Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane technology, and in particular to a reverse osmosis membrane testing device. Background Technology

[0002] A reverse osmosis membrane is an artificial semi-permeable membrane made to mimic a biological semi-permeable membrane. It is the core component of reverse osmosis technology. It uses pressure difference as the driving force to apply pressure to the feed liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will permeate in the opposite direction of natural osmosis. Thus, the permeated solvent, i.e., the permeate, is obtained on the low-pressure side of the membrane, while the concentrated solution, i.e., the concentrate, is obtained on the high-pressure side.

[0003] Before reverse osmosis membrane products leave the factory, it is necessary to conduct random inspections on the same batch of products to determine the pass rate of the batch, such as the reverse osmosis membrane testing device disclosed in the utility model patent with authorization announcement number CN222900729U.

[0004] While the above method can complete the testing of reverse osmosis membrane products, the tested reverse osmosis membrane products need to be removed before the installation of the next reverse osmosis membrane product can be carried out. This results in a long interval between two adjacent testing processes, and the testing efficiency still needs to be improved.

[0005] Therefore, it is necessary to invent a reverse osmosis membrane testing device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a reverse osmosis membrane testing device that allows the installation of a subsequent reverse osmosis membrane product during the testing of the previous one. After the testing of the previous reverse osmosis membrane product is completed, the output of the previous reverse osmosis membrane product from the testing station and the input of the subsequent reverse osmosis membrane product can be carried out simultaneously, thereby shortening the interval between adjacent tests and improving testing efficiency. This addresses the problem mentioned in the background art, where after the test is completed, the tested reverse osmosis membrane product needs to be removed before the installation of the next reverse osmosis membrane product can be carried out, resulting in a long interval between adjacent test processes and the need to improve testing efficiency.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a reverse osmosis membrane testing device, comprising:

[0008] A sealing water supply mechanism is used to seal and supply water to the test housing located at the test position;

[0009] A quick-change mechanism includes a support base fixedly mounted on the top of a base plate. Two side plates are fixedly mounted on the top of the support base. A rotating shaft is rotatably nested between the two side plates via bearings. A rotating block is fixedly sleeved on the outer side of the rotating shaft, and the left end of the rotating block abuts against the top of the support base.

[0010] Two sets of containment testing mechanisms are fixedly installed on the left side and top of the rotating block, respectively.

[0011] According to at least one embodiment of the reverse osmosis membrane testing apparatus of this disclosure, the sealed water supply mechanism includes a base plate, and each of the four corners of the top of the base plate is fixedly provided with a column.

[0012] According to at least one embodiment of the reverse osmosis membrane testing apparatus of this disclosure, a top plate is fixedly provided at the top of the four columns, and an electric push rod is fixedly provided at the center of the top of the top plate.

[0013] According to at least one embodiment of the reverse osmosis membrane testing apparatus of this disclosure, the output shaft of the electric push rod slides through the top plate and is fixedly connected to a sealing cover, and a water supply pipe is fixedly provided through the top right side of the sealing cover.

[0014] According to at least one embodiment of the reverse osmosis membrane testing apparatus of this disclosure, any group of the receiving testing mechanisms includes a fixed cylinder fixedly connected to the rotating block, a receiving cylinder fixedly sleeved on the top outer side of the fixed cylinder, and a plurality of rubber positioning strips uniformly fixedly arranged on the inner side of the receiving cylinder.

[0015] According to at least one embodiment of the reverse osmosis membrane testing device of this disclosure, a clean water pipe and a wastewater pipe are fixedly and sequentially disposed through the side of the fixed cylinder from top to bottom. A flow meter is disposed on both the clean water pipe and the wastewater pipe, and a sealing ring is fixedly nested at the top of the clean water pipe.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a quick-switching mechanism and two sets of testing and receiving mechanisms. This allows for the insertion of a new reverse osmosis membrane into the left receiving cylinder during testing of a reverse osmosis membrane product in the right receiving cylinder. After the testing of the reverse osmosis membrane product in the right receiving cylinder is completed, the left receiving cylinder is pushed, causing the rotating block to rotate clockwise around its axis. At this point, the left receiving cylinder rotates to a vertical testing position, while the right receiving cylinder simultaneously moves out of the testing position. Compared to existing technologies, this invention allows for the installation of a subsequent reverse osmosis membrane product during the testing of the previous one. After the testing of the previous reverse osmosis membrane product is completed, the output of the previous reverse osmosis membrane product from the testing position and the input of the subsequent reverse osmosis membrane product can be performed simultaneously, thus shortening the interval between tests on adjacent sides and improving testing efficiency.

These drawings are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] Figure 1 This is a schematic diagram of the overall structure of a reverse osmosis membrane testing apparatus according to one embodiment of the present disclosure.

[0028] Figure 2 This is a schematic diagram of the sealed water supply mechanism 1 of a reverse osmosis membrane testing apparatus according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the quick-switching mechanism 2 and the housing test mechanism 3 of a reverse osmosis membrane testing apparatus according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the reverse osmosis membrane testing device disclosed herein consists of three core modules: a sealed feed water mechanism 1, a quick switching mechanism 2, and two sets of test-accommodating mechanisms 3. The modules are mechanically connected to form a complete testing system. The two sets of test-accommodating mechanisms 3 respectively undertake the functions of "membrane installation under test" and "membrane testing under test". The two alternately enter the testing station, which greatly shortens the testing interval.

[0031] like Figure 2 As shown in this disclosure, the sealing water supply mechanism 1 includes a base plate 11 made of 304 stainless steel to ensure long-term load-bearing without deformation. Columns 12 are fixedly installed at the four corners of the top of the base plate 11, and a top plate 13 is fixedly installed at the top of the four columns 12. An electric push rod 14, preferably DTZ300, is fixedly installed at the center of the top of the top plate 13, with a rated thrust of 3000N and a stroke of 150mm. The output shaft of the electric push rod 14 slides through the top plate 13 and is fixedly connected to a sealing cover 15. A water supply pipe 16 is fixedly installed through the top right side of the sealing cover 15. The sealing cover 15 and the water supply pipe 16 face the testing station to ensure sealing performance and water supply stability during testing. After the sealing cover 15 is pressed down, the port of the water supply pipe 16 faces the inlet of the reverse osmosis membrane inside the receiving cylinder 32.

[0032] Therefore, once any container 32 arrives at the testing station, the electric push rod 14 drives the sealing cover 15 to move continuously downward, thereby sealing and pressing the sealing cover 15 onto the top of the container 32. Then, test water can be input into the container 32 through the water supply pipe 16. The test water eventually enters the reverse osmosis membrane product through the top water inlet end of the reverse osmosis membrane product.

[0033] like Figure 3 As shown, in a preferred embodiment, the quick switching mechanism 2 includes a support base 21 fixedly mounted on the top of the base plate 11. Two side plates 22 are fixedly mounted on the top of the support base 21. A rotating shaft 23 is rotatably nested between the two side plates 22 via a bearing. A rotating block 24 is fixedly sleeved on the outside of the rotating shaft 23. The left end of the rotating block 24 abuts against the top of the support base 21. The rotating block 24 is made of aluminum alloy to reduce its weight and facilitate adjustment.

[0034] Therefore, during the testing of reverse osmosis membrane products in the right-side receiving and testing mechanism 3, a new reverse osmosis membrane product can be placed into the left-side receiving cylinder 32. After the reverse osmosis membrane product inside the right-side receiving and testing mechanism 3 is tested, the left-side receiving cylinder 32 is pushed, thereby causing the rotating block 24 to rotate clockwise around the rotating shaft 23. At this time, the left-side receiving and testing mechanism 3 rotates to the vertical testing position, while the right-side receiving and testing mechanism 3 is simultaneously moved out of the testing position. Compared with the prior art, this utility model can install the next reverse osmosis membrane product during the testing of the previous reverse osmosis membrane product. After the testing of the previous reverse osmosis membrane product is completed, the output of the previous reverse osmosis membrane product from the testing position and the input of the next reverse osmosis membrane product can be carried out simultaneously, thereby shortening the interval between tests on adjacent sides and improving testing efficiency.

[0035] like Figure 3 As shown in this disclosure, any set of test-accommodating mechanisms 3 includes a fixed cylinder 31 fixedly connected to the rotating block 24. A receiving cylinder 32 is fixedly sleeved on the top of the outer side of the fixed cylinder 31. Multiple rubber positioning strips 33 are evenly fixedly arranged on the inner side of the receiving cylinder 32. A clean water pipe 34 and a sewage pipe 35 are fixedly and sequentially arranged through the side of the fixed cylinder 31 from top to bottom. A flow meter is installed on both the clean water pipe 34 and the sewage pipe 35. A sealing ring is fixedly nested at the top of the clean water pipe 34.

[0036] Therefore, after the reverse osmosis membrane product is placed inside the fixed cylinder 31, the four receiving cylinders 32 inside the fixed cylinder 31 position the reverse osmosis membrane product. At this time, the purified water output end at the lower end of the reverse osmosis membrane product is connected to the purified water pipe 34, and a seal is achieved by the sealing ring at the top of the purified water pipe 34. The wastewater output end at the lower end of the reverse osmosis membrane product is connected to the fixed cylinder 31. When the subsequent water supply pipe 16 supplies water to the inlet end of the reverse osmosis membrane product, the water flow is filtered by the reverse osmosis membrane product and then split into purified water and wastewater. The inlet water is discharged through the purified water pipe 34, and the wastewater is discharged through the wastewater pipe 35. During this process, the flow meters on the purified water pipe 34 and the wastewater pipe 35 measure the output water volume. Then, relevant testers judge whether the current reverse osmosis membrane product is qualified based on the measurement data.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
