Description

Technical Field

[0001] The present invention relates to the technical field of pure water preparation, in particular to a pure water preparation device and method. Background Art

[0002] Pure water preparation uses a combination of various technologies and equipment to purify raw water, remove various impurities, ions and microorganisms, etc., to make it reach high purity standards, so as to meet the strict requirements of different industries such as electronics, pharmaceuticals, chemicals, laboratories, etc. for high-quality water sources, ensure the accuracy and stability of production and experimental processes, and thus ensure the quality of related products and the reliability of scientific research results. The water purification tank plays a role of storage, buffering and pollution prevention in pure water preparation. It can store pure water to meet the water demand at different times, balance the speed difference between water production and water use, ensure stable water supply, and use its sealed and sterile characteristics to prevent external impurities from contaminating pure water, ensuring that the water quality meets the high standards of various industries. In the pure water supply system, the water purification tank plays a vital role in flow rate regulation. Based on the inverse relationship between water volume and flow rate, when the water level in the water purification tank is at a high State, indicating that the water storage capacity is sufficient, in order to avoid a sudden increase in water-use pressure or unnecessary waste of water resources due to excessive flow rate, the water flow rate should be appropriately slowed down to maintain a stable and reasonable water supply rhythm. On the contrary, if the water level in the clean water tank is lowered and the water volume is small, the water flow rate needs to be accelerated to ensure that the current water demand can be met, and to prevent the adverse effects on water use in production, experiments and other links due to insufficient water supply, thereby ensuring the balance, efficiency and stability of the entire pure water supply process. In the process of adjusting the flow rate of the clean water tank, manual operation is currently used. The operator needs to rely on his own experience and real-time observation of the water use site, and manually control the corresponding adjustment device according to the changes in the water level in the clean water tank. The efficiency of manual operation is relatively low, which increases labor costs and time costs, and is not conducive to improving the overall production or experimental efficiency.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 2 to Figure 6 , which is the first embodiment of the present invention, provides a pure water preparation device and method, which includes a regulating component 200, a driving component 300 and a main component 100. The three can cooperate to adjust the flow rate of the water flow by the water level in the clean water tank without manual adjustment.

[0032] The adjustment assembly 200 includes an adjustment member 201, including a drainage tube 201a, a support tube 201b, an adjustment cage 201c, a drive block 201d and a hinged rod 201e. The support tube 201b is fixed in the drainage tube 201a, the adjustment cage 201c is arranged in the support tube 201b, the adjustment cage 201c and the support tube 201b are movably connected, the drive block 201d is fixed in the adjustment cage 201c, and the hinged rod 201e is hinged to the drive block 201d.

[0033] When there is a need to precisely control the water flow rate, the articulated rod 201e can be manipulated to generate displacement. The movement of the articulated rod 201e will drive the drive block 201d connected thereto to move synchronously, thereby driving the adjusting cage 201c to move linearly in the support tube 201b. When the adjusting cage 201c moves in the support tube 201b to a state of being tightly fitted with one end, the water flow channel becomes narrower accordingly, and the water flow rate slows down accordingly. When the adjusting cage 201c moves in the opposite direction and the degree of fit with the support tube 201b decreases, the water flow channel widens and the water flow rate speeds up. The water in the clean water tank 101 can be transmitted through the setting of the drainage pipe 201a. The drainage pipe 201a is connected to the water pipe and connected to other parts of the water purification system, so that the water after preliminary treatment or specific adjustment can flow smoothly to the subsequent links of the system.

[0034] The driving assembly 300 is arranged on the adjusting member 201, and includes a float 301a, an airbag 301b, an air tube 301c, a push plate 301d, a moving bar 301e and a floating plate 301f. The float 301a is arranged on the adjusting member 201, the airbag 301b is located at the bottom of the float 301a, the air tube 301c is fixed to the bottom of the airbag 301b, the push plate 301d is located in the air tube 301c, the moving bar 301e is fixed to the bottom of the push plate 301d, and the floating plate 301f is fixed to one end of the moving bar 301e.

[0035] When the position of the adjusting cage 201c needs to be adjusted, the water flow will push the float 301f. At this time, the movement of the float 301f can drive the moving bar 301e to move, and the movement of the moving bar 301e can drive the push plate 301d to move. At this time, the movement of the push plate 301d can transmit gas to the air pipe 301c, and the gas entering the air bag 301b can increase the water contact area. At this time, the air bag 301b can rise, and the water flow will contact the float 301a again, so as to generate sufficient lifting force. By rising the float 301a to the specified height, the adjusting cage 201c can be adjusted to a different position, so that the water flow rate can be adjusted.

[0036] The float 301f is made of high-density polyethylene, which has good corrosion resistance and can resist the erosion of chemical substances that may exist in the water. It has a low density and can easily float in the water. At the same time, its mechanical properties can ensure that it will not be easily damaged or deformed under the long-term push of the water flow, and can stably transmit the thrust of the water flow.

[0037] The float 301a is made of polystyrene foam, which has a very low density and excellent buoyancy. It can easily float in the water. It is relatively cheap and easy to shape. It can be processed into various shapes as needed. When it is acted upon by the rising force of the airbag 301b after increasing the contact area with the water, it can stably rise to a specified height.

[0038] Example 2

[0039] Reference Figure 2 to Figure 6 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0040] Specifically, the adjustment assembly 200 also includes a movable part 202, which is arranged on the hinge rod 201e. A rotating rod 202a is arranged at one end of the hinge rod 201e. The rotating rod 202a is hinged to one end of the hinge rod 201e, and a rotating column 202b is inserted at one side of the rotating rod 202a.

[0041] When the hinged rod 201e needs to be moved, the rotating rod 202a is rotated, and the rotating rod 202a can drive the hinged rod 201e to move. At this time, the movement of the hinged rod 201e can drive the adjustment cage 201c to move, so that the flow rate of water can be adjusted, and the rotating rod 202a can be driven to rotate by rotating the rotating column 202b.

[0042] Specifically, a positioning block 202c is provided at one end of the rotating column 202b, and the positioning block 202c and the rotating column 202b are rotatably connected through a bearing. A reel 202d is fixed at one end of the rotating column 202b, and a pull rope 202e is sleeved on the outer side of the reel 202d, and the pull rope 202e is fixed to the bottom of the float 301a.

[0043] The positioning block 202c is fixed to the inner wall of the support tube 201b. The positioning block 202c can be used to support the rotating column 202b to prevent the rotating column 202b from shifting during rotation. The rotating column 202b is respectively plugged into one side of the support tube 201b and the drainage tube 201a, and is rotatably connected to the two through a rotating shaft. A sealing ring is provided at the intersection of the rotating column 202b and the two to prevent water leakage. The movement of the float 301a can drive the pull rope 202e to move. At this time, the movement of the pull rope 202e can drive the reel 202d to rotate. The rotation of the reel 202d can drive the rotating column 202b to rotate. The pull rope 202e is plugged into the bottom of the connecting tube 302a and is movably connected to the connecting tube 302a. A sealing ring is provided at the bottom of the connecting tube 302a to prevent water leakage.

[0044] Specifically, a rotating bar 202f is fixed on one side of the reel 202d, a supporting shell 202g is sleeved on the outer side of the rotating bar 202f, the supporting shell 202g and the rotating bar 202f are rotatably connected via a bearing, and a torsion spring 202h is fixed on one side of the reel 202d, and the torsion spring 202h is fixed to the inner wall of the supporting shell 202g.

[0045] When the reel 202d rotates, the rotating bar 202f can be driven to rotate, and the rotation can apply a torsional force to the torsion spring 202h. At this time, the rotation of the reel 202d can drive the adjusting cage 201c to move. When the water level drops, the force of the rotation of the torsion spring 202h can drive the reel 202d to rotate, and the rotation of the reel 202d can drive the adjusting cage 201c to return to its original position, and the pull rope 202e can also be reeled in. The support shell 202g is fixed to one side of the drainage tube 201a. The rotating bar 202f can be supported by the setting of the support shell 202g. The support shell 202g is sleeved on the outside of the pull rope 202e. The support shell 202g and the pull rope 202e are movably connected, and the support shell 202g is fixed to the bottom of the connecting tube 302a.

[0046] Specifically, the driving assembly 300 also includes a connecting piece 302, which is arranged on the float 301a. A connecting pipe 302a is sleeved on the outside of the float 301a. A transmission pipe 302k is fixed to one side of the connecting pipe 302a. The float 301a is movably connected to the connecting pipe 302a.

[0047] There are two transmission pipes 302k, both of which are fixed on one side of the clean water tank 101. Through the setting of the transmission pipe 302k, the water in the clean water tank 101 can be transmitted to the connecting pipe 302a, so that the water level in the clean water tank 101 is flush with the connecting pipe 302a, and then the float 301a can be driven to different heights by injecting water into the connecting pipe 302a.

[0048] Specifically, a support column 302b is fixed in the connecting tube 302a, the support column 302b is plugged into the top of the float 301a, the support column 302b and the float 301a are movably connected, a spring 302c is fixed on the top of the float 301a, and the spring 302c is fixed to the inner wall of the connecting tube 302a.

[0049] When the float 301a moves, it will move on the support column 302b, thereby supporting the float 301a and preventing the float 301a from shifting during movement. When the float 301a moves, it can apply a squeezing force to the spring 302c. When the water level drops, the rebound force of the spring 302c can drive the float 301a to return to its original position.

[0050] Since the float 301a, the air bag 301b and the floating plate 301f are made of special materials, they have sufficient rising force in the water to overcome the elastic force of the spring 302c and the torsion spring 202h. When the water level drops and there is no water in the connecting pipe 302a, the float 301a can be supported by the setting of the spring 302c. At this time, the floating plate 301f can be suspended in the air, and the floating plate 301f will return to its original position, so that no gas will remain in the air bag 301b.

[0051] Example 3

[0052] Reference Figure 1 to Figure 6 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0053] Specifically, a support plate 302d is fixed to the bottom of the float 301a, and the airbag 301b is fixed in the support plate 302d.

[0054] The support plate 302d is provided to support the airbag 301b and prevent the airbag 301b from shifting. When no gas is retained in the airbag 301b, the long-term pressure on the airbag material is relieved. When the airbag is continuously inflated, the pressure of the internal gas will exert a continuous stretching effect on the airbag wall. Such stress over a long period of time may cause fatigue and aging of the airbag material, and even tiny cracks, ultimately leading to gas leakage. Allowing the airbag to be emptied of gas in a timely manner can reduce the impact of such continuous pressure, keep the performance of the airbag material stable for a longer period of time, and thus extend the service life of the airbag.

[0055] Specifically, it also includes a main body component 100, which is arranged on the transmission pipe 302k, including a clean water tank 101 and a water inlet frame 102. The clean water tank 101 is fixed to one side of the transmission pipe 302k, and the water inlet frame 102 is fixed to the top of the clean water tank 101.

[0056] The clean water tank 101 provides stable water pressure and water flow for the subsequent water use. It can balance the speed difference between pure water preparation and use. When the demand for water changes, the clean water tank 101 can use the stored water for buffering to ensure the continuity and stability of water supply. The water inlet frame 102 plays the role of guiding raw water into the entire pure water preparation system. It can introduce raw water into the clean water tank 101 to ensure that the water flow is evenly distributed to the subsequent purification equipment.

[0057] Specifically, a support leg 103 is fixed to the bottom of the clean water tank 101 .

[0058] There are three supporting legs 103 , all of which are fixed to the bottom of the clean water tank 101 . The setting of the supporting legs 103 can support the clean water tank 101 and prevent the clean water tank 101 from shifting.

[0059] Specifically, the raw water first passes through a sedimentation filter, where the filter screen intercepts large impurities such as silt, and then flows into an activated carbon filter to adsorb organic matter and residual chlorine. If the hardness of the raw water is too high, it enters a softener, where ion exchange resin is used to reduce the hardness, completing the pretreatment process.

[0060] The water then enters the reverse osmosis system, where it is pressurized by a high-pressure pump to penetrate the reverse osmosis membrane, pure water seeps out, and impurities are trapped. Sometimes it is further refined by ion exchange resins or electrodeionization equipment;

[0061] The water is then sterilized by an ultraviolet sterilizer, and large molecular impurities are removed by ultrafiltration as appropriate. The pure water is then stored in the clean water tank 101, and finally transferred from the clean water tank 101 to the drainage pipe 201a, and then the drainage pipe 201a transports the pure water to the point of use, ensuring that the entire process efficiently produces high-quality pure water.

[0062] After the raw water enters the pure water preparation system, it is first purified by intercepting large particles of impurities such as silt through the sediment filter, and then the activated carbon filter absorbs organic matter and residual chlorine. When the hardness of the raw water is too high, it enters the softener to reduce the hardness using ion exchange resin to complete the pretreatment. The water then enters the reverse osmosis system through a high-pressure pump, and the water molecules penetrate the reverse osmosis membrane, and the impurities are intercepted. Sometimes it is further refined by ion exchange resin or electrodeionization equipment, and then sterilized by ultraviolet disinfection. Depending on the situation, ultrafiltration is used to remove large molecular impurities. After that, the pure water is stored in the clean water tank 101, and finally transported from the clean water tank 101 to the point of use through the drainage pipe 201a, ensuring the output of high-quality pure water, meeting the water needs of industries such as electronic chip manufacturing, pharmaceuticals, and laboratory analysis, and providing basic guarantees for them.

[0063] When in use, raw water first enters the water inlet frame 102 , and the water inlet frame 102 introduces the raw water into the clean water tank 101 .

[0064] When the flow rate of water in the clean water tank 101 needs to be adjusted, the water flow will generate thrust on the floating plate 301f. The movement of the floating plate 301f drives the moving bar 301e fixed thereto to move. The movement of the moving bar 301e drives the push plate 301d to move in the air pipe 301c. The movement of the push plate 301d allows the gas to be transmitted to the air bag 301b through the air pipe 301c. After the air bag 301b is inflated, the water contact area increases, and an upward force is generated under the action of the water flow, driving the float 301a to rise. During the rising process of the float 301a, it is connected to the reel 202d through the pull rope 202e. The rising of the float 301a will pull the pull rope 202e, and the pull rope 202e drives the reel 202d to rotate. The rotation of 2d drives the rotating bar 202f to rotate and applies a torsional force to the torsion spring 202h. At the same time, the rotation of the reel 202d drives the hinged rod 201e to move through the transmission of the rotating column 202b and the rotating rod 202a. The movement of the hinged rod 201e drives the driving block 201d hinged thereto to move synchronously. The driving block 201d then drives the adjusting cage 201c to move linearly in the supporting tube 201b. When the adjusting cage 201c moves in the supporting tube 201b to a state of being tightly fitted with one end, the water flow channel becomes narrower accordingly, and the flow rate of water slows down accordingly; and when the adjusting cage 201c moves in the opposite direction and the degree of fit with the supporting tube 201b decreases, the water flow channel widens, and the flow rate of water speeds up.

[0065] When the water level drops, there is no water in the connecting pipe 302a. At this time, the spring 302c fixed on the top of the float 301a rebounds, driving the float 301a to return to its original position. The return of the float 301a causes the reel 202d to rotate through the pull rope 202e. The rotation of the reel 202d drives the adjustment cage 201c to return to its original position. At the same time, the rotation force of the torsion spring 202h also assists the reel 202d to rotate and reel in the pull rope 202e. In addition, the lowering of the water level causes the float 301f to lose the thrust of the water flow and become suspended in the air. The float 301f returns to its original position, and the gas in the airbag 301b is discharged without retaining any gas, thereby completing a complete flow rate regulation cycle. The entire device continuously and automatically adjusts according to the water level and water demand to ensure a stable supply of high-quality pure water and reasonable flow rate regulation to meet the water demand of the corresponding industry and ensure efficient and stable operation of the system.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.

If the hardness of the raw water is too high, it enters the softener and uses ion exchange resin to reduce the hardness, completing the pretreatment process; The water then enters the reverse osmosis system, where it is pressurized by a high-pressure pump to penetrate the reverse osmosis membrane, pure water seeps out, and impurities are trapped. Sometimes it is further refined by ion exchange resins or electrodeionization equipment; The water is then sterilized by an ultraviolet sterilizer and, if necessary, ultrafiltration is used to remove large molecular impurities. The pure water is then stored in a clean water tank (101) and finally transferred from the clean water tank (101) to a drainage pipe (201a). The drainage pipe (201a) then transports the pure water to the point of use, thereby ensuring that the entire process efficiently produces high-quality pure water.
