[0002] In order to remove algae blooms, people have developed a variety of algae-water separation devices, such as rotary drum filters. The rotary drum filter usually includes a housing, in which a rotating cylinder is arranged. The cylinder is meshed, and the cylinder divides the housing into a sewage area inside the cylinder and a clean water area outside the cylinder. The algae water in the sewage area passes through the cylinder into the clean water area, and the algae therein are retained by the meshed cylinder. A backwash nozzle is arranged at the top of the housing to flush the algae on the inner wall of the cylinder into the collection tank in the middle of the cylinder. However, since most of the algae float in the water body, the amount of algae actually retained by the cylinder is very small, so that the solid content of the algae water backwashed into the collection tank is low, and the algae residue collection efficiency is low.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0026] First embodiment:

[0027] This embodiment discloses an algae-water separation device.

[0028] Figure 1 FIG. 1 is a schematic diagram of the structure of the algae-water separation device of the utility model. Figure 1 As shown, the algae-water separation device includes a separation box 1, a rotating drum 2, a driving component, a filter plate 22 and a collection tank 4.

[0029] like Figure 1 As shown, the separation box 1 is a hollow structure, including a water outlet 11, which is opened on the first surface of the separation box 1. The rotary drum 2 includes a filter cartridge 21 and a first water inlet 23. The cartridge surface of the filter cartridge 21 is a mesh body, and the filter cartridge 21 is rotatably arranged in the separation box 1. The first water inlet 23 is opened on the filter cartridge 21 and connected to the second surface of the separation box 1. The first surface is the right side of the separation box 1, and the second surface is the left side of the separation box 1.

[0030] Exemplarily, the filter cartridge 21 is horizontally arranged in the separation box 1. The mesh size of the cylinder surface is selected to be 200-350 meshes, which can achieve water permeability while retaining algae. The drum 2 divides the separation box 1 into an algae-water area inside the filter cartridge 21 and a clean water area between the filter cartridge 21 and the separation box 1. The first water inlet 23 enters the algae water, and the algae water passes through the filter cartridge 21 under the action of gravity. A small amount of algae is retained by the inner wall of the filter cartridge 21, and clean water enters the clean water area and is discharged from the water outlet 11. The separation box 1 includes an isolation plate 13 and a rolling member 14. The isolation plate 13 is arranged on the second side of the separation box 1, and a hole is opened in the middle of the isolation plate 13. The outer side of the rolling member 14 is fixedly connected to the hole, and the inner side of the rolling member 14 is rotatably connected to the second side of the filter cartridge 21. The rolling member 14 adopts a bearing structure.

[0031] like Figure 1 As shown, the drive assembly is arranged on the first surface of the separation box 1, and the output end of the drive assembly is drivingly connected to the first surface of the filter cartridge 21. Exemplarily, the drive assembly includes a motor 32 and a reducer 31. The reducer 31 is fixed to the second surface of the separation box 1, the first end of the reducer 31 is drivingly connected to the output end of the motor 32, and the second end of the reducer 31 is drivingly connected to the filter cartridge 21.

[0032] Figure 2 This is a schematic diagram of the structure of the separation box in the algae-water separation device of the utility model. Figure 1 and Figure 2 As shown, the filter plate 22 is a mesh body, having several meshes, which are arranged in an annular manner on the inner wall of the filter cartridge 21. Specifically, the filter plate 22 does not interfere with the surface of the tank body 41 of the collecting tank 4 when rotating, and the mesh number of the filter plate 22 is selected to be 200-350 meshes, which can achieve water permeability while retaining algae. When the filter plate 22 leaves the surface of the algae water area, the algae suspended in the algae water are retained and fished out by the filter plate 22, and the clean water returns to the algae water area. Preferably, the filter plate 22 includes a first part 221 and a second part 222. The first part 221 is connected to the inner wall of the filter cartridge 21, and the second part 222 is connected to the first part 221 at an angle toward the rotation direction of the filter cartridge 21. The inclined second part 222 prevents the algae from flowing back to the algae water area from the first part 221 too quickly with the algae water, thereby improving the efficiency of the filter plate 22 in collecting algae residues. Specifically, the angle a between the first portion 221 and the inner wall of the filter cartridge 21 is 30° to 160°, and the angle b between the second portion 222 and the first portion 221 is 120° to 160°.

[0033] like Figure 1 As shown, the collecting tank 4 passes through the first water inlet 23, and the part of the collecting tank 4 located in the filter cartridge 21 has an upward opening. Exemplarily, the collecting tank 4 includes a tank body 41 and a tube body 42. The position of the tank body 41 corresponds to the inner side of the filter cartridge 21, and has an upward opening. The tube body 42 passes through the first water inlet 23 to connect the tank body 41, is fixed in the slow flow box 6 and passes through the slow flow box 6. Preferably, the bottom of the tank body 41 is a U-shaped tube body, and the collecting tank 4 is arranged to be inclined upward relative to the horizontal plane, so as to improve the fluidity of the algae in the collecting tank 4 and prevent the algae from adhering to the inner surface of the collecting tank 4.

[0034] like Figure 1 As shown, further, the separation box 1 includes a support member 12. The lower end of the support member 12 is connected to the lower end of the separation box 1, and the upper end of the support member 12 is slidably connected to the surface of the filter cartridge 21. Exemplarily, a roller is rotatably provided on the upper end of the support member 12, and the roller is in sliding contact with the surface of the filter cartridge 21 to improve the stability of the middle part of the filter cartridge 21.

[0035] like Figure 1 and Figure 2 As shown, further, the separation box 1 includes a nozzle 15, a pump body and a return pipe 16. The nozzle 15 is arranged in the separation box 1, and the nozzle 15 sprays toward the outer cylinder surface of the filter cartridge 21 located below the tank body 41. The pump body is arranged at the lower end of the interior of the separation box 1, and the return pipe 16 connects the pump body and the nozzle 15. Specifically, the pump body draws the clean water in the clean water area into the return pipe 16, and the nozzle 15 sprays the clean water to flush the algae remaining on the inner surface of the filter cartridge 21 into the algae water area. At the same time, when the filter plate 22 passes through the injection path, the algae remaining on the filter plate 22 is also flushed back into the algae water area, and separated again, thereby increasing the solid content of the algae water in the algae water area again, further improving the efficiency of collecting algae residues, and preventing the algae residues from adhering to the filter plate 22 and the filter cartridge 21.

[0036] In this embodiment, the algae water enters the algae water area in the filter cartridge 21 through the first water inlet 23. During the rotation of the filter plate 22, the algae suspended in the algae water are retained and fished out by the filter plate 22, and the clean water returns to the algae water area. When the filter plate 22 rotates to the top of the filter cartridge 21, a large amount of algae hanging on the filter plate 22 and a small amount of algae on the inner surface of the filter cartridge 21 fall into the collection tank 4 under the action of gravity and are discharged. The algae discharged from the collection tank 4 has a high solid content, which improves the efficiency of collecting algae residue.

[0037] Second embodiment:

[0038] Based on the first embodiment, the second embodiment further optimizes and refines the first embodiment.

[0039] Figure 3 This is a schematic diagram of the structure of the flocculation box in the algae-water separation device of the utility model. Figure 1and Figure 3 As shown, the algae-water separation device includes a flocculation box 5. The flocculation box 5 is a hollow structure and is arranged at the lower end of the separation box 1. The flocculation box 5 includes a second water inlet 51 and a first baffle 52. The second water inlet 51 is arranged on the first surface of the flocculation box 5, and the first baffle 52 is staggered in the flocculation box 5. Exemplarily, after the flocculant is added, the algae water enters the flocculation box 5 through the second water inlet 51. The first baffle 52 is staggered up and down and left and right in the flocculation box 5. The algae water passes through the first baffle 52 for multiple diversions in the flocculation box 5 to improve the mixing effect of the algae and the flocculant.

[0040] like Figure 1 As shown, further, the algae-water separation device includes a slow flow box 6, which is a hollow structure, the lower end of which is connected to the upper end of the flocculation box 5, and the first surface is connected to the first water inlet 23. The slow flow box 6 includes a second baffle 61, and the second baffle 61 is arranged at the bottom of the inner side of the slow flow box 6. Exemplarily, the second baffle 61 divides the slow flow box 6 into an inverted U shape, increases the algae-water stroke, and prevents the liquid level in the separation box 1 from rising too fast, affecting the operation of the equipment. Preferably, a window is arranged on the side of the slow flow box 6 to facilitate observation of the flocculation situation.

[0041] like Figure 1 As shown, further, the separation box 1, the flocculation box 5 and the slow flow box 6 are provided with an emptying port 7 on the side to facilitate emptying the equipment for cleaning.

[0042] In the present embodiment, the algae water with added flocculants is passed through the flocculation box 5, and the first baffles 52 staggered in the flocculation box 5 guide the algae water, thereby increasing the flocculation reaction time and improving the flocculation effect of the algae. A slow flow box 6 is added above the flocculation box 5, and the second baffle 61 at the bottom of the slow flow box 6 divides the slow flow box 6 into an inverted U shape, thereby increasing the travel of the algae water and preventing the liquid level in the separation box 1 from rising too quickly, thereby affecting the operation of the equipment.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. 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 utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
