[0020] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0021] like Figs. 1-2 As shown, a detection device for a UF ultrafiltration membrane module includes: Frame 1, a limiting device is provided on frame 1, the limiting device is used to connect the UF ultrafiltration membrane module to be tested, the limiting device includes an inlet end and an outlet end, and an inlet flow meter 3 and an outlet flow meter 4 are respectively provided on the inlet end and the outlet end. A pressure sensor is installed on the limit device to monitor the pressure difference between the inlet and outlet ends. Water pump 5, the outlet of water pump 5 is connected to the inlet end; Control system 2 is electrically connected to inlet flow meter 3, outlet flow meter 4, pressure sensor and water pump 5.

[0022] Specifically, various devices are installed through frame 1. The UF ultrafiltration membrane module to be tested and the water pump 5 are connected to form a water circuit through a limiting device. The inlet flow meter 3 and the outlet flow meter 4 monitor the flow rate at the inlet and outlet ends, and their cooperation can confirm whether leakage has occurred. The pressure sensor measures the pressure difference between the inlet and outlet ends to confirm the influence of the UF ultrafiltration membrane module on the water pressure.

[0023] Furthermore, the limiting device includes a connecting seat and a connecting pipe. The connecting seat is connected to the end of the UF ultrafiltration membrane module, and the connecting pipe is connected to the inlet or outlet of the UF ultrafiltration membrane module. The inlet end is connected to the inlet of the UF ultrafiltration membrane module, and the outlet end is connected to the outlet of the UF ultrafiltration membrane module.

[0024] In this embodiment, a water storage tank 6 is also included, and the inlet and outlet of the water pump 5 are connected to the water storage tank 6.

[0025] Specifically, the water storage tank 6, water pump 5, and the UF ultrafiltration membrane module to be tested constitute the circulating water circuit.

[0026] Specifically, the water storage tank 6 is independently set up and equipped with a liquid level sensor and a water quality monitor. The water pump 5 is connected to the water storage tank 6 via a pump, or a valve is installed at the lower end of the water storage tank 6 connecting it to the water pump 5. In addition to routinely monitoring the flux and integrity of the UF ultrafiltration membrane module, it can also monitor the filtration capacity. During use, the water storage tank 6 is filled with a certain amount of water to be filtered. After testing, the water quality of the filtered water in the water storage tank 6 is measured. Because the water storage tank 6 is set up independently, one UF ultrafiltration membrane module can correspond to one water storage tank. The filtration effect of the UF ultrafiltration membrane module is confirmed by the changes in the water quality within the water storage tank 6, and the need for continuous filling with unfiltered water for testing is avoided, which could render the UF ultrafiltration membrane module unusable after testing.

[0027] In this embodiment, the limiting device is arranged vertically, with the water inlet located below the water outlet.

[0028] Specifically, ensure that the UF ultrafiltration membrane module is in full contact with the water flow.

[0030] Specifically, the connectors prevent the UF ultrafiltration membrane module from being stressed only at the outlet and inlet ends, thus improving stability during the testing process.

[0031] In this embodiment, the control system 2 is a desktop structure.

[0032] In this embodiment, the control system 2 is located on the side of the frame 1 away from the UF ultrafiltration membrane assembly.

[0033] Specifically, to prevent water leakage and contamination of the control system during installation and disassembly.

[0034] In this embodiment, the control system 2 includes a display screen, a power button, and a control button, which is used to control the water pump 5.

[0035] Specifically, the display screen shows various parameters in real time, including the real-time flow rate at the inlet, the real-time flow rate at the outlet, and the pressure difference between the inlet and outlet.

[0036] In this embodiment, frame 1 is an aluminum alloy frame 1.

[0037] In this embodiment, the water storage tank 6 is equipped with a liquid level alarm.

[0038] Specifically, the water level in the storage tank 6 is monitored in real time to prevent the water pump 5 from running dry.

[0039] In this embodiment, pump 5 is a booster pump.

[0040] Specifically, the booster pump ensures appropriate water pressure.

[0041] This embodiment describes a testing device for UF ultrafiltration membrane modules. Taking the testing of UF ultrafiltration membrane modules as an example: Install the UF ultrafiltration membrane module to be tested onto the limit device, start the water pump 5 through the control system 2, and observe the display screen. When the values ​​of the inlet flow meter 3 and the outlet flow meter 4 reach the preset values ​​and stabilize, it is in normal working condition. Then you can start adjusting the water pump 5 to test different water flows and pressures.

[0042] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
