Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric furnace circulating water safety monitoring technology, and more specifically, to an electric furnace circulating water safety monitoring system. Background Technology
[0002] In modern industrial production, electric furnaces, as a widely used heating device, play a crucial role in many fields such as metal smelting, heat treatment, and chemical industry. During operation, electric furnaces generate a large amount of heat. If this heat cannot be dissipated in a timely and effective manner, it will lead to excessively high internal temperatures, causing a series of serious problems, such as equipment damage, shortened service life, reduced production efficiency, and even safety accidents that endanger the lives and property of personnel. Therefore, in order to ensure the normal operation of electric furnaces, an efficient and reliable cooling system is required, and circulating water cooling system is currently the most widely used cooling method.
[0003] Currently, electric furnace circulating water systems only monitor some key parameters, such as water temperature or water pressure, and cannot fully and in real time grasp the status of circulating water. For example, in the electric furnace workshops of some small enterprises, only a simple thermometer is installed at the inlet of the circulating water, and operators can only roughly understand the water temperature by checking the thermometer periodically.
[0004] This monitoring method not only fails to detect rapid changes in water temperature in a timely manner, but also remains completely unaware of other important parameters such as water quality and flow rate. Furthermore, it cannot monitor water quality, as impurities and changes in pH levels in the water can lead to pipe corrosion and scaling, thereby affecting the circulation and cooling effect of the circulating water. If blockages or leaks occur in the pipes and are not detected and dealt with in a timely manner, the electric furnace will not be cooled sufficiently, causing overheating and damage to the equipment. Therefore, a safety monitoring system for electric furnace circulating water is proposed. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electric furnace circulating water safety monitoring system to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric furnace circulating water safety monitoring system, comprising a housing, with an inlet pipe and an outlet pipe running through the middle of the housing. The inlet pipe is responsible for transporting water cooled by the heat exchanger tank to the electric furnace cooling water pipe, while the outlet pipe returns the water that has absorbed heat from the electric furnace to the heat exchanger tank for cooling, forming a circulating water flow loop. A control host, a first temperature sensor, and a humidity sensor are installed at the top of the inner cavity of the housing. The control host is responsible for receiving, processing, and analyzing data from each sensor. The first temperature sensor is used to monitor the internal temperature of the housing to prevent overheating due to internal temperature issues. Excessive humidity can affect the normal operation of the equipment. A humidity sensor monitors the humidity inside the enclosure to prevent electrical components from being damaged by moisture. The front of the enclosure has an inspection door and a control panel, while the top is equipped with an alarm, a transceiver, and an alarm light. The inspection door facilitates easy access for maintenance. The alarm sounds an audible alert when abnormal circulating water parameters are detected, alerting operators. The transceiver communicates with external devices, such as transmitting monitoring data to a remote monitoring center or receiving remote control commands. The alarm light flashes in abnormal situations to draw operators' attention more directly.
[0007] The top of the water inlet pipe is equipped with a first pressure sensor, a first flow sensor, a second temperature sensor, and a water quality sensor. The first pressure sensor monitors the water pressure inside the inlet pipe to ensure stable inlet pressure and prevent excessively high or low pressure from affecting the cooling effect of the electric furnace. The first flow sensor measures the water flow rate inside the inlet pipe to ensure sufficient water enters the electric furnace cooling water pipe. The second temperature sensor monitors the temperature of the inlet water in real time to detect abnormal water temperatures promptly. The water quality sensor detects the quality of the inlet water, such as pH and impurity content, to prevent corrosion or blockage of the electric furnace due to water quality issues. The top of the water outlet pipe is equipped with a second flow sensor and a second pressure sensor. The second flow sensor monitors the water flow rate inside the outlet pipe and compares it with the flow rate data from the inlet pipe to determine if there are any leaks or other problems in the circulating water system. The second pressure sensor detects the water pressure inside the outlet pipe to ensure normal return water pressure.
[0008] Preferably, an inspection port is provided on the front side of the enclosure corresponding to the inspection door. One side of the inspection door is rotatably connected to the enclosure, and a lock body is provided on one side of the inspection door. A handle is fixedly connected to the end of the inspection door near the control panel. The lock body can prevent unauthorized personnel from opening the inspection door at will, and facilitate operators to open the inspection door to inspect and maintain the equipment inside the enclosure.
[0009] Preferably, the control panel and the control host are electrically connected, and the control host is electrically connected to the alarm, signal transceiver, and alarm light. Operators can input commands to the control host through the control panel to set monitoring parameters and alarm thresholds, etc.
[0010] Preferably, the first pressure sensor, the first flow sensor, the second temperature sensor, the water quality sensor, the second flow sensor, and the second pressure sensor are all electrically connected to the control host to facilitate receiving monitoring data and transmitting the data they monitor to the control host for processing in real time.
[0011] Preferably, the first pressure sensor, the first flow sensor, the second temperature sensor, the water quality sensor, the second flow sensor, and the second pressure sensor are all located in the middle of the housing for easy maintenance and protection.
[0012] Preferably, the bottom of the inner cavity of the box is provided with multiple hydraulic jacks, the output end of which is connected to a stabilizing top plate. The top walls of the multiple stabilizing top plates are respectively attached to the bottom walls of the inlet pipe and the outlet pipe. The hydraulic jacks can adjust the height of the stabilizing top plates as needed to provide stable support for the inlet pipe and the outlet pipe, reduce the shaking of the pipe caused by water flow impact or external vibration, and ensure the stability and sealing of the pipe connection.
[0013] Preferably, the output end of the inlet pipe is connected to the electric furnace cooling water pipe, the input end of the inlet pipe is connected to the hot water exchange tank, the output end of the outlet pipe is connected to the hot water exchange tank, and the input end of the outlet pipe is connected to the electric furnace cooling water pipe, which facilitates monitoring and improves the safety of the circulating water.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. This utility model firstly uses a first pressure sensor on the water inlet pipe to monitor the water pressure inside the pipe, ensuring stable water pressure. A first flow sensor is used to measure the water flow rate inside the pipe. A second temperature sensor monitors the water temperature in real time. A water quality sensor detects the water quality to prevent corrosion or blockage of the electric furnace due to water quality issues. By setting multiple sensors, the temperature, pressure, flow rate, and water quality parameters of the circulating water can be monitored accurately and in real time, allowing for timely detection of potential problems and ensuring the safe operation of the electric furnace. Furthermore, the inclusion of alarms, alarm lights, and a signal transceiver enables timely alerts when abnormal conditions are detected, facilitating prompt action by operators and reducing the occurrence of accidents.
[0016] 2. This utility model also uses a first temperature sensor inside the box to monitor the internal temperature of the box, preventing the equipment from operating normally due to excessive internal temperature; a humidity sensor is used to monitor the internal humidity of the box, preventing electrical components from being damaged by moisture due to excessive humidity; and the hydraulic top and stabilizing top plate provide stable support for the inlet and outlet pipes, reducing pipe shaking and improving the stability and reliability of the entire system.
