Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, and in particular to an online sulfate monitor. Background Technology

[0002] In the fields of industrial production and environmental monitoring, the content of sulfate ions is one of the important indicators for assessing water quality. Excessive sulfate concentration may lead to problems such as equipment corrosion and eutrophication of water bodies. Therefore, it is necessary to conduct accurate and real-time online monitoring of sulfate content in various water bodies.

[0003] Traditional methods for monitoring sulfate ions have limitations. The distribution of sulfate ions in liquids often varies due to factors such as liquid settling or uneven flow, leading to concentration differences. Direct sampling can easily result in data distortion due to localized concentration deviations. Traditional stirring devices are mostly simple blade structures with poor compatibility with the container's inner wall, making it difficult to achieve uniform mixing throughout the liquid. Dead zones are easily formed, especially in the middle and bottom of the treatment tank, further exacerbating the uneven distribution of sulfate ions. Utility Model Content

[0024] A second outer ring 705 is movably connected to the top of the baffle 704. A middle filter plate 706 is fixedly installed on the inner wall of the second outer ring 705. The tops of both the middle filter plate 706 and the first outer ring 701 are slidably connected to a discharge pipe 707. Here, the baffle 704 and the middle filter plate 706 are movably connected, which facilitates the installation and removal of the middle filter plate 706 and is easy to clean and maintain. The second outer ring 705 enhances the structural strength of the middle filter plate 706 and extends its service life. The middle filter plate 706 and the first outer ring 701 are slidably connected to the discharge pipe 707, allowing the filter assembly 7 to move relative to the discharge pipe 707. In conjunction with the third elastic element 703, it can generate slight vibration when liquid impacts, preventing impurities from clogging the filter plate and ensuring the continuity of filtration.

[0025] The top of the feed pipe 707 is fixedly installed to the bottom of the treatment tank 1. A water pump outlet valve 6 is fixedly installed on the top of the feed pipe 707. The side of the third elastic element 703 away from the small perforated plate 702 is fixedly installed at the bottom of the middle perforated plate 706. Here, the connection between the feed pipe 707 and the treatment tank 1, the water pump outlet valve 6, and the connection between the third elastic element 703 and the middle perforated plate 706 are defined. The feed pipe 707 provides a channel for liquid flow, and its fixed connection to the bottom of the treatment tank 1 ensures a stable connection. The water pump outlet valve 6 can accurately control the liquid discharge speed and volume. The third elastic element 703 connects the small perforated plate 702 and the middle perforated plate 706, so that the two form a linkage during filtration, enhancing the vibration effect, further preventing clogging, and improving the working efficiency of the filter assembly 7.

[0026] The bottom of the support column 4 is fixedly installed to the top of the treatment tank 1. A monitoring instrument is fixedly installed on the inner wall of the collection box 8. The controller 9 is electrically connected to the motor 3, the monitoring instrument, and the water pump outlet valve 6. Here, the support column 4 is fixed to the top of the treatment tank 1 to ensure the motor 3 is securely installed and to reduce vibration during operation. The monitoring instrument inside the collection box 8 can monitor the collected liquid online, enabling real-time data acquisition. The controller 9 is electrically connected to the motor 3, the monitoring instrument, and the water pump outlet valve 6, and can automatically adjust the speed of the motor 3 and the opening and closing of the water pump outlet valve 6 based on the monitoring data, achieving intelligent operation of the equipment, improving the timeliness and accuracy of monitoring, and reducing the intensity of manual operation. Working principle: The sulfate-containing liquid to be monitored is injected into the treatment tank 1 through the feed pipe 5 until the appropriate liquid level is reached. Press the controller 9 to start the motor 3. The motor 3 starts working under the stable support of the support column 4, and its output end drives the long rod 201 to rotate. When the long rod 201 rotates, the stirring rod 208 on the outer wall rotates accordingly. Since the outer wall of the stirring rod 208 is adapted to the inner wall of the middle part of the treatment tank 1, it can fully stir the liquid in the tank, making the sulfate in the liquid more evenly distributed, providing an accurate sample for subsequent monitoring. At the same time as the long rod 201 rotates, the single-sided gear 202 on the outer wall rotates synchronously. The single-sided gear 202 meshes with the rack 206, driving the rack 206 to slide along the top of the treatment tank 1. When the rack 206 moves, it drives the L-shaped bent rod 203 to slide under the limiting action of the limiting plate 204. The movement of the L-shaped bent rod 203 compresses the first elastic element 205. The movement of the L-shaped bent rod 203 causes the impact plate 207 at its end to impact the relevant parts of the treatment tank 1. When the single-sided gear 202 rotates to the point where the toothless part separates from the rack 206, the first elastic element 205 resets, driving the L-shaped bent rod 203 to move in the opposite direction, causing the impact plate 207 at the other end to impact the relevant parts of the treatment tank 1, which can prevent liquid from adhering to the tank wall. The rotation of the long rod 201 drives the long plate 209 at the bottom to rotate. The long plate 209 drives the round rod 211 and the scraper 213 to rotate through the stirring rod 208. Under the elastic force of the second elastic element 212, the outer wall of the scraper 213 is always in close contact with the bottom inner wall of the treatment tank 1. As the long rod 201 rotates, it thoroughly scrapes the bottom of the tank, preventing impurities from accumulating and ensuring the liquid is not affected by residual impurities. After the liquid is evenly stirred and the bottom of the tank is cleaned by the scraper 213, the water pump outlet valve 6 is opened by the controller 9. The liquid in the treatment tank 1 flows to the bottom filter assembly 7 under gravity. The liquid first contacts the middle drain plate 706, which is movably connected to the baffle 704 under the support of the third elastic element 703. Simultaneously, the outer walls of the middle drain plate 706 and the first outer ring 701 are slidably connected to the discharge pipe 707. When the liquid impacts the middle drain plate 706, the third elastic element 703 undergoes elastic deformation, causing the middle drain plate 706 and the small drain plate 702 to vibrate slightly, preventing impurities from clogging the drain plates. The middle filter plate 706 performs preliminary filtration of the liquid, trapping larger impurities. The filtered liquid then enters the small filter plate 702 through the middle filter plate 706, where it undergoes secondary filtration to further remove fine impurities. The first outer ring 701 provides stable support for the small filter plate 702, ensuring the filtration effect. The liquid filtered by the filter assembly 7 flows into the collection box 8 through the feed pipe 707, where it can be detected by the monitoring instruments on the inner wall of the collection box 8.
