Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a tap water supply sedimentation tank. Background Art

[0002] The tap water supply relies on nearby water bodies and groundwater. After the water body undergoes impurity removal and sterilization processes, it is transported to various users through pressurized conveying equipment. However, due to the presence of certain particulate impurities in the raw water, it needs to be pumped into a sedimentation tank for coagulation before the sterilization process is performed. That is, liquid inorganic polymer coagulant is added to the sedimentation tank to quickly condense the particulate impurities through the liquid inorganic polymer coagulant to accelerate sedimentation.

When the coagulant pressurizing equipment is running, the liquid inorganic polymer coagulant is discharged into the collection box through the connecting hose. During the left and right movement of the discharge frame, the wide surface of the discharge frame actually has an impact effect on the water source, and after the water source passes between the discharge frames, it is diverted by the discharge frame, so that the water source in the area covered by the left and right movement of the discharge frame is cross-fluid fusion, thereby accelerating the mixing of the liquid inorganic polymer coagulant and the water source, and the coagulation effect is better.

[0030] After the sedimentation tank body 1 is filled with water, the discharge mechanism 6 works, the polymer flocculant is input into the feed cylinder 62, and enters the storage tray 66 along the feed cylinder 62, and then the second driving structure 65 drives the baffle 63 to rotate, the baffle 63 drives the feed cylinder 62 to rotate, the feed cylinder 62 drives the storage tray 66 to rotate, and the polymer flocculant in the storage tray 66 is thrown out from the discharge port 661 by the centrifugal force, and the polymer flocculant diffuses in all directions. At the same time, the rotation of the storage tray 66 has a driving effect on the water body, so that the water The body forms waves, which can accelerate the diffusion of the polymer flocculant. The linear moving mechanism 5 works, the first motor 531 drives the first transmission wheel 532 to rotate, the first transmission wheel 532 drives the second transmission wheel 533 to rotate through the transmission belt 534, the second transmission wheel 533 drives the first screw 51 to rotate, the first screw 51 makes the mounting seat 4 do linear motion, the mounting seat 4 drives the storage tray 66 to move in the water body, so that the discharge mechanism can throw the polymer flocculant in any shape of the sedimentation tank to purify the water body.

[0031] See also Figure 3 and Figure 4As shown, a connecting ring 67 is provided at the upper end of the storage tray 66, and a plurality of first discharging structures 68 are provided around the storage tray 66. The first discharging structure 68 includes a long discharging pipe 681, one end of the long discharging pipe 681 is axially connected to the discharging port 661, a first annular connecting frame 682 is sleeved on the long discharging pipe 681, a first elastic connecting arm 683 is provided on one side of the first annular connecting frame 682, one end of the first elastic connecting arm 683 is hinged to the first annular connecting frame 682, the other end of the first elastic connecting arm 683 is hinged to the connecting ring 67, a first counterweight block 684 is provided on the other side of the first annular connecting frame 682, a first hose 685 is provided in the long discharging pipe 681, one end of the first hose 685 extends into the long discharging pipe 681, and the other end of the first hose 685 extends into the discharging port 661.

[0032] When the storage tray 66 rotates, the first counterweight 684 is affected by the centrifugal force and moves outward. The first counterweight 684 pulls the long discharge pipe 681 to rotate, and the extended long discharge pipe 681 can stir the water. The first elastic connecting arm 683 provides support for the long discharge pipe 681. The discharge end of the long discharge pipe 681 is far away from the discharge port 661. The polymer flocculant is thrown out from the discharge end of the long discharge pipe 681, so that the polymer flocculant is thrown to a farther range, so that the polymer flocculant can be mixed with the water near the sedimentation tank body 1 more quickly.

[0033] See also Figure 3 and Figure 4 As shown, a plurality of second discharging structures 69 are also arranged around the storage tray 66, and the second discharging structure 69 includes a short discharging pipe 691, one end of which is axially connected to the discharging port 661, and a second annular connecting frame 692 is sleeved on the short discharging pipe 691, and a second elastic connecting arm 693 is arranged on one side of the second annular connecting frame 692, one end of the second elastic connecting arm 693 is hinged to the second annular connecting frame 692, and the other end of the second elastic connecting arm 693 is hinged to the connecting ring 67, and a second counterweight block 694 is arranged on the other side of the second annular connecting frame 692, and a second hose 695 is arranged in the short discharging pipe 691, one end of the second hose 695 extends into the long discharging pipe 681, and the other end of the second hose 695 extends into the discharging port 661.

[0034] The polymer flocculant is discharged from the long discharge pipe 681, and the polymer flocculant cannot be discharged between the discharge end of the long discharge pipe 681 and the storage tray 66. By setting the second discharge structure 69, when the storage tray 66 rotates, the second counterweight block 694 is acted upon by centrifugal force, pulling the short discharge pipe 691 to rotate, and the discharge end of the short discharge pipe 691 is located between the discharge end of the long discharge pipe 681 and the storage tray 66, thereby achieving the discharge of polymer flocculant from both the proximal and distal ends of the discharge tray.

[0035] See also Figure 2 and Figure 5 As shown, a rolling structure 64 is arranged between the baffle 63 and the connecting frame 61, and the rolling structure 64 includes an inner ring body 641, an outer ring body 642 and a second roller 643. The inner ring body 641 and the outer ring body 642 are coaxially arranged, and there are several second rollers 643, and the several second rollers 643 are arranged in a circular array between the inner and outer ring bodies 642 and the outer ring body 642.

[0036] The second driving structure 65 drives the baffle 63 at a faster speed, which aggravates the wear between the baffle 63 and the connecting frame 61. By setting the rolling structure 64, the second roller 643 is tangent to the connecting frame 61 and the baffle 63. When the baffle 63 rotates, it drives a plurality of second rollers 643 to rotate. The second rollers 643 rotate on the connecting frame 61, so that the sliding friction between the baffle 63 and the connecting frame 61 is converted into rolling friction, thereby reducing the wear between the baffle 63 and the connecting frame 61 and increasing the service life of the baffle 63 and the connecting frame 61.

[0037] See also Figure 3 and Figure 6 As shown, the second driving structure 65 includes an outer gear ring 651, which is sleeved on the baffle 63. A second motor 652 is arranged at the upper end of the mounting seat 4. A driving gear 653 is arranged at the output end of the second motor 652. The driving gear 653 is connected to the output shaft of the second motor 652. A first driven gear 654 is arranged on one side of the driving gear 653. A second driven gear 655 is arranged on one side of the outer gear ring 651. A transmission shaft 656 is arranged between the first driven gear 654 and the second driven gear 655.

[0038] The second motor 652 works to drive the driving gear 653 to rotate, the driving gear 653 drives the first driven gear 654 to rotate, the first driven gear 654 drives the transmission shaft 656 to rotate, the transmission shaft 656 drives the second driven gear 655 to rotate, the second driven gear 655 drives the outer gear ring 651 to rotate, and the outer gear ring 651 drives the baffle 63 to rotate. Since there are many impurities in the water, it is easy to corrode the second motor 652. Therefore, the second motor 652 is arranged at the upper end of the mounting seat 4, so as to avoid the second motor 652 from contacting with the water and improve the service life of the second motor 652.

[0039] See also Figure 7 As shown, a spiral blade 621 is disposed inside the feeding cylinder 62 .

[0040] The rotation speed of the feed barrel 62 is relatively fast. When the polymer flocculant is fed toward the feed barrel 62, the polymer flocculant will be thrown out from the upper end of the feed barrel 62 due to the centrifugal force. By arranging a spiral blade 621 in the feed barrel 62, the spiral direction of the spiral blade 621 is opposite to the rotation direction of the feed barrel 62. The polymer flocculant is fed into the feed barrel 62, and is tightly attached to the inner wall of the feed barrel 62 due to the centrifugal force, and is fed downward along the spiral blade 621 to the discharge tray, thereby preventing the polymer flocculant from being thrown out from the upper end of the clinker barrel.

[0041] See also Figure 2 and Figure 8 As shown, both ends of the first screw 51 are provided with a lifting mechanism 7, and the lifting mechanism 7 includes a third motor 71. The third motor 71 is arranged at the upper end of the auxiliary pool 2, and a second screw 72 is arranged at the output end of the third motor 71. The second screw 72 is provided with a screw sleeve 73, one end of the screw sleeve 73 is connected to the second screw 72, and the other end of the screw sleeve 73 is connected to the first screw 51.

[0042] When the water level in the sedimentation tank body 1 is low, the two third motors 71 work at the same time, driving the two second screws 72 to rotate. Since the two screw sleeves 73 cannot rotate, the two screw sleeves 73 move along the two second screws 72 respectively, so that the height of the first screw 51 is reduced, and the storage tray 66 is extended into the water body, thereby purifying water bodies with different water levels.

[0043] See also Figure 3 and Fig. 9 As shown, tensioning structures 535 are provided on both sides of the transmission belt 534, and the tensioning structure 535 includes an insert block 5351, which is connected to the auxiliary pool 2, a guide sleeve 5352 is provided on one side of the insert block 5351, a guide column 5353 is slidably provided in the guide sleeve 5352, a wheel frame 5354 is provided at one end of the guide column 5353, a first roller 5355 is provided on the wheel frame 5354, a first pressure spring 5356 is sleeved on the guide sleeve 5352, one end of the first pressure spring 5356 is connected to the insert block 5351, and the other end of the first pressure spring 5356 is connected to the wheel frame 5354.

[0044] When the first screw rod 51 moves toward the direction approaching the first motor 531, the distance between the first transmission wheel 532 and the second transmission wheel 533 is reduced, and the length of the transmission belt 534 cannot be changed, so that the transmission belt 534 is loose and cannot be transmitted. Therefore, a tensioning structure 535 is provided, and the first pressure spring 5356 applies a thrust to the wheel frame 5354, and the guide column 5353 moves along the guide sleeve 5352. The first roller 5355 is tangent to the transmission belt 534. Both sides of the transmission belt 534 are acted upon by the tensioning structure 535 and shrink toward the middle, so that the transmission belt 534 between the first transmission wheel 532 and the second transmission wheel 533 remains in a tensioned state, so that the power of the first motor 531 can always be transmitted to the first screw rod 51.

[0045] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
