Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration membrane testing technology, specifically to an ultrafiltration membrane testing platform. Background Technology

[0002] Ultrafiltration membranes are high-precision separation membranes with microporous structures, typically with pore sizes ranging from 0.001 to 0.1 micrometers (µm). They work by using pressure difference as the driving force and utilizing the micropores on the membrane surface for sieving and separation. You can think of it as an extremely fine sieve or filter screen that only allows water, minerals, and molecules smaller than the pore size (such as small organic molecules and ions) to pass through, while trapping suspended solids, colloids, bacteria, viruses, and large organic molecules in the water.

[0003] In water purification devices, ultrafiltration membrane testing is mostly done manually. In traditional technology, workers need to personally connect the ultrafiltration membrane to the water inlet. During testing, they need to use their arm strength to lift the ultrafiltration membrane against high water pressure. Traditional ultrafiltration membrane testing relies entirely on manual operation.

[0004] Testers must manually install the ultrafiltration membrane onto the high-pressure water injection port and continuously lift the membrane element with their arms during the test to resist the reaction force generated by the test water pressure. The weight lifted at one time can reach 5-15 kg, which is labor-intensive and can easily lead to muscle fatigue and repetitive strain injuries, causing occupational health problems. In addition, under high-pressure testing conditions, if the ultrafiltration membrane slips due to unstable grip, the high-pressure water may spray out, causing equipment damage and personal injury. Due to the limitations of manual operation intensity and safety, the number of tests that can be completed per day is limited, and the overall testing efficiency is low. Therefore, we need to propose an ultrafiltration membrane testing platform. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model features an inclined material guide tray design: the ultrafiltration membrane is stored in the inclined material guide tray, and the ultrafiltration membrane is automatically and orderly rolled downward by gravity, providing a basis for continuous feeding.

[0015] Automatic feeding mechanism: In conjunction with the material guide tray, it realizes automatic gripping, positioning and transfer of ultrafiltration membrane, completely replacing manual handling and lifting, and significantly reducing labor intensity;

[0016] Automatic clamping and spraying mechanism: This mechanism includes a movable spraying component with a tapered support tube head at its front end.

Subsequently, the test liquid is introduced into the ultrafiltration membrane through the spraying conduit, and the permeation performance or integrity test is carried out under controlled conditions.

[0017] This integrated system automates the entire process from feeding, clamping, and testing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: an ultrafiltration membrane testing platform, including a box 1, with inclined material guide shells 2 fixed on one side of the box 1;

[0025] In use, an ultrafiltration membrane 3 is placed inside the feed tray 2. The ultrafiltration membranes 3 are arranged in sequence. An automatic clamping and spraying mechanism for clamping and spraying detection of ultrafiltration membranes 3 is provided on both sides of the upper end of the box 1. The automatic clamping and spraying mechanism includes a movable spraying component and a fixed support component. An automatic feeding mechanism for lifting and feeding ultrafiltration membranes 3 is provided at the lower end of the box 1.

[0026] During feeding, the automatic feeding mechanism includes a second electric cylinder 9 installed at the bottom of the box 1. The second electric cylinder 9 is connected to a corresponding controller, and the second electric cylinder 9 is controlled by the corresponding controller. The piston rod end of the second electric cylinder 9 slides through the box 1. A U-shaped support frame 10 is fixed to the piston rod end of the second electric cylinder 9. Positioning grooves 11 for positioning the ultrafiltration membrane 3 are opened on both sides of the U-shaped support frame 10.

[0027] One side of the U-shaped support frame 10 is in contact with one side of the guide support shell 2. The positioning groove 11 adopts a triangular groove structure. In use, the piston rod end is driven down by the second electric cylinder 9, which can drive the U-shaped support frame 10 to move downward. At this time, the ultrafiltration membrane 3 at the bottom rolls into the inner side of the positioning groove 11 for positioning, which is convenient for feeding. At this time, the second electric cylinder 9 drives the piston rod end to rise, which can drive the U-shaped support frame 10 to rise and move, aligning one end opening of the ultrafiltration membrane 3 with the conical support tube head 5 and the other end opening with the conical support head 8.

[0028] Specifically, the mobile spraying assembly includes a spraying conduit 4 that slides through one side of the housing 1. One end of the spraying conduit 4 is integrally formed with a tapered support head 5, and the other end of the spraying conduit 4 is provided with a linear drive device.

[0029] The linear drive device includes a mounting plate 6 fixed to the surface of the other end of the spray conduit 4 and a first electric cylinder 7 mounted on the surface of the mounting plate 6. The first electric cylinder 7 is connected to a corresponding controller, which controls the first electric cylinder 7. The piston rod end of the first electric cylinder 7 slides through the mounting plate 6 and is fixed to the surface of the housing 1. The fixed support assembly includes a support rod fixed to the inner end of the other side of the housing 1. The surface of the support rod is provided with a tapered support head 8, which is correspondingly arranged with the tapered support tube head 5.

[0030] The piston rod end is retracted by the first electric cylinder 7, and the mounting plate 6 is moved towards the conical support head 8 by the cylinder end of the first electric cylinder 7. The conical support tube head 5 of the liquid spraying conduit 4 can be inserted along one end opening of the ultrafiltration membrane 3 and the ultrafiltration membrane 3 can be squeezed and moved. The other end opening of the ultrafiltration membrane 3 is squeezed and fixed on the surface of the conical support head 8. The clamping is convenient and applicable to the clamping of ultrafiltration membranes 3 of different sizes in conventional applications. A sealing layer is provided on the surface of both the conical support tube head 5 and the conical support head 8. The sealing layer can be made of rubber to increase the sealing performance during the squeezing installation.

[0031] The liquid spraying conduit 4 is connected to the liquid source and is transported by the existing delivery pump. During testing, the liquid source is introduced into the inner side of the ultrafiltration membrane 3 through the liquid spraying conduit 4 and the conical support tube head 5. After the liquid source is filtered by the ultrafiltration membrane 3, it is discharged. The seepage situation of the ultrafiltration membrane 3 when filtering the liquid source is observed according to the pressure when the liquid source is introduced.

[0032] When feeding, the liquid source is turned off, and the first electric cylinder 7 drives the piston rod end to extend. The cylinder end of the first electric cylinder 7 can drive the mounting plate 6 to reset, which can drive the conical support tube head 5 to separate from the ultrafiltration membrane 3. At this time, the ultrafiltration membrane 3 after testing can be taken out. It is convenient to take out and improves the testing efficiency.

[0033] Then repeat the above test procedure to test the next ultrafiltration membrane 3. It is easy to use, with automated feeding and testing, high efficiency, and no need for manual lifting, making the test safer.

[0034] A water-proof boss 100 is provided on the inner side of the housing 1. The piston rod end of the second electric cylinder 9 passes through the water-proof boss 100. The water-proof boss 100 is used to isolate the liquid flowing out after filtration, and will not leak along the gap at the connection of the piston rod end of the second electric cylinder 9. A discharge pipe 12 for discharging test liquid is provided at the bottom of the housing 1. The liquid flowing out after filtration is discharged through the discharge pipe 12, and an electric control valve can be installed on the discharge pipe 12 to control the opening and closing of the discharge pipe 12.
