Description

Technical Field

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

[0002] With the increasing severity of water scarcity and pollution, water treatment membrane technologies such as ultrafiltration and reverse osmosis membranes are widely used in municipal water supply, industrial wastewater treatment, and seawater desalination due to their advantages of high efficiency in removing pollutants and high separation efficiency. The performance parameters of water treatment membranes, such as filtration flux, retention rate, and fouling resistance, directly determine the operating efficiency and cost of the water treatment system. Therefore, before membrane product development, production quality inspection, and engineering application, their performance must be accurately evaluated using professional testing equipment.

[0003] Existing water treatment membrane testing methods often involve manually disassembling and replacing membrane modules to conduct multiple tests. This is not only time-consuming and labor-intensive, but also prone to inaccurate membrane module installation due to human error, which can damage the sealing environment or change the fluid flow direction, affecting the consistency of test data.

A sewage tank is fixedly installed on the top of one end of the base plate, and a wastewater tank is fixedly installed on the top of the other end. A testing mechanism connected to the sewage tank and the wastewater tank is installed on the top of the base plate. A switching mechanism for switching the position of the membrane module is installed on the top of the base plate.

[0005] The testing mechanism includes a water pump, an inlet pipe, a sealing plate, a flow meter, an electric cylinder, a connecting seat, and an outlet pipe. The sealing plate is fixedly installed on the side of the wastewater tank. One end of the inlet pipe is connected to the outlet on the lower side of the wastewater tank, and the other end is connected to the inlet on the top of the sealing plate. Two electric cylinders are provided, and the two electric cylinders are fixedly installed in the middle of the top of the base plate.

[0006] The switching mechanism includes a positioning plate, positioning holes, support holes, a support plate, a column, and an electric push rod. The column is rotatably installed in the middle of the top of the base plate. A fan-shaped positioning plate is fixedly installed on the upper side of the column. Two positioning holes are opened on the top of the positioning plate. A fan-shaped support plate is fixedly installed on the lower side of the column.

The motor 83 is fixedly installed in the middle of the top of the sewage tank 3. The motor 83 is electrically connected to the control module 2. The stirring mechanism 8 can stir the sewage in the sewage tank 3 to prevent the sewage from settling or stratifying, so that its concentration remains stable and the accuracy of the test is improved. The top of the sewage tank 3 is fixedly installed with a feed hopper 9, which is connected to the inside of the sewage tank 3. The feed hopper allows the pre-mixed sewage to be easily added into the sewage tank. The top of the bottom plate 1 is equipped with a switching mechanism 7 for switching the position of the membrane module 5.

[0022] The testing mechanism 6 includes a water pump 61, an inlet pipe 62, a sealing plate 63, a flow meter 64, an electric cylinder 65, a connecting seat 66, and an outlet pipe 67. The sealing plate 63 is fixedly installed on the side of the sewage tank 3. One end of the inlet pipe 62 is connected to the outlet on the lower side of the sewage tank 3, and the other end is connected to the inlet on the top of the sealing plate 63. Two electric cylinders 65 are provided, and the two electric cylinders 65 are fixedly installed in the middle of the top of the base plate 1. The telescopic ends of the electric cylinders 65 are fixedly connected to the bottom of both ends of the connecting seat 66. The middle of the top of the connecting seat 66 is provided with a groove that matches the outlet of the membrane module 5. The bottom of the sealing plate 63 and the groove on the top of the connecting seat 66 are both fixedly installed in the groove. A rubber ring 12 is installed, which is matched with the inlet and outlet of the membrane module 5. The rubber ring 12 is matched with the inlet and outlet of the membrane module 5, and the electric cylinder 65 drives the connecting seat 66 to press upward, which can seal the connection between the sealing plate 63 and the connecting seat 66 and the membrane module 5 to prevent sewage leakage during the test.

[0023] The switching mechanism 7 includes a positioning plate 71, positioning holes 72, support holes 73, a support plate 74, a column 75, and an electric push rod 76. The column 75 is rotatably mounted on the middle of the top of the base plate 1. A fan-shaped positioning plate 71 is fixedly mounted on the side of the upper end of the column 75. Two positioning holes 72 are opened on the top of the positioning plate 71. A fan-shaped support plate 74 is fixedly mounted on the side of the lower end of the column 75.

This allows for continuous testing of the membrane module 5, reducing manual intervention and improving testing efficiency. The positioning hole 72 of the positioning plate 71 and the support hole 73 of the support plate 74 form a double positioning system, ensuring that after each installation, the inlet and outlet of the membrane module 5 can be accurately aligned with the interface between the sealing plate 63 and the connecting seat 66. This avoids poor sealing or changes in fluid flow direction due to installation deviations, ensures consistent initial conditions for multiple tests, and reduces data errors.

[0024] The working principle of this utility model is as follows: First, wastewater to be tested is injected into the wastewater tank 3 through the feed hopper 9 at the top. Then, the control module 2 starts the motor 83 of the stirring mechanism 8, driving the rotating rod 81 and E-shaped stirring plate 82 inside the wastewater tank 3 to rotate, stirring the wastewater in the tank 3 to prevent sedimentation and ensure uniform concentration. Next, the control module 2 starts the electric push rod 76 of the switching mechanism 7, pushing the column 75 to rotate the positioning plate 71 with the positioning hole 72 and the support plate 74 with the support hole 73. This precisely aligns a membrane module 5 pre-installed in the positioning hole 72 and the support hole 73 with the sealing plate 63 on the side of the wastewater tank 3 and the connecting seat 66 of the testing mechanism 6. Then, two electric cylinders 65 push the connecting seat 66 upwards, sealing the inlet and outlet of the membrane module 5 through the rubber ring 12 in the groove of the connecting seat 66 and the bottom of the sealing plate 63. Afterwards, the control module 2 starts the water pump 61 on the inlet pipe 62 to pump the wastewater from the wastewater tank 3 through… The inlet pipe 62 delivers water to the membrane module 5 for filtration. After filtration, the wastewater flows into the wastewater tank 4 through the connecting seat 66 and the outlet pipe 67. The electromagnetic flowmeter 64 on the inlet pipe 62 and the outlet pipe 67 collects flow data in real time. The performance parameters such as the filtration flux and rejection rate of the membrane module 5 are calculated based on the measured data. After the current membrane module 5 is tested, the control module 2 first stops the water pump 61, controls the electric cylinder 65 to drive the connecting seat 66 to descend, and then drives the column 75 to rotate through the electric push rod 76 to switch the spare membrane module 5 to the test position and repeat the sealing and testing process. During the testing of the membrane module 5, another membrane module 5 can be pulled out from another positioning hole 72 and support hole 73, and the next membrane module to be tested can be inserted into the positioning hole 72 and support hole 73, thereby realizing continuous testing of the membrane module 5. When the test is completed, the control module 2 opens the solenoid valve 11 on the wastewater pipe 10 to discharge the wastewater, and the operator takes out the membrane module 5 to complete the entire testing process.
