[0001] This utility model relates to the field of chemical technology, and in particular to a remote level transmission device for alkali storage tanks. Background Technology
[0002] In the chemical and related fields, liquid level monitoring of alkali storage tanks is crucial. Traditional liquid level measurement methods often have limitations such as low accuracy, poor real-time performance, or difficulty in remote monitoring. With the continuous development of industrial automation and intelligence, higher requirements are placed on the accurate measurement and remote transmission of liquid level in alkali storage tanks. The storage and use of alkali solution are common operations. However, accurate monitoring of the liquid level in alkali storage tanks is crucial for the safety and stability of the production process. Traditional liquid level monitoring methods may have problems such as low accuracy, insufficient real-time performance, and difficulty in remote monitoring. Therefore, we propose a new remote liquid level transmission device for alkali storage tanks. Utility Model Content

[0008] By adopting the above technical solution, the active component, through the combination of slider, capacitor plate, index block and float, realizes real-time monitoring and display of liquid level height.
[0009] Preferably, the indicator block is located on the front side of the scale plate, and the float has a spherical structure.
[0010] By adopting the above technical solution, the float adopts a spherical structure, which gives it better buoyancy and stability, and reduces misjudgment caused by liquid fluctuations.
[0011] Preferably, the slider is slidably connected within the groove.
[0012] By adopting the above technical solution, the sliding connection of the slider in the chute ensures that it can move smoothly when the liquid level changes, avoiding jamming or misalignment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] In this invention, the float moves with the liquid level, causing the slider to move, and the change in the distance between the capacitor electrode and the measuring plate causes the capacitance value to change, which is then converted into an electrical signal. This method can accurately reflect the change in liquid level height. With the help of the display panel, remote display and monitoring are possible, allowing operators to keep track of the liquid level information in real time from a location far from the storage tank, thus improving the convenience and timeliness of monitoring.
[0019] In this invention, the pressure at the bottom of the storage tank is converted into liquid level measurement. Based on Archimedes' principle, the liquid level can be measured relatively accurately. The distance change of the capacitor plates is converted into a standard 420mA signal and transmitted to the DCS A card for reception. The signal is then displayed through the monitoring software of the human-machine interface, realizing standardized signal transmission and visualization, which facilitates data processing and interpretation.

[0028] Please see Figure 1-4 This utility model provides a technical solution:
[0029] A remote liquid level transmission device for an alkali storage tank includes a storage tank body 1, a base 6 fixedly connected to the lower end of the storage tank body 1, support feet 7 fixedly connected to the four corners of the lower end of the base 6, a drain pipe 5 inserted through the left side of the outer surface of the storage tank body 1, a cover plate 8 fixedly connected to the upper end of the storage tank body 1, a display panel 4 fixedly connected to the front of the outer surface of the storage tank body 1, an inlet pipe 2 fixedly connected to the upper left side of the cover plate 8, and a main body device 3 inserted through the upper front of the cover plate 8.
[0030] In this embodiment, the main device 3 includes a measuring plate 34, a scale plate 33 is fixedly connected to the left end of the measuring plate 34, a slide groove 35 is opened at the front end of the measuring plate 34, a movable component 36 is movably connected in the slide groove 35, a pressure gauge 31 is fixedly connected to the upper end of the measuring plate 34, an alarm 32 is fixedly connected to the right side of the pressure gauge 31, the measuring plate 34 is located inside the storage tank 1; the height of the measuring plate 34 is the same as the height of the inner wall of the storage tank 1; the alarm 32 is electrically connected to the display panel 4 through a wire.
[0031] With the above scheme: the height of the measuring plate 34 is the same as the height of the inner wall of the storage tank 1, ensuring that the slider 362 and the float 364 can move freely within the entire liquid level range. The measuring plate 34 is the main part of the device. It is located inside the storage tank 1 and is used to support and measure the liquid level. When the movable component 36 moves in the slide 35, the connected indicator part, such as the index block 361, will move on the scale plate 33 to display the current liquid level. The pressure gauge 31 is fixed at the upper end of the measuring plate 34 and is used to measure the pressure inside the storage tank 1. The alarm 32 is fixed to the right side of the pressure gauge 31. When the liquid level exceeds or falls below the preset safety range, the alarm 32 will issue an alarm signal. The alarm 32 is electrically connected to the display panel 4 through a wire. When the alarm is triggered, the display panel 4 will also display the corresponding alarm information.
[0032] In this embodiment, the movable component 36 includes a slider 362. A capacitor electrode 363 is provided on the right front end of the slider 362. An index block 361 is fixedly connected to the left front end of the slider 362. A float 364 is fixedly connected to the lower end of the slider 362. The slider 362 is movably connected in the groove 35. The index block 361 is located on the front side of the scale plate 33. The float 364 has a spherical structure. The slider 362 is slidably connected in the groove 35.
[0033] Through the above scheme: the float 364 floats up and down in the liquid in the storage tank 1 as the liquid level rises and falls. When the liquid level rises, the float 364 rises as well, and when the liquid level falls, the float 364 falls. The up and down movement of the float 364 is reflected by the sliding of the slider 362 in the slide groove 35. The lower end of the slider 362 is fixedly connected to the float 364, so the movement of the float 364 is directly transmitted to the slider 362. A capacitor plate 363 is provided on the right side of the front end of the slider 362. As the slider 362 slides in the slide groove 35, the relative position between the capacitor plate 363 and other parts fixed on the device, another capacitor plate 363, changes. This change in relative position causes a change in the capacitance value formed between them. The change in capacitance value is then converted into an electrical signal, which represents the current liquid level height.
[0034] It should be noted that this utility model is a remote level transmission device for an alkali storage tank. During use, when the alkali solution enters the storage tank 1 through the inlet pipe 2, the liquid level of the alkali solution will gradually rise. The float 364 floats upward with the rising liquid level, and the float 364 drives the slider 362 to slide upward in the groove 35. Since the indicator block 361 on the left front end of the slider 362 is located in front of the scale plate 33, the liquid level height can be intuitively understood by observing the position change of the indicator block 361 on the scale plate 33. At the same time, as the slider 362 moves, the distance between the capacitor plate 363 on the right front end and the level plate 34 also changes. According to the principle of capacitance, this change in distance will cause a change in capacitance value. Using this characteristic, the change in liquid level height can be converted into an electrical signal. The pressure gauge 31 on the leveling plate 34 can monitor the pressure inside the storage tank 1 in real time. When the pressure changes abnormally, it may indicate that there is an abnormality in the liquid level. When the liquid level reaches or exceeds the set threshold, the alarm 32 will send an alarm signal through the wire electrically connected to the display panel 4 to remind relevant personnel. The entire device converts the physical change of the liquid level into an electrical signal and uses the display panel 4 for remote display and monitoring, realizing the accurate measurement and remote transmission of the liquid level of the alkali storage tank. This allows operators to grasp the liquid level information in a timely manner and take corresponding measures. The pressure at the bottom of the storage tank 1 is detected and converted into liquid level height measurement. Using Archimedes' theorem, the known fatigue density and the measured change are used as the distance change of the capacitor electrode 363 and converted into a standard 420mA signal for transmission to the DCS A card for reception. The signal is then displayed through the monitoring software of the human-machine interface.
