Technical Field

[0001] This utility model relates to a liquid test filter that is easy to clean and replace the filter membrane. Background Technology

[0002] With the rapid development of industry and technology, membrane filtration technology is being used more and more widely in water treatment, medical, food and beverage industries. A variety of membranes with different materials and pore sizes have emerged on the market, including polypropylene, polytetrafluoroethylene, nylon, and glass fiber, each with its specific uses and effects. However, due to the wide variety of membranes, their performance in actual use, especially under different operating conditions, often lacks sufficient data and support. This necessitates the availability of equipment to effectively test and evaluate these membranes.

[0003] Frequent membrane replacement is indeed necessary when conducting filter membrane performance tests to evaluate the effectiveness of different types of membranes. However, most existing filter membrane testing devices have certain limitations in their design, especially during membrane replacement. These devices are typically complex in design, and membrane replacement is time-consuming and labor-intensive, which undoubtedly increases the difficulty and cost of the testing work, and also reduces the efficiency and frequency of testing.

[0020] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0021] like Figures 1-3As shown, this embodiment provides a liquid test filter that is easy to clean and replace the filter membrane. It includes a frame 1, in which filter cylinders 2 and collection cylinders 3 are arranged vertically. The filter cylinder 2 is divided into an upper cylinder body 4 and a lower cylinder body 5 that are detachably connected. The upper cylinder body 4 and the lower cylinder body 5 are connected by lifting eye bolts. A filter plate 6 is arranged between the upper cylinder body 4 and the lower cylinder body 5. A filter membrane 7 is arranged on the filter plate 6. Rotating shafts 8 are arranged on both sides of the collection cylinder 3. During use, the rotating shafts 8 are restricted from moving, and the position of the collection cylinder 3 remains fixed.

[0022] During the experiment, the liquid to be filtered was passed into the filter cylinder 2, and the liquid was filtered through the filter membrane 7 on the filter plate 6. The filtered liquid flowed into the collection cylinder 3, and then the filtered liquid was taken out from the collection cylinder 3 to check the filtration effect.

[0023] When the filter membrane 7 needs to be replaced, open the lifting eye bolts, move the upper cylinder 4 upwards to separate the upper cylinder 4 from the lower cylinder 5, and expose the filter plate 6. The filter plate 6 can be easily removed to replace the filter membrane 7 on the filter plate 6. After the filter membrane 7 is replaced, put the filter plate 6 back in its original position, move the upper cylinder 4 downwards, and fix it to the lower cylinder 5 again using the lifting eye bolts.

[0024] When it is necessary to clean the collection cylinder 3, the restriction on the rotating shaft 8 is released, allowing the collection cylinder 3 to rotate outward and the collection cylinder cover 17 to be opened normally for easy cleaning.

[0025] In this embodiment, support plates 9 are provided on both sides of the upper cylinder 4, and a lifting frame 10 is provided on the bottom surface of the support plate 9. A cylinder 11 is provided on the outer side of the lifting frame 10. When the filter membrane 7 needs to be replaced, the lifting eye bolts connecting the upper cylinder 4 and the lower cylinder 5 are opened, the piston rod of the cylinder 11 is pointing upward, and the piston rod of the cylinder 11 extends outward to move the lifting frame 10 upward, which at the same time drives the support plate 9 and the upper cylinder 4 to move upward, so that the upper cylinder 4 and the lower cylinder 5 are separated, thereby allowing the filter plate 6 to be pulled out for replacement of the filter membrane 7.

[0026] In this embodiment, a guide post 12 is inserted between the lifting frame 10 and the frame 1. The frame 1 is provided with a guide groove 13 that allows the guide post 12 to move up and down, so that the upper cylinder 4 does not deviate when it moves, thus ensuring the stability of the device.

[0027] In this embodiment, a filter cover 14 is provided on the upper cylinder 4, and a spare port 15 is provided on the filter cover 14. A liquid outlet 16 is provided on the lower cylinder 5. A collection cylinder cover 17 is provided on the upper part of the collection cylinder 3, and a liquid inlet 18 corresponding to the position of the liquid outlet 16 is provided on the collection cylinder cover 17. The liquid outlet 16 and the liquid inlet 18 are connected by a quick-connect fitting to ensure that the liquid can flow in smoothly. A discharge port 19 is provided on the lower part of the collection cylinder 3, and the filtered liquid is discharged through the discharge port 19.

[0028] In this embodiment, a vacuum port 20 is provided on one side of the liquid inlet 18. During the experiment, the collection cylinder 3 is gradually evacuated through the vacuum port 20, so that the liquid in the filter cylinder 2 can be smoothly filtered through the filter plate 6 and the filter membrane 7 and flow into the collection cylinder 3.

[0029] In this embodiment, a fixing frame 21 for mounting the rotating shaft 8 is provided on the frame 1 to fix the position of the rotating shaft 8 on the frame 1. The fixing frame 21 is provided with a threaded hole. In the test, the bolt is tightened in the threaded hole so that the rotating shaft 8 cannot rotate. When it is necessary to clean the collection cylinder 3, the bolt is loosened so that the rotating shaft 8 can drive the collection cylinder 3 to rotate, thereby opening the collection cylinder cover 17 for easy cleaning.

[0030] In this embodiment, the bottom of the frame 1 is provided with casters 22 to facilitate moving the device to different positions.

[0031] In summary, in this embodiment, the filter cylinder 2 is divided into an independently separable upper cylinder 4 and a lower cylinder 5, with the filter plate 6 containing the filter membrane 7 positioned between them. When the filter membrane 7 needs to be replaced, the operator only needs to use the cylinder 11 to lift the upper cylinder 4 and then remove the filter plate 6, greatly simplifying the replacement process. Furthermore, to address the issue of the collection cylinder cover 17 being unable to be opened due to the close proximity of the filter cylinder 2 and the collection cylinder 3, rotating shafts 8 are provided on both sides of the collection cylinder 3. When cleaning the collection cylinder 3 is required, the collection cylinder cover 17 can be easily opened by appropriately rotating the collection cylinder 3, greatly facilitating the cleaning process.

[0032] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
