The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] A water quality impurity removal and water-saving purification device for a hydraulic project according to an embodiment of the present invention will be described below in conjunction with the accompanying drawings.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, a water quality impurity removal and water-saving purification device for a water conservancy project according to an embodiment of the present invention may include a base 1, a barrel 2, a filter component 3, a sedimentation component 4, a disinfection component 5, a servo motor 6 and a linkage component 7.

[0031] The barrel body 2 is arranged on the base 1, and the interior of the barrel body 2 is divided into a top layer 21, a compartment 22, a middle layer 23 and a bottom layer 24. Water pipes 221 are arranged on both sides of the compartment 22, and the water pipes 221 connect the top layer 21 and the middle layer 23. A through opening 25 is opened on the side of the barrel body 2.

[0032] It should be noted that the size of the through opening 25 is larger than the size of the transmission structure 26 , so that the transmission structure 26 can move in the through opening 25 easily, so that the cleaning rod 443 can abut against the filter membrane 41 .

[0033] like Figure 1 and Figure 8 As shown, two transmission structures 26 are also provided on the barrel body 2 , and the transmission structure 26 includes a placement frame 261 , a driving gear 262 , a driven gear 263 and a toothed belt 264 .

[0034] The driving gear 262 , the driven gear 263 and the toothed belt 264 are all arranged in the placement frame 261 , and the toothed belt 264 is sleeved outside the driving gear 262 and the driven gear 263 .

[0035] It should be noted that the output end can drive the driven gear 263 to move through the driving gear 262 and the toothed belt 264 , thereby driving the stirring structure 44 and the water retaining structure 42 .

[0036] like Figure 1 and Figure 7 As shown, the upper transmission structure 26 is movably disposed in the through opening 25 and is connected to the compartment 22 via a support structure 27 . The support structure 27 includes a limit rod 271 and a moving rod 272 .

[0037] The limiting rod 271 is disposed below the placing frame 261 , and the moving rod 272 is connected to the placing frame 261 and slides in the limiting rod 271 .

[0038] It should be noted that the support structure 27 can ensure the stability of the transmission structure 26, facilitate its up and down movement, and further support and fix the stirring structure 44.

[0039] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the transmission structure 26 below is arranged on the top of the bottom layer 24 and extends to the outside of the barrel body 2. A water inlet 28 is arranged on the top of the barrel body 2, and a water outlet 29 is arranged on the bottom. A valve 210 is arranged on the water outlet 29. A movable groove 211 is opened in the side wall of the barrel body 2. A feed port 212, a waste outlet 213 and a slide 214 connected to the movable groove 211 are opened on the side of the barrel body 2. A barrier assembly 215 is arranged next to the slide 214. The barrier assembly 215 includes a baffle 2151, a movable block 2152, a mounting block 2153, a rotating rod 2154 and a limit block 2155.

[0040] Among them, the baffle 2151 is slidably set in the movable groove 211, the movable block 2152 is connected to the baffle 2151 and is slidably set in the slide groove 214, the mounting block 2153 is set on one side of the slide groove 214, the rotating rod 2154 is rotatably set on the mounting block 2153, and the limit block 2155 is rotatably set on the top of the rotating rod 2154.

[0041] It should be noted that the moving block 2152 can be pushed to slide in the slide groove 214. When the moving block 2152 moves, it will drive the baffle 2151 to slide in the moving groove 211. When the baffle 2151 moves to a suitable position, the limit block 2155 can be rotated. The limit block 2155 will drive the rotating rod 2154 to rotate to the bottom of the moving block 2152, and the baffle 2151 is lifted and fixed by the moving block 2152.

[0042] like Figure 1 As shown, a feeding box 216 is disposed on the outer shell of the feeding port 212 , and a placement table 217 is disposed on the opposite side of the feeding box 216 .

[0043] It should be noted that the servo motor 6 is placed on the placement table 217 .

[0044] like Figure 3 As shown, the filter assembly 3 is arranged in the top layer 21 , and the filter assembly 3 includes a filter box 31 , a porcelain sand layer 32 , an activated carbon layer 33 , a quartz sand layer 34 and filter paper 35 .

[0045] The porcelain sand layer 32 , the activated carbon layer 33 and the quartz sand layer 34 are sequentially arranged in the filter box 31 from top to bottom, and the filter paper 35 is interspersed among the porcelain sand layer 32 , the activated carbon layer 33 and the quartz sand layer 34 .

[0046] It should be noted that, through the porcelain sand layer 32, the activated carbon layer 33 and the quartz sand layer 34, as well as the filter paper 35 interspersed among the three, larger foreign matter in the water body can be preliminarily processed, reducing the difficulty of subsequent purification work.

[0047] like Figure 3 As shown, the sedimentation assembly 4 includes a filter membrane 41 , a water retaining structure 42 , a drive motor 43 and a stirring structure 44 .

[0048] The filter membrane 41 is arranged at the bottom of the middle layer 23 , the water retaining structure 42 is arranged at the bottom of the filter membrane 41 and abuts against the filter membrane 41 , and the water retaining structure 42 includes a fixed plate 421 , a movable plate 422 , a first screw 423 and a first slider 424 .

[0049] Among them, Figure 7As shown, the fixed plate 421 is arranged below the filter membrane 41, and a drainage hole 4211 is opened in the fixed plate 421, the movable plate 422 is connected to the first slider 424, and a locking block 4221 is arranged at a position corresponding to the movable plate 422 and the drainage hole 4211, the driving end of the first lead screw 423 is connected to the driven gear 263 of the transmission structure 26 located below, and the first slider 424 is slidably arranged on the first lead screw 423.

[0050] It should be noted that the size of the movable plate 422 is smaller than that of the fixed plate 421, which facilitates the water to flow out from the side. The locking block 4221 is trapezoidal and can cooperate with the drainage hole 4211 to control whether the water flows and the amount of water flow, thereby facilitating the control of the purification process.

[0051] like Figure 1 As shown, the drive motor 43 is disposed on the upper transmission structure 26 , and the output end is connected to the transmission structure 26 .

[0052] like Figure 3 As shown, the stirring structure 44 is disposed in the barrel body 2 and connected to the output end of the transmission structure 26 above. The stirring structure 44 includes a rotating shaft 441 , a stirring shaft 442 , a cleaning rod 443 and a magnetic block 444 .

[0053] Among them, one end of the rotating shaft 441 is connected to the driven gear 263 of the transmission structure 26 located above, and the other end extends downward to the middle layer 23. Several stirring shafts 442 are arranged on the rotating shaft 441, and the cleaning rod 443 is arranged at the bottom of the rotating shaft 441. The cleaning rod 443 is in the shape of a triangular prism, and the magnetic block 444 is arranged in the stirring shaft 442.

[0054] It should be noted that the driving motor 43 will drive the rotating shaft 441 through the transmission structure 26, and then drive the stirring shaft 442 and the cleaning rod 443 to rotate. While the stirring structure 44 accelerates the mixing of the reactants and the water body, it can also adsorb metal particles in the water source through the magnetic suction block 444.

[0055] like Figure 1 As shown, the disinfection component 5 is arranged on the base 1 and is connected to the barrel body 2. The disinfection component 5 includes an ozone generator 51, an air pump 52 and an air pipe 53.

[0056] The ozone generator 51 is arranged on the base 1 , the air pump 52 is arranged between the ozone generator 51 and the barrel body 2 , and the air pipe 53 connects the ozone generator 51 , the air pump 52 and the barrel body 2 .

[0057] It should be noted that the air pump 52 will deliver the ozone generated by the ozone generator 51 into the bottom layer 24 through the air pipe 53, and the ozone will be mixed with the water for the final disinfection treatment.

[0058] like Figure 1 As shown, the servo motor 6 is disposed on the placement platform 217 , and the servo motor 6 is connected to the water retaining structure 42 via the transmission structure 26 below.

[0059] like Figure 1 and Figure 2 As shown, the linkage assembly 7 is arranged on the output end of the servo motor 6 and connected to the upper transmission structure 26 . The linkage assembly 7 includes a second lead screw 71 , a second slider 72 and a connecting plate 73 .

[0060] The second lead screw 71 is disposed on the output end of the servo motor 6 , the second slider 72 is slidably disposed on the second lead screw 71 , and both ends of the connecting plate 73 are respectively connected to the second slider 72 and the transmission structure 26 above.

[0061] It should be noted that when the servo motor 6 drives the second screw 71 to rotate, the second slider 72 will slide, and the second slider 72 will drive the placement frame 261 located above to move downward in the opening 25 through the connecting plate 73, thereby driving the stirring structure 44 to move downward, and finally making the cleaning rod 443 abut against the filter membrane 41.

[0062] When the servo motor 6 controls the opening and closing of the water retaining structure 42 , it also drives the transmission structure 26 above through the linkage assembly 7 , that is, drives the stirring structure 44 to move.

[0063] It should be noted that, through the linkage assembly 7, the water discharge and the movement of the cleaning rod 443 can be performed simultaneously, which facilitates the next step and reduces the interference between the various steps.

[0064] Specifically, when the water body needs to be purified, the water body is first added to the top layer 21 of the barrel body 2 from the water inlet 28. The water body will flow through the porcelain sand layer 32, the activated carbon layer 33 and the quartz sand layer 34 of the filter component 3 in sequence, as well as the filter paper 35 interspersed among the three. In this way, larger foreign matter in the water body can be preliminarily processed, reducing the workload of subsequent purification work. Then the water body will continue to flow into the middle layer 23 from the water pipe 221.

[0065] At this time, reactants are added to the feeding box 216 and the drive motor 43 is started. The reactants will enter the middle layer 23 of the barrel 2 from the feed port 212 and mix with the water. The drive motor 43 will drive the driven gear 263 to rotate through the driving gear 262 and the toothed belt 264. The driven gear 263 will drive the rotating shaft 441, and then drive the stirring shaft 442 and the cleaning rod 443 to rotate. While accelerating the mixing of the reactants and the water, the stirring structure 44 can also adsorb metal particles in the water source through the magnetic block 444 to enhance the purification effect. When the reactants and the water source have fully reacted, the drive motor 43 is turned off and sediment will be generated in the water.

[0066] At this time, the servo motor 6 is started, and the servo motor 6 will drive the first screw 423 through the transmission structure 26, and at the same time drive the second screw 71 on the output end, the first screw 423 will drive the first slider 424 to move, and the first slider 424 will continue to drive the movable plate 422 to move, when the locking block 4221 on the movable plate 422 is staggered with the drainage hole 4211 on the fixed plate 421, the water can continue to flow into the bottom layer 24, and the sediment will remain on the filter membrane 41, and the second screw 71 will cause the second slider 72 to slide when it rotates, and the second slider 72 will drive the placement frame 261 located above to move downward in the through port 25 through the connecting plate 73, thereby driving the stirring structure 44 to move downward, and when the cleaning rod 443 abuts against the filter membrane 41, the servo motor 6 is turned off.

[0067] After waiting for all the water to enter the bottom layer 24, start the drive motor 43, the ozone generator 51 and the air pump 52. The drive motor 43 will drive the cleaning rod 443 to clean the filter membrane 41. The air pump 52 will send the ozone generated by the ozone generator 51 into the bottom layer 24 through the air pipe 53. The ozone will be mixed with the water for the final disinfection treatment. After the disinfection treatment is completed, the water can be discharged from the water outlet 29.

[0068] While waiting for disinfection, the moving block 2152 can be pushed to slide in the slide groove 214. When the moving block 2152 moves, it will drive the baffle 2151 to slide in the moving groove 211. When the bottom of the baffle 2151 is offset from the waste outlet 213, the limit block 2155 is rotated. The limit block 2155 will drive the rotating rod 2154 to rotate to the bottom of the moving block 2152. The baffle 2151 is lifted and fixed by the moving block 2152 to ensure that the waste outlet 213 is always in a smooth state. At this time, the sediment will be discharged from the waste outlet 213 under the action of the cleaning rod 443.

[0069] In summary, according to an embodiment of the present invention, a water quality impurity removal and water-saving purification device for a water conservancy project can achieve multi-stage purification of the water body through the cooperation of a filtering component, a sedimentation component and a disinfection component, thereby ensuring the purification effect. Through the linkage component, the disinfection and cleaning links can be separated, and the scraped sediment can be discharged from the side, ensuring the cleaning effect while not affecting the normal progress of the water purification work.
