Description

Technical Field

[0001] The utility model relates to the technical field of pure water flux testing devices, in particular to a tubular ceramic membrane pure water flux testing device. Background Art

[0002] Ceramic membranes have the advantages of high mechanical strength, high temperature resistance and good stability. They are a new type of separation material that is efficient, energy-saving and environmentally friendly. They are used in many fields such as medicine, food, fine chemicals and water treatment.

[0003] Ceramic membrane separation technology is a material separation technology based on the screening effect of porous ceramic media. That is, under pressure, the raw liquid flows inside or outside the membrane, small molecular substances (liquids) pass through the microporous membrane in the direction perpendicular to it, and large molecular substances (or solid particles) are retained by the membrane, thereby achieving the purpose of separation, concentration and purification. In order to understand the separation performance of ceramic membranes, it is very important to test the pure water flux of the membrane. However, when the existing testing device measures the pure water flux of the overall tubular ceramic membrane element, the tubular ceramic membrane element is prone to swing under the action of water pressure, making it difficult to maintain the same porosity between individual tubular ceramic membrane elements, thereby reducing the accuracy of the pure water flux test results of the tubular ceramic membrane, causing certain inconveniences to the testing work.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, a tubular ceramic membrane pure water flux test device includes a test tank 1, which is made of organic glass. A fixed flange is provided on the top of the test tank 1. The test tank 1 is used to store sewage to ensure the smooth progress of subsequent pure water flux testing.

[0023] It also includes a first magnetic ring plate 2 arranged around the inner wall of the test tank 1 and a limit assembly provided on the test tank 1, wherein the limit assembly includes an adapter 4 matching the inner diameter of the test tank 1, a confluence groove 5 opened inside the adapter 4, a plurality of groups of spaced-apart diverter seats 6 arranged at the bottom of the adapter 4, and the diverter seats 6 are connected to the confluence groove 5, an outlet pipe 7 arranged at the top of the adapter 4 and connected to the confluence groove 5, a rubber sleeve 8 sleeved inside the diverter seat 6, the rubber sleeve 8 is a hard rubber tube body, and one end of the rubber sleeve 8 is connected to the diverter seat 6 by hot melt adhesive, and a tubular ceramic membrane monomer sleeved inside the rubber sleeve 8 9. The tubular ceramic membrane monomer 9 is a loess-fly ash-based ceramic membrane with a hollow interior and openings at both ends. A sealing rubber sleeve 10 is sleeved on the bottom end of the tubular ceramic membrane monomer 9. The sealing rubber sleeve 10 is a soft rubber sleeve with one end sealed. The other end of the rubber sleeve 8 and the open end of the sealing rubber sleeve 10 are respectively adhered to the two ends of the tubular ceramic membrane monomer 9 by hot melt adhesive. A limiting plate 11 is provided on the outside of the sealing rubber sleeve 10 to form a fixed limit plate for the tubular ceramic membrane monomer 9. Two sets of telescopic rods 12 are provided at the bottom of the limiting plate 11. A second magnetic ring plate 13 is provided at the bottom end of the telescopic rod 12 to match the first magnetic ring plate 2.

[0024] When the device is in use, the sealing rubber sleeve 10 is first sleeved on the bottom end of the tubular ceramic membrane monomer 9, and then the limit plates 11 of different specifications can be selected according to the porosity requirements between the tubular ceramic membrane monomers 9 during the test, so as to fix the bottom end of the tubular ceramic membrane monomer 9, thereby ensuring that the distance between the tubular ceramic membrane monomers 9 will not change during the test. After the bottom end of the tubular ceramic membrane monomer 9 is fixed, a matching rubber sleeve 8 is selected to form a seal on the top end of the tubular ceramic membrane monomer 9, so that water can only penetrate into the internal hollow area through the outer wall of the tubular ceramic membrane monomer 9, thereby entering the confluence tank 5. In the process of assembling the tubular ceramic membrane monomer 9 and placing it in the test tank 1, the first magnetic ring plate 2 set in the test tank 1 forms an adsorption on the second magnetic ring plate 13, thereby fixing the limit plate 11, further ensuring the tubular ceramic The stability of the membrane monomer 9 is achieved through the telescopic support formed by the telescopic rod 12 on the second magnetic ring plate 13, which allows the second magnetic ring plate 13 to have a certain range of movement. When it is magnetically fixed to the first magnetic ring plate 2, a certain error can be allowed. The outlet pipe 7 is connected to the main pipe outlet of the tee pipe, and any end of the tee pipe branch is connected to the vacuum pump through a silicone tube, and the other end is connected to the backwash water pump. It is only necessary to completely immerse the tubular ceramic membrane monomer 9 in the sewage to be treated and open the vacuum pump and the three-way valve connected to it, and close the backwash valve to start the operation of the tubular ceramic membrane monomer 9. The working principle of the tubular ceramic membrane monomer 9 is a central negative pressure filtration type. The sewage enters the inside of the membrane tube through the filtration action of the ceramic membrane, and then the negative pressure of the vacuum pump causes the water in the many ceramic membrane tubes to gather in the collecting trough 5, and then it is discharged from the outlet pipe 7. The pure water flux test of the tubular ceramic membrane monomer 9 is thus carried out.

[0025] In this embodiment, specifically, a sealing flange 3 matching the fixed flange is arranged around the outer periphery of the adapter 4, and the fixed flange and the sealing flange 3 are fixed by bolts and nuts. When testing, the test tank 1 can be sealed by the fixation between the fixed flange and the sealing flange 3, and a sealing gasket can be arranged on the contact end surfaces of the two to improve the sealing between the two.

[0026] In this embodiment, specifically, an exhaust valve 14 is provided on the outside of the test tank 1. When the device completes the test, the staff can open the exhaust valve 14 to allow external gas to enter the interior of the test tank 1, thereby ensuring that the internal atmospheric pressure of the test tank 1 is equal to that of the outside, making it convenient to remove the limit assembly together with the tubular ceramic membrane unit 9 from the test tank 1.

[0027] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
