Description
Technical Field
[0001] The utility model relates to the technical field of aluminum electrolysis equipment, in particular to an electrolyte detection device in an aluminum electrolysis tank. Background Art
[0002] In the current domestic aluminum electrolytic cell production, as the production continues, the electrolyte in the aluminum electrolytic cell is gradually consumed. Since a sealed shell surface layer will be formed on the upper part of the aluminum electrolytic cell, when it is necessary to add raw materials to the aluminum electrolytic cell, a punching device is generally used to penetrate a feed opening at a fixed position on the shell surface layer for feeding, and then the operator observes with the naked eye whether it is penetrated. However, the aluminum electrolytic cell production process is high temperature, and the electrolyte is highly corrosive, which brings great difficulties to the operator to observe whether the feed opening is penetrated. In view of this, the present application provides an electrolyte detection device in an aluminum electrolytic cell, which detects the electrolyte in the aluminum electrolytic cell and accurately determines whether the feed opening is penetrated. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the shortcomings of the above-mentioned background technology, and provides an electrolyte detection device in an aluminum electrolytic cell, comprising an aluminum electrolytic cell, a shelling mechanism and a detection power supply, wherein the aluminum electrolytic cell comprises an electrolytic aluminum liquid layer, an electrolyte layer and a shell surface layer sequentially distributed from bottom to top, and a feed opening for replenishing electrolyte into the electrolyte layer of the aluminum electrolytic cell is provided on the shell surface layer, the shelling mechanism comprises a conductive shelling head and a driving member, the conductive shelling head is connected to the driving end of the driving member, the conductive shelling head corresponds to the feed opening and is used to penetrate the feed opening on the shell surface layer to the electrolyte layer, and the two ends of the detection power supply are respectively connected to the electrolytic aluminum liquid layer and the conductive shelling head.
[0004] Preferably, a cathode steel rod is provided on the side wall of the electrolytic aluminum liquid layer, and the electrolytic aluminum liquid layer is connected to the detection power supply through the cathode steel rod.
[0005] Preferably, the detection power supply is connected to an end of the conductive shelling head close to the driving end of the driving member.
[0006] Preferably, the detection power supply is one of a constant current power supply and a constant voltage power supply.
[0007] Preferably, the driving member is a driving cylinder.
[0008] Compared with the prior art, the utility model provides an electrolyte detection device in an aluminum electrolytic cell, which connects the positive electrode of the detection power supply to the electrolytic aluminum liquid layer, and the positive electrode of the detection power supply to the conductive shelling head. Since the conductive shelling head, the electrolyte layer and the electrolytic aluminum liquid layer are all conductive, and the shell surface layer is not conductive, when the lower end of the conductive shelling head contacts the electrolyte layer, the detection power supply, the electrolytic aluminum liquid layer, the electrolyte layer and the conductive shelling head will form a closed circuit, that is, when the conductive shelling head is driven by the driving member to shell at the feeding port position and penetrate the feeding port to the electrolyte layer, the lower end of the conductive shelling head will contact the liquid surface of the electrolyte layer, and the detection power supply will detect that the circuit is connected. Therefore, based on the device, the detection of the electrolyte in the aluminum electrolytic cell can accurately determine whether the feeding port on the shell surface layer is through, and the operator does not need to observe and judge with the naked eye. On the one hand, it reduces the labor intensity of the operator and avoids the operation risk. On the other hand, it also greatly improves the judgment accuracy, and has the characteristics of simple structure and high detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0012] like Figure 1 As shown, the utility model provides an electrolyte detection device in an aluminum electrolytic cell, comprising an aluminum electrolytic cell, a shelling mechanism and a detection power supply 5, wherein the aluminum electrolytic cell comprises an electrolytic aluminum liquid layer 1, an electrolyte layer 2 and a shell surface layer 3 which are sequentially distributed from bottom to top, and a feed opening 43 for replenishing electrolyte into the electrolyte layer 2 of the aluminum electrolytic cell is provided on the shell surface layer 3, and the shelling mechanism comprises a conductive shelling head 41 and a driving member 42, the conductive shelling head 41 is connected to the driving end of the driving member 42, and the conductive shelling head 41 corresponds to the feed opening 43 for penetrating the feed opening 43 on the shell surface layer 3 to the electrolyte layer 2, and the two ends of the detection power supply 5 are respectively connected to the electrolytic aluminum liquid layer 1 and the conductive shelling head 41.
[0013] In this embodiment, the driving member 42 is a driving cylinder, and the driving end of the driving cylinder is fixedly connected to the upper end of the conductive shelling head 41 to drive the conductive shelling head 41 to extend and retract, thereby achieving shelling of the shell surface layer 3 to obtain a discharge port 43 that passes through the inner cavity of the aluminum electrolytic cell and the outside, and discharges materials into the aluminum electrolytic cell through the discharge port 43; the conductive shelling head 41 is a shelling head made of conductive material.
[0014] The detection power supply 5 is a constant current power supply or a constant voltage power supply. Considering the existence of back electromotive force in the aluminum electrolytic cell, in order to ensure the accuracy of detection, the detection power supply 5 in this embodiment selects a constant current power supply.
[0015] In this embodiment, the negative electrode of the detection power supply 5 is connected to the electrolytic aluminum liquid layer 1, and the positive electrode of the detection power supply 5 is connected to the conductive shelling head 41. Since the conductive shelling head 41, the electrolyte layer 2 and the electrolytic aluminum liquid layer 3 are all conductive, and the shell surface layer 3 is not conductive, when the lower end of the conductive shelling head 41 contacts the electrolyte layer 2, the detection power supply 5, the electrolytic aluminum liquid layer 1, the electrolyte layer 2 and the conductive shelling head 41 will form a closed circuit, that is, when the conductive shelling head 41 is driven by the driving member 42 to shell at the discharge port 43 until it penetrates the discharge port 43 to the electrolyte layer 2, the lower end of the conductive shelling head 41 will contact the liquid surface of the electrolyte layer 2, and the detection power supply 5 will display that the circuit is connected. Therefore, based on the detection of the electrolyte in the aluminum electrolytic cell by the device, it is possible to accurately determine whether the discharge port 43 on the shell surface layer 41 is through, without the need for the operator to observe and judge with the naked eye. On the one hand, it reduces the labor intensity of the operator and avoids operational risks. On the other hand, it greatly improves the accuracy of judgment and has the characteristics of simple structure and high detection efficiency.
[0016] like Figure 1 As shown, the side wall of the electrolytic aluminum liquid layer 1 is provided with a cathode steel rod 6, and the electrolytic aluminum liquid layer 1 is connected to the detection power supply 5 through the cathode steel rod 6.
[0017] In this embodiment, since the cathode steel rod 6 is arranged on the side wall of the electrolytic aluminum liquid layer 1 at the lower part of the aluminum electrolysis cell, the negative electrode of the detection power supply 5 is connected to the cathode steel rod 6, thereby improving the connection efficiency between the components.
[0018] The detection power supply 5 is connected to an end of the conductive shelling head 41 close to the driving end of the driving member 42 .
[0019] In this embodiment, considering that the end of the conductive shelling head 41 away from the driving end of the driving member 42 will shell to the electrolyte layer 2, the positive electrode of the detection power supply 5 is connected to the end of the conductive shelling head 41 close to the driving end of the driving member 42 to prevent the connecting line between the detection power supply 5 and the conductive shelling head 41 from being corroded or damaged by friction of the shell surface layer 3 during the shelling process.
[0020] The two ends of the detection power supply 5 are detachably connected to the electrolytic aluminum liquid layer 1 and the conductive shelling head 2 through power lines, thereby facilitating the disassembly, assembly and maintenance of the detection device.
