Description

Technical Field

[0001] The invention relates to the field of water purification and filtration, in particular to a regional self-service water-taking device. Background Art

[0002] At present, urban residents use the following methods to meet their living needs for purified water: installing water purifiers at home, purchasing bottled purified water, using community self-service water vending machines, or drinking purified water directly at home. Among them, drinking purified water directly at home can solve the problem of purified water use for all residents in the unit building at one time.

[0003] However, the above-mentioned water extraction methods also have many defects, such as:

[0004] 1. When residents install water purifiers, they need to reserve space for the installation of water purification equipment, which is difficult for small-sized house owners. On the other hand, the cost is high. Not only do they need to buy water purifiers, but they also need to replace the filter cartridges regularly.

[0005] 2. When residents buy bottled water, the purchase cost includes not only the bottled water cost, but also the distribution cost. The price is high and cannot meet the user's requirement of using it at any time. In addition, bottled water has a shelf life and needs to be consumed within the shelf life.

[0006] 3. Residents get water from self-service water vending machines in the community. First, residents cannot monitor the water quality in time, or have no way of knowing whether the water quality meets the standards. Second, the water machines are exposed to the outdoors and the sanitary conditions are relatively poor. Third, during the off-season for water collection, water will remain in the water machines for a long time, and the water quality cannot be guaranteed to be safe and fresh. Fourth, the locations and numbers of self-service water vending machines are limited. Some residents have to get water from a relatively long distance, and carrying buckets for a long distance is labor-intensive, which is not very friendly to the elderly and infirm.

[0007] 4. The direct drinking water technology for residential communities that has been put into operation has a lot of problems. Because the pipes enter the homes through the corridors, it will also increase the renovation costs of the residents, affecting the overall appearance of the corridors and the interior of the residents. In addition, the construction technology is difficult, the process is complicated, the construction cost is high, the maintenance cost is high, and the water fee management is cumbersome. In addition, the wastewater generated is not properly treated and is directly discharged into the sewage pipe, resulting in a waste of water resources.

[0008] In the present invention, in view of the above-mentioned problems, a regional self-service water-drawing device is designed, which is set in the community. Through a series of filtration processes, tap water is converted into pure water and waste water. After the pure water passes through a pressure pump group and ultraviolet sterilization, it is supplied to the first-floor unit door of each unit building. A self-service water dispenser is installed in each unit building, and residents can swipe their cards to get water by themselves.

[0009] The filtration process generally includes quartz sand filtration, activated carbon filtration, precision filtration and reverse osmosis. The wastewater generated by the final filtration is used to irrigate the vegetation inside the community. In the activated carbon filtration process, the activated carbon adsorbs organic matter, odor, heavy metal ions, etc. in the tap water. A flow meter is installed on the water inlet pipe connected to the activated carbon filtration to count the amount of water flowing into the activated carbon filtration process. When the preset value is reached, the staff will be reminded to go for replacement, especially in the peak water season, when the activated carbon is replaced more frequently. When replacing the activated carbon, one staff member is often responsible for the replacement of activated carbon in multiple communities, and it is difficult to complete all the replacements within the specified time. If it is not replaced in time, the quality of the filtered water will be reduced, and it will affect a wide range of uses, involving the household water quality of many users.

[0056] Compared with residents installing water purifiers at home, the regional self-service water-drawing device in this embodiment can save installation space and reduce the cost of use; compared with purchasing bottled water, the regional self-service water-drawing device in this embodiment can allow residents to significantly reduce the cost of purchasing water; compared with taking water through self-service water vending machines in the community, the regional self-service water-drawing device in this embodiment can ensure that the water quality is monitored at any time, the water quality is safer and fresher, and residents can get water at a closer distance; compared with the community direct drinking water technology that has been put into production, because the pipeline does not go upstairs or into the house, there is no need to install a water metering device, on the basis of providing pure water of the same quality, the construction technology difficulty and construction period are greatly reduced. In addition, the waste water generated can be recycled and used for community greening and cleaning, thus achieving the purpose of saving water.

[0057] The specific use process of the activated carbon filter unit D designed in this embodiment is as follows:

[0058] One end of the butt joint pipe 8 is pressed against the end surface of the activated carbon cartridge 1, and the other end of the butt joint pipe 8 is connected to a water inlet pipe 11, water flows into the activated carbon cartridge 1 from the butt joint pipe 8, and fills the entire activated carbon cartridge 1, and a flow meter and a valve are installed on the water inlet pipe 11 to count the amount of water flowing into the activated carbon cartridge 1. When the water flow reaches a preset amount, the valve closes the water flow into the activated carbon cartridge 1, and then drives the motor 10, the motor 10 drives the screw rod 9 to rotate forward, and the screw rod 9 pushes the butt joint pipe 8 away from the activated carbon cartridge 1. When one end of the butt joint pipe 8 is separated from the activated carbon cartridge 1, the motor 3 drives the rotating shaft 2 to rotate, referring to Figure 8 , install and rotate clockwise, the bottom activated carbon cartridge 1 needs to be replaced, the rotating shaft 2 drives the support plate 5 to rotate ninety degrees clockwise, and the support plate 5 drives the right activated carbon cartridge 1 to rotate ninety degrees and rotate to the bottom position to realize the replacement of the activated carbon cartridge 1. After the replacement is completed, the motor 3 stops working, the motor 10 drives the screw rod 9 to reverse, and the screw rod 9 pulls the butt joint 8 to press against the end of the bottom activated carbon cartridge 1 at this time. When the butt joint 8 and the end of the activated carbon cartridge 1 are squeezed and sealed, the valve is opened. The valve can use an electric valve, which is controlled by the background central controller, and the water inlet pipe 11 connected to the butt joint 8 passes water, and the tap water A is effectively filtered by the activated carbon cartridge 1 again;

[0059] The support plate 5 is equipped with multiple activated carbon cartridges 1, which can filter more tap water A at one time. Even if the staff who replaces the activated carbon cartridge 1 fails to replace it in time, there are still multiple activated carbon cartridges 1 that can be used for a period of time, which not only frees up more time for the staff to replace it, but also ensures that the residents can drink clean water.

[0060] When replacing the activated carbon cartridge 1, the locking plate 7 is pushed, and the locking plate 7 slides along the arc-shaped slide groove 12 on the support plate 5. The locking plate 7 is no longer pressed on the outer surface of the activated carbon cartridge 1. At this time, the activated carbon cartridge 1 can be removed, and then a new activated carbon cartridge 1 is put in, and the locking plate 7 is pushed to constrain the activated carbon cartridge 1 in the installation groove 6 through the locking plate 7.

[0061] Reference Figure 8 - Fig.11 , each of the activated carbon cylinders 1 is provided with a plurality of groups of limiting plates 13, each limiting plate 13 is arc-shaped and is arranged along the same side of the outer surface of the activated carbon cylinder 1, and each group of limiting plates 13 is clamped on the support plate 5;

[0062] After the activated carbon cartridge 1 is installed on the support plate 5, the axial position of the activated carbon cartridge 1 needs to be determined so that the activated carbon cartridge 1 can rotate smoothly around the rotating shaft 2, and the end of the activated carbon cartridge 1 will not collide and interfere with the support frame 4 or the end of the docking end. For this purpose, a limit plate 13 is provided on the surface of the activated carbon cartridge 1, the activated carbon cartridge 1 is embedded in the mounting groove 6, and the support plate 5 is embedded in the gap between two adjacent limit plates 13. At this time, the axial position of the activated carbon cartridge 1 can be stabilized, and then the activated carbon cartridge 1 is radially locked in the mounting groove 6 by the locking plate 7.

[0063] Reference Figure 8 - Fig.11 , a plurality of U-shaped blocks 14 are also provided on the outer side wall of each activated carbon cylinder 1, and the U-shaped blocks 14 are arranged at the opposite side of each set of limit plates 13, and the end of the locking plate 7 can be embedded in the U-shaped block 14;

[0064] When the locking plate 7 locks the activated carbon cartridge 1 in the mounting groove 6, the end of the locking plate 7 will also be squeezed and embedded in the U-shaped block 14. The U-shaped block 14 constrains the locking plate 7, making the locking plate 7, the activated carbon cartridge 1 and the support plate 5 more integrated and more stable.

[0065] Reference Figure 1 - Fig.15 The end of the support structure is provided with a circular plate 15, and a through hole 16 is provided at the center of the circular plate 15. The inner circle of the through hole 16 is gap-matched with the outer circle of the rotating shaft 2. The circular plate 15 is connected to the support frame 4 through a spring 17, and the spring 17 is sleeved on the rotating shaft 2;

[0066] A clearance opening is provided in the middle of the lower half of the circular plate 15, and a rubber disc 18 is provided on the circular plate 15 at a position opposite to the end of the activated carbon cartridge 1. The rubber disc 18 is pressed on the end of the activated carbon cartridge 1, and a cleaning pipe 19 is connected to the back of the rubber disc 18, and the end of the cleaning pipe 19 passes through the circular plate 15;

[0067] When the activated carbon cartridge 1 filters and purifies the tap water A and reaches the level that requires replacement, there are filtered stains remaining in the activated carbon cartridge 1, and these stains will flow along the end of the activated carbon cartridge 1 to pollute the surrounding environment of the activated carbon filtration link. For this reason, a rubber disc 18 that can block the activated carbon cartridge 1 is provided. Under the elastic force of the spring 17 connected to it, the circular plate 15 squeezes the rubber disc 18 and squeezes the rubber disc 18 to the end of the activated carbon cartridge 1. A pair of rubber discs 18 are connected to a cleaning pipe 19 on the back side, and the pair of rubber discs 18 are arranged as follows: Figure 8 At the end of the left side activated carbon cylinder 1 shown, the cleaning pipe 19 is connected to the external air pump. The air pump injects dry hot air into the cleaning pipe 19 and dries the stains in the activated carbon cylinder 1. The stains are dried in the activated carbon cylinder 1 to avoid flowing out and polluting the environment.

[0068] Reference Figure 2 - Fig.13 The lower edge of one end of the butt joint pipe 8 is provided with an insertion rod 20, and the axis of the insertion rod 20, the axis of the butt joint pipe 8 and the axis of the rotating shaft 2 are arranged in the same vertical plane;

[0069] A plug hole 21 is formed on the side wall of each U-shaped block 14; an arc groove 22 is formed on one end surface of each locking plate 7, and the locking plate 7 slides into the U-shaped block 14, the arc groove 22 coincides with the plug hole 21, and the end of the insertion rod 20 can be inserted into the plug hole 21 and coincide with the arc groove 22;

[0070] When the new activated carbon cartridge 1 is rotated to a position relative to the docking tube 8, one end of the docking tube 8 is squeezed on the end of the activated carbon cartridge 1. At the same time, the docking tube 8 will also drive the two plug rods 20 to move. The ends of the plug rods 20 slide along the insertion holes 21 and are inserted into the arc grooves 22 on the locking plate 7. At this time, the plug rods 20 lock the locking plate 7 stably. Even if the water flow impacts the activated carbon cartridge 1 to generate vibration, the locking plate 7 can also stably lock the activated carbon cartridge 1 in the mounting groove 6.

[0071] Reference Figure 2 - Fig. 9 A card plate 23 is provided on the upper surface of the other end of the butt joint pipe 8; a plurality of card grooves 24 are evenly formed on the outer ring of the end of the rotating shaft 2, the butt joint pipe 8 is squeezed on the end of the activated carbon cartridge 1, and the card plate 23 slides into the card groove 24;

[0072] The butt joint tube 8 moves toward the end of the activated carbon cartridge 1, and at the same time, the butt joint tube 8 will also drive the clamping plate 23 thereon to move, and the clamping plate 23 will be embedded in the clamping groove 24 opened at the end of the rotating shaft 2. At this time, the clamping plate 23 will restrain the relative movement of the rotating shaft 2, so that the rotating shaft 2 is stabilized, that is, the rotating shaft 2, the activated carbon cartridge 1 and the butt joint tube 8 are connected into a whole, thereby improving the integrity and ensuring that the activated carbon filter unit D can operate stably and for a long time.

[0073] Reference Figure 2 - Fig.15 , each of the circular plates 15 is provided with a plurality of rubber discs 18;

[0074] A plurality of rubber discs 18 are arranged on the circular plate 15, and the rubber discs 18 are opposite to the ends of the activated carbon cartridges 1 one by one; the circular plate 15 squeezes the rubber discs 18 through the spring 17 connected thereto. If a rubber disc 18 is arranged on one side of the circular plate 15, the circular plate 15 will be tilted to the side, so that the rubber disc 18 cannot block the activated carbon cartridges 1 that have been filtered and discarded. At the same time, the ends of the remaining activated carbon cartridges 1 to be used are in an exposed state, and there is a possibility that foreign matter will enter the activated carbon cartridges 1. By arranging a plurality of rubber discs 18, each activated carbon cartridge 1 to be used and the activated carbon cartridges 1 that have been filtered and discarded can be effectively blocked by the rubber discs 18.

[0075] Reference Fig. 9 , a plurality of reinforcing plates 25 are evenly arranged between adjacent support plates 5, and the ends of the reinforcing plates 25 are vertically fixed to the support plates 5;

[0076] A reinforcing plate 25 is provided between adjacent supporting plates 5 , and the reinforcing plate 25 is used to enhance the stability of the supporting plate 5 for mounting the activated carbon cartridge 1 , thereby improving the overall strength of the activated carbon filter unit D.

[0077] Reference Fig.16 , a plurality of activated carbon filter units D are arranged side by side; the activated carbon filter units D can be arranged side by side to increase the activated carbon filtration efficiency, which can not only filter the water flowing into the water inlet pipe 11 in real time, but also meet the needs of the subsequent precision filter E, providing sufficient water source for the community.

[0078] Reference Fig.12 - Fig.13 A handle 26 is fixedly connected to the outer side wall of the end of each locking plate 7; a handle 26 is provided on the locking plate 7, and the sliding of the locking plate 7 can be achieved by pushing and pulling the handle 26, so as to facilitate the sliding control of the locking plate 7.

[0079] Working principle: One end of the butt joint pipe 8 is pressed against the end surface of the activated carbon cartridge 1, and the other end of the butt joint pipe 8 is connected to the water inlet pipe 11. The water inlet pipe 11 is installed with a flow meter and a valve to count the amount of water flowing into the activated carbon cartridge 1. When the water flow reaches a preset amount, the valve closes the water flow into the activated carbon cartridge 1, and then drives the motor 10. The motor 10 drives the screw rod 9 to rotate forward, and the screw rod 9 pushes the butt joint pipe 8 away from the activated carbon cartridge 1. When one end of the butt joint pipe 8 is separated from the activated carbon cartridge 1, the motor 3 drives the rotating shaft 2 to rotate. Figure 8 , install and rotate clockwise, the bottom activated carbon cartridge 1 needs to be replaced, the rotating shaft 2 drives the support plate 5 to rotate ninety degrees clockwise, and the support plate 5 drives the right activated carbon cartridge 1 to rotate ninety degrees and rotate to the bottom position to realize the replacement of the activated carbon cartridge 1. After the replacement is completed, the motor 3 stops working, the motor 10 drives the screw rod 9 to reverse, and the screw rod 9 pulls the butt joint 8 to press against the end of the bottom activated carbon cartridge 1 at this time. When the butt joint 8 and the end of the activated carbon cartridge 1 are squeezed and sealed, the valve is opened. The valve can use an electric valve, which is controlled by the background central controller, and the water inlet pipe 11 connected to the butt joint 8 passes water, and the tap water A is effectively filtered by the activated carbon cartridge 1 again;

[0080] The support plate 5 is equipped with multiple activated carbon cartridges 1, which can filter more tap water A at one time. Even if the staff who replaces the activated carbon cartridge 1 fails to replace it in time, there are still multiple activated carbon cartridges 1 that can be used for a period of time, which not only frees up more time for the staff to replace it, but also ensures that the residents can drink clean water.

[0081] When replacing the activated carbon cartridge 1, the locking plate 7 is pushed, and the locking plate 7 slides along the arc-shaped slide groove 12 on the support plate 5. The locking plate 7 is no longer pressed on the outer surface of the activated carbon cartridge 1. At this time, the activated carbon cartridge 1 can be removed, and then a new activated carbon cartridge 1 is put in, and the locking plate 7 is pushed to constrain the activated carbon cartridge 1 in the installation groove 6 through the locking plate 7;

[0082] After the activated carbon cartridge 1 is installed on the support plate 5, the axial position of the activated carbon cartridge 1 needs to be determined so that the activated carbon cartridge 1 can smoothly rotate around the rotating shaft 2, and the end of the activated carbon cartridge 1 will not collide with the end of the support frame 4 or the butt end. To this end, a limit plate 13 is provided on the surface of the activated carbon cartridge 1, the activated carbon cartridge 1 is embedded in the installation groove 6, and the support plate 5 is embedded in the gap between two adjacent limit plates 13. At this time, the axial position of the activated carbon cartridge 1 can be stabilized, and then the activated carbon cartridge 1 is radially locked in the installation groove 6 by the locking plate 7;

[0083] When the lock plate 7 locks the activated carbon cartridge 1 in the installation groove 6, the end of the lock plate 7 is also squeezed and embedded in the U-shaped block 14, and the U-shaped block 14 constrains the lock plate 7, so that the lock plate 7, the activated carbon cartridge 1 and the support plate 5 have a higher integrity and stronger stability;

[0084] When the activated carbon cartridge 1 filters and purifies the tap water A and reaches the level that requires replacement, there are filtered stains remaining in the activated carbon cartridge 1, and these stains will flow along the end of the activated carbon cartridge 1 to pollute the surrounding environment of the activated carbon filtration link. For this reason, a rubber disc 18 that can block the activated carbon cartridge 1 is provided. Under the elastic force of the spring 17 connected to it, the circular plate 15 squeezes the rubber disc 18 and squeezes the rubber disc 18 to the end of the activated carbon cartridge 1. A pair of rubber discs 18 are connected to a cleaning pipe 19 on the back side, and the pair of rubber discs 18 are arranged as follows: Figure 8 At the end of the left side activated carbon cartridge 1 shown, the cleaning pipe 19 is connected to the external air pump, and the air pump injects dry hot air into the cleaning pipe 19 to dry the stains in the activated carbon cartridge 1. The stains are dried in the activated carbon cartridge 1 to avoid flowing out and polluting the environment.

[0085] When the new activated carbon cartridge 1 rotates to a position opposite to the butt joint 8, one end of the butt joint 8 is pressed against the end of the activated carbon cartridge 1, and the butt joint 8 also drives the two plug rods 20 to move, and the ends of the plug rods 20 slide along the insertion holes 21 and are inserted into the arc grooves 22 on the locking plate 7. At this time, the plug rods 20 lock the locking plate 7 stably, and even if the water flow impacts the activated carbon cartridge 1 to generate vibration, the locking plate 7 can still stably lock the activated carbon cartridge 1 in the installation groove 6;

[0086] The butt joint pipe 8 moves toward the end of the activated carbon cartridge 1, and at the same time, the butt joint pipe 8 also drives the clamping plate 23 thereon to move, and the clamping plate 23 is embedded in the clamping groove 24 provided at the end of the rotating shaft 2. At this time, the clamping plate 23 constrains the relative movement of the rotating shaft 2, so that the rotating shaft 2 is stabilized, that is, the rotating shaft 2, the activated carbon cartridge 1 and the butt joint pipe 8 are connected into a whole, so as to improve the integrity and ensure that the activated carbon filter unit D can operate stably and for a long time;

[0087] A plurality of rubber discs 18 are arranged on the circular plate 15, and the rubber discs 18 are opposite to the ends of the activated carbon cartridges 1 one by one; the circular plate 15 squeezes the rubber discs 18 through the spring 17 connected thereto. If a rubber disc 18 is arranged on one side of the circular plate 15, the circular plate 15 will be tilted to the side, so that the rubber disc 18 cannot block the activated carbon cartridges 1 that have been filtered and discarded. At the same time, the ends of the remaining activated carbon cartridges 1 to be used are in an exposed state, and there is a possibility that foreign matter will enter the activated carbon cartridges 1. By arranging a plurality of rubber discs 18, each activated carbon cartridge 1 to be used and the activated carbon cartridges 1 that have been filtered and discarded can be effectively blocked by the rubber discs 18.
