Description

Technical Field

[0001] This utility model relates to the field of circulating cooling water quality detection technology, specifically to an online circulating cooling water quality monitoring device. Background Technology

[0002] In industrial production processes, circulating cooling water systems are widely used, and their water quality directly affects the normal operation of the system, equipment lifespan, and production efficiency. Therefore, online water quality monitoring of circulating cooling water is crucial.

[0003] Currently, existing online water quality monitoring devices for circulating cooling water have many shortcomings in terms of structural design and functional implementation. On the one hand, the water quality detection probe is in long-term contact with the circulating cooling water. Due to the various minerals and impurities contained in the water, the end of the probe in contact with the water is prone to crystalline scale buildup after a period of use. This scale not only affects the accuracy of the probe's detection of water quality parameters, reducing detection precision, but may also lead to probe corrosion, shortening its service life. Furthermore, existing monitoring devices often lack effective automatic cleaning and maintenance mechanisms for the water quality detection probe, usually requiring manual periodic removal and cleaning. This not only consumes a lot of manpower and time, but may also affect the monitoring results due to untimely or incomplete cleaning.

[0004] Therefore, we propose an online water quality monitoring device for circulating cooling water. Utility Model Content

[0005] The purpose of this invention is to provide an online water quality monitoring device for circulating cooling water to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online water quality monitoring device for circulating cooling water, comprising a circulating cooling pool, a second threaded rod, and an acid washing tank. A support column is fixedly connected to the top of the circulating cooling pool, and a first threaded rod is rotatably connected to one side of the support column. A first threaded slider is threadedly connected to one end of the first threaded rod, and a water quality detection probe is fixedly connected inside the first threaded slider. A second threaded rod is rotatably connected to one side of the support column, and a second threaded slider is threadedly connected to one end of the second threaded rod. An L-shaped connecting ring is rotatably connected to the inner wall of the second threaded slider. Two sets of scrapers of different heights are installed inside the L-shaped connecting ring. An acid washing tank is installed on one side of the support column, and a clean water tank is installed on another side of the support column. Spray rings are installed at the top and bottom of the L-shaped connecting ring, and the two spray rings are respectively connected to the acid washing tank and the clean water tank.

[0007] Preferably, the L-shaped connecting ring is rotatably connected to a connecting ring inside, and the inner wall of the connecting ring is provided with arc-shaped grooves at equal intervals. The two sets of scrapers are slidably connected to the inside of the L-shaped connecting ring. One end of the scraper is fixedly connected to a deflector. The L-shaped connecting ring is provided with sliding grooves at equal intervals. The deflector is slidably connected to the sliding grooves and arc-shaped grooves respectively. A fan-shaped toothed ring is fixedly connected to the outer wall of the connecting ring. A rack is slidably connected to the inside of the L-shaped connecting ring along its length. One end of the rack is fixedly connected to a first spring, and the other end of the rack is fixedly connected to a trapezoidal block. A guide rod is slidably connected to the inside of the L-shaped connecting ring in the width direction. One end of the guide rod is designed to be inclined, and the inclined end of the guide rod contacts the inclined surface of the trapezoidal block.

[0008] Preferably, a washer is fixedly connected to one end of the guide rod, and a second spring is sleeved on one end of the guide rod. One end of the second spring is fixedly connected to the washer, and the other end of the second spring is fixedly connected to the inside of the L-shaped connecting ring.

[0009] Preferably, a function groove is provided on one side of the support column, and the inner wall of the bottom end of the function groove is designed to be inclined.

[0010] Preferably, the elastic force of the first spring is greater than that of the second spring.

[0011] Preferably, a contact switch is fixedly connected to the top of the support column, and a controller is fixedly installed on one side of the support column.

[0012] Preferably, a stepper motor is fixedly connected to the top of the second threaded slider, and the output end of the stepper motor is fixedly connected to one end of the L-shaped connecting ring.

[0013] Preferably, two motors are installed at the top of the support column, and the output ends of the two motors are fixedly connected to the first threaded rod and the second threaded rod, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Automatic cleaning of water quality testing probes is achieved, reducing manual intervention: Through the cooperation of structures such as the first threaded rod, the first threaded slider, the contact switch, the controller, and the stepper motor, the device can automatically trigger the cleaning process after the water quality testing probe has been used for a period of time. There is no need for manual removal and cleaning of the probe, which greatly saves manpower and time costs, and avoids the problem of affecting the monitoring effect due to untimely manual cleaning.

[0016] Comprehensive and efficient cleaning: This device uses a combination of physical scraping and chemical cleaning to clean the water quality detection probe. Physically, the close proximity and movement of the scrapers effectively removes crystalline scale from the probe's outer wall. Chemically, the lower spray ring sprays acid solution for a secondary cleaning of the probe surface, ensuring thorough cleaning. In addition, the water sprayed from the upper spray ring removes residual acid and impurities from the probe surface during its descent, further enhancing the cleaning effect.

[0017] Protecting the water quality testing probe and extending its service life: During the cleaning process, the inner diameter of the scraper can be adjusted according to the position and condition of the probe. When the scraper rises, it moves closer to the outer wall of the probe to scrape away scale. During non-scraping phases, the inner diameter is larger than the outer diameter of the probe, avoiding unnecessary wear on the probe. At the same time, the concentration of the acid solution is controlled at 5%-10% citric acid, which can effectively remove scale without causing serious corrosion to the stainless steel probe, thereby extending the probe's service life.

[0028] The area enclosed by the two sets of scrapers 9 is larger than the outer diameter of the water quality detection probe 5.

[0029] A connecting ring 21 is rotatably connected inside the L-shaped connecting ring 8. Arc-shaped grooves 22 are equidistantly formed on the inner wall of the connecting ring 21. Two sets of scrapers 9 are slidably connected to the inside of the L-shaped connecting ring 8. A lever 23 is fixedly connected to one end of each scraper 9.

[0030] Working principle:

[0031] At this time, the motor drives the first threaded rod 3 to move to the lowest end, inserts the water quality detection probe 5 into the circulating cooling pool 1 to detect the water quality of the circulating cooling water, and at this time the ring end of the L-shaped connecting ring 8 is far away from the support column 2.

[0032] After the water quality probe 5 has been used for a period of time, crystalline scale will adhere to the end in contact with water. At this time, the motor drives the first threaded rod 3 to rotate, causing the first threaded slider 4 to rise until it reaches its highest point. At this point, the contact switch 14 is activated, and the controller 15 starts the stepper motor 16. The stepper motor 16 drives the L-shaped connecting ring 8 to rotate until the guide rod 29 on the L-shaped connecting ring 8 abuts against the support column 2 and is displaced. This causes the guide rod 29 to pull up the second spring 32, and pushes the inclined surface of the trapezoidal body 28 through the inclined end of the guide rod 29. This causes the trapezoidal block 28 to squeeze the first spring 27 through the rack 26, and the rack 26 to move. This causes the fan-shaped toothed ring 25 and the connecting ring 21 to rotate, ultimately causing the pusher pins 23 on the scraper 9 to move away from each other under the action of the sliding groove 24 and the arc groove 22. At this point, the inner diameter of the scraper 9 is much larger than the outer diameter of the water quality probe 5. At this time, another motor on the support column 2 is activated, causing the second threaded rod 6 to rotate. At this time, the L-shaped connecting ring... As the second threaded slider 7 rises, the guide rod 29 slides along one side of the support column 2. When the guide rod 29 moves to the bottom of the action groove 13, its inclined design at the bottom causes the guide rod 29 to move slowly. Under the action of the first spring 27, the rack 26 drives the connecting ring 21 to rotate, causing the two sets of scrapers 9 to move closer to each other again and contact the outer wall of the water quality detection probe 5. As the second threaded slider 7 rises, the two sets of scrapers 9 clean the crystallized scale on the outer wall of the water quality detection probe 5 (stainless steel material). The spray ring 12 located below connects to the acid washing tank. 10 (5%-10% citric acid), at this time, acid solution is also sprayed out to chemically clean the surface of water quality detection probe 5. When the L-shaped connecting ring (8) rises to the highest point, it is left to stand for 10 minutes. Finally, during the downward overshoot, clean water is sprayed out through the spray ring 12 above to clean the surface of water quality detection probe 5. The above cleaning method can be operated according to the usage of water quality detection probe 5. In addition, a guide pipe is installed on the recirculating cooling pool 1 to catch the cleaning acid and cleaning solution.
