Description

Technical Field

[0001] This utility model relates to the field of hollow fiber membrane flux testing technology, specifically to a hollow fiber membrane flux testing device. Background Technology

[0002] In industrial production and scientific research, hollow fiber membranes are widely used in key scenarios such as water treatment, biological separation, and gas separation due to their superior filtration performance, high selectivity, compact space utilization, and low cost. Membrane flux, as a core indicator of filtration performance, directly affects the amount of wastewater treated and the cost during the production cycle; higher flux means more wastewater is treated per unit time, significantly improving production efficiency and drastically reducing costs. Therefore, timely and accurate membrane flux testing is crucial for ensuring product performance, both in the research and development of hollow fiber membranes and in actual production applications.

[0003] However, most current hollow fiber membrane flux testing devices only support flux testing of a single membrane filament, failing to meet the need for simultaneous testing of multiple filaments. In large-scale production scenarios, companies need to conduct flux tests on hundreds or even thousands of membrane filaments to ensure stable product quality. Single-filament testing is not only time-consuming but also requires significant manpower, resulting in low testing efficiency.

[0004] Therefore, there is an urgent need for a hollow fiber membrane flux testing device that can simultaneously test multiple membrane filaments, in order to solve the problem of low testing efficiency in the current hollow fiber membrane flux testing devices. Utility Model Content

The outer side of the piston 28 is slidably connected to the inner sidewall of the outer tube 26. The other end of the outer tube 26 is provided with a limiting point 29 that cooperates with the piston 28. The other end of the extension tube 27 is fixedly connected to one end of the pneumatic quick-connect plug 23.

[0043] By setting up a telescopic tube 22 and configuring it as an outer sleeve 26, an extension tube 27, and a piston 28, the length of the telescopic tube 22 can be adjusted as needed, thus solving the problems of fixed installation position and poor adaptability of hollow fiber membrane filaments.

[0045] To facilitate the installation of test component 11, this embodiment is an improvement upon the above embodiment. The difference lies in that the housing component 10 includes a base plate 31, a first L-shaped plate 32, and a second L-shaped plate 33.

[0050] To facilitate testing under different pressures, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the top of the liquid storage tank 13 is provided with an air inlet 39 and an air outlet 40, and an air inlet valve 41 is provided on the second L-shaped plate 33. One end of the air inlet valve 41 passes through the second L-shaped plate 33 and is fixedly connected to the second L-shaped plate 33. The end of the air inlet valve 41 that passes through the second L-shaped plate 33 is connected to the air inlet 39 through a pipe. A gas venting valve 42 is provided on the top of the liquid storage tank 13.

[0051] The air inlet valve 41 can be connected to an external air source. The gas from the air source can pass through the air inlet valve 41 and then enter the liquid storage tank 13 through the air inlet 39, thereby increasing the pressure inside the liquid storage tank 13 and thus increasing the pressure of the liquid entering the test structure 14. The air outlet 40 and the gas venting valve 42 are designed to facilitate the discharge of gas from the liquid storage tank 13, thereby reducing the pressure inside the liquid storage tank 13 and thus reducing the pressure of the liquid entering the test structure 14.

[0052] To facilitate the replenishment of liquid and the discharge of liquid from the storage tank 13, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the top of the storage tank 13 is provided with a liquid inlet 43 and the bottom of the storage tank 13 is provided with a liquid venting valve 44.

[0053] The liquid inlet 43 can be connected to an external liquid source, and the liquid source liquid can enter the liquid storage tank 13 through the liquid inlet 43; the liquid vent valve 44 can be connected to an external liquid discharge device, and the liquid in the liquid storage tank 13 can be discharged through the liquid vent valve 44.

[0054] To facilitate the detection of the liquid level and temperature in the storage tank 13, this embodiment is an improvement on the above embodiment.

The liquid level and temperature gauge 45 is set in conjunction with the storage tank 13 to display the liquid level and temperature in the storage tank 13.

[0055] The liquid level and temperature gauge 45 is provided to facilitate the detection of the liquid level and temperature inside the storage tank 13. The liquid level and temperature gauge 45 is connected to the inside of the storage tank 13. The liquid level and temperature gauge 45 can be any existing liquid level and temperature gauge that can achieve the functions of this utility model.

[0056] As a further preferred embodiment, the liquid level and temperature gauge 45 is electrically connected to the control console 12. It should be noted that this connection method is existing technology and will not be described in detail. By electrically connecting the liquid level and temperature gauge 45 to the control console 12, the liquid level and temperature data in the storage tank 13 can be easily transmitted to the control console 12 for display, facilitating observation and operation.

[0057] Working principle of this utility model:

[0058] When testing multiple hollow fiber membranes, simply install the membranes onto the adjustable plugs 20 in different test structures 14. Then, control the solenoid valves 16 and metering pumps 18 in the corresponding test structures 14 via the control console 12. This allows the liquid in the storage tank 13 to pass through the flow meter 17, metering pump 18, pressure sensor 19, and adjustable plugs 20, thus entering the hollow fiber membrane under test. Detecting the liquid flow rate using the flow meter 17 and metering pump 18 provides the data basis for subsequent flux calculations.
