Description

Technical Field

[0001] This utility model belongs to the field of filter element testing technology, and specifically relates to a filtration efficiency testing device. Background Technology

[0002] In modern industrial production and daily life, cylindrical filter cartridges are used as core components for liquid purification. With their high filtration performance and compact structural design, they are widely used in water treatment equipment, industrial liquid filtration systems, automotive engine lubricating oil filtration, chemical liquid purification and many other fields. As the market demand for filter cartridges continues to grow, the requirements for their quality testing are becoming increasingly stringent.

[0003] Currently, existing cylindrical filter cartridge testing devices on the market generally suffer from complex and cumbersome structural designs. Many testing devices employ multi-module splicing and multi-component linkage, which not only increases the manufacturing cost of the equipment but also makes the installation, debugging, and maintenance of the equipment extremely difficult. In actual testing operations, these devices often require operators to be familiar with complex operating procedures and manually control the start and stop of each testing step, parameter settings, etc. The testing steps are numerous and lack continuity, resulting in low overall testing efficiency. Furthermore, existing testing equipment largely relies on manual operation, making it difficult to achieve automated testing and meet the demand for rapid testing of filter cartridges in large-scale production scenarios, which seriously restricts the improvement of production efficiency and the control of production costs.

[0004] Furthermore, existing testing devices also have significant shortcomings in determining key testing indicators. Filtration rate, as an important indicator of filter cartridge performance, lacks accurate and rapid testing methods in current equipment, making it difficult to obtain accurate filtration rate data in a short time. Water quality testing before and after filtration also largely relies on traditional manual sampling and testing methods, which not only have long testing cycles but also make it difficult to guarantee the real-time nature and accuracy of the results. This testing method not only consumes a lot of manpower and resources but also cannot provide timely feedback on the quality status of the filter cartridge, failing to meet the timeliness requirements of modern industrial production for quality control. Therefore, it is evident that existing technologies have certain defects and deficiencies, necessitating improved design. Utility Model Content

[0023] Example

[0024] refer to Figures 1 to 4 A filtration efficiency testing device according to this embodiment includes a base plate 1. An adjustment mechanism 2 is fixedly connected to the middle of the rear top of the base plate 1. A testing mechanism 6 is fixedly installed on the front of the adjustment mechanism 2. A water supply mechanism 5 is fixedly installed on one side of the top of the base plate 1. A support frame 3 is fixedly installed in the middle of the top of the base plate 1. A sleeve 4 is fixedly installed on the top of the support frame 3. A filter element 7 to be tested is inserted inside the sleeve 4. Sealing gaskets are provided on both sides of the inside of the sleeve 4. The filter element 7 to be tested is inserted inside the sealing rings inside the sleeve 4.

[0025] The testing mechanism 6 includes a fixing block 61, which is fixedly installed on the front of the adjusting mechanism 2. A rail frame 62 is fixedly installed on the front of the fixing block 61. A drive motor 63 is fixedly installed at one end of the rail frame 62. A lead screw 64 is fixedly installed through the output end of the drive motor 63 and is rotatably connected to the inside of the rail frame 62. The two ends of the lead screw 64 have opposite threads. Both ends of the lead screw 64 are threadedly connected to sliders 65. A connecting rod 67 is fixedly installed on the front of the slider 65. A testing component 66 is provided at the front end of the connecting rod 67. When this filtration efficiency testing device is working, the filter element 7 to be tested is first inserted into the sleeve 4. The sealing gaskets on both sides of the sleeve 4 achieve a seal. The adjusting mechanism 2 can be adjusted. The position of the testing mechanism 6 facilitates its removal from the sleeve 4 to prepare for subsequent testing. The drive motor 63 is started, and its output end drives the lead screw 64 to rotate within the rail frame 62. Since the threads at both ends of the lead screw 64 rotate in opposite directions, the sliders 65 at both ends move relative to or away from each other along the lead screw 64. The sliders 65 drive the input water bucket 661 and output water bucket 662 in the testing assembly 66 to move through the connecting rod 67, accurately and quickly covering the outer surface of the sleeve 4 and completing the docking with the filter element 7 to be tested. At this time, the water supply mechanism 5 starts to work, delivering water to the input water bucket 661. After the water flows through the filter element 7 to be tested, it is discharged from the output water bucket 662, thereby realizing the testing of the filter element's filtration efficiency.

[0026] refer to Figures 1-4The detection component 66 includes an input water tank 661 and an output water tank 662. The input end of the input water tank 661 is connected to the output end of the water supply mechanism 5. A drain pipe 663 is fixedly installed at the output end of the output water tank 662. A water flow rate sensor 664 is fixedly connected to the top of the drain pipe 663, and a water quality sensor 665 is fixedly connected to the bottom of the drain pipe 663. The detection ends of both the water quality sensor 665 and the water flow rate sensor 664 are located inside the drain pipe 663. A water quality sensor 665 is also fixedly connected to the bottom of the input water tank 661. The output water... Water bucket 662 covers the output end of sleeve 4, and water input bucket 661 covers the input end of sleeve 4. Sealing gaskets are also provided on the inner sides of water input bucket 661 and water output bucket 662. The overall cross-sectional shape of slider 65 is convex, and the cross-sectional shape of the internal cavity of rail frame 62 is also convex. Mounting holes 8 are provided at the center of both ends of base plate 1, and the mounting holes 8 are countersunk holes. The outer corners of base plate 1 are all rounded. During the application of this device, when the detection component 66 is working, the water supply mechanism 5 delivers liquid to the water input bucket 661. The input end of water hopper 661 is connected to the output end of water supply mechanism 5, allowing liquid to flow in smoothly. Drive motor 63 drives lead screw 64 to rotate. Based on the characteristic of the reverse threads at both ends of lead screw 64, the U-shaped slider 65 moves relative to or away from each other within the U-shaped rail frame 62. Through connecting rod 67, it drives the input water hopper 661 and output water hopper 662 to move, so that output water hopper 662 covers the output end of sleeve 4 and input water hopper 661 covers the input end of sleeve 4. The sealing gaskets on the inner sides of both ensure the connection is sealed. After being filtered by the filter element 7, the liquid flows from output water hopper 662. The water flow rate sensor 664 at the top of the drain pipe 663 monitors the liquid flow rate in real time to calculate the filtration efficiency. The water quality sensor 665 at the bottom of the input water tank 661 detects the liquid indicators before filtration, and the water quality sensor 665 at the bottom of the drain pipe 663 detects the liquid indicators after filtration. By comparing and analyzing data such as impurity content and ion concentration, the performance of the filter element is comprehensively evaluated. In addition, the countersunk holes at both ends of the substrate 1 facilitate the installation and fixation of the device, and the external rounded corner design can avoid bumps during operation and improve the safety of use.

[0027] refer to Figures 1-3The water supply mechanism 5 includes a mounting plate 51, which is fixedly mounted on the back of the base plate 1 near the input water tank 661. A water tank 52 is fixedly mounted on the top of the mounting plate 51. A water pump 53 is fixedly mounted on the front top of the mounting plate 51. The input end of the water pump 53 is connected to the bottom of the water tank 52. A hose 54 is fixedly mounted on the output end of the water pump 53. The output end of the hose 54 is connected to the input end of the input water tank 661. A water inlet pipe 55 is fixedly connected to the upper back of the water tank 52. A connecting flange 56 is fixedly connected to the rear end of the water inlet pipe 55 and the outer end of the drain pipe 663. A regulating mechanism is also included. Component 2 includes a frame 21, which is fixedly installed at the top rear center of the base plate 1. An electric push rod 22 is fixedly connected inside the frame 21. A connecting plate 23 is fixedly installed through the output end of the electric push rod 22. A movable plate 24 is fixedly installed at the front end of the connecting plate 23. A fixing block 61 is fixedly installed in the center of the front of the movable plate 24. A guide rail 25 is fixedly installed on the front of the frame 21. The movable plate 24 is slidably connected to the inside of the guide rail 25. The internal cross-sectional shape of the guide rail 25 and the cross-sectional shape of the movable plate 24 are both set as convex. A chassis is fixedly installed on the upper front of the movable plate 24. Furthermore, the front of the chassis is equipped with a touch screen display. During the use of this device, after the water pump 53 of the water supply mechanism 5 is started, water is drawn from the bottom of the water tank 52 at the top of the mounting plate 51. The water is then transported through the hose 54 to the input water bucket 661, enters the sleeve 4, and is filtered by the filter element 7. After filtration, the water is discharged through the output water bucket 662, thus achieving a better detection effect. The water tank 52 can be replenished with water through the water inlet pipe 55. The connecting flange 56 at the outer end of the water inlet pipe 55 and the drain pipe 663 facilitates the external pipeline. When the electric push rod 22 of the adjusting mechanism 2 extends or retracts, it drives the connecting plate. The movable plate 23 and movable plate 24 slide along the U-shaped guide rail 25 on the front of the frame 21, thereby adjusting the position of the detection mechanism 6 fixed on the movable plate 24 so that it is precisely aligned with the filter element 7 to be tested. The U-shaped cross section of the movable plate 24 matches the guide rail 25 to ensure smooth sliding. The control system inside the chassis receives operation commands through the touch screen and collects data from the water flow rate sensor 664 and the water quality sensor 665, displaying the filtration efficiency and water quality indicators in real time, realizing the integrated control of human-machine interaction and automated detection. The entire process completes the efficient detection of the filter element through the cooperation of mechanical transmission and electronic system.

[0028] Operating Principle and Advantages: During application, this device can perform rapid and efficient testing. To test the filtration efficiency, the filter element to be tested is first inserted into the sleeve 4. Then, the drive motor 63 is started. Once started, the output of the drive motor 63 rotates the lead screw 64. Because the threads at both ends of the lead screw 64 rotate in opposite directions, the two sliders 65 inside the rail frame 62 can move relative to or away from each other along the lead screw 64. The movement of the sliders 65 drives the input water tank 66 in the detection assembly 66 via the connecting rod 67. The water pump 51 and the output water tank 662 move back and forth, accurately and quickly covering the outer surface of the sleeve 4 to achieve docking with the filter element 7 under test. At the same time, the water pump 53 in the water supply mechanism 5 draws water from the water tank 52 and delivers it to the input water tank 661 through the hose 54. After the water flows through the filter element 7 under test, it is discharged from the output water tank 662. The entire process does not require frequent manual adjustment of the position of the testing components. Only a simple equipment start-up operation is needed to achieve rapid water supply and testing, which greatly improves the testing efficiency and reduces the labor intensity of the operators.

[0029] During application, this device also offers convenience in filter element installation / removal and data acquisition. The sealing gaskets at both ends of the sleeve 4 provide a good seal when installing the filter element 7 to be tested. They can be quickly inserted into the sleeve 4, and the elastic compression of the sealing rings achieves a secure seal. The operation is simple and quick, effectively shortening the filter element installation time. After testing, the drive motor 63 is directly started, driving the lead screw 64 to move the slider 65 outward. This causes the input water bucket 661 and output water bucket 662 to separate from the sleeve 4, allowing the filter element to be quickly removed. It is evident that this device, with its lead screw 64 and sliding drive design, enables rapid installation and removal of the filter element, effectively... To improve the testing efficiency of the filter element under test, during the testing process, the water flow rate sensor 664 at the top of the drain pipe 663 can monitor the flow rate data of the liquid after passing through the filter element 7 under test in real time, providing an accurate basis for calculating the filtration rate; while the water quality sensors 665 at the bottom of the drain pipe 663 and the bottom of the input water tank 661 respectively detect the liquid before and after filtration in real time. By analyzing the changes in multiple indicators such as impurity content and ion concentration in the water, the filtration effect of the filter element is comprehensively evaluated. These sensors transmit the collected data to the control system in the chassis in real time and present it intuitively through the touch screen. The testing personnel can quickly obtain comprehensive and accurate test results, truly realizing the speed and efficiency of the testing process.
