It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a drinking water filtering device, including a cylinder body 1, a cylinder cover 2 is fixedly installed at the top end of the cylinder body 1, mounting ears 15 are fixedly installed on the surfaces of both the cylinder body 1 and the cylinder cover 2, and the mounting ears 15 are arranged in a circular pattern on the surfaces of the cylinder body 1 and the cylinder cover 2, and can be fixed by bolts or welding. This fixing method ensures the stability and reliability of the structure. A motor 3 is fixedly installed at the top end of the cylinder cover 2, and a spiral blade 4 is installed at the output end of the motor 3. This connection can be achieved by key connection or fastening screws to ensure that the spiral blade 4 is firmly connected to the output shaft of the motor 3 and prevent it from falling off during high-speed rotation. A water inlet pipe 5 is communicated with the top end of the cylinder cover 2, and a water outlet pipe 6 is communicated with the bottom end of the cylinder body 1. These pipe connections can be achieved by flange connection or threaded connection, which is easy to install and maintain. A frame 7 is fixedly installed on the surface of the cylinder body 1, and an explosion-proof glass 8 is fixedly installed inside the frame 7. The explosion-proof glass 8 is fixed by gluing or mechanical clamping to ensure its stability and explosion-proof performance under pressure changes.

[0025] Please refer to Figures 1-4, vertical grooves 9 are provided on the surface of the frame 7, and a sliding rod 10 is slidably connected to the inner wall of the vertical groove 9. This sliding connection allows the sliding rod 10 to move freely within the vertical groove 9. Usually, bearings or lubricating materials are used to reduce friction and ensure smooth sliding. One end of the sliding rod 10 is fixedly installed with a cross plate 11, a side block 13 is fixedly installed on the side surface of the cross plate 11, and a friction column 14 is fixedly installed inside the side block 13. The side block 13 is of an "L" - shaped structure, and the friction column 14 is in contact with the frame 7. The material of the friction column 14 is natural rubber. This design can effectively limit the movement of the sliding rod 10 and the cross plate 11 through friction and improve the stability during operation. A scraper 12 is fixedly installed on the back surface of the cross plate 11, and the scraper 12 is in contact with the surface of the explosion - proof glass 8. The material of the scraper 12 is PP plastic, which provides good chemical resistance and sufficient hardness to remove stains without damaging the glass surface. A filter element 21 is fixedly installed on the inner wall of the cylinder body 1. The drinking water entering through the water inlet pipe 5 is first driven by the spiral blade 4 driven by the motor 3. This rotation squeezes the drinking water through the filter element 21, filtering out the impurities in the water, and then the purified drinking water is discharged through the water outlet pipe 6.

[0026] Embodiment Two

[0027] Please refer to Figure 4 , a backwashing mechanism is provided on the inner wall of the cylinder body 1. The backwashing mechanism includes a water delivery pipe 16, and the water delivery pipe 16 is fixedly installed on the inner wall of the cylinder body 1, using bolt fixation or welding methods to ensure a stable structure and good waterproof performance. A disc 17 is fixedly installed at the bottom end of the water delivery pipe 16, and a nozzle 18 is fixedly installed on the top surface of the disc 17. The nozzles 18 are arranged in a circular pattern on the top surface of the disc 17. This arrangement can effectively distribute the water flow and achieve the effect of uniform backwashing. The top end of the water delivery pipe 16 is communicated with the water inlet pipe 5, realizing efficient water flow guidance. A valve A19 is installed on the surface of the water delivery pipe 16, and a valve B20 is installed on the surface of the water inlet pipe 5. The material of the valve is usually stainless steel or copper, and these materials have strong corrosion resistance and long service life.

[0028] Working principle: Drinking water enters through the water inlet pipe 5, and then the spiral blade 4 is driven to rotate by the motor 3. When the spiral blade 4 rotates, it can squeeze the drinking water. At this time, the drinking water can pass through the filter element 21, and the drinking water can be filtered at this time. Then, the purified drinking water is discharged from the water outlet pipe 6. The explosion-proof glass 8 provided can facilitate the staff to check the working conditions inside the cylinder body 1, timely judge the working state, and facilitate the maintenance operation. When there are stains on the surface of the explosion-proof glass 8, the staff only need to pull down the cross plate 11. The cross plate 11 then drives the sliding rod 10 to slide in the vertical groove 9. The cross plate 11 can then drive the scraping plate 12 to scrape the explosion-proof glass 8. At this time, the surface of the explosion-proof glass 8 can be cleaned by scraping. The friction column 14 provided and the frame 7 can generate friction force, and this friction force can limit the position of the scraping plate 12. When the scraping plate 12 is not in use, it can prevent the scraping plate 12 from moving randomly. The setting of the explosion-proof glass 8 in the present utility model enables the operator to directly observe the working state inside the cylinder body 1, which helps to promptly discover any abnormal conditions, such as filter clogging or wear of the filter material, so that adjustments or maintenance can be quickly carried out to ensure the stability and efficiency of the equipment operation. And if there are stains on the surface of the explosion-proof glass 8, through the simple action of pulling down the cross plate 11, the cross plate 11 will drive the sliding rod 10 to slide in the vertical groove 9, and the stains on the glass surface can be cleaned by the scraping plate 12. This structural design eliminates the need for disassembly or the use of complex tools for cleaning, making the daily maintenance simpler and faster. When it is necessary to rinse the filter element 21, the staff only need to open the valve A 19 and close the valve B 20. At this time, the drinking water entering through the water inlet pipe 5 can enter the disc 17 through the water delivery pipe 16, and then be sprayed out through the nozzle 18. At this time, the sprayed water can backwash the filter element 21 from bottom to top, so as to simply clean the filter element 21, thereby increasing the service life. The present utility model can start the backwashing process of the filter element 21 by simply operating, that is, opening the valve A 19 and closing the valve B 20. This simplified operation reduces the need for complex equipment or additional tools, making the cleaning process more convenient and fast. The backwashing can effectively remove the accumulated impurities and dirt from the filter element 21, reduce the clogging and wear of the filter material, not only extend the service life of the filter element 21, but also reduce the frequency and related costs of replacing the filter element 21. At the same time, the regular backwashing maintains the clean state of the filter element 21 and ensures the filtration efficiency. The clean filter element 21 can process the influent more effectively to ensure that the quality of the effluent meets the standards.

[0029] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
