[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. Note: The described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0027] As attached Figure 1 To be continued Figure 5 As shown, the integrated water purification device provided in this embodiment of the present invention employs a process of grid flocculation + upward-flowing inclined tube 5 sedimentation + filter 11 during water purification. The grid flocculation process involves adding flocculants to aggregate suspended solids in the water into larger particles, which are then removed by the combination of upward-flowing inclined tube 5 sedimentation and filter 11. The grid design increases the collision probability of particles, creating favorable flocculation conditions, promoting floc formation, and improving flocculation performance and settling speed. Secondly, the upward-flowing inclined tube 5 sedimentation utilizes laminar flow principles, controlling the direction and speed of water flow through the inclination angle and flow velocity of the inclined tube 5. This effectively separates mud and water, which slides to the bottom of the inclined tube 5 under gravity and is then discharged through the sludge removal system 7. This not only shortens particle settling and sedimentation time but also increases the sedimentation area, thereby improving treatment efficiency. Furthermore, the upward-flowing inclined tube 5 is rationally designed, operates stably, and can adapt to different water qualities and small-volume treatment needs. The collected clean water can be fed into the main channel 8 via the collection tank 4. By opening the inlet valve 9, the water can be filtered and fed into the filter using the V-shaped trough plate 16. After being filtered by the filter media, the water flows to the lower side of the filter plate 12, and finally, the purified water is output through the outlet. The purified water is then transferred from the filter tank 11 for use. When the water purification device is used for a long time, the backwashing system sequentially flushes the air and water in the filter tank 11 to remove surface impurities. To achieve the above effects, multiple collection tanks 4 can be installed on the upper side of the sedimentation tank 3 to facilitate the transfer of the upper layer of clean water in the sedimentation tank 3. After the water from the grid flocculation device 2 is fed into the sedimentation tank 3, an inclined pipe 5 is installed on the side of the sedimentation tank 3 near the grid flocculation device 2 to assist sedimentation. Large flocculated impurities fall to the lower side of the sedimentation tank 3, and the settled clean water flows to the collection tank 4 for transfer. Then, the same main channel 8 is installed between the multiple collection tanks 4 and the filter tank 11 as a sedimentation chamber for the clean water. The purified water can be directed to the filter tank 11 via the inlet valve 9, and then through the water distribution and drainage plates 15 set on both sides of the filter plate 12. A V-shaped groove plate 16 is set on the upper side of the two water distribution and drainage plates 15. The V-shaped groove plate 16 can be used for priority filtration, and then the filter media between the water distribution and drainage plates 15 and the filter plate 12 are used for filtration to complete the purification of the water source. Furthermore, the backwashing system in the water purification device is connected to the space constructed by the two water distribution and drainage plates 15, the filter plate 12 and the filter box, which facilitates the backwashing and purification processing of the purification device.

[0028] It is worth noting that, in order to facilitate the backwashing of the water purification device and the use of purified water, such as Figure 2As shown, an inlet pipe 1 is installed through one side of the grid flocculation device 2 as the input end of the water source. The backwashing system uses a backwashing air pipe 18 and a backwash inlet pipe 19 that are connected through the filter tank 11. The medium in the backwashing air pipe 18 and the backwash inlet pipe 19 can pass through the filter plate 12 and enter the two water distribution and drainage plates 15 to facilitate the backwashing of the device. The backwashing air pipe 18 is set on the upper side of the backwash inlet pipe 19, and the height of the backwashing air pipe 18 is set below the height of the filter plate 12. In some embodiments, the backwash inlet pipe 19 can use a U-shaped structure. A valve body is set in the middle of the backwash inlet pipe 19, and a connecting pipe is installed through the middle of the backwash inlet pipe 19. An air pump can be connected to the outside of the connecting pipe to facilitate the input of gas and the gas supply during the backwashing operation. Then, outlet pipes 20 can be installed through both sides of the backwash inlet pipe 19 as the outlet end of the filter tank 11 for efficient water distribution of the filter tank 11.

[0029] Furthermore, such as Figure 1 and 2 As shown, a vent pipe 17 can be installed through the outside of the filter tank 11 as the discharge end of the liquid in the filter tank 11. A through outlet hole can be provided in the space between the filter plate 12 and the water distribution and drainage plate 15 on the filter tank 11 to facilitate the discharge of purified water.

[0030] Furthermore, in some embodiments, to facilitate long-term use of the water purification device, such as... Figure 2 As shown, sludge discharge zones 6 are provided on the lower side of the inside of both the grid flocculation device 2 and the sedimentation tank 3. The lower end of the sludge discharge zone 6 is in the shape of a V-shaped trough. A sludge discharge system 7 is provided through the outside of both the grid flocculation device 2 and the sedimentation tank 3. By opening the sludge discharge system 7, the sediment can be transferred and discharged.

[0031] It is worth noting that, in order to facilitate backwashing of the water purification device and structural optimization of the water purification structure, such as... Figure 2 As shown, an inlet valve 9 is installed between the main channel 8 and the filter 11, and a drain valve 10 is installed between the sedimentation tank 3 and the filter 11. A water distribution and drainage space can be constructed between the water distribution and drainage plate 15 and the filter 11 through a partition. The drain valve 10 is located on the upper side of the partition, and a drainage channel 21 is installed on the sedimentation tank 3 below the drain valve 10 as the discharge end of the backwash water. When the water from 9 is discharged into the filter 11 for surface cleaning and when the water is introduced into the backwash inlet pipe 19 for backwashing, the excess water discharged from the backwash can be discharged through the drain valve 10 and the drainage channel 21, realizing the different sides of backwashing and water distribution, reducing the volume of the device and simplifying the structure of the device.

[0032] And in some embodiments, such as Figure 4As shown, the side of the filter plate 12 away from the backwashing system is tilted downwards, and a support layer 13 is set on the filter plate 12. Multiple filter heads 14 are installed through the support layer 13. The filter heads 14 can pass through the upper and lower sides of the filter plate 12 to facilitate the flow of water. Then, filter media is filled between the V-shaped groove plate 16 and the water distribution and drainage plate 15 to improve the water purification quality of the water source.

[0033] The filter 11, a uniform-particle filter media with V-shaped groove plates 16 and a low-resistance water distribution system involving air-water combined flushing and surface cleaning, plays a primary role in SS (suspended solids) removal. Its water distribution and air distribution process includes V-shaped groove plates 16, filter heads 14, filter plates 12, water distribution and drainage plates 15, a support layer 13, and filter media. The filter 11 is designed with V-shaped groove plates 16 for uniform water distribution and convenient backwashing for surface cleaning. The filter heads 14 and filter plates 12 are designed according to the specifications of the filter 11. Select filter head model 14 with a suitable opening ratio for water distribution; backwash water and air distribution enter the filter tank 11 from the water and air distribution system at the bottom of the water distribution and drainage plate 15, and are combined with surface cleaning for backwashing; backwash water is discharged after exceeding the water distribution and drainage plate 15; the support plate is made of pebble material with a particle size of 2-4mm and a filling thickness of 100-150mm; the filter media is quartz sand filter media with a particle size of 0.9-1.2mm and a filling thickness of 1000-1500mm.

[0034] To enable the V-groove plate 16 to be used for drainage and surface cleaning water intake, such as Figure 2 and 5 As shown, the outlet of the inlet valve 9 is aligned with the V-shaped groove plate 16. The lower end of the V-shaped groove plate 16 is opened to form the filter outlet of the structure, which facilitates the water supply inside the filter tank 11.

[0035] Of course, the above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
