Description

Technical Field

[0001] The present invention relates to the technical field of sewage recovery, and in particular to a concentrated water recovery device of a reverse osmosis component. Background Art

[0002] The common product structure of reverse osmosis technology in water treatment is: a central tube with multiple holes, and a reverse osmosis filter element formed by alternating layers of reverse osmosis membranes and a guide net wound on the central tube. Raw water enters the reverse osmosis membrane element from one end of the shell. Under the action of pressure, a portion of the water is filtered through the reverse osmosis membrane and becomes pure water, which enters the central tube and flows out from one end of the central tube. The concentrated water flows out from the other end of the shell.

[0003] During wastewater treatment, a housing encloses several reverse osmosis filter modules connected in series. During operation, wastewater flows in from one end of the housing and out from the other. During this process, the reverse osmosis filter modules near the inflow end accumulate more colloids or sediment, while those near the outflow end accumulate less sediment. This can easily lead to clogging at the water inlet of the housing, rendering the entire reverse osmosis filter module unusable and requiring replacement, resulting in wasted reverse osmosis filter modules at the rear end of the housing.

DETAILED DESCRIPTION

[0039] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0040] This embodiment provides a concentrated water recovery device for a reverse osmosis module, which is mainly used to improve the utilization rate of each osmosis module.

[0041] Under normal circumstances, since multiple osmotic components 1 are encapsulated in series inside a shell, the osmotic component 1 near the water inlet end of the shell is usually easily blocked by sediment or colloid in the raw water, and the entire shell and the osmotic component 1 inside the shell need to be replaced, which easily causes waste of the osmotic component 1 at the rear end of the shell.

[0042] In this embodiment, the installation method of the permeation component 1 is changed, and the packaging of the shell is omitted, thereby solving the problem that the permeation component 1 inside the shell is not easy to disassemble and assemble.

[0043] like Figure 2 、 Figure 3 and Figure 7 As shown, the osmosis assembly 1 includes a water collecting pipe 10, a reverse osmosis membrane 11, a water inlet spacer 12 and a sealing guide strip 13, wherein the reverse osmosis membrane 11 is folded in half, and then the water inlet spacer 12 is laid between the folded reverse osmosis membranes 11, and the water inlet spacer 12 reserves a gap between the two reverse osmosis membranes 11 for raw water to flow downstream; when the water inlet spacer 12 is clamped between the two reverse osmosis membranes 11, as shown in FIG. Figure 5 As shown, the sealing guide strip 13 is installed on the reverse osmosis membrane 11 on one side, so that the sealing guide strip 13 leaves an opening on the side facing the water collecting pipe 10, and then the sealing guide strip 13 and the reverse osmosis membrane 11 are wound on the water collecting pipe 10; during the winding process, as shown in FIG. Figure 6 As shown, a reflux channel 14 flows out between the sealing guide strip 13 and the inner reverse osmosis membrane 11, wherein a plurality of water collection holes 103 are provided on the side wall of the water collecting pipe 10, and the water collection holes 103 are connected with the reflux channel 14 at this time; the turbulent raw water from the water inlet screen 12 position becomes pure water under the osmosis of the reverse osmosis membrane 11 and flows into the reflux channel 14, and then, the pure water inside the reflux channel 14 converges into the water collecting pipe 10 through the water collection holes 103, and then flows out through the water collecting pipe 10.

[0044] It is worth noting that when the reverse osmosis membrane 11 is completely wound around the water collecting pipe 10, the water at the outermost water inlet screen 12 will flow outwards through the osmosis of the reverse osmosis membrane 11, which may easily cause waste of pure water. Figure 2 and Figure 7 As shown, when the reverse osmosis membrane 11 is completely wrapped around the outside of the water collecting pipe 10, the osmosis component 1 becomes cylindrical, and a sealing tube 15 is sleeved on the outside of the osmosis component 1, and a first cable tie 16 is provided at both ends of the sealing tube 15. The sealing tube 15 is fixed to the outside of the osmosis component 1 by using the first cable tie 16 to encapsulate the reverse osmosis membrane 11, thereby preventing pure water from flowing out from the outermost reverse osmosis membrane 11 and solving the problem of pure water waste.

[0045] When pressure is applied radially along the water collecting pipe 10 , the reverse osmosis membrane 11 will squeeze the water inlet screen 12 sandwiched therebetween, thereby reducing the gap between the two reverse osmosis membranes 11 and affecting the speed at which raw water flows through the water inlet screen 12 .

[0046] Therefore, in this embodiment, if Figure 3 and Figure 4 As shown, the sealing guide strip 13 includes a main sealing strip 131 and a secondary sealing strip 132, wherein the main sealing strip 131 is in a horizontal U-shape with an opening toward one side of the water collecting pipe 10. When the main sealing strip 131 is wound, the main sealing strip 131 is located at both end positions of the infiltration component 1, and the U-shaped bottom main sealing strip 131 is arranged along the length direction of the water collecting pipe 10 to block the return channel 14, thereby forming a vortex shape with one end closed in the cross section of the return channel 14, so that the raw water inside the return channel 14 is gathered toward the water collecting pipe 10; wherein, several secondary sealing strips 132 are fixed on the U-shaped main sealing strip 131. At this time, several secondary sealing strips 132 are distributed in sequence along the axial direction of the water collecting pipe 10 and wound around the water collecting pipe 10. The installation of multiple secondary sealing strips 132 can increase the radial load borne by the infiltration component 1, and avoid the problem that the water inlet screen 12 is squeezed and affects the raw water flow rate.

[0047] In order to facilitate the use of the first tie 16 to fix the sealing tube 15 on the outside of the permeation assembly 1, in this embodiment, as shown in FIG. Figure 3 and Figure 4 As shown, the main sealing strip 131 is further provided with two bundling sections 133, wherein the bundling sections 133 connect the side and bottom of the U-shaped main sealing strip 131, and a bundling groove 1331 is reserved on the bundling section 133. When the bundling section 133 is wrapped around the outside of the water collecting pipe 10, the bundling section 133 just wraps around the infiltration component 1 for one circle, and the bundling groove 1331 opens radially outward along the water collecting pipe 10. When the sealing tube 15 is fixed, the first tie 16 is sleeved in the bundling groove 1331, which can solve the problem of the first tie 16 jumping out of position and improve the stability of the sealing tube 15 fixation.

[0048] In this embodiment, multiple osmosis modules 1 are still connected in series to filter the raw water. In order to allow the pure water filtered by two adjacent osmosis modules 1 to continue to flow downstream, the water collecting pipes 10 in the two adjacent osmosis modules 1 need to be connected.

[0049] Therefore, in this embodiment, if Figure 2 and Figure 3As shown, one end of the water collecting pipe 10 is a connecting pipe end 101, and the other end of the water collecting pipe 10 is a pipe inserting end 102, wherein the inner diameter of the connecting pipe end 101 is equal to the outer diameter of the pipe inserting end 102. Specifically, the outer wall of the pipe inserting end 102 is provided with an external thread, and the inner wall of the connecting pipe end 101 is provided with an internal thread. When two adjacent permeation components 1 are installed, it is necessary to thread the pipe inserting end 102 of the permeation component 1 with the connecting pipe end 101 of the other permeation component 1, thereby realizing the assembly of the water collecting pipes 10 on the two adjacent permeation components 1, thereby ensuring that pure water continues to flow downstream.

[0050] The raw water passes through the gap formed between the water inlet screen 12 and the reverse osmosis membrane 11 and becomes concentrated water and flows backward. At this time, the concentrated water flows out of the water collecting pipe 10. In order to ensure that the concentrated water flowing out of the previous osmosis component 1 flows smoothly to the water inlet screen 12 of the next osmosis component 1, in this embodiment, as shown in FIG. Figure 1 As shown, a connecting pipe 2 is provided between two adjacent permeation components 1 and is sleeved on the outside of the water collecting pipe 10. Specifically, as shown in FIG. Figure 8 and Figure 11 As shown, the connecting pipe 2 includes a processing pipe section 21 and a connecting pipe section 22 connected to both ends of the processing pipe section 21, wherein the connecting pipe section 22 also includes a second tie 27 for fixing the connecting pipe section 22 to the outer wall of the permeation component 1.

[0051] Through the above-mentioned arrangement, the concentrated water flowing out from the end of the previous osmosis component 1 enters the processing pipe section 21 through the connecting pipe section 22, and then flows again to the water inlet screen 12 of the next osmosis component 1, thereby flowing the concentrated water into the gap between the water inlet screen 12 and the reverse osmosis membrane 11, realizing multi-stage treatment of the concentrated water, improving the recovery rate of pure water, and smoothly transferring the concentrated water in the previous osmosis component 1 to the next osmosis component 1.

[0052] In order to realize the connection between the connecting pipe 2 and the permeation assembly 1, in this embodiment, as shown in FIG. Figure 2 and Figure 4 As shown, there are two groups of bundling grooves 1331 on the bundling section 133. When the connecting pipe section 22 on the connecting pipe 2 is connected to the infiltration component 1, the second tie 27 is clamped in the other bundling groove 1331 to fix the connecting pipe 2 and the infiltration component 1.

[0053] Through the above arrangement, when the raw water is being processed, the raw water is pressed inward from one end of the osmosis component 1 by using a high-pressure pump. At this time, the raw water flows to the gap between the water inlet screen 12 and the reverse osmosis membrane 11. The raw water is filtered through the reverse osmosis membrane 11 to form pure water which converges into the water collecting pipe 10. The raw water flows out through the other end of the osmosis component 1 to form concentrated water, and then continues to flow to the next osmosis component 1 through the connecting pipe 2 for multiple treatments, thereby improving the recovery rate of pure water.

[0054] When the osmotic component 1 of the front section causes an increase in colloid or sediment after long-term use, which affects the recovery of pure water, the osmotic component 1 needs to be replaced. At this time, it is only necessary to remove the connecting pipes 2 on both sides of the corresponding osmotic component 1, and then the osmotic component 1 that needs to be replaced can be removed and replaced. Compared with the original replacement of the osmotic component 1 inside the entire shell, the service life of the remaining osmotic components 1 can be increased.

[0055] Under normal circumstances, before the raw water enters the osmosis component 1 for treatment, it is necessary to filter out large particles in the raw water and soften the raw water at the same time to avoid the accumulation of impurities or sediments in the water at the reverse osmosis membrane 11 of the osmosis component 1 as much as possible, and to avoid clogging of the osmosis component 1. The treated concentrated water will flow into the water reservoir and then be precipitated. In this process, a large site space is required, which cannot improve the utilization rate of the space.

[0056] Therefore, in this embodiment, if Figure 1 、 Figure 8 and Figure 9 As shown, a drug storage cartridge 26 is installed on the processing pipe section 21, wherein the drug storage cartridge 26 is filled with drugs that promote the precipitation of impurities in the concentrated water. The bottom wall of the processing pipe section 21 is also connected to a downwardly extending sewage discharge component 3, which is used to pre-collect the condensed impurities and then discharge the precipitate outward.

[0057] Specifically, in order to prevent the sediment from flowing to the next infiltration component 1 and causing blockage of the next infiltration component 1, in this embodiment, a blocking plate 28 is provided in the processing pipe section 21, wherein the blocking plate 28 is located on the front side of the next infiltration component 1 to prevent the sediment from flowing to the next infiltration component 1 and to block the sediment in the processing pipe section 21, so that the sediment falls into the sewage discharge component 3 under the action of gravity.

[0058] Specifically, in order to facilitate the installation of the drug storage cartridge 26, in this embodiment, as shown in FIG. Figure 12 As shown, a connecting seat 24 is fixedly provided on the top wall of the processing pipe section 21, wherein the connecting seat 24 is provided with a threaded interface. At this time, the drug storage cartridge 26 is installed at the threaded interface position of the connecting seat 24, and the drug storage cartridge 26 is inverted at the same time, and the liquid medicine inside the drug storage cartridge 26 is added to the inside of the processing pipe section 21.

[0059] In order to accurately control the amount of medicine added to the treatment pipe section 21, in this embodiment, a control valve is further provided inside the connecting seat 24, wherein one end of the control valve is connected to the medicine storage cylinder 26, and the other end is connected to the inner cavity of the treatment pipe section 21. A flow sensor 25 is also provided in the treatment pipe section 21 to record the volume of concentrated water discharged by the osmosis component 1, and then transmit the discharged concentrated water information to the central control unit, which processes the information and then realizes the opening and closing of the control valve, thereby controlling the amount of liquid medicine added and realizing the precipitation of impurities in the concentrated water.

[0060] Since the raw water is transported to the inside of the osmosis component 1 by a high-pressure pump, the concentrated water flowing out of the osmosis component 1 will continue to flow to the next osmosis component 1, and the impurities precipitated in the processing pipe section 21 are likely to adhere to the barrier plate 28.

[0061] Therefore, in this embodiment, if Figure 12 and Figure 16 As shown, an axial flow blade 29 is rotatably connected in the inner cavity of the processing pipe section 21, wherein a cleaning plate 291 is fixedly provided on the axial flow blade 29 and abuts against the baffle plate 28. It is worth noting that the axial flow blade 29 and the cleaning plate 291 are installed at the upstream position of the baffle plate 28.

[0062] Through the above arrangement, when the concentrated water flows toward the next permeation component 1, the flow of the concentrated water will drive the axial flow blades 29 to rotate, thereby driving the relative movement of the cleaning plate 291 and the baffle plate 28. At this time, the cleaning plate 291 can scrape down the colloid or sediment attached to the baffle plate 28, thereby reducing the risk of the baffle plate 28 being blocked.

[0063] In order to realize the installation of the baffle plate 28 and the axial flow blade 29, in this embodiment, as shown in FIG. Figure 13 As shown, the inner wall of the processing pipe section 21 is provided with a positioning retaining ring 23 extending radially inward, and the baffle plate 28 is fixedly mounted on the positioning retaining ring 23 by bolts; since the water collecting pipes 10 between the two adjacent permeation components 1 are connected by threaded connection, in order to prevent the water collecting pipes 10 from interfering with the installation of the baffle plate 28, in this embodiment, as shown in FIG. Figure 14 As shown, a positioning sleeve 281 is fixedly provided on the baffle plate 28 and arranged along the axial direction of the baffle plate 28. When the baffle plate 28 is installed, the positioning sleeve 281 passes through the water collecting pipe 10 to prevent the setting of the water collecting pipe 10 from affecting the installation of the baffle plate 28.

[0064] It is worth noting here that the axial flow blades 29 are rotatably mounted on the peripheral wall of the positioning sleeve 281 .

[0065] Since the sediment will fall down under the action of gravity, when the connecting pipe 2 is installed, the sewage discharge assembly 3 should be installed just below the connecting pipe 2. At this time, in this embodiment, Figure 2 As shown, the outer wall of the pipe end 101 is provided with a positioning groove 1011 arranged along the axial direction of the water collecting pipe 10, wherein the positioning grooves 1011 are provided in a plurality and are evenly distributed along the circumference of the water collecting pipe 10. Specifically, in this embodiment, the positioning grooves 1011 are provided in four groups, such as Figure 14 As shown, a positioning block 282 is fixedly provided on the inner wall of the positioning sleeve 281. When the connecting pipe 2 is installed, the positioning sleeve 281 is passed onto the water collecting pipe 10, and then the positioning block 282 is slid into the positioning groove 1011, so that the sewage discharge component 3 can be located directly below the connecting pipe 2, which is convenient for the preliminary collection of sediment and the discharge of sediment.

[0066] In order to collect the sediment generated in the connecting pipe 2 and perform preliminary storage, in this embodiment, as shown in FIG. Figure 9 and Figure 10 As shown, the sewage discharge assembly 3 is a sewage discharge pipe installed on the bottom wall of the connecting pipe 2, wherein the sewage discharge pipe includes a guide chamber 31 connected to the connecting pipe 2, and a receiving chamber 33 and a sewage discharge chamber 34 are sequentially provided below the guide chamber 31, wherein the sewage discharge assembly 3 is further provided with a plugging assembly 4 that moves up and down, wherein the plugging assembly 4 is provided with a first plugging seat 42 and a second plugging seat 44 for plugging the guide chamber 31 and the sewage discharge chamber 34. When sediment needs to be accumulated in the receiving chamber 33, the first plugging seat 42 connects the guide chamber 31 and the receiving chamber 33, and the second plugging seat 44 closes the passage between the receiving chamber 33 and the sewage discharge chamber 34, and the sediment formed in the processing pipe section 21 will fall into the guide chamber 31, and then the sediment will pass over the first plugging seat 42 and enter the receiving chamber 33, thereby gathering the sediment in the receiving chamber 33;

[0067] When the sediment in the storage chamber 33 accumulates to a certain amount, the blocking assembly 4 moves downward, and the first blocking seat 42 blocks the passage between the diversion chamber 31 and the storage chamber 33. The second blocking seat 44 is used to open the passage between the storage chamber 33 and the sewage chamber 34. At this time, the sediment accumulated in the storage chamber 33 falls into the sewage chamber 34 under the action of its own gravity, thereby releasing the sediment.

[0068] It is worth noting here that while the sediment is discharged through the sewage discharge component 3, some of the concentrated water will be discharged downward. Here, the sediment discharged by the sewage discharge component 3 can be collected in a storage box or a storage tank, and then allowed to stand. The concentrated water on the surface can be returned to the connecting pipe 2 through a water pump to achieve continued processing of the concentrated water. Since the standing of the sediment and the secondary return of the concentrated water both use conventional technical means, they are not shown in the accompanying drawings.

[0069] In order to realize the up and down movement of the blocking component 4, in this embodiment, as shown in FIG. Figure 10 and Figure 15 As shown, the sealing assembly 4 also includes a cylinder 40 and a connecting shaft 41, wherein the connecting shaft 41 is placed vertically and fixedly connected to the first sealing seat 42 and the second sealing seat 44 at the same time, and the inner wall of the sewage discharge chamber 34 is also fixedly provided with a support seat 35, and the cylinder 40 is fixedly installed on the support seat 35, and the telescopic rod of the cylinder 40 is fixedly connected to the connecting shaft 41.

[0070] In order to use the first blocking seat 42 to block the passage between the diversion chamber 31 and the receiving chamber 33, and use the second blocking seat 44 to block the passage between the receiving chamber 33 and the sewage chamber 34, it is worth noting that Figure 10 and Figure 15 As shown, the diameters of the diversion chamber 31 and the sewage chamber 34 are both larger than the diameter of the receiving chamber 33, wherein a first diversion surface 311 is provided at the bottom of the diversion chamber 31, wherein the first diversion surface 311 is an inverted conical surface, and a blocking conical surface 341 is provided at the top of the sewage chamber 34, wherein the blocking conical surface 341 is an upright conical surface, and a first blocking surface 421 adapted to the first diversion surface 311 is provided on the first blocking seat 42, and a second blocking surface 441 adapted to the blocking conical surface 341 is provided on the second blocking seat 44. When the sediment in the receiving chamber 33 is accumulated, as shown in FIG. Figure 9 As shown, the first blocking surface 421 is separated from the first guide surface 311, and the sediment in the guide chamber 31 can slide along the first guide surface 311 into the storage chamber 33. At this time, the second blocking surface 441 abuts against the blocking cone surface 341 to prevent the sediment in the storage chamber 33 from falling downward.

[0071] When the sediment in the storage chamber 33 needs to be discharged outward, the telescopic rod of the cylinder 40 is retracted, driving the connecting shaft 41 to move downward, and the first blocking surface 421 abuts against the first guide surface 311, closing the channel between the guide chamber 31 and the storage chamber 33. At this time, the second blocking surface 441 is separated from the blocking cone surface 341, and the sediment and concentrated water in the storage chamber 33 will be discharged outward under the action of gravity.

[0072] In order to better discharge the sediment accumulated in the diversion chamber 31 to the receiving chamber 33, in this embodiment, as shown in FIG. Figure 9 and Figure 15As shown, a second guide surface 422 is further provided on the first blocking seat 42, wherein the second guide surface 422 is an upright conical surface and is connected to the first blocking surface 421. When the sediment accumulated in the connecting pipe 2 falls downward, it will first fall on the second guide surface 422, and then the sediment will slide along the second guide surface 422 to the first guide surface 311, and finally guide the sediment into the receiving chamber 33 to prevent the sediment from accumulating in the guide chamber 31.

[0073] When the first blocking seat 42 blocks the passage between the receiving chamber 33 and the diversion chamber 31, the sediment cannot be completely discharged into the sewage chamber 34 by its own gravity. Therefore, in this embodiment, Figure 9 and Figure 10 As shown, a pressure chamber 32 is provided on the side wall of the top of the storage chamber 33, wherein the diameter of the pressure chamber 32 is larger than the diameter of the storage chamber 33, and the side wall of the pressure chamber 32 is provided with a pressure tube 321 connected to the outside world, and also includes a solenoid valve 36, one end of the solenoid valve 36 is connected to the pressure tube 321, and the other end of the solenoid valve 36 is connected to the external high-pressure air source through the air supply pipe 37; when the sediment inside the storage chamber 33 accumulates to a certain amount, the first blocking seat 42 closes the passage between the storage chamber 33 and the diversion chamber 31, and the second blocking seat 44 opens the passage between the storage chamber 33 and the sewage chamber 34, at this time the solenoid valve 36 is opened, and the external high-pressure air source enters the pressure chamber 32 through the pressure tube 321, forming high pressure at the top of the storage chamber 33, and then discharges the sediment into the sewage chamber 34 to prevent the sediment from remaining in the storage chamber 33.

[0074] In order to control the opening of the solenoid valve 36 and prevent the concentrated water in the pressure chamber 32 from entering the pressure pipe 321, in this embodiment, Figure 10 and Figure 15 As shown, the pressure tube 321 is installed on the side wall of the top of the pressure chamber 32, and a touch pressure sensor 38 is fixedly installed on the side wall of the bottom of the pressure chamber 32, wherein a sealing ring 43 is also fixedly connected to the connecting shaft 41. When the sediment accumulates in the storage chamber 33, the sealing ring 43 is located at the top of the pressure chamber 32 and blocks the pressure tube 321. When the connecting shaft 41 moves downward, the sealing ring 43 moves downward with the connecting shaft 41. At this time, the sealing ring 43 abuts against the touch pressure sensor 38, and the touch pressure sensor 38 transmits the signal to the central control unit, which controls the solenoid valve 36 to open, and then sends high-pressure gas to the pressure tube 321, thereby discharging the sediment from the storage chamber 33.

[0075] It is worth noting here that since the cylinder 40 with the connecting shaft 41 rises and falls rapidly, at this moment the sealing ring 43 releases the seal on the end of the pressure pipe 321, the solenoid valve 36 opens, and then the high-pressure gas is sent into the pressure pipe 321, which can reduce the risk of concentrated water backflowing into the pressure pipe 321.

[0076] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
