Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membranes, and specifically relates to a reverse osmosis membrane testing device. Background Technique

[0002] A reverse osmosis membrane is an artificial semi-permeable membrane with certain characteristics made by simulating a biological semi-permeable membrane, and is the core component of reverse osmosis technology. The principle of reverse osmosis technology is that under the action of a pressure higher than the osmotic pressure of the solution, these substances and water are separated based on the fact that other substances cannot pass through the semi-permeable membrane. The membrane pore diameter of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic substances, etc. in water. Before the reverse osmosis membrane leaves the factory, it needs to be tested to determine the internal permeability.

[0003] However, the existing testing device has a single structure and can only judge whether it is blocked inside by the flowing water, and it is impossible to know the specific blocked area inside. Moreover, the installation of the reverse osmosis membrane is relatively troublesome during the test, which is not convenient for the testing work. Therefore, we propose a reverse osmosis membrane testing device to solve the problems mentioned above. Content of the Utility Model

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: a reverse osmosis membrane testing device, including a test bench 1, a placement groove 2, a first elastic sheet 3, a sewage outlet 4, a water purification pipe 5, a gasket 6, a water purification tank 7, a sewage tank 8, a partition board 9, a valve 10, a water storage tank 11, a water pump 12, a water delivery pipe 13, an extrusion cover 14, a water inlet groove 15, a water outlet 16, a threaded rod 17, a fixed platform 18 and a hydraulic cylinder 19. A placement groove 2 is arranged in the test bench 1, and a first elastic sheet 3 is arranged in the placement groove 2. A sewage outlet 4 is arranged at the bottom of the placement groove 2. A water purification pipe 5 is arranged in the sewage outlet 4. A gasket 6 is arranged at the top of the water purification pipe 5. The bottom of the gasket 6 is connected to a water purification tank 7. A sewage tank 8 is arranged at the bottom of the sewage outlet 4. A partition board 9 is arranged in the sewage tank 8 and the water purification tank 7. Valves 10 are arranged at the bottoms of the sewage tank 8 and the water purification tank 7. A water storage tank 11 is arranged at the bottom of the sewage tank 8. A water pump 12 is arranged in the water storage tank 11. The top of the water pump 12 is connected to a water delivery pipe 13. The water delivery pipe 13 is connected to an extrusion cover 14 through a pipeline. A water inlet groove 15 is arranged in the extrusion cover 14. A water outlet 16 is arranged at the bottom of the water inlet groove 15. A threaded rod 17 is connected to the extrusion cover 14. A fixed platform 18 is connected to the threaded rod 17. A hydraulic cylinder 19 is connected to the rear side of the fixed platform 18.

[0020] The first elastic sheets 3 are arranged in the placement groove 2 at equal intervals, so as to stabilize the reverse osmosis membrane through the first elastic sheets 3. The water purification pipe 5 is arranged at the central position of the placement groove 2. A gasket 6 is arranged around the top of the water purification pipe 5. Spring sheets are arranged inside the gasket 6. Through the gasket 6, the water purification pipe 5 is tightly attached to the internal filter pipe of the reverse osmosis membrane, preventing the filtered sewage from leaking from the connection between the water purification pipe 5 and the internal part of the reverse osmosis membrane.

[0021] A partition plate 9 is provided in both the purified water tank 7 and the sewage tank 8 to separate them, facilitating separate treatment of multiple groups. Valves 10 are provided at the bottoms of both the purified water tank 7 and the sewage tank 8, facilitating the recycling of wastewater after the test. The valves 10 are controlled by motors, and inclined sampling ports are provided on the outsides of both the purified water tank 7 and the sewage tank 8.

[0022] The sewage discharge port 4, the purified water pipe 5, the gasket 6, the purified water tank 7, the sewage tank 8, the partition plate 9, the valve 10, the water storage tank 11, the water pump 12, the water delivery pipe 13, the extrusion cover 14, the water inlet groove 15, and the water outlet 16 form a water circulation structure. A filter element is provided in the water storage tank 11 to filter impurities in the water discharged from the sewage tank 8. Flow meters are connected to the bottoms of the sewage discharge port 4 and the purified water pipe 5 to determine the degree of blockage by the flow rate.

[0023] The threaded rod 17 is connected to the extrusion cover 14 through a rotating shaft, and a limiting rod is connected to the extrusion cover 14. Thus, the rotation of the threaded rod 17 drives the extrusion cover 14 to move. The threaded rod 17 is threadedly connected to the fixed platform 18, enabling the threaded rod 17 to move up and down on the fixed platform 18 when it rotates.

[0024] The fixed platform 18 forms a movable structure on the test bench 1 through the hydraulic cylinder 19, thereby changing the height of the entire fixed platform 18 to change the position of the extrusion cover 14.

[0025] Working principle: When using this reverse osmosis membrane testing device, first, place the reverse osmosis membrane into the placement groove 2 of the test bench 1, such that the filter pipe inside the reverse osmosis membrane is inserted into the purified water pipe 5 of the placement groove 2. After insertion, the spring pieces inside the gasket 6 at the top of the purified water pipe 5 contract, and then the gasket 6 is pressed between the purified water pipe 5 and the filter pipe through the reaction force, achieving a sealing effect. At the same time, the first elastic piece 3 of the placement groove 2 also contracts, and then fixes the reverse osmosis membrane through the reaction force, enabling the reverse osmosis membrane to be stably placed in the placement groove 2. Then, start the hydraulic cylinder 19, causing the fixed platform 18 and the extrusion cover 14 on the fixed platform 18 to move downward following the contraction of the hydraulic cylinder 19 until the extrusion cover 14 touches the top of the reverse osmosis membrane. Then, rotate the threaded rod 17 on the fixed platform 18 respectively, causing the threaded rod 17 to drive the extrusion cover 14 to move downward, thereby performing the extrusion and fixing work on the reverse osmosis membrane.

[0026] Then start the water pump 12 in the water storage tank 11, so that the water pump 12 inputs the test water in the water storage tank 11 into the water inlet groove 15 of the extrusion cover 14 through the water delivery pipe 13, and then discharges it from the water outlet 16 at the bottom of the water inlet groove 15 into the reverse osmosis membrane, and then starts the test. The water flow will be discharged from the sewage outlet 4 and the clean water pipe 5 respectively, and then enter the clean water bin 7 and the sewage bin 8. The flow meters at the bottoms of the sewage outlet 4 and the clean water pipe 5 will record the flow information of the test water at the outlets of the two drain pipes for subsequent analysis. At the same time, samples can be taken from the sampling ports on the outer sides of the clean water bin 7 and the sewage bin 8 for comparison. Finally, after the test is completed, open the valves 10 at the bottoms of the clean water bin 7 and the sewage bin 8, so that the test water passes through the filter at the bottom outlet to filter out impurities and then enters the water storage tank 11 again for reuse. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
