[0001] The invention relates to the field of water treatment, in particular to a rural high-turbidity raw water purification system. Background Art

High turbidity raw water usually contains a large amount of suspended impurities such as silt, suspended matter and microorganisms. These particles pose challenges to water quality and water treatment processes.

However, most of the existing devices are difficult to filter and separate the impurities in the raw water, resulting in insufficient raw water filtration and separation effects. In addition, most of the existing devices are difficult to fully clean the inside of the filter frame, resulting in more impurities accumulated on the filter frame, which slows down the filter frame's filtration speed for raw water, and thus makes the raw water purification effect insufficient.

[0015] The present invention has the following advantages: 1.

When the impurities rotate to the discharge port of the shell, the impurities will be thrown into the collection box and fall on the bottom plate; the rotation of the stirring frame will drive the raw water at the bottom of the shell to rotate along the inner wall of the shell, and the raw water rotates along the inner wall of the shell to generate centrifugal force to throw the flocculants onto the inner wall of the shell, and the flocculants slide down along the inner wall of the shell into the storage box under the action of gravity; the filter frame will filter the impurities remaining in the raw water, and the relatively clean raw water pumped away by the water pump will be discharged into the sedimentation tank through the water pipe; the filter screen first filters and separates the large impurities in the raw water, and then the stirring frame rotates to separate the flocculants and the raw water, and finally the residual impurities are filtered by the filter frame, and the raw water is filtered and separated by multiple layers, thereby making the purification effect of the raw water better.

[0016] 2. The downward movement of the movable plate will enlarge the space above the movable plate and the filter frame, and the raw water will enter the space above the filter frame and the movable plate. The upward movement of the movable frame and the movable plate will squeeze the raw water above the movable plate, causing the raw water to move outward from the filter frame.

At the same time, the outward movement of the knocking rod will drive the extension rod to move outward, and the outward movement of the extension rod will knock the bottom of the shell, causing the bottom of the shell to vibrate. The vibration generated by the shell will vibrate the flocculants accumulated at the bottom of the shell, causing the flocculants in the shell to quickly fall into the storage box, thereby making the raw water in the shell cleaner.

[0036] The filtering mechanism includes a collecting box 71, a bottom plate 72, bolts 721, a filter screen 73 and a filter frame 74. The collecting box 71 is welded to the outside of the shell 2. A discharge port is opened on the shell 2. The discharge port of the shell 2 is connected to the collecting box 71. A bottom plate 72 is clamped at the bottom of the collecting box 71. Two bolts 721 are threadedly connected between the bottom plate 72 and the collecting box 71. A filter screen 73 is welded on the stirring frame 65. The filter frame 74 is fixedly connected to the bottom of the conduit 51.

[0037] The filter screen 73 is used to filter large impurities, and the filter frame 74 is used to filter small impurities.

[0038] Initially, the delivery pump 3 is connected with a medicine delivery pipe. The staff starts the delivery pump 3, the industrial control computer 41, the turbidity detector 4, the water pump 52 and the drive motor 62. The raw water enters the shell 2 through the water inlet of the shell 2. When the raw water passes through the water inlet of the shell 2, it passes through the turbidity detector 4. The turbidity detector 4 detects the turbidity of the raw water. The turbidity detector 4 transmits the detected data to the industrial control computer 41. The industrial control computer 41 controls the delivery pump 3 to add a suitable amount of medicine to the raw water according to the data of the turbidity detector 4. The raw water and the medicine enter the shell 2. The raw water and the medicine flow toward the bottom of the shell 2 and the storage box 54. When the raw water and the medicine flow downward, they pass through the filter screen 73. The large impurities in the raw water are intercepted by the filter screen 73. The agent flows to the bottom of the shell 2 and the storage box 54 and will cover the filter frame 74; at the same time, the output shaft of the driving motor 62 will drive the rotating shaft 63 and the gear 64 to rotate, the rotation of the gear 64 will drive the gear ring 66 to rotate, the rotation of the gear ring 66 will drive the stirring frame 65 and the filter screen 73 to rotate, the rotation of the filter screen 73 will throw the large impurities on the filter screen 73 onto the inner wall of the shell 2, and at the same time, the rotation of the filter screen 73 will drive the impurities on the filter screen 73 to rotate, and when the impurities rotate to the discharge port of the shell 2, the impurities will be thrown into the collection box 71 and fall onto the bottom plate 72, the rotation of the stirring frame 65 will stir the raw water and the agent at the bottom of the shell 2, so that the raw water and the agent at the bottom of the shell 2 are fully mixed, the agent will absorb the suspended impurities in the raw water into larger particles of floccules, and the stirring frame The rotation of 65 will drive the raw water and the reagent at the bottom of the shell 2 to rotate along the inner wall of the shell 2. The raw water rotates along the inner wall of the shell 2 to generate centrifugal force to throw the floccules onto the inner wall of the shell 2, and the floccules slide down along the inner wall of the shell 2 into the storage box 54 under the action of gravity. At the same time, the water pump 52 pumps away the relatively clean raw water in the middle of the shell 2 through the conduit 51 and the filter rack 74. The filter rack 74 will filter the impurities remaining in the raw water. The relatively clean raw water pumped away by the water pump 52 will be discharged into the sedimentation tank 1 through the water pipe 53. The raw water is precipitated and sterilized in the sedimentation tank 1. After the purification of the raw water is completed, the staff turns off the delivery pump 3, the industrial control computer 41, the turbidity detector 4, the water pump 52 and the drive motor 62, and the delivery pump 3 stops moving. After adding the reagent, the water pump 52 is turned off and no longer pumps water, the rotating shaft 63, the gear 64, the stirring frame 65 and the gear ring 66 stop rotating, and the staff starts the discharge pump 55, and the discharge pump 55 discharges the impurities collected in the storage box 54. After the impurities in the storage box 54 are discharged, the staff turns off the discharge pump 55, and finally the staff loosens the bolts 721 to remove the bottom plate 72, and the large impurities in the collection box 71 will fall. The staff then installs the bottom plate 72 and tightens it with the bolts 721. The filter screen 73 first filters and separates the large impurities in the raw water, and then the stirring frame 65 rotates to separate the flocculants and the raw water, and finally the filter frame 74 filters the remaining impurities. Through multi-layer filtration and separation of the raw water, the purification effect of the raw water is improved.

[0039] Embodiment 2: Based on embodiment 1, Figure 8-Figure 10 As shown, a cleaning mechanism is also included, which includes a connecting rod 81, a reducer 82, a movable frame 83, a bidirectional screw rod 84, a rotating ring 85 and a movable plate 87. Three connecting rods 81 are welded on the stirring frame 65, and a reducer 82 is welded to the three connecting rods 81. The movable frame 83 is slidably connected to the filter frame 74, and a guide hole is opened on the movable frame 83. The filter frame 74 is connected to the conduit 51 through the guide hole of the movable frame 83. A bidirectional screw rod 84 is welded to the bottom of the movable frame 83, and a rotating ring 85 is threadedly connected to the bidirectional screw rod 84. The rotating ring 85 is fixedly connected to the reducer 82. A movable plate 87 is welded on the movable frame 83, and the movable plate 87 is located in the filter frame 74. The movable plate 87 is slidably connected to the filter frame 74.

[0040] The movable plate 87 is used to squeeze the raw water to clean the filter frame 74 .

[0041] Initially, the filter frame 74 is connected to the conduit 51 through the guide hole of the movable frame 83, the stirring frame 65 drives the connecting rod 81 to rotate, the rotation of the connecting rod 81 drives the rotating ring 85 to rotate through the reducer 82, the speed reduction of the reducer 82 causes the rotating ring 85 to rotate slowly, the slow rotation of the rotating ring 85 squeezes the thread of the bidirectional screw rod 84 to make the bidirectional screw rod 84 reciprocate up and down, the up and down reciprocating movement of the bidirectional screw rod 84 drives the movable frame 83 and the movable plate 87 to reciprocate up and down, the movable frame 83 and the movable plate 87 move downward, the downward movement of the movable plate 87 causes the upper part of the movable plate 87 to be connected to the filter frame The space 74 becomes larger, and the raw water enters the space above the filter frame 74 and the movable plate 87. The upward movement of the movable frame 83 and the movable plate 87 will squeeze the raw water upward on the movable plate 87, causing the raw water to move toward the outside of the filter frame 74. When the filter frame 74 filters the raw water, some impurities will be stuck on the filter frame 74. The raw water in the filter frame 74 moves toward the outside of the filter frame 74, which will push the impurities stuck on the filter frame 74, causing the impurities stuck on the filter frame 74 to fall off the filter frame 74, thereby making the filter frame 74 cleaner, and thereby enabling the filter frame 74 to filter and purify the raw water more efficiently, and so on.

[0042] Embodiment 3: Based on embodiment 2, Figure 11-13As shown, a vibration mechanism is also included, which includes a rotating block 91, a connecting ring 92, a guide frame 93, a knocking rod 94 and an extension rod 95. The rotating block 91 is welded on the stirring frame 65, and a connecting ring 92 is welded on the bottom of the filter frame 74. The guide frame 93 is fixedly connected to the rotating ring 85, and a guide groove is opened on the guide frame 93. A plurality of knocking rods 94 are slidably connected to the rotating block 91, and the plurality of knocking rods 94 are used to knock the connecting ring 92. The plurality of knocking rods 94 are slidably connected to the guide groove of the guide frame 93, and the plurality of knocking rods 94 are respectively fixedly connected to the extension rods 95, and the plurality of extension rods 95 are used to knock the bottom of the shell 2.

[0043] The slow rotation of the rotating ring 85 will drive the guide frame 93 to rotate slowly, and the stirring frame 65 will drive the rotating block 91, the knocking rod 94 and the extension rod 95 to rotate at high speed. The knocking rod 94 will be driven by the centrifugal force to move along the guide groove of the guide frame 93 when it rotates at high speed. The knocking rod 94 will move outward when it rotates at high speed to the outer convex part of the guide groove, and then the knocking rod 94 will knock the connecting ring 92, so that the connecting ring 92 vibrates, and the slow rotation of the guide frame 93 causes the outer convex part of the guide groove to rotate slowly, so that the knocking rod 94 evenly knocks at each position of the connecting ring 92, and the vibration generated by the connecting ring 92 is transmitted to the filter frame 7 4. The vibration shakes off the impurities on the filter frame 74, and the filter frame 74 is cleaned more fully, so that the filter frame 74 can better purify the raw water. The knocking rod 94 continues to rotate and is guided by the guide groove of the guide frame 93 to move toward the center position of the rotating block 91. At the same time, the knocking rod 94 moves outward to drive the extension rod 95 to move outward. The extension rod 95 moves outward to knock the bottom of the shell 2, causing the bottom of the shell 2 to vibrate. The vibration generated by the shell 2 will vibrate the flocculants accumulated at the bottom of the shell 2, causing the flocculants in the shell 2 to quickly fall into the storage box 54, thereby making the raw water in the shell 2 cleaner, and then repeat this process.

[0044] Embodiment 4: Based on the embodiment 3, Figure 8 As shown, a brush 10 is also included. The brush 10 is welded on the stirring frame 65 , and the brush 10 is in contact with the filter frame 74 .

[0045] The stirring frame 65 will drive the brush 10 to rotate, and the rotation of the brush 10 will clean the outer wall of the filter frame 74, so that the filter frame 74 can better filter and purify the raw water.

[0046] Embodiment 5: Based on Embodiment 4, Figure 2 As shown, a guide frame 11 is also included, and the guide frame 11 is welded inside the storage box 54.

[0047] The floccules at the bottom of the shell 2 will fall into the storage box 54, and the floccules will fall to the bottom of the storage box 54 through the guide frame 11. When the guide frame 11 and the stirring frame 65 rotate, the water flow in the shell 2 will be driven to rotate. The guide frame 11 can separate the storage box 54 into two layers, so that the floccules at the bottom of the storage box 54 are not easy to rotate with the water flow, so that the floccules can be better settled at the bottom of the storage box 54, thereby reducing the probability of impurities returning to the shell 2, and thus better separating impurities in the water.
