Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, specifically to a roasting device for an electrolytic cell. Background Technology

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode. Most electrolytic cells use a diaphragm to separate the anode chamber and the cathode chamber. Based on the type of electrolyte, they are classified into three types: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells.

[0003] The calcination device of the electrolytic cell is one of the key pieces of equipment in aluminum electrolysis production. It is mainly used to calcine the cathode carbon block and surrounding structure at high temperature before the electrolytic cell is started, so that it forms a dense carbonaceous whole, reduces resistance and prevents electrolyte penetration, thereby extending the life of the electrolytic cell and improving operating efficiency. Existing calcination devices generally heat the cathode and anode inside the electrolytic cell by heating the resistance wire. However, during the heating process, local overheating can easily occur in the internal area of ​​the electrolytic cell, resulting in an imbalance of internal temperature and affecting normal use. Utility Model Content

[0004] The purpose of this invention is to provide a calcination apparatus for an electrolytic cell to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a calcination device for an electrolytic cell, comprising an electrolytic cell, wherein an anode carbon block and an anode carbon block are disposed inside the electrolytic cell, and a plurality of grooves are equidistantly provided on the side wall of the electrolytic cell, wherein a metal rod is installed inside the groove, and an installation groove is provided at the upper end of the metal rod, wherein a resistance rod is installed inside the installation groove, and a heating component is jointly installed at the upper end of the plurality of resistance rods, wherein the heating component is connected to an external power supply, and a plurality of temperature sensors are equidistantly installed on the inner side wall of the electrolytic cell.

[0006] Preferably, multiple side plates are equidistantly installed on the left and right side walls of the electrolytic cell, and an electric push rod is installed on the upper end of the side plate. A lifting plate is installed on the left and right side walls of the heating assembly, and multiple snap-fit ​​slots are equidistantly opened on the lower end of the lifting plate. The multiple snap-fit ​​slots are snap-fitted to the multiple electric push rods.

[0007] Preferably, the heating assembly includes a horizontal plate, a vertical plate, an extension block, a plug, and a slot. Slots are provided on both sides of the upper end of the two horizontal plates. Two vertical plates are symmetrically connected to the upper ends of the two horizontal plates. Extension blocks are installed at both ends of the vertical plates. The extension blocks at both ends of the vertical plates are respectively connected to the two slots. A plug is installed at the lower end of the extension blocks. The plug is electrically connected to the internal interface of the slot.

[0008] Preferably, both the horizontal and vertical plates are equipped with wires, which are connected to multiple resistance rods, and each connection point between the wires and the multiple resistance rods is equipped with an independent switch.

[0009] Preferably, a partition is installed at the center of the electrolytic cell, and multiple through slots are provided on the side wall of the partition. Cooling pipes are installed inside the partition and pass through the multiple through slots in sequence.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The calcination device for the electrolytic cell of this invention uses an external power source to energize the internal wires of the heating component, thereby electrically heating multiple resistance rods below the heating component. These resistance rods conduct heat to an external metal rod, which in turn heats the electrolyte inside the electrolytic cell, and consequently, the anode and cathode carbon blocks. Multiple temperature sensors continuously monitor the internal temperature of the electrolytic cell. When any area becomes too hot, the temperature sensor sends data to an external control platform. The external control platform then operates the control switch for the corresponding area to disconnect the electrical connection between the wires and the resistance rods, thus stopping the heating of the resistance rods and metal rods. The multiple metal rods can heat the inside of the electrolytic cell relatively evenly. The external control platform intelligently controls the heating process of the resistance rods and metal rods inside the electrolytic cell, thus preventing excessively high temperatures in certain areas.

[0017] 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.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 3 As shown, the calcination apparatus of the electrolytic cell in this embodiment includes an electrolytic cell 1. An anode carbon block and an anode carbon block are disposed inside the electrolytic cell 1. The anode carbon block and the anode carbon block are existing structures. Multiple grooves are equidistantly spaced on the sidewall of the electrolytic cell 1. Metal rods 2 are installed inside the grooves, and the metal rods 2 and the grooves are slidably connected, allowing for free disassembly and installation. The metal rods 2 are made of an aluminum-copper alloy, which has high thermal conductivity. An installation groove 3 is formed at the upper end of the metal rods 2, and a resistance rod 5 is installed inside the installation groove 3. A heating assembly 4 is installed at the upper end of multiple resistance rods 5. The heating assembly 4 is connected to an external power source, and the external power source powers the heating assembly. When component 4 is powered on, the heating component 4 electrically heats the resistance rod 5. The resistance rod 5 conducts heat to the connected metal rod 2. Multiple temperature sensors 11 are installed at equal intervals on the inner sidewall of the electrolytic cell 1. The external power supply and the temperature sensors 11 are both connected to the external control platform via Bluetooth. The internal temperature of the electrolytic cell 1 is monitored in real time by multiple temperature sensors 11. When the temperature in any area is too high, the temperature sensor 11 will send the data to the external control platform. The external control platform will operate the control switch of the corresponding area to disconnect the electrical connection between the wire of the corresponding area and the resistance rod 5, thereby stopping the heating of the resistance rod 5 and the metal rod 2.

[0020] Specifically, multiple side plates 7 are equidistantly installed on the left and right side walls of the electrolytic cell 1. An electric push rod 8 is installed on the upper end of the side plate 7. A lifting plate 9 is installed on the left and right side walls of the heating component 4. Multiple snap-fit ​​slots 10 are equidistantly opened on the lower end of the lifting plate 9. The multiple snap-fit ​​slots 10 are snap-fitted to the multiple electric push rods 8. The electric push rods 8 can drive the lifting plate 9 to move up and down. The two lifting plates 9 are connected to the heating component 4 and can drive the heating component 4 to move up and down. When the heating component 4 is lifted, it will drive multiple resistance rods 5 to detach from the metal rod 2. At this time, the user can disassemble and install the metal rod 2 as needed.

[0021] Furthermore, the heating assembly 4 includes horizontal plates 401, vertical plates 402, extension blocks 403, plugs, and slots 405. Slots 405 are provided on both sides of the upper end of the two horizontal plates 401. Two vertical plates 402 are symmetrically connected to the upper ends of the two horizontal plates 401. Extension blocks 403 are installed at both ends of the vertical plates 402, and the extension blocks 403 at both ends of the vertical plates 402 are respectively connected to the two slots 405. A plug is installed at the lower end of the extension blocks 403, and the plug is connected to the slot. The internal interface 404 is electrically connected to the 405. The longitudinal plate 402 and the transverse plate 401 are connected by a snap-fit ​​and are detachable. The longitudinal plate 402 and the transverse plate 401 are electrically connected through a plug and a slot 405. Both the transverse plate 401 and the longitudinal plate 402 have wires installed inside. The wires are connected to multiple resistance rods 5. An external power supply can energize the wires inside the transverse plate 401 and the longitudinal plate 402. The energized wires will heat the multiple resistance rods 5.

[0022] Furthermore, a partition 12 is installed at the center of the electrolytic cell 1. Multiple through slots 13 are opened on the side wall of the partition 12. Cooling pipes 14 are installed inside the partition 12 and pass through the multiple through slots 13 in sequence. The cooling pipes 14 are connected to an external water source, which can send coolant into the interior of the cooling pipes 14 and form a circuit. The external water source is electrically connected to an external control platform. The external control platform can control the external water source. When multiple temperature sensors 11 detect that the temperature inside the electrolytic cell 1 is too high, they will transmit a signal to the external control platform. The external control platform will control the external water source to inject coolant into the cooling pipes 14 to cool the interior of the electrolytic cell 1.

[0023] Furthermore, two liquid injection ports 6 are symmetrically opened at the upper end of the electrolytic cell 1. The two liquid injection ports 6 are located on the left and right sides of the partition plate 12, respectively. The two liquid injection ports 6 can inject electrolyte or electrolyte solution into the electrolytic cell 1.

[0024] The method of use in this embodiment is as follows: An external power source energizes the internal wires of the heating assembly 4 to electrically heat multiple resistance rods 5 below the heating assembly 4. The resistance rods 5 conduct heat to the external metal rods 2, which in turn heat the electrolyte inside the electrolytic cell 1, thereby heating the anode and cathode carbon blocks. Multiple temperature sensors 11 continuously monitor the internal temperature of the electrolytic cell 1. When the temperature in any area becomes too high, the temperature sensor 11 sends data to an external control platform. The external control platform then operates the control switch for the corresponding area to disconnect the electrical connection between the wires in that area and the resistance rods 5, thus stopping the heating of the resistance rods 5 and the metal rods 2. The multiple metal rods 2 can heat the inside of the electrolytic cell 1 relatively evenly. The external control platform intelligently controls the heating process of the resistance rods 5 and the metal rods 2 inside the electrolytic cell 1, thereby preventing the phenomenon of excessively high temperatures in some areas.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
