Technical Field

[0001] This application relates to the field of flow monitoring technology for electric furnaces, and more particularly to a flow monitoring device for electric furnaces. Background Technology

[0002] An electric furnace flow meter is a device used to measure the flow rate of fluids (such as gases or liquids) within an electric furnace. In an electric furnace, fluid flow rate is crucial for temperature control, ensuring process stability, and product quality. Therefore, using an electric furnace flow meter enables precise flow measurement and control, thereby improving furnace efficiency and production process reliability.

[0003] There are many different principles and types of flow meters used in electric furnaces. Common types include differential pressure flow meters, vortex flow meters, and electromagnetic flow meters. Each of these flow meters has its own characteristics and applicable range. When selecting and using them, it is necessary to take into account the specific process requirements and fluid characteristics.

[0004] Existing electric furnace flow meters cannot automatically alarm and shut down in a timely manner when the fluid flow is abnormal, and are inconvenient for staff to remotely control and adjust during use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a flow monitoring device for electric furnaces, which overcomes the deficiencies of existing technologies and aims to solve the problems that existing electric furnace flow meters cannot automatically alarm and shut down in a timely manner when the fluid flow is abnormal, and are inconvenient for operators to remotely control and adjust during use.

[0006] To achieve the above objectives, this application provides the following technical solution: a flow monitoring device for an electric furnace, comprising a mixing box, a controller and a signal processor installed inside the mixing box, an electric furnace tube disposed on one side of the mixing box, a flow monitoring mechanism disposed on the outside of the electric furnace tube, the flow monitoring mechanism being sleeved on the outside of the electric furnace tube, the detection end of the flow monitoring mechanism penetrating the inner wall of the electric furnace tube and located inside the electric furnace tube, the flow monitoring mechanism comprising a flow monitor and a data panel, an installation groove being provided on one side of the flow monitor, the data panel being installed inside the installation groove, a display panel being provided on one side of the data panel, and the flow monitoring mechanism, the controller, the display panel, the signal processor, the data panel and the electric furnace being electrically connected.

[0007] By adopting the above technical solution and setting up a flow monitoring mechanism, the flow monitor can monitor the flow velocity inside the electric furnace tube in real time during use. The signal processor processes and analyzes the flow signal, and the controller determines whether the current flow is abnormal based on the preset flow threshold. If an abnormality is found, the electric furnace will automatically shut down. At the same time, the signal processor and controller can also be remotely debugged by the staff. This setup can react quickly when the fluid flow is abnormal, shut down the furnace in time, and notify the operators, thereby effectively avoiding equipment damage and production accidents, and improving the safety and production efficiency of the electric furnace. Meanwhile, the addition of remote monitoring and debugging functions further reduces the difficulty of operation and maintenance costs.

[0008] As a preferred embodiment of this application, the control valve is installed on the outside of the electric furnace tube, the control valve is located above the flow monitoring mechanism, and the control valve is electrically connected to both the controller and the flow monitoring mechanism.

This setup makes the device more accurate and has a wider coverage when detecting the internal flow rate of the electric furnace tube, which is more conducive to the analysis of abnormal flow rates by the staff.

[0012] As a preferred technical solution of this application, the flow monitor has sliding grooves on both sides near the mounting groove, and sliding blocks are slidably connected inside the sliding grooves on both sides. Movable plates are installed on the outer sides of the two sets of sliding blocks, and protective covers are fixedly connected to the other ends of the two sets of movable plates.

[0014] As a preferred technical solution of this application, a buzzer alarm is installed on one side of the flow monitor, and the buzzer alarm is electrically connected to the data panel.

[0015] By adopting the above technical solution and setting up a buzzer alarm, the device can promptly emit a sound to remind on-site staff when abnormal flow is detected, thus improving the device's practicality.

[0016] As a preferred technical solution of this application, an indicator light is provided on one side of the data panel, the indicator light is located above the display panel, and the indicator light is electrically connected to the flow monitor and the data panel.

[0018] As a preferred technical solution of this application, the protective cover is made of transparent acrylic material, and the outer side of the protective cover is coated with a hydrophobic coating.

[0019] By adopting the above technical solution and setting the protective cover to be made of transparent acrylic material, staff can observe the readings of the display panel without opening the protective cover. The hydrophobic coating can prevent liquid from remaining on the surface of the protective cover and affecting normal observation.

[0020] As a preferred embodiment of this application, the size of the two sets of sliding blocks is the same as the size of the sliding groove, and the size of the mounting groove is the same as the size of the data panel.

[0021] By adopting the above technical solution, and by setting the size of the two sets of sliding blocks to be the same as the size of the sliding groove, and the size of the mounting groove to be the same as the size of the data panel, the device can be made more stable during installation and operation, preventing shaking.
