Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment equipment technology, and in particular to a device for monitoring the operating status of waste gas treatment facilities. Background Technology

[0002] Waste gas treatment facilities are crucial equipment in industrial production for purifying harmful gases. They are widely used in chemical, metallurgical, pharmaceutical, and spraying industries to reduce pollutant emissions and protect the ecological environment. Common waste gas treatment methods include spray scrubbing, activated carbon adsorption, and catalytic combustion, with the final treated gases discharged into the atmosphere through exhaust pipes. In actual operation, the operational status of waste gas treatment facilities directly affects the treatment effect and emission compliance. If the equipment shuts down, becomes blocked, or the fan malfunctions, waste gas may be discharged without adequate treatment, leading to excessive pollutant levels and even safety hazards. Therefore, real-time monitoring of the operational status of waste gas treatment facilities is essential.

[0003] However, existing monitoring technologies mostly rely on electronic sensors, control circuits, or PLC systems for status feedback. These systems are costly, complex to maintain, and exhibit poor stability in high-temperature, high-humidity, or highly corrosive industrial environments, posing a risk of false alarms or malfunctions. Some simple devices even lack operational status indicators, relying solely on manual experience for judgment, which leads to detection delays or inaccurate assessments. Therefore, developing a simple, power-free mechanical monitoring device that can directly reflect the operational status of the waste gas treatment system has significant practical value and potential for widespread application. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a monitoring device for the operation status of waste gas treatment facilities, so as to solve the problems of complex structure, high cost and insufficient visual feedback of existing monitoring devices.

[0005] To achieve the above objectives, this utility model provides a monitoring device for the operation status of a waste gas treatment facility, including an exhaust pipe, a drive assembly, and a display assembly.

[0006] A drive assembly, located inside the exhaust pipe, is used to utilize and guide the exhaust gas discharged from inside the exhaust pipe, providing a kinetic energy basis for the display assembly.

[0007] The display component is located on one side of the exhaust pipe and is used in conjunction with the drive component to monitor the working status of the exhaust gas treatment facility and provide an intuitive and real-time display.

[0008] Preferably, the drive assembly includes a turbofan, which is rotatably mounted inside the exhaust pipe. A toothed ring is fixedly mounted on the outside of the turbofan, and a limiting ring is fixedly mounted on the toothed ring. A groove is formed inside the exhaust pipe, and the limiting ring is slidably mounted in the groove inside the exhaust pipe.

[0009] Preferably, the display component includes a gear meshing with one side of the gear ring. A first color plate is fixedly installed below the gear. A plurality of grooves are evenly provided on the first color plate. A second color plate is slidably installed on the grooves. A spring is fixedly installed on one side of the second color plate. The other end of the spring is fixedly connected to the middle of the first color plate.

[0010] Preferably, a first protective shell is fixedly installed on the outer side of the gear ring, and a second protective shell is fixedly installed on the outer side of the gear. The gear is rotatably installed inside the second protective shell. An observation window is provided below the second protective shell.

[0014] Preferably, the first color swatch and the second color swatch are two different color swatches.

[0015] The beneficial effects of this utility model are:

[0016] 1. The waste gas treatment facility operation status monitoring device adopts a turbofan structure as a passive power acquisition component, and works with a limit ring and a toothed ring structure for stable guidance and power transmission. This allows the monitoring system to be automatically driven during the waste gas discharge process. It has the advantages of simple structure, sensitive response, convenient installation, and no maintenance required for long-term operation. It is suitable for various industrial waste gas treatment scenarios, and performs particularly well in situations where there is a lack of power supply or unstable electrical control.

[0017] 2. This waste gas treatment facility operation status monitoring device achieves automatic color switching under wind speed changes through the centrifugal sliding and spring reset principle between color plates. Combined with the transparent observation window structure, it allows operators to intuitively judge the operation status of the waste gas treatment device without disassembly or testing, significantly improving inspection efficiency and safety assurance capabilities, avoiding missed detections and delays due to operational anomalies, and has good prospects for industrial application.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 5 As shown, a waste gas treatment facility operation status monitoring device includes an exhaust pipe 3, a drive assembly, and a display assembly. The side of the exhaust pipe 3 away from the first protective shell 5 is connected to a gas transmission pipe 2, and the other side of the gas transmission pipe 2 is connected to a treatment tank 1. A fixing frame 4 is fixedly installed on the exhaust pipe 3, and the fixing frame 4 is located on both sides of the first protective shell 5 on the exhaust pipe 3. The connection design between the exhaust pipe 3, the gas transmission pipe 2, and the treatment tank 1 ensures that the waste gas flows stably from the treatment tank 1 into the exhaust pipe 3 through the gas transmission pipe 2, realizing the integration of continuous waste gas guidance and detection, and facilitating the formation of a stable power source.

[0029] Furthermore, such as Figures 1 to 4As shown, the drive assembly, located inside the exhaust pipe 3, utilizes and guides the exhaust gas discharged from the exhaust pipe 3 to provide the kinetic energy foundation for the display components. It includes a turbofan 8, which is rotatably mounted inside the exhaust pipe 3. A gear ring 9 is fixedly mounted on the outside of the turbofan 8, and a limit ring 10 is fixedly mounted on the gear ring 9. A groove is formed inside the exhaust pipe 3, and the limit ring 10 is slidably mounted in the groove inside the exhaust pipe 3. A first protective shell 5 is fixedly mounted on the outside of the gear ring 9, providing protection for the gear ring 9. The first protective shell 5 does not contact the gear ring 9. The turbofan 8, installed inside the exhaust pipe 3, is directly driven by the flow of exhaust gas, requiring no additional energy, achieving passive drive, significantly improving the energy efficiency and ease of installation of the structure, and adapting to various industrial sites. The gear ring 9 is fixedly connected to the turbofan 8, serving as a power output device, and can stably drive the external display components, facilitating external speed synchronization feedback, reducing the risk of slippage or slippage of the gear 11, and improving the reliability of system response. The limit ring 10 is slidably mounted in the groove inside the exhaust pipe 3. Inside the groove, the toothed ring 9 is radially limited and its position stabilized, preventing axial or radial displacement of the turbine fan 8 during operation and ensuring long-term mechanical precision. The first protective shell 5 covers the toothed ring 9 but does not contact it, effectively preventing dust, oil, or corrosive gases from directly eroding the toothed ring 9 and improving the service life of the entire structure. The fixing frame 4 is installed on the exhaust pipe 3 and located on both sides of the first protective shell 5, providing a stable support foundation for the entire drive and display system. When the monitoring device is in use, the exhaust gas first enters the treatment tank 1, undergoes necessary purification or treatment, and is then transported to the exhaust pipe 3 through the gas supply pipe 2. The exhaust gas flows in the exhaust pipe 3, driving the turbine fan 8 installed inside the exhaust pipe 3 to rotate. The rotation of the turbine fan 8 is converted into mechanical kinetic energy, which is the power source of the entire monitoring device. The toothed ring 9 is fixedly connected to the outside of the turbine fan 8. When the turbine fan 8 rotates, it drives the toothed ring 9 to rotate synchronously. The limiting ring 10 is installed in the groove inside the exhaust pipe 3 to constrain the movement trajectory of the toothed ring 9 and ensure its stable rotation. The rotation of the toothed ring 9 can be transmitted to the display components by meshing with the external pinion 11.

[0030] Furthermore, such as Figures 1 to 5As shown, the display component, located on one side of the exhaust pipe 3, is used to monitor and display the working status of the exhaust gas treatment facility in a direct and real-time manner in conjunction with the drive component. It includes a gear 11, which is meshed with one side of the gear ring 9. A first color plate 12 is fixedly installed below the gear 11. Multiple grooves 15 are evenly distributed on the first color plate 12, and a second color plate 13 is slidably installed on the grooves 15. A spring 14 is fixedly installed on one side of the second color plate 13, and the other end of the spring 14 is fixedly connected to the middle of the first color plate 12. A second protective shell 6 is fixedly installed on the outside of the gear 11, and the gear 11 is rotatably installed inside the second protective shell 6. An observation window 7 is provided below the second protective shell 6. The first protective shell 5 and the second protective shell 6... The first protective shell 5 and the second protective shell 6 are both fixedly installed on the exhaust pipe 3. The gear 11 is rotatably installed inside the second protective shell 6. The first color plate 12 and the second color plate 13 are two different colors, where the first color plate 12 can be red and the second color plate 13 can be green. The gear 11 is installed on one side of the exhaust pipe 3 and meshes with the gear ring 9, which can accurately and synchronously obtain the speed information of the turbofan 8, ensuring that the display component reflects the actual exhaust state. When the gear 11 drives the first color plate 12 to rotate at high speed, the centrifugal force drives the second color plate 13 to slide outward in the slide groove 15, exposing the green second color plate 13. If the speed decreases, the spring 14 pulls the second color plate 13 back, exposing the red first color plate 12, realizing the wind speed / movement... The automated color-coded warning system switches between operating states. Spring 14 connects the second color plate 13 to the middle of the first color plate 12, automatically pulling the outwardly sliding second color plate 13 back to its original position. The structure automatically restores itself when the wind speed decreases or the equipment stops. The reset function is purely mechanical, requiring no electrical control system. An observation window 7 is located below the second protective shell 6, allowing users to directly observe the current displayed color and quickly determine the operating status of the exhaust gas treatment facility (e.g., green = normal, red = abnormal), improving the intuitiveness of the device and inspection efficiency. The gear 11 transmission is fully enclosed and internally continuous, contributing to the overall sealing and consistency of the structure. During use, the exhaust gas treated by the treatment tank 1 and the gas delivery pipe 2 enters the exhaust pipe 3, driving the internal turbine fan 8 to rotate. When the turbine fan 8 rotates, the gear ring 9 fixed on its outer side rotates synchronously. The gear ring 9 meshes with the external gear 11. The rotation speed of the turbine fan 8 is transmitted to the display component through the gear 11. The rotation of the gear 11 drives the first color plate 12 fixedly connected to it to rotate synchronously. Multiple grooves 15 evenly distributed on the first color plate 12 begin to generate centrifugal effect. As the rotation speed increases, the second color plate 13 in the groove 15 slides outward under the action of centrifugal force. After sliding outward, the second color plate 13 (green) that was originally covered is gradually revealed, covering the first color plate 12 (red), forming a visual color switch. Users can see the currently displayed color through the observation window 7 below the second protective shell 6. If green is displayed, it means that the exhaust gas wind speed is normal and the treatment equipment is operating well.If the color is red, it may indicate that the equipment has stopped or that some processes are malfunctioning. When the exhaust gas flow rate decreases and the turbine fan 8 speed slows down, the centrifugal force decreases, and the spring 14 pulls the second color plate 13 back to the center position of the slide 15, causing the first red color plate 12 to be exposed again, indicating an abnormal operation or a shutdown status.
