[0025] Example:
[0026] This embodiment discloses an algae-water separation system.
[0027] Figure 1 The schematic diagram of the structure of the flocculation box, slow flow box and separation box in the algae-water separation system of the utility model is shown in FIG. Figure 1 As shown, the algae-water separation system includes a flocculation tank 5 , a slow flow tank 6 and a separation tank 1 .
[0028] Figure 2 The schematic diagram of the structure of the flocculation box in the algae-water separation system of the utility model is shown in FIG. Figure 1 and Figure 2 As shown, the flocculation box 5 is a hollow structure, and the first surface has a first water inlet 51. Exemplarily, the first surface is the right side of the flocculation box 5, and the second surface is the left side of the flocculation box 5. The flocculation box 5 includes a first baffle 52, which is staggered in the flocculation box 5 up and down and left and right. The algae water passes through the first baffle 52 for multiple diversions in the flocculation box 5, thereby improving the mixing effect of the algae and the flocculant.
[0029] like Figure 1 As shown, the slow flow box 6 is a hollow structure, which is arranged at the upper end of the flocculation box 5 and is connected to the flocculation box 5. Exemplarily, the slow flow box 6 includes a second baffle 61 and an observation window. The second baffle 61 is arranged at the bottom of the inner side of the slow flow box 6. The second baffle 61 separates the flow channel in the slow flow box 6 into an inverted U shape, increases the algae water stroke, improves the algae water flocculation effect, and prevents the liquid level in the separation box 1 from rising too fast, affecting the operation of the equipment. The observation window is opened on the side of the slow flow box 6 to facilitate the observation of the flocculation of the algae water.
[0030] like Figure 1 As shown, the separation box 1 is a hollow structure, which is arranged at the upper end of the flocculation box 5, and includes a drum 2, a first water outlet 11, a drive assembly and a collection tank 4. The drum 2 is a cylinder, and the cylinder surface is a mesh body. The drum 2 is rotatably connected to the separation box 1 and has an opening, which is connected to the first surface of the slow flow box 6, and the opening is higher than the bottom of the slow flow box 6. The first water outlet 11 is arranged on the first surface of the separation box 1. The drive assembly is arranged on the first surface of the separation box 1, and the output end is transmission-connected to the first surface of the drum 2. The separation box 1 includes a collection tank 4, and the collection tank 4 passes through the opening, and the part of the collection tank 4 located in the drum 2 has an upward opening.
[0031] Exemplarily, the drum 2 is horizontally arranged in the separation box 1. The mesh number of the drum 2 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 drum 2 and a clean water area between the drum 2 and the separation box 1. The algae water enters the opening of the drum 2, and the algae water passes through the cylinder surface under the action of gravity. A small amount of algae is retained by the cylinder surface, and the clean water enters the clean water area and is discharged from the first water outlet 11. The separation box 1 includes a partition plate 12 and a rolling element 13. The partition plate 12 is arranged on the second surface of the separation box 1, and a hole is opened in the middle of the partition plate 12. The outer side of the rolling element 13 is fixedly connected in the hole, and the inner side of the rolling element 13 is rotatably connected to the second surface of the drum 2. The rolling element 13 adopts a bearing structure. The driving assembly includes a motor 32 and a reducer 31. The reducer 31 is fixed to the second surface of the separation box 1, and the first end of the reducer 31 is transmission-connected to the output end of the motor 32, and the second end of the reducer 31 is transmission-connected to the filter cartridge.
[0032] Figure 3Schematic diagram of the structure of the separation box in the algae-water separation system of the utility model. Figure 1 and Figure 3 As shown, exemplarily, the collecting tank 4 includes a tank body 41 and a first slag discharge port 42. The tank body 41 is located corresponding to the inner side of the drum 2 and has an upward opening. The first slag discharge port 42 is connected to the tank body 41 through the opening, and the first slag discharge port 42 is fixed in the slow flow box 6 and passes through the slow flow box 6. Preferably, the cross-section of the tank body 41 is arc-shaped, and the collecting tank 4 is inclined upward relative to the horizontal plane 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.
[0033] like Figure 1 and Figure 3 As shown, further, the drum 2 includes a filter plate 21, and the filter plate 21 is a mesh body, which has several meshes and is arranged in a ring on the inner wall of the drum 2. Exemplarily, the filter plate 21 does not interfere with the surface of the collecting tank 4 when rotating, and the mesh number of the filter plate 21 is selected to be 200-350 meshes, which can achieve water permeability while retaining the algae. When the filter plate 21 leaves the surface of the algae water area, the algae suspended in the algae water are retained and fished out by the filter plate 21, and the clean water returns to the algae water area. Preferably, the filter plate 21 includes a first part 211 and a second part 212. The first part 211 is connected to the inner wall of the drum 2, and the second part 212 is connected to the first part 211 at an angle toward the rotation direction of the drum 2. The inclined second part 212 prevents the algae from flowing back to the algae water area from the first part 211 too quickly with the algae water, thereby improving the efficiency of the filter plate 21 in collecting algae residues. Specifically, the angle a between the first portion 211 and the inner wall of the drum 2 is 30° to 160°, and the angle b between the second portion 212 and the first portion 211 is 120° to 160°.
[0034] like Figure 1 and Figure 3 As shown, further, the separation box 1 further includes a nozzle 14, a pump body and a return pipe 15. The nozzle 14 is arranged in the separation box 1, and sprays toward the cylinder surface of the outer side of the drum 2 below the collecting tank 4. The pump body is arranged at the lower end of the interior of the separation box 1, and the return pipe 15 connects the pump body and the nozzle 14. Specifically, the pump body draws the clean water in the clean water area into the return pipe 15, and the nozzle 14 sprays the clean water to flush the algae remaining on the cylinder surface of the drum 2 into the algae water area. At the same time, when the filter plate 21 passes through the injection path, the algae remaining on the filter plate 21 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 21 and the filter cylinder.

Figure 5 It is a schematic diagram of the structure of the air flotation device in the algae-water separation system of the utility model. Figure 6 It is a schematic structural diagram of the dehydration device in the algae-water separation system of the utility model.
[0036] like Figures 4 to 6 As shown, further, the algae-water separation system also includes a regulating tank 8, a dehydration device 9 and an air flotation device 10. The regulating tank 8 has a third water inlet 81, a fifth water inlet 83 and a third water outlet 82, and the third water inlet 81 is connected to the first slag outlet 41. The dehydration device 9 has a fourth water inlet 91, a fourth water outlet 92 and a first algae outlet 93, the fourth water inlet 91 is connected to the third water outlet 82, and the fourth water outlet 92 is connected to the second water inlet 101. The air flotation device 10 has a second water inlet 101, a second water outlet 103 and a second slag outlet 102, the second water outlet 103 discharges clean water, and the second slag outlet 102 is connected to the fifth water inlet 83. The regulating tank 8 receives the algae residue discharged from the first residue discharge port 41, and the algae residue enters the fourth water inlet 91 of the dehydration device 9 through the third water outlet 82. The dehydration device 9 separates the algae residue from water again, and the algae residue is discharged through the first algae outlet 93. The tail water enters the air flotation device 10 through the fourth water outlet 92 and the second water inlet 101. The algae residue removed by air flotation by the air flotation device 10 is returned to the regulating tank 8 for dehydration. The dehydration device 9 is preferably a spiral dehydrator, which separates the algae and clean water by screw extrusion. The air flotation device 10 is preferably a vortex air flotation device.
[0037] like Figure 4 As shown, further, the algae-water separation system also includes a dosing device 7, which is connected to the flocculation tank 5 and the dehydration device 9 through a dosing pipeline 71. The dosing device 7 includes a stirring tank and a metering pump, and the metering pump pumps the flocculant in the stirring tank to the flocculation tank 5 and the dehydration device 9 through the dosing pipeline 71.
[0038] When this embodiment is working:
[0039] The algae water enters the flocculation box 5 through the first water inlet 51, flows in the flocculation box 5 and mixes with the flocculant, then enters the slow flow box 6 and rises. After rising, the algae water enters the algae water area in the drum 2. During the rotation of the filter plate 21, the algae bodies suspended in the algae water are retained and fished out by the filter plate 21, and the clean water returns to the algae water area. When the filter plate 21 rotates to the height of the filter cartridge, a large amount of algae bodies hanging on the filter plate 21 and a small amount of algae bodies on the inner surface of the filter cartridge fall into the collecting tank 4 under the action of gravity and are discharged. The regulating tank 8 receives the algae residue discharged from the first residue discharge port 41, and the algae residue enters the fourth water inlet 91 of the dehydration device 9 through the third water outlet 82. The dehydration device 9 separates the algae residue from the water again through screw extrusion, and the algae residue is discharged through the first algae outlet 93. The tail water enters the air flotation device 10 through the fourth water outlet 92 and the second water inlet 101. The air flotation device 10 removes a small amount of algae residue in the tail water by air flotation.
[0040] In this embodiment, the algae water with added flocculants is diverted by passing through the flocculation box 5 and the slow flow box 6 in sequence, thereby increasing the flocculation reaction time and improving the flocculation effect of the algae. At the same time, the opening of the drum 2 is higher than the bottom of the slow flow box 6, which increases the climbing time of the algae water and avoids the liquid level in the separation box 1 from rising too quickly, thereby ensuring the normal operation of the equipment.
[0041] 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.
