[0003] Currently, in the process of filtering water sources, in order to improve the filtering efficiency of the filtering station, multiple filter elements are arranged inside the filtering equipment.

[0023] In this embodiment, in the process of filtering large-flow tap water, in order to further improve the filtering efficiency, firstly, the external water pipe and the connecting pipe 202 are fixedly connected through a seal, and then the external pump body is started, so that the water source to be purified can be transported to the inside of the filter tank 201 through the connecting pipe 202, and the water source enters the inside of the multiple filter elements 311 through multiple positioning rings 302 respectively, wherein the connection between the multiple positioning rings 302 and the circular plate 301 is provided with a sealing ring, and the sealing ring is made of a rubber material with strong waterproof performance, which will not cause particle impurities to pass through the connection between the positioning ring 302 and the circular plate 301. The water source enters the upper part of the circular plate 301. In addition, the connection between the circular plate 301 and the filter tank 201 is also waterproofed, and the treatment method is consistent with the above. After the water source enters the interior of the multiple filter elements 311 through the positioning ring 302, the impurities in the water are retained in the interior of the filter element 311. The purified water source enters the outside of the filter element 311 through the filter holes in the multiple filter elements 311, and then the second water pump 205 can be started to drive the water inlet pipe 206 to extract the purified water source into the interior of the filter tank 201. The water source enters the interior of the collection tank 208 through the water outlet pipe 207, thereby realizing the purification and collection of the water source. The pressure in the filter tank 201 is detected by the pressure sensor 11, wherein the working principle of the pressure sensor 11 is to convert the pressure signal applied by the outside into a readable electrical signal output. When the metal wire is subjected to external force, its length and cross-sectional area will change, resulting in a change in resistance value. The change in resistance is converted into a change in voltage or current through the measuring circuit, thereby obtaining an electrical signal corresponding to the pressure. When the pressure sensor 11 detects that the pressure is too high, it means that there are too many impurities inside the filter element 311 and the filter element 311 has been blocked. At this time, the first solenoid valve 203 and the second water pump 205 are closed by the controller 5, and the two electromagnets 310 are electrically connected to the external power supply to generate a magnetic field, thereby adsorbing the two lifting blocks 304, wherein the lifting blocks 304 are made of metal iron material, so that the two lifting blocks 304 are moved downward and inserted into the two corresponding mounting grooves 309. At the same time, the movement of the two lifting blocks 304 also causes the two springs 305 to stretch. When the two lifting blocks 304 are inserted into the two mounting grooves 309, wherein, as Figure 5As shown, the cross sections of the two lifting blocks 304 match the internal cross sections of the two card slots 303 respectively, and are both cross-shaped. The purpose is to facilitate the downward movement of the lifting blocks 304 while preventing them from moving out of the card slots 303. The stepper motor 306 is started to drive the rotating ring 312 to rotate, thereby driving the square slot 313 to rotate. When the infrared sensor 331 detects that the square slot 313 is directly opposite to the positioning frame 318, the two electric push rods 315 located at the top are started at the same time to shorten them, driving the two lifting plates 316 to move downward, thereby driving the hollow tube 317 to move downward, and then driving the threaded tube 320 to move downward, so that the multiple telescopic tubes 322 are extended, and then the corrugated tube 323 is extended. During the downward movement of the hollow tube 317, the positioning frame 318 is also driven downward, and then the positioning frame 328 is embedded in the interior of the square slot 313, so that the nozzle 319 moves to the interior of the rotating ring 312. Figure 7As shown, the outer surface of the nozzle 319 is provided with a plurality of nozzle holes, the purpose of which is to further improve the efficiency of the spraying, and then the stepper motor 306 is started to drive the rotating shaft 307 to rotate, thereby driving the rotating block 308 to rotate, thereby driving the two lifting blocks 304 embedded therein to rotate, and the rotation of the two lifting blocks 304 drives the matching positioning ring 302 to rotate, thereby driving the filter element 311 connected thereto to rotate, thereby driving the rotating ring 312 at the top thereof to rotate, thereby driving the positioning frame 318 to rotate, and the rotation of the positioning frame 318 causes the threaded tube 320 connected thereto to move downward under the action of the rotating force, thereby driving the nozzle 319 to move, and when the threaded tube 320 passes through the rotating shaft 307, the nozzle 319 is moved. After the ring 312 enters the interior of the filter element 311, the first water pump 318 can be started to drive the liquid inlet pipe 329 to draw pure water into the water purification tank 327. The water source enters the interior of the bellows 323 through the liquid outlet pipe 330, and finally enters the interior of the threaded pipe 320, and then enters the interior of the nozzle 319. The nozzle 319 rotates and moves downward, so that the substances retained on the inner wall of the filter element 311 are separated from the interior of the filter element 311 under the impact of the water source. At the same time, the rotation of the filter element 311 also separates the dirt retained on the inner wall of the filter element 311 from the inner wall of the filter element 311 under the action of centrifugal force. The separated dirt flows downward with the water source and enters the bottom of the circular plate 301, and then the nozzle 319 can be opened. The second solenoid valve 10 is opened, so that the cleaned sewage enters the waste liquid tank 8 along the drain pipe 9 for collection, thereby realizing the cleaning of the filter element 311. By cleaning each filter element 311 individually, the problem of incomplete cleaning of the filter element 311 that is easily caused by unified backwashing inside the filtering equipment in the prior art is solved. When one of the filter elements 311 is cleaned, the first water pump 328 is turned off, and the stepper motor 306 is started again to drive the rotating shaft 307 to rotate in the opposite direction. The stepper motor 306 can drive the rotating shaft 307 to switch between clockwise and counterclockwise rotation. This is an existing mature technology and will not be introduced in detail here. The reverse rotation of the rotating shaft 307 drives the filter element 311 to rotate in the opposite direction. The two electromagnets 310 are disconnected from the external power supply, so that the two lifting blocks 304 are respectively shortened under the elastic action of the two springs 305 connected thereto, thereby driving the two lifting blocks 304 to move out of the two mounting grooves 309 respectively, and the servo motor 601 is started to drive the connecting shaft 602 to rotate, thereby driving the first bevel gear 603 to rotate, thereby driving the second bevel gear 604 to rotate, and causing the rotating rod 605 to rotate, wherein, as shown in FIG. Figure 8As shown, a sealing ring is provided at the connection between the rotating rod 605 and the filter tank 201, the purpose of which is to prevent water from leaking along the connection between the rotating rod 605 and the filter tank 201. The rotating rod 605 drives the circular plate 301 to rotate, thereby driving the multiple filter elements 311 embedded therein to rotate, wherein the rotation speed of the circular plate 301 is controlled in advance by the controller 5, when the circular plate 301 drives the next filter element 311 to be cleaned to rotate to the position of the two mounting grooves 309, the two electromagnets 310 are electrically connected to the external power supply again, and when the two lifting blocks 304 rotate to the positions of the two mounting grooves 309 respectively, they can be adsorbed again, and then the stepping motor 306 and the first water pump 328 are started again, and the filter element 311 can be cleaned again, and the orderly rotation of the circular plate 301 facilitates the working efficiency of the automatic cleaning filter equipment of the large flow automatic backwashing equipment.

[0026] The use method and working principle of the device: In the process of intelligent filtration of large-flow tap water, in order to further improve the automatic filtration efficiency, first, the external water pipe and the connecting pipe 202 are fixedly connected through a seal, and then the external pump body is started, so that the water source to be purified can be transported to the inside of the filter tank 201 through the connecting pipe 202, and the water source enters the inside of the multiple filter elements 311 through the multiple positioning rings 302 respectively. After the water source enters the inside of the multiple filter elements 311 through the positioning rings 302 respectively, the impurities in the water are retained in the inside of the filter element 311, and the purified water source enters the outside of the filter element 311 through the filter holes in the multiple filter elements 311, and then the second water pump 205 can be started to drive the water inlet pipe 206 to the filter The purified water source is extracted from the inside of the tank 201, and the water source enters the inside of the collection tank 208 through the outlet pipe 207. When the pressure sensor 11 detects that the pressure of the filter tank 201 is too high, the first solenoid valve 203 and the second water pump 205 are closed through the controller 5, and the two electromagnets 310 are electrically connected to the external power supply to generate a magnetic field, thereby adsorbing the two lifting blocks 304, wherein the lifting blocks 304 are made of metal iron material, so that the two lifting blocks 304 are moved downward and inserted into the two corresponding installation grooves 309. At the same time, the movement of the two lifting blocks 304 also makes the two springs 305 extend. When the two lifting blocks 304 are inserted into the two installation grooves 309, wherein, as shown in FIG. Figure 5As shown, the cross sections of the two lifting blocks 304 match the internal cross sections of the two slots 303 respectively, and are both cross-shaped, the purpose of which is to facilitate the lifting blocks 304 to move downward while preventing them from moving out of the slots 303. The stepper motor 306 is started to drive the rotating ring 312 to rotate, thereby driving the square slot 313 to rotate. When the infrared sensor 331 detects that the square slot 313 is facing the positioning frame 318, the two electric push rods 315 at the top are started at the same time to shorten them, drive the two lifting plates 316 to move downward, and then drive the hollow tube 317 to move downward, and then drive the threaded tube 320 to move downward, so that the multiple telescopic tubes 322 are extended, and then the corrugated tube 323 is extended, and the hollow tube 317 moves downward. During the movement, the positioning frame 318 is also driven to move downward, and the positioning frame 328 is embedded in the inside of the square groove 313, so that the nozzle 319 is moved to the inside of the rotating ring 312, and then the stepping motor 306 is started to drive the rotating shaft 307 to rotate, and then the rotating block 308 is driven to rotate, thereby driving the two lifting blocks 304 embedded in it to rotate, and the rotation of the two lifting blocks 304 drives the matching positioning ring 302 to rotate, and then drives the filter element 311 connected to it to rotate, and then drives the rotating ring 312 at the top to rotate, thereby driving the positioning frame 318 to rotate, and the rotation of the positioning frame 318 causes the threaded pipe 320 with its internal thread connection to move downward under the action of the rotational force, thereby driving the nozzle 319 to move. When the threaded tube 320 passes through the rotating ring 312 and enters the interior of the filter element 311, the first water pump 318 can be started to drive the liquid inlet pipe 329 to extract pure water into the water purification tank 327. The water source enters the interior of the bellows 323 through the liquid outlet pipe 330, and finally enters the interior of the threaded tube 320, and then enters the interior of the nozzle 319. The nozzle 319 rotates and moves downward, so that the substances retained on the inner wall of the filter element 311 are separated from the interior of the filter element 311 under the impact of the water source. At the same time, the rotation of the filter element 311 also separates the dirt retained on the inner wall of the filter element 311 from the inner wall of the filter element 311 under the action of centrifugal force. The separated dirt flows downward with the water source and enters the bottom of the circular plate 301, and then the filter element 311 can be opened. The second solenoid valve 10 allows the cleaned sewage to enter the waste liquid tank 8 along the drain pipe 9 for collection. When one of the filter elements 311 is cleaned, the first water pump 328 is turned off, and the stepper motor 306 is started again to drive the shaft 307 to rotate in the opposite direction. The reverse rotation of the shaft 307 drives the filter element 311 to rotate in the opposite direction, thereby driving the swivel 312 to rotate in the opposite direction, and then the threaded tube 320 drives the nozzle 319 to move upward. When the nozzle 319 is completely moved to the outside of the swivel 312, the nozzle 319 is completely moved out of the filter element 311, and then the two electromagnets 310 are disconnected from the external power supply, so that the two lifting blocks 304 are shortened respectively under the elastic action of the two springs 305 connected thereto.Then, the two lifting blocks 304 are driven to move out from the inside of the two installation grooves 309 respectively, and the servo motor 601 is started to drive the connecting shaft 602 to rotate, and then the first bevel gear 603 is driven to rotate, thereby driving the second bevel gear 604 to rotate, so that the rotating rod 605 rotates, and the rotating rod 605 drives the circular plate 301 to rotate, thereby driving the multiple filter elements 311 embedded therein to rotate. When the circular plate 301 drives the next filter element 311 to be cleaned to rotate to the position of the two installation grooves 309, the two electromagnets 310 are electrically connected to the external power supply again. When the two lifting blocks 304 are rotated to the positions of the two installation grooves 309 respectively, they can be adsorbed again, and then the stepping motor 306 and the first water pump 328 are started again, and the filter element 311 can be cleaned again. Since the filter element 311 is filtering the water source, During the process, the outer wall of the filter element 311 will also retain the mud and sand in the water. In order to achieve comprehensive cleaning of the filter element 311, during the process of flushing the interior of multiple filter elements 311, when the first water pump 328 drives the liquid inlet pipe 329 to draw water into the clean water tank 327, while the water flows outward through the liquid outlet pipe 330, a part of the water will enter the interior of the spray plate 702 along the diverter pipe 701, and be sprayed outward through the spray plate 702, so that the interior of the filter element 311 can also be washed away during the rotation cleaning process. In addition, since the small amount of dirt retained on the outside is filtered out by the filter element 311 and its volume is smaller than the filter hole of the filter element 311, it will enter the interior of the filter element 311 and then enter the interior of the filter tank 201, and then enter the interior of the waste liquid tank 8.
