Description

When the water level of the temporary storage pool 5 reaches the first overflow port 502, the stream water flows to the rotary bucket 601 through the overflow pipe 5021 on the first overflow port 502. 60. When the water level in the filter tank 102 is lower than the lowest point of the float 1022, the water level in the filter tank 102 is lower than the lowest point of the float 1022. 22 descends to close the water inlet pipe 1023. At this time, the water inlet pipes 1023 on both sides of the filter pool 102 are in a closed state. The stream water in the filter pool 102 flows from top to bottom, thereby cleaning the sewage receiving chamber 1024 of the filter pool. When the water level in the temporary storage pool 5 is lower than the first overflow port 502, no stream water flows into the rotary barrel 601. The rotary barrel 601 rotates to its original state due to the discharge of water in the barrel through the drain hole 6015 and the action of the balancing force.

The water level in the pool 10, when the stream water in the water reservoir 10 is full, the water level control valve 703 is closed to prevent the stream water in the sedimentation tank 7 from flowing into the water reservoir 10. In addition, a sedimentation tank sewage chamber 701 is provided at the bottom of the sedimentation tank 7, and the sedimentation tank sewage chamber 701 is connected to the cleaning pipe 4, and the cleaning pipe 4 is fixed on the cleaning pipe fixing frame 6041.

[0044] As a preferred implementation manner of this embodiment, a rotating barrel side plate 6014 is provided on the side of the rotating barrel 601, and a drainage hole 6015 is provided on the rotating barrel side plate 6014. The rotating barrel side plate 6014 is rotatably connected to the rotating barrel 601. By rotating the rotating barrel side plate 6014 and adjusting the height of the drainage hole 6015, the rotation time of the rotating barrel 601 can be controlled, thereby controlling the cleaning time of the filtration system.

[0045] Specifically, the filtered material 1026 in the filter tank 102 is coarse sand, coarse medium sand, medium sand, medium fine sand, activated carbon and fine sand in sequence from the water inlet tank 101 to the temporary storage tank.

[0046] Specifically, a floating object drainage pipe 9 is provided outside the floating object overflow port 2 , and floating objects flow through the floating object overflow port 2 to the floating object drainage pipe 9 and then flow to the outside.

[0047] As a preferred implementation of this embodiment, the cleaning pipe connection port 3 is arranged at the edge of the bottom of the filter system 1, and the bottom plate 103 at the bottom of the filter system 1 is inclined toward one side of the cleaning pipe connection port 3 to ensure the impact force of the stream water in the filter tank sewage cavity 1024. At the same time, the sewage in the filter tank sewage cavity 1024 can also be discharged cleanly to avoid residue.

[0048] Specifically, the float 1022 is a hollow structure, and the material of the float 1022 is stainless steel, which can prevent it from rusting in stream water for a long time and has a long service life.

[0049] Specifically, the opening 1021 on the water inlet pipe 1023 is lower than the floating object baffle 1028, ensuring that the floating object baffle 1028 is always above the opening 1021, preventing floating objects from flowing to the opening 1021 and entering the lower filter tank.

[0050] Specifically, the water-stopping ball 606 is made of stainless steel to prevent it from rusting in stream water for a long time.

[0051] Working principle: Stream water or river water enters the water inlet pool 101 through the stainless steel protective cover 1011, and enters the filter pool sewage cavity 1024 after being filtered by the stainless steel filter screen 1013. The stream water in the filter pool sewage cavity 1024 is filtered upward to the top of the filter pool 102 through the filter material 1026 on the filter plate 1025. The stream water enters the filter pool 102 of the next layer through the opening 1021 on the water inlet pipe 1023. The float 1022 in the water inlet pipe 1023 floats up, and the water inlet pipe 1023 is in a water-flowing state. The stream water passes through the filter pool 102 The purpose of removing impurities is achieved through layer-by-layer filtration. The water is stored in the temporary storage pool 5. When the water level in the temporary storage pool 5 reaches the first overflow port 502, the stream water flows into the rotary barrel 601 through the overflow pipe 5021 on the first overflow port 502. The rotary barrel 601 is initially in a slightly tilted state. After the stream water enters the rotary barrel 601, it flows to the lower end of the rotary barrel 601. When the weight of the stream water at the lower end of the rotary barrel 601 reaches a certain value, the rotary barrel 601 rotates, thereby driving the rotating shaft 602 to rotate. The rotating shaft 602 is fixedly connected to the adapter 6043. 6043 rotates, the adapter 6043 is fixedly connected to the push block fixing plate 6042, the push block fixing plate 6042 moves upward, and the push block 605 pushes the water stop ball 606 upward. At this time, the outlets of each cleaning pipe 4 are opened, and the stream water in the filter tank sewage cavity 1024 flows out to the cleaning pipe 4. When the water level in the filter tank 102 is lower than the lowest point of the float 1022, the float 1022 sinks and closes the water inlet pipe 1023. At this time, the water inlet pipes 1023 on both sides of the filter tank 102 are in a closed state, and the filter tank 102 The stream water in the temporary storage pool 5 flows from top to bottom, and then cleans the filter pool 102 and the filter pool sewage chamber 1024. When the water level in the temporary storage pool 5 is lower than the first overflow port 502, no stream water flows into the rotary barrel 601. Since the water in the rotary barrel flows out through the drain hole 6015 and the rotary barrel 601 is balanced by the counterweight block 6013, the rotary barrel rotates to its initial state. At this time, the push block 605 moves downward, and the water stop ball 606 blocks the outlet of the cleaning pipe 4. The cleaning pipe 4 is closed, and the filtration system changes from the cleaning state to the filtering state.
