Description

Technical Field

[0001] This utility model relates to the field of analyzer technology, specifically a water quality analyzer with an automatically replaceable filter. Background Technology

[0002] Existing water quality analysis instruments typically require continuous water flow during testing to ensure the accuracy of the results.

[0003] Patent CN214892216U discloses a filtration structure for a water quality testing instrument in a water plant. The structure includes a base with two sliding contact interfaces at the top. Extending sliders are mounted at both ends of the two contact interfaces, allowing for adjustable spacing between them. An extension block is located on the inner wall of the base, with a water-absorbing pad movably mounted on its upper end. This invention provides a filtration structure for a water quality testing instrument in a water plant. A container is placed into the base through the contact interfaces, which extend laterally under pressure. The extension distance is equal to the size of the sliding groove. When the container is removed, a tension spring causes the contact interfaces to reset. When the container is placed back into the base from the contact interfaces, an extension ring secures the contact ring to the interface. The contact ring can extend and retract with the contact interface. A contact ring is movably connected to the inner wall of the contact interface, allowing for partial cleaning of the water on the outer wall of the container. The water-absorbing pad absorbs water from the outer wall of the container.

[0004] As described above, because water often contains pollutants such as suspended particles, impurities, and algae, the filter screen inside the instrument is prone to clogging or decreased filtration efficiency. Once the filter screen fails, the water quality analysis results will be biased, and it may even lead to sensor damage. Filter screen replacement becomes an indispensable part of daily maintenance. However, manual filter screen replacement is frequent, inconvenient, time-consuming, and labor-intensive, affecting efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water quality analyzer with an automatic filter replacement function. This solves the problem that filter replacement is an indispensable part of daily maintenance, and that manual filter replacement is frequent, inconvenient, time-consuming, labor-intensive, and inefficient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water quality analyzer with an automatically replaceable filter screen, comprising:

[0007] The working box has a liquid supply hose connected to one side, a receiving pipe connected to the bottom of the inner wall of the working box, and an anti-slip support pad provided at the bottom of the working box.

[0008] A replacement assembly, one side of which is fixedly connected to one side of the inner wall of the working chamber, is used to automatically replace the filter screen of the water quality analyzer.

[0009] The mounting component is fixedly connected on one side to the replacement component on one side, and the mounting component is used for filter maintenance operations on the water quality analyzer.

[0010] Preferably, the rotation assembly includes a rotation motor fixedly connected to the inner wall of the work box, a mounting block fixedly connected to the top of the rotation motor, a rectangular groove opened on the top of the mounting block, and a rectangular insert plate movably connected to the inner wall of the rectangular groove.

[0011] Preferably, a supporting circular plate is fixedly connected to the top of the rectangular insert, and a lifting plate is fixedly connected to the center of the top of the supporting circular plate.

[0012] Preferably, the mounting assembly includes a loading ring fixedly connected to the surface of the rotation assembly, the surface of the loading ring having a limiting groove, and a bottom ring fixedly connected to the bottom of the inner wall of the loading ring.

[0013] Preferably, a filter screen is movably connected to the top of the bottom ring, and a connector plate is fixedly connected to the surface of the filter screen.

[0014] Preferably, a pressing plate is fixedly connected to the surface of the loading ring, a damping shaft is rotatably connected to the surface of the pressing plate, and a bifurcated baffle is fixedly connected to one side of the surface of the damping shaft.

[0015] This invention provides a water quality analyzer with an automatically replaceable filter. Compared with the prior art, it has the following advantages:

[0016] 1. This water quality analyzer with automatic filter replacement utilizes a rotating assembly. A revolving disc structure houses multiple filter units. When a filter becomes clogged or reaches the end of its lifespan, the control mechanism drives the disc to rotate, quickly switching the backup filter to the working position, thus achieving automatic filter replacement. Furthermore, the supporting disc plate for the filter can be separated from the mounting block, facilitating complete removal and simplifying equipment maintenance. This design addresses the problem that manual filter replacement is an indispensable part of daily maintenance, but is frequent, inconvenient, time-consuming, and labor-intensive, impacting efficiency. It ensures the continuity of water quality analysis and the stability of data acquisition, significantly reducing the frequency of manual intervention.

[0017] 2. This water quality analyzer with automatically replaceable filters utilizes a modular design, allowing the entire disc structure to be manually replaced after the filter array is fully used. This ensures fully automated operation while simplifying subsequent maintenance, avoiding the tediousness and potential contamination associated with disassembling individual filters. Compared to traditional single-filter designs, this device significantly extends the unattended operation cycle and is suitable for remote water quality monitoring, environmental remediation, and industrial circulating water testing, demonstrating significant practical value and promising prospects for wider adoption.

A bottom ring 53 is fixedly connected to the bottom of the inner wall of the loading ring 51. A filter screen 54 is movably connected to the top of the bottom ring 53. A connector plate 55 is fixedly connected to the surface of the filter screen 54. The connector plate 55 is compatible with the limiting groove 52. A pressing plate 56 is fixedly connected to the surface of the loading ring 51. A damping shaft 57 is rotatably connected to the surface of the pressing plate 56. A forked baffle 58 is fixedly connected to one side of the surface of the damping shaft 57. Utilizing the installation component 5, the entire structure of the wheel can be manually replaced by personnel after the filter group has been completely used. This ensures the fully automatic operation of the equipment and simplifies subsequent maintenance operations, avoiding the tediousness and potential pollution caused by disassembling each filter individually. Compared with traditional single filter designs, this device can significantly extend the unattended operation cycle and is suitable for scenarios such as remote water quality monitoring, environmental management, and industrial circulating water testing. It has good practical value and promising prospects for promotion.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] During operation, water flows down through the supply hose 2, passes through the filter screen 54, and solid impurities are filtered out. The water then flows through the receiving pipe 3 into the analyzer for thorough analysis. After the current filter screen 54 is fully loaded, the alternating motor 41 is activated. This motor, via the mounting block 42, drives the rectangular insert plate 44 and the supporting circular plate 45 to rotate, ultimately rotating the loading ring 51 and the filter screen 54. A new filter screen 54 is then rotated to the bottom of the supply hose 2, until all filter screens 54 in the supporting circular plates 45 have participated in filtration. For equipment maintenance, the lifting plate 46 moves the rectangular insert plate 44 upwards via the supporting circular plate 45, which, along with the mounting block... Separate the rectangular groove 43 in section 42, place the new bearing circular plate 45 and the filter screen 54 to be used in the original working position and continue to use it. To maintain the previously dirty filter screen 54, simply rotate the damping shaft 57 on the surface of the pressing plate 56 to rotate the bifurcated baffle 58 and the connecting plate 55 to alternate, pull up the filter screen 54, separate the connecting plate 55 from the limiting groove 52 in the loading ring 51, and the filter screen 54 can be taken out for maintenance and cleaning. Then put the filter screen 54 back on the top of the bottom ring 53, rotate the damping shaft 57 in the opposite direction, and the bifurcated baffle 58 will return to its original position and tightly limit and fix the connecting plate 55 and the filter screen 54. When the device is completely finished, restore the device.
