Description

Technical Field

[0001] The invention relates to the technical field of water purification, and in particular to a reverse osmosis membrane filter. Background Art

[0002] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. The working principle is based on reverse osmosis technology. Under the action of pressure, the solvent (usually water) will flow from the high-concentration solution side through the reverse osmosis membrane to the low-concentration solution side, while the solute is blocked by the membrane, thereby achieving solution separation, purification and concentration.

[0003] A reverse osmosis membrane filter is a device that uses a reverse osmosis membrane to filter a solution. A cavity is opened inside the filter, and a liquid inlet is provided at one end, and a liquid outlet and a water outlet are provided at the other end. The reverse osmosis membrane is installed inside the cavity and divides the cavity into two parts. The first cavity is connected to the liquid inlet and the liquid outlet, and the second cavity is connected to the water outlet. After the solvent enters the first cavity of the reverse osmosis membrane filter through the liquid inlet, the water inside it will pass through the reverse osmosis membrane into the second cavity, and finally flow out from the water outlet, while the remaining solution and solute will flow out through the liquid outlet, waiting to be filtered again.

[0004] Since the density of the solute in the solution is greater than the density of water, when the solution enters the reverse osmosis membrane filter, the solute layer is usually located below the water layer. Under the obstruction of the solute, it is difficult for water to pass through the tiny gaps on the reverse osmosis membrane into the second cavity, resulting in a decrease in the filtration effect. In addition, traditional reverse osmosis membrane filters extend the filtration time of the solution by extending the length of the reverse osmosis membrane, thereby enhancing the filtration effect. However, the reverse osmosis membrane is thin and soft, and the extended reverse osmosis membrane is difficult to reinstall inside the reverse osmosis membrane filter, which is not convenient for practical use. Summary of the invention

[0018] As a further description of the above technology, a reverse osmosis membrane filter and a working method thereof: A reverse osmosis membrane filter working method comprises the following steps:

[0019] S: After turning the sealing cover to open, remove the reverse osmosis membrane that has been blocked after long-term use inside the cylinder, and then take out the sealing plate from the strip groove on the top of the cylinder;

[0020] S: Pass one end of the new reverse osmosis membrane through the strip groove of the cylinder until the end of the reverse osmosis membrane enters between the leather ring and the top plate. During this process, the reverse osmosis membrane must be kept flat, and the edges on both sides of the reverse osmosis membrane are located between the leather ring and the fixed ring. Twist one of the top plates to drive the other top plate to rotate synchronously through the belt. At this time, the leather ring circulates outside the two top plates to transport the reverse osmosis membrane to the inside of the cylinder until the reverse osmosis membrane surrounds the fixed ring.

[0021] S: Install the sealing plate and the sealing cover back to their original positions, and connect the liquid inlet pipe to the solution delivery pipe, and connect the liquid outlet pipe and the water outlet pipe to the solution output pipe and the external water storage system respectively;

[0022] S: After the solution is transported to the inside of the cylinder through the liquid inlet pipe, the thrust of the solution causes the impeller b to rotate, and the impeller b drives the water distribution plate to swing back and forth through the crank a, the transmission frame and the crank b to disperse the solution, so that the solution is fully in contact with the reverse osmosis membrane, and the water filtered by the solution passes through the reverse osmosis membrane and flows between the reverse osmosis membrane and the cylinder. The solution that is not completely filtered flows out through the liquid outlet pipe, and the filtered water flows out through the water outlet pipe;

[0023] S: The solution flowing out of the liquid outlet pipe drives the impeller a to rotate, and then drives the counterweight slider to make circular motion through the turntable, so that the counterweight slider slides under the action of centrifugal force.

[0024] In summary, due to the use of the above-mentioned technology, a reverse osmosis membrane filter and a working method thereof, the beneficial effects of the present invention are:

[0025] When the solution passes through the liquid inlet pipe, the impeller b is driven to rotate, and the water distribution plate is driven to swing back and forth through the crank a, the transmission frame and the crank b to disperse the solution, so that the solute in the solution is evenly mixed with the water, thereby alleviating the problem of filtration degradation caused by the solute being blocked between the water and the reverse osmosis membrane. In addition, driven by the swing of the reverse osmosis membrane, the solution inside the reverse osmosis membrane will be spread out and fully contact with the reverse osmosis membrane, thereby expanding the contact area between the solution and the reverse osmosis membrane, thereby improving the filtration efficiency of the solution.

[0026] Since the transmission frame passes through the path of the liquid inlet pipe, the transmission frame can hit and block the solution flowing out of the liquid inlet pipe when it swings back and forth, so that the solution is mixed evenly and the kinetic energy of the solution is reduced, and the time for the solution to stay in the device is delayed, thereby enhancing the effect of the reverse osmosis membrane filtering the solution;

[0027] The design of the fixing ring and the leather ring can smoothly transport the wide reverse osmosis membrane to the inside of the cylinder, reducing the difficulty of replacing the reverse osmosis membrane and solving the problems of tilt and wrinkles that are easy to occur during the installation of the wide reverse osmosis membrane, thus ensuring the use effect of the reverse osmosis membrane.

[0028] When the solution passes through the liquid outlet pipe, it pushes the impeller a to rotate, thereby driving the counterweight slider and the color block to make circular motion through the turntable, so that the color block forms a circular trajectory on the turntable. At the same time, the counterweight slider drives the color block and the turntable to slide relative to each other under the action of centrifugal force, and the diameter of the circular trajectory changes. Therefore, by observing the diameter of the circular trajectory, the rotation speed of the turntable and the impeller a can be intuitively judged, reflecting the flow rate of the solution in the liquid outlet pipe. Since the worse the filtering effect of the reverse osmosis membrane, the more solution is retained in the first cavity, and the faster the flow rate of the solution discharged from the liquid outlet pipe, this design can reflect the filtering effect of the reverse osmosis membrane, and facilitate timely replacement of the reverse osmosis membrane.

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 creative work are within the scope of protection of the present invention.

[0045] The present invention adopts the following technology, a reverse osmosis membrane filter:

[0046] The filter assembly 1 includes a cylinder 11, one end of the cylinder 11 is fixedly connected with a liquid inlet pipe 15, the other end of the cylinder 11 is provided with a water outlet pipe 13 and a liquid outlet pipe 14, a reverse osmosis membrane 12 is provided inside the cylinder 11, the reverse osmosis membrane 12 divides the internal cavity of the cylinder 11 into a first cavity and a second cavity, and the liquid outlet pipe 14 and the water outlet pipe 13 are respectively connected with the first cavity and the second cavity;

[0047] A uniform mechanism 4 for enhancing the solution filtering effect is installed inside the filter assembly 1. The uniform mechanism 4 includes an impeller b42 that is rotatably connected to the inside of the liquid inlet pipe 15 and rotates with the help of the impact force of the water flow. A crank a44 is fixedly connected to the outer side of the impeller b42. A transmission frame 43 and a crank b45 are rotatably connected inside the filter assembly 1. The ends of the crank a44 and the crank b45 that are close to each other are both embedded in the transmission frame 43. The other end of the crank b45 is fixedly connected to a water distribution plate 46 for distributing the water flow. When passing through the liquid inlet pipe 15, the impeller b42 is driven to rotate, and the water distribution plate 46 is driven to swing back and forth by the crank a44, the transmission frame 43 and the crank b45 to disperse the solution, so that the solute in the solution is evenly mixed with the water, thereby alleviating the problem of filtration degradation caused by the solute being blocked between the water and the reverse osmosis membrane 12. In addition, under the impetus of the swing of the reverse osmosis membrane 12, the solution inside the reverse osmosis membrane 12 will be spread out and fully contact with the reverse osmosis membrane 12, thereby expanding the contact area between the solution and the reverse osmosis membrane 12.

[0048] The filter assembly 1 is also provided with an installation mechanism 3 for facilitating the installation of the reverse osmosis membrane 12. The installation mechanism 3 includes a leather ring 33 for conveying the reverse osmosis membrane 12 and keeping it flat. The leather ring 33 and the fixing ring 34 clamp the reverse osmosis membrane 12. Therefore, the circular movement of the leather ring 33 can drive the reverse osmosis membrane 12 to move until the reverse osmosis membrane 12 surrounds the outside of the fixing ring 34.

[0049] A measuring mechanism 2 for displaying the filtering effect of the reverse osmosis membrane 12 is installed on the liquid outlet pipe 14 .

[0050] As a further description of the above-mentioned technology, a reverse osmosis membrane filter and its working method are described as follows: a limit frame 41 for supporting and reinforcing a transmission frame 43 is fixedly connected inside the filter component 1 to prevent the solution in the liquid inlet pipe 15 from flowing out and impacting the transmission frame 43, causing the transmission frame 43 to shift. The bottom end of the transmission frame 43 is rotatably connected to the inner wall of the filter component 1 and the transmission frame 43 passes through the path of the liquid inlet pipe 15. Therefore, when the transmission frame 43 swings back and forth, it can also hit and block the solution flowing out of the liquid inlet pipe 15, so that the solution is mixed evenly and the kinetic energy of the solution is reduced, delaying the time that the solution stays in the device, thereby enhancing the effect of the reverse osmosis membrane 12 filtering the solution.

[0051] As a further description of the above-mentioned technology, a reverse osmosis membrane filter and its working method: the installation mechanism 3 also includes a sealing plate 31, a strip groove is opened on the top of the cylinder 11, the sealing plate 31 is located inside the strip groove and both ends are respectively embedded in the inner wall of the strip groove, the connection between the sealing plate 31 and the strip groove is sealed, and a wide reverse osmosis membrane 12 can be directly inserted into the cylinder 11 through the strip groove, which is convenient for the installation of the reverse osmosis membrane 12.

When the reverse osmosis membrane 12 is installed, the two fixing rings 34 can suppress the edges on both sides of the reverse osmosis membrane 12 to prevent the edges of the reverse osmosis membrane 12 from warping up, restricting the position of the reverse osmosis membrane 12, and preventing the reverse osmosis membrane 12 from wrinkling and tilting during transportation. The leather ring 33 is sleeved on the two rotating parts 32 at the positions corresponding to the fixing rings 34, and a connecting rod 35 is fixedly connected between the fixing rings 34.

[0053] As a further description of the above-mentioned technology, a reverse osmosis membrane filter and its working method are as follows: a top plate 36 is fixedly connected to the top of the connecting rod 35, and two rotating parts 32 are located above the top plate 36 and are symmetrically arranged with the top plate 36 as the symmetry axis, so that the end of the reverse osmosis membrane 12 abuts against the top plate 36 when entering between the leather ring 33 and the fixed ring 34. The top plate 36 supports the end of the reverse osmosis membrane 12 and can keep the end of the reverse osmosis membrane 12 flat.

[0054] As a further description of the above-mentioned technology, a reverse osmosis membrane filter and its working method: one end of the two rotating parts 32 passes through the cylinder 11 and is connected to the belt 37 for transmission. The two top plates 36 are rotated synchronously by the belt 37, so that the various leather rings 33 move synchronously, ensuring that the conveying speed at various positions of the reverse osmosis membrane 12 is the same. The end of the cylinder 11 away from the liquid inlet pipe 15 is threadedly connected to a sealing cover 38, and the water outlet pipe 13 and the liquid outlet pipe 14 are both fixed on the sealing cover 38.

[0055] As a further description of the above-mentioned technology, a reverse osmosis membrane filter and its working method are provided: two sealing rings 39 are fixedly connected to the inner wall of the sealing cover 38. The diameters of the two sealing rings 39 are respectively the same as those of the cylinder 11 and the fixing ring 34. The function of the two sealing rings 39 is to seal the junction between the first cavity and the second cavity to prevent leakage of the solution.

[0056] As a further description of a reverse osmosis membrane filter and its working method of the above technology: the measuring mechanism 2 includes a semicircular baffle 21 fixedly connected to the top of the inner wall of the liquid outlet pipe 14, the baffle 21 blocks the top of the solution so that the solution can only impact the bottom of the impeller a22, thereby driving the impeller a22 to rotate, the inner rotation of the liquid outlet pipe 14 is connected to the impeller a22, one end of the impeller a22 passes through the liquid outlet pipe 14 and is fixedly connected to a turntable 23, the liquid outlet pipe 14 is fixedly connected to a side close to the turntable 23 with a horizontal frame 27, a pointer 28 is slidably connected to the horizontal frame 27, a counterweight slider 25 is slidably connected to the inner part of the turntable 23, a spring 24 is fixedly connected between the counterweight slider 25 and the turntable 23, a color block 26 is fixedly connected to the outer side of the counterweight slider 25, the counterweight slider 25 and the spring 24 are located in a straight line and do not coincide with the center point of the turntable 23, and the function is to rotate the turntable 23 to drive the counterweight slider 25 to do circular motion, so that the counterweight slider 25 is subjected to its own centrifugal force.

[0057] As a further description of the above technology, a reverse osmosis membrane filter and a working method thereof: A reverse osmosis membrane filter working method comprises the following steps:

[0058] S1: After the sealing cover 38 is rotated to open, the reverse osmosis membrane 12 that is clogged after long-term use in the cylinder 11 is pulled out, and then the sealing plate 31 is taken out from the strip groove at the top of the cylinder 11;

[0059] S2: Pass one end of the new reverse osmosis membrane 12 through the strip groove of the cylinder 11 until the end of the reverse osmosis membrane 12 enters between the leather ring 33 and the top plate 36. During this process, the reverse osmosis membrane 12 must be kept flat, and the edges on both sides of the reverse osmosis membrane 12 are located between the leather ring 33 and the fixed ring 34. Twist one of the top plates 36 to drive the other top plate 36 to rotate synchronously through the belt 37. At this time, the leather ring 33 circulates outside the two top plates 36 to transport the reverse osmosis membrane 12 to the inside of the cylinder 11 until the reverse osmosis membrane 12 surrounds the fixed ring 34.

[0060] S3: Install the sealing plate 31 and the sealing cover 38 back to their original positions, and connect the liquid inlet pipe 15 to the solution delivery pipe, and connect the liquid outlet pipe 14 and the water outlet pipe 13 to the solution output pipe and the external water storage system respectively;

[0061] S4: After the solution is transported to the inside of the cylinder 11 through the liquid inlet pipe 15, the thrust of the solution causes the impeller b42 to rotate, and the impeller b42 drives the water distribution plate 46 to swing back and forth through the crank a44, the transmission frame 43 and the crank b45 to disperse the solution, so that the solution is fully in contact with the reverse osmosis membrane 12, and the water filtered by the solution passes through the reverse osmosis membrane 12 and flows between the reverse osmosis membrane 12 and the cylinder 11, the solution that is not completely filtered flows out through the liquid outlet pipe 14, and the filtered water flows out through the water outlet pipe 13;

[0062] S5: The solution flowing out of the liquid outlet pipe 14 drives the impeller a22 to rotate, and then drives the counterweight slider 25 to make a circular motion through the turntable 23, so that the counterweight slider 25 slides under the action of centrifugal force. The position of the color block 26 on the counterweight slider 25 is observed to determine the flow rate of the solution in the liquid outlet pipe 14, and then reflect the filtering effect of the reverse osmosis membrane 12.

[0063] Working principle: When replacing the reverse osmosis membrane 12, first rotate the sealing cover 38 to open it, then pull out the reverse osmosis membrane 12 that has been blocked after long-term use in the cylinder 11, and take out the sealing plate 31 from the top strip groove of the cylinder 11, and pass one end of the new reverse osmosis membrane 12 through the strip groove of the cylinder 11 until the end of the reverse osmosis membrane 12 enters between the leather ring 33 and the top plate 36. The function of the top plate 36 is to support the end of the reverse osmosis membrane 12 so that the end of the reverse osmosis membrane 12 can remain flat when entering between the leather ring 33 and the fixed ring 34. At this time, the edges on both sides of the reverse osmosis membrane 12 are located between the leather ring 33 and the fixed ring 34, the purpose is to limit the position of the reverse osmosis membrane 12 and prevent it from entering the reverse osmosis membrane 12 during the transmission. When the reverse osmosis membrane 12 is delivered, the reverse osmosis membrane 12 is prevented from wrinkling and tilting, one of the top plates 36 is twisted to drive the other top plate 36 to rotate synchronously through the belt 37, so that the leather sleeve ring 33 is circulated outside the two top plates 36, and the reverse osmosis membrane 12 is gradually delivered to the inside of the cylinder 11 until the reverse osmosis membrane 12 surrounds the fixed ring 34. At this time, the reverse osmosis membrane 12 is cylindrical, the inside of the reverse osmosis membrane 12 is the first cavity, and the space between the reverse osmosis membrane 12 and the cylinder 11 is the second cavity. Finally, the sealing plate 31 and the sealing cover 38 are installed back to their original positions, and the liquid inlet pipe 15 is fixedly connected to the solution delivery pipeline, and the liquid outlet pipe 14 and the water outlet pipe 13 are fixedly connected to the solution output pipeline and the external water storage system respectively;

[0064] When filtering a solution, after the solution is transported to the inside of the cylinder 11 through the liquid inlet pipe 15, the thrust of the solution drives the impeller b42 to rotate, and the rotation of the impeller b42 drives the crank a44 to rotate. When the crank a44 rotates, the end away from the impeller b42 slides inside the transmission frame 43, causing the transmission frame 43 to swing back and forth. The swing of the transmission frame 43 drives the crank b45 and the water dividing plate 46 to swing back and forth to disperse the solution, so that the solute in the solution is evenly mixed with the water, which alleviates the barrier between the solute and the reverse osmosis membrane 1. 2, and driven by the swing of the reverse osmosis membrane 12, the solution inside the reverse osmosis membrane 12 will be spread out and fully contact with the reverse osmosis membrane 12, thereby expanding the contact area between the solution and the reverse osmosis membrane 12, thereby improving the filtration efficiency of the solution, and the water filtered by the solution passes through the reverse osmosis membrane 12 and flows into the second cavity between the reverse osmosis membrane 12 and the cylinder 11 and flows out through the water outlet pipe 13, and the solution that is not completely filtered is retained in the first cavity and finally flows out through the liquid outlet pipe 14;

[0065] When the solution passes through the liquid outlet pipe 14, it drives the impeller a22 to rotate. The rotation of the impeller a22 drives the turntable 23 to rotate. The turntable 23 drives the counterweight slider 25 and the color block 26 to make a circular motion. The circular motion of the color block 26 will form a circular trajectory on the turntable 23. At the same time, the counterweight slider 25 is pushed by the centrifugal force under the action of its own weight, so that it slides relative to the turntable 23. The counterweight slider 25 slides the color block 26 to move synchronously. The movement of the color block 26 changes the diameter of the circular trajectory. By observing the diameter of the circular trajectory, the rotation speed of the turntable 23 and the impeller a22 can be intuitively judged, which reflects the flow rate of the solution in the liquid outlet pipe 14. The worse the filtering effect of the reverse osmosis membrane 12 is, the more solution is retained in the first cavity, and the faster the flow rate of the solution in the liquid outlet pipe 14 is. Therefore, this design can reflect the filtering effect of the reverse osmosis membrane 12, and it is convenient to replace the reverse osmosis membrane 12 in time.

[0066] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a reverse osmosis membrane filter and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.

One end of the cylinder (11) away from the liquid inlet pipe (15) is threadedly connected to a sealing cover (38). The water outlet pipe (13) and the liquid outlet pipe (14) are both fixed on the sealing cover (38).

7. A reverse osmosis membrane filter according to claim 6, characterized in that: Two sealing rings (39) are fixedly connected to the inner wall of the sealing cover (38), and the diameters of the two sealing rings (39) are respectively the same as those of the cylinder (11) and the fixing ring (34).

8. A reverse osmosis membrane filter according to claim 1, characterized in that: The measuring mechanism (2) comprises a semicircular baffle (21) fixedly connected to the top of the inner wall of the liquid outlet pipe (14); the liquid outlet pipe (14) is rotatably connected to an impeller a (22); one end of the impeller a (22) penetrates the liquid outlet pipe (14) and is fixedly connected to a turntable (23); a side of the liquid outlet pipe (14) close to the turntable (23) is fixedly connected to a horizontal frame (27); a pointer (28) is slidably connected to the horizontal frame (27); a counterweight slider (25) is slidably connected to the inside of the turntable (23); a spring (24) is fixedly connected between the counterweight slider (25) and the turntable (23); a color block (26) is fixedly connected to the outside of the counterweight slider (25); the counterweight slider (25) and the spring (24) are located on a straight line and do not coincide with the center point of the turntable (23).

9. A reverse osmosis membrane filter operating method, applied to a reverse osmosis membrane filter according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1: After the sealing cover (38) is rotated to open, the reverse osmosis membrane (12) that has been clogged after long-term use in the cylinder (11) is extracted, and then the sealing plate (31) is taken out from the strip groove at the top of the cylinder (11); S2: Pass one end of the new reverse osmosis membrane (12) through the strip groove of the cylinder (11) until the end of the reverse osmosis membrane (12) enters between the leather ring (33) and the top plate (36). During this process, the reverse osmosis membrane (12) must be kept flat, and the edges on both sides of the reverse osmosis membrane (12) are located between the leather ring (33) and the fixed ring (34). Twist one of the top plates (36) to drive the other top plate (36) to rotate synchronously through the belt (37). At this time, the leather ring (33) circulates outside the two top plates (36) to transport the reverse osmosis membrane (12) to the inside of the cylinder (11) until the reverse osmosis membrane (12) surrounds the fixed ring (34) once; S3: Install the sealing plate (31) and the sealing cover (38) back to their original positions, and connect the liquid inlet pipe (15) to the solution delivery pipe, and connect the liquid outlet pipe (14) and the water outlet pipe (13) to the solution output pipe and the external water storage system respectively; S4: After the solution is transported to the inside of the cylinder (11) through the liquid inlet pipe (15), the thrust of the solution causes the impeller b (42) to rotate, and the impeller b (42) drives the water distribution plate (46) to swing back and forth through the crank a (44), the transmission frame (43) and the crank b (45) to disperse the solution, so that the solution is fully in contact with the reverse osmosis membrane (12), and the water filtered by the solution passes through the reverse osmosis membrane (12) and flows between the reverse osmosis membrane (12) and the cylinder (11), the solution that is not completely filtered flows out through the liquid outlet pipe (14), and the filtered water flows out through the water outlet pipe (13); S5: The solution flowing out of the liquid outlet pipe (14) drives the impeller a (22) to rotate, and then drives the counterweight slider (25) to make a circular motion through the turntable (23), so that the counterweight slider (25) slides under the action of centrifugal force. The flow rate of the solution in the liquid outlet pipe (14) is determined by observing the position of the color block (26) on the counterweight slider (25), and then the filtering effect of the reverse osmosis membrane (12) is reflected.
