The circular cross-section provides a continuous curved surface, reducing the resistance of the water flow inside the filter frame 221, allowing sewage to flow more smoothly through the filter element 22, effectively enhancing the structural stability and filtration efficiency of the filter frame 221. It also facilitates the tight fit between the filter frame 221 and the drainage element 21, ensuring the continuity and uniformity of the filtration process. Both hexagonal and circular cross-sections of the filter frame 221 are easy to manufacture and maintain, simplifying the production process and subsequent cleaning work.

[0034] In this embodiment, the cross-section of the filter frame 221 can also be designed as an ellipse or an octagon. The elliptical cross-section can maintain the advantages of fluid dynamics while providing higher structural strength in certain directions, which helps to meet the filtration requirements under high pressure differential environment. The octagonal cross-section combines the stability of the polygonal structure with the uniform support provided by the larger number of sides, which can further improve the durability and filtration uniformity of the filter frame 221.

[0035] In this embodiment, as a preferred option, the cleaning assembly 3 includes a cleaning pipe 31 and a nozzle. The cleaning pipe 31 is at least partially located within the wastewater treatment chamber 11, and the cleaning pipe 31 located within the wastewater treatment chamber 11 at least partially overlaps with the projection of the filter element 22. The nozzle is correspondingly located on the surface of the cleaning pipe 31 where the projection of the filter element 22 overlaps, and the output end of the nozzle faces the outer surface of the filter element 22 and is relatively inclined to the outer surface of the filter element 22. The fact that the cleaning pipe 31 at least partially overlaps with the projection of the filter element 22 ensures that the cleaning water flow can directly act on the surface of the filter element 22. The nozzle is correspondingly located on the surface of the cleaning pipe 31 where the projection of the filter element 22 overlaps with the projection of the filter element 22. On the overlapping surface, the output end of the nozzle faces the outer surface of the filter element 22 and is set at a relative angle to the outer surface of the filter element 22. This inclined design allows the cleaning water to be sprayed onto the surface of the filter element 22 at an inclined angle, thereby enhancing the cleaning effect and ensuring that the dirt on the surface of the filter element 22 can be efficiently washed away. At the same time, the impact force generated by the water pushes the filter element 22 to rotate. The cleaning component 3 can clean the dirt on the surface of the filter element 22 periodically or in real time without affecting the normal operation of the filter element 22, maintaining the high-efficiency filtration capacity of the filter element 22, reducing the frequency of manual cleaning, and improving the continuity and efficiency of sewage treatment.

[0036] Alternatively, a rotating nozzle design can be adopted, which allows the nozzle to rotate and spray cleaning water during the cleaning process, thereby covering the entire surface of the filter element 22. This design can further enhance the cleaning effect and ensure that all parts of the filter element 22 can be cleaned evenly.

[0037] In this embodiment, as a preferred option, the supporting component 1 includes a supporting shell 12, a sewage treatment chamber 11 is opened in the supporting shell 12, a sewage inlet pipe 13 is fixedly connected to the side of the supporting shell 12, the output end of the sewage inlet pipe 13 is located in the sewage treatment chamber 11, and the sewage inlet pipe 13 is located above or below the filter element 22. A drain pipe 14 is opened on the side of the supporting shell 12. Through the function of the drain pipe 14, after filtering for a period of time, the drain pipe 14 can be opened to discharge sewage.

[0038] In this embodiment, the method of use can be adjusted by setting the sewage inlet position. When it is set in the sewage treatment chamber 11 above the filter element 22, the sewage flows out from above the filter element 22, then falls into the drain box 211 after passing through the filter screen 222, and then enters the drain pipe 212. After filtering for a period of time, the cleaning component 3 is opened for rinsing, and the filter element 22 is rotated for cleaning. The rotation causes the attached pollutants to fall off.

[0039] When installed at the bottom of the sewage treatment chamber 11, the sewage level rises slowly, and the sewage is collected through the sewage treatment chamber 11. The filter element 22 located in the sewage treatment chamber 11 filters the sewage above the water level. The filtered sewage enters the drain 21 and is discharged. At this time, at least part of the filter element 22 is not in contact with the sewage. After the filter element 22 has been used for a period of time, the part of the filter element 22 that is constantly in contact with the sewage will become clogged with pollutants, affecting the filtration effect. By rotating the filter element 22, which is rotatably connected to the outer surface of the drain 21, the filter element 22 can be rotated. As the filter element 22 rotates on the drain 21, the part of the filter element 22 that is not in contact with the sewage replaces the part that is constantly in contact with the sewage, thus improving the filtration effect of the filter element 22. Each part of filter element 22 can take turns performing filtration tasks, thus greatly extending the service life of filter element 22. Subsequently, the replaced parts of filter element 22 are cleaned (i.e., the outer surface of filter element 22 is cleaned by cleaning component 3), ensuring that filter element 22 is always in optimal working condition. During operation, the filtration areas that come into contact with sewage are rotated periodically to achieve a three-stage cycle operation of "non-contact-filtration-cleaning". This facilitates cleaning while allowing for continuous filtration without the need to stop the machine to replace filter element 22, saving a lot of maintenance time and costs. Cleaning also prevents the filtration effect from decreasing due to the accumulation of pollutants, greatly improving the efficiency of sewage treatment and forming a highly efficient and continuous circulating filtration system.

[0040] In this embodiment, as a preferred option, a drive component is also included. The drive component is used to drive the filter element 22 to rotate. The drive component is connected by a mechanical connection or an electric device. That is, the drive component is set on the outer side of the bearing shell 12, and the output end extends into the sewage treatment chamber 11 and is connected to the filter element 22. The drive component can be a drive motor. The drive motor can be directly fixedly connected to one end of the filter element 22, or a transmission gear can be set on one end of the filter element 22, and a corresponding drive gear can be set on the output end of the drive motor. The drive gear and the transmission gear mesh with each other. The drive motor drives the filter element 22 to rotate on the outer surface of the drain component 21. Different parts of the filter element 22 can take turns contacting the sewage for filtration, thereby avoiding the problems of clogging and pollutant accumulation caused by long-term use of a single area. The drive component ensures the automatic rotation of the filter element 22, avoiding insufficient thrust of the cleaning component 3 during flushing, which would prevent the filter element 22 from rotating. This achieves self-cleaning, circulation and continuous filtration, improves the operating efficiency of filtration, ensures the continuity and stability of sewage treatment, and achieves a highly efficient sewage filtration effect.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
