[0002] Industrial circulating water contains molecules that pollute the environment, so it needs to be sterilized, algae-killed and descaled before being discharged. The existing technology uses electromagnetic fields to treat industrial and domestic water, which is a kind of physical water treatment. Its principle is to make water pass through an electromagnetic field, thereby breaking the bonds of water in a large complex state, and dissociating the water into highly active single molecules or water in a small complex state, thereby changing the physical structure and properties of the water, increasing the dipole moment of water molecules, and changing the deposition state of sedimentary substances in the water and the physical properties of various ions, thereby effectively achieving the purpose of scale prevention, descaling, sterilization, algae removal, rust prevention and corrosion prevention, and activating and clearing the water quality.

[0031] like Figure 1-Figure 4 As shown, a circulating water sterilization and algae removal device for a power plant comprises a treatment box 1, wherein a positive plate 101 and a negative plate 102 are penetrated and fixed on both sides of the treatment box 1, a frequency sweeping signal generator 103 is arranged on the right side of the treatment box 1, the positive plate 101 and the negative plate 102 are electrically connected to the frequency sweeping signal generator 103, a water inlet pipe is connected and fixed to the top surface of the treatment box 1, a filter assembly is arranged below the treatment box 1, the filter assembly comprises a filter box 2 arranged below the treatment box 1, the bottom end of the treatment box 1 is penetrated and fixed to the top surface of the filter box 2, a fixing rod 201 is arranged on the front and back sides of the interior of the filter box 2, a filter screen 202 is fixed between the two fixing rods 201, two isolation plates 203 are fixed inside the filter box 2, the two isolation plates 203 divide the interior of the filter box 2 into three cavities, the first cavity, the second cavity and the third cavity are arranged from the right side to the left side of the interior of the filter box 2, and the bottom end of the treatment box 1 corresponds to the position of the second cavity.

[0032] like Figure 3-Figure 7 As shown, in this embodiment, a limiting cylinder 204 is fixed on the inner bottom surface of the filter box 2, and the two limiting cylinders 204 are respectively located inside the first cavity and the third cavity. A support frame 205 is slidably inserted inside the limiting cylinder 204, and three first springs 206 are fixed between the top surface of the support frame 205 and the inner top surface of the limiting cylinder 204. The front and rear sides of the support frame 205 are rotatably connected with connecting rollers 207, and the two sides of the two fixed rods 201 away from each other are fixed with sliding frames 208. The left and right sides of the sliding frame 208 are both inclined structures, and the connecting roller 207 is located between the sliding frame 208 and the fixed rod 201. A cleaning brush 214 is fixed on the bottom surface of the sliding frame 208. By inputting circulating water from the water inlet pipe into the processing box 1, and then starting the sweep signal generator 103 to discharge the positive plate 101 and the negative plate 102 and dissociate the water, and then the water containing sediment after the dissociation is introduced into the filter The second cavity inside the box 2, and the circulating water is filtered through the part of the filter screen 202 located inside the second cavity. After filtering a part of the circulating water, the filter screen 202 can be driven to move horizontally, so that the filter screen 202 covered with sediment is moved to the first cavity or the third cavity. At this time, the connecting roller 207 cooperates with the sliding frame 208 and the fixed rod 201 to lift the support frame 205 and the cleaning brush 214, and avoid the filter screen 202 to prevent the cleaning brush 214 from scraping the sediment of the filter screen 202 into the second cavity. Subsequently, when the filter screen 202 in the second cavity is covered with sediment, the filter screen 202 inside the first cavity or the third cavity returns to the second cavity, and at this time the support frame 205 will not rise in conjunction, and the cleaning brush 214 is close to the surface of the filter screen 202 and scrapes the sediment from the filter screen 202, thereby realizing automatic cleaning of the filter screen 202.

One side of the triangular block 212 is at the same height as the inclined surface of the sliding frame 208, and the inclinations of the two are equal. When the filter screen 202 is moved to the first cavity or the third cavity, the connecting roller 207 in the moving direction of the filter screen 202 rolls relative to the inclined surface of the sliding frame 208 and the inclined surface of the triangular block 212 and moves to the top surface of the sliding frame 208, so that the support frame 205 slides upward inside the limiting cylinder 204 and the first spring 206 is compressed. At this time, the cleaning brush 214 moves away from the filter screen 202 with the support frame 205, avoids the filter screen 202, and prevents the cleaning brush 214 from scraping the sediment of the filter screen 202 into the second cavity. When the connecting roller 207 moves to the first drop hole 209, the cleaning brush 214 originally located in the second cavity When the filter screen 202 inside is completely moved to the first cavity or the third cavity, the first spring 206 rebounds quickly and presses the support frame 205 and the connecting roller 207 to fall into the first drop hole 209. At this time, the cleaning brush 214 is again attached to the top surface of the filter screen 202 with the support frame 205. When the filter screen 202 inside the first cavity or the third cavity moves to the second cavity again, the connecting roller 207 in the opposite direction of the movement of the filter screen 202, that is, the connecting roller 207 falling into the first drop hole 209 mentioned above, moves relatively between the fixed rod 201 and the sliding frame 208. At this time, the support frame 205 does not rise, and the cleaning brush 214 It is closely attached to the surface of the filter screen 202, and as the filter screen 202 moves, the sediment is scraped off the filter screen 202 and discharged into the first cavity and the third cavity. Then, when the connecting roller 207 moves to the triangular block 212, the connecting roller 207 is squeezed by the internal inclined surfaces of the triangular block 212 and the sliding frame 208, so that the triangular block 212 is pressed into the inside of the rebound groove 211 and the second spring 213 is compressed. Then, the connecting roller 207 returns to the outer wall inclined surface of the sliding frame 208. At this time, the second spring 213 rebounds quickly to drive the triangular block 212 to reset, thereby realizing the reset of the connecting roller 207.

Through the internal sliding arrangement of the support bars 5 and the support grooves 501, the fixed rods 201 can be supported.

[0037] like Figure 4-Figure 7 As shown, in this embodiment, a waterproof arc plate 6 is fixed to the bottom surface of the two fixed rods 201, and the electric push rod 3 is located inside the waterproof arc plate 6. The waterproof arc plate 6 can protect the electric push rod 3 to prevent the circulating water from being contaminated by the electric push rod 3 when filtering the circulating water, thereby preventing the electric push rod 3 from being damaged.

[0038] like Figure 4-Figure 7 As shown, in this embodiment, avoidance holes 7 are provided on the top surfaces of the two isolation plates 203 near the front and rear sides, and the avoidance holes 7 can avoid the waterproof arc plate 6 to prevent the movement of the filter screen 202 from being hindered.

[0040] like Figure 4-Figure 7As shown, in this embodiment, a driving motor 9 is fixed to the top surface of the processing box 1, and the output shaft of the driving motor 9 extends through the interior of the processing box 1. A glass-lined agitator 901 is fixed to the output shaft end of the driving motor 9. When the positive plate 101 and the negative plate 102 discharge and decompose the water, the driving motor 9 is started to drive the glass-lined agitator 901 to stir the circulating water, thereby increasing the decomposition effect of the circulating water.

[0041] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: in use, circulating water is input into the processing box 1 from the water inlet pipe, and then the sweep signal generator 103 is started to discharge the positive plate 101 and the negative plate 102 and dissociate the water, and then the drive motor 9 is started to drive the glass-lined agitator 901 to stir the circulating water, and then the water valve at the bottom of the processing box 1 is opened so that the circulating water is discharged into the second cavity of the filter box 2, and the circulating water is filtered through the partial filter screen 202 located in the second cavity. After filtering a part of the circulating water, the filter screen 202 is covered with sediment. Starting the electric push rod 3 can drive the filter screen 202 to move left and right inside the filter box 2. When the filter screen 202 is covered with sediment, the filter screen 202 is filtered. When the filter screen 202 is moved to the first cavity or the third cavity, the connecting roller 207 in the moving direction of the filter screen 202 rolls relative to the inclined surface of the sliding frame 208 and the inclined surface of the triangular block 212 and moves to the top surface of the sliding frame 208, so that the support frame 205 slides upward inside the limiting cylinder 204 and the first spring 206 is compressed. At this time, the cleaning brush 214 moves away from the filter screen 202 with the support frame 205, and avoids the filter screen 202 to prevent the cleaning brush 214 from scraping the sediment of the filter screen 202 into the second cavity. When the connecting roller 207 moves to the first drop hole 209, the filter screen 202 originally located in the second cavity is completely moved to the first cavity or the third cavity. At this time, the first spring 206 quickly rebounds and presses the support frame 205 and the connecting roller 207 to fall into the first drop hole 209. At this time, the cleaning brush 214 is in contact with the top surface of the filter 202 again with the support frame 205. When the filter 202 inside the first cavity or the third cavity moves to the second cavity again, the connecting roller 207 in the opposite direction of the movement of the filter 202, that is, the connecting roller 207 falling into the first drop hole 209 mentioned above, moves relatively between the fixed rod 201 and the sliding frame 208. At this time, the support frame 205 does not rise, and the cleaning brush 214 is in close contact with the surface of the filter 202, and with the movement of the filter 202, the sediment is scraped off the filter 202 and discharged into the first cavity and the third cavity. Then the connecting roller 207 moves When it reaches the triangular block 212, the connecting roller 207 is squeezed by the internal inclined surfaces of the triangular block 212 and the sliding frame 208, so that the triangular block 212 is pressed into the inside of the rebound groove 211 and the second spring 213 is compressed. Then the connecting roller 207 returns to the outer wall inclined surface of the sliding frame 208. At this time, the second spring 213 rebounds quickly to drive the triangular block 212 to reset, thereby realizing the reset of the connecting roller 207. The first limiting rod 4 can limit the sliding frame 208 and support the first spring 206. The second limiting rod 401 can limit the triangular block 212 and support the second spring 213.
