Description

[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 firstly introduced into the water treatment tank from the water inlet, and then the raw water passes through the filter barrel in turn, and the raw water is initially filtered through the first filter screen. Then the water after the preliminary filtration enters the reverse osmosis filter tank at the bottom of the water treatment tank, and the untreated water flows into the water inlet chamber through the guide plate provided 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, 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 equipment through the connecting pipe. I equipment combines 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 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 acid and alkali, completely getting rid of the problems of acid and alkali consumption, chemical waste liquid pollution, etc., 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 to drive 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 the outside of the adsorption cylinder, and adsorb 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 places, thereby improving the cleaning effect of the first filter screen, and at the same time, there is no need to frequently replace the first filter screen, 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 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 on the sliding block drives the adsorption tube located at the end of the adsorption tube to rotate, thereby enhancing the effect of adsorbing impurities; at the same time, the arc plate in the adsorption tube can expand the range of adsorption, and the arc plate collides with larger impurities, thereby breaking up relatively large impurities, and preventing large impurities from entering the adsorption tube and causing blockage;

[0019] 3. When the first filter needs to be cleaned, the first electric telescopic rod drives the movable rack to slide back and forth on the platform plate. Since the gear provided at the end of the rotating shaft is meshed with the movable rack, the rotating shaft is driven to rotate on the sliding block, and the adsorption tube 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, since the gear is meshed with the fixed rack at the same time, the sliding block is driven 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;

[0020] 4. Through the cooperation among the first motor, the swing rod, 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 meshed 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 swing rod and the slide rod is released through the cooperation among the first cylinder, the push block, the swing rod, the limit block and the notch, and at the same time, the second cylinder is extended and retracted to drive the slide rod to slide relative to the swing rod, so that the overall length of the swing rod and the slide rod 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 periodic full-range cleaning of the adsorption cylinder to further improve the efficiency of cleaning the first filter and improve the cleaning effect of the area with more impurities; finally, the first cylinder drives the push block to reset, so that the limit block enters the corresponding notch, restricting the movement of the slide rod relative to the swing rod, thereby ensuring the stability of the overall structure and improving the effect of cleaning the first filter;

[0022] 5. When the reverse osmosis membrane needs to be replaced, the fixing rod on the reverse osmosis membrane is released through the cooperation among the screw, the pressing 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 the subsequent replacement of the reverse osmosis membrane and prevents the reverse osmosis membrane from being unable to work due to scale attached 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 at 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 inward is restricted by the cooperation between the screw, the T-block, the pressure block, the T-slot, the fixing rod, the second cone surface and the wedge block, and the resistance generated after the limit rod contacts the limit slot further restricts the movement of the reverse osmosis membrane on the reverse osmosis filter tank, thereby avoiding external force from acting on the reverse osmosis membrane inadvertently and releasing the fixing effect of the fixing rod on the reverse osmosis membrane, thereby affecting the subsequent effect of the reverse osmosis membrane in removing salt from water, thereby improving the effect of preparing pure water.

[0051] Preferably, Figure 1 , Figure 2 and Figure 3 As shown, a raw water tank 51 is provided on the top of the water treatment tank 2, and the raw water tank 51 is provided with a water inlet pipe 52 connected with the water inlet 3, and a water pump 53 is provided on the water inlet pipe 52, so that the raw water inside the raw water tank 51 enters the water treatment tank 2 through the water pump 53; the adsorption cylinder 19 is provided with a third motor 54, and the movable end of the third motor 54 is connected to the fan blade 20 to provide power for the rotation of the fan blade 20.

[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 firstly 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 the raw water is initially filtered through the first filter screen 5, and then the water after the preliminary filtration 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 the preparation 11, the EDI device 11 integrates the electrodialysis technology and the ion exchange technology, and realizes the directional migration of ions under the action of the DC electric field through the selective permeation of anions and cations by the anion and cation exchange membranes and the exchange of ions by the ion exchange resins, thereby completing the deep desalination of water; in addition, the EDI device 11 and the reverse osmosis device are used to organically combine the traditional electrodialysis technology and the ion exchange technology, so as to continuously produce high-quality pure water, but without the use of acid and alkali, completely getting rid of the problems of acid and alkali consumption, chemical waste liquid pollution, etc., thereby realizing true clean production and reducing environmental pollution caused in the process of pure water preparation;

[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 arranged 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 the 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 on the fixed plate 1 3, so as to clean various places of the first filter screen 5, improve 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 shaft 18 rotates on the sliding block 17, driving 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, and 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 by the first electric telescopic rod 27 to slide back and forth on the platform plate 15. Since the gear 26 provided at the end of the rotating shaft 18 is meshed 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 meshed 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 swing rod 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 swing rod 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 meshed 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 and the fixed rack 24 are matched to drive the sliding block 17 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 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 swing rod 29 by the first cylinder 33, so that the limit block 36 provided at the end of the push block 35 slides out from the notch 32, and the restriction on the relative sliding between the swing rod 29 and the slide bar 31 is released. At the same time, the second cylinder 34 is extended and retracted to drive the slide bar 31 to slide relative to the swing rod 29, so that the overall length of the swing rod 29 and the slide bar 31 changes, thereby changing the activity range 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, so as 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 first cylinder 33 drives the push block 35 to reset, so that the limit block 36 enters the corresponding notch 32, restricting the movement of the slide bar 31 relative to the swing 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, Fig. 9 , Fig.10 and Fig.11As shown, when the reverse osmosis membrane 7 needs to be replaced, the screw rod 46 is loosened to drive the pressing block 45 to slide on the fixing rod 38, thereby releasing the restriction on 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 fixing of the fixing rod 38 to the reverse osmosis membrane 7, 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, so as to facilitate the subsequent replacement of the reverse osmosis membrane 7 and prevent 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 at 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 pressing block 45, and the component force generated drives the pressing block 45 to slide on the fixing rod 38 until the second conical surface provided at the end of the pressing 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 toward the inside, and cooperates with the resistance generated after the limiting rod 41 contacts the limiting groove 40, so as to further limit the movement of the reverse osmosis membrane 7 on the reverse osmosis filter tank 6, avoid external force from accidentally acting on the reverse osmosis membrane 7, and release the fixing effect of the fixing rod 38 on the reverse osmosis membrane 7, which affects the subsequent effect of the reverse osmosis membrane 7 in removing salt from water, thereby improving the effect of preparing pure water.
