[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-2 The utility model provides a technical solution: a smart integrated water purification device, including: a grid flocculation tank 9, an inclined tube sedimentation tank 6, and a V-shaped filter tank 4, wherein the grid flocculation tank 9, the inclined tube sedimentation tank 6, and the V-shaped filter tank 4 constitute a three-stage treatment process, and the V-shaped filter tank 4 is connected to a clean water pipe 10, and the clean water pipe 10 is connected to a clean water main outlet pipe;

[0025] The raw water enters the grid flocculation tank 9 through the raw water inlet 8, enters the transition zone 91 from the grid flocculation tank 9, flows through the inclined tube sedimentation tank 6, and then enters the V-type filter tank 4. The filtered water is collected by the clean water outlet pipe 10 and introduced into the clean water total outlet 1 for discharge;

[0026] The grid flocculation tank 9 is a flocculation tank that applies the turbulence theory. The plane layout of the grid flocculation tank 9 has multiple vertical shafts. The grid flocculation tank 9 is divided into many squares of equal area. The grid flocculation tank 9 is provided with a transition zone 91. The grid flocculation tank 9 is provided with a raw water inlet 8. The inlet water flows from one grid to the next in sequence, and flows up and down in an interlaced manner until the outlet. In two-thirds of the grids of the whole tank, grids or bars are placed horizontally. When the water flows through the gaps of the grids or bars, the water flows shrink. After passing through the mesh holes, the water flows expand, forming good flocculation conditions. Due to the appropriate pool height, it can be built together with the inclined tube sedimentation tank 6. The grid flocculation tank 9 has the advantages of small head loss, short flocculation time and good effect.

[0027] The flocculation area is divided into multiple grids, each grid is close to a square, and the grids are connected by orifices. In one grid, when the water inlet is at the top (or bottom), the water outlet is at the bottom (or top), and they are staggered diagonally. Due to the orifice jet effect, the water flow generates swirls in each grid in sequence, and because the orifice area gradually increases from the inlet to the outlet of the flocculation area, the flow velocity gradient decreases from large to small, and the water flow generates more small vortices, which promotes the full contact of the fine alum flowers in the raw water, increases the floccules, and is beneficial to improving the flocculation effect.

[0028] The partitions between the grids of the grid flocculation area 9 are opened along the pool wall. The positions of the holes are arranged in a vertical and horizontal manner to avoid water short-circuiting and improve volume utilization. The holes are rectangular in cross section, and each grid has a perforated mud discharge pipe 7 passing through it for mud discharge and cleaning;

[0029] The inclined tube sedimentation tank 6 uses inclined honeycomb fillers to divide the original sedimentation area into a series of shallow sedimentation layers. The suspended matter, solid matter or flocs formed after adding coagulants in the raw water gather into a thin mud layer on the surface of the inclined tube and slide to the sludge concentration area by gravity. The mud discharge pipe adopts a perforated pipe structure and is arranged along the bottom of the mud area to facilitate the thorough discharge of the sludge. The supernatant gradually rises along the inclined tube to the water collection tank to complete the solid-liquid separation.

[0030] The transition zone 91 of the grid flocculation tank 9 is connected to the inclined tube sedimentation tank 6;

[0031] The inclined tube sedimentation tank 6 is made according to the precipitation principle of removing dispersed particles in the horizontal flow sedimentation tank. By adding inclined tubes in the tank, the hydraulic radius is reduced and the wetted perimeter of the water section of the tank is increased. Therefore, when the water flow is at the same horizontal flow rate, the Reynolds number can be greatly reduced, thereby reducing the storage flow and promoting sedimentation. In addition, the addition of inclined tubes can also shorten the particle sedimentation distance, reduce the sedimentation time, and improve the sedimentation efficiency;

[0032] The inclined tube sedimentation tank 6 uses hexagonal honeycomb inclined tubes, and the water inlet adopts perforated wall rectification and water distribution to make the water flow evenly distributed. The gap between the inclined tube and the tank wall is also provided with a flow baffle to prevent water short circuit;

[0033] A mud discharge pipe is provided at the bottom of the inclined tube sedimentation tank 6. When the integrated water purification equipment runs continuously for a certain period of time, the PLC automatically opens the mud discharge valve to discharge the mud;

[0034] The inclined tube sedimentation tank 6 is connected to the V-shaped filter tank 4, and the clean water after sedimentation in the inclined tube sedimentation tank 6 flows into the V-shaped filter tank 4;

[0035] V-type filter 4 has the following functions:

[0036] 1. Constant water level and constant speed filtration, because the outlet valve can continuously adjust the opening degree as the water level changes, thus ensuring that the water level in the filter tank does not change during the entire filtration cycle, avoiding negative pressure in the filter layer;

[0037] 2. It uses uniform quartz sand for filtration, with large sewage interception capacity, long filtration cycle and good water purification effect;

[0038] 3. V-shaped water inlet trough to ensure uniform water distribution;

[0039] 4. The supporting layer is thin;

[0040] 5. Backwashing is a combination of air and water washing and surface sweeping at the same time, which has a high washing efficiency and can save water;

[0041] 6. The filter layer will become slightly expanded during backwashing, which can effectively prevent sand leakage;

[0042] Advantages of V-type filter 4:

[0043] 1. The filtering effect of V-type filter 4 is better than that of ordinary rapid filter;

[0044] 2. V-type filter 4 is a constant water level and constant speed filter, with balanced working state, stable operation, and a longer operating cycle than ordinary rapid filter;

[0045] 3. The backwashing effect of the V-type filter 4 is good. The V-type filter 4 adopts an advanced air-water combined flushing method, which can clean the filter material more thoroughly, and continuously sweep the surface during the backwashing process to discharge impurities more quickly;

[0046] 4. The V-type filter tank 4 has a high degree of automation and is easy to manage. Compared with the traditional ordinary rapid filter tank, the V-type filter tank 4 has a high degree of automation. Except for specific operations, no manual operation is required, which greatly reduces the risk of accidents caused by improper manual operation and saves labor time and labor.

[0047] 5. The process design of the V-type filter 4 achieves water saving, electricity saving and emission reduction, effectively reducing the operating costs for the water plant.

[0048] Working principle: The water purification process adopts flocculation sedimentation and V-type filtration. The raw water mixed with the coagulant enters the intelligent integrated water purification equipment. After being evenly distributed by the water distributor, it slowly enters the grid flocculation tank 9 for a thorough coagulation reaction to enlarge the flocs, and then enters the transition zone 91. Its function is to distribute water evenly to avoid the destruction of the formed flocs. A perforated wall is used to distribute water between the transition zone and the inclined tube sedimentation tank 6. A mud bucket is set at the bottom of the inclined tube. Under the action of the inclined tube, the particles in the water settle quickly, and the upper clear water flows from the separation area into the water collection tank and enters the V-type filter tank 4 through the outlet pipe. The sludge in the lower layer is concentrated at the bottom of the equipment and discharged regularly. The water flows through the quartz sand homogenized filter material layer and is filtered through full contact with the filter material to further remove small particle impurities that have not been precipitated in the sedimentation area to complete the purification. The effluent quality after disinfection must meet the requirements of the "National Drinking Water Quality Standard" (GB5749-2022).
