Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell safety technology, and more specifically, to an alarm device for the long angle of the anode of an electrolytic cell and a lifting device structure. Background Technology

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode, with most separating the anode and cathode chambers by a diaphragm. Based on the electrolyte, they are classified into three types: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface, to produce the desired product.

[0003] As the electrolytic cell ages, the carbon blocks on the anode gradually wear down. The distance between the anode carbon blocks and the aluminum horizontal plane is constant. If the carbon blocks are worn down, the anode must be lowered to maintain this distance. At this point, the electrolytic cell control unit automatically operates the screw jack to lower the horizontal busbar and the anode carbon blocks based on the voltage. Furthermore, due to temperature variations, electrolyte agglomerates and deposits at the corners of the anode, pressing against the bottom of the electrolytic cell and between the anode carbon blocks. This causes the anode to develop an elongated angle, turning the force of the screw jack's descent into a reaction force. Over time, the base of the screw jack will break, causing equipment damage. In severe cases, other anodes will slide down, expelling electrolyte and molten aluminum, breaking the cell's surrounding busbar, leading to a major accident, affecting the safety of the electrolytic cell, and resulting in a lack of anodes. The safety warning structure for extremely long corners is problematic. Meanwhile, invention patent CN114990593A discloses a device to prevent extremely long corners at the anode, including an electrolytic cell and an electrolytic cell flue. The electrolytic cell flue is fixedly connected to the top of the electrolytic cell. An electric valve is installed in the middle of the outer surface of the electrolytic cell flue. The electric valve includes a controller, a valve stem, a handle, a rotating rod, a valve plate, and a sealing plate. The controller is installed in the middle of the outer surface of the valve stem, the handle is fixedly connected to the outer surface of the valve stem, the rotating rod is fixedly connected to the bottom of the valve stem, the valve plate is fixedly connected to the end of the rotating rod away from the valve stem, and the sealing plate is fixedly installed on the inner wall of the electrolytic cell flue. However, this device is not convenient for issuing an alarm when the anode is at an extremely long corner, and its safety performance needs improvement. Utility Model Content

[0004] To overcome the problems of existing technologies where anodes develop elongated angles with increasing cell age, which can lead to damage to the screw jack if not detected in time during aluminum tapping, affecting the stable operation of the electrolytic cell, and in severe cases, causing multiple anodes to fall into the cell and force out electrolyte and molten aluminum, thus compromising cell safety, and lacking a safety warning structure for anode elongation, this utility model provides an anode elongation alarm device for electrolytic cells. The device includes a monitoring box and a safety warning component. The monitoring box is installed on the upper crossbeam of the electrolytic cell, and the safety warning component includes an audible and visual alarm and a limit switch. The audible and visual alarm is installed on the top of the monitoring box, and the limit switch is installed inside the monitoring box. The detection end of the limit switch is connected to the top of the screw jack of the electrolytic cell.

[0005] Installing the monitoring box next to the screw jack allows for limit monitoring of the upper position of the screw jack via limit switches. After the anode angle is extended, the screw jack encounters resistance during the lowering of the busbar and is subjected to upward lifting resistance. When the entire screw jack is lifted upward, it shifts upward, triggering the limit switches and controlling the audible and visual alarm to sound an alarm, reminding staff to handle the situation promptly and preventing damage to the screw jack after prolonged lifting. This greatly improves the practicality of the entire alarm device.

[0006] Preferably, the limit switch is a mechanical limit switch, and the trigger end of the limit switch is connected to a trigger plate, which is placed horizontally on the upper surface of the screw jack.

[0007] Preferably, a controller is installed inside the monitoring box, and the audible and visual alarm is electrically connected to the limit switch through the controller.

[0008] Preferably, a signal transmitting module is installed inside the monitoring box. The input terminal of the signal transmitting module is electrically connected to the controller, and the output terminal of the signal transmitting module is signal connected to an external control host.

[0009] By using a signal transmission module installed inside the monitoring box, the displacement information of the screw crane can be collected by the limit switch and transmitted to the external control host. This allows staff to be alerted by the external warning light structure, further improving the convenience of the device.

[0010] Preferably, the monitoring box is equipped with a protective reinforcing plate on the outside and an insulating plate on the inside.

[0011] The protective reinforcement plate installed on the outside of the monitoring box can improve the overall strength of the monitoring box, enhance its pressure resistance, and make it less prone to damage. The insulation plate installed inside the monitoring box can prevent leakage of current and also prevent electrostatic interference, thus improving the stability of the monitoring box operation.

[0012] Preferably, the monitoring box has an inspection door hinged to its front, and the surface of the inspection door is provided with an observation window.

[0013] Preferably, the outer surface of the monitoring box has a number of small heat dissipation holes.

[0014] Preferably, the monitoring box is equipped with several fixed side plates, and each fixed side plate has several fixing holes.

[0015] Preferably, the present invention also provides a lifting device structure, including a screw lifter and an alarm device as described in any one of the claims, wherein the alarm device is connected to the top of the screw lifter, and a busbar connecting plate that can be connected to the horizontal busbar of the electrolytic cell is provided at the bottom movable end of the screw lifter.

[0016] Preferably, the screw jack is bolted to the upper beam of the electrolytic cell, and a spring washer is provided between the bolt and the base of the screw jack.

[0017] A buffer space can be formed between the fixing bolt and the screw jack by using spring washers.

[0018] Beneficial effects:

[0019] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0020] (1) Install the monitoring box next to the screw jack. The upper position of the screw jack can be monitored by the limit switch. After the anode angle is extended, the screw jack is blocked during the process of lowering the busbar and is subjected to the resistance of being lifted upward. When the screw jack is lifted upward as a whole, it will shift upward, thereby triggering the limit switch and controlling the sound and light alarm to sound an alarm, reminding the staff to deal with it in time, avoiding damage to the screw jack after being lifted for a long time, and greatly improving the practicality of the entire alarm device.

[0021] (2) By using the signal transmission module installed inside the monitoring box, the information can be transmitted to the external control host after the limit switch collects the displacement information of the screw jack. This allows the staff to be reminded through the external warning light structure, further improving the convenience of the device.

[0022] (3) By installing a protective reinforcing plate on the outside of the monitoring box, the overall strength of the monitoring box can be improved, its pressure resistance can be enhanced, and it is not easy to be damaged. By installing an insulating plate inside the monitoring box, leakage of the monitoring box can be avoided. At the same time, it can also prevent static interference and improve the stability of the monitoring box operation. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] This embodiment installs the monitoring box next to the screw jack, allowing for limit switch monitoring of the upper position of the screw jack. After the anode angle is extended, the screw jack encounters resistance during the lowering of the busbar and is subjected to upward lifting resistance. When the entire screw jack is lifted upward, it shifts upward, triggering the limit switch and controlling the audible and visual alarm to sound, alerting staff to handle the situation promptly and preventing damage to the screw jack after prolonged lifting. This significantly improves the practicality of the entire alarm device. The specific implementation method is as follows:

[0031] like Figures 1 to 4 As shown, an alarm device for anode elongation at an electrolytic cell includes a monitoring box 2 and a safety warning component. The monitoring box 2 is installed on the upper crossbeam of the electrolytic cell. The safety warning component, including an audible and visual alarm 5 and a limit switch 11, is mounted on the monitoring box 2. The limit switch 11 is installed inside the monitoring box 2, and its detection end is connected to the top of the screw jack 1 of the electrolytic cell. By installing the monitoring box 2 next to the screw jack 1, the upper position of the screw jack 1 can be monitored by the limit switch 11. After the anode elongates at an angle, the screw jack 1 is obstructed during the lowering of the busbar and experiences upward resistance. When the screw jack 1 is lifted upwards, it shifts upwards, triggering the limit switch 11 and controlling the audible and visual alarm 5 to sound an alarm, reminding staff to handle the situation promptly and preventing damage to the screw jack 1 after prolonged lifting. This greatly improves the practicality of the entire alarm device.

[0032] Limit switch 11 is a mechanical limit switch. The trigger end of limit switch 11 is connected to trigger plate 4, which is placed horizontally on the upper surface of screw jack 1. Limit switch 11 is connected to the upper surface of screw jack 1 through trigger plate 4. When screw jack 1 is lifted upward by a long angle, limit switch 11 is triggered by trigger plate 4.

[0033] The monitoring box 2 is equipped with a controller 9. The audible and visual alarm 5 is electrically connected to the limit switch 11 through the controller 9. Under the action of the controller 9, the audible and visual alarm 5 can be controlled in conjunction with the limit switch 11 to achieve sound and light warning.

[0034] The monitoring box 2 is equipped with a signal transmission module 10. The input terminal of the signal transmission module 10 is electrically connected to the controller 9, and the output terminal of the signal transmission module 10 is connected to the external control host. Through the signal transmission module 10 installed inside the monitoring box 2, after the limit switch 11 collects the displacement information of the screw crane 1, the information is transmitted to the external control host, thus allowing staff to be alerted via the external warning light structure, further improving the convenience of the device.

[0035] The monitoring box 2 is equipped with a protective reinforcing plate 13 on its exterior and an insulating plate 12 on its interior. The protective reinforcing plate 13 installed on the exterior of the monitoring box 2 can improve the overall strength of the monitoring box 2, enhance its pressure resistance, and make it less prone to damage. The insulating plate 12 installed inside the monitoring box 2 can prevent leakage of current and also prevent electrostatic interference, thus improving the stability of the monitoring box operation.

[0036] The monitoring box 2 has a maintenance door 8 hinged to its front, and the surface of the maintenance door 8 is provided with an observation window. By opening the maintenance door 8, it is convenient to inspect and maintain the internal components of the monitoring box 2.

[0037] Several small ventilation holes are formed on the outer surface of the monitoring box 2. These ventilation holes facilitate heat dissipation inside the monitoring box 2, preventing overheating of internal components.

[0038] Several fixed side plates 6 are installed on the sides of the monitoring box 2, and several fixing holes 7 are formed on each fixed side plate 6. The fixed side plates 6 and fixing holes 7 facilitate the installation and fixation of the monitoring box 2 when feeding materials into the electrolytic cell.

[0039] This utility model provides a lifting device structure, including a screw lifter 1 and an alarm device. The alarm device is connected to the top of the screw lifter 1, and a busbar connecting plate 3 is provided at the bottom movable end of the screw lifter 1, which can be connected to the horizontal busbar of the electrolytic cell. The busbar connecting plate 3 can be connected to the horizontal busbar, thereby driving the anode to move up and down. Under the action of the alarm device, the screw lifter 1 is prevented from being damaged by the long angle of the anode.

[0040] The screw jack 1 is bolted to the upper beam of the electrolytic cell, and a spring washer is provided between the bolt and the base of the screw jack 1. The spring washer creates a buffer space between the fixing bolt and the screw jack 1.

[0041] Working Principle: The monitoring box is installed next to the screw jack. Limit switches monitor the upper position of the screw jack. After the anode angle is extended, the screw jack encounters resistance during the lowering of the busbar and is pushed upwards. When the entire screw jack is pushed upwards, it shifts upwards, triggering the limit switches and controlling the audible and visual alarm to alert personnel and prevent damage from prolonged lifting. This significantly improves the practicality of the alarm device. A signal transmission module inside the monitoring box transmits the screw jack displacement information collected by the limit switches to an external control unit, allowing personnel to be alerted via external warning lights, further enhancing the device's convenience. A protective reinforcement plate installed outside the monitoring box increases its overall strength and pressure resistance, making it less prone to damage. An insulating plate inside the monitoring box prevents leakage and also protects against electrostatic interference, improving operational stability.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
