Description

Technical Field

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

[0002] Currently, filters are widely used in industrial production and daily life, playing a crucial role in ensuring stable system operation and product quality. Filter life prediction is therefore essential. It utilizes various methods and technologies to estimate the effective duration of filter use in advance, allowing users to know their failure time and thus enabling timely maintenance or replacement. This prevents adverse consequences such as deteriorated filtration efficiency and system malfunctions caused by overuse. Prediction methods include: analysis based on empirical data, referencing past usage records and industry best practices; inference through monitoring changes in operating parameters such as pressure differential, flow rate, and contaminant concentration; simulation using mathematical models or finite element analysis; and periodic testing, including visual inspection, performance testing, and non-destructive testing.

[0003] Currently, filter life prediction often relies on flow monitoring and contaminant concentration monitoring. The former monitors the flow rate of water after filtration, while the latter compares the contaminant content in the water before and after filtration. However, in actual use, existing devices often require frequent connection to different filters for prediction. But existing technologies have obvious drawbacks: they cannot quickly disassemble and reassemble the filters. Each test requires complicated disassembly and reassembly of the auxiliary detection device, which greatly affects the detection efficiency and is extremely inconvenient to use. The overall application has defects, and there is an urgent need to improve the design to enhance the practicality and convenience of filter life prediction devices. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a filter life prediction device to solve the problem that the prediction device cannot be quickly disassembled and assembled during the application of the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A filter life prediction device includes a turbine flow meter and a filter to be tested. Connecting pipes are fixedly installed on both sides of the turbine flow meter, and mounting mechanisms are fixedly installed on the outer ends of the connecting pipes. The filter to be tested is disposed on one side of the turbine flow meter. A connecting flange is installed on the outer side of the connecting pipe through the mounting mechanism. The connecting flange on the side closer to the turbine flow meter is connected to the output end of the filter to be tested.

[0007] The installation mechanism includes a sleeve and a plug. The sleeve is fixedly installed at the outer end of the connecting pipe, and the plug is fixedly installed on the side of the connecting flange near the turbine flow meter. The plug is inserted into the inside of the sleeve. A limit component is fixedly connected to the outside of the sleeve. An adjustment component is fixedly installed on the top of the limit component. The sleeve and the plug are snapped together by the limit component.

[0008] As a preferred technical solution, the limiting component includes a frame base and a snap-fit ​​arm. The frame base is fixedly installed on the outside of the sleeve, and sliding grooves are provided on both sides of the frame base. The snap-fit ​​arm is fixedly connected to both ends of the inner side of the connecting flange. The snap-fit ​​arm is disposed on both sides of the insertion tube. A limiting spring is fixedly connected inside the sliding groove. A slider is fixedly installed on the outside of the limiting spring. A snap-fit ​​arm is fixedly connected to the side of the slider near the snap-fit ​​arm. A snap-fit ​​groove is fixedly connected to the side of the snap-fit ​​arm near the snap-fit ​​arm. A snap-fit ​​block is fixedly connected to the end of the snap-fit ​​arm, and the snap-fit ​​block is inserted into the inside of the snap-fit ​​groove.

[0009] As a preferred technical solution, an electrochemical sensor is fixedly connected to the bottom of the frame near the filter to be tested in one of the two frame seats, and the detection end of the electrochemical sensor is located inside the sleeve.

[0010] As a preferred technical solution, an optical sensor is fixedly connected to the bottom of the frame that is farthest from the filter to be tested in the two frame seats, and the detection end of the optical sensor is located inside the sleeve.

[0011] As a preferred technical solution, the adjustment assembly includes a rail frame and a guide arm. The rail frame is fixedly installed at the top center of the frame base. A slide is slidably connected inside the rail frame. A guide frame is fixedly connected at the bottom center of the slide. The guide arm is fixedly connected to the top of the slider. A guide ramp is fixedly connected to the inner end of the guide arm. The guide ramp and the guide frame are connected in a transmission manner.

[0012] As a preferred technical solution, the lower end of the guide frame is generally arranged in an isosceles trapezoidal shape, and the bottom inclined surface of the guide frame is fitted and connected to the inclined surface of the guide plate.

[0013] As a preferred technical solution, a push rod is fixedly connected to the top of the carriage, and a pressing plate is fixedly connected to the top of the push rod through the rail frame.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this device, through its installation mechanism, can effectively improve the convenience and efficiency of filter testing. During use, the filter's built-in, non-disassembly-required connecting flange is used to connect the drain pipe and the filter to be tested. During testing, the tube is inserted into the sleeve, and the adjusting component moves the slider outward, causing the locking arm and locking block to move. After the tube is inserted into place, the limit spring resets, allowing the locking block to lock into the slot, completing the installation. The device is also equipped with a turbine flow meter, electrochemical and optical sensors, which can monitor flow and contaminants in real time, providing reliable data for filter life prediction.

[0016] Secondly, by setting up adjustment components, this device can effectively optimize the operation process, making filter installation and removal more efficient. During use, when removing the filter, pressing the press plate will cause the push rod, slide, and guide frame to move. The inclined surface of the guide frame will press against the guide plate, pushing the guide arm, slider, and locking arm to move outward. The locking block will separate from the slot, allowing the insertion tube to be pulled out. During installation, the process is reversed. After inserting the insertion tube, releasing the press plate will cause the limit spring to drive the locking block into the slot. The installation mechanisms at both ends of the device are designed identically, which facilitates the installation and maintenance of the drain pipe, improving overall convenience and maintenance efficiency.

[0023] Example

[0024] refer to Figures 1 to 5The filter life prediction device of this embodiment includes a turbine flow meter 1 and a filter to be tested 2. Connecting pipes 5 are fixedly installed on both sides of the turbine flow meter 1, and mounting mechanisms 3 are fixedly installed on the outer ends of the connecting pipes 5. The filter to be tested 2 is disposed on one side of the turbine flow meter 1. A connecting flange 4 is installed on the outer side of the connecting pipe 5 through the mounting mechanism 3. The connecting flange 4 on the side closer to the turbine flow meter 1 is connected to the output end of the filter to be tested 2.

[0025] The mounting mechanism 3 includes a sleeve 31 and an insert 32. The sleeve 31 is fixedly installed on the outer end of the connecting pipe 5, and the insert 32 is fixedly installed on the side of the connecting flange 4 near the turbine flow meter 1. The insert 32 is inserted into the inside of the sleeve 31. A limit assembly 33 is fixedly connected to the outside of the sleeve 31, and an adjustment assembly 34 is fixedly installed on the top of the limit assembly 33. The sleeve 31 and the insert 32 are snapped together by the limit assembly 33. During use, the device can utilize the existing filter output end's built-in connecting flange 4, which does not require disassembly, to connect it to the outside of the connecting pipe 5 through the mounting mechanism 3. Specifically, the insert 32 on the connecting flange 4 is inserted into the sleeve 31 at the outer end of the connecting pipe 5, and the adjustment assembly 34 is operated to move the slider in the limit assembly 33. Move 335 outward, stretching the limiting spring 334, and simultaneously moving the locking arm 336 and locking block 338 outward; after the insertion tube 32 is fully inserted into the sleeve 31, release the adjusting component 34, the limiting spring 334 returns to its original position, pull the slider 335 inward, and then allow the locking block 338 to accurately insert into the slot 337, achieving a tight connection between the sleeve 31 and the insertion tube 32, completing the rapid installation of the filter under test 2 and the turbine flow meter 1. After the fluid passes through the filter under test 2, it flows into the turbine flow meter 1 through the connecting pipe 5. The turbine flow meter 1 monitors the fluid flow rate changes in real time, providing an important basis for predicting the filter life. If the filter under test 2 needs to be removed, operate the adjusting component 34 again to separate the locking block 338 from the slot 337, and the insertion tube 32 can be easily pulled out.

[0026] refer to Figures 1-3The limiting assembly 33 includes a frame base 331 and a snap-fit ​​arm 332. The frame base 331 is fixedly installed on the outside of the sleeve 31. Slide grooves 333 are provided on both sides of the frame base 331. The snap-fit ​​arm 332 is fixedly connected to both ends of the inner side of the connecting flange 4. The snap-fit ​​arm 332 is located on both sides of the insertion tube 32. A limiting spring 334 is fixedly connected inside the slide groove 333. A slider 335 is fixedly installed on the outside of the limiting spring 334. A snap-fit ​​arm 336 is fixedly connected to the side of the slider 335 near the snap-fit ​​arm 332. A snap-fit ​​groove 3 is fixedly connected to the side of the snap-fit ​​arm 332 near the snap-fit ​​arm 336. 37. A locking block 338 is fixedly connected to the end of the locking arm 336. The locking block 338 is inserted into the slot 337. An electrochemical sensor 6 is fixedly connected to the bottom of the frame 331 closest to the filter under test 2. The detection end of the electrochemical sensor 6 is located inside the sleeve 31. An optical sensor 7 is fixedly connected to the bottom of the frame 331 furthest from the filter under test 2. The detection end of the optical sensor 7 is located inside the sleeve 31. During use, when it is necessary to connect the connecting pipe 5 of the filter under test 2 and the turbine flow meter 1, the connecting flange 4 is... The insertion tube 32 is inserted into the sleeve 31. The locking arms 332 at both ends of the inner side of the connecting flange 4 then move closer to the frame seat 331 on the outer side of the sleeve 31. The adjusting component 34 is operated, causing the slider 335 in the groove 333 of the frame seat 331 to slide outward against the elastic force of the limiting spring 334. The limiting spring 334 is stretched, and the slider 335 drives the locking arm 336 connected to it to move outward. The locking block 338 at the end of the locking arm 336 then moves away from the locking groove 337 on the locking arm 332. After the insertion tube 32 is fully inserted into the sleeve 31 and positioned, the adjusting component 34 is released, the limiting spring 334 returns to its original position, and the pull... The slider 335 moves inward, which in turn drives the clamping arm 336 and the clamping block 338 to move inward. The clamping block 338 is accurately inserted into the clamping groove 337 on one side of the clamping arm 332, completing the clamping and fixing of the sleeve 31 and the insertion tube 32, and realizing the stable installation of the filter under test 2. At the same time, the electrochemical sensor 6 near the bottom of the frame base 331 of the filter under test 2 and the optical sensor 7 far from the bottom of the frame base 331 of the filter under test 2 have their detection ends located inside the sleeve 31. They can detect the contaminants in the fluid flowing through the sleeve 31 in real time, providing contaminant-related data support for filter life prediction.

[0027] refer to Figures 4-5The adjusting assembly 34 includes a rail frame 341 and a guide arm 342. The rail frame 341 is fixedly installed at the top center of the frame base 331. A slide 343 is slidably connected inside the rail frame 341. A guide frame 344 is fixedly connected to the bottom center of the slide 343. The guide arm 342 is fixedly connected to the top of the slider 335. A guide ramp 345 is fixedly connected to the inner end of the guide arm 342. The guide ramp 345 and the guide frame 344 are connected by a transmission. The lower end of the guide frame 344 is generally arranged in an isosceles trapezoidal shape. The bottom slope of slide 343 is fitted and connected to the slope of guide plate 345. A push rod 346 is fixedly connected to the top of slide 343. The top of push rod 346 passes through rail frame 341 and is fixedly connected to pressing plate 347. When the adjusting component 34 of this device is working, when the operator presses down on pressing plate 347, pressing plate 347 drives push rod 346 to move down. Push rod 346 pushes slide 343 downward inside rail frame 341. Due to the guide plate fixedly connected in the middle of the bottom of slide 343... The lower end of the frame 344 is an isosceles trapezoid, and its bottom inclined surface is in contact with the inclined surface of the guide plate 345. As the guide frame 344 moves downward, according to the inclined plane transmission principle, the guide frame 344 will press the guide plate 345 outward. The guide plate 345 is fixedly connected to the inner end of the guide arm 342, so the movement of the guide plate 345 pushes the guide arm 342 outward. The guide arm 342 is fixedly connected to the top of the slider 335, which in turn drives the slider 335 to overcome the limiting spring 334 in the slide groove 333 of the frame seat 331. The elastic force slides outward, and the slider 335 moves outward, causing the connected clamping arm 336 and the clamping block 338 at the end of the clamping arm 336 to move outward synchronously, realizing the separation of the clamping block 338 from the clamping groove 337 on the clamping arm 332, making it easy for the insertion tube 32 to be pulled out from the sleeve 31 and completing the removal operation; conversely, when installing, the pressing plate 347 is released, the limit spring 334 is reset, and the slider 335 is pulled inward. Through the above reverse transmission process, the clamping block 338 is inserted into the clamping groove 337 to complete the fixation, which facilitates quick and easy installation and removal of the filter 2 to be tested.

[0028] Operating principle and advantages: This device, through the installation mechanism 3, significantly improves the convenience and efficiency of filter testing. During use, the connecting flange 4, which is standard on filters, can be used. No disassembly is required; simply connect the connecting flange 4 at the drain pipe inlet to the filter 2 under test. When testing is needed, insert the insertion tube 32 into the sleeve 31, and push the slider 335 outwards using the adjusting component 34. During this process, the slider 335 stretches the limit spring. 334, so that it is in a stretched state. As the slider 335 moves outward, the clamping arm 336 and the clamping block 338 on the clamping arm 336 move outward synchronously. When the insertion tube 32 is fully inserted into the sleeve 31, the adjusting component 34 is released, the limiting spring 334 is reset, and the slider 335 is pulled inward, which in turn drives the clamping arm 336 and the clamping block 338 to move inward, so that the clamping block 338 is accurately inserted into the slot 337. Through the tight clamping and limiting of the clamping block 338 and the slot 337, the insertion tube 32 is stably inserted and installed in the sleeve 31, thereby quickly completing the installation of the filter 2 to be tested.

[0029] During the testing process, this device is equipped with advanced testing equipment such as turbine flow meter 1, electrochemical sensor 6 and optical sensor 7. Turbine flow meter 1 can monitor the changes in fluid flow in real time, while electrochemical sensor 6 and optical sensor 7 can accurately detect the contaminants inside the filtered fluid. Through the coordinated work of these sensors, various parameters of the fluid after filtration can be obtained comprehensively and accurately, providing reliable data support for filter life prediction.

[0030] The adjustment component 34 further optimizes the operation process of this device, making the disassembly and assembly of the filter under test 2 more efficient and convenient. When disassembling or assembling the filter under test 2, the operator can press the pressing plate 347 to drive the push rod 346 downward. The downward movement of the push rod 346 causes the slide 343 to slide downward inside the rail frame 341, thereby pushing the guide frame 344 downward. The inclined surface at the bottom of the guide frame 344 contacts the guide inclined plate 345. Using the inclined surface guiding principle, the guide inclined plate 345 is squeezed outward, thereby pushing the guide arm 342 outward. The outward movement of the guide arm 342 drives the slider 335 outward, causing the locking arm 336 and the locking block 338 to move outward synchronously, finally separating the locking block 338 from the locking groove 337. At this time, the insertion tube 32 can be easily pulled out from the sleeve 31, quickly completing the disassembly operation of the filter under test 2.

[0031] When installing the filter under test 2, simply insert the insertion tube 32 into the sleeve 31 and then release the pressing plate 347. At this time, the limit spring 334 resets, pulling the slider 335 inward, which drives the locking block 338 at the end of the locking arm 336 to accurately insert into the slot 337 at the end of the locking arm 332, realizing the quick installation and removal of the filter under test 2. This design not only facilitates the quick installation and removal of the filter, but the installation mechanism 3 at the other end of the device also adopts a similar design, which can be used for the installation of drainage pipes. The design of the installation mechanisms 3 on both sides allows the device to be quickly installed and removed during maintenance, greatly improving the overall ease of use and maintenance efficiency of the device.
