Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to an automated water treatment device connected in series in a secondary water supply system. Background Technology

[0002] Secondary water supply refers to the practice of storing and pressurizing urban public water supply or self-built water supply facilities, and then distributing it to users or for personal use through pipelines. Secondary water supply is primarily established to compensate for insufficient pressure in municipal water supply pipelines and to ensure water supply for residents living in high-rise buildings. Water entering the secondary water supply equipment passes through a filtration device and a backflow preventer before entering the booster pump, thus achieving the purpose of water supply. The equipment's principle is as follows: when the equipment's outlet pressure sensor detects that the pressure at the outlet is insufficient to meet the customer's water demand, the control system automatically controls the variable frequency speed-regulating pump set to start operation.

[0003] To ensure residents' water needs are met at all times, municipal water supply systems generally operate uninterruptedly and maintain a certain pressure within the pipelines. This includes the secondary water supply systems mentioned above, which primarily compensate for pressure deficiencies in the municipal water supply pipelines. Although municipal water has reached drinking water standards after systematic and efficient purification, the water in the secondary water supply system is supplied to the main water supply system from external sources. Therefore, the water quality of the secondary water supply indirectly determines the water quality of the municipal water supply system. Consequently, the compensation water from the secondary water supply system needs to undergo multi-stage purification treatment before entering the main water supply system. This involves removing pollutants and filtering out impurities to ensure the absolute safety of residents' drinking water.

[0004] Common automated water treatment devices for secondary water supply systems often use a series connection. The adsorbent material can generally be replaced periodically with relatively long intervals. However, in the filtration system, impurities gradually clog the filter pores, causing the water permeability to gradually decrease. Therefore, the filter screen needs to be cleaned regularly; otherwise, the blockage will worsen and may even affect the normal municipal water supply. However, since the filtration system is connected in series in the secondary water supply system, directly removing the filter screen for cleaning will prevent the compensation water during the filter cleaning process from being filtered. If the filter screen is not removed, it is very difficult to clean the clogged filter screen and remove the cleaned impurities from the water supply system. Therefore, the idea of ​​this invention is to find a way to fully clean the filter screen and fully remove the cleaned impurities without interrupting filtration or the secondary water supply.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing automated water treatment devices connected in series in the secondary water supply system. Summary of the Invention

[0006] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. Specifically, the invention aims to provide an automated water treatment device connected in series in a secondary water supply system. This addresses the aforementioned issue in the background where common automated water treatment devices for secondary water supply systems typically employ a series connection. While the adsorbent material can generally be replaced periodically with relatively long intervals, impurities in the filtration system gradually clog the filter pores, reducing water permeability. Therefore, the filter screen needs regular cleaning; otherwise, the blockage worsens and may even affect normal municipal water supply. However, in a secondary water supply system, directly removing the filter screen for cleaning would prevent the compensation water during the cleaning process from being filtered. Conversely, without removing the filter screen, effectively cleaning the clogged pores and removing the impurities from the water supply system is also extremely difficult.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automated water treatment device connected in series in a secondary water supply system, comprising a water supply pipe, wherein inlet branch pipes are symmetrically connected to the ends of the water supply pipes, and both ends of the inlet branch pipes are connected to a purified water chamber via a one-way valve; outlet branch pipes are symmetrically arranged on the sides of the purified water chamber, and both ends of the outlet branch pipes are connected to an outlet pipe; a movable plate is slidably arranged inside the purified water chamber via a rubber sealing ring, and the two movable plates are fixedly connected by a connecting column; a sewage discharge channel is opened at the center of the side of the purified water chamber, and an adaptive sewage discharge mechanism is installed inside the sewage discharge channel; the purified water chamber is circular and a turntable is concentrically arranged inside; and an adaptive elastic filter cloth water purification mechanism is arranged inside the purified water chamber.

[0008] Preferably, a solenoid valve is installed at the water passage of both the inlet branch pipe and the outlet branch pipe, and a controller is fixedly installed between the two water purification chambers, with a timing element inside the controller.

[0009] Preferably, the turntable has an annular groove on its outer side, and a limiting ball is provided at an equal angle inside the annular groove to slide with it, and the end of the limiting ball is fixed to the inner wall of the water purification tank.

[0010] Preferably, the adaptive sewage discharge mechanism includes a movable rod, a slot, a blocking plate, a telescopic rod, a cavity, an insert rod, and a guide rod. One end of the movable rod is fixed at the center of the surface of the movable plate, and the other end of the movable rod passes through the sewage discharge channel and is located on the outside of the clean water tank. The outer wall of the movable rod is symmetrically provided with slots, and a telescopic rod is installed through the inside of the side wall of the sewage discharge channel. The lower end of the telescopic rod passes through the sewage discharge channel and is fixedly connected to the blocking plate. The inside of the blocking plate is symmetrically provided with cavity, and an insert rod is slidably arranged inside the cavity. One end of the insert rod is engaged inside the slot, and the other end of the insert rod is installed through the outside of the blocking plate. A guide rod is arranged parallel to the side of the clean water tank.

[0011] Preferably, the outer wall of the telescopic rod is wound with a spring, one end of which is welded to the inner wall of the sewage channel, and the other end of which is fixed to the end of the telescopic rod. The cross-section of the inner end of the insertion rod is a quarter circle.

[0012] Preferably, the blocking plate is fitted and pressed against the outer port of the sewage channel by a rubber sealing ring, and the lower end of the guide rod is set in an outwardly flared arc shape, and the outer end of the insertion rod is slidably sleeved on the outer wall of the guide rod.

[0013] Preferably, the adaptive tension-adjustable filter cloth water purification mechanism includes an arc-shaped groove, a sliding rod, a fixing ring, and a filter cloth screen. The inside of the turntable is provided with an arc-shaped groove at equal angles. The sliding rod is fitted through the inside of the arc-shaped groove. The inside of the water purification chamber is provided with a groove that matches the large diameter end of the sliding rod. The fixing ring is concentrically provided on the inner side of the turntable and is fitted and fixed to the inner wall of the water purification chamber. The inside of the fixing ring is woven with a filter cloth screen made of chemical fiber filter cloth threads. One end of the chemical fiber filter cloth thread passes through the fixing ring and is fixedly connected to the inner ring of the turntable.

[0014] Preferably, the chemical fiber filter cloth filaments between the turntable and the fixed ring are inclined, and the chemical fiber filter cloth filaments are in a taut state. The slide rod is frustoconical, and the width of the arc groove is gradually set.

[0015] Compared with the prior art, the beneficial effects of the present invention are: Water from inside the water supply pipe is injected into the corresponding clean water chamber through the inlet branch pipe. At this time, the blockage plate seals the sewage discharge channel. Simultaneously, after being filtered by the filter cloth, the water exerts a squeezing effect on the movable plate. When the movable plate moves, it will simultaneously drive the three sets of sliding rods to slide along the inner walls of the corresponding three sets of arc-shaped grooves. When the frustum-shaped sliding rods squeeze the arc-shaped grooves with gradually changing width, they will generate an adaptive rotational pushing effect on the turntable through the arc-shaped grooves. When the turntable rotates adaptively outside the fixed ring, it will simultaneously tighten the ends of all filter lines of the filter cloth. The filter cloth is made of multiple sets of straight woven splices, and both ends of the straight lines pass through the fixed ring and are fixed to the inner wall of the turntable. Therefore, as the movable plate moves away, the filter cloth is gradually tightened to achieve the filtration effect. Conversely, the straight lines of the filter cloth will gradually loosen, thereby increasing the pore size.

[0016] Next, when the movable plate is pushed open to its maximum extent, the water, fully filtered by the filter mesh, enters the outlet pipe through the outlet branch pipe on the other side of the movable plate. Simultaneously, when the movable plate is pushed open to its maximum extent, it moves the movable rod, causing the ends of the two insert rods to fall precisely into the two slots and remain stable. The controller is designed with a timing module; when the timing ends, the controller controls the first and third solenoid valves to open, and the second and fourth solenoid valves to close. At this time, the states inside the two water purification chambers quickly switch. Water flows into the other water purification chamber in the same state as described above and is continuously supplied to the outlet pipe through the outlet branch pipe corresponding to the third solenoid valve. As the movable plate gradually opens under pressure, it pushes the movable plate inside the water purification chamber to fall in the opposite direction. When the movable plate returns to its original position, the three sets of sliding rods move in the opposite direction, causing the turntable to rotate in the opposite direction. This gradually loosens the multiple straight sections of the filter cloth, increasing its pore size. Simultaneously, when the movable plate returns to its original position, the movable rod, through its interlocking connection with the two insert rods, synchronously moves the blocking plate away from the drain channel, thus quickly opening the drain channel. The return of the movable plate pushes out the remaining water in the water purification chamber through the drain channel. The gushing water also pushes out any remaining impurities or particles that may be clogging the pores of the filter cloth. Meanwhile, the other water purification chamber continues the filtration and water supply process. This invention employs a dual-chamber structure with uninterrupted water supply in series on one side. While one chamber is supplying water, the other side begins to discharge waste. After a period of time, the water supply from both sides switches. Simultaneously, using a woven filter cloth, the filter pores tighten to their minimum during continuous filtration, while gradually expanding during waste discharge. Under the backwashing of residual water, impurities filtered from the clean water chamber are efficiently discharged. This also avoids the problem of impurities clogging the filter pores and requiring the filter screen to be removed for cleaning. Thus, it achieves efficient cleaning of the filter screen and thorough discharge of the cleaned impurities while ensuring uninterrupted filtration and secondary water supply.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-7 This invention provides a technical solution: an automated water treatment device connected in series in a secondary water supply system, including a water supply pipe 1, with inlet branch pipes 3 symmetrically connected to the ends of the water supply pipe 1, and each end of the two inlet branch pipes 3 connected to a clean water tank 5 via a one-way valve. Outlet branch pipes 4 are symmetrically arranged on the sides of the clean water tank 5, and each end of the outlet branch pipe 4 is connected to an outlet pipe 2. A movable plate 51 is slidably arranged inside the clean water tank 5 via a rubber sealing ring, and the two movable plates 51 are fixedly connected by a connecting column. A sewage discharge channel 52 is opened at the center of the side of the clean water tank 5, and an adaptive sewage discharge mechanism is installed inside the sewage discharge channel 52. The clean water tank 5 is circular and has a turntable 7 concentrically arranged inside, and an adaptive elastic filter cloth water purification mechanism is installed inside the clean water tank 5.

[0021] Solenoid valves are installed at the water passages of both the inlet branch pipe 3 and the outlet branch pipe 4, and a controller is fixedly installed between the two clean water tanks 5, with a timing element inside the controller.

[0022] An annular groove is provided on the outer side of the turntable 7, and a limiting ball 75 is provided at an equal angle inside the annular groove to match its sliding, and the end of the limiting ball 75 is fixed to the inner wall of the water purification tank 5.

[0023] The adaptive sewage discharge mechanism includes a movable rod 53, a slot 54, a blocking plate 6, a telescopic rod 61, a cavity 63, an insert rod 64, and a guide rod 65. One end of the movable rod 53 is fixed at the center of the surface of the movable plate 51, and the other end of the movable rod 53 passes through the sewage discharge channel 52 and is located on the outside of the clean water tank 5. The outer wall of the movable rod 53 is symmetrically provided with slots 54, and the telescopic rod 61 is installed through the inside of the side wall of the sewage discharge channel 52. The lower end of the telescopic rod 61 passes through the sewage discharge channel 52 and is fixedly connected to the blocking plate 6. The inside of the blocking plate 6 is symmetrically provided with cavity 63, and the insert rod 64 is slidably provided inside the cavity 63. One end of the insert rod 64 is engaged inside the slot 54, and the other end of the insert rod 64 is installed through the outside of the blocking plate 6. The guide rod 65 is arranged parallel to the side of the clean water tank 5.

[0024] The outer wall of the telescopic rod 61 is wrapped with a spring 62, one end of which is welded to the inner wall of the sewage channel 52, and the other end of which is fixed to the end of the telescopic rod 61. The inner end of the insertion rod 64 has a quarter circle cross section.

[0025] The blocking plate 6 is fitted and pressed against the outer port of the sewage channel 52 by a rubber sealing ring, and the lower end of the guide rod 65 is set in an outwardly flared arc shape, and the outer end of the insertion rod 64 is slidably sleeved on the outer wall of the guide rod 65.

[0026] The adaptive tension-adjustable filter cloth water purification mechanism includes an arc-shaped groove 71, a slide rod 72, a fixing ring 73, and a filter cloth screen 74. The inside of the turntable 7 is provided with an arc-shaped groove 71 at equal angles. The slide rod 72 is fitted through the inside of the arc-shaped groove 71. The inside of the water purification chamber 5 is provided with a groove that matches the large diameter end of the slide rod 72. The fixing ring 73 is concentrically provided on the inner side of the turntable 7 and is fitted and fixed to the inner wall of the water purification chamber 5. The inside of the fixing ring 73 is woven with chemical fiber filter cloth threads to form a filter cloth screen 74. One end of the chemical fiber filter cloth thread passes through the fixing ring 73 and is fixedly connected to the inner ring of the turntable 7.

[0027] The chemical fiber filter cloth filaments between the turntable 7 and the fixed ring 73 are inclined, and the chemical fiber filter cloth filaments are in a taut state. The slide bar 72 is frustoconical, and the groove width of the arc groove 71 is gradually set.

[0028] Working principle: When using this automated water treatment device connected in series in a secondary water supply system, such as Figure 2 As shown, at this time, the controller closes the first and third solenoid valves, and opens the second and fourth solenoid valves (see...). Figure 1 and Figure 2 (The numbers are marked in the middle). Water inside the water supply pipe 1 is injected into the corresponding clean water chamber 5 through the inlet branch pipe 3 where the second solenoid valve is located. At this time, the blockage plate 6 closes the sewage discharge channel 52. At the same time, after the water is filtered by the filter mesh 74, it exerts a squeezing effect on the movable plate 51. When the movable plate 51 is subjected to water pressure, it will adaptively slide and push another movable plate 51 to move in the opposite direction inside another clean water chamber 5. The specific function is described later. At this time, if... Figure 5 and Figure 6 As shown, when the movable plate 51 moves, it synchronously drives the three sets of sliding rods 72 to slide along the inner walls of the corresponding three sets of arc-shaped grooves 71. When the frustum-shaped sliding rods 72 compress the arc-shaped grooves 71 with gradually changing width, they will generate an adaptive rotational pushing effect on the turntable 7 through the arc-shaped grooves 71, such as... Figure 6 As shown, when the turntable 7 rotates adaptively outside the fixed ring 73, it will simultaneously tighten the ends of all filter lines of the filter cloth 74. The filter cloth 74 is made of multiple sets of straight woven splices, and both ends of the straight lines pass through the fixed ring 73 and are fixed to the inner wall of the turntable 7. Therefore, when the movable plate 51 moves away from the turntable 74, the filter cloth 74 is gradually tightened to achieve the filtering effect. Conversely, the straight lines of the filter cloth 74 will gradually loosen, thereby increasing the pore size.

[0029] Immediately afterwards, when the movable plate 51 is pushed open to its maximum extent, the water, which has been fully filtered by the filter mesh 74, will enter the outlet pipe 2 through the outlet branch pipe 4 on the other side of the movable plate 51. At the same time, when the movable plate 51 is pushed open to its maximum extent, as... Figure 2 and Figure 3 As shown, the movable plate 51 drives the movable rod 53 to move and makes the ends of the two insert rods 64 fall into the two slots 54 and remain stable.

[0030] The controller is designed with a timing module. When the timing ends, the controller controls the first and third solenoid valves to open and the second and fourth solenoid valves to close. At this time, the state inside the two water purification chambers 5 switches rapidly. Water flows into the other water purification chamber 5 in the same state as above and is injected into the water outlet pipe 2 through the outlet branch pipe 4 corresponding to the third solenoid valve for continuous water supply. Meanwhile, the movable plate 51 in the water purification chamber 5, which is gradually squeezed open, will push the movable plate 51 inside the above water purification chamber 5 to fall in the opposite direction. When the movable plate 51 returns to its original position, the three sets of sliding rods 72 move in the opposite direction, pushing the turntable 7 to rotate in the opposite direction. This causes the multiple straight lines of the filter cloth 74 to gradually loosen, thereby increasing its pore size. At the same time, when the movable plate 51 is reset, the movable rod 53 will synchronously drive the blocking plate 6 away from the sewage channel 52 through the plug-in engagement between the two plug rods 64, thereby causing the sewage channel 52 to open quickly. When the movable plate 51 is reset, the remaining water in the clean water tank 5 will be pushed out through the sewage channel 52. At the same time, the gushing remaining water will push out the impurities or particles that remain or are blocked in the pores of the filter cloth 74. At this time, the other clean water tank 5 is repeating the effect of filtering and supplying water.

[0031] At the same time, such as Figure 1 As shown, when the movable plate 51 is fully reset, the two insert rods 64 slide precisely onto the expanded outer end of the guide rod 65. The expanded outer end of the guide rod 65 pushes the two insert rods 64 away, releasing them from engagement with the slot 54. Once the engagement is released, under the reset action of the two springs 62, the blocking plate 6 will quickly reset to its original position. Figure 3 The state shown means that when the movable plate 51 falls to its reset position, the drain channel 52 opens, and when the movable plate 51 is fully reset, the drain channel 52 closes.

[0032] This invention employs a dual-chamber structure with uninterrupted water supply in series on one side. While one chamber is supplying water, the other side begins to discharge waste. After a period of time, the water supply from both sides is switched. Simultaneously, the woven filter cloth 74 is used. During continuous filtration, the filter pores tighten to their minimum size, while during waste discharge, the pores gradually expand. Under the backwashing of residual water, impurities filtered from the clean water chamber 5 are efficiently discharged. This also avoids the problem of impurities clogging the filter pores and having to remove the filter screen for cleaning. Thus, under the conditions of uninterrupted filtration and uninterrupted secondary water supply, the filter screen is efficiently cleaned and the cleaned impurities are fully discharged.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
