Description

Technical Field

[0001] This utility model relates to the field of liquid level monitoring technology, and more specifically, to a liquid level monitoring device for an emulsion tank. Background Technology

[0002] In industrial production, emulsions are widely used as important cooling and lubricating media in industries such as machining, mining, and metallurgical rolling. The emulsion tank, as the core equipment for emulsion storage and circulation, directly affects the continuity of the production process, equipment safety, and emulsion utilization efficiency due to its internal liquid level. For example, in underground longwall mining faces, emulsion pump stations provide power to hydraulic supports. If the emulsion tank level is below the safety threshold, air will be drawn into the pump station, causing pressure fluctuations in the hydraulic system. This not only affects the accuracy of the hydraulic supports' movements but may also damage the pump station motor due to idling. Conversely, if the level is too high, emulsion may overflow during circulation, resulting in waste and environmental pollution. Therefore, real-time and accurate monitoring of the emulsion tank level is crucial for ensuring stable industrial production. Currently, the main method for monitoring the liquid level in emulsion tanks in the industrial sector is automatic monitoring, with existing technologies primarily employing capacitive or ultrasonic level sensors. While capacitive level sensors detect liquid level by utilizing differences in the dielectric constant of the medium, enabling continuous measurement, changes in the concentration and temperature of the emulsion significantly affect the dielectric constant, leading to measurement accuracy drift. Furthermore, the sensor probe is susceptible to emulsion contamination and scaling, requiring frequent maintenance and calibration after long-term use, increasing operational costs. Ultrasonic level sensors calculate liquid level by emitting ultrasonic waves and receiving reflected waves. While offering the advantage of non-contact measurement, the presence of foam or mist within the emulsion tank, or complex tank wall structures causing acoustic wave reflection interference, severely impacts measurement accuracy, especially at low or critical high liquid levels, where false alarms or missed alarms are prone to occur. Utility Model Content The main objective of this invention is to provide an emulsion tank level monitoring device that can effectively solve the problems in the background art.

[0003] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An emulsion tank level monitoring device includes a storage tank, wherein a detection component is movably sleeved inside the storage tank; The detection assembly includes a floating ring, with a silicone ring scraper fixedly fitted onto the outer surface of the floating ring.

Detailed Implementation

[0011] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0012] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of this utility model provides an emulsion tank level monitoring device, including a storage tank 1 and a detection component 2, wherein the detection component 2 is movably sleeved inside the storage tank 1; like Figures 4-5As shown, the detection component 2 includes a floating ring 21. A silicone ring scraper 22 is fixedly sleeved on the outer surface of the floating ring 21. A support plate 23 is fixedly connected inside the floating ring 21. A fixed cover 24 is fixedly connected to the top of the support plate 23. A fixed gear 25 is fixedly connected to the bottom of the support plate 23. A rotary motor 26 is fixedly connected inside the fixed cover 24 at the top of the support plate 23. A support frame 27 is fixedly connected to the output end of the rotary motor 26. Rotating rods 29 are rotatably mounted at both ends of the support frame 27. Multiple needles 210 are fixedly sleeved on the outer surface of the rotating rods 29. A transmission bevel gear 211 is fixedly sleeved at the opposite end of the two rotating rods 29. The outer surface of the transmission bevel gear 211 meshes with the outer surface of the fixed gear 25. A baffle 28 is fixedly connected to one side of both ends of the support frame 27.

[0013] Specifically, by sliding the floating ring 21 from top to bottom inside the fixed box 11, the emulsion attached to the surface of the fixed box 11 is quickly pushed to the bottom of the fixed box 11. This avoids the situation where, if the liquid level changes abruptly, such as a rapid drop due to pipeline leakage or an abnormal rise due to a failure of the liquid replenishment system, some emulsion will adhere to the inner wall of the fixed box 11, causing abnormal detection by the ultrasonic liquid level sensor 16 and affecting the detection accuracy.

[0014] like Figure 2 As shown, the storage box 1 includes a fixed box 11. Limiting rods 15 are fixedly connected to both ends inside the fixed box 11. A support base 12 is fixedly connected to the bottom of the fixed box 11. A stirring motor 13 is fixedly connected to the bottom of the fixed box 11. A stirring paddle 14 is fixedly connected to the output end of the stirring motor 13. The stirring paddle 14 is rotatably installed at the lower end of the fixed box 11.

[0015] The support plate 23 is movably sleeved on the outer surface of the two end limit rods 15, the silicone ring scraper 22 is slidably installed on the inner wall of the fixed box 11, and the baffle 28 and the rotating rod 29 are rotatably installed on the bottom of the support plate 23.

[0016] Specifically, the support plate 23 is limited by the limiting rod 15 to prevent the floating ring 21 from rotating. Therefore, when the rotary motor 26 controls the support frame 27 to rotate, the baffles 28 at both ends push the bubbles on the surface of the emulsion to the side of the baffles 28. At the same time, the support frame 27 drives the rotating rod 29 to rotate. Through the meshing of the fixed gear 25 and the transmission bevel gear 211, the rotating rod 29 rotates itself, causing the needle 210 to break the bubbles on the surface of the emulsion, thus preventing the bubbles on the surface of the emulsion from affecting the detection accuracy of the ultrasonic liquid level sensor 16.

[0017] like Figure 3As shown, a vacuum pump 19 is fixedly connected to the top of the fixed box 11. One end of the vacuum pump 19 is fixedly connected to an air pipe, and one end of the air pipe is connected to the interior of the fixed box 11. A pull rope displacement sensor 17 is fixedly connected to the top of the fixed box 11. The bottom of the pull rope displacement sensor 17 is fixedly connected to the top of the fixed cover 24. An audible and visual alarm 18 is fixedly connected to the top of the fixed box 11. An ultrasonic liquid level sensor 16 is fixedly connected to one end of the top of the fixed box 11. The ultrasonic liquid level sensor 16 is electrically connected to the audible and visual alarm 18.

[0018] One end of the top of the fixed box 11 is fixedly connected to the liquid inlet pipe 111, and the liquid inlet pipe 111 is equipped with a solenoid valve 110.

[0019] The floating ring 21 is moved up and down inside the fixed box 11 by the rope displacement sensor 17, and the corresponding liquid level change of the emulsion is sensed by the ultrasonic liquid level sensor 16. When the liquid level of the emulsion inside the fixed box 11 is low, the solenoid valve 110 is opened by the electrical signal, so that the emulsion is automatically added into the fixed box 11 through the liquid inlet pipe 111. The stirring paddle 14 is rotated inside the fixed box 11 by the stirring motor 13, so that the emulsion inside the fixed box 11 is mixed evenly.

[0020] The working process of this utility model is as follows: During use, as the emulsion is used, its level gradually decreases. At this time, the silicone ring scraper 22 floating on the surface of the emulsion gradually descends with the emulsion level. When the floating ring 21 descends, the fixed cover 24 pulls the pull rope displacement sensor 17 to extend, and the pull rope displacement sensor 17 detects the change in the emulsion level inside the fixed box 11. At the same time, the ultrasonic level sensor 16 senses the corresponding change in the emulsion level. When there is a large difference between the distance detected by the pull rope displacement sensor 17 and the change detected by the ultrasonic level sensor 16, it indicates that there are many air bubbles on the surface of the emulsion. When the rotary motor 26 controls the support frame 27 to rotate, the baffles 28 at both ends push the air bubbles on the surface of the emulsion to the side of the baffles 28. At the same time, the support frame 27 drives the rotating rod 29 to rotate. Through the meshing of the fixed gear 25 and the transmission bevel gear 211, the rotating rod 29 rotates itself, causing the needle 210 to break the air bubbles on the surface of the emulsion, thus preventing the air bubbles from affecting the detection accuracy of the ultrasonic level sensor 16.

[0021] In addition, as the emulsion level drops, the floating ring 21 slides from top to bottom inside the fixed box 11, quickly pushing the emulsion adhering to the surface of the fixed box 11 to the bottom of the fixed box 11. When the liquid level of the emulsion inside the fixed tank 11 is low, the ultrasonic liquid level sensor 16 controls the solenoid valve 110 to open via an electrical signal, so that the emulsion is automatically added to the inside of the fixed tank 11 through the liquid inlet pipe 111, and the stirring motor 13 controls the stirring paddle 14 to rotate inside the fixed tank 11, so that the emulsion inside the fixed tank 11 is mixed evenly.
