Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a sewage treatment system suitable for rivers. Background Art

[0002] The garbage and sewage generated in people's production activities are generally discharged directly into the river without being treated uniformly or without treatment, which causes a sharp increase in the nitrogen and phosphorus content in the river, thereby causing eutrophication of the water body and destroying the river ecosystem. Usually, when treating sewage in the river, the treatment agent (anionic polyacrylamide (PAM)) is sprinkled into the river water, so that the treatment agent is transported downstream along the water flow. The treatment agent combines with the sewage to degrade the pollutants in the sewage.

[0003] For example, the patent number CN216403881U discloses a sewage treatment system suitable for rivers, including a first motor and a second motor. In this scheme, the treatment agent is driven by the first motor to be transported and scattered in the river, and then the treatment agent and sewage are stirred by the second motor to drive the stirring mechanism. However, in actual use, it is found that: first, the treatment system is set up in the river, which increases the risk of connecting to the power supply, and is not energy-saving and environmentally friendly. Moreover, the stirring mechanism is set inside the river water, and there are garbage impurities in the water flowing through the river, which are easily entangled in the stirring mechanism. In addition, since the river water is flowing, if the treatment agent is continuously sprinkled, it will lead to extreme waste of materials. For this reason, a sewage treatment system suitable for rivers is proposed. Utility Model Content

[0004] In view of the problems existing in the existing sewage treatment systems of the above-mentioned rivers, the present utility model is proposed.

[0005] Therefore, the purpose of the utility model is to provide a sewage treatment system suitable for rivers, which solves the problems raised by the background technology.

[0009] Preferably, a lifting convex ball is fixedly provided on the lower surface of the slide plate, and the raised portion of the cam can be arranged in extrusion contact with the lifting convex ball.

[0010] Preferably, the discharge port is an inverted trapezoidal port, and the blocking block is an inverted trapezoidal block.

[0012] Furthermore, a stable support seat is fixedly provided at the lower end of the support sleeve.

[0013] Preferably, a feeding hopper is fixedly provided on the top of the storage box.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model is provided with a rotating shaft, a driving water wheel and a cam. When the river water flows, it can drive the driving water wheel to rotate. The driving water wheel drives the rotating shaft to rotate, so that the raised parts of the multiple cams on the rotating shaft push the blocking block upward. The blocking block can move upward from the inside of the discharge port. At this time, the treatment agent can leak out through the gap between the blocking block and the discharge port and be sprinkled into the river water. When the raised part of the cam is separated from the blocking block, the blocking block automatically falls down due to the elastic force and blocks the discharge port. When the raised part of the cam pushes the blocking block upward again and completes the intermittent discharge, the phenomenon of continuous addition of the treatment agent causing waste can be avoided.

[0016] 2. The utility model is provided with a slide plate, a slide rod and a spring. When the cam pushes the blocking block upward, the slide plate moves on the slide rod and stretches the spring. When the cam does not push the blocking block, the elastic force of the spring causes the slide plate to drive the blocking block to move downward quickly and block the discharge port.

[0017] 3. The utility model is provided with a supporting sleeve, a supporting rod and bolts. When the entire device system needs to be erected in a river channel, the bolts are first loosened, and the position between the supporting rod and the supporting sleeve is adjusted. The use height of the driving water wheel can be adjusted to contact with the surface of the river water, which can ensure that the flowing river water drives the driving water wheel to rotate.

When the river water flows, the driving water wheel 8 can drive the driving water wheel 8 to rotate, and the driving water wheel 8 drives the rotating shaft 7 to rotate, so that the protrusions of the plurality of cams 9 on the rotating shaft 7 push the blocking blocks 5 upward, and the blocking blocks 5 can move upward from the inside of the discharge port 4. At this time, the treatment agent (anionic polyacrylamide (PAM)) can leak out through the gap between the blocking blocks 5 and the discharge port 4 and be sprinkled into the river water, which can remove suspended matter in the water and accelerate particle sedimentation, thereby clarifying the water body. When the protrusion of the cam 9 is separated from the blocking block 5, the blocking block 5 automatically falls due to the elastic force and gravity and blocks the discharge port 4. When the protrusion of the cam 9 pushes the blocking block 5 upward again and completes the intermittent discharge, the phenomenon of continuous addition of the treatment agent causing waste is avoided.

[0027] In order to enable the blocking block 5 to quickly block the discharge port 4, Figure 1-2 As shown, elastic mechanisms are provided between the plurality of blocking blocks 5 and the bottom of the storage box 3, and the elastic mechanisms include a slide plate 10, a slide bar 11 and a spring 12.

When 9 pushes the blocking block 5 upward, the slide plate 10 moves on the slide rod 11 and stretches the spring 12. When the cam 9 does not push the blocking block 5, the elastic force of the spring 12 causes the slide plate 10 to drive the blocking block 5 to move downward quickly and block the discharge port 4; a lifting convex ball 13 is fixedly provided on the lower surface of the slide plate 10, and the convex portion of the cam 9 can be arranged in compression contact with the lifting convex ball 13. The lifting convex ball 13 is smoother when in contact with the cam 9, thereby ensuring a smoother push of the blocking block 5.

[0028] Finally, in order to be able to adjust the use height of the driving water wheel 8, as Figure 1As shown, the adjusting rod 2 includes a supporting sleeve 14 and a supporting rod 15. The upper end of the supporting rod 15 is fixedly connected to the lower surface of the supporting plate 1, and the lower end of the supporting rod 15 is plugged into the supporting sleeve 14. The tube wall of the supporting sleeve 14 is provided with a bolt 16, and the rod wall of the supporting rod 15 is provided with a screw hole 17 matching with the bolt 16. The lower end of the supporting sleeve 14 is fixedly provided with a stable supporting seat 18.
