Description

Technical Field

[0001] This utility model belongs to the field of polymerization production and relates to a device for timely monitoring of the actual liquid level of key equipment to prevent tank overflow. Background Technology

[0002] The polymerization workshop contains a variety of volatile, scale-forming, and highly viscous materials, as well as powders. Due to their inherent characteristics, the volatility of these materials can interfere with the level gauge readings. Scale-forming and highly viscous substances can adhere to the instruments, leading to inaccurate level displays. Furthermore, the varying angles of the powders due to their stacking can also cause inaccurate level readings. Therefore, in addition to the central control personnel in the DCS room monitoring the tank levels of these materials in real time, on-site operators also need to periodically check whether the actual levels deviate from the specified values.

[0003] In addition, during abnormal operating conditions, the liquid level may be too high, and on-site personnel need to check the liquid level in a timely manner and report it to the central control computer to see if the liquid level is too high. In many polymerization plants, there have been cases of material overflow and pipeline blockage caused by untimely understanding and handling of liquid level conditions.

[0004] In response to the above situation, the existing method for important, critical storage tanks where level gauges are prone to inaccuracy is mainly to communicate between central control personnel and on-site personnel via walkie-talkie. When an abnormal level is detected, the on-site personnel are notified to go to the location of the equipment to check the level in person. This method has the following two drawbacks: (1) It is not timely enough. It is necessary to communicate via walkie-talkie first, identify the designated personnel, and then go to the location of the equipment to check in person. It is also affected by the enthusiasm of the personnel, and in emergency situations, it is impossible to report the level in time, resulting in adverse results. (2) Everyone's angle and description of the level will be different. The feedback from different shifts is also affected by subjective judgment. The long-term level difference caused by this may lead to changes in the material retention reaction time, thereby causing deviations in product quality. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a device for timely monitoring of the actual liquid level of key equipment to prevent overflow. The device uses lighting, mirrors and reference units to reflect the liquid level image, and then uses a camera to feed the image back to the central control computer. This solves the problem of untimely and inaccurate liquid level feedback of key equipment, which leads to material overflow and pipeline blockage.

Adopting this invention reduces on-site personnel activity and enhances the central control capabilities of the DCS room; it also provides timeliness in emergencies, allowing for quick and simple understanding of the actual liquid level; and it prevents tank overflows and production shutdowns in abnormal operating conditions.

Figure 1 As shown, it includes a central control computer 1, a real-time video control cabinet 2, a DCS control cabinet 3, a camera 4, a lighting lamp 5, a first side mirror 6, a second side mirror 7, a reference unit 8, an equipment storage tank 9, and a power box 10.

[0031] The central control computer 1 is electrically connected to the real-time video control cabinet 2, and the central control computer 1 is electrically connected to the DCS control cabinet 3;

[0032] The DCS control cabinet 3 is equipped with a lighting switch button 301;

[0033] The central control computer 1 is connected to the real-time video control cabinet 2 and the DCS control cabinet 3 via cables;

[0034] The real-time video control cabinet 2 is electrically connected to the camera 4, and the DCS control cabinet 3 is electrically connected to the lighting lamp 5;

[0035] The real-time video control cabinet 2 is connected to the camera 4 via a cable, and the DCS control cabinet 3 is connected to the lighting lamp 5 via a cable;

[0036] The camera 4 is a high-definition camera;

[0037] The power box 10 is connected to the lighting lamp 5;

[0038] The lighting lamp 5 is a high-intensity lamp. The switching signal of the lighting lamp 5 is controlled by the lighting lamp switch button 301 of the DCS control cabinet 3 to avoid the lamp from overheating due to long-term illumination, which could cause the sight glass or lamp to break.

[0039] The first side mirror 6 and the second side mirror 7 are disposed at both ends of the top of the equipment storage tank 9;

[0040] The first side mirror 6 and the second side mirror 7 are glass mirrors;

[0041] The reference unit 8 is disposed inside the equipment storage tank 9;

[0042] The camera 4 is located at the first side mirror 6 and is used to capture the image inside the first side mirror 6.

[0043] The lighting lamp 5 is located at the second side mirror 7, and the lighting lamp 5 is used to illuminate the material inside the equipment storage tank 9 and the position of the reference unit 8.

[0044] The reference unit 8, lighting lamp 5, and camera 4 are set at different heights, and their heights are adjusted to accommodate different devices on site.

[0045] The illumination angle of the lighting lamp 5 covers the reference unit 8, and the visible range of the first side mirror 6 and the second side mirror 7 covers the reference unit 8.

[0046] The placement angles of the first side mirror 6 and the second side mirror 7 were adjusted on-site to fully cover the reference unit 8 and to ensure that the camera 4 would not reflect light or be unclear during monitoring.

[0047] like Figure 2 As shown, the reference unit 8 is a cylindrical structure with circular holes 801 evenly distributed from top to bottom. The operator can confirm the liquid level height by counting the number of holes.

[0048] In use, the central control computer 1, real-time video control cabinet 2, and DCS control cabinet 3 are arranged in the central control room, while the camera 4, lighting 5, first side mirror 6, second side mirror 7, reference unit 8, equipment storage tank 9, and power box 10 are arranged in the workshop.

[0049] First, adjust the side mirrors. This invention can be equipped with 2-3 side mirrors as needed. This embodiment takes two side mirrors as an example, that is... Figure 1 The first side mirror 6 and the second side mirror 7 are shown.

[0050] Secondly, the structure of the reference unit 8 is prepared in advance inside the equipment storage tank 9, and the height of the reference unit 8, the lighting lamp 5, and the camera 4 are adjusted according to the size and height of the equipment.

[0051] The orientation of the viewing mirrors should be such that they fully cover all reference units 8. Two of the viewing mirrors are arranged such that one side is a viewing mirror with a high-definition camera, namely the first viewing mirror 6 equipped with a camera 4; the other side is a viewing mirror with a high-intensity light, namely the second viewing mirror 7 equipped with a lighting lamp 5.

[0052] The power signal for the lighting lamp 5 is provided by the power box 10, and the switch signal is provided by the DCS control cabinet 3.

[0053] When this utility model is implemented, the material inside the equipment storage tank 9 is illuminated by the lighting lamp 5 through the second side mirror 7, and the camera 4 transmits the situation inside the equipment storage tank 1 illuminated by the first side mirror 6 back to the central control room so that the operator can view it.

[0054] The video signal is transmitted from the camera 4 in the workshop to the real-time video control cabinet 2 via a signal line. The real-time video control cabinet 2 then communicates with the central control computer 1 in the central control room to synchronize the real-time image of the camera 4.

[0055] The DCS control cabinet 3 is equipped with a lighting switch button 301. The central control computer 1 is operated by personnel or program. The DO signal is issued by the central control computer 1 and transmitted to the DCS control cabinet 3. The DCS control cabinet 3 then transmits the switch signal to the lighting 5 in the workshop through the signal line.

[0056] Two signal lines are connected from the field to the central control room via cables;

[0057] When the central control operator needs to check the material level, they can turn on the lighting switch button 301 of the DCS control cabinet 3. The digital signal will turn on the lighting lamp 5 through the cable. At the same time, the operator can also pick up the corresponding screen on the central control computer 1 for real-time monitoring to check the liquid level on site.
