Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtration, and specifically, to a device for sewage purification and filtration that is convenient for cleaning. Background Art

[0002] Sewage treatment refers to the purification process in which sewage meets the water quality standards for discharging into specific water bodies or for reuse. This process involves removing solid, liquid, and dissolved pollutants in sewage, including suspended solids, oils and fats, heavy metals, bacteria, viruses, and other harmful substances. As a key process in this process, the performance and efficiency of sewage treatment devices directly affect the final water quality treatment effect. These devices can effectively remove harmful substances in sewage, so that the treated water quality meets specific discharge standards or reuse requirements.

[0003] After retrieval, a Chinese patent with the publication number of CN220824537U discloses a filtration device for sewage treatment, including a box body and an upper cover. An inlet end and an outlet end are provided in the box body. A water inlet pipe and a water outlet pipe are respectively installed in the inlet end and the outlet end. A plurality of frame plates are provided between the inlet end and the outlet end. Filter plates are respectively inserted into the plurality of frame plates. Pressing plates are respectively sleeved on the upper ends of the plurality of filter plates. Both ends of the plurality of pressing plates are respectively in contact with the upper ends of the two side walls of the plurality of frame plates. A fixing mechanism is provided on the upper cover. The utility model relates to the technical field of sewage treatment. The utility model adopts a multiple filtration method. A plurality of filter plates are provided in the box body. The filter plates are inserted into the frame plates from the upper ends of the frame plates in an inserted manner. Therefore, when performing subsequent maintenance, after opening the upper cover, the filter plates can be pulled out, which is convenient for cleaning and disassembly.

[0004] There are some drawbacks in the existing devices during use. For example: in the above solution, when cleaning the filter plates, the staff needs to manually open the upper cover of the sewage treatment filtration device and perform operations such as disassembly, cleaning, and installation of the filter plates. This not only takes time and effort, but also may cause equipment damage or personal injury due to improper operation. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a device for sewage purification and filtration that is convenient for cleaning, and solve the problem that the filter plates can be cleaned without opening the box body.

[0006] The utility model provides the following technical solution: A device for sewage purification and filtration that is convenient for cleaning, including four bases. A filtration chamber is fixedly connected to the top ends of the four bases. A water inlet pipe is fixedly connected to the top of the filtration chamber. A water inlet valve is arranged on the outer side of the water inlet pipe. The water inlet pipe is communicated with the filtration chamber. Two filter plates are arranged on the inner top wall of the filtration chamber. The two filter plates are symmetrically and obliquely arranged. The top ends of the two filter plates are fixedly connected to the inner top wall of the filtration chamber. The two ends of the two filter plates are respectively fixedly connected to the two inner side walls of the filtration chamber. A sewage discharge assembly is arranged at the bottom ends of the two filter plates. A driving assembly is arranged on one outer wall of the filtration chamber. A cleaning assembly is arranged on the driving assembly.

[0007] In the above solution, the filtration chamber is fixedly connected to the top ends of the four bases, providing stable support for the entire device. Since the two filter plates are symmetrically and obliquely arranged, when sewage flows through the filter plates, it can be more evenly distributed to each part of the filter plates, thereby improving the filtration efficiency. In addition, the inclined design also helps the impurities and dirt in the sewage to slide down to the sewage discharge assembly more quickly, further improving the filtration effect. The cleaning assembly can automatically clean the dirt and impurities on the filter plates through the drive of the driving assembly, keeping the filter plates clean and maintaining the filtration efficiency. The setting of the water inlet valve enables the staff to precisely control the sewage flow rate entering the filtration chamber. According to the processing capacity of the filtration chamber and the current processing requirements, the staff can adjust the water inlet valve to ensure that the filtration chamber operates in the best working state.

[0008] As a preference of the above technical solution, the driving assembly includes a driving motor fixedly connected to one outer wall of the filtration chamber. The output end of the driving motor is fixedly connected to a rotating screw. The rotating screw horizontally penetrates one outer wall of the filtration chamber and is rotatably connected to one outer wall of the filtration chamber. The end of the rotating screw away from the driving motor is rotatably connected to the other outer wall of the filtration chamber.

[0009] In the above solution, the driving motor drives the rotating screw to rotate, so that the rotating screw drives the cleaning assembly to clean the dirt and impurities accumulated on the upper surface of the filter plates.

[0010] As a preference of the above technical solution, the cleaning assembly includes a moving plate threadedly sleeved on the outer side of the rotating screw. A limiting assembly is arranged at the top end of the moving plate. The moving plate is connected to the filtration chamber through the limiting assembly. Scrapers are respectively fixedly connected to both sides of the moving plate close to the upper surfaces of the two filter plates.

[0011] In the above solution, through the threaded connection between the moving plate and the rotating screw, when the driving motor drives the rotating screw to rotate, the moving plate can move along the length direction of the screw, so that the scrapers respectively fixedly connected to both sides of the moving plate can closely move along the upper surface of the filter plates, effectively scraping off the dirt and impurities accumulated on the filter plates.

[0012] Preferably, as the above technical solution, the limiting component includes a limiting block fixedly connected to the top end of the moving plate. A limiting groove adapted to the size of the limiting block is horizontally opened on the inner top wall of the filter chamber. The moving plate is slidably connected to the filter chamber through the limiting block.

[0013] In the above solution, the cooperation of the limiting block and the limiting groove enables the moving plate to move within a specified range, and also ensures the stability of the moving plate during the movement, avoiding possible shaking or deviation of the moving plate during the movement.

[0014] Preferably, as the above technical solution, the sewage discharging component includes a sewage discharging chamber fixedly connected to the bottom ends of the two filter plates. A sewage discharging pipe is fixedly connected to the bottom end of the sewage discharging chamber. The sewage discharging pipe is communicated with the sewage discharging chamber. One end of the sewage discharging pipe away from the sewage discharging chamber penetrates through the bottom end of the filter chamber and is fixedly connected to the bottom end of the filter chamber. A sewage discharging valve is arranged on the outer side of the end of the sewage discharging pipe away from the filter chamber.

[0015] In the above solution, after the sewage discharging valve is opened, the dirt and impurities scraped off from the upper surface of the filter plate can smoothly pass through the sewage discharging chamber and the sewage discharging pipe and be discharged, preventing these dirt from accumulating on the filter plate for a long time and affecting the filtering effect and the service life of the filter plate.

[0016] Preferably, as the above technical solution, a water outlet pipe is fixedly connected to the outer wall of one side of the filter chamber. A water outlet valve is arranged on the outer side of the water outlet pipe. The water outlet pipe is communicated with the filter chamber.

[0017] In the above solution, the setting of the water outlet valve allows the staff to control the discharge of the filtered sewage at any time according to actual needs. When the sewage in the filter chamber reaches the treatment standard, the staff only needs to simply operate the water outlet valve to realize the rapid discharge of the filtered sewage.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] In the present utility model, the driving motor drives the rotating screw to rotate, and then drives the moving plate to move stably along the length direction of the screw. The cooperation of the limiting block and the limiting groove limits the moving range of the moving plate, ensuring its stability and accuracy during the movement. When the moving plate moves, the scraping knives fixedly connected to both sides of the moving plate can closely move along the upper surface of the filter plate, thereby effectively scraping off the dirt and impurities accumulated on the filter plate. This automatic cleaning method not only improves the cleaning efficiency but also greatly reduces the labor intensity of the staff. When the sewage discharging valve is opened, the dirt and impurities scraped off from the upper surface of the filter plate can smoothly pass through the sewage discharging chamber and the sewage discharging pipe and be discharged. This design ensures that the dirt can quickly and smoothly leave the sewage treatment device, avoiding the accumulation and blockage of dirt inside the device and ensuring the smooth progress of the entire sewage treatment process.

[0025] Embodiment 1

[0026] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, the utility model provides a technical solution: a device for sewage purification and filtration that is convenient for cleaning, including four bases 10. The top ends of the four bases 10 are fixedly connected to a filtration chamber 11. The top end of the filtration chamber 11 is fixedly connected to a water inlet pipe 12. An inlet valve 13 is arranged on the outer side of the water inlet pipe 12. The water inlet pipe 12 is communicated with the filtration chamber 11. Two filter plates 20 are arranged on the inner top wall of the filtration chamber 11. The two filter plates 20 are symmetrically and obliquely arranged. The top ends of the two filter plates 20 are fixedly connected to the inner top wall of the filtration chamber 11. The two ends of the two filter plates 20 are respectively fixedly connected to the two inner side walls of the filtration chamber 11. A sewage discharge assembly is arranged at the bottom ends of the two filter plates 20. A driving assembly is arranged on one outer wall of the filtration chamber 11. A cleaning assembly is arranged on the driving assembly. In the specific use process, the top ends of the four bases 10 are fixedly connected to the filtration chamber 11, providing stable support for the entire device. Since the two filter plates 20 are symmetrically and obliquely arranged, when sewage flows through the filter plates 20, it can be more evenly distributed to each part of the filter plates 20, thereby improving the filtration efficiency. In addition, the inclined design also helps the impurities and dirt in the sewage to slide down to the sewage discharge assembly faster, further improving the filtration effect. The cleaning assembly can automatically clean the dirt and impurities on the filter plates 20 under the drive of the driving assembly, keeping the filter plates 20 clean and maintaining the filtration efficiency. The setting of the inlet valve 13 enables the staff to precisely control the sewage flow rate entering the filtration chamber 11. According to the processing capacity of the filtration chamber 11 and the current processing requirements, the staff can adjust the inlet valve 13 to ensure that the filtration chamber 11 operates in the best working state.

[0027] As an implementation manner in this embodiment, as Figure 1 and Figure 3 shown, the driving assembly includes a driving motor 30 fixedly connected to one outer wall of the filtration chamber 11. The output end of the driving motor 30 is fixedly connected to a rotating screw 31. The rotating screw 31 horizontally penetrates one outer wall of the filtration chamber 11 and is rotatably connected to one outer wall of the filtration chamber 11. The end of the rotating screw 31 away from the driving motor 30 is rotatably connected to the other outer wall of the filtration chamber 11. In the specific use process, the driving motor 30 drives the rotating screw 31 to rotate, so that the rotating screw 31 drives the cleaning assembly to clean the dirt and impurities accumulated on the upper surface of the filter plates 20.

[0028] As an implementation manner in this embodiment, as Figure 2 and Figure 3As shown in the figure, the cleaning component includes a moving plate 40 threadedly sleeved on the outer side of the rotating screw 31. A limiting component is arranged at the top end of the moving plate 40. The moving plate 40 is connected to the filter bin 11 through the limiting component. Scrapers 41 are fixedly connected to both sides of the moving plate 40 close to the upper surfaces of the two filter plates 20. During the specific use process, through the threaded connection between the moving plate 40 and the rotating screw 31, when the driving motor 30 drives the rotating screw 31 to rotate, the moving plate 40 can move along the length direction of the screw, so that the scrapers 41 fixedly connected to both sides of the moving plate 40 can closely move along the upper surface of the filter plate 20, effectively scraping off the dirt and impurities accumulated on the filter plate 20.

[0029] As an implementation manner in this embodiment, as Figure 2 and Figure 3 shown in the figure, the limiting component includes a limiting block 50 fixedly connected to the top end of the moving plate 40. A limiting groove 51 adapted to the size of the limiting block 50 is horizontally opened on the inner top wall of the filter bin 11. The moving plate 40 is slidably connected to the filter bin 11 through the limiting block 50. During the specific use process, the cooperation between the limiting block 50 and the limiting groove 51 enables the moving plate 40 to move within a specified range, and also ensures the stability of the moving plate 40 during the moving process, avoiding possible shaking or deviation of the moving plate 40 during the moving process.

[0030] As an implementation manner in this embodiment, as Figure 2 and Figure 3 shown in the figure, the sewage discharge component includes a sewage discharge bin 60 fixedly connected to the bottom ends of the two filter plates 20. A sewage discharge pipe 61 is fixedly connected to the bottom end of the sewage discharge bin 60. The sewage discharge pipe 61 is communicated with the sewage discharge bin 60. One end of the sewage discharge pipe 61 away from the sewage discharge bin 60 penetrates through the bottom end of the filter bin 11 and is fixedly connected to the bottom end of the filter bin 11. A sewage discharge valve 62 is arranged on the outer side of the end of the sewage discharge pipe 61 away from the filter bin 11. During the specific use process, after the sewage discharge valve 62 is opened, the dirt and impurities scraped off from the upper surface of the filter plate 20 can be smoothly discharged through the sewage discharge bin 60 and the sewage discharge pipe 61, preventing these dirt from accumulating on the filter plate 20 for a long time and affecting the filtering effect and the service life of the filter plate 20.

[0031] As an implementation manner in this embodiment, as Figure 1 and Figure 2 shown in the figure, a water outlet pipe 14 is fixedly connected to the outer wall of one side of the filter bin 11. A water outlet valve 15 is arranged on the outer side of the water outlet pipe 14. The water outlet pipe 14 is communicated with the filter bin 11. During the specific use process, the setting of the water outlet valve 15 allows the staff to control the discharge of the filtered sewage at any time according to actual needs. When the sewage in the filter bin 11 reaches the treatment standard, the staff only needs to simply operate the water outlet valve 15 to achieve the rapid discharge of the filtered sewage.

[0032] Working principle: Open the water inlet valve 13 to allow sewage to flow into the interior of the filter chamber 11 through the water inlet pipe 12 for filtration. The two filter plates 20 are symmetrically and obliquely arranged. When the sewage flows through the filter plates 20, it can be more evenly distributed to each part of the filter plates 20, thereby improving the filtration efficiency. In addition, the inclined design also helps the impurities and dirt in the sewage to slide down to the sewage discharge assembly more quickly, further improving the filtration effect. Open the water outlet valve 15 to allow the filtered sewage to flow out through the water outlet pipe 14. When it is necessary to clean the filter plates 20, drive the rotating screw 31 to rotate through the drive motor 30, and then drive the moving plate 40 to move stably along the length direction of the screw. The cooperation of the limit block 50 and the limit groove 51 limits the moving range of the moving plate 40, ensuring its stability and accuracy during movement. When the moving plate 40 moves, the scraping blades 41 fixedly connected to both sides of the moving plate 40 can closely move along the upper surface of the filter plates 20, thereby effectively scraping off the dirt and impurities accumulated on the filter plates 20. This automated cleaning method not only improves the cleaning efficiency but also greatly reduces the labor intensity of the staff. When the dirt and impurities on the filter plates 20 fall off, simultaneously open the sewage discharge valve 62, and the dirt and impurities scraped off from the upper surface of the filter plates 20 can smoothly pass through the sewage discharge chamber 60 and the sewage discharge pipe 61 for discharge. This design ensures that the dirt can quickly and smoothly leave the sewage treatment device, avoiding the accumulation and blockage of dirt inside the device and ensuring the smooth progress of the entire sewage treatment process.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
