[0034] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0035] Example: A biological algae removal device for a filtration pond, see attached document. Figure 1 -Appendix Figure 7 The system includes a filter plate 1, a filter tube 5, a filter screen 51, side plates 2, and a bottom plate 3. The filter plate 1 is disposed inside the filter tank 10, vertically arranged and perpendicular to the length of the filter tank 10. The two sides of the filter plate 1 are respectively attached to the two inner walls of the filter tank 10, and the bottom of the filter plate 1 is attached to the bottom of the filter tank 10. The filter tube 5 is fixedly connected to the outside of the filter tank 10 and located at the bottom of one end of the filter tank 10, and the filter tube 5 is in communication with the filter tank 10. The filter screen 51 is fixedly connected to the end of the filter tube 5 away from the filter tank 10. The two side plates 2 are fixedly connected to the side of the filter plate 1 away from the filter tube 5, vertically arranged and perpendicular to the filter plate 1, and respectively attached to the two inner walls of the filter tank 10. The bottom plate 3 is fixedly connected to the side of the filter plate 1 away from the filter tube 5 and is attached to the bottom of the filter tank 10. The filter plate 1 can slide along the length of the filter tank 10 and can slide vertically. The filter plate 1 is provided with several filter holes, and the filter plate 1 is used to filter out algae organisms of a certain size.

[0036] Before filtration in the filter tank 10, the filter plate 1 moves from the end of the filter tank 10 near the filter pipe 5 to the end away from the filter pipe 5, filtering out large algae and concentrating them in the space enclosed by the side plates 2 and the bottom plate 3. Then, the filter plate 1 is pulled upward out of the filter tank 10. Under the constraint of the side plates 2 and the bottom plate 3, the filtered algae detaches upward from the filter tank 10, thereby reducing the pressure on the subsequent filter screen 51.

[0037] Specifically, this embodiment also includes a movable plate 4, which is parallel to the filter plate 1. The two sides of the movable plate 4 are attached to the two inner walls of the filter tank 10, and the bottom of the movable plate 4 is attached to the bottom of the filter tank 10. The movable plate 4 is disposed on the side of the filter plate 1 near the filter tube 5. The movable plate 4 is attached to the filter plate 1. The filter plate 1 can move up and down on the movable plate 4 and the movable plate 4 can slide along the length of the filter tank 10. The filter plate 1 is provided with a plurality of through holes 41 that penetrate the filter plate 1 in a direction perpendicular to the filter plate 1.

[0038] During use, the sliding of the movable plate 4 causes the filter plate 1 to slide along the length of the filter tank 10 within the filter tank 10.

[0039] Two vertically arranged sliding rods 11 are fixedly connected to the side of the filter plate 1 near the moving plate 4. Two vertically arranged sliding grooves 42 are provided on the side of the moving plate 4 near the filter plate 1. The two sliding rods 11 are located near the two sides of the filter plate 1 and are respectively embedded in the two sliding grooves 42, allowing the sliding rods 11 to slide vertically within the sliding grooves 42. The cross-sections of the sliding rods 11 and the sliding grooves 42 are convex, with the narrow side located on the side of the sliding rods 11 near the filter plate 1.

[0040] Specifically, a support frame 8 is provided inside the through hole 41. The support frame 8 is fixedly connected to the hole wall of the through hole 41. A rotating shaft 81 is rotatably connected to the support frame 8. The axis of the rotating shaft 81 is perpendicular to the moving plate 4. Several fan blades 82 are fixedly connected to the outside of the rotating shaft 81. The multiple fan blades 82 are arranged around the rotating shaft 81.

[0041] When the movable plate 4 moves, the water flowing through the through hole 41 will directly impact the fan blade 82, thereby driving the rotating shaft 81 to rotate. The rotation of the rotating shaft 81 will cause the fan blade 82 to disturb the water flow.

[0042] Specifically, the through holes 41 are provided in several groups, each group including multiple through holes 41. The multiple through holes 41 in the same group are arranged in the vertical direction, and the multiple groups of through holes 41 are arranged in the width direction of the filter tank 10.

[0043] Specifically, this embodiment also includes a supply pipe 7, a vertical pipe 71, and an outlet pipe 72. The supply pipe 7 is fixedly connected to the top of the movable plate 4 and is used to deliver the algaecide. Multiple vertical pipes 71 are provided and fixedly connected to the bottom of the supply pipe 7. Each vertical pipe 71 corresponds to a set of through holes 41, and the vertical pipe 71 is located on the side of the movable plate 4 away from the filter plate 1. The outlet pipe 72 is fixedly connected to the side of the vertical pipe 71 away from the movable plate 4, and each through hole 41 corresponds to one outlet pipe 72. The outlet pipe 72 has a corresponding through hole 41 located near the filter pipe 5.

[0044] The algaecide is delivered to the vertical pipe 71 through the supply pipe 7 and then discharged through the outlet pipe 72. The algaecide delivered through the outlet pipe 72 is evenly mixed in the wastewater after it has been filtered by the filter plate 1 under the disturbance of the fan blades 82, killing small algae in the wastewater and preventing the algae from continuing to grow.

[0045] Specifically, this embodiment also includes a baffle 6, which is disposed inside the filter tank 10 and fits against the inner wall of the filter tank 10 at the end away from the filter tube 5. The two sides of the baffle 6 are respectively embedded in the two inner walls on both sides of the filter tank 10 and can slide up and down on the filter tank 10. The side plate 2 is fixedly connected with a plurality of positioning protrusions 21 arranged in a vertical direction on the side near the baffle 6. The baffle 6 is provided with a plurality of positioning holes 61 on the side near the side plate 2. Each positioning protrusion 21 corresponds to a positioning hole 61. When the side plate 2 and the baffle 6 are fitted together, the positioning protrusions 21 are inserted into the corresponding positioning holes 61 and the bottom plate 3 is fitted together with the baffle 6 at this time.

[0046] By setting the positioning protrusion 21 and positioning hole 61, after the side plate 2 is attached to the baffle 6, the filter plate 1 will move the baffle 6 upward together during the upward movement process, so that the algae filtered by the filter plate 1 will not fall off the side of the bottom plate 3 away from the filter plate 1.

[0047] Specifically, this embodiment also includes a fixing frame 9, which is fixedly connected to both sides of the top of the filter tank 10; a connecting rod 43 is fixedly connected to the top of the movable plate 4, and a sliding groove 91 is provided on the side of the two fixing frames 9 near the connecting rod 43 along the length direction of the filter tank 10. The two ends of the connecting rod 43 are respectively inserted into the two sliding grooves 91. A lead screw 92 is rotatably connected to the fixing frame 9 in the sliding groove 91. The axis of the lead screw 92 is parallel to the length direction of the sliding groove 91. The lead screw 92 passes through the connecting rod 43 along its own length direction and is threadedly engaged with the connecting rod 43.

[0048] Specifically, a vertically sliding control plate 52 is provided at one end of the filter tank 10 near the filter tube 5. The control plate 52 is attached to the inner wall of the filter tank 10 near the filter tube 5 so as to control the switch of the filter tube 5 by sliding it up and down.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
