Description

Technical Field

[0001] This utility model relates to the field of molybdenum electrode water-cooling jacket technology, specifically to a top-insertion molybdenum electrode device for a glass electric melting furnace with a safe and intelligent early warning function. Background Technology

[0002] Molybdenum electrode water cooling jackets are key components in high-temperature industrial equipment such as glass electric melting furnaces and electric auxiliary melting furnaces. Their core function is to protect the molybdenum electrode from high-temperature oxidation by circulating cooling water.

[0003] In existing technologies, the water-cooled jackets for molybdenum electrodes typically monitor the electrode temperature in real time using temperature sensors. However, if the water flow rate inside the jacket decreases and this is not detected in time, even if an abnormal temperature is subsequently detected, timely maintenance may not be possible. Therefore, an improvement is needed to address this issue by using a top-inserted molybdenum electrode device for glass electric melting furnaces with a safe and intelligent early warning function. Utility Model Content

[0004] The purpose of this invention is to provide a top-inserted molybdenum electrode device for a glass electric melting furnace with a safe and intelligent early warning function, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a top-inserted molybdenum electrode device for a glass electric melting furnace with a safe and intelligent early warning function, comprising an electrode body, a cooling water jacket fixedly disposed on the outer side of the electrode body, an inlet pipe fixedly disposed on one side of the surface of the cooling water jacket, an outlet pipe fixedly disposed on the surface of the cooling water jacket on one side of the inlet pipe, an ultrasonic probe fixedly disposed at the upper end of the cooling water jacket, and a detection mechanism for detecting the outflow rate disposed inside the outlet pipe, the detection mechanism including a connecting chamber and an impeller, the connecting chamber being fixedly disposed at the upper end of the outlet pipe, and the impeller being movably disposed inside the connecting chamber via a rotating shaft.

[0006] Preferably, both the outlet pipe and the inlet pipe are fixedly equipped with a connecting flange at one end, which allows for easy connection of the outlet pipe and the inlet pipe to other external pipes, and the water jacket to be connected to the regular cooling circuit.

[0007] Preferably, any one of the blades on the impeller surface is made of magnetic material, and a Hall sensor is fixedly installed on the surface of the connecting chamber. The water flow rate detection principle is as follows: after cooling water flows out of the outlet pipe, it drives the impeller to rotate. The faster the water flow rate, the faster the impeller rotates. Since one blade in the impeller is made of magnetic material, a constantly changing magnetic field is generated as the impeller rotates. A Hall sensor is also installed on the outside of the outlet pipe. The Hall sensor can determine the water flow rate through this constantly changing magnetic field. When the water flow rate is below a threshold, the information can be transmitted to the control terminal for the convenience of staff.

[0008] Preferably, the cooling water jacket is uniformly and fixedly provided with several partitions. The partitions can divide the cooling water jacket into several areas, so that the cold water can flow meanderingly inside the cooling water jacket, thereby better exchanging heat with the electrode and removing the heat from the electrode.

[0009] Preferably, the outer surface of the partition has a through hole, through which water can easily flow through the partition to the next area, such as... Figure 5 The image shows an unfolded view of the water jacket. Cooling water enters from the inlet pipe and flows meanderingly under the action of the water jacket and through holes, eventually being discharged from the outlet pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model can monitor the flow rate of the water outlet pipe. When the water flow rate is lower than a threshold, the information can be transmitted to the control terminal so that staff can be notified and an alarm can be triggered before temperature changes occur. This allows staff to formulate maintenance plans in a timely manner and protect the electrodes to the greatest extent.

[0011] 2. In addition, this utility model and device also have a scale detection function. By sending ultrasonic waves into the water jacket through an ultrasonic probe, scale problems can be detected in time, and further, early warnings can be given to detect abnormalities in a timely manner.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a top-inserted molybdenum electrode device for a glass electric melting furnace with a safe and intelligent early warning function, comprising an electrode body 1, a cooling water jacket 2 fixedly disposed on the outer side of the electrode body 1, an inlet pipe 3 fixedly disposed on one side of the surface of the cooling water jacket 2, and an outlet pipe 4 fixedly disposed at a corresponding position on the other side. A connecting flange 8 is fixedly disposed at one end of both the outlet pipe 4 and the inlet pipe 3, allowing for convenient connection of the outlet pipe 4 and the inlet pipe 3 to other external pipes, thus connecting the water jacket to a regular cooling circuit.

[0016] The outlet pipe 4 is equipped with a detection mechanism for detecting the water flow rate. This mechanism includes a connecting chamber 6 and an impeller 7. The connecting chamber 6 is fixedly installed at the upper end of the outlet pipe 4, and the impeller 7 is movably mounted inside the connecting chamber 6 via a rotating shaft. Any one of the blades on the surface of the impeller 7 is made of magnetic material, specifically, a neodymium iron boron permanent magnet may be embedded inside (or a magnetic coating may be used). This allows the impeller 7 to periodically cut the static magnetic field along the axis of the outlet pipe 4 during rotation, forming a pulsating magnetic field signal. The magnetic field strength is proportional to the rotational speed of the impeller 7, and the direction of the magnetic poles alternates with the position of the blades.

[0017] A Hall sensor (such as AH49E) is fixedly mounted on the surface of the connecting chamber 6, with its sensitive surface aligned with the rotation trajectory of the magnetic poles of the impeller 7. The water flow rate detection principle is as follows: After cooling water flows out of the outlet pipe 4, it drives the impeller 7 to rotate. The faster the water flow rate, the faster the impeller 7 rotates. When the magnetic pole is close to the sensor, the output voltage of the Hall element changes linearly with the magnetic field strength; when the magnetic pole moves away, the voltage returns to the baseline value. The Hall sensor can determine the water flow rate through this constantly changing magnetic field. When the water flow rate is below a threshold, the information can be transmitted to the control terminal for timely notification by the staff.

[0018] Several baffles 9 are evenly fixed inside the cooling water jacket 2. These baffles divide the cooling water jacket 2 into several zones, allowing the cold water to flow meanderingly within the jacket, thus improving heat exchange with the electrodes and removing their heat. Through holes 10 are provided on the outer surface of the baffles 9 to facilitate water flow to the next zone. Figure 5 The diagram shows an unfolded view of the water jacket. Cooling water entering from the inlet pipe 3 flows meanderingly under the action of the water jacket and the through hole 10, and finally exits from the outlet pipe 4.

[0019] Scale Thickness Monitoring Principle: This device also features scale thickness monitoring, achieved through an ultrasonic probe 5. The ultrasonic probe 5 is fixedly mounted on the upper end of the cooling water jacket 2. Its working principle is as follows: Ultrasonic waves are sent into the water jacket. The speed of the waves varies significantly depending on the medium as they propagate through scale, metal pipe walls, and cooling water. When the ultrasonic wave encounters the interface between the scale and the pipe wall, some energy is reflected back to the probe, forming the first reflected signal. If the scale layer is thick, the ultrasonic wave may continue to penetrate to the interface between the pipe wall and the cooling water, generating a second reflected signal. The probe determines whether the scale has reached a threshold thickness by receiving the time difference between these reflected signals. If the scale reaches the threshold thickness, it will affect heat transfer and water flow. In this case, the probe transmits an electrical signal to the control terminal, which can detect abnormalities and trigger an alarm before temperature changes, facilitating timely maintenance planning and maximizing electrode protection.
