[0002] Purified water refers to H2O without impurities. It is pure, clean, and does not contain impurities or bacteria, such as organic pollutants, inorganic salts, any additives, and various impurities.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In the process of preparing pure water, the raw water is first fed into the water treatment tank from the water inlet, and then passes through the filter barrel in turn, and is initially filtered by the first filter screen. The water that has undergone preliminary filtration then enters the reverse osmosis filter tank at the bottom of the water treatment tank. The untreated water flows into the water inlet chamber through the guide plate on the top of the reverse osmosis filter tank, and then passes through the reverse osmosis membrane into the water outlet chamber. Specifically, the water inlet chamber is an empty chamber, and the water outlet chamber is filled with solution. The salt in the water is then removed by reverse osmosis treatment. Finally, the water treated by the reverse osmosis equipment enters the EDI equipment through the connecting pipe. I equipment integrates electrodialysis technology and ion exchange technology. Through the selective permeation of anions and cations by anion and cation exchange membranes and the exchange of ions by ion exchange resins, directional ion migration is achieved under the action of a DC electric field, thereby completing the deep desalination of water. In addition, the use of EDI equipment and reverse osmosis devices organically combines traditional electrodialysis technology and ion exchange technology to continuously produce high-quality pure water without the use of acids and alkalis, completely getting rid of the problems of acid and alkali consumption and chemical waste liquid pollution, thereby achieving true clean production and reducing environmental pollution caused by the pure water preparation process.

[0018] 2. When the first filter is clogged with impurities, the fixed plate slides downward on the top of the water treatment tank, driving the adsorption cylinder arranged on the platform plate to move downward, thereby adjusting the adsorption cylinder to a suitable height, and then rotating the fan blades on the adsorption cylinder to generate an air pressure difference between the inside and outside of the adsorption cylinder, and adsorbing the impurities on the first filter into the adsorption cylinder. At the same time, the second filter will filter large impurities to prevent them from entering the adsorption cylinder and clogging the fan blades in the adsorption cylinder. Subsequently, the sliding block is driven to slide on the platform plate, so that the adsorption cylinder can move linearly on the platform plate, and cooperate with the platform plate to rotate on the fixed plate, thereby The first filter screen is cleaned at various locations, thereby improving the cleaning effect of the first filter screen and eliminating the need for frequent replacement of the first filter screen. This solves the problem of the pure water preparation device being unable to guarantee the quality of the pure water produced over a long period of time, thereby improving the long-term filtering effect of the preparation device on raw water and the quality of the pure water produced over a long period of time. In addition, the rotation of the shaft on the sliding block drives the adsorption tube at the end of the adsorption cylinder to rotate, thereby enhancing the adsorption effect of impurities. At the same time, the curved plate in the adsorption tube can expand the adsorption range and, through collision between the curved plate and larger impurities, break up larger impurities, preventing large impurities from entering the adsorption cylinder and causing blockage.

[0019] 3. When the first filter needs to be cleaned, the movable rack is driven to slide back and forth on the platform plate by the first electric telescopic rod. Since the gear provided at the end of the rotating shaft is engaged with the movable rack, the rotating shaft is driven to rotate on the sliding block, and the adsorption tube located at the end of the adsorption cylinder is driven to rotate, thereby enhancing the effect of adsorbing impurities; in addition, when the gear rotates on the sliding block, the gear is simultaneously engaged with the fixed rack, thereby driving the sliding block to slide on the platform plate, cooperating with the platform plate to rotate on the fixed plate, thereby cleaning various parts of the first filter screen, improving the cleaning effect of the first filter screen, and at the same time, no additional power device is required to drive the rotating shaft to rotate on the sliding block, thereby reducing the cost required for manufacturing the power device and the space required for installation;

[0020] 4. Through the cooperation among the first motor, the rocker arm, the connecting rod and the movable rack, the movable rack is driven to slide back and forth on the platform plate. Since the gear provided at the end of the rotating shaft is engaged with the movable rack, the rotating shaft is driven to rotate on the sliding block, and the adsorption tube located at the end of the adsorption cylinder is driven to rotate, thereby enhancing the effect of adsorbing impurities. At the same time, there is no need to frequently change the reverse direction of the power device, thereby extending the service life of the power device. In addition, when the gear rotates on the sliding block, the gear and the fixed rack are cooperated to drive the sliding block to slide on the platform plate, and the platform plate rotates on the fixed plate, thereby cleaning various parts of the first filter screen, improving the cleaning effect of the first filter screen, and at the same time, there is no need to set up an additional power device to drive the rotating shaft to rotate on the sliding block, thereby reducing the cost required for manufacturing the power device and the space required for installation.

[0021] When it is necessary to change the adsorption range of the adsorption cylinder, the restriction on the relative sliding between the rocker arm and the slide bar is released through the cooperation among the first cylinder, the push block, the rocker arm, the limit block and the slot. At the same time, the second cylinder is extended and retracted to drive the slide bar to slide relative to the rocker arm, so that the overall length of the rocker arm and the slide bar changes, thereby changing the activity range of the adsorption cylinder, so that the adsorption cylinder can usually perform local cleaning of the area with more impurities, and cooperate with the full-range cleaning of the adsorption cylinder periodically, thereby further improving the efficiency of cleaning the first filter screen and improving the cleaning effect of the area with more impurities; finally, the push block is driven to reset by the first cylinder, so that the limit block enters the corresponding slot, limiting the movement of the slide bar relative to the rocker arm, thereby ensuring the stability of the overall structure and improving the effect of cleaning the first filter screen;

[0022] 5. When the reverse osmosis membrane needs to be replaced, the fixing rod to the reverse osmosis membrane is released through the cooperation among the screw, the pressure block, the fixing rod, the limiting rod, the reverse osmosis filter tank, the first cone surface, the limiting groove and the second spring. At the same time, the rebound force generated by the compression of the first spring drives the reverse osmosis membrane to pop out, which is convenient for subsequent replacement of the reverse osmosis membrane and prevents the reverse osmosis membrane from being unable to work due to scale adhering to the surface of the reverse osmosis membrane after long-term use, thereby improving the stability of the overall structure of the reverse osmosis equipment and improving the effect of preparing pure water;

[0023] When the reverse osmosis membrane needs to be fixed, the replaced reverse osmosis membrane is placed in the corresponding position of the reverse osmosis filter tank, and the movement of the reverse osmosis membrane on the reverse osmosis filter tank is restricted by the cooperation between the fixing rod, the protrusion, and the reverse osmosis membrane. Then, the movement of the limit rod toward the inside is restricted by the cooperation between the screw, T-block, the pressure block, the T-slot, the fixing rod, the second cone surface, and the wedge block. The resistance generated by the contact between the limit rod and the limit slot further restricts the movement of the reverse osmosis membrane on the reverse osmosis filter tank, thereby avoiding external force from accidentally acting on the reverse osmosis membrane and releasing the fixing effect of the fixing rod on the reverse osmosis membrane, which affects the subsequent effect of the reverse osmosis membrane in removing salt from water, thereby improving the effect of preparing pure water.

[0052] Example 1

[0053] The present invention provides an electric regeneration pure water preparation device, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, in the process of preparing pure water, the raw water is first introduced into the water treatment tank 2 from the water inlet 3, so that the raw water passes through the filter barrel 4 in turn, and is initially filtered by the first filter screen 5. The water after the preliminary filtration then enters the reverse osmosis filter tank 6 located at the bottom of the water treatment tank 2, and the untreated water flows into the water inlet chamber 8 through the guide plate 10 provided on the top of the reverse osmosis filter tank 6, and then passes through the reverse osmosis membrane 7 into the water outlet chamber 9. Specifically, the water inlet chamber 8 is an empty chamber, and the water outlet chamber 9 is filled with a solution, and then the salt in the water is removed by reverse osmosis treatment. Finally, the water treated by the reverse osmosis equipment enters the EDI device through the connecting pipe 12. In preparation 11, the EDI device 11 integrates electrodialysis technology and ion exchange technology. Through the selective permeation of anions and cations by anion and cation exchange membranes and the exchange of ions by ion exchange resins, directional migration of ions is achieved under the action of a DC electric field, thereby completing the deep desalination of water. In addition, the use of the EDI device 11 and a reverse osmosis device organically combines traditional electrodialysis technology and ion exchange technology to continuously produce high-quality pure water without the use of acids and alkalis, completely getting rid of the problems of acid and alkali consumption and chemical waste liquid pollution, thereby achieving true clean production and reducing environmental pollution caused by the pure water preparation process.

[0054] When the first filter screen 5 is clogged with impurities, the fixed plate 13 slides downward on the top of the water treatment tank 2, driving the adsorption cylinder 19 set on the platform plate 15 to move downward, thereby adjusting the adsorption cylinder 19 to a suitable height, and then rotating the fan blade 20 on the adsorption cylinder 19, so that an air pressure difference is generated between the inside and outside of the adsorption cylinder 19, and the impurities on the first filter screen 5 are adsorbed into the adsorption cylinder 19, and at the same time, the second filter screen 21 will filter large impurities to prevent them from entering the adsorption cylinder 19 and clogging the fan blade 20 in the adsorption cylinder 19, and then the sliding block 17 is driven to slide on the platform plate 15, so that the adsorption cylinder 19 can move linearly on the platform plate 15, and cooperate with the platform plate 15 to move on the fixed plate 1 3, thereby cleaning various parts of the first filter screen 5, improving the cleaning effect of the first filter screen 5, and at the same time, there is no need to frequently replace the first filter screen 5, thereby solving the problem that the pure water preparation device cannot guarantee the quality of pure water produced in the long term, improving the effect of the preparation device in filtering raw water in the long term, and improving the quality of pure water produced in the long term; in addition, the rotation of the shaft 18 on the sliding block 17 drives the adsorption tube 22 located at the end of the adsorption cylinder 19 to rotate, thereby enhancing the effect of adsorbing impurities; at the same time, the arc plate 23 in the adsorption tube 22 can expand the range of adsorption, and the arc plate 23 collides with larger impurities, thereby breaking up relatively large impurities, preventing large impurities from entering the adsorption cylinder 19 and causing blockage.

[0055] Example 2

[0056] On the basis of Example 1, Figure 3 and Figure 4 As shown, when the first filter screen 5 needs to be cleaned, the movable rack 25 is driven to slide back and forth on the platform plate 15 by the first electric telescopic rod 27. Since the gear 26 provided at the end of the rotating shaft 18 is engaged with the movable rack 25, the rotating shaft 18 is driven to rotate on the sliding block 17, and the adsorption tube 22 located at the end of the adsorption cylinder 19 is driven to rotate, thereby enhancing the effect of adsorbing impurities; in addition, when the gear 26 rotates on the sliding block 17, since the gear 26 is simultaneously engaged with the fixed rack 24, the sliding block 17 is driven to slide on the platform plate 15, and the platform plate 15 rotates on the fixed plate 13, thereby cleaning various parts of the first filter screen 5, improving the cleaning effect of the first filter screen 5, and at the same time, there is no need to set up an additional power device to drive the rotating shaft 18 to rotate on the sliding block 17, thereby reducing the cost required for manufacturing the power device and the space required for installation.

[0057] Example 3

[0058] On the basis of Example 1, Figure 6 、 Figure 7 and Figure 8As shown, the rocker arm 29 is driven to rotate by the first motor 28. Since the two ends of the connecting rod 30 are respectively connected to the movable rack 25 and the rocker arm 29 for rotation, the movable rack 25 is driven to slide back and forth on the platform plate 15. Since the gear 26 provided at the end of the rotating shaft 18 is engaged with the movable rack 25, the rotating shaft 18 is driven to rotate on the sliding block 17, and the adsorption tube 22 located at the end of the adsorption cylinder 19 is driven to rotate, thereby enhancing the effect of adsorbing impurities. At the same time, there is no need to frequently change the reverse direction of the power device, thereby extending the service life of the power device. In addition, when the gear 26 rotates on the sliding block 17, the gear 26 cooperates with the fixed rack 24 to drive the sliding block 17 to slide on the platform plate 15, and cooperates with the platform plate 15 to rotate on the fixed plate 13, thereby cleaning various parts of the first filter screen 5, improving the cleaning effect of the first filter screen 5, and at the same time, there is no need to set up an additional power device to drive the rotating shaft 18 to rotate on the sliding block 17, thereby reducing the cost required for manufacturing the power device and the space required for installation.

[0059] When the adsorption range of the adsorption cylinder 19 needs to be changed, the push block 35 is driven to slide on the rocker arm 29 by the first cylinder 33, so that the limit block 36 provided at the end of the push block 35 slides out of the slot 32, thereby releasing the restriction on the relative sliding between the rocker arm 29 and the slide bar 31. At the same time, the second cylinder 34 is extended and retracted to drive the slide bar 31 to slide relative to the rocker arm 29, so that the overall length of the rocker arm 29 and the slide bar 31 changes, thereby changing the range of movement of the adsorption cylinder 19, so that the adsorption cylinder 19 usually performs local cleaning of the area with more impurities, and cooperates with the periodic full-range cleaning of the adsorption cylinder 19 to further improve the efficiency of cleaning the first filter screen 5 and improve the cleaning effect of the area with more impurities.

[0060] Finally, the push block 35 is driven to reset by the first cylinder 33, so that the limit block 36 enters the corresponding notch 32, restricting the movement of the slide rod 31 relative to the rocker rod 29, thereby ensuring the stability of the overall structure and improving the effect of cleaning the first filter 5.

[0061] Example 4

[0062] On the basis of Example 1, Figure 9 、 Figure 10 and Figure 11As shown, when the reverse osmosis membrane 7 needs to be replaced, the screw 46 is loosened to drive the pressing block 45 to slide on the fixing rod 38, thereby releasing the restriction of the sliding of the limiting rod 41 on the fixing rod 38, and then the fixing rod 38 is rotated on the reverse osmosis filter tank 6 to drive the limiting rod 41 to move together, so that the first conical surface 42 provided at the end of the limiting rod 41 contacts the limiting groove 40, until the component force generated drives the limiting rod 41 to slide inward and compresses the second spring 43, thereby releasing the fixation of the reverse osmosis membrane 7 by the fixing rod 38, and at the same time, the rebound force generated by the compression of the first spring 37 drives the reverse osmosis membrane 7 to pop out, which is convenient for subsequent replacement of the reverse osmosis membrane 7 and prevents the reverse osmosis membrane 7 from being unable to work due to scale adhering to the surface of the reverse osmosis membrane 7 after long-term use, thereby improving the stability of the overall structure of the reverse osmosis equipment and improving the effect of preparing pure water;

[0063] When it is necessary to fix the reverse osmosis membrane 7, the replaced reverse osmosis membrane 7 is placed in the corresponding position of the reverse osmosis filter tank 6, and the fixing rod 38 is retracted so that the protrusions 39 provided on the fixing rod 38 are respectively in contact with the two sides of the reverse osmosis membrane 7, thereby limiting the movement of the reverse osmosis membrane 7 on the reverse osmosis filter tank 6, and then the screw 46 is rotated, and the T-block provided at the end of the screw 46 contacts the T-slot provided at the end of the pressure block 45, and the component force generated drives the pressure block 45 to slide on the fixing rod 38 until the second conical surface provided at the end of the pressure block 45 contacts the wedge block 44 provided at the end of the limiting rod 41, and the resistance generated limits the movement of the limiting rod 41 inward, and cooperates with the resistance generated after the limiting rod 41 contacts the limiting groove 40, further limiting the movement of the reverse osmosis membrane 7 on the reverse osmosis filter tank 6, avoiding external force from accidentally acting on the reverse osmosis membrane 7, and releasing the fixing effect of the fixing rod 38 on the reverse osmosis membrane 7, affecting the subsequent effect of the reverse osmosis membrane 7 in removing salt from water, thereby improving the effect of preparing pure water.
